Technical Field

[0001] This utility model relates to the field of fire alarm button technology, specifically a fire alarm button that is easy to maintain. Background Technology

[0002] In the field of fire safety, fire alarm buttons, as key front-end alarm devices, are an important line of defense for timely detection and transmission of fire information. When a fire breaks out in its early stages, before smoke and heat trigger automatic fire detectors, personnel can manually press the alarm button to quickly send an alert to the fire control center, buying valuable time for firefighting and rescue efforts, effectively curbing the spread of fire, and reducing loss of life and property. They are widely used in various public places, such as shopping malls, schools, hospitals, office buildings, and other densely populated areas, as well as industrial plants, warehouses, and other places with high fire hazards, and are one of the basic configurations for ensuring fire safety.

[0003] However, traditional fire alarm buttons present many challenges in maintenance, making it difficult to meet the efficiency and reliability requirements of modern fire safety management. From a structural design perspective, many fire alarm buttons use an integrated, enclosed casing. If a component inside, such as a microswitch or circuit board solder joint, malfunctions, maintenance personnel need to use tools to pry open the casing. This process can easily damage the casing, making it impossible to reinstall and restore it.

[0004] To address the aforementioned issues, we propose a fire alarm button that is easy to maintain. Utility Model Content

[0005] To address the technical problem that existing fire alarm buttons require tools to pry open the casing, which can easily damage the casing and prevent reinstallation, this invention provides a fire alarm button that is easy to maintain.

[0006] This utility model is achieved using the following technical solution: a fire alarm button that is easy to maintain, comprising a housing and a base. The housing is installed on the outside of the base. Two grooves are machined on both sides of the housing. A pressing block is movably connected inside the grooves. A connecting block is fixedly connected to the bottom of the pressing block. A locking block is fixedly connected to one end of the connecting block. Two slots are machined on both sides of the base. The locking block is plugged into the slot. A fixing block is fixedly connected to the inner wall of the housing. A side plate is fixedly connected to one end of the fixing block. A limit rod is fixedly connected to one side of the side plate. One end of the limit rod is movably connected to the inside of the pressing block. Multiple edge strips are fixedly connected around the bottom of the base. The bottom of the housing fits against the top of the edge strips.

[0007] Preferably, the top of the pressing block is fixedly connected to a slider, the bottom of the fixed block is machined with a groove, and the slider is movably connected inside the groove.

[0008] Preferably, the top of the slider is fixedly connected to a limiting block, the top of the slide groove is machined with a limiting groove, and the limiting block is movably connected inside the limiting groove.

[0009] Preferably, the pressing block has a movable groove inside, and one end of the limiting rod is movably connected inside the movable groove.

[0010] Preferably, one end of the limiting rod is fixedly connected to a limiting ring, and the limiting ring is movably connected inside the movable groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, this utility model uses two pressing blocks. The pressing blocks move inward along the inside of the groove, which drives the connecting block and the locking block to move, causing one end of the locking block to disengage from the inside of the slot, thereby releasing the lock between the outer shell and the base. Then, the outer shell can be moved outward, allowing the outer shell to be quickly removed for maintenance and repair. The operation is simple and convenient. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a fire alarm button that is easy to maintain includes a housing 1 and a base 2. The housing 1 is installed on the outside of the base 2. Two grooves 4 are machined on both sides of the housing 1. A pressing block 3 is movably connected inside the grooves 4. A connecting block 5 is fixedly connected to the bottom of the pressing block 3. A locking block 6 is fixedly connected to one end of the connecting block 5. Two slots 7 are machined on both sides of the base 2. The locking block 6 is plugged into the slots 7. A fixing block 8 is fixedly connected to the inner wall of the housing 1. A side plate 9 is fixedly connected to one end of the fixing block 8. A limit rod 15 is fixedly connected to one side of the side plate 9. One end of the limit rod 15 is movably connected to the inside of the pressing block 3. Multiple edge strips 201 are fixedly connected around the bottom of the base 2. The bottom of the housing 1 is in contact with the top of the edge strips 201.

[0020] When it is necessary to disassemble the outer shell 1, press the two pressing blocks 3 on both sides of the outer shell 1 at the same time. The pressing blocks 3 will move inward along the inside of the groove 4. The pressing blocks 3 will drive the connecting block 5 to move. The connecting block 5 will drive the locking block 6 to move, so that one end of the locking block 6 will disengage from the inside of the slot 7, thereby releasing the lock between the outer shell 1 and the base 2. Then move the outer shell 1 outward, so as to quickly and easily remove the outer shell 1 and facilitate maintenance and repair of the inside of the outer shell 1.

[0021] Furthermore, a slider 11 is fixedly connected to the top of the pressing block 3, and a groove 13 is machined on the bottom of the fixed block 8. The slider 11 is movably connected inside the groove 13. When the pressing block 3 moves, the pressing block 3 will drive the slider 11 to move, and the slider 11 will move along the inside of the groove 13. The groove 13 will limit the movement of the slider 11.

[0022] Furthermore, the top of the slider 11 is fixedly connected to the limiting block 12, and the top of the slide groove 13 is machined with a limiting groove 14. The limiting block 12 is movably connected inside the limiting groove 14. When the pressing block 3 drives the slider 11 to move, the slider 11 will drive the limiting block 12 to move. The limiting block 12 will move along the inside of the limiting groove 14, and the limiting groove 14 will limit the movement of the limiting block 12, so that the pressing block 3 remains stable when it moves along the inside of the groove 4.

[0023] Furthermore, the pressing block 3 has a movable groove 17 machined inside, one end of the limiting rod 15 is movably connected to the inside of the movable groove 17, and one end of the limiting rod 15 is fixedly connected to the limiting ring 16, which is movably connected to the inside of the movable groove 17.

[0024] When the pressing block 3 moves, the movable groove 17 inside the pressing block 3 will move along one end of the limiting rod 15 and the limiting ring 16. By setting the limiting rod 15, the limiting rod 15 will move along the inside of the movable groove 17, thereby limiting the movement of the pressing block 3.

[0025] Furthermore, a return spring 10 is provided on the outside of the limiting rod 15. One end of the return spring 10 is fixedly connected to the inside of the side plate 9, and the other end of the return spring 10 is fixedly connected to one side of the pressing block 3. By providing a sliding groove 13, when the pressing block 3 is pressed, the pressing block 3 will drive the return spring 10 to compress. When the pressing block 3 is released, the return spring 10 will return to its original position and extend. The return spring 10 will drive the pressing block 3 to move, so that the pressing block 3 drives the locking block 6 to insert into the inside of the locking groove 7, thereby locking the outer shell 1 on the outside of the base 2.

[0026] Working principle: By pressing the two pressing blocks 3 on both sides of the outer shell 1 at the same time, the pressing blocks 3 will move inward along the inside of the groove 4. The pressing blocks 3 will drive the connecting block 5 to move, and the connecting block 5 will drive the locking block 6 to move, so that one end of the locking block 6 is disengaged from the inside of the locking groove 7, thereby releasing the lock between the outer shell 1 and the base 2. Then, the outer shell 1 can be moved outward, so as to facilitate the quick removal of the outer shell 1 and facilitate the maintenance and repair of the inside of the outer shell 1.

[0027] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model.
