[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-6As shown, this utility model provides a rotating and snap-fit ​​fixing structure for a camera housing, including a camera base shell 1 and a camera outer cover 2. The camera outer cover 2 is detachably installed on the upper end of the camera base shell 1. A sleeve groove 11 is provided on the outer wall of the camera base shell 1, and the bottom end of the camera outer cover 2 is movably fitted onto the sleeve groove 11. By providing the sleeve groove 11, the camera outer cover 2 can be stably fitted onto the camera base shell 1. A groove 21 is provided on the camera outer cover 2, which facilitates the acquisition of external images by the probe element on the camera base shell 1. A guide groove 12 is provided on the bottom shell 1 of the camera. Two guide strips 22 are fixedly provided on the bottom wall of the camera cover 2. The guide strips 22 are in movable contact with the inner wall of the guide groove 12. By setting the guide groove 12 and the guide strips 22, when installing the camera cover 2, the camera cover 2 is fitted onto the bottom shell 1, and the guide strips 22 enter the guide groove 12 and are located on one side of the guide groove 12. When the camera cover 2 is manually rotated, the guide strips 22 rotate to the other side of the guide groove 12, thus completing the installation of the camera cover 2. The camera housing 2 has three locking slots 13 arranged in a ring array on its upper surface. Three locking strips 23 arranged in a ring array are fixedly installed on the inner wall of the camera housing 2. The locking strips 23 are movably fitted into the inner walls of the locking slots 13. By setting the locking slots 13 and locking strips 23, the locking strips 23 can enter the locking slots 13 during fitting. A locking groove 14 is provided on the bottom side wall of the locking slots 13. An elastic strip 24 is fixedly installed at one end of the locking strip 23. The elastic strip 24 and the inner wall of the locking groove 14 are interference-fitted. By setting the elastic strip 24 and locking groove 14, when the camera housing 2 is rotated... The elastic strip 24 revolves around and enters the locking groove 14. The elastic strip 24 deforms and is locked in place by an interference fit. The top wall of the locking groove 14 is provided with a positioning groove 15. One end of the elastic strip 24 is fixedly provided with a positioning block 25. The positioning block 25 is interference-fitted with the inner wall of the positioning groove 15. By setting the positioning block 25 and the positioning groove 15, when the camera cover 2 rotates to the position, the positioning block 25 is vertically aligned with the positioning groove 15. As the elastic strip 24 resets, the positioning block 25 is locked into the positioning groove 15, which improves the stability of the fixed camera cover 2.

[0020] An inner observation slot 16 is provided on one side of the camera base 1, and three outer observation slots 26 are provided on the inner wall of the camera cover 2. The three outer observation slots 26 are horizontally aligned with the inner observation slot 16. By setting the inner observation slot 16 and the three outer observation slots 26, when the three outer observation slots 26 are completely horizontally aligned with the inner observation slot 16, the camera cover 2 is rotated into place, and the installation of the camera cover 2 is completed.

[0021] Working principle: When it is necessary to inspect and maintain the various components inside the camera housing 1, the operator manually rotates the camera cover 2. Under the action of rotational force, the three positioning blocks 25 gradually disengage from the corresponding positioning grooves 15. At the same time, the positioning blocks 25 deform the elastic strip 24. Under the action of rotational force, the elastic strip 24 and the positioning blocks 25 gradually disengage from the locking groove 14. When the camera cover 2 is rotated to the position, the elastic strip 24 and the positioning blocks 25 completely disengage from the locking groove 14 and enter the buckling groove 13. Then, the camera cover 2 is pulled away from the camera housing 1, and the buckling strip 23, the elastic strip 24 and the positioning blocks 25 disengage from the buckling groove 13, completing the disassembly of the camera cover 2. Then, the various components inside the camera housing 1 can be inspected and maintained. During maintenance, the operator first attaches the camera housing 2 onto the camera base 1. During this process, the two guide strips 22 gradually enter the guide groove 12 and are positioned on one side of the guide groove 12. At the same time, the buckle strip 23, elastic strip 24, and positioning block 25 gradually enter the buckle groove 13. When the bottom end of the camera housing 2 contacts the fitting groove 11, the camera housing 2 is manually rotated. The elastic strip 24 and positioning block 25 gradually enter the locking groove 14. At the same time, the elastic strip 24 deforms due to the rotational force. When the positioning block 25 is vertically aligned with the positioning groove 15, the elastic strip 24 returns to its original position. The return of the elastic strip 24 causes the positioning block 25 to engage in the positioning groove 15. At this point, the camera housing 2 is fixed on the camera base 1, completing the installation of the camera housing 2.
