Technical Field

[0001] This utility model relates to the field of combustible gas alarm installation technology, specifically to a combustible gas alarm installation device. Background Art

[0002] A combustible gas alarm installation device is a device for the fixed installation of combustible gas alarms. It is commonly used in laboratories and other places to detect gas leaks and to issue timely alarms to prevent major accidents.

[0003] However, existing combustible gas alarm installation devices still suffer from problems such as limited installation options, inconvenient installation and difficulty in relocation, and difficulty in disassembling and assembling the alarm. For example, Chinese utility model patent CN213177374U discloses a fixed gas alarm installation device, which suffers from poor applicability of the mounting bracket and inability to be quickly disassembled and assembled. Therefore, we propose a combustible gas alarm installation device to solve the aforementioned problems. Utility Model Content

A mounting frame is installed on the front side of the support rod. A back plate is installed on the rear end of the upper surface of the mounting frame. Limiting rods are installed on both the left and right sides of the mounting frame.

[0007] The gas alarm body is placed in the middle of the mounting bracket. Fixing slots are provided on both the left and right sides of the gas alarm body. A rotating shaft is installed inside the fixing slot. A detection port is connected to the lower end of the gas alarm body. An ear plate is installed at the rear end of the upper surface of the gas alarm body. A positioning hole is provided inside the ear plate.

[0008] The throttle is installed on the rear side of the gas alarm body, and the surface of the throttle is covered with an anti-slip sleeve. A toothed disc is fixedly installed on the front side of the throttle, and a toothed belt is installed on the right side of the toothed disc. A movable plate is fixedly installed on the upper end of the toothed belt.

[0009] Preferably, the mounting bracket forms an up-and-down sliding structure with the gas alarm body via a throttle and a sliding groove.

[0010] Preferably, the toothed disc and the toothed belt are connected by a meshing connection.

[0011] Preferably, the limiting rod forms an engaging structure with the fixing groove on the side of the gas alarm body via a rotating shaft.

[0012] Preferably, the movable plate slides up and down inside the support rod via a toothed belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the combustible gas alarm installation device;

[0014] 1. An adjustable mounting bracket is provided, with a throttle installed on the rear side of the support rod. The throttle facilitates the rotation of the gear plate, which engages with the toothed belt. The toothed belt moves up and down accordingly, making it easy to adjust the height of the mounting bracket. This allows it to adapt to gas detection at different heights, making it convenient and practical. The support rod and mounting bracket are integrated into one device, facilitating the relocation of the gas alarm.

[0015] 2. Limiting rods and fixing slots are set. Limiting rods are installed on both the left and right sides of the mounting frame. By rotating the limiting rods, the limiting rods can be easily rotated into the fixing slots on the left and right sides of the gas alarm, which can play the role of limiting the gas alarm.

[0016] 3. The gas alarm is equipped with a lug plate on the back. The lug plate has a positioning hole inside. When the limiting rod is damaged and not repaired in time, screws can be used to align with the positioning hole of the lug plate to fix the gas alarm on the back plate. Multiple fixing methods make it convenient to install and remove the gas alarm. Attached Figure Description

[0022] 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.

[0023] See also Figure 1-4 This utility model provides a technical solution: a combustible gas alarm installation device, including a support base 1, a support rod 2, a mounting frame 3, a gas alarm body 4, a detection port 5, a back plate 6, an ear plate 7, a positioning hole 8, a handle 9, a gear plate 10, a gear belt 11, a moving plate 12, a support rod 13, a rotating shaft 14, a limiting rod 15, a sliding groove 16, a fixing groove 17, and an anti-slip sleeve 18. Figure 2 and Figure 3 As shown, a support rod 2 is installed on the upper surface of the support base 1. The support base 1 supports and stabilizes the support rod 2. A sliding groove 16 is opened on the front side of the support rod 2. A support rod 13 is installed inside the sliding groove 16. A mounting bracket 3 is fixedly installed on the front side of the support rod 13. The gas alarm body 4 is placed on the upper surface of the mounting bracket 3. A detection port 5 is connected to the bottom end of the gas alarm body 4. The middle of the mounting bracket 3 is hollow, and the detection port 5 at the bottom end of the gas alarm body 4 is exposed, which is convenient for gas detection. The support base 1, the support rod 2 and the mounting bracket 3 constitute an integrated device, which is convenient for movement.

[0024] The mounting bracket 3 has grooves on both the left and right sides. A rotating shaft 14 is installed inside the grooves. A limiting rod 15 is installed in the middle of the surface of the rotating shaft 14. The gas alarm body 4 has fixing slots 17 on both the left and right sides. After the gas alarm body 4 is placed on the mounting bracket 3, the position of the fixing slot 17 is aligned with the position of the limiting rod 15. The limiting rod 15 is rotated to the inside of the fixing slot 17 to limit the gas alarm body 4. The limiting rod 15 is rotated from the inside of the fixing slot 17 to the outside, and the gas alarm body 4 is disassembled.

[0025] When the limiting rod 15 is damaged and not repaired in time, a back plate 6 is installed on the back side of the mounting bracket 3, and an ear plate 7 is installed on the back side of the gas alarm body 4. The ear plate 7 has a positioning hole 8 inside. The screw is passed through the positioning hole 8 to fix the gas alarm body 4 on the back plate 6. The gas alarm body 4 is fixedly installed. When it is necessary to disassemble the gas alarm body 4, the screw is unscrewed and the gas alarm body 4 is disassembled.

[0026] like Figure 1 and Figure 4As shown, a handle 9 is installed on the rear side of the support rod 2. An anti-slip sleeve 18 is installed on the surface of the handle 9 to prevent hand slippage. A gear plate 10 is fixedly installed on the front side of the handle 9. A toothed belt 11 is meshed and connected to the right side of the gear plate 10. A movable plate 12 is fixedly installed at the upper end of the toothed belt 11. A support rod 13 is connected to the front side of the movable plate 12. A mounting bracket 3 is fixedly installed on the front side of the support rod 13. The gas alarm body 4 is fixed on the mounting bracket 3. When the detected gas is lighter than air, the height of the gas alarm body 4 needs to be increased. Rotate the handle 9. The handle 9 drives the gear plate 10 to rotate, and the toothed belt 11 moves up and down accordingly, thus adjusting the height of the gas alarm body 4. When the height of the gas alarm body 4 needs to be decreased, rotate the handle 9 in the opposite direction. The height adjustment is then completed. After the handle 9 has been rotated, tighten the screw on the front side of the handle 9 to fix the handle 9.
