Description

Door pivot device

The utility model relates to a kind of door pivot device of autoamtic, is meant a kind of upper end and bottom that the upper sheet space and the base piece of upper and lower hingen all are fixed on door-plate especially, makes door-plate installing and all very simple and rapid door pivot device of autoamtic of dismounting.

Generally commonly use the hingen structure that door-plate is installed, it is to use a kind of hinge of two superposed types to be fixed on the door-plate mostly, wherein be equipped with the guide hole that several run through on the plate of each hinge, be fixed on the doorframe or the lateral margin position of door-plate for penetrating hold-down screw, this kind installing hinge is as the mode of occupation of door-plate hingen, it must carefully aim at the position of door-plate in doorframe when installing, so operation is very difficult, in case and desire dismounting door-plate is when repairing, desire is taken off hold-down screw from hinge, also be very difficult, this uses and one of goes up big shortcoming for generally commonly using hingen structure.

The purpose of this utility model is to provide a kind of door pivot device of autoamtic, and when making the hingen installing, door-plate and metope aligned position are very easy, and during desire dismounting door-plate, the latch of going up in the hingen set screw need only be taken off, and unload set screw, can pull down door-plate easily, easy to operate quick.

The purpose of this utility model reaches as follows:

A kind of door pivot device of autoamtic, it is characterized in that: it comprises hingen and following hingen, following hingen comprises a joint chair and a base piece, joint chair one end that is fixed on metope stretches forward and forms outstanding end, its central authorities are equiped with the fixedly guidance in axle center of guiding, this guidance is inserted in the base piece that end bending central authorities form guide hole, and this base piece is fixed on the bottom edge of door-plate; Last hingen then comprises the upper sheet space that is fixed in the doorframe position and is fixed on the lower sheet space of ora terminalis on the door-plate, the jag central authorities of this upper sheet space bending form guide hole, be equiped with a location bolt in the guide hole, and be inserted in lower sheet space, and in the little guide hole of positioning bolt, insert a latch and make upper and lower plate pivot knot one.

The utility model has the advantages that: door-plate and metope aligned position are very easy during the utility model installing, and during desire dismounting door-plate, the interior latch of positioning bolt that only needs to go up hingen takes out, and can dismantle door-plate easily, and installing or disassembling section are all very quick and convenient.

Illustrate as follows:

Fig. 1 is the hingen organigram of going up of the present utility model.

Fig. 2 is a hingen organigram down of the present utility model.

Fig. 3 is a user mode schematic diagram of the present utility model.

The utility model will be described in further detail as follows in conjunction with the accompanying drawings: with reference to Fig. 1, last hingen comprises upper sheet space 100 and lower sheet space 104, there is the jag 101 of bending in upper sheet space 100 the place aheads wherein, there is a guide hole 102 in these jag 101 central authorities, and the plate position of upper sheet space is arranged with several perforation that runs through 103, for penetrating fixed screw upper sheet space 100 is fixed on doorframe upper limb position, lower sheet space 104 its front ends also form the jag 105 of a bending relatively, this jag central part also is provided with a guide hole 105a, bore a hole 106 and also be arranged with several on the plate of lower sheet space 104, can be for penetrating fixed screw in door-plate upper end edge portion position, and when upper sheet space is nested with one mutually instantly, be to lock a location bolt 107 in mode from bottom to top, wherein there is a little guide hole 108 that runs through positioning bolt 107 upper ends, and can make up and down that plate can't separate for placing a mortise lock.

Figure 2 shows that down the organigram of hingen, following hingen comprises a joint chair 200 and a base piece 204, one for a joint chair 200 that is installed on the metope as seen from Figure 2, this joint chair stretches forward and forms an outstanding end 201, its central authorities form the fixedly guidance 202 in axle center of a guiding, be arranged with several perforation 203 on the plate of joint chair 200, can joint chair 200 be fixed on the doorframe for penetrating fixed screw, and the front end of another base piece 204 forms the jag 205 of bending, the jag central part is provided with a guide hole 206, can supply to be inserted in and on the guidance on the joint chair 200, make base piece 204 be the center left-right rotation according to this, and also be arranged with several perforation 206 on the plate of base piece 204, can base piece 204 be fixed on the root edge position of door-plate for penetrating fixed screw.

Figure 3 shows that user mode schematic diagram of the present utility model, by finding out very clearly among the figure that the upper sheet space 100 of going up hingen sets firmly on the doorframe, and lower sheet space 103 is installed in the situation at door-plate upper limb position, the joint chair 200 of following hingen then is to be installed on the doorframe, and base piece 204 is installed in the root edge position of door-plate, the above-mentioned work that sets firmly is that prior location hammers into fixed screw respectively when door-plate still is unkitted into doorframe, must not relocate when therefore door-plate is packed into, the guide hole 206 of base piece 204 is inserted in the guidance 202 of joint chair 200, and penetrate with positioning bolt 107 in the guide hole of upper sheet space 100 and lower sheet space 104, one latch is inserted in the little guide hole 108 of positioning bolt 107, can finish the work of installing door-plate, the very rapid convenience of process.
