Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, and a kind of lock body that the steel cable lock of sufficient mechanical strength and low cost of manufacture is arranged is provided.

For achieving the above object, the utility model adopts a kind of lock body of steel cable lock, lock body is provided with pin cavity volume and lock core cavity volume, and lock body is made up of lock core cover, lock body sheath, three parts of watch box overcoat, and the lock core cover is made of pin cavity volume that is wholely set and is arranged in parallel and lock core cavity volume; Lock body sheath is provided with ccontaining lock core die cavity cover and both ends open, and the lock core cover constitutes to locate with die cavity on the lock body sheath and cooperates, and is provided with the installing port of fixedlying connected with wirerope at an end of lock body sheath; The watch box overcoat is that the cross section is an annular, with the member that the outer face close neighbour of lock body sheath is provided with and the formation clamping cooperates, one end opening of watch box overcoat, the outer face of watch box overcoat are provided with the pin cavity volume that puts with lock core and the suitable groove of opening on the lock core cavity volume.

Cooperate for lock core cover and lock body sheath can constitute the location, the outer wall that the utility model further is set to the lock core cover is provided with locating flange, forms the locating flange that puts with lock core around the die cavity on lock body sheath and constitutes the step that the location cooperates.

In order to make the assembling of watch box overcoat and lock body sheath firmly, the utility model further is set to openend that watch box puts outward and constitutes to rivet with installing port on the lock body sheath and cooperate.

The utility model just provides a kind of lock body of steel cable lock, with original all-in-one-piece lock body split change, lock body comprises lock core cover, lock body sheath, watch box overcoat, and the lock core cover is made of pin cavity volume that is wholely set and lock core cavity volume, and pin cavity volume opening one side that puts at lock core forms outer rim; Lock body sheath is provided with ccontaining lock core cavity cover and both ends open, forms the outer rim that puts with lock core and constitute the step that the location cooperates around cavity; The watch box overcoat is that the cross section is an annular, with the member that the outer face close neighbour of lock body sheath is provided with and the formation clamping cooperates, one end opening of watch box overcoat, the outer face of watch box overcoat are provided with the pin cavity volume that puts with lock core and the corresponding fluting of opening on the lock core cavity volume.Aborning, the lock core cover is made by Zinc material, lock body sheath is formed by plastic injection-moulded, is equipped with the intensity that watch box overcoat that iron plate makes is strengthened whole lock body in lock body sheath outside, by splitization, reduce the use amount of Zinc material, afterwards reduce the cost of production of lock body, be added in outside the lock body sheath by the watch box overcoat of making by iron plate, stronger compared with original zinc lockmaking body intensity, and three part assemblings are simple, practical.

The specific embodiment

As shown in Figure 5, specific embodiment of the utility model is a kind of lock body 1 of steel cable lock, lock body 1 is made up of lock core cover 11,

lock body sheath

12,13 3 parts of watch box overcoat, and as shown in Figure 1, lock core overlaps 11 and is made of pin cavity volume 2 that is wholely set and is arranged in parallel and lock core cavity volume 3; Pin cavity volume 2 and lock core cavity volume 3 interconnect, and are provided with opening separately, and plug on the wirerope and lock core are separately positioned in pin cavity volume 2 and the lock core cavity volume 3, but and axial rotation; As shown in Figure 2, lock body sheath 12 is provided with ccontaining lock core cover die cavity 121 11 and both ends open, the outer wall of lock core cover 11 is provided with locating flange, locate the step that cooperates in formation around the die cavity on the lock body sheath 12 121 with the locating flange formation on the lock core cover 11, end at lock body sheath 12 is provided with the installing port 122 of fixedlying connected with wirerope, and the fixing head of wirerope just is located in the installing port 122; Shown in Fig. 3,4, watch box overcoat 13 is that the cross section is an annular, with the member that the outer face close neighbour of lock body sheath 12 is provided with and the formation clamping cooperates, one end opening of watch box overcoat 13, the outer face of watch box overcoat 13 be provided with lock core cover 11 on pin cavity volume 2 and the suitable groove 131 of the opening on the lock core cavity volume 3, the openend on the watch box overcoat 13 constitutes to rivet with installing port 122 on the lock body sheath 12 and cooperates.
