First of all, in the face of pipes with different materials and specifications, the versatility and compatibility of traditional joints are limited, and different models need to be customized, increasing costs. Secondly, due to the possible tiny gaps between pipes, traditional joints are difficult to ensure long-term stable sealing effects and there is a risk of leakage. Content of the Utility Model

[0003] The purpose of the utility model is to provide a connecting pipe joint to solve the problems raised in the above background art. To achieve the above purpose, the utility model provides the following technical solution: A connecting pipe joint includes a first housing and a second housing. The first housing and the second housing are symmetrically arranged. A sealing component is provided between the first housing and the second housing for sealing the connection of connecting pipes with different sizes. The first housing and the second housing are detachably connected.

[0004] Preferably, the sealing component includes sealing elements. There are two sealing elements, and the two sealing elements are respectively arranged corresponding to the first housing and the second housing. A number of first connecting parts are installed along the circumferential direction on the inner walls of the first housing and the second housing. The other end of each first connecting part is connected to a spring, and the other end of each spring is connected to a second connecting part.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to make the implementation means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings. In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection or a mechanical connection, and it can also be an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and the interiors of two components can be communicated.

[0016] Embodiment 1

[0017] As Figure 1-2A shown connecting pipe joint includes a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are symmetrically arranged. When the first housing 1 and the second housing 2 are combined together, a cylindrical inner cavity can be formed. By inserting two connecting pipes from both ends of the inner cavity respectively, the two connecting pipes can be connected. Different from the traditional connector, the first housing 1 and the second housing 2 directly seal the connection part of the two connecting pipes, which can avoid the problem of easy leakage at the connection part between the traditional connector and the connecting pipe, and has a better leak-proof effect. Installation holes 7 are correspondingly arranged on both the first housing 1 and the second housing 2. Bolts 3 are arranged in one-to-one correspondence with the installation holes 7. A nut 11 is sleeved on the outer wall of each bolt 3. By screwing the bolts 3 into the two installation holes 7, then sleeving the nuts 11 on the outer walls of the bolts 3 and tightening the nuts 11, the first housing 1 and the second housing 2 can be detachably connected, with simple installation and convenient operation.

[0018] Embodiment 2

[0019] On the basis of Embodiment 1, a further improvement lies in that, as Figure 2-3 shown, a sealing assembly for sealing the connection part of connecting pipes with different sizes is provided between the first housing 1 and the second housing 2. The sealing assembly includes sealing members 5. There are two sealing members 5, and the two sealing members 5 are respectively arranged corresponding to the first housing 1 and the second housing 2. The two sealing members 5 are both arc-shaped and are made of elastic materials. The two sealing members 5 can form a circular inner cavity when combined together, which is convenient for the connecting pipe to be inserted. A number of first connecting members 9 are installed along the circumferential direction on the inner walls of the first housing 1 and the second housing 2. The other end of each first connecting member 9 is connected to a spring 10. The other end of each spring 10 is connected to a second connecting member 12. The other ends of a number of second connecting members 12 are respectively connected to one side of the two sealing members 5. Place the two connecting pipes on one of the sealing members 5, then buckle the other sealing member 5 on the other side of the connecting pipe, and lock the first housing 1 and the second housing 2. Since the sealing member 5 is made of elastic material, it will contract outward under the extrusion of the outer wall of the connecting pipe, compress the spring 10, and thus the connecting pipe can be clamped in the sealing member 5, making the inner wall of the sealing member 5 closely adhere to the outer wall of the connecting pipe, making the two connecting pipes not easy to shake, improving the connection stability, sealing the connection part, and the sealing member 5 can seal and fix the connection parts of connecting pipes with various sizes. When connecting connecting pipes with different sizes, within a certain size range, there is no need to replace the first housing 1 and the second housing 2, which is very convenient, can improve the versatility and compatibility of the connector, and reduce the customization cost of the connector.

[0020] Furthermore, protective plates 6 are connected to the front, back, left, and right sides of one side of the two seals 5. The other ends of the protective plates 6 are respectively connected to the outer walls of the first housing 1 and the second housing 2. The protective plates 6 are made of elastic materials and can expand and contract. They can expand and contract along with the spring 10. The springs 10 are arranged in the inner cavities formed by the protective plates 6, which can prevent the liquid from damaging the springs 10 when the connecting pipe leaks, improve the service life of the springs 10, and improve the sealing effect of the connector.

[0021] Furthermore, a sealing ring 4 is also included. Sealing grooves 8 are symmetrically formed on the inner walls of the first housing 1 and the second housing 2. The outer wall of the sealing ring 4 is closely attached to the inner walls of the two sealing grooves 8. The sealing ring 4 is made of elastic materials. The outer wall of the sealing ring 4 and the inner walls of the sealing grooves 8 are both arc-shaped. The sealing ring 4 is annular. The outer wall of the sealing ring 4 is closely attached to the inner walls of the sealing grooves 8. The sealing ring 4 is sleeved on the outer wall of the connecting pipe, which can block the leaked liquid at the connection and further improve the sealing performance of the connector.

[0022] It should be noted that the above-mentioned elastic materials can all be made of rubber materials. Rubber materials have good sealing performance and elasticity, which can improve the sealing effect.

[0023] The technological process and working principle of the present utility model are as follows: When connecting two connecting pipes, the two connecting pipes are respectively placed on both sides of the inner cavity of one of the seals 5. Then, another seal 5 is closed. The bolts 3 are inserted into the two mounting holes 7, and the nuts 11 are screwed onto the outer walls of the bolts 3. The nuts 11 are tightened, and the first housing 1 and the second housing 2 can be connected. At this time, the connecting pipe squeezes the inner wall of the seal 5, causing the spring 10 to contract, so that the outer wall of the connecting pipe closely adheres to the inner wall of the seal 5, sealing the connection. Since the seal 5 has good elasticity, when connecting different-sized connecting pipes, it can still seal and fix the connection. Within a certain range of connecting pipe sizes, there is no need to replace the seal 5, achieving the effect of improving the versatility and compatibility of the connector. Additionally, by setting the replaceable sealing ring 4 to cooperate with the sealing groove 8, the leakage of liquid is blocked, further improving the sealing performance of the connector and preventing liquid leakage.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
