Description

Technical Field

[0001] This utility model relates to the field of gas alarm technology, specifically to a portable miniature gas alarm. Background Technology

[0002] A gas alarm is a safety device specifically designed for real-time monitoring of the concentration of specific gases in the environment. When the gas concentration exceeds a preset safety threshold, it will immediately trigger an alarm signal. These devices are widely used in key areas such as industrial production, public safety, and environmental protection. Their core objective is to prevent explosions caused by flammable gas leaks or poisoning and asphyxiation caused by toxic gas leaks, resulting in personal injury and property damage.

[0003] Chinese utility model patent CN219267090U discloses a fixed combustible gas alarm installation device. By setting a reset spring, the position of the limiting seat can be moved. When installing the combustible gas detector body, the detector can be pressed down by using the inclined surface of the limiting seat, so that the limiting groove and the limiting seat can be engaged, thus quickly completing the installation of the combustible gas detector body. At the same time, the position of the extension cylinder can be adjusted by adjusting the adjusting rod. By rotating the adjusting rod, multiple limiting seats can be pulled at the same time, thereby separating the limiting seats from the limiting groove, thus completing the disassembly of the combustible gas detector body.

[0004] Existing gas alarms are bulky, often causing inconvenience for users in actual use. They are difficult to securely place near the user during work, making it impossible to detect the surrounding gas environment in a timely manner, thus affecting work safety and efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a portable miniature gas alarm to solve the problem that existing gas alarms are too large to be carried around.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable miniature gas alarm, comprising a gas alarm body;

[0007] A clamping mechanism is embedded in the middle of one side of the outer wall of the gas alarm body, and anti-collision mechanisms are installed at the four corners of the outer wall of the gas alarm body.

[0008] The clamping mechanism includes a clamping seat, an adjusting cavity, a limiting frame, a clamping plate, and springs. The clamping seat is embedded in the middle of the outer wall of the gas alarm body. The adjusting cavity is opened on the upper side inside the clamping seat. The limiting frame is movably inserted into the middle of the inner wall of one side of the adjusting cavity. The clamping plate is inserted through the other end of the limiting frame. Multiple springs are provided, and all multiple springs are installed between the inner wall of the adjusting cavity and the inner wall of the limiting frame.

[0009] Furthermore, the clamping mechanism also includes a positioning groove, a first magnetic plate, and a second magnetic plate. The positioning groove is formed in the middle of the inner side of the clamping plate, the first magnetic plate is embedded in the middle of the inner wall of the positioning groove, and the second magnetic plate is installed in the middle of the outer wall of the clamping seat.

[0010] Furthermore, the anti-collision mechanism includes an anti-collision sleeve, a buffer block, a mounting groove, and a buffer. The buffer block is installed between the inner walls of both sides of the anti-collision sleeve. The mounting groove is opened at one corner of the outer wall of the buffer block. The buffer block is installed at one corner of the outer wall of the gas alarm body through the mounting groove. There are two buffers, and the two buffers are respectively installed on the inner walls of both sides of the anti-collision sleeve. The other ends of the two buffers are respectively installed at the top and left ends of the gas alarm body.

[0011] Furthermore, anti-collision pads are installed at both ends of the gas alarm body, a hook is installed on one side of the top of the gas alarm body, a hanging rope is installed on the other side of the top of the gas alarm body, three warning lights are provided on the upper part of the outer wall of the other side of the gas alarm body, and a switch button is provided on the lower part of the outer wall of the other side of the gas alarm body.

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] Example 1:

[0027] This utility model provides a portable miniature gas alarm, including a gas alarm body 1;

[0028] A clamping mechanism 2 is embedded in the middle of the outer wall of one side of the gas alarm body 1. The gas alarm body 1 is the core component of the entire portable miniature gas alarm. It carries the main functions of gas detection and alarm. In the existing technology, the gas alarm body 1 usually includes conventional components such as gas sensor, signal processing circuit, and alarm device. Anti-collision mechanisms 3 are installed at the four corners of the outer wall of the gas alarm body 1.

[0029] The clamping mechanism 2 includes a clamping seat 21, an adjusting cavity 22, a limiting frame 23, a clamping plate 24, and springs 25. The clamping seat 21 is embedded in the middle of the outer wall of the gas alarm body 1. The adjusting cavity 22 is opened on the upper side inside the clamping seat 21. The adjusting cavity 22 provides space for the movement of the limiting frame 23. The limiting frame 23 is movably inserted into the middle of the inner wall of one side of the adjusting cavity 22. The clamping plate 24 is inserted into the other end of the limiting frame 23. The clamping plate 24 is used to clamp external objects. Multiple springs 25 are provided, and multiple springs 25 are installed between the inner wall of the adjusting cavity 22 and the inner wall of the limiting frame 23.

[0030] The clamping mechanism 2 also includes a positioning groove 26, a first magnetic plate 27, and a second magnetic plate 28. The positioning groove 26 is opened in the middle of the inner side of the clamping plate 24. The first magnetic plate 27 is embedded in the middle of the inner wall of the positioning groove 26. The second magnetic plate 28 is installed in the middle of the outer wall of the clamping seat 21.

[0031] A hook 5 is installed on one side of the top of the gas alarm body 1. The hook 5 is usually made of metal and has a certain strength and toughness. It is fixed to one side of the top of the gas alarm body 1 by bolts or welding. A hanging rope 6 is installed on the other side of the top of the gas alarm body 1. The hanging rope 6 can be a nylon rope or other high-strength rope. Users can hang the gas alarm around their neck or fix it to other objects through the hanging rope 6 for easy carrying and use.

[0032] The second magnetic plate 28 has opposite magnetic poles to the first magnetic plate 27. This design allows the first magnetic plate 27 and the second magnetic plate 28 to attract each other when the clamping plate 24 approaches the clamping seat 21, further enhancing the stability of the clamping. The second magnetic plate 28 is engaged with the positioning groove 26. The limiting frame 23 is set with an I-shaped structure. This structure can ensure that the limiting frame 23 slides stably in the adjustment cavity 22, while limiting its sliding range and preventing the limiting frame 23 from coming out of the adjustment cavity 22.

[0033] Working Principle: During use, the gas alarm body 1, as the core component, undertakes the gas detection task. The gas alarm body 1 is small in size, making it easy for users to carry. When the user needs to secure the device, the clamping plate 24 is pulled outwards. At this time, the limiting frame 23 slides within the adjusting cavity 22 and compresses the spring 25, creating an adjustable opening between the clamping plate 24 and the clamping seat 21. After clamping the device in a pocket, belt, or other position, the restoring force of the spring 25 pushes the limiting frame 23 back, causing the clamping plate 24 and the clamping seat 21 to fit tightly against the surface of the clamped object. The spring 25 allows the clamping plate 24 to automatically adjust its position according to the thickness of the clamped object, ensuring a tight and stable clamping. This design avoids the problem of the device falling off due to vibration or movement. At the same time, the second magnetic plate 28 is inserted into the positioning slot 26 for snap-fit ​​positioning, and the attraction between the opposite magnetic poles of the second magnetic plate 28 and the first magnetic plate 27 forms a secondary fixation, which further enhances the reliability of clamping and prevents the device from accidentally slipping off during use. This greatly improves the convenience and safety of carrying. Furthermore, the magnetism of the first magnetic plate 27 can attract the gas alarm body 1 to the surface of a metal object for gas detection. With the cooperation of the top hook 5 and the hanging rope 6, users can choose to clamp, hang, or hold the gas alarm body 1 according to the scenario, meeting the diverse needs of hand-held or worn, and significantly improving portability and operational flexibility.

[0034] Example 2:

[0035] This embodiment is basically the same as the previous embodiment, except that the anti-collision mechanism 3 includes an anti-collision sleeve 31, a buffer block 32, a mounting groove 33, and a buffer 34. The buffer block 32 is installed between the inner walls of both sides of the anti-collision sleeve 31. The material of the buffer block 32 is selected from foam plastic or rubber with a certain degree of elasticity, which can absorb some energy during a collision. The mounting groove 33 is opened at one corner of the outer wall of the buffer block 32. The shape of the mounting groove 33 is adapted to the shape of one corner of the outer wall of the gas alarm body 1 to ensure the stability of the installation. The buffer block 32 is installed on the gas alarm body 1 through the mounting groove 33. Two buffers 34 are provided on one corner of the outer wall of the body 1. The two buffers 34 are respectively installed on the inner walls of the two sides of the anti-collision sleeve 31. The other ends of the two buffers 34 are respectively installed on the top and left ends of the gas alarm body 1. The buffers 34 are made of polyurethane buffers. The polyurethane buffers have a microporous bubble structure inside. Each micropore is equivalent to a small spring. When the equipment is hit by an external force or dropped, these micropores convert the impact kinetic energy into deformation potential energy through compression deformation. At the same time, the organic polymer chains inside the material generate heat through friction during the deformation process, further consuming energy.

[0036] Both ends of the gas alarm body 1 are equipped with anti-collision pads 4. Three warning lights 7 are provided on the upper part of the outer wall of the other side of the gas alarm body 1. The three warning lights 7 are LED lights of different colors, such as red, yellow and green, to indicate different alarm states. A switch button 8 is provided on the lower part of the outer wall of the other side of the gas alarm body 1. The switch button 8 is used to control the gas alarm to be turned on and off.

[0037] The outer wall of the anti-collision pad 4 is designed with an arc-shaped structure. This shape can better adapt to the force situation when the human body comes into contact with or collides with other objects, reducing local stress concentration. The anti-collision sleeve 31 is designed with an L-shaped structure. This shape can better fit the four corners of the outer wall of the gas alarm body 1, providing more comprehensive protection. The L-shaped anti-collision sleeve 31 can effectively disperse the collision force and reduce damage to the gas alarm body 1. Both the anti-collision sleeve 31 and the anti-collision pad 4 are made of rubber. Rubber has good elasticity and wear resistance, which can play a buffering and protective role in the event of a collision.

[0038] Working principle: When the equipment is subjected to external impact or drop, the L-shaped anti-collision sleeves 31 installed at the four corners of the outer wall serve as the first line of defense. Their rubber material absorbs part of the impact energy through elastic deformation. At the same time, the buffer block 32 and the buffer 34 form a double buffer structure. The buffer 34 further disperses the impact force at the top and left end through compression deformation, effectively reducing the damage of vibration to internal components. In addition, the arc-shaped anti-collision pad 4 can effectively disperse the impact force on the side of the gas alarm body 1, avoiding local stress concentration that could lead to shell breakage. Through the coordinated work of the anti-collision mechanism 3 and the anti-collision pad 4, the impact resistance of the equipment in complex environments is significantly improved, which not only extends the service life of the equipment but also reduces maintenance costs, ensuring the reliable operation of the gas alarm in various harsh environments.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
