Abstract
The utility model relates to a casing of a global position system (GPS) gauge main machine, which comprises a top half casing and a base half casing. The connection position of the upper half casing and the lower half casing adopts curve design, and the top half casing and the base half casing can be simply fixed through screws. Compared with the traditional design, the casing is simple in structure, reduces the casing portion, and enables parts installed in the casing to be easily assembled and disassembled. The curve design increases openness of GPS internal parts and improves convenience in use and maintenance. Only one O-shaped sealing ring is required for sealing. Compared with the traditional double-face sealing ring, sealing performance of the casing is better to control.
Description
Technical field
The utility model belongs to electronic device field, especially relates to a kind of GPS measuring instrument host shell.
Background technology
The GPS measuring instrument is the location, navigation, one of visual plant in the Exploration Domain.And the host shell of GPS measuring instrument is the critical component of protection GPS measuring instrument electronic equipment; General three partial design that adopt of traditional GPS measuring instrument host shell are made up of base, housing and top cover.The design of this three parts is owing to want firm banking and top cover to housing, and difficulty is all compared in assembling and dismounting.The part that can only detect the top behind the top cover is opened in this design simultaneously; And installing/dismounting part difficulty; The more complicated of safeguard, and traditional GPS measuring instrument host shell to adopt the two sides be the design of the O-ring seal on plane, the sealing of bad main control system housing.
Summary of the invention
The purpose of the utility model is to propose a kind of GPS measuring instrument host shell, and housing has adopted the structure of two halves formulas promptly to push up half shell and base half shell, and its sealing surface is a kind of diagonal angle curved surface.With respect to the project organization (base, housing and top cover) of three traditional parts, the utility model is convenient to the assembling and the dismounting of parts in the housing more.
To achieve these goals; The technical scheme of the utility model is: a kind of GPS measuring instrument host shell; Said housing is that six square square casing is arranged; Said housing comprises top half shell and base half shell, and housing pushes up half shell and base half shell front and back side interface and is in respectively on the square casing on the half side and following half side surface level, and housing pushes up that interface and right side interface are the inclined-planes, diagonal angle that is connected with front and back side interface on the left of half shell and base half shell; Interface around said base half shell is provided with groove, in groove, is placed with the cross section and is circular O shape circle.
Inclined-plane, said diagonal angle is curved of diagonal angle.
The beneficial effect of the utility model is: saved traditional main casing, and simple in structure, be convenient to the assembling and the dismounting of enclosure interior part more.After the curve design of two halves shell surface of contact makes that upper half shell is opened about the GPS measuring instrument host shell; Most part all exposes in sight; The difficulty of repair and maintenance is reduced greatly, and the technical scheme that seals with an O shape circle between two halves shell surface of contact makes the better tightness control of GPS measuring instrument host shell.
Below in conjunction with accompanying drawing and embodiment the utility model is made a detailed description.
Description of drawings
Fig. 1 is the utility model decomposition texture synoptic diagram;
Fig. 2 is the utility model assembling back casing synoptic diagram.
Embodiment
A kind of GPS measuring instrument host shell embodiment; Referring to Fig. 1 and Fig. 2; Housing is a square casing that has six square; Said housing comprises top half shell 1 and base half shell 2, and housing pushes up before and after half shell and base half shell side interface 2-1 and 2-2 and is in respectively on the square casing on the half side and following half side surface level, and housing pushes up that interface 2-3 and right side interface 2-4 are the inclined-planes, diagonal angle that is connected with front and back side interface on the left of half shell and base half shell; Interface around said base half shell is provided with groove, in groove, is placed with the cross section and is circular O shape circle 3.
Can there be various ways on the inclined-plane at left and right sides interface diagonal angle; Purpose is dismounting and the debugging that makes things convenient for the enclosure interior part; Simultaneously can realize good sealing again, so it promptly can be that the diagonal angle straight slope also can be a kind of diagonal angle arc surface, inclined-plane, the said diagonal angle of present embodiment is curved of diagonal angle.
Experiment showed, present embodiment owing to there is not a traditional housing, only need up and down two parts to be fixed together and get final product, assemble easily and dismantle.The structure of two halves formula, after opening loam cake, most parts all expose in sight, have made things convenient for the repair and maintenance in the use.The design of two halves formula only needs an O type circle to solve the sealing problem of faying face, and sealing property is better controlled.
Claims (2)
1. GPS measuring instrument host shell; Said housing is that six square square casing is arranged; Said housing comprises top half shell and base half shell; It is characterized in that housing pushes up before and after half shell and base half shell interface of side and is in respectively on the square casing on half side and the following half side surface level, housing pushes up that interface and right side interface are the inclined-planes, diagonal angle that is connected with front and back side interface on the left of half shell and base half shell; Interface around said base half shell is provided with groove, in groove, is placed with the cross section and is circular O shape circle.
2. a kind of GPS measuring instrument host shell according to claim 1 is characterized in that inclined-plane, said diagonal angle is curved of diagonal angle.
