Description

Technical Field

[0001] This utility model relates to the field of gas safety technology, specifically a gas safety use device. Background Technology

[0002] Combustible gas is a flammable gas. Inhaling too much of it can cause poisoning, harm health, and even death. Gas alarm devices are needed for the safe use of gas. These devices are used to detect leaks of flammable gas. When there is a flammable gas leak in an industrial environment, the gas alarm device will issue an alarm signal when it detects that the gas concentration has reached the explosion threshold, so as to remind on-site personnel to take safety measures and thus ensure safety.

[0003] However, the existing device has a single installation method and is not convenient to select different installation methods according to different installation environments, which makes the device less practical.

[0004] Chinese patent discloses a gas safety device (authorization announcement number CN221463546U). When in use, the gas alarm body detects and alarms the gas safety. The mounting plate of the gas alarm body can be fixed or clamped during installation using auxiliary components. The appropriate installation method can be selected according to different installation environments, so that the device can meet more installation needs and has strong practicality.

[0005] However, it has certain drawbacks: the two mounting plates are clamped and installed by the elastic force of the spring. First, relying solely on the elastic force of the spring is not stable enough, and the gas alarm is prone to slipping off the outside of the cylindrical structure. Second, the spring specifications are fixed, which makes it impossible to firmly fix the two mounting plates to the outside of the cylindrical structure with a smaller diameter. When facing a cylindrical structure with a larger diameter, the spring is easily stretched and deformed, losing its original elasticity and affecting the clamping effect. Utility Model Content

[0006] The purpose of this invention is to provide a gas safety device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A gas safety device includes a gas alarm body. The front surface of the gas alarm body has a display screen, and a gas probe is fixedly connected to the lower end of the gas alarm body. An alarm light is fixedly connected to the right end of the gas alarm body. A fixing mechanism is provided on the rear surface of the gas alarm body. The fixing mechanism includes a C-shaped plate, and a threaded rod is movably connected to the left side surface of the C-shaped plate. Fixing members are provided on both the left and right sides of the threaded rod.

[0009] As a further embodiment of this utility model: the fixing member includes a connecting plate, a connecting rod is rotatably connected to the rear end of the connecting plate, a clamping plate is fixedly connected to the outer surface of the connecting rod on the inner side of the connecting plate, a connecting hole is opened at the end of the clamping plate away from the connecting rod, a ratchet is fixedly connected to the outer side of the connecting rod above the connecting plate, and a limiting member is provided on the upper surface of the connecting plate in front of the connecting rod.

[0010] As a further embodiment of this utility model: the limiting member includes a spring, the front end of the spring is fixedly connected to a limiting block, and the rear end of the spring is fixedly connected to a pawl, with a limiting rod rotatably connected to one end of the pawl.

[0011] As a further embodiment of this utility model: the front end of the C-shaped plate is fixed to the rear surface of the gas alarm body, and the right end of the threaded rod is rotatably connected to the inner right side surface of the C-shaped plate.

[0012] As a further embodiment of this utility model: the front end of the connecting plate is slidably connected to the C-shaped plate, and the threaded rod is threadedly connected to the connecting plate.

[0013] As a further improvement of this utility model: the pawl is attached to the ratchet, and the lower ends of the limiting block and the limiting rod are both fixed to the upper surface of the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model features a fixing mechanism. The two clamping plates in the fixing mechanism are initially parallel to the threaded rod. By passing bolts through the connecting holes, the entire device can be fixed to a wall or other location. Rotating the left clamping plate clockwise and the right clamping plate counterclockwise rotates both clamping plates until they are perpendicular to the threaded rod. Rotating the threaded rod causes the two connecting plates to move closer together, so that the two clamping plates are firmly clamped to the outside of the cylindrical structure. This firmly fixes the entire device to the outside of the cylindrical structure, eliminating the need to drill holes in the wall or other locations for installation. Attached Figure Description

[0021] Please see Figure 1 In this embodiment of the utility model, a gas safety device includes a gas alarm body 1, a display screen 2 is provided on the front surface of the gas alarm body 1, a gas probe 3 is fixedly connected to the lower end of the gas alarm body 1, and an alarm light 4 is fixedly connected to the right end of the gas alarm body 1.

[0022] The main body 1 of the gas alarm is the core of the entire device. It integrates various electronic components and sensors to detect and monitor gas leaks. When a gas leak is detected, the main body 1 of the gas alarm will trigger the alarm mechanism to remind the user to take safety measures.

[0023] Display screen 2 is used to display information such as the working status of the gas alarm and the detected gas concentration. Through the display screen, users can intuitively understand the real-time status of the gas alarm and whether there is a risk of gas leakage.

[0024] Gas probe 3 is responsible for detecting and sensing gas leaks. Once a gas leak is detected, gas probe 3 will immediately transmit a signal to the main body 1 of the gas alarm to trigger the alarm mechanism.

[0025] Alarm light 4 is used to provide a visual alarm in case of a gas leak.

[0026] exist Figures 1-4In the middle section: A fixing mechanism 5 is provided on the rear surface of the gas alarm body 1. The fixing mechanism 5 includes a C-shaped plate 6. The front end of the C-shaped plate 6 is fixed to the rear surface of the gas alarm body 1. A threaded rod 7 is movably connected through the left side surface of the C-shaped plate 6. The right end of the threaded rod 7 is rotatably connected to the inner right side surface of the C-shaped plate 6. Fixing members 8 are provided on both the left and right sides of the threaded rod 7. The fixing member 8 includes a connecting plate 9. The front end of the connecting plate 9 is slidably connected to the C-shaped plate 6. The threaded rod 7 is threadedly connected through the connecting plate 9. A connecting rod 10 is rotatably connected to the rear end of the connecting plate 9. The outer surface of the connecting rod 10 is... A clamping plate 11 is fixedly connected to the inner side of the connecting plate 9. A connecting hole 12 is opened at the end of the clamping plate 11 away from the connecting rod 10. A ratchet 13 is fixedly connected to the outside of the connecting rod 10 above the connecting plate 9. A limiting member 14 is provided on the upper surface of the connecting plate 9 in front of the connecting rod 10. The limiting member 14 includes a spring 15. A limiting block 16 is fixedly connected to the front end of the spring 15, and a pawl 17 is fixedly connected to the rear end of the spring 15. The pawl 17 is attached to the ratchet 13. A limiting rod 18 is rotatably connected to one end of the pawl 17. The lower ends of the limiting block 16 and the limiting rod 18 are both fixedly connected to the upper surface of the connecting plate 9.

[0027] The clamping plate 11 is initially parallel to the threaded rod 7, and the connecting hole 12 passes through the bolt, which can fix the entire device at the installation position;

[0028] The left and right ratchet 13s face opposite directions, as do the left and right pawl 17s; that is, the left clamping plate 11 can be rotated normally clockwise, but not counterclockwise; the right clamping plate 11 can be rotated normally counterclockwise, but not clockwise. This allows the two clamping plates 11 to be clamped on the outside of the cylindrical structure after rotating to a position perpendicular to the threaded rod 7; the opposite surfaces of the two clamping plates 11 are both angular surfaces.

[0029] The threads of the two connecting plates 9 are opposite, that is, rotating the threaded rod 7 can drive the two connecting plates 9 to move relative to or in opposite directions, so that the two clamping plates 11 can clamp the outside of cylindrical structures of different diameters.

[0030] After pulling the pawl 17 away from the ratchet 13, the left clamp 11 can be rotated counterclockwise and the right clamp 11 can be rotated clockwise.

[0031] The working principle of this utility model is as follows: When in use, the user passes the bolt through the connecting hole 12 and fixes the entire device to the wall or other location with the bolt; the user can also rotate the left clamping plate 11 clockwise and the right clamping plate 11 counterclockwise, so that the two clamping plates 11 are perpendicular to the threaded rod 7. Then the two clamping plates 11 are placed on the outside of the cylindrical structure, and the threaded rod 7 is rotated to drive the two connecting plates 9 to move closer, so that the two clamping plates 11 are firmly clamped on the outside of the cylindrical structure, thereby fixing the entire device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
