Abstract

The utility model provides a mistakenly-locking resistant lock device and belongs to mechanical locks. The mistakenly-locking resistant lock device comprises a lock body and further comprises an outer shell used for covering a lock head and a hinge shaft connected to the upper end face of the outer shell. The hinge shaft is connected with a turning cover used for sealing the end face of the outer shell. A hole is formed in the lower portion of the turning cover. A connecting board is arranged on the lower portion of the outer shell. A through hole corresponding to the hole in position is formed in the connecting board. The lock body penetrates through the hole and the through hole and locks the turning cover and the outer shell together in a closed mode. The mistakenly-locking resistant lock device is simple in structure, convenient to operate and capable of effectively preventing water from entering the lock head and preventing the lock head from being stolen and being used in an unauthorized mode.

Description

A kind of anti-misoperation locking device

Technical field

The utility model relates to a kind of blocking device, especially for the blocking device of switchboard or ring main unit.

Background technology

Now a lot of switchboards are all exposedly often will experience and expose to wind and rain out of doors, so the lock core ratio is easier to damage, and lock of light can't stop the protection to cabinet, still often there will be thievery.

On market, all structure is very complicated for a lot of blocking devices, and assembly difficulty is large, expensive, need to regularly be checked, and just in case bad, be difficult to spot repair, can incur loss through delay site work efficiency.

The utility model content

The purpose of this utility model, be to solve the problems of the technologies described above, and provides a kind of tapered end to switchboard to carry out airtight protection, both antitheft, stops again other people to open without authorization transformation cabinet, and simple in structure, easy to use.

Technical solution of the present utility model is: a kind of anti-misoperation locking device, comprise lock body, also comprise for covering the shell of tapered end, be connected to the jointed shaft of shell upper surface, described jointed shaft connects renovating for the closure end face, renovate bottom and offer hole, described outer casing underpart arranges junction plate, offers the through hole with the hole opposite position on described junction plate; Described lock body, through hole and through hole, will be renovated with enclosure closed and lock together.

By the shell of end face opening is set outside tapered end, turnover the renovating that is articulated and connected in end, this is renovated can be airtight by shell, then renovating with shell after airtight pinned by lock body.Stopped like this tapered end and extraneous contacting, both prevented that other people from using without authorization, simple in structure again, cost is low.

As preferably, described jointed shaft is connected to the medium position of shell upper surface, described renovate be inverted L shaped.Also some is opening in the upper surface of shell, after can renovating like this and opening, increases the inlet-duct area of shell, is conducive to operating personnel's operation.If shell is the opening of one side just, that operating personnel's ratio is easier to leave over hand.

As preferably, described shell is fixedly connected with by screw with the cabinet door of transformation cabinet.This is the simplest fixed form, is fixed up direct, convenient.

As preferably, described shell is connected with the tapered end of transformation cabinet.Prevent that like this some thief from directly dismantling the cabinet door and being stolen.

As preferably, described shell comprises the rear plate contacted with the cabinet door, on rear plate, offer for the through-core hole through tapered end, be fixedly connected with block on rear plate, connect the contiguous block arranged perpendicular to tapered end on block, connect the slide block that width is greater than the contiguous block width on contiguous block, offer groove and chute on described tapered end, described contiguous block moves in groove, and described slide block moves in chute.The width of described groove is less than the width of chute.

As preferably, offer a dismounting mouth that can break away from chute for slide block on groove.Rotate so whole shell, wait slide block to arrive dismounting mouthful correspondence position, just can extract blocking device.

As preferably, described renovating arranges weather strip, renovate with enclosure closed after, described weather strip can fit tightly the inwall of outer cover port.For strengthen renovating and shell between seal, can accomplish waterproof like this.

The utility model beneficial effect is: this apparatus structure is simple, easy to operate, can effectively to tapered end, carry out waterproof, antitheft, the anti-protection of using without authorization.

The specific embodiment

Below in conjunction with accompanying drawing, with embodiment, the utility model is described in further detail.

Embodiment 1, and as shown in Figure 1-2, a kind of anti-misoperation locking device, comprise the shell 1 for covering tapered end 7, the switch lock of the cabinet door 6 that tapered end 7 is switchboard.The outer face of shell 1 and all opening settings of half of upper surface, connect a jointed shaft 2 at shell 1 upper surface medium position, described jointed shaft 2 connect for closure 1 open end renovate 3, renovate 3 be inverted L shaped.The outer face of shell 1 and upper surface be opening all, can enlarge inlet-duct area, is conducive to operating personnel's operation.Renovate 3 length and will stretch out outside shell 1, renovate 3 bottoms and stretch out in the outer part of shell 1 and offer a strip hole 4, described shell 1 bottom is fixedly connected with a junction plate 51, offers the through hole 511 with hole 4 opposite positions on described junction plate 51; Then pass hole 4 and through hole 511 with lock body 5, will renovate 3 and lock together with shell 1 closure.Lock body 5 is puzzle lock, needs special encoder, just can open lock body.On the rear plate 11 of shell 1, offer as can see from Figure 2 for the through-core hole 12 through tapered end 7.Rear plate 11 is fixedly connected with by screw with the cabinet door 6 of transformation cabinet.

Shell 1 can also be connected with the tapered end 7 of transformation cabinet as can see from Figure 3.The person that like this do not avoid theft directly dismantles cabinet door 6 and destroys blocking device.Be fixedly connected with a block 71 on rear plate 11, block 71 and tapered end 7 keeping parallelisms, connect the contiguous block 72 arranged perpendicular to tapered end 7 on block 71, connect the slide block 73 that width is greater than contiguous block 72 width on contiguous block 72, offer groove 75 and chute 751 on described tapered end 7, described contiguous block 72 is in the interior motion of groove 75, and described slide block 73 is in the interior operation of chute 751.The width of described groove 75 is less than the width of chute 751.Groove 75 can prevent that limited slip block 73 comes off away like this.Offer a dismounting mouth 74 that can break away from chute 751 for slide block 73 on groove 75, for for convenience detach blocking device, so be provided with dismounting mouth 74, can extract for slide block 751.Stealer is generally when seeing blocking device, and the first reaction is first firmly to pull out, looks to pry open.Sometimes be difficult to expect going to rotate blocking device as driving safety cabinet.And dismounting mouth 74 can be arranged on to the certain position of tapered end 7, convenient operation person oneself memory.

Can also see that from Fig. 2 and Fig. 4 renovating 3 arranges weather strip 8, renovate 3 with shell 1 closure after, weather strip 8 can fit tightly the inwall of shell 1 port.For increasing renovate 3 and shell 1 between sealing, play good waterproof action, avoid tapered end 7 to contact with the direct of extraneous rainwater.
