[0025] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail through specific embodiments below.

[0026] The present invention discloses a fixing structure for a box body and a power supply of an LED display screen, including a box body rear cover 1, a power supply 2, a limiting member and a screw 3;

[0027] Installation steps 12 are arranged on the left and right in the cavity 11 of the box body rear cover 1, and an installation groove 13 for the power supply 2 to cooperate is between the installation steps 12;

[0028] The power supply 2 is embedded in the installation groove 13;

[0029] The limiting member is fixedly opposed to the upper surface of the power supply 2, and its side extends horizontally towards the installation step 12 and is locked and fixed on the upper surface of the installation step 12 through the screw 3.

[0030] Through the above solution, the present invention realizes the pre-positioning of the power supply 2 through the installation groove 13 between the installation steps 12 arranged in the box body rear cover 1, which is convenient for aligning holes when locking the screw 3 subsequently; the limiting member fixedly opposed to the upper surface of the power supply 2 is locked and fixed on the upper surface of the installation step 12 through the screw 3, and the locking height of the screw 3 is raised and no longer lower than the upper surface of the power supply 2, making it easier to operate. Whether using a screw machine with existing technology or manually using an electric screwdriver, the production efficiency can be improved.

[0031] In some embodiments of the present invention, the above-mentioned limiting member can be integrally formed with the power supply 2 (see the second embodiment below), or can be a fitting directly pressed on the upper surface of the power supply 2 (see the first embodiment below), or can also be a fitting indirectly pressed on the upper surface of the power supply 2 (see the third embodiment below).

[0032] In some embodiments of the present invention, the above-mentioned limiting member can be directly locked on the installation step 12 (see the first and second embodiments below), or can be indirectly locked on the installation step 12 (see the third embodiment below).

[0033] The following are specific embodiments of the present invention.

[0034] See Figure 1, showing the first embodiment of the present utility model.

[0035] In the first embodiment, the above-mentioned limiting member is a flat pressing strip 4, which requires no additional processing except for punching, and the process is simple; the upper surface of the installation step 12 is flush with the upper surface of the power supply 2. Coaxial first through holes 41 and screw holes 121 are provided at corresponding positions of the pressing strip 4 and the installation step 12. The screw 121 passes through the first through hole 41 and is threadedly connected to the screw hole 121. The pressing strip 4 is tightly fitted on the upper surface of the power supply 2 to press the power supply 2 into the installation groove 13, and no additional connection and fixing structure is required between it and the power supply 2.

[0036] Furthermore, the inner wall of the above-mentioned installation groove 13 is in clearance fit with the outer wall of the power supply 2, and a protrusion 131 protruding towards the outer wall of the power supply 2 is provided on the inner wall of the installation groove 13. The protrusion 131 abuts against the outer wall of the power supply 2. The clearance fit can ensure that there is a certain gap between the installation groove 13 and the power supply 2 so that the power supply 2 can be conveniently inserted into the installation groove 13, and the provision of the protrusion 131 can provide limitation at local positions to prevent the power supply 2 from shaking left and right after installation.

[0037] See Figure 2 , showing the second embodiment of the present utility model.

[0038] In the second embodiment, the above-mentioned limiting member is wing plates 21 integrally formed on both sides of the power supply 2. The lower surface of the wing plates 21 is attached to the upper surface of the installation step 12. Coaxial second through holes 211 and screw holes 121 are provided at corresponding positions of the wing plates 21 and the installation step 12. The screw 3 passes through the second through hole 211 and is threadedly connected to the screw hole 121. By integrally forming the wing plates 21 directly on the power supply 2, no additional accessories such as pressing strips are required when installing the power supply 2, which can save installation steps and the number of screws 3 used, reduce costs, and at the same time is suitable for automatic locking and can perform operations quickly, improving production efficiency.

[0039] See Figure 3 , showing the third embodiment of the present utility model.

[0040] In the second embodiment, the above-mentioned limiting member is a HUB board 5; a stud 122 is provided on the installation step 12. The copper post 22 of the power supply 2 (the copper post 22 is a connector at the output end of the power supply 2) and the stud 122 are both locked and fixed to the HUB board 5 by screws 3. Since the HUB board 5 is locked and fixed to the stud 122 of the installation step 12, the copper post 22 of the power supply 2 not only plays a role in electrically connecting to the HUB board 5, but also can be pressed downward by the HUB board 5 so that the power supply 2 is fixed in the installation groove 12.

[0041] Further, the upper surface of the above-mentioned mounting step 12 is higher than the upper surface of the power supply 2, and a flange 132 is formed by protruding from the inner wall of the mounting groove 13 and fitting on the edge of the upper surface of the power supply 2. An inverted L-shaped structure is formed between the flange 132 and the inner wall of the mounting groove 13, which can prevent the power supply 2 from shaking up and down.

[0042] At the same time, a groove 23 is provided at the bottom of the above-mentioned power supply 2, and a positioning block 133 is provided at the bottom of the mounting groove 13 and fitted in the groove 23. The setting of the positioning block 133 can prevent the power supply 2 from moving back and forth (or left and right) in the positioning groove 13.

[0043] In addition, the above-mentioned HUB board 5 is provided with a third through hole 51 opposite to the stud 122 or the copper post 22, and the screw 3 is passed through the third through hole 51 and threadedly connected to the stud 122 or the copper post 22.

[0044] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present invention.
