Description

Technical Field

[0001] The utility model relates to the technical field of fire alarms, in particular to a household fire prevention alarm device. Background Art

[0002] A fire alarm device is a device in an automatic fire alarm system that emits a fire alarm signal that is different from ambient sound and light. When preventing a home fire, a home fire prevention alarm device is needed.

[0003] Chinese patent document CN214042536U discloses a household fire prevention alarm device comprising a base, an air cavity defined within the base, a fan mounted within the air cavity, an air outlet pipe disposed at the bottom of the air cavity, a heat-resistant layer disposed on the outer wall of the base, lugs secured to the sides of the base, a warning light mounted on the surface of the base, a smoke sensor mounted on the side of the base away from the warning light, a buzzer mounted on the side of the base away from the smoke sensor, an outer cover connected to the inner wall of the base, a screw extending through the lug, a gasket connected to the outer wall of the screw, and a mounting plate connected to the top of the gasket. The fan generates negative pressure, accelerating the air flow rate around the device, enabling the smoke sensor to detect smoke and issue a warning signal as soon as a fire occurs.

[0004] The disadvantages of the above disclosed solution are that: since the alarm needs to be maintained regularly and the device is fixed by screws, it takes a lot of time to install and disassemble the alarm, thereby reducing maintenance efficiency. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a household fire prevention alarm device, in which a clamping space for clamping a clamping column is formed by two clamping blocks. After the clamping column is subjected to force, it can automatically enter or exit the clamping space formed by the two clamping blocks, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a household fire prevention alarm device, comprising a mounting plate, an alarm being detachably provided on one side of the mounting plate, a connecting box being fixedly provided on one side of the alarm, a clamping column being fixedly provided on one side of the connecting box, a mounting frame being fixedly provided on one side of the mounting plate, a connecting plate being fixedly provided in the mounting frame, two symmetrically arranged mounting ears being fixedly provided on the connecting plate, two clamping blocks being rotatably provided between the two mounting ears, the two clamping blocks forming a clamping space for clamping the clamping column, the clamping column and the clamping block being slidably fitted together, a receiving plate being fixedly provided on the top of the clamping block, and a spring being fixedly provided between the receiving plate and the connecting plate.

[0007] Furthermore, the ends of the two clamping blocks away from the connecting plate are both arc-shaped, the clamping column is cylindrical, and the clamping column is slidably engaged with the arc-shaped ends of the two clamping blocks.

[0008] Furthermore, threaded holes are provided at the four corners of the mounting plate.

[0009] Furthermore, the installation frame and the connection box are both rectangular parallelepiped structures, and the connection box is slidably inserted into the installation frame.

[0010] Furthermore, there are two connecting plates, and the two connecting plates are symmetrically arranged.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Because the two clamping blocks form a clamping space for the clamping column, a receiving plate is fixedly installed on the top of the clamping block, and a spring is fixedly installed between the receiving plate and the connecting plate. Therefore, when installing the alarm, the connection box is inserted into the installation frame. The connection box drives the clamping column to slide and cooperate with one end of the two clamping blocks, and drives the two clamping blocks to move away from each other, so that the clamping column can smoothly enter the clamping space formed by the two clamping blocks. Because the two clamping blocks move away from each other and compress the corresponding springs, when the clamping column is fully inserted into the clamping space formed by the two clamping blocks, the restoring force of the spring drives the clamping block to move through the receiving plate, so that the two clamping blocks clamp the clamping column and fix it, thus completing the fixed installation of the alarm. When the alarm needs to be disassembled, it can be pulled out with a certain amount of force. This makes it easier to disassemble and assemble the alarm during maintenance, reduces the time required for disassembly, and improves the efficiency of alarm maintenance.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 4 The present invention provides a technical solution: a household fire prevention alarm device comprising a mounting plate 1 having threaded holes at each of its four corners for securing the mounting plate 1 to a wall via screws engaging the threaded holes. A siren 8 is detachably mounted on one side of the mounting plate 1. A connection box 9 is fixedly mounted on one side of the siren 8. The connection box 9 is a rectangular parallelepiped structure, and a cylindrical clamping post 10 is fixedly mounted on one side of the connection box 9.

[0020] A mounting frame 2 is fixedly mounted on one side of the mounting plate 1. The mounting frame 2 is a hollow rectangular parallelepiped structure with one side open. A connection box 9 is slidably inserted into the mounting frame 2. The dimensions of the mounting frame 2 match those of the connection box 9 to prevent shaking of the connection box 9. Two symmetrically arranged connection plates 3 are fixedly mounted on the side of the mounting frame 2 opposite the opening. The two connection plates 3 are arranged parallel to each other and vertically.

[0021] Two symmetrically arranged mounting ears are fixedly mounted in the middle of the connecting plate 3. A connecting rod 4 is fixedly mounted between the two mounting ears. Two clamping blocks 5 are rotatably mounted on the connecting rod 4. The two clamping blocks 5 are movably engaged with the ends connected to the connecting rod 4 to prevent interference when rotating around the connecting rod 4. The two clamping blocks 5 form a C-shape, thereby forming a clamping space for the clamping column 10. A receiving plate 6 is fixed vertically on the top of the clamping blocks 5, and a spring 7 is fixed between the receiving plate 6 and the connecting plate 3.

[0022] The ends of the two clamping blocks 5 away from the connecting plate 3 are both arc-shaped, and the arc-shaped ends of the two clamping blocks 5 are slidably matched with the clamping column 10 to facilitate the clamping column 10 to enter the clamping space formed by the two clamping blocks 5.

[0023] The working principle of the household fire prevention alarm device provided by the utility model is as follows:

[0024] During use, the mounting plate 1 is fixed to the wall by means of screws and threaded holes, and then the connection box 9 on one side of the alarm 8 is inserted into the mounting frame 2. When the connection box 9 moves into the mounting frame 2, the connection box 9 drives the clamping column 10 to slide with the two clamping blocks 5 away from the end of the connecting plate 3, and drives the two clamping blocks 5 to move away from each other, so that the clamping column 10 smoothly enters the clamping space formed by the two clamping blocks 5. Since the two clamping blocks 5 move away from each other and compress the corresponding spring 7, when the clamping column 10 is completely clamped into the clamping space formed by the two clamping blocks 5, the restoring force of the spring 7 drives the clamping block 5 to move through the receiving plate 6, so that the two clamping blocks 5 clamp the clamping column 10, thereby completing the fixed installation of the alarm 8.

[0025] When it is necessary to disassemble the alarm 8, the alarm 8 can be pulled outwards with a certain force. This can reduce the time for installing or disassembling the alarm 8 and improve the efficiency of the alarm 8 maintenance.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
