DETAILED DESCRIPTION

[0028] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the present application, but the present application can also be implemented in other ways different from the description, and those skilled in the art can make similar generalizations without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0030] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or selectively excluded from other embodiments.

[0031] Embodiment 1, refer to Figures 1 to 9For the first embodiment of the present application, the embodiment provides an irregular product size measuring device, comprising a limiting frame 100, the limiting frame 100 is provided with a line sleeve 101; a plurality of top pushing pieces 200 arranged in a horizontal array, the top pushing piece 200 comprises a push rod 201 slidingly arranged in the limiting frame 100, and a top pushing end 203 arranged at the end of the push rod 201, the top pushing end 203 is provided with an arc-shaped embedding groove 203a; a measuring piece 300, comprising a winding disc 301 arranged on the limiting frame 100, and a measuring rope 302 wound on the winding disc 301, the surface of the measuring rope 302 is provided with a scale.

[0032] It should be noted that one end of the measuring rope 302 is fixedly arranged on the surface of the limiting frame 100 away from the winding disc 301, the measuring rope 302 passes through the line sleeve 101 and is placed in the arc-shaped embedding groove 203a, and the winding and unwinding of the measuring rope 302 can be realized by rotating the winding disc 301.

[0033] In use, all the push rods 201 are in a state of sliding out of the limiting frame 100, and the measuring device is attached to the profile of the measured object by abutting the top pushing end 203 against the measuring rope 302. During the attachment process, since the surface of the measured object is irregular, the corresponding push rod 201 will slide in the limiting frame 100 according to the surface profile of the measured object, so that the top pushing end 203 of the push rod 201 abuts against the surface of the measured object. By limiting the measuring rope 302 through the arc-shaped embedding groove 203a, the measuring rope 302 can better fit the surface of the measured object, and the length of the measuring rope 302 can be appropriately wound and unwound to match the length of the profile surface. Through the device, the difficulty of measurement can be reduced, the error during measurement can be reduced by improving the fitting effect, and the measurement data can be read through the scale on the measuring rope 302 during reading.

[0034] Specifically, the limiting frame 100 is provided with a lower limiting groove 102, and the lower limiting groove 102 is slidingly provided with a lower limiting piece 104; in this embodiment, each top pushing piece 200 is correspondingly provided with one lower limiting piece 104.

[0035] Further, the push rod 201 is provided with a spring 202, one end of the spring 202 is provided with a top pushing sleeve 202a; in this embodiment, the top pushing sleeve 202a is slidingly arranged in the interior of the push rod 201.

[0036] Preferably, the surface of the push rod 201 is provided with a first straight groove 201a; the lower limiting piece 104 comprises a lower connecting rod 104a and a lower sliding plate 104b provided on the lower connecting rod 104a, and the end of the lower connecting rod 104a away from the lower sliding plate 104b is provided with a lower fan-shaped sliding block 104c; in the embodiment, the outer wall of the lower connecting rod 104a is in sliding connection with the inner wall of the first straight groove 201a, the lower sliding plate 104b is in sliding connection with the lower limiting groove 102, and the lower fan-shaped sliding block 104c is in sliding connection with the inside of the push rod 201.

[0037] In use, the spring 202 can push the push rod 201 to have a sliding trend out of the limiting frame 100, and the lower limiting piece 104 can slide in the lower limiting groove 102, so that the position of the single push piece 200 can be adjusted; when the measuring device is not attached to the surface of the measured object, the push rod 201 can be kept in the state of extending out of the limiting frame 100, and when the measuring device is attached to the surface of the measured object, the spring 202 can make the push end 203 in the state of attaching to the surface of the measured object, so that the measuring rope 302 can better attach to the surface of the measured object, and the measurement accuracy is improved; and when encountering a bending change position, the push piece 200 can be slid to make the lower limiting piece 104 slide in the lower limiting groove 102, so that the abutting position of the push end 203 can be adjusted to be close to the bending point, the measuring rope 302 can be pressed on the surface of the measured object, and the attachment effect is improved.

[0038] Further, the surface of the push end 203 is provided with an abutting plate 204, and the abutting plate 204 is provided with a straight groove 204a; in the embodiment, the straight groove 204a and the arc-shaped embedded groove 203a are perpendicular.

[0039] The surface of the push rod 201 is provided with a communication groove 201b and a second straight groove 201c, the first straight groove 201a and the second straight groove 201c are communicated through the communication groove 201b; in the embodiment, the operator can press the push end 203 to make the spring 202 compressed, the push rod 201 slides into the limiting frame 100, the lower connecting rod 104a slides into one end of the communication groove 201b from the end of the first straight groove 201a away from the communication groove 201b, the lower connecting rod 104a slides into the second straight groove 201c through the communication groove 201b by rotating the push rod 201, at this time, the pressing of the push end 203 is stopped, the push rod 201 is reset by the elastic force of the spring 202, the lower connecting rod 104a slides to the end of the second straight groove 201c away from the communication groove 201b, and the arc-shaped embedded groove 203a for limiting the measuring rope 302 can be switched to the straight groove 204a by rotating the push rod 201.

[0040] In use, the angle of the push rod 201 can be adjusted according to the shape of the surface profile of the object, and the push end 203 can be switched to the straight groove 204a through the communication groove 201b. Figure 8 andFigure 9 When the object surface appears bending, the straight slot 204a can be switched to press the measuring rope 302 at the bending point. When the straight slot 204a is used to limit the measuring rope 302, the contact area of the measuring rope 302 is increased, which can improve the fixing effect of the bending point, and the measuring rope 302 is not easy to fall off from the straight slot 204a. Referring to Figure 8 The straight slot 204a is suitable for straight surfaces and bending points. When the bending direction is away from the push rod 201, the straight slot 204a can cover the bending point, and the bending of the measuring rope 302 will not be hindered by the resistance plate 204. Compared with using the arc-shaped embedded slot 203a for limiting, the arc-shaped embedded slot 203a contacts a small point, and the position of the push rod 201 needs to be accurately adjusted to ensure that it is in contact with the bending point. The adjustment difficulty is increased, and the small contact area also causes poor positioning effect. Referring to Figure 9 The straight slot 204a is also suitable for the bending direction close to the push rod 201. Since the measuring rope 302 bends towards the push rod 201, the measuring rope 302 needs to be kept straight during the measurement process to keep the measuring rope 302 adhered to the measured object surface. The measuring rope 302 will have a certain tension, so the force on the bending point will be larger. After the straight slot 204a presses the measuring rope 302, the push rod 201 can be slid to make the straight slot 204a continuously close to the bending point. The straight slot 204a presses the measuring rope 302, and the contact area is large, so the fixing effect is good, and the measuring rope 302 is not easy to separate from the measured object surface, further improving the measurement accuracy.

[0041] Embodiment 2, referring to Figures 1 to 9 The second embodiment of the present application is different from the previous embodiment in that the limiting frame 100 is provided with an upper movable slot 103, and the upper movable slot 103 is slidably provided with an upper positioning member 105.

[0047] The remaining structures are the same as those in Embodiment 1.

[0048] In use, due to the existence of the spring 202 elasticity, and the mutual fitting of the lower bevel 104d and the upper bevel 105d, the spring 202 elasticity will make the upper slide plate 105b and the lower slide plate 104b away from each other, since the upper movable slot 103 is not fitted to the upper positioning member 105, the upper positioning member 105 and the upper movable slot 103 have a large gap, therefore, when the lower baffle 402 and the upper pressing plate 401 do not approach each other to press the lower slide plate 104b and the upper slide plate 105b, the friction force received by the pusher 200 when sliding is small, which is convenient for adjusting the position of the pusher 200, and when measuring the profile of the object, the lower baffle 402 and the upper pressing plate 401 can be made to approach each other by rotating the screw rod 404, the lower baffle 402 extrudes the lower slide plate 104b, the upper pressing plate 401 extrudes the upper slide plate 105b, under the guidance of the lower bevel 104d and the upper bevel 105d, the upper positioning member 105 slides obliquely, the lower limiting member 104 slides vertically, the upper slide plate 105b and the lower slide plate 104b approach each other, until the lower abutting arc surface 104e and the upper abutting arc surface 105e abut against the inner wall of the push rod 201, at this time, the position of the push rod 201 can be fixed, even if the push end 203 does not abut against the measured object, the device can simulate the profile of the surface of the measured object through the fixation of the push rod 201, which is convenient for further measurement and analysis.
