Description
Technical field
The utility model is related to a kind of industrial thermometer, more particularly to a kind of mercurial thermometer.
Background technology
At present, conventional industrial thermometer generally comprise glass-stem thermometer, bimetallic thermometer, thermal resistance thermocouple with
And Double-metal thermoelectric hinders thermometer body etc..Wherein, due to glass-stem thermometer have the advantages that it is cheap, easy to use, according to
In being so widely used in industrial production and studying.It is well known that glass-stem thermometer is breakable after having collision or dropping
Shortcoming.During storage or transport, for reduce the broken situation of glass-stem thermometer it is general glass-stem thermometer add plastics or
Person's rubber protecting jacket.But taken when using glass-stem thermometer test temperature firstly the need of by glass-stem thermometer from protective case
Go out, then hand-held glass-stem thermometer, which contacts in its temperature-sensitive portion with object under test, can just draw temperature results after a period of time.By
Glass-stem thermometer does not have protection device usually to occur to crush after shakiness drops because hand is gripped in test process, therefore, it is necessary to
Exploitation it is a kind of in test process still have protection device glass-stem thermometer, particularly protect mercurial thermometer, mercury temperature
Degree meter, which drops, to be broken rear poisonous mercury into pieces and is difficult to collect complete, and the mercury of residual is volatile, is easily poisoned after Long Term Contact.
Utility model content
The purpose of this utility model is to provide a kind of mercurial thermometer, with being difficult to break into pieces after dropping during the use
Advantage.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of mercurial thermometer,
Including thermometer body, one end of the thermometer body, which is provided with outside temperature-sensitive portion, the thermometer body, is arranged with protective case,
The axial direction of thermometer body is provided with the waist-shaped hole for observing scale on the protective case, the protective case is close
The one end in temperature-sensitive portion is provided with the through hole stretched out for temperature-sensitive portion, and the thermometer body is arranged and consolidated in one end away from temperature-sensitive portion

The side of rubber cap is passed from waist-shaped hole.
By above-mentioned technical proposal, the setting of rubber cap top shoe one allows to the sliding block one by passage so that temperature
Count body to slide to the direction of through hole, and then cause temperature-sensitive portion to pass through hole, measure, reduce because of the direct pressure holding temperature of thumb
The situation that degree counts body and easily causes the crushing of thermometer body occurs.
Further, waist-shaped hole is located on the protective case and the both sides of the conflict of sliding block one offer chute one, it is described
The projection one matched with chute one is provided with sliding block one, the sliding block one is connected with protective case sliding.
By above-mentioned technical proposal, it is engaged by chute one with the upper protruding block one of sliding block one so that thermometer body is in passage
Or be difficult to swing during measurement so that thermometric process is more stablized.
Further, the protective case is provided with the stopper slot being embedded in for sliding block one positioned at the side of waist-shaped hole, when described
When sliding block one is embedded in stopper slot, through hole is stretched out in the temperature-sensitive portion.
By above-mentioned technical proposal, extension spring can be resisted to thermometer body by the way that sliding block one is embedded in stopper slot
The tractive force in through hole direction is directed away from, and then no longer to be continuously applied to thermometer body in continuous mode to be used for
Resist the active force of extension spring elastic force.
Further, the sliding block one is provided with projection two, the stopper slot in the side away from temperature-sensitive portion and is provided with
The neck matched with projection two.
By above-mentioned technical proposal, being cooperated by projection two and neck, it is spacing that sliding block one is stably embedded in
It is difficult to skid off in groove.
Further, radially it is arranged with annular catch on the protective case.
By above-mentioned technical proposal, the setting of annular catch makes thermometer body be difficult from waist-shaped hole to skid off protective case.
Further, the side on the outer wall of the protective case positioned at waist-shaped hole is provided with chute two, the annular catch
Inner side be provided with the sliding block two matched with chute two, annular catch scale in waist-shaped hole is set on corresponding position
There is magnifying glass.
By above-mentioned technical proposal, the setting of magnifying glass causes clearly observed temperature result, and passes through sliding block
Two allow the annular catch with magnifying glass to be slid up in the side axially in parallel with thermometer body with the cooperation of chute two
It is dynamic, so that the scale value for amplifying diverse location.
Further, the protective case outer surface is provided with some antiskid grooves in one end away from temperature-sensitive portion.
By above-mentioned technical proposal, the setting of antiskid groove is easy to this kind of mercurial thermometer to be convenient to gripping, increases and rubs
Wiping power causes thermometer to be difficult landing.
Further, it is provided with spongy layer between protective case and the thermometer body.
By above-mentioned technical proposal, spongy layer is set to enhance the protection of protective case between protective case and thermometer body
Effect.
In summary, the utility model has the advantages that：
After mercurial thermometer drops, in the presence of extension spring tractive force, thermometer body moment is retracted protection
In set, it is set to be difficult to be broken into pieces in the presence of protective case；
Be engaged by chute with sliding block one so that thermometer body during passage or measurement more stablize and
It is difficult to swing；
The antiskid groove that is set by protective case surface and and protective case and thermometer body between the spongy layer that sets
Or make the protecting effect that enhances protective case.
