Specific embodiment
Embodiment 1
As shown in Fig. 1,2,4, a kind of antitheft fastening door bolt of clamshell doors, including door bolt hole 1, door bolt plate 2；Door bolt hole 1 is one
Rectangular box 11, rectangular box 11 is interior to be equipped with guide rail card slot 12；It is provided with pin cylinder 21 on door bolt plate 2, is equipped with conduct in pin cylinder 21
The rack gear 22 of pin rod, the length of rack gear 22 are longer than pin cylinder 21, and the part that rack gear 22 is located in pin cylinder 21 does not set tooth, on rack gear 22
Equipped with limit guide rail 26, door bolt plate 2 be equipped with 22 meshed gears 23 of rack gear, gear 23 by shaft be mounted on pin cylinder 21 into
On the door bolt plate 2 for selling end, 23 top of gear connects a folding rocking bar 24, by pivots rocker 24 with 23 precession of moving gear, into
And with carry-over bar 22 along 21 length direction of pin cylinder to 1 end motion of door bolt hole, until insertion door bolt hole 1 completes to lock, on door bolt plate 2
Locking structure 25 equipped with locking rack gear 22.
One section of limit guide rail 26 is set on rack gear 22, when rack gear 22 sells introduction pin hole 1, limit guide rail 26 and door bolt hole 1
Interior guide rail card slot 12, which cooperates, plays the effect of limit fastening to rack gear 22, can make between rack gear 22 and door bolt hole 1
What is connected is closer.
Limit guide rail 26 is arranged when on rack gear 22, can also reserve a distance close to the one end in door bolt hole 1, convenient
The pin introduction pin hole 1 of rack gear 22.
Guide rail card slot 12 and limit guide rail 26 can be correspondingly arranged at the corresponding position in door bolt hole 1 and door bolt plate 2, such as side
