Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 6 The utility model provides a tube diameter measuring device for medical catheter production, comprising a base assembly 1, on which a measuring assembly 2 and a mounting assembly 4 are mounted, two mounting assemblies 4 are provided, and a clamping assembly 3 is mounted on each of the two mounting assemblies 4;

[0027] Among them, the mounting assembly 4 includes a mounting plate 43, the clamping assembly 3 includes an A clamping block 32, a B clamping block 33, a rack 34 and a gear 35, the A clamping block 32 and the B clamping block 33 are both slidably set on the mounting plate 43, a plurality of racks 34 are provided, and the plurality of racks 34 are respectively installed on the A clamping block 32 and the B clamping block 33, and two gears 35 are provided, and the two gears 35 are both installed on the mounting plate 43, and the two gears 35 are respectively meshed with the two racks 34.

[0028] Specifically, after the production of medical catheters is completed, sampling inspection is required to measure whether the specifications of the medical catheters produced in this batch meet the standards. During the inspection, the inner diameter of the medical catheter can be measured to check whether it meets the specifications.

[0029] Furthermore, when measuring, the medical catheter can be inserted into the mounting plate 43 and fixed by the clamping assembly 3 to avoid the catheter from being offset during the measurement, thereby causing inaccurate measurement. After the catheter is stably placed, the measuring assembly 2 can be moved to measure the inner diameter of the catheter to observe whether the catheter meets the specifications. When fixing the catheter, the A clamping block 32 can be moved to drive the two racks 34 installed on the A clamping block 32 to move together (these two racks 34 are moved together). The rack 34 is called the active rack, and when the active rack moves, it drives the two gears 35 to rotate. Since the two racks 34 connected to the B clamping block 33 (these two racks 34 are called follower racks) are also engaged with the gears 35 and the active rack and the follower rack are symmetrically arranged, when the active rack moves, it drives the follower rack to move in the opposite direction, and at this time, the B clamping block 33 and the A clamping block 32 are driven to move relative to each other. At this time, the catheter arranged between the A clamping block 32 and the B clamping block 33 can be clamped, thereby preventing the subsequent catheter from being offset.

[0030] In this embodiment, the two gears 35 and the two racks 34 are symmetrically arranged, an insertion hole is provided on the mounting plate 43, and a clamping groove is provided on the A clamping block 32 and the B clamping block 33.

[0031] Specifically, in order to enable the A clamping block 32 and the B clamping block 33 to remain stable during movement, two gears 35 and four racks 34 are provided, wherein the four racks 34 are respectively meshed with the two gears 35 and connected to the A clamping block 32 and the B clamping block 33, and the two gears 35 are symmetrically arranged, so that the upper and lower ends of the A clamping block 32 and the B clamping block 33 can move relatively stably.

At this time, the B screw rod 36 can be rotated to enable the A clamping block 32 to move, and then the catheter can be clamped.

[0034] In this embodiment, two clamping assemblies 3 are provided, and the two clamping assemblies 3 are symmetrically mounted on the mounting plate 43 .

[0035] Specifically, in order to be able to clamp the catheter in all directions, two clamping assemblies 3 are provided on the mounting plate 43, and the two clamping assemblies 3 are symmetrically arranged, and one clamping assembly 3 clamps the catheter left and right, and the other clamps the catheter up and down.

[0038] In this embodiment, the measuring assembly 2 includes a placement plate 21 and a T-block 22 . The placement plate 21 is mounted on the T-block 22 , and the T-block 22 is slidably disposed in the A limit groove.

[0039] Specifically, during actual use, since catheters of different specifications have different lengths, in order to facilitate subsequent measurements, a T-block 22 is set in the A limit groove, and a placement plate 21 is set on the T-block 22. By moving the T-block 22 and the placement plate 21, the laser emitting device 25 can be driven to move laterally, thereby facilitating subsequent more accurate measurements.

[0040] In this embodiment, the measuring component 2 also includes a moving block A 23, a screw rod A 24, a laser emitting device 25 and a handle 26.

By rotating the handle 26 installed on the A screw rod 24, the A screw rod 24 can be driven to rotate, and then the relative position between the two A moving blocks 23 can be adjusted, so that the relative position between the two laser emitting devices 25 can be adjusted.

[0042] Furthermore, in actual use, a scale may be set between the two laser emitting devices 25 , and during measurement, the distance between the two laser emitting devices 25 may be read to obtain the diameter of the medical catheter.

[0043] In this embodiment, the mounting assembly 4 also includes a C screw rod 41 and a B moving block 42. Two B moving blocks 42 are provided, and the two B moving blocks 42 are respectively installed on the mounting plate 43. The C screw rod 41 is installed in the A rotating hole. The two B moving blocks 42 are both threadedly arranged on the C screw rod 41, and the two B moving blocks 42 are both installed in the B limit groove.

[0044] Specifically, in actual use, in order to be able to clamp medical catheters of different specifications and lengths more stably, a mounting assembly 4 is provided on the base assembly 1, and the relative positions of the two mounting plates 43 can be adjusted through the mounting assembly 4, so that catheters of different lengths can be clamped. When adjusting the positions of the two mounting plates 43, since the mounting plates 43 are mounted on the B moving blocks 42, and the B moving blocks 42 are threadedly arranged on the C screw rod 41, and the two B moving blocks 42 are symmetrically arranged, the relative positions of the two B moving blocks 42 can be changed by rotating the C screw rod 41, and the relative positions of the mounting plates 43 can be changed.

[0045] The working principle and use process of the utility model are as follows: when measuring the inner diameter of the produced medical catheter, the medical catheter can be first inserted into the mounting plate 43, and the medical catheter can be fixed by the clamping assembly 3, so that the two mounting plates 43 and the clamping assembly 3 installed on the mounting plate 43 can clamp and fix both ends of the medical catheter, so as to avoid the deviation of the medical catheter during the measurement, thereby causing a large measurement error. After the medical catheter is fixed, the measuring assembly 2 can be moved according to the length of different medical catheters, and the inner diameter of the catheter can be measured by the measuring assembly 2.
