Technical Field

[0001] The utility model belongs to the technical field of sliding doors, and particularly relates to a sliding door that can be automatically closed. Background Art

[0002] With the improvement of people's living standards, people's requirements for the living environment are gradually increasing. Sliding doors are more and more widely used in daily life, especially in rural areas, and the application of sliding doors is becoming more and more popular.

[0003] At present, sliding doors are usually installed in sliding rails. When people enter and leave the house, they manually open the sliding door and then manually close it. Sometimes, they may forget to close the door. Especially in summer, if the sliding door is not closed for a long time, mosquitoes may enter the house, and each time the door needs to be closed, the people entering and leaving need to operate manually again, which is rather cumbersome. Content of the Utility Model

[0004] In order to solve the problems in the above background art, the utility model provides a sliding door that can be automatically closed. When people need to enter and leave, they push the two door bodies to open the sliding door. After the people entering and leaving leave, the door closing mechanism automatically makes the two door bodies move towards each other, and the two door bodies abut against each other, automatically closing the sliding door. It has the effect of not requiring the people entering and leaving to manually close the door, and the operation is relatively convenient. At the same time, it can also reduce the possibility of mosquitoes entering the room due to forgetting to close the door for a long time.

[0005] The utility model provides a sliding door that can be automatically closed, including a door frame. A pair of door bodies are slidably connected inside the door frame. A first sliding groove is provided on the upper surface of each door body, and a second sliding groove is provided on the lower surface of each door body. A first sliding rail fixedly connected to the top of the door frame and slidably connected to the first sliding groove, and a second sliding rail fixedly connected to the bottom of the door frame and slidably connected to the second sliding groove are provided. The door body is connected with a door closing mechanism.

[0006] By adopting the above technical solution, when people need to enter and leave, they push the two door bodies to open the sliding door. After the people entering and leaving leave, the door closing mechanism automatically makes the two door bodies move towards each other, and the two door bodies abut against each other, automatically closing the sliding door. It has the effect of not requiring the people entering and leaving to manually close the door, and the operation is relatively convenient. At the same time, it can also reduce the possibility of mosquitoes entering the room due to forgetting to close the door for a long time.

[0007] Furthermore, the door closing mechanism includes a pair of fixed pulleys fixedly installed on the side wall of the door frame. Each fixed pulley is connected with a wire rope. The wire ropes are cross-placed corresponding to the door bodies one by one. A first connection component is provided between the wire rope and the corresponding door body. One end of each wire rope far away from the door body is connected with a counterweight block, and a second connection component is provided between each wire rope and the corresponding counterweight block.

[0008] By adopting the above technical solution, when it is necessary to open the sliding door, when pushing the two door bodies in opposite directions, during the movement of the door bodies, the wire rope is pulled to move around the fixed pulley, and the wire rope drives the counterweight to move upward. When the people entering and leaving leave the door bodies, under the action of the counterweight, the counterweight moves downward, and the wire rope drives the two door bodies to move towards the side where they approach each other, so that the two door bodies are in contact with each other, and the sliding door is automatically closed.

[0009] Furthermore, the first connection component includes a support plate fixedly connected to the door body. A support block is fixedly connected to the upper surface of the support plate. An insertion slot is provided on the side of the support block away from the door body. The end of the wire rope is fixedly connected with an insertion rod inserted into the insertion slot.

[0010] By adopting the above technical solution, the insertion rod is inserted into the insertion slot to connect the wire rope with the door body. During the movement of the door body, the insertion rod rotates relative to the insertion slot.

[0011] Furthermore, a connection block is fixedly connected to the upper surface of the support plate. A connection slot is provided on the upper surface of the connection block. A baffle is slidably inserted into the connection slot. A spring is fixedly connected between the baffle and the bottom of the connection slot.

[0012] By adopting the above technical solution, move the baffle downward to insert the insertion rod into the insertion slot, and then release the baffle. The baffle moves upward, and the side of the baffle close to the support block abuts against the insertion rod, which has the effect of reducing the possibility of the separation of the insertion rod from the insertion slot.

[0013] Furthermore, the second connection component includes a hanging ring fixedly connected to the upper surface of the counterweight. The end of the wire rope close to the counterweight is fixedly connected with a hook connected to the hanging ring.

[0014] By adopting the above technical solution, the hook is connected to the hanging ring to connect the wire rope with the counterweight.

[0015] Furthermore, a plurality of first rollers rollingly connected to the first slide rail are installed in the first chute.

[0016] By adopting the above technical solution, the first rollers make the process of pushing the door body move more smoothly.

[0017] Furthermore, a plurality of second rollers rollingly connected to the second slide rail are installed in the second chute.

[0018] By adopting the above technical solution, the second rollers make the process of pushing the door body move more smoothly.

[0019] Furthermore, a pair of limiting blocks for the second rollers to abut against are fixedly connected to the upper surface of the second slide rail.

[0020] By adopting the above technical solution, the two door bodies move towards the side close to each other. When the two door bodies abut against each other to close the sliding door, the second roller abuts against the limiting block, and the limiting block reduces the possibility that the positions of the two door bodies deviate to one side when the two door bodies abut against each other.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] (1) When people need to enter or exit, they push the two door bodies to open the sliding door. After the people enter or exit and leave, the door closing mechanism automatically makes the two door bodies move towards each other's side, and the two door bodies abut against each other, automatically closing the sliding door. It has the effect that it does not require the people entering or exiting to manually close the door, and the operation is relatively convenient. At the same time, it can also reduce the possibility that mosquitoes enter the room due to the sliding door not being closed for a long time because of forgetting to close the door.

[0023] (2) Move the baffle downwards, insert the insertion rod into the insertion slot, and then release the baffle. The baffle moves upwards, and the side of the baffle close to the support block abuts against the insertion rod, which has the effect of reducing the possibility of the separation of the insertion rod and the insertion slot.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Next, in conjunction with the attached Figure 1 to the attached Figure 9 and specific embodiments, the present invention will be elaborated in detail.

[0037] As Figures 1 to 9 shown, a push-pull door capable of automatically closing provided by the present invention includes a door frame 1, and a pair of door bodies 2 are slidably connected inside the door frame 1. First chutes 21 are respectively provided on the upper surfaces of each door body 2, and second chutes 22 are respectively provided on the lower surfaces of each door body 2. One side of the top of the door frame 1 close to the first chute 21 is fixedly connected with a first slide rail 11, and the first slide rail 11 is slidably connected with the first chute 21. One side of the bottom of the door frame 1 close to the second chute 22 is fixedly connected with a second slide rail 12, and the second slide rail 12 is slidably connected with the second chute 22. When the two door bodies 2 are in contact with each other, the push-pull door is in a closed state.

[0038] A plurality of first rollers 23 are fixedly installed on the top of each door body 2. The first rollers 23 are placed in the first chute 21, and the first rollers 23 are in rolling connection with the first slide rail 11. A plurality of second rollers 24 are fixedly installed on the bottom of each door body 2. The second rollers 24 are placed in the second chute 22, and the second rollers 24 are in rolling connection with the second slide rail 12. When the door body 2 is pushed, the first rollers 23 and the second rollers 24 rotate, making the process of pushing the door body 2 move smoother.

[0039] The door body 2 is connected to a door closing mechanism 3. When people need to enter or exit, they push the two door bodies 2 to open the sliding door. After the people enter or exit and leave, the door closing mechanism 3 automatically makes the two door bodies 2 move towards each other. The two door bodies 2 abut against each other, automatically closing the sliding door. There is no need for the people entering or exiting to close the door manually, which is relatively convenient to operate. At the same time, it can also reduce the possibility of mosquitoes entering the room due to forgetting to close the sliding door for a long time.

[0040] The door closing mechanism 3 includes a pair of fixed pulleys 31 fixedly installed on the top side wall of the door frame 1. Each fixed pulley 31 is connected with a wire rope 32. The wire ropes 32 are arranged in one-to-one correspondence with the door bodies 2. A first connection component 33 is connected between each wire rope 32 and the corresponding door body 2. The first connection component 33 connects and fixes the wire rope 32 to the side wall of the door body 2. The two wire ropes 32 are placed crosswise.

[0041] One end of each wire rope 32 far from the door body 2 is connected with a counterweight 34. A second connection component 35 is connected between each wire rope 32 and the corresponding counterweight 34. The second connection component 35 connects and fixes the wire rope 32 to the counterweight 34.

[0042] When pushing the two door bodies 2 in opposite directions, during the movement of the door body 2, the wire rope 32 is pulled to move around the fixed pulley 31. The wire rope 32 drives the counterweight 34 to move upward, opening the sliding door. When the people enter or exit and leave the door body 2, under the action of the counterweight 34, the counterweight 34 moves downward, and the wire rope 32 drives the two door bodies 2 to move towards the side where they are close to each other, making the two door bodies 2 abut against each other, automatically closing the sliding door.

[0043] When the wire rope 32 needs to be replaced after being used for a period of time, the first connection component 33 and the second connection component 35 respectively release the restriction on the wire rope 32, and a new wire rope 32 is replaced. The first connection component 33 connects and fixes the wire rope 32 to the door body 2, and the second connection component 35 connects and fixes the wire rope 32 to the counterweight 34.

[0044] The first connection component 33 includes a support plate 331 fixedly connected to the side wall of the door body 2. A support block 332 is fixedly connected to the upper surface of the support plate 331. A plug-in slot 3321 is provided on the side of the support block 332 far from the door body 2. One end of the wire rope 32 close to the door body 2 is fixedly connected with a plug-in rod 333. The plug-in rod 333 is rotatably plugged into the plug-in slot 3321.

[0045] The plug-in rod 333 is plugged into the plug-in slot 3321 to connect the wire rope 32 to the door body 2. During the movement of the door body 2, the angle between the wire rope 32 and the fixed pulley 31 also changes accordingly. During this process, the plug-in rod 333 rotates relative to the plug-in slot 3321.

[0046] A connecting block 334 is fixedly connected to the upper surface of the support plate 331. A connecting groove 3341 is provided on the upper surface of the connecting block 334. A baffle 335 is slidably inserted into the connecting groove 3341. A pair of springs 336 are provided in the connecting groove 3341. The top ends of the springs 336 are fixedly connected to the lower surface of the baffle 335, and the ends of the springs 336 away from the baffle 335 are fixedly connected to the bottom of the connecting groove 3341.

[0047] When the insertion rod 333 needs to be inserted into the insertion groove 3321, first move the baffle 335 downward. At this time, the spring 336 is compressed. Insert the insertion rod 333 into the insertion groove 3321, and then release the baffle 335. Under the action of the spring 336, the baffle 335 moves upward. The side of the baffle 335 close to the support block 332 abuts against the insertion rod 333, and the baffle 335 blocks the insertion rod 333, reducing the possibility of the insertion rod 333 separating from the insertion groove 3321.

[0048] When the wire rope 32 needs to be replaced, move the baffle 335 downward. The baffle 335 releases the restriction on the insertion rod 333, separates the insertion rod 333 from the insertion groove 3321, then replaces the new wire rope 32, and then inserts the insertion rod 333 into the insertion groove 3321 so that the baffle 335 abuts against the insertion rod 333.

[0049] The second connection assembly 35 includes a hanging ring 351 fixedly connected to the upper surface of the counterweight 34. A hook 352 is fixedly connected to one end of the wire rope 32 close to the counterweight 34. The hook 352 is connected to the hanging ring 351 to connect the wire rope 32 to the counterweight 34. When a new wire rope 32 needs to be replaced, separate the hook 352 from the hanging ring 351, replace the new wire rope 32, and then connect the hook 352 to the hanging ring 351 to connect the wire rope 32 to the counterweight 34.

[0050] A pair of limiting blocks 121 are fixedly connected to the upper surface of the second slide rail 12. The limiting blocks 121 are arranged corresponding to the door bodies 2 one by one. When the two door bodies 2 abut against each other to close the sliding door, the second rollers 24 abut against the limiting blocks 121. When the two door bodies 2 automatically move towards the side close to each other to close the sliding door, the limiting blocks 121 reduce the possibility that the positions of the two door bodies 2 deviate to one side when the two door bodies 2 abut against each other.

[0051] The implementation principle of the sliding door that can be automatically closed provided by the present utility model is as follows: When pushing the two door bodies 2 in opposite directions, during the movement of the door bodies 2, the wire rope 32 is pulled to move around the fixed pulley 31, and the wire rope 32 drives the counterweight 34 to move upward to open the sliding door. When the people entering and leaving leave the door bodies 2, under the action of the counterweight 34, the counterweight 34 moves downward, and the wire rope 32 drives the two door bodies 2 to move towards the side close to each other, so that the two door bodies 2 abut against each other and automatically close the sliding door.

[0052] The above further describes the present utility model by means of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
