Problems solved by technology

Although this bolt linkage type electronic mortise lock solves the problem that the square bolt and the sharp bolt are linked through movable parts to realize convenient one-time unlocking or closing, but this kind of lock still has a relatively complicated structure. When the square bolt is not inserted When installing the door frame, it still cannot prevent the problem that someone with ulterior motives will use a hard sheet (such as an old-fashioned ID card) to insert it from the sharp pin tongue.

Embodiment 1

[0028] See figure 1 , figure 1 What is disclosed is a locking tongue linkage mechanism, which includes a first locking tongue 1 (equivalent to a pointed locking tongue) and a second locking tongue 2 (equivalent to a square locking tongue), a first locking tongue rotating shaft 3, a first connecting rod 4 , the first movable rotating shaft 5, the second connecting rod 6, the fixed shaft 7, the third connecting rod 8, the second movable rotating shaft 9, the fourth connecting rod 10 and the second dead bolt rotating shaft 11, the first dead bolt rotating shaft 3 It is located at the tail end of the first deadbolt 1 and is movably connected with one end of the first connecting rod 4 (this connection method is similar to the connection method between the piston and the connecting rod in an automobile), the first The other end of the connecting rod 4 and one end of the second connecting rod 6 are twisted through the first movable rotating shaft 5 (for its three-dimensional structu...

Embodiment 2

[0031] In order to further improve the anti-theft opening performance of the deadbolt linkage mechanism, the deadbolt linkage mechanism can be further improved, such as figure 2 As shown, it is in figure 1 On the basis of the shown embodiment, the fifth connecting rod 16, the sixth connecting rod 17, the third movable rotating shaft 18 and the second fixed shaft 19 are added, and it is preferable to arrange a ring for preventing The stop member 20 that the fifth connecting rod 16 passes through. And let the fifth connecting rod 16 be located between the third connecting rod 8 and the fourth connecting rod 10, one end of the fifth connecting rod 16 and one end of the third connecting rod 8 pass through the third movable shaft 18 twisted joints, the other end of the fifth connecting rod 16 is twisted with the fourth connecting rod 10 through the second movable shaft 9, the sixth connecting rod 17 is located at the tail end of the fourth connecting rod 10, the sixth connecting ...

Embodiment 3

[0034] See image 3 , in order to achieve multilateral locking with the door frame, the present invention can also be designed to include at least one third dead bolt 24, at least one fourth dead bolt 29 ( image 3 Only draw a 3rd dead bolt 24 and a 4th dead bolt 29 in, in fact also can establish the 3rd dead bolt and the 4th dead bolt according to need), the seventh connecting rod 20, the 4th movable rotating shaft 21, The eighth connecting rod 22, the third deadbolt rotating shaft 23, the ninth connecting rod 25, the fifth movable rotating shaft 26, the tenth connecting rod 27 and the fourth dead bolt rotating shaft 28, one end of the seventh connecting rod 20 is fixed on The second connecting rod 6 and the fixed shaft 7 are sleeved on the second connecting rod sleeve 61, and the other end of the seventh connecting rod 20 is twisted with one end of the eighth connecting rod 22 through the fourth movable shaft 21. The other end of the eighth connecting rod 22 is movably conn...

Abstract

The invention discloses a spring bolt linkage mechanism. A first spring bolt revolving shaft is arranged at the tail end of a first spring bolt and is movably connected with one end of a first connection rod; the other end of the first connection rod is hinged with one end of a second connection rod; the other end of the second connection rod is sleeved on a fixed shaft; one end of a third connection rod is sleeved on the fixed shaft; a torque spring is arranged between a sleeve head of the second connection rod and a sleeve head of the third connection rod; one end of the torque spring is fixedly connected with the sleeve head of the second connection rod; the other end of the torque spring is fixedly connected with the sleeve head of the third connection rod; a returning spring is arranged on the sleeve head of the third connection rod; one end of the returning spring is fixedly connected with the fixed shaft; the other end of the returning spring is fixedly connected with the sleeve head of the third connection rod; the other end of the third connection rod is hinged with one end of a fourth connection rod; and the other end of the fourth connection rod is movably connected with a second spring bolt revolving shaft. The invention has the advantages that the spring bolt linkage mechanism has a simple structure and the lock cannot be unlocked by poking the lock with a hard sheet.

Description

technical field [0001] The invention relates to a component of an anti-theft lock, in particular to a lock tongue linkage mechanism applicable to an anti-theft lock with two lock tongues. Background technique [0002] Chinese patent document CN2546579 discloses a dead bolt linkage type electronic mortise lock, which is provided with an elastic clamping post in the middle of the upper dead bolt, and a movable part is arranged in the cavity, and the upper dead bolt, the middle dead bolt and the lower dead bolt are fixed on On the side plate of the movable part, the movable part can slide in the lower cover, and the rear end of the movable part is provided with a shift block matched with the shift fork, and a switch part is also hinged in the lower cover, and the front end of the switch part is protrudingly provided with a button which is connected with the inside of the upper lock tongue. The baffle plate matched with the elastic column, the rear end surface of the baffle plat...
