Description

Technical Field

[0001] The utility model belongs to the technical field of cold shrink tube processing, and in particular relates to a limiting mechanism used for the production and processing of cold shrink tubes. Background Art

[0002] Cold shrink tubing generally refers to cold shrink cable accessories. Cold shrink cable accessories are made of elastic materials that are injection-vulcanized in the factory, and then expanded and lined with plastic spiral supports to form components of various cable accessories. Because it relies on elastic retraction force at room temperature, unlike heat shrink cable accessories that need to be heated and shrunk by fire, it is commonly known as cold shrink tubing.

[0003] Chinese patent CN220742139U discloses a limiting device for processing cold shrink tubes, which relates to the technical field of cold shrink tube processing equipment. A limiting device for processing cold shrink tubes includes a frame, a workbench, a cold shrink device, a clamping device, an extended support device, and a supporting cross plate. The top surface of the frame is fixedly installed with a workbench, and the top surface of the workbench is detachably installed with the cold shrink device, the clamping device, the extended support device, and the supporting cross plate from left to right, and the cold shrink device, the clamping device, the extended support device, and the supporting cross plate are arranged side by side horizontally. The extended support device is located at the right bottom of the clamping device, and the end of the extended support device away from the clamping device is detachably installed on the right top of the supporting cross plate.

[0004] During the processing of the cold shrink tube, the cold shrink tube needs to be limited. The existing devices mostly use direct clamping type limiting, which makes it difficult to match the length of the cold shrink tube. In the above document, the two ends of the cold shrink are matched and pressed and supported by the provided clamping device and the extended support device, but the cold shrink tube is fixed by the lower pressing block and the upper pressing block. The size of the semicircular holes on the lower pressing block and the upper pressing block cannot be adjusted, and only cold shrink tubes of a single size can be fixed, which has certain limitations.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] In response to the problems in the related art, the present invention proposes a limiting mechanism for the production and processing of cold shrink tubes to overcome the above-mentioned technical problems existing in the existing related art.

[0008] The utility model is a limiting mechanism for the production and processing of cold shrink tubes, comprising a workbench, a first bearing plate and a large bracket being provided on the top of the workbench, a first electric push rod being fixedly connected to the top of the large bracket, a movable end of the first electric push rod being fixedly connected to the second bearing plate, adjustment components being provided inside the first bearing plate and the second bearing plate, a clamping plate being rotatably connected to the outer surfaces of the first bearing plate and the second bearing plate, a displacement component being provided on the top of the workbench, and a lifting component being fixedly connected to the top of the displacement component.

[0009] Furthermore, the adjustment assembly includes a first screw, the outer surface of the first screw is threadedly connected to a sliding seat, the outer surface of the sliding seat is rotatably connected to a pulley, a first sliding groove is opened on the top of the first supporting plate, the first screw is rotatably connected to the inside of the first sliding groove, the sliding seat is slidably connected to the inside of the first sliding groove, and the clamping plate is overlapped on the outer surface of the pulley.

[0011] Furthermore, the lifting assembly includes a second electric push rod, the second electric push rod is fixedly connected to the top of the slider, and the movable end of the second electric push rod is fixedly connected to a placement seat.

[0012] Furthermore, a pin is fixedly connected to the outer surface of the clamping plate, a torsion spring is fixedly connected to the interior of the clamping plate, the torsion spring is fixedly connected to the first bearing plate, and the torsion spring is sleeved on the outer surface of the pin.

[0013] Furthermore, the ends of the first screw and the second screw are both fixedly connected with hand wheels.

[0014] Furthermore, the bottom of the workbench is fixedly connected with supporting legs.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model connects the adjustment assembly and the clamping plate. When the adjustment assemblies are close to each other, the adjustment assembly pushes the clamping plate to rotate inward at the same time, so that the clamping plates are close to each other, thereby fixing the smaller cold shrink tube. When the adjustment assemblies are away from each other, the clamping plate on the adjustment assembly rotates downward, so that the clamping plates are away from each other. At this time, the larger cold shrink tube can be fixed. When in use, it can be adjusted according to the size of the cold shrink tube, which is more flexible to use.

[0017] 2. The utility model connects the pulley and the clamping plate. The first screw drives the sliding seat and the pulley to move. When the pulleys approach each other, the pulley can push the clamping plate to rotate around the pin shaft. At this time, the clamping plate rotates inward at the same time. The clamping plate can clamp and fix smaller cold shrink tubes. When the first screw is reversed, the first screw drives the pulleys away from each other, and the clamping plate reverses along the pulley. The clamping plates move away from each other. At this time, larger cold shrink tubes can be fixed. It can be adjusted according to actual conditions during use, and it is more flexible to use.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figures 1-6 As shown, the utility model is a limiting mechanism for the production and processing of cold shrink tubes, including a workbench 1, a first supporting plate 2 and a large bracket 3 are provided on the top of the workbench 1, a first electric push rod 4 is fixedly connected to the top of the large bracket 3, a movable end of the first electric push rod 4 is fixedly connected to the second supporting plate 5, an adjustment component 6 is provided inside the first supporting plate 2 and the second supporting plate 5, a clamping plate 7 is rotatably connected to the outer surface of the first supporting plate 2 and the second supporting plate 5, a displacement component 8 is provided on the top of the workbench 1, and a lifting component 9 is fixedly connected to the top of the displacement component 8.

[0031] There are two groups of displacement components 8 and lifting components 9.

[0032] Place the cold shrink tube between the clamping plates 7, and the adjusting component 6 drives the clamping plates 7 to rotate. When the size of the cold shrink tube is small, the adjusting component 6 pushes the clamping plates 7 closer to each other, and then the first electric push rod 4 pushes the second supporting plate 5 down, so that the clamping plates 7 on the second supporting plate 5 cooperate with the clamping plates 7 on the first supporting plate 2, so that the smaller cold shrink tube can be clamped and fixed. When the size of the cold shrink tube is large, the adjusting component 6 drives the clamping plates 7 away from each other. When the position of the cold shrink tube needs to be adjusted, the lifting component 9 pushes the cold shrink tube upward and separates it from the clamping plate 7, and then the displacement component 8 drives the lifting component 9 and the cold shrink tube to move.

[0033] The utility model connects the adjusting assembly 6 and the clamping plate 7. When the adjusting assemblies 6 are close to each other, the adjusting assembly 6 pushes the clamping plate 7 to rotate inward at the same time, so that the clamping plates 7 are close to each other, thereby fixing the cold shrink tube with a smaller size. When the adjusting assemblies 6 are away from each other, the clamping plates 7 on the adjusting assembly 6 rotate downward, so that the clamping plates 7 are away from each other. At this time, the cold shrink tube with a larger size can be fixed. When in use, it can be adjusted according to the size of the cold shrink tube, which is more flexible to use.

[0034] In one embodiment, for the above-mentioned adjustment component 6, the adjustment component 6 includes a first screw 601, the outer surface of the first screw 601 is threadedly connected to a sliding seat 602, the outer surface of the sliding seat 602 is rotatably connected to a pulley 603, a first sliding groove 604 is opened on the top of the first supporting plate 2, the first screw 601 is rotatably connected to the inside of the first sliding groove 604, the sliding seat 602 is slidably connected to the inside of the first sliding groove 604, and the clamping plate 7 is overlapped on the outer surface of the pulley 603.

[0035] The first screw 601 is rotated, and the first screw 601 drives the sliding seat 602, and the sliding seat 602 moves along the first sliding groove 604. The sliding seat 602 pushes the clamping plate 7 to rotate through the pulley 603, so that the clamping plates 7 are close to each other to clamp and fix the smaller shrink tubes. When the sliding seats 602 move away from each other, the clamping plates 7 also move away from each other, and can fix the larger shrink tubes.

[0036] In one embodiment, for the above-mentioned displacement assembly 8, the displacement assembly 8 includes a second screw 801, the outer surface of the second screw 801 is threadedly connected to a slider 802, a second slide groove 803 is opened on the top of the workbench 1, the second screw 801 is rotatably connected to the inside of the second slide groove 803, and the slider 802 is slidably connected to the inside of the second slide groove 803.

[0037] Rotate the second screw 801, the second screw 801 drives the slider 802, the slider 802 moves along the second slide groove 803, the slider 802 drives the lifting assembly 9 to move, and then the cold shrink tube on the lifting assembly 9 moves synchronously, achieving the purpose of changing the position of the cold shrink tube.

[0038] In one embodiment, for the above-mentioned lifting assembly 9, the lifting assembly 9 includes a second electric push rod 901, the second electric push rod 901 is fixedly connected to the top of the slider 802, and the movable end of the second electric push rod 901 is fixedly connected to the placement seat 902.

[0039] Start the second electric push rod 901, which drives the placement seat 902 to move upward. The placement seat 902 lifts the cold shrink tube, so that the cold shrink tube is separated from the clamping plate 7. At this time, the slider 802 drives the second electric push rod 901 to move, and the second electric push rod 901 drives the square seat 902 and the cold shrink tube to move, which can change the position of the cold shrink tube. After the adjustment is completed, the second electric push rod 901 drives the placement seat 902 to descend, and then the cold shrink tube is placed back on the clamping plate 7.

[0040] In one embodiment, for the above-mentioned clamping plate 7, the outer surface of the clamping plate 7 is fixedly connected to a pin shaft 10, and the inside of the clamping plate 7 is fixedly connected to a torsion spring 11, and the torsion spring 11 is fixedly connected to the first supporting plate 2, and the torsion spring 11 is sleeved on the outer surface of the pin shaft 10.

[0041] The clamping plate 7 rotates through the pin 10, and when the clamping plate 7 rotates, the torsion spring 11 twists. When the pulley 603 moves away from the clamping plate 7, the torsion spring 11 can drive the clamping plate 7 to reset. At the same time, the torsion spring 11 can prevent the clamping plate 7 on the second supporting plate 5 from sagging under the action of gravity.

[0042] In one embodiment, for the first screw rod 601 , the ends of the first screw rod 601 and the second screw rod 801 are both fixedly connected to a hand wheel 12 .

[0043] In one embodiment, for the above-mentioned workbench 1 , a support leg 13 is fixedly connected to the bottom of the workbench 1 .

[0044] The hand wheel 12 facilitates the staff to rotate the first screw 601 and the second screw 801 , and the legs 13 support the workbench 1 and allow the workbench 1 to have a certain height from the ground, making it convenient for the staff to perform various operations on the workbench 1 .

[0045] Through the above technical solution, 1. through the connection between the adjusting component 6 and the clamping plate 7, when the adjusting components 6 are close to each other, the adjusting component 6 pushes the clamping plate 7 to rotate inward at the same time, so that the clamping plates 7 are close to each other, thereby being able to fix the smaller cold shrink tube; when the adjusting components 6 are away from each other, the clamping plate 7 on the adjusting component 6 rotates downward, so that the clamping plates 7 are away from each other, at this time the larger cold shrink tube can be fixed, and it can be adjusted according to the size of the cold shrink tube during use, which is more flexible to use. 2. Through the connection between the pulley 603 and the clamping plate 7, the first screw 601 drives the sliding seat 602 and the pulley 603 to move. When the pulleys 603 approach each other, the pulley 603 can push the clamping plate 7 to rotate around the pin 10. At this time, the clamping plate 7 rotates inward at the same time, and the clamping plate 7 can clamp and fix smaller cold shrink tubes. When the first screw 601 reverses, the first screw 601 drives the pulleys 603 to move away from each other, and the clamping plate 7 reverses along the pulley 603. The clamping plates 7 move away from each other, and larger cold shrink tubes can be fixed. It can be adjusted according to actual conditions during use, and is more flexible to use.
