Abstract

The utility model relates to a door hinge comprising a hinge back base which is fixedly connected with a housing and a hinge front base which is fixedly connected with a door body. The door hinge is characterized in that the door hinge further comprises a hinge mechanism and a torsion spring; and the hinge mechanism is pivoted with the hinge back base and the hinge front base, and the torsion spring is matched with the hinge mechanism and the hinge back base. Due to the adoption of the structure, the side end surface of the door body and the housing or a box body are separated with a certain distance when the door body rotates relative to the housing or the box body, thereby overcoming the defect that when the housing or the box body is in adjacent arrangement of more than two parts, the certain distance or a large distance needs to be separated in the prior art, and reducing the occupied space. The door hinge can prevent the door body from being opened automatically due to the pulling action of a hinge.

Description

A kind of door hinge

Technical field

The utility model relates to a kind of door hinge, especially relates to a kind of hinge that cabinet or casing and door body use that is used for.

Background technology

Present prior art, a kind of door hinge comprise the hinge back seat of fixedlying connected with housing, hinge front stall, hinge front stall and the pivot joint of hinge back seat of fixedlying connected with the door body.Existing problems are: when moving, the door body is opened automatically, and when two housings or casing placed adjacent were arranged, spacing distance was big.

Summary of the invention

The purpose of this utility model is: a kind of door hinge is provided, and when it can prevent to move, the door body was opened automatically; And when two housings or casing placed adjacent, spacing distance is little.

The utility model be achieved in that a kind of door hinge comprise the hinge back seat of fixedlying connected with housing, with the hinge front stall that the door body is fixedlyed connected, its special character is: also comprise a linkage, a torsion spring; Linkage and hinge back seat, hinge front stall articulate, and torsion spring cooperates with linkage, hinge back seat.

Described a kind of door hinge, its special character is: described linkage is made of back stay, front tension bar, and back stay one end and the pivot joint of hinge back seat, the other end and hinge front stall articulate; Front tension bar one end and hinge back seat articulate, and the other end and hinge front stall articulate; Torsion spring is by the pivot joint of a spring pivot pin and hinge back seat, and torsion spring one end and back stay are slidingly matched, and the other end cooperates with steady pin on being fixed on the hinge back seat.

Described a kind of door hinge, its special character is: described front tension bar is by pull bar and connecting lever is one-body molded makes, and the end of pull bar and hinge back seat articulate, the end of connecting lever and the pivot joint of hinge front stall.

Described a kind of door hinge, its special character is: the pull bar of described front tension bar is curved.

Described a kind of door hinge, its special character is: described front tension bar is made of stacked being fixed together of preceding pulling-on piece body of two or two above sheets; Described back stay is made of stacked being fixed together of post-tensioning lamellar body of two or two above sheets.

A kind of door hinge of the utility model owing to adopt such structure, when the door body rotates with respect to housing or casing, the side end face of door body and housing or casing interval certain distance; Overcome in the prior art, when housing or casing by more than two during adjacent the setting, need keep at a certain distance away or defective that spacing distance is big, reduced taking up room.Because hinge draws the effect of pulling, can prevent that the body from opening automatically.

Fig. 3 is a rear elevation of the present utility model.

When Fig. 4 is the utility model use, the sectional view of deployed condition.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As Fig. 1, Fig. 2, shown in Figure 3, a kind of door hinge comprise the hinge back seat 1 of fixedlying connected with housing, with the hinge front stall 2 that the door body is fixedlyed connected, also comprise a linkage, a torsion spring 5;

Linkage and hinge back seat 1, hinge front stall 2 articulate, and torsion spring 5 cooperates with linkage, hinge back seat 1.

Described linkage is made of back stay 3, front tension bar 4, and back stay 3 one ends and 1 pivot joint of hinge back seat, the other end and hinge front stall 2 articulate;

Front tension bar 4 one ends and hinge back seat 1 articulate, and the other end and hinge front stall 2 articulate;

Torsion spring 5 articulates by a spring pivot pin 51 and hinge back seat 1, and torsion spring 5 one ends and back stay 5 are slidingly matched, and the other end cooperates with steady pin 6 on being fixed on hinge back seat 1.

As Fig. 2, shown in Figure 4, described front tension bar 4 is by pull bar 41 and connecting lever 42 one-body molded making, and the end of pull bar 41 and hinge back seat 1 articulate, and the end of connecting lever 42 and hinge front stall 2 articulate.

The pull bar 41 of described front tension bar 4 is curved.

Front tension bar 4 constitutes by the preceding pulling-on piece of several sheet is stacked.Front tension bar 4 can be made of two stacked being fixed together of preceding pulling-on piece, also can be by constituting more than two.

Back stay 5 constitutes by the rear tab of several sheet is stacked.Back stay 5 can be made of two stacked being fixed together of rear tab, also can be by constituting more than two.

The utility model in use, as shown in Figure 2, hinge front stall 2 rotates counterclockwise, front tension bar, back stay rotate with respect to hinge back seat 1, and the hinge front stall rotates relative to forward and backward

pull bar

3,4, after hinge front stall 2 rotates 90 degree, as shown in Figure 4, hinge front stall 2 is vertical with hinge back seat 1, and to the orientation away from the hinge back seat, has moved a segment distance.When being installed in housing or casing, a segment distance has just been moved with respect to housing or casing in the side end face of door body, has prevented the housing that Men Tiyu is adjacent or the phase mutual interference of casing, thereby realizes between adjacent two housings or the casing that apart from little, little purpose takes up room.
