Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a cable through-hole locking protection device. Background Art

[0002] The realization of the functions of modern mechanical equipment is inseparable from the layout of various lines. Whether in people's daily lives or in the work process of related fields such as mechanical engineering, we often see various lines, which play different functions. Common lines include optical fibers, electric wires, network cables, etc., which are generally used for signal and energy transmission.

[0003] Scenarios where cables are needed for signal or energy transmission generally have a certain distance. Whether it is wiring and installation between several devices, or around a device, for signal and energy transmission between various parts of the device, cables need to be laid. When laying cables, in order to choose a shorter transmission distance and a safer laying location, the cable laying route often has a complex laying environment and passes through complex equipment structures, such as the need for cable vias.

[0004] At present, under normal circumstances, cables are usually fixed with common universal parts such as glands after passing through holes. If the diameters of both ends of the cable are equal and the hole is in a static and safe position, it can be fixed with parts of suitable size; but if the cable ends have connectors or assemblies that are inconsistent with the cable diameter, and a hole is required at the same time, then there will be an embarrassing situation of "the head can fit but the body cannot fit": the cable can pass through the hole, but the connected assembly cannot pass through the fixing parts; or the cable and its assembly can pass through the hole, but the cable cannot be locked and fixed. Furthermore, when the via is opened in the moving part of the equipment, universal parts are often unable to resist the acceleration generated by the moving parts, which can easily cause the cable through the hole to slip off, or move irregularly in the via and entangle with each other, or directly slip out of the hole and disconnect from other parts. How to solve the above defects, propose a cable through hole locking protection device, ensure that various cables are stably locked and not shaken when laid out in the through hole, and can run synchronously with the moving part without interference when laid out in the moving part. Research is urgent. Utility Model Content

[0025] See also Figure 1-Figure 2 The present embodiment provides a cable through-hole locking protection device, including a device body 1, the device body 1 is sleeved on the outside of the cable 2, and an assembly 21 is arranged at one end of the cable 2. The device body 1 includes a bottom plate 11, a limit plate 12, a pressure block 13, a cover plate 14 and a locking bolt 15. The bottom plate 11 is provided with a first through hole 111, and the cover plate 14 is provided with a second through hole 141. The first through hole 111 and the second through hole 141 are for the cable 2 to pass through. The limit plates 12 are provided with a pair, symmetrically arranged between the bottom plate 11 and the cover plate 14, and the two limit plates 12 have limit grooves 121 on opposite sides. The pressure blocks 13 are provided with a pair, which are respectively installed in the limit grooves 121 of the two limit plates 12. The pair of pressure blocks 13 is used to clamp and fix the cable 2. The cover plate 14, the limit plate 12 and the bottom plate 11 are locked and fixed by the locking bolts 15.

[0026] As a preferred embodiment, the bottom plate 11 is fixed to the cable through hole of the cable laying equipment, and the fixing method can be welding, screw fixing, etc., and a suitable fixing method is adopted according to the design requirements, and then a pair of limit plates 12 are installed on the top of the bottom plate 11 in sequence, and a pair of pressing blocks 13 are installed in the limit grooves 121 of the pair of limit plates 12, and then the cover plate 14 is installed on the top of the pair of limit plates 12, and then the cover plate 14, the limit plate 12 and the bottom plate 11 are locked and fixed by the locking bolts 15 to fix the position of the pressing block 13, and the pair of pressing blocks 13 are installed in the top of the limit plates 12. The block 13 can clamp and fix the cable 2, and can allow different types of cables 2 and their assemblies 21 to pass through the cable holes smoothly, and then lock and fix the cable 2 in the position to be fixed. The device can resist external pressure, impact and vibration interference through the combination of the bottom plate 11, the limit plate 12, the pressure block 13, and the cover plate 14, and protect the internal cable 2 to avoid relative movement with the hole, causing bending, breakage and other damage; the entire device itself is fixed and pressed, and welded on the cable laying equipment, and can move synchronously with the equipment, and is stable and will not fall off.

[0027] In this embodiment, if Figure 1 and Figure 2 As shown, the base plate 11, the limit plate 12 and the cover plate 14 are all provided with coaxially arranged reserved bolt holes, and the locking bolts 15 are connected and assembled in the reserved bolt holes. There are multiple reserved bolt holes, and four are preferably provided in this embodiment. The locking bolts 15 are used to connect and fix the base plate 11, the limit plate 12 and the cover plate 14 together and then lock and fix them. The structure is simple and the operation is convenient.

[0028] In this embodiment, if Figure 1 and Figure 2 As shown, the pressing block 13 and the limiting plate 12 have the same thickness, which prevents the pressing block 13 from protruding from the surface of the limiting plate 12 and affecting the locking and assembly effect. It can also maximize the contact area between the pressing block 13 and the cable 2 and improve the clamping effect on the cable 2.

[0029] In this embodiment, the pressure block 13 is made of elastic material, and the pressure block 13 is preferably made of silicone rubber. A pair of pressure blocks 13 are used to clamp the cable 2 to complete the clamping and fixing function. After the cable 2 is compressed, the material rebounds to form two half holes on the side, so as to take into account the clamping function while reducing damage to the cable 2.

[0030] In this embodiment, if Figure 2As shown, the function of the limiting plate 12 is to limit the pressure block 13. The material of the limiting plate 12 can be an epoxy board. In another embodiment, a mortise and tenon structure is provided between a pair of limiting plates 12, wherein one end of one limiting plate 12 is provided with a tenon, and one end of the other limiting plate 12 is provided with a mortise. The pair of limiting plates 12 are positioned and connected by the tenon and the mortise, which is used to ensure the positioning and assembly of the pair of limiting plates 12 when the pair of limiting plates 12 are assembled to avoid position deviation, and can play a role in initially fixing the pressure block 13.

[0031] In this embodiment, if Figure 2 As shown, the bottom plate 11 and the cover plate 14 are both made of hard materials with a certain degree of deformation resistance. The bottom plate 11 and the cover plate 14 are preferably made of one of carbon steel and stainless steel, wherein the thickness of the bottom plate 11 is greater than that of the cover plate 14. The bottom plate 11 is used to withstand the pressure of the entire device and should have a thicker thickness. It should be noted that the cover plate 14 and the bottom plate 11 can be designed with different shapes or structures according to different usage conditions.

[0032] In this embodiment, if Figure 2 As shown, the first through hole 111 and the second through hole 141 are coaxially arranged to accommodate the maximum diameter portion of the through-hole cable 2. Both sides of the first through hole 111 and the second through hole 141 are chamfered to make the edges of the holes smoother and free of burrs, thereby avoiding damage to the cable 2. It should be noted that the first through hole 111 and the second through hole 141 can be designed with different shapes or structures according to different usage scenarios.

[0033] As a preferred implementation of this embodiment, Figure 3 As shown, a plurality of cables can be passed through the first through hole 111 and the second through hole 141 , and a pair of limiting plates 12 can be used to clamp and fix the plurality of cables at the same time.

[0034] Working principle: When in use, first place the base plate 11 at the cable through-hole of the cable laying equipment, and make the first through-hole 111 coincide with the central axis of the cable through-hole. At this position, fix the base plate 11 by a suitable fixing method. After the cable 2 and its assembly 21 pass through the cable through-hole and the first through-hole 111 of the base plate 11, pull them out the required distance. Then, install a pair of pressure blocks 13 inwardly from both sides of the cable 2 to clamp the cable 2. Then, install a pair of limit plates 12 inwardly from both sides of the pressure blocks 13 to ensure that the pressure blocks 13 are fixed in the limit grooves 121. Finally, press the cover plate 14 from top to bottom on one side of the limit plate 12. After the assembly is completed, use the locking bolts 15 to lock and fix through the reserved bolt holes to complete the installation of the entire device body 1.

[0035] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
