Description

Technical Field

[0001] This utility model relates to the field of alarm connection technology, and in particular to a wall-mounted connection device for combustible gas alarms. Background Technology

[0002] A combustible gas detection alarm device is a device used to detect the content of combustible gas in the air in real time and to sound an alarm when the content of combustible gas in the air reaches a specified value.

[0003] Most alarms are fixed to the wall by drilling holes during installation, which requires tools to disassemble them for maintenance and repeated drilling during installation, affecting the aesthetics of the wall. Therefore, a wall-mounted connection device for combustible gas alarms is proposed to solve this problem. Utility Model Content

An installation groove is provided inside the fixing post and at one end near the bottom. An elastic pushing member is disposed in the installation groove. The bottom of the elastic pushing member penetrates the fixing post and extends to the outside of the fixing post.

[0008] As an improvement to the above technical solution, the elastic pusher includes a piston slidably disposed in the mounting groove, a movable rod fixedly disposed at the bottom of the piston, and a spring disposed between the top of the piston and the top of the inner wall of the mounting groove.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The wall-mounted connection device for combustible gas detectors includes:

[0019] An alarm 10 is fixedly connected to the top of the alarm 10. A slot 111 is opened on the inner wall of the connecting cylinder 11 along the axial direction of the connecting cylinder 11. A limiting groove 112 is opened on the inner wall of the connecting cylinder 11, which is perpendicular to the bottom of the slot 111 and communicates with the slot 111.

[0020] The connecting assembly includes a fixing plate 20, a fixing post 21 fixedly disposed at the bottom of the fixing plate 20 and adapted to the connecting cylinder 11, and a locking post 22 integrally formed on the side wall of the fixing post 21. An installation groove 23 is provided inside the fixing post 21 and near the bottom. An elastic pushing member is provided in the installation groove 23. The bottom of the elastic pushing member passes through the fixing post 21 and extends to the outside of the fixing post 21.

[0021] Specifically, first, fix the fixing plate 20 in the connecting assembly to the preset installation position on the wall using fasteners such as bolts and expansion screws, ensuring that the fixing plate 20 is tightly and securely attached to the wall without any looseness. At this time, the fixing post 21 fixed at the bottom of the fixing plate 20 is in a vertically downward state, and the elastic pusher in the mounting groove 23 inside the fixing post 21 is in an initially relaxed state. The bottom of the elastic pusher extends through the fixing post 21 to the outside, maintaining a pressable movable state. Hold the alarm 10 and align the connecting tube 11 fixedly connected to its top with the fixing post 21, so that the opening of the connecting tube 11 faces the fixing post 21. At the same time, adjust the angle of the alarm 10 to ensure that the locking post 22 can be aligned with the slot 111 on the inner wall of the connecting tube 11. Slowly push the alarm 10 so that the fixing post 21 is gradually inserted into the connecting post 21. Inside the connecting tube 11, during this process, the locking pin 22 will slide along the slot 111 on the inner wall of the connecting tube 11. Since the slot 111 is an axially opened channel structure, it can provide a stable sliding guide for the locking pin 22. When the locking pin 22 slides to the bottom of the slot 111 with the fixing pin 21, the alarm 10 is rotated, causing the alarm to drive the connecting tube 11 to rotate, so that the locking pin 22 enters the limiting groove 112. The limiting groove 112 will form an upper and lower limit on the locking pin 22. The alarm 10 is fixed to the wall through the stable connection between the connecting tube 11 and the connecting component. The installation and fixing process is completed. During the insertion process, the elastic pushing member at the bottom of the fixing pin 21 will first contact the inner bottom surface of the connecting tube 11. As it continues to press down, the elastic pushing member is compressed to provide reset power for subsequent disassembly.

[0022] When disassembly is required, hold the main body of the alarm 10 and slowly rotate it in the opposite direction to the installation direction. This will cause the connecting cylinder 11 to rotate synchronously in the opposite direction. As the connecting cylinder 11 rotates, the limiting groove 112 gradually disengages from the locking pin 22 until the locking pin 22 is completely removed from the limiting groove 112 and returns to its initial position at the bottom of the slot 111. The upper and lower limiting effect of the limiting groove 112 on the locking pin 22 is released. After the locking pin 22 returns to the slot 111, the previously compressed elastic pushing member loses the indirect constraint of the limiting groove 112 and begins to release the stored elastic potential energy, generating a pushing force on the fixed pin 21. This pushing force acts directly on the inner bottom surface of the connecting cylinder 11, pushing the connecting cylinder 11... Moving downwards along the axis of the fixed column 21, the alarm 10 does not need to be pulled with additional force. Under the pushing force of the elastic pusher, the connecting cylinder 11 will naturally move the alarm 10 downwards. The locking pin 22 on the side wall of the fixed column 21 will then slide down along the slot 111. With the restoring elastic force of the elastic pusher, the downward distance of the connecting cylinder 11 gradually increases, and the fixed column 21 is gradually pulled out from the inside of the connecting cylinder 11. When the elastic pusher is fully restored to its initial state, the fixed column 21 has mostly disengaged from the connecting cylinder 11. At this time, simply pull down the alarm 10 gently to make the locking pin 22 slide completely out of the slot 111, and the alarm 10 is successfully removed from the wall.

[0023] In one embodiment, the elastic pusher includes a piston 28 slidably disposed in the mounting groove 23, a movable rod 25 fixedly disposed at the bottom of the piston 28, and a spring 24 disposed between the top of the piston 28 and the top of the inner wall of the mounting groove 23. In the initial state, the bottom of the movable rod 25 is located outside the fixed post 21. When installed, as the alarm 10 moves continuously, the bottom surface of the connecting cylinder 11 first contacts the movable rod 25 and pushes the movable rod 25 to move upward. The movable rod 25 drives the piston 28 at the top to slide upward along the inner wall of the mounting groove 23. The piston 28 compresses the spring 24 at the top, causing the spring 24 to gradually contract and deform, storing elastic potential energy.

[0024] In one embodiment, the bottom of the fixing column 21 has multiple sets of mounting grooves 23 and adsorption holes 26 communicating with the outside. When the piston 28 slides up, the volume of the space below the mounting groove 23 increases, the air pressure decreases, and negative pressure is generated. When the bottom of the fixing column 21 contacts the bottom of the inner wall of the connecting cylinder 11, the fixing column 21 adsorbs the inner bottom surface of the connecting cylinder 11 through the adsorption holes 26 to assist in fixing.

[0025] In one embodiment, a sealing ring 27 is embedded in the bottom of the fixing column 21 through a groove. The sealing ring 27 continuously and tightly fits the inner bottom surface of the connecting cylinder 11 and the bottom of the fixing column 21, maintaining the negative pressure state at the bottom of the mounting groove 23. The negative pressure adsorption force and the mechanical locking structure provide dual protection for the installation stability of the device, and the installation process is officially completed.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
