In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides a locking mechanism based on a connecting rod structure, which is simple to operate, can sense whether to lock or not, is not stressed in a locking state and has strong practicability.
In order to achieve the purpose, the utility model adopts the technical scheme that: a locking mechanism based on a connecting rod structure comprises a first locking plate and a second locking plate, wherein an uncovering hinge part is arranged at one end of the first locking plate, one end of the second locking plate is hinged to the middle part of the first locking plate, a main machine front frame hook is arranged at the other end of the second locking plate, and a bent part arranged around the uncovering hinge part is arranged in the middle part of the second locking plate; through the rotation of the first locking plate, the hinge point of the second locking plate and the first locking plate can move to the two sides of the connecting line of the host front frame hook and the uncovering hinge part.
Based on the above, the other end of the first locking plate is inclined outward to form an operation portion.
Based on the above, the portable electronic device further comprises a storage groove, wherein the storage groove is provided with an uncovering connecting mechanism, and the operating portion is stored in the storage groove in a locking state.
Based on the above, the uncovering hinge part and the hinge part of the second locking plate and the first locking plate are hinged through a knurled shaft.
Compared with the prior art, the utility model has substantive characteristics and progress, and concretely, the utility model forms a link mechanism through the first locking plate and the second locking plate, the uncovering hinge part is hinged on the uncovering part, the host front frame hook is used for buckling the host front frame, the bending part is arranged to avoid the uncovering hinge part on one hand, and on the other hand, the two ends of the second locking plate are positioned in front of the uncovering hinge part in a fastening state, and the two ends of the second locking plate are positioned behind the uncovering hinge part in an opening state; when the two ends of the second locking plate and the uncovering hinging part are positioned on the same straight line, the distance between the two ends of the second locking plate is longest, the first locking plate and the second locking plate are in the maximum deformation state, and the first locking plate and the second locking plate can be in the natural state under the locking and opening states, so that the locking state is free of stress, the durability of the locking state is improved, and the locking mechanism has the advantages of being simple in operation, capable of sensing whether the locking is carried out or not, free of stress under the locking state and high in practicability.
Furthermore, the arrangement of the operating part facilitates the rotation of the first locking plate by an operator; the containing groove plays a role in shielding and beautifying.

Fig. 1 is a perspective view showing a use state of a lock mechanism based on a link structure according to the present invention.
Fig. 2 is a plan view showing a state of use of the lock mechanism based on the link structure according to the present invention.
In the figure: 1. opening the cover; 2. a host front frame; 3. a first locking plate; 4. a second locking plate; 5. a receiving groove; 6. a main body; 7. a knurling shaft; 31. an operation section; 32. uncovering the hinge part; 41. a front frame hook of the main machine; 42. a curved portion.
Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments.
As shown in fig. 1 and 2, a locking mechanism based on a link structure includes a first locking plate 3 and a second locking plate 4, wherein an open-cover hinge portion 32 is disposed at one end of the first locking plate 3, one end of the second locking plate 4 is hinged to the middle of the first locking plate 3, the open-cover hinge portion 32 and the hinge portion of the second locking plate 4 and the first locking plate 3 are both hinged through a knurled shaft 7, a mainframe front frame hook 41 is disposed at the other end of the second locking plate 4, and a bending portion 42 disposed around the open-cover hinge portion 32 is disposed at the middle of the second locking plate 4; through the rotation of the first locking plate 3, the hinge point of the second locking plate and the first locking plate can move to the two sides of the connecting line of the host front frame hook and the uncovering hinge part.
The working principle is as follows:
the front of the main body 6 is provided with the cover 1, the front end of the main body 6 is provided with the main body front frame 2, the first locking plate 3 is hinged on the cover 1 by utilizing the cover hinge part 32, the main body front frame hook 41 is used for buckling the main body front frame 2, the first locking plate 3 and the second locking plate 4 form a link mechanism, the second locking plate 4 moves along with the rotation of the first locking plate 3, because when the two ends of the second locking plate 4 and the cover hinge part 32 are positioned on a straight line, the distance between the two ends of the second locking plate 4 is farthest, the deformation of the first locking plate 3 and the deformation of the second locking plate 4 are also largest, in the locking state, the two ends of the second locking plate 4 are positioned in front of the cover hinge part 32, in the opening state, the two ends of the second locking plate 4 are positioned in the cover hinge part 32, so that the cover hinge part is not stressed in the locking state by the design of size, thereby improving durability thereof.
For convenience of operation, the other end of the first locking plate 3 is inclined outwards to form an operation part 31, and an operator can operate the locking device by rotating the first locking plate 3 through the operation part 31; in order to shield the operating portion 31 conveniently, the portable electronic device further comprises a storage groove 5, a cover opening connecting mechanism is arranged on the storage groove 5, and the operating portion 31 is stored in the storage groove 5 in a locking state, so that the portable electronic device is more attractive.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the utility model or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the utility model as defined by the appended claims.
