Description

Technical Field

[0001] This utility model relates to the field of gas detection and alarm technology, specifically a pressure detection alarm for gas leaks. Background Technology

[0002] Gas leak pressure detection alarms, often referred to as "gas leak detectors" or "gas leak alarms," ​​are used to monitor the concentration of specific gases (such as natural gas, methane, carbon monoxide, etc.) in the surrounding environment. When a gas leak is detected, these devices will sound an alarm to alert people to the potential danger. These alarms are widely used in homes, industries, and commercial settings to ensure people's safety.

[0003] A search revealed publication number CN218446912U, which discloses an online monitoring type toxic and harmful gas detector alarm, belonging to the field of alarm technology. The alarm includes an alarm body with multiple buffer components connected to its outer periphery. These buffer components are further connected to a fixing component, and the fixing component is connected to a reinforcing component. The fixing component includes a connecting frame, a connecting plate, and a blocking plate. Two connecting frames are arranged side-by-side, and multiple connecting plates corresponding to the buffer components connect between the two frames. One connecting frame is rotatably connected to the blocking plate via a damping shaft. A transparent protective plate is connected to the side of the connecting frame away from the blocking plate, and side support plates are connected to three sides of the connecting frame. The side support plates have circular through holes for fixing bolts to pass through. This online monitoring type toxic and harmful gas detector alarm not only meets different usage needs but also buffers and enhances airflow.

[0004] In summary, in the prior art CN218446912U, the alarm body is fixed to the load-bearing structure using fixing components. Gas leak pressure detection alarms should typically be installed close to the ground. To facilitate monitoring of gas leaks and timely alarm issuance, the detector should be close to the area where leaks may occur. However, in locations with limited operating space, the fixing components in the prior art CN218446912U cannot assist operators in adjusting the position of the alarm body, making installation inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide a pressure detection alarm for gas leaks, which has the advantages of making it easy for staff to adjust the height of the alarm body and reducing the difficulty of operation in narrow spaces, thus solving the problem of the troublesome operation of installing pressure detection alarms in narrow spaces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure detection alarm for gas leaks, comprising a screw sleeve, a fixing plate, and a clamping plate. A bearing is embedded in the fixing plate, and a lead screw is fixedly mounted on the inner ring of the bearing. The screw sleeve engages with the lead screw. A retainer is mounted on the rear side of the screw sleeve, and screw holes are provided on both sides of the retainer. Screws are threaded into the inner walls of the two screw holes. Bearings are mounted on opposite sides of the two clamping plates. The opposite ends of the two screws are fixedly connected to the inner rings of the two bearings. The detection alarm body is clamped and fixed on opposite sides of the two clamping plates.

[0007] When using a pressure detection alarm for gas leaks according to this technical solution, the mounting bracket is fixed to the load-bearing structure using bolts or other tools through the fixing holes of the mounting bracket. The power cord is inserted into the power connector to provide power to the detector body. At the required height, the screw is rotated using a handwheel, and the screw sleeve moves on the rotating screw. The screw sleeve drives the detector body to descend through the retainer. After the detector body is adjusted to a suitable height, air enters the detector body through the expansion mask, and the air that has completed the detection inside the detector body is discharged from the exhaust pipe.

[0008] Preferably, a handwheel is mounted on the top of the lead screw, and the handwheel is parallel to the fixed plate. The lead screw can be rotated using the handwheel.

[0009] Preferably, sliding rods are welded to both sides of the bottom of the fixing plates on both sides of the bearing, and sliding sleeves are installed on both sides of the detection alarm body. The two sliding sleeves are slidably connected to the two sliding rods. The sliding rods limit the movement of the detection alarm body. When the detection alarm body is raised or lowered, it moves on the two sliding rods through the two sliding sleeves to prevent the detection alarm body from shaking.

[0010] Preferably, a baffle is installed at the bottom of each of the two slide rods. The two baffles prevent the two sliding sleeves from slipping off the two slide rods.

[0011] Preferably, a second baffle is installed at the bottom of the lead screw. The second baffle prevents the threaded sleeve from slipping off the lead screw.

[0012] Preferably, a fixing frame is welded to the front side of the fixing plate, and the fixing frame has symmetrical fixing holes. The fixing frame is fixed to the load-bearing structure through the fixing holes using bolts or other tools.

[0013] Preferably, each of the two screws has a handle mounted on one of its opposite ends. The two screws can be rotated using the two handles.

[0014] Preferably, each of the two clamping plates is equipped with a slider on its front side, and a groove is formed on the inner side of the retainer. The two sliders are slidably connected to the groove. The two sliders limit the movement of the two clamping plates, and when the two clamping plates move, the two sliders slide within the groove to prevent the two clamping plates from shaking.

[0015] Preferably, a power connector is embedded in the top of the detection alarm body, an air outlet pipe is embedded in the side of the detection alarm body, and an expansion mask is embedded in the bottom of the detection alarm body. The power cord is inserted into the power connector to provide power to the detection alarm body, air enters the detection alarm body through the expansion mask, and the air inside the detection alarm body after detection is completed is discharged through the air outlet pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a screw sleeve and a retainer to fix the detector body inside the retainer. By rotating the screw with a handwheel, the screw sleeve moves on the rotating screw. The screw sleeve drives the detector body to descend through the retainer, adjusting the detector body to a suitable detection height. This achieves the effect of making it convenient for staff to adjust the height of the detector body and reducing the difficulty of operation in narrow spaces. Attached Figure Description
