Hook assembly for anti-theft safety door ground lock device and ground hook device thereof

Abstract

The invention relates to a hook assembly and a ground hook device of a ground lock device for an anti-theft safety door, belonging to the technical field of rolling gates, including a box body, which is characterized in that: the box body is hollow and has a triangular prism structure, and the prism in the length direction of the triangular prism There is a hook entrance for insertion and cooperation with the hook on the side, and there are locking runners and overhead paddles for opening and closing on the left and right sides of the hook inlet. The locking runner is installed on the inner wall of the box through the runner pivot. The overhead pick is mounted on the inner wall of the box via a pick pivot. The present invention has a simple structure, fewer matching components, very convenient assembly and maintenance, and low production and maintenance costs while ensuring improved safety performance.

Description

technical field [0001] The invention relates to a hook assembly of a ground lock device for an anti-theft safety door and a ground hook device thereof, belonging to the technical field of rolling gates. Background technique [0002] The application of current rolling gate is more and more extensive, and when applying, the anti-theft ground lock and ground hook of its rolling gate are indispensable. [0003] Before this application, some applicants have improved their anti-theft ground locks to further improve the safety performance. The application number is 201120081633.1, and the name is a locking mechanism for rolling shutter door and window locks; there is another application number 201120087278.9 , the name is a power control mechanism for electric rolling shutter door and window locks. [0004] Compared with the existing technology, the above two technologies have been further improved in terms of safety performance, but their structures are more complicated, and ther...

Problems solved by technology

[0004] Compared with the existing technology, the above two technologies have been further improved in terms of safety performance, but their structures are more complicated, and there are many matching components, which brings inconvenience to assembly and maintenance; the locking and matching parts used in the above technologies are located underground , during the installation process, it is necessary to open a deep groove on the ground (the required groove depth is about 7cm), this groove is used to install the ground hook device, if the groove is opened on the ground with floor heating or ground wire, it is easy to damage the floor heating or ground wire (especially when the safety door is retrofitted, it is easy to damage the floor heating or ground wire)
