DETAILED DESCRIPTION

[0022] The utility model will be further detailed in the following with the embodiment given by the accompanying drawings.

[0023] Refer to Figures 1-4 As shown in the drawing, the adjustable gear locking structure of the embodiment, including first lock hook 1, second lock hook 2, lock piece 3, drive piece 4, first lock hook 1 rotatable setting, second lock hook 2 rotatable setting or fixed setting, drive piece 4 is provided with the first guide portion 5 of cooperation first lock hook 1, and first lock hook 1 is driven to unfold and gather by the first guide portion 5 of drive piece 4 through activity;Drive piece 4 is provided with a plurality of gear grooves 6 on the position corresponding lock piece 3, and lock piece 3 cooperates with gear groove 6 and locks, and drive piece 4 is limited to move.

[0024] The first locking hook 1 can be rotatably connected with an external mounting carrier or a lock housing 13 through a hinge shaft, and the second locking hook 2 can be rotatably arranged or directly fixed at a preset position of the mounting carrier according to the actual application scenario; the driving member 4 can adopt a linear sliding movement, and a transmission association is established between the driving member 4 and the first locking hook 1 through the first guide part 5. The first guide part 5 can be provided in the form of a protrusion, a groove or an inclined surface, and does not need a complex transmission assembly. The locking member 3 only needs to have an embedding function matched with the gear slot 6, and the structure design is simple and does not need additional auxiliary transmission components. The overall locking structure only includes four core components, i.e., the first locking hook 1, the second locking hook 2, the locking member 3 and the driving member 4, the number of components is small, the structure of each component is simple, there is no redundant design, the material cost and processing difficulty in the production and manufacturing process can be effectively reduced, the assembly process is simplified, and the production efficiency is improved. When the driving member 4 moves, the first guide part 5 will generate a force on the first locking hook 1, prompting the first locking hook 1 to rotate around its rotation support point, and then realizing the unfolding or folding action, so as to change the relative distance between the first locking hook 1 and the second locking hook 2. The plurality of gear slots 6 on the driving member 4 are arranged at intervals along the movement track direction, and the locking member 3 can be telescopically matched with the mounting carrier or the lock housing 13. When the driving member 4 moves to the target gear slot matching the specification of the locking object, the locking member 3 is embedded and matched with the corresponding gear slot 6, thereby limiting the further movement of the driving member 4, and realizing the stable locking of the current gear. Through this design, the movement position of the driving member 4 can be flexibly adjusted to change the unfolding degree of the first locking hook 1 according to different specifications of the reserved through hole or locking position of the locking object (such as a notebook computer, a bicycle, etc.), thereby adapting to locking requirements of various specifications, effectively improving the single adaptability of the existing lock, improving the application scenario coverage of the locking structure, and of course the structure can also be used to adapt to different specifications of a single object, such as different specifications of the reserved through hole of different brands of notebook computers.

[0025] In order to facilitate the synchronous adjustment of the first locking hook 1 and the second locking hook 2, in an optional scheme, the second locking hook 2 is rotatably arranged, and the driving member 4 is provided with a second guide part 7 matched with the second locking hook 2. The driving member 4 drives the first locking hook 1 and the second locking hook 2 to rotate and unfold or fold through the synchronous movement of the first guide part 5 and the second guide part 7.

[0026] The second locking hook 2 is rotationally connected with the mounting carrier through a hinge shaft, and the rotation support point is coaxial with that of the first locking hook 1; the driving member 4 is simultaneously formed with a first guide part 5 and a second guide part 7, the two guide parts form corresponding matching relationships with the first locking hook 1 and the second locking hook 2 respectively, and the structural forms of the two guide parts are consistent to ensure consistent transmission, without the need to design independent driving structures for the two hooks, and the structure continues the simplified design idea. When the driving member 4 moves in a single direction, the first guide part 5 and the second guide part 7 will simultaneously apply directionally matched driving forces to the corresponding hooks, so that the first locking hook 1 and the second locking hook 2 synchronously expand or contract around their respective rotation support points, ensuring that the movement trajectories of the two are symmetrical or in a preset linkage relationship. This synchronous driving structure can make the spacing adjustment between the first locking hook 1 and the second locking hook 2 more accurate, can realize a larger range of spacing adjustment amplitude, and further improves the adaptation ability of the locking structure to different specifications of the locking object, while without the need to separately operate the two hooks, simplifying the operation process of gear adjustment, improving the use convenience, and without increasing additional core components while maintaining the synchronous adjustment function, still maintaining the advantages of simple structure and few components.

[0027] Further optimization can be specifically selected as follows: the first guide part 5 and the second guide part 7 are both sliding grooves 8, the two sliding grooves 8 form an acute angle, the first locking hook 1 and the second locking hook 2 are provided with sliding blocks 9 at positions corresponding to the sliding grooves 8, the sliding blocks 9 slide in the sliding grooves 8, and the driving member 4 moves through the sliding blocks 9 and the sliding grooves 8 to drive the first locking hook 1 and the second locking hook 2 to synchronously expand or contract.

[0028] The sliding blocks 9 on the first locking hook 1 and the second locking hook 2 can adopt a protruding shaft structure integrally formed with the hook body, or a roller pin structure fixed on the hook through simple methods such as threaded connection and welding, without the need for complex connecting members, the outer diameter of the sliding block 9 is matched with the groove width of the sliding groove 8 to ensure smooth sliding; the sliding groove 8 on the driving member 4 is provided in the form of a long strip-shaped through slot or a groove with a groove bottom, the extension direction of the sliding groove 8 and the movement direction of the driving member 4 form a preset angle, and the angle setting can efficiently convert the linear movement or rotational movement of the driving member 4 into rotational driving force of the hook, without the need for additional transmission conversion components. When the driving member 4 moves, the groove wall of the sliding groove 8 will generate a lateral thrust on the sliding block 9, and under the action of the thrust, the sliding block 9 slides along the sliding groove 8 while driving the hook to rotate around its rotation support point, thereby realizing the synchronous expansion or contraction of the first locking hook 1 and the second locking hook 2. The cooperation between the sliding groove 8 and the sliding block 9 is a simple and reliable transmission structure, the transmission process is stable, and the structure design does not increase the number of components, still maintaining the simplicity of the overall structure, avoiding the risk of failure caused by complex transmission structure.

[0029] In some options, the locking member 3 includes a telescopic rod 10 and a password mechanism 11, one end of the telescopic rod 10 extends to the password mechanism 11, and the other end cooperates with the gear slot 6 to enter or exit the gear slot 6. When the telescopic rod 10 enters the gear slot 6 and the password mechanism 11 locks the telescopic rod 10, the telescopic rod 10 cooperates with the gear slot 6 to lock the driving member 4.

[0030] The password mechanism 11 is fixedly installed on the installation carrier by screws or buckles, and the inside is provided with a locking assembly (such as a pin tumbler lock core, a clamping slot type locking structure, etc.) adapted to the telescopic rod 10; the telescopic rod 10 is telescopically arranged along its axis direction, one end of the telescopic rod 10 is inserted into the locking cavity inside the password mechanism 11, and cooperates with the locking assembly; when the password mechanism 11 is in the locked state, the locking assembly restricts the telescopic movement of the telescopic rod 10; when the correct password is input, the locking assembly releases the constraint on the telescopic rod 10, and the unlocking is realized. The other end of the telescopic rod 10 is a free end, the shape of the end is adapted to the shape of the notch of the gear slot 6, and the telescopic rod 10 can enter or exit the gear slot 6 on the driving member 4 under the telescopic force (for example, the pushing force of a manual lever fixed on the telescopic rod 10). The locking member 3 is only composed of the telescopic rod 10 and the password mechanism 11, the component structure is simple, there is no complex control module or transmission component, the overall structure can be maintained simple while ensuring the locking function and the security of anti-theft. When the driving member 4 is adjusted to the target gear, the free end of the telescopic rod 10 enters the corresponding gear slot 6 under the external force or the assistance of the elastic member, at this time the password mechanism 11 is in the locked state, the telescopic rod 10 cannot be telescopically moved, and then the activity of the driving member 4 is restricted through the embedded cooperation with the gear slot 6, so that the gear is stably locked; when the gear needs to be switched, the correct password is input to unlock the password mechanism 11, the telescopic rod 10 restores the telescopic freedom, at this time the driving member 4 can be pushed to adjust the position. The structure of the locking member 3 realizes the unlocking permission control through the password mechanism 11, improves the security of the locking structure, avoids the random adjustment of the gear by unauthorized personnel, the embedded cooperation of the telescopic rod 10 and the gear slot 6 is reliable, the operation process is simple, and the simple structure design reduces the failure probability and the manufacturing cost of the locking member 3.

[0031] In order to improve the cooperation fluency of the telescopic rod 10 and the gear slot 6, in an optional scheme, a spring 12 is arranged between the telescopic rod 10 and the password mechanism 11, and the spring 12 keeps the telescopic rod 10 in the movement trend of entering the gear slot 6; the gear slot 6 is triangular, and one end of the telescopic rod 10 corresponding to the gear slot 6 is adapted to the shape of the gear slot 6; when the password mechanism 11 unlocks the telescopic rod 10, the gear slot 6 guides the telescopic rod 10 to exit the gear slot 6, and the telescopic rod 10 compresses the corresponding spring 12; when the telescopic rod 10 corresponds to another gear slot 6, the telescopic rod 10 enters the gear slot 6 under the action of the spring 12.

[0032] The spring 12 is sleeved outside the telescopic rod 10, or embedded in the mounting cavity between the telescopic rod 10 and the password mechanism 11, one end of the spring 12 abuts against the shell 13 of the password mechanism 11 or a fixed component therein, and the other end abuts against the stepped surface of the telescopic rod 10. In the natural state, the spring 12 is in the stretched state (a certain compression amount can be maintained, and the stretched state is relative to the compressed state), a continuous pushing force is applied to the telescopic rod 10 in the direction of the gear slot 6, so that the telescopic rod 10 always maintains a movement trend of entering the gear slot 6. The spring 12 is a common elastic component, which is simple in structure and low in cost, and does not increase the complexity of the overall structure. The gear slot 6 is provided in a triangular structure, two sides of which are inclined guide surfaces. The end of the telescopic rod 10 corresponding to the gear slot 6 is provided in a conical or triangular structure matched with the triangular gear slot 6, so as to ensure the fit degree when the two are in contact. This shape design does not require complex processing technology and is easy to realize. When the password mechanism 11 is unlocked, the driving part 4 is pushed to move, the inclined guide surface of the gear slot 6 will form contact with the end of the telescopic rod 10, and the lateral component force generated by the guide surface will overcome the pushing force of the spring 12, so as to push the telescopic rod 10 to move away from the gear slot 6, and at the same time, the spring 12 is compressed, so that the telescopic rod 10 smoothly separates from the current gear slot 6. With the continuous movement of the driving part 4, when the telescopic rod 10 moves to the position of the next gear slot 6, the telescopic rod 10 quickly extends into the gear slot 6 under the elastic pushing force of the spring 12, so as to realize automatic switching and locking of the gear. The triangular gear slot 6 and the telescopic rod 10 end matched in shape can effectively guide the ejection and entry action of the telescopic rod 10, and cooperate with the elastic force of the spring 12, so that the gear adjustment process does not need to manually operate the telescopic rod 10, and the gear switching can be completed by only pushing the driving part 4, which improves the convenience of the adjustment operation. At the same time, the setting of the spring 12 can ensure that the telescopic rod 10 and the gear slot 6 are closely matched, improve the stability of the locking state, and the newly added spring 12 component is simple in structure and does not change the core advantages of the overall locking structure, such as fewer components and simple structure.

[0033] Specifically, the password mechanism 11 can be a password wheel mechanism.

[0034] The password wheel mechanism includes several independently rotatable password wheels, and the inside of the password wheel mechanism has a locking assembly cooperating with the telescopic rod 10 (the password wheel and the locking assembly are both mature prior art, and the telescopic rod 10 in the present scheme can be understood as the lock rod of a conventional password wheel chain lock. The lock rod is locked and movable by locking and unlocking the password wheel). When the correct password marks on each password wheel are aligned by rotating the password wheel, the locking assembly will displace and release the restriction on the telescopic rod 10, achieving password unlocking; when the positions of the password wheels are not aligned with the correct password, the locking assembly remains in the locked state of the telescopic rod 10, restricting its telescopic movement. The cooperation of the password wheel mechanism and the telescopic rod 10 can simplify the structure, facilitate production and reduce costs.

[0035] Based on the above adjustable gear locking structure, the present embodiment further provides a lock structure, which comprises a shell 13 and an adjustable gear locking structure installed in the shell 13; the shell 13 has an opening 14, the hook portions of the first and second lock hooks 1 and 2 extend out of the shell 13 through the opening 14 and expand or contract in the opening 14; the first and second lock hooks 1 and 2 are both rotationally connected in the shell 13, and the driving member 4 is slidingly connected with the shell 13.

[0036] The shell 13 serves as an integrated installation carrier of the lock structure, and its inside is formed with a containing cavity by injection molding or machining, for installing various functional components of the adjustable gear locking structure. The material of the shell 13 can be selected from high-strength plastic or metal alloy to balance light weight and structural strength. The shell 13 is designed simply, only needs to provide installation space and necessary matching structure, and does not need complex internal cavity design. The first and second lock hooks 1 and 2 are rotationally connected in the containing cavity of the shell 13 through a hinge shaft, the two ends of the hinge shaft are fixed on the side walls of the shell 13 to ensure the stability of the rotation fulcrum, and the hook portions of the two are arranged towards the opening 14 of the shell 13. The hook portions are designed in L shape or arc shape to adapt to the edge structure of the through hole of the locking object, can reliably hook the locking object after expansion, and have simple structure and reliable locking effect. The driving member 4 is slidingly connected through the slide rail or slide groove 8 structure provided on the shell 13. The sliding matching structure is simple, does not have complex guiding components, and the specific guidance can be directly realized by the inner wall of the shell 13. The overall lock structure only adds one shell 13 component based on the adjustable gear locking structure, does not significantly increase the number of components, still maintains the advantage of simple structure, and the integrated design of the shell 13 makes the lock more convenient to carry and use. The end of the driving member 4 can be exposed outside the shell 13, facilitating the user to operate, such as pushing or pulling.

[0037] In order to keep the lock hooks contracted in the non-use state, in an optional scheme, a spring 12 is arranged in the shell 13, which is connected with the driving member 4 to keep the driving member 4 in the movement trend of contracting the first and second lock hooks 1 and 2.

[0038] The spring 12 is installed in the shell 13, one end of the spring 12 is fixedly connected with the inner wall of the shell 13 through a hook or buckle structure, or directly abuts against a fixed position inside, the other end is fixedly connected or abuts against the connecting part of the driving piece 4, in the natural state, the spring 12 is in the stretched or compressed state, and continuously acts on the driving piece 4 in the direction of closing the lock hook. The spring 12 is a simple elastic component, and does not increase the complexity of the lock structure. When the user releases the driving piece 4, the driving piece 4 will automatically slide in the direction of closing the lock hook under the action of the spring 12, and then drive the first lock hook 1 and the second lock hook 2 to be closed synchronously through the cooperation of the guide part and the sliding block 9, so that the hook part of the lock hook is withdrawn to the inside of the opening 14 of the shell 13 or kept in a compact closed state. The arrangement of the spring 12 can realize automatic closing and resetting of the lock hook, avoid the lock hook from being damaged by collision or causing scratches to the user when not in use, and only need to overcome the action of the spring 12 to push the driving piece 4 to expand the lock hook to the target gear position during the locking process. The action of the spring 12 can assist in keeping the position of the driving piece 4 stable after being released, further improving the convenience and safety of the lock. The newly added spring 12 component has simple structure and low cost, and does not change the core characteristics of the lock with few components and overall simplification.

[0039] Specifically, the following optimization can be selected. The shell 13 is in a T shape, including a horizontal section 15 and a vertical section 16. The opening 14 and the driving piece 4 are located at two ends of the horizontal section 15, and the locking piece 3 is located on the vertical section 16. A space for fingers to pass through is formed between one end of the horizontal section 15 corresponding to the opening 14 and the vertical section 16.

[0040] The horizontal section 15 and the vertical section 16 of the shell 13 are integrally formed. The length direction of the horizontal section 15 is perpendicular to the length direction of the vertical section 16, forming a T-shaped layout. One end of the horizontal section 15 is provided with the opening 14 for the lock hook to extend out, and the other end is provided with a mounting position of the driving piece 4. The operation end of the driving piece 4 is exposed outside the horizontal section 15, which is convenient for the user to manually push. The vertical section 16 is perpendicularly connected at the middle position of the horizontal section 15. The locking piece 3 (such as a password wheel mechanism) is installed on the outside or inside of the vertical section 16. The operation surface (such as the rotating surface of the password wheel) of the locking piece 3 is exposed on the side surface of the vertical section 16, which is convenient for the user to input the password. The space formed between one end of the horizontal section 15 corresponding to the opening 14 and the vertical section 16 is suitable for the size of the fingers. The user can hold the vertical section 16 by passing the fingers through the space, which is convenient for providing a force point to operate the password wheel and the driving piece 4. The T-shaped shell 13 has a compact and reasonable design layout, which can effectively integrate the mounting positions of the driving piece 4, the locking piece 3 and the lock hook, so that the operation areas of the components do not interfere with each other, and the overall portability and use safety of the lock are improved.

[0041] Based on the above lock structure, the embodiment further provides a computer lock comprising the lock structure.

[0042] The computer lock adopts the lock structure as the core locking component, the shell 13 of the lock structure can reserve a cable connection interface, the computer lock is connected with a fixed object (such as an office table, a railing, etc.) through a cable, the cable can be made of steel cable material to improve the shear resistance, and the connection mode of the cable and the shell 13 is simple and reliable, without complex fixing structure.

[0043] The above only is preferred implementation manner of the utility model, the protection scope of the utility model is not only limited to the above embodiment, and all technical solutions under the idea of the utility model belong to the protection scope of the utility model for the person skilled in the art of the utility model. It should be pointed out that, for the ordinary skilled in the art, some improvements and decorations without departing from the principle of the utility model are also regarded as the protection scope of the utility model.
