Embodiment

The utility model is described in further detail below in conjunction with embodiment, but structure of the present utility model is not limited only to following examples:

[embodiment 1]

As shown in Figure 1, be applied to the dustproof and waterproof lock construction of distribution box, comprise lock body, described lock body is arranged in the groove 9 in distribution box chamber door 4 outsides, and groove 9 is outside equipped with groove lid 10, and groove lid 10 is hinged on the chamber door 4.

[embodiment 1]

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, be applied to the dustproof and waterproof lock construction of distribution box, comprise lock body, described lock body is arranged in the groove 9 in distribution box chamber door 4 outsides, and groove 9 is outside equipped with groove lid 10, and groove lid 10 is hinged on the chamber door 4.

The lock body of present embodiment comprises rotation clamping stagnation device 7 and lock ear 5.

Described rotation clamping stagnation device comprises rotating shaft 1, handle 2 and block tongue 3, described rotating shaft 1 rotation is installed on the chamber door 4, rotating shaft 1 runs through chamber door 4, rotating shaft 1 is positioned at the end fixed installation block tongue 3 of chamber door 4 inboards, block tongue 3 is strip, its bearing of trend is vertical with rotating shaft 1, and rotating shaft 1 is positioned at an end hinged handle 2 in chamber door 4 outsides, and the length of handle 2 is greater than the distance of lock ear 5 to handle 2 pin joints.

The plane of rotation of described handle 2 is vertical with the bearing of trend of block tongue 3, lock ear 5 be positioned at rotate clamping stagnation device 7 under.

Described handle 2 is provided with and locks the lock earhole 6 that ear 5 cooperates, and lock earhole 6 is consistent to the distance values of handle 2 pin joints with lock ear 5 to the distance of handle 2 pin joints, makes that the lock earhole 6 on the handle 2 can overlap the ear 5 of locking.

Described lock ear 5 is provided with lockhole 11, lockhole 11 arrives the thickness of the distance of chamber door 4 greater than handle 2, and when promptly handle 2 was inserted in lock ear 5, lockhole 11 was exposed at the outer end of handle 2, at this moment add at lockhole 11 places that padlock promptly can lock handle 2, thereby limit the rotation of handle 2.
