Description

  The present invention relates to a measuring instrument cover and a measuring instrument.

Conventionally, a digital display caliper (see Patent Document 1) is known.
This includes a main scale having one measurement jaw, and a slider having the other measurement jaw that is provided so as to be movable with respect to the main measurement scale and is brought into contact with the measurement portion of the object to be measured together with the one measurement jaw. An encoder that detects the amount of movement displacement of the slider relative to the main scale, and a digital display unit that digitally displays the amount of movement displacement.

JP-A-6-307802 (FIG. 1)

  However, when using this digital display caliper, the user may accidentally drop it or hit it against other objects, or it may be damaged, or the encoder or digital display unit may be damaged by impact. There is a problem that it interferes with the detection or reading of accurate measurement values.

  It is an object of the present invention to provide a measuring instrument cover that can prevent damage and malfunction of a measuring instrument due to an external impact by being attached to the measuring instrument, and damage and malfunction caused by an external impact. It is providing the measuring device which can prevent.

  The measuring instrument cover of the present invention includes a cover main body that is made of an elastic member and covers at least a part of the measuring instrument, and an inner surface that is in contact with the measuring instrument of the cover main body, and an opposite side of the inner surface. Concavities and convexities are formed on at least one of the outer surfaces.

The cover main body of the measuring instrument cover of the present invention covers the measuring instrument, and its inner surface is in contact with the measuring instrument.
Since the cover body is made of an elastic member, even if the user accidentally drops the instrument while the instrument cover is attached to the instrument, the impact on the instrument is not affected by the instrument. Alleviated by the cover. Therefore, it is possible to prevent damage to the measuring instrument and occurrence of problems.
Furthermore, the measuring instrument cover of the present invention is easily elastically deformed at the portion where the unevenness of the cover body is formed. Therefore, when an impact is applied from the outside, the uneven portion is elastically deformed so as to absorb the impact, and the impact applied to the measuring instrument is reduced. Therefore, damage and malfunction of the measuring instrument are less likely to occur.

  Moreover, according to this invention, since a hand does not touch a measuring device directly, it can also prevent that a malfunction arises in a measuring device with the heat of a hand. Since the cover body covers the measuring instrument, it is possible to prevent the measuring instrument from being contaminated.

  In the present invention, the measuring instrument includes a display unit for displaying a measurement value, and the cover body is provided with an opening for exposing the display unit and a thickness provided near the opening provided near the opening. A configuration including a taper portion having a shape in which the thickness becomes thinner is preferable.

  In the present invention, since the thickness of the cover main body becomes thinner as it approaches the opening due to the provision of the tapered portion, the display value of the display exposed in the opening is reduced due to the thickness of the cover main body. It won't be difficult to read.

  In the present invention, it is preferable that the unevenness formed on the inner surface of the cover body forms one or a plurality of discharge grooves, and at least one end of the discharge grooves is open.

  When a measuring instrument is used in a situation where oil, coolant, or the like is easily attached, oil or coolant may enter between the inner surface of the cover body and the surface of the measuring instrument. However, according to the present invention, the oil or the coolant can be guided by the discharge groove formed on the inner surface of the cover body and discharged outside at the open end of the discharge groove.

In particular, when the measurer performs measurement by holding the cover body with his / her hand, the oil or the coolant can be discharged more smoothly. That is, the inner surface of the cover main body is pressed against the surface of the measuring instrument by the gripping force of the hand, so that the oil or coolant that has entered between them is easily pushed out into the discharge groove formed on the inner surface of the cover main body. Furthermore, since the cover body is made of an elastic member, the discharge groove is contracted and deformed by being pressed by the gripping force of the hand, so that oil and coolant are easily pushed out from the open end of the discharge groove.

  In the present invention, it is preferable that the other end of the discharge groove is closed in the vicinity of the opening.

  According to the present invention, since the discharge groove is closed at the other end in the vicinity of the opening, oil or coolant that has entered between the inner surface of the cover body and the surface of the measuring instrument is directed from the opening toward the display. Will not be discharged. For this reason, since the display unit is not soiled by oil or coolant, the visibility is hardly hindered when reading the measurement value displayed on the display unit.

  In the present invention, the cover main body includes an outer surface layer formed on the outer surface side, and an inner surface layer formed integrally with the outer surface layer on the inner surface side, and the outer surface layer is made of a hard material. It is preferable that the surface is formed of an elastic member, the unevenness is formed on the surface, and the inner surface layer is formed of a soft elastic member.

In this invention, since the inner surface layer made of a soft elastic member comes into contact with the measuring instrument, further shock absorption can be ensured.
Since the inner surface layer is made of a soft elastic member, it can be elastically deformed to match the surface shape of the measuring instrument. Therefore, since the inner surface layer and the measuring instrument can be in close contact with each other, it is possible to prevent oil or coolant from entering between them.

  In addition, since it is difficult to maintain the shape only with the inner surface layer made of a soft elastic member, an outer surface layer made of a hard elastic member is provided, and the inner surface layer is held in a predetermined shape. For this reason, the measuring instrument cover of the present invention can be attached to and detached from the measuring instrument without impairing the above-described effects based on the inner surface layer being a soft elastic member. That is, even if the measuring instrument cover is removed from the measuring instrument, the outer cover layer is hard, so that the measuring instrument cover can retain its shape until it is attached to the measuring instrument again. For this reason, there is no inconvenience in installation due to deformation of the measuring instrument cover at the time of reattachment.

  In the present invention, it is preferable that the cover body is formed integrally with the measuring instrument so that the inner surface is in close contact with the surface of the measuring instrument, and the unevenness is formed on the outer surface.

  According to the present invention, the cover main body and the measuring instrument are integrally formed, and the inner surface of the cover main body and the surface of the measuring instrument are in close contact with each other without any gap, so that there is no possibility that oil or coolant enters between them.

  In the present invention, it is preferable that the cover main body is open on one surface side of the measuring instrument, and a surface protection portion that covers the edge of the one surface is formed on the periphery of the open portion.

  Here, as one surface of the measuring instrument whose edge is covered by the surface protection portion, the bottom surface is the most effective, but any other surface may be used. If the cover main body is open on the bottom side of the measuring instrument, the other surface of the measuring instrument will be covered with the cover main body, and the desired protection performance can be obtained, and the surface at the periphery of the open part on the bottom side The protective part can mitigate the impact on the bottom side of the measuring instrument.

  Moreover, in this invention, a measuring device provided with the measuring device main body which has an unevenness | corrugation in at least one part of the surface, and the coating film which has an elasticity apply | coated to the said unevenness | corrugation part of this measuring device main body surface can be comprised.

  According to the present invention, since the coating film has elasticity, even if the measuring instrument of the present invention is accidentally dropped, the impact on the measuring instrument body is alleviated by the coating film. Therefore, it is possible to prevent damage to the measuring instrument and occurrence of problems.

  Moreover, in this invention, since the unevenness | corrugation is formed in the surface of a measuring device main body, the coating film formed according to the surface shape of a measuring device main body also becomes uneven | corrugated shape. The unevenness on the surface of the measuring instrument is formed for the purpose of mitigating external impacts.By forming an elastic uneven film on the unevenness, the coating film is formed. It will be elastically deformed so as to absorb the impact from the outside, and the impact applied to the measuring instrument body will be further reduced.

  Moreover, according to this invention, since there is no gap between the surface of the measuring instrument main body and the coating film, there is no possibility that oil or coolant enters.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
