Description

Technical Field

[0001] This application relates to the technical field of testing gas safety alarm probes, and in particular to a gas alarm probe testing device. Background Technology

[0002] Gas alarms monitor the concentration of gas in the air in real time through built-in sensors. When the concentration reaches a preset threshold, they trigger an audible and visual alarm and can also shut off the gas valve or start ventilation equipment. Modern alarms can be linked with devices such as solenoid valves, exhaust fans, and smart access control systems to automatically cut off the gas supply, ventilate, or remotely notify users (such as through a mobile app).

[0003] Gas safety alarm probes are widely used in residential homes, shopping malls, and other places to detect gas leaks. To improve the effectiveness of gas safety alarm probes, they need to be tested regularly. In practice, alarm probes for industrial and commercial users are often installed at heights of more than 3 meters. Existing detection methods require working at heights or frequently disassembling and reassembling pipelines to sample gas, which is inefficient and prone to causing gas leaks. Therefore, it is necessary to propose a gas alarm probe detection device to solve the above problems. Utility Model Content

[0004] To address the problem that existing detection methods are inefficient and prone to gas leakage risks because industrial and commercial users often install alarm probes at heights of more than 3 meters, requiring work at heights or frequent disassembly and reassembly of pipelines for gas sampling. This application provides a gas alarm probe detection device.

[0005] This application provides a gas alarm detector probe detection device, which adopts the following technical solution: A gas alarm detector probe detection device includes a support plate, a mounting plate fixedly installed on the top of the support plate, an upper rotating cylinder rotatably installed inside the mounting plate, a telescopic rod rotatably connected to the mounting plate at the bottom of the upper rotating cylinder, belts fitted on the outer surfaces of the upper and lower rotating cylinders, gears fixedly installed on the outer surfaces of the upper rotating cylinder on both sides of the belts, a handwheel rotatably connected to the front side of the mounting plate and fixedly connected to the front side of the lower rotating cylinder, a connecting plate slidably installed inside the support plate, a telescopic rod fixedly connected to the top of the connecting plate, a rack fixedly installed on the telescopic rod, the rack meshing with the gears, a gas cylinder fixedly installed on the right side of the support plate, the gas cylinder being connected to the inside of the telescopic rod via a pipe, a limit bracket fixedly installed on the right side of the mounting plate surrounding the telescopic rod, and a handle fixedly installed at the bottom of the support plate.

[0006] By utilizing the interplay of belts, gears, and racks, particularly the meshing of gears and racks, the upper drum rotates via the belt when the handwheel turns, which in turn drives the rack to slide. This causes the telescopic rod to slide upwards relative to the mounting plate, allowing its top to reach the gas alarm probe and deliver gas to the higher probe. This eliminates the need for operators to climb, improving detection efficiency and safety. Furthermore, the adjustable height of the telescopic rod accommodates probes of varying heights, expanding the device's applicability. By retracting the telescopic rod downwards to the right side of the mounting plate, the overall space occupied by the device is reduced, facilitating its storage.

[0007] A further improvement to the technical solution of this application is that a connecting ring is sleeved around the telescopic rod at the top of the limit frame, and a protective cover is fixedly installed on the top of the connecting ring.

[0008] By adopting the above technical solution, the protective cover is set on the periphery of the telescopic rod near the outlet. When the top of the telescopic rod approaches the probe, the protective cover fits against the front of the probe. The protective cover can cover the probe and the periphery of the telescopic rod. During the process of gas flowing out of the telescopic rod opening, the gas that may leak around the probe can be effectively collected, preventing gas diffusion and inaccurate detection, thereby improving the detection effect.

[0009] A further improvement to the technical solution of this application is that a sealing ring is attached to the top of the protective cover.

[0010] By adopting the above technical solution, the sealing ring can increase the tightness of the fit between the protective cover and the outer wall of the probe, further improving the sealing effect and thus improving the detection effect.

[0011] A further improvement of the technical solution of this application is that: a locking block is slidably installed inside the connecting ring by a spring, the locking block and the inside of the telescopic rod are engaged with each other, and a pull block is connected to both the left and right sides of the connecting ring, the inner side of the pull block is fixedly connected to the surface of the locking block.

[0012] By adopting the above technical solution, the spring itself can push the locking block into the interior of the telescopic rod, thereby fixing the connecting ring to the periphery of the telescopic rod. By pulling the locking block outward, the locking block can be separated from the interior of the telescopic rod, so that the protective cover can be removed. This reduces the space occupied compared to the overall structure and makes it convenient to store the telescopic rod and the protective cover separately.

[0013] A further improvement of the technical solution of this application is that: several side plates are fixedly installed on the right side of the mounting plate at the bottom of the limit frame, the side plates are located on the front and rear sides of the telescopic rod, and second balls are rolled on the front and rear inner sides of the side plates, the second balls are in contact with the front and rear surfaces of the telescopic rod.

[0014] By adopting the above technical solution, the telescopic rod can be limited from both the front and rear sides by setting several side plates, ensuring that the telescopic rod moves in a straight line. Furthermore, by setting a second ball bearing, the side plates can be separated from the outer surface of the telescopic rod. During the sliding process of the telescopic rod, the second ball bearing can roll along the surface of the telescopic rod, thereby reducing wear on the telescopic rod and extending the service life of the telescopic rod and the side plates.

[0015] A further improvement of the technical solution of this application is that: a number of first balls are rolled inside the limiting frame, and the first balls are in contact with the outer surface of the telescopic rod.

[0016] By adopting the above technical solution, the first ball bearing inside the limiting frame can separate the limiting frame from the outer surface of the telescopic rod. During the sliding process of the telescopic rod, the first ball bearing can roll along the surface of the telescopic rod, thereby reducing the wear on the telescopic rod and extending the service life of the telescopic rod and the limiting frame.

[0017] A further improvement to the technical solution of this application is that a laser pointer is fixedly installed near the top of the telescopic rod.

[0018] The above technical solution utilizes a laser pointer. As the telescopic rod approaches the probe, the laser pointer emits a laser beam that points directly at the probe, making it easier for the operator to align the telescopic rod with the probe and improve the accuracy of the detection.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides a gas alarm detector detection device. By setting up a belt, gears, racks, and other cooperating structures, the top of the telescopic rod can be brought close to the gas alarm detector during the rotation of the handwheel and the rotating drum, so that the gas is delivered to the high detector. This eliminates the need for operators to climb to heights, improving detection efficiency and safety. Furthermore, by adjusting the height of the telescopic rod, it can accommodate detectors of different heights, expanding the applicability of the device. By retracting the telescopic rod downwards to the right side of the mounting plate, the overall space occupied by the device can be reduced, making it convenient for storage.

[0020] 2. This application provides a gas alarm probe detection device. By setting a protective cover around the telescopic rod near the outlet, the probe and the telescopic rod can be covered. During the process of gas flowing out of the telescopic rod opening, the device can effectively collect any leaked gas around the probe, preventing inaccurate detection caused by gas diffusion, thereby improving the detection effect. Furthermore, the protective cover can be easily installed and removed by a movable pull block. After the protective cover is removed, the space occupied by the device is reduced compared to the overall structure, making it convenient to store the telescopic rod and the protective cover separately.

[0021] 3. This application provides a gas alarm probe detection device. By setting a laser pointer, the laser pointer emits a laser as the telescopic rod approaches the probe, which makes it easier for the operator to align the telescopic rod with the probe, thereby improving the accuracy of the detection.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] Example 1 See Figure 1 , Figure 2 and Figure 4 This application provides a gas alarm detector detection device, including a support plate 1, an mounting plate 2 fixedly installed on the top of the support plate 1, an upper rotating cylinder 14 rotatably installed inside the mounting plate 2, a telescopic rod 3 rotatably connected inside the mounting plate 2 at the bottom of the upper rotating cylinder 14, a belt 7 sleeved on the outer surface of the upper rotating cylinder 14 and the lower rotating cylinder 13, gears 5 fixedly installed on the outer surface of the upper rotating cylinder 14 on both sides of the belt 7, a handwheel 8 rotatably connected to the front side of the mounting plate 2, the handwheel 8 being fixedly connected to the front side of the lower rotating cylinder 13, a connecting plate 12 slidably installed inside the support plate 1, a telescopic rod 3 fixedly connected to the top of the connecting plate 12, a rack 6 fixedly installed on the outer side of the telescopic rod 3, the rack 6 meshing with the gear 5, a gas cylinder 4 fixedly installed on the right side of the support plate 1, the gas cylinder 4 being connected to the inside of the telescopic rod 3 through a pipe, a limit bracket 11 fixedly installed on the right side of the mounting plate 2 around the telescopic rod 3, and a handle 10 fixedly installed at the bottom of the support plate 1.

[0026] In this embodiment, through the interplay of structures such as belt 7, gear 5, and rack 6, with gear 5 and rack 6 meshing together, as handwheel 8 rotates the lower rotating drum 13, belt 7 drives the upper rotating drum 14 to rotate. Gear 5 then drives rack 6 to slide, causing telescopic rod 3 to slide upwards relative to mounting plate 2. This allows the top of telescopic rod 3 to approach the gas alarm probe, delivering gas to the higher probe, eliminating the need for operators to climb, thus improving detection efficiency and safety. Furthermore, adjusting the height of telescopic rod 3 accommodates probes of different heights, expanding the device's applicability. Retracting telescopic rod 3 downwards to the right side of mounting plate 2 reduces the overall space occupied by the device, facilitating its storage.

[0027] Example 2 See Figure 1 and Figure 3 Based on Embodiment 1, this application provides a technical solution: Preferably, a connecting ring 17 is sleeved around the telescopic rod 3 at the top of the limiting frame 11, and a protective cover 9 is fixedly installed on the top of the connecting ring 17; a sealing ring 16 is attached to the top of the protective cover 9; a locking block 18 is slidably installed inside the connecting ring 17 through a spring 19, and the locking block 18 is engaged with the inside of the telescopic rod 3; pull blocks 20 are connected to both the left and right sides of the connecting ring 17, and the inner side of the pull block 20 is fixedly connected to the surface of the locking block 18.

[0028] In this embodiment, by placing the protective cover 9 on the periphery of the telescopic rod 3 near the outlet, when the top of the telescopic rod 3 approaches the probe, the protective cover 9 fits against the front of the probe. This allows the protective cover 9 to cover the probe and the periphery of the telescopic rod 3, effectively collecting any leaked gas around the probe during the flow of gas from the opening of the telescopic rod 3, preventing inaccurate detection due to gas diffusion, and thus improving the detection effect. The sealing ring 16 increases the tightness of the fit between the protective cover 9 and the outer wall of the probe, further improving the sealing effect and thus enhancing the detection performance. The spring 19's own elasticity pushes the locking block 18 into the telescopic rod 3, thereby fixing the connecting ring 17 to the periphery of the telescopic rod 3. Pulling the pull block 20 outwards separates the locking block 18 from the inside of the telescopic rod 3, facilitating the removal of the protective cover 9. This reduces the space occupied compared to the overall structure, making it convenient to store the telescopic rod 3 and the protective cover 9 separately.

[0029] Example 3 See Figure 1 , Figure 2 and Figure 4Based on Embodiment 2, this application provides a technical solution: Preferably, a plurality of side plates 21 are fixedly installed on the right side of the mounting plate 2 at the bottom of the limiting frame 11. The side plates 21 are located on the front and rear sides of the telescopic rod 3. Second ball bearings 22 are rolled on the front and rear inner sides of the side plates 21, and the second ball bearings 22 are in contact with the front and rear side surfaces of the telescopic rod 3. A plurality of first ball bearings 15 are rolled inside the limiting frame 11, and the first ball bearings 15 are in contact with the outer surface of the telescopic rod 3. A laser pointer 23 is fixedly installed near the top of the telescopic rod 3.

[0030] In this embodiment, by setting several side plates 21, the telescopic rod 3 can be limited from both the front and rear sides, ensuring that the telescopic rod 3 maintains linear movement. Furthermore, by setting second ball bearings 22, the side plates 21 can be separated from the outer surface of the telescopic rod 3. During the sliding process of the telescopic rod 3, the second ball bearings 22 can roll along the surface of the telescopic rod 3, thereby reducing wear on the telescopic rod 3 and extending the service life of the telescopic rod 3 and the side plates 21. Similarly, by setting first ball bearings 15 inside the limiting frame 11, the limiting frame 11 can be separated from the outer surface of the telescopic rod 3. During the sliding process of the telescopic rod 3, the first ball bearings 15 can roll along the surface of the telescopic rod 3, thereby reducing wear on the telescopic rod 3 and extending the service life of the telescopic rod 3 and the limiting frame 11. By setting a laser pointer 23, as the telescopic rod 3 approaches the probe, the laser pointer 23 can emit a laser beam that points in a straight line towards the probe, making it easier for the operator to align the telescopic rod 3 and bring it close to the probe, thus improving the accuracy of the detection.

[0031] The working principle of this gas alarm probe detection device is explained in detail below.

[0032] like Figures 1-4 As shown, the operator turns on the laser pointer 23, holds the handle 10 with one hand, and turns the handwheel 8 with the other, which in turn drives the lower rotating drum 13 to rotate, causing the belt 7 to drive the upper rotating drum 14 to rotate. At the same time, the gear 5 drives the rack 6 to slide upward, bringing the telescopic rod 3 closer to the probe. The laser emitted by the laser pointer 23 is then aimed at the probe. Finally, the protective cover 9 is placed over the probe, ensuring that the sealing ring 16 is in contact with the wall. The valve of the gas cylinder 4 is then opened, allowing gas to enter the telescopic rod 3 through the pipe and flow to the probe for testing. After the test is completed, the operator can turn the handwheel 8 in the opposite direction, so that the telescopic rod 3 is on the right side of the mounting plate 2, and then pull the pull block 20 outward, separating the locking block 18 from the inside of the telescopic rod 3. The protective cover 9 can then be removed from the outside of the telescopic rod 3 for storage.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
