[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] A connecting base for a linear actuator housing, such as Figures 1 to 3 As shown, it includes a connecting seat body 1, on which a connecting ring 2 is integrally formed. The connecting seat body 1 is used to install a linear actuator, and the connecting ring 2 is used to connect an external valve body.

[0025] It should be noted that in the prior art, the connecting seat body 1 and the connecting ring 2 are usually connected by snap-fit ​​or riveting. As the service time increases and due to the influence of load and the reaction force of the linear actuator, the connection between the two may fail. In view of the above, this embodiment integrates the connecting seat body 1 and the connecting ring 2 into one piece, thereby effectively ensuring the strength, stability and reliability of the structure and avoiding connection failure. More importantly, since the connecting seat body 1 and the connecting ring 2 are integrally formed, the manufacturing process is more convenient, eliminating the operation process required to connect and assemble the connecting seat body 1 and the connecting ring 2, and thus improving production efficiency.

[0026] Furthermore, to improve the overall structural strength, both the main body 1 of the connecting seat and the connecting ring 2 integrally formed therewith are made of metal.

[0027] The main body 1 of the connecting seat is provided with a clearance hole 3 that is coaxial with the connecting ring 2, so as to avoid interference with the linkage between the linear actuator and the external valve body.

[0028] A connecting cap 4 is rotatably mounted on the connecting ring 2. The connecting cap 4 is threadedly connected to the external valve body. That is, the connecting ring 2 is connected to the external valve body through the connecting cap 4. Since the external valve body and the connecting cap 4 are connected by a threaded connection, the connecting cap 4 can rotate relative to the connecting ring 2, which makes the operation of the threaded connection simpler and more convenient, and can effectively improve the assembly efficiency.

[0029] A limiting element is provided on the connecting ring 2 to prevent the connecting cap 4 from detaching from the connecting ring 2. In this embodiment, the limiting element includes a retaining spring 5. An annular groove 6 is provided on the outer side wall of the connecting ring 2, and the retaining spring 5 is disposed in the annular groove 6. An annular flange 7 is provided on the inner side wall of the connecting cap 4. The retaining spring 5 abuts against the annular flange 7. Specifically, an inclined surface 8 is provided on the annular flange 7, and the retaining spring 5 abuts against the inclined surface 8. That is, the connecting cap 4 is limited along the axial direction of the connecting ring 2 by the abutting action of the two, which not only allows the connecting cap 4 to rotate relative to the connecting ring 2, but also prevents the connecting cap 4 from detaching from the connecting ring 2.

[0030] As an alternative, the limiting component includes a limiting ring, which is threadedly connected to the connecting ring 2. The limiting ring abuts against the inclined surface 8 on the annular flange 7, thereby preventing the connecting cap 4 from disengaging from the connecting ring 2. The outer diameter of the limiting ring is smaller than the inner diameter of the connecting cap 4, so only the limiting ring needs to be rotated during disassembly and assembly.

[0031] The inclined surface 8 can guide the snap ring 5. It should be noted that in this embodiment, the inclined surface 8 points to the annular groove 6. When installing the snap ring 5, first put the snap ring 5 into the connecting cap 4 and continue to apply pressure until the snap ring 5 abuts against the inclined surface 8 and enters the annular groove along the inclined surface 8. This can quickly complete the installation of the snap ring 5, making the installation more convenient and faster, effectively reducing the assembly difficulty and improving production efficiency.

[0032] The main body 1 of the connector has a positioning hole 9. An external structure that is adapted to the positioning hole 9 cooperates with the positioning hole 9, that is, the external structure is located inside the positioning hole 9 to form a positioning, which can effectively improve the stability of the main body 1 of the connector. Preferably, there are two positioning holes 9, which are distributed at intervals.

[0033] The connecting seat body 1 has a triangular reinforcing block 10 at the included angle. The triangular reinforcing block 10 is integrally formed with the connecting seat body 1. Through the supporting effect of the triangular reinforcing block 10, the structural strength at the included angle of the connecting seat body 1 can be effectively ensured, and the stability and reliability of the structure can be improved.

[0034] The main body 1 of the connecting seat is provided with a positioning post 11, and the positioning post 11 is provided with a mounting hole 12. When installing the linear actuator, the positioning post 11 is inserted into the corresponding position of the linear actuator to maintain the relative stability between the main body 1 of the connecting seat and the linear actuator. Finally, the mounting hole 12 is threadedly connected by fasteners such as bolts and screws to form a fixed connection between the main body 1 of the connecting seat and the linear actuator.

[0035] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
