Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a depth gauge with a dial used for measuring a differential housing of an automobile. Background Art

[0002] The depth gauge with dial of the automobile differential housing is a special measuring tool used to measure the depth inside the differential housing to ensure that its size meets the requirements. At present, in mechanical production technology, when measuring the depth of holes in parts and equipment, a depth gauge is usually used for measurement. A probe is arranged inside the gauge. After the side head is aligned with the hole, the depth gauge is pressed down. At this time, the side head will be retracted into the depth gauge after touching the bottom of the hole, and then the hole depth data is obtained by reading the dial. If this type of measuring equipment is damaged during use, the maintenance cost is high. When using such equipment to measure the hole depth, it is possible to measure multiple hole depths at the same time. After measuring with the depth gauge, when detecting the next hole depth, the hole depth reading may be forgotten or the reading memory may be confused due to measuring multiple hole depths, making the hole depth measurement data inaccurate. Therefore, it is necessary to design a depth gauge with dial for measuring automobile differential housing. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the utility model, the main body is placed at the aperture to be measured through the arrangement of the main body, the through hole, the card plate, the measuring probe, the erasable board and the storage slot. When the measuring probe slides down and the fixed head touches the bottom of the hole, the reading can be made according to the scale line on the outer surface of the measuring probe.

The measuring probe 4 slides down and when the fixed head 5 touches the bottom of the hole, the reading can be made according to the scale lines on the outer surface of the measuring probe 4. The reading is the hole diameter depth. After measuring the hole depth, the marker pen set in the storage slot 7 can be taken out and written on the erasable board 6 to prevent the situation of forgetting the reading when measuring the next hole.

[0025] During specific use, the arrangement of the groove 9 can facilitate users to take and place the body 1.

[0026] In this embodiment, a pressure head 10 is fixedly connected to the top end of the measuring probe 4 .

[0027] During specific use, the measuring probe 4 can be moved downward by pressing the pressure head 10, and the fixing head 5 can be inserted into the hole for measurement.

[0028] In this embodiment, a slide groove 11 is provided on the front side of the body 1 , and a slider 12 is slidably connected to the outer surface of the measuring probe 4 . The slider 12 is slidably connected to the measuring probe 4 .

[0029] During specific use, the slider 12 can move up and down on the measuring probe 4 , and the slider 12 slides with the slide groove 11 .

[0030] In this embodiment, the slider 12 is slidably connected to the slide groove 11 , a cavity is provided on one side of the outer surface of the slider 12 , a limit screw 13 is threadedly connected to the inner wall of the cavity, and a rotating wheel 14 is fixedly connected to one end of the limit screw 13 .
