[0033] 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.

[0034] Reference Figure 1 - Figure 3The utility model provides an embodiment: a protection component for a distribution box, including a distribution box 1, which is a control center for commanding various components in the power supply line to reasonably distribute electric energy, ensuring the stable operation of the power system. It is an existing structure and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The top inner wall of the distribution box 1 is provided with an installation cylinder 2 for installing the protection component, and the outer wall of the bottom end of the installation cylinder 2 is provided with a slide groove 5 for guiding the installation ring 61. The top of the installation cylinder 2 is provided with a protection component for fixing and protecting cables of different specifications. The protection component includes a limit switch for adjusting the limit switch. The turntable 31 is at the position of the positioning plate 32, and the bottom end of the turntable 31 is rotatably connected to the bottom end of the mounting tube 2, which can improve the stability of the turntable 31 when rotating. The inner wall of the turntable 31 is slidably connected with a limit plate 32 for clamping cables of different specifications. The upper and lower ends of the limit plate 32 are fixedly connected with a slider 33 for guiding the movement of the limit plate 32. The inner wall of the turntable 31 is provided with a guide groove 34 for guiding the movement of the slider 33. The outer wall of the slider 33 is slidably connected to the inner wall of the guide groove 34. The guide groove 34 is set to an arc groove. The inner side of the limit plate 32 is provided with an anti-slip pad for increasing the friction between the cable and the limit plate, which can increase the stability of the cable when clamped.

[0035] Reference Figure 3 - Figure 5 , three groups of limit plates 32 are provided, and the three groups of limit plates 32 are evenly arranged on the center line of the turntable 31, which can increase the stability of cable clamping and can clamp cables of different specifications, thereby improving the applicability of the device. An extension plate 35 for blocking the gaps between the three groups of limit plates 32 is slidably connected to the inner wall of the limit plate 32, and limit blocks 36 for limiting the extension plate 35 are fixedly connected on both sides of the extension plate 35. A limit groove 37 for providing a movable limit for the limit block 36 is provided on the inner wall of the limit plate 32. The outer wall of the positioning block 36 is slidably connected to the inner wall of the limiting groove 37. Three groups of expansion plates 35 are provided to seal the gaps after the three groups of limiting plates 32 are unfolded, thereby preventing the invasion of external factors such as dust and moisture, protecting the cables from potential damage, and also improving the reliability of the overall installation. The inner wall of the top end of the installation cylinder 2 is fixedly connected to a slide rod 7 for guiding the movement of the limiting plate 32. The outer wall of the top end of the slide rod 7 is slidably connected to the bottom end of the limiting plate 32. The outer wall of the turntable 31 is provided with an anti-slip strip for the convenience of the operator to rotate.

[0036] Reference Figure 6 and Figure 7A limiting assembly for limiting the turntable 31 is provided on the rear side of the mounting tube 2. The limiting assembly includes a limiting rod 41 for improving the stability of the block 42 when it moves. The outer wall of the limiting rod 41 is slidably connected with a block 42 whose front end is in contact with the outer wall of the anti-slip strip. The outer wall of the bottom end of the block 42 is slidably connected to the inner wall of the mounting tube 2, and the front end of the block 42 slides on the outer wall of the anti-slip strip, which can limit the turntable 31. The rear side of the block 42 is elastically connected to the mounting tube 2 by a reset spring 43. The elastic force of the reset spring 43 enables the block 42 to be squeezed and moved by the anti-slip strip, and at the same time, the turntable 31 can be limited in the absence of external force.

[0037] Reference Figure 3 and Figure 6 The outer wall of the bottom end of the mounting tube 2 is provided with an installation component for installing the mounting tube 2, and the installation component includes a mounting ring 61 for fixing the mounting tube 2. The inner wall of the mounting ring 61 slides on the outer wall of the mounting tube 2. The inner wall of the mounting ring 61 is slidably connected with a clamping plate 62 that can be clamped on the inner wall of the clamping groove 64. The rear side of the clamping plate 62 is elastically connected to the mounting ring 61 through a compression spring 63. The elastic force of the compression spring 63 makes the clamping plate 62 stably clamped on the inner wall of the clamping groove 64. The outer wall of the front end of the mounting tube 2 is provided with a clamping groove 64 for fixing the mounting ring 61. The outer wall of the clamping plate 62 slides on the inner wall of the clamping groove 64. Two groups of clamping plates 62 and clamping grooves 64 are provided to improve the stability of the mounting ring 61 after installation.

[0038] Working principle: When the cable needs to be fixed during use, first pass the cable through the installation tube 2, then rotate the turntable 31, and while the turntable 31 is rotating, the protective strip arranged on the outer wall drives the block 42 to slide on the outer wall of the limit rod 41, and at the same time, the reset spring 43 is squeezed to release the limit of the turntable 31, and the turntable 31 rotates on the inner wall of the top of the installation tube 2, and while the turntable 31 is rotating, the slider 33 is driven to slide on the inner wall of the guide groove 34 through the guide groove 34, so that the three groups of limit plates 32 are moved inward. The limit plate 32 moves sideways to clamp the cable. While moving, the limit plate 32 slides on the outer wall of the top end of the slide rod 7 through the inner wall of the bottom end, so that the limit plate 32 moves stably. When the three groups of limit plates 32 move together, the limit block 36 is driven to slide on the inner wall of the limit groove 37, so that the expansion plate 35 enters the inner wall of the two adjacent groups of limit plates 32. At this time, the elastic force of the reset spring 43 drives the clamping block 42 to slide on the outer wall of the limit rod 41, so that the clamping block 42 limits the turntable 31, and the cable is fixed at this time.

[0039] When the device needs to be disassembled, the mounting ring 61 is rotated 90 degrees to make the card plate 62 slide out from the inner wall of the card slot 64, and the card plate 62 is squeezed by the outer wall of the mounting tube 2, so that the card plate 62 slides on the inner wall of the mounting ring 61 and squeezes the compression spring 63 at the same time. When the card plate 62 releases the slide slot 5, the mounting ring 61 can be quickly moved downward, thereby releasing the limit on the mounting tube 2. At this time, the mounting tube 2 can be removed for maintenance.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
