Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a but to hinge structure complicacy among the prior art, spare part is too much and lead to the foot rest to easily rock when supporting, supports unstable shortcoming, the utility model provides a collapsible foot rest, the structure is shown as figure 1, including stabilizer blade 1, connecting piece 2 and screw rod 3.

The structure of the supporting foot 1 is shown in fig. 2, and comprises vertical supporting arms 11 located at the left and right sides, and a horizontal connecting rod 12 connecting the vertical supporting arms 11 at the two sides, wherein a first through hole 121 with threads is arranged on the horizontal connecting rod 12. The feet 1 are used to connect the connectors 2 and can rotate in the connectors 2 to enable the foot rest to be unfolded and folded, while the feet 1 contact the ground to provide vertical support.

The connecting member 2 is constructed as shown in fig. 3 and 4, and includes horizontal connecting blocks 21 at upper and lower ends, and a tubular passage 22 between the horizontal connecting blocks 21, the horizontal connecting blocks 21 being integrally formed with the tubular passage 22. The horizontal connecting block 21 is provided with a mounting hole 211 for connecting the soft body structure 4. A second through hole 221 for rotationally clamping the screw rod 3 is formed in the tubular channel 22, clamping holes are formed in the upper end and the lower end of the second through hole 221, a channel hole is formed in the middle of the second through hole, the clamping hole in the upper end of the second through hole 221 is a clamping hole when the foot rest is folded, and the clamping hole in the lower end of the second through hole is a clamping hole when the foot rest is unfolded; the upper end and the lower end of the clamping hole are circular through holes, the channel hole is an equal-width hole communicated with the upper end and the lower end of the clamping hole, and the diameter of the upper end and the lower end of the clamping hole is larger than that of the channel hole. The horizontal connecting rod 12 of the supporting leg 1 penetrates through the tubular passage of the connecting piece 2, and the first through hole 212 and the second through hole 221 of the horizontal connecting rod 12 are communicated; the horizontal connecting block 21 of the connecting piece 2 is in screw connection with the soft body structure 4 through the mounting hole 211; the screw 3 is located in the second through hole 221 of the connecting member 2 and is threadedly coupled with the first through hole 121 of the horizontal link 12 of the leg 1.

The structure of the screw rod 3 is as shown in fig. 5, and comprises a nut 31 at the upper end, a clamping column 32 located at the middle part and clamped with the second through hole 221, and a stud 33 located at the lower end and matched with the thread of the first through hole 121; the nut 31, the engaging post 32, and the stud 33 are integrally formed.

The connecting structure of the connecting piece 2 and the soft body structure 4 is shown in fig. 6, and the soft body structure 4 can be a cushion filled with sponge, fabric and springs, and can also be common household articles, such as chairs, sofas, beds and the like. Because the supporting foot 1 penetrates the connecting piece 2, the folding and unfolding of the foot rest are completed by the supporting foot 1 rotating in the tubular channel 22 of the connecting piece 2, and in order to reduce the resistance of the supporting foot 1 when the tubular channel 22 rotates, a rubber pipe is arranged at the position where the horizontal connecting rod 12 of the supporting foot 1 contacts the tubular channel 22, and the length of the rubber pipe is consistent with that of the tubular channel 22.

As shown in fig. 7, when the tripod is unfolded, the screw 3 is first twisted to prevent the engaging column 32 from engaging with the second through hole 221, the supporting leg 1 is rotated to a corresponding position, and then the screw 3 is screwed in to engage the engaging column 32 with the second through hole 221, so that the tripod is fixed. The folding process of the foot rest is the same as the unfolding process of the foot rest, and the description is not repeated. In an embodiment, the central angle corresponding to the centers of the two engaging holes of the second through hole 221 is 90 degrees, that is, the rotation angle of the stand is 90 degrees. The two folding foot stands are used as supporting frames to be connected with the bottom surface of the soft structure 4 and are folded on the bottom surface of the soft structure 4.
