Abstract

The utility model discloses a high-intensity anti-prizing door with hidden hems. The periphery of an outer plate of a door body is provided with an anti-prizing hem which is larger than an inner plate of the door body, an outer rim of the anti-prizing hem folds back a short hem inwards, and a groove shape is formed. The inner plate of the door body is inlaid in the outer plate which is connected with the inner plate through rivet welding, and sealing rubber strips which are inlaid in grooves of the outer plate of the door body can ward connecting gaps of the inner plate and the outer plate. The anti-prizing hem structure of the outer plate of the door body can cover gaps between the door body and a doorframe, a prizing tool can be prevented from inserting into the gaps, the burglar-proof door can be not prized, and the burglar-proof degree of the burglar-proof door can be enhanced. The structure of the sealing rubber strips can ward the connecting gaps of the inner and the outer plates of the door body so that the connecting gaps are not revealed, the door is more beautiful, and meanwhile, the sealing rubber strips play the damping effect.

Description

High-strength latent frontier defense is forced open the door

Technical field:

The utility model is to the improvement of existing security door, has invented a kind of high-strength latent frontier defense and has forced open the door, and belongs to pick-proof gate technique field.

Background technology:

Existing security door does not generally have the anti-limit structure of forcing open the door, and excesssive gap between doorframe and the door body is easy to put in and does not prize instrument, reduced the safety of security door, and exhume outside at the inside and outside door-plate solder joint that adds door body in man-hour, cause a surface planeness relatively poor, influenced the attractive in appearance of door.

Summary of the invention:

The utility model provides a kind of high-strength latent frontier defense to force open the door, and has latent type pick-proof limit, has overcome common security door excesssive gap, easily not Qiao shortcoming.

Technical pattern of the present utility model is as follows: be provided with pick-proof limit greater than door body inner panel at the periphery of the external plate of door, inside inflection one minor face in the outer on pick-proof limit, form the groove shape, door body inner panel is embedded in the outside plate, connect by rivet welding, sealing joint strip is embedded in the groove of the external plate of door, the connection slit of inner and outer plates can be blocked.

Good effect of the present utility model is: the external plate pick-proof of door limit structure can cover in the gap between the Men Tiyu doorframe, has prevented that the sled instrument does not inject in the gap, has guaranteed that security door is not prized, and has improved the antitheft degree of security door; The sealing joint strip structure can be blocked the connection slit of the inside and outside plate of door body and not expose, and makes it more attractive in appearance, has played damping effect simultaneously.

The specific embodiment:

According to shown in Figure 1, be provided with pick-proof limit 1 at the periphery of the external plate 2 of door greater than door body inner panel 4, inside inflection one minor face in the outer on pick-proof limit 1, form groove shape (referring to Fig. 2), door body inner panel 4 is embedded in the outside plate 2, and the Men Tizhong device has filler 3, puts 7 fixedly connected by rivet welding, sealing joint strip 6 is embedded in the groove of the external plate 2 of door, (see figure 3) can be blocked in the connection slit of inside and outside plate.The utility model can not prized the covering of the gap rigidity between the Men Tiyu doorframe instrument and can't be inserted greater than the pick-proof limit of door body inner panel in use, has guaranteed that the door body is not pried open.

Claims

1, a kind of high-strength latent frontier defense is forced open the door, it is characterized in that: the periphery of the external plate of door is provided with the pick-proof limit greater than door body inner panel, inside inflection one minor face in the outer on pick-proof limit, form the groove shape, door body inner panel is embedded in the outside plate, connect by rivet welding, sealing joint strip is embedded in the groove of the external plate of door, the connection slit of inner and outer plates can be blocked.
