Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

As shown in fig. 1 to 8, the standpipe holding assembly of the embodiment of the present utility model includes a folding seat 1, a standpipe 2, a sleeve 3 and a fastener 4.

The folding seat 1 is provided with an inner hole 13, for example, as shown in fig. 1, the folding seat 1 may comprise a first seat 11 and a second seat 12, wherein the first seat 11 may be pivotally mounted above the second seat 12. The inner hole 13 may be provided on the second seat 12, and the inner hole 13 may extend along an axial direction (up-down direction) of the second seat 12. As shown in fig. 1 to 3, the standpipe 2 may be a circular tube, the inner hole 13 may be a circular hole, and a top end portion of the standpipe 2 may be inserted into the inner hole 13 of the second seat 12.

It should be noted that, in this embodiment, the second seat 12 is used to connect with the vertical tube 2, the first seat 11 may connect with the vertical tube below the handlebar of the scooter, and the folding and storage functions of the scooter may be realized by means of the relative rotation adjustment of the first seat 11 and the second seat 12.

The sleeve 3 can be fitted in the annular space formed by the standpipe 2 and the second seat 12, i.e. the sleeve 3 is arranged in the inner bore 13 and around the periphery of the standpipe 2. As shown in fig. 4, the sleeve 3 may include an inner ring 33 and an outer ring 34, each of the inner ring 33 and the outer ring 34 may be circular, and each of the inner ring 33 and the outer ring 34 is sleeved on the outer circumferential side of the standpipe 2, wherein the inner ring 33 may be provided in the outer ring 34.

As shown in fig. 6, the outer peripheral wall of the inner ring 33 and the inner peripheral wall of the outer ring 34 may each be provided with a slope, and the wedging fit between the inner ring 33 and the outer ring 34 is achieved by the fitting engagement of the slopes, whereby, when one of the inner ring 33 and the outer ring 34 receives an axial (up-down) force, displacement in the radial direction (horizontal direction) of the sleeve 3 may be generated between the inner ring 33 and the outer ring 34 under the guidance of the slope, for example, the outer ring 34 has a tendency to expand outward under the action of the inner ring 33, and the inner ring 33 has a tendency to pinch inward. Thereby, the thickness dimension of the inner ring 33 and the outer ring 34 (the overall thickness dimension of the set 3 in the radial direction) can be changed, that is, adjustment of the thickness dimension of the set 3 (fine adjustment by deformation of the inner ring 33 and the outer ring 34) can be achieved.

It should be noted that, when the squeezing action between the inner ring 33 and the outer ring 34 becomes larger, the thickness dimension of the sleeve 3 tends to increase, and by virtue of the internal expansion action of the sleeve 3, the sleeve 3 can prop against the hole wall of the inner hole 13 of the standpipe 2 and the second seat 12, so that the frictional self-locking fixation of the standpipe 2 and the second seat 12 can be realized.

The fasteners 4 are mounted to the standpipe 2 and rest against either the inner ring 33 or the outer ring 34, and the axial position of the fasteners 4 along the standpipe 2 is adjustable so that the amount of force applied by the fasteners 4 to the set 3 is adjustable. For example, as shown in fig. 3 and 6, the fastener 4 may be a bolt, the top of the standpipe 2 may be provided with a threaded hole extending in the axial direction of the standpipe 2, the fastener 4 may be threadedly fitted into the threaded hole, and the end (bolt head) of the fastener 4 may be stopped against the inner ring 33.

When the vertical tube type self-locking device is used, the relative positions of the fastener 4 and the vertical tube 2 can be adjusted by screwing the fastener 4, so that the adjustment of the acting force applied to the inner ring 33 by the fastener 4 can be realized, the adjustment of the wedge force between the inner ring 33 and the outer ring 34 and the adjustment of the thickness dimension of the sleeve group 3 can be realized, and finally the tight-holding self-locking fixation of the vertical tube 2 and the folding seat 1 can be realized.

The standpipe enclasping component realizes locking and fixing of the standpipe 2 in a self-locking friction enclasping mode, has large locking force and good locking stability compared with a mode of locking by a screw of a hoop device, and further improves use safety.

Secondly, the sleeve group 3, the fastening piece 4 and the like for locking can be arranged in the folding seat 1 (the second seat 12), so that the hidden design of the locking component is realized, and the problems that false touch and poor appearance are easily caused when the locking device is adopted to fix and is exposed are avoided.

In addition, the vertical pipe enclasping assembly can complete enclasping self-locking only through the sleeve group 3 and the fastener 4, parts are fewer, the requirement on the matching precision of the parts is lower, and the production and processing cost is reduced.

In some embodiments, there are two sets 3, the two sets 3 are a first set 31 and a second set 32, respectively, the first set 31 is disposed at one end of the inner hole 13, the second set 32 is disposed at the other end of the inner hole 13, and the first set 31 and the second set 32 are both used to prop between the standpipe 2 and the folding seat 1.

For example, as shown in fig. 1 and 3, both the first set 31 and the second set 32 can be nested on the outer peripheral side of the standpipe 2, wherein the first set 31 can be located above the second set 32 and spaced from the second set 32. When the standpipe 2 is fitted in the bore 13 of the folding seat 1, the first set 31 may be located at the top end aperture of the bore 13 and the second set 32 may be located at the bottom end aperture of the bore 13.

When the fastener 4 is screwed, the inner ring 33 and the outer ring 34 of the first set 31 and the inner ring 33 and the outer ring 34 of the second set 32 can be extruded under the action of the fastener 4, and the first set 31 and the second set 32 can prop up between the vertical pipe 2 and the hole wall of the inner hole 13 of the folding seat 1, so that the vertical pipe 2 and the upper and lower parts of the folding seat 1 are tightly held and self-locked and fixed, the fixing effect is improved, and the fixing stability is ensured.

In some embodiments, the bore 13 includes a first bore section 131, a second bore section 132, and a third bore section 133, the second bore section 132 being connected between the first bore section 131 and the third bore section 133, the first bore section 131 having a larger bore diameter than the second bore section 132, the first set 31 being assembled to the first bore section 131, and the second set 32 being assembled to the third bore section 133.

For example, as shown in fig. 8, along the extending direction of the inner bore 13, the inner bore 13 may be divided into a first bore section 131, a second bore section 132, and a third bore section 133 according to the difference in bore diameter, wherein the first bore section 131 may be located above the second bore section 132, and the third bore section 133 may be located below the second bore section 132. The radial dimension of the first bore section 131 is larger than the second bore section 132 and the radial dimension of the third bore section 133 is also larger than the second bore section 132.

Thus, the first hole segment 131 may provide an assembly space for the first set 31 and the second hole segment 132 may provide an assembly space for the second set 32, facilitating assembly of the first set 31 and the second set 32. Secondly, the step surface between the first hole section 131 and the second hole section 132 can be stopped against the inner ring 33 or the outer ring 34 of the first set 31, thereby playing a limiting effect on the bottom side of the first set 31; the stepped surface between the third bore section 133 and the second bore section 132 may also abut the inner ring 33 or the outer ring 34 of the second set 32, thereby providing a stop effect on the top side of the second set 32.

It should be noted that the second seat 12 of the folding seat 1 and the head tube assembly 6 may be clamped and fixed between the fastener 4 and the fixing seat 5, the first set 31 in the second seat 12 may be clamped between the end of the fastener 4 and the second seat 12, and the second set 32 in the second seat 12 may be clamped between the second seat 12 and the head tube assembly 6. Thus, when screwing down the fastener 4, the distance between the fastener 4 and the fixing base 5 is shortened, and the first set 31, the second base 12, the second set 32, and the head pipe assembly 6 can be clamped, so that adjustment of the applied axial forces of the first set 31 and the second set 32 can be simultaneously achieved.
