Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gas hose testing equipment, specifically a gas hose safety performance testing device. Background Technology
[0002] Gas hoses are important components connecting gas appliances and gas pipelines. Their safety performance is directly related to the safety of gas use in homes and industries. During the production process of gas hoses, specialized equipment is required to test the safety performance of the hoses to ensure that they can be put into use.
[0003] For example, patent CN217716812U discloses a leak detection device for metal hoses, including a base. Rotating the handle drives the adjusting screw to rotate, which in turn drives the coupling to rotate. The rotation of the coupling drives the left adjusting screw to rotate, and the rotation of the two adjusting screws drives the adjusting sleeve to move left and right respectively. The displacement of the adjusting sleeve drives the displacement of the connecting plate and the connecting pipe, and at the same time, the flange and the water pipe to move. At this time, the flange is tightly fitted to the metal hose body. The flange is fixed to the metal hose body with screws, which facilitates the detection of metal hoses of different lengths, achieving the advantage of convenient detection. The above case mainly focuses on leak detection of metal hoses when detecting hoses, but it is not applicable to the monitoring of gas hoses. Furthermore, judging its sealing performance by the color-changing layer is not accurate because the color-changing layer may be affected by environmental factors, such as humidity and temperature changes. For minor leaks, the color-changing layer may not react obviously.
[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing gas hose safety performance testing devices. Utility Model Content
[0005] The purpose of this utility model is to provide a gas hose safety performance testing device to solve the problems mentioned in the background art, which mainly focuses on leak detection of metal hoses when testing hoses, but is not applicable to the monitoring of gas hoses. Furthermore, the color-changing layer is used to judge its sealing performance, but the color-changing layer may be affected by environmental factors, such as changes in humidity and temperature, resulting in inaccurate color changes. For minor leaks, the color-changing layer may not show obvious results.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas hose safety performance testing device, comprising a workbench, a fixed plate disposed below the workbench, a water tank disposed on the top of the fixed plate, a first bracket mounted on one side of the top of the workbench, and a second bracket slidably connected to the other side of the top of the workbench; a pressure pump mounted on the top of the first bracket, the outlet end of the pressure pump being connected to a gas pipe, a hose connector being mounted on one end of the gas pipe, and a pressure gauge disposed on the top of the hose connector; and a testing mechanism for testing the airtightness of the gas hose being disposed on the workbench.
[0007] Furthermore, the detection mechanism includes a drive motor, which is mounted on the bottom of a fixed plate via a support plate. A threaded rod is rotatably connected to one side of the top of the fixed plate, and a guide rod is fixedly connected to the other side of the top of the fixed plate. The output end of the drive motor is fixedly connected to the threaded rod. Threaded blocks are provided on both sides of the water tank. The threaded block on one side is threadedly connected to the threaded rod, and the threaded block on the other side is slidably connected to the outer wall of the guide rod.
[0008] Furthermore, a gear is fixedly connected to the outer wall of the top of the threaded rod, and racks mesh on both sides of the gear. The two racks are arranged opposite to each other. Sliding plates are slidably connected to both sides inside the workbench. One rack is connected to the sliding plate on one side through a connecting strip, and the other rack is connected to the sliding plate on the other side through a fixing strip.
[0009] Furthermore, the second bracket is provided with a clamping mechanism for clamping the gas hose. The clamping mechanism includes an electric push rod, the output end of which is equipped with a connecting plate. Movable plates are fixedly connected to both sides of the connecting plate, and connecting rods are rotatably connected to both ends of both sides of the movable plates.
[0010] Furthermore, irregularly shaped strips are rotatably connected to both sides of the bottom of the second bracket, the middle part of the irregularly shaped strips is rotatably connected to one end of the connecting rod, and a clamping block is installed at the bottom of the irregularly shaped strips.
[0011] Furthermore, the worktable is internally rotatably connected to a reciprocating lead screw, and the interior of the second bracket is threadedly connected to the outer wall of the reciprocating lead screw.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This gas hose safety performance testing device first connects the gas hose to the hose connector. A pressure pump then fills the hose with gas, and a pressure gauge monitors the pressure in real time, allowing operators to accurately monitor internal pressure changes and providing a stable and accurate data foundation for subsequent airtightness testing. When adjusting the position of the second support, rotating the reciprocating screw utilizes the threaded engagement to move the second support linearly along the screw, ensuring a tight connection between the gas hose and the connector. This effectively prevents gas leakage, guarantees the stability of the testing environment, and ensures the reliability of the data obtained during the testing process. This, in turn, guarantees the accuracy of the final test results, allowing testing personnel to make correct judgments about the quality of the gas hose based on precise data.
[0014] Furthermore, after the drive motor starts, its output end drives the threaded rod to rotate. Through the cooperation of the threaded block and the threaded rod, as well as the guiding action of the guide rod, the water tank reciprocates up and down. At the same time, the gear at the top of the threaded rod rotates, driving the meshing racks on both sides to move in opposite directions, thereby causing the sliding plate fixedly connected to the racks to move in opposite directions synchronously, completing the water tank ejection action.
[0015] Furthermore, after the electric push rod is activated, its telescopic movement, through the linkage of components such as the connecting plate, moving plate, connecting rod, and shaped strip, enables the clamping block to clamp or release the gas hose. The close and orderly linkage between the components reduces the complexity and error of manual operation, making the entire testing process smooth and efficient, saving a significant amount of time and labor costs, and improving the overall efficiency of the testing work.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: Please refer to Figure 1 , Figure 3 and Figure 4 This utility model provides the following technical solution: a gas hose safety performance testing device, including a workbench 1, a fixed plate 2 below the workbench 1, a water tank 3 on the top of the fixed plate 2, a first bracket 4 installed on one side of the top of the workbench 1, and a second bracket 6 slidably connected to the other side of the top of the workbench 1; a pressure pump 5 is installed on the top of the first bracket 4, the outlet end of the pressure pump 5 is connected to a gas pipe 8, a hose connection port 9 is installed at one end of the gas pipe 8, and a pressure gauge 10 is installed on the top of the hose connection port 9; a testing mechanism for testing the airtightness of the gas hose is provided on the workbench 1; the testing mechanism includes a drive motor 17, which is installed on the bottom of the fixed plate 2 via a support plate. A threaded rod 18 is rotatably connected to one side of the top of the fixed plate 2, and a guide rod 19 is fixedly connected to the other side of the top of the fixed plate 2. The output end of the drive motor 17 is fixedly connected to the threaded rod 18. Threaded blocks 20 are provided on both sides of the water tank 3. One threaded block 20 is threadedly connected to the threaded rod 18, and the other threaded block 20 is slidably connected to the outer wall of the guide rod 19. A gear 22 is fixedly connected to the outer wall of the top of the threaded rod 18. Two racks 23 are meshed on both sides of the gear 22 and are arranged opposite to each other. Sliding plates 21 are slidably connected to both sides inside the workbench 1. One rack 23 is connected to the sliding plate 21 on one side through a connecting strip, and the other rack 23 is connected to the sliding plate 21 on the other side through a fixing strip.
[0025] When using the detection device, one end of the gas hose needs to be connected to hose connector 9 first. After connection, if... Figure 1 and Figure 2As shown, by turning on pressure pump 5, gas is injected into the gas hose, and then pressure gauge 10 can monitor the pressure inside the hose in real time. Figure 1 and Figure 3 As shown, the drive motor 17 is then started. When the drive motor 17 starts, its output end drives the threaded rod 18 to rotate, as shown. Figure 2 As shown, since threaded blocks 20 are provided on both sides of the water tank 3, one threaded block 20 is threadedly connected to the threaded rod 18, and the other threaded block 20 is slidably connected to the outer wall of the guide rod 19. Therefore, when the threaded rod 18 rotates, as... Figure 2 and Figure 3 As shown, since the threaded block 20 is threadedly engaged with the threaded rod 18, the threaded block 20, which is threadedly connected to the threaded rod 18, will move linearly along the threaded rod 18. Simultaneously, under the guidance of the guide rod 19, the water tank 3 can only perform reciprocating up-and-down motion. Figure 3 As shown, since a gear 22 is fixedly connected to the outer wall of the top of the threaded rod 18, and racks 23 mesh with both sides of the gear 22, with the two racks 23 facing each other, when the threaded rod 18 rotates, the threaded rod 18 will drive the gear 22 fixedly connected to it to rotate synchronously, and the gear 22 will drive the two racks 23 meshing with it on both sides to move in opposite directions, as shown. Figure 3 As shown, the two racks 23 are fixedly connected to the two sliding plates 21. Therefore, the two racks 23 will drive the two sliding plates 21 to move synchronously in opposite directions, so that the two sliding plates 21 slide into the interior of the workbench 1, thereby facilitating the ejection of the water tank 3, so that the water tank 3 can come into contact with the gas hose, and the gas hose can be fully immersed in the water. The airtightness of the gas hose can be judged by observing whether there are bubbles in the water.
[0026] Example 2: Please refer to Figure 5 and Figure 6 Based on Embodiment 1, a clamping mechanism is also disclosed, the specific structure of which is as follows:
[0027] The clamping mechanism includes an electric push rod 7, with a connecting plate 12 installed at the output end of the electric push rod 7. Movable plates 11 are fixedly connected to both sides of the connecting plate 12, and connecting rods 13 are rotatably connected to both ends of both sides of the movable plates 11. Shaped strips 14 are rotatably connected to both sides of the bottom of the second bracket 6. The middle part of the shaped strips 14 is rotatably connected to one end of the connecting rods 13, and a clamping block 15 is installed at the bottom of the shaped strips 14. A reciprocating screw 16 is rotatably connected inside the worktable 1, and the inside of the second bracket 6 is threadedly connected to the outer wall of the reciprocating screw 16.
[0028] When securing the gas hose, such as Figure 5 and Figure 6As shown, by activating the electric actuator 7, since the output end of the electric actuator 7 is equipped with a connecting plate 12, the extension and retraction of its output end will drive the connecting plate 12 to move linearly, such as... Figure 5 and Figure 6 As shown, since the connecting plate 12 is fixedly connected to both sides of the movable plate 11, and both ends of the movable plate 11 are rotatably connected to the connecting rod 13, when the connecting plate 12 moves up and down, it will synchronously drive the movable plate 11 to move up and down, as shown. Figure 5 and Figure 6 As shown, since the bottom of the second bracket 6 is rotatably connected to both sides of the irregular strip 14, and the middle part of the irregular strip 14 is rotatably connected to one end of the connecting rod 13, after the moving plate 11 moves, the moving plate 11 will drive the irregular strip 14 to rotate around its rotational connection point with the second bracket 6 through the connecting rod 13, as shown. Figure 5 and Figure 6 As shown, a clamping block 15 is installed at the bottom of the irregular strip 14. Therefore, when the irregular strip 14 rotates, the clamping block 15 will move accordingly, realizing the clamping or releasing action of the gas hose, so as to fix the gas hose for testing. Figure 5 As shown, since the reciprocating screw 16 is rotatably connected inside the workbench 1, and the internal thread of the second bracket 6 is connected to the outer wall of the reciprocating screw 16, when the reciprocating screw 16 is rotated, the second bracket 6 will move linearly along the reciprocating screw 16 due to the thread engagement. The position of the second bracket 6 can be adjusted to tightly connect the gas hose and the hose connection port 9, avoiding gas leakage that could cause inaccurate test results. In actual use, the first gear 12 needs to rotate one revolution, and the two racks need to move a distance of multiple meshing teeth in opposite directions to ensure that when the sliding plate 21 is completely moved into the interior of the base 1, the water tank 3 can be smoothly ejected.
