Detailed Description

The utility model discloses a tool to lock is used for electron device, supplies to be connected with electron device's lockhole. The electronic device is preferably portable, such as but not limited to a notebook computer, a tablet computer, a mobile phone, an electronic book, a digital photo frame, a GPS navigation machine, a mobile network device, a PDA, a digital walkman, an electronic dictionary, etc.

As shown in fig. 1A to 2B, the lock 800 of the present invention includes a housing 100, a rotary hook 200, a driving device 300, and a lock body 400. The housing 100 has a front opening 110 at one end. The rotary hook 200 is disposed in the housing 100 to be rotatable with respect to the housing 100. In this embodiment, the rotating hook 200 is disposed in the housing 100, can rotate relative to the housing 100 along a plane parallel to the X-Y plane, and is in the shape of a scissors. However, in different embodiments, the number of the rotating hooks 200 may be two or more, at least one of which can rotate relative to the housing 100 along a plane parallel to the X-Y plane, and is not limited to be scissors-shaped. The rotating hook 200 includes a front end 210 and a rear end 220, the front end 210 at least partially protrudes out of the front opening 110, and the end of the front end 210 has a hook 211 extending laterally. The rear end portion 220 extends in a direction opposite to the front end portion 210. Wherein the X, Y, and Z axes are orthogonal.

As shown in fig. 2A and 2B, the driving device 300 includes a force application member 330, a first driving member 310, and a second driving member 320. The force applying member 330 includes a force receiving portion 331 disposed outside the housing 100 and a force applying portion 332 disposed inside the housing 100, wherein the force receiving portion 331 and the force applying portion 332 penetrate through the housing 100 and are capable of rotating in a linked manner relative to the housing 100. More specifically, in the embodiment shown in fig. 2A, the housing 100 has the driving device opening 120, and the force receiving portion 331 and the force applying portion 332 are connected through the housing 100 via the driving device opening 120.

As shown in fig. 1A to 2B, the first driving member 310 is disposed in the housing 100 and rotates in conjunction with the biasing portion 332. A lock body 400 is provided in the housing 100, and the lock body 400 restricts the movement of the driving device 300 when the lock body 400 is locked. More specifically, as shown in the embodiment of fig. 3A and 3B, the biasing portion 332 is a disk having a plurality of protrusions 333 disposed on a periphery thereof, the first driving member 310 is a gear, and the protrusions 333 are engageable with the gear teeth 311. By the abutment between the protruding member 333 and the gear, when the force application portion 332 rotates along a plane parallel to the X-Y plane, the first driving member 310 can rotate along a plane parallel to the X-Z plane. The lock body 400 includes a lock bar 410, and when the lock body 400 is locked, one end of the lock bar 410 is moved in the Y-axis direction to protrude into the tooth groove 311 of the first driving member 310 to restrict the rotation of the first driving member 310, thereby restricting the movement of the driving device 300. In this embodiment, the lock body 400 is a keyed lock used in conjunction with a key 900. However, in a different embodiment as shown in figure 3C, the lock body 400 may be a different type of lock, such as a combination lock.

As shown in fig. 2A and 2B, the second driving member 320 is disposed in the housing 100 and rotates in conjunction with the first driving member 310 to selectively move the position, so as to change the width of the opening of the front end portion 210. In this embodiment, the first driving member 310 has a driving hole 312, and one end 322 of the second driving member 320 is engaged with the driving hole 312 in a manner of moving along the Y-axis direction, so that the second driving member 320 and the first driving member 310 rotate in a linkage manner. More specifically, the driving hole 312 is a polygonal hole, and one end 322 of the second driving member 320 is a polygonal cylinder with an external contour matching the polygonal hole, so that when the one end 322 of the second driving member 320 is inserted into the driving hole 312, a locking effect is generated on the X-Z plane, so that the second driving member 320 and the first driving member 310 can rotate in a linkage manner, but no locking effect is generated in the Y-axis direction, and the second driving member 320 and the first driving member 310 can move relatively.

Further, as shown in fig. 4A to 4C, the housing 100 has a receiving space 140 extending along the Y axis, and a sidewall thread 144 is disposed on a sidewall of the receiving space 140. The second driving member 320 is disposed in the accommodating space 140, and the second driving member 320 is a cylinder having a driving member thread 324 on a side surface thereof matching with the sidewall thread 144. By the abutting action between the sidewall screw 144 and the driver screw 324, when the first driver 310 rotates, the second driver 320 rotates in conjunction with the first driver, so that the second driver 320 moves toward one end 321 of the rear end 220 along the Y-axis direction to extend into the space between the rear end 220 and the different depth. Wherein, one end 321 of the second driving member 320 facing the rear end portion 220 has a slope, which facilitates the end 321 to move along the Y-axis direction to extend into a position between different depths of the rear end portion 220 and to prop open the rear end portion 220. The lock 800 further includes an elastic member 500, such as a rubber ring, for providing elastic force to bring the rear ends 220 close to each other.

As shown in fig. 5A, the user can first rotate the force-receiving portion 331 in a direction (see fig. 2A), so that the second driving member 320 moves toward the end 321 of the rear end portion 220 along the Y-axis direction to exit between the rear end portions 220. At this time, the rear end portions 220 may approach each other by the elastic force of the elastic member 500, thereby reducing the width of the front end portion 210 to be expanded for insertion into the locking hole 720. In the embodiment shown in fig. 5B, after the front end 210 is inserted into the locking hole 720, the user can rotate the force-receiving portion 331 in the opposite direction, so that the second driving member 320 moves toward the end 321 of the rear end 220 along the Y-axis direction to partially extend between the rear ends 220. Therefore, the rear end portions 220 can be separated from each other, so that the width of the front end portion 210 is increased to engage with the locking hole 720. At this time, the user can further operate to lock the lock body 400 (see fig. 2A) to fix the front end portion 210, so as to achieve the locking effect. In another embodiment as shown in fig. 5C, after the front end 210 is inserted into the locking hole 710, the user can rotate the force-receiving portion 331 in the opposite direction to move the second driving member 320 toward the end 321 of the rear end 220 along the Y-axis direction to extend between the rear ends 220 to a greater extent. At this time, the rear end portions 220 may be further apart from each other, so that the width of the front end portion 210 is further increased to engage with the larger lock hole 710. Then, the user can further operate the lock body 400 to achieve the locking effect.

Viewed from different angles, the lock 800 of the present invention utilizes the rotation driving device 300 to achieve the purpose of adjusting the opening width of the rotating hook 200. The force application member 330, the first driving member 310 and the second driving member 320 of the driving device 300 are engaged with each other by using a gear, a thread, etc. so that the opening width of the rotary hook 200 can be controlled according to the degree of rotation, and the rotation is a substantially continuous non-sectional operation, so that the opening width of the rotary hook 200 can be controlled continuously and non-sectionally, and the driving device can be used for lock holes of different sizes, and has better convenience in use.
