Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and in particular to an easy-to-install pagoda connector. Background Technology

[0002] Pagoda connectors are generally made of materials such as plastic, copper, and stainless steel. They are mostly used for quick connections in water, air, and hydraulic systems, and are suitable for applications where water, air, or oil are the medium.

[0003] Pyramid connectors consist of male and female connectors. The male and female connectors are each connected to two separate pipes, and then the male and female connectors are connected together to complete the pipe connection. When two flexible hoses need to be connected, the male and female connectors are first connected to the two hoses with cable ties, and then the male and female connectors are connected together. This connection method is cumbersome, slow, and prone to leakage. Therefore, designing an easy-to-install pyramid connector to achieve quick connection between two flexible hoses has become an urgent technical problem to be solved. Utility Model Content

[0004] In order to overcome the existing technical defects, the purpose of this utility model is to provide an easy-to-install pagoda connector to solve the above-mentioned technical problems.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0006] According to one aspect of this utility model, an easy-to-install pagoda connector is designed, comprising: a pagoda male connector, a pagoda female connector, and a connector. The pagoda male connector has a first screwing part and a first conical cavity inside its right end. The pagoda female connector consists of a second screwing part and a connecting tube that rotatably engages with the second screwing part. The connecting tube has a second conical cavity inside its left end. The pagoda female connector is detachably connected to the second screwing part. The connector has a through channel inside. The left end of the connector is inserted into the first conical cavity, and the first conical surface of the left end of the connector is parallel to the conical surface of the first conical cavity and is used to compress and fix the hose. The second conical surface of the right end of the connector is parallel to the conical surface of the second conical cavity and is used to compress and fix the hose.

[0007] Using the above technical solution, when two hoses need to be connected, the end of one hose passes through the inside of the pagoda-shaped male connector and is tightly fitted onto the first conical surface of the connector, while the end of the other hose passes through the connecting pipe and the second screw-on part and is tightly fitted onto the second conical surface of the connector. Then, the pagoda-shaped female connector is connected to the second screw-on part. During connection, the first conical surface is close to the conical surface of the first conical cavity, and the second conical surface is close to the conical surface of the second conical cavity. The connection between the two hoses is achieved by the compression of the hoses by the first conical surface and the conical surface of the first conical cavity, as well as by the compression of the hoses by the second conical surface and the conical surface of the second conical cavity. This method of connecting hoses is relatively simple and fast. The compression fit between the conical surfaces can achieve a good sealing effect, preventing leakage and resulting in good performance.

[0008] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0009] In some embodiments, the cone angle α1 of the first conical cavity is 0 < α1 ≤ 30°.

[0010] In some embodiments, the cone angle α2 of the second conical cavity is 0 < α2 ≤ 30°.

[0011] In some embodiments, the longitudinal cross-section of the first screwing part is quadrilateral, pentagonal, or hexagonal.

[0012] In some embodiments, the longitudinal cross-section of the second screwing part is quadrilateral, pentagonal, or hexagonal.

[0013] In some embodiments, the left end of the connecting pipe is provided with an annular ring, which is positioned to the left of the limiting step surface within the first screwing part.

[0014] In some embodiments, the external thread on the right end of the pagoda-shaped male connector engages with the internal thread on the second screwing part.

[0015] In some embodiments, the cone angle of the first conical cavity and the cone angle of the second conical cavity are both 18°. Attached Figure Description
