Fig. 1 is a schematic block diagram of a measuring device for a hinge axis according to an embodiment of the present invention, which provides a measuring device for a hinge axis, as shown in fig. 1 and referring to fig. 2 to 8. The hinge shafts 110 are two, and each hinge shaft 110 is vertically installed to the base 120 with one hinge shaft 110 being positioned above the other hinge shaft 110. The measuring device 200 includes an indicator plate 210 and two measuring portions. The indicating plate 210 is horizontally disposed between the two hinge shafts 110. Each of the measuring portions is configured to extend an axis of one of the hinge shafts 110 to intersect the indicating plate 210 so that the positions of two hinge shafts 110 are indicated on the indicating plate 210.

In the measuring device for the hinge shafts provided by the embodiment of the utility model, the two measuring parts respectively extend the axes of the two corresponding hinge shafts 110 to intersect with the indicating plate 210, and the coaxiality of the two hinge shafts 110 is measured through the two positions of the two hinge shafts 110 indicated on the indicating plate 210, so that the operation is convenient and the measurement is accurate.

In some embodiments of the present invention, the indication plate 210 is a transparent plate, and the upper surface and/or the lower surface of the transparent plate has a grid scale, which may be made of plastic, that is, the indication plate 210 is a transparent plastic grid ruler. The measuring parts located above and below the transparent plate extend the axes of the corresponding hinge axes 110 and intersect the transparent plate to indicate the positions of the two hinge axes 110 on the same reference plane, thereby measuring the coaxiality of the two hinge axes 110. The transparent plate enables the hinge shafts 110 at different positions to be transferred to the same reference plane, so that measurement is facilitated, and the transparent plate is provided with grid scales, so that measurement is accurate.

In some embodiments of the present invention, as shown in fig. 7, the measuring portion is a double-headed laser transmitter 220, the double-headed laser transmitter 220 can be generally battery-powered, can emit light upwards and downwards simultaneously, and the two light beams are located on the same straight line. One light ray is used to coincide with the axis of the corresponding hinge shaft 110, and the other light ray is used to be projected on the indicating plate 210.

Specifically, when the coaxiality of the two hinge shafts 110 is measured, as shown in fig. 2, the measuring device 200 is placed flush with the base 120, the upper double-headed laser transmitter 220 is opened to emit light at both ends thereof, the position of the double-headed laser transmitter 220 is adjusted to make the light at the upper end coincide with the axis of the upper hinge shaft 110, and the light at the lower end is projected onto the indicator plate 210 to form a positioning point. Likewise, the lower double-headed laser transmitter 220 is used to measure the position of the lower hinge shaft 110 and to project the position of the axis of the lower hinge shaft 110 on the indicating plate 210 by means of the transmitted light, forming a locating point. By measuring the positions of the two beams projected on the indicator board 210, the coaxiality of the upper and lower hinge axes 110 can be measured. For example, the distance between the two positioning points is obtained by comparing the distance between the two positioning points with a grid ruler or by measuring the distance with a measuring tool such as a digital caliper. Therefore, the coaxiality of the two to be tested can be deduced, and whether the hinge installation meets the requirements or not can be judged according to the coaxiality. In the same way, the coaxiality of the upper hinge axis and the middle hinge axis, the coaxiality of the upper hinge axis and the lower hinge axis and other two objects can be measured. And the laser light emitted from the dual-headed laser transmitter 220 has the characteristics of high brightness and long propagation distance, so that the light projected on the indicator board 210 is easy to observe and is suitable for measuring the condition of the two hinge shafts 110 with long distance.

The base 120 may be a cabinet of a refrigerator-freezer.

Specifically, when measuring the distance between two hinge shafts 110 horizontally spaced, as shown in fig. 3, the measuring device 200 is placed flush with the base 120, a double-headed laser emitter 220 at one end of the traverse rod 232 is opened to emit light at both ends thereof, the position of the double-headed laser emitter 220 is adjusted to make the light at one end coincide with the axis of the hinge shaft 110, and the indicating tip 264 of the chucking device 260 provided on the double-headed laser emitter 220 indicates a scale on the traverse rod 232 to obtain a distance value.
