DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figures 1 to 7 , a cable fixing clamp capable of multi-stage installation, comprising: A fixing screw 1 and two right-angle ear plates 2 respectively fixedly mounted on both ends of the fixing screw 1 are provided with mounting holes, through which rivets or screws can be passed to fix the device at a designated position.

[0020] The clamping block 3 is movably mounted on the outside of the fixed screw 1, an arc-shaped clamping groove 4 is provided on the top of the clamping block 3, and a cavity 5 is provided inside the clamping block 3; two clamping components are respectively arranged on both sides of the arc-shaped clamping groove 4, and the clamping components include two frame-type rotating frames 6 rotatably mounted on the top of the clamping block 3, and the two frame-type rotating frames 6 are jointly fixedly mounted with a clamping plate 7 on one end away from the clamping block 3, and a plurality of rubber anti-slip strips 32 are fixedly mounted on the opposite side of the two clamping plates 7 and the surface of the arc-shaped clamping groove 4, which increases the friction between the cable and the contact surface of the two clamping plates 7 and the arc-shaped clamping groove 4, thereby improving the clamping firmness of the cable.

[0021] The two frame-type rotating frames 6 are commonly slidably connected with a moving shaft 8, the surface of the moving shaft 8 is fixed with a rectangular frame 9, and the other end of the rectangular frame 9 slides through the cavity 5, and one end of the rectangular frame 9 extending into the cavity 5 is threadedly connected to a screw rod 10, and the other end of the screw rod 10 is rotatably installed at the bottom of the cavity 5, and the surface of the screw rod 10 is fixedly sleeved with a driven gear 11.

[0022] The driving assembly is used to drive the two driven gears 11 to rotate synchronously in the same direction; the driving assembly includes a driving gear 12 rotatably installed at the bottom of the cavity 5, and the driving gear 12 is placed between the two driven gears 11 and meshes with both driven gears 11. The bottom of the clamping block 3 is rotatably installed with a first knob 13 coaxially connected to the driving gear 12. The diameter of the driving gear 12 is larger than the diameter of the two driven gears 11, so that when the staff turns the first knob 13, the transmission ratio between the driving gear 12 and the two driven gears 11 can be used to make it easier for the staff to control the synchronous rotation of the two screw rods 10.

[0023] The splicing assembly is used to horizontally splice and fix multiple clamping blocks 3; the splicing assembly includes two brackets 14 fixedly mounted on the top of the cavity 5, a threaded rod 15 is rotatably mounted between the two brackets 14, a worm gear 16 is fixedly mounted on the surface of the threaded rod 15, a worm 17 is engaged with the lower side of the worm gear 16, and the worm 17 is rotatably mounted in the cavity 5, a second knob 18 coaxially connected to the worm 17 is rotatably mounted on the surface of the clamping block 3, a movable plate 19 is threadedly connected to the surface of the threaded rod 15, and both ends of the movable plate 19 are slidably fitted on the inner surface of the cavity 5, two insertion rods 20 are fixedly mounted on the side of the movable plate 19 away from the worm gear 16, and the insertion rod 20 slides through to the outside of the clamping block 3, a T-shaped sliding sleeve 21 is fixedly mounted on the end of the clamping block 3 close to the insertion rod 20, and a T-shaped The two clamping blocks 3 are spliced ​​together by putting the T-shaped sleeve 21 on one clamping block 3 and the T-shaped strip 22 on the other clamping block 3, and then aligning the plug 20 with the corresponding positioning slots 23. The second knob 18 is turned, and the threaded rod 15 is driven by the worm 17 and the worm gear 16 to rotate, so that the movable plate 19 can extend the two plugs 20 under the sliding limit of the cavity 5 surface until they are inserted into the corresponding two positioning slots 23, thereby completing the splicing of the two clamping blocks 3. By analogy, the splicing between multiple clamping blocks 3 can also be realized, so that a specified number of clamping blocks can be selected according to the number of cables.

[0024] An adjustment component is used to adjust the position of the clamping block 3 on the fixed screw 1. The adjustment component includes a threaded sleeve 24 threadedly connected to the surface of the fixed screw 1. A movable sleeve 26 is movably embedded in the surface of the threaded sleeve 24. The movable sleeve 26 is fixed to the clamping block 3 through a fixed rod 27. A plurality of drive rods 25 are fixedly installed on the surface of the threaded sleeve 24, and the plurality of drive rods 25 are axially distributed, which facilitates the staff to rotate the threaded sleeve 24.

[0025] A limit assembly is provided between the clamping block 3 and the fixed screw 1. The limit assembly includes a limit block 30 slidably connected to the surface of the fixed screw 1, and the limit block 30 is fixedly installed in the limit sleeve 29. A limit groove 31 is provided on the surface of the fixed screw 1, and the limit groove 31 is slidably connected to the limit block 30. The limit sleeve 29 is fixed to the clamping block 3 through the limit rod 28. The sliding engagement between the limit groove 31 and the limit block 30 can prevent the clamping block 3 from rotating when it moves vertically.

[0026] Furthermore, the plurality of positioning grooves 23 are linearly distributed in groups of two, so that the heights of two adjacent clamping blocks 3 may be inconsistent.

[0027] The working principle of the present invention is: When in use, the threaded sleeve 24 is first rotated by the driving rod 25, so that the threaded sleeve 24 moves spirally on the fixed screw 1. At this time, the movable sleeve 26 and the fixed rod 27 support the clamping block 3, and the limiting rod 28 and the limiting block 30 in the limiting sleeve 29 are slidably engaged with the upper limit groove 31 of the fixed screw 1, so that the height of the clamping block 3 can be adjusted according to actual needs. Then, the cable is clamped into the arc-shaped clamping groove 4 on the clamping block 3, and the first knob 13 is turned to make the large gear 12 drive the two small gears 11 meshing with it to rotate synchronously in the same direction. Then, the two screw rods 10 rotate synchronously in the same direction, controlling the two rectangular frames 9 to move downward synchronously. The two moving shafts 8 slide in the corresponding frame-type rotating frames 6 respectively, pulling each frame-type rotating frame 6 to rotate downward until each clamping plate 7 rotates toward the clamping block 3 and presses against the cable, completing the clamping and fixing of the cable. Finally, when multiple cables need to be fixed, first put the T-shaped sliding sleeve 21 on one clamping block 3 onto the T-shaped bar 22 on the other clamping block 3 and slide it until it is in the specified position, then turn the second knob 18, and then under the transmission of the worm 17, worm wheel 16 and threaded rod 15, the movable plate 19 drives the two plug rods 20 to move outward until they are inserted into the corresponding positioning grooves 23, thereby completing the splicing between the two clamping blocks 3, thereby realizing multi-level installation of multiple cables.

[0028] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0029] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
