Fixing device used for installing shock absorbing safety bin ventilating device

Abstract

The invention discloses a fixing device used for installing a shock absorbing safety bin ventilating device. The fixing device comprises a fixing structure and a fixing top frame. The fixing top frameis connected to the bottom of the fixing structure in a clamped manner. The fixing structure comprises a limiting clamping groove, a first reset spring, a reset top plate, a bottom fixing frame, an interlocking clamping groove, a limiting safety pin, a first clamping groove, a second clamping groove, a second reset spring, an interlocking sliding block, a limiting groove, a fixing supporting rod,an interlocking rod, a limiting sliding sleeve, a fixing screw, a limiting lock rod, a third reset spring, a connecting ring, a fixing lock hook, a fourth reset spring and an exhausting groove. The fixing device has the beneficial effects that by arranging the fixing structure, when the fixing lock hook is separated from the connecting ring, the third reset spring drives the limiting lock rod tobe inserted into the first clamping groove in the top of the limiting safety pin, then the fixing screw is screwed to fix the limiting lock rod, in the disassembling process, only the limiting safetypin is pulled, assembling and disassembling are more convenient and rapid, time and labor are saved, and the maintenance time is saved.

Description

technical field [0001] The invention relates to the technical field of fixing devices, in particular to a fixing device for installing a ventilation device of a shock-absorbing safety cabin. Background technique [0002] Earthquakes may cause secondary disasters such as tsunamis, landslides, collapses, and ground fissures. After an earthquake, emergency shelters are often needed. Therefore, shock-absorbing safety cabins are widely used. In order to maintain internal air circulation, shock-absorbing safety cabins need to be installed with ventilation devices. , the installation of the existing ventilation device requires bolt fastening, and the existing installation method is single and rigid, which cannot make its installation and disassembly more convenient and convenient, takes a lot of time and effort, and cannot save maintenance time. Contents of the invention [0003] The object of the present invention is to provide a fixing device for installing a ventilation device...
