CN204961533U - Connection structure of box nut on follow -up ware on follow -up ware - Google Patents

Abstract

The utility model provides a connection structure of box nut on follow -up ware on follow -up ware, the box nut passes through the external screw thread and installs on the follow -up ware on the follow -up ware, and the faying face department of box nut and follow -up ware is equipped with at least one along the circumferencial direction and dashes and rivet recess on the follow -up ware. Inject the further of above -mentioned technical scheme: the box nut passes through after the external screw thread installs on the follow -up ware on the follow -up ware, and the outer end of box nut is not higher than the outer terminal surface of mounting hole on the follow -up ware on the follow -up ware. The utility model discloses a dash and to rivet the structure, realize the locking of on follow -up ware box nut, once dash rivet accomplish locking, easy operation, compare the thickness attenuation of box nut on the follow -up ware, weight loss 0.5 -0.6Kg with present connection structure, reduced a part (back of the body jack panel), reduce cost is at least 10 yuan /.

Description

The linkage structure of cap nut on follower on a kind of follower

Technical field

The utility model relates to the linkage structure of cap nut on follower on follower.

Background technique

In current motor turning follower, the linkage structure of cap nut on follower on follower, as shown in Figure 1, Figure 2, Figure 3 shows, on follower, cap nut 1 is arranged on follower 3, locking on the overhanging end being arranged on cap nut 1 on follower by a back tightening nut 2, avoid cap nut 1 on follower to loosen.The shortcoming that this structure exists: union piece is many, cost is high.

Summary of the invention

In order to reduce number of parts, weight reduction, reduce costs, the utility model proposes the linkage structure of cap nut on follower on a kind of follower.

For this reason, the technical solution of the utility model is: the linkage structure of cap nut on follower on a kind of follower, on follower, cap nut is arranged on follower by outside thread, it is characterized in that: on follower, the junction plane place of cap nut and follower is along the circumferential direction provided with at least one and rushes riveting groove.

Further restriction to technique scheme: after cap nut is arranged on follower by outside thread on follower, on follower, the outer end of cap nut is not higher than the exterior edge face of mounting hole on follower.

Further restriction to technique scheme: on follower, the junction plane place of cap nut and follower is along the circumferential direction laid with 3-6 and rushes riveting groove.

Connecting means of the present utility model: cap nut on follower is screwed in follower, and then cap nut and follower junction plane place carry out rushing riveting on follower, destroys cooperation place screw thread, reaches anti-loosing effect.

Beneficial effect: the utility model adopts and rushes riveting knot structure, realizes the locking of cap nut on follower, has once pressed locking, simple to operate; Compared with existing linkage structure, the lower thickness of cap nut on follower, weight saving 0.5-0.6Kg; Decrease a part (back tightening nut), reduce costs at least 10 yuan/part.

Fig. 5 is along A-A sectional view in Fig. 4.

Fig. 6 is the long splice composition of cap nut on follower on a kind of follower of the utility model.

Fig. 7 is the partial enlarged drawing rushing riveting groove in Fig. 6.

Embodiment

As shown in figs. 4-7, the linkage structure of cap nut on follower on a kind of follower, on follower, cap nut 4 is arranged on follower 5 by outside thread, and on follower, the junction plane place of cap nut and follower is along the circumferential direction provided with at least one and rushes riveting groove 6.

As shown in Figure 6, after on follower, cap nut is arranged on follower by outside thread, on follower, the outer end of cap nut is not higher than the exterior edge face of mounting hole on follower.Thus, on the follower in the utility model, cap nut 4 is than the lower thickness of cap nut 1 on follower of the prior art, thus alleviates weight.

As shown in Figure 6, on follower, the junction plane place of cap nut and follower is along the circumferential direction laid with 3-6 and rushes riveting groove, is the structure optimized like this, namely reaches reliable anti-loosing effect, be convenient to practical operation again.

As shown in Figure 4, Figure 5, cap nut 4 on the follower in the utility model, is provided with loss of weight chamber in exterior edge face, loss of weight is provided with stiffening rib in chamber, further mitigates weight like this on the basis of proof strength.

Claims (3)
