AI Technical Summary

Problems solved by technology

Their structure is basically a lever structure, and devices need to be installed on the lock tongue to drive the lever to move, which increases the movement resistance of the lock tongue, causes many failures, and reduces the safety performance of the system

Embodiment 1

[0019] This is an embodiment of "many locks for one". figure 1 , figure 2 , image 3 , Figure 4 All are the accompanying drawings of this embodiment, and the core content is mainly shown in image 3 , please understand it in conjunction with each figure.

[0020] This multi-lock linkage device is made up of base plate 21 , lockset 22 , pushing slide plate 23 , control mechanism connecting rod 24 and insertion limiting device 100 . The core device is an insertion restriction device 100, which is composed of a socket 1, a plug 3, an insertion rod 11 and a push rod 12. There is a sliding cavity 2 in the socket 1 (referring to the middle cavity with 3 restrictors 9 on both sides), and at least one plugging object 3 is placed in the sliding cavity 2, here there are 3 plugging objects, and the plugging object 3 is in the Sliding in the sliding chamber 2, on one side of the normal direction of the plug sliding direction, the head 17 of at least two insertion rods 11 is inserte...

Embodiment 2

[0024] This is an embodiment of "Multiple Locks 2". Figure 5 , Image 6 , Figure 7 , are all accompanying drawings of this embodiment, and the content of the invention is mainly shown in Image 6 , please understand it in conjunction with each figure.

[0025] The difference from implementation 1 is: 1. After subtracting the total length T of the plug from the length Q of the sliding cavity, the remaining gap F can allow the width R of two insertion rods to be inserted, that is, F=2R. 2. Since it is difficult to insert the insertion rod vertically to the sliding chamber in a straight line as in implementation 1, the insertion rod will swing at a small angle when inserted, so let the insertion rod 14 (see Image 6 ) the rear part is sleeved on the pillar 16 of the push rod through the circular hole 15, and can swing around the pillar 16 axis. The insertion rod 14 here is different from the shape of the insertion rod 11 in the implementation 1, and its right side is that t...

Embodiment 3

[0030] See Figure 8 In the figure, two "choose one from two" devices 200, 201 are used to form a composite device. In the figure, M1 and M2 are spare locks, and M3, M4, and M5 are locks used for normal opening operations. Here, M3, M4, and M5 use ordinary disc-type mechanical combination locks, which can also be used in the aforementioned embodiments. . Under normal circumstances, only if M3, M4, and M5 are all opened, the door latch can be opened. Under abnormal circumstances, as long as any one of the spare locks M1 and M2 is opened, the door bolt can be opened. Different from implementation 1 and 2, M3, M4 and M5 cannot be used as spare locks, and M1 and M2 have the highest authority.

Abstract

The invention relates to a novel multi-lock linkage device, aiming at overcoming the defects that the lever-type multi-lock linkage device is inflexible. The novel multi-lock linkage device comprises a bottom plate, locks, a pushing sliding plate, a control mechanism connecting rod and an inserting limiting device. The inserting limiting device comprises a socket, filling material, inserting rods and a pushing rod; the socket is internally provided with a sliding cavity in which at least one filling material is filled; and the filling material slides in the sliding cavity; and the heads of at least two inserting rods are inserted in the socket to contact the filling material on one side of the normal line in the sliding direction of the filling material. The novel multi-lock linkage device is mainly used for the multi-lock control system of the treasury door and the safe case and can be also applied to other aspects. The novel multi-lock linkage device has the advantages that the locks can be a plurality of box-type code locks, electronic locks, fingerprint locks, electrical locks, common disc-type mechanical code locks and the like, and one or two of the locks can be used as the standby lock(s) under the premise that the tongues of the locks resist no additional force and are very flexible.

Description

technical field [0001] The present invention is a fully mechanical structure multi-lock interlocking device used on vault doors and safes, the core part of which is a fully mechanical structure insertion limiting device. Background technique [0002] There are generally multiple locks installed on the doors of important equipment such as vault doors and safes, including cassette locks, electronic locks, fingerprint locks, electric locks, etc. Under normal circumstances, only any one can be closed as a backup lock, and the other locks must be opened to open the latch. If one lock is faulty, a spare lock will be used, which is called "multiple locks for one". If there are 4 locks installed, any 3 locks should be opened normally, which is also called "4 choose 3". There are many such devices with existing mechanical structures, such as Chinese patent "200720200956 special multi-lock linkage and automatic locking and code washing control system for vault doors", "200620008848.X...
