Abstract
The utility model relates to a theft proof electromagnetic lock for a powder supply transformer. The utility model is composed of a transformer casing box body, an electromagnetic lock, an intermediate frequency power supply, and a 15V15A power supply. The utility model is characterized in that the electricity and the mechanically are organically integrated, a lock body can be completely hidden in the transformer casing, and the lock trace can not be seen form appearance; thereby, a cover of a transformer can not be opened for taking a core when the power network is powered off, when the transformer is powered on, the transformer casing cover has the high voltage, and people can not approach the transformer, and the burglary accident of the transformer can be efficiently prevented. The utility model has the advantages of simple structure, low cost, and convenient operation; The utility model can has the function of preventing the transformer form stealing and is an ideal theft proof electromagnetic lock for a powder supply transformer.
Description
The utility model relates to a kind of electromagnetic lock, particularly a kind of electric power transformer anti-theft electromagnetic lock.
The present theftproof lock of power transformer, employing be that single frame for movement is antitheft because its structural leaking outside property can not play real antitheft effect.
The purpose of this utility model provides a kind of electric power transformer anti-theft electromagnetic lock, and this antitheft electromagnetic lock combines with frame for movement electric, lock body is fully hidden in casing, make appearance can't see the vestige of lock, make transformer when electrical network does not have electricity, can't beat lid and get core, and when electricity is arranged, transformer tank covers and high-tension electricity is arranged, personnel can't be approaching, and in addition, required supply frequency of electromagnetic lock and voltage and transformer frequency response are not inconsistent, do not have ad hoc power supply, can't unblank yet; Thereby prevent the robbery accident of transformer effectively, in order to overcome existing deficiency with the transformer anti-theft lock.
The purpose of this utility model can reach by following embodiment:
The utility model is made up of transformer case casing, electromagnetic lock, intermediate frequency power supply and 15V15A power supply, the transformer case casing is existing part, intermediate frequency contactor, electromagnet, reversing bar, pull bar and tapered end are arranged on the electromagnetic lock, intermediate frequency contactor is an auxiliary reclay, its energising makes the constant open contact closure in the solenoid circuit, electromagnet drives reversing bar, and reversing bar drives pull bar, and pull bar drive tapered end is finished and unclamped and locking work.Electromagnet is connected with reversing bar by guide rod, reversing bar is connected with pull bar by three holes on it and pin, pull bar is connected with tapered end by connector, pull bar, connector and tapered end all have two, spring is arranged in the tapered end, tapered end realizes that by the spring reciprocating action under the effect of electromagnet in it dead bolt pins the transformer case lid.
Appliance circuit of the present utility model is made of intermediate frequency power supply, 15V15A power supply, contactor PJ and electromagnet DCT, above-mentioned member is commercially available, its annexation is that intermediate frequency power supply ZPF meets contactor PJ from beginning to end, the constant open contact of contactor PJ is connected in the electromagnet DCT circuit, 15V15A power supply KB meets electromagnet DCT, so the unlatching of electromagnetic lock is finished by intermediate frequency power supply and the acting in conjunction of 15V15A power supply, the two lacks one can't open, and this has just played antitheft effect effectively.
The utility model advantage is simple in structure, select valency cheap, use easy to maintenance, combine with frame for movement electric, lock body is fully hidden in casing, make appearance can't see the vestige of lock, have only just can unblank to beat to cover and get core with two kinds of predetermined power source, thereby having prevented the robbery accident of transformer effectively, is a kind of antitheft electromagnetic lock of desirable power transformer.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is mechanical part overall structure figure of the present utility model
Fig. 2 is its upward view
Fig. 3 is electric elementary diagram
As Figure 1-3, this lock is by transformer case casing 7, electromagnetic lock, intermediate frequency power supply 5 and 15V15A power supply 6 are formed, transformer case casing 7 is existing part, intermediate frequency contactor 12 is arranged on the electromagnetic lock, electromagnet 1, reversing bar 2, pull bar 3 and tapered end 4, constant open contact 8 in intermediate frequency contactor 12 closing electromagnets 1 circuit, electromagnet 1 is connected with reversing bar 2 by guide rod 9, reversing bar 2 is connected with pull bar 3 by three holes on it and pin, pull bar 3 is connected with tapered end 4 by connector 10, pull bar 3, connector 10 and tapered end 4 all have two, spring 11 is arranged in the tapered end 4, tapered end realizes that by spring 11 reciprocating action under the effect of electromagnet 1 in it dead bolt pins the transformer case lid.
