Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

Fig. 1 is a schematic structural diagram of a U-shaped measuring device, fig. 2 is a side sectional view of a U-shaped measuring device, as shown in fig. 1-2, showing a U-shaped measuring device of a preferred embodiment, including: u type measuring subject 1, U type measuring subject 1's both ends all are equipped with chi frame 2, be equipped with the survey anvil on one of them chi frame 2, be equipped with measuring component 3 on another chi frame 2, measuring component 3 includes micrometer screw rod 31, locking device 32, fixed sleeve 33 and micro-cylinder 34, micrometer screw rod 31 movable mounting is on chi frame 2, locking device 32 is installed on chi frame 2, be used for locking micrometer screw rod 31, fixed sleeve 33 is fixed on chi frame 2, and be located micrometer screw rod 31 and deviate from the one end of survey anvil, micro-cylinder 34 is coaxial to be located fixed sleeve 33 and deviates from one side of chi frame 2, the opposite side of micro-cylinder 34 is equipped with measuring force device 35.

Furthermore, as a preferred embodiment, the U-shaped measuring body 1 is provided with a plurality of weight-removing holes 11, so that the weight of the U-shaped measuring body 1 is reduced, and the production cost is reduced.

Further, as a preferred embodiment, a plurality of weight-removing holes 11 are distributed at equal intervals along the axis of the U-shaped measuring body 1.

Furthermore, as a preferred embodiment, chamfers 12 are arranged at two openings of the weight-removing hole 11, so as to prevent the hand from being punctured by sharp points at the openings.
