[0002] The original intention of the design of foldable tables and chairs is to solve the problems of storage and carrying of tables and chairs in the case of limited space or frequent relocation. By using a foldable mechanism, these tables and chairs can be folded into a smaller shape when not in use, thus saving space and facilitating carrying.
[0003] Since people have different heights, foldable tables and chairs with different heights are needed. At present, the height of foldable tables and chairs is usually fixed and cannot be adjusted during use, which cannot meet the needs of different people. Content of the Utility Model
[0004] The purpose of the utility model is to provide a portable military folding table and chair to solve the problem that the height of the foldable table and chair cannot be adjusted in the prior art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: a portable military folding table and chair, including: a cushion, a table board, a first bracket and a second bracket. Leg assemblies are arranged on both sides below the cushion. Storage openings one for receiving the leg assemblies are arranged on both sides below the cushion. A first fixing rod is fixedly arranged inside the concave cavity at the bottom of the cushion. A connecting groove is arranged on one side of the cushion close to the first fixing rod. Circular fixing blocks are symmetrically arranged on both sides of the outside of the cushion;
[0006] A second fixing rod is fixedly arranged inside the concave cavity at the bottom of the table board. Fixing parts cooperating with the fixing blocks are movably arranged on both sides of the table board. A storage opening two is arranged on one side of the table board away from the second fixing rod;
[0007] A turning part is arranged at the lower end of the first bracket. The turning part is located in the connecting groove and is turnably connected with the first fixing rod. Adjusting grooves are symmetrically arranged on both sides of the first bracket. Each adjusting groove is composed of a sliding groove and a toothed groove;
[0008] The second bracket is slidably arranged inside the first bracket. Adjusting blocks that can rotate are symmetrically arranged and fixedly connected to the lower surface of the second bracket. The two adjusting blocks respectively pass through the corresponding adjusting grooves. The upper end of the second bracket is rotatably connected with the second fixing rod. A torsion spring is arranged in the middle of the upper end of the second bracket. A fixed stop block is arranged beside the second bracket for limiting the side wall of the adjacent concave cavity.
[0009] Further, the leg assembly includes a first leg, a second leg, a third leg, a fourth leg, a first anti-slip bar, and a second anti-slip bar. The first leg and the second leg are movably connected by a bolt. The third leg and the fourth leg are movably connected by a bolt. The first leg and the third leg are fixedly connected by the first anti-slip bar. The second leg and the fourth leg are fixedly connected by the second anti-slip bar.
[0010] Further, a first connecting rod and a second connecting rod are arranged on both sides below the seat cushion. The upper ends of the first leg and the third leg are respectively movably connected to the first connecting rod. The upper ends of the second leg and the fourth leg are respectively movably connected to the second connecting rod.
[0011] Further, the plurality of legs are respectively composed of a sleeve and a rod. The rod is slidably arranged in the sleeve. The two sleeves are fixedly connected by the corresponding anti-slip bar. A plurality of positioning holes are arranged on the sleeve, and bolts are arranged to cooperate with the positioning holes.
[0012] Further, a circular convex block is arranged on the tooth groove, and a fixing groove is arranged below the adjusting block to cooperate with the circular convex block.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] The present utility model has two usage modes. One is that it can be used as a seat, and the other is that it can be used as a table and chair. When used as a seat, first take out the leg assembly from the first storage opening and pull it open. Fix the legs by inserting pins into each leg. Then, pull the tabletop to make the first bracket rotate around the first fixing rod in the connecting groove, so that the first bracket abuts against one side of the connecting groove. Thus, the connecting groove provides a supporting force for the first bracket. Since the fixing blocks symmetrically arranged on both outer sides of the cushion are circular and the fixing parts movably arranged on both sides of the tabletop can rotate, the fixing parts can rotate around the fixing blocks during the rotation of the tabletop, so that the fixing parts are always connected to the fixing blocks, enabling the tabletop to be used as a backrest. When used as a table and chair, based on the usage of the seat, remove the fixing parts from the fixing blocks. Since the upper end of the second bracket is rotatably connected to the second fixing rod and a torsion spring is arranged in the middle of the upper end of the second bracket, the torsion spring will bounce the tabletop open after the fixing parts are removed. Since there is a gap between the second fixing rod and one side of the tabletop, the force of the torsion spring will make the tabletop have a tendency to tilt. At the same time, the tabletop is limited by the fixed stop block and remains in a flat state. The torsion spring provides a large pre-tightening force for the flat tabletop to facilitate supporting items on the tabletop, such as a water cup or a book. When it is necessary to adjust the height of the tabletop, the height of the tabletop can be adjusted by pulling the two adjusting blocks up and down to make the two adjusting blocks slide in the sliding grooves of the corresponding adjusting grooves. When the two adjusting blocks slide in the sliding grooves of the corresponding adjusting grooves, they will drive the second bracket to slide up and down in the first bracket. After determining the height of the tabletop, rotate the two adjusting blocks to make the two adjusting blocks respectively snap into the tooth grooves of the corresponding adjusting grooves, fixing the second bracket in the first bracket, thus completing the height adjustment of the tabletop. Furthermore, the height of the folding table and chair can be adjusted to meet the needs of different people.
[0015] When the present utility model is not in use, the pins on the legs can be removed, and then the leg assembly can be folded up and placed into the first storage opening. Press the tabletop to fold the tabletop and the cushion, and then fix the fixing parts and the fixing blocks. Thus, the volume of the table and chair can be reduced, saving storage space and making it more convenient to carry.

[0027] A second fixing rod 21 is fixedly arranged inside the concave cavity at the bottom of the table board 2. Fixing members 22 cooperating with the fixing blocks 14 are movably arranged on both sides of the table board 2. A second storage opening 23 is arranged on one side of the table board 2 away from the second fixing rod 21.
[0028] The lower end of the first support 3 is located in the connecting groove 13 and is rotatably connected to the first fixing rod 12. Adjusting grooves 31 are symmetrically arranged on both sides of the first support 3. The adjusting groove 31 is composed of a sliding groove 311 and a toothed groove 312.
[0029] A turning part 32 is arranged at the lower end of the first support 3. The turning part 32 is located in the connecting groove 13 and is turnably connected to the first fixing rod 12. Through the arrangement of the turning part 32, the table board 2 can coincide with the seat cushion 1, thus facilitating storage and placement. Adjusting grooves 31 are symmetrically arranged on both sides of the first support 3. The adjusting groove 31 is composed of a sliding groove 311 and a toothed groove 312. A circular convex block 3121 is arranged in the toothed groove 312. A fixing groove cooperating with the circular convex block 3121 is arranged below the adjusting block 41, so that the adjusting block 41 can not only slide in the sliding groove 311 of the adjusting groove 31, but also be fixed in the toothed groove 312 of the adjusting groove 31.
[0030] The second support 4 is slidably arranged in the first support 3. Adjusting blocks 41 that can rotate are symmetrically arranged on the lower surface of the second support 4. The two adjusting blocks 41 respectively pass through the corresponding adjusting grooves 31. The upper end of the second support 4 is rotatably connected to the second fixing rod 21. A torsion spring 42 is arranged in the middle of the upper end of the second support 4. A fixed stop block 43 is arranged beside the second support 4 for limiting the side wall of the adjacent concave cavity.
[0031] The utility model has two usage modes, one is that it can be used as a seat, and the other is that it can be used as a table and chair; when using it as a seat, first take out the leg assembly 5 from the storage opening 11 and pull it open, fix the legs by inserting pins into each leg, then pull the table board 2 to allow the first bracket 3 to rotate around the fixing rod 12 in the connecting groove 13, so that the first bracket 3 is against one side of the connecting groove 13, and then the connecting groove 13 provides a supporting force for the first bracket 3, and since the fixing blocks 14 symmetrically arranged on both sides of the seat cushion 1 are circular, the fixing parts 22 movably arranged on both sides of the table board 2 can rotate, and then during the rotation of the table board 2, the fixing parts 22 can rotate around the fixing blocks 14, so that the fixing parts 22 are always connected to the fixing blocks 14, so that the table board 2 can be used as a chair back. When the table and chair are in use, the fixing piece 22 is removed from the fixing block 14 based on the use of the seat. Since the upper end of the second bracket 4 is rotatably connected to the fixing rod 21, a torsion spring 42 is provided in the middle of the upper end of the second bracket 4, so that after the fixing piece 22 is removed, the torsion spring 42 will bounce the table top 2 open. Since there is a gap between the fixing rod 21 and one side of the table top 2, the force of the torsion spring 42 will make the table top 2 have a tendency to tilt up. At the same time, the table top 2 is limited by the fixed stopper 43 and remains in a straight state. The torsion spring 42 provides a large pre-tightening force for maintaining the table top 2 in a straight state, so as to support items on the table, such as a cup or a book. When the table needs to be adjusted When adjusting the height of the board 2, the height of the table board 2 can be adjusted by pulling the two adjustment blocks 41 up and down to make the two adjustment blocks 41 slide in the slide groove 311 of the corresponding adjustment groove 31. When the two adjustment blocks 41 slide in the slide groove 311 of the corresponding adjustment groove 31, they will drive the second bracket 4 to slide up and down in the first bracket 3. When the height of the table board 2 is determined, the two adjustment blocks 41 are rotated to make the two adjustment blocks 41 respectively snap into the tooth groove 312 of the corresponding adjustment groove 31, so that the second bracket 4 is fixed in the first bracket 3, thereby completing the height adjustment of the table board 2, and then the height of the folding table and chair can be adjusted to meet the needs of different groups of people.
[0032] When use is finished, the latch on the leg can be removed, and the leg assembly 5 can be folded and placed into the storage opening 11, the table top 2 can be pressed to fold the table top 2 and the seat cushion 1, and then the fixing piece 22 can be fixed to the fixing block 14, thereby reducing the volume of the table and chair, saving storage space, and making it more convenient to carry.
[0033] Furthermore, the outrigger assembly 5 includes outrigger one 51, outrigger two 52, outrigger three 53, outrigger four 54, anti-slip bar one 55 and anti-slip bar two 56. The outrigger one 51 and the outrigger two 52 are movably connected by a bolt. The outrigger three 53 and the outrigger four 54 are movably connected by a bolt. The outrigger one 51 and the outrigger three 53 are fixedly connected by the anti-slip bar one 55. The outrigger two 52 and the outrigger four 54 are fixedly connected by the anti-slip bar two 56. The setting of the two anti-slip bars makes the outrigger assembly 5 more stable during use. When in use, the bolt needs to be inserted into each outrigger to fix the outrigger. When not in use, the bolt can be removed, and then each outrigger can be folded and stored.
[0034] Furthermore, on both sides below the seat cushion 1, there are connecting rod one 15 and connecting rod two 16. The upper ends of the outrigger one 51 and the outrigger three 53 are respectively movably connected to the connecting rod one 15. The upper ends of the outrigger two 52 and the outrigger four 54 are respectively movably connected to the connecting rod two 16. The outrigger one 51 and the outrigger three 53 can rotate around the connecting rod one 15. The outrigger two 52 and the outrigger four 54 can rotate around the connecting rod two 16. Thus, the outriggers can be placed into the storage opening one 11, which can reduce the volume of the table and chair, save storage space, and make it more convenient to carry.
[0035] Furthermore, multiple outriggers are respectively composed of a sleeve 57 and a rod 58. The rod 58 is slidably arranged in the sleeve 57. The two sleeves 57 are fixedly connected by the corresponding anti-slip bar. Multiple positioning holes 571 are arranged on the sleeve 57, and a bolt 572 that cooperates with the positioning holes 571. When in use, the rod can be slid in the corresponding sleeve by pulling the two anti-slip bars to adjust the length of the outrigger. After the length of the outrigger is determined, the bolt is inserted into the positioning hole of the corresponding sleeve to complete the length adjustment of the outrigger, and then complete the height adjustment of the seat cushion 1, so that the user can adjust the height of the table and chair according to their own needs at will, and the adjustment method is simple.
[0036] Working principle: When the chair is in use, first take out the leg assembly 5 from the storage opening 11 and pull it open, fix the legs by inserting the pins into each leg, then pull the table board 2 to let the first bracket 3 rotate around the fixing rod 12 in the connecting groove 13, so that the first bracket 3 is against one side of the connecting groove 13, and then the connecting groove 13 provides a supporting force for the first bracket 3. Since the fixing blocks 14 symmetrically arranged on both sides of the outer side of the seat cushion 1 are circular, the fixing parts 22 movably arranged on both sides of the table board 2 can rotate, and then during the rotation of the table board 2, the fixing parts 22 can rotate around the fixing blocks 14, so that the fixing parts 22 are always connected to the fixing blocks 14, so that the table board 2 can be used as a chair back; when the height needs to be adjusted, the two anti-slip rods can be pulled to let the sleeve rod slide in the corresponding sleeve to adjust the length of the leg. After the length of the leg is determined, the plug is inserted into the positioning hole of the corresponding sleeve to complete the length adjustment of the leg, and then the height adjustment of the seat cushion 1 is completed. When the table and chair are in use, the fixing piece 22 is removed from the fixing block 14 based on the use of the seat. Since the upper end of the second bracket 4 is rotatably connected to the fixing rod 21, a torsion spring 42 is provided in the middle of the upper end of the second bracket 4, so that after the fixing piece 22 is removed, the torsion spring 42 will bounce the table board 2 open. Since there is a gap between the fixing rod 21 and one side of the table board 2, the force of the torsion spring 42 will make the table board 2 have a tendency to tilt up. At the same time, the table board 2 is limited by the fixed stopper 43 and remains in a straight state. The torsion spring 42 provides a large force for maintaining the table board 2 in a straight state. Pre-tightening force is provided to facilitate supporting desktop items, such as cups or books. The height of the table top 2 can be adjusted by pulling the two adjustment blocks 41 up and down to make the two adjustment blocks 41 slide in the corresponding adjustment grooves 31. When the two adjustment blocks 41 slide, the second bracket 4 will be driven to slide up and down in the first bracket 3. After the height of the table top 2 is determined, the two adjustment blocks 41 are rotated so that the two adjustment blocks 41 are respectively inserted into the corresponding adjustment grooves 31, thereby fixing the second bracket 4 in the first bracket 3, thereby completing the height adjustment of the table top 2.
