DETAILED DESCRIPTION Example

[0024] refer to Figures 1 to 6The cam 14 is provided with a plurality of locking plates 16, 17 and 18. The cam 14 is provided with a plurality of locking plates 16 for locking the cam 14. The locking plates 16 are provided with a plurality of locking plates 18 for locking the cam 14. The locking plates 16 are provided with a plurality of locking plates 16 for locking the cam 14. When the second card block 8 and the second card slot 6 are not in the corresponding position, the first card block 7 can be prevented from being ejected from the first card slot 3, thereby being able to effectively clamp and fix the position of the front cover 2. Due to the presence of the rubber pad 10, the rubber pad 10 has good anti-slip and shock-absorbing capabilities, and it also has good elasticity, thereby making the position of the first card block 7 more secure. Similarly, when the front cover 2 needs to be removed, the first card block 7 is rotated to adjust the angle of the second card block 8 to a position symmetrical to the second card slot 6, and then the first card block 7 can be pulled out, thereby effectively solving the problem of inconvenience in disassembling and assembling the display housing. If one of the card blocks is damaged, the other three can also be effectively clamped and fixed to the position of the front cover 2, thereby also solving the problem of inconvenience caused by driving another part by one part.

[0025] refer to Figures 1 to 4 The rear side of the front cover 2 is fixedly connected with an inserting plate 4, which is fixedly connected to the four sides of the rear side of the front cover 2 near the corners. The front side of the rear cover 1 is provided with a slot 15 that matches the inserting plate 4, and the inserting plate 4 is inserted into the inner side of the slot 15. Due to the existence of the inserting plate 4, the insertion of the inserting plate 4 can limit the fixed point of the front cover 2 in advance, while improving the stability of the position of the front cover 2, it can also effectively improve the accuracy of the position of the front cover 2.

[0026] refer to Figures 1 to 4 A limiting groove 14 is provided on the front side of the rear cover 1, and a sealing ring 5 matching the limiting groove 14 is fixedly connected to the rear side of the front cover 2. The sealing ring 5 covers the inner side of the limiting groove 14. Due to the presence of the sealing ring 5, when the front cover 2 is snapped and fixed, the sealing ring 5 can effectively seal the connection point between the front cover 2 and the rear cover 1, thereby effectively improving the overall sealing effect.

[0027] refer to Figure 1 and Figure 4A vent 16 is provided on the front side of the back cover 1, and the vent 16 is communicated with the inner side of the back cover 1. A dustproof plate 17 is fixedly connected to the inner side of the vent 16, and the dustproof plate 17 covers the inner side of the vent 16. Due to the opening of the vent 16, the vent 16 can effectively ventilate and dissipate heat on the inner side of the back cover 1. The dustproof plate 17 can protect the inner side of the vent 16 while blocking a large amount of dust and pollutants in the circulating air, thereby preventing a large amount of dust and pollutants from entering the back cover 1, thereby effectively improving the service life of the equipment installed inside the back cover 1.

[0028] refer to Figure 1 and Figure 6 The outer side of the support 18 is fixedly connected with a fixing block 19, and the top of the fixing block 19 is in contact with the bottom end of the back cover 1. A screw hole 20 is opened at the bottom end of the fixing block 19, and the screw holes 20 all pass through the fixing block 19 and the bottom end of the back cover 1. The inner side of the screw hole 20 is threadedly connected with a bolt 21, and the top of the bolt 21 is threadedly connected to the inside of the back cover 1 through the screw hole 20. The support 18 is threadedly connected to the bottom end of the back cover 1 through the fixing block 19, the screw hole 20 and the bolt 21. Due to the existence of the support 18, the support 18 can effectively support the bottom end of the back cover 1, thereby improving the stability of the position of the back cover 1. Because the support 18 is fixed by threads, when the support 18 needs to be removed, the bolt 21 can be unscrewed out of the screw hole 20, which is also convenient for the user to perform individual maintenance on the support 18 later.

[0029] refer to Figure 6 A groove 22 is provided at the bottom end of the support 18, and a shock-absorbing pad 23 is fixedly connected to the inner side of the groove 22. The shock-absorbing pad 23 covers the inner side of the groove 22. The position of the bottom end of the shock-absorbing pad 23 is on the same horizontal line as the position of the bottom end of the support 18. Due to the presence of the shock-absorbing pad 23, the shock-absorbing pad 23 is a rubber product with good anti-slip ability and rubber shock-absorbing ability, thereby effectively improving the stability of the support 18.

[0030] refer to Figure 4 and Figure 5 A retaining spring 13 matching the first clamping block 7 is installed on the inner side of the circular groove 12. The first clamping block 7 is clamped to the inner side of the circular groove 12 through the retaining spring 13. Due to the presence of the retaining spring 13, when the first clamping block 7 is clamped into the circular groove 12, the retaining spring 13 can perform a secondary clamping and fixing of the position of the first clamping block 7, thereby further improving the stability of the clamping of the first clamping block 7.

[0031] Principle and advantages of use: When installing the front cover 2, due to the presence of the inserting plate 4, the insertion of the inserting plate 4 can limit the fixed point of the front cover 2 in advance, and then the first card block 7 and the second card block 8 are inserted into the circular groove 12 through the first card slot 3 and the second card slot 6. Then the user rotates the first card block 7 through the gripping point granted by the protrusion 11. When the position of the second card block 8 and the second card slot 6 are not corresponding to each other, the first card block 7 can avoid being ejected from the first card slot 3, thereby effectively clamping and fixing the position of the front cover 2. Due to the presence of the rubber pad 10 , its rubber pad 10 has good anti-slip and shock-absorbing capabilities, and it also has good elasticity, which can make the position of the first clamping block 7 more secure. Similarly, when the front cover 2 needs to be removed, the first clamping block 7 is rotated, the angle of the second clamping block 8 is adjusted to a position symmetrical to the second clamping slot 6, and then the first clamping block 7 is pulled out. Due to the presence of the clamping spring 13, when the first clamping block 7 is clamped into the circular groove 12, the clamping spring 13 can fix the position of the first clamping block 7 for the second time, thereby further improving the stability of the clamping position of the first clamping block 7. Qualitatively, due to the presence of the sealing ring 5, when the front cover 2 is snap-fitted and fixed, the sealing ring 5 can effectively seal the connection point between the front cover 2 and the back cover 1, thereby effectively improving the overall sealing effect. Due to the opening of the vent 16, the vent 16 can effectively ventilate and dissipate heat on the inside of the back cover 1, and the dustproof plate 17 can protect the inside of the vent 16 while also blocking a large amount of dust and pollutants in the circulating air, thereby preventing a large amount of dust and pollutants from entering the back cover 1, thereby effectively improving the installation of the inside of the back cover 1. The service life of the equipment is extended due to the presence of the support 18, which can effectively support the bottom end of the back cover 1, thereby improving the stability of the position of the back cover 1. Because the support 18 is fixed with threads, when the support 18 needs to be removed, the bolt 21 can be unscrewed out of the screw hole 20. It is also convenient for the user to perform individual maintenance on the support 18 later. Due to the presence of the shock-absorbing pad 23, the shock-absorbing pad 23 is a rubber product with good anti-slip ability and rubber shock-absorbing ability, thereby effectively improving the stability of the position of the support 18.
