One fixing fairlead is set in the described lock body chamber, and the dead bolt front end passes the hole in the middle of the fairlead earlier, stretches in the dead bolt outlet of lock body wall again.
The described lock body wall that has the dead bolt outlet is a gland, between fairlead and the gland oil sealing is set, and is mainly used in and prevents that foreign material from entering in the lock.
The antitheft ancient power lid of a kind of magnetic control, comprise the lock installed on lid and the lid and the key of configuration, it is characterized in that described lock body is installed in the submarginal position of lid inner face, described lock body is provided with the rivet-like dead bolt in the chamber, the dead bolt front end stretches in the outlet of lock body wall dead bolt, locking endoceliac spring one end withstands on the dead bolt rear end face, the other end withstands on the lock body inwall, on the dead bolt rear end face magnet is set, described key front end is provided with caulking groove, magnetic coding according to magnet on the dead bolt is arranged, and magnet corresponding one by one with dead bolt rear end face magnet positions and that magnetic polarity is opposite is set in the key caulking groove; On lid, key hole is set near the relative sidewall edge of lock body dead bolt outlet.
One fixing fairlead is set in the lock body chamber that the antitheft ancient power of described magnetic control covers, and the dead bolt front end passes the hole in the middle of the fairlead earlier, stretches in the dead bolt outlet of lock body wall again.
It is a gland that the antitheft ancient power of described magnetic control covers the lock body wall that has the dead bolt outlet, between fairlead and the gland oil sealing is set, and is mainly used in and prevents that foreign material from entering in the lock.
The utility model compared with prior art has the following advantages and good effect:
1, because of mainly adopting the principle of magnetic coding, magnetic control, the antitheft ancient power cover lock of the utility model magnetic control and key carry out the theft protection design of Gu Li lid and the antitheft ancient power cover lock of magnetic control, other people are difficult to dispose the key that has corresponding magnetic coding magnet with the antitheft ancient power cover lock of magnetic control, have strengthened antitheft safety and reliability greatly.
2, the antitheft ancient power lid of magnetic control of the present utility model is rational in infrastructure, has the advantages that cost is low, survivability is strong, and key hole is that through hole is difficult for stopping up, and survivability is strong, and the staff opens easy, quick with private key.
3, the technical solution of the utility model has taken into full account the factors such as activities of environment for use, working specification (custom) and the manufacturer of the ancient power lid of existing use, is convenient to the transformation to existing ancient power lid.The theft protection key that has paid particular attention to Gu Ligai (and various pipeline manhole lid) is not allow arbitrarily to open, solved the theft protection difficult problem of various ancient power lids (and various pipeline manhole lid), can avoid because ancient power lid is illegally opened the personal injury that causes and the loss of down-hole facility.
Description of drawings
Fig. 1 is the antitheft ancient power cover lock user mode sectional structure chart of the utility model magnetic control.
The specific embodiment
Referring to Fig. 1, the antitheft ancient power cover lock of a kind of magnetic control is installed a gland 2 on lock body 4 front openings, seal opening, and the dead bolt outlet is set on gland 2.In lock body 4 chambeies rivet-like dead bolt 1 is set, dead bolt 1 front end passes the hole in the middle of the copper fairlead fixing in lock body 4 chambeies 5 earlier, stretches in the dead bolt outlet on the gland 2 again.Between copper fairlead 5 and gland 2, oil sealing 3 is set.Spring 6 one ends in lock body 4 chambeies withstand on dead bolt 1 rear end face, and the other end withstands on lock body 4 cavity walls.Be provided with on dead bolt 1 rear end face and press the magnet 7 that the magnetic coding is arranged.Described key 9 front ends are provided with caulking groove, arrange according to the magnetic coding of magnet on the dead bolt 1, and magnet 8 corresponding one by one with dead bolt 1 rear end face magnet 7 positions and that magnetic polarity is opposite is set in key 9 caulking grooves.
The antitheft ancient power lid of a kind of magnetic control is fixed on Gu Li with above-mentioned lock body 4 by connector and covers the submarginal position of 10 inner faces, near lock body 4 glands 2 relative sidewall edges key hole 12 is set on Gu Li lid 10.
Wherein: dead bolt 1 adopts stainless steel material, is mainly used in to pin ancient power lid 10.Gland 2 adopts stainless steel or brass, is mainly used in and pushes down oil sealing 3.Oil sealing 3 adopts conventional oil sealing, is mainly used in and prevents that foreign material from entering in the lock.Lock body 4 adopts stainless steel material.Fairlead 5 adopts copper material, and main effect is that the motion of dead bolt 1 is led.Spring 6 adopts stainless steel material, and it is shaped as tower, and main effect is to push dead bolt 1 to lock position.
Magnet 7,8 on dead bolt 1 and the key 9 all adopts rareearth magnetic material, and the pole polarity of dead bolt 1 and key 9 opposing end surfaces must opposite (otherwise can not attract each other), and the magnetic pole number of poles of end face is 1 or 2,4 separately ... even numbers.Magnetic control key 9 plates adopt ordinary metallic material.
The operating principle of the antitheft ancient power cover lock of magnetic control:
When ancient power lid is normal when using, dead bolt 1 ejects the dead bolt outlet of gland 2 left under the effect of spring 6, and dead bolt 1 front end reaches under the cyclic convex edge with ancient power cage 11, and ancient power lid 10 is pinned.When needs are opened ancient power when covering 10, magnetic control key 9 is inserted downwards in the key hole 12 according to the direction of arrow, because of magnet 7 numbers of poles on the rear end face of on the key magnet 8 and dead bolt 1 fit like a glove and polarity opposite, when the magnet on the key 98 leans against on the relative outer wall of lock body 4 glands 2, and with the rear end face of dead bolt 1 on magnet 7 positions to timing, dead bolt 1 is to right-hand motion under the magneticaction that attracts each other, Gu Li lid 10 can be thrown off with ancient power cage 11, also have conventional open hole on the Gu Li lid 10, can open according to original mode.
Cover Gu Li lid 10, magnetic control key 9 is upwards extracted according to the direction of arrow, dead bolt 1 ejects the dead bolt outlet of gland 2 left under the effect of spring 6, and dead bolt 1 front end reaches again under the cyclic convex edge of ancient power cage 11, once more ancient power lid 10 is pinned.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
