The specific embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: like Fig. 1,2, shown in 5; It comprises the anti-skid plate 1 and the internal fixation plate 2 that are installed in the door-plate both sides, is arranged on the lock body 4 between internal fixation plate 2 and the external fixation plate 3, and said lock body 4 is provided with pressing plate 5, fixed head 6, dead bolt 7 and key holder 8; Said pressing plate 5 tops be provided with one have a groove 10 eccentric wheel 9; This eccentric wheel 9 be installed in door-plate in and the interior commentaries on classics part 11 that is wound with one group of clockwork spring 12 link to each other; Clockwork spring 12 can diminish powerful external force; Avoid the hard power damage of lockset, the said interior part 11 that changes links to each other with the outer commentaries on classics part 14 that is arranged on anti-skid plate 1 outside through axostylus axostyle 13; Be connected with a connecting rod 15 on the said dead bolt 7, this connecting rod 15 vertically passes fixed head 6 and pressing plate 5, and is rotationally connected with eccentric wheel 9; All offer the perforation of mutual correspondence on said fixed head 6, dead bolt 7 and the key holder 8, and in said perforation, be provided with baffle mechanism and billiard mechanism; Said key holder 8 bottoms offer one be used to place key key 16.
Said baffle mechanism comprise the W shape that is arranged in fixed head 6 perforation first baffle plate 17, be arranged on the square second baffle 18 in dead bolt 7 perforation and be arranged on the 3rd baffle plate 19 of the T shape in key holder 8 perforation; Said billiard mechanism has three groups of pellet shot from a slingshot groups, comprise the band spring that is arranged in fixed head 6 perforation the first pellet shot from a slingshot group 20, be arranged on the square second pellet shot from a slingshot group 21 in dead bolt 7 perforation and be arranged on the 3rd pellet shot from a slingshot group 22 of the band spring in key holder 8 perforation.
The recess of said first baffle plate 17 is provided with spring; Said the 3rd baffle plate 19 both sides are provided with spring.
Leave space 23 between said pressing plate 5 and the fixed head 6; And between said pressing plate 5 and fixed head 6, be provided with the set screw 24 of band spring; Said dead bolt 7 afterbodys are provided with back-moving spring 25.
Be provided with a key track 26 between said anti-skid plate 1 and the internal fixation plate 2, and this orbit plane and key 16 are on the same horizon.
Open the key of said theftproof lock, comprise the shank of the key 27 and key piece 28, offer on the said key piece 28 with the 3rd baffle plate 19 corresponding through holes 29 and with the arrange Baltimore groove 30 of the different depth that matches of the 3rd pellet shot from a slingshot group 22; Said the shank of the key 27 is connected the side of key piece 28.
Like Fig. 1, shown in 2; Rectangle keyhole 31 on the anti-skid plate 1 is corresponding with key piece 28 bases, and key is pushed anti-skid plate 1, advances and prop up internal fixation plate 2 along key track 26; Screw key 90 is spent then; Make key piece 28 aim at key 16, once more key is pushed, this moment, whole key got in the theftproof lock fully; Rotate the outer part 14 that changes, drive eccentric wheel 9 rotations by axostylus axostyle 13, eccentric wheel 9 presses down; Make pressing plate 5 descend, first baffle plate 17 and the first pellet shot from a slingshot group 20 are stressed to lower slider, and promote the corresponding second baffle 18 and the second pellet shot from a slingshot group 21 respectively; The said second baffle 18 and the second pellet shot from a slingshot group 21 get in the dead bolt perforation fully; The 3rd baffle plate 19 falls in the through hole 29 on the key piece 28, and the 3rd pellet shot from a slingshot group slides to for 22 times in the Baltimore groove 30, because the degree of depth of said Baltimore groove 30 is different; And match with the length of said the 3rd pellet shot from a slingshot group 22, therefore the 3rd pellet shot from a slingshot group 22 is pinned with Baltimore groove is corresponding one by one; Simultaneously, eccentric wheel 9 promotes connecting rods 15 and drives the whole inwardly contraction of being made up of dead bolt 7, second baffle 18 and the second pellet shot from a slingshot group 21 to slide into and immerse in the lock body 4 unlocking condition promptly as shown in Figure 3 fully; At this moment, treat the door open after, dead bolt 7 is owing to lock body 4 is ejected in the effect of back-moving spring 25.
Directly rotate outward when changeing part when inserting not that key or key and theftproof lock do not match, cause above-mentioned unlocking action, eccentric wheel 9 promotion pressing plates 5; Baffle mechanism and billiard mechanism are continuously to lower slider; Make win baffle plate 17 and the first pellet shot from a slingshot group, 20 parts entering dead bolt 7, second baffle 18 and the second pellet shot from a slingshot group, 21 parts get into key holder 8, the three baffle plates 19 and 3 the 3rd pellets shot from a slingshot get into key 16 for 22 groups; Theftproof lock can't be opened, and is promptly as shown in Figure 4.
Because the shank of the key 27 and key piece 29 be at same straight line, and have the 3rd baffle plate 19 retainings in the 3rd pellet shot from a slingshot group 22 front portions, therefore double shield is provided for whole theftproof lock, the robber can't open with unlocking tool.
Except that the foregoing description, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
