Description

Permutation lock for leather briefcases

The utility model relates to a kind of suitcase combination lock, and this combination lock includes a box body and a structure, and a slide block, a Slave Block, a spring, a push button and a group number code wheel are equipped with in its inside.

Past is installed in the buckle structure on the suitcase, mainly contains following several:

1. press-button type suitcase snap close, be for being installed in the convex clip pin thread of suitcase main body, carry out clinching and fix that it fastens, and intensity is not good enough strutted by article and throw off with the recessed box of putting that is installed in the suitcase enclosing cover, cause article to be scattered, cause many puzzlements in the use by the suitcase mouth is in disorder.

2. handing over cassette suitcase snap close, is by two set button bars of the suitcase mouth end blocking that interlock, so that it is fixing that the tight-lipped sealing of suitcase is closed, its plate is thrown off and opened difficultly, and latent green hand refers to locate pain in the time of for a long time, and moist or greasy more the making of hand opened difficulty, therefore not too practicality.

3. spring-gripping type suitcase snap close refers to the used buckle structure of most of at present suitcase especially, and it be that embedded seat engages with fixings of capping upper blocking seat jack on the main body, the promotion of utilization group retaining and produce the bullet disengagement and open; But the block card of embedded seat easily takes place to lose efficacy and often causes structure can't continue to use again, and in addition because the structure opening ways is very easy and noiseless, causes portable or the normal generation of the back of the body formula suitcase situation that is stolen unconsciously, so protective is low and very easily damage.

4. number formula suitcase lockset can be described as and fully does improvement at the major defect of spring-gripping type suitcase snap close, and add further innovation structure; It then is to reach the purpose that opens and closes lockset by the effect of digit wheel, and still, the structural member of this kind number lockset is many, and therefore many puzzlements of the fit on that causes, and part are promptly many few again, cause the firm inadequately of internal construction body, very easily damage.

Therefore, the purpose of this utility model is to provide a kind of suitcase combination lock, and this combination lock can be simplified element, is convenient to assembling and durable use.

The utility model provides a kind of suitcase combination lock, includes structure and box body, is equipped with a slide block, a Slave Block, a spring, a push button and a group number code wheel in its inside, wherein:

Structure be one with box body be the body that cooperatively interacts, it is provided with two guide rods, and offers a caulking groove between two guide rods, and below this caulking groove a top is arranged;

Slave Block has a clamping stagnation key and a trace, and is provided with a boss post in the trace ora terminalis, and offers short slot rearward, and a top is arranged on it;

Slide block is to be configured between two guide rods of Slave Block and structure, one chute wherein is set and one hypotenuse groove is arranged in edge, and at hypotenuse groove back side system one short slot, its chute, hypotenuse groove are placed on the boss post of two guide rods of structure and Slave Block connecting rod piece, also are provided with two protruding tongues are set on a hole and the bottom;

The butt state is formed on top and structure caulking groove top that spring is configured in the Slave Block short slot;

Offer the perforation of an interface and push button on the positive box face of box body;

Push button is to be arranged in the box body interface, and is linked on the hole of slide block, so that pass slide block and Slave Block is moved both vertically;

Digit wheel is on the wheel plate-like C type ring to be set;

After the said elements combination, moving movement by push button control slide block, limit moving of protruding tongue by digit wheel, when push button promotes slide block and Slave Block is moved both vertically, make the clamping stagnation key of Slave Block leave the clasp position of fastener, when unclamping push button, make slide block and Slave Block from horizontal reset by the active force of spring, the clamping stagnation key fastens fastener once again.

Below, again with regard to the architectural feature of the utility model and operation etc., in the mode of conjunction with figs. explanation, record and narrate in detail in after, wherein:

Fig. 1 is the three-dimensional exploded view of the utility model suitcase combination lock;

Fig. 2 is the three-dimensional combination figure of the utility model suitcase combination lock;

Fig. 3 is the operation chart of the utility model suitcase combination lock.

The structure of the utility model suitcase combination lock please cooperate consults shown in Figure 1ly, and it mainly is by slide block 2, Slave Block 3 and spring 4 and is cooperating entire combination such as box body 5, push button 6, structure 7 and digit wheel 8 to become complete lockset.Wherein:

Slide block 2 is provided with a chute 21, establishes a hypotenuse groove 22 again in the edge of chute 21, and then there is a short slot 23 at the back side of hypotenuse groove 22, and is provided with a hole 24 on slide block 2, and its bottom is provided with two protruding tongues 25.

Slave Block 3 is provided with a clamping stagnation key 31 and trace 32, and is provided with a boss post 33 in the ora terminalis of trace 32, and offers short slot 34 rearward, and a top 341 is arranged on it, with putting spring 4 starts.

Box body 5 is offered an interface 51 and push button perforation 52 on its positive box face.

Push button 6 is to think to provide to pass slide block and Slave Block sporter.

Structure 7 is a body that can cooperatively interact with box body 5, and its structure 7 is provided with two guide rods 71, and offers a caulking groove 72 between two guide rods 71, and a top 73 is arranged below this caulking groove.

Digit wheel 8, it is that the wheel plate-like is provided with a C type ring 81.

Below, cooperate Fig. 2,3 to illustrate again.Slave Block 3 is assembled on the structure 7, and then with chute 21 cover of slide block 2 with on the guide rod of structure 7 on 71; At this moment, boss post 33 on the trace 32 can place the short slot 23 of slide block 2 just, boss post 33 then formation is the state of contacting with hypotenuse groove 22, then, form the butt state between the top 73 that provides a spring 4 to be placed in Slave Block 3 short slots, 34 tops 341 and structure 7 caulking grooves 72 again, thereby make boss post 33 keep contacting with the apical margin of hypotenuse groove 22; Digit wheel 8 then is to be installed in side under the slide block 2, and the outer rim of its C type ring 81 contacts with protruding tongue 25; Afterwards, then box body 5 is installed on the structure 7, be fixed in the hole 21 of slide block 2 after again push button 6 being passed its push button perforation 52, and interface 51 is positioned at clamping stagnation key 31 positions of Slave Block 3 just, has finished assembling like this and has cooperated.

So, when digit wheel 8 rotates to when making its C type ring 81 breach just place the position of protruding tongue 25, then slide block 2 just can by push button 6 towards the traction power of right and its protruding tongue 25 is entered in C type ring 81 breach of digit wheel 8, making hypotenuse groove 22 that pressure zone boss post 33 jointly moves downward vertically, cause whole Slave Block 3 also to moving down, clamping stagnation key 31 on the Slave Block 3 is snapping fastener thereupon the clasp that leaves fastener and no longer then, so that open suitcase (shown in Fig. 3 imaginary line); Afterwards, when loosening push button 6, then can utilize the active force of spring 4 and slide block 2, Slave Block 3 are returned back to original position once again, then clamping stagnation key 31 fastener (shown in the solid line of Fig. 3) that also links closely once again; And then after rotation digit wheel 8 made the displacement of its C type ring 81 breach, then protruding tongue 25 was positioned at the outer rim of C type ring 81 and is being blocked, and slide block 2 can't be promoted, so clamping stagnation key 31 keeps linking closely fastener.

When in sum, the utility model can be simplified suitcase combination lock inner body and strengthen its structural strength, minimizing mounter.
