Abstract

This utility model discloses a combination lock which includes a lock core and a lock tube. The lock tube includes an internal lock tube and an external lock tube components mutually fixed together, and the external lock tube component enwraps the internal lock tube tightly. The external lock tube includes an upper lock tube and a lower lock tube combined and fixed together, and a connector is installed at the solid lock position and in the middle of the external lock tube component. The external lock tube component and the internal lock tube are located and fixed by screws or rivets. This utility model designs the common copper lock into a combination lock and replaces the material of the external lock tube component and strengthens its endurance. For example, low carbon ferrous metal material is used to make the external lock tube component, and a connector is installed at the solid lock position in the middle of the external lock tube component which strengthens the whole anti-fold capability of the combination lock-head, therefor realizing the double beneficial effects of controlling the material cost and strengthening the anti-fold capability.

The specific embodiment

Referring to Fig. 1, wherein Fig. 1-1 is the structure chart that just cuing open of the present utility model, and Fig. 1-2 is a left view of the present utility model.As shown in the figure, a kind of Assembled lock comprises lock core 2 and lock pipe, and described lock pipe comprises internal lock pipe 3 fixed with each other and external lock pipe assembly 1, and described external lock pipe assembly 1 tightly wraps up internal lock pipe 3.Be equipped with differential pellet shot from a slingshot, planar marble and spring in described internal lock pipe 3 and the described lock core 2.Described external lock pipe assembly 1 is located, is fixed by screw 5 or rivet 6 with described internal lock pipe 3, also can two kinds of location, fixed forms select simultaneously.

Referring to Fig. 2, Fig. 3 and Fig. 5, wherein Fig. 2-1 for described external lock pipe assembly 1 partly cut open structure chart, Fig. 2-2 is the left view of described external lock pipe assembly 1; Fig. 3-1 is described lock pipe 7 partly cut open structure chart, Fig. 3-2 is described pipe 7 left views of locking; The described lower lock tube 8 of Fig. 5-1 partly cut open structure chart, Fig. 5-2 is described lower lock tube 8 left views.As Fig. 2, Fig. 3 and shown in Figure 5, described external lock pipe assembly 1 comprises combination, lock pipe 7 and the lower lock tube 8 that are fixed together.In the practical operation, available spot welding is with the two welding, fixing.

Referring to Fig. 4, wherein Fig. 4-1 is the elevation of described connector 9, the left view of the described connector 9 of Fig. 4-2.As Fig. 1, Fig. 2, shown in Figure 4, middle, the solid lock position of described external lock pipe assembly 1 is provided with its connector that is fixed together 9.Described connector 9 can be used to strengthen described external lock pipe assembly 1 on the one hand and prevent that it is destroyed, twists off, on the other hand since the tapered end staple pass therethrough, by described connector 9 can be better fixing tapered end.Described connector 9 can be fixed together by spot welding with described external lock pipe assembly 1.

Actual material is selected in the process, and described external lock pipe assembly 1 and/or connector 9 can be made by low carbon black non-ferrous metal sheet material, and described lock core 2 and internal lock pipe 3 are made by copper product, kirsite or other high strength nonmetals.Thereby replace original intensity difference and valuable relatively copper material with cheap and the high material of intensity, do not influence the matching of lockset simultaneously again, realized that material is optional, the beneficial effect of controllable intensity.
