Abstract
The utility model is a locking device which can adjust the height up and down freely, relating to the tightening structure technique. The utility model comprises a lock nip and a vertical post; wherein, the lock nip comprises a semicircle nip, a taper nip, a nip cover and a lock button. Both the semicircle and the taper nip are semicircle opened and provided with cuttage grafting tooth which cooperated with each other respectively. After the cooperated semicircle nip and the taper nip blocked on the vertical post, a U shaped nip cover is arranged on the outer, and a pin axes is arranged at the cut as well as the lock button is arranged on the pin axes. The utility model is simple structured, convenient for using and can random adjust the height.
Description
Technical field
The utility model relates to mechanical field, but the particularly fastening structure of regulated at will height
Correlation technique.
Background technique
The lowering or hoisting gear of can regulate height is the structure of using always, as the elevating scaffold at building field.Raising platform in people's daily life, lifting frame etc., all indispensable.Existingly heighten low device, mainly contain the plughole regulative mode of lattice one lattice; Also has the screw rod regulative mode; Also have a section tube-inserted type regulative mode etc., these regulative modes are to have reached to regulate the height purpose, regulate complicatedly but have respectively, waste time and energy, can not step-less adjustment etc. the deficiency of aspect.
Technology contents
The utility model purpose is at the deficiencies in the prior art, design a kind of simple in structure, easy to adjust, but and the locking device of step-less adjustment height.
The utility model purpose can be achieved through the following technical solutions.
A kind of locking device of can regulate height comprises locking folder and mullion, and described locking folder comprises half garden intermediate plate, cone-shaped clip, chuck and snap close.Half garden intermediate plate and cone-shaped clip are the semicircle type of opening, be respectively equipped with the grafting tooth that cooperatively interacts on it, after half garden intermediate plate and cone-shaped clip cooperatively interact and are stuck on the mullion, the outside is with chuck, and chuck is " U " shape part, and opening is provided with a bearing pin, the set shaft hole sleeve of snap close front end is on lock shaft, the snap close top is provided with a snap close when bearing pin rotates, but the involute surface of snap close push-tight cone-shaped clip, and the other end is provided with the adjusting handle.The locking device of can regulate height, for ease of installing, the set axis hole of described snap close front end is the semiaxis hole that an opening is arranged, the semiaxis hole can be socketed on the lock shaft.The locking device of can regulate height, fastening for clamping, described mullion is provided with anti-slip tank or anti-skidding joint.
The present technique advantage is, and is simple in structure, regulate easy to use, but step-less adjustment.
