Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0042] Reference Figures 1 to 3 The first embodiment of the utility model provides a bearing structure, including a main body 100, a movable member 200, a bearing wheel 400 and an adjusting assembly 300, wherein the main body 100 is provided with a mounting groove 110, a first opening 120 and an adjusting hole 140, the first opening 120 and the adjusting hole 140 are both connected to the mounting groove 110, the main body 100 has a first side and a second side opposite to each other in a vertical direction, and the first opening 120 is located on the first side; the movable member 200 is at least partially accommodated in the mounting groove 110; the adjusting assembly 300 includes an adjusting member 310 and a bearing wheel 311; The connecting member 320 and the abutting member 320 are accommodated in the installation groove 110, the adjusting member 310 is passed through the adjusting hole 140, the adjusting member 310 is connected to the abutting member 320, the abutting member 320 abuts against the movable member 200, and the adjusting member 310 can drive the abutting member 320 to move to change the position of the movable member 200 along the vertical direction; the bearing wheel 400 is rotatably connected to the movable member 200, at least part of the bearing wheel 400 is located below the first opening 120, and the bearing wheel 400 can drive the main body 100 to move along the first direction, and the first direction intersects with the vertical direction.

[0043] When adjusting the bearing structure, the adjusting member 310 is connected to the abutment member 320 and can drive the abutment member 320 to move, thereby changing the position of the abutment member 320 abutting against the movable member 200, so that the position of the movable member 200 in the vertical direction changes and the size of the bearing wheel 400 that exceeds the first opening 120 in the vertical direction changes, thereby changing the size of the bearing structure in the vertical direction. For example, after being connected to an object, the bearing structure can be adjusted to a smaller size for assembly, and restored to the use state after assembly is completed, which is convenient for the installation of the bearing structure and the object.

[0044] Reference Figure 2 Specifically, a second opening 130 is further provided on the second side of the main body 100, through which multiple components of the bearing structure can be assembled and subsequently maintained, thereby improving the convenience of use.

[0045] Reference Figure 2 In some embodiments, the adjusting member 310 can drive the abutting member 320 to move along the first direction. Along the first direction, the surfaces facing each other of the abutting member 320 and the main body 100 are respectively the first abutting surface 3221 and the second abutting surface 150. The movable member 200 abuts against the first abutting surface 3221 and the second abutting surface 150 and can slide relative to the first abutting surface 3221 and the second abutting surface 150. From the first side to the second side, the distance between the first abutting surface 3221 and the second abutting surface 150 gradually increases. The surfaces of the movable part 200 on both sides along the first direction are respectively fitted with the first abutting surface 3221 and the second abutting surface 150, and the first abutting surface 3221 and the second abutting surface 150 abut against the movable part 200 at the same time to limit the lowest position of the movable part 200 in the vertical direction. Therefore, when the adjusting part 310 drives the abutting part 320 to move, if the first abutting surface 3221 moves along the first direction away from the second abutting surface 150, the position of the movable part 200 in the vertical direction will decrease, and if the first abutting surface 3221 moves along the first direction toward the second abutting surface 150, the position of the movable part 200 in the vertical direction will increase, thereby synchronously changing the position of the supporting wheel 400 in the vertical direction.

[0046] In some embodiments, the angles of the first abutting surface 3221 and the second abutting surface 150 relative to the horizontal plane are equal and are both 30° to 60°. The angles of the first abutting surface 3221 and the second abutting surface 150 relative to the horizontal plane can be selected to be 30°, 40°, 45°, 50°, 60° or any other value between 30° and 60°. When selecting the angle between the first abutment surface 3221 and the second abutment surface 150 and the horizontal plane, the adjustment size of the movable part 200 in the vertical direction and the resistance encountered by the abutment surface 320 when adjusting the movable part 200 to move should be comprehensively considered. The smaller the angle between the first abutment surface 3221 and the second abutment surface 150 relative to the horizontal plane, the smaller the resistance of the abutment surface 320 when adjusting the movable part 200 to move, but the smaller the adjustable range of the movable part 200 in the vertical direction is; conversely, the larger the angle between the first abutment surface 3221 and the second abutment surface 150 relative to the horizontal plane, the greater the resistance of the abutment surface 320 when adjusting the movable part 200 to move, but the larger the adjustable range of the movable part 200 in the vertical direction is. Therefore, the angle between the first abutment surface 3221 and the second abutment surface 150 and the horizontal plane is selected to be 30° to 60°. While the adjustment resistance is small, there is a large adjustment range, which can meet the use requirements of the bearing structure.

[0047] Reference Figure 2 In some embodiments, the bearing structure further includes a fixing member 500, the adjusting member 310 includes a second connecting portion 311 and an adjusting portion 312, the adjusting portion 312 is passed through the adjusting hole 140 and connected to the main body 100, the abutting member 320 includes a first wall 321 and a second wall 322, the first wall 321 and the second wall 322 are spaced apart along the first direction, the first wall 321 is provided with a connecting hole 3211, the extending direction of the connecting hole 3211 is parallel to the first direction, and the second wall 322 abuts against the first wall 321 on one side thereof. The movable part 200, the second connecting part 311 is passed through the connecting hole 3211, and the fixing part 500 is sleeved on the outer periphery of the second connecting part 311; wherein, the adjusting part 310 can drive the fixing part 500 to abut against the side of the first wall 321 toward the second wall 322, so as to drive the abutting part 320 to move in the direction away from the second abutting surface 150, and / or, the end of the second connecting part 311 away from the adjusting part 312 can abut against the second wall 322, so as to drive the abutting part 320 to move in the direction close to the second abutting surface 150.

[0048] Specifically, the adjustment hole 140 is a threaded hole, and the outer surface of the adjustment part 312 has threads and can cooperate with the adjustment hole 140. When adjusting, the screwing position of the adjustment part 312 and the adjustment hole 140 is changed by rotating the adjustment part 312, thereby driving the abutment 320 to move synchronously, and the adjustment hole 140 can also play a role in fixing the position of the adjustment part 310, ensuring that the adjustment part 310 and the abutment 320 do not move along the first direction when no adjustment is required, so that the position of the movable part 200 along the vertical direction can be determined. In addition, the movable part 200 also includes a third wall 323, the third wall 323 connects the first wall 321 and the second wall 322, and the first wall 321, the second wall 322 and the third wall 323 jointly define a receiving cavity 324, and the fixing part 500 is received in the receiving cavity 324 and can move synchronously with the movement of the adjustment part 310.

[0049] Reference Figure 2 and Figure 3 In some embodiments, the second connecting portion 311 is further provided with a limiting groove 3121, which is annular. The fixing member 500 is accommodated in the limiting groove 3121 and abuts against the bottom wall of the limiting groove 3121. The limiting groove 3121 can limit the position of the fixing member 500 along the first direction, and apply an abutting force to the fixing member 500 when the limiting member 700 abuts against the first wall 321, so that the fixing member 500 can drive the abutting member 320 to move, and the fixing member 500 can be elastically deformed along the radial direction of the connecting hole 3211.

[0050] Specifically, the diameter of the adjustment hole 140 is smaller than the diameter of the fixing member 500. Therefore, when installing the fixing member 500, the fixing member 500 is first installed in the limiting groove 3121, and then the fixing member 500 is compressed along the radial direction of the connecting hole 3211 until it can pass through the connecting hole 3211. Then, the fixing member 500 is moved into the accommodating cavity 324 along the connecting hole 3211. The fixing member 500 restores its original size in the accommodating cavity 324, so that when the adjustment member 310 moves, it can abut against the side of the first wall 321 facing the second wall 322, so as to drive the abutting member 320 to move in a direction away from the second abutting surface 150. Among them, the fixing member 500 can be selected as an open collar.

[0051] Reference Figure 2 and Figure 3In some embodiments, the bearing structure further includes an elastic member 600, which is connected to the main body 100, and the elastic member 600 abuts against a side of the movable member 200 away from the first opening 120, and the elastic member 600 is used to apply a force to the movable member 200 from the second side toward the first side. Since the distance between the first abutting surface 3221 and the second abutting surface 150 gradually increases from the first side to the second side, when the movable part 200 is subjected to an upward force, the first abutting surface 3221 and the second abutting surface 150 have no constraints on the movable part 200, and the elastic part 600 abuts against the side of the movable part 200 away from the first opening 120, so that when the movable part 200 is subjected to force and the force is greater than the elastic force of the elastic part 600, for example, when the ground is uneven or there are foreign objects on the movement trajectory of the load-bearing wheel 400 and the force is applied, the load-bearing wheel 400 and the movable part 200 can move upward as a whole to avoid damage, and after the force disappears, the movable part 200 is re-abutted against the first abutting surface 3221 and the second abutting surface 150 under the action of the elastic part 600 and its own gravity, thereby completing the resetting of the movable part 200 and the load-bearing wheel 400.

[0052] Reference Figure 2 In some embodiments, the elastic member 600 includes a first connection portion 610 and an abutment portion 620, one end of the first connection portion 610 is connected to the main body 100, the other end of the first connection portion 610 extends downwardly obliquely, the abutment portion 620 is connected to one end of the first connection portion 610 away from the main body 100, and the abutment portion 620 abuts against the movable member 200. Specifically, the elastic member 600 is selected as a spring sheet, and during the upward movement of the movable member 200, the first connection portion 610 remains stationary, the abutment portion 620 always keeps in contact with the movable member 200 and moves synchronously with the movable member 200 to undergo elastic deformation, and as the movable member 200 rises, the magnitude of the force applied by the abutment portion 620 to the movable member 200 also increases accordingly.

[0053] Reference Figure 2 and Figure 3 Furthermore, the number of the elastic members 600 is at least two, and the two first connecting portions 610 are respectively connected to the two ends of the main body 100 along the first direction. The contact positions of the abutting portions 620 provided on the two elastic members 600 and the movable member 200 are respectively located on both sides of the center of the movable member 200 along the first direction. When the movable member 200 is subjected to an upward force in the vertical direction, the two elastic members 600 can apply a force to the movable member 200 together, which can provide a large downward force while improving the stability of the movable member 200, and preventing any side of the movable member 200 along the first direction from tilting during the movement.

[0054] Reference Figure 2 and Figure 3In some embodiments, the bearing structure further includes a stopper 700, which is connected to the main body 100. The connection position of the stopper 700 is closer to the second side than the first side, and the stopper 700 is used to abut against the movable member 200 in the vertical direction. The stopper 700 is used to limit the maximum travel of the movable member 200 in the vertical direction. Here, the bearing wheel 400 still partially exceeds the first opening 120, and can maintain the support for the main body 100. At the same time, the limit of the movable member 200 by the stopper 700 can effectively protect the elastic member 600 and prevent the elastic member 600 from plastic deformation.

[0055] Specifically, the limiting member 700 is selected as a screw, and the side wall of the main body 100 is provided with a threaded hole. The limiting member 700 is screwed into the threaded hole and is at least partially accommodated in the mounting groove 110, thereby realizing the limiting effect on the movable member 200 in the vertical direction. The number of the limiting members 700 is at least two and the two limiting members 700 can respectively abut on both sides of the center of the movable member 200 along the first direction, thereby preventing the movable member 200 from tilting or rotating when a force is applied to the movable member 200.

[0056] Reference Figure 2 and Figure 3 In some embodiments, the main body 100 includes a main body portion 101 and a bearing portion 102. The main body portion 101 is provided with a mounting groove 110, a first opening 120 and an adjustment hole 140. The bearing portion 102 is connected to a side of the main body portion 101 away from the mounting groove 110. The bearing portion 102 and the main body portion 101 are used together to bear an object. Specifically, the bearing portion 102 is provided with a through hole extending in a vertical direction, and a threaded fastener can be passed through the through hole and locked to an object, thereby realizing the connection between the object and the second side of the main body 100. In addition, the main body portion 101 and the bearing portion 102 are used together to bear an object, which can increase the contact area with the object, so that the force on the object is more uniform, and the stability of the movement of the bearing structure when bearing the object is increased.

[0057] In some embodiments, to avoid noise during the movement of the load-bearing wheel 400, the surface material of the load-bearing wheel 400 is a polymer wear-resistant material (such as high-strength wear-resistant materials such as POM or nylon), and to ensure that the load-bearing wheel 400 can still rotate smoothly under a large load, the bearing inside the load-bearing wheel 400 is selected as a ball bearing.

[0058] The second embodiment of the utility model provides a door and window device (not shown in the figure), including a frame, doors and windows, and the bearing structure provided by the first embodiment. The doors and windows are installed on the second side of the main body 100, and the doors and windows and the bearing structure are installed in the frame. The door and window device includes the bearing structure provided by the first embodiment, and at least has all the advantages of the bearing structure. When installing, the doors and windows can be connected to the second side of the main body 100 first, and then the doors and windows and the bearing structure can be installed in the frame as a whole. In the process of installing in the frame, by adjusting the height of the bearing structure, the difficulty of installing the doors and windows and the bearing structure can be reduced, and the convenience of installation can be improved.

[0059] Specifically, the door and window device includes a plurality of bearing structures, and the plurality of bearing structures are arranged at intervals along a first direction. The plurality of bearing structures can bear the doors and windows at the same time, so that the overall stability of the door and window device is improved.

[0060] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model.
