Abstract
The utility model discloses a pulley weight for a Pi tape, comprising a shell and a handle being arranged at one end of the shell, which is characterized in that a spring is position at the internal of the shell, and the handle is movably connected with the shell by the spring; one end of the shell is fixed with the Pi tape fixed joint device; a pointer is arranged on the link rod of the handle, the surface of shell being opposite with printer is provided with a slit and pull scale. The pulley weight and the Pi tape are connected into a whole; when in use, the operator measures the diameter with a given pull, which improves the measuring accuracy and reduces the discrepancy.
Description
Technical field
The utility model relates to a kind of chest expander, is specifically related to a kind of ∏ chi chest expander of measuring workpieces diameter.
Background technology
The diameter of general measure workpiece is the size that the girth of employing ruler elder generation measuring workpieces utilizes formula perimeter L=2 ∏ R conversion diameters again, so-called ∏ chi is exactly the ruler that directly marks the diameter scale on steel ruler, in the prior art, the using method of ∏ chi is ruler direct reading on the workpiece by staff, this operation has a drawback, promptly each measuring pulling force size may be different in measuring process, causes the measurement diameter error bigger.
The utility model content
Technical problem to be solved in the utility model is how a kind of ∏ chi chest expander is provided, and this chest expander can be connected as a single entity with existing ∏ chi, can make the tension measurement diameter of operator to set in operation, can improve measuring accuracy, reduces error.
The technical matters that the utility model proposed is to solve like this: construct a kind of ∏ chi chest expander, comprise housing and the handle that is arranged on housing one end, it is characterized in that:
Be provided with spring in A, the described housing, described handle and housing flexibly connect by spring;
The other end of B, described housing is provided with the fixedly connected mechanism of ∏ chi;
The connecting link of C, described handle is provided with pointer, and the surface that described housing is corresponding with pointer is provided with slit and pulling force scale.
According to ∏ chi chest expander provided by the utility model, it is characterized in that, the fixedly connected mechanism of described ∏ chi is trapezoidal brace, and this brace end is provided with the line of rabbet joint, screw hole and screw, and the fixed orifice that described screw can pass the ∏ ruler end part is connected to it in described line of rabbet joint.
According to ∏ chi chest expander provided by the utility model, it is characterized in that the fixedly connected mechanism of described ∏ chi comprises screw, screw hole, be arranged on the elongated end of housing front portion and be arranged on the line of rabbet joint of this elongated end end.The ∏ chi can pass the block body of this line of rabbet joint by its end and be connected in the line of rabbet joint.
According to ∏ chi chest expander provided by the utility model, it is characterized in that described spring one end can be arranged on the interior hook of housing, the other end is connected with connecting link; The part of described connecting link places in the housing.
∏ chi chest expander provided by the utility model in use, can be connected to the ∏ ruler end part on the chest expander by fixedly connected mechanism, again the ∏ chi around by on the side workpiece, by chest expander control pulling force size, just can reduce measuring error, reach higher diameter (average) measurement requirement.
Description of drawings
Fig. 1 is the structural representation of ∏ chi chest expander provided by the utility model;
Fig. 2 is the side structure synoptic diagram of the chi of ∏ shown in Fig. 1 chest expander.
Wherein, 1, trapezoidal brace, 2, housing, 3, scale, 4, handle, 5, screw and screw, 6, the housing screw hole, 7, connecting link, 8, spring, 9, pointer.
Embodiment
Below in conjunction with accompanying drawing ∏ chi chest expander provided by the utility model is elaborated.
As shown in Figure 1 and Figure 2, comprise housing 2 and the handle 4 that is arranged on housing 2 one ends, be provided with spring 8 in the housing 2, handle 4 flexibly connects by spring 8 with housing 2, and the other end of housing 2 has been provided with the fixedly connected mechanism of ∏ chi, and the connecting link 7 of handle 4 is provided with pointer 9, housing 2 and pointer 9 corresponding surfaces are provided with slit and pulling force scale 3, spring 8 one ends can be arranged on the hook in the housing 2, and the other end is connected with described connecting link 7, and the part of connecting link 7 places in the housing 2.
Wherein the fixedly connected mechanism of ∏ chi can realize by dual mode: a kind of is that front end at housing 2 is provided with trapezoidal brace 1, the end of brace 1 is provided with the line of rabbet joint 10, screw hole and screw 5, and the fixed orifice that screw 5 can pass the ∏ ruler end part is connected to it in described line of rabbet joint 10; Another kind is to comprise screw, screw hole, be arranged on the extension end of shell end and be arranged on the line of rabbet joint of elongated end, and the ∏ chi can pass the block body of this line of rabbet joint by its end and be connected in the line of rabbet joint.
