A kind of mechanical lock rain cover of the present utility model, be located on the mechanical lock, the lock bridge that mechanical lock comprises lock body, is flexibly connected with this lock body, described rain cover is installed in the lock bridge place of mechanical lock, lock bridge partly exposes this rain cover, this rain cover covers whole lock body, and described rain cover comprises the top that is ramped shaped, be positioned at top offers first, second perforate, and the bottom of this rain cover is open type.

Wherein, described lock bridge comprises that activity is installed in the first vertical portion of lock body, can be locked in the second vertical portion, the bend between the first vertical portion and the second vertical portion of lock body, the top of described rain cover is installed in first, second place, vertical portion of lock bridge, and the bend of lock bridge exposes rain cover.

Wherein, the top of rain cover the second perforate of being provided with first perforate of being passed by the first vertical portion, being passed by the second vertical portion.

Wherein, be provided with the sealing device of being made by elastomeric material around described first, second perforate.

Wherein, described rain cover is the square shape.

Wherein, the relative two sides of described rain cover are equipped with some air-vents.

Wherein, the air-vent of described each side is two.

The beneficial effects of the utility model are, this rain cover is located on the mechanical lock, this rain cover is the lock bridge place that is installed in mechanical lock, lock bridge partly exposes this rain cover, and this rain cover covers whole lock body, can prevent that so not only rainwater from entering lock core and lock body, and the recessive defective of cancellation element, the Improving Equipment service efficiency, the application reliability, the flexibility that improve mechanical lock reduce the unlocking operation number of times.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of manual, and for above-mentioned and other objects, features and advantages of the present utility model can be become apparent, below especially exemplified by embodiment, and the cooperation accompanying drawing, be described in detail as follows.

Fig. 2 is the another structural representation of this mechanical lock rain cover;

Fig. 3 is another structural representation of this mechanical lock rain cover.

The specific embodiment

Be to reach technological means and the effect that predetermined utility model purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, the rain cover specific embodiment, structure, feature and effect thereof to according to the mechanical lock that the utility model proposes are described in detail as follows:

Relevant aforementioned and other technology contents of the present utility model, Characteristic can be known to present in the following detailed description that cooperates with reference to graphic preferred embodiment.Explanation by the specific embodiment, when can being to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the utility model, yet appended graphic only provide with reference to the usefulness of explanation, the utility model is limited.

Mechanical lock of the present utility model is for transformer station, because transformer station all adopts mechanical lock with crypto chip for breaker cabinet door, isolating switch (comprising grounding switch) operating handle, earth terminal and various net doors etc., the principle of mechanical lock is identical with the cable of general family expenses, such as Fig. 1, mechanical lock 10 comprises that the top of lock body 11, lock body 11 is provided with first,

second keyhole

12,13, is locked in this first, second keyhole 12, the lock bridge 14 in 13 and the bottom of lock body 11 are provided with the eye 15 of unblanking.This lock bridge 14 comprises: activity is installed in the first vertical portion 141 of lock body 11, second vertical portion 143 that can be locked in lock body 11, the bend 142 between the first vertical portion 141 and the second vertical portion 143, and the free end activity of the first vertical portion 141 of lock bridge 14 is installed in the first keyhole 12, the free end of the second vertical portion 143 of lock bridge 14 can be locked in the second keyhole 13, lock bridge 14 is used for interlock, reaches the effect of the pinning of mechanical lock 10.Because first,

second keyhole

12,13 leaves certain space with first, second vertical portion 141,143 of lock bridge 14 respectively, and eye 15 long-term the leakages outside of unblanking, being very easy to make rainwater to enter mechanical lock inside causes lockset to get rusty, impact is unblanked, so the rain cover of mechanical lock of the present utility model is just for the recessive defective of cancellation element, the Improving Equipment service efficiency, the application reliability, the flexibility that improve mechanical lock reduce the unlocking operation number of times and set up.
