[0028] See also Figure 1-Figure 3 A multi-stage pump body 110 is disposed on the surface of the support seat 100 , and a support plate 120 is disposed at the bottom of the support seat 100 .

[0029] In this embodiment, the surface of the support seat 100 is rotatably connected with a transmission member 130, and the surface of the transmission member 130 is threadedly sleeved with two moving blocks 140. The tops of the two moving blocks 140 are connected with positioning blocks 141. The positioning blocks 141 are fitted with the upper surface of the support seat 100, and the two positioning blocks 141 are respectively fitted with the two sides of the multi-stage pump body 110. In specific implementation, the multi-stage pump body 110 is placed on the support seat 100, and the transmission member 130 is rotated to drive the two moving blocks 140 to move relative to each other, thereby driving the two positioning blocks 141 along the support seat 100.

[0030] A placement groove 150 is opened in the support seat 100, and the two moving blocks 140 are both in contact with the inner wall of the placement groove 150. The double-headed screw 131 is located in the placement groove 150. In a specific implementation, when the double-headed screw 131 rotates, the two moving blocks 140 can move relative to each other along the inner wall of the placement groove 150, which is beneficial to improve the stability of the moving blocks 140 during the movement process; a shock absorber 121 is connected between the support seat 100 and the support plate 120, and a plurality of shock absorbers 121 are provided. In a specific implementation, multiple shock absorbers 121 are provided between the support seat 100 and the support plate 120, which is beneficial to improve the shock absorbing and buffering effect of the device.

[0031] See also Figure 1-Figure 4, two shock absorbing devices 200 are arranged on the lower surface of the support seat 100, and the shock absorbing device 200 includes two fixed blocks 210 and a rod body 220, the two fixed blocks 210 are installed on the upper surface of the support plate 120, the rod body 220 is installed between the two fixed blocks 210, and two hinge seats 230 are slidingly sleeved on the surface of the rod body 220, a first spring 240 is arranged between the two hinge seats 230 and the corresponding fixed blocks 210, and the tops of the two hinge seats 230 are rotatably connected with a connecting rod 250, and the connecting rod 250 is rotatably connected to the lower surface of the support seat 100. In a specific implementation, when the multistage pump itself When the body 110 is vibrated, the support seat 100 will move downward. Since the two ends of the connecting rod 250 are rotatably connected to the support seat 100 and the articulated seat 230 respectively, the support seat 100 can drive the connecting rod 250 to rotate slightly, thereby driving the two articulated seats 230 to move away from each other along the surface of the rod body 220 on the fixed block 210, which is beneficial to the stability of the two articulated seats 230 during the movement. The two articulated seats 230 will compress the first springs 240 connected to them accordingly, which is beneficial to the shock-absorbing and buffering effect on the multi-stage pump body 110, and reduces the possibility of poor buffering effect when the multi-stage pump works on the ground.

[0032] In this embodiment, the lower surface of the hinge seat 230 is connected with a wear-resistant pad 231, and the wear-resistant pad 231 is in contact with the upper surface of the support plate 120. In a specific implementation, when the connecting rod 250 rotates slightly, the wear-resistant pad 231 on the lower surface of the hinge seat 230 can move along the upper surface of the support plate 120, thereby reducing the possibility of wear caused by long-term contact between the hinge seat 230 and the upper surface of the support plate 120. It should be noted that the wear-resistant pad 231 can be made of rubber or silicone. A wear-resistant ring 232 is connected inside the hinge seat 230. The wear-resistant ring 232 is slidably mounted on the surface of the rod body 220, and the first spring 240 is mounted on the surface of the rod body 220.

[0035] Specifically, the working principle of the base structure of the vertical stamping multi-stage pump is as follows: when in use, the multi-stage pump body 110 is placed on the support seat 100, and the double-headed screw 131 can be driven to rotate by turning the knob 132, so that the two moving blocks 140 move relatively along the inside of the placement groove 150, which is beneficial to the stability of the moving block 140 during the movement, and the moving block 140 will drive the positioning block 141 connected to it to move relatively, so that the two positioning blocks 141 fix the multi-stage pump body 110, which is beneficial to the stability of the multi-stage pump body 110 on the support seat 100, because the two ends of the connecting rod 250 are respectively connected to the connecting seat 160 on the lower surface of the support seat 100 It is rotatably connected to the articulated seat 230. When the vertical stamping multi-stage pump is vibrated, it can drive the connecting rod 250 to rotate slightly, thereby driving the two articulated seats 230 to move away from each other along the surface of the rod body 220 on the surface of the fixed block 210, which is beneficial to the stability of the two articulated seats 230 during the movement. The articulated seat 230 will compress the first spring 240 corresponding to it, which is beneficial to the shock absorption effect on the multi-stage pump body 110, and reduce the possibility of poor buffering effect when the multi-stage pump works on the ground.
