Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 , this embodiment provides a technical solution: an inspection tool for measuring gaps in a narrow space, comprising a fixed bin 1 and a driving mechanism 4;

[0026] Fixed bin 1: Its front end is connected to the measuring seat 2 through a clamping mechanism 3, and a scale bar 313 is provided on the rear end of the upper surface of the measuring seat 2. The clamping mechanism 3 includes a fixed shaft 31 and a clamping arm 32. The fixed shaft 31 is symmetrically fixedly connected to the front end of the fixed bin 1. The upper end of the fixed shaft 31 is rotatably connected to the clamping arm 32. The rear end of the measuring seat 2 is fixedly connected to the connecting column 5. The middle parts of the relative inner surfaces of the two clamping arms 32 are both installed in conjunction with the connecting column 5. The clamping mechanism 3 also includes a driving seat 34 and a slide rail 35. The slide rail 35 is fixedly connected to the interior of the fixed bin 1.

The clamping mechanism 3 also includes a torsion spring 33, which is fixedly connected between the clamping arm 32 and the bottom wall of the fixed chamber 1. The torsion spring 33 is movably sleeved on the outer surface of the laterally adjacent fixed shaft 31. The measuring seat 2 is inserted into the interior of the rectangular narrow space gap. When the measuring seat 2 is inserted and stabilized in the rectangular narrow space gap, the width of the rectangular narrow space gap is displayed according to the cooperation between the inner edge of the rectangular narrow space gap and the scale bar 3 13;

[0027] Driving mechanism 4: It is used for opening and closing control of the clamping mechanism 3. The driving mechanism 4 includes a rack plate 41, a driving gear 42 and a rotating shaft 43. The rack plate 41 is fixedly connected to the right end of the driving seat 34, and the rotating shaft 43 is rotatably connected to the right end of the fixed bin 1. The upper end of the rotating shaft 43 is fixedly connected to the driving gear 42, and the driving gear 42 is meshed with the rack plate 41. A notch is provided at the right end of the fixed bin 1, and the right end of the driving gear 42 extends to the outside of the notch. The driving mechanism 4 also includes a protective cover 44, which is hinged to the right end of the fixed bin 1 through a hinge. The protective cover 44 is installed in conjunction with the notch and rotates the driving gear 42 backward. The driving gear 42 rotates to move the rack plate 41 forward, thereby driving the driving seat 34 to move forward inside the slide rail 35. The front end of the driving seat 34 pushes the two clamping arms 32, and the two clamping arms 32 both rotate around The central axis of the vertically adjacent fixed shaft 31 moves in the direction away from the center of the fixed chamber 1, and the clamping arms 32 rotate outward to cause the vertically adjacent torsion springs 33 to twist the special force, and then the connecting column 5 is placed between the two clamping arms 32, and then the driving gear 42 is rotated forward. The driving gear 42 rotates to cause the rack plate 41 to move backward, thereby driving the driving seat 34 to move backward inside the slide rail 35. At the same time, the elastic force of the torsion spring 33 acts on the vertically adjacent clamping arms 32, and the clamping arms 32 move around the central axis of the vertically adjacent fixed shaft 31 in the direction close to the center of the fixed chamber 1. The clamping arms 32 achieve stable clamping of the connecting column 5, thereby achieving stable installation of the measuring seat 2. Then the driving gear 42 is stopped, and the protective cover 44 is rotated downward to avoid accidental contact with the driving gear 42 when measuring the gap in a narrow space.

[0028] Wherein: the rear end of the fixed chamber 1 is provided with a threaded hole 6, the internal thread of the threaded hole 6 is connected to a screw 7, the rear end of the screw 7 is fixedly connected to a measuring column 8, the measuring column 8 is a tapered column, and the outer surface of the measuring column 8 is provided with a scale bar 12. The measuring column 8 is inserted into the inner part of the circular narrow space gap. When the measuring column 5 is inserted and stabilized in the inner part of the circular narrow space gap, the inner edge of the circular narrow space gap cooperates with the scale bar 12 to display the width of the circular narrow space gap;

[0029] Among them: the upper end of the fixed bin 1 is fixedly connected to a fixed column 9, and the middle part of the fixed column 9 is rotatably connected to five measuring plates 10. The thickness of the five measuring plates 10 decreases from bottom to top. The rear end of the upper surface of the measuring plate 10 is provided with a scale bar 11. According to the thickness of the narrow space gap, the corresponding measuring plate 10 is selected, and then the measuring plate 10 is placed inside the narrow space gap. The edge of the narrow space gap cooperates with the scale bar 11 to display the depth of the narrow space gap.

[0030] The working principle of the inspection tool for measuring gaps in narrow spaces provided by the present invention is as follows: when working, the operator first rotates the driving gear 42 backward, and the driving gear 42 rotates to make the rack plate 41 move forward, thereby driving the driving seat 34 to move forward inside the slide rail 35. The front end of the driving seat 34 pushes the two clamping arms 32, and the two clamping arms 32 both move around the central axis of the vertically adjacent fixed shaft 31 in the direction away from the center of the fixed bin 1, and the outward rotation of the clamping arms 32 causes the vertically adjacent torsion springs 33 to twist the special The force is applied, and then the personnel places the connecting column 5 between the two clamping arms 32, and then the personnel rotates the driving gear 42 forward. The driving gear 42 rotates to make the rack plate 41 move backward, thereby driving the driving seat 34 to move backward inside the slide rail 35. At the same time, the elastic force of the torsion spring 33 acts on the vertically adjacent clamping arms 32. The clamping arms 32 move around the central axis of the vertically adjacent fixed shaft 31 in the direction close to the center of the fixed warehouse 1. The clamping arms 32 achieve stable clamping of the connecting column 5, thereby achieving stable installation of the measuring seat 2. Then the personnel stops rotating the driving gear 42, and then the personnel rotates the protective cover 44 downward to prevent the personnel from accidentally touching the driving gear 42 when measuring the narrow space gap. Then the personnel thread the screw 7 into the inside of the threaded hole 6 to achieve stable installation of the measuring column 8. Then the personnel inserts the measuring seat 2 into the rectangular narrow space gap. When the measuring seat 2 is stably inserted in the rectangular narrow space gap, the personnel cooperates with the scale bar three 13 according to the inner edge of the rectangular narrow space gap to display the width of the rectangular narrow space gap. The personnel inserts the measuring column 8 into the circular narrow space gap. When the measuring column 5 is stably inserted in the circular narrow space gap, the personnel cooperates with the scale bar two 12 according to the inner edge of the circular narrow space gap to display the width of the circular narrow space gap. Then the personnel selects the corresponding measuring plate 10 according to the thickness of the narrow space gap, and then places the measuring plate 10 inside the narrow space gap. The edge of the narrow space gap cooperates with the scale bar one 11 to display the depth of the narrow space gap.
