Detailed description of the invention
As shown in Fig. 1 ~ Fig. 7, the locking device for casing of the present embodiment comprises locking closure 2 and lock core 3, locking closure 2 one end is articulated with on the first casing 11, the other end is hinged by bearing pin 4 and lock core 3, lock core 3 is located at the inner side of locking closure 2, be provided with spring 5 between lock core 3 and locking closure 2, the second casing 12 is provided with latch part 121, and lock core 3 is provided with the tapered end 31 for matching with latch part 121.
In the present embodiment, the first casing 11 is case lid, and the second casing 12 is chest body, in addition also can as required, and using the first casing 11 as chest body, the second casing 12 is as case lid, and operation principle of the present invention is also identical.
As shown in Fig. 8, Fig. 9 and Figure 10, in the present embodiment, tapered end 31 is provided with level and smooth lock core approaching face 311 by the side of latch part 121.Lock core 3 is provided with deflection limiting section 32, and spring 5 and deflection limiting section 32 are located at the both sides of bearing pin 4 respectively.When tapered end 31 matches with latch part 121, the locking face 312 of tapered end 31 can prevent tapered end 31 from exiting from latch part 121.
As shown in Figure 11, Figure 12 and Figure 13, in the present embodiment, locking closure 2 is provided with the sealed groove 21 of casing, the sealed groove 21 of casing comprises locking face 211 and lower locking face 212, side by locking closure 2 on first casing 11 is provided with first case of protrusion along 111, upper locking face 211 matches with the first casing 11 when casing is sealed, and the side by latch part 121 on the second casing 12 is provided with second case of protrusion along 122, and lower locking face 212 matches along 122 with second case when casing is sealed.In the present embodiment, latch part 121 is provided with level and smooth casing approaching face 123 by the side of tapered end 31.Locking closure 2 one end is provided with the first axis hole 201, the other end be provided with the second axis hole 202, first axis hole 201 by latch and the first casing 11 hinged, bearing pin 4 is located at the second axis hole 202.
In the present embodiment, locking closure 2 is provided with the first spring eye 51, and lock core 3 is provided with the second spring eye 52 be oppositely arranged with the first spring eye 51, and spring 5 one end vertically contacts in the first spring eye 51, and the other end vertically contacts in the second spring eye 52.
The course of work of the present invention is as follows: when needing fastened housing, first locking closure 2 is dug, after first casing 11 and the second casing 12 are closed, locking closure 2 is put down and applies pressure, so the tapered end 31 of locking closure 2 with movable lock core 3, lock core 3 enters latch part 121 and locks under the guide effect of lock core approaching face 311, casing approaching face 312, spring 5 produces thrust to lock core 3 simultaneously, prevents tapered end 31 from coming off in latch part 121.Then locking closure is compressed, make the sealed groove 21 of casing by first case along 111, grip along 122 for second case, thus realize the locking to casing, the deflection limiting section 32 of lock core 3 props up the inner surface of locking closure 2 simultaneously, effectively prevents lock core 3 from crossing and turns.When needing to unlock casing, first the side of locking closure 2 near spring 5 is pinned, deviate from latch part 121 so spring 5 extrudes tapered end 31, drive locking closure 2 outwards to overturn simultaneously, thus remove on the one hand the sealed groove 21 of casing to first case along 111, grip along 122 for second case, also thoroughly relieve the locking between tapered end 31 and latch part 121 simultaneously, thus easily can open casing.
The foregoing is only the preferred embodiment of the present invention, protection scope of the present invention is not limited in above-mentioned embodiment, and every technical scheme belonging to the principle of the invention all belongs to protection scope of the present invention.For a person skilled in the art, some improvements and modifications of carrying out under the prerequisite not departing from principle of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
