Description

A kind of self-return adjustment structure of Pinless hinge with guide member

Technical field

The utility model relates to door Pinless hinge with guide member technical fields, and in particular to a kind of self-return adjusting of Pinless hinge with guide member Structure.

Background technique

The Pinless hinge with guide member of the prior art, only by using twist screws persistently to release power to the screw thread on the outside of torsion spring adjusting base Locking positioning is carried out, get off the screw thread continued depletion that can make on the outside of torsion spring adjusting base for a long time, leads to self-return regulating mechanism Service life reduces.

Utility model content

The purpose of this utility model is to provide a kind of self-return adjustment structures of Pinless hinge with guide member, have solved above-mentioned background The problem of being proposed in technology.

To achieve the above object, the utility model provides the following technical solutions: a kind of self-return adjusting of Pinless hinge with guide member Structure, including articulate letter, return spring, spring adjustment seat and hinge seat, return spring one end connects hinge activity Letter, one end of other end connecting spring adjustment seat, wherein the spring adjustment seat is mounted on hinge seat by the way that torsion is adjustable On mounting base, the Basolateral of the spring adjustment seat is equipped with positioning threads, and the lower section of the mounting base is equipped with location nut, The spring adjustment seat connects location nut by passing through mounting base.

Further, the bottom end of the spring adjustment seat offers adjusting screw hole.

Further, the top of the mounting base is equipped with bearing, and the spring adjustment seat is by passing through bearing and mounting base Connect location nut.

Compared with prior art, the utility model has the beneficial effects that being positioned by being added in the outside of spring adjustment seat Screw thread simultaneously connects location nut, carries out tightening positioning to spring adjustment seat using location nut, reduce to part spring adjustment seat Loss, prolong its service life, hinge seat be based on articulate cylinder rotation after, due to the recurrence power of return spring, hinge seat Meeting self-return passes through setting bearing at the top of mounting base, reduces the friction system in hinge seat and articulate cylinder motion process Number, keeps hinge seat self-return more smooth.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the configuration schematic diagram of the utility model.

In figure: articulate letter 1, return spring 2, spring adjustment seat 3, hinge seat 4, bearing 5, location nut 6, screwdriver 7, positioning threads 31, adjusting screw hole 32, mounting base 40.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing:

In the description of the utility model, it is to be understood that term " center ", " longitudinal direction ", " transverse direction ", "upper", "lower", The orientation or positional relationship of the instructions such as "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is It is based on the orientation or positional relationship shown in the drawings, merely to making sub- description the utility model and simplifying description, rather than indicates Or imply that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot understand For limitations of the present invention.

A kind of self-return adjustment structure of Pinless hinge with guide member as shown in Figure 1 to Figure 2, including articulate letter 1, return bullet Spring 2, spring adjustment seat 3 and hinge seat 4,2 one end connects hinge activity letter 1 of return spring, other end connecting spring adjustment seat 3 One end, wherein spring adjustment seat 3 passes through the adjustable mounting base 40 being mounted on hinge seat 4 of torsion, spring adjustment seat 3 Basolateral is equipped with positioning threads 31, and the lower section of mounting base 40 is equipped with location nut 6, and spring adjustment seat 3 is by passing through mounting base 40 connection location nuts 6.

As above, the bottom end of spring adjustment seat 3, which offers, adjusts screw hole 32, adjusts screw hole 32 by using screwdriver 7 is corresponding Carry out cooperation adjustment spring adjustment seat 3.

As above, the top of mounting base 40 is equipped with bearing 5, and spring adjustment seat 3 connects and determines by passing through bearing 5 and mounting base 40 Position nut 6 reduces the coefficient of friction in hinge seat and articulate cylinder motion process through setting bearing at the top of mounting base, Keep hinge seat self-return more smooth.

Working principle of the utility model is: by by a kind of self-return adjustment structure of Pinless hinge with guide member of the utility model The return structure for replacing existing Pinless hinge with guide member is locked by the positioning threads 31 and location nut 6 of 3 Basolateral of spring adjustment seat Fixed to be positioned, position fixing process by screwdriver 7 twists the adjusting screw hole 32 of 3 bottom end of spring adjustment seat locking is adjusted, The loss to part spring adjustment seat 3 is reduced, is prolonged its service life.

After hinge seat 4 is based on the rotation of articulate cylinder, due to the recurrence power of return spring 2, hinge seat 4 understands self-return, By setting bearing 5 at 40 top of mounting base, the coefficient of friction in hinge seat 4 and articulate cylinder motion process is reduced, makes to cut with scissors 4 self-return of chain seat is more smooth.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replace and deform, the scope of the utility model is limited by appended claims extremely equivalent.
