Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering technology, and in particular to a cable fixing device for low-voltage engineering cable construction layout. Background Technology

[0002] During the installation of equipment used in low-voltage engineering, many cables are used, requiring cable fasteners for secure fixation. For example, existing patent publication number CN212908825U, entitled "A Cable Fastener for Low-Voltage Engineering Cable Construction Layout," proposes that this utility model includes a fixing base, with a U-shaped plate fixedly installed on the upper surface of the fixing base. Simultaneously, several partition plates are sequentially fixedly installed on the inner side of the U-shaped plate's port. The other side of the partition plates is fixedly connected to the fixing base, and the partition plates divide the U-shaped plate into several installation areas. Several installation slots are sequentially formed on the upper surface of the fixing base. The beneficial effects of this utility model are: by setting several installation areas, an upper clamping seat, a lower clamping seat, a fastening screw, an arc-shaped clamping plate, and a return spring, the cables are inserted into the lower clamping seat. Then, rotating the fastening screw lowers the height of the upper clamping seat, causing the arc-shaped clamping plate to adhere to the cable. At this time, the return spring is in a compressed state, thus facilitating the fixation of cables of different sizes.

[0003] However, the cable fixing device for low-voltage engineering cable construction layout disclosed in the above patent has a fixed number of installation slots during use, and cannot be freely adjusted according to the number of cables, resulting in low applicability. Therefore, it is necessary to propose a cable fixing device for low-voltage engineering cable construction layout to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cable fixing device for low-voltage engineering cable construction layout, so as to solve the problem mentioned in the background art that the number of mounting slots of the existing low-voltage engineering cable fixing device is fixed during use, and the number of mounting slots cannot be freely adjusted according to the number of cables, resulting in low applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable fixing device for the construction layout of low-voltage engineering cables, comprising a lower fixing plate and an upper fixing plate, wherein the lower fixing plate and the upper fixing plate are rotatably connected by a connecting component, an mounting plate is fixedly provided on the side of the lower fixing plate, a lower sliding plate is slidably provided inside the lower fixing plate, and an upper sliding plate is slidably provided inside the upper fixing plate. The lower fixing plate and the upper fixing plate have the same structure, and the lower sliding plate and the upper sliding plate have the same structure.

[0006] A limiting component is provided between the lower fixed plate and the lower sliding plate. The limiting component includes a sliding groove, which is fixedly opened inside the lower fixed plate and passes through the right end of the lower fixed plate. The lower sliding plate is slidably disposed inside the sliding groove. The upper surfaces of the lower fixed plate and the lower sliding plate are on the same plane. The lower fixed plate and the lower sliding plate are respectively fixedly opened with an installation groove and an auxiliary groove. Several installation grooves and auxiliary grooves are equidistantly distributed. The installation grooves and auxiliary grooves correspond one-to-one. The vertical cross-section of the installation grooves and auxiliary grooves is semi-circular.

[0007] Preferably, a first connecting plate is fixedly provided at the right end of the lower sliding plate, and a second connecting plate is fixedly provided at the right end of the upper sliding plate. A bolt is connected between the first connecting plate and the second connecting plate, and a nut is threaded onto the outer ring of the bolt.

[0008] Preferably, the connecting assembly includes a fixed shaft fixedly disposed at the left end of the lower fixed plate, an L-shaped rod fixedly disposed at the left end of the upper fixed plate, a sleeve rotatably disposed at the outer ring of the fixed shaft, and the other end of the L-shaped rod being fixedly connected to the sleeve.

[0009] Preferably, the upper surface of the lower fixing plate and the lower surface of the upper fixing plate are attached to each other.

[0010] Preferably, two symmetrically distributed limiting grooves are fixedly provided on the bottom of the inner side of the lower fixing plate, and a limiting strip is slidably provided inside the limiting groove. The limiting strip is fixedly connected to the lower surface of the lower sliding plate, and the vertical cross-section of the limiting groove and the limiting strip are both "T" shaped.

[0011] Preferably, a plurality of equidistantly arranged positioning grooves are fixedly provided in the middle of the bottom inner side of the lower fixing plate. The positioning grooves are located between two adjacent mounting grooves. A plurality of equidistantly arranged lifting grooves are fixedly provided inside the positioning grooves. The lifting grooves correspond one-to-one with the positioning grooves. A lifting plate is slidably provided inside the lifting groove. A first spring is fixedly connected between the inner wall of the lifting groove and the lifting plate. A positioning ball is fixedly provided on the lower surface of the lifting plate. The positioning ball is movably engaged into the interior of the positioning groove.

[0012] Preferably, the inner walls of both the mounting groove and the auxiliary groove are provided with gaskets, and a second spring is fixedly connected between the gaskets and the inner walls of the auxiliary groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. In the use of this utility model, when the number of cables exceeds the number of mounting slots, the lower sliding plate is pulled to the right a certain distance, causing it to protrude from the left end of the lower fixing plate. The number of auxiliary slots protruding depends on the number of cables. Similarly, the upper sliding plate is pulled out by the same distance. At this time, the auxiliary slots inside the lower fixing plate still correspond to the mounting slots. After placing the cables one by one on the mounting slots and protruding auxiliary slots on the lower fixing plate, the upper fixing plate is rotated so that the upper surface of the lower fixing plate and the lower surface of the upper fixing plate are in contact. After passing the bolts through the first connecting plate and the second connecting plate, the nuts are tightened to complete the fixing of the cables. This solves the problem that the number of mounting slots in the existing cable fixing devices for low-voltage engineering construction layout is fixed and cannot be freely adjusted according to the number of cables, resulting in low applicability.

[0015] 2. By setting up positioning grooves and positioning balls, when the sliding plate slides down, the positioning ball retracts into the interior of the lifting groove, and the first spring is compressed. When the positioning ball moves one unit, it engages with the interior of the next positioning groove, thereby reminding the user that it has moved one unit distance, ensuring that the auxiliary groove and the mounting groove inside the lower fixed plate can still correspond to each other, thus improving the flexibility of the device.

[0016] 3. By using a shim and a second spring, the cable is elastically fixed, ensuring a certain pressure and effectively protecting the cable. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] This utility model provides, for example Figures 1-5 The cable fixing device shown includes a lower fixing plate 1 and an upper fixing plate 2. The lower fixing plate 1 and the upper fixing plate 2 are rotatably connected by a connecting component. An mounting plate 7 is fixedly installed on the side of the lower fixing plate 1. A lower sliding plate 3 is slidably installed inside the lower fixing plate 1. An upper sliding plate 4 is slidably installed inside the upper fixing plate 2. Since the lower fixing plate 1 and the upper fixing plate 2 have the same structure, and the lower sliding plate 3 and the upper sliding plate 4 have the same structure, the structure of the lower fixing plate 1 and the lower sliding plate 3 is used as an example in this utility model.

[0025] A limiting component is provided between the lower fixed plate 1 and the lower sliding plate 3. The limiting component includes a sliding groove, which is fixedly opened inside the lower fixed plate 1 and passes through the right end of the lower fixed plate 1. The lower sliding plate 3 is slidably arranged inside the sliding groove. The upper surfaces of the lower fixed plate 1 and the lower sliding plate 3 are on the same plane. The lower fixed plate 1 and the lower sliding plate 3 are respectively fixedly opened with an installation groove 8 and an auxiliary groove 9. Several installation grooves 8 and auxiliary grooves 9 are arranged at equal intervals. The installation grooves 8 and auxiliary grooves 9 correspond one-to-one. The vertical cross-section of the installation grooves 8 and auxiliary grooves 9 is semi-circular.

[0026] The lower slide plate 3 is fixedly provided with a first connecting plate at its right end, and the upper slide plate 4 is fixedly provided with a second connecting plate at its right end. A bolt 18 is connected between the first connecting plate and the second connecting plate, and a nut 19 is threaded onto the outer ring of the bolt 18.

[0027] The connecting assembly includes a fixed shaft 5 fixedly installed at the left end of the lower fixed plate 1, an L-shaped rod 6 fixedly installed at the left end of the upper fixed plate 2, a sleeve rotatably installed at the outer ring of the fixed shaft 5, and the other end of the L-shaped rod 6 fixedly connected to the sleeve.

[0028] Specifically, in the use of this utility model, when the number of cables exceeds the number of mounting slots 8, the lower sliding plate 3 is pulled to the right and displaced a certain distance, causing the lower sliding plate 3 to protrude from the left end of the lower fixing plate 1. The number of auxiliary slots 9 protruding depends on the number of cables. Similarly, the upper sliding plate 4 is pulled out by the same distance. At this time, the auxiliary slots 9 inside the lower fixing plate 1 still correspond to the mounting slots 8. After placing the cables one by one on the mounting slots 8 and the protruding auxiliary slots 9 on the lower fixing plate 1, the upper fixing plate 2 is rotated so that the upper surface of the lower fixing plate 1 and the lower surface of the upper fixing plate 2 are in contact. After the bolts 18 are passed through the first connecting plate and the second connecting plate, they are tightened with nuts 19 to complete the fixing of the cables. This solves the problem that the number of mounting slots 8 in the existing cable fixing devices for low-voltage engineering construction layout is fixed and cannot be freely adjusted according to the number of cables, resulting in low applicability.

[0029] Furthermore, two symmetrically distributed limiting grooves 10 are fixedly provided on the bottom of the inner side of the lower fixed plate 1. A limiting strip 11 is slidably provided inside the limiting groove 10. The limiting strip 11 is fixedly connected to the lower surface of the lower slide plate 3. The vertical cross-section of the limiting groove 10 and the limiting strip 11 is a "T" shaped structure. The stability of the displacement of the lower slide plate 3 is improved by setting the limiting groove 10 and the limiting strip 11.

[0030] Furthermore, a number of equidistantly arranged positioning grooves 12 are fixedly opened in the middle of the bottom inner side of the lower fixing plate 1. The positioning grooves 12 are located between two adjacent mounting grooves 8. A number of equidistantly arranged lifting grooves are fixedly arranged inside the positioning grooves 12. The lifting grooves and the positioning grooves 12 correspond one to one. A lifting plate 14 is slidably arranged inside the lifting groove. A first spring 15 is fixedly connected between the inner wall of the lifting groove and the lifting plate 14. A positioning ball 13 is fixedly arranged on the lower surface of the lifting plate 14. The positioning ball 13 is movably engaged into the interior of the positioning groove 12.

[0031] With the positioning groove 12 and positioning ball 13 in place, when the sliding plate 3 is slid down, the positioning ball 13 retracts into the lifting groove, and the first spring 15 is compressed. When the positioning ball 13 moves one unit, it engages with the inside of the next positioning groove 12, thereby reminding the user that it has moved one unit distance. This ensures that the auxiliary groove 9 and the mounting groove 8 inside the lower fixed plate 1 can still correspond to each other, thus improving the flexibility of the device.

[0032] Furthermore, both the inner walls of the mounting groove 8 and the auxiliary groove 9 are provided with gaskets 16, and a second spring 17 is fixedly connected between the gaskets 16 and the inner walls of the auxiliary groove 9. Through the setting of the gaskets 16 and the second spring 17, the cable is elastically fixed to ensure a certain pressure and achieve effective protection of the cable.

[0033] Working principle: During use, when the number of cables exceeds the number of mounting slots 8, the lower slide plate 3 is pulled to the right and displaced a certain distance, causing it to protrude from the left end of the lower fixing plate 1. The number of auxiliary slots 9 protruding depends on the number of cables. Similarly, the upper slide plate 4 is pulled out by the same distance. When the lower slide plate 3 slides, the positioning ball 13 retracts into the lifting slot, and the first spring 15 is compressed. After the positioning ball 13 displaces by one unit, it engages with the inside of the next positioning slot 12, thus reminding the user that it has displaced by one unit. This ensures that the auxiliary slots 9 inside the lower fixing plate 1 still correspond to the mounting slots 8. Then, the cables are placed one by one on the mounting slots 8 and the protruding auxiliary slots 9 on the lower fixing plate 1. The upper fixing plate 2 is then rotated so that the upper surface of the lower fixing plate 1 and the lower surface of the upper fixing plate 2 are in contact. After the bolts 18 are passed through the first connecting plate and the second connecting plate, they are tightened with nuts 19 to complete the fixing of the cables.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
