Detailed Description
The utility model is described in further detail below with reference to the figures and specific embodiments.
As shown in fig. 1 and 2, a instrument for measuring pipeline pipe diameter, including scale 1, 1 downside of scale is fixed and is equipped with locating plate 2, 2 below of locating plate be equipped with 1 surperficial sliding fit's of scale movable plate 3, 3 fixed nuts 4 that are equipped with in one side of movable plate, nut 4 and 5 screw-thread fit of screw rod, 5 tops of screw rod and rotation handle 6 fixed connection, 3 upper surfaces of movable plate still through guide bar 7 with refer to board 8 fixed surface connection, refer to board 8 and 1 surperficial sliding fit of scale, refer to board 8 top and be equipped with the benchmark board 13 with 1 fixed surface connection of scale, benchmark board 13 and refer to the interval between board 8 and equal the interval between locating plate 2 and the movable plate 3.
Preferably, the upper end and the lower end of the screw rod 5 are both limited in the inner ring of the bearing 9, and the outer ring of the bearing 9 is fixed on the surface of the scale 1. After the design, the screw rod 5 can stably rotate, and the bearing 9 plays an axial limiting role for the screw rod.
Preferably, a plurality of telescopic mechanisms 10 are further hinged on the upper side of the scale 1. Can adjust the vertical degree of scale 1 through telescopic machanism 10 for scale 1 can keep vertical state, is equipped with three telescopic machanism 10 in this embodiment, makes scale 1 can locate in inspection shaft 15 with vertical state.
Preferably, telescopic machanism 10 includes telescopic link 10.1, telescopic link 10.1 top is connected with 1 upside of scale is articulated, telescopic link 10.1 downside and sleeve 10.2 sliding fit, offer the screw that is used for wearing to establish top holding screw 10.3 on the sleeve 10.2. The telescopic rod 10.1 can extend or contract in the sleeve 10.2, so that the length of the telescopic mechanism 10 can be changed, and the depth of the telescopic rod 10.1 in the sleeve 10.2 can be fixed by screwing the screw 10.3 on the sleeve 10.2, namely the length of the whole telescopic mechanism 10 is fixed; in this embodiment, the length of one of the telescopic mechanisms 10 can be adjusted at will, and then the vertical degree of the scale 1 can be adjusted, and the sleeve 10.2 at the bottom of the telescopic mechanism 10 is in contact with the bottom surface around the inspection well 15, so that the scale 1 is stably arranged in the inspection well 15.
