Description

Technical Field

[0001] This utility model relates to the field of valve core airtightness testing technology, and in particular to a valve core airtightness testing device. Background Technology

[0002] The valve core is a valve component that enables basic functions such as directional control, pressure control, or flow control through its movement. It is the core component of the valve body and achieves directional control (such as switching between hot and cold water), pressure regulation (such as stabilizing water flow pressure), and flow control (such as adjusting the water flow). In faucets, the valve core is called the "heart" component, which determines the sensitivity of the switch, the sealing performance, and the durability.

[0003] Currently, the airtightness of the valve core directly affects the valve's performance and safety. If the valve core's sealing performance is substandard, it may lead to gas or liquid leakage, which not only affects the normal use of the product but may also cause safety accidents. Airtightness testing of the valve core can prevent media leakage, reduce resource waste and environmental pollution. Therefore, during the valve core manufacturing process, it is necessary to perform airtightness testing on the valve core using valve core airtightness testing equipment.

[0004] In existing technologies, when testing the airtightness of valve cores, the valve core is placed in a lower mold, and then the upper mold is closed to create a sealed space. Gas is then supplied, and pressure changes are observed to determine if the valve core is airtight. After testing, the tested valve core needs to be removed, and a new valve core needs to be placed in for testing, resulting in low efficiency. Therefore, we propose a valve core airtightness testing device. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. Example

[0027] Please see Figures 1-6 A valve core airtightness testing device includes a body 1, with multiple sets of fixed frames 2 fixedly connected to the body 1. A telescopic rod 3 is fixedly connected to the fixed frame 2, and a connecting plate 4 is fixedly connected to the telescopic end of the telescopic rod 3. An upper mold 5 is fixedly connected to the connecting plate 4. A support block 6 installed directly below the upper mold 5 is also fixedly connected to the bottom end of the fixed frame 2. A rotating plate 7 is rotatably connected to the support block 6. Multiple sets of lower molds 8 are fixedly connected to the rotating plate 7, one set of lower molds 8 being correspondingly arranged with the upper mold 5. A sealing ring 9 is installed at the bottom end of the upper mold 5 and the end of the lower mold 8. A rotating component 10 installed inside the body 1 is connected to the bottom end of the rotating plate 7.

[0028] It should be noted that a threaded post 24 is provided at the end of the drive shaft 17, and the threaded post 24 passes through the rotating plate 7. A threaded block 25 is also threadedly connected to the threaded post 24, thereby fixing the rotating plate 7 between the threaded block 25 and the drive shaft 17. By turning the threaded block 25, the threaded block 25 is moved away from the threaded post 24, which facilitates the disassembly and installation of the rotating plate 7, thereby facilitating the maintenance and replacement of the lower mold 8.

[0029] In addition, a limiting rod 26 is fixedly connected to the connecting plate 4, and the limiting rod 26 is slidably connected to the fixed frame 2. Thus, the stability of the movement of the connecting plate 4 is improved by setting the limiting rod 26, so that the upper mold 5 and the lower mold 8 can be stably closed.

[0030] The machine body 1 has heat dissipation holes 29, which can improve the heat dissipation of the internal electrical components of the machine body 1 and extend the service life of the equipment.

[0031] In the embodiments of this utility model, please refer to Figure 4 and Figure 5The rotating component 10 includes a rotating shaft 11 that is fixedly connected to multiple sets of rotating plates 7. A limiting component 15 connected to the machine body 1 is installed on the outer side of the rotating shaft 11. The rotating shaft 11 is rotatably connected to the machine body 1. A spur gear 12 is fixedly connected to the rotating shaft 11. A gear belt 13 meshes with the outer side of the spur gear 12. A driving component 14 is installed at the end of one set of rotating shafts 11 to facilitate the rotation of the rotating plates 7 and realize the switching between multiple sets of lower molds 8.

[0032] After the valve core is inspected, the control drive 14 is started. The drive 14 causes the rotating shaft 11 to rotate, which in turn causes the rotating plate 7 to rotate through the action of the rotating shaft 11, the threaded column 24, and the threaded block 25. The rotation of the rotating plate 7 causes the lower mold 8 to rotate and switch, rotating the inspected valve core to one side of the fixed frame 2 and rotating the valve core to be inspected to the end position of the support block 6. At this time, the valve core is inspected again. Thus, during the inspection process, there is no need to repeatedly pick up and put down the valve core, improving the inspection efficiency.

[0033] It should be noted that in this solution, the driving component 14 includes a motor 16 fixed inside the body 1. The output end of the motor 16 is fixedly connected to a drive shaft 17. The drive shaft 17 is fixedly connected to the rotating shaft 11, which facilitates providing a stable driving force for the rotation of the rotating plate 7. During switching, the motor 16 is started, so that the motor 16 can drive the drive shaft 17 to rotate, and the rotation of the drive shaft 17 causes the rotating shaft 11 to rotate.

[0034] In addition, a limiting member 15 is provided on the outer side of the rotating shaft 11, thereby limiting the rotation of the rotating shaft 11 through the action of the limiting member 15. Thus, the rotating shaft 11 will not rotate arbitrarily when no external force is applied to it, thereby improving the stability of the rotating plate 7 and preventing the rotating plate 7 from rotating arbitrarily after the switching is completed, which would cause the lower mold 8 and the upper mold 5 to not correspond.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The limiting component 15 includes rotating blocks 18 that are fixed to the outer sides of multiple sets of rotating shafts 11. The outer side of the rotating block 18 is fitted with a fixed sleeve 19 that is fixedly connected to the machine body 1. A spring 20 is fixedly connected inside the rotating block 18. A sliding column 21 is fixedly connected to the output end of the spring 20. A ball 22 is rotatably connected to the end of the sliding column 21. A groove 23 that matches the ball 22 is provided on the fixed sleeve 19. There are multiple sets of grooves 23 arranged in a circular pattern, which facilitates limiting the rotation of the rotating shaft 11, thereby improving the stability after the lower mold 8 is switched.

[0036] The ball bearings 22 and the grooves 23 are configured in multiple sets arranged in a circular pattern. During the rotation of the rotating shaft 11, the rotating block 18 is driven to rotate, which in turn causes the ball bearings 22 to rotate. During the rotation of the rotating block 18, the ball bearings 22 can always be in a corresponding state with the multiple sets of circumferentially arranged grooves 23, thereby limiting the rotation of the rotating block 18 and the rotating shaft 11.

[0037] During implementation, when testing the valve core, multiple sets of valve cores are placed in the lower mold 8. Then, the telescopic rod 3 is activated, which causes the connecting plate 4 to move the upper mold 5 downward, thereby closing the upper mold 5 and the lower mold 8. The valve core is then tested by the operation of the machine body 1. After the test is completed, the telescopic rod 3 retracts, causing the upper mold 5 and the lower mold 8 to separate. After the upper mold 5 moves upward, the motor 16 starts, which drives the drive shaft 17 to rotate. The rotation of the drive shaft 17 causes the rotating shaft 11 to rotate, which in turn causes the rotating plate 7 to rotate through the action of the rotating shaft 11, the threaded column 24, and the threaded block 25. The rotation of the rotating plate 7 causes the lower mold 8 to rotate and switch, rotating the tested valve core to one side of the fixed frame 2 and rotating the valve core to be tested to the end position of the support block 6. At this time, the valve core is tested again. Thus, during the test, there is no need to repeatedly pick up and put down the valve core, improving the testing efficiency.

[0038] The roller grooves 23 are arranged in multiple sets in a circular pattern. During the rotation of the rotating shaft 11, the rotating block 18 is driven to rotate, which in turn causes the ball bearings 22 to rotate. During the rotation of the rotating block 18, the ball bearings 22 can always be in a corresponding state with the multiple sets of circumferentially arranged roller grooves 23, thereby limiting the rotation of the rotating block 18 and the rotating shaft 11. Thus, the rotating shaft 11 will not rotate arbitrarily without the application of external force, thereby improving the stability of the rotating plate 7 and preventing the rotating plate 7 from rotating arbitrarily after the switching is completed, which would cause the lower mold 8 and the upper mold 5 to not correspond.
