[0002] In recent years, with the revision and improvement of relevant regulations, pressure test connectors have been widely used in automotive chassis braking systems.
[0003] The pressure testing connectors currently in use cannot be directly connected to nylon tubes. They require an adapter to connect to a quick-connect fitting before connecting to the nylon tube, which is cumbersome to install, requires high installation precision, and results in poor gas sealing performance.
[0004] As disclosed in Chinese Patent CN213840011U, a novel quick-connect integrated pressure test connector includes a quick-connect fitting assembly, a threaded base, a connector base, a spring, an O-ring, and a gas sampling rod. The spring, O-ring, and gas sampling rod are installed in the connector base to extract gas. The connector base and quick-connect fitting assembly are press-fitted together to facilitate gas connection. The threaded base and quick-connect fitting assembly are press-fitted together to fix the connection to the mounting end.
[0005] The aforementioned device lacks effective sealing at the connector component mounting joints, which may lead to leakage and affect the pressure test results. Furthermore, the component connections are not reinforced, potentially causing loosening.
[0006] To address these issues, a novel quick-connect integrated pressure test connector is proposed. Utility Model Content
[0007] The purpose of this utility model is to provide a novel quick-connect integrated pressure test connector in order to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0009] A novel quick-connect integrated pressure test connector includes a base and a connecting hole. The connecting hole extends through the middle of the upper part of the outer surface of the base, and a fixing tube is fixedly connected to the inner wall of the connecting hole. A threaded head mounting assembly is provided on the upper part of the outer surface of the fixing tube. A quick-connect connector integrated mounting assembly is provided at one end of the base, and a connector base mounting assembly is provided at the other end of the base.
[0010] Furthermore, the threaded head mounting assembly includes a first sealing cylinder fixedly mounted on the upper part of the outer surface of the fixed tube, a first sleeve movably mounted on the outer surface of the first sealing cylinder, a first thread provided on the upper part of the inner wall of the first sleeve, a threaded head installed inside the fixed tube, and a second thread provided on the lower part of the outer surface of the threaded head, the second thread engaging with the first thread.
[0011] Furthermore, the quick-connect fitting assembly includes a second sleeve movably mounted on the outer surface of one end of the base. A third thread is provided on one side of the inner wall of the second sleeve. A second sealing cylinder is fixedly connected to the inner wall of the second sleeve. A quick-connect fitting is installed on the inner wall of the second sleeve, and a fourth thread is provided on one side of the outer surface of the quick-connect fitting. The fourth thread engages with the third thread, and one end surface of the quick-connect fitting contacts one end surface of the second sealing cylinder.
[0012] Furthermore, the connector base mounting assembly includes a connection module and a sealing module. The connection module includes a connector base component disposed on the inner wall of the other end of the base. The outer surface of the connector base component has multiple snap-fit grooves. A sealing limiting plate is fixedly connected to the inner wall of the other end of the base. The inner wall of the other end of the base is provided with multiple spring grooves corresponding to the snap-fit grooves. A socket hole is passed through one side of the inner wall of the spring groove. A connecting spring is fixedly connected to the inner wall of the spring groove. A snap-fit plate is fixedly connected to one end of the connecting spring. A pull rod passing through the socket hole is fixedly connected to one end of the snap-fit plate, and a handle is fixedly connected to one end of the pull rod.
[0013] Furthermore, the spring grooves are distributed at equal intervals on the inner wall of one end of the base, one end surface of the connector base is in contact with one end surface of the sealing limiting plate, and the snap-fit plate and the snap-fit groove are snap-fit connected.
[0014] Furthermore, the sealing module includes a sealing bolt rotatably mounted on the outer surface of the other end of the connector base component. The inner wall of the sealing bolt is provided with a No. 5 thread.

[0015] The beneficial effects of this utility model are as follows:
[0016] This invention improves the sealing effect by installing a No. 1 sealing cylinder on the upper part of the outer surface of a fixed tube and movably installing a No. 1 sleeve on the outer surface of the No. 1 sealing cylinder. When installing the threaded head, the threaded head is inserted into the fixed tube and rotated, so that the No. 2 thread and the No. 1 thread mesh and connect. The lower part of the outer surface of the threaded head contacts the No. 1 sealing cylinder to form a sealing space. When installing the connector base component by setting a connector base mounting assembly, the connector base component is inserted into the inner wall of the other end of the base. When the surface of one end of the connector base component contacts the sealing limiting plate, the snap-fit plate and the snap-fit groove are snapped together, completing the quick installation. The sealing limiting plate set on the inner wall of the other end of the base also improves the sealing effect. Installing a sealing gasket and sealing bolt on the other end of the connector base component facilitates the connection of the connector base component to the air intake pipe and improves the sealing effect of the connection with the air intake pipe.

[0027] like Figure 1-4 As shown, a novel quick-connect integrated pressure test connector includes a base 1 and a connecting hole 2. The connecting hole 2 extends through the middle of the upper part of the outer surface of the base 1, and a fixing tube 201 is fixedly connected to the inner wall of the connecting hole 2. A threaded head mounting assembly 3 is provided on the upper part of the outer surface of the fixing tube 201. A quick-connect connector integrated mounting assembly 4 is provided at one end of the base 1, and a connector base mounting assembly 5 is provided at the other end of the base 1. The threaded head mounting assembly 3 is operated to seal the threaded head to the base 1. The quick-connect connector integrated mounting assembly 4 is operated to seal the quick-connect connector 404 to the base 1. The connector base mounting assembly 5 is operated to seal the connector base 501 to the base 1.
[0028] The threaded head mounting assembly 3 includes a first sealing cylinder 301 fixedly mounted on the upper part of the outer surface of the fixed pipe 201, a first sleeve 302 movably mounted on the outer surface of the first sealing cylinder 301, a first thread 303 provided on the upper part of the inner wall of the first sleeve 302, a threaded head 304 installed inside the fixed pipe 201, a second thread 305 provided on the lower part of the outer surface of the threaded head 304, and the second thread 305 engaging with the first thread 303; after the threaded head 304 is inserted into the fixed pipe 201, the first sleeve 302 is rotated upward according to the thread engagement direction, so that the first sleeve 302 is connected to the threaded head 304 through the engagement between the first thread 303 and the second thread 305. When the connection is tight, the lower part of the outer surface of the threaded head 304 is in sealing contact with the upper surface of the first sealing cylinder 301, thereby improving the sealing effect.
[0029] The quick-connect connector assembly 4 includes a second sleeve 401 movably mounted on the outer surface of one end of the base 1. A third thread 402 is provided on one side of the inner wall of the second sleeve 401. A second sealing cylinder 403 is fixedly connected to the inner wall of the second sleeve 401. A quick-connect connector 404 is installed on the inner wall of the second sleeve 401, and a fourth thread 405 is provided on one side of the outer surface of the quick-connect connector 404. The fourth thread 405 engages with the third thread 402 for quick-connect... One end of the connector 404 contacts one end of the sealing cylinder 403; the quick-connect connector 404 is inserted into one end of the base 1, and the second sleeve 401 is rotated to one side of the quick-connect connector 404. The second sleeve 401 is connected to the quick-connect connector 404 by meshing between the third thread 402 and the fourth thread 405. At the same time, one end of the quick-connect connector 404 is sealed to the second sealing cylinder 403 to improve the sealing effect and prevent air leakage.
[0030] The connector base mounting assembly 5 includes a connection module and a sealing module. The connection module includes a connector base component 501 disposed on the inner wall of the other end of the base 1. The outer surface of the connector base component 501 has multiple snap-fit grooves 502. A sealing limiting plate 512 is fixedly connected to the inner wall of the other end of the base 1. The inner wall of the other end of the base 1 is provided with multiple spring grooves 503 corresponding to the snap-fit grooves 502. A socket 504 passes through one side of the inner wall of the spring groove 503. A connecting spring 5 is fixedly connected to the inner wall of the spring groove 503. 05. A snap-fit plate 506 is fixedly connected to one end of the connecting spring 505. A pull rod 507 passing through the insertion hole 504 is fixedly connected to one end of the snap-fit plate 506, and a handle 508 is fixedly connected to one end of the pull rod 507. When the connector base 501 is inserted into the other end of the base 1, the outer surface of the connector base 501 pushes the snap-fit plate 506 to drive the connecting spring 505 to move into the spring groove 503, so that one end of the connector base 501 contacts one end of the sealing limit plate 512.
[0031] Spring grooves 503 are evenly spaced and sequentially distributed on the inner wall of one end of the base 1. One end surface of the connector base 501 contacts one end surface of the sealing limiting plate 512, and the snap-fit plate 506 is snapped into the snap-fit groove 502. When the connector base 501 contacts one end surface of the sealing limiting plate 512, the snap-fit plate 506 and the snap-fit groove 502 are in the same position, and at this time the snap-fit plate 506 and the snap-fit groove 502 are snapped into the snap-fit.
[0032] The sealing module includes a sealing bolt 509 rotatably mounted on the outer surface of the other end of the connector base 501. The inner wall of the sealing bolt 509 is provided with a No. 5 thread 510. A sealing gasket 511 is mounted on the other end surface of the connector base 501, and the outer surface of the sealing gasket 511 contacts the inner wall of the sealing bolt 509. The sealing gasket 511 mounted on the other end surface of the connector base 501 is located inside the sealing bolt 509. When the air intake tube is connected, the sealing bolt 509 is rotatably connected to one side of the air intake tube, so that the air intake tube contacts the sealing gasket 511, thereby sealing the connection and preventing air leakage.
[0033] In summary, when installing the threaded head 304, after inserting the threaded head 304 into the fixed tube 201, rotate the first sleeve 302 upwards according to the thread engagement direction. This allows the first sleeve 302 to engage with the threaded head 304 through the engagement between the first thread 303 and the second thread 305. When the connection is tight, the lower part of the outer surface of the threaded head 304 makes sealing contact with the upper surface of the first sealing cylinder 301, improving the sealing effect. When installing the quick-connect fitting 404, insert the quick-connect fitting 404 into one end of the base 1, and rotate the second sleeve 401 to one side of the quick-connect fitting 404. The second sleeve 401 engages with the quick-connect fitting 404 through the engagement between the third thread 402 and the fourth thread 405. Simultaneously, the quick-connect fitting... One end of the connector 404 is sealed to the second sealing cylinder 403 to improve the sealing effect and prevent air leakage. When installing the connector base 501, the connector base 501 is inserted into the other end of the base 1. The outer surface of the connector base 501 pushes the snap-fit plate 506 to drive the connecting spring 505 to move into the spring groove 503. When one end of the connector base 501 contacts one end of the sealing limit plate 512, the snap-fit plate 506 and the snap-fit groove 502 are aligned. At this time, the connecting spring 505, under compression, generates a restoring force that pushes the snap-fit plate 506 into the snap-fit groove 502, realizing the snap-fit connection between the snap-fit plate 506 and the snap-fit groove 502. At the same time, the connector base 501 and the sealing limit plate 512 are sealed together.
