Description

Technical Field

[0001] This invention relates to the field of accessory assembly technology, and in particular to a locking device that can be used to install, fix, and detach mobile phones, tablets, etc. Background Technology

[0002] With the widespread use of mobile phones, people's demand for mobile phone holders is also increasing. For example, mobile phone car holders currently mostly consist of one part of the holder clamped to the car's air conditioning vent or fixed to the car's front platform, while the other part of the holder is installed on the back of the phone. The phone is fixed in place by the cooperation between the two holders, making it convenient to use the phone for reading, navigation, and other operations.

[0003] For example, Chinese patent CN 208750329 U discloses an anti-rotation locking device. Its main technical solution is as follows: An anti-rotation locking device includes a first component and a second component detachably connected to the first component. The first component includes a first body and a protrusion formed on one side of the first body. The side of the first body away from the protrusion has a cavity extending into the interior of the protrusion. A telescopic locking structure is provided within the cavity, with both ends of the telescopic locking structure extending beyond the outer wall of the corresponding protrusion. A locking mechanism for preventing the second component from rotating is provided on the first body. By providing a locking mechanism on the first component, rotation between the first and second components can be effectively prevented. However, although this device can prevent rotation, in actual production, the locking mechanism still suffers from a relatively complex structure and high manufacturing cost. Summary of the Invention

[0004] The purpose of this invention is to provide a locking device with a reasonable structural design and lower operating cost.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a locking device, including a first component and a second component detachably connected to the first component. The first component includes a body and a protrusion formed on the body. A latch lock and a switch lock are provided in the protrusion. One end of the latch lock and the switch lock are connected by an elastic element, and the other end of both extend out of the protrusion. The switch lock includes a stop block disposed in the protrusion, a wedge block connected to the upper part of the stop block and extending out of the protrusion, a protruding part protruding inward for connecting the elastic element, and a pusher part connected to the lower part of the stop block and extending out of the body. Pushing the pusher part can cause the wedge block to retract into the protrusion, thereby separating the first component from the second component.

[0006] Furthermore, the latch lock includes a wedge-shaped block extending outside the protrusion, a connecting block connected to the wedge-shaped block, and a protrusion for connecting the elastic element.

[0007] Furthermore, the protrusion is a frustum shape with a smaller top and a larger bottom, and its symmetrical ends are provided with through holes for the wedge-shaped block to extend out.

[0008] Preferably, the elastic element is a spring.

[0009] Furthermore, the main body is provided with a through groove that connects to the protrusion, and the push handle extends out of the main body through the through groove.

[0010] Furthermore, the second component is provided with a recess that mates with the protrusion, and the left and right ends of the recess are formed with locking portions that mate with the latch lock and the switch lock.

[0011] Furthermore, the lower end face of the locking portion is arc-shaped.

[0012] Furthermore, the first component is connected to a fixing device, and the back of the second component can also be designed with an adhesive part. The fixing device can be a fixing buckle, fixing clip, double-sided tape, or any other device that can fix the first component to the object.

[0013] The locking device of the present invention has a pusher part that extends out of the main body on the switch lock. Pushing the pusher part can easily unlock and separate the first part and the second part. This structural design makes the entire device simple, reasonable, and cheaper to use and manufacture.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, but this does not constitute a limitation on the scope of protection of the present invention.

[0021] The present invention provides a locking device, which is mainly used for connecting a mobile phone to other equipment or objects. It includes a first component 10 and a second component 20 detachably connected to the first component 10. The second component is a mobile phone case or a mobile phone cover or the outer shell of other objects. When connecting a mobile phone to other equipment or objects, the first part 10 can be installed on other devices or objects. For example, to connect a mobile phone to the interior of a car, the first part 10 of the locking device can be installed at the air conditioning vent inside the car. The second part can be removed, and the mobile phone can be placed inside the second part 20, or the second part can be installed or pasted onto the mobile phone. Then, the second part 20 can be connected to the first part 10 to connect the mobile phone to the interior of the car. As another example, to connect a mobile phone to a wall, the first part 10 of the locking device can be installed on the wall, the second part 20 can be removed, and the mobile phone can be placed inside the second part 20. Then, the second part 20 can be connected to the first part 10 to connect the mobile phone to the wall. Of course, the locking device can also be used to connect other objects to other devices or objects, such as for components that can fix power banks, tablet stands, etc.

[0022] See Figures 1-6 As shown, the present invention provides a locking device including a first component 10 and a second component 20 detachably connected to the first component 10. The first component 10 includes a body 11 and a protrusion 12 formed on the body 11. A latch lock 13 and a switch lock 14 are disposed in the protrusion 12. One end of the latch lock 13 and the switch lock 14 are connected by an elastic member 15, and the other end of both extend out of the protrusion 12. Figure 5 As shown, the switch lock 14 includes a stop block 141 disposed in the protrusion, a wedge block 142 connected to the upper part of the stop block 141 and extending out of the protrusion 12, a protruding part 143 for connecting the elastic member 15, and a pusher part 144 connected to the lower part of the stop block 141 and extending out of the body 11. Pushing the pusher part 144 can cause the wedge block 142 to retract into the protrusion 12, thereby separating the first component 10 from the second component 20.

[0023] Specifically, such as Figure 6 As shown, the latch lock 13 includes a second wedge block 131 extending outside the protrusion, a connecting block 132 connected to the wedge block 131, and a protrusion 133 for connecting the elastic member 15.

Its symmetrical ends are provided with through holes 121 for the wedge blocks 131 and 142 to extend out. The connecting block 132 and the stop block 141 are larger than the through holes and are blocked by the through holes, thus being disposed inside the protrusion 12.

[0025] Preferably, the elastic element 15 is a spring, which is readily available, easy to assemble, and low in cost.

[0026] Specifically, in a preferred embodiment of the present invention, the body 11 is provided with a through groove 111 that connects to the protrusion 12, and the pusher 144 extends out of the body 11 through the through groove 111.

[0027] Specifically, in a preferred embodiment of the present invention, the second component 20 is provided with a recess 21 that cooperates with the protrusion 12, and the left and right ends of the recess 21 are formed with locking portions 211 that cooperate with the latch lock 13 and the switch lock 14.

[0028] Specifically, the lower end face of the locking part 211 is arc-shaped. The arc-shaped design is conducive to the engagement of the locking lock 13 and the switch lock 14 with the locking part 211.

[0029] Specifically, the first component 10 can also be connected to a fixing device, and the back of the second component 20 can also be designed with an adhesive. The fixing device can be a fixing buckle, a fixing clip, double-sided tape, or any other device that can fix the first component to the object.

[0030] The locking device of the present invention has a pusher part that extends out of the main body on the switch lock. Pushing the pusher part can easily unlock and separate the first part and the second part. This structural design makes the entire device simple, reasonable, and cheaper to use and manufacture.
