Description

A kind of hinge

Technical field

The utility model relates to a kind of hinge.

Background technology

Hinge is the device that door can naturally be rotarily opened smoothly, close. The door pivot of traditional hinge is generally located at middle part, and a side of door pivot is provided with the hinge bodies being fixed on door leaf, and opposite side is provided with the hinge seat being fixed on doorframe. Because door pivot is located at middle part, close after door leaf between door leaf and doorframe easily gap, the sealing of impact door.

Utility model content

The utility model is intended to overcome above-mentioned the deficiencies in the prior art, discloses a kind of hinge of good seal performance.

The utility model is achieved through the following technical solutions above-mentioned purpose:

A kind of hinge, for being rotatably connected of door leaf and doorframe, is characterized in that, comprise hinge bodies, door pivot cover and door pivot, one end of described hinge bodies is fixing with described door pivot cover after twice bending, and hinge bodies forms doorframe and dodges groove at flex area place, be also provided with bolt hole in hinge bodies; On an edge of described doorframe, have slotted eye, door pivot is located in slotted eye.

Preferably, the groove depth that described doorframe is dodged groove is 10～16mm, and doorframe is dodged the groove width of groove close to the width of door leaf.

Preferably, described door pivot cover has 2.

Preferably, described bolt hole has 4.

Preferably, the width of described slotted eye is greater than the flex area width of hinge bodies.

The beneficial effects of the utility model are:

The door pivot of hinge described in the utility model is located in the slotted eye on doorframe, closes after door leaf, and it is tightr that door leaf and doorframe are fitted.

Brief description of the drawings

Exploded view when Fig. 1 is hinge duty described in the utility model.

Fig. 2 is the partial enlarged drawing at A place in Fig. 1.

Detailed description of the invention

For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully. In accompanying drawing, provide preferred embodiment of the present utility model. But the utility model can be realized in many different forms, be not limited to embodiment described herein.

As shown in Figure 1, Figure 2 and Figure 3, a kind of hinge 300, for being rotatably connected of door leaf 100 and doorframe 200, this hinge 300 comprises hinge bodies 330, door pivot cover 310 and door pivot 340, one end of hinge bodies 330 after twice bending and door pivot cover 310 fixing, for increasing bed knife, door pivot cover 310 has 2. Hinge bodies 330 forms doorframe and dodges groove 350 at flex area place, the groove depth L1 that doorframe is dodged groove 350 is 10～16mm, and doorframe is dodged the groove width L2 of groove 350 close to the width of door leaf 100. In hinge bodies 300, be also provided with 4 bolts hole 320. On an edge of this doorframe 200, have slotted eye 210, door pivot 340 is located in slotted eye 210. When hinge 300 is installed, first the flex area of hinge bodies 330 is stretched in slotted eye 210, and door pivot cover 310 is enclosed within on door pivot 340, for convenience of hinge bodies 300, in the interior rotation of slotted eye 210, the width of slotted eye 210 is greater than the flex area width of hinge bodies 300.

The door pivot of the utility model hinge is located in the slotted eye on doorframe, closes after door leaf, and door leaf will be fitted closelyr with doorframe.
