Description

Technical Field

[0001] This utility model relates to the field of irregular-shaped vernier calipers, specifically an irregular-shaped caliper for measuring the wall thickness of low-carbon steel radiators. Background Technology

[0002] In the production, installation and quality inspection of low-carbon steel radiators, accurate measurement of their wall thickness is a key step in ensuring the product's heat dissipation performance, structural strength and assembly compatibility.

[0003] To improve heat dissipation efficiency, low-carbon steel radiators are often designed with arc-shaped protrusions, arc-shaped grooves, or irregularly shaped bending structures on their surface. However, the measuring head of a conventional vernier caliper is mostly flat or a simple straight line, which cannot effectively fit the arc-shaped structure of the radiator, resulting in deviations in the measurement results.

[0004] Currently, the industry requires cutting the radiator to measure the wall thickness of low-carbon steel radiators, and then measuring the cross-section to determine the wall thickness. While this method is feasible, users cannot measure the wall thickness of the installed low-carbon steel radiators themselves, causing considerable inconvenience. Utility Model Content

[0009] The sliding measuring head is also equipped with a protective tube, which increases the structural strength of the sliding claw head and also protects the sliding claw head and the fixed claw head.

[0010] As a preferred technical solution of this utility model, the upper and lower ends of the horizontal part are respectively provided with an upper arc surface and a lower arc surface, and the arc of the upper arc surface and the lower arc surface are the same.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] like Figures 1 to 5 As shown, this utility model discloses an irregularly shaped caliper for measuring the wall thickness of low-carbon steel radiators. The technical solution adopted is as follows: it includes a vernier 1 and a ruler 2. The vernier 1 is slidably connected to the ruler 2. The ruler 2 is provided with a main scale. A sliding measuring head 4 and a fixed measuring head 3 are respectively connected to the vernier 1 and the ruler 2, and the sliding measuring head 4 and the fixed measuring head 3 are in corresponding positions.

[0027] The fixed measuring head 3 is L-shaped, including a horizontal part and a vertical part. The horizontal part has an arc-shaped structure, which is suitable for measuring low carbon steel radiators with different structures. The vertical part is equipped with a fixed claw head 5.

[0028] The horizontal part is provided with an upper arc-shaped surface 32 and a lower arc-shaped surface 31 at its upper and lower ends, respectively, and the upper arc-shaped surface 32 and the lower arc-shaped surface 31 have the same curvature.

[0029] The sliding measuring head 4 is equipped with a sliding claw head 6, which is coaxially arranged with the fixed claw head 5.

[0030] The sliding measuring head 4 is also provided with a protective tube 7, which increases the structural strength of the sliding claw head 6 and is used to protect the sliding claw head 6 and the fixed claw head 5.

[0031] The protective tube 7 includes an outer protective tube 71 and an inner protective tube 72. The inner protective tube 72 is installed on the sliding measuring head 4, and the outer protective tube 71 is fitted onto the inner protective tube 72. The inner protective tube 72 increases the structural strength of the sliding claw head 6 and prevents it from being deformed by accidental contact, which would affect the measurement accuracy.

[0032] The inner wall of the protective outer tube 71 is also provided with a protruding rib 73, which fits in contact with the sliding claw head 6 and the fixed claw head 5. The protective inner tube 72 is provided with a slot 74 that matches the protruding rib 73. There are three sets of protruding ribs 73 arranged in a ring array inside the protective outer tube 71. When stored, the protruding ribs 73 on the protective outer tube 71 contact the fixed claw head 5 to protect it.

[0033] A limiting structure is also provided between the protective outer tube 71 and the protective inner tube 72. The limiting structure includes a fixed magnet 79, a first positioning magnet 76, and a second positioning magnet 78. The fixed magnet 79 is installed on the protective outer tube 71 and is located at the end of the protective outer tube 71 near the sliding measuring head 4. The first positioning magnet 76 and the second positioning magnet 78 are respectively installed on the protective inner tube 72 and the sliding measuring head 4, respectively corresponding to the protective state and the storage state of the protective tube 7.

[0034] The protective inner tube 72 has an annular groove 75, the first positioning magnet 76 is installed in the annular groove 75, and the sliding measuring head 4 has a receiving groove 77 for installing the second positioning magnet 78.

[0035] The working principle of this utility model:

[0036] Push the protective outer tube 71 toward the sliding measuring head 4 until the fixed magnet 79 and the second positioning magnet 78 are attracted together. At this time, the protective tube 7 is in the retracted state, and the sliding claw head 6 and the fixed claw head 5 are fully exposed, and the measurement operation can be performed.

[0037] Based on the arc-shaped protrusions or grooves of the part of the low-carbon steel radiator to be measured, tilt the vernier caliper so that the fixed measuring head 3 mates with the upper arc surface 32 and the lower arc surface 31, causing the fixed claw head 5 to be located inside the radiator. Then push the vernier 1, causing the sliding measuring head 4 to move towards the fixed measuring head 3, until the sliding claw head 6 and the fixed claw head 5 clamp the part of the radiator to be measured. At this time, read the values ​​of the main scale of the caliper body 2 and the secondary scale of the vernier caliper 1, which is the wall thickness of the radiator.

[0038] After the measurement is completed, push the protective outer tube 71 toward the fixed measuring head 3 until the fixed magnet 79 and the first positioning magnet 76 are attracted. At this time, the protective outer tube 71 completely covers the sliding claw head 6 and the fixed claw head 5 to prevent the claw head from being hit, worn or corroded by the environment. When storing, the calipers can be put into a special packaging box to further enhance the protection effect.
