In order to enable the first sliding door 1d and the second sliding door 1e to be connected, fixed or opened, the front and rear sides of the first sliding door 1d and the second sliding door 1e are fixedly connected with handles 3, the right side of the locking block 2a is plug-connected with the surface of the protrusion 2b, and a cavity 4 is opened inside the locking block 2a, and a positioning component 5 and a moving component 6 are respectively arranged inside the cavity 4. The positioning component 5 and the moving component 6 are used in combination. The first sliding door 1d and the second sliding door 1e are both located on the front side of the two glass doors 1c, and the first sliding door 1d and the second sliding door 1e are connected. By using the positioning component 5 inside the cavity 4, the first sliding door 1d can be connected and fixed with the second sliding door 1e. By using the moving component 6 inside the cavity 4, the first sliding door 1d and the second sliding door 1e can be separated. In order to enable the locking block 2a and the protrusion 2b to be plugged and connected and fixed, the positioning component 5 includes two positioning blocks 501, two return springs 502 and two short rods 503. The surfaces of the two positioning blocks 501 are movably connected to the inside of the cavity 4, and the sides of the two positioning blocks 501 close to the two return springs 502 are fixedly connected to the two return springs 502. The opposite sides of the two return springs 502 are respectively fixedly connected to the right sides of the top and bottom of the inner wall of the cavity 4, and the opposite sides of the two short rods 503 are connected to the two The front side of the positioning block 501 is movably connected. Through the positioning assembly 5, the two positioning blocks 501 can be moved from the inside of the cavity 4 to the inside of the protrusion 2b. The two return springs 502 both play a fixing and rebounding role, so that the two positioning blocks 501 and the two short rods 503 can automatically rebound to their original positions after moving. In order to make the locking block 2a disengage from the protrusion 2b, the moving assembly 6 includes a pull rod 601, a movable block 602, two rotating rods 603, a support block 604 and two elastic springs 605. The surfaces of the pull rod 601 and the movable block 602 are both movably connected to the inside of the cavity 4. The right side of the pull rod 601 is fixedly connected to the left side of the movable block 602. The insides of the two rotating rods 603 are both movably connected to the front side of the movable block 602 and in close contact.The front side of the support block 604 is movably connected to the left side of the inside of the two rotating rods 603, the left side of the support block 604 is fixedly connected to the left side of the inner wall of the cavity 4, the left sides of the two elastic springs 605 are fixedly connected to the left side of the inner wall of the cavity 4, the right sides of the two elastic springs 605 are fixedly connected to the left side of the movable block 602, and the right sides of the two rotating rods 603 are movably connected to the opposite ends of the two short rods 503. By moving the component 6, the two positioning blocks 501 can be moved out from the inside of the protrusion 2b, and the two elastic springs 605 play a role in The fixing and rebounding effects enable the movable block 602, the pull rod 601 and the two rotating rods 603 to automatically rebound to their original positions after being moved. In order to make the two positioning blocks 501 move better, the left side of the two positioning blocks 501 is slidably connected with a long board 7, and the top and bottom of the long board 7 are respectively fixedly connected to the top and bottom of the inner wall of the cavity 4. Through the use of the long board 7, the two positioning blocks 501 can only move upward or downward inside the cavity 4. In order to make the first sliding door 1d and the second sliding door 1e better used, the first sliding door 1d and the second sliding door 1e are better used. The top and bottom of the door 1d and the second sliding door 1e are fixedly connected to two pulleys 8, and the interiors of the two limiting blocks 1f are provided with two slide grooves 9 and are slidably connected to the multiple pulleys 8.

[0024] The working principle of this utility model:

[0025] When the first sliding door 1d and the second sliding door 1e need to be opened, the pull rod 601 is pulled to the left by manpower and the movable block 602 is moved to the left. The movement of the movable block 602 to the left will rotate the two rotating rods 603, so that the two rotating rods 603 will rotate with the supporting block 604 as the center of the circle, so that the right sides of the two rotating rods 603 will rotate in opposite directions, thereby making the two short rods 503 move in opposite directions and drive the two positioning blocks 501 to move, so that the two positioning blocks 501 are moved out from the inside of the protrusion 2b, so that the first sliding door 1d and the second sliding door 1e can be moved in opposite directions, and will move through multiple pulleys 8, and multiple anti-collision pads 10 will reduce the impact force, so as to realize the opening of the first sliding door 1d and the second sliding door 1e. For the second sliding door 1e, after the first sliding door 1d and the second sliding door 1e are connected, the locking block 2a and the protrusion 2b are connected, and the movable block 602 moves to the left, which will cause the two elastic springs 605 to be deformed. After the pull rod 601 is released, the movable block 602 will drive the pull rod 601, the two rotating rods 603 and the two short rods 503 to rebound to their original positions under the elastic action of the two elastic springs 605. The two positioning blocks 501 will cause the two reset springs 502 to be deformed during the movement. When the pull rod 601 is released, the two reset springs 502 will rebound to the inside of the protrusion 2b under the elastic action of the two reset springs 502, thereby fixing the locking block 2a and the protrusion 2b, thereby fixing the first sliding door 1d and the second sliding door 1e.
