Description

Technical Field

[0001] The utility model belongs to the technical field of support frames, and in particular relates to a tree support and fixing device for greening projects. Background Art

[0002] After a new tree is planted or transplanted, it is easy for it to fall over because its root system has not yet fully grasped the soil, resulting in the failure of the transplant. People generally use several wooden sticks tied with iron wires or ropes, and nailed to the trunks with iron nails to fix the trees. One tree needs four pieces of wood to fix it, which not only wastes wood but also easily damages the bark and trunk of the transplanted tree, and the fixation is not reliable. In the prior art, although there are tree support frames, the fixed ring structure and the bracket length of the existing tree support frames cannot be adjusted, and cannot adapt to trees of different thicknesses. At the same time, it is time-consuming and laborious to install and disassemble the fixed support, which increases the cost of tree transplantation. Utility Model Content

[0003] The utility model solves the shortcomings of the prior art and provides a tree supporting and fixing device for greening projects which is adaptable to tree trunks of different thicknesses and can be reused.

[0004] To achieve the above-mentioned purpose, the utility model firstly proposes a tree support and fixing device for greening projects, comprising a plurality of supporting legs and a fixing ring; a locking block is fixed on one end of the fixing ring, and a rack is fixed on the other end; a through groove matching the size of the rack is provided on the locking block, and the through groove runs through both sides of the locking block; a locking device is provided in the locking block, and the locking device limits the rack inserted into the through groove to prevent the rack from retreating; a plurality of sliding blocks are also sleeved on the fixing ring, and the sliding blocks are slidably connected to the fixing ring, and retractable supporting legs are hinged on the outer sides of the sliding blocks and the locking blocks.

[0005] The rack of the utility model has a certain flexibility. When in use, the support legs are adjusted to a suitable length, and the locking block is placed close to the tree trunk to be supported. The rack is inserted from one side of the through slot of the locking block and then passed out from the other side. After the position of the sliding block is adjusted, the locking device can fix the rack. The cooperation between the rack and the locking block enables the support frame body to fix trees of different sizes, making installation and disassembly easier. While improving adaptability, it can effectively reduce the labor intensity of the staff. The sliding block sleeved on the outside of the rack allows the support legs to be evenly distributed on the outside of the tree trunk and can adjust the support height, making the tree support more secure. At the same time, the sleeved sliding block and support legs can also be conveniently stored when the support frame body is not in use, improving the convenience of use.

[0006] In this embodiment, the locking device includes a gear and a worm gear mechanism, the worm gear mechanism includes a worm wheel and a worm, a mounting cavity is provided in the locking block, the gear is rotatably mounted in the mounting cavity, the gear matches the rack, one side of the gear extends into the through slot, so that after the rack is inserted into the through slot, the rack meshes with the gear; a worm wheel linked to the gear is coaxially mounted in the mounting cavity at the rear side of the gear, a rotating shaft is provided in the mounting cavity and at the lower side of the worm wheel, the rotating shaft is arranged vertically with the rotating axis of the worm wheel, a worm matching the worm wheel is coaxially mounted on the upper side of the rotating shaft, and one end of the rotating shaft is hinged in the mounting cavity The other end is a free end, and the locking block is provided with an arc-shaped through groove on a side wall corresponding to the free end of the rotating shaft, and the free end of the rotating shaft extends out of the locking block from the arc-shaped through groove, and a locking handle is threadedly connected to the end of the locking block extending out of the locking block, and the rotating shaft and the arc-shaped through groove are slidably connected, and a sliding groove that is connected to the arc-shaped through groove and matches the shape is also provided in the locking block, and a slider is slidably connected to the inside of the sliding groove, and the slider is connected to the rotating shaft, and the slider is connected to the bottom of the sliding groove by a tensioning spring. In the initial state, the tensioning spring supports the rotating shaft through the slider, so that the worm on the rotating shaft engages with the worm wheel.

[0007] When the rack is inserted into the through hole, the operator presses down the locking handle to separate the worm and the worm wheel with the rotating shaft. At this time, the worm wheel and the gear can rotate normally. When the rack moves to a certain position, the staff releases the locking handle and tightens the spring to make the worm and the worm wheel abut. When the rack needs to be loosened, the locking handle is pressed down again. When the worm and the worm wheel are separated, the rack can be directly pulled out. The cooperation of the upper and lower hinged worm and worm wheel makes the locking device easy to operate. By using the self-locking property of the worm gear mechanism, the entire locking device can maintain a stable locking state, thereby preventing the rack from accidentally moving or loosening.

A contraction opening is provided at the lower end of the mother rod, and a quick release clamp is sleeved outside the contraction opening. The sub-rod is slidably inserted into the mother rod. When in use, the quick release clamp can contract the lower side of the mother rod under the action of the contraction opening to clamp the sub-rod. The cooperation of the quick release clamp, the mother rod and the sub-rod makes the support leg have the characteristics of simple structure, high reliability, more convenient operation, and strong stability and safety.

[0011] In this embodiment, a rubber pad is fixed on the side of the locking block and the sliding block facing the tree. The rubber pad can reduce the pressure of the locking block and the sliding block on the tree, which can effectively protect the bark and trunk of the tree. At the same time, the rubber pad can increase the friction between the support frame body and the tree, making the tree more firmly fixed.

[0012] To sum up, the cooperation between the rack and the locking block of the utility model enables the support frame body to fix trees of different sizes, which is simpler to install and disassemble. While improving adaptability, it can effectively reduce the labor intensity of the staff. The sliding block sleeved on the outside of the rack can allow the supporting legs to be evenly distributed on the outside of the tree trunk and can adjust the supporting height, making the tree support more secure; at the same time, the sleeved sliding block and supporting legs can be conveniently stored when the support frame body is not in use, thereby improving ease of use. The cooperation between the worm and the worm wheel hinged up and down makes the operation of the locking device simple, and utilizes the self-locking property of the worm, which enables the entire locking device to maintain a stable locking state, thereby preventing the rack from accidentally moving or loosening.

[0021] like Figure 1-5 As shown, a tree support and fixing device for greening engineering includes a plurality of support legs and a fixing ring;

[0022] A locking block 1 is fixed on one end of the fixed ring, and a rack 2 is fixed on the other end. The locking block 1 is provided with a through groove 3 that matches the size of the rack 2. The through groove 3 runs through both sides of the locking block 1. A locking device is provided in the locking block 1. The locking device limits the rack 2 inserted into the through groove 3 to prevent the rack 2 from retreating. Three sliding blocks 4 are also sleeved on the fixed ring. The sliding blocks 4 are slidably connected to the fixed ring, and retractable supporting legs are hinged on the outer sides of the sliding blocks 4 and the locking block 1.

[0023] The rack 2 of the utility model has a certain flexibility. When in use, the support legs are adjusted to a suitable length, and the locking block 1 is placed close to the tree trunk to be supported. The rack 2 is inserted from one side of the through slot 3 of the locking block 1 and then passed out from the other side. After the position of the sliding block 4 is adjusted, the locking device can fix and tighten the rack 2. The cooperation between the rack 2 and the locking block 1 enables the support frame body to fix trees of different sizes, making installation and disassembly easier. While improving adaptability, it can effectively reduce the labor intensity of the staff. The sliding block 4 sleeved on the outside of the rack 2 allows the support legs to be evenly distributed on the outside of the tree trunk and can adjust the support height, making the tree support more secure; at the same time, the sleeved sliding block 4 and the support legs can also be conveniently stored when the support frame body is not in use, improving the convenience of use.

[0024] The locking device includes a gear 5 and a worm gear mechanism, the worm gear mechanism includes a worm wheel 6 and a worm 8, a mounting cavity is provided in the locking block 1, the gear 5 is rotatably mounted in the mounting cavity, the gear 5 matches the rack 2, one side of the gear 5 extends into the through slot 3, so that after the rack 2 is inserted into the through slot 3, the rack 2 meshes with the gear 5; a worm wheel 6 linked to the gear 5 is coaxially mounted in the mounting cavity at the rear side of the gear 5, a rotating shaft 7 is provided in the mounting cavity and at the lower side of the worm wheel 6, the rotating shaft 7 is arranged perpendicular to the rotating axis of the worm wheel 6, one end of the rotating shaft 7 is hinged in the mounting cavity, and the other end is a free end, the locking block 1 is provided with an arcuate through slot 10 on a side wall corresponding to the free end of the rotating shaft 7, the free end of the rotating shaft 7 The locking block 1 extends out of the arc-shaped through groove 10, and a locking handle 9 is threadedly connected to one end of the locking block 1. The rotating shaft 7 is slidably connected to the arc-shaped through groove 10. A worm 8 matching the worm wheel 6 is coaxially mounted on the upper side of the rotating shaft 7. A slide groove 11 communicating with the arc-shaped through groove 10 and matching in shape is provided inside the locking block 1. A slider 12 is slidably connected inside the slide groove 11. The slider 12 is connected to the rotating shaft 7, and the slider 12 is connected to the bottom of the slide groove 11 through a tensioning spring 13. Further, the locking handle 9 is composed of a fixed handle on a locking nut. By rotating the locking handle 9, the locking handle 9 is pressed against the outer wall of the locking block 1, and the position of the rotating shaft 7 is locked by friction.

[0025] In the initial state, the tensioning spring 13 supports the rotating shaft 7 through the slider 12, so that the worm 8 on the rotating shaft 7 is engaged with the worm wheel 6. At the same time, by rotating the locking handle 9, the locking handle 9 is pressed against the outer wall of the locking block 1, and the friction force is used to ensure that the rotating shaft 7 is stable in this position.

[0026] When the rack 2 passes through the through hole, the operator presses down the locking handle 9, so that the rotating shaft 7 drives the worm 8 to separate from the worm wheel 6.
