Thus, the door shaft assembly of the utility model has the advantages of simple and convenient installation and low cost; in addition, when the door shaft assembly of the utility model is adopted on the door, the moving flexibility of the door is enhanced, the rigidity of a front door is improved and the centering of a moving shaft of the door is accurate.
Description
Technical field
The utility model relates to a kind of mechanical device that is used for fixing door, relates in particular to a kind of door-hinge assembly.
Background technology
Communication equipment is placed in the rack usually, and described rack is made of frame, Qianmen and side door etc. usually.Qianmen and side door are installed on the frame by door-hinge usually.For maintain communications equipment, need often to open Qianmen and/or side door, thereby make Qianmen and/or side door often open and/or close by dialling slotting door-hinge.
In the prior art, Door of communication apparatus cabinet and/or side door can be installed on the frame by following two kinds of structures: hinge structure and world latch structure, wherein commonly used is world latch structure.In the latch structure of the world, door is fixed on door on the frame by movable door-hinge.The movable door-hinge of world latch structure commonly used at present is described below as depicted in figs. 1 and 2.
Door-hinge comprises: handle 101, and it is used to hand, so that spur door-hinge downwards, door is separated with frame, thus the On/Off door; Column part 103, it is positioned at the door-hinge end, is used for inserting frame, so that door is fixed on the frame; Door-hinge middle part 102, it passes door-hinge frame 104 between handle 101 and column part 103, and described door-hinge frame 104 is welded on the door; And spring 105, it is enclosed within described door-hinge middle part 102, so that door-hinge is positioned on the frame.
Therefore,, to reserve bigger gap between gap slot 106 and the door-hinge, just can make door-hinge upper and lower pull under the spring force effect, like this, just make that the pulling up and down of door is dumb to guarantee the installation of door-hinge because door-hinge adopts gap slot 106 that door-hinge is installed.In addition, because door-hinge frame 104 adopts welding manner to be installed on the door-plate, the welding location is inconvenient, also makes the structural stability of door-hinge poor.
In addition, because door-hinge adopts gap slot 106 that door-hinge is installed, the pedestal of door-hinge rocks easily, causes door-hinge to rock.Particularly with the Qianmen of this structure after installing on the frame because the effect of Qianmen gravity, deflection can take place in pivot pin, causes the revolution axle center above the Qianmen to change, when rotate on frame at the Qianmen or lock-out state shake.Structure centering is inaccurate, rocks easily.
Moreover, because the pivot pin length of door-hinge is bigger, need bigger installing space, simultaneously in order to guarantee the installation of door-hinge, need be on door-plate local gap, not only influence the attractive in appearance of Qianmen, but also can influence the rigidity at Qianmen.
The utility model content
The purpose of this utility model provides a kind of door-hinge assembly, and it does not influence the rigidity and easy for installation of door.
The utility model discloses a kind of door-hinge assembly, described door-hinge assembly comprises: door-hinge pedestal and pivot pin; Described door-hinge pedestal comprises cylindrical hole part and back board part, and back board part is fixed on the door; Described pivot pin is installed on the cylindrical hole part of door-hinge pedestal, and can partly move up and down along cylindrical hole.
Described door-hinge assembly also comprises spring, and it is enclosed within on the pivot pin, and an end of described spring is installed on the pivot pin, and the other end is stuck on the door-hinge pedestal, and pivot pin is projected upwards.
Described pivot pin comprises handle portion and latch part, and described handle portion and plug pin portion are divided into " L " type.
The back board part of described door-hinge pedestal is provided with two bolts hole, utilizes bolt by described two bolts hole the door-hinge pedestal to be fixed on the door.
The back board part of described door-hinge pedestal is provided with a plurality of bolts hole, utilizes bolt by described bolt hole the door-hinge pedestal to be fixed on the door.
The cylindrical hole of described door-hinge pedestal partly is two sections that separate.
Described spring is arranged between two cylindrical hole parts.
Therefore, door-hinge assembly of the present utility model is installed simple and convenient, and cost is lower.In addition, on door, adopt door-hinge assembly of the present utility model, not only can improve the activity flexibility ratio of door, improve the rigidity at Qianmen, but also can make a movable axis centering accurately.

Embodiment
Understand and realization the utility model for the ease of persons skilled in the art, now describe embodiment of the present utility model in conjunction with the accompanying drawings.
As shown in Figure 3 and Figure 4, the utility model provides a kind of door-hinge assembly, comprising: door-hinge pedestal 1, and it comprises cylindrical hole part 5 and back board part 4, and cylindrical hole part 5 is used to install pivot pin 2, and door-hinge pedestal 1 is fixed on the door by backboard 4; Pivot pin 2, it is " L " shape, described pivot pin 2 is installed in the door-hinge pedestal 1 by being inserted in cylindrical hole part 5, and can move up and down along cylindrical hole part 5; And spring 3, it is enclosed within on the described pivot pin 2, so that pivot pin 2 is projected upwards, thereby door is positioned on the frame.Described door-hinge assembly adopts the five metals mould molding, and door-hinge pedestal 1 adopts two sections concentric column bore portions 5 to guarantee that pivot pin 2 upper and lower pulls and rotation process axle center are not offset, rock.Describe door-hinge assembly of the present utility model below in detail.
Door-hinge pedestal 1 is equipped with pivot pin 2 on it, described door-hinge pedestal 1 comprises: cylindrical hole part 5, it makes pivot pin 2 move up and down along two sections cylindrical hole parts 5, so that pivot pin 2 inserts on the frame or from frame transfer to,, preferably cylindrical hole partly is set to two sections circular holes according to the utility model; Back board part 4, back board part 4 is provided with bolt hole 8, and available bolt is fixed on door-hinge pedestal 1 on the door by bolt hole 8, according to the utility model, two bolts hole 8 is set on backboard preferably.
Because the door-hinge assembly adopts pedestal, pivot pin, spring and screens structure to assemble, structure itself is easy to assembly, and structure only need adopt two screws promptly to finish installation on Door of communication apparatus cabinet as a whole simultaneously, need not adjustment.Because adopt whole structure, movable door-hinge installation position does not need gap on the Door of communication apparatus cabinet, has improved the integral rigidity at Qianmen.
Because the cooperation that the movable door-hinge of part of the cylindrical hole on the pedestal of door-hinge assembly and column type is hole and axle, structure is flexible.
Adopt the door-hinge structure of door-hinge and base combination, can be applied to very little installing space.
Because the dodge gate shaft assembly adopts five metals mould molding pedestal, pivot pin adopts round steel processing, and the additional springs standard component is with low cost.
Therefore, door-hinge assembly of the present utility model is installed simple and convenient, and cost is lower.In addition, on door, adopt door-hinge assembly of the present utility model, not only can improve the activity flexibility ratio of door, improve the rigidity at Qianmen, but also can make a movable axis centering accurately.
Though described the utility model by embodiment, but those of ordinary skills know, under the situation that does not break away from spirit of the present utility model and essence, just can make the utility model that many distortion and variation are arranged, scope of the present utility model is limited to the appended claims.
