[0028] Reference Figures 1-3 This utility model provides a fixed fixture for testing a hydraulic pump, comprising:

[0029] The main unit 100 includes a substrate 101, which is arranged in a square structure. A pump body 102 is provided on the substrate 101. The auxiliary equipment components can be installed through the distribution of the substrate 101, and the pump body 102 meets the testing needs.

[0030] The moving unit 200 includes two vertical plates 201, both of which are fixedly connected to the base plate 101. The two vertical plates 201 are rotatably connected to a bidirectional lead screw 202 on their sides that are close to each other. One end of the bidirectional lead screw 202 passes through one of the vertical plates 201 and is fixedly connected to a knob 203. The two arms of the bidirectional lead screw 202 are threadedly connected to lower plates 204. The two lower plates 204 are provided with a fixing component 205. The knob 203 can drive the bidirectional lead screw 202 to rotate, so that the two lower plates 204 are close to each other or far apart, which facilitates the adjustment of the fixed position, thereby positioning and fixing the pump body 102, which is beneficial for the use of the fixing fixture for the pump body 102.

[0031] The fixing component 205 includes four guide rods 205a, which are fixedly connected to the corresponding lower plates 204. Upper plates 205b are slidably connected to each pair of corresponding guide rods 205a. Springs 205c are fitted onto the arms of each of the four guide rods 205a. Baffles 205d are fixedly connected to the sides of the two upper plates 205b away from the base plate 101. Handles 205e are fixedly connected to the two baffles 205d. The upper plates 205b are kept in contact with the lower plates 204 by the force of the springs 205c, and the baffles 205d restrict the sides of the pump body 102, enhancing the fixing effect of the pump body 102 and greatly reducing the shaking generated during testing. Conversely, the handles 205e facilitate the removal of the pump body 102.

[0032] Furthermore, each of the four guide rods 205a has a pull block fixedly connected to its top end, and the two ends of the four springs 205c are fixedly connected to the corresponding upper plate 205b and pull block, respectively. The two lower plates 204 and the two upper plates 205b are all arranged in an arc shape, which can guide and limit the translation of the upper plate 205b through the guide rods 205a, ensuring that the equipment clamps the pump body 102 stably. The arc shape of the lower plates 204 and the upper plates 205b also helps to better fit the pump body 102.

[0033] Furthermore, anti-slip pads 206 are fixedly connected to the inner walls of the two lower plates 204 and the two upper plates 205b. The multiple anti-slip pads 206 are in close contact with the pump body 102, and can make elastic contact with the pump body 102 through the anti-slip pads 206, so as to avoid damage to the surface of the pump body 102 caused by fixing. At the same time, the anti-slip effect enhances the fixed connection of the pump body 102.

[0034] Furthermore, two grooves 207 are formed on the side of the substrate 101 near the pump body 102. Two sliders 208 are slidably connected in the two grooves 207 respectively. The four sliders 208 are fixedly connected to the corresponding lower plate 204 respectively. The movement of the lower plate 204 can be guided and restricted by the cooperation between the grooves 207 and the sliders 208, thereby improving the stability of the translation of the lower plate 204.

[0035] Furthermore, two stabilizing plates 209 are fixedly connected to the side of the substrate 101 away from the pump body 102. Multiple mounting plates 210 are fixedly connected to each of the two stabilizing plates 209. The stabilizing plates 209 can enhance the support of the substrate 101, and the mounting plates 210 can assist in the installation and use of equipment, making it easier for the user to operate.

[0036] During use, the knob 203 drives the bidirectional lead screw 202 to rotate, causing the lower plates 204 on both sides to move closer or further apart, which facilitates the adjustment and fixing of the pump body 102. This is beneficial for the use of the fixing fixture for the pump body 102. The upper plate 205b is always in contact with the lower plate 204 by the force of the spring 205c. The baffle 205d restricts the two sides of the pump body 102, which strengthens the fixing effect of the pump body 102 and greatly reduces the shaking generated by the pump body 102 during testing. Conversely, the handle 205e facilitates the removal of the pump body 102.

[0037] The anti-slip pad 206 makes elastic contact with the pump body 102, preventing damage to the surface of the pump body 102 caused by fixing. The sliding groove 207 and the slider 208 cooperate to guide and restrict the movement of the lower plate 204, improving the stability of the translation of the lower plate 204.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
