Abstract

The invention discloses a butterfly lock which comprises a master lock and an auxiliary lock, wherein a spring and a lock core are arranged on the master lock; two grooves I are arranged at both sides of the master lock; a groove II is arranged between the two grooves I; the depth of the groove II is more than the depth of the grooves I; the front surface of the groove II is closed to arrange the lock core; the spring passes through the structure edge of the groove II and is fixed in the groove II; the lock core is fixed on the spring; and a lock latch of the lock core latches the master lock and the auxiliary lock together. Two levels of grooves (grooves I and groove II) are arranged on the master lock of the butterfly lock provided by the invention, thus not only the aesthetic property is increased, but also the safety factor is increased; an accident that the spring scratches people can not occur; and a base structure in the traditional structure is not provided, thereby simplifying the manufacturing process and reducing the product cost.

Description

A kind of butterfly lock

Technical field

The present invention relates to field of lockset, specifically a kind of butterfly lock.

Background technology

Butterfly lock is mainly used in case and bag, comprises aviation case, light sound equipment case, plastic uptake case, rotational moulding case etc., and this lock is firm, convenient, and the scope of application is extensive.Butterfly lock of the prior art is made up of 5 parts such as main lock 1, secondary lock 2, spring 3, lock core 4 and bases 5, base utilizes three nest nails to be fixed on the long limit, spring passes base and is fixed on the base, lock core is fixed on the spring, and lock core can fasten secondary lock by rotary handle and realize the snap close function.

But butterfly lock of the prior art has following shortcoming:

(1) adopts the understructure fixing spring, easy scratch user's hand in the use;

(2) adopt the understructure fixing spring, make the engineering complexity, cost is higher;

(3) because spring is fixed by base, and spring is exposed to the outside, influence attractive in appearancely, safety factor is not high.

Summary of the invention

Be to solve the problem that prior art exists, the invention provides a kind of attractive in appearance, safety factor is high, the butterfly lock that reduces cost.

The present invention is achieved in that

A kind of butterfly lock comprises main lock and secondary lock, and described master locks spring and lock core are set,

Described main lock both sides are provided with groove I, be groove II between two groove I, the degree of depth of groove II is greater than the degree of depth of groove I, and the positive face closure of groove II is used for being provided with lock core, the structure limit that described spring passes groove II is fixed in the groove II, and described lock core is fixed on the spring;

The snap close of lock core will be led lock and secondary snap close is connected together.

The groove of sinking optionally, is set on the position of corresponding main lock groove I of described secondary lock and groove II.

Optionally, described main lock and secondary lock junction are respectively arranged with the fin that is higher than main lock seaming.

Butterfly lock provided by the invention has the following advantages:

(1) lock the groove (groove I and groove II) that two levels are set main, spring passes the structure limit of groove II, spring is hidden in the back of main lock, make spring can not expose, not only improved aesthetic property, and improved safety factor, the accident of spring with people's scratch can not take place;

(2) do not have understructure in the traditional structure, the convenient use is difficult for hurting the user;

(3) do not have understructure in the traditional structure, simplify and make engineering, reduce product cost.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, does not constitute to improper qualification of the present invention, in the accompanying drawings:

Fig. 1 is the front view of butterfly lock in the prior art;

Fig. 2 is the rear elevation of butterfly lock in the prior art;

The front view of the butterfly lock that Fig. 3 embodiment of the invention provides;

Fig. 4 is the rear elevation of butterfly lock among Fig. 3;

Fig. 5 is the right view of butterfly lock among Fig. 3;

The specific embodiment

Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.

Shown in Fig. 3～7, the butterfly lock that present embodiment provides comprises main lock 1 and secondary lock 2, on the described main lock 1 spring 3 and lock core 4 is set,

Main lock both sides are provided with groove I 101, be groove II 102 between two groove I 101, the degree of depth of groove II 102 is greater than the degree of depth of groove I 101, the positive face closure of groove II is used for being provided with lock core 4, and the structure limit that spring 3 passes groove II is fixed in the groove II 102, and lock core 4 is fixed on the spring 3, a spring part is hidden in the groove II like this, effect attractive in appearance promptly in the space between groove I and groove II, is played in the back that a part is hidden in main lock, has also avoided the scuffing user;

The snap close of lock core will lead lock 1 and secondary lock 2 snaps together.

For attractive in appearance, also for make the winner lock 1 and secondary lock 2 seem to become one, the groove 201 and 202 of sinking can be set on the position of secondary lock 2 corresponding main lock groove I and groove II, reeded existence simultaneously also can make things convenient for the user to operate snap close.

In addition, say that for convenience main lock and secondary lock are installed on the case and bag or on other carriers, can be respectively arranged with the fin 5 that is higher than main lock seaming at main lock and secondary lock junction.

More than the technical scheme that the embodiment of the invention provided is described in detail, used specific case herein the principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
