The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 7, the lock body provided by the embodiment of the invention, in particular to a dual-speed lock body, mainly comprises a blocking piece 3 besides a shell 1, a handle 6 and a main lock tongue 2. The main lock tongue 2 is arranged in the shell 1 and can stretch and retract relative to the shell 1, the handle 6 is an operation part of a person, and when the person rotates the handle 6 anticlockwise or clockwise, the main lock tongue 2 can stretch and retract relative to the shell 1; the blocking piece 3 is also arranged in the shell 1 and can stretch relative to the shell 1, when the door is opened, the blocking piece 3 stretches out of the shell 1 under the action of the spring, when the door is closed, the blocking piece 3 retracts into the shell 1 due to the blocking of the door frame, and when the blocking piece 3 stretches out of the shell 1, the blocking piece 3 blocks the main lock tongue 2, so that before the door is closed, even if a person accidentally applies force to the handle 6, the main lock tongue 2 does not stretch out, no collision occurs between the main lock tongue 2 and the door frame, the damage of the lock body and the door frame is avoided, and when the blocking piece 3 retracts into the shell 1, the blocking piece 3 does not block the main lock tongue 2, and the main lock tongue 2 can stretch into the door frame under the driving of the handle 6 to realize locking.
In order to further optimize the technical solution, in the lock body provided in this embodiment, as shown in fig. 3 to 7, the lock body further includes a transmission member 5 rotatably disposed in the housing 1, where the transmission member 5 includes: a first transmission arm 51 which is matched with the handle 6 and drives the transmission piece 5 to rotate under the drive of the handle 6; the second transmission arm 52 is connected with the main lock tongue 2 and drives the main lock tongue 2 to stretch and retract relative to the shell 1 through the rotation of the transmission piece 5; the third actuator arm 53, which cooperates with the blocking member 3 and can be blocked by the blocking member 3, is preferably a one-piece structure of the first actuator arm 51, the second actuator arm 52, and the third actuator arm 53. In this embodiment, the blocking manner of the blocking member 3 on the main lock tongue 2 and the linkage manner of the handle 6 and the main lock tongue 2 can be selected in various manners, and in order to simplify the structure and improve the mutual matching effect between the components, it is preferable to add a transmission member 5, where the transmission member 5 is essentially a lever, and is simultaneously matched with the handle 6, the main lock tongue 2 and the blocking member 3, and is rotatably disposed on the housing 1, specifically, of the three transmission arms on the transmission member 5, the first transmission arm 51 is matched with the handle 6 to realize linkage with the handle 6, the second transmission arm 52 is matched with the main lock tongue 2, and when the blocking member 3 does not play a role in blocking, the first transmission arm 51 is driven to rotate by rotating the handle 6, and then the second transmission arm 52 integrated with the first transmission arm 51 is driven to rotate, and finally, the main lock tongue 2 is driven to extend out of the housing 1 or retract into the housing 1. The third transmission arm 53 is matched with the blocking piece 3, when the blocking piece 3 is in a state of extending out of the shell 1, the blocking piece 3 can block the third transmission arm 53, so that the whole transmission piece 5 cannot rotate, personnel cannot realize the expansion and contraction of the main lock tongue 2 when exerting force on the handle 6, and the blocking piece 3 is in a door opening state when extending out of the shell 1, so that the personnel can not extend the main lock tongue 2 even touching the handle 6 at the moment, and the main lock tongue 2 and a door frame are prevented from being impacted when the door is closed.
Furthermore, the transmission element 5 may not be provided, the blocking element 3 may be pivoted to allow expansion and contraction relative to the housing 1 and directly block the main bolt 2 when it is extended, while the handle 6 is connected to the main bolt 2 by a special linkage element.
Preferably, as shown in fig. 3 to 5, the handle 6 is provided with a first shifting arm 61 and a second shifting arm 63 disposed along a radial direction of the mounting hole 62 of the handle 6, an included angle is formed between the first shifting arm 61 and the second shifting arm 63, and an end portion of the first transmission arm 51 is located in an included angle space between the first shifting arm 61 and the second shifting arm 63 and can be rotated by pushing the first shifting arm 61 and the second shifting arm 63. The arrangement of the structure can drive the first transmission arm 51 (or the whole transmission piece 5) to rotate in different directions (clockwise or anticlockwise) through different poking arms when the handle 6 rotates clockwise or anticlockwise, so that the main bolt 2 is driven to stretch under the premise that the blocking piece 3 does not play a blocking role. In addition, in this arrangement, because of the space of the included angle, the first driving arm 51 may remain stationary until the first shifting arm 61 or the second shifting arm 63 contacts, i.e. the handle 6 has a certain margin of rotation, when the blocking member 3 blocks the driving member 5, after the person applies force to the handle 6, the handle 6 can idle within a certain angle range, and the main lock tongue 2 is not driven to move, so that the operation comfort of the lock body provided in this embodiment is improved. Of course, the first driving arm 51 and the handle 6 may be coupled by a gear engagement manner, for example, a sector wheel is provided at an end of the first driving arm 51, a gear engaged with the sector wheel is provided on the handle 6, and the coupling with the main latch 2 may be achieved by such a manner that the normal operation of the blocking member 3 is not affected, but the difference between the first shifting arm 61 and the second shifting arm 63 is that, due to the engagement positioning of the gear teeth, when the blocking member 3 blocks the driving member 5 from driving, a person cannot rotate the handle 6 when applying a force to the handle 6.
In this embodiment, as shown in fig. 1 to 7, the blocking member 3 is a plate-like member, and expansion and contraction with respect to the housing 1 are achieved by reciprocal translation. In this arrangement, the blocking and avoiding of the transmission element 5 can be realized by only reserving a small translational movement space for the blocking element 3. The blocking member 3 may be a hook member, a plate member, or the like that blocks the transmission member 5 by rotation.
Specifically, as shown in fig. 6 and 7, the end of the third driving arm 53 is connected with a stopper 54, and the width of the stopper 54 is larger than that of the third driving arm 53; the blocking member 3 is provided with a through hole 31 allowing the stopper 54 to pass therethrough, and an opening 32 communicating the through hole 31 and the edge of the blocking member 3, the opening 32 allowing only the third transmission arm 53 to pass therethrough. When the blocking member 3 blocks the third driving arm 53, that is, when the blocking member 3 extends out of the housing 1, the stopper 54 connected to the end portion of the third driving arm 53 is aligned up and down with the opening 32, the stopper 54 cannot pass through the opening 32 because the width of the stopper 54 is larger than the width of the opening 32, so that the driving member 5 cannot rotate, and when the blocking member 3 is retracted into the housing 1, the through hole 31 moves to a position aligned up and down with the stopper 54, and because the stopper 54 can pass through the through hole 31 and the third driving arm 53 can pass through the opening 32, the driving member 5 can continue to rotate through the blocking member 3, the blocking member 3 releases the blocking of the driving member 5, and the main bolt 2 is driven to extend out of the housing 1 under the full rotation of the driving member 5.
As shown in fig. 1-5, it is further preferred that the blocking member 3 is located between the main bolt 2 and the tongue 4 of the lock body. The arrangement mode can enable the overall structure of the lock body to be more compact, so that the lock body is taken as a preferable arrangement mode.
After the lock body provided by the embodiment is installed on the door, the specific working mode is as follows:
When the door is in an open state, as shown in fig. 3, the main bolt 2 is fully contracted in the shell 1, the blocking piece 3 and the inclined bolt 4 extend out of the shell 1 under the action of springs and the like, at the moment, if the handle 6 is pressed down, the handle 6 rotates clockwise, then the second shifting arm 63 on the handle 6 is utilized to drive the first transmission arm 51 to rotate, so that the whole transmission piece 5 is driven to rotate, but because the main bolt 2 is in a contracted limit position at the moment and cannot be continuously contracted, the second transmission arm 52 connected with the main bolt 2 limits the rotation of the transmission piece 5, and therefore, the handle 6 is pressed down, so that the main bolt 2 cannot generate any state change; at this time, if the handle 6 is lifted, the handle 6 rotates reversely, and then the first shifting arm 61 on the handle 6 drives the first driving arm 51 to rotate clockwise, so as to drive the whole driving member 5 to rotate clockwise, but because the blocking member 3 is in the extending state, the stop block 54 is aligned with the opening 32, and the width of the opening 32 of the blocking member 3 is smaller than that of the stop block 54, as shown in fig. 6, the rotation of the driving member 5 is limited, the driving member 5 cannot drive the main bolt 2 to translate, and therefore, when the door is in the opening state, the lifting handle 6 does not extend the main bolt 2.
When the door is in a closed state but not locked up, as shown in fig. 4, if the handle 6 is lifted up at this time, that is, the handle 6 is rotated counterclockwise, the first shifting arm 61 drives the first driving arm 51 to rotate clockwise, so as to drive the whole driving member 5 to rotate clockwise, because the blocking member 3 is in a contracted state at this time, the stop block 54 is aligned with the through hole 31, the third driving arm 53 is aligned with the opening 32, and the width (or diameter) of the through hole 31 is larger than the width of the stop block 54, as shown in fig. 7, the third driving arm can pass through the blocking member 3 to rotate clockwise, so that the second driving arm 52 of the driving member 5 can also rotate clockwise continuously to drive the main bolt 2 to extend, thereby achieving the purpose of lifting up the handle 6 to lock the door, and the state is shown in fig. 6.
In addition, this embodiment also provides a door (not shown in the figure), which includes a door body and a lock body disposed on the door body, where the lock body is the lock body described above.
The embodiment also provides a working method of the door, which mainly comprises the following steps:
1) After the door is opened, namely when the door is in an opened state, one part of the blocking piece extends out of the shell, and the blocking piece in the state can block the main lock tongue, so that the main lock tongue cannot extend out of the shell even if a person rotates a handle of the lock body when the door is not closed;
2) After the door is turned to be closed, namely, when the door is in a closed state, the blocking piece is completely retracted into the shell under the action of the door frame, and the blocking piece can release the blocking of the main lock tongue at the moment, so that a person can rotate the handle of the lock body to enable the main lock tongue to extend out of the shell, and the door can be locked normally.
In the present description, the structures of the parts are described in a progressive manner, and the structure of each part is mainly described as a difference from the existing structure, and the whole and part of the structure of the lock body can be obtained by combining the structures of the parts.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
