[0005] (II) Technical solution

[0006] The solution adopted by the utility model to solve the above-mentioned technical problems is a telescopic folding chair, comprising two fixed legs arranged opposite to each other, two rotating legs that can rotate relative to the fixed legs, and a seat cushion connected between the top ends of the two fixed legs and the top ends of the two rotating legs; the rotating legs and the fixed legs are arranged crosswise; wherein the top ends of the two fixed legs are respectively connected to backrest rods, the backrest rods are coaxially arranged with the fixed legs and can approach or move away from the fixed legs, a backrest is connected between the two backrest rods, and the backrest and the seat cushion are arranged in a staggered manner.

[0007] Specifically, the overall cross-section of the seat cushion is roughly L-shaped, and the plane where the portion of the seat cushion close to the backrest for supporting the user's back is located is roughly parallel to the plane where the backrest is located, so that a gap is formed between the two, so that when the backrest rod is stored, the backrest and the seat cushion will not interfere with each other, so that the backrest rod and the backrest can be stored smoothly.

[0008] In some embodiments, the bottom ends of the two fixed legs and the two rotating legs are connected to a base via a universal head, and a spike-shaped insertion portion is provided at the bottom end of the base. When the user unfolds the telescopic folding chair for use, the insertion portion can be inserted into the soil to improve its stability during use.

[0009] In some embodiments, the seat cushion is arranged above the two fixed legs and the two rotating legs, and the backrest is connected between the two backrest rods. The backrest is relatively placed behind the seat cushion so that the backrest and the seat cushion are staggered. When the backrest rod makes a telescopic movement, the backrest will not interfere with the seat cushion, thereby realizing the storage and deployment of the backrest.

[0010] By adopting the above scheme, the telescopic folding chair can be quickly unfolded and folded through two groups of cross-arranged rotating legs and fixed legs; and the backrest rod that can be retracted relative to the fixed legs can be pulled out when in use to improve the comfort of the user; the backrest can also be pushed down when storing to better store the telescopic folding chair, reduce the storage space, and be more convenient to carry.

[0011] In some embodiments, the fixed leg is provided with a cavity along its length direction, the backrest rod is adapted in the cavity, and can perform telescopic movement along the cavity to move closer to or away from the fixed leg.

[0012] In some embodiments, the length of the backrest rod is less than the length of the fixed leg, so that the cavity can accommodate the backrest rod, thereby reducing the space occupied by the telescopic folding chair.

[0013] In some embodiments, the backrest rod and the cavity are tightly matched, so that after the backrest rod moves along the cavity to adjust its extended size, the stability during use is improved.

[0014] In some embodiments, a locking structure capable of locking the backrest rod may be connected to the top end of the fixed leg to keep the backrest rod in an extended state.

[0015] In some embodiments, the backrest is connected to a fixing portion at an end of the backrest rod away from the fixing leg, and the fixing portion can abut against the fixing leg at a periphery of the cavity.

[0016] By adopting the above scheme, when the backrest rod is moved and stored along the cavity of the fixed leg, the fixing portion can abut against the periphery of the fixed leg located in the cavity to prevent the backrest rod from being completely stored in the cavity, thereby facilitating the user to operate the extension and retraction of the backrest rod.

[0017] In some embodiments, the backrest also includes a connecting portion that can be connected to the fixed leg, the connecting portion is arranged on a side of the backrest close to the fixed leg, and the connecting portion is sleeved on the fixed leg and can move along the length direction of the fixed leg.

[0018] By adopting the above scheme, when the user operates the backrest rod to perform telescopic movement along the cavity, the connecting portion will move along the fixed leg and drive the backrest to move, thereby realizing the telescopic movement of the backrest and reducing the storage space of the telescopic folding chair.

[0019] In some embodiments, a fixing sleeve is disposed at the top end of the fixing leg, and the connecting portion is located on the fixing leg on a side of the fixing sleeve facing away from the backrest rod.

[0020] By adopting the above scheme, when the backrest rod moves and unfolds along the cavity of the fixed leg, the connecting portion can abut against the fixed sleeve to prevent the backrest from being separated from the fixed leg, making it convenient for the user to operate the telescopic backrest rod; at the same time, the backrest is restricted from moving in the space between the fixed sleeve and the rotating connection between the fixed leg and the rotating leg; and when the backrest moves to the point where its connecting portion abuts against the fixed sleeve, the backrest is in a fully unfolded state; when the backrest moves to the point where it abuts against the rotating connection between the fixed leg and the rotating leg, the backrest is in a fully retracted state.

[0021] In some embodiments, the two connecting parts are located on one side of the backrest and are connected with a connecting belt, and the connecting belt is made of flexible material; the provision of the connecting belt improves the connection stability of the backrest on the fixed leg.

[0023] By adopting the above scheme, when the telescopic folding chair needs to be unfolded, the user operates the second section to rotate relative to the fixed leg and move the other end thereof toward the side away from the bottom end of the fixed leg to unfold, and operates the first section to rotate relative to the fixed leg and move the other end thereof toward the side away from the top end of the fixed leg to unfold, thereby unfolding the seat cushion; when the telescopic folding chair needs to be stored, the user operates the second section to rotate relative to the fixed leg and move the other end thereof toward the side close to the bottom end of the fixed leg to store, until the second section abuts against the lower half of the fixed leg; operates the first section to rotate relative to the fixed leg and move the other end thereof toward the side close to the top end of the fixed leg to store, until the first section abuts against the upper half of the fixed leg, thereby folding the seat cushion and completing the storage.

[0024] In some embodiments, the first section and the second section are connected together by a connecting frame, the first section is hinged to the connecting frame, the second section is fixed to the connecting frame, and the connecting frame is sleeved on the fixed leg and can rotate relative to the fixed leg.

[0025] In some embodiments, the connecting frame includes a covering portion covering the rear side of the second section, and two connecting rods connected to both sides of the top end of the covering portion, wherein the two connecting rods are hinged to the fixed leg at portions close to the covering portion, and are hinged to the first section at one end away from the covering portion; the second section is fixedly connected to the fixed leg at one end close to the fixing leg and partially extends out of the covering portion; the end of the second section extending out of the covering portion can support the fixing leg after the second section is unfolded.

[0026] In some embodiments, one end of the second section extending out of the covering portion is recessed inward to form a recess so that the second section can be matched with the fixed leg after the second section is unfolded, thereby increasing the supporting force of the second section supporting the fixed leg, thereby increasing the stability when unfolded and used.

[0027] By adopting the above scheme, when the telescopic folding chair needs to be stored, the user operates the second section to move it toward the lower half of the fixed leg and drives the covering part to move synchronously, and the connecting rod rotates around the fixed leg so that the end away from the covering part moves toward the upper half of the fixed leg. Since there is space between the two connecting rods, the fixed leg can be avoided during the rotation process; and the first section can be operated to move toward the upper half of the fixed leg and enable it to collide with the upper half of the fixed leg to complete the storage, and the size after storage is smaller.

[0028] In some embodiments, a first support rod and a second support rod are cross-arranged between the front of the two rotating legs, and the first support rod and the second support rod are respectively rotatably connected to different rotating legs; the second support rod is connected to the third support rod through a first cross-rod connecting piece, and there is a gap between the second support rod and the third support rod for accommodating the first support rod; the other end of the first support rod and the other end of the third support rod are respectively rotatably connected to different fixed legs;

[0029] A fourth support rod and a fifth support rod are cross-arranged between the rear of the two fixed legs, and the fourth support rod and the fifth support rod are respectively rotatably connected to different fixed legs; the fifth support rod is connected to the sixth support rod through a second cross rod connecting piece, and there is a gap between the fifth support rod and the sixth support rod for accommodating the fourth support rod; the other end of the fourth support rod and the other end of the sixth support rod are respectively rotatably connected to different rotating legs.

[0057] like Figure 1-Figure 9 As shown, the utility model provides a telescopic folding chair, comprising two relatively arranged fixed legs 100, two rotating legs 200 that can rotate relative to the fixed legs 100, and a seat cushion 300 connected between the top ends of the two fixed legs 100 and the top ends of the two rotating legs 200; the rotating legs 200 and the fixed legs 100 are arranged crosswise; wherein, the top ends of the two fixed legs 100 are respectively connected with a backrest rod 400, the backrest rod 400 is coaxially arranged with the fixed legs 100 and can be close to or away from the fixed legs 100, a backrest 500 is connected between the two backrest rods 400, and the backrest 500 and the seat cushion 300 are arranged in a staggered manner. Specifically, the overall cross-section of the seat cushion 300 is roughly L-shaped, and the plane of the portion of the seat cushion 300 near the backrest 500 for supporting the back of the user is roughly parallel to the plane of the backrest 500, so that a gap is formed between the two, so that when the backrest rod 400 is stored, the backrest 500 and the seat cushion 300 will not interfere with each other, so that the backrest rod 400 and the backrest 500 can be stored smoothly. In some embodiments, the bottom ends of the two fixed legs 100 and the two rotating legs 200 are connected to the base 101 through a universal head, and the bottom end of the base 101 is provided with a spike-shaped insertion portion 101a. When the user unfolds the telescopic folding chair for use, the insertion portion 101a can be inserted into the soil to improve its stability during use. In some embodiments, the seat cushion 300 is arranged above the two fixed legs 100 and the two rotating legs 200, and the backrest 500 is connected between the two backrest rods 400, and the backrest 500 is relatively arranged behind the seat cushion 300, so that the backrest 500 and the seat cushion 300 are arranged in a staggered manner, and when the backrest rod 400 is telescopic, the backrest 500 will not interfere with the seat cushion 300, and the storage and unfolding of the backrest 500 is realized. With the above scheme, the telescopic folding chair can be quickly unfolded and folded through two groups of cross-arranged rotating legs 200 and fixed legs 100; and the backrest rod 400 that can be telescopic relative to the fixed legs 100 can be pulled out when in use to improve the comfort of the user; and the backrest 500 can also be pushed down when stored to better store the telescopic folding chair, reduce the storage space, and be more convenient to carry.

In some embodiments, the length of the backrest rod 400 is less than the length of the fixed leg 100, so that the cavity 10 can accommodate the backrest rod 400, reducing the space occupied by the telescopic folding chair. In some embodiments, the backrest rod 400 is tightly matched with the cavity 10, so that the backrest rod 400 is moved along the cavity 10 to adjust its extended size, and the stability during use is improved. In some embodiments, the backrest 500 is connected to the fixing portion 50 of the backrest rod 400 at one end away from the fixed leg 100, and the fixing portion 50 can be against the periphery of the fixed leg 100 located in the cavity 10. By adopting the above solution, when the backrest rod 400 moves and is stored along the cavity 10 of the fixed leg 100, the fixed portion 50 can abut against the periphery of the fixed leg 100 located in the cavity 10 to prevent the backrest rod 400 from being completely stored in the cavity 10, so as to facilitate the user to operate the telescopic backrest rod 400. In some embodiments, the backrest 500 also includes a connecting portion 51 that can be connected to the fixed leg 100, the connecting portion 51 is arranged on a side of the backrest 500 close to the fixed leg 100, and the connecting portion 51 is sleeved on the fixed leg 100 and can move along the length direction of the fixed leg 100. By adopting the above solution, when the user operates the backrest rod 400 to telescope along the cavity 10, the connecting portion 51 will move along the fixed leg 100 and drive the backrest 500 to move, thereby realizing the telescopic backrest 500 and reducing the storage space of the telescopic folding chair. In some embodiments, a fixing sleeve 11 is provided at the top of the fixed leg 100, and the connecting portion 51 is located on the fixed leg 100 on the side of the fixing sleeve 11 away from the backrest rod 400. With the above solution, when the backrest rod 400 moves and unfolds along the cavity 10 of the fixed leg 100, the connecting portion 51 can abut against the fixing sleeve 11 to prevent the backrest 500 from being separated from the fixed leg 100, so as to facilitate the user to operate the extension and retraction of the backrest rod 400; at the same time, the backrest 500 is restricted from moving in the space between the fixing sleeve 11 and the rotation connection between the fixed leg 100 and the rotating leg 200; and when the backrest 500 moves to the point where its connecting portion 51 abuts against the fixing sleeve 11, the backrest 500 is in a fully unfolded state; when the backrest 500 moves to the point where it abuts against the rotation connection between the fixed leg 100 and the rotating leg 200, the backrest 500 is in a fully retracted state.In some embodiments, the two connecting parts 51 are located on one side of the backrest 500 and are connected with a connecting belt 52, and the connecting belt 52 is made of flexible material; the setting of the connecting belt 52 improves the connection stability of the backrest 500 on the fixed leg 100.

[0059] In some embodiments, the rotating leg 200 includes a first section 20 and a second section 21; the first section 20 is relatively arranged above the fixed leg 100 and can rotate relative to the fixed leg 100; the second section 21 is relatively arranged below the fixed leg 100 and can rotate relative to the fixed leg 100; and the other end of the first section 20 is connected to one end of the seat cushion 300, and there is a gap between the first section 20 and the second section 21 to accommodate the fixed leg 100. With the above scheme, when the telescopic folding chair needs to be unfolded, the user operates the second section 21 to rotate relative to the fixed leg 100 and move the other end thereof toward the side away from the bottom end of the fixed leg 100 to unfold, and operates the first section 20 to rotate relative to the fixed leg 100 and move the other end thereof toward the side away from the top end of the fixed leg 100 to unfold, thereby unfolding the seat cushion 300; when the telescopic folding chair needs to be stored, the user operates the second section 21 to rotate relative to the fixed leg 100 and move the other end thereof toward the side close to the bottom end of the fixed leg 100 to store, until the second section 21 abuts against the lower half of the fixed leg 100; operates the first section 20 to rotate relative to the fixed leg 100 and move the other end thereof toward the side close to the top end of the fixed leg 100 to store, until the first section 20 abuts against the upper half of the fixed leg 100, thereby folding the seat cushion 300 and completing the storage. In some embodiments, the first section 20 and the second section 21 are connected together by a connecting frame 22, the first section 20 is hinged to the connecting frame 22, the second section 21 is fixed to the connecting frame 22, and the connecting frame 22 is sleeved on the fixed leg 100 and can rotate relative to the fixed leg 100.
