[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-4The utility model provides an embodiment: a quick-detachable instrument housing that is easy to maintain, including a protective shell 1 and a shell cover 2, the four sides of the outer wall of the shell cover 2 are fixedly connected to the limiting blocks 3, the inner wall of the shell cover 2 is rotatably connected to the inner gear ring 5, the top of the four sides of the inner wall of the protective shell 1 are provided with limiting grooves 9, the upper part of the four sides of the inner wall of the protective shell 1 is provided with fixing grooves 10, the outer diameter of the pinion 6 is meshed with the sliding tooth plate 7, the fixing blocks 8 are respectively fixedly connected to the opposite end of the sliding tooth plate 7, the top of the inner gear ring 5 is fixedly connected to the first knob 4, the limiting block 3 is matched with the limiting groove 9 in shape, the fixing block 8 is matched with the fixing groove 10 in shape, the bottom end of the pinion 6 is rotatably connected to the bottom end of the inner wall of the shell cover 2, and the bottom end of the sliding tooth plate 7 is slidably connected to the bottom end of the inner wall of the shell cover 2.

[0025] Specifically, when the protective shell 1 and the shell cover 2 need to be fixed together, first align the limit block 3 on the shell cover 2 with the limit groove 9 on the protective shell 1 and insert it, so that the shell cover 2 enters the inner wall of the protective shell 1, and the limit block 3 will fall into the limit groove 9 and get stuck, then turn the first knob 4, the first knob 4 drives the inner gear ring 5 to rotate, and the inner gear ring 5 drives the pinion 6 to rotate, and the pinion 6 drives the sliding tooth plate 7 to move outward, so that the sliding tooth plate 7 moves the fixing block 8 into the fixing groove 10, so that the protective shell 1 and the shell cover 2 are fixed together. When it is necessary to disassemble, it is only necessary to rotate the first knob 4 in the opposite direction to make the sliding tooth plate 7 move inward, thereby driving the fixing block 8 to move inward, so that the fixing block 8 is separated from the fixing groove 10 on the inner wall of the protective shell 1. At this time, the protective shell 1 and the shell cover 2 can be separated, and finally it is realized that the protective shell 1 and the shell cover 2 can be easily disassembled, making maintenance more convenient and quick, saving time and energy.

[0026] A wire harness tube 11 is fixedly connected to the right end of the protective shell 1, a fixed arc plate 15 is fixedly connected to the bottom end of the threaded rod 12, a second knob 13 is fixedly connected to the top of the threaded rod 12, fixed rods 14 are fixedly connected to the left and right sides of the top of the fixed arc plate 15, a fixed rubber pad 16 is fixedly connected to the bottom end of the inner wall of the wire harness tube 11, and the outer wall of the fixed rod 14 is slidably connected to the left and right sides of the inner wall of the top of the wire harness tube 11 respectively.

[0027] Specifically, first, the cables to be used are passed through the cable bundle tube 11 into the protective shell 1, and then the second knob 13 is rotated. The second knob 13 drives the threaded rod 12 to rotate, so that the threaded rod 12 moves downward, thereby driving the fixed arc plate 15 to move downward. The fixed rods 14 on the left and right sides of the top of the fixed arc plate 15 ensure the stability of the fixed arc plate 15 moving downward. When the fixed arc plate 15 moves downward, the cable is pressed on the fixed rubber pad 16. The fixed rubber pad 16 can provide a certain buffering and fixing effect, and finally the cables of different thicknesses can be fixed and protected.

[0028] Working principle: When in use, pass the cable to be used through the cable tube 11 into the protective housing 1, and then rotate the second knob 13. The second knob 13 drives the threaded rod 12 to rotate, causing the threaded rod 12 to move downward, thereby driving the fixed arc plate 15 to move downward. The fixing rods 14 on the left and right sides of the top of the fixed arc plate 15 ensure the stability of the downward movement of the fixed arc plate 15. When the fixed arc plate 15 moves downward, it presses the cable against the fixed rubber pad 16 to prevent the cable from loosening. Then, align the limit block 3 on the shell cover 2 with the limit groove 9 on the protective housing 1 and put it in, so that the shell cover 2 enters the inner wall of the protective housing 1, and the limit block 3 is stuck in the limit groove 9. Then rotate the first knob 4. The first knob 4 drives the internal gear ring 5 to rotate, thereby driving the small gear 6 to rotate, and further driving the sliding tooth plate 7 to move outward, so that the sliding tooth plate 7 moves the fixed block 8 into the fixed groove 10, fixing the protective housing 1 and the shell cover 2 together. When it needs to be disassembled, just rotate the first knob 4 in the reverse direction, so that the sliding tooth plate 7 drives the fixed block 8 to disengage from the fixed groove 10 on the inner wall of the protective housing 1. At this time, the protective housing 1 and the shell cover 2 can be separated.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
