[0043] The present invention will be further described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0044] Example 1

[0045] like Figures 1-4 As shown, this embodiment provides a foldable fishing chair, which includes a folding frame, a front horizontal seat tube 2, and a rear horizontal seat tube 3. The folding frame, front horizontal seat tube 2, and rear horizontal seat tube 3 are preferably made of aluminum alloy profiles. The front horizontal seat tube 2 is rotatably connected to the upper front end of the folding frame, and the rear horizontal seat tube 3 is rotatably connected to the upper rear end of the folding frame, allowing the foldable fishing chair to have both an unfolded and a folded state. Crucially, the rear horizontal seat tube 3 has a through-hole 4 for inserting a backrest frame 11, which extends through the rear horizontal seat tube 3 and reaches the upper end of the folding frame.

[0046] It should be noted that the folding frame can adopt a similar folding structure disclosed in patent documents with publication number CN221356341U, and the straight insertion hole 4 extends to the upper end of the folding frame through the rear side transverse seat pipe 3, including two structures as follows:

[0047] The first kind: the straight insertion hole 4 extends to the inside of the upper end of the folding frame after extending through the rear side transverse seat pipe 3. This structure does not need to add additional structural members, which is equivalent to opening a hole in the inside of the upper end of the folding frame as an extension of the straight insertion hole, thereby enhancing the stability and reliability of the backrest frame on the fishing chair by cooperating the folding frame with the rear side transverse seat pipe 3.

[0048] The second kind: the straight insertion hole 4 extends to the outside of the upper end of the folding frame after extending through the rear side transverse seat pipe 3. This structure needs to fix additional structural members and open a hole as an extension of the straight insertion hole on the outside of the upper end of the folding frame or the lower part of the rear side transverse seat pipe 3.

[0049] The two straight insertion hole structures have the same function, but the first kind of straight insertion hole structure is preferred in this embodiment.

[0050] According to a preferred embodiment of the present embodiment, as shown in Figures 1-4 The folding frame includes two sets of folding supports 1, each set of folding supports 1 includes a front support pipe 6 and a rear support pipe 7 connected in the middle, the front side transverse seat pipe 2 is respectively connected to the upper end of the front support pipe 6 of the two sets of folding supports 1 through the L-shaped connecting piece 5, and the rear side transverse seat pipe 3 is respectively connected to the upper end of the rear support pipe 7 of the two sets of folding supports 1 through the L-shaped connecting piece 5. Since the backrest frame 11 usually includes two backrest rods, the folding frame usually includes two rear support pipes 7, so as to ensure that the backrest frame 11 can be stably installed and fixed to the foldable fishing chair, the number of straight insertion holes 4 is at least two. Of course, the number of straight insertion holes can also be increased according to the structure of the backrest frame 11 and the structure of the folding frame. When the number of straight insertion holes 4 is two, the two straight insertion holes 4 are respectively located at the two ends of the rear side transverse seat pipe 3, and each straight insertion hole 4 extends to the inside of the upper end of the rear support pipe 7 through the rear side transverse seat pipe 3.

[0051] It should be noted that the straight insertion hole 4 is essentially a hole that can be directly inserted into the backrest frame 11 for fixation. As shown in Figure 5 The backrest frame 11 can be quickly and conveniently inserted and fixed to the foldable fishing chair through the straight insertion hole 4, and after use, the backrest frame 11 can also be quickly and conveniently pulled out from the foldable fishing chair for folding, and the overall operation process is simple and convenient, and can be quickly completed. Since the straight insertion hole 4 extends to the inside of the upper end of the rear support pipe 7, the folding frame and the rear side transverse seat pipe 3 can bear the pressure after connecting the backrest frame 11, thereby improving the stability and reliability of the backrest frame 11 on the foldable fishing chair.

[0052] According to another preferred embodiment of the present embodiment, as shown inFigures 1-5 As shown in the figure, the axis of the straight insertion hole 4 is perpendicular to the axis of the rear lateral tube 3, and the axis of the straight insertion hole 4 coincides with the axis of the upper part of the rear support tube 7 (when the rear support tube 7 is an integral tube, the axes of the straight insertion hole 4, the upper part of the rear support tube 7, and the lower part of the rear support tube 7 coincide; when the rear support tube 7 is a split tube as shown in Figure 1 、 2 , 4, the axis of the straight insertion hole 4 coincides with the axis of the upper part of the rear support tube 7), and the straight insertion hole 4 of this structure is equivalent to first vertically penetrating the rear lateral tube 3 and then extending from the upper end surface of the rear support tube 7 to the inside of the rear support tube 7. At this time, the straight insertion hole 4 is in an inclined state when the folding frame is unfolded, and the inclination angle is the same as the inclination angle of the rear support tube 7 after the folding frame is unfolded. The straight insertion hole 4 of this structure is suitable for fixing a backrest frame 11 that includes two parallel backrest rods.

[0053] According to an alternative embodiment of the present embodiment, the axis of the straight insertion hole 4 can also intersect the axis of the rear lateral tube 3 and the axis of the upper part of the rear support tube 7, respectively. The straight insertion hole 4 of this structure is equivalent to first obliquely penetrating the rear lateral tube 3 and then extending from the side surface of the upper end of the rear support tube 7 to the inside of the rear support tube 7. The straight insertion hole 4 of this structure is suitable for fixing a backrest frame 11 that includes two intersecting backrest rods.

[0054] The foldable fishing chair of the present embodiment is mainly used in combination with the existing foldable backrest 8. When used in combination with the foldable backrest 8, the foldable backrest 8 can be conveniently and quickly installed and fixed to the foldable fishing chair through the straight insertion hole 4, and after use, the foldable backrest 8 can also be quickly and conveniently extracted for folding. Not only does this enable the foldable fishing chair to be effectively combined with the backrest, thereby improving the comfort of use of the foldable fishing chair, but also has the advantages of simple and convenient operation process and strong practicality.

[0055] Embodiment 2

[0056] On the basis of embodiment 1, the structure of the foldable fishing chair is further optimized in the present embodiment.

[0057] As shown in Figure 1 、 2 , 5, 6, the L-shaped connecting pieces 5 on the folding support 1 are all arranged in the same direction in the present embodiment, so that the two sets of folding supports 1 can be located on the two sides of the rear lateral support tube after folding. Since the lower ends of the two sets of folding supports 1 are located on the rear lateral support tube and do not interfere with each other, a larger volume of the claw 10 can be installed on the premise of maintaining the minimum folding volume of the folding support 1, thereby improving the use stability of the foldable fishing chair on a non-planar foundation.

[0058] Embodiment 3

[0059] As shown in Figures 7-10As shown in the figure, the embodiment provides a back direct insertion type foldable seat, which comprises a foldable fishing chair and a foldable back 8.

Since the folding frame comprises two rear support pipes 7 and the foldable back 8 comprises two foldable back rods 9 which can be folded towards each other, in order to stably install and fix the foldable back 8 to the foldable fishing chair, the number of direct insertion holes 4 is preferably two. Of course, the number of direct holes can also be increased according to the structure of the foldable back 8 and the structure of the folding frame. When the number of direct insertion holes 4 is two, the two direct insertion holes 4 are respectively located at the two ends of the rear side transverse seat pipe 3, and each direct insertion hole 4 penetrates the rear side transverse seat pipe 3 and extends to the inside of the upper end of the rear support pipe 7, so that the foldable back rods 9 of the foldable back 8 can be respectively inserted and fixed in the direct insertion holes 4.

[0061] As shown in the figure, Figures 7-11 The foldable back 8 can be quickly and conveniently inserted and fixed to the foldable fishing chair through the direct insertion hole 4, and after use, the foldable back 8 can also be quickly and conveniently pulled out from the foldable fishing chair for folding, so that the overall operation process is simple and convenient, and quick completion is facilitated. Since the direct insertion hole 4 extends to the inside of the upper end of the rear support pipe 7, after connecting the foldable back 8, the folding frame and the rear side transverse seat pipe 3 can both bear pressure, and the stability and reliability of the foldable back 8 on the foldable fishing chair are correspondingly improved.

[0062] It should be noted that the foldable fishing chair in the present embodiment has the same structure as the foldable fishing chair in embodiment 1, and the specific implementation manner can be referred to embodiment 1, and the specific structure can be referred to Figures 1-6 , and the same parts will not be described again.

At this time, the straight insertion hole 4 is in an inclined state when the folding frame is unfolded, and the inclination angle is the same as the inclination angle of the rear support tube 7 after the folding frame is unfolded. The straight insertion hole 4 of this structure is suitable for fixing the foldable backrest 8 which includes two parallel backrest rods 9, and the lower end of the foldable backrest can be inserted at an inclination angle along the axis direction of the straight insertion hole 4. Figure 1 、 2 As shown in FIG. 4, the axis of the straight insertion hole 4 coincides with the axis of the upper part of the rear support tube 7, and the structure of the straight insertion hole 4 is equivalent to vertically penetrating the rear lateral tube 3 first, and then extending from the upper end surface of the rear support tube 7 to the inside of the rear support tube 7. At this time, the straight insertion hole 4 is in an inclined state when the folding frame is unfolded, and the inclination angle is the same as the inclination angle of the rear support tube 7 after the folding frame is unfolded. The straight insertion hole 4 of this structure is suitable for fixing the foldable backrest 8 which includes two parallel backrest rods 9, and the lower end of the foldable backrest can be inserted at an inclination angle along the axis direction of the straight insertion hole 4.

[0064] According to an alternative embodiment of the present embodiment, the axis of the straight insertion hole 4 can also intersect with the axis of the rear lateral tube 3 and the axis of the upper part of the rear support tube 7, respectively. The straight insertion hole 4 of this structure is equivalent to penetrating the rear lateral tube 3 first at an inclination, and then extending from the side surface of the upper end of the rear support tube 7 to the inside of the rear support tube 7. The straight insertion hole 4 of this structure is suitable for fixing the foldable backrest 8 which includes two intersecting backrest rods 9.
