Description

Technical Field

[0001] This invention relates to the field of lock technology, and in particular to a non-gear type locking structure. Background Technology

[0002] In existing technologies, the latch structure is simple, consisting of a latch ring and a mounting plate. The latch ring and mounting plate are generally an integral structure, directly fixed to the object via the mounting plate. When the lock body engages with the latch ring, it locks securely. This type of latch is commonly used in automobiles, homes, and other machinery. However, to facilitate the connection between the lock body and the latch ring, the latch ring and mounting plate are generally externally mounted. When not in use, the latch protrudes, which restricts space utilization and reduces space efficiency. Furthermore, this protrusion affects the security and aesthetics of the device, failing to meet user needs. Summary of the Invention

[0003] The technical problem to be solved by this invention is: how to solve the problem of reduced space utilization, safety and aesthetics of the device caused by the protruding state of the existing latch.

[0004] To address the aforementioned technical problems, this invention provides a non-gear-type locking structure, comprising:

[0005] Mounting bracket,

[0006] A guide sleeve is provided on the mounting bracket. The guide sleeve has a hollow structure. One end of the guide sleeve is provided with a first groove, and the side wall of the guide sleeve is provided with a second groove.

[0007] A limiting block is movably disposed within the guide sleeve, and a rack is provided on the side of the limiting block facing the second slot.

[0008] A buckle is provided at the end of the limiting block facing the first slot, and the buckle can extend out of the guide sleeve through the first slot;

[0009] A non-full gear disk, rotatably mounted on a mounting bracket and corresponding to the second slot, the non-full gear disk comprising a smooth section and a gear section, the gear section meshing with the rack; and

[0010] A cable is wound around the non-full gear disc.

[0011] More preferably, the limiting block is further provided with a first limiting arc and a second limiting arc on the side facing the second slot. The first limiting arc and the second limiting arc are respectively placed on both sides of the rack, and both the first limiting arc and the second limiting arc can cooperate with the smooth surface section of the non-full gear disk.

[0012] More preferably, the non-full gear disk is provided with an elastic element slot, and an elastic element is provided in the elastic element slot. Under the action of the elastic element, the non-full gear disk always has a torque to rotate in the M direction.

[0013] More preferably, the elastic element is one of a planar spiral spring, a helical torsion spring, a compression spring, or a tension spring.

[0014] More preferably, it also includes a rotating shaft, wherein the non-gear disk has a shaft hole in the middle, and the rotating shaft passes through the shaft hole.

[0015] More preferably, a winding ring is coaxially provided on the non-gear disk, and a cable groove is provided on the circumferential wall of the winding ring, with the cable placed in the cable groove.

[0016] More preferably, it also includes a cable clip, which is disposed on the mounting bracket, the cable clip being disposed facing the cable groove, and the cable passing through the cable clip.

[0017] More preferably, a first limiting step is formed at the connection between the buckle and the limiting block, and a second limiting step is formed at the junction of the internal cavity of the limiting block and the first slot, with the first limiting step and the second limiting step cooperating with each other.

[0018] More preferably, the buckle includes an engaging portion and an anti-disengagement block, the engaging portion being connected to the limiting block, and the anti-disengagement block being located on the side of the engaging portion away from the limiting block.

[0019] More preferably, the meshing portion is provided with a stiffening reinforcement extending toward the limiting block.

[0020] The advantages of the non-gear-type locking structure provided by this invention compared with the prior art are as follows:

[0021] This invention connects a cable to a non-full gear disc. When the cable is pulled and the non-full gear disc rotates counterclockwise, the gear segment on the non-full gear disc meshes with the rack on the limiting block, causing the limiting block to move away from the first slot within the guide sleeve. At this time, the retaining ring retracts into the guide sleeve along the P direction with the limiting block, achieving a concealed effect. Conversely, when the non-full gear disc rotates clockwise, the retaining ring extends out of the guide sleeve along the N direction for connection with the lock body. This invention utilizes a non-full gear disc to achieve the retraction and extension of the retaining ring, improving equipment space utilization, safety, and aesthetics. Furthermore, its structure is simple, with few related parts, light weight, and high reliability, making it suitable for various lock body structures. Attached Figure Description

[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] In the description of this invention, it should be understood that the terms "inner", "outer", "between", "near", "far away", "extend...outer", "retract...inner", "relative", "clockwise", "counterclockwise", etc., used to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0034] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection via an intermediate medium; or a connection within two components. Those skilled in the art will understand the specific meaning of these terms in this invention based on the specific circumstances.

[0035] like Figure 1As shown, the present invention provides a non-gear type locking structure, including a mounting bracket 1, a guide sleeve 2, a limiting block 3, a buckle 4, a non-gear disc 5, and a cable 6.

[0036] In some examples of the present invention, the guide sleeve 2 is disposed on the mounting bracket 1, and the guide sleeve 2 is a hollow structure. The limiting block 3 is movably disposed inside the guide sleeve 2, and the buckle 4 is connected to the limiting block 3 to realize the extension and retraction function of the buckle 4. The guide sleeve 2 is used to limit the displacement of the buckle 4 while ensuring strength.

[0037] It should be noted that one end of the guide sleeve 2 is provided with a first groove 22, and the buckle 4 is provided at the end of the limiting block 3 facing the first groove 22. The buckle 4 can extend out of the guide sleeve 2 through the first groove 22. The side wall of the guide sleeve 2 is provided with a second groove 23, and the non-full gear disk 5 can be linked with the limiting block 3 through the second groove 23.

[0038] In addition, since the volume of the buckle 4 and the limiting block 3 is fixed in the horizontal direction, in order to reduce the size and cost of the guide sleeve 2, an avoidance slot 21 can be opened at the end of the guide sleeve 2 away from the first slot 22. When the buckle 4 retracts into the guide sleeve 2, at least part of the limiting block 3 can extend out of the guide sleeve 2 through the avoidance slot 21. Without affecting the extension and retraction of the buckle 4, the cost of the locking structure is reduced, and the installation of the limiting block 3 and the buckle 4 is also convenient.

[0039] In some examples of the present invention, in order to achieve linkage between the non-full gear disk 5 and the limiting block 3, the limiting block 3 is provided with a rack 33 on the side facing the second slot 23. At the same time, the non-full gear disk 5 includes a smooth section 52 and a gear section 53. The gear section 53 is meshed with the rack 33. When the non-full gear disk 5 rotates so that the gear section 53 meshes with the rack 33, it drives the limiting block 3 to move in the guide sleeve 2, that is, to move along the P or N direction, thereby realizing that the buckle 4 retracts into the guide sleeve 2 and hides or extends out of the guide sleeve 2 and connects with the lock body.

[0040] In addition, to effectively limit the movement of the limiting block 3 along the P or N direction, a first limiting arc 31 and a second limiting arc 32 are also provided on the side of the limiting block 3 facing the second slot 23. The first limiting arc 31 and the second limiting arc 32 are respectively located on both sides of the rack 33, and both the first limiting arc 31 and the second limiting arc 32 can cooperate with the smooth surface section 52 of the non-full gear disk 5. Figure 1 As shown, when the smooth section 52 of the non-full gear disk 5 engages with the first limiting arc 31 or the second limiting arc 32, the non-full gear disk 5 will not cause the limiting block 3 to move along the P or N direction even if it continues to rotate.

[0041] In some examples of the present invention, the cable 6 is wound around the non-full gear disk 5. When the cable 6 is under force, it pulls the non-full gear disk 5 to rotate counterclockwise. When the gear segment 53 on the non-full gear disk 5 meshes with the rack 33, the limiting block 3 is driven to move along the P direction. When the tension of the cable 6 decreases or disappears, in order to allow the buckle 4 to extend out of the guide sleeve 2, an elastic element groove 57 can be provided on the non-full gear disk 5. An elastic element is provided in the elastic element groove 57. Under the action of the elastic element, the non-full gear disk 5 always has a torque to rotate in the M direction, ensuring that the buckle 4 is in the extended state when the cable 6 and other components fail. When the tension of the cable 6 is less than the torque of the elastic element, the non-full gear disk 5 rotates clockwise, the gear segment 53 meshes with the rack 33, and the limiting block 3 moves along the N direction, thereby pushing the buckle 4 out of the guide sleeve 2 for easy connection with the lock body.

[0042] In the above example, the elastic element is one of a planar spiral spring, a helical torsion spring, a compression spring, or a tension spring. In order to achieve a larger rotation angle of the non-full gear disk 5, the elastic element is generally set as a planar spiral spring. In order to save certain costs, the elastic element can also be set as a helical torsion spring, a compression spring, or a tension spring. In short, any power source that can provide elastic force along the M direction is acceptable.

[0043] In some examples of the present invention, a rotating shaft 51 is also included, and a shaft hole 55 is provided in the middle of the non-full gear disk 5, through which the rotating shaft 51 passes; in other ways, the rotating shaft 51 can be integrated with the non-full gear disk 5, in which case a gear shaft hole needs to be provided on the mounting bracket 1 to cooperate with it.

[0044] In some examples of the present invention, a winding ring 54 is coaxially provided on the non-full gear disk 5, and a cable groove 56 is provided on the circumferential wall of the winding ring 54. The cable 6 is placed in the cable groove 56 to achieve orderly winding of the cable 6 and improve the effectiveness of transmission.

[0045] In some examples of the present invention, a first limiting step is formed at the connection between the buckle 4 and the limiting block 3, and a second limiting step is formed at the junction of the internal cavity of the limiting block 3 and the first slot 22. The first limiting step and the second limiting step cooperate to limit the buckle 4, so that the limiting block 3 can only move linearly along the P direction or N direction within the guide sleeve 2. Setting the limiting step can limit the displacement of the buckle 4 while ensuring strength.

[0046] In some examples of the present invention, the buckle 4 includes an engagement portion 41. To prevent the buckle 4 from deforming and disengaging when it engages with the lock body under force, an anti-disengagement block 43 is provided on the side of the engagement portion 41 away from the limiting block 3. The anti-disengagement block 43 and the buckle 4 are generally separate welded structures.

[0047] In addition, to ensure the rigidity and strength requirements of the retaining ring 4 in the working state, a rigidity reinforcement part 42 can be added between the meshing part 41 and the limiting block 3.

[0048] In other examples of the present invention, the mounting bracket 1 is provided with mounting holes, and the relative positions and dimensions of the mounting bracket 1 and the mounting holes need to be determined according to the installation and docking dimensions of the equipment.

[0049] In other examples of the invention, a cable clip 7 is also included, which is disposed on the mounting bracket 1. The cable clip 7 is disposed facing the cable groove 56, that is, the cable clip 7 is disposed in the tangential direction of the winding ring 54. One end of the cable 6 is led out through the cable clip 7 and connected to the power source, thereby protecting the cable 6 and other components.

[0050] The working process of this invention is as follows:

[0051] Assembly steps are as follows: Please refer to Figure 1-2 First, insert the buckle 4 into the guide sleeve 2 along the N direction from the clearance slot 21 at the end of the guide sleeve 2 until the engagement part 41 extends out of the guide sleeve 2 through the first slot 22, and limit its continued movement by the limiting step; fix the anti-detachment block 43 to the buckle 4 (e.g., by welding or riveting); assemble the elastic element and the non-full gear disk 5 onto the mounting bracket 1; fit the cable 6 into the cable groove 56 of the winding ring 54, thereby completing the assembly process; when a stiffness reinforcement part 42 is provided, the anti-detachment block 43 and the stiffness reinforcement part 42 are generally set with the same diameter, then the above assembly process can simplify the steps of fixing the anti-detachment block 43 to the buckle 4;

[0052] The usage steps are as follows: Please refer to... Figure 1-2 When the cable 6 is under tension, and its tension overcomes the M-direction torque of the elastic element, the cable 6 will pull the non-full gear disk 5 to rotate in the opposite direction of the M-direction against the elastic force. Through the meshing of the gear segment 53 and the rack 33, it will drive the limiting block 3 to move in the P-direction until the retaining ring 4 no longer protrudes from the surface of the equipment. When the non-full gear disk 5 continues to rotate, the smooth segment 52 will slide relative to the first limiting arc 31, and the limiting block 3 will not continue to move in the P-direction. Conversely, when the cable 6 is released, the non-full gear disk 5 will rotate in the M-direction under the action of the elastic force of the elastic element. The meshing of the gear segment 53 and the rack 33 will drive the limiting block 3 to move in the N-direction until the retaining ring 4 is fully in the working (extended) state. When the non-full gear disk 5 continues to rotate, the smooth segment 52 will slide relative to the second limiting arc 32, and the limiting block 3 will not continue to move in the N-direction.

[0053] In summary, this invention provides a non-full gear locking structure in which a cable 6 is wound and connected to a non-full gear disk 5. When the cable 6 is pulled and the non-full gear disk 5 rotates counterclockwise, when the gear segment 53 on the non-full gear disk 5 meshes with the rack 33 on the limiting block 3, the limiting block 3 can be driven to move away from the first slot 22 within the guide sleeve 2. At this time, the retaining ring 4 retracts into the guide sleeve 2 along the P direction with the limiting block 3, thus achieving a hidden effect. Conversely, when the non-full gear disk 5 rotates clockwise, the retaining ring 4 can extend out of the guide sleeve 2 along the N direction for connection with the lock body. This invention utilizes the non-full gear disk 5 to achieve the telescopic function of the retaining ring 4, which can improve the space utilization, safety, and aesthetics of the equipment. Moreover, its structure is simple, with few related parts, light weight, and high reliability, and it is suitable for various lock body structures.
