Abstract
The utility model discloses a laser diameter measuring instrument's circuit board fixing device, including the box, be equipped with the recess that supplies the determinand to pass through on the box, be equipped with in the box rather than the perpendicular circuit board that sets up, the circuit board both sides are fixed on the support of two perpendicular settings with the box, and the support center is equipped with the screw hole, is equipped with the straight straight flute that runs through the screw hole on the support, the straight flute runs through the support, the both sides of circuit board are equipped with the flange of high reduction, the flange stretches into in the straight flute, the threaded hole spiro union has the screw, the screw crimping has the gasket, and the top of flange and the top of support flush, the top of flange part butt gasket, the both sides butt threaded hole's of flange screw. The utility model discloses an it is less that laser diameter measuring instrument's circuit board fixing device makes the circuit board occupy the box space, and the installation is dismantled conveniently and can not caused the circuit board impaired, and the radiating effect is good.
Description
Technical field
This utility model relates to laser diameter measuring instrument technical field, especially relates to the circuit of a kind of laser diameter measuring instrument
Board fixer.
Background technology
Laser diameter measuring instrument is for measuring the diameter dimension of determinand, the casing of laser diameter measuring instrument the most on the market
Interior wiring board is arranged for " lying low ", i.e. wiring board and casing be arranged in parallel, and this setting makes wiring board account for
With space more in casing, although the bottom surface of wiring board and box body wall keep apart a segment distance for strengthening
Heat radiation, but actually radiating effect also has the space promoted, and wiring board " lies low " and need to use screw when arranging
It is fixed directly through wiring board, wiring board the most firmly can be caused when sometimes twisting screw impaired, be badly in need of changing
Enter.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of laser diameter measuring instrument
Circuit board fixing device so that it is less that wiring board takies cabinet space, easy installation and removal and do not result in line
Road plate is impaired, good heat dissipation effect.
For reaching above-mentioned purpose, the technical solution of the utility model is: the wiring board of a kind of laser diameter measuring instrument is solid
Determining device, including casing, described casing is provided with the groove passed through for determinand, be provided with in described casing with
Its vertically disposed wiring board, described wiring board both sides be fixed on two with the vertically disposed bearing of casing on,
Described bearing center is provided with screwed hole, and bearing is provided with the straight trough running through screwed hole straight, and described straight trough runs through
Bearing, the both sides of described wiring board are provided with the flange of height reduction, and described flange stretches in straight trough, described spiral shell
Being bolted with screw in pit, described screw is crimped with pad, the top of described flange and the top of bearing and flushes,
The tip portion of flange abuts pad, the screw in the both sides joining threaded hole pit of flange.
The beneficial effects of the utility model are: be vertically arranged with casing by wiring board, and wiring board takies casing
Internal space is less, and improves radiating effect, and wiring board is by the outside joining threaded hole of the flange of its both sides
Nail, the top of flange abuts pad, easy installation and removal and not result in wiring board impaired.

Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is made the most concrete
Explanation.
As shown in Figure 1 to 4, the circuit board fixing device of a kind of laser diameter measuring instrument, including casing 1, described
Casing 1 is provided with the groove 3 passed through for determinand 2, is provided with the circuit of perpendicular setting in described casing 1
Plate 5, described wiring board 5 both sides be fixed on two with the vertically disposed bearing of casing 14 on, described bearing 4
Center is provided with screwed hole 6, and screwed hole 6 is also vertical with casing 1, and bearing 4 is provided with and runs through screwed hole 6 straight
Straight trough 7, straight trough 7 is also vertical with casing 1, and described straight trough 7 runs through bearing 4, i.e. screwed hole 6 both sides are each
Having one section of straight trough 7, this utility model can install multiple wiring board 5 according to the actual requirements, three bearings 4 in
Two wiring boards 5 can be installed in adjacent position during one linear array, a bearing 4 can be saved.
The both sides of described wiring board 5 are provided with the flange 10 of height reduction, and described flange 10 stretches in straight trough 7,
Being bolted with screw 9 in described screwed hole 6, described screw 9 is crimped with pad 8, and screw 9 can be divided into upper end
Head of screw and the shank of screw of lower end, pad 8 be really crimped on the screwed hole 6 of bearing 4 top and
Between head of screw, the top of described flange 10 and the top of bearing 4 flush, and the tip portion of flange 10 is supported
Connection pad sheet 8, i.e. limits the movement of the horizontal Y direction of wiring board 5, and the both sides of flange 10 abut screw thread
Screw 9 in hole 6, on the actual shank of screw being connected in screwed hole 6 in the both sides of flange 10, i.e. limits
The axial movement of horizontal X of wiring board 5, can be designed to the thickness of flange 10 and straight trough 7 simultaneously
Thickness is identical, i.e. limits the movement of the vertical Z-direction of wiring board 5.
The above, only this utility model preferably detailed description of the invention, but protection model of the present utility model
Enclose and be not limited thereto, the technology model that any those familiar with the art discloses at this utility model
In enclosing, the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
