Embodiment
Please refer to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of device for detecting length, comprising: housing 101, and described housing 101 bottoms are provided with roller 102, described roller 102 is coaxially connected with the first gear 103, and the diameter of described the first gear 103 is less than the diameter of described roller 102; Counter 104, on the transmission shaft 105 of described counter 104, be arranged with the second gear 106, described the first gear 103 can drive described the second gear 106 to rotate, and to change the reading of described counter 104, the reading of described counter 104 is for measuring the rolling distance of described roller 102.
In the present embodiment, rolling by roller 102 on object under test, drive the first gear 103 to rotate, and then drive the second gear 106 to rotate, thereby the transmission shaft of actuation counter 104 105 rotates, make counter 104 start counting, the reading of counter 104 is the rolling distance of described roller 102, just can measure thus the length of object under test, because length detection dress volume is small and exquisite and be not subject to object under test length restriction, therefore can measure easily longer object under test, can also to thering is the surface profile of the object of concave-convex curved surface, measure easily simultaneously, reduced thus measurement difficulty and improved measurement accuracy.
In the present embodiment, preferably, the transmission shaft 105 of described counter 104 is along the radial level setting of described roller 102, make thus counter 104 also along the radial level setting of roller 102, can effectively reduce the thickness of device for detecting length, make device for detecting length structure more compact and facilitate reading, simultaneously, can utilize the radical length of roller 102 to make counter 104 there is the reading compared with long number, and then make the device for detecting length can the longer length of disposable measurement.Certainly, the transmission shaft 105 of counter 104 also can be along the radially vertical or oblique setting of roller 102, also can be along the axial setting of roller 102, and the utility model is not specifically limited this.
In the present embodiment, preferred, the first gear 103 and the second gear 106 are conical gear and intermeshing.Make thus the transmission shaft 105 of described counter 104 along the radial level setting of described roller 102, make counter 104 also along the radial level setting of roller 102 simultaneously, therefore can effectively reduce the thickness of device for detecting length, make device for detecting length structure more compact and facilitate reading.Also can utilize the radical length of roller 102 and counter 104 is highly set, making several devices 104 not exceed the scope of radical length and the height of roller 102, making device for detecting length structure more compact.Certainly, between the first gear 103 and the second gear 106, also can along the radial level of described roller 102, arrange by transmission shaft 105 that transmission gear realizes counter 104 is set, the utility model is not specifically limited this.
In the present embodiment, preferred, device for detecting length also comprises that the 3rd gear 107 and the 4th gear 108, the three gears 107 are spur gear, and the 4th gear 108 is conical gear; The first gear 103 is spur gear, and the second gear 106 is conical gear, described the first gear 103 and the 3rd gear 107 engagements, and described the 3rd gear 107 is coaxially connected with the 4th gear 108, described the 4th gear 108 and described the second gear 106 engagements.Make thus the transmission shaft 105 of described counter 104 along the radial level setting of described roller 102, make counter 104 also along the radial level setting of roller 102 simultaneously, therefore can effectively reduce the thickness of device for detecting length, make device for detecting length structure more compact and facilitate reading.Simultaneously, the 3rd gear 107 and the 4th gear 108 can be arranged on to a side of housing 101, thereby the radical length that can more efficientlyly utilize roller 102 makes counter 104 have the more reading of long number, and then make the device for detecting length can the longer length of disposable measurement.
