Abstract
The utility model discloses a three-way five tongue automatic anti-theft door lock with a cross core, comprising a lock shell, a cover plate, a handle member, an upper and a lower connecting rods, a lock head, a handle shell, etc. The utility model is characterized in that the inner part of the lock shell of the three-way five tongue automatic anti-theft door lock with a cross core is provided with an automatic locking mechanism which is composed of a tongue plate member, a lock head fixing plate member and a cam member. The automatic locking mechanism can force the tongue plate to be locked by the cam member, so the static pressure in an axial direction of the main lock tongue (bolt) is greatly increased, and anti-theft safety performance of the anti-theft door lock is reinforced.
Description
The utility model relates to a kind of lockset, particularly a kind of in the horizontal direction, vertical direction can simultaneously sealed automatic anti-theft door lock.
At present, the key operated Mechanical theft-proof door lock of selling on the market of various usefulness, though it is of a great variety, but after testing, the axial static pressure of the main dead bolt (bolt) of most Mechanical theft-proof door locks does not all reach the requirement that is equal to or greater than 9800N of " People's Republic of China's public security Safety Industry standard " regulation, thereby has reduced the anti-theft security performance of Mechanical theft-proof door lock widely.
Problem in view of above-mentioned existence, the purpose of this utility model provides a kind of simple and reasonable for structure, and what the axial static pressure of the main dead bolt (bolt) of easy to use, safe-guard door lock met " People's Republic of China's public security Safety Industry standard " regulation is equal to or greater than 9800N cross core three-dimensional five tongue automatic anti-theft door locks that require, that the anti-theft security performance is good.
For achieving the above object, the utility model has been taked following technical scheme:
The utility model has added automatic locking mechanism in lock housing, automatic locking mechanism is made of hyoplastron parts, tapered end fixed plate part and cam part; Automatic locking mechanism can pass through tapered end fixed plate part, cam part positive lock hyoplastron, thereby can improve the axial static pressure of main dead bolt (bolt) greatly.
Through the utility model after the above-mentioned design, rational in infrastructure, safe in utilization, reliable, the axial static pressure of its main dead bolt (bolt) has not only reached the requirement that is equal to or greater than 9800N of " People's Republic of China's public security Safety Industry standard " regulation fully, and has improved the anti-theft security performance of safe-guard door lock greatly.
Specific embodiments of the present utility model is as shown in drawings:

Below in conjunction with the embodiment that provides in the accompanying drawing, concrete structure of the present utility model is further specified:
Cross core three-dimensional five tongue automatic anti-theft door locks include lock housing 1, cover plate 3, handle parts 2, go up parts such as connecting rod 6, lower link 7, tapered end 4, handle shell 5.In lock housing 1, be provided with an automatic locking mechanism, automatic locking mechanism is made of hyoplastron parts 8, tapered end fixed plate part 9 and cam part 10; Hyoplastron parts 8 contain the hyoplastron that is portal structures 11 of a right angle type, and the inboard of the hyoplastron of portal structures is provided with tooth bar 22; Be on the vertical hyoplastron edge 12, be provided with two round tongues 13 and a touching column circle tongue 14; On the hyoplastron 11 that is portal structures, be provided with latch hook 19; The round tongue 13, the touching column circle tongue 14 that are arranged on the hyoplastron edge 12 that is vertical are hollow-core construction; In touching column circle tongue 14, be provided with touching column 15 and spring 16; Be arranged at an end of the latch hook 19 that is on the portal structures hyoplastron 11, be provided with an inclined-plane 18; The other end is provided with a hook 21, and the back of latch hook is provided with return spring 20; The end that latch hook 19 is provided with ramp structure contacts with transferring power with touching column circle tongue axle 17; Be arranged at the hook 21 and the positioner that is arranged at the column 23 formation circle tongues in the lock housing of the other end.
Tapered end fixed part 9 is made of tapered end 4, tapered end location-plate 24, circlip 25 and corner angle 26; Tapered end 4 is fixed on the tapered end location-plate 24.On tapered end location-plate 24, be provided with two supporting legs 27, supporting leg has been provided with spring 28, and supporting leg 27 is sleeved in the round tongue 13 that is hollow.
Cam part is made of lobe plate 29, camshaft 30, gear 32, on lobe plate 29, is provided with post 31; Lobe plate 29 is sleeved in the groove of gear 32, and the post 31 on the actuating cam plate 29 can make lobe plate 29 and gear 32 rotate synchronously; 30 of camshafts are connected with handle shell 5, constitute manual door lock opening mechanism.
Be arranged on the cam part gear 32 in the horizontal direction, be meshed with tooth bar 22 on the hyoplastron inboard that is portal structures on the hyoplastron parts, constitute the bolt locking mechanism on the security door horizontal direction; In vertical direction, be meshed, constitute the keeper locking mechanism on the security door vertical direction with tooth bar 32 on being arranged at connecting rod 6, lower link 7.
Working method of the present utility model is achieved like this:
During with key operated security door, key is inserted in the tapered end, key, the corner angle 26 that drive on the tapered end rotate, and corner angle are stirred the post 30 on the lobe plate 29, and lobe plate 29 and gear 32 are rotated synchronously; When gear 32 rotated, the tooth bar 22 that drives in the horizontal direction on the hyoplastron inboard that is portal structures on the hyoplastron parts inwardly moved, and opens the bolt locking mechanism on the security door horizontal direction; And in vertical direction, then drive the tooth bar 33 on the upper and lower connecting rod, and make all inwardly motions of upper and lower connecting rod, open the keeper on the vertical direction, can open security door like this.
When indoor unlatching security door, rotatable handle shell 5, because handle shell 5 is connected with camshaft on the lobe plate 29, so rotate the handle shell, promptly be to have rotated lobe plate, thereby can rotate together by driven gear 32, like this, can drive tooth bar 22 on the hyoplastron and the tooth bar 33 on the upper and lower connecting rod, open dead bolt on the horizontal direction and the keeper on the vertical direction, open security door.
At closing time, can promote security door gently, when the touching column 15 on the circle of the touching column on the hyoplastron parts tongue 14 is collided by doorframe, be arranged at the touching column circle tongue axle 17 in the touching column circle tongue 14, promote the inclined-plane 18 on the latch hook 19, make the hook 21 on latch hook 19 other ends break away from column 23, under the effect of the spring 16 in being arranged at round tongue 13, make hyoplastron that is portal structures and circle proal together while of tongue on the hyoplastron parts, driven gear rotates, and drives upper and lower connecting rod and outwards moves; Like this, in the horizontal direction with vertical direction on three five tongues close simultaneously, thereby just realized that also security door cuts out.
Because the utility model is in automatic locking mechanism, be provided with hyoplastron parts, tapered end fixed plate part and cam part, the return spring 20 that is arranged at the latch hook back when security door cuts out makes the hook 21 and column 23 auto-closings on the latch hook, plays the effect of insurance.At this moment, if no key operated door lock cuts off and may not open security door.
