The utility model is composed of a well ring, a well cover, a handle magnet, a handle, an inner rotation member magnet, an inner rotation member, a pin shaft, nuts, screw bolts, a pressure plate, a lock bolt, a fixed block, etc., wherein, the well ring is fixed on a well wall. A lock hole is arranged on the well ring, and the fixed block is fixed on the well ring. A lock cover hole is arranged on the well cover, and the screw bolts, the pressing plate and the inner rotation member are installed on the well cover. The inner rotation member magnet and the pin shaft are installed on the inner rotation member, and the nuts and the lock bolt are installed on the pin shaft. The handle magnet is installed on the handle.
Description
The utility model relates to a kind of well lid, especially a kind of magnetic transmission anti-stealing manhole cover with anti-theft device.
In daily life, the well lid on the road is usually stolen.This brings many inconvenience for people's live and work.
At present, though known various well lid part is equipped with anti-theft device, these anti-theft devices mostly be the latch-up-free structure or anti-theft locking device simple in structure, easily copied, destroyed.In known well lid use department, relate to municipal administration, electric power, water supply, numerous departments, these departments such as water, communication, military affairs, heating installation, coal gas, railway specifically need the function difference admittedly down, so the size of well lid, shape, all different with material.And existing anti-theft device can't manufacture the different needs that unified style satisfies above-mentioned numerous departments, if do not manufacture the anti-theft device of unified style, cost of production is very high again, has limited the development of producing.
The purpose of this utility model provides a kind of magnetic transmission anti-stealing manhole cover, it can manufacture anti-theft device the very low standard component style of cost of production, only change a lower magnet magnetic circuit, number of magnets, magnet arrangements order, just can satisfy the different needs of above-mentioned numerous department to well cover antitheft device, and be not subjected to well lid size, shape, with the restriction of material, be difficult for destroyed and imitated.
The purpose of this utility model is achieved in that the walling crib that has the lockhole that passes for dead bolt is fixed on the borehole wall, and magnetic transmission anti-stealing manhole cover card is placed on the walling crib of fixed block.On the magnetic transmission anti-stealing manhole cover handle patchhole is arranged, pressing plate, interior commentaries on classics part are installed.The interior commentaries on classics on part and the handle is equipped with the opposite permanent-magnet material magnet of magnetic polarity respectively.Handle inserts in the magnetic transmission anti-stealing manhole cover handle patchhole and rotates, being installed on handle and the interior commentaries on classics part two opposite magnets of the magnetic polarity coupled synchronization that attracts each other rotates, the interior rotation of changeing part makes the dead bolt that is installed on the bearing pin outwards move to extend out to and inserts the walling crib lockhole.Extract handle, magnetic transmission anti-stealing manhole cover is locked.During unlatching, the counter-rotation handle changes the part counter-rotation in magnetic coupling makes, and is installed in dead bolt on the bearing pin and inwardly moves to and leave the walling crib lockhole.Behind unlatching or the locking magnetic transmission anti-stealing manhole cover, handle is removed at ordinary times.The length of dead bolt depends on the size of magnetic transmission anti-stealing manhole cover and the diameter of interior commentaries on classics part.Change magnet magnetic circuit, number of magnets, the magnet arrangements order of installing on handle and the interior commentaries on classics part and just can satisfy numerous departments to the different needs of magnetic transmission anti-stealing manhole cover anti-theft device with prevent the purpose of copying.
Owing to adopt such scheme, when solution magnetic transmission anti-stealing manhole cover is antitheft, also can satisfy numerous different departments needs.
Accompanying drawing is a vertical section of the present utility model organigram.
Among the figure: 1. change in walling crib 2. magnetic transmission anti-stealing manhole covers 3. handle magnets 4. handles 5. and change part 7. bearing pins 8. nuts 9. bolts 10. pressing plates 11. dead bolts 12. fixed blocks in the part magnet 6.
In the drawings, walling crib (1) is fixedly on the borehole wall.Delineation piece (12) is fixed on the walling crib (2), and it can prevent that magnetic transmission anti-stealing manhole cover (2) from rotating, and is beneficial to the lockhole on dead bolt (11) the insertion walling crib (1).Pressing plate (10) is connected with magnetic transmission anti-stealing manhole cover (2) with bolt (9).The interior part (6) that changes can rotate on the boss of magnetic transmission anti-stealing manhole cover (2).In being installed in, changes on the part (6) bearing pin (7).There is circle hole sleeve to be contained on the bearing pin (7) on the dead bolt (11).Nut (8) is installed on the bearing pin (7).Be installed on the handle (4) handle magnet (3) be installed in to change magnetic circuit, magnet arrangements order, position, the number of magnets of the interior commentaries on classics part magnet (5) on the part (6) consistent, but magnet permanent-magnet material magnetic polarity is opposite, but the coupled synchronization rotation.
The said structure form is applicable to round well lid.As be used on the square well lid, fixed block (12) can omit.
Magnetic transmission anti-stealing manhole cover can select for use various materials to make.
