Description

Technical Field

[0001] The invention relates to a support for trees. Background Art

[0002] Trees are usually planted on both sides of the road. On the one hand, trees play a role in beautification and decoration, and on the other hand, they can also play a certain role in purifying the air. There are many newly transplanted trees on both sides of the road. At this time, the root system of the trees is not well developed, the trunk is thin, and it is easy to fall over. Therefore, brackets are usually configured to support the trees.

[0003] A relatively simple support is to set a support pad around the trunk, and then one end of the support rod is supported on the support pad, and the other end is supported on the ground. As the tree grows, the original support structure may no longer be suitable. For example, as the tree grows taller, the support pad moves upward, and the force on the support rod decreases, resulting in a weakened support effect; the support pad set around will also limit the growth of the trunk in the diameter direction.

[0004] In addition, the tree trunks need to be painted with limestone paint for protection, but the painting work is generally done entirely by hand, which is laborious and time-consuming, and the quality of the painting is difficult to guarantee. Summary of the invention

[0005] In view of the above-mentioned defects of the prior art, the present invention provides an adaptive tree stand to solve the problem that the stand is difficult to meet the requirements of changing the supporting state as the tree grows.

[0006] The technical solution of the present invention is as follows: an adaptive tree stand comprises a pair of support rings and a plurality of support legs, the support rings are connected by a locking structure, the upper ends of the support legs are connected to the support rings, the locking structure comprises a locking tongue and a bayonet respectively arranged on the two support rings, the locking tongue is provided with a sliding locking portion, the sliding locking portion is connected to the locking tongue by an elastic member, the bayonet is used to plug the sliding locking portion and keep the sliding locking portion in the bayonet, when the support ring is subjected to force and expands outward, the elastic member is deformed to change the position of the sliding locking portion and the locking tongue to adjust the distance between the two support rings, the support leg comprises an upper rod body, a lower rod body and an elastic telescopic rod, the upper rod body is connected to the support ring, the lower rod body is hinged to the lower end of the upper rod body, the two ends of the elastic telescopic rod are respectively connected to the upper rod body and the lower rod body and keep in a compressed state, and the upper rod body, the lower rod body and the elastic telescopic rod form a triangular state.

[0007] Furthermore, in order to facilitate the installation of the support ring on the tree trunk, one end of the two support rings is hinged, and the other end is provided with the lock structure. In this way, only one side of the lock needs to be operated to sleeve the support ring on the tree trunk.

[0008] Furthermore, the bayonet includes a slot interface, and locking blocks are connected to the two sides of the slot interface through the bayonet elastic member, and a side of the locking block facing the entrance end of the slot interface is an inclined surface or an arc surface, and the sliding locking portion is set to be wedge-shaped. By utilizing the cooperation between the wedge and the inclined surface, the lock tongue can be directly inserted into the bayonet when locking, and the installation is quick.

[0009] Furthermore, in order to reduce the occurrence of the sliding locking part getting stuck in the bayonet, the lock tongue is hinged to the support ring. When the support ring is opened, the lock tongue can rotate to a certain angle so that the direction of the lock tongue is always parallel to the insertion direction of the bayonet.

[0010] Furthermore, the upper rod body and / or the lower rod body are provided with a plurality of pin connection grooves, and the ends of the elastic telescopic rods are provided with pin joints, and the pin joints are placed in the pin connection grooves and connected with pins. According to the height of the ground at the supporting position and the distance of the supporting point, the connection position of the elastic telescopic rod and the upper rod body and / or the lower rod body can be appropriately changed, thereby achieving a suitable initial supporting force.

[0011] Furthermore, an elastic gasket is provided on the inner side of the support ring.

[0012] Furthermore, in order to solve the problem of time-consuming and labor-intensive manual lime painting, the support ring is provided with a plurality of axially arranged connecting rods, the connecting rods are provided with nozzles, the nozzles are connected with an infusion tube, and the infusion tube forms an access port on the support ring. When lime painting is required, the worker carries a portable lime pump to provide limestone paint, connects the lime pump outlet with the access port, and sprays the limestone paint on the tree trunk through the nozzle, which saves manpower and is highly efficient.

[0013] Furthermore, the nozzle is hinged to the connecting rod, and a lifting rod is also connected to the nozzle, and the lifting rod controls the up and down angle of the nozzle when it moves. By changing the angle of the nozzle, a wider range of tree trunks can be covered, and the number of nozzles to be set can be reduced.

[0014] Furthermore, the support ring is provided with a pressing ring matched with the support ring, the pressing ring is provided with a guide groove, the support ring is clamped in the guide groove, a reset elastic member is provided between the bottom surface of the guide groove and the support ring, and the connecting rod is connected to the pressing ring. The rotation of multiple nozzles is synchronously controlled by the pressing ring, so the spraying effect is better and the efficiency is higher.

[0015] Furthermore, the nozzle is a fan-shaped nozzle.

[0016] The advantages of the technical solution provided by the present invention are:

[0017] The present invention utilizes the movement of the sliding locking part, and can automatically adjust the spacing of the support rings in the locked state to adapt to the growth of trees. The upper rod body, the lower rod body and the elastic telescopic rod forming a triangle are used as support legs. The support legs have a certain elastic force and the support angle can be adjusted, which can adapt to the support of tree trunks with different inclination angles and uneven ground. A limestone paint spraying channel is set on the bracket, which is convenient for workers to quickly complete the spraying operation of the tree trunk, which is efficient and saves manpower.

[0026] The present invention is further described below in conjunction with examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading this description, various equivalent modifications to this description by those skilled in the art fall within the scope defined by the claims attached to this application.

[0027] Example 1, please refer to Figure 1 As shown, the adaptive tree stand involved in this embodiment includes a pair of first support rings 1 and second support rings 2, both of which are semicircular. The first support ring 1 and the second support ring 2 both have rigid outer rings, and elastic washers 3 are arranged inside the outer rings. When the first support ring 1 and the second support ring 2 are used to clamp the tree trunk, the elastic washers 3 act as a buffer to prevent the rigid outer rings from directly contacting the bark, thereby avoiding long-term friction and damaging the bark.

[0028] The first support ring 1 and the second support ring 2 are connected at one end by a hinge, so that the two can rotate. The other end of the first support ring 1 is provided with a lock tongue 4, and the other end of the second support ring 2 is a bayonet 5 that cooperates with the lock. The lock tongue 4 and the bayonet 5 form a lock structure for locking. Figure 2 , Figure 3 As shown, the root of the lock tongue 4 is hinged with the first support ring 1, and the head end of the lock tongue 4 can swing at a certain angle. The front part of the lock tongue 4 is provided with a sliding locking part 6 that can move along the front and rear direction of the lock tongue 4, and an elastic member is provided between the front end of the sliding locking part 6 and the lock tongue 4. In this embodiment, the front part of the lock tongue 4 is provided with a hole 7 that passes through horizontally, and the sliding locking part 6 is arranged in the hole 7. The upper and lower ends of the sliding locking part 6 form a sliding fit with the lock tongue 4, and a spring 8 is connected between the front end of the sliding locking part 6 and the lock tongue 4. When the spring 8 is in the initial state, the sliding locking part 6 is close to the rear wall position of the through hole 7 of the lock tongue 4. In other words, the spring 8 can be compressed by pushing the sliding locking part 6 to move toward the head end of the lock tongue 4. The sliding locking part 6 is wedge-shaped with a narrow front end and a wide rear end. The structure of the bayonet 5 is as follows, including a slot opening 9, the width of which is slightly larger than the width of the lock tongue 4, so that when the first support ring 1 and the second support ring 2 are locked or separated, the lock tongue 4 can be easily removed from the slot opening 9 by rotating it without getting stuck. The purpose of the bayonet 5 is to lock the sliding locking portion 6 after the lock tongue 4 is inserted to prevent the lock tongue 4 from being removed from the bayonet 5, so the two sides of the slot opening 9 are connected with locking blocks 10 through the bayonet 5 elastic member, and the specific locking blocks 10 are arranged in the width direction of the slot opening 9 and connected to the second support ring 2 through the bayonet spring 11. The side of the locking block 10 facing the entrance end of the slot opening 9 is an inclined surface or an arc surface. During installation, as the lock tongue 4 is inserted into the slot opening 9, the front end surface of the wedge-shaped structure of the sliding locking portion 6 cooperates with the side of the locking block 10 facing the entrance end of the slot opening 9, pushing the locking block 10 to both sides of the slot opening 9 and compressing the bayonet spring 11. After the locking block 10 passes over the widest part of the rear end of the sliding locking portion 6, the bayonet spring 11 causes the locking block 10 to close to the middle, completing the locking of the sliding locking portion 6. The wedge and the inclined surface are used together for locking, which is quick to install. Please combine Figure 1As shown, the top of the locking block 10 extends from the second support ring 2 to form an operating portion 10a. When unlocking is required, the locking block 10 can be separated to both sides through the operating portion 10a, so that the lock tongue 4 can be pulled out from the slot opening 9. During the growth of the tree, the trunk diameter increases, that is, it is necessary to adjust the distance between the first support ring 1 and the second support ring 2. Under the external support effect of the trunk on the first support ring 1 and the second support ring 2, the lock tongue 4 tends to be pulled out from the slot opening 9. Due to the obstruction of the locking block 10, the sliding locking portion 6 cannot move, and the lock tongue 4 can gradually move backwards and compress the spring 8 at the front end of the sliding locking portion 6, so as to adapt to the thickening of the trunk diameter caused by the growth of the tree.

[0029] Please combine Figure 1 , Figure 4 As shown, two support legs 12 are respectively installed on the first support ring 1 and the second support ring 2. In this embodiment, in order to facilitate the transportation of the bracket, the support legs 12 are separated from the first support ring 1 and the second support ring 2, and then combined during installation. The support legs 12 can also be directly fixed to the first support ring 1 and the second support ring 2 by bolts, welding, etc. The outer ring wall surface of the first support ring 1 and the second support ring 2 is provided with a plug-in groove 13, and the groove walls on both sides of the plug-in groove 13 are serrated. The serrated structure 13a has an inclined surface on one side facing the opening of the plug-in groove 13, and the other side is a plane. Long grooves 13b are provided on the groove walls on both sides of the plug-in groove 13. As shown Figure 5 As shown, the support leg 12 is composed of three parts, namely, an upper rod body 121, a lower rod body 122 and an elastic telescopic rod 123. Laterally telescopic plug-in blocks 121a are arranged on both sides of the upper end of the upper rod body 121. The upper end surface of the plug-in block 121a is an inclined surface or an arc surface, and the lower end surface is a plane. The plug-in block 121a can move laterally into the upper rod body 121 under the pressing pressure. When connecting the support leg 12, align the upper end of the upper rod body 121 with the plug-in slot 13, align the two sides of the plug-in block 121a with the long slots 13b, insert the upper rod body 121 upward, and the plug-in block 121a and the serrated structure 13a in the plug-in slot 13 cooperate and lock. When it needs to be removed, press the plug-in block 121a to move it into the upper rod body 121, and then the upper rod body 121 can be pulled out.

[0030] The lower rod 122 is hinged to the lower end of the upper rod 121, the upper end of the elastic telescopic rod 123 is hinged to the middle of the upper rod 121, a plurality of pin-joining grooves 122a of different heights are provided on the lower rod 122, a T-shaped pin joint 123a is provided at the lower end of the elastic telescopic rod 123, the T-shaped pin joint 123a is placed in the pin-joining groove 122a, and then the lower rod 122 and the elastic telescopic rod 123 are connected by pins. After the first support ring 1 and the second support ring 2 are installed on the tree trunk, the upper rod 121 is connected to the first support ring 1 and the second support ring 2, and then the corresponding lower rod 122 is supported on the bottom surface. According to the terrain and the growth trend of the tree trunk, the pin-joining grooves 122a at different heights on the lower rod body 122 are selected to connect the elastic telescopic rod 123 and the lower rod body 122, so that the upper rod body 121, the lower rod body 122 and the elastic telescopic rod 123 form a triangle shape, and at the same time, different initial elastic forces of the elastic telescopic rod 123 are obtained. The pre-tightening force provided by the elastic telescopic rod 123 ensures that the lower rod body 122 can be closely attached to the ground, thereby achieving a higher supporting effect. At the same time, when encountering bad weather, the extension and retraction of the elastic telescopic rod 123 also plays a buffering role.

[0031] Embodiment 2, as Figure 6 As shown, the adaptive tree support involved in this embodiment is based on the embodiment 1 and further adds a spraying mechanism of limestone paint (white paint for tree protection) to replace manual spraying and improve efficiency. The spraying mechanism includes a nozzle 14, and the nozzle 14 is installed on a connecting rod 15. The connecting rod 15 is vertically arranged and fixed on the first support ring 1 and the second support ring 2 in the axial direction of the first support ring 1 and the second support ring 2. The connecting rod 15 can be set as a hollow structure to form a circulation channel for the paint. In addition, an infusion tube 16 can be set on the inner side of the outer circle of the first support ring 1 and the second support ring 2. The infusion tube 16 forms an access port 17 at the top of the outer circle of the first support ring 1 and the second support ring 2, thereby forming a complete passage from the access port 17 to the infusion tube 16, then to the connecting rod 15 and finally to the nozzle 14. When white paint spraying is required, the worker can directly carry the spray pump and connect the spray pump interface to the access port 17 of the first support ring 1 and the second support ring 2, so as to use the nozzle 14 on the bracket to complete the rapid spraying of the tree trunk. The spraying effect depends on the setting of the nozzle 14 and the position of the connecting rod 15. Therefore, the nozzle 14 can use a fan-shaped nozzle 14 to increase the lateral spraying area. At the same time, a plurality of connecting rods 15 are provided, distributed in the axial direction of the trunk, and a single connecting rod 15 can also be provided with multiple nozzles 14 to meet the requirements.

[0032] As a further improvement, please combine Figure 7 , Figure 8As shown, in order to reduce the number of nozzles 14 but ensure the spraying range, the nozzle 14 is hinged with the connecting rod 15, and the nozzle 14 is connected to the flow channel in the connecting rod 15 through a hose. A lifting rod 18 is also connected to the nozzle 14, and a pressing ring 19 that cooperates with the first support ring 1 and the second support ring 2 is provided on the first support ring 1 and the second support ring 2. The pressing ring 19 is provided with a guide groove 19a for clamping on the first support ring 1 and the second support ring 2. A reset elastic member is provided between the bottom surface of the guide groove 19a and the first support ring 1 and the second support ring 2. The reset elastic member is a reset spring 20. By pressing the pressing ring 19, the lifting rod 18 can be driven to move up and down, thereby controlling the up and down angle of the nozzle 14. By changing the angle of the nozzle 14, a larger range of tree trunks can be sprayed, and these nozzles 14 can be controlled synchronously, with better spraying effect and higher efficiency.
