Description

Technical Field

[0001] This utility model relates to a push-up assembly and a quick-connector for coating, filling, leak detection, and insulation. Background Technology

[0002] In actual production, for products requiring airtight leak testing, a leak detection connector is typically connected to the pipe fittings on the product under test. Then, an air source is connected to the leak detection connector, and gas is introduced into the product under test. The product is then placed in water to observe for bubbles, thus determining if there is a leak. After leak testing, the product under test is placed in a coating solution and coated using an electrolytic cell. Due to customer requirements, some pipe fittings may not be coated. In this case, the product under test and the leak detection connector are typically placed together in the coating solution for coating. The leak detection connector must have a certain degree of insulation to ensure that the connector and the pipe fitting portion extending into it are not coated.

[0003] Chinese utility model patent 201921262389.1 discloses an insulating leak detection connector, including a connector body, an insulating seat slidably sleeved on the tail of the connector body, and a driving mechanism on the connector body; the insulating seat is connected to the head of an insulating shell, and the tail of the insulating shell is provided with a stop ring and an insertion port; the insulating shell is provided with a first insulating sleeve, a second insulating sleeve, a clamp, a first compression sleeve, and a second compression sleeve, and the second insulating sleeve is elastic; the inner wall of the clamp is provided with an elastic element, and the two ends of the outer wall of the clamp are respectively provided with a first conical surface and a second conical surface. The driving mechanism includes a fixed seat fixed to the head of the connector body, a movable seat fixed to the insulating seat, two connecting rods symmetrically arranged on both sides between the fixed seat and the movable seat, and a wrench, with wrench arms symmetrically extending on both sides, and an eccentric wheel provided on the inner side of the wrench arms; one of the fixed seat and the movable seat is rotatably connected to the eccentric wheel through a fixing element, and the other is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is mounted on the eccentric wheel. With the arrangement of the insulating base, insulating shell, first insulating sleeve, and second insulating sleeve, it has excellent insulation and sealing properties, which can effectively prevent other metal parts of this utility model and some pipe parts located within this utility model from being coated during the coating process, thus meeting customer usage needs.

[0004] However, this type of insulated leak detection connector also has drawbacks: it requires reciprocating wrench operation, which is quite strenuous. Furthermore, the internal parts are prone to wear due to movement, often necessitating adjustment of the connector's position; otherwise, the pipe clamping may not be secure. Additionally, when inserting the pipe, the pipe directly impacts the internal parts, making operation somewhat uncomfortable. Summary of the Invention

[0005] The purpose of this utility model is to provide a push-up assembly and a quick-connect coupling for coating, filling, leak detection, and insulation, which can solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: This utility model provides a pushing assembly, including an insulating top block. The head of the insulating top block is provided with a first movable cavity with an opening on one side. The first movable cavity is provided with an elastic support member that allows fluid to pass through. The tail of the insulating top block has a first channel that communicates with the first movable cavity.

[0007] Preferably, the elastic support includes a spring support body and a support rod that lies across the head of the spring support body, the support rod being integrally formed with the spring support body.

[0008] This utility model also provides a quick-connect insulating connector for coating, filling, and leak detection, comprising a connector body and a hollow insulating shell. The head of the insulating shell has an inwardly tapering blocking portion, in which an insertion port for inserting a pipe fitting is formed. An insulating clamping assembly for insulating and sealing the pipe fitting is provided on the inner side of the blocking portion. The insulating clamping assembly has a clamping channel opposite to the insertion port. The head of the connector body is provided with a pull rod, through which a second channel passes. A sliding seat is slidably provided on the outside of the pull rod, and the inner wall of the sliding seat is slidably sealed with the outer wall of the pull rod. The sliding seat is connected to the head of the insulating shell. The head of the pull rod extends into the insulating shell and is provided with a pushing assembly, which is the aforementioned pushing assembly. The outer wall of the insulating top block of the pushing assembly is slidably sealed with the inner wall of the insulating shell. The first channel of the pushing assembly is connected to the second channel. The first movable cavity of the push assembly is connected to the clamping channel. A second movable cavity is formed between the insulating top block, pull rod, sliding seat, and insulating shell of the push assembly. A first elastic element is provided in the second movable cavity. The first elastic element is supported between the insulating top block and the sliding seat of the push assembly, so that the head of the insulating top block of the push assembly pushes against the insulating clamping assembly, thereby clamping the pipe fitting by the insulating clamping assembly. A wrench is provided outside the connector body. The two sides of the wrench are rotatably connected to the two sides of the connector body. Support parts are provided on the two sides of the wrench. The support parts can push against the sliding seat. When the wrench is pressed, the wrench rotates relative to the connector body. The support parts rotate accordingly and push against the sliding seat. The sliding seat moves away from the connector body and drives the insulating shell and the insulating clamping assembly away from the insulating top block of the push assembly, thereby releasing the pipe fitting by the insulating clamping assembly.

[0009] Preferably, the second channel and the second movable cavity are connected by a connecting hole.

[0010] Preferably, the connecting hole is provided on the pull rod located at the second movable cavity; or, the connecting hole is provided on the pull rod located in the insulating top block of the pushing assembly and passes through the insulating top block and the pull rod of the pushing assembly.

[0011] Preferably, a sealing ring is provided between the insulating outer shell and the sliding seat.

[0012] Preferably, the insulating clamping assembly includes, from the outside to the inside, a first insulating sealing washer, a first compression sleeve, a clamping jaw, a second compression sleeve, and a second insulating sealing washer, which are sequentially disposed in the insulating outer shell. The first insulating sealing washer seals between the blocking part and the first compression sleeve. The second insulating sealing washer seals between the insulating top block of the pushing assembly and the second compression sleeve and partially extends into the head of the insulating top block of the pushing assembly. The clamping jaw is composed of at least two arc-shaped clamping jaw pieces, which form a ring. A second elastic element is provided between adjacent clamping jaws to allow the clamping jaw pieces to open up to each other. One end of the outer wall of the clamping jaw has a first conical surface opposite to the first compression sleeve, and the other end of the outer wall of the clamping jaw has a second conical surface opposite to the second compression sleeve.

[0013] Preferably, the two end faces of the gripper pieces are provided with support holes, and the second elastic element is a spring, with the two ends of the spring respectively located in the support holes of two adjacent gripper pieces.

[0014] Preferably, the first extrusion sleeve has a third conical surface opposite to the first conical surface, and the second extrusion sleeve has a fourth conical surface opposite to the second conical surface.

[0015] Preferably, the head of the pull rod is inserted into the tail of the insulating top block of the push assembly and fixed to the insulating top block of the push assembly by a fixing pin.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the setting of an insulating shell, an insulating top block, and an insulating clamping assembly, has excellent insulation and sealing performance. It can not only be used for leak detection and filling of pipe fittings, but also effectively prevent other metal parts of this utility model and some pipe fittings located within this utility model from being coated during the coating process, meeting customer needs. 2. This utility model, through the cooperation of a wrench and a first elastic element, is very quick and labor-saving to operate. If parts are worn, the presence of the first elastic element allows for real-time adjustment of the position of the pull rod and the insulating top block, resulting in a more secure clamping of the pipe fittings. 3. The insulating top block of this utility model is equipped with an elastic support element. When inserting a pipe fitting, the elastic support element acts as a buffer, preventing the pipe fitting from directly impacting the insulating top block, thus ensuring comfortable operation.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] As shown in Figure 3, this utility model provides a pushing assembly, including an insulating top block 1. The head of the insulating top block 1 has a first movable cavity 2 with an opening on one side. The first movable cavity 2 has an elastic support member 3 that allows fluid to pass through. The tail of the insulating top block 1 has a first channel 4 that communicates with the first movable cavity 2. This utility model can be installed in a quick connector and has an insulating pushing function. When a pipe is inserted, the pipe contacts the elastic support member 3, which has a buffering effect, making operation more comfortable.

[0022] Preferably, the elastic support 3 includes a spring support body and a support rod that lies horizontally on the head of the spring support body. The support rod is integrally formed with the spring support body. In use, the support rod can lie horizontally in the middle of the pipe without blocking it, and the spring support body is elastic, which can play a good buffering role.

[0023] As shown in Figures 1 and 2, this utility model also provides a quick-connect insulating connector for coating, filling, and leak detection, including a connector body 5 and a hollow insulating shell 6. The head of the insulating shell 6 has an inwardly contracting blocking portion 7, in which an insertion port 8 for inserting a pipe is formed. The inner side of the blocking portion 7 is provided with an insulating clamping assembly for insulating and sealing the pipe. The insulating clamping assembly has a clamping channel 9 opposite to the insertion port 8. The head of the connector body 5 is provided with a pull rod 10, through which a second channel 11 passes. A sliding seat 12 is slidably provided on the outside of the pull rod 10, and the inner wall of the sliding seat 12 is slidably sealed with the outer wall of the pull rod 10. The sliding seat 12 is connected to the head of the insulating shell 6. The head of the pull rod 10 extends into the insulating shell 6 and is provided with a pushing assembly, which is the pushing assembly described above. The outer wall of the insulating top block 1 of the pushing assembly is flush with the insulating shell 6. The inner walls of the push assembly slide and seal. The first channel 4 of the push assembly is connected to the second channel 11. The first movable cavity 2 of the push assembly is connected to the clamping channel 9. The insulating top block 1, pull rod 10, sliding seat 12 and insulating shell 6 of the push assembly form a second movable cavity 13. The second movable cavity 13 is provided with a first elastic element 14, preferably a spring. The first elastic element 14 is supported between the insulating top block 1 and the sliding seat 12 of the push assembly, so that the head of the insulating top block 1 of the push assembly pushes against the insulating clamping assembly, thereby making the insulating clamping assembly clamp the pipe. The connector body 5 is provided with a wrench 15. The two sides of the wrench 15 are rotatably connected to the two sides of the connector body 5 by screws 16. The two sides of the wrench 15 are provided with support parts 17, which can push against the sliding seat 12. Pressing the wrench 15, the wrench 15 is relative to the connector body 5. When rotated, the support part 17 rotates accordingly and pushes against the sliding seat 12. The sliding seat 12 moves away from the joint body 5 and drives the insulating shell 6 and the insulating clamping assembly away from the pushing assembly insulating top block 1, thereby causing the insulating clamping assembly to release the pipe fitting.

[0024] In use, pressing the wrench 15 brings it closer to the insulating shell 6, causing the wrench 15 to rotate relative to the connector body 5. The support part 17 also rotates and presses against the sliding seat 12, thus moving the sliding seat 12 away from the connector body 5 and causing the insulating shell 2 and insulating clamping assembly to move away from the insulating top block 1. The insulating clamping assembly is in a non-clamping state, and the first elastic element 14 is compressed. Then, the pipe is inserted from the insertion port 8 of the insulating shell 6 into the clamping channel 9 of the insulating clamping assembly and presses against the elastic support 17. The elastic support 3 acts as a buffer, preventing the pipe from directly impacting the insulating top block 1. Then, releasing the wrench 15 causes the first elastic element 14 to bring the sliding seat 12 closer to the connector body 5, causing the insulating shell 6 and insulating clamping assembly to reset. The insulating top block 1 then pushes against the insulating clamping assembly again, clamping the pipe and sealing the portion of the pipe extending into the insulating shell 6. The operation is very convenient, quick, and labor-saving. The tail of the connector body 5 is connected to a gas source, allowing gas to be injected into the pipe. After gas injection, it can be placed in water to observe for air bubbles, thus determining whether the product under inspection has any leaks, completing the leak detection. If there are no leaks, the pipe and this utility model are placed together in the coating solution and coated using the principle of an electrolytic cell. Due to the certain sealing and insulation properties of this utility model, it can effectively prevent other metal parts of this utility model (such as wrenches, pull rods, connector bodies, sliding seats, etc.) and some pipe parts located within this utility model from being coated during the coating process. After coating is completed, pressing the wrench 15 again moves the sliding seat 12 away from the connector body 5, thereby moving the insulating shell 6 and the insulating clamping assembly away from the insulating top block 1. The insulating clamping assembly is in a non-clamping state, thus releasing the pipe, which can then be pulled out of the insulating clamping assembly. After long-term use, if the parts wear out, the presence of the first elastic element 14 can adjust the position of the insulating top block 1 in the insulating shell 6 in real time, making the pipe clamping more secure.

[0025] Preferably, the second channel 11 and the second movable cavity 13 are connected by a connecting hole 18, which is located on the pull rod 10 in the second movable cavity 13; alternatively, the connecting hole is located on the pull rod in the insulating top block of the pushing assembly and passes through the insulating top block and the pull rod of the pushing assembly. The position of the connecting hole 18 only needs to connect the second channel 11 and the second movable cavity 13. When the insulating clamping assembly clamps the pipe, air is injected into the pipe. The gas can enter the second movable cavity 13 through the connecting hole 18. The air pressure in the second movable cavity 13 will push the sliding seat 12 closer to the joint body 5, thereby causing the insulating top block 1 to move closer to the insulating clamping assembly, thus helping the insulating clamping assembly to firmly clamp the pipe, making the clamping more reliable. When releasing the pipe, the inflation stops, the air pressure in the second movable cavity 13 is lost, and the wrench 15 can be operated normally to release the pipe using the insulating clamping assembly.

[0026] Preferably, a sealing ring 19 is provided between the insulating shell 6 and the sliding seat 12, which provides a good sealing effect.

[0027] Preferably, the insulating clamping assembly includes, from the outside to the inside, a first insulating sealing gasket 20, a first compression sleeve 21, a clamping jaw 22, a second compression sleeve 23, and a second insulating sealing gasket 24, which are sequentially disposed in the insulating outer shell 6. The first insulating sealing gasket 20 seals between the blocking part 7 and the first compression sleeve 21. The second insulating sealing gasket 24 seals between the insulating top block 1 of the pushing assembly and the second compression sleeve 23 and partially extends into the head of the insulating top block 1 of the pushing assembly. The clamping jaw 22 is composed of at least two arc-shaped clamping jaw pieces, which form a ring. A second elastic element is provided between adjacent clamping jaws to allow the clamping jaw pieces to open up to each other. One end of the outer wall of the clamping jaw 22 has a first conical surface opposite to the first compression sleeve 21, and the other end of the outer wall of the clamping jaw 22 has a second conical surface opposite to the second compression sleeve 23. Under the pushing force of the insulating top block 1 and the limiting force of the blocking part 7 of the insulating outer shell 6, the first compression sleeve 21 and the second compression sleeve 23 are brought closer together. The gripper 22 contracts inward under the interaction of the first compression sleeve 21 and the second compression sleeve 23, thus clamping the pipe fitting. At the same time, the second elastic element is compressed, and the first insulating sealing gasket 20 and the second insulating sealing gasket 24 are also compressed and deformed, sealing between the pipe fitting and the insulating outer shell 6 and the insulating top block 1, resulting in a good sealing effect. When the insulating top block 1 no longer pushes against the insulating clamping assembly, the gripper 22 opens outward under the action of the second elastic element, thus releasing the pipe fitting.

[0028] Preferably, the two end faces of the gripper are provided with support holes 25, and the second elastic element is a spring, with the two ends of the spring respectively located in the support holes 25 of the two adjacent gripper pieces, which has a simple structure.

[0029] Preferably, the first extrusion sleeve 21 is provided with a third conical surface opposite to the first conical surface, and the second extrusion sleeve 23 is provided with a fourth conical surface opposite to the second conical surface, which has a guiding function and ensures smooth operation.

[0030] Preferably, the head of the pull rod 10 is inserted into the tail of the insulating top block 1 of the push assembly and fixed to the insulating top block 1 of the push assembly by the fixing pin 26, which is convenient for installation.

[0031] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
