Fig. 1 is a schematic sectional view of a front view of a pin shaft in a non-lifted state according to the technical solution of the present invention;
fig. 2 is a three-dimensional view of the pin shaft in the raised state according to the technical solution of the present invention;
the corresponding labels in the figures are: 1-lower base, 2-control column, 3 eccentric wheel, 4-lifting shaft, 5-return spring, 6-upper base, 41-upper boss, 42-lower boss and 7-pin shaft.
Detailed Description
In order to make the technical solution of the present invention more comprehensible to those skilled in the art, the present invention is further described with reference to the accompanying drawings and examples.
Example 1:
as shown in fig. 1 and 2, the lifting eccentric wheel mechanism for the detection pin comprises a lower base 1, a control column 2, an eccentric wheel 3, a lifting shaft 4, an upper base 6, a pin shaft 7 and a return spring 5, wherein a through hole for the control column 2 to pass through is formed in the side surface of the lower base 1, a rotating hole for the control column 2 to pass through is formed in the side surface of the eccentric wheel 3, the control column 2 is fixedly connected to the eccentric wheel 3, a through hole for the lifting shaft 4 to pass through is formed in the bottom of the upper base 6, the through hole is a step-shaped through hole with a large upper part and a small lower part, an upper boss 41 and a lower boss 42 are further arranged at the bottom of the upper base 6, the upper boss 41 and the lower boss 42 are mounted on the lifting shaft 4 to form an i shape, the lower boss 42 is fixedly connected with the lifting shaft 4, the upper boss 41 is movably connected with the lifting shaft 4, the lifting shaft 4 passes through the through hole, the lower boss 42 is installed, the upper boss 41 is provided with a pin hole for the pin shaft 7 to pass through, the diameter of the return spring 5 is larger than the diameter of the small hole of the through hole and smaller than the diameters of the upper boss 41 and the lower boss 42, the diameter of the upper boss 41 is larger than the diameter of the small hole of the through hole and smaller than the diameter of the large hole of the through hole, the lower boss 42 is placed on the eccentric disc 3, and the length of the large hole of the through hole is smaller than the effective length of the eccentric disc 3 moving up and down.
Example 2:
the difference between embodiment 2 and embodiment 1 is that in embodiment 1, the lower boss 42 is fixedly connected with the lifting shaft 4, the upper boss 41 is movably connected with the lifting shaft 4, and in embodiment 2, the upper boss 41 is fixedly connected with the lifting shaft 4, and the lower boss 42 is movably connected with the lifting shaft 4.
When the lifting device is used, the lower base 1 is fixed on a mounting surface, the control column 4 penetrates through a through hole of the lower base 1 and is fixedly connected to the eccentric wheel 3 through a rotating hole, the upper base 6 is mounted on the mounting surface on the other side, the return spring 5 is sleeved on the lifting column 4, the lifting column 4 penetrates in a through hole, the pin shaft 7 penetrates in a pin hole in the upper boss 41, when the control shaft 2 is rotated, the eccentric wheel 3 starts to act, the lifting shaft 4 and the return spring 5 start to move up and down, and therefore the pin shaft 7 is driven to move up and down.
Because some hole sites needing to be detected are hidden or narrow and are not easy to detect, the detection pin lifting eccentric wheel structure is arranged, and the rotating control column can drive the eccentric wheel to rotate so as to drive the pin shaft to move up and down to detect the hole sites, so that the lower base is usually arranged in a place which is convenient to place or easy to control.
The utility model relates to a detect round pin lift eccentric wheel mechanism mainly is applicable to when needs detect the comparatively hidden or narrow and small position of hole site, with handheld like when conventional detection instrument such as smooth feeler gauge, screw thread feeler gauge, external diameter callipers gauge can't stretch into, places this mechanism below the inspection hole, reaches the detection effect in the hole of hidden or narrow and small position through the operation of spacious position in the outside.
