[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses a retractable projector mount.

[0025] Reference Figures 1-2 A retractable projector mount includes a protective frame 1, a lifting frame 2 on the protective frame 1, and a drive component 3 on the protective frame 1. The drive component 3 is used to drive the lifting frame 2 to move up and down on the protective frame 1. In use, the projector is placed on the lifting frame 2, and the protective frame 1 protects the projector.

[0026] Reference Figure 3 The protective frame 1 is installed on the wall, and a protective cavity 11 is formed inside the protective frame 1. The lifting frame 2 is embedded in the protective cavity 11 of the protective frame 1. In addition, a support plate 21 is provided on the lifting frame 2. The support plate 21 is horizontally positioned and is bolted to the lifting frame 2 during use. A placement platform 211 is formed on the support plate 21, and the projection equipment is placed on the placement platform 211 of the support plate 21. When the lifting frame 2 is stored in the protective frame 1, the protective frame 1 protects the projection equipment. When it is needed, the lifting frame 2 is lowered from the protective frame 1.

[0027] To improve the ease of lifting the lifting frame 2 on the protective frame 1, the drive assembly 3 includes a drive motor 31 and a rotating shaft 32. The rotating shaft 32 is rotatably mounted on the protective frame 1, and the drive motor 31 is also mounted on the protective frame 1. The output shaft of the drive motor 31 is connected to the rotating shaft 32. In use, the drive motor 31 drives the rotating shaft 32 to rotate. Furthermore, a connecting belt 33 is provided on the rotating shaft 32, and a slot 321 is formed on the rotating shaft 32, passing through the slot 321. One end of the connecting belt 33 passes through the slot 321 on the rotating shaft 32. The horizontal plane of the lifting frame 2 is rectangular. One end of the connecting belt 33 passing through the slot 321 is connected to one end of the lifting frame 2 along its length, and the other end is connected to the other end of the lifting frame 2 along its length. When connecting the connecting belt 33, the lifting frame 2 is lowered to the lowest end of the predetermined height, and then the two ends of the connecting belt 33 passing through the slot 321 of the rotating shaft 32 are connected to the lifting frame 2 respectively. As the drive motor 31 drives the rotating shaft 32 to rotate, the connecting belt 33 is wound on the rotating shaft 32, so that the lifting frame 2 can be raised and lowered on the protective frame 1.

[0028] Furthermore, the protective frame 1 is equipped with guide rollers 12, two of which are spaced apart on both sides of the protective frame 1 along its length. Both guide rollers 12 are rotatably mounted on the protective frame 1. The connecting belt 33 passes through the guide rollers 12. When the lifting frame 2 moves up and down on the protective frame 1 via the connecting belt 33, the guide rollers 12 guide the connecting belt 33, thereby improving the stability of the lifting frame 2 when the connecting belt 33 drives it to move up and down. In addition, it also reduces the friction between the connecting belt 33 and the protective frame 1, thus extending the service life of the connecting belt 33.

[0029] Reference Figure 3 To improve the stability of the lifting frame 2 when it is raised and lowered on the protective frame 1, a scissor arm 13 is provided between the protective frame 1 and the lifting frame 2. The scissor arm 13 is located on both sides of the length direction and one side of the width direction of the lifting frame 2, and one set is provided on each side. The scissor arm 13 includes multiple cross-connected arms. The multiple cross-connected arms are connected by hinge points. When in use, the scissor arm 13 protects the lifting frame 2, reduces the shaking of the lifting frame 2 when it is raised and lowered, and improves the protection of the projection equipment.

[0030] In actual use, projection devices come in various heights. To ensure the projection device can be placed on the support plate 21, the support plate 21 is rectangular in shape. Adjustable plates 22 are installed on the support plate 21, with one plate at each of the four corners. One end of each adjustment plate 22 is bolted to the support plate 21, and the other end extends towards the lifting frame 2. Furthermore, each of the four adjustment plates 22 has an adjustment groove 221, which is vertically oriented. Adjustable bolts 23 are installed on the lifting frame 2. These bolts pass through the adjustment grooves 221 on both the lifting frame 2 and the adjustment plates 22, and exit through the adjustment grooves 221 on the adjustment plates 22. An adjusting nut 231 is attached to the end of the adjusting bolt 23 that exits through the adjustment groove 221. The adjusting nut 231 is threaded onto the adjusting bolt 23 and presses against the adjustment plate 22. In use, the support plate 21 is adjusted along the length of the adjustment groove 221 to adjust the distance between it and the protective frame 1. After the position on the support plate 21 is adjusted, the adjustment nut 231 is rotated so that one end of the adjustment nut 231 is pressed against the adjustment plate 22.

[0031] In order to reduce the amount of external dust entering the protective frame 1 through the gap between the support plate 21 and the protective frame 1 during storage, a dustproof plate 24 is provided on the support plate 21. One end of the dustproof plate 24 is connected to the support plate 21, and the other end extends towards the side close to the protective frame 1. When the projection device is retracted, the support plate 21 is pressed against the protective frame 1, and the dustproof plate 24 blocks the horizontal gap between the support plate 21 and the protective frame 1, thereby reducing the amount of external dust entering the protective frame 1 and improving the protection of the projection device.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
