Description

Technical Field

[0001] This utility model relates to the field of locks, specifically to a main bolt drive mechanism and a lock body. Background Technology

[0002] The lock body can drive the main bolt to extend or retract by inserting a key into the lock cylinder. In existing lock bodies, in order to make the direction of key rotation consistent with the direction of main bolt movement, a complex transmission structure needs to be designed, making the entire structure quite complex. Utility Model Content

[0003] This invention addresses the aforementioned problems by proposing a main bolt drive mechanism and a lock body.

[0004] The technical solution adopted by this utility model is as follows: A main locking bolt drive mechanism, comprising: Lock case; The main bolt is slidably mounted on the lock housing, and the main bolt has an extended working position and a retracted working position; The main bolt drive is rotatably mounted on the lock housing. The main bolt drive has a first mating part and a second mating part, which are located on both sides of the rotation axis of the main bolt drive. The first mating part is used to engage with the main bolt to drive the main bolt to extend out of or retract into the lock housing. A transmission component is rotatably mounted on the lock housing. The transmission component has a first transmission part, a second transmission part, and a third transmission part. The first transmission part is located on one side of the rotation axis of the transmission component, and the second and third transmission parts are located on the other side of the rotation axis of the transmission component. The first transmission part cooperates with the second mating part of the main lock tongue drive component. When the transmission component rotates, it can drive the main lock tongue drive component to rotate through the transmission of the first transmission part and the second mating part. A lock cylinder drive is rotatably mounted on the lock housing. The lock cylinder drive has a drive part, which cooperates with the second transmission part and the third transmission part to drive the transmission part to rotate. When the lock cylinder drive rotates, the rotation direction of the lock cylinder drive is consistent with the movement direction of the main lock tongue.

[0005] This application has a simple structure and achieves transmission through a transmission component, which enables the rotation direction of the lock cylinder drive component to be consistent with the movement direction of the main lock tongue.

[0006] In this application, the lock cylinder drive component can be an independent part, driven to rotate by the lock cylinder, or it can be part of the lock cylinder. When the key is inserted into the lock cylinder, the key can drive the lock cylinder drive component to rotate synchronously.

[0007] In one embodiment of the present invention, the lock housing has a first side and a second side disposed opposite to each other, and the main bolt can extend out of the first side; The second transmission unit is closer to the first side than the third transmission unit; When the driving unit rotates towards the first side of the lock housing, the first transmission unit rotates towards the second side, driving the main bolt drive member to rotate, causing the main bolt to extend out of the first side; when the driving unit rotates towards the second side of the lock housing, the first transmission unit rotates towards the first side, driving the main bolt drive member to rotate, causing the main bolt to retract back to the first side. That is, the rotation direction of the lock cylinder drive member is consistent with the movement direction of the main bolt.

[0008] In one embodiment of the present invention, the driving part is located between the second transmission part and the third transmission part.

[0009] In one embodiment of the present invention, a clearance space is formed between the transmission member and the lock housing for the main lock tongue to move. The transmission member has a plate-shaped body, which is spatially offset from the driving part. One end of the second transmission part and the third transmission part are both connected to the plate-shaped body, and the other end of both are bent toward the clearance space.

[0010] Because the transmission components need to avoid the main locking tongue, the second and third transmission parts are positioned relatively off-center, not in the middle area of ​​the lock housing space, making it difficult to reliably cooperate with the drive unit. The design of the second and third transmission parts bending towards the side of the clearance space facilitates processing and allows the second and third transmission parts to better contact and cooperate with the drive unit.

[0011] In one embodiment of this utility model, the plate-shaped body, the second transmission part, and the third transmission part are an integral piece.

[0012] In one embodiment of the present invention, the lock housing has a first limiting post and a second limiting post; When the main bolt is in the extended working position, the main bolt drive unit abuts against the first limiting post, restricting the main bolt from extending further out of the lock housing; When the main bolt is in the retracted position, the main bolt drive unit abuts against the second limiting post, restricting the main bolt from retracting further into the lock housing.

[0013] In one embodiment of the present invention, the first transmission part is a slide groove, and the first mating part extends into the slide groove.

[0014] In one embodiment of the present invention, the transmission member further has a clearance groove, the main locking tongue drive member has a rotating shaft, and one end of the rotating shaft of the main locking tongue drive member extends into the clearance groove. The clearance groove may or may not be connected to the slide groove.

[0015] In one embodiment of the present invention, the main locking tongue has a notch, and the first mating part mates with the notch.

[0016] In one embodiment of this utility model, a sliding plate movably disposed on the lock housing is also included. The sliding plate is used to control the movement of the deadbolt and the main bolt. The main bolt has a limiting part, and the sliding plate has a positioning part that cooperates with the limiting part. When the main bolt is in the extended working position, the limiting part and the positioning part interact to prevent the sliding plate from moving. When the main bolt is in the retracted working position, the limiting part and the positioning part separate, and the sliding plate can move after being subjected to force.

[0017] This application also discloses a lock body, including the main bolt drive mechanism described above.

[0018] The beneficial effects of this utility model are: the structure of this application is simple, and the transmission is realized through the transmission component, which can realize that the rotation direction of the lock cylinder drive component is consistent with the movement direction of the main lock tongue.

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, a lock body is disclosed, including a main bolt drive mechanism, which includes: Lock case 1; The main bolt 2 is slidably mounted on the lock housing 1, and the main bolt 2 has an extended working position and a retracted working position; The main bolt drive 3 is rotatably mounted on the lock housing 1. The main bolt drive 3 has a first mating part 31 and a second mating part 32. The first mating part 31 and the second mating part 32 are located on both sides of the rotation axis 33 of the main bolt drive 3. The first mating part 31 is used to cooperate with the main bolt 2 to drive the main bolt 2 to extend out of the lock housing 1 or retract into the lock housing 1. The transmission component 4 is rotatably mounted on the lock housing 1. The transmission component 4 has a first transmission part 41, a second transmission part 42, and a third transmission part 43. The first transmission part 41 is located on one side of the rotation axis 33 of the transmission component 4, and the second transmission part 42 and the third transmission part 43 are located on the other side of the rotation axis 33 of the transmission component 4. The first transmission part 41 cooperates with the second mating part 32 of the main lock tongue drive component 3. When the transmission component 4 rotates, it can drive the main lock tongue drive component 3 to rotate through the transmission of the first transmission part 41 and the second mating part 32. The lock cylinder drive 5 is rotatably mounted on the lock housing 1. The lock cylinder drive 5 has a drive part 51, which cooperates with the second transmission part 42 and the third transmission part 43 to drive the transmission part 4 to rotate. When the lock cylinder drive 5 rotates, the rotation direction of the lock cylinder drive 5 is consistent with the movement direction of the main lock tongue 2.

[0026] This application has a simple structure and achieves transmission through the transmission component 4, which enables the rotation direction of the lock cylinder drive component 5 to be consistent with the movement direction of the main lock tongue 2.

[0027] In this application, the lock cylinder drive component 5 can be an independent component, driven to rotate by the lock cylinder, or it can be part of the lock cylinder. When the key is inserted into the lock cylinder, the key can drive the lock cylinder drive component 5 to rotate synchronously.

[0028] In this embodiment, the lock case 1 has a first side 11 and a second side 12 disposed opposite to each other, and the main bolt 2 can extend out of the first side 11; The second transmission unit 42 is closer to the first side 11 than the third transmission unit 43; When the drive unit 51 rotates toward the first side 11 of the lock housing 1, the first transmission unit 41 rotates toward the second side 12, driving the main bolt drive member 3 to rotate, causing the main bolt 2 to extend out of the first side 11; when the drive unit 51 rotates toward the second side 12 of the lock housing 1, the first transmission unit 41 rotates toward the first side 11, driving the main bolt drive member 3 to rotate, causing the main bolt 2 to retract into the first side 11. That is, the rotation direction of the lock cylinder drive member 5 is consistent with the movement direction of the main bolt 2.

[0029] In this embodiment, the drive unit 51 is located between the second transmission unit 42 and the third transmission unit 43.

[0030] In this embodiment, a clearance space 6 is formed between the transmission component 4 and the lock housing 1 for the main lock tongue 2 to move. The transmission component 4 has a plate-shaped body 44, which is spatially offset from the drive unit 51. One end of the second transmission unit 42 and the third transmission unit 43 are both connected to the plate-shaped body 44, and the other end is bent toward the clearance space 6.

[0031] Because the transmission component 4 needs to avoid the main locking tongue 2, the second transmission part 42 and the third transmission part 43 are located at a relatively off-center position, not in the middle area of ​​the lock housing 1 space, making it difficult to reliably cooperate with the drive part 51. The design of the second transmission part 42 and the third transmission part 43 bending towards the avoidance space 6 not only facilitates processing, but also allows the second transmission part 42 and the third transmission part 43 to better contact and cooperate with the drive part 51.

[0032] In this embodiment, the plate-shaped body 44, the second transmission part 42, and the third transmission part 43 are integrated into one piece.

[0033] In this embodiment, the lock housing 1 has a first limiting post 13 and a second limiting post 14; When the main bolt 2 is in the extended working position, the main bolt drive 3 abuts against the first limiting post 13, restricting the main bolt 2 from extending further out of the lock housing 1; When the main bolt 2 is in the retracted working position, the main bolt drive 3 abuts against the second limit post 14, restricting the main bolt 2 from retracting further into the lock housing 1.

[0034] In this embodiment, the first transmission part 41 is a slide groove, and the first mating part 31 extends into the slide groove.

[0035] In this embodiment, the transmission member 4 also has a clearance groove 45, and the main lock tongue drive member 3 has a rotating shaft 33, one end of the rotating shaft 33 of the main lock tongue drive member 3 extending into the clearance groove 45. The clearance groove 45 may or may not be connected to the slide.

[0036] In this embodiment, the main locking tongue 2 has a notch 21, and the first mating part 31 mates with the notch 21.

[0037] In this embodiment, a sliding plate 7 is also movably disposed on the lock housing 1. The sliding plate 7 is used to control the movement of the deadbolt. The main lock tongue 2 has a limiting part 22. The sliding plate 7 has a positioning part 71 that cooperates with the limiting part 22. When the main lock tongue 2 is in the extended working position, the limiting part 22 and the positioning part 71 interact with each other and can prevent the sliding plate 7 from moving. When the main lock tongue 2 is in the retracted working position, the limiting part 22 and the positioning part 71 separate, and the sliding plate 7 can move after being subjected to force.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the scope of patent protection of the present utility model. Any equivalent structural transformations made based on the content of the present utility model specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present utility model.
