Abstract
The invention discloses a breakage-proof relocking device for a vault door. The vault door comprises a door plate, a sliding bolt plate and a door plate fixing seat, the sliding bolt plate is slidably arranged below the door plate fixing seat, and a circular hole is arranged on the sliding bolt plate. The relocking device comprises a constant-load nylon ring and a bolt head, the upper end of the constant-load nylon ring is fixed into the door plate, the bolt head is connected with the lower end of the constant-load nylon ring and is positioned right above the circular hole of the sliding bolt plate, and a pre-tightening spring is arranged above the bolt head. The breakage-proof relocking device for the vault door is simple in structure, and can effectively guard against theft as the vault door can be relocked under the action of external force such as thump or high temperature.
Description
Technical field
The present invention relates to the vandal-proof heavy locking device of a kind of national treasury door, be specifically related to a kind of device of when destroying the national treasury door heavily being locked in external force (comprising bang and high temperature).
Background technology
The national treasury door is a kind of special security door, is the indispensable part of bank vault, the safety that it is antitheft, fire prevention, the anti-height of ruining performance directly have influence on bank vault.But when it suffers outside destroy, can't in time protect.
Summary of the invention
To the objective of the invention is the defective that exists in the prior art in order solving, a kind of device that can heavily lock the national treasury door when outside destroy to be provided.
In order to achieve the above object, the invention provides the vandal-proof heavy locking device of a kind of national treasury door, wherein the national treasury door comprises door-plate, sliding latch plate and door-plate holder, and the sliding latch plate slidably is located at door-plate holder below, and the sliding latch plate is provided with circular hole; The heavy locking device of the present invention comprises decides lotus nylon ring and door bolt head; Deciding lotus nylon ring upper end is fixed in the door-plate; Door bolt head with decide lotus nylon ring lower end and link to each other, and be positioned at directly over the circular hole of sliding latch plate; Door bolt head top is provided with preloading spring.
Above-mentioned heavy locking device also comprises wire rope and Ding He steady pin.It is a plurality of deciding the lotus steady pin, is fixed in the door-plate; Wire rope is located in the door-plate, and hangs over by the stage casing and to decide to form at least one broken line on the lotus steady pin; Wire rope one end is fixed on to be decided on the lotus steady pin, and the other end is fixed on decides lotus nylon ring upper end; Deciding the lotus nylon ring is fixed in the door-plate by wire rope.
Wherein, wire rope preferably is located at 1/2nd places (being in the middle of the door-plate) of door-plate thickness; And the wire rope shape preferably is netted layout; The netted node place of wire rope all is enclosed within and decides on the lotus steady pin, by deciding lotus steady pin tense wire rope.Decide the lotus steady pin and be provided with safety groove; Steel wire loop is in the described safety groove of deciding the lotus steady pin.The safety groove of deciding the lotus steady pin is preferably the open circles annular groove.
The present invention has the following advantages compared to existing technology: utilize and decide the fixing door bolt of lotus nylon ring head, when being subjected to the external force bang, decide the fracture of lotus nylon ring, or when outside high temperature, decide the lotus nylon ring and be out of shape, all make below door bolt head fall in the circular hole of sliding latch plate in the screen resilience effect of preloading spring, reach the heavily function of lock.Wire rope when external force is thumped, is decided the safety groove fracture of lotus steady pin by deciding the tension of lotus steady pin simultaneously, and wire rope gets loose, and the same door bolt head that makes falls in the circular hole of sliding latch plate, reaches the effect of double insurance.The vandal-proof heavy locking device of national treasury door of the present invention is simple in structure, under the external force effect of bang or high temperature, all can carry out national treasury Men Chongsuo, can be effectively antitheft.
Description of drawings
Fig. 1 is the structural representation of the heavy locking device of the present invention;
Fig. 2 is the structural representation of deciding the lotus steady pin among Fig. 1;
Fig. 3 is the partial enlarged drawing at A place among Fig. 1.
Among the figure, 1-decides the lotus steady pin, the 11-safety groove, and the 2-wire rope, the netted node of 21-, 3-decides the lotus nylon ring, the 4-preloading spring, 5-fastens head with a bolt or latch, 6-door-plate holder, 7-sliding latch plate, 71-circular hole.
The specific embodiment
Below in conjunction with accompanying drawing the heavy locking device of the present invention is elaborated.
As shown in Figure 1, the heavy locking device of the present invention comprise wire rope 2, decide lotus steady pin 1, decide lotus nylon ring 3, preloading spring 4 and door bolt 5.Wire rope 2 is mesh cloth and places door-plate thickness 1/2nd places, and each netted node 21 place is equipped with one and decides lotus steady pin 1(and only need form a broken line, can reach the loosening purpose of wire rope when deciding the fracture of lotus steady pin; Adopting netted layout is in order to make the distribution crypto set more of wire rope, to make any position of external force bang national treasury door all can make wire rope loosening, being preferred plan), by deciding lotus steady pin 1 tense wire rope 2.One end ring of wire rope 2 is enclosed within one to be decided on the lotus steady pin 1, thereby realizes that end points fixes, the other end with decide lotus nylon ring 3 upper ends and link to each other.The lower end of deciding lotus nylon ring 3 and cylindric door bolt 5 links to each other.Door bolt 5 is positioned at directly over the circular hole 71 of sliding latch plate 7.Door bolt 5 top are provided with preloading spring 4, and the screen resilience of preloading spring 4 is owing to decide the tightening force counteracting of lotus nylon ring 3, and door bolt 5 tension are positioned at the top of circular hole 71 when making normal condition, as shown in Figure 3.
In conjunction with Fig. 2, decide lotus steady pin 1 and be provided with safety groove 11.Safety groove 11 is annular groove, and centre-drilling hole forms the open circles annular groove.The thickness of safety groove 11 and fineness are by default limit external impact force (as 2000N), again according to data operation and the design of limit pull-off force.Wire rope 2 is placed in the safety groove 11 of deciding lotus steady pin 1.
When external impact force value of reaching capacity of being subjected to, decide safety groove 11 fractures of lotus steady pin 1, wire rope 2 gets loose, the lotus nylon ring 3 of deciding that one end connects gets loose, or make that directly deciding lotus nylon ring 3 ruptures, the screen resilience of preloading spring 4 makes door bolt 5 fall in the circular hole 71 of slid underneath door bolt plate 7, thereby stuck sliding latch plate 7 reaches the purpose of locking.When the external flame high temperature value of overstepping the extreme limit (as 100 degree), decide lotus nylon ring 3 distortion, the screen resilience of preloading spring 4 overcomes the tightening force of deciding lotus nylon ring 3, makes door bolt 5 fall in the circular hole 71 of slid underneath door bolt plate 7, same stuck sliding latch plate 7 reaches the purpose of locking.
