[Technical Field]

[0001] The present invention relates to an anti-theft lock for electrical appliances that can be applied to different keyholes, and more particularly to an anti-theft lock for electrical appliances that can be applied to different keyholes. [Background technology]

[0002] Until now, in addition to information security, when using electronic devices such as laptops in public places, it is necessary to temporarily leave the device behind to eat, use the restroom, etc., and there is a need to prevent physical theft. Most electronic devices, such as laptops, have a locking hole on the body that can be used to lock them with a lock, but the size of the locking hole varies depending on the brand and model of the device, so an electronic device theft prevention lock cannot be used to lock all the electronic devices you own, and you have to purchase electronic device theft prevention locks with different specifications, which is a waste of money. If a single electronic device theft prevention lock could be used with various different keyholes, it would increase user purchase motivation and reduce the likelihood of users returning the device if it did not fit their specifications.

[0003] Therefore, the inventor took this into consideration, came up with a creative concept, designed it with many years of experience, and after much discussion, trial testing of samples, and several modifications and improvements, completed the present invention. Summary of the Invention

The position of the locking part is lowered, the gap between the two locking chuck units is widened, and the lock is fitted into the locking holes. The chucks lean against the inside of the locking holes, and the electrical appliance theft prevention lock is pulled outward. After the first retaining edge slides further against the second retaining edge, they are engaged, and the position of the retaining part can be further lowered, widening the gap between the two locking chuck units. The key can be inserted into the keyhole to turn the lock core shaft. When the lock core shaft is turned 90 degrees, the protrusion pushes the push block, which pushes the retainer and separates the first retaining edge from the second retaining edge, and the third spring repels the retaining part, causing the lock core shaft to move out from between the two locking chuck units and the gap is reduced, preventing it from being engaged in the locking hole.

[0006] The main purpose of this invention is as follows: due to the one-sided engagement between the multiple second locking edges on the front of the locking part and the first locking edge, the locking part can only slide downwards relative to the first locking edge. When the first locking edge and the second locking edge are temporarily disengaged and moved in the opposite direction, the first locking edge and the second locking edge are engaged with each other, allowing the locking part to be moved downwards in stages, and the lock core shaft is fitted between the two locking chuck units and pushes them out in stages, thereby ensuring that the chuck can lean against the inside of the locking holes of different sizes and be applied, so that the electrical appliance can be locked freely with the electrical appliance theft prevention lock and prevent it from being stolen.

[0009] In order to better understand and appreciate the objects, features and advantages of the present invention, the following detailed description will be given with reference to the drawings, in which: BRIEF DESCRIPTION OF THE DRAWINGS

[0010] First, as shown in Figures 1 to 6, the present invention provides an electrical appliance theft prevention lock applicable to different keyholes, and includes an electrical appliance theft prevention lock (10), the electrical appliance theft prevention lock (10) is used for an electrical appliance (20), and the electrical appliance theft prevention lock (10) is configured to be unlocked by a key (30), the electrical appliance theft prevention lock (10) has an outer shell (11), the outer shell (11) is combined with two outer shell units (111), a lock wire (12) is combined with the outer shell (11), and the electrical appliance theft prevention lock (11) 0), a first storage room (13) and a second storage room (14) are recessed in the outer shell (11), a first partition (131) is protruding from the bottom of the first storage room (13), a second partition (141) is protruding from the top of the second storage room (14), a keyhole (142) is provided through the bottom of the second storage room (14), a third storage room (15) is recessed between the first partition (131) and the second partition (141), and a push button is provided in the third storage room (15). A lock (151) is provided, the push block (151) has a through hole (1511) passing therethrough, a first spring (152) is provided between the push block (151) and the outer shell (11), a stop (16) is pivotally provided beside the first storage room (13), the stop (16) has at least one first serrated stop edge (161) protruding therefrom, a second spring (162) is provided between the stop (16) and the outer shell (11), a lock core (17) is fixedly provided in the second storage room (14), and the A lock core shaft (171) is pivotally mounted in the central portion of the lock core (17), and a protrusion (1711) is provided protruding outward from the center of the lock core shaft (171), the center of the lock core shaft (171) passes through the through hole (1511), and the protrusion (1711) is located within the through hole (1511). A stopper (18) is provided in the first storage room (13) to fit into the lock core from the outside, and a plurality of serrated second stop edges (181) are provided protruding from the surface of the stopper (18).A third spring (182) is provided between the stopper (18) and the first partition (131), and after the first stopper edge (161) and the second stopper edge (181) are engaged, the stopper (18) can only slide downwards relative to the first stopper edge (161). When the stopper (18) slides upwards, the engagement structure between the first stopper edge (161) and the second stopper edge (181) is in a blocking / locking state, and the stopper (18) is in a locking state. When the locking head casing (19) is assembled, two locking chuck units (191) are pivotally mounted in the locking head casing (19). When the stopper (18) moves down, the lock core shaft (171) is fitted between the two locking chuck units (191) and pushes them outward. At the front end of each locking chuck unit (191), a chuck (1911) is protruded outward. As shown in Figures 7 to 9, a locking hole (21) is provided in the electrical appliance (20), and the locking chuck units (191) are pivotally mounted. The locking chuck (191) is inserted into the locking hole (21), and the stopper (18) is pressed down, causing the first stopper edge (161) to slide relative to the second stopper edge (181), and then the stopper (18) is lowered, the gap between the two locking chuck units (191) is widened, and the locking chuck (1911) is fitted into the locking hole (21), and the chuck (1911) rests against the inside of the locking hole (21), and the electrical appliance removal prevention lock (10) can be removed. After the first retaining edge (161) is further slid with the second retaining edge (181), they are fitted together, the position of the retaining portion (18) can be further lowered, and the distance between the two locking chuck units (191) can be enlarged. As shown in Figures 10 and 11, the key (30) can be inserted into the keyhole (142) to turn the lock core shaft (171). When the lock core shaft (171) is turned 90 degrees, the protrusion (1711) pushes the push block (151),The stopper (16) is pushed and moved away from the engagement between the first stop edge (161) and the second stop edge (181), and the stopper portion (18) is repelled by the third spring (182), causing the lock core shaft (171) to move out from between the two locking chuck units (191), and as the gap between them narrows, it is no longer fitted into the locking hole (21).

[0011] In actual use, the lock head casing (19) is attached to the electrical appliance (20), and the lock head casing (19) is pressed to push down the stopper (18). This causes the first stopper edge (161) to slide relative to the second stopper edge (181) and then to be fitted in place. The lock core shaft (171) is fitted between the two locking chuck units (191), pushing them outward and widening the gap between the two locking chuck units (191), thereby closing the locking chuck units (191). When the locking hole (21) is inserted into the locking hole (21), the chuck (1911) leans against the inside of the locking hole (21), making it impossible to remove the electrical appliance removal prevention lock (10). If the locking hole (21) is larger and the distance between the two locking chuck units (191) is too narrow, the chuck (1911) cannot lean against the inside of the locking hole (21), so that the lock head casing (19) can be further pressed to further press down the stopper (18), and the first stopper element (19) cannot be removed. After sliding the edge (161) relative to the second locking edge (181), it is in a fitted state, and the position of the locking portion (18) is further lowered, and the lock core shaft (171) is further fitted between the two locking chuck units (191) and pushes them outward, widening the gap between the two locking chuck units (191), so that the chuck (1911) leans against the inside of the locking hole (21), and the electrical appliance removal prevention lock (10) can be pulled outward. When the lock core shaft (171) is turned using the key (30) until it can no longer be locked, the protrusion (1711) pushes the push block (151), so that the stopper (16) is pushed and moved, causing the first stop edge (161) and the second stop edge (181) to move away from their meshed state, and the third spring (182) repels the stopper (18), causing the lock core shaft (171) to move out from between the two locking chuck units (191), shortening the gap and thus achieving an unlocked state.When the key (30) is turned in the opposite direction on the lock core shaft (171), the first spring (152) repels the push block (151), and the second spring (162) repels the stopper (16).

[0012] Due to the above structure, the plurality of second retaining edges (181) on the front of the retaining portion (18) are engaged with the first retaining edge (161) in one direction, so that the retaining portion (18) can only slide downwards. Therefore, when the engagement between the first retaining edge (161) and the second retaining edge (181) is temporarily released and the retaining portion (18) is moved in the opposite direction, the first retaining edge (161) and the second retaining edge (181) are engaged with each other, so that the retaining portion (18) can slide downwards. (18) can be moved down step by step, and the lock core shaft (171) is fitted between the two locking chuck units (191) and pushes them out step by step, so that the chuck (1911) can lean against the inside of the locking holes (21) of different sizes and can be applied, so that the electrical appliance (20) can be locked freely with the electrical appliance theft prevention lock (10) and it can be prevented from being stolen.

[0013] As shown in FIG. 12, the present invention provides an electrical appliance theft prevention lock that is applicable to different keyholes, and the stopper (18) can rotate relative to the outer shell (11), allowing the lock head casing (19) to rotate together and adjust the direction of the two locking chuck units (191).

[0014] As shown in FIG. 2, the present invention provides an electrical appliance theft prevention lock that is applicable to different keyholes, and an elastic bundle ring (192) having elasticity is provided between the two locking chuck units (191), which is used to reduce the distance between the two locking chuck units (191) by elastic force when the lock core shaft (171) is pulled out from between the two locking chuck units (191).

[0015] As shown in FIG. 2, the present invention provides an electrical appliance theft prevention lock that is applicable to different keyholes, and a lock head cap (193) is provided on the top of the lock head casing (19), the lock head cap (193) has a linear through hole (1931) passing through it, and the two locking chuck units (191) protrude from the surface of the lock head cap (193) through the through hole (1931).

[0016] The above is merely one embodiment of the present invention, and is not intended to limit the scope of the present invention, and any changes or modifications made within the scope of the claims of the present invention should also fall within the scope of the present invention.
