Detailed Description

The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.

As shown in fig. 1, the invention provides a tree transplanting and fixing bracket, which is used for shaping and supporting trees after the trees are transplanted, so that the trees can be effectively prevented from being inclined or even toppled under the influence of wind power or other external force under the condition that the root systems of the trees are not reached.

As an embodiment of the present application, the tree transplantation fixing bracket includes: a hoop 1 circumferentially surrounding a trunk 4 and a plurality of supports 2 swingably arranged on the lower part or side part of the hoop 1; specifically, the upper portion of the supporting member 2 may be swingably coupled to the hoop 1 by using a flexible connection (using rubber, a soft belt, a chain, etc.) or a pin joint, and the lower portion of the supporting member 2 may move toward or away from the trunk 4 during swinging, so that a position suitable for supporting can be obtained on the supporting surface 5 (ground).

Further, the hoop 1 is composed of a plurality of bendable hoop rods 10 connected end to end in sequence, and the transplanting personnel can select the proper number of the hoop rods 10 to match the circumference of the trunk 4, so as to improve the universality of the hoop 1; the hoop rods 10 are telescopic along their length so that the hoop 1 can expand radially outwardly therealong. Based on the structure, as the trunk 4 grows thicker, the hoop 1 can correspondingly encircle the trunk 4, and compared with a tree hoop without expansion capacity in the prior art, the tree hoop disclosed by the invention solves the technical problem that the tree hoop excessively tightens the trunk 4, and avoids the influence on normal growth of the tree due to excessive tightening.

In one embodiment, the hoop 10 may be made of a rubber material such as TPE/TPR.

Considering that the hoop 1 is inevitably used in severe environments such as sunshine, rain and the like, the hoop rod 10 made of rubber only is aged or even fails; it will be appreciated that the hoop pole 10 may become stiff and continue to tighten the tree or may break, losing support.

Thus, in another embodiment (see fig. 2 and 3), the band 10 comprises a flexible body 11 made of rubber, elastic plastic, elastic metal, etc., which has bendability and scalability along its length; along the length direction of the hoop rod 10, a spiral groove 110 is arranged on the outer circumferential surface of the flexible main body 11; the hoop rod also comprises a tension spring 12 correspondingly embedded in the spiral groove 110 and a connecting piece used for connecting the hoop rods 10 end to end; wherein the tension spring 12 is used to bear an axial tensile force, and when the hoop rod 10 is elongated in the axial direction, the tension spring 12 can exert a reaction force to resist the elongation of the hoop rod 10.

Referring to fig. 4 and 5, as an embodiment of the present invention, the connection member includes a rotary support sleeve 111 configured at one end of the flexible body 11, an external screw 13 partially rotatably disposed in the rotary support sleeve 111, and an internal screw 14 configured at the other end of the flexible body 11, wherein the external screw 13 is threadably engaged with the internal screw 14.

As an embodiment of the present invention, the male screw 13 includes a rotation portion 132 rotatably disposed in the rotation support sleeve 111, a male screw (not shown) extending to the outside of the rotation support sleeve 111, and a screw portion 131 disposed outside the rotation support sleeve 111; the rotating portion 132, the external thread portion, and the screwing portion 131 are integrally formed. Based on the above structure, the male screw part is used for screwing the female screw member 14, the rotation part 132 can restrict the male screw member 13 from being detached from the rotation support sleeve 111, and the screwing part 131 can facilitate the rotation of the male screw member 13 by the transplanting person.

Specifically, the outer circumferential shape of the screw part 131 may be configured in a regular polygonal shape so that the implantation person can screw the connection member manually or using a tool such as a wrench.

As an embodiment of the present invention, a cavity 15 is formed inside the flexible main body 11, so that the flexibility and the scalability along the length direction thereof can be more easily realized;

correspondingly, the spiral groove 110 is formed with a plurality of spiral concave rings 112 towards the cavity 15; the extension spring 12 comprises a plurality of periodically combined spiral single bodies 121; the spiral single bodies 121 are embedded in the spiral concave ring 112 in a one-to-one correspondence. It will be appreciated that when the flexible body 11 is bent or stretched, the deformation portion occurs mostly at the spiral concave ring 112, thereby improving the deformation performance of the flexible body 11.

Further, the internal thread member 14 is configured with an internal thread hole 140, and the other end of the flexible body 11 is provided with a through hole 150 communicating with both the cavity 15 and the internal thread hole 140. Based on this setting, the screwing length of the male screw part and the female screw 14 can be adjusted; it will be appreciated that the implantation personnel can adjust the circumference of the entire hoop 1 to a small extent by adjusting the length of the threaded connection of the external threaded portion to the internal threaded bore 140 to better fit the thickness of the trunk 4. For example, when a plurality of hoop rods 10 are sequentially combined end to form the hoop 1, the inner diameter of the hoop is slightly larger than the circumference of the trunk 4, and a part of the external thread part can be screwed into the cavity 15; therefore, the distance between two adjacent flexible bodies 11 is reduced, and the purpose of reducing the circumference of the whole hoop 1 is achieved.

Referring to fig. 6, as an embodiment of the present invention, the supporting member 2 is connected to the hoop 1 through a joint portion 3, the joint portion 3 adjustably embraces the hoop rod 10, and the supporting member 2 is swingably connected to the joint portion 3.

It should be noted that the adjustable embracing of the engaging portion 3 on the hoop pole 10 means that the engaging portion 3 can be clasped and fixed on the hoop pole 10; when the engaging portion 3 is not fixed to the hoop pole 10, the engaging portion 3 may move in the longitudinal direction of the hoop pole 10 or may rotate in the circumferential direction of the hoop pole 10.

Referring to fig. 7 and 8, further, the joint 3 includes a plurality of lower joints 31 made of hard material such as hard metal or hard plastic, the lower joints 31 are substantially semi-annular and have a first connecting end and a second connecting end; the first connecting end is flexibly connected or pivoted with an upper combining part 32, and the upper combining part 32 can be combined and fixed on the second connecting end, so that the hoop pole 10 can be encircled between the upper combining part 32 and the lower combining part 31. The upper bonding portion 32 may be made of a hard material, may be substantially semi-annular, and may be rubber, a soft tape, or the like. Of course, the above-mentioned surrounding effect can also be achieved by respectively combining and fixing the two ends of the upper combining portion 32 to the first connecting end and the second connecting end.

Still further, a plurality of the lower combining parts 31 are fixed into a whole by a combining plate 33, and the supporting member 2 is connected to the combining plate 33; therefore, the positions of the lower combining parts 31 can be fixed, the hoop rod 10 is not easy to move, and the connection stability of the hoop rod and the supporting piece 2 can be enhanced.

Referring to fig. 7 and 8, as an embodiment of the present invention, the second connection end is configured with a clamping sleeve 311, a sleeve groove 310 is formed in the clamping sleeve 311, and a clamping block 3102 is formed at an inner side portion of the sleeve groove 310; correspondingly, a clip 321 capable of being inserted into the sleeve groove 310 is configured on the upper coupling portion 32, and a clip hole 320 capable of being engaged with the clip 3102 is formed on the clip 321.

In order to allow the strap 321 to be smoothly inserted into the groove 310 and to be firmly fixed by the latch 3102, the side portion defining the latch 3102 is configured with a slope 3101 gradually extending from top to bottom to the groove 310, and the lower portion of the latch 3102 is substantially horizontal.

Referring to fig. 8 and 9, as an embodiment of the present invention, the joint 3 includes a connection plate 341 fixed to the coupling plate 33, and a first cylinder 34 fixed to one end of the connection plate 341; the support member 2 includes a support portion 20, one end of which is configured with a first slot 200 for receiving the first cylinder 34, and the first cylinder 34 is rotatably disposed in the first slot 200.

In a specific application scenario, the hand-held support 2 is required to be physically and difficultly attached to the hoop 10 at the joint 3, so that a detachable connection between the support 2 and the joint 3 is defined.

Referring to fig. 10 and 11, specifically, the two sides of the first chute body 200 are respectively provided with a second chute body 210; an elastic piece 212 is arranged in the second groove body 210, a second cylinder 21 is slidably mounted in the second groove body, and under the action of the elastic piece 212, the second cylinder 21 is popped out of the second groove body 210; part of the second cylinder 21 can extend out of the second slot 210, and the second cylinder 21 cannot be completely separated from the second slot 210. Based on this structure, when the first cylinder 34 is inserted into or pulled out of the first slot 200, the two second cylinders 21 located at both sides of the first cylinder 34 in the radial direction can be retracted into the second slot 210; when the insertion of the first cylinder 34 is completed, the two second cylinders 21 can limit the first cylinder 34 from separating from the first slot 200; thereby forming a quick-assembly-disassembly structure between the supporting piece 2 and the joint part 3, and being more beneficial to the use of the transplanting personnel.

Furthermore, the elastic element 212 is a spring, so as to avoid the pressing position deviation between the second cylinder 21 and the elastic element 212 from affecting the pop-up effect, the positioning rod 211 is defined on the second cylinder 21, and the elastic element 212 is sleeved on the positioning rod 211.

As an embodiment of the present invention, the second groove 210 has an open mouth 2100, and a part of the second cylinder 21 can protrude out of the open mouth 2100; the upper end and the lower end of the opening part 2100 are both formed with cambered surfaces 2101 which can be attached to the second cylinder 21. Therefore, external impurities are not easy to remain in the second groove body 210, and the second cylinder 21 is prevented from being clamped by the impurities to lose the limiting effect.

As an embodiment of the present invention, along the axial direction of the second cylinder 21, anti-slip plates 201 are disposed on both sides of the second groove 210; when the first cylinder 34 is inserted into the first housing 200, the two anti-slip plates 201 restrain the first cylinder 34 or the connecting plate 341, thereby preventing the first cylinder 34 from slipping out of the first housing 200 in the axial direction thereof.

Referring to fig. 1, as an embodiment of the present invention, the other end of the supporting part 20 is flexibly connected or pivoted with a ground plate 22, and the ground plate 22 can be fixed to the supporting surface 5 by a fixing part 220 such as a peg, a long steel nail, or the like. Compared with the structure that the supporting part 20 is directly inserted into the supporting surface 5 in the prior art, the contact area between the grounding plate 22 and the supporting surface 5 is larger, so that the relative position between the other end of the supporting part 20 and the supporting surface 5 is more stable, and the supporting effect of the tree transplanting fixing bracket is better.

Since it is closer to the support surface 5 at the other end of the support portion 20, it is a portion susceptible to corrosion; to increase the service life of the support portion 20, the present application defines that the width of the support portion 20 at the end adjacent the support surface 5 is greater than the width of the support portion 20 at the end adjacent the engagement portion 3.

Preferably, the width of the support portion 20 gradually decreases from the end near the support surface 5 to the end near the joint portion 3.

Referring to fig. 12, as an embodiment of the present invention, a swing limiting structure 202 is configured between two sides of the top of the first chute 200 and the connecting plate 341; it can be understood that, in the combined state of the support member 2 and the joint 3, when the support member 2 swings at a certain angle relative to the joint 3, the support portions 20 at both sides of the top of the first chute body 200 can abut against the connection plate 341, so that the swing angle is not increased continuously; under the use scene that the trunk 4 is not banded by the hoop 1, the structure can prevent the hoop 1 from generating excessive play in the length direction of the trunk 4, so that the hoop 1 cannot be separated from a better supporting height.

As an embodiment of the present invention, the supporting portion 20 has a first swing direction and a second swing direction (two-side swing direction) with respect to the joint portion 3, wherein the limit swing angles of the two swing directions are substantially equal.

Preferably, the limit pivot angle a of the first pivot direction is not greater than 30 °.

In a specific application scenario, the transplant personnel can shape and support the tree in the following ways:

selecting a proper number of hoop rods 10 to be connected in sequence, and reserving an opening;

mounting the appropriate amount of the joint 3 on the hoop pole 10 without clasping;

bending a plurality of opening hoop rods 10, and hooping the opening hoop rods on the trunk 4;
