[0033] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown.

[0034] like Figures 1 to 5As shown, a folding chair 10 that is easy to carry includes a support component 100 and a load-bearing component 200. The support component 100 includes two folding frames 110. The folding frames 110 include a first leg 111, a second leg 112 and a pin 113. The pin 113 is sequentially passed through the middle of the first leg 111 and the middle of the second leg 112, so that the first leg 111 and the second leg 112 can rotate relative to the pin 113, so that the folding frame 110 is in a closed state or an open state. The load-bearing component 200 includes a tie strip 210, a chair cloth 220 and two cross beams 230. The two ends of the chair cloth 220 are respectively connected to the two cross beams 230. One end of the tie strip 210 is set on one end of the chair cloth 220. The other end of 210 is detachably bonded to the other end of the chair cloth 220; when the two folding frames 110 are in the open state, and the two ends of one of the beams 230 are respectively inserted into the ends on the same side of the two first legs 111, and the two ends of the other beam 230 are respectively inserted into the ends on the same side of the two second legs 112, the chair is in the open state; when the two folding frames 110 are in the closed state, and each beam 230 is pulled out from each first leg 111 and each second leg 112, and the two folding frames 110 and the two beams 230 are put together, the chair cloth 220 and the binding strip 210 are connected end to end in sequence and wrapped around the two folding frames 110 and the outside of the two beams 230 to make the chair in the folded state.

[0035] It should be noted that the portable folding chair 10 of the present application has two holding states, one of which is an open state, which is also a normal use state; the other is a folded state, which is a storage and non-usable state. Specifically, the two folding frames 110 have the same structure, and both folding frames 110 are composed of a first leg 111, a second leg 112 and a pin 113. Specifically, the pin 113 passes through the first leg 111 and the second leg 112 respectively, so that the first leg 111 and the second leg 112 can rotate relative to the pin 113. For example, the pin 113 can be a rivet, so as to ensure that the first leg 111 and the second leg 112 can stably rotate relative to the pin 113 without separating. When the first leg 111 and the second leg 112 are aligned with each other, the folding frame 110 is in a closed state. When the first leg 111 and the second leg 112 are intertwined to form an "X" shape, the folding frame 110 is now in an open state. Furthermore, the two ends of the chair cloth 220 are respectively connected to the two crossbeams 230. For example, the ends of the chair cloth 220 are wrapped around the crossbeams 230 and then sewn together, so that the chair cloth 220 is sleeved on the crossbeams 230, so that the chair cloth 220 can slide along the axial direction of the crossbeams 230 to adjust its position. In this way, when both folding frames 110 are in an open state, the two ends of one of the crossbeams 230 are respectively inserted into the first legs 111 of the two folding frames 110, and the two ends of the other crossbeam 230 are respectively inserted into the second legs 112 of the two folding frames 110. In this way, when the chair is placed on the ground, the first leg 111 and the second leg 112 tend to open at a larger angle, but since the first leg 111 and the second leg 112 are connected and fixed by two cross beams 230, and the two cross beams 230 are pulled by the chair cloth 220, the chair cloth 220 is taut at this time, so the user can sit comfortably on the chair cloth 220. Furthermore, after both crossbars 230 are pulled out from the first leg 111 and the second leg 112, the two folding frames 110 are now two independent structures. The first leg 111 and the second leg 112 of each folding frame 110 are brought together, and then the two folding frames 110 are brought together. The two crossbars 230 are then placed together on the two folding frames 110. The chair fabric 220 will now partially cover the folding frames 110. Finally, the tie strips 210 are bonded to the chair fabric 220, connecting the tie strips 210 and the chair fabric 220 end-to-end to cover the entirety of the two folding frames 110 and the two crossbars 230. The chair is now in a folded state. Thus, the chair of the present application can even be directly placed into a small storage bag, such as a user's trouser pocket, in the folded state, effectively reducing the storage space of the chair for easy portability.

[0036] In one embodiment, the tie strap 210 is elastic. For example, the tie strap 210 is a stretchable strap. One end of the tie strap 210 is sewn to one end of the chair fabric 220, and the other end of the tie strap 210 is removably attached to the other end of the chair fabric 220 via Velcro. This allows the tie strap 210 and the chair fabric 220 to securely bind the two folding frames 110 and the two crossbeams 230 together in a closed state, preventing them from becoming loose.

[0037] like Figure 2 As shown, in one embodiment, the crossbeam 230 includes a beam body 231 and two insertion rods 232. The two insertion rods 232 are respectively arranged on both ends of the beam body 231, and the two insertion rods 232 face the same side of the beam body 231. The insertion rods 232 are used to plug the first leg 111 / the second leg 112.

[0038] It should be noted that, for example, the first leg 111 and the second leg 112 are both square-shaped structures with a through hole therein. Two insertion rods 232 are welded and fixed to the ends of the beam body 231, and the two insertion rods 232 face the same side of the beam body 231, so that the angle between the insertion rods 232 and the beam body 231 is 90 degrees. In this way, when the two insertion rods 232 are respectively inserted into the two first legs 111 or the two second legs 112, the crossbeam 230 is securely inserted and fixed to the first legs 111 or the second legs 112.

[0039] like Figure 1 and Figure 6 As shown, in one embodiment, a fastener 240 is provided on each end of the beam body 231 , and the fastener 240 is used to fasten the first leg 111 / the second leg 112 .

[0040] It should be noted that when the chair needs to be temporarily moved in the unfolded state but does not want to be disassembled into the folded state, a latch 240 is provided to secure the crossbeam 230 to the first leg 111 or the second leg 112. Specifically, the latch 240 is located at the end of the beam 231. When the insertion rod 232 is inserted into the first leg 111 or the second leg 112, the latch 240 will secure the first leg 111 or the second leg 112.

[0041] like Figure 6 As shown, in one embodiment, the fastener 240 includes a base 241, a buckle block 242 and a spring 243. The base 241 is set in the beam body 231, and the middle part of the buckle block 242 is rotatably set on the base 241. The spring 243 is respectively in contact with one end of the buckle block 242 and the base 241, so that the other end of the buckle block 242 is clamped with the first leg 111 / the second leg 112.

[0042] It should be noted that the base 241 is welded to the inner sidewall of the beam 231, and the buckle 242 is located on the outer side of the beam 231. The middle portion of the buckle 242 passes through the beam 231 to be rotatably connected to the base 241. For example, the buckle 242 and the base 241 are rotatably connected by a pin. Furthermore, the spring 243 abuts against one end of the buckle 242 and the base 241, respectively. In this way, under the elastic thrust of the spring 243, the other end of the buckle 242 is clamped and fixed close to the first leg 111 / the second leg 112.

[0043] like Figure 6 As shown, in one embodiment, a protrusion 244 is provided on one end of the buckle block 242 away from the spring 243 , and a locking hole is provided on both the first leg 111 and the second leg 112 , and the protrusion 244 is accommodated in the locking hole.

[0044] It should be noted that when the insertion rod 232 is inserted into the first leg 111 or the second leg 112 , the protrusion 244 will fall into the clamping hole, thereby clamping and fixing the first leg 111 or the second leg 112 .

[0045] like Figure 6 As shown, in one embodiment, the buckle block 242 includes a block body 2421 and a protrusion 2422. The protrusion 2422 is arranged in the middle of the block body 2421. The protrusion 2422 is rotatably connected to the base 241. The spring 243 abuts against one end of the block body 2421, and the protrusion 244 is located at the other end of the block body 2421.

[0046] It should be noted that the protruding piece 2422 is welded to the block 2421, so that the protruding piece 2422 is rotatably connected to the base 241 via a pin. In one embodiment, the raised portion 244 and the buckle block 242 are an integrally formed structure.

[0047] like Figure 6 As shown, in one embodiment, the buckle block 242 further includes a pressing piece 2423 , which is disposed on the end of the block 2421 close to the spring 243 , and the pressing piece 2423 is located on the side of the block 2421 away from the spring 243 .

[0048] It should be noted that the pressing piece 2423 is provided to facilitate applying pressing force to the block 2421. For example, the pressing piece 2423 is provided with a structure with a middle recess, so that it is convenient for the user to press with the thumb.

[0049] In one embodiment, the base 241 is welded to the inner sidewall of the beam 231 , thereby ensuring sufficient structural strength between the base 241 and the beam 231 .

[0050] like Figure 7As described above, in one embodiment, the portable folding chair 10 further includes two reinforcing rods 310 , wherein the two ends of one reinforcing rod 310 are respectively used to be inserted into one end of the two first legs 111 away from the beam 230 , and the two ends of the other reinforcing rod 310 are respectively used to be inserted into one end of the two second legs 112 away from the beam 230 .

[0051] It should be noted that, in order to improve the overall structural strength of the chair in the opened state, a reinforcing rod 310 is inserted at the bottom end of the first leg 111 and the second leg 112 .

[0052] like Figure 1 As shown, in one embodiment, a rubber plug 250 is provided at the end of the beam body 231 , so that the interior of the beam body 231 can be sealed to prevent dust and other debris from entering the beam body 231 .

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in the present invention can be understood to include but not be limited to locking and fixing with screws / screws and welding. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
