[0027] The utility model provides the following technical solutions:

[0028] Example 1: Please refer to Figure 1-5 The utility model provides a technical solution: a high-pressure liquid ammonia pump, comprising a base 1, a shock absorbing mechanism 2 is fixedly connected inside the base 1, a support plate 3 is fixedly connected to the top of the shock absorbing mechanism 2, a pump body 4 is fixedly connected to the top of the support plate 3, water pipes 5 are sleeved on the left and right sides of the pump body 4, and an auxiliary fixing mechanism 6 is fixedly connected to the top of the water pipe 5;

When the insertion rod 615 is not subjected to external force, the first spring 618 can drive the insertion rod 615 to move downward through the limiting ring 616, so that the insertion rod 615 can be inserted into the insertion plate 617 to limit the insertion plate 617.

[0033] Example 2: Please refer to Figure 1-5 On the basis of the first embodiment, the auxiliary component 62 further comprises an L-shaped plate 622, the L-shaped plate 622 is fixedly connected to the top of the water pipe 5, the front and rear sides of the L-shaped plate 622 are fixedly connected to a limiting plate 623, the limiting plate 623 is internally slidably connected to a limiting rod 624, the back end of the limiting rod 624 is fixedly connected to a connecting block 627, the bottom of the connecting block 627 is fixedly connected to a sealing plate 621, and the bottom of the sealing plate 621 fits with the top of the water pipe 5.

[0034] Furthermore, a threaded rod 625 is rotatably connected to the top of the connecting block 627. The threaded rod 625 is threadedly connected to the inside of the L-shaped plate 622.

[0035] Example 3: Please refer to Figure 1-5 On the basis of the first and second embodiments, the shock absorbing mechanism 2 further comprises a load-bearing plate 21, the load-bearing plate 21 is fixedly connected to the bottom of the support plate 3, a telescopic rod 23 is fixedly connected to the bottom of the load-bearing plate 21, the bottom of the telescopic rod 23 is fixedly connected to the bottom of the base 1, sliders 26 are fixedly connected to the left and right sides of the load-bearing plate 21, the sliders 26 are slidably connected to the inside of the base 1, a second damping plate 25 is fixedly connected to the bottom of the load-bearing plate 21, a first damping plate 22 is arranged on the right side of the second damping plate 25, the first damping plate 22 is fixedly connected to the bottom of the base 1, and the left side of the first damping plate 22 rubs against the second damping plate 25.

The second spring 24 can drive the load-bearing plate 21 to move upward quickly, so that the device can return to its original position, achieving a buffering and shock-absorbing effect, so that the connection between the pump body 4 and the water pipe 5 will not easily loosen.

[0037] In actual operation, when the device is used, when the water pipe 5 needs to be installed on the left and right sides of the pump body 4, the pull plate 613 is pulled upward so that the pull plate 613 can drive the plug rod 615 to move upward, and the plug rod 615 can squeeze the first spring 618 through the limit ring 616 to insert the plug plate 617 into the arc plate 612. When the plug plate 617 penetrates the arc plate 612, the force on the pull plate 613 is released so that the plug rod 615 can be inserted into the plug plate 617, and the plug plate 617 is limited to prevent the water pipe 5 from loosening and making the water pipe 5 and the pump body 4 more tightly connected. When the water pipe 5 is used for a long time and becomes loose at the connection with the pump body 4, the water pipe 5 cannot be replaced in time during use. The plate 626 drives the threaded rod 625 to rotate, so that the threaded rod 625 can drive the connecting block 627 to move downward, so that the connecting block 627 can drive the sealing plate 621 to move downward, so that the bottom of the sealing plate 621 can fit together with the connection between the water pipe 5 and the pump body 4, and seal the connection. When the pump body 4 is hit by an external force, the pump body 4 can drive the load-bearing plate 21 to move downward, so that the load-bearing plate 21 can squeeze the telescopic rod 23 and the second spring 24, and the load-bearing plate 21 can drive the second damping plate 25 and the first damping plate 22 to rub against each other. Through the action of the second spring 24, the pump body 4 can quickly return to its original position, so that when the device is hit by an external force, the shaking amplitude is reduced, and the connection between the water pipe 5 and the pump body 4 is not easy to loosen.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
