These gases are supplied to residential, commercial, and industrial users through pipelines or in containers for various purposes, including cooking, heating, hot water supply, and power generation. It is characterized by its high efficiency, cleanliness, and convenience. Currently, gas is piped to every household. To ensure the safety of gas use, protective devices are typically installed at the valves of the gas pipelines.

[0003] Chinese patent CN217272297U discloses a gas leak protection device. This device, through the setting of an alarm component, will activate a buzzer and warning light to provide information such as gas leak when gas leaks and enters the alarm component. At the same time, the alarm component will control the valve control component, causing the stepper motor to start. With the system cooperation of various components in the valve control component, the control lever is moved, that is, the valve is closed, effectively solving the problems existing in the prior art.

[0004] However, the valve control components in the aforementioned patents are only applicable to long-handled valves, while there are many types of valve handles, such as T-shaped handles, handwheel handles, and butterfly handles. This results in certain limitations in the use of the aforementioned patents. Furthermore, the aforementioned patents are not applicable to pipes of different diameters, which further reduces their scope of application. Utility Model Content

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] Please see Figures 1-4 This utility model provides an adjustable gas safety protection device, including a circular block 100. A rectangular groove 101 is formed on the surface of the circular block 100. A gas leak alarm 111 is installed on the upper surface of the circular block 100, corresponding to the rectangular groove 101. Four clamping rods 102 are installed on the lower side of the circular block 100 via a first clamping mechanism 200, and the four clamping rods 102 are arranged in pairs. An annular groove 103 is formed on the lower surface of the rectangular groove 101. A rotating ring 104 is rotatably installed inside the annular groove 103. A mounting base 106 is installed on the outer side of the rotating ring 104 via a connecting plate 105. Two V-shaped clamping plates 107 are installed on the lower side of the mounting base 106 via a second clamping mechanism 300. An electric push rod 108 is mounted on the upper surface of the mounting base 106. A toothed plate 109 is mounted on the end of the telescopic end of the electric push rod 108. Teeth 110 are provided on the outer surface of the round block 100. The toothed plate 109 and the teeth 110 are engaged and connected.

[0026] In use, firstly, adjust the positions of the two sets of clamping rods 102 using the first clamping mechanism 200, so that the two sets of clamping rods 102 are respectively located on both sides of the valve handle. Then, clamp the two V-shaped clamping plates 107 on both sides of the pipe, and drive the two V-shaped clamping plates 107 closer together using the second clamping mechanism 300, thereby clamping the device onto the pipe. Due to the structural characteristics of the V-shaped clamping plates 107, it can clamp pipes of different diameters, improving its applicability. After the device is fixed to the pipe by the V-shaped clamping plates 107, the first clamping mechanism 200 is used to drive the two sets of clamping rods 102 closer together. The device is brought close to the valve handle and clamped there. When the gas leak alarm 111 detects a gas leak, it can control the electric push rod 108 to start. The telescopic end of the electric push rod 108 drives the toothed plate 109 to move. Since the toothed plate 109 and the teeth 110 mesh with each other, the round block 100 can be rotated. The handle can be turned by the clamping rod 102 to achieve the purpose of closing the valve. Under the drive of the first clamping mechanism 200, the two sets of clamping rods 102 can clamp the outside of the T-shaped handle, handwheel handle and butterfly handle, so that it can be used for valves with different handle types, further improving the applicability of this device.

[0027] Specifically, the first clamping mechanism 200 includes a first threaded rod 201 with a pair of reverse threads rotatably installed inside the rectangular groove 101. Movable plates 202 are installed on both reverse threads of the first threaded rod 201, and four clamping rods 102 are arranged in pairs on the lower side of the two movable plates 202. A sliding groove 203 is opened on the inner wall of the rectangular groove 101. A slider 204 is installed on the side surface of the movable plate 202 and is located in the sliding groove 203. When the first threaded rod 201 is turned, due to the reverse threads and the limiting effect of the sliding groove 203 and the slider 204 on both movable plates 202, the two movable plates 202 can be driven to move closer or further apart under the drive of the threaded connection.

[0028] Specifically, the second clamping mechanism 300 includes a mounting groove 301 formed on the lower surface of the mounting base 106. A second threaded rod 302 with a pair of reverse threads is rotatably connected inside the mounting groove 301, and two V-shaped clamps 107 are respectively mounted on the two reverse threads. A limit rod 303 is installed inside the mounting groove 301, and the V-shaped clamps 107 are slidably mounted on the limit rod 303. When the second threaded rod 302 is turned, since both V-shaped clamps 107 are limited by the limit rod 303, under the action of the reverse threads, the two V-shaped clamps 107 can be driven to move closer or further apart, thereby achieving the purpose of clamping.

[0029] Specifically, the lower surface of the movable plate 202 has two adjustment grooves 400. The clamping rod 102 is damped and slidably installed in the adjustment grooves 400. By setting the adjustment grooves 400, the horizontal position of the clamping rod 102 can be adjusted, thereby changing the distance between the two clamping rods 102 on the same side, thereby further improving the clamping range of the valve handle.

[0030] Specifically, a knob 500 is installed at the end of both the first threaded rod 201 and the second threaded rod 302. The outer surface of the knob 500 is provided with anti-slip texture. The knob 500 and the anti-slip texture make it easy to manually turn the first threaded rod 201 and the second threaded rod 302, and reduce the chance of slipping.

[0031] Specifically, rubber pads are provided on the surfaces of the clamping rod 102 and the V-shaped clamping plate 107. The rubber pads can increase the friction of the surfaces of the clamping rod 102 and the V-shaped clamping plate 107, thereby improving their clamping effect.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
