Description

TECHNICAL FIELD

[0001] The application relates to the technical field of desks and chairs, in particular to a sit-stand-lie multifunctional split desk and chair. BACKGROUND

[0002] The split desk and chair refers to a design in which the desk and the chair are independently separated and not connected together as a whole. This design is usually applicable to schools, training institutions or other educational places, aiming to provide students with more flexible and comfortable use experience.

[0003] The currently used desk is provided with a support plate at the bottom rear, which is used for supporting the legs when the student lies down. However, in actual use, after the support plate is rotated to the supporting position, since there is lack of fixing or comprehensive supporting force, when the legs are placed thereon, only the vicinity of the rotating shaft can provide support, and other parts basically have no force. In this way, the force point of the legs is too small, and discomfort is caused. CONTENT OF THE UTILITY MODEL

[0007] Preferably, the lower end of the spring is fixedly connected to a sliding plate, and the sliding plate is slidingly connected to the support frame.

[0008] Preferably, a fixing groove is formed in one side of the support column, a first elastic sheet is fixedly connected in the fixing groove, one side of the first elastic sheet is fixedly connected to a clamping block, and the clamping block is clamped to the support frame.

[0009] Preferably, a clamping groove is formed in one side wall of the support frame, and the clamping groove is clamped to the clamping block.

[0010] Preferably, a pushing block is slidingly connected in the clamping groove, one side of the pushing block is fixedly connected to a pushing plate, and one side of the pushing plate is fixedly connected to a second elastic sheet.

[0011] Preferably, a fixing frame is mounted on one side of the support plate, the fixing frame is composed of two front and rear fixing plates and a rotating rod, and the rotating rod is fixedly connected to the front and rear fixing plates.

[0012] Preferably, the rotating rod of the fixing frame is rotatably connected with a mounting ring, and one side of the mounting ring is fixedly connected with a supporting plate.

[0013] In summary, the present application has the following beneficial technical effects:

[0014] In the utility model, through optimizing the supporting structure, the problem of insufficient supporting area of the traditional supporting plate and concentrated stress points leading to discomfort of legs is effectively solved. Students push the push plates on both sides to move the push block and extrude the clamping block, so that the supporting frame and the supporting column are disengaged from clamping, and the spring is immediately stretched and reset to drive the supporting frame and the auxiliary plate to rise. Then, the mounting ring is rotated to make the back of the supporting plate contact with the auxiliary plate to form a supporting structure. The students place the legs on the supporting plate, and the supporting plate slightly rotates under pressure to extrude the auxiliary plate to descend, and the spring lifts the auxiliary plate to push the other end of the supporting plate to adhere to the legs, so that the supporting area of the legs is expanded. Through dynamic adjustment, the leg pressure is evenly distributed, the supporting stability is enhanced, the discomfort caused by single-point stress is reduced, the comfort is improved, the operation is convenient, and the ergonomic demand is met.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings Figures 1-4 The application is further described in detail.

[0021] The application embodiment discloses a sitting-lying multifunctional split desk and chair. Figures 1-4The utility model provides a kind of sit-stand-lie multifunctional split desk and chair, including and chair 2 matched desk 1, desk 1 lower end front and rear part fixedly connected support frame 3, support frame 3 lower end fixedly connected support plate 4, support plate 4 one side is equipped with supporting plate 7, support plate 4 upper end front and rear part fixedly connected support column 8, support column 8 upper end fixedly connected slide plate 84, spring 81 is fixedly connected on slide plate 84 upper end, spring 81 upper end fixedly connected support frame 9 inner wall, when support frame 9 and support column 8 are clamped, spring 81 is in compression state, support frame 9 upper end fixedly connected auxiliary plate 10, auxiliary plate 10 is lifted by spring 81 can rise, and lift after rotating supporting plate 7, to make supporting plate 7 end also can be forced to support student leg, reduce discomfort.

[0022] By dynamic adjustment, the leg pressure is evenly distributed, the support stability is enhanced, the discomfort caused by single-point force is reduced, the comfort is improved, the operation is convenient, and the ergonomic demand is met.

[0023] By adopting the above technical scheme, the support column 8 is provided with a fixing groove on one side, and a first elastic sheet 82 is fixedly connected in the fixing groove. The first elastic sheet 82 is fixedly connected with a clamping block 83 on one side. The clamping block 83 is clamped with the support frame 9. A clamping groove is formed in one side wall of the support frame 9, and the clamping block 83 is clamped in the clamping groove. A push block 91 is slidably connected in the clamping groove. The push block 91 is fixedly connected with a push plate 92 on one side. The push plate 92 is fixedly connected with a second elastic sheet 93 on one side.

[0024] By adopting the above technical scheme, the support plate 4 is provided with a fixing frame 5 on one side. The fixing frame 5 is composed of two front and rear fixing plates and a rotating rod. The rotating rod is fixedly connected with the fixing plates on front and rear parts. The fixing plates are fixedly connected with the support plate 4 at lower ends. The rotating rod of the fixing frame 5 is rotatably connected with a mounting ring 6. The mounting ring 6 is fixedly connected with the supporting plate 7 on one side. The mounting ring 6 can be rotatably installed. The mounting ring 6 drives the supporting plate 7 to rotate, so as to adjust the position of the supporting plate 7.

[0025] The implementation principle of the embodiment of the sit-stand-lie multifunctional split desk and chair is as follows: the student can push the push plate 92 on both sides with legs or feet, so that the push plate 92 drives the push block 91 to move and simultaneously extrudes the second elastic sheet 93 to contract. The movement of the push block 91 extrudes the clamping block 83 clamped in the clamping groove, so that the clamping block 83 is separated from the clamping groove after being extruded. At this time, the support frame 9 is no longer clamped with the support column 8, so that the spring 81 at the upper end of the slide plate 84 is stretched and restored, the spring 81 drives the support frame 9 to rise, and drives the auxiliary plate 10 to rise. Then, the mounting ring 6 on one side is rotated, the mounting ring 6 drives the supporting plate 7 to rotate, and the back of the supporting plate 7 is in contact with the auxiliary plate 10, as shown in FIG. 6B. Figure 2As shown, at this time the supporting plate 7 is lifted by the auxiliary plate 10, then the student places both legs on the supporting plate 7, after the leg is placed, the supporting plate 7 is slightly rotated and pressed by the auxiliary plate 10 to descend, but is lifted by the spring 81, so that the auxiliary plate 10 pushes one end of the supporting plate 7 to contact the leg of the student, thereby increasing the stress area of the support and reducing the discomfort.

[0026] When not in use, only need to rotate the mounting ring 6, so that the mounting ring 6 drives the supporting plate 7 to restore to the position shown in the figure, then press the auxiliary plate 10, so that the supporting frame 9 descends and presses the spring 81 to shrink, the supporting frame 9 descends until the clamping groove is aligned with the clamping block 83, and the one-way elastic sheet 82 on one side of the clamping block 83 pushes the clamping block 83 into the clamping groove to be clamped, so that the supporting frame 9 is clamped with the supporting column 8.
