Description

Technical Field

[0001] This invention belongs to the field of computer lock technology, and specifically refers to a computer lock. Background Technology

[0002] A laptop lock, also known as a notebook anti-theft lock, is a lock specifically designed for portable electronic devices such as laptops and tablets. One side of the lock body has a bolt that can be inserted into the keyhole of the electronic device to lock or unlock it. This bolt, controlled by a mechanical structure, can open and close, thereby engaging the inner wall of the keyhole or being pulled out of it. The other side of the lock body is usually equipped with a high-strength cable or similar object to secure the laptop lock in a specific location or area.

[0003] Currently, electronic device locks on the market generally come in three types: standard locks, nano locks, and wedge locks. These three types of locks have different length and width dimensions (e.g., 3*5, 2.5*6, 3*7). However, the opening and closing stroke of existing computer locks is mostly fixed, meaning that a single type of lock can only fit locks of a specific length. When a user owns multiple electronic devices with different lock sizes, they need to purchase locks of the corresponding specifications for each electronic device or lock size. This not only increases the user's operating costs but also causes inconvenience in carrying and managing multiple locks. Summary of the Invention

[0004] The main objective of this invention is to provide a computer lock that solves the problems existing in the prior art, enabling a single computer lock to simultaneously adapt to keyholes of multiple sizes.

[0005] To achieve the above objectives, the solution of the present invention is: A computer lock includes a lock housing, a sliding member, an operating member, a pair of latches, and a locking mechanism. The sliding member is slidably fitted within the lock housing, and one end of the sliding member is provided with a limiting pin. The operating member is movably fitted with the lock housing and is throttle-connected to the sliding member to drive the sliding member. The latches are symmetrically arranged on both sides of the limiting pin. The inner end of the latch is rotatably connected to the lock housing, and the outer end of the latch is pushed by the limiting pin as the sliding member slides to change the opening and closing angle. The locking mechanism is disposed within the lock housing and is used to lock the operating member.

[0006] The outer end of the limiting shaft is provided with a limiting protrusion; the outer end of the locking tongue is provided with a number of continuously connected steps for the limiting protrusion to move and cooperate.

[0007] Preferably, the side of the limiting shaft is provided with a mating surface that matches the step of the locking tongue, and the mating surface smoothly transitions to the limiting protrusion.

[0008] Preferably, the computer lock further includes an elastic ring fitted around the circumference of the latch; the circumference of the latch is provided with a groove for the elastic ring to be fitted.

[0009] The sliding member has a guide block on its side, and the lock housing has a sliding groove for sliding engagement of the sliding member. The side wall of the sliding groove has a guide groove for sliding engagement of the guide block.

[0010] Preferably, the operating element is a knob that rotates with the lock housing and is coaxially arranged with the sliding element, and its inner end is threadedly connected to the sliding element.

[0011] Preferably, a plurality of locking grooves are provided on the circumferential surface between the two ends of the operating member for the movable end of the locking mechanism to be embedded, and the locking grooves are arranged at equal angular intervals around the axis of the operating member.

[0012] Preferably, the spacing between the steps is linearly corresponding to the rotation angle of the operating component, and the limiting protrusions are sequentially engaged with each step as the operating component rotates by a preset angle.

[0013] The locking mechanism is the pin wheel assembly of a pin wheel combination lock. The pin wheel assembly is installed inside the lock housing and includes a pin wheel shaft that slides within the lock housing, a bushing fitted on the pin wheel shaft, a pin wheel fitted on the bushing, and a locking spring for driving the pin wheel shaft to move axially. The bushing rotates synchronously with the pin wheel and restricts the axial movement of the pin wheel shaft when the pin wheel is not the correct combination. When the axial movement restriction of the pin wheel shaft is released, the locking spring is compressed. The end of the pin wheel shaft abuts against and is embedded in a locking groove provided on the circumference of the operating member under the action of the locking spring.

[0014] Preferably, the locking groove is configured as a V-shaped groove with guide slopes on both sides, and the end of the character wheel shaft is configured as a cone.

[0015] Preferably, the digit wheel assembly further includes a spring plate disposed within the lock housing, the spring plate abutting against the circumferential surface of the digit wheel to achieve the function of preventing the digit wheel from rotating.

[0016] After adopting the above technical solution, the present invention has the following technical effects: When using the computer lock, users can adjust the relative position of the sliding component within the lock housing using the operating mechanism. This, in turn, changes the opening and closing angle of the bolt through the action of the limiting pin. This allows a single computer lock to simultaneously accommodate multiple keyhole sizes, meeting the requirements of adjustable, one-to-many usage and reducing user costs. Simultaneously, the computer lock is equipped with a locking mechanism to lock the operating mechanism. When the lock is in the locked state, the user cannot change the state of the operating mechanism, effectively preventing accidental changes in the bolt opening and closing angle due to accidental activation or external force, ensuring a stable locking effect on electronic devices. Furthermore, the operating mechanism of this invention is directly linked to the sliding component, resulting in fewer parts, easier assembly, and lower cost. Attached Figure Description

Detailed Implementation

[0028] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0029] refer to Figures 1 to 10 As shown, the present invention discloses a computer lock, including a lock housing 10, a sliding member 20, an operating member 30, a pair of locking tongues 40, and a locking mechanism; The sliding member 20 is slidably fitted inside the lock housing 10, and one end of it is provided with a limiting pin 21 that moves out of the lock housing 10. The operating element 30 is movably engaged with the lock housing 10 and is connected to the sliding element 20 in a transmission manner to drive the sliding element 20, thereby changing the relative position of the sliding element 20 within the lock housing 10. The latch 40 is symmetrically arranged on both sides of the limiting pin 21; the inner end of the latch 40 is rotatably connected to the lock housing 10, and the outer end of the latch 40 is pushed by the limiting pin 21 as the sliding member 20 slides to change the opening and closing angle. The locking mechanism is located inside the lock housing 10 and is used to lock the operating component 30.

[0030] Through the above solution, when using the computer lock, the user can adjust the relative position of the sliding member 20 within the lock housing 10 using the operating component 30. This, in turn, changes the opening and closing angle of the bolt 40 through the action of the limiting pin 21. This allows a single computer lock to simultaneously adapt to multiple keyhole sizes, meeting the requirements of adjustable, one-to-many usage and reducing user costs. Simultaneously, the computer lock is equipped with a locking mechanism that can lock the operating component 30, preventing the user from changing the state of the operating component 30 when the lock is in the locked state. This effectively prevents accidental changes in the bolt opening and closing angle due to accidental contact or external force, ensuring a stable locking effect on electronic devices. Furthermore, the operating component 30 of this invention is directly linked to the sliding member 20, resulting in fewer parts, easier assembly, and lower cost.

[0031] The following illustrates specific embodiments of the present invention: The outer end of the aforementioned limiting shaft 21 is provided with a limiting protrusion 22; the outer end of the locking tongue 40 is provided with several continuously connected steps 41 for the limiting protrusion 22 to move and engage. Thus, the multiple steps 41 create a continuous drop between the opposite sides of the locking tongue 40 and the limiting protrusion 22. When the limiting protrusion 22 engages with the steps 41 at different positions as the sliding member 20 slides, the locking tongue 40 will be pushed away from the limiting shaft 21 by the limiting protrusion 22 at different angles (see...). Figures 7 to 10 ).

[0032] Furthermore, the side of the aforementioned limiting shaft 21 is provided with a mating surface 23 that matches the step 41 of the latch 40, and the mating surface 23 smoothly transitions to the limiting protrusion 22. See also... Figure 6 When the lock is in the unlocked state, the bolt 40 can fit tightly against the side of the limiting shaft 21, so that the bolt 40 is closed to the minimum opening angle.

[0033] Meanwhile, the present invention also includes an elastic ring 50 sleeved on the circumferential surface of the latch 40. By providing the elastic ring 50, elasticity is provided so that the latch 40 has a tendency to close when in the locked state (i.e., the latch 40 is open outwards), ensuring that the latch 40 can fit tightly against both sides of the limiting shaft 21, thereby ensuring the stability of the product's opening and closing function. In this embodiment, the circumferential surface of the latch 40 is provided with a groove 42 for the elastic ring 50 to be embedded, ensuring that the elastic ring 50 does not disengage during the opening and closing of the latch 40.

[0034] See above. Figures 7 to 10 Taking the computer lock of the present invention as an example that can adapt to three sizes of keyholes, the step 41 on the surface of the latch 40 includes a first step 41a, a second step 41b, and a latch support surface 41c. The latch support surface 41c is connected to the surface of the latch 40. The first step 41a, the second step 41b, and the latch support surface 41c are connected in sequence. Then the working state of the present invention is as follows: See Figure 7 When the lock is in the unlocked state, the bolt 40 is fully engaged with the side of the limiting shaft 21, at which point the opening angle of the bolt 40 is at its minimum. During the locking process, the limiting shaft 21 retracts under the drive of the operating component 30, causing the bolt 40 to gradually open to the target angle; see [link to relevant documentation]. Figure 8 When the slider 20 / limiting shaft 21 moves to the first position, the limiting protrusion 22 abuts against the first step 41a, opening the latch 40 to the first angle; see also Figure 9 When the slider 20 / limiting shaft 21 continues to move to the second position, the limiting protrusion 22 abuts against the second step 41b, opening the latch 40 to the second angle; see also Figure 10When the slider 20 / limiting shaft 21 continues to move to the third position, the limiting protrusion 22 abuts against the bolt support surface 41c, opening the bolt 40 to the third angle; the first angle, the second angle, and the third angle increase in sequence.

[0035] The sliding member 20 has a guide block 24 on its side, and the lock housing 10 has a sliding groove 11 for sliding engagement of the sliding member 20. The side wall of the sliding groove 11 has a guide groove 12 for sliding engagement of the guide block 24. Through the engagement of the guide block 24 and the guide groove 12, the sliding direction of the sliding member 20 can be guided and its rotation can be prevented. The length of the guide groove 12 can also limit the sliding stroke of the sliding member 20. In this embodiment, guide blocks 24 are provided on both sides of the sliding member 20, and guide grooves 12 are provided on both sides of the sliding groove 11.

[0036] Furthermore, the aforementioned operating element 30 is a knob that rotatably engages with the lock housing 10 and is coaxially arranged with the sliding element 20. Its inner end is provided with a screw 31 that is threadedly connected to the sliding element 20; the inner end of the sliding element 20 is provided with a threaded hole 25 for threaded connection of the screw 31. Thus, when the rotation of the sliding element 20 is restricted, designing the sliding element 20 and the operating element 30 as a threaded connection allows the rotation of the operating element 30 to be converted into linear movement of the sliding element 20, thereby changing the relative position of the sliding element 20 within the lock housing 10. In this embodiment, the outer end of the operating member 30 is provided with a plurality of anti-slip textures 32 to increase the friction when the user rotates the operating member 30, improve the operating feel and convenience, and avoid operation failure due to sweaty hands or slipping; the distance between each step 41 is set to be linearly corresponding to the rotation angle of the operating member 30, that is, linearly corresponding to the thread spacing on the sliding member 20 and the screw 31. Each time the operating member 30 rotates by a specific angle, the limiting protrusion 22 is moved and engaged with each step 41 in sequence through the transmission of the screw 31 and the sliding member 20. Specifically, each time the operating member 30 rotates by one revolution, the limiting protrusion 22 is engaged with the first step 41a, the second step 41b and the locking tongue support surface 41c in sequence.

[0037] Secondly, the circumferential surface between the two ends of the aforementioned operating member 30 is provided with a plurality of locking grooves 33 for the movable end of the locking mechanism to be inserted. The locking grooves 33 are arranged at equal angular intervals around the axis of the operating member 30. Taking the locking mechanism described below as an example, the movable end can be the digit wheel shaft of the digit wheel assembly. When the digit wheel shaft is inserted into one of its locking grooves 33, the operating member 30 can no longer rotate, and therefore the position of the sliding member 20 cannot be changed, thus maintaining the locked / unlocked state of the lock.

[0038] The lock housing 10 includes a first outer shell 10a and a second outer shell 10b that are detachably connected by means of screws or the like, which facilitates the installation of components inside the lock housing 10.

[0039] Regarding the aforementioned locking mechanism, it can generally be either electrically driven or purely mechanically driven. When using an electrically driven mechanism, the locking mechanism can be a motor or solenoid valve located on the side of the operating member 30. The output end of the motor or solenoid valve is equipped with a driveable locking element, such as a slider or metal block. Locking or unlocking the operating member 30 is achieved by driving the slider or metal block to abut against or disengage from the operating member 30.

[0040] The following mainly describes the structural details when using a purely mechanical drive method: Specifically, the locking mechanism described above is the pin wheel assembly 60 of the pin wheel combination lock. The pin wheel assembly 60 is installed inside the lock housing 10 and includes a pin wheel shaft 61 that slides within the lock housing 10, a bushing 62 fitted onto the pin wheel shaft 61, a pin wheel 63 fitted onto the bushing 62, and a locking spring 64 for driving the pin wheel shaft 61 to move axially. The bushing 62 rotates synchronously with the pin wheel 63 and restricts the axial movement of the pin wheel shaft 61 when the pin wheel 63 is not the correct combination. When the axial movement restriction of the pin wheel shaft 61 is released (i.e., when the combination is correct), the locking spring 64 can be compressed. The end of the pin wheel shaft 61 abuts against and locks the circumferential surface of the operating member 30 under the action of the locking spring 64, that is, it is embedded in the locking groove 33 described above. In this embodiment, the locking groove 33 is set as a V-shaped groove with guide slopes on both sides, and the end of the pin wheel shaft 61 is set as a cone. In this way, when the password is correct, the end of the character wheel shaft 61 can be smoothly slid into or out of the locking groove 33 by using the cooperation between the cone head and the V-shaped groove guide slope, thereby improving the smoothness of the mechanical structure and avoiding jamming.

[0041] Furthermore, the aforementioned digit wheel assembly 60 also includes a spring piece 65 disposed within the lock housing 10. The spring piece 65 abuts against the circumferential surface of the digit wheel 63 to achieve the function of preventing the digit wheel 63 from rotating, thereby stopping the digit wheel 63 at the number position after the user has dialed it.

[0042] In the aforementioned character wheel assembly 60, the mating relationship between the character wheel shaft 61, bushing 62, and character wheel 63, as well as the related structural design, are already quite mature existing technologies and will not be elaborated here.

[0043] In this embodiment, the operating component 30 is provided with a screw 31, anti-slip texture 32 and locking groove 33. These parts can be integrally provided on the operating component 30, or the operating component 30 can be designed as a knob part and a rod part, which can be detachably connected. The anti-slip texture 32 is provided on the knob part, and the screw 31 and locking groove 33 are provided on the rod part.

[0044] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
