[0028] The utility model provides a thickness gauge 100 .

[0029] See also Figure 1 and Figure 2In one embodiment of the utility model, the thickness gauge 100 includes a support frame 1, a first fastener and a measuring assembly 4, the support frame 1 includes a base frame 11 and a top frame 12, the base frame 11 and the top frame 12 enclose a mounting groove 13; the first fastener is passed through the base frame 11 and the top frame 12 so that the base frame 11 and the top frame 12 are rotatably connected; the measuring assembly 4 includes a micrometer 41 and a measuring rod 42, the measuring head 411 of the micrometer 41 is slidably passed through the top frame 12 along the extension direction of the measuring head 411, and the measuring rod 42 is passed through the base frame 11.

[0030] The technical solution of the utility model realizes the rotatable connection between the base frame 11 and the top frame 12 by adopting the first fastener. When the measuring head 411 of the micrometer 41 and the measuring rod 42 are misaligned in the center, the first fastener is loosened until the top frame 12 can be fine-tuned and rotated relative to the base frame 11, thereby driving the measuring head 411 of the micrometer 41 to be fine-tuned. Then the first fastener is tightened to realize the coaxial arrangement of the measuring head 411 of the micrometer 41 and the measuring rod 42, thereby solving the problem of eccentricity between the measuring head 411 and the measuring rod 42 of the micrometer 41. The first fastener can be a screw or a bolt, and the utility model does not impose any restriction on this.

[0031] See also Figure 2 In one embodiment of the utility model, the bottom frame 11 and the top frame 12 are provided with a connecting mounting hole 14, and the mounting hole 14 includes a first hole section 141 and a second hole section 142. The cross-sectional area of ​​the first hole section 141 is larger than the cross-sectional area of ​​the second hole section 142. The first fastener is passed through the mounting hole 14 to connect the bottom frame 11 and the top frame 12, and is accommodated in the mounting hole 14. A limiting step is formed at the connection between the first hole section 141 and the second hole section 142. When the first fastener connects the bottom frame 11 and the top frame 12, the first fastener can be completely accommodated in the mounting hole 14, which can effectively reduce the risk of the first fastener loosening, so that the connection strength and stability of the thickness gauge 100 are higher, and the overall appearance is more beautiful.

[0032] To improve the connection stability between the bottom frame 11 and the top frame 12, please refer to Figure 2In one embodiment of the utility model, the thickness gauge 100 includes two first fasteners, and the bottom frame 11 and the top frame 12 are provided with two mounting holes 14 at intervals, and each first fastener is passed through one mounting hole 14 to connect the bottom frame 11 and the top frame 12. Providing two first fasteners and two mounting holes 14 can provide a greater connection force for the connection between the bottom frame 11 and the top frame 12, ensure a more secure and stable connection, and reduce the risk of loosening. The two first fasteners can evenly share the force at the connection, reduce the possibility of one first fastener bearing the entire load, and ensure a secure positioning, and can also prevent the bottom frame 11 of the thickness gauge 100 from moving relative to the top frame 12 during long-term use.

[0033] To place the thickness gauge 100 in a vertical position, refer to Figure 1 In one embodiment of the utility model, the bottom frame 11 is horizontally arranged on a side facing away from the top frame 12. When using the thickness gauge 100 for measurement, the bottom frame 11 is horizontally placed on a work surface, the measuring head 411 of the micrometer 41 is pulled in a direction away from the measuring rod 42, and the object to be measured is placed between the measuring head 411 and the measuring rod 42, and the measuring head 411 is released, and the thickness of the object to be measured can be obtained, without the need to hold the thickness gauge 100, which is more convenient for measurement.

[0034] To facilitate the mobile placement of the Thickness Gauge 100, please refer to Figure 1 In one embodiment of the utility model, the base frame 11 includes a grip arm 114 and a base 115 connected to each other, and the grip arm 114 is provided with a grip groove 111 connected to the mounting groove 13. When using the thickness gauge 100, the user holds the grip arm 114 and can extend into the grip groove 111. The design of the grip arm 114 and the grip groove 111 can provide a better grip, allowing the user to hold the thickness gauge 100 more easily and reduce the possibility of slipping and loss of control. By setting the grip arm 114 and the grip groove 111, the user can more stably control the movement direction and strength of the thickness gauge 100, improve the accuracy and stability of the operation, reduce the risk of accidental falling, and make the user safer during work.

[0035] See also Figure 1 In one embodiment of the utility model, the grip arm 114 is provided with a plurality of anti-skid grooves 114a arranged at intervals. The plurality of anti-skid grooves 114a can provide more surface area to contact the hand, thereby increasing the friction of the grip arm 114. This helps the user to hold the grip arm 114 more firmly and reduce the possibility of slipping. The anti-skid grooves 114a can also allow the fingers to better fit the surface of the grip arm 114, reducing hand fatigue and discomfort.

[0036] To fix the dial gauge 41, refer to Figure 1In one embodiment of the utility model, the thickness gauge 100 further includes a second fastener 2. The top frame 12 is provided with a through hole 121 and a partition hole 122 connected to the through hole 121. The partition hole 122 separates a part of the structure of the top frame 12 into a first arm 123 and a second arm 124 arranged side by side. A part of the structure of the micrometer 41 is passed through the through hole 121. The second fastener 2 is passed through the first arm 123 and the second arm 124 to fix the micrometer 41 to the top frame 12. The part of the structure of the micrometer 41 is passed through the through hole 121, and the measuring head 411 and the measuring rod 42 of the micrometer 41 are made coaxial. The second fastener 2 is then used to pass through the first arm 123 and the second arm 124 to connect and fix the micrometer 41 to the top frame 12. The second fastener 2 can be a bolt and a nut, or a screw, and the utility model does not limit this.

[0037] See also Figure 1 In one embodiment of the utility model, the base frame 11 is provided with a plug hole 112, and the measuring rod 42 is plugged into the plug hole 112. The plug hole 112 is provided to ensure that the measuring rod 42 is firmly mounted on the base frame 11 for accurate measurement.

[0038] For further information, see Figure 1 and Figure 2 In one embodiment of the utility model, the thickness gauge 100 further includes a third fastener. The base frame 11 is provided with a fastening hole 113 communicating with the plug hole 112. The third fastener is passed through the fastening hole 113 and abuts against the measuring rod 42 in the plug hole 112 to limit the position. The third fastener is passed through the fastening hole 113 and abuts against the measuring rod 42, so that the measuring rod 42 is stably installed in the plug hole 112. The third fastener can be a bolt or a screw, and the utility model does not limit this.

[0039] See also Figure 1 In one embodiment of the utility model, the thickness gauge 100 further includes a base 3, and the side of the bottom frame 11 facing away from the top frame 12 is arranged on the base 3. When using the thickness gauge 100 for measurement, the base 3 is horizontally placed on a work surface, the measuring head 411 of the micrometer 41 is pulled in a direction away from the measuring rod 42, and the object to be measured is placed between the measuring head 411 and the measuring rod 42, and the measuring head 411 is released, and the thickness of the object to be measured can be obtained, and the thickness gauge 100 does not need to be held by hand, which is more convenient for measurement.
