Description

Technical Field

[0001] The utility model relates to the technical field of tree fixing frames, in particular to a tree supporting fixer. Background Art

[0002] At present, urban greening is receiving more and more attention. Major cities are planting a large number of street trees. When the trees are first planted, they are easy to fall over because their roots are small and the root depth is shallow. In order to prevent the newly planted trees from falling over, they need to be supported and fixed around the trees with fixers.

[0003] At present, a Chinese utility model with publication number CN210184074U discloses a greening tree support fixer, including multiple support units, which are used to support trees around the trunk along the circumferential direction. The support unit includes a support plate and a support rod. The top end of the support rod is rotatably connected to the support plate, and the surface of the support plate used to contact the tree trunk is an arc surface. The support rod includes an upper support rod unit and a lower support rod unit. The lower support rod unit can move relative to the upper support rod unit along the length direction of the upper support rod. The top end of the upper support rod unit is used to be rotatably connected to the support plate, and the bottom end of the lower support rod unit is used to contact the ground. A support rod fixing unit is provided at the connection between the upper support rod unit and the lower support rod unit.

[0004] However, the support plate of the existing fixer is easy to slide upward during the process of supporting the support rod, so that the fixer cannot play a good supporting and fixing role on the tree. Utility Model Content

[0005] The utility model aims to provide a tree support fixer, which has the advantage of preventing the fixer from slipping and being able to play a good supporting and fixing role on the tree.

[0006] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0008] Through the above technical scheme, a number of support units are arranged around the tree circumference to support the tree from all sides, making the tree support more stable; the support rod is hinged to the support head, which is convenient for adjusting the support angle between the support rod and the tree; the support surface abuts against the side wall of the tree, and since the upper and lower sides of the support head are arc-shaped side walls, when the support rod is rotated toward the side close to the tree, one end of the support rod contacts the ground, and the supporting force of the support rod is transmitted to the support head and the supporting force is concentrated on the extrusion point, so that the support head squeezes the tree through the extrusion point, and the support head is clamped on the tree. The support rod can stably support and fix the tree and prevent the fixer from slipping.

[0009] In one embodiment of the present invention, a locking hole is provided on the support head below the extrusion point, and a locking belt for clamping the support head on the tree is passed through the locking hole.

[0010] Through the above technical solution, the locking hole is arranged on the support head below the extrusion point, and the locking belt is passed through the locking hole, so that a plurality of support units are locked around the tree.

[0011] In an embodiment of the present invention, a weight-reducing hole is provided on the support head, and the inner wall of the weight-reducing hole is an arc-shaped structure.

[0012] Through the above technical solution, the weight-reducing hole is used to reduce the weight of the support head and reduce the cost, and the inner wall of the weight-reducing hole is an arc-shaped structure, which increases the supporting strength of the support head.

[0013] In an embodiment of the present invention, the width of the weight-reducing hole on the side close to the support surface is smaller than the width of the weight-reducing hole on the side away from the support surface.

[0014] Through the above technical solution, the weight-reducing hole is similar to a triangular structure, ensuring the stability of the support head structure.

[0015] In an embodiment of the present invention, a connecting portion is integrally formed on the support head.

[0016] In one embodiment of the present invention, the support rod comprises a connecting head and a supporting rod, and the connecting head comprises a connecting sleeve and a connecting ear integrally formed on the connecting sleeve;

[0017] The support rod is inserted into the connecting sleeve, and the connecting ear is connected to the connecting part through a connecting shaft.

[0018] Through the above technical solution, the support rod is inserted into the connecting sleeve for easy disassembly and assembly; the connecting ear and the connecting part are connected by a connecting shaft to achieve hinged connection.

[0019] In one embodiment of the present invention, three support units are arranged around the tree at equal angles.

[0020] Through the above technical solution, the three support units are distributed in a triangle around the tree, thereby achieving stable support and fixation of the tree.

[0021] As described above, the tree support and fixer of the utility model has the following beneficial effects:

[0022] The support rod is hinged to the support head to facilitate adjustment of the support angle between the support rod and the tree; the support surface abuts against the side wall of the tree. Since the upper and lower sides of the support head are arc-shaped side walls, when the support rod is rotated toward the side close to the tree, one end of the support rod contacts the ground, and the supporting force of the support rod is transmitted to the support head and the supporting force is concentrated on the extrusion point, so that the support head squeezes the tree through the extrusion point, and the support head is clamped on the tree. The support rod can stably support and fix the tree and prevent the fixer from slipping. BRIEF DESCRIPTION OF THE DRAWINGS
