Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, specifically to an airtightness testing device for a braided hose connector. Background Technology

[0002] Water pipe hoses are components used to connect water pipes. Currently, the assembly and airtightness testing of water pipe hose joints are mostly done manually in steps. Manual operation is labor-intensive, has low testing efficiency, and cannot guarantee quality, thus resulting in high production costs.

[0003] Chinese Patent No. CN214538415U discloses an airtightness testing device for braided hose connectors. The above solution is used to test the airtightness of braided hose connectors.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the above solutions have low stability in the joint connection process during actual use, which leads to air pressure leakage at the connection point and a decrease in the accuracy of airtightness testing.

[0005] This invention proposes an airtightness testing device for braided hose connectors to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to improve the docking performance of the device during docking testing by combining the docking structure and the joint structure, thereby ensuring the connection stability at the docking point and avoiding inaccurate air tightness testing due to air pressure leakage at the docking point, thus overcoming the problems mentioned in the background art.

[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0008] An airtightness testing device for a braided hose connector includes a base, a housing connected to the top of the base, a cover plate connected to the top of the housing, a control module connected to the top of the cover plate, a testing component inside the housing, a docking component connected through the side of the housing, and a connector component docked to the docking component.

[0009] Further defining the above technical solution, the detection component includes a pressure sensor connected to the inner wall side of the housing, an electric telescopic rod connected to the bottom of the inner wall of the housing, a pneumatic cavity connected to the telescopic end of the electric telescopic rod, a pneumatic plate connected to the telescopic end of the electric telescopic rod, the pneumatic plate being slidably connected to the inner wall of the pneumatic cavity, and a connecting pipe being connected through the other end of the pneumatic cavity. By combining the pneumatic cavity with the pneumatic plate structure at the telescopic end of the electric telescopic rod, accurate air pressure control can be achieved, thereby detecting the airtightness of the mating joint under different air pressure environments.

[0010] Further defining the above technical solution, the docking component includes a docking groove that penetrates and connects to the outer side of the housing. The docking grooves are symmetrically distributed on both sides of the outer side of the housing. One docking groove is connected to the pressure sensor, and the other docking groove is connected to the connecting pipe. The pressure sensor can detect the air pressure, and by comparing the air pressure generated by the sliding and squeezing of the air pressure plate driven by the electric telescopic rod, it can be determined whether there is an air pressure leak.

[0011] Further defining the above technical solution, the inner arc surface of the docking groove is provided with a sealing groove, and the outer side of the housing is symmetrically provided with fixed brackets on both sides of the docking groove. A limit rod is connected to the side of the fixed bracket away from the outer side of the housing. The combination of the limit rod and the hook connector can ensure that the docking joint and the docking groove are in tight contact, thereby ensuring that no air pressure leakage occurs at the docking point.

[0012] Further defining the above technical solution, the joint component includes a mating joint that is connected to the mating groove. The outer arc surface of the mating joint is provided with a plurality of sealing protrusions that are equally spaced along the axial direction of the mating joint. The sealing protrusions contact and press with the sealing groove. The combination of the sealing protrusions and the sealing groove can achieve a stable sealing connection at the mating point.

[0013] Further defining the above technical solution, the docking joint is connected by two connecting shells. A rotating bracket is connected to the outer side of the connecting shell near the docking joint. The rotating bracket is rotatably connected to a swinging component. A through sliding groove is provided at the center of the swinging component. The docking is stable and accurate through the structure of the swinging component and the elastic sliding hook.

[0014] Further defining the above technical solution, the swing member is slidably connected to a blocking member on its side, and a sliding spring member is provided on the side of the blocking member. The sliding spring member is slidably connected to the inner wall of the sliding groove, and a spring is connected to the side of the sliding spring member. The other end of the spring is connected to one end of the side of the inner wall of the sliding groove. The spring can elastically pull the docking joint to squeeze into the docking groove.

[0015] Further defining the above technical solution, the sliding spring is connected to a sliding member at one end away from the blocking member, and a swing bracket is provided on the other side of the sliding member. The swing bracket is rotatably connected to a hook member. A magnetic docking member is provided on the outer side of the connecting housing. A magnetic guide member is provided on the side of the swing member close to the connecting housing. The magnetic guide member contacts the magnetic docking member. A handle is connected to the end of the swing member away from the rotating bracket. A connecting pipe is connected through the end of the connecting housing away from the docking joint. The magnetic structure can ensure that the swing member is magnetically fixed.

Figures 1-4 As shown, it includes a base 1, a housing 2 connected to the top of the base 1, a cover plate 3 connected to the top of the housing 2, a control module 4 connected to the top of the cover plate 3, a detection component 5 inside the housing 2, a docking component 7 connected through the side of the housing 2, and a connector component 6 docking with the docking component 7.

[0028] The detection component 5 includes a pressure sensor 501 connected to the inner wall side of the housing 2, an electric telescopic rod 502 connected to the bottom of the inner wall of the housing 2, a pneumatic chamber 503 connected to the telescopic end of the electric telescopic rod 502, a pneumatic plate connected to the telescopic end of the electric telescopic rod 502, the pneumatic plate being slidably connected to the inner wall of the pneumatic chamber 503, and a connecting pipe 504 being connected through the other end of the pneumatic chamber 503. The control module 4 is controlled and connected to the electric telescopic rod 502, and is communicatively connected to the pressure sensor 501. The structure of the control module 4 can reduce the difficulty of using and operating this device.

[0029] The docking component 7 includes a docking groove 701 that penetrates and connects to the outer side of the housing 2. The docking grooves 701 are symmetrically distributed on both sides of the outer side of the housing 2. One docking groove 701 is connected to the pressure sensor 501, and the other docking groove 701 is connected to the connecting pipe 504. The inner arc surface of the docking groove 701 is provided with a sealing groove 702. The outer side of the housing 2 is symmetrically provided with fixing brackets 703 on both sides of the docking grooves 701. The side of the fixing bracket 703 away from the outer side of the housing 2 is connected to a limiting rod 704. The limiting rod 704 facilitates the hooking of the hooking component 614, thereby ensuring that the docking joint 601 can be stably docked.

[0030] The connector component 6 includes a docking connector 601 that is connected to the docking groove 701. The outer arc surface of the docking connector 601 is provided with a plurality of sealing protrusions 602 that are equally spaced along the axial direction of the docking connector 601. The sealing protrusions 602 contact and press with the sealing groove 702.

[0031] The mating joint 601 is connected by two connecting shells 603. A rotating bracket 604 is connected to the outer side of the connecting shell 603 near the mating joint 601. A swinging component 605 is rotatably connected to the rotating bracket 604. A through sliding groove 606 is provided at the center of the swinging component 605.

[0032] The specific working principle is as follows: This device can detect the airtightness of the mating joint 601, thereby ensuring the accuracy of the airtightness detection. Compared with traditional devices, this device can ensure the stability of the sealing at the mating joint, thus ensuring the accuracy of the airtightness detection.

[0033] Example 2: This example provides an airtightness testing device for braided hose connectors, such as... Figures 1-4As shown, a blocking member 607 is slidably connected to the side of the swing member 605. A sliding spring is provided on the side of the blocking member 607. The sliding spring is slidably connected to the inner wall of the sliding groove 606. A spring 609 is connected to the side of the sliding spring. The other end of the spring 609 is connected to one end of the inner wall of the sliding groove 606. A sliding member 608 is connected to the end of the sliding spring away from the blocking member 607. A swing bracket is provided on the other side of the sliding member 608. A hook member 614 is rotatably connected to the swing bracket. A magnetic docking member 611 is provided on the outer side of the connecting shell 603. A magnetic guide member 612 is provided on the side of the swing member 605 near the connecting shell 603. The magnetic guide member 612 contacts the magnetic docking member 611. A handle 610 is connected to the end of the swing member 605 away from the rotating bracket 604. A connecting pipe 613 is connected through the end of the connecting shell 603 away from the docking joint 601.

[0034] The specific working principle is as follows: This device can effectively improve the accuracy of the airtightness detection and processing of the mating joint 601. When this device is used, the mating joint 601 and the mating groove 701 are combined and connected to achieve the effect of detecting the sealing performance of the mating joint 601 and the mating pipe 613.

[0035] During docking, the swinging member 605 is rotated so that the hooking member 614 is close to the limiting rod 704. After the hooking member 614 is connected to the limiting rod 704, the swinging member 605 is rotated so that it is close to the magnetic docking member 611. When the swinging member 605 rotates, the spring 609 is stretched by the sliding spring, so that the docking joint 601 and the docking groove 701 are elastically squeezed against each other. When the magnetic docking member 611 contacts the magnetic conductor 612, the current rotation angle of the swinging member 605 is locked by magnetic attraction, thereby achieving a fixing effect.

[0036] After the connection is fixed, the electric telescopic rod 502 drives the pneumatic plate to slide, thereby generating air pressure. The pressure sensor 501 can detect the air pressure at the other end of the connecting pipe 613 and compare it with the air pressure generated by the pneumatic plate. If the two are the same, it indicates that the airtightness is stable.

[0037] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
