Abstract
The utility model provides an anti-loosing apron board lock, comprising a first locking shell and a locking core. The outer edge of a cylindrical body at the head of the locking core extends out a positioning pin in a radial direction. A spring is connected onto the positioning pin and acts on the outer edge of the cylindrical body in the radial direction. An acting block is connected with the positioning pin, and is exposed from the lateral face of a polygonal column body of an end head. The exposed part of the acting block is provided with an inclined surface or an arc-shaped surface. When a key is inserted into the end head and acts on the inclined surface or the arc-shaped surface, the positioning pin is forced to retreat to the cylindrical body. A positioning concave part is arranged on the inner wall of an assembly hole of the locking shell corresponding to the positioning pin, and the distance between the positioning concave part and the end face on which a rod passing hole is arranged is larger than the length of the cylindrical body of the locking core. The anti-loosing apron board lock disclosed by the utility model has the advantages of safety and reliability in use, and convenience for mounting and dismounting.

Summary of the invention
The utility model provides a kind of locking skirtboard lock, and this skirtboard lock connects reliable and convenient to disassembly.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of locking skirtboard lock comprises a lock shell and a lock core; Said lock shell is a hollow cylinder, and an end of hollow cylinder is an assembly opening, and the other end is the rod hole, and assembly opening is communicated with the rod hole; Said lock core is by head and be with externally threaded locking bar to form, and the main body of head is one section cylinder, and a cylindrical end axially links to each other with locking bar, and the cylindrical other end convexes with a termination, and this termination is a polygon cylinder; Under confined state, locking bar inserts from the assembly opening of lock shell, and stretches out from the rod hole, and cylinder cooperates with assembly opening, it is characterized in that:
Said cylindrical outer rim has extended radially out locating dowel pin, is connected with a spring on this locating dowel pin, and action of the spring in cylindrical outer rim radially;
Be connected with an effect piece on the said locating dowel pin; This effect piece exposes from the side of the polygon cylinder of termination; The partial action piece that exposes is provided with inclined-plane or cambered surface, when key inserts the termination and acts on said inclined-plane or cambered surface, forces locating dowel pin to be shunk back to cylinder;
Offer location indentations corresponding to locating dowel pin on the assembly opening inwall of said lock shell, the distance of location indentations end face to place, rod hole is greater than the cylindrical length of lock core.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said locating dowel pin quantity is at least one, and the upwards even or symmetrical distribution in cylindrical week.
2, in the such scheme, said location indentations is hole, skewed slot or the vertical slot of offering on the assembly opening inwall, and the quantity of location indentations is identical with locating dowel pin quantity, and the upwards even or symmetrical distribution in the week of assembly opening inwall.
3, in the such scheme, said location indentations is the circular groove of offering on the assembly opening inwall.
4, in the such scheme, radially offer guide groove corresponding to locating dowel pin along cylinder on the end face of said lock core head.
5, in the such scheme, the effect end of said termination shape and private key is complementary.
6, in the such scheme, the diameter of said assembly opening equals the diameter of lock core head, and the diameter in rod hole is less than the diameter of lock core head.
The utility model principle of work is: during installation, the lock shell is located in first and is fixed in the mounting hole of object, and lock shell nut is spun on outside the lock shell; With first be fixed object be fixed on the lock shell on, the effect end of private key acts on the effect piece of locating dowel pin, the cylinder center that forces locating dowel pin directly to yearn for the lock core head closes up; This moment locking bar is fixed to second and rotates in the mounting hole of object, install finish after, extract private key; At this moment, locating dowel pin is against on the inwall of assembly opening, and spring is in compressive state; Under vibrating state, cooperating gradually between locking bar and locknut, the mounting hole gets loose, and locking bar moves back outside mounting hole; In case when locating dowel pin retreated to the location indentations position, locating dowel pin is the cylindrical motion radially outward of lock core head in the elastic force lower edge of spring reset, at this moment; The locating dowel pin recesses limit that is positioned is lived, and no longer continues to get loose, and is locking bar and farthest gets loose with mounting hole, locknut cooperate.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1, because the utility model uses locating dowel pin to cooperate with location indentations, makes that this connection is more reliable.
2, because the utility model uses private key to cooperate with termination and locating dowel pin on the lock core head, feasible install and remove more convenient.
