Description

Locking device Technical Field The invention relates to the technical field of accessory combination, in particular to a locking device which can be used for realizing installation, fixation and separation of mobile phones, flat plates and the like. Background Along with the popularization of mobile phones, the demands of people on mobile phone supports are also increasing, for example, mobile phone automobile supports are often used at present, a part of main bodies of the supports are clamped at an air outlet of an automobile air conditioner or fixed on an automobile front platform, and then the other part of main bodies of the supports are arranged on the back of the mobile phone, and the mobile phone is fixed through the cooperation between the two main bodies of the supports, so that the mobile phone is convenient to use for operations such as reading and navigation. For example, chinese patent CN 208750329U discloses an anti-rotation locking device, which mainly adopts the technical scheme that the anti-rotation locking device comprises a first component and a second component detachably connected with the first component, wherein the first component comprises a first body and a protrusion formed on one surface of the first body, one surface of the first body far away from the protrusion is provided with a concave cavity, the concave cavity extends to the inside of the protrusion, a telescopic clamping piece structure is arranged in the concave cavity, two ends of the telescopic clamping piece structure respectively extend out of the corresponding outer wall of the protrusion, and a locking mechanism for preventing the second component from rotating is arranged on the first body. By providing the locking mechanism on the first member, rotation between the first member and the second member can be effectively prevented. However, this device can prevent rotation, but in actual production, the lock mechanism has a problem that the structure is complicated and the manufacturing cost is high. Disclosure of Invention The invention aims to provide a locking device which is reasonable in structural design and lower in use cost. In order to solve the technical problems, the locking device comprises a first component and a second component detachably connected with the first component, wherein the first component comprises a body and a protruding part formed on the body, a snap lock and a switch lock are arranged in the protruding part, one ends of the snap lock and the switch lock are connected through an elastic piece, the other ends of the snap lock and the switch lock extend out of the protruding part, and the switch lock comprises a stop block arranged in the protruding part, a wedge block connected with the upper part of the stop block and extending out of the protruding part, a protruding part protruding inwards and used for being connected with the protruding part of the elastic piece, and a pushing part connected with the lower part of the stop block and extending out of the body, and the wedge block is pushed to retract into the protruding part, so that the first component and the second component are separated. Further, the snap lock comprises a wedge protruding out of the protruding portion, a connecting block connected with the wedge, and a protruding portion for connecting the elastic piece. Further, the protruding portion is in a truncated cone shape with a small upper part and a large lower part, and through holes for the wedge-shaped blocks to extend out are formed in two symmetrical ends of the protruding portion. Preferably, the elastic member is a spring. Further, a through groove connected with the protruding portion is formed in the body, and the pushing hand portion extends out of the body through the through groove. Further, a concave part matched with the convex part is arranged on the second component, and clamping parts matched with the buckle lock and the switch lock are inwards formed at the left end and the right end of the concave part. Further, the lower end face of the end part of the clamping part is arc-shaped. Further, the first component is connected with a fixing device, the back of the second component can be provided with an adhesive piece, and the fixing device can be a fixing buckle, a fixing clamp, a double faced adhesive tape and other devices capable of fixing the first component on an object. According to the locking device, the push handle part extending out of the body is designed on the switch lock, so that the push handle part is pushed to conveniently unlock and separate the first component and the second component, and the whole device is simplified and reasonable in structure and lower in use and production cost.
