Description

Technical Field

[0001] The utility model relates to the field of locks, in particular to a computer lock. Background Art

[0002] In the field of computer password locks, the structure is as shown in the patent number 202021558683.X, and the name is a computer lock. After the password is unlocked, the two lock hooks are unlocked or locked in the lock hole of the computer by closing or separating.

[0003] However, there is a problem with this computer lock, that is, the opening and closing angles of the two lock hooks are uncontrollable. When facing a smaller lock hole, the fixed opening and closing angle cannot fully open the lock hook. In other words, the lever cannot be rotated to the locked position, and the lever block on the shaft cannot enter the position for cooperation with the guide block, which hinders the locking effect achieved by the lever block and the guide block. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a computer lock, which can control the opening and closing angles of the lock hook, thereby solving the problem that the computer lock cannot be applied to a small-sized lock hole.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a computer lock, having a pair of lock hooks and a locking structure, the lock hooks are cross-arranged and rotatably connected, and is characterized in that it also includes a threaded propulsion device, the threaded propulsion device is arranged between the inner ends of the two lock hooks, and rotating the threaded propulsion device will move in the direction between the two inner ends of the lock hooks. After the two inner ends of the lock hooks are opened outward, the corresponding outer ends are also opened outward. In addition, the threaded propulsion device has a rotating wheel, and the locking beam in the locking structure is located in the groove structure of the outer ring of the rotating wheel. After the locking beam is fixed, the locking beam constrains the rotation of the rotating wheel, thereby forming a locked state.

[0006] Furthermore, the threaded advancement device includes a rotating handle, a rotating sleeve, a fixing nut, a pushing piece, and a threaded piece. The rotating handle is fixed at one end of the rotating sleeve, and the rotating wheel is fixed at the other end of the rotating sleeve. Both ends of the threaded piece are respectively inserted into the rotating wheel and the pushing piece. By rotating the rotating handle, the threaded piece in the rotating wheel rotates synchronously. Since the threaded piece is threadedly connected to the fixing nut, and the fixing nut is fixed in the outer shell, the threaded piece rotates and moves toward the locking hook. The pushing piece enters between the inner ends of the two locking hooks, and the two locking hooks are opened outward by squeezing and opening.

[0007] Furthermore, it also includes a shell that encloses the threaded propulsion device, and the rotating handle is located outside the shell.

[0008] Furthermore, it also includes a reset rubber ring. Grooves are provided on the two inner ends of the lock hooks, and the reset rubber ring is sleeved in the grooves on the two inner ends; the reset elastic force of the reset rubber ring forces the two lock hooks to move closer to each other, thereby improving the smoothness of the coordination between the lock hooks.

[0009] Furthermore, the end of the pusher corresponding to the lock hook is a tapered surface, which makes it smoother when entering between the inner ends of the two lock hooks.

[0010] Furthermore, the locking structure includes a code wheel, an inner sleeve, and a spring. The code wheel is sleeved on the inner sleeve, and the inner sleeve is sleeved on the lock beam. A blocking piece is provided on the outer ring of the lock beam. The blocking piece is close to the end of the lock beam that cooperates with the groove structure. The spring is sleeved on the lock hook and is located between the blocking piece and the inner sleeve. A space for the blocking piece to move up and down is formed in the outer shell. In the unlocked state, when the rotating handle is turned, the groove structure will squeeze the lock beam, so that the lock beam moves out of the groove structure along its axial direction. At the same time, the lock beam will squeeze the spring to produce deformation, and then cut into another groove structure. The spring resets, lifts the blocking piece, and drives the lock beam to advance into the groove structure.

[0011] Furthermore, there are multiple paddles corresponding to the password wheel. The outer periphery of the password wheel is divided into multiple digital display areas by card slots. The paddles are made of elastic metal sheets. Each time a digital display area is rotated, the paddles will withdraw from one card slot and switch to another card slot.

[0012] Beneficial effects of the utility model:

[0013] The utility model adopts a rotary propulsion device, in which a rotary wheel is used in conjunction with a lock beam. The rotary propulsion device can move toward the two inner ends of the lock hooks, thereby changing the positions of the inner ends of the two lock hooks and causing the inner ends of the two lock hooks to rotate. After the adjustment is completed, the lock beam is locked and positioned, and the rotation of the rotary wheel is suppressed in the groove structure to achieve the locking result, thereby solving the problem of being unable to be applied to small-sized lock holes.

[0029] The threaded propulsion device 4 includes a rotating handle 41, a rotating sleeve 42, a fixing nut 43, a propulsion member 44, a threaded member 45, and a rotating wheel 46. The rotating handle 41 is fixed to one end of the rotating sleeve 42 and is located outside the housing 1. The rotating wheel 46 is fixed to the other end of the rotating sleeve 42. The two ends of the threaded member 45 are respectively inserted into the rotating wheel 46 and the propulsion member 44. During the adjustment process, the rotating handle 41 is rotated to make the threaded member 45 in the rotating wheel 46 rotate synchronously. Since the threaded member 45 is threadedly connected with the fixing nut 43, and the fixing nut 43 is fixed in the housing 1, the threaded member 45 rotates while moving toward the locking hook 3. The propulsion member 44 enters between the inner ends 3a of the two locking hooks 3, and the two locking hooks 3 are opened outward by squeezing and opening.

[0030] It should be noted that the threaded member 45 can move horizontally to the left and right inside the rotating wheel 46 , and the movement range thereof will not cause the threaded member 45 to be disconnected from the rotating wheel 46 .

[0031] The rotating wheel 46 is used in conjunction with the locking beam 21 in the locking structure 2. The outer ring of the rotating wheel 46 is provided with a plurality of groove structures 46a. The locking beam 21 is always in the groove structure 46a. After the locking beam 21 is fixed, the rotating wheel 46 cannot rotate, forming a locked state.

[0032] Grooves 31 are provided on the two inner ends 3a of the lock hooks 3, and a same reset rubber ring is provided in the groove 31. When the rotating handle 41 is turned to exit the lock, the reset elastic force of the reset rubber ring forces the two lock hooks 3 to move closer to each other, thereby improving the smoothness of the use of the lock hooks 3.

The spring 24 is sleeved on the lock hook 3 and is located between the blocking member 25 and the inner sleeve 23. A space for the blocking member 25 to move up and down is formed in the outer shell 1. In the unlocked state, when the rotating handle 41 is turned, the groove structure 46a will squeeze the lock beam 21, so that the lock beam 21 moves outward from the groove structure 46a along its axial direction. At the same time, the lock beam 21 will squeeze the spring 24 to produce deformation, and when it cuts into another groove structure 46a, the spring 24 resets, lifts up the blocking member 25, and drives the lock beam 21 to advance into the groove structure 46a.

[0035] A plurality of paddles 100 corresponding to the code wheel 22 are provided in the housing 1. The outer periphery of the code wheel 22 is divided into a plurality of digital display areas by card slots. The paddles 100 are made of elastic metal sheets. Each time a digital display area is rotated, the paddles 100 will withdraw from a card slot and switch to another card slot.
