Abstract

The utility model discloses a door stopping mechanism of door closing hinge, which comprises an outer sleeve, an inner sleeve, a core axle, a spring, a regulating nut and a location mechanism. The inner sleeve is positioned between the core axle and the outer sleeve, and at least two blocks are spliced to form the inner sleeve. The inner surface of the inner sleeve and the outer surface of the core axle are provided with an axial direction rib. The interface of the outer sleeve and the inner sleeve is designed into a conical surface, the spring sheathed on the core axle is positioned on the inner sleeve, the regulating nut is sheathed on the core axle and is matched with the outer sleeve by screw threads, and the location mechanism can cause the inner sleeve not to rotate and to move along the axial direction. The utility model has the advantages of small abrasion, small noise in the door closing process, reliable door stop and long service life, and the door stop force can be regulated.

Description

The door stop mechanism of door closing hinge

Technical field

The utility model relates to the braking device of door leaf, particularly the door stop mechanism of door closing hinge.

Background technology

At present; the door stop mechanism that a kind of door closing hinge is arranged be mandrel and outside put two concave cylindrical be set respectively; be equipped with the annular cover between mandrel and the overcoat; annular puts and is provided with two axial rollers; when opening the door, the rotary resistance that the fin that constitutes by roller and mandrel, the concave cylindrical that puts is outward wiped generation mutually reaches door and stops purpose.Advantage is when just having brought into use, and door stops effective.It is unadjustable that weak point is that door stops the power size; Rubbing noise is big mutually with fin for roller during use; Easy to wear, along with the passing of service time, may wear to a certain degree, door stops and can lose efficacy.

The utility model content

The purpose of this utility model is in order to overcome above-mentioned deficiency, provides a kind of door to stop the door stop mechanism of the little door closing hinge of power adjustable size, wearing and tearing.

In order to achieve the above object, the door stop mechanism of door closing hinge of the present utility model comprises overcoat; Also comprise interior cover, mandrel, spring, adjusting nut and make in cover can only move axially and the detent mechanism that can not rotate, interior cover is put together by two at least, between mandrel, described overcoat, inner surface of inner race, mandrel external surface are provided with axial fin, interior cover is designed to taper seat with the contact surface of overcoat, spring housing puts on mandrel, in being seated in, and adjusting nut is enclosed within on the mandrel and cooperates with sleeve thread.

Detent mechanism described in the utility model is made up of fixedly connected locating piece on the coat, and the quantity of locating piece equates with described interior cover amalgamation number of blocks.

The utility model is owing to adopted said structure, adjusting nut can strengthen or reduce the internally pressure of cover of spring, She Ji fin, taper seat make door stop the power adjustable size in addition, fin does not contact mutually when opening the door, and wearing and tearing reduce, owing to be provided with spring, make Men Kaizhi door off-position put or put that noise is little at closing time by the door off-position, fin may wear to a certain degree also can be readjusted door by adjusting nut and stop power, long service life, and door stops reliable.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is an A-A sectional view among Fig. 1.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As shown in Figure 1, 2, the door stop mechanism of the utility model door closing hinge comprises adjusting nut 1, spring 2, overcoat 3, screw 4, interior cover 5, detent mechanism, screw 7, mandrel 8.The interior cover 5 of present embodiment is put together by two, cover 5 can radial displacement in making, detent mechanism is made of the locating piece 6 that is fixedly connected on the overcoat 3, the quantity of locating piece 6 is identical with interior cover 5 amalgamation numbers of blocks, also be two, cover 5 can only move axially and can not rotate in making, interior cover 5 is placed in mandrel 8, between the overcoat 3, cover 5 inner surfaces in two, the mandrel external surface is provided with axial fin, interior cover 5 is designed to taper seat with the contact surface of overcoat 3, spring 2 adopts dish spring kink on mandrel 8, on the cover 5, adjusting nut 1 is enclosed within on the mandrel 8 and overcoat 3 threaded engagement in being seated in.When cooperating with door closing hinge, overcoat 3 is fixedlyed connected with a page or leaf sheet of hinge, mandrel 8 is fixedlyed connected with another page sheet of hinge, and screw 4 is by screw closing a mechanism or close a speed adjusting gear and match door stop mechanism and hinge.Door stops power and regulates as follows: make dish spring 2 press to interior cover 5 by adjusting nut 1, in cover 5 do axial displacement along the elastic force direction, simultaneously since designed taper seat make in cover 5 simultaneously radially to the axle center displacement, cover 5 is pressed to mandrel 8 in making, when opening the door, mandrel 8 rotates with hinge page or leaf sheet, fin on fin on the mandrel 8 and the interior cover 5 joins, cover is outer in making expands, move at axis direction along the conical surface simultaneously, further compact disc spring 2 because of dish spring 2 is pressed on the interior cover 5 by adjusting nut, further strengthens the rotary resistance of 5 pairs of mandrels 8 of interior cover, adjust adjusting nut 1, cover 5 stops the size of mandrels 8 rotary resistances in can adjusting, and adjusts that suitable to make door reach certain position motionless, reaches to stop purpose.
