قفل برقی دکاشاپ

قفل برقی ایرانی یا خارجی؟
انواع موجود در بازار به دو نوع خارجی (ایتالیایی) و ایرانی تقسیم بندی می شود. این نکته قابل ذکر است که کیفیت قفل های برقی ایتالیایی از هم نوع ایرانی و تولید داخل بسیار بیشتر است. طبق آمار فروش این محصول در کشور مدل بیشترین استفاده را در بین مشتریان داشته است که البته محصولات مشابه داخلی نیز چند سالی است که تولید می شود و به دلیل قیمت تمام شده پایین مورد استفاده زیادی قرار میگیرد. باید در نظر داشت که قفل های برقی مشکی بزرگ که دکمه قرمز رنگ روی آن قرار دارد (کله گاوی) دارای صدای بسیار پایین در هنگام باز و بسته شدن درب به نسبت دیگر قفل های برقی می باشد و در کل قفل برقی که شبیه ایزو می باشد و به صورت مربع است دارای صدای زیاد و طول عمر کمتر نسبت به قفل های کله گاوی می باشد.
با توجه به شرایط خاصی که دارند مورد استفاده قرار می گیرند، به عنوان مثال اگر محدودیت ارتفاع داشته باشیم از راهبند تاشو می توانیم استفاده کنیم که فضای بسیار کمی از ارتفاع را اشغال می کند. راهبند معمولا از یک بوم با اندازه های متغییر، یک بدنه محکم و ضد خش، یک پایه نگهدارنده، فلاشر روی بدنه، یک جفت فتوسل و موتور و مدارفرمان تشکیل شده است که در بعضی مواقع به صورت نیم ست به مصرف کننده ارائه می گردد یا قیمت تمام شده پایین تر باشد.
موارد استفاده از و یا همان جک درب پارکینگ دارای تنوع بالایی می باشد که در کشور عزیزمان ایران بیشتر به صورت جک های دو لنگه پروانه ای، مدل های کشویی و همچنین به صورت تک لنگه مورد استفاده قرار می گیرد.
برند های معتبر خارجی در کشور ما موجود می باشد و همچنین باید بدانید که تولیدات محصول جک درب پارکینگ ایرانی نیز بسیار باتنوع بالا موجود می باشد

۱۴ of the Weirdest Things You Can Buy on Amazon

Amazon is the go-to destination for electronics, snacks, clothes, and so much more. But there’s a dark side of Amazon—an oft unvisited zone, where uranium, fire ants, wooden cabins, and UFO detectors all come with free shipping.
We’re going to take you into that zone, and you might even come out with a few purchases. Here are 14 things you didn’t know you could buy on Amazon.
Unrefined Uranium Oxide
Lifete
If you haven’t added unrefined uranium oxide to your Amazon wishlist or wedding registry, then clearly, you have no idea what you’re doing! It emits ionizing radiation and causes Geiger counters to scream in agony. And despite what anyone else might tell you, this guy on Yahoo Answers says you can own uranium without a license.
Sadly, Amazon doesn’t sell enriched uranium or plutonium. But hey—maybe someday!

It’s Radioactive!

Rare earth uranium oxide, high grade unrefined uranium ore uraninite, for Geiger counter & radiation detector test source!

This unrefined uranium oxide is the perfect conversation piece. Sure, it’s radioactive, but it’s also super neat.

Lou-Wheeze the Flexible Latex Lung Model
HEALTH EDCO
Believe it or not, Amazon can scare you straight. They sell an educational cardboard cutout named, Lou-Wheeze—a woman with one perfect lung and one crappy lung.
Why does Lou-Wheeze expose her lungs? Well, she’s an inanimate educational resource you can use to teach your kids (or yourself, or your parents) what happens when you only inhale smoke through one nostril (you end up with one really crappy lung).

A Wonderful Education Tool

HEALTH EDCO W43062 Lou-Wheeze Flexible Latex Lung Model, 17″ Length x 23″ Height

Lou-Wheeze shows kids the difference between a healthy lung and a diseased lung. She makes for a wonderful educational tool or spooky Halloween decoration.

What Can I Do with My Old iPhone?

Your old iPhone doesn’t become useless as soon as you get a new one. Don’t just throw it in a drawer—you can sell it, recycle it, or turn it into something cool!
Sell It, Donate It, or Recycle It
Even if you don’t usually sell your old electronics, you should consider selling your old iPhone. They retain considerably more value than their Android counterparts. Thanks to the allure of the Apple ecosystem, solid construction, and Apple’s continued commitment to old devices through iOS updates, an old iPhone is a great choice for many consumers.
You could also give your iPhone to a friend or relative you think would appreciate it. You could make their whole week! Just be sure to back up your data, and then erase everything under Settings > General > Reset.
An old iPhone is also an excellent first or second smartphone for kids and teenagers. Don’t forget to set up the parental control app Screen Time if you go this route.
If your old iPhone doesn’t work well, consider recycling it. You can also try to sell it on eBay. Someone who wants to scrap it for spare parts might buy it, but if it’s not functional, you might not get much money for it.
Apple takes old iPhones off your hands, and you might even get some Apple Store credit for it through the Apple Trade In program. You can either drop it off at your local Apple retail store or mail it in.
If none of these ideas appeal to you, there are many other ways you can recycle your old iPhone.
Jailbreak It

How to Stream UFC 242 Khabib vs. Poirier Live Online

UFC
For the first time, UFC plays out in the United Arab Emirates on Saturday, September 7. In this highly anticipated lightweight title unification bout, champion Khabib Nurmagomedov takes on interim champion Dustin Poirier. Here’s how to watch.
How to Watch the Fight Live in the United States
UFC 242 is exclusive to ESPN+, ESPN’s streaming service, in the United States, so the only way to watch the fight live is online. For that, you’ll have to sign up for ESPN+ and then purchase the fight as a pay-per-view event.
Coverage of the main fight card begins at 2:00 PM Eastern Time (US) and early prelims start at 10:00 AM Eastern Time (US).
ESPN+ typically runs $4.99 per month, though you can sign up for a free seven-day trial. To watch UFC 242 live, you’ll need to pony up an additional $60.
If you’re a new subscriber to ESPN+, you can also buy UFC 242 PPV along with a one-year ESPN+ subscription for $79.99.
At this time, there’s no way to watch the fight live over cable TV or through any other streaming service in the US. You can watch the prelims in the US (and the main card outside the US) through UFC’s FIGHT PASS.
Having Issues Bypassing Geographic Restrictions? Use a VPN
Whether you’re traveling from your home country or live in a place that has ridiculous restrictions on what’s available, the solution to bypassing restrictions is always to use a VPN, which will make it appear as if you are coming from a different location. Our VPN picks are these:
ExpressVPN: This VPN choice is incredibly fast, easy to use, and has very user-friendly clients for every platform. Here’s how to watch the fight:

Download Express VPN.
Connect to a server located in the U.S if you want to use ESPN+ or to a server located where UFC TV is available if you’re going to watch that way.
Head to ESPN+ and purchase the fight. You will need to supply a valid ZIP code.

StrongVPN: This VPN isn’t quite as user-friendly, but is very fast and tends to be useful for bypassing restrictions because it’s not quite as well known.
