DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the embodiments.

[0027] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0028] See also Figure 1 The utility model provides an ankle pressing roller mechanism for an intelligent posture adjustment bed, comprising two pressing roller members 10, the two pressing roller members 10 are connected by a transverse rod 110, and the middle bottom of the transverse rod 110 is installed on an ankle support 30 through a connecting assembly 20;

[0029] The ankle support 30 is provided with two placement grooves 301 , which are used to place the ankles. The two pressing roller members 10 are respectively located directly above the two placement grooves 301 .

[0030] The connecting assembly 20 includes a hollow cylinder 210 and a connecting rod 220;

[0031] Connecting rod 220: The top of the connecting rod 220 is connected to the top of the transverse rod 110, and the bottom end of the connecting rod 220 is arranged in the hollow cylinder 210. A receiving groove 2201 is opened on the side of the bottom end of the connecting rod 220. The two ends of the receiving groove 2201 are respectively sleeved with limiting members 230. An elastic member No. 1 231 is arranged between the two limiting members 230. The side of the limiting members 230 that is away from each other is located outside the receiving groove 2201 under the action of the elastic member No. 1 231. At the same time, the side of the limiting members 230 that is away from each other is partially located outside the receiving groove 2201 due to the obstruction of the through groove 211, and the limiting member 230 cannot be completely separated from the receiving groove 2201.

[0032] Hollow cylinder 210: Four through slots 211 are provided on the side wall of the hollow cylinder 210. The four through slots 211 are rotationally symmetric about the center of the hollow cylinder 210. The width value of the inner slot opening of the through slot 211 in the hollow cylinder 210 is greater than the width value of the outer slot opening of the through slot 211 in the hollow cylinder 210. The width value of the opening of the through slot 211 gradually decreases from inside to outside, which is used to prevent the limiting member 230 from moving out of the storage slot 2201. The top of the inner cavity of the through slot 211 is connected with a limiting spike 212.

[0033] Limiting member 230: On the side of the two limiting members 230 away from each other, there are triangular areas 2301 with upper and lower planes inclined left and right. The width value of the widest part of the triangular area 2301 is greater than the width value of the through slot 211, so that the triangular area 2301 extends out of the through slot 211. Through holes 2302 are provided on the triangular area 2301. The limiting member 230 can be sleeved on the limiting spike 212 through the through hole 2302, and the connecting rod 220 is prevented from rotating by the limiting spike 212.

[0034] A second elastic member 240 is arranged inside the hollow cylinder 210. The top of the second elastic member 240 abuts against the bottom of the connecting rod 220, and a vertically upward force is provided for the connecting rod 220 through the second elastic member 240.

[0035] The bottom of the hollow cylinder 210 can be installed on the push shaft of the electric cylinder. The push shaft of the electric cylinder passes through the ankle support 30, and the pressing force of the pressing roller member 10 is controlled by the electric cylinder.

[0036] Working principle and usage process of the present utility model: Before the user gets on the intelligent body posture adjustment bed, press down the pressing roller member 10, so that the connecting rod 220 moves downward. The connecting rod 220 drives the limiting member 230 to move downward in the through slot 211, so that the limiting member 230 moves out of the limiting spike 212. At the same time, the connecting rod 220 compresses the second elastic member 240. Then rotate the connecting rod 220. Since there are triangular areas 2301 on the side of the two limiting members 230 away from each other, when the inclined surface of the triangular area 2301 is abutted by the side wall of the through slot 211, the two limiting members 230 will be received into the storage slot 2201, and at the same time compress the first elastic member 231. When the connecting rod 220 rotates 90 degrees, at this time the two limiting members 230 are located in the other two through slots 211, and the limiting member 230 extends out of the through slot 211 again under the action of the first elastic member 231. Release the connecting rod 220, and the connecting rod 220 moves upward under the action of the second elastic member 240, so that the through hole 2302 on the limiting member 230 is sleeved on the limiting spike 212 again;

[0037] Since the two pressing roller members 10 change from horizontal to vertical and move away from directly above the placement slot 301, the user can place the ankles without disassembling the roller pressing member 10.

[0038] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
