The utility model reaches goal of the invention by following technical solution:
A kind of tube wall thickness measuring instrument, comprise cross tube, sheer pole, holder, clock gauge and contact, its structure is: cross tube and sheer pole are fixed on a side of holder parallel to each other, one end of cross tube is fixed a clock gauge, one end of sheer pole is fixed a contact, and the movable gauge rod of clock gauge passes cross tube and contact is aimed at.
A kind of tube wall thickness measuring instrument comprises support, clock gauge and contact, and its structure is: support is " Contraband " type, top rail and bottom rail are parallel to each other, one end of top rail is clock gauge fixedly, and an end of bottom rail is fixed a contact, and the movable gauge rod of clock gauge passes top rail and contact is aimed at.
Described tube wall thickness measuring instrument, its structure is: cross tube and sheer pole all are expansion links.
Described tube wall thickness measuring instrument, its structure is: holder is hollow or solid, its profile is rectangular parallelepiped, oval cylinder or spheroid,
Described tube wall thickness measuring instrument, its structure is: holder is a side of cross tube and sheer pole fixedly, has 2 to 4 grooves between cross tube and sheer pole, and depth of groove is between 0.5cm to 5cm.
Described tube wall thickness measuring instrument, its structure is: connect the connecting link of top rail and bottom rail in " Contraband " type support, have 2 to 4 grooves in this side of junction between top rail and bottom rail, depth of groove is between 0.5cm to 5cm.
Described tube wall thickness measuring instrument, its structure is: clock gauge is pointer display type or digital display type, when the movable gauge rod of clock gauge and contact rigidly connect when touching, the reading of clock gauge is zero.
When the utility model uses, the movable gauge rod of pull-up clock gauge, make sheer pole (or bottom rail) stretch in the through hole of tubing to be measured together with contact, cross tube (or top rail) and clock gauge and movable gauge rod are in the tubing outside, unclamp movable gauge rod, make movable gauge rod and contact prop up the outer wall and the inwall of tube wall respectively, then the reading of clock gauge demonstrates the pipe thickness of tubing.For conveniently depositing, cross tube and sheer pole can also adopt expansion link, expansion link can be packed up when not using, and have reduced to deposit volume, and can further enlarge the scope of getting point measurement vertically.Use for convenient, holder can also adopt spheroid, or has groove in holder one side, and finger can embed in the groove during use, and is more convenient when hand-held.
The beneficial effects of the utility model are: simple in structure, easy to use, can go deep into tubing inside, therefore can axially get point measurement along tubing, obtain the pipe thickness of different parts, grasp the wall thickness situation of tubing more all sidedly, thereby judge the weight bearing power of tubing more exactly.
