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 extend or retract the main bolt by inserting a key into the lock cylinder. In existing lock bodies, the key needs to be turned at least one full turn to complete the extension and retraction of the main bolt, which makes the lock body slow to open and close and results in a poor user experience. 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:

[0005] A main locking bolt drive mechanism, comprising:

[0006] Lock case;

[0007] The main bolt is slidably mounted on the lock housing, and the main bolt has an extended working position and a retracted working position;

[0008] The main bolt drive is rotatably mounted on the lock housing and is used to cooperate with the main bolt to drive the main bolt to extend out of or retract into the lock housing.

[0009] The first tooth is disposed on the main lock tongue drive member. The rotation axis of the first tooth coincides with the rotation axis of the main lock tongue drive member. When the first tooth rotates, it can drive the main lock tongue drive member to rotate synchronously.

[0010] A lock cylinder drive is rotatably mounted on the lock housing. The lock cylinder drive has a second tooth that meshes with the first tooth. The lock cylinder drive has a first position and a second position. When the lock cylinder drive is in the first position, the main bolt drive is in the retracted position. When the lock cylinder drive is in the second position, the main bolt drive is in the extended position. The second position of the lock cylinder drive is rotated 50° to 140° relative to the first position of the lock cylinder drive.

[0011] This application's main bolt has a first end and a second end. When the main bolt is in the extended working position, the first end of the main bolt can extend out of the lock housing; when the main bolt is in the retracted working position, the first end of the main bolt can retract into the lock housing. 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. This application achieves continuous transmission through the meshing of the first and second teeth, thereby enabling control of the main bolt's extension and retraction actions at a relatively small angle.

[0012] In one embodiment of the present invention, the second position of the lock cylinder drive member is rotated 90° relative to the first position of the lock cylinder drive member.

[0013] The 90° design allows for small-angle opening and closing operations, which also conforms to user habits and makes it easier to determine whether the key has been turned to the correct position, resulting in a better user experience when opening and closing the lock.

[0014] In one embodiment of the present invention, a positioning elastic element is further included, which is installed on the lock housing and cooperates with the main bolt or the main bolt drive member. The positioning elastic element is used to maintain the main bolt in the extended working position when the main bolt is in the extended working position, and to maintain the main bolt in the retracted working position when the main bolt is in the retracted working position.

[0015] In one embodiment of this utility model, the positioning elastic element is a torsion spring. One end of the positioning elastic element is connected to the lock body, and the other end is connected to the main lock tongue drive element. When the main lock tongue is in the extended working position, the positioning elastic element causes the main lock tongue to have a tendency to continue moving outward. When the main lock tongue is in the retracted working position, the positioning elastic element causes the main lock tongue to have a tendency to continue moving inward into the lock shell.

[0016] In one embodiment of the present invention, the main locking tongue has a clearance space for the first tooth to move.

[0017] As the key turns, the first tooth also rotates. By setting a clearance space, interference between the main bolt and the first tooth can be prevented.

[0018] In one embodiment of the present invention, the first tooth and the main locking tongue are offset along the length direction of the rotation axis of the first tooth.

[0019] This configuration eliminates the need for clearance on the main bolt, ensuring its strength.

[0020] In one embodiment of this utility model, the first tooth is integrally formed with the main locking tongue drive component, or welded and fixed, or fixed by fasteners.

[0021] In one embodiment of this utility model, the first tooth and the main locking tongue drive are connected to each other through a pin hole structure.

[0022] The pin hole structure mentioned in this application refers to a structure in which one of the first tooth and the main locking tongue drive has a pin hole and the other has a pin, with the pin inserted into the pin hole. This structure enables the main locking tongue drive to rotate synchronously when the first tooth rotates.

[0023] 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 mating part that cooperates with the limiting part. When the main bolt is in the extended working position, the limiting part and the mating part interact to prevent the sliding plate from moving. When the main bolt is in the retracted working position, the limiting part and the mating part separate, and the sliding plate can move after being subjected to force.

[0024] In one embodiment of the present invention, the main latch has a notch, and the main latch drive has a drive portion that engages with the notch.

[0025] In one embodiment of the present invention, the lock housing has a first limiting post;

[0026] When the main bolt is in the extended working position, the drive unit abuts against the first limiting post, restricting the main bolt from extending further out of the lock housing;

[0027] The main latch has a first end and a second end. The first end of the main latch can extend out of the lock housing. When the main latch is in the retracted working position, the driving part abuts against the lock housing, or the second end of the main latch abuts against the side wall of the lock housing, or the second end of the main latch abuts against the second limiting post on the lock housing.

[0028] This application also discloses a lock body, including the main bolt drive mechanism described above.

[0029] The beneficial effects of this utility model are: through the meshing of the first tooth and the second tooth, continuous transmission can be achieved, thereby enabling the main locking tongue to extend and retract at a smaller angle. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] The present invention will now be described in detail with reference to the accompanying drawings.

[0041] like Figures 1-3 As shown, this embodiment discloses a lock body, including a main bolt drive mechanism. The main bolt drive mechanism includes:

[0042] Lock case 1;

[0043] 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;

[0044] The main bolt drive 3 is rotatably mounted on the lock housing 1 and 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.

[0045] The first tooth 31 is provided on the main lock tongue drive 3. The rotation axis of the first tooth 31 coincides with the rotation axis of the main lock tongue drive 3. When the first tooth 31 rotates, it can drive the main lock tongue drive 3 to rotate synchronously.

[0046] The lock cylinder drive 4 is rotatably mounted on the lock housing 1. The lock cylinder drive 4 has a second tooth 41 that meshes with the first tooth 31. The lock cylinder drive 4 has a first position and a second position. When the lock cylinder drive 4 is in the first position, the main bolt drive 3 is in the retracted working position. When the lock cylinder drive 4 is in the second position, the main bolt drive 3 is in the extended working position. The second position of the lock cylinder drive 4 is rotated 90° relative to the first position of the lock cylinder drive 4.

[0047] The main bolt 2 of this application has a first end 2a and a second end 2b. When the main bolt 2 is in the extended working position, the first end 2a can extend out of the lock housing 1. When the main bolt 2 is in the retracted working position, the first end 2a can retract into the lock housing 1. In this application, the lock cylinder drive 4 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 4 to rotate synchronously. This application can achieve continuous transmission through the meshing of the first tooth 31 and the second tooth 41, thereby achieving a small angle (90°) to control the extension and retraction of the main bolt 2. The 90° design enables small-angle opening and closing operations and makes it easier for users to determine whether the key has been rotated to the correct position, resulting in a better user experience when opening and closing the lock.

[0048] In practical applications, the rotation angle of the second position of the lock cylinder drive relative to the first position of the lock cylinder drive is not limited to 90°, but can also be between 50° and 140°, which also provides a better user experience.

[0049] like Figure 1 and 2 As shown, in this embodiment, a positioning elastic member 5 is also included, which is installed on the lock housing 1 and cooperates with the main lock tongue 2 or the main lock tongue drive member 3. The positioning elastic member 5 is used to maintain the main lock tongue 2 in the extended working position when the main lock tongue 2 is in the extended working position, and to maintain the main lock tongue 2 in the retracted working position when the main lock tongue 2 is in the retracted working position.

[0050] like Figure 1 and 2As shown, in this embodiment, the positioning elastic element 5 is a torsion spring. One end of the positioning elastic element 5 is connected to the lock body, and the other end is connected to the main lock tongue drive 3. When the main lock tongue 2 is in the extended working position, the positioning elastic element 5 makes the main lock tongue 2 have a tendency to continue moving outward. When the main lock tongue 2 is in the retracted working position, the positioning elastic element 5 makes the main lock tongue 2 have a tendency to continue moving inward into the lock housing 1.

[0051] In this embodiment, the first tooth 31 and the main latch 2 are offset along the length of the rotation axis of the first tooth 31. This arrangement eliminates the need for clearance space on the main latch 2, ensuring its strength. In other embodiments, the main latch 2 has clearance space for the first tooth 31 to move. As the key rotates, the first tooth 31 also rotates; by providing clearance space, interference between the main latch 2 and the first tooth 31 can be prevented.

[0052] In this embodiment, the first tooth 31 is integrally formed with the main locking tongue drive 3, or welded and fixed, or fixed by fasteners.

[0053] In practical applications, the first tooth 31 and the main locking tongue drive 3 can also be connected to each other through a pin hole structure. The pin hole structure mentioned in this application refers to a structure in which one of the first tooth 31 and the main locking tongue drive 3 has a pin hole and the other has a pin, with the pin inserted into the pin hole. This structure enables the main locking tongue drive 3 to rotate synchronously when the first tooth 31 rotates.

[0054] like Figure 4 and 5 As shown, in this embodiment, a sliding plate 6 is also movably disposed on the lock housing 1. The sliding plate 6 is used to control the movement of the deadbolt. The main lock tongue 2 has a limiting part 22, and the sliding plate 6 has a mating part 61 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 mating part 61 interact with each other and can prevent the sliding plate 6 from moving. When the main lock tongue 2 is in the retracted working position, the limiting part 22 and the mating part 61 separate, and the sliding plate 6 can move after being subjected to force.

[0055] like Figure 1 and 2 As shown, in this embodiment, the main latch 2 has a notch 21, and the main latch drive 3 has a drive part 32 that cooperates with the notch 21.

[0056] like Figure 1 and 2 As shown, in this embodiment, the lock case 1 has a first limiting post 11;

[0057] When the main bolt 2 is in the extended working position, the drive unit 32 abuts against the first limiting post 11, restricting the main bolt 2 from extending further out of the lock housing 1;

[0058] The main bolt 2 has a first end and a second end. The first end 2a of the main bolt can extend out of the lock housing 1. When the main bolt 2 is in the retracted working position, the drive part 32 abuts against the lock housing 1, or the second end 2b of the main bolt abuts against the side wall of the lock housing 1, or the second end 2b of the main bolt abuts against the second limiting post 12 on the lock housing 1.

[0059] like Figure 1 and Figure 2 As shown in this application, the rotation direction of the lock cylinder drive 41 is consistent with the movement direction of the main bolt 2. Specifically, in Figure 1 In this state, when the key drives the lock cylinder drive 41 to turn to the right (clockwise), the main bolt 2 moves to the right. Figure 2 In this state, when the key drives the lock cylinder drive 41 to turn to the left (counterclockwise), the main lock tongue 2 moves to the left.

[0060] 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.
