Abstract
The utility model discloses an adjustable rotating resistance's revolute pair, it includes T type component, the handle external screw thread constitutes rectangular thread with T type component internal thread and is connected, spring and pressure head are adorned together in the hole of T type component, the spring is being pressed to the handle, the bottom of pressure head is being pressed to the spring, the head of pressure head and the recess contact of recess dish, the circular borehole jack of incomplete of recess dish is on L type member, the nut fastens the recess dish on L type component, the hole and the L type component clearance fit of T type component. Properties of product are improved in order to replace not adjustable rotating resistance's revolute pair to this revolute pair.
Description
Technical field
This utility model relates to the revolute pair of a kind of scalable rotational resistance, belongs to mechanical field.
Background technology
Along with the development of society, the various supports of people's utility model, medical stand as used by odontologist, but excessive frictional resistance, staff is pullled motionless, not easily operates, too small frictional resistance does not have supporting role, and this utility model can solve problems. And this patent compact conformation, there is very strong usability, and have a extensive future.
Utility model content
This utility model purpose is to provide the revolute pair of a kind of scalable rotational resistance, to replace the revolute pair of unadjustable rotational resistance, improves properties of product.
In order to realize above-mentioned technical characteristic, the purpose of this utility model is achieved in that the revolute pair of a kind of scalable rotational resistance, it includes T-shaped component, handle external screw thread constitutes rectangular thread with T-shaped component female thread and is connected, spring is contained in the endoporus of T-shaped component together with pressure head, handle press against spring, spring press against the bottom of pressure head, the head of pressure head contacts with the groove of groove dish, the incomplete circular port of groove dish is enclosed within L-type component, nut is fastened on groove dish on L-type component, and the hole of T-shaped component coordinates with L-type component space.
Described groove dish is be connected by incomplete circular port and incomplete circular shaft with L-type component, can not rotate between them.
This utility model has the advantages that:
Realizing revolute pair friction resistance force adjustable, rotary handle just can loosen or holddown spring, and then pressure head is pressed in the pressure in groove dish and will change with the power of spring and change, thus changing revolute pair to rotate required torque.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is that overall structure of the present utility model shows that complete section is intended to.
Fig. 2 is that overall structure of the present utility model shows that partial cutaway entirety is intended to.
Fig. 3 is the overall structure schematic diagram at a visual angle of the present utility model.
Fig. 4 is the overall structure schematic diagram at a visual angle of the present utility model.
In figure: T-shaped component 1, handle 2, spring 3, pressure head 4, nut 5, groove dish 6, L-type component 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
The revolute pair of a kind of scalable rotational resistance as Figure 1-4, it includes T-shaped component 1, handle 2 external screw thread constitutes rectangular thread with T-shaped component 1 female thread and is connected, spring 3 is contained in the endoporus of T-shaped component 1 together with pressure head 4, handle 2 press against spring 3, spring 3 press against the bottom of pressure head 4, the head of pressure head 4 contacts with the groove of groove dish 6, the incomplete circular port of groove dish 6 is enclosed within L-type component 7,5 groove dishes 6 of nut are fastened on L-type component 7, the hole of T-shaped component 1 and L-type component 7 matched in clearance.Rotary handle just can loosen or holddown spring, and then pressure head is pressed in the pressure in groove dish and will change with the power of spring and change, thus changing revolute pair to rotate required torque.
Further, described groove dish 6 is be connected by incomplete circular port and incomplete circular shaft with L-type component 7, can not rotate between them.
Above-described embodiment is used for illustrating this utility model; rather than this utility model is limited; in spirit of the present utility model and scope of the claims, any amendment that this utility model is made and change, both fall within protection domain of the present utility model.
