Detailed Description
To facilitate an understanding of the utility model, the utility model will now be described more fully with reference to the accompanying drawings. Several embodiments of the utility model are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Referring to fig. 1 and 2, the present invention provides an inclination angle detecting device, which includes a base 1, wherein the base 1 is provided with a plurality of holes, and a fixture 2 is fixed on the base 1 through a locking member, so that fixtures of different types can be conveniently fixed and installed.
The product 6 to be tested is fixed in the clamp 2, the central axis of the product 6 to be tested is perpendicular to the base 1 when the product 6 to be tested is installed, and the product 6 to be tested can be vertically fixed in the clamp 2 under the general condition by matching the reference surface of the product 6 to be tested with the clamp 2.
One side of anchor clamps 2 is fixed with support 3, and support 3 passes through the retaining member to be fixed on base 1, and support 3 comprises vertical support and horizontal support, is equipped with vertical spout in the vertical support, is equipped with horizontal spout in the horizontal support, and vertical support passes through the retaining member to be fixed on base 1, and the horizontal line support passes through the retaining member on vertical support.

Preferably, the light source 4 is generally arranged to be fixed perpendicular to the base 1, so as to ensure that the light emitted from the light source 4 is parallel to the central axis of the product 6 to be measured. The device can be conveniently debugged before the inclination angle detection device is used. The light source 4 may be fixed at any angle to the base 1, but the adjustment workload is increased by fixing at any angle compared with the vertical fixing.
