Abstract

A three positions safety door comprises a door leaf, a left door case and a right door case. One side of the door leaf is arranged on the right door case through a hinge, and the right side against skids of one side of the door leaf combines with the side against skids of the right door case, while the left side against skids of the other side of the door leaf combines with the side against skids of the left door case. The right side against skids of the door leaf and the left side against skids are arranged symmetrically from outdoor to indoor, the right side against skids of the door leaf is provided with a first step and second step, the width of the door leaf provided with the first step is is less than the width of the door leaf provided with the second step. The first step appears a 'T' shape and the second step appears a bevel angle shape. The utility model provides a three positions safety door which has simple production process and low cost and does not lose anti prying ability.

Description

Three-bearing is anti-forces open the door

(1) technical field

The utility model relates to a kind of anti-forcing open the door.

(2) background technology

Existing anti-forcing open the door comprises doorframe, door leaf, is a body limit at the cross section of the contact surface of door leaf and doorframe, and this body limit is that separate unit rank " T " font, this structure of double step " T " font make pry be difficult to operation, reaches the purpose of pick-proof.But for separate unit rank " T " font, double step " T " font, the effect of pick-proof, sealing is relatively poor; Someone has proposed a door body limit and has adopted a double inclined plane dihedral, possesses good pick-proof effect, but has complex manufacturing, shortcoming that cost is high.

(3) summary of the invention

For overcome existing anti-force open the door have a good high deficiency of pick-proof performance, complex manufacturing, cost, the utility model provides that a kind of production technology is simple, low anti-the forcing open the door of Three-bearing of not losing the pick-proof performance of cost.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of Three-bearing is anti-forces open the door, comprise door leaf, left-hand door frame and right doorframe, described door leaf one side is installed on the right doorframe by hinge, the right pick-proof limit of door leaf one side cooperates with the pick-proof limit of right doorframe, the left pick-proof limit of door leaf opposite side cooperates with the pick-proof limit of left-hand door frame, the left pick-proof limit of described door leaf and the limit balanced configuration of right pick-proof, from outdoors in door, the right pick-proof limit of described door leaf is provided with first step successively, second step, the door leaf width at first step place is bigger than the door leaf width at second step place, described first step is " T " font, and described second step is the inclined-plane dihedral.

Further, the angle of slope of described chamfered angle is 45 °～60 °.

Further again, the outerplanar of described door leaf is lower than the outerplanar of doorframe.

Anti-forcing open the door of the present utility model, at closing time, door leaf contacts earlier with the doorframe second step, " T " font contacts again, and the vertical outerplanar of adding whole door leaf is lower than the vertical outerplanar of doorframe, and pry is difficult to operation, thereby reach dual pick-proof, the effect of double seal.

The beneficial effects of the utility model mainly show: 1, simple, the low pick-proof performance of not losing of cost of production technology; 2, the vertical outerplanar of whole door leaf is lower than the vertical outerplanar of doorframe, also has the pick-proof performance, and this structure is the Three-bearing pick-proof; 3, has the double seal effect.

(4) description of drawings

Fig. 1 is the anti-schematic cross-section of forcing open the door of Three-bearing.

(5) specific embodiment

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

With reference to Fig. 1, a kind of Three-bearing is anti-forces open the door, comprise door leaf 1, left-hand door frame 2 and right doorframe 3, described door leaf 1 one sides are installed on the right doorframe 3 by hinge, the right pick-proof limit 4 of door leaf one side cooperates with the pick-proof limit 5 of right doorframe 3, the left pick-proof limit 6 of door leaf opposite side cooperates with the pick-proof limit 7 of left-hand door frame, the left pick-

proof limit

6 and 4 balanced configurations of right pick-proof limit of described door leaf, from outdoors in door, the right pick-proof limit 4 of described door leaf is provided with first step 8 successively, second step 9, the door leaf width at first step 8 places is bigger than the door leaf width at second step 9 places, and described first step 8 is " T " font, and described second step 9 is the inclined-plane dihedral.

The angle of slope of described chamfered angle is 45 °～60 °, for example can adopt 45 °, 50 °, 55 ° or 60 ° etc.The outerplanar of described door leaf is lower than the outerplanar of doorframe.

At closing time, door leaf 1 contacts earlier with the second step 9 of doorframe, and first step 8 contacts again, and the vertical outerplanar of adding whole door leaf is lower than the vertical outerplanar of doorframe, and pry is difficult to operation, thereby reaches dual pick-proof, the effect of double seal.

Claims
