The heads of the left, right, and front docking blocks are all equipped with sealing plates. The top, left, and right circular tube interfaces are all provided with first through holes in the middle. By setting the top, left, and right circular tube interfaces above and below the central body and cooperating with the circular sealing block to achieve opening and closing, and by setting the left, right, and front docking blocks on the outer ring of the central body and cooperating with the splicing square tube and sealing plates to achieve opening and closing, multiple interface combinations can be switched, thus enabling the use of various tee connectors of different specifications and improving applicability. However, this patent still has the following problems.

[0004] In the aforementioned patent, although the circular sealing block is used to seal the top, left, and right circular pipe interfaces when the connection method of the tee connector needs to be changed, the use of a threaded connection means that the threaded surface may experience wear, deformation, and corrosion after prolonged use. Once the thread is damaged, it will affect the tightness and sealing of the connection. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art that the threaded connection between the circular sealing block and the circular pipe interface may cause wear, deformation, and corrosion on the threaded surface after long-term use, and to propose a three-way connector assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a three-way connector assembly, comprising a central body, wherein the outer wall of the central body is provided with three connector structures;

[0007] The joint structure includes a circular tube that passes through and is fixedly connected to the central body. The inner wall of the circular tube is provided with an internal thread, and the outer wall of the circular tube is provided with a groove. Each of the three joint structures is provided with a sealing structure at one end.

[0008] The sealing structure includes a threaded rod that is threadedly connected to an internal thread. A sealing plate is fixedly installed on the top of the threaded rod, and a connecting block is fixedly installed on the bottom of the sealing plate. A limit groove is formed at one end of the connecting block, and a first spring is fixedly installed on the inner wall of the limit groove. A locking block is fixedly installed at one end of the first spring, and a connecting rod is fixedly installed at one end of the locking block. One end of the connecting rod passes through the connecting block and is fixedly installed with a pull plate.

[0009] Preferably, the outer wall of the center body is provided with three connecting structures, each connecting structure including a docking block. The outer wall of the docking block is fixedly connected to the center body. A T-shaped groove is provided on the top of the docking block, and a first through hole is provided through the inner wall of the T-shaped groove.

[0010] Preferably, a fixing plate is fixedly installed on the top of the docking block, two second springs are fixedly installed on the outer wall of the fixing plate, a baffle is fixedly installed on one end of each of the two second springs, and a movable plate is fixedly installed on the top of the baffle.

[0011] Preferably, a limit rod is fixedly installed at one end of the baffle near the second spring, and one end of the limit rod is slidably inserted into the fixed plate.

[0012] Preferably, each of the three connecting structures has a splicing structure at the end furthest from the central body. The splicing structure includes a square tube, and a T-shaped plate is fixedly installed on the outer wall of the square tube. The T-shaped plate and the outer wall of the square tube are both provided with a second through hole, and the T-shaped plate is slidably connected to the T-shaped groove.

[0013] Preferably, a sealing ring is fixedly installed at the bottom of the sealing plate, and a sealing groove is provided at the top of the round tube.

[0014] Preferably, the outer wall of the card block is in contact with the inner wall of the card slot.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, when in use, the worker pulls the pull plate, which drives the locking block to move through the connecting rod. Then, the worker inserts the threaded rod into the round tube, so that the threaded rod is threadedly connected with the internal thread. When the threaded rod is fully inserted into the round tube, the locking block moves to the side of the locking groove. The worker releases the pull plate, and the elastic force of the first spring pushes the locking block into the locking groove. This further improves the stability of the connection. Even when the thread is worn, the tightness of the connection can still be guaranteed.

[0017] 2. In this utility model, when replacing the square tube, the worker inserts the T-shaped plate into the T-groove. When the T-shaped plate contacts the inclined surface of the baffle, the T-shaped plate pushes the baffle to move, and the second spring is compressed. When the T-shaped plate is fully inserted into the T-groove, the baffle returns to its original position under the elastic force of the second spring. At this time, the bottom of the baffle is in contact with the top of the T-shaped plate, thus preventing the T-shaped plate from falling out of the T-groove when the square tube is in use.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figures 1-5 As shown, this utility model provides a three-way connector assembly, including a central body 1, and three connector structures 2 are provided on the outer wall of the central body 1;

[0027] The connector structure 2 includes a round tube 201, which passes through and is fixedly connected to the central body 1. The inner wall of the round tube 201 is provided with an internal thread 202, and the outer wall of the round tube 201 is provided with a groove 203. Each of the three connector structures 2 is provided with a sealing structure 3 at one end.

[0028] The sealing structure 3 includes a threaded rod 301, which is threadedly connected to an internal thread 202. A sealing plate 302 is fixedly installed on the top of the threaded rod 301, and a connecting block 303 is fixedly installed on the bottom of the sealing plate 302. A limiting groove 304 is opened at one end of the connecting block 303, and a first spring 305 is fixedly installed on the inner wall of the limiting groove 304. A locking block 306 is fixedly installed at one end of the first spring 305, and a connecting rod 307 is fixedly installed at one end of the locking block 306. One end of the connecting rod 307 passes through the connecting block 303 and is fixedly installed with a pull plate 308.

[0029] The effect achieved by the entire embodiment 1 is as follows: When in use, the operator pulls the pull plate 308, and the pull plate 308 drives the locking block 306 to move through the connecting rod 307. Then, the operator inserts the threaded rod 301 into the round tube 201, so that the threaded rod 301 is threadedly connected with the internal thread 202. When the threaded rod 301 is fully inserted into the round tube 201, the locking block 306 moves to the side of the locking groove 203. The operator releases the pull plate 308, and the elastic force of the first spring 305 pushes the locking block 306 into the locking groove 203. In this way, the stability of the connection can be further improved, and the tightness of the connection can still be guaranteed when the thread is worn.

[0030] Example 2, as Figures 1-5 As shown, the outer wall of the central body 1 is further provided with three connecting structures 4. The connecting structure 4 includes a docking block 401. The outer wall of the docking block 401 is fixedly connected to the central body 1. A T-shaped groove 402 is opened on the top of the docking block 401. A first through hole 403 is opened through the inner wall of the T-shaped groove 402.

[0031] Furthermore, a fixing plate 404 is fixedly installed on the top of the docking block 401, and two second springs 405 are fixedly installed on the outer wall of the fixing plate 404. A baffle 406 is fixedly installed on one end of the two second springs 405, and a movable plate 407 is fixedly installed on the top of the baffle 406.

[0032] Furthermore, a limiting rod 408 is fixedly installed on one end of the baffle 406 near the second spring 405, and one end of the limiting rod 408 is slidably inserted into the fixing plate 404.

[0033] Furthermore, each of the three connecting structures 4 has a splicing structure 5 at the end furthest from the central body 1. The splicing structure 5 includes a square tube 501, and a T-shaped plate 502 is fixedly installed on the outer wall of the square tube 501. The T-shaped plate 502 and the outer wall of the square tube 501 are both provided with a second through hole 503. The T-shaped plate 502 is slidably connected to the T-shaped groove 402.

[0034] Furthermore, a sealing ring 309 is fixedly installed at the bottom of the sealing plate 302, and a sealing groove 204 is opened at the top of the round tube 201.

[0035] Furthermore, the outer wall of the card block 306 fits against the inner wall of the card slot 203, and when the card block 306 enters the card slot 203, the sealing plate 302 is fixed.

[0036] The effect achieved by the entire embodiment 2 is that when replacing the square tube 501, the worker inserts the T-shaped plate 502 into the T-shaped groove 402. When the T-shaped plate 502 contacts the inclined surface of the baffle 406, the T-shaped plate 502 pushes the baffle 406 to move, and the second spring 405 is compressed. When the T-shaped plate 502 is fully inserted into the T-shaped groove 402, the baffle 406 is reset under the elastic force of the second spring 405. At this time, the bottom of the baffle 406 is in contact with the top of the T-shaped plate 502, thus preventing the T-shaped plate 502 from falling out of the T-shaped groove 402 when the square tube 501 is in use.

[0037] Working principle: In use, the operator pulls the pull plate 308, which moves the locking block 306 via the connecting rod 307. Then, the operator inserts the threaded rod 301 into the round tube 201, making the threaded rod 301 threadedly connected to the internal thread 202. When the threaded rod 301 is fully inserted into the round tube 201, the locking block 306 moves to the side of the locking groove 203. The operator releases the pull plate 308, and the elastic force of the first spring 305 pushes the locking block 306 into the locking groove 203. This further improves the stability of the connection, ensuring a tight connection even when the threads wear. At the same time, the sealing ring 309 enters the sealing groove 204, further improving the sealing performance. When replacing the square tube 501, the worker inserts the T-shaped plate 502 into the T-slot 402. When the T-shaped plate 502 contacts the inclined surface of the baffle 406, the T-shaped plate 502 pushes the baffle 406 to move, compressing the second spring 405. When the T-shaped plate 502 is fully inside the T-slot 402, the baffle 406 returns to its original position under the elastic force of the second spring 405. At this time, the bottom of the baffle 406 is in contact with the top of the T-shaped plate 502, thus preventing the T-shaped plate 502 from falling out of the T-slot 402 during use of the square tube 501. For disassembly, the worker pulls the moving plate 407, which moves the baffle 406, allowing the worker to remove the T-shaped plate 502.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
