Problems solved by technology

[0003] This auxiliary lock mechanism also has the following defects: 1. A straight bolt push plate is adopted, so for the stability of the work, the straight bolt holder cannot be too wide, so that the distance between the two straight bolts installed on the straight bolt holder cannot be separated. Too far, so that the two straight bolts can only be set next to each other, and the hook bolts are set aside
2. In this technical solution, the hook bolt is driven by a dial pin, but the angle that the precessor can drive the hook bolt to rotate in one stroke is limited, and the hook bolt cannot form a fully closed locking state.
However, in the secondary lock disclosed by CN201103290Y, the precessor is not as close to the panel as the slide bolt in CN202467387U, but close to the back plate position of the secondary lock housing
Therefore, the annular deadbolt in CN202467387U cannot be directly combined into the auxiliary lock disclosed in CN201103290Y

Embodiment 1

[0038] figure 1The schematic diagram of the structure shown in the lock-out state is a preferred implementation of this embodiment. The secondary lock of this embodiment includes a secondary lock housing 1 and at least two bolt mechanisms and reversing swing members arranged inside the secondary lock housing 1. 31 . A ring knuckle 41 , a gear 42 and an actuator 43 . The secondary lock housing 1 has a cover plate 11 ( figure 1 Not shown in , its structure is as image 3 shown) and bottom plate 12, and the panel 13, back plate 14 and side wall plate 15 that are connected between the cover plate 11 and the bottom plate 12, that is, the secondary lock housing 1 is a box body, and its internal space is used for accommodating and Install the above-mentioned bolt mechanism and other components.

[0039] There are two above-mentioned deadbolt mechanisms in the auxiliary lock of this embodiment, wherein the two deadbolt mechanisms are arranged along the length direction of the panel...

Embodiment 2

[0053] This embodiment is a deformation on the basis of Embodiment 1, and it is different from Embodiment 1 in that:

[0054] In this embodiment, the second toggling mechanism 33 includes a second toggle pin 331 fixed on the reversing swing member 31 perpendicular to the bottom plate 12 and an edge lock formed on the actuating member 43 . The second shifting groove 332 extending in the direction, the second shifting groove 332 is suitable for the insertion of the second shifting pin 331, and makes the second shifting pin 331 move parallel to the locking direction relative to the second shifting groove 332 The degree of freedom is equivalent to exchanging the formation positions of the groove and the pin in the second toggle mechanism 33 . Similarly, the first toggle mechanism 32 may also include a first toggle pin 321 fixed on the support frame 22 perpendicular to the bottom plate 12 and a pin 321 formed on the reversing swing member 31 along the direction perpendicular to the...

Abstract

The invention discloses an auxiliary lock with a hook bolt. On one hand, each spring bolt mechanism is independently and correspondingly provided with a reversing swinging piece, an actuation piece capable of synchronously driving the multiple reversing swinging pieces is matched, the two spring bolt mechanisms can be spaced at a long distance to be independently arranged, and therefore the safety performance of the two spring bolt mechanisms can be completely achieved; and on the other hand, based on the fact that the two spring bolt mechanisms are spaced at the long distance, the annular hook bolt can be arranged between the two spring bolt mechanisms and driven through a linked gear in an engaged manner. According to the actual use requirement, a complete lock-in or lock-out stroke can be finished by the annular hook bolt according to the transmission ratio of a driving gear on the side and the gear so that the auxiliary lock with the hook bolt in the embodiment can overcome the technical defects that multiple straight spring bolts existing in an existing auxiliary lock only can achieve the effect of one straight spring bolt, the spring bolts cannot be completely closed, and the protection performance is poor; and the structure is more compact.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a secondary lock with a knuckle. Background technique [0002] For large safety doors or safety doors with high security level requirements, it is usually necessary to set a secondary lock linked with the door lock on the side of the door leaf on the same side as the ordinary door lock. In order to further improve the safety performance of the secondary lock, some additional safety mechanisms are provided on the secondary lock in the prior art, such as a secondary lock disclosed in Chinese patent document CN201103290Y, which includes a secondary lock housing and a straight bolt arranged in the secondary lock housing. The support body and the straight bolt fixedly connected with the straight bolt support body, the straight bolt push plate with the middle part hinged with the secondary lock housing, one end hinged with the straight bolt support body, and the other end of the straight...
