Abstract
The utility model relates to an anti-theft door, particularly an anti-theft door with a lateral bolt, which solves the problem of the locking reinforcement of sides and comprises a door leaf, a door frame, a hinge, a side lock, a lock tongue of the side lock, a middle lock and an intermediate gear box of the middle lock; an intermediate gear and two gear racks which are driven by the intermediate gear and have opposite directions and symmetrical positions are arranged in the intermediate gear box; the gear racks are connected with a connecting rod, an upper latch and a lower latch. The utility model is characterized in that a transmission mechanism which is used for driving a side latch to move from right and left is arranged on the connecting rod. The utility model is used for building construction.
Description
The utility model relates to anti-forcing open the door, and refers in particular to a kind of anti-forcing open the door with side door bolt.
Existing the anti-of multiple structural shape forced open the door, wherein, anti-the forcing open the door of multiple spot locking, door leaf is made by double-layer plate, door leaf is provided with limit lock and middle lock on an empty stomach, and the limit lock inserts doorframe by the dead bolt of general lockset, and middle lock drives idler gear and by two tooth bars that direction is opposite, the position is symmetrical of idler gear drive, tooth bar drives upper and lower bolt by connecting rod, constitutes door leaf locking point up and down; Anti-the forcing open the door of this multiple spot locking be 3 lockings of upper and lower bolt and limit lock substantially, and limit lock dead bolt strength is very weak, and the offender might promptly pry open door from the door limit from this weak link.
The purpose of this utility model just provides a kind ofly strengthens its side to overcome limit lock weak link, promptly increases the multiple spot locking pick-proof door of side locking point, also promptly has the anti-of lateral bolt structure and forces open the door.
The purpose of this utility model is achieved in that having the anti-of lateral bolt structure forces open the door, it comprises door leaf, doorframe, hinge, limit lock and dead bolt thereof, middle lock and intermediate gear box thereof, idler gear is arranged and by the tooth bar that two directions are opposite, the position is symmetrical of its transmission in the intermediate gear box; Tooth bar connects connecting rod and upper and lower bolt thereof; It is characterized in that: be provided with the transmission mechanism that drives side door bolt left and right displacement in this connecting rod.
Several locking points can be opened or latch to above-mentioned design simultaneously by middle lock; Utilize side door bolt to increase the locking point of side, reached and overcome the good result that this weak link is locked on the limit.
Below by drawings and Examples the utility model is described further again.
Fig. 1 is in the organigram that locking state is had an X-rayed its internal construction for the utility model;
As shown in the figure: the utility model comprises: doorframe 1, door leaf 2, limit lock 3 and dead bolt 4 thereof, intermediate gear box 5 and idler gear 6, two tooth bars 7,7 ', tooth bar 7 connects connecting rod 18 and goes up bolt 15, and feature of the present utility model is: connecting rod 18 is provided with the transmission mechanism 21 that drives side door bolt 20 or 20 ' left and right displacement; This transmission mechanism is made up of cam box 8, driver plate 9,11 and disk 14, and cam box 8 central authorities are installed with jackshaft 10; Driver plate 9 links to each other with connecting rod 18, which is provided with shifting shaft 13 and long slot bore 22, and links to each other with last bolt 15; Disk 14 central authorities are provided with round tube hole 23 and are arranged with two short slotted eyes 24,25 along the center of circle, and are provided with shifting shaft 12 in disk 14 upper limbs one side; Driver plate 11 1 ends connect side door bolt 20, and end is provided with slotted eye 26 and notch 27 in addition; Put driver plate 9, put disk 14, put driver plate 11 by long slot bore 22 in regular turn on the jackshaft 10 of cam box 8 by slotted eye 26 by round tube hole 23; Be that disk 14 is positioned on the driver plate 9, its short slotted eye 24 is enclosed within again on the shifting shaft 13 of driver plate 11; Driver plate 11 is positioned at again on the disk 14, and its notch 27 is enclosed within again on the shifting shaft 12 of disk 14.
Wherein, also can establish another set of transmission mechanism with transmission mechanism 21 same configuration on the connecting rod that tooth bar 7 ' connects to drive side door bolt 20 '.Wherein, on hinge 17, also can adopt the existing string pin 16 that drives by hinge 17.String pin 16 is fixed on the door leaf 2, and fashionable with doorframe 1 pass when door leaf 2, string pin 16 can carry and insert doorframe 1, plays the locking point effect.
