Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, and in particular to a revolving door slide rail. Background Technology

[0002] As a type of hardware accessory, drawer slides are mainly used in drawers or shelves to enable their extension and retraction. With technological advancements and changing consumer demands, a new type of drawer slide has emerged: the rotary door slide. Rotary door slides are primarily used in storage cabinets such as wardrobes and refrigerator cabinets. They are installed on opposite sides of the cabinet, with hinges connecting them to the cabinet doors. After opening the door, it can be pushed inwards along the sliding direction of the rotary door slide, allowing it to be hidden away from the cabinet wall and preventing it from obstructing passageways. However, during the sliding process, the cabinet door is prone to horizontal swaying, resulting in uneven extension and retraction, leading to decreased user satisfaction. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rotary door slide rail, which can improve the smoothness of cabinet door sliding and prevent horizontal swaying during the extension and retraction of the cabinet door.

[0004] This utility model embodiment provides a revolving door slide rail, which includes:

[0005] The slide rail body has two components, which are symmetrically arranged in the vertical direction. Each slide rail body includes a fixed component, a sliding component, and a hinge. The sliding component is slidably connected to the fixed component in a first direction. The hinge axis extends in the vertical direction. The hinge is located on the side of the sliding component away from the fixed component in a second direction. One end of the hinge is connected to the sliding component, and the other end of the hinge is a connection end for connecting to the cabinet door. The slide rail body has an extended state and a retracted state.

[0006] Two guide wheels are provided, each corresponding to one of the two slide rail bodies. The guide wheels and the slide rail bodies are spaced apart along a second direction. The central axis of the guide wheels extends along the vertical direction. The guide wheels have an outer peripheral surface for rolling contact with the cabinet door. When the slide rail body is in the extended state, the guide wheels have a rolling trajectory that is tangent to the rotation trajectory of the cabinet door. The first direction, the second direction, and the vertical direction are perpendicular to each other.

[0007] The rotary door slide rail according to the embodiment of this utility model has at least the following beneficial effects: Two slide rail bodies are symmetrically arranged in the vertical direction, and are connected to the upper and lower parts of the cabinet door respectively by hinges of the two slide rail bodies, allowing the cabinet door to rotate stably under the action of the hinges and to move linearly along the first direction following the two sliding components, so as to achieve the cabinet door being hidden and stored on one side of the cabinet along the second direction; moreover, guide wheels are added to cooperate with the slide rail bodies, and the rolling trajectory of the guide wheels is tangent to the rotation trajectory of the cabinet door when the slide rail bodies are in the extended state. When the cabinet door rotates 90° to the open position, the outer circumferential surface of the guide wheel contacts the surface of the cabinet door, thereby positioning the cabinet door and ensuring that the cabinet door is parallel to the first direction, avoiding excessive rotation of the cabinet door. Then, as the cabinet door moves with the sliding assembly, the outer circumferential surface of the guide wheel always rolls in contact with the surface of the cabinet door, so that the cabinet door can move stably along the first direction under the guidance of the guide wheel, preventing the cabinet door from swinging in the second direction when moving along the first direction, thereby improving the smoothness of the cabinet door's sliding during extension and retraction.

[0008] In some embodiments of this utility model, each of the slide rail bodies further includes a first roller, a second roller, and a steel wire rope. The fixing component is provided with a first roller and a second roller at opposite ends along a first direction.

[0013] In some embodiments of this utility model, the limiting protrusion is arc-shaped when viewed along the second direction, and the limiting protrusion is disposed on the fixing component.

[0014] In some embodiments of this utility model, the guide wheel is rotatably mounted on the fixing component, and the guide wheel is located on the side of the fixing component away from the other fixing component in the vertical direction.

[0015] In some embodiments of the present invention, the fixing component is provided with a groove extending along a first direction, a ball assembly is provided in the groove, the sliding component is movably connected to the ball assembly, and the sliding component is configured to slide relative to the ball assembly along the extension direction of the groove.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] In the description of this utility model, it should be understood that features specified as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The following is for reference. Figures 1 to 4 The description pertains to a rotary door slide rail provided according to an embodiment of the present invention.

[0027] like Figures 1 to 4 As shown, the rotary door slide rail according to this embodiment of the present invention can be used in storage cabinets, such as wardrobes, refrigerator cabinets, washing machine cabinets, etc., and can realize the cabinet door being hidden and retracted when open, avoiding the cabinet door occupying aisle space for a long time and making it convenient for people to walk in the aisle. The rotary door slide rail of this embodiment can improve the smoothness of the cabinet door sliding and prevent the cabinet door from easily swinging horizontally during the extension and retraction process.

[0028] The revolving door slide rail has a first direction, a second direction, and a vertical direction, wherein the first direction, the second direction, and the vertical direction are perpendicular to each other. In this embodiment, it is assumed that the first direction is the front-back direction and the second direction is the left-right direction.

[0029] The structure of the revolving door slide rail includes a slide rail body and guide wheels 300.

[0030] The drawer slide has two main slide rails, symmetrically arranged vertically. In a double-opening storage cabinet, two slide rails are installed on each of the left and right side walls, outside the cabinet's internal cavity. The cabinet door connects to the slide rails, allowing it to open and close. After opening, a pushing force can be applied to the door in a specific direction, causing it to slide along the slide rails and be concealed on the left or right side of the cabinet. The internal cavity can be used to store clothes, a refrigerator, a washing machine, or a dryer. The slide rails have extended and retracted positions. For a single-opening storage cabinet, only two slide rails need to be installed on the left or right side wall.

[0031] Each slide rail body includes a slide rail assembly 100 and a hinge 200. The hinge 200 serves as a connecting bridge between the slide rail assembly 100 and the cabinet door. The cabinet door can swing clockwise or counterclockwise around the hinge axis of the hinge 200. Moreover, the hinge 200 is mounted on the slide rail assembly 100, and the hinge 200 can drive the cabinet door to move in a first direction under the sliding action of the slide rail assembly 100.

[0032] The slide rail assembly 100 includes a fixed assembly 110, a ball bearing assembly 120, and a sliding assembly 130. The fixed assembly 110 is mounted on the side wall of the cabinet to provide support for the sliding assembly 130, the hinge 200, and the cabinet door. The sliding assembly 130 is slidably connected to the fixed assembly 110 along a first direction via the ball bearing assembly 120. Specifically, the fixed assembly 110 has a slide groove extending along the first direction, and the ball bearing assembly 120 is disposed within the slide groove. The sliding assembly 130 is movably connected to the ball bearing assembly 120, and the sliding assembly 130 is configured to slide relative to the ball bearing assembly 120 along the extension direction of the slide groove, allowing the sliding assembly 130 to slide back and forth between the two ends of the fixed assembly 110 along the first direction.

[0033] It is understandable that providing the ball assembly 120 between the fixed component 110 and the sliding component 130 can reduce the motion resistance of the sliding component 130. In some examples, the ball assembly 120 is fixed relative to the fixed component 110. In other examples, the ball assembly 120 is movably connected to the fixed component 110, and the ball assembly 120 can move relative to the fixed component 110 along a first direction. This reduces the size of the ball assembly 120 along the first direction. In this case, during the movement of the sliding component 130 along the first direction, the ball assembly 120 will also move along the first direction. Of course, it is not excluded that in other embodiments, the sliding component 130 achieves its slidable connection with the fixed component 110 through a sliding block and groove mating structure.

[0034] The hinge axis of hinge 200 extends vertically, and hinge 200 is located on the side of sliding assembly 130 away from fixed assembly 110 along the second direction, thus enabling a fixed connection between the cabinet door and hinge 200. One end of hinge 200 can be fixedly connected to sliding assembly 130 by screws, and the other end of hinge 200 is a connecting end for connecting to cabinet door, which is also fixedly connected to cabinet door by screws.

[0035] In a specific embodiment, such as Figures 1 to 4 As shown, the fixing assembly 110 includes an outer rail, a first mounting plate 141, and a second mounting plate 142. The length of the outer rail extends along a first direction. The first mounting plate 141 and the second mounting plate 142 are respectively disposed at opposite ends of the outer rail along the first direction. Both the first mounting plate 141 and the second mounting plate 142 are provided with mounting holes to securely connect them to the outer wall of the cabinet using screws. The outer rail is provided with a groove for installing the ball bearing assembly 120. The shape and size of the first mounting plate 141 and the second mounting plate 142 are not limited.

[0036] The ball assembly 120 includes balls and a ball holder. Multiple balls are provided on the upper and lower parts of the ball holder. The ball holder is placed in the groove of the outer rail. The length of the ball holder is smaller than the length of the groove. The balls roll in contact with the side wall of the groove. The ball holder can drive the balls to move relative to the outer rail in a first direction.

[0037] The sliding assembly 130 includes an inner rail and a sliding seat. The inner rail is placed inside the ball cage and rolls in contact with the balls. The inner rail is fixedly connected to the sliding seat, thus the inner rail and the sliding seat can move relative to the ball cage in a first direction. The movement distance of the sliding seat is less than or equal to the length of the groove. The fixed assembly 110, the ball assembly 120, and the sliding assembly 130 are all made of metal materials such as iron or aluminum.

[0038] Understandably, if the cabinet's receiving cavity opening faces forward, the second mounting plate 142 is located at the front end of the outer rail, and the first mounting plate 141 is located at the rear end of the outer rail. When the sliding assembly 130 moves backward into position, the slide rail body is in a retracted state, at which point the cabinet door connected to the slide rail body can be hidden away. When the sliding assembly 130 moves forward into position, the slide rail body is in an extended state, at which point the cabinet door connected to the slide rail body extends out and is located in the aisle, allowing people to rotate and close the cabinet door.

[0039] Two guide wheels 300 are provided, and each guide wheel 300 is respectively configured to correspond to two slide rail bodies. Each guide wheel 300 and its corresponding slide rail body are arranged at a certain interval along a second direction. The central axis of the guide wheel 300 extends in the vertical direction, and the guide wheel 300 has an outer peripheral surface for rolling contact with the cabinet door. The guide wheel 300 can guide the linear movement of the cabinet door, making the cabinet door move more smoothly along the first direction. Furthermore, the guide wheel 300 is positioned close to the second mounting plate 142. When the slide rail body is in the extended state, the guide wheel 300 has a rolling trajectory that is tangential to the rotation trajectory of the cabinet door.

[0040] Understandably, viewed vertically, the rolling trajectory of the guide wheel 300 is circular. The cabinet door rotates around the hinge axis of the hinge 200, and the rotation trajectory of the cabinet door is tangent to the rolling trajectory of the guide wheel 300. That is, during the process of switching the cabinet door from the closed state to the open state, the cabinet door rotates 90° under the action of external force, making the surface of the cabinet door with the handle parallel to the first direction. At this time, the surface of the cabinet door with the handle contacts the outer peripheral surface of the guide wheel 300, thereby limiting the swing amplitude of the cabinet door and ensuring that the cabinet door can rotate exactly 90° when it is opened, completing the positioning work of the cabinet door. This makes it convenient for people to apply a pushing action along the first direction to the cabinet door, so that the hidden side of the cabinet door can be tucked into one side of the cabinet body along the left and right direction.

[0041] As the cabinet door moves along the first direction with the slide rail body, the outer circumferential surface of the guide wheel 300 remains in contact with the surface of the cabinet door. The guide wheel 300 will roll due to the frictional force of the cabinet door. At this time, the rolling friction between the guide wheel 300 and the cabinet door is small, which can prevent damage to the surface of the cabinet door.

[0042] The thickness of the guide wheel 300 can be set according to actual conditions. The guide wheel 300 can be made of metal such as iron or plastic. The guide wheel 300 is mounted via a pivot. In this embodiment, the guide wheel 300 is rotatably mounted on the fixing component 110 via a pivot. Specifically, the second mounting plate 142 is L-shaped when viewed in the first direction. The second mounting plate 142 can be mounted in a way that fits against the wall of the cabinet. The guide wheel 300 is mounted on the second mounting plate 142 and can rotate around the pivot. Moreover, the guide wheel 300 is located on the side of the fixing component 110 that is away from the other fixing component 110 in the vertical direction.

[0043] Of course, it is not excluded that in other embodiments, the guide wheel 300 is mounted on the cabinet by a bracket, that is, the guide wheel 300 and the slide rail body are set separately.

[0044] In some embodiments, when the guide wheel 300 is provided, a limiting wheel may be added. The central axis of the limiting wheel extends in the vertical direction, and the limiting wheel is positioned close to the first mounting plate 141 relative to the guide wheel 300. There is at least one limiting wheel, and they are arranged at intervals along the first direction. When the cabinet door moves along the first direction, the outer peripheral surface of the guide wheel 300 contacts the surface of the cabinet door, and simultaneously, the outer peripheral surface of the limiting wheel also contacts the surface of the cabinet door. This enhances the guiding effect on the cabinet door and improves the stability of the cabinet door's movement.

[0045] In the rotary door slide rail provided in this embodiment of the utility model, since the two slide rail bodies are symmetrically arranged along the vertical direction, and are fixedly connected to the upper and lower parts of the cabinet door respectively by hinges 200 of the two slide rail bodies, the cabinet door can be stably rotated under the action of the hinges 200, thereby realizing the opening or closing of the cabinet door. Furthermore, when the cabinet door is rotated open, it can move linearly along the first direction following the two sliding components 130 under the action of a pushing force, so that the cabinet door can be hidden and stored on one side of the cabinet body along the second direction. When it is necessary to close the cabinet door, a certain pulling action is applied to the cabinet door to extend it, so that the cabinet door can be rotated and closed subsequently.

[0046] Furthermore, a guide wheel 300 is added to the main body of the slide rail, allowing the guide wheel 300 to work in conjunction with the slide rail main body. This ensures that the rolling trajectory of the guide wheel 300 is tangent to the rotation trajectory of the cabinet door when the slide rail main body is in the extended state. When the cabinet door rotates 90° to the open state, the outer circumferential surface of the guide wheel 300 contacts the surface of the cabinet door, thereby positioning the cabinet door and ensuring that the surface of the cabinet door with the handle is parallel to the first direction. This effectively avoids excessive rotation of the cabinet door, which would make it difficult to push the cabinet door in a straight line.

[0047] Next, people only need to push the cabinet door backward relative to the cabinet body to make the cabinet door move smoothly in a straight line without any horizontal swinging.

[0048] Then, as the cabinet door moves back and forth with the sliding assembly 130, the outer circumferential surface of the guide wheel 300 always rolls in contact with the handle surface of the cabinet door, so that the cabinet door can move stably along the first direction under the good guidance of the guide wheel 300, effectively preventing the cabinet door from swinging in the second direction when moving along the first direction, thereby improving the smoothness of the sliding of the cabinet door during the extension and retraction process and improving people's user satisfaction.

[0049] In this embodiment, the revolving door slide rail uses the upper and lower guide wheels 300 to provide both motion guidance and swing angle limitation for the cabinet door. This prevents the cabinet door from swaying during movement in the first direction, which could easily damage the cabinet door and the slide rail body, making the revolving door slide rail more durable. Moreover, during the rotation of the cabinet door, with the upper and lower guide wheels 300 as the fulcrum, the cabinet door can easily rotate 90° under the drive of the hinge 200 to achieve the closing or opening of the cabinet door.

[0050] In some embodiments, such as Figures 1 to 4 As shown, each slide rail body also includes a first roller 151, a second roller 152, and a wire rope 600.

[0051] The fixing component 110 has a first roller 151 and a second roller 152 at opposite ends along a first direction, which are spaced apart along the first direction. The central axis of the first roller 151 and the central axis of the second roller 152 both extend along a second direction. It is understood that the first roller 151 and the second roller 152 can be of the same size and material. The first roller 151 and the second roller 152 can be made of metal or plastic. Both the first roller 151 and the second roller 152 are rotatably mounted on the fixing component 110 via a pivot. Of course, in other embodiments, it is possible that the first roller 151 and the second roller 152 are fixed relative to the fixing component 110.

[0052] Each wire rope 600 is fixedly connected to two sliding components 130 at both ends, and each wire rope 600 is wound around a first roller 151 and a second roller 152 arranged at intervals in the vertical direction.

[0053] In a specific embodiment, such as Figures 1 to 3As shown, a first roller 151 is mounted on a first mounting plate 141 and is rotatable relative to the first mounting plate 141 about its central axis. A second roller 152 is mounted on a second mounting plate 142 and is rotatable relative to the second mounting plate 142 about its central axis. The second roller 152 and the guide wheel 300 are both located on the same side of the fixing assembly 110 along the first direction.

[0054] like Figure 1 and Figure 2 As shown, for the upper slide rail body, one end of the wire rope 600 is fixedly connected to the sliding seat of the upper sliding assembly 130. The wire rope 600 passes sequentially over the first roller 151 on the upper side and the second roller 152 on the lower side. The other end of the wire rope 600 is fixedly connected to the sliding seat of the lower sliding assembly 130. Here, this wire rope 600 is designated as the first rope body. For the lower slide rail body, one end of the wire rope 600 is fixedly connected to the sliding seat of the lower sliding assembly 130. The wire rope 600 passes sequentially over the first roller 151 on the lower side and the second roller 152 on the upper side. The other end of the wire rope 600 is fixedly connected to the sliding seat of the upper sliding assembly 130. Here, this wire rope 600 is designated as the second rope body. Therefore, viewed along the second direction, the two wire ropes 600 intersect each other.

[0055] Understandably, when the upper sliding component 130 moves from back to front, it applies tension to one end of the first rope, causing the other end of the first rope to pass over the upper first roller 151 and the lower second roller 152, and applies tension to the lower sliding component 130, causing it to move from back to front. Simultaneously, the lower sliding component 130 applies tension to one end of the second rope, causing the other end of the second rope to pass over the lower first roller 151 and the lower second roller 152, and applies tension to the upper sliding component 130.

[0056] Therefore, by adopting such a structural design, it is possible to ensure that the two sliding components 130 arranged vertically move synchronously in the same direction, thereby overcoming the problem of misalignment of the cabinet door and improving the smoothness of the cabinet door's movement.

[0057] Furthermore, the outer surface of the wire rope 600 is coated with an adhesive layer. Understandably, coating the wire rope 600 with adhesive can enhance its wear resistance and prevent it from breaking easily during repeated pulling.

[0058] Furthermore, such as Figures 1 to 3 As shown, each slide rail body also includes an adjustment component.

[0059] The adjusting assembly includes an adjusting screw 162 and a sleeve 161. One end of the wire rope 600 is fixedly connected to one end of the sleeve 161. The other end of the sleeve 161 has a connecting hole, the central axis of which extends along a first direction. The sleeve 161 is slidably connected to the sliding assembly 130 along the first direction. Specifically, the sliding seat of the sliding assembly 130 has a non-circular guide hole, which can be a square hole, a hexagonal hole, etc. The sleeve 161 passes through the guide hole and slides in contact with the inner circumferential surface of the guide hole, allowing the sleeve 161 to move relative to the sliding assembly 130 along the first direction, but preventing it from rotating. The sliding assembly 130 has a through hole, the central axis of which extends along the first direction. The adjusting screw 162 passes through the through hole and can rotate relative to the sliding assembly 130. The adjusting screw 162 is threadedly connected to the connecting hole of the sleeve 161.

[0060] When the adjusting screw 162 is turned clockwise, it is screwed into the connecting hole of the sleeve 161. At this time, the sleeve 161 moves closer to the adjusting screw 162 in the first direction, thus tightening the wire rope 600. When the adjusting screw 162 is turned counterclockwise, it is screwed out of the connecting hole of the sleeve 161. At this time, the sleeve 161 moves away from the adjusting screw 162 in the first direction, thus slackening the wire rope 600.

[0061] In some embodiments, such as Figures 1 to 4 As shown, each slide rail body also includes a locking component.

[0062] The locking assembly includes a limiting protrusion 400 and an elastic wheel 500. One of the limiting protrusion 400 and the elastic wheel 500 is located on the fixed assembly 110, and the other is located on the sliding assembly 130. The central axis of the elastic wheel 500 extends along a second direction, and the elastic wheel 500 is configured to abut against and pass over the limiting protrusion 400. When the slide rail body is in the extended state, the limiting protrusion 400 is located on the side of the elastic wheel 500 away from the hinge 200 along the first direction, and the limiting protrusion 400 is configured to engage and lock the elastic wheel 500.

[0063] Understandably, the elastic wheel 500 can be made of plastic with elastic deformation. The elastic wheel 500 can be fixed or rotatable. The limiting protrusion 400 can be made of metal or plastic. The shape of the limiting protrusion 400 is not limited; viewed along the second direction, it can be an isosceles trapezoid, square, triangular, or other shapes. When the elastic wheel 500 contacts the limiting protrusion 400, and the elastic wheel 500 passes over the limiting protrusion 400 under the action of an external force, the elastic wheel 500 will undergo a certain elastic deformation due to the force of the limiting protrusion 400, allowing the elastic wheel 500 to pass smoothly over the limiting protrusion 400.

[0064] In this embodiment, the limiting protrusion 400 is arc-shaped when viewed along the second direction. The limiting protrusion 400 is disposed on the fixing component 110. Specifically, the limiting protrusion 400 can be integrally formed with the outer rail of the fixing component 110. The limiting protrusion 400 is located on the side of the fixing component 110 near the guide wheel 300 along the first direction. The elastic wheel 500 is disposed on the sliding seat of the sliding component 130.

[0065] As the sliding assembly 130 moves from back to front with the elastic wheel 500, the elastic wheel 500 can pass over the limiting protrusion 400. When the sliding assembly 130 moves forward into position, the elastic wheel 500 will contact the limiting protrusion 400. At this time, the limiting protrusion 400 will lock the elastic wheel 500, preventing the elastic wheel 500 from passing over the limiting protrusion 400 without external force. This allows the sliding assembly 130 to be locked in the extended state, fixing the position of the sliding assembly 130 and the cabinet door, effectively preventing the sliding assembly 130 from driving the cabinet door backward. This solves the problem of the sliding assembly 130 easily shifting after being pulled out in the prior art.

[0066] After the cabinet door is rotated and opened, people can apply a certain pushing force to the cabinet door, causing the sliding component 130 to drive the cabinet door to move backward. During this process, the elastic wheel 500 can pass over the limiting protrusion 400 to release the locking effect between the elastic wheel 500 and the limiting protrusion 400, allowing the cabinet door to move backward into place, thereby achieving the purpose of hiding and retracting the cabinet door.

[0067] Of course, it is not excluded that in other embodiments, a limiting protrusion 400 is provided on the side of the outer rail of the fixed component 110 away from the guide wheel 300 along the first direction. When the sliding component 130 drives the cabinet door to move backward into place, the limiting protrusion 400 can lock the elastic wheel 500, so that the sliding component 130 and the cabinet door remain stationary without external force.

[0068] In some embodiments, such as Figures 1 to 3As shown, the fixing component 110 has a buffer 111 and a rubber wheel 112 at opposite ends along the first direction. The central axis of the rubber wheel 112 extends in the vertical direction. The rubber wheel 112 and the guide wheel 300 are both located on the same side of the fixing component 110 along the first direction. Moreover, the rubber wheel 112 and the guide wheel 300 are arranged at certain intervals along the second direction, so that the rubber wheel 112 and the guide wheel 300 together define a guide channel for the cabinet door to pass through. When the cabinet door passes through the guide channel, the guide wheel 300 rolls into contact with the handle surface of the cabinet door, while the rubber wheel 112 rolls into contact with the opposite surface of the cabinet door. The rubber wheel 112 prevents contact friction between the surface of the cabinet door and the fixing component 110, thus preventing damage to the surface of the cabinet door.

[0069] The buffer 111 is configured to cushion the sliding assembly 130. This design reduces noise generated when the sliding assembly 130 directly impacts the fixed assembly 110 when people push the cabinet door backward.

[0070] In this embodiment, the outer rail of the fixing assembly 110 is provided with a buffer 111 and a rubber wheel 112. The buffer 111 is located at the rear end of the groove, and the rubber wheel 112 is located at the front end of the groove. The shape of the buffer 111 is not limited, and the buffer 111 is a hollow rubber component. The rubber wheel 112 can be mounted on the fixing assembly 110 via a pivot, and the rubber wheel 112 is located in front of the guide wheel 300.
