Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medical cable sheath pulling-back device. Background Art

[0002] During the processing of medical cables, it is required that the port of the cable shielding layer cannot be exposed outside the outer sheath. Due to the special requirements of some medical cables, the cable sheath and shielding layer are made of softer materials. When stripping the wire, the shielding layer is easily exposed at the outer sheath. Therefore, when processing the shielding layer of the cable, it is necessary to pull the cable sheath back 6mm to 8mm and then trim the shielding layer. After trimming the shielding layer, pull the cable sheath back forward to cover the shielding layer to solve the problem of exposed shielding layer.

[0003] In the related art, operators generally use manual pulling back of the outer sheath, and manually hold the cable pulling tool to clamp the cable to cover the outer sheath with the shielding layer. This is not only inefficient, but also causes blisters on the fingers and severe limb fatigue after long-term operation. Utility Model Content

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0020] Please refer to Figure 1-3 . The utility model provides a medical cable outer sheath retraction device. The medical cable outer sheath retraction device includes a clamping mechanism 1, a retraction mechanism 3 and a mechanism reset assembly 5 placed in sequence along a first direction Y. The cable 10 is placed in the same direction as the first direction Y. The cable 10 is clamped in the clamping mechanism 1 and the retraction mechanism 3. Because the cut end of the cable is in a state where the shielding layer 101 is long and the outer sheath 103 is short before the cable is retracted, the cut end of the cable is clamped on the mechanism reset assembly 5 and the port of the outer sheath 103 is in contact with the mechanism reset assembly 5. The retraction mechanism 3 pulls the cable outer sheath 103 to move along the first direction Y and is stretched, so that the outer sheath 103 at the cut end of the cable 10 is stretched and pushes the mechanism reset assembly 5 to move along the first direction Y, thereby controlling the reset of the clamping mechanism 1 and the retraction mechanism 3. Therefore, the cable is clamped by the provided clamping mechanism 1, and the outer sheath 103 is pulled back by the provided pulling back mechanism 3 to realize the processing technology of pulling back the outer sheath 103 of the cable, and the setting of the mechanism reset component 5 enables the outer sheath 103 of the cable to achieve the purpose of resetting each mechanism during the pulling back process. The mechanism reset component 5 utilizes the change of the outer sheath 103 of the cable itself after being stretched to trigger the action and achieve the purpose of resetting each mechanism to meet the cyclic processing, thereby realizing the fully automated processing of pulling back the outer sheath 103 of the cable, and greatly improving the production efficiency.

[0021] Specifically, in this embodiment, the clamping mechanism 1 includes a positioning seat 11, a clamping block 13 having one end inserted into the positioning seat 11, and a clamping driver 15 connected to the other end of the clamping block 13 for driving the clamping block 13 to move toward the positioning seat 11. The cable is clamped between the positioning seat 11 and the clamping block 13. Driven by the clamping driver 15, the clamping block 13 reciprocates to clamp and release the cable.

[0022] Specifically, the positioning seat 11 is L-shaped, with a limiting hole 17 extending through the center of the positioning seat 11 and extending along two opposite sides thereof. A portion of the clamping block 13 is inserted into the limiting hole 17, while the other portion protrudes upward and is flush with the top of the positioning seat 11, forming a clamping space 19 in which the cable is placed. The clamping block 13 moves along the limiting hole 17 under the control of the clamping driver 15, and the clamping space is reduced by the clamping driver 15 to clamp the cable. Therefore, the positioning seat 11 and the clamping block 13 improve the flexibility and stability of the structure.

[0023] Furthermore, the shape of the limiting hole 17 matches the shape of the portion of the clamping block 13 inserted into the positioning seat 11 to improve the adaptability of the structure. The limiting hole 17 runs through both sides and is square in shape. One end of the clamping block 13 is inserted into the limiting hole 17 and is driven by the clamping driver 15 to reciprocate along the limiting hole 17.

[0024] Specifically, in this embodiment, the clamping actuator 15 is a pneumatic cylinder. The clamping actuator 15 is connected to a control box. When an operator presses a switch, the clamping actuator 15 actuates to push the clamping block 13 toward the positioning seat 11 to clamp the cable. When the clamping actuator 15 resets, the clamping block 13 releases the cable.

[0025] like Figure 2 and Figure 3 As shown, specifically, the pulling back mechanism 3 includes a drag block 31, a pulling back driver 33 connected to the drag block 31 for driving the drag block 31 to move along the first direction, and a left clamping component 35 and a right clamping component 37 installed on the drag block 31 and arranged opposite to each other on the left and right. The cable is placed between the left clamping component 35 and the right clamping component 37. The left clamping component 35 and the right clamping component 37 can both move back and forth in the direction of the cable to clamp the cable or release the cable. The operator presses the switch, and when the clamping driver 15 moves, the left clamping component 35 and the right clamping component 37 also move at the same time to clamp the cable. Subsequently, the pulling back driver 33 drives the drag block 31 to move along the first direction Y to stretch the outer jacket 103.

[0026] Furthermore, the left clamping assembly 35 and the right clamping assembly 37 have the same structure. Specifically, each includes a cable clamping block 371 and a clamping actuator 373 connected to the cable clamping block 371 for driving the movement of the cable clamping block 371. A cable is placed between the two cable clamping blocks 371. Driven by the clamping actuator, both cable clamping blocks 371 simultaneously move toward the cable to clamp it. After clamping, the pull-back actuator 33 drives the drag block 31 in the first direction Y, stretching the outer sheath 103 of the cable. The stretched outer sheath 103 pushes the reset assembly 5 upward. Once the reset assembly 5 is actuated, it resets the connected clamping actuator and pull-back actuator 33. After the operator removes the retracted cable from the device, a new cable to be retracted is inserted, and the next cable retraction process begins. This cycle repeats to achieve processing.

[0027] Specifically, in this embodiment, the clamping driver 373 and the pulling driver 33 are both cylinders.

[0028] Specifically, in this embodiment, the mechanism reset assembly 5 includes a reset plate 51, a tilting push plate 53 and a micro switch 55. The tilting push plate 53 is installed between the reset plate 51 and the micro switch 55, and one end is connected to the reset plate 51 and the other end is abutted against the micro switch 55. The micro switch 55 is also electrically connected to the clamping mechanism 1 and the pulling back mechanism 3.

[0029] Furthermore, the reset plate 51 is L-shaped, with a V-shaped slot at its end. The shielding layer 101 at the cutout end of the cable is retained within the slot, and the end of the cable sheath 103 abuts the bottom of the reset plate 51. When the cable sheath 103 is stretched, it pushes the reset plate 51 upward, lifting the lift plate 53 and pushing the microswitch 55. Upon receiving the actuation, the microswitch 55 determines that the pullback action is complete. Upon receiving the trigger signal from the microswitch, the master controller controls the individual cylinders to reset.

[0030] The medical cable sheath 103 retraction device provided by the embodiment of the present invention clamps the cable through the provided clamping mechanism 1, and pulls back the sheath 103 through the provided retraction mechanism 3 to realize the processing technology of retracting the cable sheath 103. The setting of the mechanism reset component 5 enables the cable sheath 103 to achieve the purpose of resetting each mechanism during the retraction process. The mechanism reset component 5 utilizes the change of the cable sheath 103 itself after being stretched to trigger the action and achieve the purpose of resetting each mechanism to meet the cyclic processing, thereby realizing the fully automated processing of retracting the cable sheath 103 and greatly improving the production efficiency.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
