[0032] That is, the infusion set winding and tensioning mechanism provided by the embodiment of the utility model, by setting the guide rod 260 parallel to the top of the sliding member 250, and limiting the movement of the clamping assembly 300 along the extension direction of the sliding member 250 by the slider 210 and the guide block 220, so that the extension and contraction direction of the elastic member 230 is consistent with the direction of the sliding member 250, thereby ensuring the stability of the movement of the clamping assembly 300, and by setting the clamping assembly 300 at the bottom of the fixed platform 100, the device structure is made more compact, thereby solving the technical problems in the prior art that the infusion set winding and tensioning device structure is not compact enough, the force is uneven, and it is easy to get stuck or shake under high-speed operation, which leads to the breakage or damage of the infusion set, thereby ensuring that the infusion set is kept as a whole tight during high-speed winding.

[0033] Specifically, the fixed platform 100 is in the shape of a flat plate and is arranged in the horizontal direction. In this embodiment, the sliding member 250 is a sliding track and is arranged on the fixed platform 100, the slide plate 240 is slidably arranged on the sliding track through the slide block 210, and the guide block 220 is fixed on the slide plate 240 by bolts. In other embodiments of the present application, the sliding member can also be arranged as a sliding groove, and the slide plate 240 is slidably arranged in the sliding groove through the slide block 210; or the sliding member is arranged as a metal optical axis, and the slide plate 240 is slidably arranged on the metal optical axis through the slide block 210. One end of the guide rod 260 is fixed to the fixed platform 100 and is arranged parallel to the sliding track, and the guide rod 260 is arranged directly above the sliding track. The guide block 220 is in an "L" shape as a whole, and a circular hole is arranged on the vertically arranged part thereof, so that the guide block 220 can be sleeved on the guide rod 260. The elastic member 230 is specifically arranged as a spring, which is sleeved on the guide rod 260, and its two ends are respectively in contact with the guide block 220 and the fixed platform 100. When the slide plate 240 moves along the sliding track, the guide block 220 moves accordingly, and then compresses the spring according to the moving distance of the slide plate 240 to obtain tensioning force.

[0034] Furthermore, the infusion pump winding and tensioning device also includes a first driving member 400, which is arranged on the fixed platform 100 and opposite to the guide rod 260. The driving end of the first driving member 400 can abut against the slide plate 240 and drive the slide plate 240 to move along the length direction of the guide rod 260.

[0035] Specifically, in this embodiment, the sliding member 250 is configured as a sliding track, and the first driving member 400 is specifically configured as a cylinder, which is fixed to the fixed platform 100 by bolts, and the first driving member 400 is arranged on one side of the sliding track along the extension direction of the sliding track. The driving end of the first driving member 400, that is, the push rod of the cylinder, can abut against the slide plate 240 and push the slide plate 240 to move. In this way, the slide plate 240 can move along the extension direction of the sliding track, that is, the length direction of the guide rod 260, and then compress the spring, so that the infusion set winding tensioning device enters a tensioning state for the grasped infusion set.

[0036] Furthermore, the infusion pump winding and tensioning device also includes a connecting plate 500, which is arranged on the fixed platform 100 and opposite to the first driving member 400.

The size of the guide hole is larger than the size of the clamping assembly 300. After the clamping assembly 300 is fixed in the guide hole, the remaining cavity of the guide hole can be passed through by the guide plate 120. Therefore, by setting the connecting bracket 600, the clamping assembly 300 can be set at the bottom of the fixed platform 100, making the device structure more compact.

[0040] Preferably, the fixed platform 100 includes a fixed plate 110 and a guide plate 120, the length direction of the guide plate 120 is arranged along the length direction of the guide rod 260, the connecting plate 500 is arranged at one end of the guide plate 120, and the fixed plate 110 is arranged at the other end of the guide plate 120, and the width of the fixed plate 110 is greater than the width of the guide plate 120.

[0041] Specifically, the fixing plate 110 and the guide plate 120 are integrally provided and can be cut from a single plate. The fixing plate 110 is in a square shape as a whole, while the guide plate 120 is in a strip shape as a whole, and the width of the fixing plate 110 is greater than the width of the guide plate 120. In this way, the guide plate 120 can be more easily passed through the guide hole, reducing the structural size; at the same time, the fixing plate 110 can more easily carry the first driving member 400, thereby improving the stability of the device.

[0042] Furthermore, the clamping assembly 300 includes a second driving member 310 and a clamping member 320. The second driving member 310 is fixed to the connecting bracket 600.

[0043] Specifically, the second driving member 310 is configured as a clamping cylinder, which is fixed to the connecting bracket by bolts, and the two clamping members 320 are respectively connected to the two output ends of the clamping cylinder, so that the clamping cylinder can drive the two clamping members 320 to complete the clamping action.

[0044] Preferably, the clamping member 320 includes a clamping arm 321 and a clamping claw 322 . The clamping arm 321 is extended along the direction of the sliding member 250 , and the clamping claw 322 is disposed at one end of the clamping arm 321 away from the second driving member 310 .
