Description

Technical Field

[0001] The utility model relates to the technical field of garden auxiliary equipment, in particular to an automatic adjustable tree trunk supporting device for sand-proof gardening. Background Art

[0002] With the continuous advancement of science, my country's gardening technology is constantly developing. Trees need to be planted in sand-proof gardens. During the growth of trees, they may be affected by wind and sand and fall down. Therefore, supporting devices are needed to support the trees and keep them in a stable state.

[0003] At present, the existing support devices are generally directly fixed and tightened around the tree when in use. The support height cannot be adjusted and can only be used at a fixed height. As the tree grows, the fixed height support device cannot provide stable support and needs to be adjusted manually, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an automatic adjustable tree trunk support device for sand-proof gardening, so as to solve the problem that the support device in the prior art cannot automatically adjust the support height of garden trees.

[0005] Based on the above purpose, the utility model provides an automatic adjustable tree trunk support device for sand prevention gardening, comprising:

[0006] The protection component includes two arc-shaped support rings, one end of the two support rings are hingedly connected, and the tree trunk is surrounded and fixed in the two butted support rings;

[0007] A support assembly, comprising at least three sleeves for supporting the ground, wherein a support rod is sleeved in the sleeve, and one end of the support rod away from the sleeve is hingedly connected to the support ring, and a rotatable limit clamp is provided on the support rod, and an inner side wall of the sleeve is provided with a rack extending along its length direction;

[0008] In a natural state, the limit clamp is engaged with the rack to prevent the support rod from retracting toward the inside of the sleeve; when the support rod is subjected to a traction force extending relative to the sleeve, the limit clamp is rotated by the rack to release the engaged state.

[0009] Furthermore, the limit clamp is a pawl arranged on the support rod, the rack is a helical rack, the inclination angle of the upper tooth surface of the helical rack is greater than the inclination angle of the lower tooth surface, and in a natural state, the pawl is connected to the rack hook.

[0010] Furthermore, the pawls include at least two pawls spaced apart from each other along the axial direction of the support rod.

[0011] Furthermore, a pivot shaft is constructed on the support rod, and the pawl is rotatably mounted on the pivot shaft. An elastic member is also mounted on the pivot shaft, one end of the elastic member is fixedly connected to the support rod, and the other end abuts against the pawl. The elastic member has an elastic force that drives the pawl to abut against the rack.

[0012] Furthermore, it also includes:

[0013] The fixing assembly comprises a fixing support member hingedly connected to one end of the sleeve away from the support rod, a side of the fixing support member facing away from the sleeve is circumferentially detachably connected with a plurality of pointed cones, and the fixing support member is inserted into the ground through the pointed cones.

[0014] Furthermore, the pointed cone is threadably connected to the fixed support member.

[0015] Furthermore, the protection component also includes:

[0016] A first buffer layer is clamped and connected to the inner side of the support ring;

[0017] The second buffer layer is attached to a side of the second buffer layer away from the support ring, and the hardness of the first buffer layer is greater than the hardness of the second buffer layer.

[0018] Furthermore, a plurality of grooves are arranged at intervals along the circumference of the inner side of the support ring, a protrusion is arranged on the side of the first buffer layer facing the support ring, and when the first buffer layer is attached to the inner side of the support ring, the groove and the protrusion are engaged with each other.

[0019] Furthermore, the first buffer layer is a rubber layer, and the second buffer layer is a buffer cotton layer.

[0020] Furthermore, the two support rings are butt-connected via a connecting piece that passes through both of them, and the connecting piece is an elastic telescopic piece.

[0021] From the above, it can be seen that the automatic adjustable trunk support device for sand-proof gardening provided by the utility model utilizes a protective component to clamp the trunk of the tree. Since the sleeve supports the ground, in a natural state, the limit clamp is clamped with the rack to prevent the support rod from retracting into the sleeve. As the tree grows, the protective component clamped with the trunk moves up with the trunk. At this time, the support rod is pulled relative to the sleeve, and the limit clamp is rotated to release the clamping state, so that the support rod can only extend out of the sleeve but cannot retract into the sleeve, thereby realizing the autonomous adjustment of the trunk height by the support device without manual intervention, which is beneficial to reducing the time and labor cost of supporting the trunk.

[0034] The automatic adjustable tree trunk support device for sand prevention gardening of the present application is described below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, one or more embodiments of the present application provide an automatic adjustable tree trunk support device for sand-proof gardening, which specifically includes a protection component and a support component.

[0036] Among them, the protection component includes two arc-shaped support circles 100, one end of the two support circles 100 is hingedly connected, and the trunk is surrounded and fixed in the two docked support circles 100; the support component includes at least three sleeves 200 for supporting the ground, a support rod 201 is sleeved in the sleeve 200, and the end of the support rod 201 away from the sleeve 200 is hingedly connected to the support circle 100, and a rotatable limit clamp is provided on the support rod 201, and the inner side wall of the sleeve 200 is provided with a rack 205 extending along its length direction; in a natural state, the limit clamp is engaged with the rack 205 to prevent the support rod 201 from retracting into the inside of the sleeve 200; when the support rod 201 is subjected to a traction force extending relative to the sleeve 200, the limit clamp is rotated by the rack 205 to release the engaged state.

[0037] From the above description, it can be seen that the automatic adjustable trunk support device for sand-proof gardening described in the present application utilizes a protective component to clamp the trunk of the tree. Since the sleeve 200 supports the ground, in a natural state, the limit clamp is engaged with the rack 205 to prevent the support rod 201 from retracting into the sleeve 200. As the tree grows, the protective component clamped with the trunk moves up with the trunk. At this time, the support rod 201 is pulled relative to the sleeve 200, and the limit clamp is rotated to release the clamping state, so that the support rod 201 can only extend out of the sleeve 200 but cannot retract into the sleeve 200, thereby realizing the autonomous adjustment of the trunk height by the support device without manual intervention, which is beneficial to reducing the time and labor cost of supporting the trunk.

[0038] like Figure 2 As shown, in some embodiments, the support ring 100 of the protective component is semicircular, and the support ring 100 is made of metal material. One end of the two support rings 100 is hingedly connected, wherein one end of the support ring 100 away from the hinged end 101 protrudes radially outward to form a fixed plate 102, and the fixed plate 102 is provided with a through hole. When the two support rings 100 are rotated to a closed circular shape, a fixed connection is formed by a connecting piece 103 that penetrates the two through the through holes.

[0039] Here, the connector 103 can be an elastic telescopic member. For example, the connector 103 can be a tension spring, and the two ends of the tension spring are respectively constructed with hooks, and the hooks are hooked in the perforations to form a connection between the two support rings 100. Of course, the connector 103 is only used as an example here. As a replaceable embodiment, the connector 103 is a bolt member with a perforation, and a spring is sleeved on the bolt member, and the two ends of the spring are respectively connected to the fixed plate 102. The elastic telescopic member can adapt to the diameter change caused by the natural growth of the tree, so as to avoid excessive tightening of the trunk and affecting the tree. It should be noted that due to the friction between the trunk and the support ring 100, the protective component should move up synchronously with the growth height of the trunk. Therefore, when the two support rings 100 are docked to surround the trunk, the support rings 100 should clamp the trunk as much as possible without damaging the epidermis of the trunk when docking through the connector 103.

[0040] like Figure 3 As shown, in some embodiments, the protection component also includes:

[0041] The first buffer layer 104 is clamped and connected to the inner side of the support ring 100;

[0042] The second buffer layer 105 is attached to a side of the second buffer layer 105 facing away from the support ring 100 . The hardness of the first buffer layer 104 is greater than that of the second buffer layer 105 .

[0043] In the above embodiment, the first buffer layer 104 is a rubber layer, and the second buffer layer 105 is a buffer cotton layer. Here, the buffer cotton layer can be pearl cotton or foam cotton commonly used in the relevant technology. Since the hardness of the first buffer layer 104 is greater than the hardness of the second buffer layer 105, the second buffer layer 105 directly attached to the surface of the trunk can further weaken the degree of pressure on the trunk by the protective component, which is beneficial to protecting the epidermis of the trunk. In addition, since the second buffer layer 105 is a relatively soft buffer material, the first buffer layer 104 also plays a role in supporting and fixing the second buffer layer 105, preventing the problem that the second buffer layer 105 is directly fixed on the support ring 100 and is easily deformed and detached.

[0044] Still Figure 3 As shown, in some embodiments, the inner side of the support ring 100 is provided with a plurality of grooves spaced apart along its circumference, and a protrusion 107 is provided on the side of the first buffer layer 104 facing the support ring 100, and when the first buffer layer 104 is attached to the inner side of the support ring 100, the groove and the protrusion 107 are engaged and snap-fitted.

[0045] In the above embodiment, the first buffer layer 104 and the second buffer layer 105 can be directly bonded and connected, and the support ring 100 and the first buffer layer 104 are snap-fitted through the card slot 106 and the protrusion 107, which can effectively prevent relative displacement between the first buffer layer 104 and the support ring 100 and ensure the fixing effect of the first buffer layer 104 and the support ring 100.

[0046] In some embodiments, Figure 4 As shown, in some embodiments, the limiting clamp on the support assembly is a pawl 202 provided on the support rod 201, and the rack 205 is a helical rack 205, and the inclination angle of the upper tooth surface 203 of the helical rack 205 is greater than the inclination angle of the lower tooth surface 204. In a natural state, the pawl 202 is hookedly connected to the rack 205.

[0047] Reference Figure 4 The directions shown indicate that Figure 4In the embodiment, a certain tooth on the rack 205 has an upper tooth surface 203 and a lower tooth surface 204. In the above embodiment, one end of the pawl 202 is hingedly connected to the support rod 201, and the other end can rotate relative to the support rod 201. In the natural state, the sleeve 200 and the support rod 201 are in an inclined supporting state. At this time, the pawl 202 naturally hangs down under the action of gravity. The inclination angle of the upper tooth surface 203 of the rack 205 is greater than the inclination angle of the lower tooth surface 204. The teeth of the rack 205 are set obliquely upward, and the pawl 202 is limited and clamped between two adjacent teeth of the rack 205. When the tree grows, its height changes, and the protective component moves up synchronously with the growth of the tree. Since the support rod 201 and the support ring 100 are hingedly connected, the support rod 201 is subjected to the pulling force of the support ring 100 and has a tendency to extend relative to the sleeve 200. Since the teeth of the rack 205 are inclined upward, the pawl 202 is guided by the upper tooth surface 203 of the rack 205 to rotate counterclockwise. As the height further changes, the pawl 202 breaks away from the upper tooth surface 203 at this time and droops again due to the action of gravity, and is abutted by the teeth located below to re-form a clamping state.

[0048] In the above embodiment, further, a pivot shaft is configured on the support rod 201, the pawl 202 is rotatably sleeved on the pivot shaft, an elastic member is sleeved on the pivot shaft, one end of the elastic member is fixedly connected to the support rod 201, and the other end abuts against the pawl 202, and the elastic member has an elastic force driving the pawl 202 to abut against the rack 205. Here, the elastic member can be a torsion spring, and the provision of the torsion spring can further enhance the clamping force of the pawl 202 to prevent the pawl 202 from accidentally disengaging from the rack 205.

[0049] It should be noted that, since the trunk of a tree grows slowly, the actual length of the tree does not change significantly, and the state of engagement-disengagement-reengagement of the pawl 202 and the rack 205 is a long-term continuous state switching. In order to further ensure the support stability of the support assembly, the pawl 202 has at least two pawls 202 arranged at intervals along the axial direction of the support rod 201. As an alternative embodiment, the inner side wall of the sleeve 200 is circumferentially arranged with racks 205, and the support rod 201 is provided with two groups of pawls 202 at intervals along its axial direction, and each group of pawls 202 includes two symmetrically arranged on the support rod 201. It is sufficient to ensure that the pawl 202 and the rack 205 are in an engaged state.

[0050] In some embodiments, Figure 1 and Figure 5As shown, the sleeve 200 of the support assembly has four hinged connections spaced circumferentially along the support ring 100. The automatic adjustable tree trunk support device for sand control gardening also includes a fixing assembly, which includes a fixed support member 300 hingedly connected to one end of the sleeve 200 away from the support rod 201, and a plurality of pointed cones 301 are detachably connected to the side of the fixed support member 300 facing away from the sleeve 200 in the circumferential direction, and the fixed support member 300 is inserted into the ground through the pointed cones 301.

[0051] In the above embodiment, one end of each sleeve 200 away from the support rod 201 is hingedly connected to a fixed support member 300, and the pointed cone 301 is threadedly connected to the fixed support member 300. Exemplarily, the pointed cone 301 has a threaded section 302, and the fixed support member 300 is provided with a mounting hole with an opening facing downward, and the mounting hole has an internal threaded section 302, and the pointed cone 301 is threaded into the mounting hole. Providing multiple pointed cones 301 can ensure that a stable and reliable anchoring effect is formed after being inserted into the ground, and prevent the support assembly from shaking when affected by wind and sand, thereby affecting the support effect.

[0052] In some embodiments, a buffer pad 303 is further disposed between the pointed cone 301 and the fixed support member 300 . The provision of the buffer pad 303 can further enhance the support stability after the pointed cone 301 is screwed into the fixed support member 300 .

[0053] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present disclosure (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
