Abstract
The utility model relates to a protective cover of an outdoor isolation mechanism small-sized lock. The protective cover of the outdoor isolation mechanism small-sized lock comprises a work knob, an emergency unlocking hole, a lock rod hole, a rain-proof loop and a dead bolt. The protective cover of the outdoor isolation mechanism small-sized lock is characterized in that the rain-proof loop and a rain-proof lamp cover are arranged on the front of the protective cover, the emergency unlocking hole is formed in the rain-proof loop, a sealed thread cap is arranged on the emergency unlocking hole, a thread hole is formed in the rain-proof lamp cover, and the dead bolt is arranged on the back face of the protective cover. The lock rod hole is formed in the side face of the protective cover, a circular protrusion is arranged on the periphery direction of the lock rod hole, and the work knob is arranged on the top portion of the protective cover. The protective cover of the outdoor isolation mechanism small-sized lock has the advantages that rain-proof and dust-seal effects are good, and strength of the lock rod hole is high so that the deformation is not prone to occurring. Moreover, due to the fact that the protective cover is once compressed and poured to be formed through a mold, working efficiency is greatly promoted, cost is saved, the protective cover is novel in structure, beautiful and elegant in appearance, and smooth and neat.
Description
Technical field
The utility model relates to mechanical field, relates in particular to the protective cover of the small-sized lock of a kind of outdoor interrupter.
Background technology
The protective cover of the small-sized lock of present outdoor interrupter mainly comprises: function knob, emergency release hole, rainproof lampshade, reinforcement latch arm hole, dead bolt etc. partly form.The making of traditional industry is that square steel section bar cutting electric welding moulding is arranged, need to join hole, the rainproof lampshade circle that again lathe is processed, the rainproof circle of emergency release, install and fix bolt circle, function knob circle and carry out again argon welding, polishing, technique is very cumbersome, technical requirements is higher, and rainproof, envelope dirt poor effect, the not high easy generation distortion of latch arm hole intensity.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the protective cover of high strength, the small-sized lock of outdoor interrupter that reliability is high is provided, and its concrete technical scheme is as follows:
The protective cover of the small-sized lock of described outdoor interrupter comprises function knob, emergency release hole, latch arm hole, rainproof circle, dead bolt, the front of described protective cover is provided with rainproof circle and rainproof lampshade, described rainproof circle is built-in with the emergency release hole, Packed threaded cap is established in the emergency release hole, be provided with screwed hole in the described rainproof lampshade, the reverse side of described protective cover is provided with dead bolt, the side of protective cover is provided with latch arm hole, the projection that is circumferentially with annular of described latch arm hole, the top of protective cover is provided with described function knob.
The further design of the protective cover of the small-sized lock of described outdoor interrupter is that the inboard of described annular protrusion is provided with groove.
The further design of the protective cover of the small-sized lock of described outdoor interrupter is, being circumferentially with of described function knob one prolonged the radially-arranged slotted eye of function knob.
The protection advantage of the small-sized lock of outdoor interrupter that the utility model provides is as follows:
The protective cover of the small-sized lock of the outdoor interrupter of this outward appearance is that material is kirsite by injection-compression molding of mould, and the kirsite density ratio is higher, and is mobile more intense, and institute's pressure injection product out is relatively finer and smoother, and hardness ratio is than high.All appearance members once are embodied on the protective cover, and the emergency release hole has been prepared and has been with Packed threaded cap, has strengthened rainproof grade, and novel structure, elegant in appearance, smooth smooth has greatly improved operating efficiency, saved cost.
Description of drawings
Fig. 1 is the protective roof structure schematic diagram of the small-sized lock of described outdoor interrupter.
Fig. 2 is that the side of Fig. 1 is attempted
Among the figure, the rainproof circle of 1-, the rainproof lampshade of 2-, 3-latch arm hole, 4-annular protrusion, 5-function knob, 6-slotted eye, 7-dead bolt, 8-protective cover.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
Such as Fig. 1, the protective cover of the small-sized lock of outdoor interrupter that the utility model provides comprises function knob 5, the emergency release hole, latch arm hole 3, rainproof circle 1, dead bolt 7, the front of protective cover 8 is provided with rainproof circle and rainproof lampshade 2, rainproof circle 1 is built-in with emergency release hole (not shown in FIG.), Packed threaded cap is established in the emergency release hole, be provided with screwed hole in the rainproof lampshade 2, the reverse side of protective cover is provided with dead bolt 7, the side of protective cover is provided with latch arm hole 3, the projection 4 that is circumferentially with annular of latch arm hole 3, the inboard of this annular protrusion 4 is provided with groove, the top of protective cover is provided with function knob 5, and being circumferentially with of function knob 5 one prolonged the radially-arranged slotted eye of function knob.
The protective cover of the small-sized lock of this outdoor interrupter is that material is kirsite by injection-compression molding of mould, and the kirsite density ratio is higher, and is mobile more intense, and institute's pressure injection product out is relatively finer and smoother, and hardness ratio is than high.All appearance members once are embodied on the protective cover, and the emergency release hole has been prepared and has been with Packed rib-loop lid, has strengthened rainproof grade, and novel structure, elegant in appearance, smooth smooth has greatly improved operating efficiency, saved cost.
