Detailed Embodiments

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] As Figures 1 to 7 shown, the embodiments of the present utility model include a door panel 1, a square box 2, and a handle 7. The handle 7 is arranged in the middle of the door panel 1 through a base 702, and the connecting shaft 701 on the handle 7 extends through the base 702 to the inner side of the door panel 1. A fastening step 703 is arranged on the connecting shaft 701, and a toggle 6 is connected to the fastening step 703 through a fastener 8. A square box 2 is arranged in the middle of the inner side of the door panel 1. Slide bars 5 are slidably connected to the four side edges of the square box 2. The ends of the slide bars 5 away from the square box 2 are all connected to a locking bolt 4 through a connecting bar. Lock holes corresponding to the four locking bolts 4 are arranged on the four side edges of the door panel 1. A waist-shaped hole 501 is arranged on the slide bar 5, and four pins symmetrically arranged on the toggle 6 are inserted into the waist-shaped hole 501 to drive the slide bar 5 to slide and move the locking bolt 4.

[0023] Preferably, the horizontal slide bars and the vertical slide bars among the four slide bars 5 are arranged in two layers, and their distribution is located on the front and rear sides of the toggle 6. The four pins on the corresponding toggle are divided into two groups of symmetrically arranged horizontal pins 601 and vertical pins 602. The horizontal pins 601 are located on the front side of the toggle 6, and the vertical pins 602 are located on the rear side of the toggle 6. A connecting hole 603 for the connecting shaft 701 to pass through is arranged in the middle of the toggle 6. The two side edges of the connecting hole 603 are straight edges, and the two side edges of the connecting shaft 701 at one end on the front side of the corresponding fastening step 703 are straight edges, so that the connecting shaft 701 can drive the toggle 6 to rotate.

[0024] As Figure 1 and 3 shown, at this time, the locking bolt 4 passes through the lock hole on the door panel 1 and extends to the outside of the door panel 1. This is the locked state of the door panel 1. When the door panel 1 needs to be opened, Figure 3Taking the state of the handle 7 shown as an example, the administrator rotates the handle 7 counterclockwise, causing the connecting shaft 701 to drive the paddle 6 to rotate counterclockwise. In this way, the four pull bars 5 move in the direction away from the T-shaped limiting block 502 of the square box 2. Thus, the pull bar 5 drives the bolt 4 to retract inside the door panel 1 through the connecting bar 3, enabling the door panel 1 to be opened. When the handle 7 is rotated clockwise again, the bolt 4 extends through the lock hole to the outside of the door panel 1, capable of locking the door panel 1.

[0025] Preferably, a T-shaped limiting block 502 is provided at the end of the pull bar 5 away from the connecting bar 3, for preventing the pull bar 5 from detaching from the square box 2.

[0026] Preferably, one end of the connecting bar 3 connecting the bolt 4 is L-shaped, making the bolt 4 correspond to the center of the side of the door panel 1.

[0027] Preferably, the four pull bars 5 all penetrate through the two side edges of the square box 2 in their corresponding directions, making the sliding of the pull bar 5 smoother and the sliding structure more stable.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
