Embodiment 1

[0024] Such as figure 1 , 2 , 3, the carbon fiber vernier caliper comprises a main ruler 1, a vernier ruler 2 and a sounding ruler 3, and the main ruler 1, the vernier ruler 2 and the sounding ruler 3 are all made of carbon fiber materials. The vernier ruler 2 is set on the main ruler 1 and can slide along the main ruler 1. The back of the main ruler 1 is provided with a square chute 4 for embedding the sounding ruler 3, and the vernier caliper is detachably connected with the sounding ruler 3.

[0025] The main ruler 1 has a storage cavity 5, the opening of the storage cavity 5 is located at the tail end of the main ruler 1, the sounding ruler 3 can be inserted into the storage cavity 5, the depth of the storage cavity 5 is greater than the length of the sounding ruler 3, and the storage Cavity 5 is rectangular parallelepiped, is threaded with the bolt 6 that seals off storage chamber 5 openings on main chi 1 tail end.

[0026] The front end of the sounding gauge 3 has a co...

Embodiment 2

[0028] Such as Figure 4 , Figure 5 As shown, the difference from Embodiment 1 is that the connection mode between the sounding scale 3 and the vernier scale 2 is different. The front end of the sounding ruler 3 in this embodiment has an upwardly protruding block 9, and the end surface of the vernier 2 is connected with a bar-shaped auxiliary block 10 through a screw 11, and the inner side of the bar-shaped auxiliary block 10 is provided with a hole for the locking block 9 to snap into. Square notch 12. During dismounting, the screw 11 is unscrewed, the bar-shaped auxiliary block 10 is opened, the block 9 of the sounding gauge 3 can be disengaged from the square notch 12, and then the sounding gauge 3 is inserted in the storage cavity 5 .

Abstract

The invention provides a carbon fiber vernier caliper, comprising a main ruler, a vernier ruler and a depth ruler. The vernier ruler sleeves the main ruler and can slide along the main ruler. The backof the main ruler is provided with a square chute for embedding the depth ruler. The vernier caliper is detachably connected with the depth ruler. The main ruler has a storage cavity. The opening ofthe storage cavity is located at the tail end of the main ruler. The depth ruler can be inserted into the storage cavity. The tail end of the main ruler is in threaded connection with a bolt for sealing the opening of the storage cavity. The main ruler, the vernier ruler and the depth ruler are made of carbon fiber materials. The main ruler, the vernier ruler and the depth ruler are made of carbonfiber material such that the weight of the entire carbon fiber vernier caliper is much smaller than that of the stainless steel vernier caliper, and is greatly improved in corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping tools, and relates to a carbon fiber vernier caliper. Background technique [0002] The vernier calipers widely used at present are all made of stainless steel, which require high precision, are made by special technology, are expensive, and are not suitable for use in corrosive environments. Carbon fiber is a new type of fiber material with high strength and high modulus with a carbon content of more than 95%. It is formed by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber. And the obtained microcrystalline graphite material. Carbon fiber is "soft on the outside and rigid on the inside". It is lighter than metal aluminum, but its strength is higher than that of steel, and it has the characteristics of corrosion resistance and high modulus. It is an important material in national defense and civilian applications. It not only has ...
