Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, the utility model provides a sitting posture correction frame, which comprises a clamping mechanism, a telescopic component and a blocking piece 1 connected to the telescopic component.

The telescopic assembly comprises a sleeve 2 and a telescopic piece 3 inserted into the cylindrical inner side of the sleeve 2, the blocking piece 1 is arranged at the upper end part of the sleeve 2, a locking piece used for locking the telescopic piece 3 is further arranged on the sleeve 2, the telescopic piece 3 can move in the sleeve 2, and the telescopic assembly and the locking piece can be locked and limited.

In this embodiment, the locking member includes a reset button 4 and a locking block 5, and a plurality of locking grooves 6 are disposed on the telescopic member 3 and are matched with the locking block 5.

As shown in fig. 5 and 6, the inner side wall of the locking groove 6 is provided with a first upper plane 61 and a first wedge surface 62, and the outer side wall of the locking block 5 is provided with a second upper plane 51 and a second wedge surface 52.

The fixture blocks 5 are arranged in parallel. In the present embodiment, the three latch blocks 5 are arranged in the transverse direction, and the middle portions of the two latch blocks 5 located at the uppermost and the lowermost positions are respectively provided with a notch portion 53.

The reset button 4 is mounted on the sleeve 2 through a rotating shaft 41, and an elastic component acts on the reset button 4 to make it have a reset tendency after being pressed and rotated, in this embodiment, the elastic component is a reset spring 42.

Fixture includes first holder 7 and second holder 8, extensible member 3 pass in proper order an outer sleeve 9 and connect after the through-hole on the first holder 7 in second holder 8, outer sleeve 9 with extensible member 3 screw-thread fit.

The inner lower part of the outer sleeve 9 is provided with an internal thread 91 matched with the external thread 31 of the telescopic piece 3, and the lower end of the sleeve 2 can be inserted into the inner upper part of the outer sleeve 9. The purpose of this structure lies in, can make sleeve pipe 2 and outer sleeve 9 closely cooperate each other, when moving sleeve pipe 2 upwards, can make the lower extreme of sleeve pipe 2 keep in outer sleeve 9 as far as possible, avoids appearing too big gap between the two to influence overall stability, also pleasing to the eye.

Be provided with the groove 32 of stepping down of vertical extension on the lateral wall of extensible member 3, draw-in groove 6 set up in the groove 32 of stepping down. Since the extensible member 3 and the second clamping member 8 are integrally arranged, the outer sleeve 9 needs to be sleeved on the extensible member 3 from the upper part to the lower part, and therefore, the receding groove 32 is arranged, and the clamping groove 6 is arranged in the receding groove 32, so that the outer sleeve 9 is not hindered. In this embodiment, the cross section of the relief groove 32 is arcuate, that is, a part of the arcuate shape is removed from the circular cross section of the telescopic member 3. Of course, in other embodiments, the relief groove 32 may be a concave groove recessed inward.

A vertically extending slot 33 is arranged on the side wall of the telescopic part 3, and a vertical rib 21 for inserting into the slot 33 is arranged on the inner side wall of the sleeve 2. When the sleeve 2 is sleeved on the telescopic part 3, the vertical ribs 21 can be inserted into the slots 33, so that the two are assembled and aligned compactly, the two are prevented from rotating mutually, and the effect of matching keys with key grooves is achieved. In addition, the vertical rib 21 includes a straight plate portion and a wing portion 212 disposed on the straight plate portion 211, and in the embodiment, the cross section of the vertical rib 21 is T-shaped, so that the vertical rib and the wing portion can be prevented from rotating with each other and further from shaking with each other.

By adopting the technical scheme, the simple sitting posture correction frame of the utility model can lock the telescopic part 3 through the locking part, and the outer sleeve 9 is screwed to move downwards relative to the telescopic part 3, so that the first clamping part 7 is pressed, and the first clamping part 7 and the second clamping part 8 can be clamped on the table plate to fix the sitting posture correction frame; when the width between the first clamping member 7 and the second clamping member 8 needs to be adjusted, the position of the outer sleeve 9 on the telescopic member 3 can be adjusted.
