Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and more specifically, to a double-hook depth gauge. Background Technology

[0002] The double-hook depth gauge is a precision measuring tool used to measure the depth of holes, grooves, steps, etc. It is characterized by having two symmetrical hook-shaped probes and is suitable for depth measurement in confined spaces or special structures.

[0003] Existing double-hook depth gauges are complex in structure, made of hard materials, and are difficult and cumbersome to manufacture. The double-hook design requires ensuring symmetry and consistency, making it prone to deformation during machining. High-precision dimensions and surface roughness requirements pose challenges to machine tools and cutting tools. The hardened material after heat treatment increases the cutting difficulty, and multi-process machining (such as milling, grinding, and heat treatment) requires strict control to avoid cumulative errors. Furthermore, stress concentration is prone to occur in the fine structures of the hook head area, further increasing the complexity of process control. High-precision equipment and skilled technicians are needed to ensure product quality, resulting in high production costs. Summary of the Invention

[0004] This utility model aims to at least partially solve one of the aforementioned technical problems in the prior art. Therefore, one objective of this utility model is to provide a double-hook depth gauge that is structurally stable, simple in manufacturing process, highly accurate in measurement, introduces minimal error, and has lower production costs.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A double-hook depth gauge includes a frame 1 and a body 2. One end of the frame 1 is provided with a base surface 102. A sliding groove 101 is provided along the length of the frame 1. The body 2, which can move along the sliding groove 101, is provided in the sliding groove 101. The body 2 extends out of both ends of the frame 1 and is perpendicular to the base surface 102. The two sides of the lower end of the body 1 are provided with an outer hook 3 and an inner hook 4.

[0007] The beneficial effects of this invention are: the measuring end of the ruler has two hooks for measurement, which can contact the upper and lower edges of the object being measured, improving measurement stability and accuracy, and is especially suitable for measuring deep holes or grooves. The connection structure and manufacturing process of the hooks on both sides have been optimized and improved based on the original depth ruler structure, ensuring structural stability while reducing the production difficulty and cost of the double-hook depth ruler.

[0008] Based on the above technical solution, the present invention can be further improved as follows:

[0009] The outer hook 3 and the inner hook 4 are perpendicular to the ruler body 2, and the outer hook 3 and the inner hook 4 are fixedly connected to the ruler body 2 through a round hole provided at the lower end of the ruler body 2.

[0010] The advantages of adopting the above-mentioned further solution are: the outer hook and the inner hook are embedded in the round hole at the lower end of the ruler body, the structure is simple, the round hole is easier to produce and the size is easier to control, and the process requirements and production costs are reduced.

[0011] Furthermore, the outer hook head 3 and the inner hook head 4 are cylindrical measuring heads.

[0012] The advantages of adopting the above-mentioned further solutions are: the cylindrical measuring head is easier to manufacture and control in terms of size, can be made into a universal standard part, the assembly process is simpler, and production costs can be effectively reduced.

[0013] Furthermore, the outer hook head 3 and the inner hook head 4 are tangent to each other and are located on both sides of the ruler body 2, and the cylindrical surface of the inner hook head 4 protrudes from the lower end face of the ruler body 2.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the inner and outer hooks are tangent to ensure that the gap between them is zero, and the data measurement is accurate when the inner and outer hooks are measured at the same time.

[0015] Furthermore, a fixed grid 6 is fixedly installed on the end face of the ruler body 2, and a digital display component 5 is installed on the upper end of the ruler frame 1 by fastening screws. The input end of the digital display component 5 is located at the upper end of the fixed grid 6 and moves with the ruler frame 1 at the upper end of the fixed grid 6.

[0016] The advantages of adopting the above-mentioned further solution are: by utilizing the relative displacement between the digital display component and the fixed grid movement, the depth data measured by the hook head can be quickly obtained, which is convenient to operate, accurate in measurement, and effectively improves the detection efficiency.
