Description

Technical Field

[0001] This utility model relates to the field of plastic chuck technology, and in particular to an impact-resistant plastic chuck. Background Technology

[0002] A plastic chuck is a tool made primarily of plastic used for winding various types of wires. It is usually disc-shaped with a central core to allow the wire to be wound neatly and orderly around it. It is widely used in daily life and industrial and commercial fields, facilitating the storage and transportation of wires.

[0003] With the widespread use of various electrical equipment and electronic devices, the demand for supporting wires such as electric wires, cables and data cables has increased dramatically. During the production process of these wires, they need to be wound and transported in an orderly manner. However, traditional plastic chucks are prone to breakage due to impact, stacking and transportation. Therefore, an impact-resistant plastic chuck is needed.

[0004] Currently, impact-resistant plastic chucks on the market mainly consist of a chuck body, a reel, and side plates. During use, the wire is wound onto the chuck body, while the side plates and chuck body provide protection for the wire. However, in practical use, due to the varying lengths and thicknesses of different wires, this device is difficult to accommodate the storage needs of various wires. To solve this problem, existing technologies often replace the side plates according to the type of wire, thereby changing the internal storage capacity of the device and enabling the winding of wires of different thicknesses and lengths. However, in actual use, the side plates are often quite large, making disassembly and replacement cumbersome and requiring multiple personnel, increasing the operating cost of the device and failing to meet the user's needs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an impact-resistant plastic chuck, which aims to improve the problem that existing impact-resistant plastic chucks are inconvenient for winding wires of different thicknesses and lengths.

A front side plate is provided on the front side of the hollow disc, and a rear side plate is provided on the rear side of the hollow column. A clamping mechanism is provided on the upper middle part of the rear side of the rear side plate. The clamping mechanism is used to conveniently fix the wire.

[0007] As a further description of the above technical solution:

[0008] The clamping mechanism includes a hollow box, which is fixedly connected to the upper-middle rear side of the rear side plate. A transmission rod is rotatably connected to the middle rear side of the hollow box. The front end of the transmission rod passes through the hollow box and is fixedly connected to a worm gear. Transmission columns are rotatably connected to the upper and lower sides of the interior of the hollow box. Worm wheels are fixedly connected to the right side of the outer wall of each of the two transmission columns. The two worm wheels are respectively meshed with the upper and lower sides of the worm gear. Semicircular plates are fixedly connected to the left side of the outer wall of each of the two transmission columns. Connecting rods are fixedly connected to the middle front side of each of the two semicircular plates. A through slot is provided in the upper-middle front side of the rear side plate.

[0009] As a further description of the above technical solution:

[0010] A groove is provided on the left side of the front wall of the front side plate. The front end of the rotating rod passes through the hollow disc, the front side plate and the groove in sequence and is rotatably connected to a rotating column. The left and right ends of the rotating column are fixedly connected to the same steering clip.

[0011] As a further description of the above technical solution:

[0012] A handle is fixedly connected to the top of the steering card, and a protective sleeve is fixedly connected to the outside of the handle.

[0013] As a further description of the above technical solution:

[0014] A knob is fixedly connected to the rear end of the transmission rod, and the same rubber pad is fixedly connected to the adjacent sides of the two grippers.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the rotating rod drives the gear to rotate. Since the gear meshes with the ring rack, the ring rack drives the rotating ring to rotate. The first rotating shaft drives the first fixing card to move. The first fixing card can push the second fixing card to move through the connecting rod. At this time, the rotating shaft will drive the hollow column to move, and the rear side plate will move accordingly. By adjusting the distance between the rear side plate and the front side plate, the loading capacity of the device can be dynamically adjusted, which improves the practicality of the device and can meet the needs of users.

[0023] 2. In this utility model, the transmission rod drives the worm to rotate. Since the two worm wheels mesh with the two sides of the worm, the worm wheels on both sides will drive the two transmission columns to rotate in opposite directions. The two semicircular plates will rotate accordingly. Since the two semicircular plates are in a state of rotation in opposite directions, they will drive the clamps to approach the wire through the connecting rod, which can easily fix the tail of the wire firmly and reduce the workload of the workers.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an impact-resistant plastic chuck, comprising a hollow disk 1, an annular groove 3 formed on the inner side of the hollow disk 1, a rotating ring 4 rotatably connected to the front side of the inner side of the annular groove 3, and an annular rack 5 fixedly connected to the front side of the rotating ring 4. Rotation of the annular rack 5 causes the rotating ring 4 to rotate. A rotating rod 6 is rotatably connected to the left side of the front end of the inner side of the annular groove 3, and a gear 7 is fixedly connected to the rear end of the rotating rod 6. The gear 7 meshes with the annular rack 5, causing the rotating rod 6 to rotate and the gear 7 to rotate. Since the gear 7 meshes with the annular rack 5, the rotation of the gear 7 causes the annular rack 5 to rotate. First rotating shafts 8 are rotatably connected to the upper and lower sides of the rear wall of the rotating ring 4, and first fixing clips 9 are fixedly connected to the rear ends of the two first rotating shafts 8. Rotation of the rotating ring 4 causes the first fixing clips 9 to move via the first rotating shafts 8. Connecting plates 10 are rotatably connected to the inner sides of the two first fixing clips 9. The movement of the first fixing clips 9... The connecting plate 10 is moved. A hollow column 11 is slidably connected to the rear side of the rotating ring 4. The upper and lower sides of the front end of the hollow column 11 are rotatably connected to the second rotating shaft 12. The front ends of the two second rotating shafts 12 are fixedly connected to the second fixing clips 13. The inner sides of the two second fixing clips 13 are rotatably connected to the corresponding connecting plate 10. When the connecting plate 10 moves, it can push the second fixing clips 13 to move. A front side plate 14 is provided on the front side of the hollow plate 1, and a rear side plate 15 is provided on the rear side of the hollow column 11. The movement of the hollow column 11 will drive the rear side plate 15 to move. A clamping mechanism 2 is provided on the upper middle part of the rear side of the rear side plate 15. The clamping mechanism 2 is used to conveniently fix the wire. The inner sides of the front side plate 14 and the rear side plate 15 are rotatably connected to the bearings 23. The opposite sides of the front side plate 14 and the rear side plate 15 are provided with weight-reducing patterns 24. The weight-reducing patterns 24 are used to reduce the weight of the front side plate 14 and the rear side plate 15.

[0034] Reference Figure 1 and Figure 4The clamping mechanism 2 includes a hollow box 201, which is fixedly connected to the upper middle part of the rear side of the rear side plate 15. A transmission rod 202 is rotatably connected to the middle of the rear side of the hollow box 201. The front end of the transmission rod 202 passes through the hollow box 201 and is fixedly connected to a worm gear 203. Rotation of the transmission rod 202 will drive the worm gear 203 to rotate. Transmission columns 204 are rotatably connected to the upper and lower sides of the interior of the hollow box 201. Worm wheels 205 are fixedly connected to the right side of the outer wall of each of the two transmission columns 204. The two worm wheels 205 are respectively meshed with the upper and lower sides of the worm gear 203. When the worm gear 203 rotates, the two worm wheels 205 will drive the transmission columns 204 to rotate in opposite directions. A semicircular plate 206 is fixedly connected to each of the two semicircular plates 206. The rotation of the transmission column 204 will drive the semicircular plate 206 to rotate. A connecting rod 207 is fixedly connected to the middle of the front side of each of the two semicircular plates 206. A through groove 208 is opened in the upper middle of the front side of the rear plate 15. The front ends of the two connecting rods 207 pass through the hollow box 201 and the through groove 208 in sequence and are fixedly connected to the grippers 209. When the semicircular plate 206 rotates, it can drive the grippers 209 to move through the connecting rods 207. A knob 21 is fixedly connected to the rear end of the transmission rod 202. The knob 21 makes it convenient for the operator to rotate the transmission rod 202. The same rubber pad 22 is fixedly connected to the adjacent side of the two grippers 209. The rubber pad 22 makes it difficult for the wire to slip.

[0035] Reference Figure 1 and Figure 6 A groove 16 is provided on the left side of the front wall of the front side plate 14. The front end of the rotating rod 6 passes through the hollow disc 1, the front side plate 14 and the groove 16 in sequence and is rotatably connected to the rotating column 17. The left and right ends of the rotating column 17 are fixedly connected to the same steering clip 18. The top of the steering clip 18 is fixedly connected to a handle 19, which can be rotated into the groove 16 when the load of the device does not need to be adjusted, so that the device will not be accidentally adjusted. A protective sleeve 20 is fixedly connected to the outside of the handle 19, which makes it convenient for the operator to rotate the handle 19.

[0036] Reference Figure 1 and Figure 4 The front side plate 14 is threaded with first bolts 25 at equal intervals on its front side. The rear ends of the multiple first bolts 25 all pass through the front side plate 14 and are threaded to the hollow disc 1. The front side plate 14 can be disassembled by unscrewing the multiple first bolts 25. The rear side plate 15 is fixedly connected with multiple second bolts 26 at equal intervals on its rear side. The front ends of the multiple second bolts 26 all pass through the rear side plate 15 and are threaded to the hollow column 11. The rear side plate 15 can be disassembled by unscrewing the multiple second bolts 26.

[0037] Working principle: When using this device, first turn the handle 19. Turning the handle 19 will drive the rotating rod 6 to rotate, which in turn will drive the gear 7 to rotate. Since the gear 7 and the ring rack 5 mesh with each other, when the gear 7 rotates, the ring rack 5 will drive the rotating ring 4 to rotate. The rotation of the rotating ring 4 will drive the first rotating shaft 8 to move. At this time, the first fixing clip 9 will move accordingly. When the first fixing clip 9 moves, it can drive the second fixing clip 13 to move through the connecting plate 10. At this time, the second fixing clip 13 will drive the hollow column 11 to slide inside the hollow disc 1 through the second rotating shaft 12. When the hollow column 11 moves, it will drive the rear side plate 15 to move. By adjusting the distance between the rear side plate 15 and the front side plate 14, the device can be dynamically adjusted when loading wires of different lengths and sizes, which is convenient for winding.

[0038] Furthermore, when using this device, after winding is complete, the end of the wire is placed between the two grippers 209. At this time, the knob 21 is turned, and the rotation of the knob 21 will drive the worm gear 203 to rotate through the transmission rod 202. Since the two worm wheels 205 are meshed with the two sides of the worm gear 203 respectively, when the worm gear 203 rotates, the worm wheels 205 on both sides will drive the two transmission columns 204 to rotate in opposite directions. When the transmission columns 204 rotate, they will drive the semicircular plate 206 to rotate. Since the two semicircular plates 206 are in a state of opposite rotation, they will drive the grippers 209 to move closer to the wire through the connecting rod 207, which can easily and firmly fix the end of the wire.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
