A pulling gate adopting the structure of the utility model can prevent thieves from prying a gate between the movable railing and a gatepost and between a movable railing guide pillar and the gatepost and makes the pulling gate safe.
Description
The utility model belongs to building doors and windows, and especially pull gate is made the field.
At present draw the pull gate of forming by doorframe column, doorframe locked groove and the movable grid that constitute by the many door bars that are movably hinged mutually that are supported on the roller, the fixed end of its portable fence connects firmly on doorframe column, though the door bar and the column of fence connect firmly riveted joint, but there is defective on the structure (shown in A portion among Fig. 2), the burglar can be between door bar and column the insertion instrument, destroy connecting of door bar and doorframe column; Also can adopt same gimmick destructive activity fence to connect with the effective of doorframe locked groove at the portable fence other end (as the B portion among Fig. 2), final, the destruction of will operating a switch reaches the purpose of committing theft.
In view of the above shortcoming of prior art, the purpose of this utility model is a kind of pull gate with pick-proof structure of design, transforms fence and doorframe draw bail, prevents that the burglar from adopting method as above to destroy pull gate.
The purpose of this utility model is to realize by following means.
Mainly by doorframe column, doorframe locked groove and be supported on the pull gate that the portable fence that is made of the many door bars that are movably hinged mutually on the roller etc. is formed, roller places on the base track, the fixed end and the door pillar of portable fence connect firmly, the other end guide pillar of portable fence can snap in the doorframe locked groove sealed by lock bolt and doorframe on it, and the section bar of doorframe column has the termination door bar coating that one " " shape cornerite will connect firmly movable grid thereon; But and has the protuberance in gap between shutoff doorframe locked groove and guide pillar on the other end guide pillar of the portable fence of doorframe locked groove clamping.
After having adopted design as above,, improved the safe effect of pull gate because the shutoff of " " shape of column section bar structure and guide pillar protuberance makes the burglar insert tools used in crime such as screwdriver at A, B place again, thereby reached thief-proof purpose.
Description of drawings is as follows.
Fig. 1 is the local structure structure chart of prior art pull gate.
