Description
Technical Field
[0001] The utility model belongs to the technical field of the production of signal lines, and relates to a limiting wheel unit for a wire guiding cylinder. Background Art
[0002] A signal line mainly refers to a line used to transmit sensing information and control information in an electrical control circuit. Signal lines often consist of multiple cable lines bundled together or multiple bundles of transmission lines, or can also be printed lines arranged in a printed circuit board. With the continuous progress of technology and applications, signal lines have developed from metal carriers to other carriers, such as optical cables.
[0003] Among them, the signal line mainly includes an outer protective layer and an inner core wire. During the production process of some signal lines, it is also necessary to wind aluminum foil on the outer wall of the core wire to achieve the effect of signal shielding through the aluminum foil. The common structure for winding aluminum foil mainly includes a guiding cylinder and an aluminum foil winding disc located below the guiding cylinder; since the core wire is very long, when winding aluminum foil on the core wire, first, many discs of aluminum foil (with a very small width and a very long length) need to be sleeved on the outer wall of the guiding cylinder, and then the core wire is passed through the middle of the winding disc and the guiding cylinder from bottom to top; then the core wire is pulled upward, and at the same time, the aluminum foil disc rotates, and the aluminum foil is wound on the core wire; when a roll of aluminum foil is used up, only the bottommost aluminum foil on the outer wall of the guiding cylinder needs to be vertically moved to the aluminum foil disc, and then the aluminum foil winding continues. There are also two limiting wheels at the bottom of the guiding cylinder, one with an annular groove on its outer wall and the other with a smooth outer wall. Before the core wire enters the guiding cylinder, it will first pass between the two limiting wheels, and the two limiting wheels play a role in limiting and guiding the core wire.
[0004] In order for the core wire to move upward smoothly and also to adapt to different numbers of core wires (some core wires are single, and some are multiple strands), the frame of the limiting wheel (i.e., the limiting wheel is connected to the bottom of the guiding cylinder through the frame) has a certain elasticity, and under the elastic force of the frame, the two limiting wheels are in a state of being tightly pressed against each other, so that single or multiple strands of core wires can be used normally. In order to limit a single core wire, the contact force between the two limiting wheels is relatively large (to prevent the single core wire wound with aluminum foil from slipping out between the two limiting wheels), which results in that when winding aluminum foil on multiple strands of core wires, not only is it difficult to pass the core wire between the two limiting wheels, but also the pressure generated by the limiting wheels on the core wire is relatively large later, and even it is easy to cause relative movement between the aluminum foil wound on the core wire and the core wire (which is likely to lead to a poor shielding effect), and the use effect is poor. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a limiting wheel unit for a wire guiding cylinder, aiming to solve the problem of poor use effect.
[0006] To solve the above technical problems, the present utility model provides a limit wheel unit for a wire guide cylinder, which includes a first elastic frame and a second elastic frame. The tops of the first elastic frame and the second elastic frame are connected to the bottom of a guide cylinder. A first connection block is arranged at the bottom of the first elastic frame, and a second connection block is arranged at the bottom of the second elastic frame. A first limit wheel is rotatably arranged on the side of the first connection block, and a second limit wheel opposite to the first limit wheel is arranged on the side of the second connection block. An annular limit groove is formed on the outer wall of the first limit wheel. A first receiving groove is formed on the top of the first connection block on one side relative to the second connection block, and a second receiving groove is formed on the top of the second connection block. An adjusting rod is threadedly connected to the side of the first receiving groove. An adjusting disc is arranged on the outer wall of the adjusting rod. An anti-detachment part with a U-shaped longitudinal section is arranged in the second receiving groove. A through opening is formed between the anti-detachment part and the second connection block. The free end of the adjusting rod movably passes through the through opening. An elastic member in a continuously compressed state is arranged between the adjusting disc and the anti-detachment part.
[0007] The present utility model is further arranged such that the elastic member is movably wound around the outer wall of the adjusting rod.
[0008] The present utility model is further arranged such that the longitudinal section of the through opening is in the shape of a vertical long strip.
[0009] The present utility model is further arranged to further include a plurality of limit plates. A plurality of the limit plates are arranged between the adjusting disc and the inner wall of the first receiving groove. The limit plates are in a fitting state with the inner wall of the first receiving groove, the limit plates and the adjusting disc, and adjacent limit plates.
[0010] The present utility model is further arranged such that a hole for the adjusting rod to movably pass through is formed in the middle of the limit plate.
[0011] The present utility model is further arranged such that a rotating part for rotating the adjusting rod is arranged at the free end of the adjusting rod, and the longitudinal section of the rotating part is in the shape of a hexagonal prism or a square.
[0012] The present utility model is further arranged such that a card entry for the adjusting rod to be inserted into the through opening is formed on the anti-detachment part.
[0013] The present utility model is further arranged such that the card entry is inclined, and the adjusting rod is in a misaligned or crossed state with the card entry.
[0014] Compared with the prior art, the utility model provides a limiting wheel assembly for a wire guide cylinder. During use, the first elastic frame and the second elastic frame drive the first connecting block and the second connecting block toward each other, and make the side portions of the first limiting wheel and the second limiting wheel in a state of interference, and in the process of limiting the core wire, the core wire is engaged in the limiting groove. If there is one or a few core wires, the adjusting rod is rotated at this time, and the adjusting disk is attached to the inner wall of the first receiving groove. At this time, the length of the elastic member is the largest, so its elastic force is the smallest, so the pushing force on the first connecting block and the second connecting block is also the smallest, which can be applied to a small number of core wires; if there are more core wires, the adjusting rod is rotated at this time, and a certain distance is maintained between the adjusting disk and the inner wall of the first receiving groove, and the elastic member is further compressed at the same time; under the thrust of the elastic member, the resistance between the first limiting wheel and the second limiting wheel is reduced, or even separated from each other, so that it is convenient to pass the core wire through the first limiting wheel and the second limiting wheel, and the first limiting wheel and the second limiting wheel have a smaller extrusion force on the core wire wrapped with aluminum foil, which can better maintain the wrapping effect of the aluminum foil and ensure the shielding effect. The adjusting rod always maintains a state perpendicular to the inner wall of the first receiving groove, and because the opening of the through-port is large, the angle of the adjusting rod can change, but no matter how the angle of the adjusting rod changes, both ends of the elastic member are against the adjusting disk and the anti-slip portion.

DETAILED DESCRIPTION
[0020] The following further describes in detail the limit wheel unit for a wire guide tube proposed by the present utility model in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model. The same or similar reference numerals in the drawings represent the same or similar components.
[0021] A limit wheel unit for a wire guide tube, as Figures 1 to 4 shown, includes a first elastic frame 1 and a second elastic frame 2. The tops of the first elastic frame 1 and the second elastic frame 2 are connected to the bottom of a guide tube (not within the scope of protection required by this application, introduced here only for auxiliary explanation). A first connection block 3 is provided at the bottom of the first elastic frame 1, and a second connection block 4 is provided at the bottom of the second elastic frame 2. A first limit wheel 5 is rotatably provided on the side of the first connection block 3, and a second limit wheel 6 opposite to the first limit wheel 5 is provided on the side of the second connection block 4. An annular limit groove 7 is formed on the outer wall of the first limit wheel 5. A first receiving groove 8 is formed on one side of the top of the first connection block 3 relative to the second connection block 4, and a second receiving groove 9 is formed on the top of the second connection block 4. An adjusting rod 10 is threadedly connected to the side of the first receiving groove 8. An adjusting disc 11 is provided on the outer wall of the adjusting rod 10. An anti-detachment part 12 with a U-shaped longitudinal section is provided in the second receiving groove 9. A through hole 13 is formed between the anti-detachment part 12 and the second connection block 4. The free end of the adjusting rod 10 movably passes through the through hole 13, and an elastic member 14 continuously in a compressed state is provided between the adjusting disc 11 and the anti-detachment part 12.
[0022] The elastic member 14 is movably wound around the outer wall of the adjusting rod 10. The longitudinal section of the through hole 13 is in a vertically long strip shape.
[0023] It further includes a plurality of limiting plates 15. A plurality of the limiting plates 15 are provided between the adjusting disc 11 and the inner wall of the first receiving groove 8. The limiting plates 15 are in a fitting state with the inner wall of the first receiving groove 8, between the limiting plates 15 and the adjusting disc 11, and between adjacent limiting plates 15. A hole for the adjusting rod 10 to movably pass through is formed in the middle of the limiting plate 15.
[0024] A rotating part 16 for rotating the adjusting rod 10 is provided at the free end of the adjusting rod 10. The longitudinal section of the rotating part 16 is in a hexagonal prism shape or a square shape.
[0025] A card entrance 17 is formed in the anti - detachment part 12 for the adjusting rod 10 to be inserted into the through - opening 13. The card entrance 17 is inclined, and the adjusting rod 10 is in a misaligned or crossed state with the card entrance 17.
[0026] In the limit wheel unit for the wire guide cylinder provided by the present utility model, during use, the first elastic frame 1 and the second elastic frame 2 drive the first connecting block 3 and the second connecting block 4 towards each other, and the sides of the first limit wheel 5 and the second limit wheel 6 are in a state of abutment. During the process of limiting the core wire, the core wire is engaged in the limit groove 7. If there is one or a small number of core wires, at this time, rotate the adjusting rod 10 so that the adjusting disc 11 fits against the inner wall of the first receiving groove 8. At this time, the length of the elastic member 14 is the largest, so its elastic force is the smallest. Thus, the pushing force on the first connecting block 3 and the second connecting block 4 is the smallest, which can be applicable to a small number of core wires. If the number of core wire strands is large, at this time, rotate the adjusting rod 10 so that there is a certain distance between the adjusting disc 11 and the inner wall of the first receiving groove 8, and at the same time, the elastic member 14 is further compressed. Under the thrust of the elastic member 14, the abutting force between the first limit wheel 5 and the second limit wheel 6 is reduced or even they are separated from each other. Thus, it is convenient to pass the core wire through between the first limit wheel 5 and the second limit wheel 6. At the same time, the squeezing force of the first limit wheel 5 and the second limit wheel 6 on the core wire wrapped with aluminum foil is also small, which can better maintain the wrapping effect of the aluminum foil and ensure the shielding effect. Among them, the adjusting rod 10 always remains perpendicular to the inner wall of the first receiving groove 8. At the same time, due to the large opening of the through - opening 13, the angle of the adjusting rod 10 can change. However, no matter how the angle of the adjusting rod 10 changes, both ends of the elastic member 14 are abutted against the adjusting disc 11 and the anti - detachment part 12.
[0027] Before connecting the adjusting rod 10 to the first connecting block 3, first manually pass the rotating part 16 through the elastic member 14 (preferably a spring), and make one end of the elastic member 14 abut against the adjusting disc 11. Then manually or use tools (such as tweezers or pliers) to compress the elastic member 14, and rotate the angle of the adjusting rod 10 so that after the adjusting rod 10 is in an inclined state, it passes through the card entrance 17 and enters the through - opening 13. Then rotate the adjusting rod 10 to a horizontal state, and thread - connect the free end of the adjusting rod 10 to the threaded hole on the inner wall of the first receiving groove 8. After loosening the elastic member 14, the elastic member 14 can apply a force to push the first connecting block 3 and the second connecting block 4 away from each other. Among them, the above operations are all manually performed by workers.
[0028] Since the longitudinal section passing through the through-hole 13 is strip-shaped, even if the angle of the adjusting rod 10 changes, both sides of the adjusting rod 10 can be limited by the anti-disengagement portion 12 and the inner wall of the second receiving groove 9 at this time. At the same time, since the engaging port 17 is inclined, the inner wall of the anti-disengagement portion 12 can always limit the adjusting rod 10, and at the same time, it can also reduce the stress between the adjusting rod 10 and the first connecting block 3, so that the adjusting rod 10 can be used normally.
[0029] During the use process, a plurality of limiting plates 15 can also be sleeved on the adjusting rod 10. At this time, the adjusting disc 11, the inner wall of the first limiting groove 7 and the limiting plates 15 are in a fitting state. In this way, the position of the adjusting disc 11 can be ensured, that is, even if the core wire is very long and the processing time is very long, the clamping force on the core wire can be fully ensured. Moreover, in the actual use process, the number of the limiting plates 15 can be selected according to the actual situation, so that the adjusting effect is better and the adjusting range is wider.
[0030] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the field of the present invention according to the above disclosure are within the protection scope of the claims.
