DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will be further described in detail below in conjunction with the accompanying drawings of the specification and the specific embodiments.

[0026] See the attachedFigure 1 to the attached Figure 4 As shown, this embodiment provides a standing children's foot-shaped test tool 100 that is convenient for storage, which includes a sole portion 1 and a first connecting section 2, a second connecting section 3, and a third connecting section 4 that extend upward from the sole portion 1. The third connecting section 4, the second connecting section 3, and the first connecting section 2 are connected in sequence from top to bottom, and the first connecting section 2 is detachably and firmly installed on the upper end surface of the sole portion 1.

[0027] With reference to FIGS. 1 and the attached Figure 2 As shown, in this embodiment, a threaded hole 12 is formed on the upper end surface of the sole portion 1. The bottom end of the first connecting section 2 is formed with a first threaded connecting post 21 that extends vertically downward. An external thread connected to the threaded hole 12 is formed on the outer end surface of the first threaded connecting post 21. The first connecting section 2 can be threadedly and firmly installed on the sole portion 1 through the first threaded connecting post 21.

[0028] Continue to refer to the attached Figure 1 and the attached Figure 2 As shown, an external thread 22 is formed on the outer end surface of the top end of the first connecting section 2, and an internal thread 31 connected to the external thread 22 is formed on the inner wall of the bottom end of the inner cavity of the second connecting section 3. In this way, the first connecting section 2 can be firmly installed at the bottom end of the second connecting section 3 through the external thread 22 at its top end.

[0029] Continue to refer to the attached Figure 1 , the attached Figure 2 and the attached Figure 8 As shown, an external thread 32 is formed on the outer end surface of the top end of the second connecting section 3, and an internal thread 41 connected to the external thread 32 is formed on the inner wall of the bottom end of the inner cavity of the third connecting section 4. In this way, the second connecting section 3 can be firmly installed at the bottom end of the third connecting section 4 through the external thread 32 at its top end. At the same time, in order to facilitate folding and retracting the standing children's foot-shaped test tool 100, the third connecting section 4 is detachably and fixedly installed on the sole portion 1. A second threaded connecting post 42 that extends vertically downward is formed at the bottom end of the third connecting section 4. Similarly, an external thread is formed on the outer surface of the second threaded connecting post 42. In this way, the third connecting section 4 can be fixedly installed in the threaded hole 12 on the upper end surface of the sole portion 1 through the second threaded connecting post 42 at its bottom.

[0030] Refer to the attached Figure 1 to the attached Figure 4 As shown, in this embodiment, the outer diameter of the third connecting section 4 is larger than the outer diameter of the first connecting section 2. The second connecting section 3 is connected and installed between the bottom end of the third connecting section 4 and the top end of the first connecting section 2. And the second connecting section 3 is formed with a first accommodating cavity for vertically inserting the first connecting section 2, and the third connecting section 4 is formed with a second accommodating cavity for vertically inserting the second connecting section 3.

[0031] Referring to the attached Figure 3 drawing and the attached Figure 4 drawing, when folding and retracting, vertically insert the bottom end of the first connecting section 2 into the first receiving cavity of the second connecting section 3. After the insertion of the first connecting section 2 into the first receiving cavity of the second connecting section 3 is completed, insert the second connecting section 3 with the inserted first connecting section 2 into the second receiving cavity of the third connecting section 4. After the insertion of the second connecting section 3 into the second receiving cavity is completed, install the third connecting section 4 onto the threaded hole 12 of the foot bottom 1 through the second threaded connecting post 42 at its bottom end. In this way, the folding and retracting state of the entire standing children's foot-shaped test device 100 is completed. At this time, the top surface of the second connecting section 3 is at the uppermost position (since the length dimension of the second connecting section 3 is slightly larger than the length dimension of the third connecting section 4, the length dimension of the second connecting section 3 is 200 mm, and the length dimension of the third connecting section 4 is 170 mm). For the standing children's foot-shaped test device 100 in the folding and retracting state, its external dimension is shortened, that is, approximately reduced to the external dimension of a single third connecting section 4, and the occupied space dimension is reduced, which is convenient for storage and carrying.

[0032] Combined with referring to the attached Figure 3 drawing, Figure 4 and the attached Figure 6 drawing, in order to prevent the standing children's foot-shaped test device 100 after folding and retracting from being prone to shaking and falling, the standing children's foot-shaped test device 100 in this embodiment further includes a strap assembly 5. Use the strap assembly 5 to tie the standing children's foot-shaped test device 100 in the folding and retracting state together from top to bottom to prevent the components from falling off.

[0033] Specifically, in this embodiment, the strap assembly 5 includes an elastic strap 51 with openings at both opposite ends, a slot 52 provided at the open end of the elastic strap 51, and an elastic snap plug provided at the other open end of the elastic strap 51. The bottom end of the elastic strap 51 is fixedly installed at the bottom end of the foot bottom 1.

[0034] Referring to the attached Figure 3 drawing to Figure 6 the attached drawing, when tying, stretch the slot 52 and the elastic snap plug upward from both sides at the bottom end of the foot bottom 1, stretch the slot 52 and the elastic snap plug to the top surface of the third connecting section 4, and insert the elastic snap plug into the slot 52, so as to realize the bundling of the standing children's foot-shaped test device 100 in the folding and retracting state. When it needs to be loosened, by pressing the elastic snap plug in the central direction, the elastic snap plug pops out from the slot 52, and the bundling of the elastic strap 51 on the standing children's foot-shaped test device 100 in the folding and retracting state can be released. It should be noted that the slot 52 and the elastic pressing plug 53 at both ends of the elastic strap 51 in this embodiment can adopt the elastic pressing buckle structure commonly used on the market for schoolbags.

[0035] With reference to the attached Figure 3 and the attached Figure 7 As shown, in order to prevent the elastic band 51 from slipping on the top surface of the second connecting section 3, a pair of notches 33 are formed in opposite directions at the top of the second connecting section 3. When the elastic band 51 passes through the top surface of the second connecting section 3, the elastic band 51 passes through the pair of notches 33, so that the elastic band 51 will not slide left and right on the top surface of the second connecting section 3.

[0036] Refer to the attached Figure 6 As shown, a groove 11 for accommodating the elastic band 51 to pass through is formed at the bottom end of the sole 1. At the same time, a baffle 13 for restricting the movement of the socket 52 or the elastic snap plug to the other side is formed at the bottom end surface of the groove 11 at the bottom of the sole 1, that is, the gap between the baffle 13 and the groove 11 is smaller than the thickness dimension of the plug or the elastic snap, so that the socket 52 cannot move to the other side through the groove 11, and the elastic snap plug cannot move to the side of the socket 52 through the groove 11 either.

[0037] To better understand the standing children's foot shape test device 100 in this embodiment, the working principle thereof will be briefly described below:

[0038] During daily storage or transportation, the first connecting section 2 can be conveniently inserted into the first accommodation cavity of the second connecting section 3, and then the second connecting section 3 can be inserted into the second accommodation cavity of the third connecting section 4, and the third connecting section 4 can be directly fixed on the sole 1. In this way, the first connecting section 2, the second connecting section 3, and the third connecting section 4 are inserted and sleeved together correspondingly to form a folded state with an approximate outer shape length of the third connecting section 4, shortening the length of the entire standing children's foot shape test device 100 and facilitating storage and carrying; and when normal use is required, only the first connecting section 2, the second connecting section 3, and the third connecting section 4 need to be taken out and assembled in sequence, that is, the bottom end of the first connecting section 2 is firmly installed on the upper end surface of the sole 1, the top end of the first connecting section 2 is fixedly installed at the bottom end of the second connecting section 3, and the top end of the second connecting section 3 is fixedly installed at the bottom end of the third connecting section 4. The entire assembly process is convenient and fast.
