Description
Technical field
The utility model belongs to the body-building apparatus technical field, more particularly relates to the improvement of the bench height adjusting mechanism of body-building apparatus.
Background technology
Traditional bench height adjusting mechanism that is used for bicycle mostly by be fixed on standpipe on the vehicle frame, be sleeved on the sliding tube of standpipe, turn-buckle and the fastener thereof that is fixed on the seat cushion of sliding tube upper end and is installed in the standpipe upper end formed.The standpipe upper end open of turn-buckle is installed.When need adjusting height, only need unclamp turn-buckle, it is highly suitable that sliding tube is injected from standpipe or extracts together with seat cushion, turn-buckle tightened to get final product again.
The bench height adjusting mechanism that in the past was used for body-building vehicle mostly by be fixed on inclined tube on the body-building vehicle body frame, be sleeved on inclined tube sliding tube, be fixed on the seat cushion anchor shaft of sliding tube upper end and be installed in inclined tube and sliding tube between the adjustment knob formed.Can be to have row's screw on holes on the inclined tube, the sliding tube.The hole that the adjustment knob of band screw rod passes on the inclined tube is tightened in the different screws of sliding tube, has just adjusted the differing heights of seat cushion.
Above-mentioned two kinds of height adjustment mechanism structure are simpler, but trouble when adjusting.Ride or the body builder can't ride over top adjustment, needing stops earlier gets off, and recovers after adjusting to use again.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of bench height adjusting mechanism of body-building apparatus is provided.It is not only simple in structure, and it is also very simple to adjust operation.Need not stop gets off can adjust, and uses very convenient.And use is safer, can auto lock.
In order to achieve the above object, the utility model comprise the inclined tube that is fixed on the body-building vehicle body frame, be sleeved on sliding tube in the inclined tube, be fixed on the sliding tube upper end the seat cushion anchor shaft, be installed in the seat cushion on the seat cushion anchor shaft and be installed in inclined tube and sliding tube on adjusting mechanism.The inclined tube front has the highly different hole of a row, and the front, top and the bottom of sliding tube respectively has an elongated slot.Adjusting mechanism is by the permanent seat that is fixed on the sliding tube upper back, to be pivotally mounted in the last movable tongue that its front end stretches out from the top elongated slot on the permanent seat, with upper pin and last movable tongue bonded assembly connecting rod, be installed in the compression spring between seat cushion anchor shaft lower surface and the small end face, be welded on the shaft bearing plate of elongated slot both sides, sliding tube bottom, be installed in the little axle on the Y-axis board, the following movable tongue that is installed in that little axle is gone up and stretches out from sliding tube bottom elongated slot and connect down that the lower bearing pin of movable tongue and connecting rod constitutes.
A locking pin is being fixed in the front portion of movable tongue down.The length of locking pin is less than the width of inclined tube square hole but greater than the width of sliding tube bottom elongated slot.This structure is positioned outside the sliding tube movable tongue front end all the time, avoids it to enter and causes adjusting error in the sliding tube.
Cylindric spring perch is being fixed in the upper end of connecting rod, is fixing cylindric spring perch below the seat cushion anchor shaft, compression spring be installed on the cylindric spring perch and cylindric spring perch in.This structure is limited in the spring perch position of compression spring, avoids it to deviate to cause mechanism malfunctioning.
Go up the front end of movable tongue and handle with screw retention.This structure makes when adjusting convenient.
During adjustment, the body builder can still ride on the body-building apparatus.Only with hand is held handle and is upwards drawn, and the elastic force that handle just can overcome compression spring drives successively on movable tongue, upper pin, connecting rod and the lower bearing pin and moves, lower bearing pin and then force down movable tongue around little axle rotation, and the front end of following movable tongue takes in from the square hole of inclined tube.This moment, sliding tube fell in inclined tube under the effect of gravity, and the front end of following movable tongue slips over the square hole one by one of inclined tube successively, and the height of seat cushion just reduces successively.In the time of highly suitably, only need loose one's grip, under the elastic force effect of compression spring, last movable tongue can drive upper pin, connecting rod and lower bearing pin successively and move down, lower bearing pin and then force down movable tongue around the contrarotation of little axle, the front end of movable tongue is just outstanding from the square hole of inclined tube down, and sliding tube is blocked, and it is highly locked.When the body builder adjusts upward bench height, do not need to get off and adjust it highly, and, need not hold handle adjustment, only need adjust upward with hand direct pull seat cushion, when position suitable, letting go gets final product, and at this moment setting device is with auto lock.As seen, this device is upwards adjusted all very convenient quick downwards.
The utility model is not only simple in structure, it is simple to operate to adjust, and need not stop and get off and can adjust, use very convenient, can auto lock.It can be widely used in body-building vehicle and other body-building apparatus.
