Description

Technical Field

[0001] This utility model relates to the field of tree trunk fixing, and in particular to a forestry tree trunk fixing device. Background Technology

[0002] An existing patent (publication number: CN217771026U) proposes a tree trunk fixing and support device for landscaping projects, including a binding strap. The binding strap is equipped with multiple sleeve locking accessories, each of which includes a sleeve, a diagonal brace, and a binding strap insertion hole. A steel pipe is installed in the sleeve. One end of the binding strap is equipped with a buckle, which has buckle teeth that engage with anti-reverse teeth on the binding strap. The binding strap is equipped with multiple buffer clamping elements spaced apart from the sleeve locking accessories. Each buffer clamping element includes several integrally connected telescopic joints, each telescopic joint having a through hole that mates with the binding strap. The bottom of the steel pipe is equipped with a depth limiting element, which includes a foot sleeve. However, this device tightens to support trees of different diameters but does not have the effect of correcting tree tilt. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a circular collar composed of symmetrical semi-circular straightening sleeves, capable of multi-angle and multi-directional adjustment on a horizontal plane. Depending on the direction of the tree trunk's tilt, the collar is adjusted to precisely match the angle of the trunk's inclination, ensuring a proper correspondence between the support point and the tree's center of gravity. This prevents imbalances in corrective force due to support position deviations, resulting in a forestry tree trunk fixing device that better conforms to the tree's actual condition.

[0004] The objective of this utility model is achieved through the following technical solution: A forestry tree trunk fixing device includes a first support rod, a U-shaped base plate, side connecting ears, a first rotating shaft, a limiting slide plate, a semi-circular straightening sleeve, a trapezoidal sliding strip, a second outer plate, and a second inner plate. The lower part of the side connecting ears is connected to the U-shaped base plate. The lower side of the first support rod is in contact with the side connecting ears. The lower part of the first support rod is connected to a set of side connecting ears through the first rotating shaft. The lower part of the third rotating shaft is connected to the U-shaped base plate. The lower side of the second outer plate is in contact with the side connecting ears. The side connecting ears are symmetrically arranged at both ends of the second outer plate. The lower part of the second outer plate is connected to a set of side connecting ears through the third rotating shaft. The lower part of the second inner plate is adapted to the second outer plate. The lower part of the second inner plate is inserted into the second outer plate and slides up and down inside the second outer plate.

[0005] The second inner plate has multiple inner positioning holes, the second outer plate has an outer plate boss, the outer plate boss has an outer positioning hole, the inner positioning holes correspond to the outer positioning holes, the pins pass through the outer positioning holes and the inner positioning holes in sequence, the side of the limiting slide plate has a slide plate side connecting ear, a set of slide plate side connecting ears are distributed on the side of the second pivot, the upper sides of the second inner plate are in contact with a set of slide plate side connecting ears, and the upper part of the second inner plate is connected to the slide plate side connecting ears through the fourth pivot.

[0006] The upper sides of the first support rod are fitted with a set of sliding plate side connecting ears. The upper part of the first support rod is connected to a set of sliding plate side connecting ears through the second pivot. The symmetrical U-shaped base plates are fitted together and connected to the ground by pins. The tree root is placed in the middle of the symmetrical U-shaped base plates. Beneficial effects

[0007] 1. This utility model features a symmetrical U-shaped base plate placed on the ground and fixed therewith by multiple pins. The symmetrical U-shaped base plate serves as the load-bearing foundation for the entire device. A first support rod is connected to the U-shaped base plate via a first rotating shaft, allowing the lower part of the first support rod to connect to the shaft of the U-shaped base plate. The first support rod can rotate on the upper part of the U-shaped base plate. A trapezoidal slide bar is connected to a sliding plate side connecting ear via a second rotating shaft, allowing the upper part of the first support rod to connect to the side shaft of the limiting sliding plate. Both can rotate relative to each other. The trapezoidal slide bar is inserted into a trapezoidal groove, allowing the limiting sliding plate to be installed on the side of the semi-circular straightening sleeve and to slide up and down on the side of the semi-circular straightening sleeve. This design allows the height of the circular collar to be flexibly adjusted according to the tree's growth stage. For seedlings, the collar can be adjusted to a lower position to provide stable foundation support. When the tree grows to a certain height and the center of gravity of the trunk shifts upward, the collar can be adjusted upward to ensure that the support point is always in a position that effectively distributes the pressure on the trunk, meeting the support height requirements of the tree at different growth stages and avoiding the impact on tree growth due to a fixed height. Support rod number one supports the semi-circular straightening sleeve. Inner plate number two is inserted into outer plate number two. Outer plate number two and inner plate number two form a telescopic rod. The lower part of the telescopic rod is shaft-connected and mounted on another U-shaped base plate. The telescopic rod can rotate above this U-shaped base plate. Pins are inserted sequentially into the outer and inner positioning holes, limiting the telescopic rod's extension length and adjusting the support force. Another limiting slide plate is shaft-connected to the upper part of the telescopic rod. Symmetrical limiting slide plates are connected to symmetrical semi-circular straightening sleeves to ensure their alignment.

[0008] 2. This utility model features a first support rod designed to rotate and support the semi-circular straightening sleeves, and a telescopic rod designed to rotate and extend to support the semi-circular straightening sleeves. This allows the horizontal position of the symmetrical semi-circular straightening sleeves' mating circular collar to be adjusted. The horizontal position of the mating semi-circular straightening sleeves can be adjusted according to the tree trunk's tilt, providing support while simultaneously correcting the tree's horizontal position. The circular collar formed by the symmetrical semi-circular straightening sleeves can be adjusted at multiple angles and directions on the horizontal plane. Depending on the direction of the tree trunk's tilt, the collar is adjusted to precisely fit the angle of the tilt, ensuring a proper correspondence between the support point and the tree's center of gravity. This prevents imbalances in corrective force due to support position deviations, ensuring the support is more closely aligned with the tree's actual condition. This device requires no disassembly; simply rotating the first support rod, sliding the limiting slide, or adjusting the telescopic rod ensures the collar maintains a suitable fit and support force with the tree trunk.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A forestry tree trunk fixing device includes a first support rod 01, a U-shaped base plate 02, side connecting ears 03, a first rotating shaft 04, a limiting slide plate 06, a semi-circular straightening sleeve 09, a trapezoidal sliding strip 11, a second outer outer plate 12, and a second inner insert plate 14. The lower part of the side connecting ears 03 is connected to the U-shaped base plate 02. The symmetrical U-shaped base plate 02 is placed on the ground and fixed to the ground by multiple pins. The symmetrical U-shaped base plate 02 serves as the load-bearing foundation for the entire device. The lower side of the first support rod 01 fits against the side connecting ears 03. The lower part of the first support rod 01 is connected to a set of side connecting ears 03 through the first rotating shaft 04, so that the lower part of the first support rod 01 is axially connected to the U-shaped base plate 02. The first support rod 01 can rotate on the upper part of the U-shaped base plate 02. The lower part of the third rotating shaft 13 is connected to... The lower side of the U-shaped base plate 02 and the second outer plate 12 fits against the side connecting ears 03. The side connecting ears 03 are symmetrically arranged at both ends of the second outer plate 12. The lower part of the second outer plate 12 is connected to a set of side connecting ears 03 through the third rotating shaft 13. The lower part of the second inner plate 14 is adapted to the second outer plate 12. The lower part of the second inner plate 14 is inserted into the second outer plate 12 and slides up and down inside the second outer plate 12. The second outer plate 12 and the second inner plate 14 form a telescopic rod. The lower part of the telescopic rod is axially connected and installed on another U-shaped base plate 02. The telescopic rod can rotate above the other U-shaped base plate 02. Pins are inserted into the outer positioning hole 17 and the inner positioning hole 15 in sequence. The telescopic rod is limited by the pins to adjust the telescopic length and achieve the adjustment of the support force.

[0014] Example 2: The second inner plate 14 of this utility model has multiple inner positioning holes 15, and the second outer plate 12 has an outer plate boss 16 with an outer positioning hole 17. The inner positioning holes 15 correspond to the outer positioning holes 17. Pins pass through the outer positioning holes 17 and the inner positioning holes 15 in sequence. The side of the limiting slide plate 06 has a slide plate side connecting ear 08. A set of slide plate side connecting ears 08 is distributed on the side of the second rotating shaft 05. The upper two sides of the second inner plate 14 are in contact with a set of slide plate side connecting ears 08. The upper part of the second inner plate 14 is connected to the fourth rotating shaft 18. Connecting the side connecting ear 08 of the connecting plate, another limiting plate 06 on the upper part of the telescopic rod is connected to the shaft. The symmetrical limiting plate 06 is connected to the symmetrical semi-circular straightening sleeve 09 to ensure their alignment. The first support rod 01 is set to rotate to support the semi-circular straightening sleeve 09, and the telescopic rod is set to rotate and extend to support the semi-circular straightening sleeve 09. This allows the circular collar of the symmetrical semi-circular straightening sleeve 09 to be adjusted horizontally. The horizontal position of the aligned semi-circular straightening sleeve 09 can be adjusted according to the tilt position of the tree trunk, allowing the tree to be supported while its horizontal position is moved for correction. The circular collar formed by the symmetrical semi-circular straightening sleeves 09 can be adjusted at multiple angles and directions on the horizontal plane. Depending on the direction of the tree trunk's tilt, the collar is adjusted to precisely fit the angle of the tree trunk's tilt, ensuring that the support point and the tree trunk's center of gravity are reasonably aligned, avoiding imbalance of corrective force due to support position deviation, and making the support more closely fit the actual condition of the tree.

[0015] Example 3: The upper two sides of the first support rod 01 of this utility model are attached to a set of sliding plate side connecting ears 08. The upper part of the first support rod 01 is connected to a set of sliding plate side connecting ears 08 through the second rotating shaft 05, so that the upper part of the first support rod 01 is connected to the side shaft of the limiting sliding plate 06. The two can rotate relative to each other. The symmetrical U-shaped base plates 02 are aligned and connected to the ground through pins. The tree root is placed in the middle of the symmetrical U-shaped base plates 02.

[0016] Example 4: The semi-circular straightening sleeve 09 of this invention has a set of trapezoidal slide bars 11 on its side and a set of trapezoidal slide grooves 07 on its limiting slide plate 06. The trapezoidal slide bars 11 are adapted to the trapezoidal slide grooves 07, and are inserted into the trapezoidal slide grooves 07. The trapezoidal slide bars 11 slide within the trapezoidal slide grooves 07, allowing the limiting slide plate 06 to be installed on the side of the semi-circular straightening sleeve 09 and slide up and down on the side of the semi-circular straightening sleeve 09. This design allows the height of the circular collar to be flexibly changed according to the growth stage of the tree. For seedlings, the collar can be adjusted to a lower position to provide stable basic support; when the tree grows to a certain height and the center of gravity of the trunk shifts upward, the collar can be adjusted upward to ensure that the support point is always in a position that can effectively distribute the pressure on the trunk, meeting the support height requirements of the tree at different growth stages and avoiding the impact on tree growth due to a fixed height. The first support rod 01 supports the semi-circular straightening sleeve 09. The upper and lower ends of the semi-circular straightening sleeve 09 have symmetrical arc-shaped anti-collision plates 10. The symmetrical semi-circular straightening sleeves 09 fit together, and the tree trunk is placed between the symmetrical semi-circular straightening sleeves 09. This device does not require disassembly. By simply rotating the first support rod 01, sliding the limiting slide plate 06, or adjusting the telescopic rod, the collar can always maintain a suitable fit and support force with the tree trunk.

[0017] Example 5: The installation steps of this utility model are as follows: First, insert the trapezoidal slide bar 11 into the trapezoidal slide groove 07. Connect the upper and lower ends of the semi-circular straightening sleeve 09 to the arc-shaped anti-collision plate 10. Connect the upper part of the first support rod 01 to the side connecting ear 08 of the slide plate through the second rotating shaft 05. Connect the lower part of the first support rod 01 to the side connecting ear 03 through the first rotating shaft 04. Connect the lower part of the second outer plate 12 to the side connecting ear 03 through the third rotating shaft 13. Insert the second inner plate 14 into the second outer plate 12. Connect the upper part of the second inner plate 14 to the side connecting ear 08 of the slide plate through the fourth rotating shaft 18. Align the inner positioning hole 15 with the outer positioning hole 17. Pass the pin through the outer positioning hole 17 and the inner positioning hole 15 in sequence.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
