It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] Example 1:

[0039] like Figure 1-8 As shown, this embodiment provides an adjustment structure installed between the seat cushion 20 and the armrest 10 of a seat for adjusting the angle between the seat cushion 20 and the armrest 10. The adjustment structure includes a mounting base 1 and a limiting protrusion 2. The mounting base 1 includes a mounting plate 11 and a connecting plate 12 disposed on the mounting plate 11. The mounting plate 11 is connected to the seat cushion 20. The connecting rod 110 of the armrest 10 is rotatably connected to the connecting plate 12, and the connecting rod 11 can slide along the axial direction of the connecting plate 12. The limiting protrusion 2 is disposed on the connecting rod 110. The connecting plate 12 is provided with a plurality of limiting grooves 121, and the limiting protrusion 2 can be selectively engaged in one of the limiting grooves 121.

[0040] In this embodiment, the adjustment structure is installed between the seat cushion 20 and the armrest 10, connecting the seat cushion 20 and the armrest 10. Specifically, the mounting plate 11 is connected to the seat cushion 20, and the mounting plate 11 is fixedly connected to the bottom of the seat cushion 20 by multiple screws to ensure a firm connection between the mounting plate 11 and the seat cushion 20. Since the connecting rod 110 of the armrest 10 is rotatably connected to the connecting plate 12, and the connecting rod 110 can slide along the axial direction of the connecting plate 12, the limiting protrusion 2 is provided on the connecting rod 110. When the limiting protrusion 2 is engaged in one of the limiting grooves 121, the armrest 10 and the seat cushion are connected. The armrest 10 and seat 20 cannot rotate, ensuring a secure connection. When the angle of the armrest 10 needs adjustment, first move the connecting rod 110 axially to disengage the limiting protrusion 2 from the limiting groove 121. The limiting protrusion 2 releases its restriction on the connecting rod 110, allowing rotation between the connecting plate 12 and the connecting rod 110. Then, rotate the armrest 10 to the desired angle and move the connecting rod 110 axially again, causing the limiting protrusion 2 to re-engage in the corresponding limiting groove 121. The limiting protrusion 2 then restricts the connecting rod 110, completing the angle adjustment of the armrest 10. This adjustment structure, by selectively engaging one of the limiting protrusions 2 in one of the limiting grooves 121 on the connecting plate 12, achieves the angle adjustment of the armrest 10, greatly facilitating user adjustment of the armrest 10 angle according to actual conditions and improving user comfort.

[0041] like Figure 6 and 8 As shown, the connecting plate 12 is provided with a rotating hole 123, and the connecting rod 110 is rotatably connected to the rotating hole 123.

[0042] In this embodiment, the connecting plate 12 is provided with a rotating hole 123. The size of the rotating hole 123 is adapted to the connecting rod 110 so that the connecting rod 110 can rotate in the rotating hole 123 and the connecting rod 110 can move along the axial direction of the connecting plate 12 through the rotating hole 123 so that the limiting protrusion 2 can be engaged in different limiting grooves 121 on the connecting plate 12, thereby realizing the angle adjustment of the handrail 10.

[0043] like Figure 6 and 8 As shown, several limiting grooves 121 are disposed on the inner side of the rotating hole 123, and the limiting protrusion 2 can be selectively engaged in one of the limiting grooves 121.

[0044] In this embodiment, several limiting grooves 121 are provided inside the rotating hole 123. When it is necessary to adjust the angle of the handrail 10, the connecting rod 110 first moves the connecting plate 12 axially, the limiting protrusion 2 exits the limiting groove 121 inside the rotating hole 123, the connecting rod 110 is rotated, the handrail 10 is rotated to the required angle, the connecting rod 110 then moves back along the connecting plate 12 axially, the limiting protrusion 2 is re-engaged into the handrail 10, and the angle of the handrail 10 is adjusted.

[0045] like Figure 3 As shown, the connecting rod 110 is provided with a slot 120, and the limiting protrusion 2 is inserted into the slot 120.

[0046] In this embodiment, the limiting protrusion 2 is inserted into the slot 120, thereby achieving the connection between the limiting protrusion 2 and the connecting rod 110. As one embodiment, the limiting protrusion 2 can also be fixed to the connecting rod 110 by other connection methods, such as bolt connection, which is not limited here.

[0047] like Figure 3-5 As shown, the adjustment structure further includes a limiting component 3, which includes a spring 31 and a limiting block 32; a limiting plate 13 is provided on the mounting plate 11, and the connecting rod 110 is rotatably connected to the limiting plate 13; the limiting block 32 is fixedly connected to the connecting rod 110; the spring 31 is sleeved on the connecting rod 110, and one end of the spring 31 is fixedly connected to the limiting block 32, and the other end of the spring 31 is fixedly connected to the limiting plate 13.

[0048] In this embodiment, a limiting plate 13 is provided on the mounting plate 11, the connecting rod 110 is rotatably connected to the limiting plate 13, the limiting block 32 is fixedly connected to the connecting rod 110, and the spring 31 is sleeved on the connecting rod 110. One end of the spring 31 is fixedly connected to the limiting block 32, and the other end of the spring 31 is fixedly connected to the limiting plate 13. When it is necessary to adjust the angle of the handrail 10, the connecting rod 110 is moved along the connecting plate 12 toward the limiting block 32. The spring 31 is compressed and has elasticity under the action of the limiting plate 13. At this time, the handrail 10 is rotated to adjust the handrail 10 to the required angle. Under the elastic force of the spring 31 of the connecting rod 110, it automatically moves along the connecting plate 12 toward the limiting protrusion 2, and the limiting protrusion 2 re-engages into the limiting groove 121, thus realizing the angle adjustment of the armrest 10. Furthermore, the two ends of the spring 31 are fixedly connected to the limiting block 32 and the limiting plate 13, respectively. When the angle of the armrest 10 does not need to be adjusted, the spring 31 can pull the limiting plate 13, which restricts the connecting plate 12 and prevents the connecting rod 110 from moving axially along the connecting plate 12, thereby preventing the limiting protrusion 2 from exiting the limiting groove 121 and ensuring the connection and fixation between the armrest 10 and the seat cushion 20.

[0049] like Figure 6 As shown, the connecting plate 12 and the limiting plate 13 are disposed opposite to each other on the mounting plate 11.

[0050] In this embodiment, the connecting plate 12 and the limiting plate 13 are disposed opposite to each other on the mounting plate 11, and are connected to the handrail 10 through the two support points of the connecting plate 12 and the limiting plate 13, which further ensures the stability of the handrail 10.

[0051] like Figure 6 and 7 As shown, the mounting plate 11 is provided with a groove 111, which is arranged along the length direction of the mounting plate 11.

[0052] In this embodiment, the mounting plate 11 is provided with a groove 111, which is arranged along the length of the mounting plate 11. The groove 111 plays a reinforcing role and ensures the structural strength of the mounting plate 11.

[0053] like Figure 3 , 6 As shown in Figures 7 and 8, the mounting plate 11 is provided with a first connecting groove 112 and a second connecting groove 113. The first connecting groove 112 and the second connecting groove 113 are respectively located on both sides of the groove portion 111. A first insert block 122 is provided at the bottom of the connecting plate 12, and a second insert block 131 is provided at the bottom of the limiting plate 13. The first insert block 122 is inserted into the first connecting groove 112, and the second insert block 131 is inserted into the second connecting groove 113.

[0054] like Figure 3 As shown, the limiting component 3 also includes a limiting bolt 33, which is fixedly connected to the connecting rod 110, and the limiting bolt 33 is located on the side of the limiting block 32 away from the spring 31.

[0055] In this embodiment, the limiting bolt 33 is fixed to the side of the limiting block 32 away from the spring 31, which further fixes the limiting block 32 and ensures that the limiting block 32 is connected and fixed on the connecting rod 110.

[0056] Example 2:

[0057] This embodiment improves a type of seat. Figure 1-3 The diagram shows a schematic of the armrest 10 and seat cushion 20 connected by an adjustment structure on one side. It can be understood that both armrests 10 are connected to the seat cushion 20 via the adjustment structure to allow for angle adjustment of the armrests 10 on both sides of the seat cushion 20. The seat includes armrests 10, a seat body (not shown in the figure), and the adjustment structure described in Embodiment 1; the seat body includes a seat cushion 20; the armrests 10 and the seat cushion 20 are connected via the adjustment structure.

[0058] In this embodiment, the seat uses the adjustment structure of Embodiment 1 to adjust the angle of the armrest 10, which greatly facilitates the user to adjust the angle of the armrest 10 according to the actual situation, thereby adjusting the space between the seat cushion 20 and the armrest 10 and improving the user's riding comfort.

[0059] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0060] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0061] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0062] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
