[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and do not constitute a limitation to the present invention.
[0023] The directional terms or positional relationships such as "left" and "right" described in the embodiment are based on the drawings in the specification of the utility model. Figure 3 The orientation relationship is only for the convenience of describing the present invention and simplifying the description. It does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the content protected by the present invention.
[0024] Example 1
[0025] like Figures 1 to 5 As shown, this embodiment includes a bracket 2 and a marking pen 1 rotatably arranged on the bracket 2, the axial direction of the marking pen 1 is arranged along the vertical direction, and the vertical direction in this embodiment refers to the up and down directions; an opening is provided on the bracket 2 for allowing the marking pen 1 to fit with the edge of the foot, and a support member is fixed at the end of the bracket 2 away from the foot to prevent the body of the marking pen 1 from tilting in a direction away from the foot. The tip of the marking pen 1, the bottom edge of the bracket 2 and the bottom edge of the support member are on the same horizontal plane. In this embodiment, the horizontal plane is perpendicular to the vertical direction and refers to the direction of the paper surface.
[0026] 1. Bracket 2;
[0027] like Figure 1 As shown, the bracket 2 includes a bearing 21, a first leg 22, and a second leg 23. The bearing 21 is fixed to the top of the first leg 22 and the second leg 23. Specifically, the first leg 22 and the second leg 23 are fixedly connected to the outer ring of the bearing 21. The first leg 22 and the second leg 23 are symmetrically arranged with respect to the bearing 21. In other words, in the projection on the paper, as shown in FIG. Figure 4 As shown, the line connecting the first leg 22 and the second leg 23 forms 180 degrees.
[0028] The first leg 22 and the second leg 23 have the same structure. The first leg 22 is used as an example. Figure 1 As shown, the first leg 22 includes an inclined rod 221 fixedly connected to the outer ring of the bearing 21 and a crossbar 222 fixed to the bottom end of the inclined rod 221. The crossbar 222 contacts the paper surface to enable the device to be placed on the paper. The structure of the second leg 23 is the same as that of the first leg 22 and will not be repeated here.
[0029] In this embodiment, the marker pen 1 is located between the first leg 22 and the second leg 23. The bracket 2 is provided with an opening for the marker pen 1 to fit with the edge of the foot. The opening here refers to the right side of the first leg 22 and the second leg 23 being open. Figure 3 、 4 , make the outer contour of the drawing pen 1 fit with the edge of the foot so that the drawing pen 1 can move along the edge of the foot to complete the line drawing, see Figure 5 .
[0030] 2. Line drawing pen 1;
[0031] like Figure 1-3 As shown, the marker pen 1 vertically passes through the inner ring of the bearing 21, and the outer contour of the marker pen 1 is adapted to the shape of the inner ring of the bearing 21. Adaptation here means that the outer contour of the marker pen 1 is the same as the shape of the inner ring of the bearing 21. In this embodiment, the inner ring of the bearing 21 and the outer contour of the marker pen 1 are both circular.
[0032] The marker pen 1 is fixedly sleeved with the inner ring of the bearing 21. The fixing sleeve method can be any of the following methods:
[0033] Method 1: The size of the marker pen 1 is slightly larger than the inner diameter of the bearing 21, and the marker pen 1 and the inner ring of the bearing 21 have an interference fit;
[0034] Method 1: The marker pen 1 is fixed to the inner wall of the bearing 21 by adhesive.
[0035] The marker pen 1 of this embodiment is a pencil with a circular outer contour in the prior art. Of course, any pen in the prior art, such as a signature pen, can also be selected as long as it can be fixed to the inner ring of the bearing 21.
[0036] In this embodiment, the marker pen 1 is fixedly connected to the inner ring of the bearing 21, so that the marker pen 1 and the bracket 2 can rotate relative to each other. Of course, any other structure capable of achieving rotational connection in the prior art can also be used.
[0037] 3. Support parts;
[0038] like Figure 2 、 3 As shown, in this embodiment, the support member is the third leg 3. The structure of the third leg 3 is identical to that of the first leg 22 and will not be further described here. The diagonal rod in the third leg 3 is fixed to the outer ring of the bearing 21. A crossbar is fixed to the bottom end of the diagonal rod. The crossbar contacts the paper surface, thus ensuring that the device can be placed stably on the paper.
[0039] The third leg 3 is provided between the first leg 22 and the second leg 23. Specifically, Figure 2As shown, in the projection of the vertical plane where the first leg 22 and the second leg 23 are located, the third leg 3 is located in the middle of the first leg 22 and the second leg 23. The tip of the marker 1, the bottom edge of the bracket 2 and the bottom edge of the support are on the same horizontal plane, that is, the tip of the marker 1, the crossbar 222 of the first leg 22, the crossbar 223 and the crossbar 3 of the third leg are on the same horizontal plane, ensuring that the tip of the marker 1 can contact the paper surface and draw lines smoothly. When drawing lines, the third leg 3 can prevent the pen body of the marker 1 from moving along the paper surface. Figure 3 The direction of the middle arrow is tilted to the left (the body of the liner pen 1 is tilted to the left, which is equivalent to the tip of the liner pen 1 being tilted to the right), which solves the problem of smaller measurement data.
[0040] The support member can also be replaced with any structure in the prior art, and the fixed position of the support member can also be selected at any position between the first leg 22 and the second leg 23, as long as it can support the bracket 2 and prevent the bracket 2 and the drawing pen 1 from tilting to the left.
[0041] When using this embodiment, see Figure 5 Place the device on paper, with the first leg 22, second leg 23, and outer contour of the marker 1 aligned with the edge of the foot, and the third leg 3 positioned away from the foot. Move the marker 1 so that it draws a line along the edge of the foot. During this movement, as long as the first leg 22, second leg 23, and third leg 3 are all in contact with the paper, the marker 1 remains perpendicular to the paper, ensuring accurate line drawing and preventing under-measurement. Even if the first leg 22, second leg 23, and third leg 3 are not in contact with the paper at the same time, the support provided by the third leg 3 ensures that the marker 1 does not tilt away from the foot, preventing the customer from being unable to wear the shoes due to under-measurement.
[0042] Example 2
[0043] The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 6 As shown, in this embodiment, the inner ring of the bearing 21 and the outer contour of the marker are both hexagonal. Figure 6 The middle line pen is not shown; other than this, the structures and arrangement positions of the first leg 22, the second leg 23, and the third leg 3 are exactly the same as those in Example 1 and will not be elaborated in detail in this embodiment.
[0044] The usage process of this embodiment refers to Example 1.
[0045] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents.
