The utility model discloses a following technical scheme realizes above-mentioned purpose, a waterproof construction of passive photoelectricity direct-reading meter watchcase for watchcase structure's is waterproof, watchcase structure is assembled by drain pan and shell cover plate and is constituteed, the drain pan with the one side of shell cover plate contact sets up the round and centers on the shell edge board of drain pan, the shell edge sets up the concatenation recess on the board, set up on the shell cover plate with concatenation recess assorted concatenation lug, the concatenation lug with it has the rubber packing ring still to fill between the concatenation recess.

Preferably, the shell cover plate and the shell edge plate are both provided with bolt holes, and the bottom shell and the shell cover plate are assembled through fixing bolts.

Preferably, the splicing groove is arranged in a circle around the storage cavity of the bottom shell.

Preferably, the shell edge plate is further provided with a diversion trench, and the splicing groove is formed between the diversion trench and the bottom shell.

Preferably, a plurality of through holes are formed in the diversion trench.

Preferably, the top position of the diversion trench is lower than the top position of the splicing groove.

Compared with the prior art, the beneficial effects of the utility model are that: the assembled shell structure adopts a mode of inserting a lug and a groove, and a rubber gasket is filled between the splicing lug and the splicing groove, so that the assembling sealing performance is greatly improved, and rainwater is effectively prevented from entering the shell along a gap of the shell structure to damage the internal electronic module; the circle of the diversion grooves are formed in the periphery of the bottom shell, and the diversion grooves are lower than the assembling grooves, so that rainwater can flow into the diversion grooves firstly, and the through holes are formed in the diversion grooves and used for draining water, so that rainwater is prevented from accumulating in the diversion grooves, and the waterproof effect is enhanced.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figures 1-4, a waterproof structure of a passive photoelectric direct-reading meter case is used for waterproofing of a case structure 1, the case structure 1 is formed by assembling a bottom case 5 and a case cover plate 3, one surface of the bottom case 5, which is contacted with the case cover plate 3, is provided with a circle of case edge plate 4 surrounding the bottom case 5, the case edge plate 4 is provided with a splicing groove 9, the case cover plate 3 is provided with a splicing lug 11 matched with the splicing groove 9, a rubber gasket 10 is filled between the splicing lug 11 and the splicing groove 9, the case structure 1 is convenient to disassemble by adopting the mode of assembling the bottom case 5 and the case cover plate 3, an internal electronic module is overhauled, when the case structure 1 is assembled, the splicing lug 11 on the case cover plate 3 is inserted into the splicing groove 9 of the case edge plate 4, and the assembled gap between the splicing lug and the splicing groove is sealed by filling the rubber gasket 10, thereby effectively preventing rainwater from entering, and carrying out waterproof protection on the electronic module. All set up bolt hole 6 on shell cover plate 3 and the shell edge board 4, drain pan 5 and shell cover plate 3 assemble through fixing bolt 2, and watchcase structure 1 adopts shell cover plate 3 and drain pan 5 to assemble the back, fixes by fixing bolt 2 again, makes it make things convenient for the dismouting, and concatenation recess 9 sets up the round around the storing cavity of drain pan 5, and concatenation recess 9 that sets up the round makes rubber packing ring 10 surround the storing cavity, prevents that the rainwater from getting into storing cavity.

The shell edge plate 4 is also provided with a diversion trench 7, the splicing groove 9 is arranged between the diversion trench 7 and the bottom shell 5, the diversion trench 7 has the function of diversion, as the splicing groove 9 is positioned between the bottom shell 5 and the diversion trench 7, when rainwater exists, the rainwater firstly flows into the diversion trench 7, the diversion trench 7 can be contacted with the splicing groove 9 when overflowing, a plurality of through holes 8 are arranged inside the diversion trench 7, when the through holes 8 inside the diversion trench 7 have accumulated water in the diversion trench 7, the redundant accumulated water can be discharged, thus the accumulated water can be prevented from permeating into the bottom shell 5, the rainwater can not permeate into the watchcase structure 1 to greatly improve the waterproof effect even if more rainwater is present, the top position of the diversion trench 7 is lower than the top position of the splicing groove 9, the diversion trench 7 can be contacted with the splicing groove 9 only if overflowing more diversion trench 7, but the accumulated water in the diversion trench 7 can be continuously discharged from the through holes 8, therefore, the bottle-packed gap between the splicing groove 9 and the splicing lug 11 contacted by rainwater is reduced, and the water resistance is facilitated.
