At first, see also Fig. 1,2,3, the utility model embodiment is made of assemblies such as a main body 10, a lower cover 20, an operating key 30, a core 40, two action bodies 50 and two springs 60, wherein:

Main body 10, central authorities have an oval slotted eye 11, front end then has two alcoves 17, inside has some wall 121,123,124, mast 13,14, two protruding axle 15 and two nose bars 16 of supporting respectively, these support wall is to be positioned at around the slotted eye 11, and protruding axle 15 and nose bar 16 then are positioned at the front end both sides of slotted eye 11.

Lower cover 20, be to be riveted on the mast 13 with rivet 21, make it to be positioned at main body 10 bottoms, front end has two flexure strips 22 that slightly are Jiong shape, be to place in this two alcove 17, have a slightly L-shaped slideway 23 on it, these slideway 23 both sides respectively have the protruding bamboo shoot 24 of an elasticity, and slideway 23 upper ends have barricade 25.

Operating key 30 is to place in the oval slotted eye 11 of this main body, by these support wall 121,122,123,124 encloses to, its both sides, bottom respectively have a driving lever 31.

Core 40 is to install from lower to upper to be placed in the operating key 30, and its bottom surface has a block 41, is placed in the L shaped slideway 23 of lower cover, and a fixture block 42 respectively is equipped with at two ends, and fixture block 42 bottom surfaces have a draw-in groove 421.

Action body 50 has axis hole 51 being sheathed on the protruding axle of main body 15, and forms the bilateral symmetry state, and front end has a grab 52, and the both sides, rear end respectively have one and support a bar 53 and a push rod 54, and should support bar 53 be that perseverance is positioned at operating key driving lever 31 rears.

Spring 60 is to be sheathed on main body nose bar 16 and to move body between the bar 53.

According to behind the above-mentioned unit construction, the utility model is to be blocking under normal conditions, shown in Fig. 3,5, the mast 14 of the borrower of elder generation body is bolted in the leather trunk upper end with lockset integral body, wherein, operating key 30 rear ends are and main body has suitable spacing to 121 on wall, and front end peaks to wall 124.Core block 41 is the lengthwise position places that are positioned at the L shaped slideway 23 of lower cover, and 42 of two ends draw-in grooves are vertical state and do not engage with the protruding bamboo shoot 24 of lower cover.The grab 52 of action body 50 is to be stuck in the main body alcove 17, and hooks the slider of zipper fastener A of leather trunk slide fastener, and supporting bar 53 is to be positioned at operating key driving lever 31 rear ends, and 54 of push rods are positioned at both sides, operating key 30 bottom.And spring 60 is to be contraction state.This moment, the leather trunk slide fastener was to be closure state, and slider of zipper fastener A presses down the flexure strip 22 of lower cover.

As desire to open leather trunk, then be to promote operating key 30 (shown in Fig. 3 direction of arrow) backward with the finger application of force, support bar 53 to borrow driving lever 31 pushing tows, making action body 50 is that fulcrum rotates an angle with protruding axle 15, deviate from alcove 17 and chain link head A, state as shown in Figure 4 so as to synchronous drive grab 52.This moment, slider of zipper fastener A borrowed the elastic force of flexure strip 22 to upspring immediately, to unzip and then to open leather trunk, then as long as the pine oil finger, operating key 30 will be at once borrowed the pulling force of spring 60 and the return that moves forward automatically, the body 50 that moves is simultaneously also borrowed these spring 60 pulling force and revolution playback automatically, grab 52 is snapped in the alcove 17 once again, promptly recover original blocking as shown in Figure 3.Yet because of slide fastener is opened, so grab 52 does not block slider of zipper fastener A, need only and slide fastener is pulled on again this moment, and slider of zipper fastener A is inserted in the alcove 17, can be blocked the blocking that recovers fully as shown in Figure 3 by grab 52 once again.

What need stress is, the utility model is equiped with core 40 in operating key 30, be provided with a clip mechanism between its bottom and the lower cover 20, comprise the L shaped slideway 23 that is positioned at lower cover 20, the protruding bamboo shoot 24 of elasticity, barricade 25 are with the block 41 that is positioned at core 40 bottoms, fixture block 42 and be positioned at the push rod 54 etc. of action body 50 rear ends.Therefore, when the leather trunk locking, can borrow key to insert core 40, make its block 41 slide to lateral position, and blocked by barricade 25 along the L shaped slideway 23 of lower cover 20 also with about 90 degree of it rotation.Simultaneously its both sides fixture block 42 also borrows draw-in groove 421 to engage with the protruding bamboo shoot 24 of the elasticity of lower cover 20, and fixture block 42 more props up push rod 54, please consults simultaneously shown in Fig. 5,6, operating key 30 and driving lever 31 thereof can't be moved, to reach the purpose of the second road locking behind the pushing tow.Certainly, when opening leather trunk again as desire, then must be earlier again with key revolution core 40, make its block 41 returns no longer by barricade 25 bumping posts, fixture block 42 also breaks away from the protruding bamboo shoot 24 of elasticity simultaneously, and no longer props up push rod 54, promptly shown in Fig. 3,7, can move operating key 30 after the application of force this moment, breaks away from slider of zipper fastener A to make grab 52, and finish the action of opening leather trunk.

By above explanation as can be known, the utility model has possessed following all advantage and effect at least, and more progressive practical more than located by prior art:

1. simple structure only is made up of minority elements such as main body, lower cover, operating key, core, action body and springs, and assembling is very easy and rapid especially, for manufacturer, can reduce cost significantly.

2. utilize key to open and close, not only convenient in operation, and the worry of anopsia or sight line.

In sum, the disclosed concrete structure of the utility model, through look into really and located by prior art completely different, and possess novel initiative important document, and have more simple structure, assembling reaches effects such as easy to operate easily rapidly, and possesses progressive practical important document, meet relevant novel patent requirement fully, so propose patent application in accordance with the law.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
