Embodiment 1

[0013] Example 1. A single-knob adjustable locking positioning mechanism, such as Figure 1-Figure 2 shown. It comprises fixed square tube 1, the overcoat square tube 2 that is sleeved on the fixed square tube 1, has a row of positioning holes 23 on the fixed square tube 1, has a screw hole 24 on the overcoat square tube, and knob is installed in the screw hole 24. Lining plate 10 and reinforcing plate 11 are fixed successively on the outer square tube 2, and screw hole 24 is positioned on reinforcing plate 11, has the hole 22 concentric with screw hole 24 on the lining plate 10 and outer outer square tube 2. A U-shaped seat 3 is also fixed on the outer square tube 2, and a base 4 for installing movable parts is fixed on one side of the U-shaped seat 3, and two left and right bolt shafts 6 and 6 are fastened between the two side plates of the U-shaped seat 3. nut 21. A liner 5 is sleeved in the middle of the left and right bolt shafts 6 , and two inward levers 7 are respect...

Abstract

The invention relates to a single-knob adjusted locking and positioning mechanism which belongs to a mechanical and body-building apparatus mechanism. The single-knob adjusted locking and positioning mechanism comprises a fixed square pipe, an outer sleeved square pipe, a lining plate and a reinforcing plate, wherein a row of positioning holes are arranged on the fixed square pipe; a screw hole is positioned on the reinforcing plate, and a knob is installed in the screw hole; a U-shaped seat is fixed on the outer sleeved square pipe; a base is fixed at one side of the U-shaped seat, and two bolt shafts and nuts are fastened between two side plates of the U-shaped seat; a lining pipe is respectively sleeved in the two bolt shafts, and two levers are installed at both ends of the lining pipe; the levers are provided with spring seats, and springs are sleeved on the spring seats; the knob comprises a screw rod and a handball; and a press plate which is positioned under the neck end of the handball and presses the levers is sleeved on the screw rod. The invention has the advantages of simple structure, lower production cost, single knob operation, convenient operation, locking and precompression positioning effect and high adjusted position precision and reliability and can be widely applied to a mechanical and body-building apparatus in which the opposite position of two parts is needed to be adjusted.

Description

technical field [0001] The invention belongs to the technical field of machinery and fitness equipment mechanisms, and more specifically relates to the design innovation of a locking and positioning mechanism for single-knob adjustment of mechanical equipment such as fitness equipment. Background technique [0002] In fitness equipment and other mechanical devices, adjustment and positioning mechanisms for adjusting the relative positions of two components are widely used. [0003] The traditional adjustment and positioning mechanism includes a standpipe fixed on the main frame of the fitness equipment, a sliding pipe sleeved in the standpipe, and an adjustment live bolt inserted in the standpipe and the sliding pipe. The standpipe has holes and the slide tube has a row of holes. Pull out adjusting live bolt, insert in the hole on the standpipe and another hole in a row of holes on the slide pipe, just adjusted the relative position of standpipe and slide pipe. The structu...
