The specific embodiment
Below in conjunction with a specific embodiment, the utility model is described in further detail.
Referring to accompanying drawing 1, to shown in accompanying drawing 5, the utility model comprises covering plate structure 1, sheet for bottle lid lock 2 and the key 3 for unblanking.Described covering plate structure 1 comprises sheet for bottle lid lock mount pad 101, for fixing the connection cramp 102 of other adjacent cover plates, the cover plate 103 being rectangle, and the lifting mouth 104 that is used for lifting by crane cover plate 103 at cover plate 103 two ends, at the vertical cover plate 103 that connects of sheet for bottle lid lock mount pad 101, there is circular keyhole 105 simultaneously.Lock with sheet for bottle lid the sheet for bottle lid lock 2 that mount pad 101 matches and is positioned at cover plate 103 bottoms, comprise dead bolt 201 and lock housing 202.Wherein, dead bolt 201 is provided with through hole 201-1 in the one end near lock housing 202 along dead bolt 201 thickness directions, dead bolt 201 can rotate about through hole 201-1, this through hole 201-1 is inner with two lock tooth 201-2, two lock tooth 201-2 become symmetric relation, two lock tooth 201-2 are upper with toward each other and be the curved surface 201-3 of arc surface, and two curved surface 201-3 to surround formed circular diameter larger than keyhole 105 circular diameters on cover plate 103.Sheet for bottle lid latch mechanism also comprises the key 3 for unblanking, described key 3 comprises the key shell 301 that is positioned at key 3 left and right sides and becomes plane symmetry, key shell 301 is positioned at position, its underpart shelly structure, this shelly structure has a movable block through hole 304, movable block 302 has matched with movable block through hole 304, these movable block 302 inside center positions are provided with blind hole 305, movable block 302 structurally comprises that side is piece 302-1 and the rectangular blocks 302-2 of curved surface, the length of this rectangular blocks 302-2 and width are greater than the correspondingly-sized of movable block through hole 304, after key 3 assemblings, the piece 302-1 of the curved surface of movable block 302 will intert movable block through hole 304, and can free in and out activity, rectangular blocks 302-2 is close to the inner side of movable block through hole 304.Two of left and right movable block 302, after the whole assembling of key 3, accompanies a spring 303 in the middle of two movable blocks 302, and the two ends of spring 303 are enclosed within respectively in the blind hole 305 of movable block 302.In use, the movable block 302 that is positioned at key 3 left and right sides can be by inwardly movable and reset thereupon of Compress Spring 303 for key 3.
Sheet for bottle lid latch mechanism in use, other cover plates that Yu Ben mechanism cover plate 103 matches first hook are contained on cable trench mounting base, when last cover plate 103 of the present utility model is installed, be arranged on cover plate 103 bottoms and stretch out the connection cramp 102 of little section of cover plate 103 1, will under the effect cooperatively interacting at lower bayonet slot 107, clamp adjacent cover plate.Sheet for bottle lid now lock 2 will be fixed on and connect on the sheet for bottle lid lock mount pad 101 of cramp 102 contrary sides, and sheet for bottle lid is locked dead bolt 201 in 2 and is also adjacent to key shell 301, the state in unblanking away from one end of through hole 201-1.The upper draw-in groove 106 of cover plate 103 one end contrary with connecting cramp 102 is snapped on the lower bayonet slot of adjacent cover plate, use key 3 through the keyhole 105 on cover plate 103, because key 3 is under the state opening, the horizontal maximum length that is positioned at the movable block 302 of key 3 left and right sides is greater than the diameter of keyhole 105, the movable block 302 of key 3 is when passing through keyhole 105, will be subject to the extruding of keyhole 105 inwalls, the spring 303 that is set on the interior blind hole 305 of portable plate 302 also can be subject to the inside extruding contraction of portable plate 302, such two portable plates 302 will be simultaneously inwardly movable.Portable plate 302 is after passing keyhole 105, and two portable plates 302 will can not be squeezed and resilience.Two lock tooth 201-2 that on dead bolt 201, through hole 201-1 adheres to are because mutually corresponding and symmetrical, along through hole 201-1 inwall, circumferentially there is certain sinking space in both, portable plate 302 on key 3 by resilience in sinking space, rotating 3 of keys will make portable plate 302 block two lock tooth 201-2, thereby also drive dead bolt 201 half-twists to snap into the cover plate bottom position that Yu Ben mechanism place cover plate 103 closes on, such two adjacent cover plates are by locking and fix.Locked after cover plate 103, key 3 is from again extracting out along keyhole 105, and key 3, in extraction, can again be subject to the extruding of keyhole 105 and shrinks, thereby by cover plate 103, is extracted out smoothly, realizes the action of the adjacent cover plate of sheet for bottle lid lock 2 locking.
The dead bolt 201 of the present utility model circular diameter that the curved surface 201-3 of tooth 201-2 forms of locking is larger than keyhole 105, the particular location that does not inwardly observe lock tooth 201-2 from the keyhole 105 of cover plate 103, such structure possesses superior effect for the theftproof performance of cover plate 103.The compact conformation of sheet for bottle lid latch mechanism, rationally distributed simultaneously, can adapt to comparatively severe working environment, is worth being promoted.
The examples of implementation of the above are only the preferred embodiment of the utility model, not with this, limit practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
