Detailed Description

In order to further explain the technical scheme of the utility model, the following is explained in detail through specific examples.

The utility model relates to a connecting seat, as shown in figures 1-11, comprising a seat main body 1, wherein the seat main body 1 comprises a bottom side wall 11 for accommodating the lower part of a bottom cover 21 and a connecting edge 12 positioned on the outer ring of the bottom side wall 11; the bottom accommodating side wall 11 forms an accommodating space 13 accommodating the bottom extending portion 211 of the bottom cover 21; the bottom side wall 11 includes a main side wall 111 and a corresponding wall 112 corresponding to the string passing portion 212 of the bottom cover 21, the main side wall 111 having an adjacent wall 1111 adjacent to the corresponding wall 112, at least an upper end of the adjacent wall 1111 of the main side wall 111 being lower than the string passing hole of the bottom cover 21. In the practical use process of the utility model, the connecting seat is matched with the bottom cover 21, for example, after the connecting seat is connected with articles such as shoes, the bottom cover 21 can be directly buckled on the connecting seat. Specifically, the bottom extending portion 211 of the bottom cover 21 extends into the accommodating space 13 of the connection seat and is buckled together through a buckling structure, the rope passing portion 212 of the bottom cover 21 corresponds to the corresponding portion of the connection seat, and the rope is tightened or loosened by the winding shaft 3 through the rope passing portion 212 above the corresponding portion. Because the upper end of the main side wall 111 is lower than the height of the rope hole of the bottom cover 21, the corresponding wall 112 is not lower than the height of the adjacent wall 1111, a gap for passing the rope is not formed at the corresponding wall 112, the height and bending strength of the bottom side wall 11 at the position mainly subject to the pulling force of the rope are ensured, the bottom cover 21 is not easy to deform and is tripped, the rope hole lifting effect is realized to a certain extent, the height of the main side wall 111 is not excessively increased, the friction force to the connecting edge 12 and the surfaces of articles such as shoes or the rope is not separated from the connecting edge 12 and the surfaces of the articles such as shoes, the rope slides smoothly, the knob 4 rotates smoothly and the whole height of the rope turnbuckle is not higher.

In another embodiment, the upper end of the corresponding wall 112 is flush with the upper end of the adjacent wall 1111. This structure makes the corresponding wall 112 and the adjacent wall 1111 equal in height and neat, is less prone to stress concentration, ensures strength at the corresponding wall 112 and the adjacent wall 1111, and is less prone to hand scraping when the operator rotates the knob 4, and is smoother.

In another embodiment, the upper end of the corresponding wall 112 is higher than the upper end of the main side wall 111. This structure can ensure a sufficient space and strength of the first catching step 141 when the first catching step 141 is formed on the two corresponding walls 112.

In another embodiment, the height of the upper end of the corresponding wall 112 is lower than that of the upper end of the adjacent wall 1111 and forms a locking notch 1121 for accommodating the bottom wall 21214 of the nozzle, and the depth of the locking notch is smaller than the thickness of the bottom wall 21214 of the nozzle. This structure ensures that the rope is integrally higher than the clamping notch 1121 of the corresponding wall 112 when passing through the rope hole, at least not lower than the height of the adjacent wall 1111, and ensures that the rope is lifted thereat, and the bottom-containing side wall 11 has sufficient height and integrity to generate sufficient omnibearing limiting strength for the bottom-extending portion 211 of the bottom cover 21.

In another embodiment, the bottom side wall 11 includes two corresponding walls 112 corresponding to the two-way string portions 212 of the bottom cover 21, respectively. This configuration allows the two corresponding walls 112 to accommodate a cord turnbuckle that wraps around two cords.

The structure can make the two corresponding walls 112 divide the main side wall 111 into two areas, so that the first fastening step 141 and the second fastening step 142 are arranged on the elastic wall 1112 and the main body wall 1113 respectively, and the connecting seat and the bottom cover 21 are fastened and positioned in two directions, thereby ensuring firmness.

In another embodiment, the length of the resilient wall 1112 is less than the length of the body wall 1113.

In another embodiment, a gap 115 is formed between the elastic wall 1112 and the two corresponding walls 112. The main body wall 1113 may mainly provide a limiting strength to the bottom cover 21, and the elastic wall 1112 may be elastically deformed to facilitate the first clamping block 2131 to be clamped in, and the gap 115 may be used to facilitate the elastic wall 1112 to deform relative to the main body wall 1113. If the second clamping block 2132 can be clamped into the second clamping step 142, then the first clamping block 2131 is pressed to be clamped into the first clamping step 141 in a deformation form by pressing the elastic wall 1112, and the elastic wall 1112 can keep the clamping connection between the first clamping step 141 and the first clamping block 2131 after the restoration.

In another embodiment, the gap 115 has a width of 0.1-3mm. The gap 115 of this size facilitates the inner and outer deformation of the elastic wall 1112 relative to the body wall 1113 while facilitating the demolding.

In another embodiment, the gap 115 has a width of 0.2-1.5mm. The gap 115 of this size can ensure the elastic wall 1112 is deformed inward and outward with respect to the main body wall 1113 while facilitating the demolding molding.

The recess 1122 allows the corresponding portion of the outer side of the bottom cover 21 to extend into and cooperate with each other to limit the position, so as to prevent the connecting seat and the bottom cover 21 from rotating relatively.

In another embodiment, the inner side walls of the resilient wall 1112 protrude further inward than the recess 1122. This structure ensures that the bottom cover 21 is blocked from rotating when the bottom cover 21 is engaged with the inner side of the corresponding wall 112.

In another embodiment, the recess 1122 forms a detent space for receiving the mouth bottom wall 21214. This structure ensures that the corresponding parts on the outer side of the bottom cover 21 extend into and cooperate with each other to limit the positions, and prevents the connecting seat and the bottom cover 21 from rotating relatively.

In another embodiment, the connecting edge 12 is arranged horizontally or at least extends gradually downwards from inside to outside. This configuration facilitates adaptation to the different shapes of the connecting surface of the article such as a shoe.
