Description
Technical Field
The utility model relates to a measuring instrument field especially relates to an external micrometer.
Background
Outside micrometer, also called micrometer screw, is often referred to as "micrometer" for short. The micrometer is a length measuring instrument which is more precise than a vernier caliper, the precision is several types of 0.01mm, 0.02mm and 0.05mm, and the 3 rd bit (thousands of bits) after decimal point can be read by adding 1 bit of estimated reading, so the micrometer is called. The required measuring accuracy who requires of micrometer is very high, measure through anvil and micrometer screw rod, but take out back anvil and micrometer screw rod by the box body with the micrometer and expose outside usually, do not need to place it in the box body again for the convenience when measuring like this, otherwise frequently take and can make comparatively loaded down with trivial details, but directly place it on the desktop when waiting to measure and take place to bump easily, especially the terminal surface department of anvil and micrometer screw rod takes place to collide with easily to cause the measuring inaccuracy.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide an external micrometer.
The utility model discloses a realize through following technical scheme: the utility model provides an external micrometer, includes the chi frame and fixes anvil cell and the micrometer screw rod on the chi frame, be equipped with the guard bar between anvil cell and the micrometer screw rod, the one end that the guard bar is close to the anvil cell is fixed with the elasticity and hangs the rope, the elasticity is hung the rope and is cramped on the chi frame, the guard groove has been seted up respectively at the both ends of guard bar, the diameter of guard groove slightly is greater than the diameter of anvil cell and micrometer screw rod, the draw-in groove has been seted up on the chi frame, it has the rubber pad to adhere on the inner wall of guard groove.
The utility model has the advantages that: when the micrometer is temporarily placed, the end faces of the measuring anvil and the micrometer screw and the side faces close to the end faces are not collided, the measurement stability is ensured, and the end faces of the measuring anvil and the micrometer screw can be prevented from being scratched through a rubber pad; hang the rope through elasticity then can make elasticity hang the rope and take place deformation to hoop tightly on the chi frame through external force, conveniently remove the fender rod like this, can make elasticity hang the rope and move to the below of chi frame and make the fender rod remove like this when needs use like this, can not influence the measurement like this to can hang the rope with elasticity and hoop tightly in the draw-in groove, can prevent like this that elasticity from hanging the rope because frictional force diminishes and the landing.
Drawings
Fig. 1 is a schematic front view of the present invention;
fig. 2 is a schematic top view of the present invention;
in the figure: 1. a ruler frame; 2. measuring an anvil; 3. a micrometer screw; 4. a guard bar; 5. an elastic hanging rope; 6. a protective bath; 7. a clamping groove.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model discloses a ruler frame 1 and fix survey anvil 2 and the micrometer screw rod 3 on ruler frame 1, be equipped with protective rod 4 between survey anvil 2 and the micrometer screw rod 3, protective rod 4 is close to the one end of survey anvil 2 and is fixed with elasticity and hangs rope 5, elasticity is hung rope 5 and is cramped on ruler frame 1, protective tank 6 has been seted up respectively at protective rod 4's both ends, protective tank 6's diameter slightly is greater than the diameter of survey anvil 2 and micrometer screw rod 3, draw-in groove 7 has been seted up on ruler frame 1, it has the rubber pad to adhere on protective tank 6's the inner wall.
The utility model has the advantages that: when the measurement is not needed, firstly, the elastic hanging rope 5 is pulled to enable the protective rod 4 fixed on the elastic hanging rope 5 to be close to the measuring anvil 2 and the micrometer screw 3, at the moment, the protective rod 4 is rotated to enable the protective groove 6 close to the measuring anvil 2 to be inserted into the measuring anvil 2, and the micrometer screw 3 is rotated forwards by screwing the knob to be inserted into the protective groove 6 on the other side of the protective rod 4, so that the end faces and the side faces close to the end faces of the measuring anvil 2 and the micrometer screw 3 are not collided when the micrometer is temporarily placed, the measurement stability is ensured, and the end faces of the measuring anvil 2 and the micrometer screw 3 can be prevented from being scratched through rubber pads; hang rope 5 through elasticity then can make elasticity hang rope 5 and take place deformation to hoop tightly on chi frame 1 through external force, conveniently remove fender rod 4 like this, can make elasticity hang rope 5 and make fender rod 4 remove to the below removal of chi frame 1 like this when needs use, can not influence the measurement like this to can hang rope 5 with elasticity and hoop tightly in draw-in groove 7, can prevent like this that elasticity from hanging rope 5 because frictional force diminishes and the landing.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
