Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in FIGS. 1 to 4, the preferred embodiment of the present invention is shown.

The portable chair support in this embodiment includes a chair support and four leg tubes 2, the chair support includes four connecting seats 1, a seat tube 4 is inserted on the upper side of each connecting seat 1, and a support tube 3 is inserted between two adjacent connecting seats 1 (see fig. 2). The foot tubes 2 correspond to the connecting seats 1 one by one and are detachably connected. The seat support has a high position state and a low position state, and in the high position state, each foot tube 2 is vertically constrained on the corresponding connecting seat 1 (see figure 1); in the low position, each leg tube 2 is constrained on the corresponding connecting seat 1 along the horizontal direction (see fig. 2). The "vertical direction" is not limited to a vertical direction, and allows the leg tube 2 to be tilted from the vertical direction. In the present embodiment, each leg tube 2 is gradually separated from the center of the seat holder from the top to the bottom when the seat holder is in the high position, so that the center of gravity of the portable seat holder can be lowered, and the friction force between each leg tube 2 and the placement surface of the portable seat holder can be increased. The placing surface of the portable chair support can be the ground or the table top of an object.

In the portable chair support in this embodiment, the portable chair support makes the chair support have a high-order state and a low-order state through restricting each foot pipe 2 on the connecting seat 1 that corresponds along vertical or along the horizontal direction to the realization is to the altitude mixture control of portable chair support, makes this portable chair support can adapt to different height demands, and the commonality is stronger.

As shown in fig. 4, the four connecting seats 1 are divided into a first group and a second group, the first group has two first connecting seats 1a arranged at intervals, the second group has two second connecting seats 1b arranged at intervals, and the second connecting seats 1b are arranged in one-to-one correspondence with the first connecting seats 1 a. The four support tubes 3 are divided into a group a and a group B, the group a has two first support tubes 31, and the first support tubes 31 are detachably provided between each first connecting seat 1a and the corresponding second connecting seat 1B; the group B has two second support tubes 32, each of the second support tubes 32 is disposed between two first connection seats 1a and between two second connection seats 1B, and both ends of each of the second support tubes 32 are fixed to the corresponding connection seat 1 by a fastener such as a screw, so that the two first support tubes 31 can be detached to reduce the size of the portable stand when the portable stand is not used. Each first supporting tube 31 is inside all to have held second elasticity rope 6, and this second elasticity rope 6's one end is connected with seat pipe 4 of installing on the first connecting seat 1a that corresponds, and the other end of second elasticity rope 6 is connected with seat pipe 4 of installing on the second connecting seat 1b that corresponds to can make first supporting tube 31 dismantle the back and be difficult to lose.

As shown in fig. 4, each seat tube 4 is detachably connected to the corresponding connecting holder 1, and each seat tube 4 can be separated from the corresponding connecting holder 1 when the portable chair support is not used. The four seat tubes are divided into two front seat tubes 41 and two rear seat tubes 42, wherein the two rear seat tubes 42 are both telescopic tubes, so that the volume of the portable chair support after being folded can be further reduced. Specifically, each of the rear seat tubes 42 includes an outer tube 421 and an inner tube 422 slidably disposed inside the outer tube 421, a locking hole (not shown) is disposed on the outer tube 421, and an elastic locking pin (not shown) is disposed on the inner tube 421, and the elastic locking pin (not shown) can be locked in the locking hole (not shown), so as to lock a relative position between the outer tube 421 and the inner tube 422, and further lock a length of each of the rear seat tubes 42.

Each connecting seat 1 is provided with a first inserting hole 11 and a first inserting groove 12, the first inserting hole 11 inclines downwards (see fig. 3), the first inserting groove 12 faces to the horizontal direction (see fig. 1), and each foot tube 2 is inserted into the corresponding first inserting hole 11 (see fig. 1) in the high-position state of the seat support; in the low position state of the seat support, each leg tube 2 is inserted into the corresponding first slot 11 (see fig. 2), so that each leg tube 2 and the corresponding connecting seat 1 can be conveniently disassembled or assembled. Each connecting base 1 has a first side 101 and a second side 102 opposite to each other, the first side 101 of each connecting base 1 is connected to the end of the corresponding first supporting tube 31, and each first slot 11 is disposed on the second side 102 of the corresponding connecting base 1 (see fig. 1), so that each pin tube 2 can be inserted into the corresponding first slot 11. Each inside elasticity rope 5 that all is equipped with of foot pipe 2, and all open the breach 111 (see fig. 4) that the first elasticity rope 5 that supplies to correspond passed on the cell wall of each first slot 11 to make each foot pipe 2 be difficult to lose after separating with the connecting seat 1 that corresponds.

As shown in fig. 1 and 3, the opening directions of the first slots 11 on the two first connecting seats 1a are opposite to each other, and the opening directions of the first slots 11 on the two second connecting seats 1b are opposite to each other, so that the leg tubes 2 of the two first connecting seats 1a are overlapped with the second support tube 32 arranged between the two first connecting seats 1a more, and the leg tubes 2 of the two second connecting seats 1b are overlapped with the second support tube 32 arranged between the two second connecting seats 1b more, when the seat support is in a low position, thereby further reducing the volume of the portable seat support after being folded. The first slots 11 on the two first connecting seats 1a are arranged in a staggered manner in the height direction, and the first slots 11 on the two second connecting seats 1b are arranged in a staggered manner in the height direction. Therefore, when the seat support is in a low position state, the leg tubes 2 on the two first connecting seats 1a and the leg tubes 2 on the two second connecting seats 1b cannot interfere with each other.

The bottom of each connecting seat 1 is provided with a trapezoidal convex block 13, and the cross section of the trapezoidal convex block 13 is gradually reduced from bottom to top (see fig. 3), so that the contact area between the trapezoidal convex block 13 and the placing surface of the portable chair support can be increased. The bottom surface of each trapezoidal convex block 13 is provided with an anti-skid convex point 131 (see fig. 3), so that the friction coefficient of the bottom surface of each trapezoidal convex block 13 can be increased, the friction force between the portable seat support and the placing surface when the seat support is in a low position state is further increased, and the anti-skid performance of the portable seat support is better when the seat support is in the low position state.

A portable chair in this embodiment comprises a cloth (not shown) detachably attached to the above-mentioned portable chair support and connected to the seat tube 4.
