The invention belongs to the technical field of vane pumps and discloses a high-speed common rail vane pump. The high-speed common rail vane pump includes a stator, a rotor, an end cover and a bottom plate. The rotor is located in an eccentric hole opened on the stator. The outer wall of the rotor is provided with four vane mechanisms arranged in a ring with the center of the rotor as a reference. , the bottom plate and the end cover are symmetrically attached to the upper and lower surfaces of the stator respectively. The high-speed common rail vane pump improves the vane. By opening an arc-shaped load-bearing groove on the vane and cooperating with the oil supply of the first and second ring grooves when the vane pump is running, the high-pressure oil can be used to push the vane, so that When the rotor rotates at high speed, the vane can pop out quickly, which improves the high-speed performance of the vane pump, keeps the contact between the vane and the wall of the eccentric hole, and improves the oil delivery efficiency of the vane pump.

The invention provides a multifunctional movable retaining wall test device comprising a model box and a movable retaining wall. Displacement control screw mechanisms are arranged on the upper and lower parts of the front end of a model box frame. At least one row of auxiliary bearing screw mechanisms is arranged in the middle of the front end of the model box frame. Bearing seats are arranged in a pitch rotation way at positions of the movable retaining wall corresponding to through holes. A bearing used for inserting and fixing a corresponding displacement control screw is arranged inside each bearing seat. Grooves used for being in movable insertion fit with auxiliary bearing screws are arranged at positions of the movable retaining wall corresponding to auxiliary bearing nuts. According to the multifunctional movable retaining wall test device of the invention, through multi-stage alternate fine adjustment, namely, adjusting the auxiliary bearing screws first and then adjusting the displacement control screws and repeating the steps, test of different displacements and displacement modes needed is realized. The multifunctional movable retaining wall test device can realize active and passive earth pressure test, and has the advantages of simple structure, low cost, multiple functions, and good use effect.

The invention discloses a spring retraction device of a 3D (three-dimensional) movement. The spring retraction device comprises a connecting sheet, an accommodating cavity, a spring and a push rod, wherein the connecting sheet comprises a top sheet and a side sheet which are integrally formed, and the top sheet and the side sheet form an L-shaped structure; the accommodating cavity is connected onto the top sheet; the spring is located in the accommodating cavity, and a through hole is formed in the top sheet; the push rod extends into the accommodating cavity, a bulged shoulder propped against the bottom of the spring is arranged on the push rod, and the top of the push rod can extend out of the through hole after the spring is extruded by the push rod. The spring retraction device for the 3D movement has the benefits as follows: when the spring retraction device is applied to the 3D movement of an electric massage chair and an outer motor drives the push rod to move up and down, the push rod can drive the whole accommodating cavity to move, the spring is arranged in the accommodating cavity, so that when the motor drives the whole spring retraction device to move, the movement speed becomes slower under the action of elastic buffer of the spring, accordingly, the whole 3D movement moves in a more balanced manner, the stiff feeling of a user during using of the spring retraction device is reduced, and the user experience can be effectively improved.
