Abstract
The utility model discloses a measuring tool for wall thickness and external diameter of a steel pipe, which comprises a bracket and a dial indicator, wherein the dial indicator adopts a pointer to realize displaying; the bracket made of metal comprises an upper cross rod, a lower cross rod and a connecting rod; one ends of the upper cross rod and the lower cross rod are connected with the connecting rod; the dial indicator is fixed at the other end of the upper cross rod and is located at one side of the upper cross rod far away from the lower cross rod; a movable rod of the dial indicator passes through the upper cross rod; a contact is arranged at one side of the other end of the lower cross rod close to the upper cross rod; the movable rod is aligned with the contact; a scale layer is arranged at the lower edge of the lower cross rod along the length direction; and both the upper cross rod and the lower cross rod are telescopic.
Description
Technical field
The utility model relates to a kind of survey instrument, relates in particular to a kind of diameter of steel tube and wall thickness measuring device.
Background technology
The wall thickness of steel pipe has material impact to the mechanical property of tubing, the measurement of thickness of steel pipe at present is mainly by vernier caliper, but vernier caliper has a shortcoming to be exactly, it can only measure the thickness of the tube wall of the mouth of pipe, be difficult to the thickness of the tube wall in the measuring tube, this has just limited the wall thickness situation of understanding tubing on the whole, can't find the situation that wall unevenness is even, the external diameter of measuring steel pipe now also needs to look in addition instrument, uses inconvenience.
The utility model content
The purpose of this utility model just is to provide the survey instrument of a kind of thickness of steel pipe and external diameter, not only can measure the pipe thickness of steel duct easily, can also be used for measuring external diameter.
In order to solve the problems of the technologies described above, the technical solution of the utility model is such: the survey instrument of a kind of thickness of steel pipe and external diameter, comprise support, the clock gauge that pointer shows, described support is a metal support, comprise cross tube, sheer pole and connecting link, one end of described cross tube and sheer pole is connected connecting link, the other end of described cross tube is clock gauge fixedly, described clock gauge is positioned at the side of cross tube away from sheer pole, the motion bar of described clock gauge passes cross tube, the other end of described sheer pole is provided with a contact near a side of cross tube, described motion bar and contact are aimed at, the lower limb of described sheer pole prolongs its length direction and is carved with the scale layer, and described cross tube and sheer pole are expansion link.
Compared with prior art, advantage of the present utility model is: simple in structure, upper and lower cross bar is expansion link, during use, sheer pole can stretch in the pipe, and the thickness of the tube wall of diverse location in the measuring tube is more comprehensively grasped the wall thickness situation of tubing, on sheer pole, engrave the scale layer, can measure external diameter.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
By shown in Figure 1, the utility model is by support, the clock gauge 4 that pointer shows is formed, described support is a metal support, comprise cross tube 1, sheer pole 2 and connecting link 3, one end of described cross tube 1 and sheer pole 2 is connected connecting link 3, the other end of described cross tube 1 is clock gauge 4 fixedly, described clock gauge 4 is positioned at the side of cross tube 1 away from sheer pole 2, the motion bar 5 of described clock gauge 4 passes cross tube 1, the other end of described sheer pole 2 is provided with a contact 6 near a side of cross tube 1, described motion bar 5 and contact 6 are aimed at, and the lower limb of described sheer pole 2 prolongs its length direction and is carved with scale layer 7, and described cross tube 1 and sheer pole 2 are expansion link.
Simple in structure, cross tube 1 and sheer pole 2 are expansion link, and during use, sheer pole 2 can stretch in the pipe, and the thickness of the tube wall of diverse location in the measuring tube is more comprehensively grasped the wall thickness situation of tubing, engraves scale layer 7 on sheer pole 2, can measure external diameter.
