Abstract
The invention discloses a leg sliding locking mechanism which comprises a leg supporting frame, a sliding rod, a connecting piece and a locking device, wherein both the leg supporting frame and the sliding rod are hinged with the connecting piece; the locking device is arranged on the leg supporting frame; the locking device comprises a locking hole; the sliding rod is sleeved by the locking hole; and the sliding rod is arranged below the leg supporting frame and is used for supporting the leg supporting frame. When the sliding rod needs to be rotated, the locking hole is kept to be parallel with the sliding rod since external force is exerted on the locking hole, so that the sliding rod can move in the locking hole when rotated; the leg supporting frame also rotates relative to the connecting piece when the sliding rod is rotated; and the locking hole is not parallel with the sliding rod when the external force is removed after the leg supporting frame is rotated by a required angle, so that the sliding rod is locked by virtue of the locking hole. The leg sliding locking mechanism disclosed by the invention can lock the sliding rod by virtue of the locking hole, and the locking mechanism is simple in structure; and the sliding rod can be used for effectively supporting the leg supporting frame without the assistance of atmospheric pressure or hydraulic pressure, so that the locking mechanism is convenient in mounting, and production and material costs are reduced.

According to an aspect of the present invention, provide a kind of leg to slide tight latch mechanism, comprise thigh support frame, sliding bar, connector and locking device, thigh support frame and sliding bar are all hinged with connector, locking device is located on thigh support frame, and locking device comprises locking hole, and sliding bar is set in locking hole, sliding bar is positioned at the below of thigh support frame, for leg-supporting bracing frame.
The invention has the beneficial effects as follows: be provided with sliding bar and locking hole, when sliding bar needs to rotate, External Force Acting, on locking hole, makes locking hole parallel with sliding bar, can move when ensureing that sliding bar rotates in locking hole; When sliding bar rotates, thigh support frame also opposite joints rotates; After thigh support frame turns to required angle, cancel external force, locking hole and sliding bar not parallel, locking hole is locked sliding bar, prevents sliding bar from moving, ensure sliding bar can leg-supporting bracing frame.Leg of the present invention slides tight latch mechanism by the locking of locking hole realization to sliding bar, and structure is simple, without the need to adopting air pressure or hydraulic pressure support, easy for installation, reduces production and material cost.
In some embodiments, locking hole can comprise the first hole and the second hole, and the first hole is connected with the second hole, and the internal diameter in the first hole is less than the internal diameter in the second hole, and the first hole is positioned at the hinged end close to sliding bar and connector.Thus, by the aperture difference between the first hole and the second hole, both can be made to form certain gradient, and then make sliding bar after stopping operating, sliding bar can be locked by this gradient.
In some embodiments, locking device can also comprise movable part, and the first hole and the second hole are all located on movable part, movable part and thigh support frame hinged.Thus, be provided with movable part, offering of the first hole and the second hole can be facilitated, and facilitate External Force Acting on movable part, conveniently can regulate the angle of locking hole.
In some embodiments, the upper surface in the first hole is mutually concordant with the upper surface in the second hole, makes the lower surface in the first hole and the second junction, hole form brace table.Thus, can be clamped sliding bar by brace table.
In some embodiments, the external diameter of sliding bar is less than the internal diameter in the first hole.Thus, sliding bar can be facilitated to move in the first hole.
In some embodiments, the leg tight latch mechanism that slides can also comprise leg, and leg is fixed on the downside of thigh support frame, and locking device is located on thigh support frame by leg.Thus, being provided with leg can the installation of portable propelling part.
Accompanying drawing explanation
Fig. 1 is that leg of the present invention slides the structural representation of tight latch mechanism.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
With reference to Fig. 1: leg slides tight latch mechanism, comprise thigh support frame 1, sliding bar 2, connector 3 and locking device 4, thigh support frame 1 and sliding bar 2 are all hinged with connector 3, locking device 4 is located on thigh support frame 1, locking device 4 comprises locking hole 41, sliding bar 2 is set in locking hole 41, and sliding bar 2 is positioned at the below of thigh support frame 1, for leg-supporting bracing frame 1.Wherein, connector 3 is L-shaped, and the two ends of connector 3 are arranged with the first turning cylinder 6 and the second turning cylinder 7 respectively, and one end of thigh support frame 1 is set on the first turning cylinder 6, hinged with connector 3 by the first turning cylinder 6; One end of sliding bar 2 is set on the second turning cylinder 7, hinged with connector 3 by the second turning cylinder 7.Under external force, sliding bar 2 can be rotated by the second turning cylinder 7 opposite joints 3, and thigh support frame 1 can be rotated by the first turning cylinder 6 opposite joints 3.
Locking hole 41 comprises the first hole 411 and the second hole 411, hole 412, first is connected with the second hole 412, and the internal diameter in the first hole 411 is less than the internal diameter in the second hole 412, and the first hole 411 is positioned at close to the hinged end of sliding bar 2 with connector 3.The upper surface in the first hole 411 is mutually concordant with the upper surface in the second hole 412, makes the lower surface in the first hole 411 and the second junction, hole 412 form brace table 43.Conveniently sliding bar 2 is through locking hole 41, and the external diameter of sliding bar 2 is less than the internal diameter in the first hole 411.In actual use, the diameter in the first hole 411 is 12mm, the diameter in the second hole 412 is 16mm, the external diameter of sliding bar 2 is 10mm, sliding bar 2 can be moved in the first hole 411, make sliding bar 2 can rotate within the scope of certain angle simultaneously, meet the angle adjustment scope of thigh support frame 1.
