DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following is only the preferred embodiment of the present utility model, and the protection scope is not limited to this embodiment. All technical solutions falling within the concept of the present utility model shall belong to the protection scope of the present utility model. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom" and "top", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0020] As shown Figures 1 to 6 in the figure, an assembly structure of an electromagnetic shielding plate includes an electromagnetic shielding plate 1 and an electromagnetic shielding plate 2. A T-shaped groove 11 is formed at the top end of the electromagnetic shielding plate 1, and a T-shaped block 21 matched with the T-shaped groove 11 is fixedly arranged at the bottom end of the electromagnetic shielding plate 2. Through the cooperation of the T-shaped block 21 and the T-shaped groove 11, the electromagnetic shielding plate 1 and the electromagnetic shielding plate 2 can be preliminarily fixed.

[0021] A sliding groove 12 communicated with the T-shaped groove 11 is formed inside the electromagnetic shielding plate 1. A tightening mechanism 3 for pressing against the T-shaped block 21 is arranged inside the sliding groove 12. The tightening mechanism 3 includes a tightening block 31 slidably connected inside the sliding groove 12. One end of the tightening block 31 close to the T-shaped groove 11 is inclined. A tightening groove 32 matched with the tightening block 31 is formed on the T-shaped block 21. A moving rod 33 is fixedly arranged at the other end of the tightening block 31. A spring 34 is fixedly arranged between the tightening block 31 and the inner wall of the sliding groove 12. The spring 34 is wound around the moving rod 33. When an operator inserts the T-shaped block 21 of the electromagnetic shielding plate 2 into the T-shaped groove 11 of the electromagnetic shielding plate 1 and moves it inward, since one end of the tightening block 31 is inclined, when the T-shaped block 21 moves to a certain position inside the T-shaped groove 11, the tightening block 31 can be driven to slide inside the sliding groove 12. Through its sliding, not only can the spring 34 be in a compressed state, but also the moving rod 33 can be driven to move together. When the tightening groove 32 of the T-shaped block 21 is located at the tightening block 31, the elastic force of the spring 34 can drive the tightening block 31 to reset and enter into the tightening groove 32, so as to play a role in pressing against the T-shaped block 21.

[0022] A chamber 4 is formed inside the electromagnetic shielding plate 1. A moving groove 41 is formed on one side of the outer wall of the electromagnetic shielding plate 1. The moving groove 41 is communicated with the chamber 4. A moving shaft 42 is slidably connected inside the moving groove 41. A handle 43 is fixedly arranged at the end of the moving shaft 42 away from the chamber 4. The end of the moving rod 33 away from the tightening block 31 respectively penetrates through the sliding groove 12 and one end of the chamber 4 and is fixed to the moving shaft 42. When the moving rod 33 moves, the moving shaft 42 can be driven to slide inside the moving groove 41 and the chamber 4. Through the sliding of the moving shaft 42, the handle 43 can be driven to move together. When it is necessary to separate the electromagnetic shielding plate 1 and the electromagnetic shielding plate 2, the operator can drive the moving shaft 42 to move backward through the handle 43, and respectively drive the moving rod 33 and the tightening block 31 to move backward. When the tightening block 31 disengages from the tightening groove 32, the operator can take out the T-shaped block 21 of the electromagnetic shielding plate 2 from the electromagnetic shielding plate 1.

[0023] A pressing mechanism 5 for pressing the abutting mechanism 3 is provided on the first electromagnetic shielding plate 1. The pressing mechanism 5 includes a pressing block 51 located inside the chamber 4. The pressing block 51 is arc-shaped and a bolt 52 is fixedly provided at the top. An internal thread groove 53 is opened at the top of the first electromagnetic shielding plate 1. The bolt 52 is matched with the internal thread groove 53, and the internal thread groove 53 communicates with the chamber 4. When an operator rotates the bolt 52, since the bolt 52 is matched with the internal thread groove 53, the pressing block 51 can be driven to rotate downward until the pressing block 51 presses the moving shaft 42.

[0024] Working principle: When the operator installs the T-shaped block 21 of the second electromagnetic shielding plate 2 at the T-shaped groove 11 of the first electromagnetic shielding plate 1 and moves it inward, since one end of the abutting block 31 is inclined, when the T-shaped block 21 moves to a certain position inside the T-shaped groove 11, the abutting block 31 can be driven to slide into the chute 12. Through its sliding, not only can the spring 34 be in a compressed state, but also the moving rod 33 can be driven to move together. When the abutting groove 32 of the T-shaped block 21 is located at the abutting block 31, the elastic force of the spring 34 can drive the abutting block 31 to reset and enter the abutting groove 32, so as to abut the T-shaped block 21. Then rotate the bolt 52. Since the bolt 52 is matched with the internal thread groove 53, the pressing block 51 can be driven to rotate downward until the pressing block 51 presses the moving shaft 42, and further strengthen the fixation between the first electromagnetic shielding plate 1 and the electromagnetic shielding plate.

[0025] When it is necessary to disassemble the first electromagnetic shielding plate 1 and the second electromagnetic shielding plate 2, only need to reverse the rotation of the bolt 52, so that the pressing block 51 can move upward and disengage from the moving shaft 42. Then the operator drives the moving shaft 42 to move backward through the handle 43, and drives the moving rod 33 and the abutting block 31 to move backward respectively. When the abutting block 31 disengages from the abutting groove 32, the operator can take out the T-shaped block 21 of the second electromagnetic shielding plate 2 from the first electromagnetic shielding plate 1.

[0026] In the above specific embodiments, the technical problems solved, technical solutions and beneficial effects of the present invention are further described in detail. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
