[0019] The beneficial effects of the present invention are as follows:

[0020] By setting a support rod, a roller and a swivel seat, two support structures can be used to transport long rod-shaped wooden processing raw materials, and the two ends of the wooden processing raw materials can be placed on the support rods of the two support structures respectively. During operation, the height of one end of the support rod can be bent down so that the wooden processing raw materials can be directly pushed and rolled to the upper part of the support rod, and then the lever of the vertical rod and the roller-shaped groove can be used to lift the wooden processing raw materials off the ground, and then the rollers can be used to transport them. The operation is convenient and fast, saving time and labor. In addition, during the transportation process, the support rod can be rotated by the swivel seat, so the angle of the vertical rod will not be restricted, which is convenient for the transporter to adjust the standing posture, and the use is more convenient.

[0021] By setting a support rod matching adjustment structure, an adjustment rod is set on the outside of the support rod, and screw holes are opened on the outer surface of the adjustment rod near both ends. When in use, the adjustment bolts can be screwed into the two screw holes respectively to fix the adjustment rod in different positions. When the adjustment rod protrudes from one end of the support rod, the raw materials for processing long strips of wooden products can be limited during transportation, thereby ensuring the stability of the raw materials for processing long strips of wooden products during transportation.

[0022] By setting up the combined structure, when in use, two bracket structures can be prepared, and then the two bracket structures can be combined together through the combined structure. When the length of the wood product processing raw materials to be transported is short and there is only one operator, the two bracket structures can be combined to carry out the transportation work, which can be suitable for transporting the wood product processing raw materials with a short length, thereby improving the application range of the entire bracket structure;

[0023] By setting a supporting structure to cooperate with the combined structure, the supporting structure is set at the center of the vertical pole. When the bracket structure is used alone, the first stud and the second stud can be screwed into the first ball head and the second ball head respectively, and the plate and the first connecting rod and the second connecting rod are limited to avoid shaking of the first connecting rod and the second connecting rod during transportation to affect use;

[0024] By setting a supporting structure, a combined structure and an adjustment structure, the adjusting rod is pulled out to the outside of the support rod and fixed by an adjusting bolt. After fixing, the cross rod is taken out and fixed to one end of the adjusting rod by a locking bolt. Then the first connecting column is taken out of the top cross beam and threadedly connected to one end of the bottom cross beam. Finally, the first connecting rod and the second connecting rod are rotated to a horizontal state, and the first stud and the second stud are connected with the first ball head and the second ball head. The first connecting rod and the second connecting rod can be placed horizontally above the support rod, so that plate-shaped wood processing raw materials can be transported, which further improves the scope of application and functionality of the entire support structure for wood processing and transportation.

On the one hand, the placement area of ​​the support rod 3 can be increased, which is suitable for wood materials of different diameters for wood product processing. On the other hand, the wood can be limited after being placed to prevent the wood from rolling down.

[0036] In this embodiment, a top cross beam 11 is installed at the top end of the vertical pole 4 , and a combined structure 21 is provided at one end of the top cross beam 11 and one end of the bottom cross beam 5 .

[0037] When in use, the top crossbeam 11 is used as a handle to facilitate the operation of the entire support structure. The combined structure 21 can be used to combine two or more support structures together, which is convenient for changing the use state and is suitable for various different use situations.

[0038] In this embodiment, the support rod 3 and the adjustment rod 8 are both arc-shaped, and the length of the adjustment rod 8 is half the length of the support rod 3 .

[0039] The arc-shaped support rod 3 can conveniently adapt to the shape of the cylindrical wood raw material for wood product processing, so that the wood raw material can be placed on the upper part of the support rod 3 more stably.

[0040] In this embodiment, the combined structure 21 includes a first connecting column 22 and a second connecting column 27, which are respectively connected to one end of the top cross beam 11 and the bottom cross beam 5, one end of the first connecting column 22 is rotatably connected to the first rotating head 23, one end of the first rotating head 23 is fixedly installed with a first connecting rod 24, one end of the first connecting rod 24 is threadedly connected to the first screw 25, and one end of the first screw 25 is fixedly connected to the first stud 26.

[0041] Prepare two support structures, namely support A and support B, rotate the first connecting rod 24 of support A at one end of the first connecting column 22 through the first turntable 23 to keep it in a horizontal state, and then screw the first stud 26 into one end of the top crossbeam 11 of support B to connect the top crossbeams 11 of the two support structures together.

[0042] In this embodiment, one end of the second connecting column 27 is rotatably connected to the second rotating head 28, one end of the second rotating head 28 is fixedly installed with a second connecting rod 29, one end of the second connecting rod 29 is threadedly connected to the second screw 30, and one end of the second screw 30 is fixedly connected to the second stud 31.

[0043] The second connecting rod 29 of bracket B is rotated through the second rotating head 28, and then the second stud 31 is screwed into one end of the bottom beam 5 of bracket A, so that the bottom beams 5 of the two bracket structures are connected together, and the first connecting rod 24 is used to combine bracket A and bracket B together.

[0044] In this embodiment, external hexagonal caps are provided between the first screw rod 25 and the first stud 26 and the second screw rod 30 and the second stud 31 . The first screw rod 25 and the second screw rod 30 are respectively the same length as the first connecting rod 24 and the second connecting rod 29 .

[0045] The external hexagonal cap can conveniently rotate the first stud 26 and the second stud 31 during operation, and the first screw 25 and the second screw 30 can be extended to one end of the first connecting rod 24 and the second connecting rod 29 by rotation, so that the length of the first connecting rod 24 and the second connecting rod 29 can be adjusted, thereby facilitating the adjustment of the spacing between the bracket A and the bracket B after combination.

[0046] In this embodiment, a support structure 12 is provided on the outside of the vertical pole 4, and the support structure 12 includes a support seat 13 and a cross bar 15. The support seat 13 is fixedly installed on the outside of the vertical pole 4, and the cross bar 15 is placed on the inner side of the support seat 13. The first ball head 16 and the second ball head 17 are respectively installed at both ends of the cross bar 15. A locking bolt 14 is threadedly connected between the front part of the support seat 13 and the cross bar 15.

[0047] A support structure 12 is provided outside the upright pole 4 near the middle position. When a single support structure is used, it is convenient to fix the first connecting rod 24 and the second connecting rod 29 to prevent the first connecting rod 24 and the second connecting rod 29 from shaking during use.

[0048] In this embodiment, a T-shaped groove 20 is opened at one end of the cross bar 15, a rotating column 18 is installed on the outside of the second ball head 17, one end of the rotating column 18 is connected to a limiting plate 19, and the second ball head 17 is rotatably connected to the cross bar 15 through the rotating column 18 and the limiting plate 19.

[0049] The first ball head 16 and the second ball head 17 are connected to the cross bar 15 in a rotatable manner, so that the first ball head 16 and the second ball head 17 can rotate in direction when in use, so as to correspond to the inclined first connecting rod 24 and the second connecting rod 29 .

[0050] In this embodiment, the outer surfaces of the first ball head 16 and the second ball head 17 are both provided with connecting holes, and the first stud 26 and the second stud 31 are threadedly connected to the connecting holes.

[0051] When fixing the first connecting rod 24 and the second connecting rod 29 , it is only necessary to thread the first stud 26 and the second stud 31 into the connecting holes on the outer surfaces of the first ball head 16 and the second ball head 17 , which is convenient and quick to operate.

[0052] In this embodiment, a rectangular block is provided in the middle of the crossbar 15 , and a rectangular groove is provided on the inner side of the support seat 13 , and the rectangular block fits in with the rectangular groove.

[0053] The rectangular block can cooperate with the rectangular groove to achieve mutual limitation, thereby improving the stability of the cross bar 15 and the support seat 13 after being connected.

[0054] In this embodiment, the locking bolt 14 is threadably matched with the internal thread groove 9 , and the inner walls of the top cross beam 11 and the bottom cross beam 5 are both provided with threads, which are threadably matched with the first connecting column 22 and the second connecting column 27 .

[0055] The locking bolt 14 can fix the cross bar 15 to one end of the adjusting rod 8, so as to facilitate the combination structure 21 to set a flat platform on the upper part of the support rod 3, so as to facilitate the transportation of plate-shaped wooden products and the processing of wood raw materials.

[0056] It should be noted that the present invention is a support structure for wood product processing and transportation. When in use, when transporting a rod-shaped long strip of wood product processing raw materials, two support structures are used, and the two support structures are pushed to the two ends of the wood product processing raw materials through the rollers 1, and then the support rods 3 are pushed to tilt through the vertical rods 4 so that one end of the vertical rods 4 is close to the ground, and then the rod-shaped long strip of wood product processing raw materials are rolled onto the support rods 3, and then the vertical rods 4 are used to tilt the support rods 3 so that the entire rod-shaped long strip of wood product processing raw materials are placed on the upper part of the support rods 3. Finally, two people use the vertical rods 4 to push or pull the wood product processing raw materials to move, and after moving to the required position, one end of the support rods 3 is brought close to the ground again, and the wood product processing raw materials are rolled out of the support rods 3. During the transportation process, since the support rods 3 can rotate on the top of the swivel seat 2, the angle of the vertical rods 4 can be rotated and will not be affected by the wood product processing raw materials, making transportation more convenient.

[0057] When the length of the raw materials for wood product processing is short and only one person is required to carry the raw materials, two support structures are prepared, namely support A and support B. The first screw rod 25 of support A is rotated to make the first stud 26 disengage from the first ball head 16. Then, the first connecting rod 24 is rotated at one end of the first connecting column 22 by the first rotating head 23 to keep the first connecting rod 24 in a horizontal state. Then, the first stud 26 is threadedly connected to one end of the top crossbeam 11 of support B.

[0058] The second screw rod 30 of the bracket B is rotated to disengage the second screw rod 30 from the second ball head 17, and then the second connecting rod 29 is rotated at one end of the second connecting column 27 by the second rotating head 28 to keep the second connecting rod 29 in a horizontal state, and then the second stud 31 is threadedly connected to one end of the bottom cross beam 5 of the bracket A to combine the bracket A and the bracket B together. During the carrying process, the user can use the first connecting rod 24 as a handle to place the wood processing raw materials on the upper part of the two support rods 3 for carrying, which is suitable for wood processing raw materials with shorter lengths;

[0059] When it is necessary to transport the raw materials for processing plate-like wooden products, rotate the first connecting column 22 so that the first connecting column 22 is separated from the top cross beam 11, and then the first connecting column 22 is threadedly connected to one end of the bottom cross beam 5, rotate to remove the locking bolt 14, take out the cross bar 15 in the vertical direction, and at the same time pull out the adjusting rod 8, use the adjusting bolt 10 to fix one end of the adjusting rod 8, and then place the cross bar 15 on the other end of the adjusting rod 8 and connect it with the internal thread groove 9 through the locking bolt 14. Finally, the first connecting rod 24 and the second connecting rod 29 at both ends of the bottom cross beam 5 are respectively rotated to a horizontal state through the first connecting column 22 and the second connecting column 27, and then the first screw 25 and the second screw 30 are rotated to adjust their lengths so that the first stud 26 and the second stud 31 can be screwed into the first ball head 16 and the second ball head 17. At this time, the first connecting rod 24, the first screw 25, the second connecting rod 29, and the second screw 30 are horizontally arranged above the support rod 3, which can be used to transport the raw materials for processing plate-like wooden products.
