Abstract

The utility model relates to a wirerope lock head, in particular to a wirerope lock head for vehicles. The utility model is characterized in that a lock brake mechanism comprises a driving pin and a lock brake. The driving pin is vertical to a lock core rotating shaft and is fixed at the lock core rotating shaft to form linkage. The lock brake and the lock core rotating shaft are arranged in parallel, the surface is provided with a segment screw groove, taking the lock core shaft as axes and one end of the driving pin falls into the screw groove to form linkage. The lock brake is arranged by the manner parallel to the rotating shaft without increasing the diameter of a lock casing as well as saving components of a guide mechanism, thereby ensuring very compact structure and easy production and assembly.

Description

A kind of Wire Rope Lock Head

Technical field: the utility model relates to a kind of Wire Rope Lock Head, particularly vehicle steel cable lock.

Background technology: the stop mechanism of traditional steel cable lock is general all by the cam pin on the lock core be located at cooperation between the chute on the stop and make rotatablely moving of lock core become rectilinear motion to break away from plug and open stop, lock core rotating shaft and stop direction of motion vertical mode are provided with, cause the tapered end volume bigger, heavy, consume material, and this structural mechanism complexity, part are more, the guiding mechanism that need be provided with stop slides steadily to guarantee stop, therefore complex structure, production efficiency are not high, and damage easily, application life is not long.

Summary of the invention: the purpose of this utility model is that the deficiency that overcomes for existing technology provides a kind of compact conformation, the strong Wire Rope Lock Head of good, the anti-destructive power of technology assembling.

For the utility model that achieves the above object has been taked following technical solution: Wire Rope Lock Head still comprises plug, lock core, lock housing and stop mechanism, it is characterized in that: stop mechanism comprises trundle and stop, trundle is vertical with the lock core rotating shaft and be fixed in the lock core rotating shaft and constitute interlock, stop and lock core shaft parallel are provided with, it is the helicla flute in axle center with the lock core rotating shaft that the surface is provided with one section, and trundle one end falls into helicla flute movingly and constitutes interlock.

Because stop is to be provided with in the mode with shaft parallel, can be set up in parallel with rotating shaft and do not strengthen the lock housing diameter, and save the part of guiding mechanism, so structure can be very compact, produce and assembling is more prone to.

The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.

Accompanying drawing 1 is the utility model embodiment blocking structure sectional view;

Accompanying drawing 2 is that accompanying drawing 1A-A is to sectional view;

Accompanying drawing 3 is the utility model embodiment unlocking condition structure sectional view;

Accompanying drawing 4 is that accompanying drawing 3B-B is to sectional view.

Specific embodiment: as Fig. 1, Fig. 2 is described, lock housing 1 is cylindrical, one side end face is provided with lock core storage chamber 12 vertically, lock core 13 outer sheathed movingly lock core bases 14 are placed in the lock core storage chamber 12 and by steady pin 9 and are fixed on the lock housing 1, lock core 13 and lock core base 14 length are about half of lock core storage chamber 12 degree of depth, lock core 13 afterbodys are provided with one section less lock core rotating shaft 8 of diameter and are exposed to outside the lock core base 14, the lock housing 1 surperficial other end is provided with radial pins hole 15 near place, lock core storage 12 bottoms, chamber, lock core storage 12 bottoms, chamber offer the square stop hole 16 that is communicated with plug hole 15, the cross section is similarly square stop 4 one ends and inserts movingly wherein, the length of stop 4 slightly is shorter than the distance between lock core 13 bottom surfaces and plug hole 15 walls, lock core rotating shaft 8 ends are arranged with adapter sleeve 7, and in lock core rotating shaft 8, form interlock by trundle 6, be provided with torsion spring 5 between adapter sleeve 7 end faces and lock core storage 12 bottom surfaces, chamber, the force direction of torsion spring 5 makes lock core 13 energy self-returns for the locking direction, trundle 6 ends are higher than adapter sleeve 7 surfaces, paste mutually with stop 4 on adapter sleeve 7 surfaces, it is the helicla flute 11 in axle center with lock core rotating shaft 8 that stop 4 phase veneers are provided with one section, trundle 6 exposes the end and falls into helicla flute 11 movingly, is provided with ejector spring 2 and spring housing 3 in the plug hole 15.

Claims (2)
