Abstract
The present invention is to solve tester long-time storing to will lead to dust stratification in test panel, occurs the technical issues of short circuit phenomenon in experiment and provides a kind of tester dust guard.The technical solution used in the present invention is: a kind of tester dust guard, including experimental box and dustcloth；The experimental box is surrounded by a circle guide rail；The guide rail section is in the rectangle of upper surface middle opening；The dustcloth quadrangle is connected with guide post；It is described to lead intercolumnar distance to four angular separation of guide rail from corresponding；The guide post bottom end is protruded into guide rail, is equipped with annular groove with guide openings corresponding position；The guide post can be moved along the guide rail.When tester for a long time when not used, guide post is moved to guide rail four corners along guide rail, dustcloth will test upper box part covering, avoid dust from falling in and cause short circuit in test panel；When tester needs to test, 4 guide posts are moved on into the same side, exposes experimental box, does not influence to test.The configuration of the present invention is simple, it is light small and exquisite unheavy.
Description
Technical field
The present invention relates to a kind of dust guards, more particularly to a kind of tester dust guard.
Background technique
For tester using especially extensively in electronic instruction, existing tester is experimental box body its top end face mostly
For test panel, experimental circuit is overlapped for student.Due to test panel outdoor layout, so tester is put for a long time to lead
Dust stratification in test panel is caused, dust will lead to dust stratification in the test jack in test panel, so as to cause may be because in experiment
Occur short circuit for dust, influences the accuracy of experiment and the service life of experimental box.
Summary of the invention
The present invention is to solve tester long-time storing to will lead to dust stratification in test panel, short circuit phenomenon occurs in experiment
Technical problem and a kind of tester dust guard is provided.
The technical solution used in the present invention is: a kind of tester dust guard, including experimental box and dustcloth；The reality
Tryoff is surrounded by a circle guide rail；The guide rail section is in the rectangle of upper surface middle opening；The dustcloth quadrangle is connected with
Guide post；It is described to lead intercolumnar distance to four angular separation of guide rail from corresponding；The guide post bottom end is protruded into guide rail, with guide openings
Corresponding position is equipped with annular groove；The guide post can be moved along the guide rail.When tester for a long time when not used, by guide post along leading
Rail is moved to guide rail four corners, and dustcloth will test upper box part covering, and avoid dust from falling in and cause short circuit in test panel；Work as examination
When testing instrument and needing to test, 4 guide posts are moved on into the same side, exposes experimental box, does not influence to test.The configuration of the present invention is simple, volume
Small, light weight is not light small and exquisite heavy.
In order to not touch test panel during dustcloth is covered and pulled open, and experiment face is entirely fallen within after covering
On plate, the guide post includes the lower prop protruded into the guide rail and covers on the outside of the lower prop for connecting the dustcloth
Cylinder；The upper cylinder inner wall is equipped with ratchet；The upper cylinder two sides are respectively provided with an axial bar hole；Fluting, slot among the lower prop
The ratchet that side wall is equipped with button and matches with the upper cylinder inner wall ratchet；The button is stretched out from the strip-shaped hole.
In order to reduce frictional resistance during guide post moves along the rail, the guide post bottom end is equipped with idler wheel.
As a further improvement, the guide rail quadrangle is provided inwardly with arc positioning port.When tester for a long time when not used, will
Guide post is placed at positioning port, is easy positioning and is not easy voluntarily to slide, stability is more preferable.
Preferably, the dustcloth is detachably connected with the guide post.When dustcloth is dirtier, can disassemble into
Row cleaning.
The advantages and positive effects of the present invention are: since the present invention uses technical solution as above, when tester is long
Between when not used, guide post is moved to guide rail four corners along guide rail, dustcloth will test upper box part covering, and dust is avoided to fall in experiment
Cause short circuit on panel；When tester needs to test, 4 guide posts are moved on into the same side, exposes experimental box, does not influence to test.
In addition, the present invention also has structure simple, production cost is low, small in size, light weight, light small and exquisite unheavy advantage.
In addition to it is described above present invention solves the technical problem that, constitute technical solution technical characteristic and by these
Except advantage brought by the technical characteristic of technical solution, other technologies problem that the present invention can solve is wrapped in technical solution
Advantage brought by the other technical characteristics contained and these technical characteristics, makees further details of hereinafter in conjunction with attached drawing
Explanation.
Detailed description of the invention
Fig. 1 is tester dust guard structural schematic diagram of the present invention；
Fig. 2 is guide post schematic cross-sectional view；
Fig. 3 is guide rail overlooking structure diagram.
In figure: 1, experimental box；2, dustcloth；3, upper cylinder；4, strip-shaped hole；5, lower prop；6, guide rail；7, button；8, idler wheel；9,

Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and cooperate attached drawing
Detailed description are as follows:
As shown in Figure 1, the present embodiment is a kind of tester dust guard, including experimental box 1 and dustcloth 2；The experiment
Case 1 is surrounded by a circle guide rail 6；6 section of guide rail is in the rectangle of upper surface middle opening；2 four jiaos of the dustcloth is removable
It unloads and is connected with guide post；It is described to lead intercolumnar distance to four angular separation of guide rail from corresponding；The guide post bottom end is protruded into guide rail, with
Guide openings corresponding position is equipped with annular groove；The guide post bottom end is equipped with idler wheel 8；The guide post can be moved along the guide rail.
As shown in Fig. 2, the guide post includes the lower prop 5 protruded into the guide rail and covers on the outside of the lower prop 5 for connecting
Connect the upper cylinder 3 of the dustcloth 2；3 inner wall of upper cylinder is equipped with ratchet 9；3 two sides of upper cylinder are respectively provided with an axial bar hole
4；It slots among the lower prop 5, the ratchet 9 that groove sidewall is equipped with button 7 and matches with the upper 3 inner wall ratchet 9 of cylinder；It is described to press
Button 7 is stretched out from the strip-shaped hole 4.
As shown in figure 3,6 four jiaos of the guide rail is provided inwardly with arc positioning port 10.
The course of work of the invention are as follows: when tester for a long time when not used, above pull on cylinder so that dustcloth be higher than experimental box
Upper surface；Guide post is moved to guide rail four corners along guide rail, dustcloth will test upper box part covering；Pin button, cylinder in pushing,
So that dustcloth is attached on experimental box, avoids dust from falling in and cause short circuit in test panel；When tester needs to test, pull-up
Upper cylinder, so that dustcloth is higher than experimental box upper surface；4 guide posts are moved on into the same side, exposes experimental box, does not influence to test.
The embodiments of the present invention have been described in detail above, but content is only the preferred embodiment of the present invention,
It should not be considered as limiting the scope of the invention.Any changes and modifications in accordance with the scope of the present application,
It should still be within the scope of the patent of the present invention.
