Description
Technical Field
A lock, in particular to a clasp lock body.
Background
The existing lock body of the buckle hook lock usually adopts a buckle lock structure, namely a hook-shaped main body and a rotatable lock plate are matched; however, the existing clasp lock structure has the defects of large number of parts, complex assembly relation and precise structure; for the assembly bench worker, the assembly time is long, and the debugging is difficult.
Disclosure of Invention
The invention aims to solve the defects of the prior art and provides a clasp lock body which can realize self-connection through a smart structure.
A self-attaching clasp lock body includes a hook-shaped clasp lock body; the vertical part of the hook-shaped padlock main body is provided with a sliding groove matched with the lock body clamping plate, the upper surface of the sliding groove is provided with a square groove with semicircular notches at two ends, and the semicircular notches are filled with semicircular bosses;
a lock body clamping plate is arranged in the sliding groove; the upper surface of the lock body clamping plate is provided with a limiting boss, and the limiting boss is positioned between the hook-shaped part of the hook-shaped padlock main body and the square groove;
the square groove is internally provided with a limit locking plate with the shape and the size consistent with those of the square groove, the thickness of the limit locking plate is smaller than the depth of the square groove, and the limit locking plate is fixed by an upset pressing plate formed by pressing a semicircular boss;
when the lock body clamping plate slides upwards until the upper end of the lock body clamping plate abuts against the hook-shaped part of the hook-shaped buckling lock main body, the lock body clamping plate and the hook-shaped part of the hook-shaped buckling lock main body form a closed ring, and when the lock body clamping plate moves downwards until the limiting boss on the upper surface of the lock body clamping plate is abutted against the limiting locking plate, the closed ring is completely opened.
In order to save cost and obtain better strength, the lock body clamping plate is a sheet metal part.
In order to save cost, the locking plate is a stamping part.
In order to facilitate pressing and obtain a more ideal shape, the lock body of the lock catch is made of cast zinc.
Considering the deformation of the material and the connection strength after fixing, the height of the semicircular boss is 2.5mm, the thickness of the locking plate is 2mm, and the depth of the square groove is 2.5 mm.
Has the advantages that:
according to the self-connecting clasp lock body, the hook-shaped clasp lock body, the lock body clamping plate and the limiting locking plate are skillfully matched and assembled, so that the use of connecting parts such as screws and films is omitted, and in terms of the overall structure, the limiting locking plate and the upsetting pressing plate limit the lock body clamping plate in a sliding groove in the hook-shaped clasp lock body on one hand, and the limiting locking plate and the limiting boss are matched on the other hand, so that the movement range of the lock body clamping plate in the sliding groove is limited; the necessary functions of the clasp lock body are realized.
In large-scale production and processing process, this from hook lock body of connecting owing to need not install adapting unit additional, its production efficiency can promote greatly, the cost can descend to some extent, and the motion mode of its lock body cardboard is also changed into the orthoscopic by traditional rotation type in addition, can effectually make things convenient for the installation design of all the other parts such as follow-up lock core, has higher meaning to the neotype tool to lock of development.

FIG. 1 is a schematic view of a self-attaching clasp lock body;
1. the hook-shaped lock body 2, the lock body clamping plate 3 and the limiting locking plate.
Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.
A self-attaching clasp lock body includes a hook-shaped clasp lock body; the vertical part of the hook-shaped padlock main body is provided with a sliding groove matched with the lock body clamping plate, the upper surface of the sliding groove is provided with a square groove with semicircular notches at two ends, and the semicircular notches are filled with semicircular bosses;
a lock body clamping plate is arranged in the sliding groove; the upper surface of the lock body clamping plate is provided with a limiting boss, and the limiting boss is positioned between the hook-shaped part of the hook-shaped padlock main body and the square groove;
the square groove is internally provided with a limit locking plate with the shape and the size consistent with those of the square groove, the thickness of the limit locking plate is smaller than the depth of the square groove, and the limit locking plate is fixed by an upset pressing plate formed by pressing a semicircular boss;
when the lock body clamping plate slides upwards until the upper end of the lock body clamping plate abuts against the hook-shaped part of the hook-shaped buckling lock main body, the lock body clamping plate and the hook-shaped part of the hook-shaped buckling lock main body form a closed ring, and when the lock body clamping plate moves downwards until the limiting boss on the upper surface of the lock body clamping plate is abutted against the limiting locking plate, the closed ring is completely opened.
The lock body clamping plate is a sheet metal part.
The locking plate is a stamping part.
The lock body of the lock catch is made of cast zinc.
Specifically, the height of semicircular boss be 2.5mm, the thickness of locking plate is 2mm, the degree of depth of square groove is 2.5 mm.
When the lock is assembled, the lock clamping plate is firstly placed in the sliding groove, and then the limiting locking plate is placed in the square groove with the notches at the two ends; after the initial installation is finished, the cylindrical boss in the notch is pressed into an upset pressing sheet, and the limiting locking plate is clamped in the square groove under the action of the pressing sheet; the assembly step of the lock body is now completed.
Secondly, set up spacing boss with the lock body cardboard, the sliding range of the cardboard of lock body in the spout can be restricted in the cooperation of spacing boss and spacing locking plate.
The self-connecting clasp lock body is ingenious in structure, and on the premise that the necessary operation action of the clasp lock body can be realized, the self-connecting function of the clasp lock body is realized by ingeniously utilizing the mutually matched structural characteristics of the hook-shaped clasp lock body, the lock body clamping plate and the limiting locking plate, so that the use and installation of connecting parts are omitted; the structural stability, the production efficiency and the production cost of the product are improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
