[0002] With the increase in fire and electricity consumption in modern households, the frequency of household fires is increasing. Once a household fire occurs, it is easy to encounter unfavorable factors such as untimely firefighting, lack of fire-fighting equipment, panic among the people present, and slow escape, which ultimately leads to significant loss of life and property. According to the characteristics of household fires and fire prevention measures, installing fire alarms is of practical significance for preventing household fires and reducing fire losses.

[0003] The importance of existing fire alarms is self-evident. Therefore, in order to ensure their sensitive sensitivity, they are generally tested one by one after production. When testing existing fire alarms, the staff usually places the alarm on the testing platform and manually turns the buckle to fix it, so as to ensure the stability during the test. However, this method is too cumbersome for the disassembly of the fire alarm during installation, resulting in reduced replacement efficiency and affecting the test speed.

[0004] Therefore, a quick crimping test mechanism for fire alarms that can improve installation and disassembly efficiency is now designed to solve such defects. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a quick crimping test mechanism for a fire alarm, which solves the problem that the existing fire alarm cannot be conveniently installed and fixed during testing.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a quick crimping test mechanism for a fire alarm, comprising an upper locking plate used in conjunction with a base plate, the upper locking plate being located at the upper part of the base plate, the front and rear parts on both sides of the top of the base plate being fixedly connected to a guide slide rod through a fixing block, the front and rear parts on both sides of the top of the upper locking plate being fixedly connected to a guide slide sleeve through an opening, and the guide slide sleeve being slidably installed on the surface of the guide slide rod.

[0007] Preferably, both sides of the top of the base plate and the inner side of the upper locking plate are fixedly connected with test probes through openings, and there are several test probes. A reset spring is fixedly connected between the base plate and the upper locking plate, and there are several reset springs.

[0008] Preferably, the front and rear parts of both inner sides of the upper locking plate are provided with rotation slots, the inner side of the rotation slots are rotatably connected with arc-shaped hooks through a rotating member, and the opposite sides of the arc-shaped hooks on both sides are fixedly connected with load-bearing pressure blocks.

[0009] Preferably, the front and rear parts of both sides of the top of the base plate are fixedly connected with side stop blocks used in conjunction with the arc-shaped hooks through openings.

[0010] Preferably, the front and rear portions of both sides of the top of the upper locking plate are fixedly connected with U-shaped blocking blocks used in conjunction with the arc-shaped hooks.

[0011] Preferably, the front and rear parts of the bottom of the base plate are fixedly connected with self-locking devices used in conjunction with the upper locking plate through openings.

[0012] Beneficial Effects

[0013] The utility model provides a quick crimping test mechanism for fire alarms. Compared with the existing technology, it has the following beneficial effects:

[0014] (1) The fire alarm quick crimping test mechanism is used to slide an upper locking plate on the top of the base plate using a guide slide rod and a guide slide sleeve, and is used in conjunction with a reset spring and a self-locking device. The arrangement of these structures enables the alarm to dock with the arc-shaped hook and then use the downward pressure to fix the upper locking plate and the alarm. When disassembling, it is only necessary to press the self-locking device again to unlock it. The whole process is convenient, fast and quick, which can improve the speed of installation, disassembly and replacement of the alarm and ensure production efficiency.

[0015] (2) The quick crimping test mechanism for fire alarms has side stop blocks installed on both sides of the top of the base plate for use with the arc-shaped hooks, and is used in conjunction with U-shaped blocks. The arrangement of these structures can effectively prevent the arc-shaped hook from rotating after it has latched onto the alarm and lowered, by blocking the side stop blocks. At the same time, after disassembly, the arc-shaped hook can be opened to a suitable angle by blocking the U-shaped block, thereby facilitating the installation of the alarm, making the equipment stable and satisfying current use.
