Cooperating structure of independent fire detector and mounting plate

Abstract

The invention provides an independent fire detector and a mounting plate matching structure and a matching method thereof, including a detector shell and a mounting plate shell, the diameter of the mounting plate shell is smaller than the detector shell, and the end of the side wall of the mounting plate shell is provided with an outer Turned edge structure, the edge structure is provided with a gap, the gap is provided with a shaft, the shaft is covered with a sleeve, the sleeve is connected to the swing rod, the sleeve is connected to the middle section of the swing rod, and the top of the swing rod is provided with a convex The inner side wall of the detector is provided with ribs, the number and relative position of the ribs on the inner side wall of the detector are the same as those of the notches, and the inner side of the bottom of the swing rod is provided with a spring supported on the housing of the mounting plate. The existing screw connection is changed, the mounting plate and the detector are integral structures, there is no external structure, and it is not easy to lose during the packaging process. When installing, only need to face the mounting plate and the detector and engage with each other to complete the connection , Simple structure and convenient installation.

Description

technical field [0001] The invention belongs to the technical field of electronic product structure and relates to an independent fire detector. Background technique [0002] With the rapid development of fire alarm systems, the demand for independent fire detectors in ordinary households is also increasing. At present, most independent detectors on the market use 9V, 3.6V, 3V batteries, which are costly and difficult to obtain in the market. Purchased, the user has the problem of difficulty in battery replacement. And most of them use springs or add multiple parts to realize the function of obvious warning signs when the battery is taken away, the assembly procedure is complicated and the assembly efficiency is reduced. In addition, the matching expansion tubes and self-tapping screws are usually put into a ziplock bag and sent to the user with the detector, which is easy to lose or forget, making it impossible to fix the mounting plate. When fixing the detector and the m...

[0002] With the rapid development of fire alarm systems, the demand for independent fire detectors in ordinary households is also increasing. At present, most independent detectors on the market use 9V, 3.6V, 3V batteries, which are costly and difficult to obtain in the market. Purchased, the user has the problem of difficult battery replacement

And most of them use springs or add multiple parts to realize the function of obvious warning signs when the battery is taken away, the assembly procedure is complicated and the assembly efficiency is reduced

In addition, the matching expansion tubes and self-tapping screws are usually put into a ziplock bag and sent to the user with the detector, which is easy to lose or forget, resulting in the failure to fix the mounting plate

When fixing the detector and the mounting plate, it is often impossible to judge whether the rotation is in place, resulting in poor assembly firmness
