[0026] See also Figures 1 to 8 The utility model provides the following technical solutions: a journal oil tank detection inspection tool, suitable for the situation of rapid on-site inspection of the journal oil tank.

[0027] Specifically, Figure 1 and Figure 3 As shown, a journal oil groove inspection tool comprises a plate body 1; a first inspection head 3 and a second inspection head 4 are respectively provided at two ends of the plate body 1; the first inspection head 3 comprises a first square protrusion 31 and a first arc block 32; the first square protrusion 31 is connected to an end of the plate body 1 away from the second inspection head 4; the first arc block 32 is connected to an end of the first square protrusion 31 away from the plate body 1; both side ends of the first square protrusion 31 extend in a direction away from the first arc block 32.

[0028] The specific implementation process is: holding the non-detection end of the plate body 1, that is, the second detection end 4, and sending the first detection head 3 into the inner cavity of the oil tank 6, that is, completely embedding the first arc block 32 connected to the extension end of the first square protrusion 31 into the oil tank 6 (such as Figure 7 or Figure 8 As shown in the figure, the width, depth and angle of the oil groove 6 are detected by the diameter, radius and arc angle of the first arc block 32, wherein the first detection head 3 and the second detection head 4 are set to the maximum value and minimum value allowed by the standard, and then, after the first detection head 3 performs detection, the second detection head 4 is used for detection, thereby realizing on-site rapid detection without the need for separate detection such as profilometer, which is efficient and easy to operate.

[0029] In this embodiment, different detection heads (such as Figure 5 , Figure 7 , Figure 8 As shown), specifically, the angle of the connecting portion between the two ends of the first square protrusion 31 and the first arc block 32 can be adjusted; in addition, the structure of the second detection head 4 is consistent with that of the first detection head 1, with only a difference in size, and both detection heads can be set to a screw connection with the end of the plate body 1, which can also facilitate the replacement of different types of oil tank 6 detection heads, further broadening the scope of use of the inspection fixture.

[0030] Specifically, Figure 2 and Figure 4As shown, the plate body 1 includes a first L-shaped plate 11 and a second L-shaped plate 12; a first square protrusion 31 is arranged at one end of the first L-shaped plate 11; a second detection head 4 is arranged at one end of the second L-shaped plate 12 away from the first L-shaped plate 11; the first L-shaped plate 11 is slidably connected with the second L-shaped plate 12. A sliding groove 111 is arranged at one end of the first L-shaped plate 11 away from the first square protrusion 31; a slider 121 is arranged at one end of the second L-shaped plate 12 away from the second detection head 4; the slider 121 is embedded in the sliding groove 111. A block 122 is arranged opposite to the end of the slider 121 that passes through the sliding groove 111; the end of the first L-shaped plate 11 close to the sliding groove 111 is provided with a slot 112 for the block 122 to be embedded. A stopper is arranged at one end of the slider 121 that passes through the sliding groove 111.

[0031] By dividing the plate body 1 into a first L-shaped plate 11 and a second L-shaped plate 12, it is convenient to lengthen the gauge, so that it is convenient to hold and operate, and it is convenient to retract; wherein, the first L-shaped plate 11 is slidably connected with the second L-shaped plate 12, that is, by extending a slider 121 provided on the second L-shaped plate 12 and embedding it into a slide groove 111 provided on the side of the first L-shaped plate 11, the first L-shaped plate 11 and the second L-shaped plate 12 are slidably connected, thereby lengthening the overall length of the gauge.

[0032] In addition, in order to ensure the stability of the gauge before and after the extension, the two ends of the slideway 111 are provided with corresponding slots 112 (such as Figure 6 As shown), the slider 121 can be limited before and after the extension, so that the first L-shaped plate 11 and the second L-shaped plate 12 will not slide out of the detection process; further, to ensure that the slider 121 does not slide out of the slide groove 111, a stopper is provided at the top or bottom of the slider 121.

[0033] Specifically, Figure 2 and Figure 5 As shown, the first L-shaped plate 11 is connected to the first square protrusion 31 via a trapezoidal plate 5. Two opposite sides of the trapezoidal plate 5 are provided with grooves.

[0034] The narrow end of the trapezoidal plate is connected to the first square protrusion 31, and the wide end of the trapezoidal plate is connected to the first L-shaped plate 11, so that it is convenient to extend the first detection head 3 into the oil tank 6 during detection to avoid being blocked by the structure near the oil tank 6 during detection; in addition, in order to avoid the hand-held inspection tool from sliding easily due to sweating of the hands after multiple detections, a groove for handholding is further provided in the middle of the trapezoidal plate 5, and an anti-slip rubber layer is further provided in the groove; similarly, the second L-shaped plate 12 is provided with the same structure as the first L-shaped plate 11.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
