[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] Example:

[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] The utility model provides a self-locking straight-through joint, comprising a joint body 11, a through cavity 12 penetrating therethrough is provided on the joint body 11, an installation groove 14 is provided on the inner wall of the through cavity 12, a sealing rubber ring 15 is clamped in the installation groove 14, one end of a connector 13 is inserted into the through cavity 12, the sealing rubber ring 15 contacts the outer surface of the connector 13, so that the connector 13 is well sealed in the through cavity 12, and liquid or gas is effectively prevented from leaking through the gap between the joint body 11 and the connector 13; at the same time, the sealing rubber ring 15 also plays a certain degree of limiting and fixing role through close contact with the outer surface of the connector 13, thereby improving the stability of the connection; in addition, a locking component is also provided on the joint body 11, and the locking component is detachably connected to the connector 13, which is easier to install and disassemble than a traditional fixed connection, and also makes the entire joint easier to repair and replace.

[0026] Please refer to Figure 2 and Figure 3As shown, the locking assembly includes two groups of locking members 21, and two groups of mounting seats 22 are provided on the outer surface of the joint body 11. The two groups of mounting seats 22 are respectively connected to the two groups of locking members 21 through two groups of axial pins, so that the two groups of locking members 21 can rotate at a certain angle. The two groups of locking members 21 can lock the connecting head 13 through the rotation connection with the mounting seats 22, and can also be unlocked by rotation, so as to install and remove the connecting head 13. The locking member 21 is installed on the mounting seat 22 through two groups of axial pins, so that the locking member 21 can remain stable and not easy to fall off, and can be flexibly rotated to switch between the locked and unlocked states, which well realizes the combination of the detachable structure of the connecting head 13 and the reliable locking of the connection. Compared with the use of a single locking component, the use of two groups of symmetrically arranged locking members 21 can ensure the locking strength while also making it easier to operate locking and unlocking.

[0027] Please refer to Figure 3 and Figure 4 As shown, the straight-through connector realizes a reliable connection between the connector head 13 and the connector body 11 through a locking assembly. Specifically, two groups of through grooves are provided on the inner side of the through cavity 12 corresponding to the two groups of mounting seats 22. Correspondingly, one side of the two groups of locking members 21 is provided with a locking head 23, and at the same time, a matching locking groove 24 is also provided on the peripheral side of the connector head 13; when making a connection, the connector head 13 is first aligned with the through cavity 12 at one end of the connector body 11 and inserted. Since the through cavity 12 is provided with two groups of through grooves, the two groups of locking heads 23 can be moved inward through the through grooves and detachably clamped in the corresponding locking grooves 24 on the connector head 13. When the two groups of locking heads 23 are both clamped in the locking grooves 24, the connection between the connector body 11 and the connector head 13 through the locking assembly is realized; this design using the cooperation of the through grooves and the locking grooves not only ensures the reliability of the connection, but also realizes the detachability of the connector head 13, and at the same time, the operation is simple and convenient, so that the straight-through connector meets the basic connection function.

[0028] Please refer to Figure 3 As shown, the straight-through connector not only realizes the reliable connection between the connector 13 and the connector body 11, but also takes into account the convenience of disassembly; specifically, the two groups of locking members 21 are each provided with a through hole at one end away from the locking head 23, and two groups of pull rings 25 are respectively provided in the two through holes; when the connector 13 needs to be disassembled, it is only necessary to pull the two groups of pull rings 25 at the same time, and pulling the pull rings 25 will cause the two groups of locking members 21 to rotate through the rotational connection with the mounting seat 22, and the rotation of the locking member 21 will directly drive the locking head 23 to move out of the locking groove 24 on the connector 13, thereby achieving unlocking, and the connector body 11 and the connector 13 can be easily disassembled without using any other tools; this unlocking by using the pull ring to drive the locking member to rotate not only ensures the reliability of unlocking, but also greatly improves the convenience of operation during on-site maintenance.

[0029] Please refer to Figure 2 and Figure 3 As shown, the straight-through connector not only realizes reliable connection and convenient disassembly through the locking component, but also has a shock-absorbing and rebound component arranged in the through cavity 12, so that the connector 13 has a shock-absorbing and protective effect during operation, and is convenient for quick disassembly; specifically, the shock-absorbing and rebound component includes a spring 31 and a limit ring 32, wherein the bottom of the spring 31 contacts the inner wall of the through cavity 12, and the limit ring 32 is arranged on the top, and the top surface of the limit ring 32 contacts the connector 13, so that when the connector 13 is impacted or vibrated during operation, The elasticity of the spring 31 can achieve a shock-absorbing effect. At the same time, when disassembling the connector 13, the user only needs to pull the two sets of pull rings 25 to release the lock of the locking assembly on the connector 13. Due to the limiting effect of the limit ring 32, the connector 13 will automatically detach from the through cavity 12 under the action of the rebound force of the spring 31 without manual pulling, and the connection with the connector body 13 will be automatically released, which greatly improves the convenience of disassembly. The setting of the shock-absorbing rebound assembly not only protects the connector 13, but also enhances the convenience of the product.

[0030] Please refer to Figure 4 As shown, a hexagonal joint 16 is provided at one end of the connector 13 away from the connector body 11, and an internal thread 17 is provided on the top of the hexagonal joint 16. The setting of the internal thread 17 enables the connector 13 to be directly connected to various external pipelines for use. As long as the threaded portion at one end of the external pipeline is screwed into the internal thread 17, a quick connection can be achieved, thereby improving the practicality of the connector 13; both ends of the connector 13 can be efficiently connected and used, one end is protected from impact by a shock-absorbing rebound component, and the other end is installed by the internal thread 17, thereby giving full play to the role of the connector 13, which not only ensures the reliability of the product itself, but also provides convenience for users in operation.

[0031] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
