Description

A kind of elastic adjustable articulation attachment device

Technical field

The utility model is related to model interconnection technique fields, more particularly to a kind of elastic adjustable articulation connection dress It sets.

Background technology

In daily life, various animals and manikin are seen everywhere, and are had plenty of for ornamental model, have plenty of for Convenient for the tool of displaying clothing, in use, Most models are fixed, joint is unable to rotational transform.Have Can cradle head general there will be two kinds of situations, one of which is exactly that the comparison that connects is loose, slightly touches and is all likely to occur Rotation cannot be fixed on some specific posture, and another kind is exactly too tight, need to need demounting bolt again when rotation every time Assembling, it is cumbersome.

Utility model content

Shortcoming in for the above-mentioned prior art, the utility model provide a kind of elastic adjustable articulation company Connection device is inconvenient to adjust to solve the problems, such as that joint connection is elastic in the prior art.

The utility model provides a kind of elastic adjustable articulation attachment device, including bolt, nut, elastic block, First connector, the second connector, first connector, the second connector are connected by the bolt and nut cooperation It connects, one end of the bolt is provided with connection shaft, and the elastic block is rotatably connected in the connection shaft.First connection Head is respectively arranged at the one end in two joints with the second connector, when elastic block bottom and the first connector are fair, at this point, first Connector and the relative rotation of the second connector are more flexible, the relative position between two joints can be adjusted at this time, when position tune After good, applying a power to elastic block makes elastic block to connect shaft as axis rotation, at this point, elastic block bottom can connect to first Connector or the second connector apply a pressure, further compress the junction of the first connector and the second connector so that two A joint is relatively fixed, and cannot be rotated, and when needing cradle head next time, elastic block reset.

Further include two gaskets as a further improvement of the utility model, two gaskets are set in the spiral shell On bolt, two gaskets are respectively arranged at the outside of first connector and second connector, the connection shaft It is more than the connection rotating shaft core to the gasket at a distance from the contact point of the gasket when axle center is rotated to the elastic block Vertical range.It can be effectively protected the first connector and the second connector by the way that gasket is arranged, made when preventing from tightening nut At damage, it is also possible to directly apply pressure to the first connector or the second connector when elastic block being avoided to rotate, to first Connector or the second connector damage.

Further include shaft base as a further improvement of the utility model, the shaft base is installed on by bolt There are the side of the elastic block, the connection shaft to be set on the shaft base.By the way that shaft base is arranged so that production Assembly is simple, reduces production cost.

The shaft base is U-shaped piece as a further improvement of the utility model, the two side position of the shaft base In the opposite both sides of the nut of the bolt, the connection shaft is relatively set on the two side of the shaft base, it is described Elastic block bottom is cavity structure, and the cavity wall of the elastic block is rotatably connected with the connection shaft.This design can make When elastic block works, increase with the first connector contact area, while stress is more uniform, possesses better locking effect.

The connection shaft is fixedly installed on the bolt as a further improvement of the utility model,.Connect shaft It is integrally formed with bolt, reduces linkage editor.

Further include tension device as a further improvement of the utility model, the tension device include drawstring, turbine, Worm screw is provided with the thread groove with the gear cooperation on the turbine on the worm screw, and described drawstring one end connects with the turbine It connects, the other end of the drawstring is connect with the elastic block.When work, rotary worm, worm screw drives turbine rotation, turbine rotation Drawstring is tensed, drawstring pulls elastic block rotation to achieve the purpose that locking, and when worm screw, which turns round, to be resetted, drawstring loosens, and elastic block is multiple , it can be rotated between joint.

Knob, the knob and the worm screw are provided at the top of the worm screw as a further improvement of the utility model, It is fixedly connected.By the way that knob is arranged so that rotation is more convenient laborsaving.

The drawstring is connect with the top of the elastic block as a further improvement of the utility model, the elastic block Distance is more than the distance between the connection shaft and the elastic block bottom between top and the connection shaft.In this way may be used So that power arm is more than resistance arm, reach labour-saving effect.

The elastic adjustable articulation attachment device of one kind provided by the utility model, is provided with elastic block, works as elastic block It when not working, relatively flexible can be rotated between two joints, when two joints are adjusted to suitable position, rotation is elastic Block applies pressure to the connector in two joints, and then locks the junction in two joints so that and joint will not arbitrarily rotate, , only need to be by elastic block reset when needing rotation next time, the design structure is simple, and operation is easy, and realizes two It connects and elastic freely adjusts between joint.
