[0002] The number wheel is a structure in the combination lock. The correct password is arranged by controlling the number wheel on the combination lock to open the combination lock. In order to reduce the discomfort of fingers when touching the number wheel, the characters on the number wheel are generally polished and the polished characters are inspected to ensure that the number wheel meets the factory requirements. In traditional technology, the number wheel is generally held manually to control the characters on the number wheel to be close to the visual inspection mechanism, and the characters on the number wheel are inspected at the inspection position of the visual inspection mechanism to see if they meet the standards. However, during the inspection of the number wheel, the number wheel needs to be rotated so that the characters at different positions on the number wheel are at the inspection position for inspection by the visual inspection mechanism. However, when the number wheel is manually rotated, it is difficult to quickly control the characters on the number wheel to be at the inspection position after the number wheel is rotated, which increases the inspection time of the number wheel and results in a technical problem of low inspection efficiency of the number wheel.

[0032] like Figure 1 As shown, it is a number wheel inspection fixture 100 shown in the present utility model, such as Figure 4 As shown, the number wheel checker 100 is used to install the number wheel 200.

[0033] like Figure 1 As shown, the number wheel inspection fixture 100 includes: a base 10, a support assembly 20 and a stopper 30, wherein the base 10 is used to install the support assembly 20 and the stopper 30, the support assembly 20 is rotatably connected to the base 10 and is used to install the number wheel 200, and the stopper 30 is used to limit the rotation position of the support assembly 20 to quickly control the characters on the support assembly 20 to be positioned at a predetermined detection position.

[0034] Below, combined Figures 1 to 5 , the number wheel checking fixture 100 is further described.

[0035] like Figure 1 to Figure 2As shown, the base 10 includes a bottom block 11 and a mounting block 12. The bottom block 11 is used to support the mounting block 12, and the bottom block 11 and the mounting block 12 are vertically arranged. The mounting block 12 is provided with a rotating hole 121 and a positioning hole 122. The rotating hole 121 is connected to the positioning hole 122. The rotating hole 121 is used for rotational connection of the support assembly 20, and the positioning hole 122 is used to install the limit member 30.

[0036] like Figure 3 As shown, the support assembly 20 is used to install the number wheel 200. The support assembly 20 is rotatably connected to the rotating hole 121 to drive the number wheel 200 to rotate. Specifically, the support assembly 20 includes a rotating shaft 21 and a positioning member 22. The rotating shaft 21 is rotatably connected to the rotating hole 121. The positioning member 22 is detachably connected to the rotating shaft 21 and forms a positioning space 23 with the rotating shaft 21 for installing the number wheel 200. The positioning member 22 includes a control part 221 and a pressing part 222. The side wall of the control part 221 has an anti-slip surface 223. The pressing part 222 and the rotating shaft 21 form a positioning space 23.

[0037] like Figure 3 As shown, the rotating shaft 21 includes a connecting shaft 211, a supporting shaft 212, a retaining ring 213 and a rotating shaft 214. The connecting shaft 211 is threadedly connected to the positioning member 22, and forms a positioning space 23 with the supporting shaft 212 and the retaining ring 213. The rotating shaft 214 is rotatably set in the rotating hole 121 and is provided with a positioning groove 215. The positioning groove 215 is set corresponding to the position of the rotating hole 121. There are multiple positioning grooves 215, and each positioning groove 215 is set around the axis of the rotating shaft 214.

[0038] Furthermore, if Figure 3 and Figure 5 As shown, the support assembly 20 further includes a positioning bar 24, which is mounted on the rotating shaft 214 of the rotating shaft 21 and is arranged corresponding to the position of the positioning groove 215. The number wheel 200 is provided with a slot 201 that cooperates with the positioning bar 24. The positioning bar 24 and the number wheel 200 facilitate the rapid correspondence between the position of the number wheel 200 and the position of the positioning groove 215, so as to reduce the time consumed when the characters on the number wheel 200 correspond to the positions of the positioning groove 215, thereby achieving the purpose of improving the alignment efficiency of the number wheel 200.

[0039] Furthermore, if Figure 3 As shown, the support assembly 20 also includes a control member 25 and a baffle 26. The control member 25 is a hand-tightened nut connected to one end of the rotating shaft 21 away from the positioning member 22. The baffle 26 is a gasket disposed between the rotating shaft 21 and the control member 25.

[0040] like Figure 1As shown, the stopper 30 is installed in the positioning hole 122, and penetrates the rotation hole 121 and is inserted into one of the positioning grooves 215, wherein the stopper 30 is a stud and is threadedly connected with the positioning hole 122, as shown in FIG. Figure 5 As shown, when in use, by rotating the limit member 30, the limit member 30 is controlled to be inserted into the positioning groove 215 in the positioning hole 122, so that the rotation shaft 21 is prevented from rotating by the limit member 30, so as to achieve the purpose of positioning the position of the characters of the number wheel 200 on the rotation shaft 21. When the limit member 30 is controlled to be away from the positioning groove 215 in the positioning hole 122 and the limit member 30 is separated from the positioning groove 215, the rotation shaft 21 can be controlled to rotate, so as to drive the number wheel 200 to rotate, so that the characters at different positions on the number wheel 200 are at the detection position for detection by the visual detection mechanism.

[0041] The beneficial effects of the number wheel inspection fixture 100 shown in the utility model are as follows: the base 10 is used to rotatably install the support assembly 20, the support assembly 20 is used to install the number wheel 200, the limiting member 30 is installed in the positioning hole 122, and the rotation hole 121 is penetrated to be inserted into one of the positioning grooves 215, so that the supporting assembly 20 on which the number wheel 200 is installed can be controlled to rotate under the support of the base 10, and the number wheel 200 is positioned by the cooperation between the limiting member 30 and the positioning groove 215 of the support assembly 20, so that the characters on the number wheel 200 can be quickly placed at the detection position, thereby reducing the detection time of the number wheel 200 and achieving the purpose of improving the detection efficiency of the number wheel 200.
