Description

TECHNICAL FIELD

[0001] The utility model relates to the field of measuring tools, especially a caliper for measuring a groove. BACKGROUND

[0002] In the prior art, a vernier caliper is a commonly used tool for measuring the size of the outer diameter, inner diameter, depth, etc. of an object, and is widely used in the fields of mechanical processing, manufacturing, and quality detection. However, the structure of the conventional vernier caliper has certain limitations, especially when measuring components with narrow spaces and complex geometrical shapes, it is difficult to achieve accurate measurement. Specifically, the vane of the vernier caliper is usually designed to be relatively wide and thick to ensure its stability and durability, but this design is not suitable for some special-shaped narrow spaces, such as internal grooves.

[0003] The characteristics of a narrow space are usually narrow opening, large depth, and complex and irregular internal structure. A typical example includes the internal groove of some components. The structure of the internal groove generally presents a narrow groove with fixed width and depth, and some grooves may also contain fine internal wall structures or different inclination angles. Such grooves may be used for guiding, sealing, or fixing specific components in the components, and therefore require high dimensional accuracy, which requires accurate measurement. However, the conventional vernier caliper cannot be inserted deep into the groove due to its large size, resulting in inaccurate measurement data or inability to measure.

[0004] The design of the vane of the conventional vernier caliper cannot adapt to the narrow internal groove, and it is easy to be stuck at the opening of the groove due to its large size, which cannot smoothly enter the interior, resulting in the measuring tool being unable to fully contact the internal wall of the groove. This limitation not only results in large measurement errors, but also increases the difficulty of operation, affecting the detection accuracy of precision components. SUMMARY

[0005] The utility model aims at the problem of large measurement error caused by the fact that the existing caliper cannot be inserted into the groove for accurate measurement due to its large size when measuring the groove and the hole in the groove in the prior art, and provides a caliper for measuring a groove.

[0006] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of:

[0007] A caliper for measuring a groove, comprising a main scale, the main scale being provided with a first elongated rod at one end, the first elongated rod being provided with a first measuring click at the top end; further comprising a scale frame in sliding connection with the surface of the main scale, the scale frame being provided with a second elongated rod at one end, the second elongated rod being arranged side by side with the first elongated rod, the second elongated rod being provided with a second measuring click at the top, the second measuring click cooperating with the first measuring click to realize groove measurement.

The position of second elongated rod is adjusted by sliding ruler frame, so that second measuring tooth moves along the inner wall of trench synchronously, and accurately completes measurement. Meanwhile, first measuring tooth and second measuring tooth can be contacted with the inner wall of both sides of trench respectively, to realize double-precision positioning, so as to ensure the accuracy of measurement result;The design of slidingly connected ruler frame enables calipers to be flexibly adjusted according to the width of different trenches, to adapt to the measurement demand of various sizes. When operating, the position of second measuring tooth can be adjusted by sliding ruler frame gently, without complex adjustment process, which greatly improves the convenience and efficiency of measurement.

[0009] As a preferred scheme of the utility model, the setting direction of the first measuring tooth is perpendicular to the setting direction of the first elongated rod;The setting direction of the second measuring tooth is perpendicular to the setting direction of the second elongated rod.

[0010] Such setting enables operator to correspond to the position of trench in narrow space by measuring tooth perpendicularly arranged with elongated rod after first elongated rod and second elongated rod are stretched into narrow space, to facilitate operator to quickly complete measurement.

[0011] As a preferred scheme of the utility model, the main ruler further includes a ruler body, which is arranged along the sliding direction of the ruler frame, and one end of the ruler body is connected with the first elongated rod, and a step portion is formed at the connection between the ruler body and the first elongated rod.

[0012] By arranging the step portion at the connection between the ruler body and the first elongated rod, the step structure formed thereby can provide stronger support force and torsional resistance for the entire main ruler, effectively avoiding shaking and imbalance during sliding, thereby greatly improving the stability and precision of measurement.

[0013] As a preferred scheme of the utility model, the ruler body is provided with a receiving groove, and the opening of the receiving groove faces one end of the ruler body away from the first elongated rod;A depth ruler is arranged in the receiving groove.

[0014] The receiving groove is arranged in the ruler body, and the depth ruler is arranged in the receiving groove, effectively utilizing the space of the ruler body, and the depth ruler can facilitate depth measurement for operator.

[0016] The structure synchronizes the movement of the depth ruler with the sliding action of the ruler frame through integrated design, thereby reducing the steps of operating the depth ruler alone.

[0017] The end of the ruler body away from the first elongated rod is provided with a limiting part, and the limiting part is arranged on the sliding track of the ruler frame.

[0018] The limiting part can effectively prevent the ruler frame from sliding out of the specified track range during the sliding process, thereby avoiding the ruler body from falling or being damaged due to sliding out, and improving the safety of use.

[0019] The limiting part comprises a pressing plate for preventing the depth ruler from deviating, and a baffle arranged opposite to the pressing plate and used for limiting the movement distance of the ruler frame.

[0020] The ruler frame is provided with a reading table on one side, the accommodating groove is provided with a rack arranged along the sliding direction of the ruler frame, and the rack is used for controlling the reading table to work.

[0021] The rack is arranged along the sliding direction of the ruler frame, and can drive the reading table to update the reading synchronously with the sliding position of the ruler frame.

[0022] The reading table comprises a dial plate provided with a pointer at the center, the pointer is provided with a gear at one end thereof, and the gear is engaged with the rack.

[0023] The ruler frame is provided with a limiting bolt at the top, and the setting direction of the limiting bolt is perpendicular to the setting direction of the main ruler.

[0024] The limiting bolt can be used for accurately fixing the sliding position of the ruler frame during measurement, so that the user can more conveniently set and keep the measurement position, thereby reducing the possibility of position deviation, ensuring that high-precision data can be obtained each time of measurement, and improving the reliability of measurement.
