[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. Example 1:

[0033] like Figure 1-7 As shown, the field training chair includes two symmetrically arranged chair frames 1 and two groups of folding components 2 arranged on opposite sides of the two chair frames 1.

[0034] The outer walls of the two chair frames 1 are fixedly connected to the handrails 3, and the two handrails 3 are provided with a slide groove 7 on the opposite side. The inner wall of the slide groove 7 is slidably matched with a slide plate 4 through a slider. The inner walls of the two slide plates 4 are respectively rotatably connected to the table board 1 5 and the table board 2 6. The inner walls of the table board 1 5 and the table board 2 6 are respectively provided with a limit groove 1 8 and a limit groove 2 9, and the limit groove 1 8 and the limit groove 2 9 are mutually limited.

[0035] After the user sits on the field training chair, he can slide out the slides 4 on both sides, and then rotate the table board 2 6 from a state perpendicular to the ground to a state parallel to the ground, and then rotate the table board 1 5, and the limit groove 1 8 and the limit groove 2 9 engage with each other. At this time, the user can place auxiliary items such as water cups and fishing gear on the top of the table board 1 5 and the table board 2 6 for easy access.

[0036] By providing a slide plate 4, table board 1 5 and table board 2 6, and utilizing the cooperation between the slide plate 4 and the handrail 3, the extension length of table board 1 5 and table board 2 6 can be adjusted to meet the different needs of users. Table board 1 5 and table board 2 6 can provide support for auxiliary supplies, making it convenient for users to take them and use them, thereby improving the ease of use of the device. Table board 1 5 and table board 2 6 can also be rotated, folded and retracted, thereby reducing the occupied area when not in use.

[0037] In this embodiment, the tops of the two chair frames 1 are fixedly connected to a fixing rod 10, the inner wall of the fixing rod 10 is movably connected to an insertion rod 11, and the inner walls of the two insertion rods 11 are fixedly connected to the same backrest cloth 12.

[0038] When the backrest cloth 12 is damaged, the insertion rod 11 and the backrest cloth 12 are pulled out from the fixing rod 10, and then a new insertion rod 11 and the backrest cloth 12 are inserted into the fixing rod 10 to complete the replacement of the backrest cloth 12.

[0039] The inner walls of the two chair frames 1 are fixedly connected to a second fixing rod 13 , the inner wall of the second fixing rod 13 is movably plugged with a second insertion rod 14 , and the inner walls of the two insertion rods 14 are fixedly connected to the same seat cushion cloth 15 .

[0040] When the cushion cloth 15 is damaged, the insertion rod 2 14 and the cushion cloth 15 are extracted from the insertion rod 2 14 , and then a new insertion rod 2 14 and the cushion cloth 15 are inserted into the fixing rod 2 13 to complete the replacement of the cushion cloth 15 .

[0041] By providing a fixing rod 10, an inserting rod 11, a fixing rod 2 13 and an inserting rod 2 14, when the backrest cloth 12 or the seat cushion cloth 15 is damaged, it can be quickly replaced, which further improves the convenience of use of the device. In addition, this method does not require the entire field training chair to be scrapped, and can reduce the cost of use.

[0042] In this embodiment, the folding component 2 includes a staggered connecting rod 16 and a connecting rod 2 17, one end of which is rotatably connected to the chair frame 1, and the other end of which is provided with a strip groove 25, and a fixing rod 24 is fixedly connected to the outer wall of the chair frame 1, and the fixing rod 24 and the strip groove 25 are movably limited and matched.

[0043] The two chair frames 1 are pushed toward the axis of the connecting shaft 18 so that the two chair frames 1 are close to each other, and the field training chair can be folded and stored. Example 2:

[0044] Field training chair, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1-7 As shown:

[0045] The second connecting rod 17 is provided with a locking assembly for locking the connecting shaft 18 . The locking assembly includes a button 20 and a second slide 22 . The button 20 can only be axially slidably connected to the inner wall of the second connecting rod 17 , and the second slide 22 is opened on the inner wall of the button 20 .

[0046] The connecting shaft 18 is fixedly connected to the connecting rod 16, and the connecting rod 2 17 is rotatably connected to the connecting shaft 18. The outer wall of the connecting shaft 18 located inside the connecting rod 2 17 is provided with teeth 19, and the inner wall of the button 20 is provided with tooth grooves 23 adapted to the teeth 19.

[0047] A spring 21 is buckled on the inner wall of the second sliding groove 22 , and the other end of the spring 21 is buckled on the outer wall of the connecting shaft 18 .

[0048] In this embodiment: when the field training chair needs to be unfolded, the button 20 is pressed inward so that the tooth groove 23 is disengaged from the tooth 19, and the spring 21 is compressed. At this time, the connecting shaft 18 is not restricted, and the connecting rod 16 can be rotated open. At this time, the field training chair can be unfolded and used. After unfolding, the button 20 is released, and the elastic force of the spring 21 is used to drive the tooth groove 23 to engage with the tooth 19 again to lock the connecting shaft 18. When the field training chair needs to be folded, the above steps are repeated again. When the connecting shaft 18 contacts the restriction, the connecting rod 1 16 and the connecting rod 2 17 can be rotated and retracted to complete the folding and storage of the field training chair.

[0049] By providing the teeth 19 and the tooth grooves 23 and utilizing the mutual engagement of the teeth 19 and the tooth grooves 23, the field training chair can maintain its state when unfolded or folded, thereby improving stability when unfolded and preventing it from falling apart when folded.

[0050] Working principle: when it needs to be unfolded for use, the button 20 is pressed inward, and the tooth groove 23 is disengaged from the tooth 19, and the spring 21 is compressed. At this time, the connecting shaft 18 is unrestricted, and the connecting rod 16 can be rotated open, and the field training chair can be unfolded for use. After the user sits on the field training chair, the slides 4 on both sides can be slid out, and then the table board 2 6 is rotated from a state perpendicular to the ground to a state parallel to the ground, and then the table board 1 5 is rotated, and the limit groove 1 8 and the limit groove 2 9 are engaged with each other. At this time, the user can place auxiliary items such as water cups and fishing gear on the top of the table board 1 5 and the table board 2 6 for easy access and use. After use, the table board 1 5 and the table board 2 6 are rotated to fold them up, and the slide 4 is reset, and then the button 20 is pressed inward again to contact the rotation lock of the connecting shaft 18, and the connecting rod 1 16 and the connecting rod 2 17 can be rotated and folded, thereby completing the folding and storage of the field training chair.

[0051] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
