[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0039] Example 1, referring to Figures 1 to 5 This is the first embodiment of the present invention. This embodiment provides a lifting mechanism, including a support member 1, on which a sliding groove 11 is provided; in this embodiment, the support member 1 is a hollow column structure.

[0040] The displacement component 2 includes a screw 21 rotatably disposed within the support component 1, and a threaded sleeve 22 threadedly connected to the outer wall of the screw 21. The threaded sleeve 22 is provided with a limiting block 23; the limiting block 23 is movably disposed within the slide groove 11.

[0041] Because the slide 11 and the limiting block 23 limit the threaded sleeve 22, when the screw 21 rotates, the threaded sleeve 22 can move up and down along the outer wall of the screw 21 to realize the lifting function of the object, which makes it easy to control the height of the object installed on the limiting block 23.

[0042] Specifically, one end of the screw 21 is provided with a rotating shaft 211; the end of the support member 1 is provided with a mounting plate 12; the screw 21 is rotatably mounted on the mounting plate 12 via the rotating shaft 211.

[0043] Furthermore, it also includes a rotating member 3 disposed on the support member 1; the rotating member 3 is used to control the screw 21 to rotate.

[0044] The outer wall of the screw 21 is provided with a first bevel gear 212; the rotating part 3 includes a turntable 31 and a rotating rod 32 provided on the turntable 31, and a second bevel gear 33 is provided at one end of the rotating rod 32.

[0045] One end of the rotating rod 32 passes through the support member 1; the first bevel gear 212 and the second bevel gear 33 mesh with each other.

[0046] In use, the user manually rotates the turntable 31, which drives the rotating rod 32 to rotate. The rotating rod 32 is rotatably mounted on the support member 1. When the rotating rod 32 rotates, the second bevel gear 33, which is fixed at the end of the rotating rod 32, will rotate together. Due to the meshing connection between the second bevel gear 33 and the first bevel gear 212, the second bevel gear 33 will drive the first bevel gear 212 to rotate. The first bevel gear 212 is fixed outside the screw 21. Therefore, the rotation of the first bevel gear 212 can drive the screw 21 to rotate inside the support member 1. The rotation of the screw 21 will cause the threaded sleeve 22 to slide up and down, realizing the lifting and lowering movement of the object located on the limiting block 23.

[0047] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a protective member 5 disposed on the support member 1. The protective member 5 is used to protect the slide groove 11 and prevent dust and rainwater from entering the interior of the support member 1 through the slide groove 11.

[0048] The slide 11 is provided with a receiving groove 13; the receiving groove 13 is symmetrically opened on both sides of the inner wall of the slide 11.

[0049] The protective component 5 includes a sliding plate 51 that is slidably disposed in the receiving groove 13, and a spring 52 disposed on the sliding plate 51, one end of the spring 52 being fixedly connected to the receiving groove 13.

[0050] The elastic force of the spring 52 causes the symmetrically arranged slide plates 51 in the receiving groove 13 to move closer to each other. Therefore, the symmetrically arranged slide plates 51 can abut against each other and close the gap in the groove 11.

[0051] Specifically, the skateboard 51 has an inclined surface 53; the limiting block 23 has a pushing surface 231.

[0052] It should be noted that the limiting block 23 is slidably disposed between the symmetrically arranged sliding plates 51. Each sliding plate 51 is provided with two symmetrically arranged inclined surfaces 53. The pushing surface 231 is used to abut against the inclined surfaces 53 to push the two mutually abutting sliding plates 51 apart.

[0053] Furthermore, the skateboard 51 is provided with a front panel 54, which is located at the slope 53. The front panel 54 can completely seal the gap formed by the slide groove 11 when the skateboard 51 collides with each other, thereby improving the dustproof and waterproof effect.

[0054] The receiving groove 13 is provided with a guide post 511, and the slide plate 51 is slidably disposed on the guide post 511. It should be noted that the slide plate 51 is provided with a corresponding guide hole at the location of the guide post 511, and the slide plate 51 is slidably connected to the guide post 511 through the guide hole.

[0055] The limiting block 23 is provided with a protective pad 232, which is slidably connected to the outer wall of the support member 1. The protective pad 232 can block the gap between the two slide plates 51 at the location of the limiting block 23, further improving the protective effect while also increasing the limiting effect on the threaded sleeve 22 and improving the stability during lifting.

[0056] The rest of the structure is the same as in Example 1.

[0057] In use, the object to be raised or lowered is mounted on the protective pad 232, and the protective pad 232 secures the object to be raised or lowered to the limiting block 23, as shown in the reference. Figure 5The limiting block 23 has symmetrically arranged pushing surfaces 231 above and below it. The limiting block 23 is positioned between symmetrically arranged sliding plates 51. When the turntable 31 is rotated to make the second bevel gear 33 rotate, the second bevel gear 33 drives the first bevel gear 212 to rotate, and the first bevel gear 212 drives the screw 21 to rotate. The rotation of the screw 21 causes the threaded sleeve 22 to slide, thereby causing the limiting block 23 to slide. During the sliding process, the limiting block 23 pushes the inclined surface 53 through the pushing surface 231, causing the sliding plates 51 in the sliding direction to expand and move away in sequence. When the sliding plates 51 lose the resistance of the limiting block 23, the symmetrically arranged sliding plates 51 will resist each other again under the elastic force of the spring 52. Due to the mutual resistance of the sliding plates 51, the slide groove 11 can be sealed, thereby improving the dustproof and waterproof effect of the support 1 and preventing dust and rainwater from damaging the equipment inside the support 1.

[0058] Example 3, referring to Figures 1-5 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a video surveillance device, including a lifting mechanism and a camera 4 disposed on the limiting block 23.

[0059] Specifically, the camera 4 is fixed on the limit block 23 by the protective pad 232.

[0060] The rest of the structure is the same as in Example 2.

[0061] When in use, the camera 4 can be raised and lowered by the lifting mechanism, which makes it easier to maintain the camera 4, reduces the difficulty and cost of maintenance, and allows the camera 4 to be lowered to the ground for operation, avoiding the risks of traditional high-altitude operations, shortening the debugging and repair time, and saving maintenance costs.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
