[0021] Please refer to Figures 1-5 , an intelligent electronic door access control box that is convenient for disassembly and assembly, including a lower box body 1 and an upper box body 2. An installation cavity 3 is provided inside the lower box body 1. Two symmetrically distributed sliding rods 4 are fixedly connected between the upper and lower end faces of the installation cavity 3. Two symmetrically distributed sliding plates 5 are slidably connected to the outer walls of the two sliding rods 4. On the left and right sides of the front end faces of the two sliding plates 5, first clamping blocks 6 are fixedly connected. Four symmetrically distributed second clamping blocks 7 are fixedly connected to the rear end face of the upper box body 2. Slots 8 matching the first clamping blocks 6 are provided on the outer walls of the four second clamping blocks 7. A connecting shaft 9 is fixedly connected between the front and rear end faces of the installation cavity 3. A rotating plate 10 is rotatably connected to the outer wall of the connecting shaft 9. Link rods 11 are hinged to the opposite sides of the upper and lower ends of the rotating plate 10. The other ends of the two link rods 11 are respectively hinged to the centers of the two sliding plates 5. Springs 12 are sleeved on the outer walls of the two sliding rods 4. The upper and lower ends of the two springs 12 are fixedly connected to the two sliding plates 5 respectively.

[0022] In this embodiment: When disassembling the upper box body 2, the pull rod 13 is pulled downward through the handle 14. The pull rod 13 drives the lower slide plate 5 to slide downward along the two slide rods 4. Further, the lower connecting rod 11 drives the rotating plate 10 to rotate clockwise. The rotating plate 10 further drives the upper slide plate 5 to slide upward along the two slide rods 4 through the upper connecting rod 11. Thus, the two slide plates 5 drive the first clamping blocks 6 on the upper and lower sides to slide away from each other, separating the first clamping block 6 from the second clamping block 7. At this time, the upper box body 2 can be removed. When installing the upper box body 2, the four second clamping blocks 7 on the rear end face of the upper box body 2 are respectively inserted into the through holes 16. By setting the front end of the first clamping block 6 as an inclined surface, during the insertion of the second clamping block 7, the first clamping block 6 is squeezed toward the upper and lower sides, thereby driving the two slide plates 5 to move away from each other along the slide rods 4 and stretching the two springs 12. When the second clamping block 7 is completely inserted into the through hole 16, the first clamping block 6 is aligned with the clamping groove 8. At this time, under the elastic force of the spring 12, the two slide plates 5 slide relatively, causing the first clamping block 6 to be clamped into the clamping groove 8 of the second clamping block 7, thus fixing the second clamping block 7, that is, fixing the upper box body 2, and completing the installation. The utility model connects the upper box body 2 and the lower box body 1 by a clamping method, which is convenient for installation and disassembly and facilitates maintenance.

[0023] As a technical optimization scheme of the utility model, a pull rod 13 is fixedly connected to the lower end face of the lower slide plate 5. The pull rod 13 extends to the outside of the lower box body 1 and is fixedly connected with a handle 14.

[0024] In this embodiment: By extending the pull rod 13 to the outside of the lower box body 1 and fixedly connecting the handle 14, it is convenient to pull the lower slide plate 5 through the handle 14, saving time and effort.

[0025] As a technical optimization scheme of the utility model, four symmetrically distributed limiting blocks 15 are fixedly connected to the rear end face of the installation cavity 3.

[0026] In this embodiment: By fixedly connecting four symmetrically distributed limiting blocks 15 to the rear end face of the installation cavity 3, it is convenient to limit the position of the slide plate 5.

[0027] As a technical optimization scheme of the utility model, four through holes 16 matching the second clamping blocks 7 are formed in the front end face of the lower box body 1.

[0028] In this embodiment: By forming four through holes 16 matching the second clamping blocks 7 in the front end face of the lower box body 1, it is convenient for the second clamping blocks 7 to be inserted into the lower box body 1 through the through holes 16.

[0029] As a technical optimization scheme of the utility model, the first clamping block 6 is L-shaped and the front end is an inclined surface.

[0030] In this embodiment: By setting the first clamping block 6 to an L shape, it is convenient for the first clamping block 6 to be clamped in the clamping groove 8 of the second clamping block 7. By setting the front end of the first clamping block 6 to be inclined, it is convenient for the second clamping block 7 to squeeze the first clamping block 6 upward and downward when the second clamping block 7 is inserted into the through hole 16.

[0031] As a technical optimization scheme of the present utility model, the installation cavity 3 is U-shaped.

[0032] In this embodiment: By setting the installation cavity 3 to be U-shaped, it is convenient to install the sliding plate 5 and the first clamping block 6 in the installation cavity 3.

[0033] The working principle and usage process of the present utility model: When disassembling the upper box body 2, pull the pull rod 13 downward through the handle 14. The pull rod 13 drives the lower sliding plate 5 to slide downward along the two sliding rods 4, and then drives the rotating plate 10 to rotate clockwise through the lower connecting rod 11. The rotating plate 10 further drives the upper sliding plate 5 to slide upward along the two sliding rods 4 through the upper connecting rod 11, so that the two sliding plates 5 drive the first clamping blocks 6 on the upper and lower sides to slide away from each other, separating the first clamping block 6 from the second clamping block 7. At this time, the upper box body 2 can be removed. When installing the upper box body 2, insert the four second clamping blocks 7 on the rear end face of the upper box body 2 into the through holes 16 respectively. By setting the front end of the first clamping block 6 to be inclined, during the insertion of the second clamping block 7, the second clamping block 7 squeezes the first clamping block 6 upward and downward, thereby driving the two sliding plates 5 to move away from each other along the sliding rods 4 and stretching the two springs 12. When the second clamping block 7 is completely inserted into the through hole 16, the first clamping block 6 is aligned with the clamping groove 8. At this time, under the elastic force of the spring 12, the two sliding plates 5 slide relatively, so that the first clamping block 6 is clamped into the clamping groove 8 of the second clamping block 7, thereby fixing the second clamping block 7, that is, fixing the upper box body 2, and completing the installation. The present utility model connects the upper box body 2 and the lower box body 1 by a clamping method, which is convenient for installation and disassembly and is convenient for maintenance.

[0034] The above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
