Description

Technical Field

[0001] The present invention relates to the technical field of cable fixing, and in particular to a cable fixing device for an electrical control cabinet and a use method thereof. Background Art

[0002] The cables in the electrical control cabinet need to be fixed, mainly to ensure the safe and reliable operation of the electrical system and to facilitate maintenance. Firstly, the proper fixing method can effectively prevent the cables from being displaced or even damaged due to external factors such as mechanical vibration or impact, thereby reducing the risk of short circuit or other faults caused by cable wear; secondly, good wiring and fixing can also help improve the space utilization inside the electrical control cabinet, making the overall layout more neat and orderly, which is not only conducive to heat dissipation, but also convenient for subsequent inspection and maintenance.

[0003] Traditional electrical control cabinet cables are usually fixed with tools such as cable ties or cable ducts. Although cable ducts can provide a relatively neat and beautiful wiring effect, they usually need to be pre-installed on the inner wall of the cabinet, which makes it inconvenient to use for cables that are far away from the inner wall of the cabinet. Secondly, when new lines are added or existing wiring needs to be adjusted, if the original cable duct setting is not flexible enough, it needs to be removed. The whole process is not only time-consuming but also laborious and increases maintenance costs;

[0004] Although cable ties provide a relatively quick and easy temporary fixing solution, once the bundling is completed, if you want to move or add new cables again, you must cut the original cable ties, which not only wastes materials but also generates extra garbage, which is not conducive to environmental protection. At the same time, because cable ties are essentially a soft material, they are not convenient to form effective support for longer cables, thus affecting the stability of cable position fixation. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-10 As shown, the present invention is a cable fixing device for an electrical control cabinet, comprising a mounting rail 2 arranged in a cabinet body 1, on which a fixing mechanism 3 for fixing cables in the cabinet body 1 in multiple directions is installed; the fixing mechanism 3 comprises a sliding member 31, a movable member 32, a locking member 33 and a linkage locking mechanism 34, a plurality of sliding members 31 are slidably connected to the mounting rail 2, the movable member 32 is deflectively connected to the sliding member 31, and one end of the movable member 32 away from the sliding member 31 is connected to the locking member 33, the linkage locking mechanism 34 is used to lock the sliding position of the sliding member 31, and the linkage locking mechanism 34 is also used to lock the deflection angle and telescopic length of the movable member 32.

[0039] It should be noted that when in use, the mounting rail 2 is fixedly installed at a suitable position on the inner wall of the cabinet 1, and a corresponding number of fixing mechanisms 3 are selected according to the needs of cable fixing, and are installed on the mounting rail 2. The interlocking locking mechanism is unlocked before installation, and then the sliding member 31 is slidably installed on the mounting rail 2, and its position can be adjusted by sliding as needed. At the same time, after the interlocking locking mechanism is unlocked, not only can the movable member 32 be deflected so that an angle deflection occurs between it and the sliding member 31, but the telescopic length of the movable member 32 can also be adjusted as needed, so that the locking member 33 can be flexibly adjusted in multiple directions in the cabinet 1, and the cables in the cabinet 1 can be flexibly fixed by using the locking member 33.

[0040] like Figure 3-5 As shown, the sliding member 31 includes a slider 311, a shell 312 and a protruding plate 313. The slider 311 is slidably connected to the mounting rail 2. The shell 312 is opened at both ends, and the shell 312 is connected to the side of the slider 311 close to the movable member 32. The two protruding plates 313 are symmetrically installed on the edge of the opening at one end of the shell 312.

[0041] It should be noted that the slider 311 in this embodiment is a U-shaped structure, but is not limited to the U-shaped structure. The inner walls on both sides of the slider 311 are provided with limiting grooves, and the limiting strips corresponding to the limiting grooves are symmetrically installed on both sides of the mounting rail 2 (such as Figure 1 As shown), the slider 311 can slide along the length direction of the mounting rail 2 by using the limiting strip and the limiting groove, and will not be separated from the mounting rail 2 during the sliding process, thereby improving the sliding stability.

[0042] like Figure 3-4 and Figure 6 As shown, the movable part 32 includes an outer shell 322 with a U-shaped opening 321, a pin 323 and an inner sliding column 324. The U-shaped opening 321 is set at one end of the outer shell 322 close to the sliding part 31, the pin 323 is set through the U-shaped opening 321, and the pin 323 is rotatably connected to the convex plate 313, and the inner sliding column 324 is slidably plugged into the outer shell 322.

[0043] It should be noted that the U-shaped opening 321 extends between the two convex plates 313. When the outer shell 322 is deflected, the angle will be adjusted along the axis of the pin shaft 323, and when the outer shell 322 is deflected, the pin shaft 323 will be driven to rotate. In order to improve the stability of rotation, the pin shaft 323 and the convex plate 313 are rotatably connected through a bearing.

[0044] like Figure 3-4 and Figure 7 As shown, the locking member 33 includes a collar 331, an arc-shaped pressure block 332, a gasket 333 and a threaded member 334. The collar 331 is connected to the end of the inner sliding column 324. A plurality of arc-shaped pressure blocks 332 are distributed circumferentially along the inner wall of the collar 331. The threaded member 334 penetrates the side wall of the collar 331 and is rotatably connected to the arc-shaped pressure block 332 through a bearing. The gasket 333 is installed on the side of the arc-shaped pressure block 332 away from the threaded member 334.

[0045] It should be noted that the plurality of arc-shaped pressure blocks 332 are evenly distributed in the circumferential direction. In the present embodiment, the number of the arc-shaped pressure blocks 332 is four, but not limited to four. To facilitate adjustment of the angle of the collar 331, the collar 331 is rotatably connected to the end of the inner slide column 324 via a rotating damping shaft. A threaded hole for the threaded member 334 to be screwed in is provided on the side wall of the collar 331. After a plurality of cables to be fixed pass through the collar 331, the threaded member 334 is tightened to drive the arc-shaped pressure block 332 close to the cable. The gasket 333 can not only improve the stability of the cable compression and positioning, but also facilitate the protection of the cable.

[0046] like Figure 2 and 4 -6, the linkage locking mechanism 34 includes a sliding positioning assembly, a deflection positioning assembly and a telescopic positioning assembly. The sliding positioning assembly is arranged between the slider 311 and the mounting rail 2, the deflection positioning assembly is arranged between the convex plate 313 and the U-shaped opening 321, and the telescopic positioning assembly is arranged between the inner slide column 324 and the U-shaped opening 321.

[0047] It should be noted that the sliding positioning assembly is used to conveniently lock the position of the slider 311 sliding along the mounting rail 2, and the deflection positioning assembly is used to conveniently synchronously lock the deflection angle and telescopic length of the movable part 32 when the slider 311 is locked.

[0048] like Figure 1 and Figure 8-9 As shown, the sliding positioning assembly includes a T-shaped plug block 341, a first tooth block 342, a spur rack 343 and a first spring 344. The T-shaped plug block 341 is slidably plugged into the slider 311. The spur rack 343 is embedded and installed on the side of the mounting rail 2 away from the inner wall of the cabinet 1. The first tooth block 342 is installed on one end of the T-shaped plug block 341 close to the spur rack 343. Two first springs 344 are symmetrically connected between the slider 311 and the T-shaped plug block 341.

[0049] It should be noted that a socket for the T-shaped plug block 341 to be plugged into is provided on the side wall of the slider 311. When the first spring 344 is in a normal unstretched state, the first tooth block 342 installed at the end of the T-shaped plug block 341 will extend out of the socket. Therefore, before installing the slider 311, it is necessary to push the T-shaped plug block 341 to stretch the first spring 344 so that the first tooth block 342 enters the socket, and then the slider 311 is slidably installed on the mounting rail 2. When the first spring 344 drives the T-shaped plug block 341 to reset, the first tooth block 342 can engage with the spur rack 343, thereby locking the position of the slider 311.

[0050] like Figure 8-9As shown, a pressing mechanism 4 for driving the T-shaped plug 341 to slide is installed on the shell 312, and the pressing mechanism 4 includes a pressing block 41, an extrusion slot 42, a pressing rod 43 and a third spring 44. The extrusion slot 42 is opened through the T-shaped plug 341, and the end of the extrusion slot 42 away from the slider 311 is inclined. The pressing block 41 is slidably plugged into the extrusion slot 42, and one side of the pressing block 41 is fitted with the inclined end of the extrusion slot 42. The pressing rod 43 slides through the top of the shell 312 and is connected to the pressing block 41. The third spring 44 is installed in the shell 312, and the top of the third spring 44 is connected to the pressing block 41.

[0051] It should be noted that the pressing rod 43 is pressed down to drive the pressing block 41 to descend and compress the third spring 44. When the pressing block 41 moves downward, since the pressing block 41 will apply force to the inclined end of the extrusion slot 42, the T-shaped plug 341 will be pushed to slide along the slider 311 under the action of pressure and stretch the first spring 344. When the pressing rod 43 is released, the third spring 44 drives the pressing block 41 to rise and reset. Under the reset action of the first spring 344, the T-shaped plug 341 will also be driven to slide and reset, thereby facilitating the control of the sliding of the T-shaped plug 341.

[0052] like Figure 6 and Figure 8-9 As shown, the deflection positioning assembly includes a gear 345, an arcuate tooth block 346 and a connecting rod 347. The gear 345 is fixedly sleeved on the pin shaft 323, the arcuate tooth block 346 is located in the U-shaped opening 321, and the arcuate tooth block 346 is connected to the T-shaped plug block 341 through a symmetrically arranged connecting rod 347.

[0053] It should be noted that when the pressing mechanism 4 drives the T-shaped plug 341 to slide, the T-shaped plug 341 will drive the arc-shaped tooth block 346 to separate from the gear 345 on the pin shaft 323 through the connecting rod 347. At this time, the rotational freedom of the pin shaft 323 is no longer restricted, so it is convenient to adjust the deflection angle of the outer shell 322 as needed. Similarly, when the T-shaped plug 341 is reset, it will drive the arc-shaped tooth block 346 to re-engage with the gear 345 to achieve angle locking.

[0054] like Figure 6 , Figure 8 and Fig.10As shown, the telescopic positioning assembly includes an arcuate bar 349 with a ball 348, an arcuate push plate 3410, a lifting block 3411, a second spring 3412, a second tooth block 3413 and an L-shaped rack 3414. The arcuate push plate 3410 is connected to one end of the connecting rod 347 away from the T-shaped plug block 341. The arcuate bar 349 is located above the edge of the arcuate push plate 3410. A plurality of balls 348 are installed at the bottom of the arcuate bar 349. The arcuate bar 349 is connected to the L-shaped rack 3414 through the lifting block 3411. The lifting block 3411 is connected to the top of the U-shaped opening 321 through the second spring 3412. The L-shaped rack 3414 is slidably plugged into the top of the U-shaped opening 321. The second tooth block 3413 is located below the L-shaped rack 3414, and the second tooth block 3413 is connected to the side wall of the inner sliding column 324 near the end.

[0055] When the outer sleeve 322 is in a state of being pressed down, the L-shaped rack 3414 is lifted up and the second spring 3412 is compressed. When the inner sleeve 322 is in a state of being pressed down, the L-shaped rack 3414 is lifted up and the second spring 3412 is compressed. When the inner sleeve 322 is in a state of being pressed down, the L-shaped rack 3414 is lifted up and the second spring 3412 is compressed. When the inner sleeve 322 is in a state of being pressed down, the L-shaped rack 3414 is lifted up and the second gear block 3413 is compressed. When the inner sleeve 324 ...

[0056] A method for using a cable fixing device for an electrical control cabinet comprises the following steps:

[0057] S1: Fix the mounting rail 2 on the inner wall of the cabinet 1;

[0058] S2: Press the pressing mechanism 4 downward to slide the T-shaped insert block 341, thereby driving the first tooth block 342 to slide into the side wall of the slider 311, and then install the slider 311 on the mounting rail 2 and slide to adjust its position;

[0059] S3: During the sliding process of the T-shaped plug 341, the arc-shaped tooth block 346 is driven to separate from the gear 345, so that the angle of the movable part 32 can be deflected and adjusted. At the same time, during the sliding process of the T-shaped plug 341, the arc-shaped push plate 3410 will lift the arc-shaped bar 349 equipped with the ball 348, thereby driving the L-shaped rack 3414 to separate from the second tooth block 3413, so that the length of the movable part 32 can be telescopically adjusted;

[0060] S4: Release the pressing mechanism 4 to reset the T-shaped plug 341, thereby locking the position of the slider 311, the deflection angle of the movable part 32, and the telescopic length of the movable part 32. Then, pass the multiple cables to be fixed through the ring 331, rotate the threaded part 334 to drive the arc-shaped pressing block 332 to press the cables, and the cables can be fixed.

[0061] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
