DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1-Figure 3 As shown, the technical solution adopted by the utility model is as follows: a fireproof cable harness, comprising an upper harness plate 4 and a lower harness plate 3, wherein the upper harness plate 4 is located above the lower harness plate 3.

A handle 5 is fixedly connected to the center of the top surface of the upper harness plate 4, and the handle 5 is used to facilitate the upper harness plate 4.

[0025] The bottom surface of the upper harness plate 4 and the top surface of the lower harness plate 3 are both provided with four semicircular grooves, and the corresponding semicircular grooves cooperate to form a circular harness groove 6. A cable passes through each harness groove 6, and each harness groove 6 is provided with a clamping assembly for clamping the cable.

[0026] Each clamping assembly includes an upper clamping plate 11 and a lower clamping plate 8, and the upper clamping plate 11 is located above the lower clamping plate 8. The upper clamping plate 11 and the lower clamping plate 8 are both arc-shaped and have a plurality of heat dissipation grooves 9 on the surface. The bottom surface of the lower clamping plate 8 is fixedly connected with a plurality of protrusions 7, and the protrusions 7 are fixedly connected to the lower harness plate 3. The top surface of the lower clamping plate 8 and the bottom surface of the upper clamping plate 11 are fixedly connected with a plurality of heat-conducting strips 10. The heat-conducting strips 10 cooperate with the cable to increase the contact area between the outer surface of the cable and the air, so that the cable has good heat dissipation, and the dissipated heat is released from the heat dissipation grooves 9. The upper clamping plates 11 all move up and down in the harness groove 6, and the top surface of the upper clamping plates 11 is fixedly connected with two connecting shafts 12, and the upper ends of the two connecting shafts 12 both pass through the upper harness plate 4 upward. Four connecting rods 14 are provided on the top surface of the upper harness plate 4, each connecting rod 14 is located above the corresponding harness groove 6, and each connecting rod 14 is fixedly connected to the upper end of the corresponding connecting shaft 12. The outer circumferential surface of each connecting shaft 12 is sleeved with a first spring 13, and the lower end of each first spring 13 is fixedly connected to the top surface of the corresponding upper clamping plate 11, and the upper end is fixedly connected to the upper harness plate 4.

[0027] The upper harness plate 4 is fixedly connected with a card plate 15 on both sides, and the lower harness plate 3 is provided with a limit assembly for limiting the card plate 15. Each limit assembly includes a fixed block 16 and a card block 22. The fixed block 16 is fixedly connected to the lower harness plate 3. The top surface of the fixed block 16 is provided with a card slot, and the card slot is slidably matched with the card plate 15. Slide grooves are provided on both sides of the card slot, and a card block 22 is slidably connected in each slide groove. The top surface of each card block 22 close to one end of the card slot is provided with an inclined surface, and slots that match the card block 22 are provided on both sides of the card plate 15. A third spring 23 is provided in each slide groove, and one end of the third spring 23 is fixedly connected to the card block 22, and the other end is fixedly connected to the inner wall of the slide groove. The outer side of the fixed block 16 is fixedly connected with a fixed shaft 17, and the fixed shaft 17 is sleeved with a second spring 18 and a slider 19, and the slider 19 is slidably connected to the fixed shaft 17. The second spring 18 is located between the slider 19 and the fixed block 16, and its two ends are respectively fixedly connected to the slider 19 and the fixed block 16. Push rods 20 are hinged on both sides of the slider 19, and the other end of each push rod 20 is hinged to a connecting block 21. Two through grooves are provided on the outer side of the fixed block 16, and each through groove is connected to a corresponding slide groove. One end of the two connecting blocks 21 is slidably connected in the corresponding through groove and fixedly connected to the clamping block 22.

[0028] Working principle: In summary, in the initial state, the lower harness plate 3 is not matched with the upper harness plate 4, and the end of the clamping block 22 with the inclined surface is located in the clamping groove.

[0029] When only the device is used, the personnel first place the base plate 1 in the designated working area, and fix the base plate 1 in the designated position by the cooperation of the bolts and the bolt holes 2 .

[0030] Then the personnel places the cable into the semicircular cable trough 6 of the lower cable tying plate 3 so that the cable cooperates with several heat-conducting strips 10 on the lower clamping plate 8. The personnel picks up the upper cable tying plate 4 by the handle 5 so that the upper cable tying plate 4 cooperates with the lower cable tying plate 3, so that the cable is located in the circular cable trough 6.

[0031] During the coordination between the upper harness plate 4 and the lower harness plate 3, the card plate 15 cooperates with the card slot on the fixed block 16, and the card plate 15 slides downward in the card slot. When the bottom surface of the card plate 15 cooperates with the inclined surfaces of the two card blocks 22, the card plate 15 pushes the two card blocks 22 away from each other, and the card blocks 22 push the corresponding third spring 23 to be compressed. At the same time, the two connecting blocks 21 are driven away from each other. The two connecting blocks 21 drive the slider 19 to slide on the fixed shaft 17 toward the fixed block 16 through the hinged push rod 20, and the slider 19 compresses the second spring 18.

[0032] When the bottom surface of the card plate 15 contacts the inner wall of the card slot, the slots on both sides of the card plate 15 and the two card blocks 22 are at the same height, and the two third springs 23 release the stored elastic potential energy to push the two card blocks 22 to slide into the corresponding slots, thereby fixing the upper harness plate 4 and the lower harness plate 3 together. When the card blocks 22 move, the two connecting blocks 21 are driven to approach each other, so that the slider 19 slides on the fixed shaft 17 through the two push rods 20, and the second spring 18 is extended.

[0033] In the process of the upper harness plate 4 and the lower harness plate 3 cooperating, several heat-conducting strips 10 on the upper clamp plate 11 cooperate with the cable. When the diameter of the cable is equal to the distance between the upper clamp plate 11 and the lower clamp plate 8, the upper clamp plate 11 does not move. When the diameter of the cable is greater than the distance between the upper clamp plate 11 and the lower clamp plate 8, the cable pushes the upper clamp plate 11 to move upward in the harness groove 6, and the upper clamp plate 11 compresses the two first springs 13 above, and at the same time drives the two connecting shafts 12 to move upward, and the connecting shafts 12 drive the corresponding connecting rods 14 to move upward. By moving the upper clamp plate 11 up and down, cables of different diameters can be clamped, and the scope of use is wider.

[0034] When it is necessary to remove the cable, push the sliders 19 on both sides of the lower harness plate 3, so that the sliders 19 slide on the fixed shaft 17 toward the fixed block 16, and compress the second spring 18 at the same time. The slider 19 drives the connecting blocks 21 away from each other through the push rods 20 on both sides, and the connecting blocks 21 drive the two clamping blocks 22 away from each other. The clamping block 22 compresses the third spring 23, so that the clamping block 22 is separated from the slot on the clamping plate 15. Then the person takes down the upper harness plate 4 upwards through the handle 5, and then releases the slider 19. The second spring 18 pushes the slider 19 to move away from the fixed block 16. The slider 19 drives the two connecting blocks 21 to move closer to each other through the two push rods 20. The two connecting blocks 21 drive the two clamping blocks 22 to move closer to each other, and the third spring 23 stretches. Then the person removes the cable.

[0035] Example 2

[0036] This embodiment only introduces the structure that is different from the first embodiment.

[0037] like Figure 4-Figure 5 As shown, the top surface of the upper harness plate 4 is provided with two connecting plates 27, and the bottom surface of each connecting plate 27 is fixedly connected to the upper ends of the corresponding four connecting shafts 12. The top surface of the upper harness plate 4 is fixedly connected to two guide plates 26, and each guide plate 26 is rotatably connected to a threaded rod 28, which passes downward through the connecting plate 27 and is threadedly connected to the connecting plate 27, and the lower end of each threaded rod 28 is rotatably connected to the top surface of the upper harness plate 4, and the upper end of each threaded rod 28 is fixedly connected to a rotating rod 24. Two limiting rings 25 are fixedly sleeved on each threaded rod 28, and the two limiting rings 25 are rotatably connected to the top and bottom surfaces of the guide plate 26, respectively.

[0038] Working principle: After the upper harness plate 4 and the lower harness plate 3 are fixed together, when the diameter of the cable is equal to the distance between the upper clamping plate 11 and the lower clamping plate 8, there is no need to adjust the upper and lower positions of the upper clamping plate 11.

[0039] When the diameter of the cable is smaller than or larger than the distance between the upper clamping plate 11 and the lower clamping plate 8, the personnel drives the threaded rod 28 to rotate by twisting the rotating rod 24, and the two limit rings 25 on the threaded rod 28 rotate on the guide plate 26. At the same time, the threaded rod 28 drives the connecting plate 27 to move upward or downward, and the connecting plate 27 drives the corresponding four connecting shafts 12 to move upward or downward, and the connecting shafts 12 drive the corresponding two upper clamping plates 11 to move upward or downward, so that the upper clamping plate 11 and the lower clamping plate 8 can clamp cables of different diameters.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
