AI Technical Summary

Technical Problem

When used outdoors, the waterproof sealing ring of existing electronic padlocks is prone to loosening, which leads to a decrease in waterproof performance. In addition, the existing waterproof sealing ring is not firmly attached and is easily corroded by outdoor water, affecting the service life of the internal components of the lock case.

Method used

A double sealing structure is set on the outside of the lock housing, including a sealing sleeve and a seepage-proof cylinder. The sealing connection between the lock handle and the lock housing is achieved by sealing rings and rubber kits. The outer surface of the sealing sleeve and seepage-proof cylinder is provided with threaded mounting holes and screws for fixing to ensure sealing. An explosion-proof intrinsically safe controller and an explosion-proof potting cover are used to protect the internal components.

Benefits of technology

It effectively prevents rainwater from penetrating into the lock case, protecting internal components, improving the lock case's waterproof performance and service life, and facilitating the replacement and maintenance of sealing components.

Abstract

This utility model provides an explosion-proof wireless electronic padlock, including a lock shell and a handle. The top surface of the lock shell has handle holes at both ends, and a protective platform is fixed to the top of each handle hole. Both ends of the handle extend into the lock shell from the protective platform and the handle hole, respectively. A waterproofing component is installed on the top of the protective platform. This utility model has the following advantages: the sealing ring can effectively wrap around the outer surface of the waterproofing component, thus ensuring a proper seal at the connection between the handle and the handle hole. After the connection is completed, the lock shell and handle are sealed. When using the electronic padlock outdoors, rainwater falling between the lock shell and handle is effectively prevented from seeping into the lock shell through the gap between the handle and the handle hole, thus protecting the internal electronic components and extending the lifespan of the wireless electronic padlock.
