[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] For reference Figure 1-3 The utility model is described as follows:

[0024] Embodiment 1: A valve core retaining ring structure on a valve body of a clutch booster comprises a valve body 1 , in which a mounting shaft hole 2 is arranged, and the mounting shaft hole 2 is arranged through both sides of the valve body 1 .

[0025] A valve core 3 and a stop sleeve 4 are arranged in the valve body 1. The valve core 3 and the stop sleeve 4 are adapted to be slidably connected with the mounting shaft hole 2, ensuring that the valve core and the stop sleeve can move smoothly and accurately during operation, reducing jamming and deviation. A sealing ring 10 is arranged between the stop sleeve 4 and the side wall of the mounting shaft hole 2. The setting of the sealing ring 10 enhances the sealing between the stop sleeve 4 and the mounting shaft hole 2, prevents gas or liquid leakage, and ensures the working pressure and stability of the system.

[0026] The stopper sleeve 4 is arranged near the open end of one end of the mounting shaft hole 2, and a spring 5 is arranged between the stopper sleeve 4 and the valve core 3. The spring 5 is located between the stopper sleeve 4 and the valve core 3, and can provide a certain elastic restoring force for the movement of the valve core and the stopper sleeve, which is helpful for the resetting and stability of the valve core and the stopper sleeve during the working process. The open end of one end of the mounting shaft hole 2 is provided with an open retaining ring 6 for limiting the escape of the stopper sleeve 4. An annular connecting groove is arranged on the side wall of the mounting shaft hole 2, and the open retaining ring 6 is connected in the connecting groove. The open retaining ring 6 limits the escape of the stopper sleeve 4 from one end of the mounting shaft hole 2, ensuring that the stopper sleeve moves within the working range, and preventing it from accidentally falling off and affecting the normal operation of the system.

[0027] An annular limiting ring 11 is provided on the inner side wall of the other end of the mounting shaft hole 2, and one end of the valve core 3 abuts against the limiting ring 11, and the limiting ring 11 limits the movement range of the valve core 3 in the mounting shaft hole 2. The valve core 3 is provided with holes running through both ends of its axial direction, and the holes are used for the circulation of gas or liquid to realize the corresponding control function.

[0028] The outer end of the stopper sleeve 4 is provided with a stud 7 extending outward, and an adjusting retaining ring 8 is threadedly connected to the stud 7. The adjusting retaining ring 8 is located on the inner side of the open retaining ring 6, and the open retaining ring 6 can limit the escape of the adjusting retaining ring 8. The position of the stopper sleeve 4 is changed by adjusting the position of the retaining ring 8 on the stud 7, and then the degree of compression of the spring 5 is adjusted, so that the precise control of the spring elastic force is achieved.

[0029] The adjusting retaining ring 8 is in the shape of a ring, and the adjusting retaining ring 8 is designed in the shape of a ring, which has good symmetry and stability. The adjusting retaining ring 8 is provided with an operating hole 9, and at least two operating holes 9 are provided. The operating holes 9 are arranged at intervals in the circumferential direction of the adjusting retaining ring 8, and the adjusting retaining ring 8 can be operated to rotate through the operating holes 9. The multiple operating holes 9 provide multiple operating positions and angles for selection, which is convenient for operators to insert tools into the operating holes 9 to rotate the adjusting retaining ring 8 in different spaces and positions.

[0030] The stud 7 and the stopper sleeve 4 can be pressed first, and then the adjusting retaining ring 8 can be rotated to adjust the position. Pressing the stud 7 and the stopper sleeve 4 can pre-compress the spring 5, reduce the reaction force of the spring during the adjustment process, and make it easier and smoother to rotate the adjusting retaining ring 8. In this way, the position of the adjusting retaining ring 8 can be controlled more accurately, avoiding inaccurate adjustment or difficult operation due to the elastic force of the spring. If the adjusting retaining ring 8 is directly rotated without pressing it in advance, the elastic force of the spring 5 may make it difficult to rotate the adjusting retaining ring 8, or it may jump during the rotation process, affecting the accuracy and stability of the adjustment.

[0031] A connecting shaft hole 12 is provided in the stopper sleeve 4, and the other end of the valve core 3 is adapted to be slidably connected with the connecting shaft hole 12, and a sealing ring 2 13 is provided between the valve core 3 and the side wall of the connecting shaft hole 12. The connecting shaft hole 12 in the stopper sleeve 4 is adapted to be slidably connected with the other end of the valve core 3. This design ensures the stability and linearity of the valve core 3 during the movement process, and reduces the possible deviation or jamming of the valve core 3. The provision of the sealing ring 2 13 effectively enhances the sealing between the valve core 3 and the connecting shaft hole 12, prevents liquid or gas from leaking from this connection, thereby ensuring the stability of the internal pressure of the clutch booster and normal operation.

[0032] Core invention points: stud 7 and adjusting retaining ring 8.

[0033] First, the stud 7 provides basic support and guidance for the installation and adjustment of the adjusting retaining ring 8. Its stable structure and precise thread enable the adjusting retaining ring 8 to be accurately adjusted along a predetermined path.

[0034] The adjusting retaining ring 8 is the core component for realizing the precise adjustment function. By rotating and moving on the stud 7, it can effectively change the position of the retaining sleeve 4, thereby accurately controlling the compression degree of the spring 5.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
