Abstract

The present invention relates to a locking device for a bottle cap, which has the technical characteristics that the present invention comprises a force lifting rib and a torsion spring, wherein a force lifting arm of the force lifting rib is supported on the bottle cap, both sides of the force lifting arm of the force lifting rib are provided with a pair of force lifting angles, and both sides of the lower end of the force lifting rib are provided with a pair of force pulling hooks; a cambered pull spring matched with a bottle neck is arranged on the torsion spring, the force lifting rib is rotatablely connected with movable rings arranged on both sides of the cambered pull spring by the force pulling hooks, and the torsion spring is rotatablely connected with a shaft hole arranged on the bottle neck by rotating shafts arranged on both sides of the torsion spring. The present invention has the advantage of simple and reasonable structure; furthermore, the bottle cap can be conveniently unlocked and locked without an unlocking device and can be unlocked and locked for many times, the unlocking and locking operation is labor-saving, etc.

Description

A kind of easily opened bottle cap latching system

Technical field

The present invention relates to a kind of bottle cap latching system, the especially a kind of latching system that need not opener can conveniently open bottle cap and locking bottle cap.

Background technology

The bottle cap of existing beer bottle or the bottle cap on the part beverage bottle all must be opened with special tool, if lack special tool, then opening bottle cap relatively wastes time and energy, and easily makes bottleneck cracked, poor stability.At this problem, people have also designed a kind of bottle cap of similar easy-to-draw pot type, and its shortcoming is: 1, processed complex, draw ring draw and open difficulty; 2, can only open, after the unlatching, bottle cap is disposable to be scrapped, and can not lock bottle cap again and seals.

Summary of the invention

Purpose of the present invention just is at the deficiencies in the prior art part, provide a kind of simple in structure, need not can open, lock bottle cap easily by opener, can repeatedly open, lock the bottle cap latching system of bottle cap again.

The present invention is achieved in that and comprises lifting tendon and torsion spring, the load arm of force of this lifting tendon is supported on bottle cap, the both sides of the load arm of force of this lifting tendon form a pair of lifting force angle, the both sides, lower end of lifting tendon form a pair of pulling force hook, this torsion spring is provided with one and pulls spring with the arc of bottleneck coupling, the active ring that lifting tendon is pulled the both sides moulding of spring by pulling force hook and arc is rotationally connected, this torsion spring by its both sides moulding turning cylinder and bottleneck on the axis hole that is provided be rotationally connected.

The present invention can be provided with the cross-drilled hole that the load arm of force for lifting tendon passes at bottle cap.

The present invention, can be on the load arm of force of lifting tendon moulding or bearing pad is set, the planform of bearing pad can be circular, oval, square etc., certainly, does not get rid of other planform.

The present invention can be provided with a groove in the bottle cap lower end, suit one packing ring on this groove, and this packing ring is generally spring washer, has both played the bottle cap sealing effect, can protect bottleneck impaired again.

The present invention owing to adopt said structure, has simple and reasonable for structurely, need not can open, lock bottle cap easily by opener, can repeatedly open, lock bottle cap again, advantage such as opens, locking is laborsaving.

The present invention is further illustrated for following embodiment accompanying drawings.

The specific embodiment

Referring to figs. 1 through Fig. 5, present embodiment 1 comprises lifting tendon 2 and torsion spring 3, the load arm of force 19 of lifting tendon 2 passes the cross-drilled hole 4 that is provided with on the bottle cap 1, be set with packing ring 18 on the groove 17 of bottle cap 1 lower end, the both sides of the load arm of force 19 of lifting tendon 2 form a pair of

lifting force angle

5,6, the both sides, lower end of lifting tendon 2 form a pair of pulling

force hook

7,8, torsion spring 3 is provided with one and pulls spring 10 with the arc of bottleneck 9 coupling, lifting tendon 2 is by pulling

force hook

7,8 with arc pull the active ring 11 of the both sides moulding of

spring

10,12 are rotationally connected, and torsion spring 3 is by the turning cylinder 13 of its both sides moulding, 14 with bottleneck 9 on the axis hole 15 that is provided with, 16 are rotationally connected.

With reference to Fig. 6 to Fig. 8, present embodiment 2 is that the load arm of force 19 downside butt-joints at lifting tendon 2 have bearing pad 20, and this bearing pad is circular bearing pad, and Fig. 7 is the capping view, and Fig. 8 is for opening the bottle cap view.

With reference to Fig. 9 to Figure 11, present embodiment 3 is to be suppressed with bearing pad 21 on the load arm of force 19 of lifting tendon 2, and this bearing pad is oval bearing pad, and Figure 10 is the capping view, and Figure 11 is for opening the bottle cap view.

Installation of the present invention, embodiment 1 with Fig. 1 is an example, with reference to the running condition scheme drawing of Fig. 2, after bottle cap 1, lifting tendon 2, torsion spring 3 assemblings finish, cover upper gasket 18 is aimed at installation to the axis hole 15,16 of setting on the turning
