Description

Technical field

[0001] The invention relates to a lock suitable for different slots for electronic devices, in particular a lock suitable for different slot sizes for electronic devices. State of the art

[0002] When using electronic devices like laptops in public places, it's not just about data security, but also about physical protection against theft when the device needs to be temporarily set down to get food or use the restroom. While most electronic devices, such as laptops, have a slot, the size of the slot varies depending on the brand and model. Therefore, a single lock won't fit all of a user's electronic devices. This necessitates the purchase of multiple locks with different specifications, resulting in high acquisition costs. A lock that fits various slot sizes is therefore desirable. Such locks would undoubtedly increase user willingness to buy and reduce the likelihood of returns due to non-compliant specifications. Object of the invention

[0003] The invention is based on the objective of creating a lock for electronic devices that is suitable for different slots and can be used with slots of different sizes. Technical solution

[0004] This problem is solved according to the invention by a lock for electronic devices suitable for different slots, having the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

[0005] The invention provides a lock for electronic devices suitable for different slots, which is used to lock an electronic device and unlocked with a key. The lock for electronic devices has a housing composed of two housing units, the housing being externally connected to a safety cable to fix the lock in place. Inside the housing are a first receiving chamber and a second receiving chamber, with a first separating part projecting from the bottom of the first receiving chamber and a second separating part projecting from the upper part of the second receiving chamber, and a keyhole being arranged in the second receiving chamber that passes through the bottom of the second receiving chamber.A third receiving chamber is arranged between the first and second separating parts. A slide is located in this chamber, through which a through-opening passes. A first spring is arranged between the slide and the housing. A locking element is rotatably mounted next to the first receiving chamber, with at least one sawtooth-shaped first locking edge projecting from it. A second spring is arranged between the locking element and the housing. A locking cylinder is mounted in the second receiving chamber. A cylinder shaft is rotatably mounted in the center of the cylinder shaft. A flange is arranged in the central section of the cylinder shaft such that it projects outwards. The central section of the cylinder shaft is inserted through the through-opening such that the flange is located within the through-opening.In the first receiving chamber, a locking element is arranged, which is fitted over the lock cylinder. A plurality of sawtooth-shaped secondary locking edges project from the surface of the locking element, and a third spring is arranged between the locking element and the first separating element. When the first and second locking edges are engaged, the locking element can only move downwards. As the locking element moves downwards, the first and second locking edges temporarily disengage. When the locking element moves upwards, the engagement structure of the first and second locking edges causes a blocking action. A locking head housing is placed on top of the locking element and connected to it, with two locking units rotatably mounted within the locking head housing.When the locking element moves downwards, the cylinder shaft is pressed between the two locking units, forcing them apart. A clamping jaw is located at the front end of each locking unit and is designed to project outwards. The electronic device is equipped with a slot. When the locking units are inserted into the slot so that they push down the locking element, the first locking edge and the second locking edges slide relative to each other and engage, thus moving the locking element into a lower position. This increases the distance between the two locking units until they snap into place in the slot. The clamping jaws then brace against the inside of the slot, preventing the lock for electronic devices from being pulled out.By causing the first and second locking edges to slide and engage further, the locking element is moved further down, increasing the distance between the two locking units. The key can be inserted into the keyhole and then the cylinder shaft rotated. When the cylinder shaft is rotated 90 degrees, the flange is caused to push the slider, which in turn moves the locking element. This disengages the first and second locking edges, allowing the locking element to rebound under the action of the third spring. This pulls the cylinder shaft, located between the two locking units, out, reducing the distance between them and disengaging them from the slot.

[0006] The lock according to the invention for electronic devices is characterized by the following: Due to its structural design, in that the second locking edges on the surface of the locking element and the first locking edge engage in one and the same direction, the locking element can only move downwards, so that the first and second locking edges can temporarily disengage. If the locking element moves in the opposite direction, i.e., upwards, the first and second locking edges will engage firmly, so that the locking element can be moved downwards in stages, allowing the cylinder shaft to be pressed between the two locking units and to gradually push these two locking units apart.This ensures that the clamping jaws are suitable for support on the inside of the slot of different sizes, so that the lock according to the invention can be used flexibly to protect the electronic device with different slot sizes from unauthorized movement.

[0007] The following section will explain in more detail the tasks, features, and advantages of the present invention with reference to a detailed description of an exemplary embodiment and the accompanying drawings. However, the invention is not limited to the description of this exemplary embodiment and its illustration in the accompanying drawings.

[0008] As from Fig. 1 to Fig. As can be seen in Figure 6, the present invention relates to a lock 10 for electronic devices, which is used to lock an electronic device 20 and is unlocked with a key 30. The lock 10 for electronic devices has a housing 11, which is composed of two housing units 111, wherein the housing 11 is externally connected to a safety cable 12 to fix the lock 10 in place. Inside the housing 11, a first receiving chamber 13 and a second receiving chamber 14 are arranged, wherein a first separating part 131 projects from the bottom of the first receiving chamber 13 and a second separating part 141 projects from the upper part of the second receiving chamber 14, wherein a keyhole 142 is arranged on the second receiving chamber 14, which extends through the bottom of the second receiving chamber 14.A third receiving chamber 15 is arranged between the first separating part 13 and the second separating part 14. A slide 151 is arranged in this chamber, through which a through-opening 1511 passes. A first spring 152 is arranged between the slide 151 and the housing 11. A locking element 16 is rotatably mounted next to the first receiving chamber 13, and at least one sawtooth-shaped first locking edge 152 projects from it. A second spring 162 is arranged between the locking element 16 and the housing 11. In the second receiving chamber 14 a locking cylinder 17 is attached, in the center of which a cylinder shaft 171 is rotatably mounted, wherein in the middle section of the cylinder shaft 171 a flange 711 is arranged such that it projects outwards, wherein the middle section of the cylinder shaft 171 is inserted through the through-opening 1511 such that the flange 1711 is located in the through-opening 1511.In the first receiving chamber 13, a locking element 18 is arranged, which is fitted over the locking cylinder 17. A plurality of sawtooth-shaped second locking edges 181 project from the surface of the locking element 18, and a third spring 182 is arranged between the locking element 18 and the first separating element 131. When the first locking edge 161 and the second locking edge 181 are engaged, the locking element 18 can only move downwards. As the locking element 18 moves downwards, the first locking edge 161 and the second locking edge 181 temporarily disengage. When the locking element 18 moves upwards, the engagement structure of the first locking edge 161 and the second locking edge 181 will cause a blocking action. A locking head housing 19 is placed on top of the locking part 18 and connected to it, wherein two locking units 191 are rotatably mounted in the locking head housing 19.When the locking element 18 moves downwards, the cylindrical shaft 171 is pressed between the two locking units 191, thus forcing the two locking units 191 apart. A clamping jaw 1911 is arranged at the front end of each locking unit 191 and is designed to project outwards.

[0009] As in Fig. 7 to Fig. As shown in Figure 9, the electronic device 20 is equipped with a slot 21. When the locking units 191 are inserted into the slot 21 so that they depress the locking element 18, the first locking edge 161 and the second locking edges 181 slide relative to each other and engage, thereby moving the locking element 18 into a lower position. This increases the distance between the two locking units 19 so that the two locking units 19 snap into the slot 21. Now the clamping jaws 1911 are supported on the inside of the slot 21 so that the lock 10 for electronic devices cannot be pulled out. As the first locking edge 161 and the second locking edge 181 slide and engage further, the locking element 18 is moved further into a lower position to increase the distance between the two locking units 191.

[0010] As in Fig. 10 and Fig. As shown in Figure 11, the key 30 can be inserted into the keyhole 142 and then the cylinder shaft 171 can be rotated. When the cylinder shaft 171 is rotated 90 degrees, the flange 151 is caused to push the slide 151, which in turn pushes the locking element 16. This disengages the first locking edge 161 and the second locking edge 181, causing the locking element 18 to rebound under the action of the third spring 182. This pulls out the cylinder shaft 171, which is located between the two locking units 191, thereby reducing the distance between the two locking units 191 and disengaging the two locking units 191 from the slot 21.

[0011] To insert the lock according to the invention, the user places the lock head housing 19 against the electronic device 20 and slides it to press the locking element 18 downwards so that the first locking edge 161 and the second locking edges 181 move relative to each other and then engage with one another. This brings the locking element 18 downwards, causing the cylinder shaft 171 to be pressed between the two locking units 191, thus pushing the two locking units 191 apart. This increases the distance between the two locking units 191, and the two locking units 191 engage in the slot 21. Now the clamping jaws 1911 are supported on the inside of the slot 21 in such a way that the lock 10s for electronic devices cannot be pulled out.By causing the first and second locking edges to slide and engage further, the locking element is moved further downwards, thereby increasing the distance between the two locking units. If the slot 21 is so large that the aforementioned distance between the two locking units 191 is too small for the clamping jaws 1911 to securely rest against the inside of the slot 21, the locking head housing 19 can be pushed further to press the locking element 18 downwards to such an extent that the first locking edge 161 and the second locking edges 181 shift relative to each other and then engage with one another to move the locking element 18 further downwards.This causes the cylinder shaft 171 to be pressed further between the two locking units 191, thus pushing the two locking units 191 further apart until the clamping jaws 1911 are supported on the inside of the slot 21 in such a way that the lock 10 cannot be removed. When the cylinder shaft 171 is turned with the key 30, the flange 1711 is caused to push the slide 151 so that the locking element 16 is pushed through the slide 151. This disengages the first locking edge 161 from the second locking edge 181. In addition, the locking element 18 rebounds under the influence of the third spring 182, pulling the cylinder shaft 171 out of the two locking units 191, thus reducing the distance between the two locking units 191 and unlocking the lock 10.By turning the cylinder shaft 171 back with the key 30, the slide 151 rebounds under the action of the first spring 152 and the locking element 15 rebounds under the action of the second spring 162.

[0012] The lock 10 according to the invention for electronic devices is characterized by the following. Due to its structural design, in that the second locking edges 181 on the surface of the locking part 18 and the first locking edge 161 engage in one and the same direction, the locking part 18 can only move downwards, so that the first locking edge 161 and the second locking edge 181 can temporarily disengage. If the locking part 18 moves in the opposite direction, i.e., upwards, the first locking edge 161 and the second locking edge 181 will engage firmly, so that the locking part 18 can be moved downwards in stages, so that the cylinder shaft 171 is pressed between the two locking units 191 and these two locking units 191 are pushed apart in stages.This ensures that the clamping jaws 1911 are suitable for support on the inside of the slot 21 of different sizes, so that the lock 10 according to the invention can be used flexibly to protect the electronic device 20 with different slot sizes from unauthorized movement.

[0013] As in Fig. As shown in Figure 12, the locking part 18 is rotatably arranged relative to the housing 11, so that the locking head housing 19 can be rotated by rotating the locking part 18 in order to adjust the direction of the two locking units 191.

[0014] As in Fig. As shown in Figure 2, an elastic clamp 192 is arranged between the two locking units 191, which is designed to elastically pull the two locking units 191 together after the cylinder shaft 171 has been pulled out of the two locking units 191, so that the distance between the two locking units 191 is reduced.

[0015] As in Fig. As shown in Figure 2, a locking head cover 193 is arranged on the upper part of the locking head housing 19, on which a strip-shaped opening 1931 is arranged, which passes through the locking head cover 193, wherein the two locking units 191 are inserted through the opening 1931 in such a way that they protrude from the surface of the locking head cover 193.

[0016] Although the present invention has been described in detail with reference to an exemplary embodiment, it is obvious to those skilled in the art that the invention is not limited to this embodiment, but rather that modifications are possible such that individual features can be omitted or different combinations of features can be implemented, as long as the scope of protection of the appended claims is not exceeded. The disclosure of the present invention includes all combinations of the individual features presented.
