Abstract

The utility model discloses a butterfly lock which comprises a main lock and an auxiliary lock, wherein a spring and a lock core are arranged on the main lock, two grooves I are formed on the two sides of the main lock, a groove II is formed between the two grooves I, the depth of the groove II is greater than that of the grooves I, the front surface of the groove II is closed so as to mount the lock core, the spring passes through the structural edge of the groove II and then is fixed inside the groove II, and the lock core is fixed on the spring; and the main lock and the auxiliary lock are interlocked through the latch of the lock core. With the arrangement of the two-layer grooves (the grooves I and the groove II) on the main lock, the aesthetic property and the safety coefficient of the butterfly lock are improved, people are prevented from being scratched by the spring, the pedestal structure in the prior art is eliminated, the fabrication process is simplified and the product cost is reduced.

Description

A kind of butterfly lock

Technical field

The utility model 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.

The utility model content

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

The utility model 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.

The butterfly lock that the utility model provides 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.

The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.

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