[0029] See also Figure 2 and Figure 3 A roller 31 is disposed on the upper portion of the infusion drug pump sliding assembly 3 , and a roller track 21 matching the roller 31 is formed on the lower portion of the main cross beam 2 .

[0030] See also Figure 2 The first brake mechanism 6 includes a first cylinder 62 and a first solenoid valve 61 fixed in the infusion pump sliding assembly 3. A first brake block 63 is fixed to the axial end of the first cylinder 62. The first solenoid valve 61 switches the air circuit to press the first brake block 63 against the lower surface of the main beam 2 to achieve the braking function.

[0031] See also Figure 4 The infusion drug pump sliding assembly 3 has a connecting shaft a32 extending into the rotating arm 4. The connecting shaft a32 and the outer shell of the infusion drug pump sliding assembly 3 are fixedly connected by threads. The rotating arm 4 and the connecting shaft a32 form a rotatable structure through a bearing a9. The bearing a9 includes two plane bearings, and an intermediate sleeve is arranged between the two plane bearings. In addition, a limiting structure is also provided at the rotational combination position of the rotating arm 4 and the connecting shaft a32. The limiting structure allows the relative rotation angle between the two to be within the range of 360 degrees.

[0032] See also Figures 4 to 6The second brake mechanism 7 includes a second cylinder 72 and a second solenoid valve 71 fixed in the rotating arm 4. A second brake block 73 is fixed to the shaft end of the second cylinder 72. The second solenoid valve 71 switches the air circuit to move the second brake block 73 to limit the rotation of the rotating arm 4 relative to the connecting shaft a32; the second brake mechanism 7 also includes a first gear 78 and a second gear 75. The first gear 78 is fixedly mounted on the connecting shaft a32 and does not rotate. The second gear 75 is arranged inside the rotating arm 4 through a pivot 77. The second gear 75 rotates freely relative to the pivot 77. At the same time, a brake disc 76 that rotates synchronously with the second gear 75 is also arranged on the pivot 77.

The support seat 74 and the second brake block 73 are respectively distributed on the upper and lower sides of the brake disc 76.

[0033] See also Figure 4 The rotating arm 4 has a connecting shaft b41 extending into the liquid medicine pump frame assembly 5. The connecting shaft b41 and the outer shell of the rotating arm 4 are fixedly connected by threads. The liquid medicine pump frame assembly 5 and the connecting shaft b41 form a rotatable structure through a bearing b10. The bearing b10 includes a plane bearing and a ball bearing. An intermediate sleeve is arranged between the plane bearing and the ball bearing. In addition, a limiting structure is also provided at the rotational combination position of the liquid medicine pump frame assembly 5 and the connecting shaft b41. The limiting structure makes the relative rotation angle between the two within the range of 360 degrees.

[0034] See also Figure 7 and Figure 8 There are two damping members 8, which include a damping tube 81 fixedly mounted on the circumference of the connecting shaft b41, a supporting spring 82 built into the damping tube 81, and a damping block 83 supported by the supporting spring 82.

The acting surface of the damping block 83 can be an annular wall surface and pressed against the outer wall surface of the connecting shaft b41 to produce damping by dry friction. Of course, the damping block 83 can also be designed as a spherical structure as shown in the figure.

[0035] During use, after adjusting the position of the medicine liquid pump frame assembly, the purpose of brake locking can be achieved through the first brake mechanism and the second brake mechanism. At the same time, the damping effect of the damping member also limits the rotation of the medicine liquid pump frame assembly, and the overall stability of the medicine liquid pump frame assembly is good.

[0036] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0037] The first solenoid valve and the second solenoid valve are controlled by buttons on the control panel. When the position of the infusion drug pump sliding assembly needs to be adjusted along the length direction of the main beam, the air circuit is switched by controlling the first solenoid valve, so that the first cylinder contracts and the first brake block is separated from the lower surface of the main beam. After the infusion drug pump sliding assembly is manually pushed to the appropriate position, the first cylinder is reset and the first brake mechanism reaches the braking state again.

[0038] When the rotation angle of the rotating arm needs to be adjusted, the air circuit is switched by controlling the second solenoid valve, so that the second cylinder contracts and the second brake block no longer presses the brake disc against the abutment seat, that is, the brake disc can rotate freely (the second gear can rotate synchronously). After manually rotating the rotating arm to a suitable position, the second cylinder is reset and the second brake block presses the brake disc against the abutment seat again, so that the brake disc cannot rotate, that is, the second gear cannot rotate, and thus, the rotating arm cannot rotate.

[0039] When the position of the medicine liquid pump frame assembly needs to be adjusted, the operator only needs to manually rotate it. When the operator no longer applies force, the damping generated by the damping member will keep the medicine liquid pump frame assembly in a stable state.

[0040] That is, after the position is adjusted, the first brake mechanism and the second brake mechanism are both in a braking state, and with the effect of the damping element, the state of the liquid medicine pump frame assembly is very stable.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
