Specific embodiment

Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.

Referring to figure 1 and figure 2, Fig. 1 is the structural schematic diagram of the embodiment of the application；Fig. 2 is the explosive view of Fig. 1.

The hermetically-sealed instrument box of the easily assembling of the present embodiment includes box body 1, sealing ring 2 and lid 3.

Box body 1 is formed by metal plate punching.Box body 1 includes two and is mutually isolated and the first opening up cavity 11 and second Cavity 12.First cavity 11 is used for the circuit board to install instruments, first cavity 11 and sealing ring 2 and lid 3 forms one A confined space, to completely cut off corrosive reagents protection circuit plate.Shown in Figure 3, Fig. 3 is that the structure of box portion is shown It is intended to.First cavity, 11 side is equipped with a vertical flanged plate 111 upward, and flanged plate 111 is equipped with threaded hole 112.Flange Plate 111 can enhance bonding strength.

Sealing ring 2 is to constitute with certain elastomeric material.The sealing ring 2 is sealed in first cavity 11 Be open surrounding.

Lid 3 is mounted on the first cavity 11 and presses the sealing ring 2.The lid 3 include lid main body 31 and Fastening strip 32.Lid main body 31 is sealed on the first cavity 11, and 32 stress of fastening strip is pressed into first cavity, reaches precompressed The function of locking.It is as shown in Figure 4 and Figure 5:

31 lower surface of lid main body is equipped with the stud 311 with screw hole, and the fastening strip 32 passes through screw and the spiral shell Stake 311 is locked, as shown in Figure 4.The fastening strip 32 is made of metal plate, and the fastening strip 32 includes fixed bar 321 and card Detain slanted bar 322, the buckle slanted bar 322 at a certain angle with the fixed bar 321 is inclined is wholely set, the buckle is tiltedly Deformation is generated after 32 stress of item to be pressed into first cavity 11.The side of the lid main body 31 is equipped with through-hole 312, the lid Phosphor bodies 31 pass through the threaded hole 112 on the through-hole 312 and the flanged plate 111 by screw and fix with the box body 1, with Just increase the bonding strength of box body 1 and box cover 3.

In addition, the seal groove 33 is for limiting as shown in figure 5, the bottom surface of the side of the box cover 3 offers seal groove 33 The sealing ring 2 is made, installation is prevented to be not good at the problem of causing sealing ring 2 to expose.

The installation method of the hermetically-sealed instrument box of the utility model are as follows: first connect lid main body 31 and fastening strip 32 by screw It connects, then sealing ring 2 is pressed into seal groove 33.Then fastening strip oblique cutting is entered in box body 1, lid 3 is pushed, finally by spiral shell Nail will be on lid 3 and the connection of box body 1.

The application ensure that the reliability of precompressed and sealing by seal groove and prepressing structure.By designing buckle structure, Rear portion only needs 2 screws to fix, and simplifies structure, convenient for inserting assembly and disassembly.

Embodiments described above is merely to illustrate the utility model rather than limitation the scope of the utility model.This The equivalent changes and modifications that field technical staff does the utility model all should belong to the utility model the attached claims The covering scope of book.
