Improved structure of locking mechanism between vertical tube and adjusting tube for fitness equipment

Abstract

The invention discloses an improved structure of a locking mechanism between a vertical tube and an adjusting tube for fitness equipment. The vertical tube is freely inserted in the adjusting tube, the vertical tube is fixed relative to the position of the adjusting tube through the locking mechanism, and the locking mechanism comprises a spring bolt and a pressing block. The spring bolt elastically stretches out and draws back and is positioned at the side, facing the vertical tube, of the pressing block, a ratchet face is formed on the outer side wall, facing the spring bolt, of the vertical tube in the axial direction of the vertical tube, and the ratchet face is provided with a plurality of tooth notches in the same inclined direction. The end, facing the vertical tube, of the spring bolt can be just separated from and blocked in any tooth notch of the ratchet face. In addition, a pair of long-strip-shaped limiting blocks is detachably and fixedly arranged on the side, facing the vertical tube, of the pressing block, the spring bolt is movably placed between the long-strip-shaped limiting blocks, and the long-strip-shaped limiting blocks can be separated from and pressed on the vertical tube under the effect of the pressing block. Adjustment and positioning of the position between the vertical tube and the adjusting tube can be effectively achieved through matching of the spring bolt and the long-strip-shaped limiting blocks, and the locking mechanism has multiple working gears, and is convenient to operate and diversified.

Description

technical field [0001] The invention relates to the technical field of locking mechanisms, and specifically provides an improved structure of a locking mechanism between a riser for fitness equipment and an adjustment tube. Background technique [0002] At present, the standpipe and adjustment tube used in fitness equipment are mainly used for height adjustment at the handlebars and seat cushions. The common fixed locking mechanism between the standpipe and the adjustment tube is a bolt with an operating handle. Tighten the standpipe to achieve a fixed position with the adjustment pipe. However, after long-term use of this locking method, the thread of the bolt is prone to wear and tear, which will cause the standpipe to loosen and cause a safety accident. In response to the above defects, a method has been developed that uses the end face of the locking block to tighten the standpipe so as to secure the standpipe firmly. However, after long-term use of this structure, the e...

[0002] At present, the standpipe and adjustment tube used in fitness equipment are mainly used for height adjustment at the handlebars and seat cushions. The common fixed locking mechanism between the standpipe and the adjustment tube is a bolt with an operating handle. Tighten the standpipe to achieve a fixed position with the adjustment pipe. However, after long-term use of this locking method, the thread of the bolt is prone to wear and tear, which will cause the standpipe to loosen and cause a safety accident.

In response to the above defects, a method has been developed that uses the end face of the locking block to tighten the standpipe so as to secure the standpipe firmly. However, after long-term use of this structure, the end face of the locking block is easy to wear, resulting in a mismatch between the locking block and the standpipe. , making it impossible to lock the riser
