Technical Field
[0001] This utility model relates to the field of automatic door and window technology, and in particular to an automatic closing sliding door. Background Technology
[0002] With the continuous development of technology, people often encounter sliding doors that need to be opened and closed in their lives. Currently, some electric sliding doors on the market, also known as automatic sliding doors, mainly use motor units to realize the automatic opening and closing of the door. However, the cost of motor units is relatively high, and they are not suitable for installation in certain specific situations. In the event of a power outage, automatic sliding doors cannot close automatically. Furthermore, current automatic sliding doors generally do not have a buffer mechanism, so the two sides of the door are easily impacted when the automatic sliding door is closing and opening, causing damage to the door.
[0003] Therefore, based on customer feedback regarding the shortcomings of the existing device, the inventors made further improvements to overcome the aforementioned problems. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sliding door with a simple structure, convenient operation, and effective buffering to avoid collisions and automatically closing.
[0005] The purpose of this utility model is achieved through the following technical solution: an automatically closing sliding door, comprising a sliding door, a track, and a buffer part;
[0006] The sliding door is suspended by a track, with the upper edge of the sliding door inclined. The track is also installed at an incline, and the upper edge of the sliding door is adapted to the track and can slide along the track.
[0007] The buffer part includes buffer part A and buffer part B. Buffer part A is disposed on the side edge of the sliding door. Buffer part A includes a slider and a handle. The two sliders are slidably mounted on one side of the sliding door and are opposite to each other. An elastic element is provided between the sliders. The two ends of the handle are respectively connected to the two sliders. Buffer part B is movably mounted on the door frame. One end of it is connected to spring B, and the other end is facing the other side edge of the sliding door.
[0008] When in operation, the sliding door is pulled open towards the uphill side, and the other edge of the sliding door contacts the buffer part B. The buffer part B, through spring B, cushions the sliding door. After releasing the hand, due to the gravity of the sliding door itself, the sliding door automatically returns to its original position and closes along the inclined track. The buffer part A is subjected to force, causing the two sliders to move away from each other, and the handle is squeezed, thus achieving the cushioning of the sliding door.
[0009] As a preferred technical solution of this application, the track is installed at an angle of 2°, and the beginning and end of the track have a certain height difference, so that the sliding door with the same slope on the upper edge can slide smoothly down the track due to its own weight.
[0010] As a preferred technical solution of this application, the buffer part A further includes a mounting groove and a long rod; the mounting groove is fixed to the side edge of the sliding door, and a long rod is set in the mounting groove. One end of the long rod is fitted and connected to the upper inner wall of the mounting groove, and the other end is fitted and connected to the lower inner wall of the mounting groove. Slider A and slider B are respectively slidably inserted into the long rod.
[0011] As a preferred technical solution of this application, an elastic element is provided in the mounting groove. One end of the elastic element is connected to the upper inner wall of the mounting groove, and the other end is connected to the slider A. The lower inner wall of the mounting groove is also connected to the elastic element, and the other end of the elastic element is connected to the slider B. The slider A and the slider B are connected by the elastic element.
[0012] As a preferred technical solution of this application, the elastic element is a compression spring, which is sleeved on a long rod in the mounting groove.
[0013] As a preferred technical solution of this application, the handle is elastic. When the handle is subjected to pressure, it will move toward the sliding door. The sliders A and B connected at both ends of the handle will move away from each other along the long rod. When the pressure disappears, the handle will spring back, and the sliders A and B will move closer to each other to restore the handle to its original state.
[0014] As a preferred technical solution of this application, the two sets of sliding doors and their matching tracks are arranged opposite to each other to form a double-opening sliding door, and the buffer parts A of the two sets of sliding doors are arranged opposite to each other to facilitate buffering when the two sets of sliding doors slide towards each other due to gravity.
[0015] As a preferred technical solution of this application, the buffer part B includes a mounting sleeve and a buffer head; multiple mounting sleeves are fixed at equal intervals on the side of the door frame, and a spring B is provided in the mounting sleeve. The other end of the spring B is connected to the buffer head. When the sliding door is slid open to the door frame, its side edge contacts the buffer head and is buffered.
[0016] This utility model has the following advantages:
[0017] (1) It can close the door automatically;
[0018] Currently, without a motor unit, sliding doors cannot close automatically. This solution designs a sliding door that can close automatically. By setting a certain slope for both the sliding door and the track that is adapted to it, the sliding door can automatically slide down on the inclined track to achieve automatic closing. It is low in cost, simple in structure, and easy to install and operate.
[0019] (2) It can buffer the sliding door and avoid collisions;
[0020] Existing sliding doors are prone to damage or excessive noise when their sides collide with fixed surfaces or door frames during opening and closing. This solution incorporates a buffer section A on the sliding door and a buffer section B on the door frame or fixed wall to cushion the sliding door. The buffer section A, through the interaction of spring A, slider A and slider B, and the elastic handle, causes the handle to move towards the sliding door when pressure is applied, while sliders A and B move away from each other along the long rod. When the pressure disappears, the handle springs back, and sliders A and B move closer together to return the handle to its original position. The buffer section B, through spring B and a buffer head, cushions the sliding door to prevent it from colliding with the door frame. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0030] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0032] Therefore, based on the above issues, please refer to Figure 1 This utility model proposes an automatically closing sliding door to solve the problem.
[0033] See Figures 1 to 7 The present embodiment proposes an automatic closing sliding door, including a sliding door 1, a track 2, and buffer parts A and B;
[0034] Among them, see Figure 2 The sliding door 1 is suspended in the track 2 by the top hanging wheel 3 and can slide along the track 2. The upper edge of the sliding door 1 is tilted at a certain angle, and the track 2 that matches it is also tilted at a certain angle, so that the sliding door 1, which has been pulled a certain distance, can slide back to its original position under the action of gravity.
[0035] Among them, see Figure 1 and Figure 2 The buffer part A is provided on the side edge of the sliding door 1. The buffer part A includes a slider and an elastic handle 6. The two sliders are disposed opposite to each other on the side edge surface of the sliding door 1 and the sliders can slide along the side edge. An elastic element is installed between the sliders, and the two ends of the handle 6 are respectively connected to the two sliders.
[0036] Among them, see Figure 2 The buffer part B is movably mounted on the door frame 10 via spring B8. One end of its buffer head 9 is connected to spring B8, and the other end is directly opposite the other side edge of the sliding door 1 (the side edge where the buffer part A is installed).
[0037] During operation, the sliding door 1 is manually pulled uphill to the position of the door frame 10. The other edge of the sliding door 1 contacts the buffer head 9 of the buffer part B. The buffer head 9 buffers the sliding door 1. At the same time, the upper edge of the sliding door 1 tilts. Due to the weight of the sliding door 1 itself, it slides back to its original position along the tilted track 2, thus closing automatically. When closing, the handle 6 of the buffer part A on the side edge of the sliding door 1 abuts against the fixed surface and is squeezed, which drives the connected slider to move relatively away from the ground, thereby buffering the sliding door 1 and avoiding collision damage.
[0038] Currently, sliding doors 1 typically use motor units to achieve automatic opening and closing. However, motor units are relatively expensive, and without a motor unit, the door cannot close automatically. Furthermore, current sliding doors 1 lack a suitable buffer mechanism, making the sides of the sliding door 1 susceptible to damage from impacts when it slides open or closes. This solution designs a manual sliding door that eliminates the need for a motor unit for automatic closing. It primarily involves sloping the upper edge of the sliding door 1 and designing the suspended track 2 as a sloping track. The sliding door 1 can automatically return to its original position and close due to its own weight. Additionally, the door frame 10 and the side edges of the sliding door 1 are each equipped with a buffer part B and a buffer part A. The cooperation of springs, sliders, and elastic handles 6 buffers the sliding door 1, preventing it from being impacted.
[0039] In this embodiment, see Figure 2 and Figure 4 For track 2, the inclination slope of track 2 is 2°, and there is a certain height difference between the initial end and the end end of track 2. The inclination slope of the upper edge of the sliding door 1 that is adapted for hoisting is also 2°. Multiple sets of hanging wheels 3 are provided on the upper edge of the sliding door 1. The sets of hanging wheels 3 are fixed to the sliding door 1 through the mounting base. The sets of hanging wheels 3 include two pulleys and a central shaft. The two pulleys are arranged opposite each other, and the pulleys have through holes in the center. The central shaft is a T-shaped shaft. The pulleys are rotatably installed on the left and right sides of the central shaft. The lower end of the central shaft is connected to the mounting base. The two pulleys are adapted to be installed in track 2 and slide along track 2.
[0040] Furthermore, an installation slope of 2° allows the sliding door 1, designed according to this scheme, to slide smoothly down the track 2 under its own weight. If the slope is too small, there will be virtually no automatic reset effect; if the slope is too large, the automatic reset speed will be too high, which may cause a violent collision and damage to the sliding door 1.
[0041] It should be noted that the sliding door 1 used in this solution is made of tempered glass. Taking advantage of the property that objects will automatically slide down a slope, the sliding door 1 is opened and then automatically slides down and closes by gravity. This not only eliminates the need for opening devices such as motors, but also saves electricity and is environmentally friendly and energy-saving.
[0042] In this embodiment, see Figure 2 and Figure 6 For the buffer section A, the two sliders are slider A4 and slider B5. Both slider A4 and slider B5 are installed in the mounting groove 11. The mounting groove 11 is a rectangular groove that is fixedly connected to the side edge of the sliding door 1. A long rod 12 is fixedly connected in the mounting groove 11, and mounting holes with a diameter matching that of the long rod 12 are opened at the center of both slider A4 and slider B5. Slider A4 and slider B5 are inserted into the long rod 12 through the mounting frame and can slide along the long rod 12. One end of the elastic element is connected to the upper inner wall of the mounting groove 11, and the other end... One end is connected to slider A4, and an elastic element is connected to the lower inner wall of the mounting groove 11. The other end of the elastic element is connected to slider B5. Slider A4 and slider B5 are connected by another elastic element. The elastic element is a pressure spring A7, which is sleeved on the long rod 12 in the mounting groove 11 for limiting. The handle 6 connected to slider A4 and slider B5 is elastic. It can bend under force and return to a vertical state when no force is applied. The two ends of the handle 6 are connected to slider A4 and slider B5, which are placed vertically, so that the handle 6 is in the shape of an arch bridge.
[0043] Furthermore, when the handle 6 is subjected to pressure, it will move toward the sliding door 1, and the sliders A4 and B5 connected to the two ends of the handle 6 will move away from each other along the long rod 12. When the pressure disappears, the handle 6 will spring back, and the sliders A4 and B5 will move closer to each other, causing the handle 6 to return to its original state.
[0044] It should be noted that the buffer part A can not only buffer the sliding door 1 through the slider, spring A7 and handle 6, but also open the sliding door 1 by pulling it open through the handle 6 when a person pulls it. Applying force to the handle 6 is simpler than pulling the glass door directly.
[0045] Furthermore, the use of an elastic handle 6 can prevent excessive local stress on the handle 6, which is beneficial to improving the service life of the handle 6.
[0046] Furthermore, see Figure 3 Two sets of sliding doors 1 and their corresponding sliding rails are arranged opposite each other to form a double-opening manual sliding door. The buffer parts A of the two sets of sliding doors 1 are arranged opposite each other to avoid collision when they are close.
[0047] In this embodiment, see Figure 2 and Figure 7For the buffer part B, the buffer part B includes a mounting sleeve 13 and a buffer head 9; the mounting sleeve 13 is cylindrical, and multiple mounting sleeves 13 are fixed at equal intervals from top to bottom on the side of the door frame 10. A spring B8 is provided in the mounting sleeve 13, and the other end of the spring B8 is connected to the buffer head 9. The buffer head 9 is I-shaped, with a short rod connecting two circular plates. One circular plate is located inside the mounting sleeve 13, and the short rod protrudes from the surface of the mounting sleeve 13. The other circular plate is directly opposite the side edge of the sliding door 1. When the sliding door 1 is slid open to the door frame 10, its side edge contacts the circular plate of the buffer head 9 and is buffered.
[0048] It should be noted that the circular plate surface of the buffer head 9 is covered with a layer of high-density sponge to avoid damaging the sliding door 1.
[0049] When using this sliding door, the original position of the sliding door 1 is closed. When the sliding door 1 is pulled back to the position of the door frame 10, the buffer part B provided on the door frame 10 prevents the sliding door 1 from colliding with the door frame 10 when it is pulled. The buffer head 9 rests on the side edge of the sliding door 1. When the hand is released, the sliding door 1 slides down the inclined track 2 due to gravity. Finally, the two opposite sliding doors 1 close together, and the opposite buffer parts A collide with each other. Since the buffer part A has an elastic handle 6 and the handle 6 is connected to the sliding slider, the sliding door 1 is prevented from being damaged by the collision.
[0050] Current sliding doors 1 are mainly manual and electric. The latter does not require manual operation, but it needs to be equipped with multiple motor units, which are relatively expensive. However, without the control of motor units, the automatic sliding door 1 cannot achieve automatic closing. Furthermore, the existing sliding doors 1 are prone to damage or generate excessive noise due to collisions when closing and opening. The automatic closing manual sliding door in this solution mainly utilizes the characteristic of the sliding door 1 to automatically slide down the inclined track. Both the sliding door 1 and the track 2 are set with a certain inclination slope to achieve automatic closing. At the same time, a buffer part B is set in the door frame 10, and the sliding door 1 is buffered by spring B8 and buffer head 9 to avoid collision with the door frame 10. A buffer part A is set on the side edge of the sliding door 1, and the sliding door 1 is buffered by spring A7 in cooperation with the slider and elastic handle 6 to avoid collision.
[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
