Description
Technical field
The utility model relates to gas detecting instrument technical field, in particular to a kind of gas detecting instrument upper casing.
Background technique
The pcb board of existing gas detecting instrument is all mounted in behind upper casing, is directly connected to pcb board by screw
In fixed column, be easy to need artificial device to hole during the installation process, i.e., the connecting hole of pcb board and the connecting hole of fixed column to it is upper again
It screws, and is easy to appear other hole location dislocation during screwing, device to hole again in need thus will increase group
ETL estimated time of loading increases cost of labor.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of gas detecting instrument upper casings, solve gas detecting instrument group
The problem of ETL estimated time of loading length and high labor cost.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of gas detecting instrument upper casing, including shell, the housing forward end face are equipped with display mounting groove, the display
Device mounting groove is equipped with multiple display fixation holes, key hole and switch hole, and the housing rear end face is solid equipped with multiple pcb boards
Fixed column, each pcb board fixed column side are designed with a positioning column, each pcb board fixed column and corresponding positioning
It is connected between column by the first connecting plate.
Further, the housing rear end face is equipped with multiple upper casing connecting columns, and each upper casing connecting column side is designed with
The second connecting plate being connect with the shell.
Further, housing forward end face lower end is semicircular structure, and the edge of the semicircular structure front end face is equal
It is even to be equipped with multiple decoration holes.
Further, the shell two sides are designed with a plurality of anti-skid bulge.
Further, the shell lower end is equipped with USB connector.
It by adopting the above technical scheme, in this way can be with due to being equipped with the first connecting plate and positioning column in pcb board fixed column side
Pcb board is positioned in advance by positioning column, remove would not be cheap by PCB when screwing fixed pcb board in this way, improves assembling
Efficiency reduces cost of labor.
Detailed description of the invention

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Referring to figs. 1 to Fig. 3, a kind of gas detecting instrument upper casing provided by the utility model, including shell 4, before the shell 4
End face is equipped with display mounting groove 8, and the display mounting groove 8 is equipped with multiple display fixation holes 7, key hole 5 and opens
Hole 3 is closed, 4 rear end face of shell is equipped with multiple pcb board fixed columns 12, and each 12 side of pcb board fixed column is designed with
One positioning column 14 is connected between each pcb board fixed column 12 and corresponding positioning column 14 by the first connecting plate 13.
The technical program is equipped with the first connecting plate 13 and positioning column 14 in 12 side of pcb board fixed column, can pass through in this way
Positioning column 14 in advance positions pcb board, and pcb board would not be cheap when screwing fixed pcb board in this way, improves assembling effect
Rate reduces cost of labor.The needs of pcb board corresponding to the technical program offer the hole location matched with positioning column 14 in advance,
Each 14 upper end of positioning column is designed with chamfering so that it is convenient to which the hole location on positioning column 14 and pcb board cooperates.Pass through the first connecting plate
13 can prevent positioning column 14 from swinging, and improve pcb board packaging efficiency.4 upper end of shell is equipped with sensor installation port 10.
4 rear end face of shell is equipped with multiple upper casing connecting columns 10, and each 10 side of upper casing connecting column is designed with and institute
State the second connecting plate 9 of the connection of shell 4.The intensity of the connection of upper casing connecting column 10 can be increased in this way.
The 4 front end face lower end of shell is semicircular structure, and the edge of the semicircular structure front end face is uniformly provided with more
A decoration hole 1.Crystal decoration can be bonded in decoration hole 1 to bore, cooperation semicircular structure makes entirety seem more beautiful.
4 two sides of shell are designed with a plurality of anti-skid bulge 6.Facilitate taking for entire product in this way.
4 lower end of shell is equipped with USB connector 2.USB connector 2 is used for the connection of USB line.
In conclusion the utility model in this way may be used by being equipped with the first connecting plate and positioning column in pcb board fixed column side
Pcb board is positioned in advance by positioning column, remove would not be cheap by PCB when screwing fixed pcb board in this way, raising group
Efficiency is filled, cost of labor is reduced.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
