Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a portable retractable depth gauge. Background Art

[0002] A depth gauge is a measuring tool that is mainly used to measure the depth of an object. It is similar to a vernier caliper, but has a T-shaped structure. Depth gauges usually have high accuracy and response speed, and their resolution can reach 0.01mm, with an error control within 0.03mm. When using a depth gauge, it is necessary to place the measuring base on a platform, such as a marble platform, and then move the scale frame to make the end face of the measuring needle flush with the measuring base. There are two types of depth gauges: digital depth gauges and vernier depth gauges. Digital depth gauges display the depth value on a liquid crystal display, while vernier depth gauges require the depth to be read by observing the alignment of the scale lines between the vernier and the ruler body. During use, it is necessary to keep the depth gauge clean and maintained to extend its service life.

[0003] The existing depth gauge is relatively long. When using the depth gauge, the user needs to place the depth gauge separately in a storage space, which requires a relatively long storage space or a storage box, is less convenient, and also consumes a large amount of space during transportation and stacking. Multiple vehicles are required for batch transportation multiple times, which increases transportation costs and consumes more transportation time. Utility Model Content

[0004] The purpose of the utility model is to provide a portable retractable depth gauge to solve the problems raised in the above background technology.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the utility model, a stacking mechanism is provided. The stacking mechanism achieves a stacking effect by stacking multiple sets of second ruler bodies on the first ruler body. When not in use, the second ruler bodies can be stored, thereby realizing compact storage of the ruler. During transportation, the space occupied by the stacked rulers is greatly reduced, which is beneficial to reducing transportation costs and improving transportation efficiency. The stacking mechanism adopts a threaded connection method, so that the second ruler body can be easily stacked and disassembled with the first ruler body, thereby improving the flexibility of the depth gauge and allowing the ruler length to be quickly adjusted according to actual needs. The stacking mechanism allows the user to adjust the ruler length according to actual needs, making it suitable for measuring objects of different sizes and shapes, thereby improving the applicable scope of the depth gauge and meeting diverse measurement needs.

[0016] 2. In the utility model, a telescopic mechanism is provided, and the telescopic mechanism controls the telescopic operation of multiple groups of fourth ruler bodies by connecting screw bodies, thereby realizing flexible adjustment of ruler length. Users can freely choose a suitable ruler length according to measurement requirements, thereby improving the adaptability and practicality of the depth gauge. The multiple groups of fourth ruler bodies in the telescopic mechanism are thin and can be stored in the second vernier ruler, thereby reducing the volume of the telescopic mechanism, making the depth gauge more convenient to carry. Users can put the retracted ruler into a pocket or tool bag for easy carrying and use. The depth gauge usually needs to adapt to the measurement of objects of different sizes and shapes. The existence of the telescopic mechanism enables the depth gauge to have a wider measurement range. Users can meet different measurement requirements by adjusting the ruler length, thereby improving the applicability and flexibility of the depth gauge. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The working principle of the utility model is as follows: the depth gauge is additionally provided with a stacking mechanism 2 and a telescopic mechanism 3. The stacking mechanism 2 adopts a stacking structure. By means of a first threaded seat 203, a second threaded seat 204 and a docking screw 205, a plurality of second ruler bodies 202 are stacked on a first ruler body 201. During transportation, the second ruler bodies 202 in the stacking mechanism 2 can be stored in a placement slot 4. The telescopic mechanism 3 also adopts a stacking structure.

Then, the second ruler bodies 202 are stacked on the first ruler body 201 with the help of the first threaded seat 203, the second threaded seat 204 and the docking screw 205 to achieve a stable stacking effect, and the first vernier ruler 206 and the first measuring claw 207 are slid upward, so that the first measuring claw 207 is placed on the upper surface of the part to be measured. The third scale body 301 is rotated to the top of the base 1, so as to be at a 90-degree angle with the horizontal plane of the base 1, and then the second limiting screw sleeve 308 is rotated, and the second limiting screw sleeve 308 is used to squeeze the second clamping ring 306 to stabilize the position of the third scale body 301. Then, the fourth scale body 302 is installed on the third scale body 301 with the help of the connecting screw body 303, and then the second vernier scale 304 and the second measuring claw 305 are slid up, so that the second measuring claw 305 is placed on the upper surface of the part to be measured, so as to obtain the scale information.
