Abstract

The utility model provides a novel anti-theft water grate which comprises a water grate shell, internal threads of the water grate shell, an internally-extending edge of the water grate shell, a water grate cover body with threads, external threads of the water grate cover body with the threads and a buckle. When the anti-theft water grate is used, the water grate cover body with the threads only needs to be screwed firmly with the water grate shell through the internal threads of the water grate shell and the external threads of the water grate cover body with the threads. Because the internally-extending edge of the water grate shell is arranged at the edge of the upper part of the water grate shell, the diameter of the water grate cover body with the threads is larger than the diameter of a well head, so the water grate can be thoroughly limited to be taken out from the well head, and thereby the anti-theft purpose is realized.

Description

The novel anti-theft leaf grating for down pipe

Technical field the utility model relates to leaf grating for down pipe, directly relates to the novel anti-theft leaf grating for down pipe.

Background technology is in urban construction, and block, road surface, square etc. all need draining, this just need leave a lot of catch pits, and leaf grating for down pipe must be installed on the catch pit, and traditional leaf grating for down pipe is by steel casting, since there is not anti-theft feature, often stolen, caused waste on the one hand, also brought public safety hidden danger simultaneously, though the leaf grating for down pipe that has is provided with lockhole, can lock,, lockset is easy to be pried open, and stolen phenomenon still difficulty is avoided.

The summary of the invention the purpose of this utility model will provide a kind of novel anti-theft leaf grating for down pipe exactly, and it can effectively solve the stolen problem of leaf grating for down pipe.

The purpose of this utility model is achieved in that the novel anti-theft leaf grating for down pipe, has to prolong edge, band silk leaf grating for down pipe lid, the outer silk of band silk leaf grating for down pipe lid and attacker in leaf grating for down pipe shell, leaf grating for down pipe shell internal thread, the leaf grating for down pipe shell.When mounted, the leaf grating for down pipe shell is embedded into the precalculated position, simultaneously, will be with silk leaf grating for down pipe lid to put into its inside, will be with silk leaf grating for down pipe lid and leaf grating for down pipe shell to screw and both can by leaf grating for down pipe shell internal thread and the outer silk of band silk leaf grating for down pipe lid.Prolong the edge owing to being provided with in the leaf grating for down pipe shell, make band silk leaf grating for down pipe lid diameter, taken out by well head, really play antitheft purpose so can thoroughly limit leaf grating for down pipe greater than the well head diameter at leaf grating for down pipe shell upper edge.

Description of drawings Fig. 1 is the leaf grating for down pipe outer casing construction drawing of the antitheft leaf grating for down pipe of the utility model, and Fig. 2 shows the structure chart of band silk leaf grating for down pipe lid, and the utility model is described in further detail below in conjunction with accompanying drawing.

Specific embodiment Fig. 1 shows the utility model novel anti-theft leaf grating for down pipe outer casing construction drawing, have and prolong edge 2, leaf grating for down pipe shell internal thread 3 in leaf grating for down pipe shell 1, the leaf grating for down pipe shell, Fig. 2 shows the structure of the antitheft leaf grating for down pipe lid of the utility model, has band silk leaf grating for down pipe lid 4, the outer silk 5 of band silk leaf grating for down pipe lid and attacker 6.When mounted, leaf grating for down pipe shell 1 is embedded into the precalculated position, simultaneously, to be with silk leaf grating for down pipe lid 4 to put into its inside, catch attacker 6 with hand, band silk leaf grating for down pipe lid 4 is screwed by the outer silk 5 of band silk leaf grating for down pipe lid on leaf grating for down pipe shell internal thread 3 and the band silk leaf grating for down pipe lid 4 with leaf grating for down pipe shell 1 both can.Prolong edge 2 in the leaf grating for down pipe shell owing to being provided with, make band silk leaf grating for down pipe lid 4 diameters, taken out by well head so can thoroughly limit leaf grating for down pipe greater than well head in leaf grating for down pipe shell 1 top edge.
