[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-5 As shown, the utility model provides a technical solution for a multi-purpose projector packaging box:

[0023] Reference Figure 1As shown, a multi-purpose projector packaging box includes a box body 1, the interior of the box body 1 is set to be hollow, the top surface of the box body 1 is open, and telescopic rods 101 are set at the four corners of the inner bottom surface of the box body 1. It should be noted that the telescopic rods 101 pass through the bottom surface of the box body 1. Figure 2 As shown, the telescopic rod 101 can be retracted into the box body 1, and accordingly, the telescopic rod 101 can be extended out of the bottom surface of the box body 1, referring to Figure 1 and Figure 2 As shown, the bottom end of the telescopic rod 101 is threadedly connected to the foot 102. It should be noted that the outer side of the bottom end of the telescopic rod 101 is provided with an external thread, and the foot 102 is set in a circular shape, and the inner side thereof is provided with an internal thread, thereby realizing the threaded connection between the foot 102 and the telescopic rod 101. When using this device, the level of the top surface of the box body 1 can be adjusted by rotating the foot 102. When the telescopic rod 101 is in the retracted state, refer to Figure 2 As shown, the feet 102 are still outside the bottom surface of the box body 1, thereby acting as pads when the box body 1 is placed, preventing the bottom surface of the box body 1 from directly contacting the ground and causing it to be worn.

[0024] Reference Figure 2 As shown, an X-direction level 2 is provided on the front side wall of the box 1, and a Y-direction level 201 is provided on the right side wall of the box 1. It should be noted that the X-direction level 2 and the Y-direction level 201 are used to measure the horizontality of the box 1. The specific measurement principle is the existing technology and will not be elaborated on here. The top surface of the box 1 is provided with a top cover 103 through a locking mechanism.

[0025] It should be noted that the top cover 103 is rigid to prevent deformation caused by placing the projector for a long time.

[0026] Reference Figure 2 and Figure 5 As shown, the locking mechanism includes a bottom block 3 fixedly connected to the top surface of the telescopic rod 101, the top of the bottom block 3 is rotatably connected to the semi-arc block 301 through a rotating shaft 302, and a mounting opening 104 is opened on the top cover 103 directly above the bottom block 3.

[0027] Among them, reference Figure 5 As shown, in an optional embodiment, a through hole 303 is provided on the side wall of the semi-arc block 301. It should be noted that the setting of the through hole 303 allows the box 1 to be easily lifted by passing a rope in the prior art through the through hole 303 after the top cover 103 is locked on the box 1, making the device more convenient when carrying the projector.

[0028] Reference Figure 4 and Figure 5As shown, the cross-sectional shape of the mounting opening 104 is the same as the bottom shape of the semi-arc block 301, so that the semi-arc block 301 can pass through the mounting opening 104. It should be noted that the semi-arc block 301 can be stuck on the top surface of the top cover 103 after rotation, thereby limiting the opening of the top cover 103.

[0029] Through the arrangement and cooperation of the box body 1, the telescopic rod 101 and the foot 102, etc., the X-direction level 2 and the Y-direction level 201 are utilized to assist the foot 102 in fine-tuning the levelness of the box body 1. At the same time, the top cover 103 can be locked by rotating the semi-arc block 301, thereby successfully realizing that the box body 1 can be used for packaging and carrying the projector, and can also serve as a dedicated placement rack at any time. The device is easy to operate, low in cost, easy to carry, and suitable for promotion and use in the field of projector packaging.

[0030] Among them, it should be supplemented that the top surface of the bottom block 3 and the bottom surface of the top cover 103 are in contact with each other, and the vertical projection of the installation port 104 is located inside the top surface of the bottom block 3. Through such a setting, dust and the like outside the box body 1 cannot enter the interior of the box body 1 from the installation port 104, thereby improving the airtightness of the device. The distance between the bottom block 3 and the semi-arc block 301 is equal to the thickness of the top cover 103, which facilitates the rotation of the semi-arc block 301 and makes the bottom surface of the semi-arc block 301 fit with the top surface of the top cover 103, making the locking of the top cover 103 more secure.

[0031] Working principle: When using this device to pack or carry a projector, you only need to place the projector in the box 1, then adjust the telescopic rod 101 to the retracted state, rotate the semi-arc block 301 to adjust its position, so that the semi-arc block 301 can pass through the installation port 104, at this time, place the top cover 103 on the top surface of the box 1, during this process, the semi-arc block 301 will pass through the installation port 104, the user only needs to rotate the semi-arc block 301 here, the semi-arc block 301 can be stuck on the top surface of the top cover 103, and then lock the top cover 103, the user can also use the rope in the existing technology to pass through the through hole 303, so that the box 1 can be easily lifted, making this device more convenient when carrying the projector.

[0032] This device can also be used as a dedicated placement stand. You only need to adjust the length of the telescopic rod 101 as required, and then fine-tune the level of the box 1 according to the X-direction level 2 and the Y-direction level 201. Fine-tuning can be done by rotating the foot 102 and adjusting its position at the bottom end of the telescopic rod 101. When the levelness of the box 1 meets the requirements, the projector can be placed on the top surface of the top cover 103, which is convenient to operate.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
