[0021] The technical schemes in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Embodiment one: please refer to Figures 1-6The utility model provides a part opening size detection device, including sleeve 1, when detecting conventional part opening size, first fixed plate 5 is tightly attached to one side of the opening part, press press plate 9, can extrude hinged plate 10 through movable rod 8, hinged plate 10 rotates in the recess on the back of measuring rod 3, when hinged plate 10 moves to the recess in the measuring rod 3 inside, can make that limiting rod 7 is separated from the inner wall of sleeve 1, when pulling pull plate 2, can make that measuring rod 3 moves, and then can drive mobile measuring plate 4 to move, and can realize the purpose of detecting the size of part opening by the cooperation of fixed plate 5, because the recess of pull plate 2 one side inner wall is fixedly installed with spring 11, spring 11 exerts the elastic force to hinged plate 10, makes hinged plate 10 drive limiting rod 7 always have the tendency to the outside, limiting rod 7 can be tightly attached to the inner wall of sleeve 1 at this time, thereby realizes the location of measuring rod 3, and then realizes the location of mobile measuring plate 4, after press press plate 9, when can pull pull plate 2, measuring rod 3 slides in sleeve 1, when measuring rod 3 moves to the position, limiting rod 7 is contacted with the inner wall of the recess of pull plate 2, plays certain location effect, guarantees the stability of the position of measuring rod 3, and mobile measuring plate 4 will move with measuring rod 3 in the through -hole under sleeve 1, until the one side of mobile measuring plate 4 is tightly attached to one side of part opening, in the process of pulling pull plate 2, simultaneously, the slide bar 6 of measuring rod 3 top slides in the slide groove of sleeve 1 top inner wall, further guarantees the stability of measuring rod 3 sliding, at this time, the position of indicating needle 12 at the mobile measuring plate 4 left side of measuring rod 3 on the upper lateral scale of sleeve 1 front observation hole is observed, namely can accurately read the size of part opening.

[0023] Example two: please refer to Figures 1-6When the opening size of the part needs to be detected, the fixed plate 5 is first placed on one side of the opening of the part to be detected, and then the pressing plate 9 is pressed. When the pressing plate 9 moves, the movable rod 8 can be moved in the groove of the pull plate 2. The outer circle of the movable rod 8 in the groove of the pull plate 2 is provided with a limiting plate 13, which plays a limiting role on the movable rod 8 and prevents the movable rod 8 from being pulled out of the pull plate 2. When the movable rod 8 is moved by the pressing plate 9, the hinged plate 10 can be pushed to move at this time. The hinged plate 10 can overcome the elastic force of the spring 11 to rotate, so that the limiting rod 7 is retracted into the groove of the pull plate 2. At this time, the limiting rod 7 is separated from the inner wall of the sleeve 1. At this time, the pull plate 2 can be pulled to move, so that the pull plate 2 can be easily pulled to adjust the position of the measuring rod 3. When the measuring rod 3 moves, the movable measuring plate 4 can be moved. When the movable measuring plate 4 is attached to the opening of the part, the pressing plate 9 is released. The elastic force of the spring 11 resets the hinged plate 10, the limiting rod 7 extends and can abut against the inner wall of the sleeve 1, so as to limit the measuring rod 3, thereby limiting the movable measuring plate 4. Then, the position of the indicating needle 12 on the scale is observed to obtain the opening size of the part. This operation mode can also be used to flexibly measure the size of the part opening in a narrow space, thereby improving the applicability of detection.

[0024] The sliding connection of the sleeve 1 and the measuring rod 3, the matching structure of the sliding rod 6 and the sliding groove, and the cooperation of the indicating needle 12 and the scale on the front observation hole of the sleeve 1 make the sliding of the measuring rod 3 in the sleeve 1 more stable and smooth, effectively guaranteeing the accuracy of the measurement. The movable measuring plate 4 is movable in the lower hole of the sleeve 1 and can directly contact the opening of the part. The reading of the measurement result is intuitive and accurate. This design greatly simplifies the measurement operation, improves the measurement efficiency, and provides convenience for rapid detection of the opening size of the part.

[0025] The hinged plate 10, the limiting rod 7, the spring 11, the movable rod 8, the pressing plate 9 and other components are arranged to enable the device to be flexibly adjusted and kept stable during measurement. The limiting rod 7 is made of rubber and can limit the function of the measuring rod 3. After the measuring rod 3 completes the opening size measurement of the part, the elastic force of the spring 11 on the hinged plate 10 can make the limiting rod 7 tightly abut against the inner wall of the sleeve 1, thereby realizing the limiting function of the measuring rod 3. The limiting and unlocking of the measuring rod 3 are facilitated, the measuring rod 3 is stably stopped at the appropriate position, the stability and reliability of the measurement are further improved, and the detection requirements of the opening size of the part can be met.

[0026] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
