DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0026] like Figures 1 to 7 As shown, a projection mobile speaker capable of storing and adjusting the elevation angle of playback comprises a main box body 1 and a storage cavity cover plate 13. A storage cavity for storing a projector 3 is provided on the upper portion of the main box body 1. The projector 3 is fixedly connected to an elevation adjustment bracket 8 by means of mounting screws 10. The elevation adjustment bracket 8 is connected to a fixed bracket 9 by means of a hand screw 1 4, a hand screw 2 5, an elevation adjustment friction film 1 6, and an elevation adjustment friction film 2 7. The fixed bracket 9 is fixed to the storage cavity cover plate 13 by means of a handle body 21, a handle fixing screw 1 11, and a handle fixing screw 2 12. Lock buckle 14 and lock buckle 2 15 are provided at both end positions of the storage cavity cover plate 13, respectively.

[0027] Among them, the lock buckle 14 is rotatably connected to the main box body 1 through the lock buckle screw 16, and the lock buckle 2 15 is rotatably connected to the main box body 1 through the lock buckle screw 2 17. The locking and loosening of the storage cavity cover 13 are achieved by rotating the lock buckle 14 and the lock buckle 2 15.

[0028] There is an opening 22 card slot on the upper part of the projector 3 storage chamber of the main box 1. The size specification of the opening 22 card slot matches the size specification of the storage chamber cover 13. It is used to place and position the projector 3 when the projector 3 is in use, and is also used to store the storage chamber cover 13 when the projector 3 is stored.

[0029] A partition is provided at the bottom of the storage cavity of the main box 1 for accommodating the projector 3, and a through hole 19 is opened on the partition. An audio and power system 2 is provided below the partition. The power cord 20 connected to the audio and power system 2 passes through the through hole 19 for connecting to the projector 3.

[0030] A mounting platform 18 is provided on the main box body 1 at a position where the storage cavity cover plate 13 is mounted, and protrudes into the inner cavity of the box body, so as to effectively support the storage cavity cover plate 13 .

[0031] An opening 22 is provided at the outer edge of the storage cavity cover 13. When using the projector, the power cord 20 is placed in the opening 22 on the storage cavity cover 13 to prevent the power cord 20 from being stuck due to the matching gap between the storage cavity cover 13 and the main box 1.

[0032] The working principle of the utility model is: the main box 1 is a speaker shell with a storage cavity for the projector 3, which is not limited to the box type, and can be in various types of box forms. The sound and power systems can independently complete the audio processing, and can be connected to the projector 3 through the projection power line 20 to provide a common power supply for the projection;

[0033] When adjusting the elevation angle, loosen the hand screw 1 4 and the hand screw 2 5, and then adjust the elevation angle adjustment bracket within a certain angle. Since the elevation angle adjustment bracket is fixedly connected to the projector 3, the elevation angle adjustment of the projector 3 is realized. After adjusting the elevation angle, tighten the hand screw 1 4 and the hand screw 2 5.

[0034] The storage cavity cover 13 is not only a storage cover, but also a support base when the projector is in use. When the projector 3 is in the storage state, the storage cavity cover 13 can be locked by rotating the lock buckle 14 and the lock buckle 2 15 fixed on the main box 1 to prevent the projector 3 in the storage state from falling off as a whole. When the projector 3 is to be used, the lock buckle 14 and the lock buckle 2 15 are rotated to the unlocked state, and then the projector 3 components are taken out. After the projector 3 components are taken out, it is necessary to first The power cord 20 in the storage cavity of the projector 3 of the main box 1 is connected to the projector 3, and the power cord 20 is connected to the internal audio and power system 2. When using the projection, the power cord 20 must be placed in the opening 22 on the storage cavity cover 13 to prevent the power cord 20 from being cut off due to the matching gap between the storage cavity cover 13 and the main box 1; the projection mobile speaker that can store and adjust the playback elevation angle provides users with the convenience of quick storage and use of the projector 3 while controlling the cost as much as possible;

[0035] The utility model adjusts the structure of the mobile speaker box and sets a storage cavity on the speaker box, so as to solve the problem of storing the projector 3 in the speaker equipment in a low-cost manner. At the same time, the speaker is used as a workbench for the projector 3. After opening the projection lock, the projection component is taken out as a whole and then placed in the card slot on the speaker. The fixed position projection is not easy to slip. The projection bracket is equipped with a projection elevation adjustable function, and the playback elevation angle of the projector 3 can be freely adjusted, which is convenient for adjusting the screen projection height. The projector 3 is used to project video files with good viewing effect. The overall structure is simple and practical.

[0036] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
