In addition, the upper position and the lower position between the surface of the lock body and the platform surface are respectively provided with an arc-shaped surface, both sides of which are respectively provided with a through hole, one end of which is upward extended with a dentate lug. The lock body is provided with a groove snapping a lock core. The inner side of the lock body is provided with two lock sheet guide grooves snapping the lock core lock sheet. The utility model has the advantages that the structure is simple, the mounting efficiency is good, the failure is not easy to generate, the material cost is low, the use is convenient, the disassembly can be made without a special tool, etc.

Description

But the lock body of quick-snap

The utility model relates to a kind of lock that is used for desk, is meant the lock body of forming lock especially.

As shown in Figure 1, it is the stereogram of general lock body, wherein this lock body A goes up with iron nail (figure does not show) and hammers into plate body B and fixing lock body A, but, when hammering into lock body A, often also excessive or angular deflection because of the application of force, cause hammer to strike middle plate body B, cause this plate body B surface depression, form apparent major imperfections, and this lock body A and plate body B be when assembling, also because of narrow (be in the plate body B with the limited narrow space of table limit C) on the space, and the more feasible assembling degree of difficulty that increases lock body A makes operation slowly be difficult for assembling.

Now sum up the existing shortcoming of existing lock body as follows:

1. part is numerous and diverse.

2. installation effectiveness is poor.

3. easily break down.

4. material cost height.

5. use inconvenience.

Therefore, but the purpose of this utility model be to provide a kind of simple structure, assembling easily, the lock body of the quick-snap that is difficult for breaking down, make easy to use and cost low.

But the purpose of this utility model is achieved in that a kind of lock body of quick-snap, it is the column of a hollow, it is characterized in that: the surperficial both sides of this lock body are respectively equipped with a flat upper surface, are provided with an open-work in flat upper surface central authorities, and this open-work one end extends upward an oblique projection; Be provided with an arcwall face respectively at the surface and two places up and down alternate of lock body in addition, be respectively equipped with an open-work again in the both sides of arcwall face, and this open-work one end extend upward a dentation projection with flat upper surface; Be provided with the groove that sill close core in this lock body; This lock body inboard is provided with the locking plate guide groove that two sill close the core locking plate.

Hence one can see that, the utility model is owing to be provided with oblique projection and dentation projection in surface of lock body, so when the installing lock body, can utilize the elastic force of this oblique projection and dentation projection that lock body is fastened in the plate body, and be to utilize this oblique projection and dentation projection that lock body can be fixed in the open-work in plate body more securely, easy and simple to handle, combination is fast.

Therefore, the utility model has produced following beneficial functional by above technical scheme:

1. simple structure.

2. installation effectiveness is good.

3. be difficult for breaking down.

4. the cost of material is low.

5. easy to use.

6. must the special tool(s) dismounting.

7. have an industrial utilization.

Further specify the utility model below in conjunction with drawings and Examples.

Fig. 1 is the three-dimensional combination figure of existing lock body.

Fig. 2 is a three-dimensional combination figure of the present utility model.

Fig. 3 is an exploded view of the present utility model.

Fig. 4 is a schematic diagram before the action of the present utility model.

Fig. 5 is an action of the present utility model back schematic diagram.

The utility model as shown in Figure 3, this lock body 1 is a hollow column, be respectively equipped with a flat upper surface 13 in the both sides of its external surface, these flat upper surface 13 central authorities are provided with an open-work 17, and these open-work 17 1 ends extend upward an oblique projection 2, be provided with an arcwall face 16 respectively at the external surface of this lock body 1 and two places alternate again with flat upper surface 13, and be respectively equipped with an open-work 18 in the both sides of arcwall face 16, and these open-work 18 1 ends extend upward a dentation projection 21, in installing during lock body 1, lock body 1 is fixed in plate body 4 by the elastic force of this oblique projection 2 and dentation projection 21; Be provided with two locking plate guide groove 11,14 and grooves 15 in this lock body 1, in order to installing core 5;

Again as shown in Figure 3, be provided with round 51,512 in the both sides of core 5, locking plate 52,53 and spring 54,55 are arranged in wherein, these locking plate 52,53 1 sides are provided with a fin 56,57, with contained spring 54,55 compressions, form a compression elasticity by this fin 56,57, the feasible different key sawtooth sign indicating numbers of can arranging in pairs or groups, because of the collocation of this locking plate 52,53 and key sawtooth sign indicating number, because of non-feature of the present utility model, so will not describe in detail.When this core 5 is installed in the lock body 1, by the groove 15 in this lock body 1 core 5 sill are combined in the lock body 1, pass through of locking plate 52,53 ejections of the compression elasticity of spring 54,55 again, and sill are combined in the locking plate guide groove 11,14, form the kayser state with core 5.

As shown in Figure 2, be one by lock body 1, core 5, the lock 6 that swing handle 3 and nut 33 combine, when installing lock 6 (seeing also Fig. 4 and shown in Figure 5), because set oblique projection 2 of array and dentation projection 21 on lock body 1 external surface, in the window shape open-work 41 that lock 6 is fixed in plate body 4 by the elastic force of this oblique projection 2 and dentation projection 21, make the lock body 1 can be more firmly in plate body 4, again because of being provided with a square column 58 in these core 5 one sides, these square column 58 central authorities are provided with a bolt 59, by square hole 31 fits of this square column 58 with swing handle 3 central authorities, and utilize nut 33 that swing handle 3 spiral shells are solid on core 5, when inserting lockhole 510 with key, with locking plate 52,53 inwardly draw, and make core 5 rotations, rotate swing handle 3 simultaneously and are fastened in the croze 511, reach the purpose of locking, otherwise then unblank, with this simple mechanism, easy operation, and then make the effect of effective start.Reach the purpose that prevents that the thief from stealing.
