Description

One block plate punch forming pick-proof every frame

Affiliated technical field:

The utility model relates to a kind of pick-proof every frame.

Background technology:

Multiple pick-proof every frame of Xiao Shouing in the market, generally all be to adopt upper ledge, lower frame, lockhole frame, hinge frame four frame Combination Welding form, its weak point is that not only processing technology is made complicated, and many places exist solder joint, impression undesirable, pick-proof is pressed and firmly intensity is also bad, makes troubles for production, installation, maintenance.

Summary of the invention:

For solving the deficiency of above sash structure, the purpose of this utility model provides a kind of whole doorframe that need not to weld, and solved the processing technology complexity effectively, and external form is regular, purpose easy to install and use.

The utility model structure design is achieved in that the anti-integral door frame of forcing open the door is a block plate punch forming, become rectangular configuration, the frame junction does not have weld seam, the doorframe height is 1854mm～2150mm, width is 791mm～1100mm, four jiaos are little circular-arc in the doorframe, and the ladder mouth is all arranged all around, and whole doorframe is an integral body.

Advantage of the present utility model: the processing technology novelty, no welding line structure, smooth, precision is high, aesthetic in appearance, the pick-proof performance is good, has very big promotional value.

Description of drawings: Fig. 1 is block plate punch forming pick-proof every frame external form figure; Fig. 2 is block plate punch forming pick-proof every frame orthographic drawing; Fig. 3 is the figure of block plate punch forming pick-proof every frame lateral projection; Fig. 4 is the lower frame section amplification figure; Fig. 5 is the side frame section amplification figure.

The specific embodiment:

This anti-doorframe of forcing open the door as shown in drawings.1 is pick-proof every frame, 2 is pick-proof every frame ladder mouth, guarantee to closely cooperate between door and the doorframe, Fig. 2 is an orthographic drawing, two side sections are the approximate circle arcuation, and the inboard has partly seals, and Fig. 3 is same spline structure for the figure of lateral projection, doorframe both sides and top, the bottom is the right angle stairstepping, and this doorframe height is 791mm for the 1854mm width.

Claims (2)

1, a kind of pick-proof every frame is characterized in that this doorframe (1) is a block plate moulding, becomes square type structure, and the frame junction does not have weld seam, and four jiaos are little circular-arc in the doorframe, and the ladder mouth is all arranged all around, and (2) whole doorframe is an integral body.

2, by the described doorframe of claim 1, it is characterized in that the doorframe height is 1854mm～2150mm, width is 791mm～1100mm.
