[0041] Please refer to Figure 1-8 as shown, a thickness gauge for detection, and the thickness gauge for detection includes:

[0042] a U-shaped support frame 1, and support plates 2 are fixedly arranged on both sides of the U-shaped support frame 1;

[0043] an insertion moving assembly 3, the insertion moving assembly 3 is fixedly arranged on the upper surface of the U-shaped support frame 1, a force control assembly 4 is fixedly arranged on the side of the insertion moving assembly 3, a thickness gauge 5 is fixedly connected to the bottom end of the force control assembly 4, and the insertion moving assembly 3 can linearly move to drive the force control assembly 4 and the thickness gauge 5 to move;

[0044] a gap cleaning unit 6, the gap cleaning unit 6 is fixedly arranged on the side of the U-shaped support frame 1, the gap cleaning unit 6 is connected to the insertion moving assembly 3, and the gap cleaning unit 6 can automatically spray gas during detection;

[0045] Through the above technical solution, the setting of the insertion moving component 3 can play a role in positioning the insertion, so that the feeler gauge 5 can always be inserted vertically into the gap for measurement. At the same time, in order to solve the problem in the prior art that it is easy to insert too tightly or too loosely during manual insertion measurement, the present application designs a force control component 4. Through the force control component 4, the insertion force can be controlled when the feeler gauge 5 is inserted into the gap for measurement, which plays a function of fixing the force and avoids the force error of manual operation. Further, in order to avoid the influence of particulate foreign matters inside the detection gap on the detection, the present application sets a gap cleaning unit 6. Through the gap cleaning unit 6, the gap can be automatically flushed and cleaned during the insertion detection, which is convenient to operate and flexible to use.

[0046] The insertion moving component 3 includes a rectangular fixed column 301, a moving plate 302, a moving slider 303, a threaded rod 304, a first bevel gear 305 and a rotating disc 306. The rectangular fixed column 301 is fixedly arranged on the upper surface of the U-shaped support frame 1. The interior of the rectangular fixed column 301 is provided with an inner cavity. A moving slider 303 is slidably connected in the inner cavity of the rectangular fixed column 301. A moving plate 302 is slidably connected to the side wall of the rectangular fixed column 301. The moving slider 303 and the moving plate 302 are fixedly connected to each other.

[0047] A threaded rod 304 is rotatably connected between the upper and lower walls of the inner cavity of the rectangular fixed column 301. The threaded rod 304 passes through the moving slider 303 and is in threaded cooperation with the moving slider 303. A first bevel gear 305 is fixedly arranged at the upper end of the threaded rod 304. Through this technical solution, the rotation of the threaded rod 304 can drive the moving slider 303 to move, thereby driving the moving plate 302 to move, so as to realize the linear movement function of the feeler gauge 5, and thus ensure that the feeler gauge 5 is inserted linearly into the gap for measurement, avoiding the phenomenon of deviation.

[0048] A rotating shaft 307 is rotatably connected to the side wall of the rectangular fixed column 301. One end of the rotating shaft 307 is fixedly connected with a rotating disc 306. A handle 309 is fixedly arranged on the side wall of the rotating disc 306. The other end of the rotating shaft 307 extends into the inner cavity of the rectangular fixed column 301. One end of the rotating shaft 307 is fixedly connected with a second bevel gear 308. The second bevel gear 308 meshes with the first bevel gear 305. Through this technical solution, manually rotating the rotating disc 306 can drive the rotating shaft 307 to rotate. Furthermore, the rotation of the rotating shaft 307 can drive the second bevel gear 308 to rotate, thereby driving the first bevel gear 305 to rotate. Then, the rotation of the first bevel gear 305 drives the threaded rod 304 to rotate. Thus, the rotation of the threaded rod 304 drives the moving slider 303 to move, and further drives the moving plate 302 to move, realizing the function of linear movement;

[0049] The force control assembly 4 includes a moving rod 401, a fixed circular plate 402, a control spring 403, an indicating plate 404, and a scale rod 406. The moving rod 401 penetrates through the moving plate 302 and is slidably matched with the moving plate 302. The moving rod 401 penetrates through the U-shaped support frame 1 and is slidably matched with the U-shaped support frame 1. A feeler gauge 5 is fixedly arranged at the bottom end of the moving rod 401;

[0050] The top end of the moving rod 401 is fixedly connected with a fixed circular plate 402. One end of a control spring 403 is fixedly connected to the bottom surface of the fixed circular plate 402. The other end of the control spring 403 extends to the upper surface of the moving plate 302 and is fixedly connected to the moving plate 302. Through this technical solution, when the moving plate 302 moves linearly downward, it can drive the moving rod 401 to move downward, thereby driving the feeler gauge 5 to move downward, so that the feeler gauge 5 is inserted into the gap. After the feeler gauge 5 is inserted into the gap, the continuous downward movement of the moving plate 302 will cause the control spring 403 to stretch. Thus, the elastic force generated by the stretching of the control spring 403 is applied to the feeler gauge 5 through the moving rod 401, giving the feeler gauge 5 a downward pressure. Furthermore, by controlling the deformation amount of the control spring 403, the magnitude of the elastic force is controlled, thereby controlling the magnitude of the force for the feeler gauge 5 to be inserted, and avoiding the phenomenon of being inserted too tightly due to excessive force when manually inserting;

[0051] The connecting plate 405 is fixedly arranged at the side of the moving plate 302. A scale rod 406 is fixedly connected to the upper surface of the connecting plate 405. The scale rod 406 penetrates through the indicating plate 404 and is in sliding fit with the indicating plate 404. The indicating plate 404 is fixedly arranged on the upper surface of the fixed circular plate 402. Through this technical solution, by the moving distance of the user penetrating the scale rod 406, the stretching length of the control spring 403 can be more intuitively judged, so as to conveniently control the force.

[0052] The gap cleaning unit 6 includes a first connecting plate 601, a second connecting plate 602, a connecting rod 603, a fixed cylinder 604, an input pipe 608 and a nozzle 607. The first connecting plate 601 is arranged on the side wall of the rotating disc 306 and is rotatably connected to the rotating disc 306. The bottom end of the first connecting plate 601 is rotatably connected to a second connecting plate 602. The bottom end of the second connecting plate 602 is fixedly connected to a connecting rod 603. Through this technical solution, when the rotating disc 306 is rotated, one end of the first connecting plate 601 can be driven to perform a circular motion by the rotation of the rotating disc 306, so as to drive the connecting rod 603 to perform a reciprocating up and down motion.

[0053] The fixed cylinder 604 is fixedly arranged on the upper surface of the support plate 2. A moving piston 605 is slidably connected in the inner cavity of the fixed cylinder 604. The connecting rod 603 extends into the inner cavity of the fixed cylinder 604 and is fixedly connected to the moving piston 605. Through this technical solution, the reciprocating up and down motion of the connecting rod 603 can drive the moving piston 605 to perform a reciprocating up and down movement in the inner cavity of the fixed cylinder 604.

[0054] An output pipe 606 is fixedly connected to the bottom end of the inner cavity of the fixed cylinder 604. One end of the output pipe 606 is fixedly connected to a nozzle 607. An output one-way valve is installed on the output pipe 606. An input pipe 608 is fixedly connected to the bottom end of the inner cavity of the fixed cylinder 604. An input one-way valve is installed on the input pipe 608. Through this technical solution, when the moving piston 605 moves upward in the inner cavity of the fixed cylinder 604, gas can be sucked through the input pipe 608 so that the gas enters the inner cavity of the fixed cylinder 604. When the moving piston 605 moves downward, the gas in the inner cavity of the fixed cylinder 604 can be output through the output pipe 606 and thus sprayed out through the nozzle 607 to perform spray cleaning on the inserted gap, avoiding the detection error phenomenon caused by foreign particles. Through this technical solution, the function of automatic cleaning during detection is realized.

[0055] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
