Description

Technical Field

[0001] This utility model relates to the field of folding chair technology, specifically to a connecting seat structure for a folding chair. Background Technology

[0002] The connecting seat structure of a folding chair is a key component used to connect and support the various parts of the folding chair, ensuring that the chair can be unfolded and folded smoothly. Different types of connecting seat structure designs are designed to improve the stability of the folding chair's function while reducing manufacturing difficulty and cost.

[0003] The connecting structure of modern folding chairs typically connects the seat plate and back panel at the top and the two legs at the bottom. The chair is then rotated and folded via the connecting seat. While this structure allows for a more stable folding and unfolding of the chair, it also has the disadvantages of making the structure more complex and increasing manufacturing costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example

[0025] Please see Figures 1 to 6 The present invention provides a technical solution: a connecting seat structure for a folding chair, including a seat plate 1, a rotating shaft sleeve 3 fixedly connected to one end of the seat plate 1, a rotating shaft fixedly connected inside the rotating shaft sleeve 3, a sliding shaft 5 fixedly connected to one side of the rotating shaft sleeve 3, a slide rail 501 fixedly connected to the outer surface of the sliding shaft 5, a sliding sleeve 6 slidably connected to the outer surface of the slide rail 501, a mating block 7 fixedly connected to one side of the sliding sleeve 6, a left support leg 8 rotatably connected to the outer surface of the rotating shaft, a support plate 9 rotatably connected to the middle of the left support leg 8, a locking plate rotating shaft 10 rotatably connected to one end of the support plate 9, a locking plate 11 fixedly connected to one end of the locking plate rotating shaft 10, an installation groove 902 opened inside the support plate 9, and an auxiliary support plate 12 rotatably connected inside the installation groove 902.

[0026] Specifically, through the cooperation of the mating block 7 and the mating groove 201, the back panel can be fixed by adjusting the angle of the back panel 2 and pressing the sliding sleeve 6 to make the mating block 7 slide into the mating groove 201. Through the cooperation of the support plate 9 and the locking plate 11, the height of the folding chair can be adjusted by locking the locking plate 11 into the locking groove 101 at different locations.

[0027] Please see Figures 1 to 4 A handle 4 is fixedly connected to the front of the rotating sleeve 3. A back plate 2 is rotatably connected to the outer surface of the rotating sleeve 3. A mating groove 201 is provided on one side of the back plate 2. The sliding shaft 5 is located inside the mating groove 201. The cross-sectional shape and size of the mating groove 201 are the same as those of the mating block 7.

[0028] Specifically, through the cooperation of the mating block 7 and the mating groove 201, during use, the angle of the back plate 2 can be adjusted and the sliding sleeve 6 can be pressed to make the mating block 7 slide into the interior of the mating groove 201, thereby completing the fixation of the back plate. This achieves the purpose of quickly fixing the back plate through the cooperation of the mating block 7 and the mating groove 201, thus achieving the purpose of simple structure and convenient and quick use.

[0029] Please see Figures 5 to 6 One end of the auxiliary support plate 12 is rotatably connected to the auxiliary clamping plate shaft 13, and one side of the auxiliary clamping plate shaft 13 is fixedly connected to the auxiliary clamping plate 14. The size of the auxiliary clamping plate 14 is slightly smaller than the size of the clamping plate 11. The bottom of the seat plate 1 is provided with a number of clamping slots 101, which are evenly distributed in a linear array on the bottom of the seat plate 1. The cross-sectional size of the clamping slots 101 is slightly larger than the cross-sectional size of the clamping plate 11. The spacing between the left support legs 8 is slightly smaller than the width of the seat plate 1. The width of the support plate 9 is slightly smaller than the spacing between the two left support legs 8. The middle of the support plate 9 is fixedly connected to the support plate shaft 901, which is rotatably connected to the middle of the left support leg 8. The auxiliary support plate 12 is rotatably connected to the outer surface of the support plate shaft 901.

[0030] Specifically, through the cooperation of the support plate 9 and the locking plate 11, the locking plate 11 can be locked into the locking slots 101 at different locations during use. This allows the height of the folding chair to be adjusted by adjusting the angle between the support plate 9 and the left support leg 8. This simplifies the connecting seat structure while allowing for the adjustment of the seat plate 1, achieving the goal of simplifying the structure and improving the practicality of the device.

[0031] In use, firstly, the left support leg 8 is rotated via the pivot inside the pivot sleeve 3 to separate the left support leg 8 from the seat plate 1. Then, the support plate 9 is rotated via the pivot 901 so that the retaining plate 11 at one end of the support plate 9 is engaged with the corresponding retaining groove 101 below the seat plate 1 via the retaining plate pivot 10. At the same time, the auxiliary support plate 12 inside the mounting groove 902 is rotated via the pivot 901 so that the auxiliary retaining plate 14 is engaged with the corresponding retaining groove 101 below the seat plate 1 via the auxiliary retaining plate pivot 13. This design allows for adjustment of the seat plate 1's height and also improves the stability of the folding chair through the auxiliary support plate 12. Once the base is fixed, only... To fix the back panel, rotate the back panel 2 to the appropriate angle, then press the sliding sleeve 6 to slide along the slide rail 501 until it is locked into the mating groove 201 on the back panel 2. After use, simply pull out the sliding sleeve 6 and lift the folding chair using the handle 4. The back panel 2 will rotate and fit against the seat panel 1 via the pivot in the pivot sleeve 3. At the same time, the bottom support plate 9 can also rotate via the pivot 901 to overlap with the left support leg 8. After rotation, the left support leg 8 can also fit against the bottom surface of the seat panel 1, thus allowing the folding chair to be fully folded. The structure is simple and the folded size is small, making it easy to carry.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
