Description

Technical Field

[0001] The invention relates to the technical field of garden protection enclosures, and in particular to a protection enclosure used for forestry and garden greening. Background Art

[0002] The landscaping project is a project to build landscape gardens and green spaces. Landscaping provides people with a good place to rest, engage in cultural entertainment, get close to nature, and satisfy people's desire to return to nature. It is an important measure to protect the ecological environment and improve the urban living environment.

[0003] There are a large number of ornamental green plants in the garden. In order to protect the ornamental plants from being damaged by people, cats and dogs, it is often necessary to set up fences to protect the plants. Ordinary fences can effectively block the crowd, but they do not have good protection for children and small animals. In addition, ordinary guardrails do not have the functions of wind and dust prevention. When encountering strong winds, the ornamental plants are also easily damaged by strong winds. In strong winds, other debris will be blown, which may cause the debris to hit the ornamental plants. Ordinary fences do not have sufficient anti-collision ability and cannot provide good protection for the plants.

[0004] In addition, most traditional fences are cage-shaped or consist of more than two vertical poles, horizontal poles and isolation panels. Since the structures of each garden are different, the installation of the fence is also limited by the actual environment. When assembling, the staff mostly install the vertical poles at the set location first, and then use bolts to connect or assemble through preset docking interfaces. However, the assembly process often results in uneven docking or corner installation. Since the vertical poles have been installed, it is difficult to assemble the horizontal poles. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a protective fence for forestry and landscaping to solve the above problems.

DETAILED DESCRIPTION

[0030] The following will refer to Figures 1 to 7 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0031] First embodiment:

[0032] A protective enclosure for forestry and landscaping, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes more than two vertical poles, and more than two cross bars are installed between adjacent vertical poles. The vertical pole includes a support 1, and more than two mounting bodies 2 are coaxially connected to the support 1. A slot 3 for mounting the end of the cross bar is opened on one side of the mounting body 2; in this embodiment, as Figure 1 As shown, there are multiple mounting bodies 2 on each pillar 1, and the multiple mounting bodies 2 are divided into two mounting groups. For example, the first mounting body 2, the third mounting body 2, and the fifth mounting body 2 from top to bottom form a first mounting group, and the second mounting body 2, the fourth mounting body 2, and the sixth mounting body 2 form a second mounting group. The first mounting group on the pillar 1 corresponds to the first mounting group on the pillar 1 adjacent to its right, and a matching cross bar is installed between the two groups of first mounting groups; the second mounting group on the pillar 1 corresponds to the second mounting group on the pillar 1 adjacent to its left, and a matching cross bar is installed between the two groups of second mounting groups, so as to achieve the purpose of connecting multiple devices to each other.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cross bar includes a first cross beam 4 and a second cross beam 5. A guide rod 6 is fixedly connected to the side of the first cross beam 4 close to the second cross beam 5. More than two positioning holes 8 are provided on the second cross beam 5. The guide rod 6 is slidably connected with the corresponding positioning holes 8. Through the coordinated setting of the guide rod 6 and the positioning holes 8, the distance between the first cross beam 4 and the second cross beam 5 can be adjusted when the second cross beam 5 can slide along the direction of the guide rod 6.

[0034] A spring 30 for buffering is installed between the first crossbeam 4 and the second crossbeam 5, and an outer panel 9 and an inner panel 10 are installed on the first crossbeam 4 and the second crossbeam 5, respectively. In this embodiment, the outer panel 9 and the inner panel 10 are respectively installed on the first crossbeam 4 and the second crossbeam 5 by bolt connection, so that they are detachable. The outer panel 9 can be made of transparent materials such as plastic. When the outer panel 9 or the inner panel 10 is damaged, it is convenient to replace the outer panel 9 or the inner panel 10; the device in this embodiment is provided with two layers of panels, which has stronger impact resistance, and a cavity is left between the outer panel 9 and the inner panel 10, which can improve the sound insulation effect of the device; through the coordination of the outer panel 9, the inner panel 10 and the spring 30, when an external object (it can also be a person, and the present embodiment takes the impact object as an example) accidentally hits the outer panel 9, under the influence of the impact force, the first crossbeam 4 moves close to the second crossbeam 5, that is, the outer panel 9 moves close to the inner panel 10, and the spring 30 is compressed for buffering, which can reduce the impact force on the device and the impact object.

[0035] like Figure 2 , Figure 3 As shown, a damping mechanism is provided on the pillar 1 below the mounting body 2, a guide ring 11 is provided on the top of the damping mechanism, a locking ring is slidably fitted on the guide ring 11, and the stop portion of the locking ring is engaged with the receiving portion of the mounting body 2; the damping mechanism includes a support body 16 fixedly connected to the pillar 1, a rotating drum 17 is coaxially rotatably connected to the pillar 1, the top of the support body 16 is rotatably connected to the bottom of the rotating drum 17, a torsion spring 18 is installed between the inner top wall of the rotating drum 17 and the top of the support body 16, when the rotating drum 17 rotates forward, the torsion spring 18 accumulates force, and the bottom of the guide ring 11 is fixedly connected to the top of the rotating drum 17.

[0036] The locking ring includes a sleeve 19 slidably arranged on the guide ring 11, and the outer surface of the guide ring 11 is set to an elliptical shape, so that the sleeve 19 can only perform lifting and lowering movements on the guide ring 11; an elastic block 20 is installed between the rotating cylinder 17 and the sleeve 19, and the top of the sleeve 19 is fixedly connected to the limiting protrusion 21, and the bottom of the mounting body 2 is provided with more than two limiting grooves 22. When the limiting protrusion 21 is in an engaged state with the limiting groove 22, when the mounting body 2 rotates, the sleeve 19 rotates synchronously with the mounting body 2 When the sleeve 19 is held and moved downward, the limiting protrusion 21 is disengaged from the limiting groove 22, and the elastic block 20 is compressed to store force, and the mounting body 2 is no longer linked to the sleeve 19; when the sleeve 19 is released, the elastic block 20 is unfolded and pushes against the sleeve 19 to rise, and the limiting protrusion 21 and the limiting groove 22 are automatically engaged; the outer surface of the sleeve 19 is provided with an anti-skid layer 26, and the anti-skid layer 26 increases the friction force through the setting of the anti-skid layer 26, which is beneficial for the user to control the sleeve 19 to move downward.

[0037] like Figure 4 and Figure 5As shown, a screw rod 7 is fixedly connected to one side of the first cross beam 4 close to the second cross beam 5, and the screw rod 7 passes through the corresponding positioning hole 8. The guide rod 6 and one end of the screw rod 7 passing through the positioning hole 8 are fixedly connected to a limiting cap 27. A nut 28 is threadedly passed through the screw rod 7, and the nut 28 is located between the second cross beam 5 and the limiting cap 27; when the nut 28 is rotated, the nut 28 moves closer to or away from the first cross beam 4, and then cooperates with the setting of the spring 30 to realize the adjustment of the distance between the first cross beam 4 and the second cross beam 5.

[0038] like Figure 1 As shown, the bottom end of the pillar 1 is fixedly connected with a mounting base 29, and the mounting base 29 is connected to the external mounting base by bolts. A lighting lamp 15 is installed at the top of the pillar 1. The lighting lamp 15 has a built-in light sensing system, which can sense the light intensity of the surrounding environment. When night falls (the ambient light becomes dim), the lighting lamp 15 will automatically light up. This is the prior art and will not be elaborated on. Through the setting of the lighting lamp 15, the fence can be made more conspicuous at night and remind passers-by, effectively reducing accidents caused by unclear vision and increasing the viewing effect of the garden.

[0039] When the device in this embodiment is installed, Figure 1 and Figure 2 As shown, the support 1 is first installed at a set location through the installation base 29. At this time, depending on the installation location (such as a corner), if the direction of the slot 3 needs to be adjusted, the corresponding sleeve 19 is moved downward to disengage the installation body 2 from the sleeve 19, and then the installation body 2 is rotated to adjust the direction of the slot 3, so that the device can be suitable for different installation locations.

[0040] In the initial state, if Figure 5 and Figure 6 As shown, the nut 28 is in a locked state, at which time the distance between the first beam 4 and the second beam 5 is the smallest, which is conducive to the storage of the first beam 4 and the second beam 5 before installation and convenient for the staff to transport the first beam 4 and the second beam 5 to the installation site; when the device is installed, Figure 6 As shown, the two slots 3 are slightly tilted relative to each other (ie, the two slots 3 are not aligned), and the first crossbeam 4 and the second crossbeam 5 are placed in the two slots 3 in an inclined state. Figure 4 , Figure 5 and Figure 7 As shown, the mounting body 2 is then rotated to adjust the position of the slot 3 and align the two slots 3; finally, the nut 28 is rotated and moved away from the first cross beam 4, and the first cross beam 4 moves away from the second cross beam 5 under the action of the pressing force of the spring 30, and finally the first cross beam 4 and the second cross beam 5 are respectively pressed against the two sides of the inner wall of the slot 3, thereby realizing the rapid installation of the first cross beam 4 and the second cross beam 5.

[0041] Compared with traditional enclosures assembled through bolt connections or preset docking interfaces, this device has higher installation applicability, will not cause the situation of uneven docking points that are difficult to assemble, and the installation speed of this device is faster.

[0042] During the use of the device, if Figure 1-Figure 4 As shown, when the outer panel 9 is hit by an external object, the outer panel 9 moves toward the inner panel 10 (at this time, the limit protrusion 21 and the limit groove 22 are in an interlocking state, and under the torsional resistance of the torsion spring 18, the mounting body 2 will not rotate at this time), and at the same time, the first cross beam 4 moves close to the second cross beam 5, and the spring 30 is compressed, thereby achieving buffering of the impact force.

[0043] If the impact force applied to the outer panel 9 is large, after the first crossbeam 4 moves to the limit close to the second crossbeam 5, the second crossbeam 5 presses against the inner wall of the slot 3 and causes the mounting body 2 to rotate. Since the limiting protrusion 21 and the limiting groove 22 are in an engaged state, the sleeve 19 rotates with the mounting body 2, and the guide ring 11 and the rotating cylinder 17 rotate synchronously with the sleeve 19, compressing the torsion spring 18 and further buffering the impact force.

[0044] Second embodiment:

[0045] Based on the first embodiment, Figure 2 As shown, a rope wheel 12 is rotatably connected to the inside of the locking ring on the pillar 1, a rope 13 is wound around the rope wheel 12, and the outer end of the rope 13 is detachably connected to the second crossbeam 5; a push bar 14 is fixedly connected to the rope wheel 12, and the push bar 14 cooperates with the locking ring drive.

[0046] like Figure 2 and Figure 3 As shown, a stopper 23 is fixedly connected to the inner bottom wall of the sleeve 19, and the push bar 14 matches the stopper 23. When rotating around the rope wheel 12, the push bar 14 pushes against the stopper 23 to rotate the sleeve 19. The push bar 14 is a metal bar, and the metal bar has a certain flexibility, that is, the push bar 14 is deformable.

[0047] A rope threading groove 31 is provided on the sleeve 19, the outer end of the rope 13 passes through the rope threading groove 31 and the end thereof is fixedly connected to the connecting ring 24, and a hook 25 is installed on the second crossbeam 5, and the hook 25 is detachably connected to the connecting ring 24. When the device in this embodiment is installed, based on the first embodiment, after the first crossbeam 4 and the second crossbeam 5 are installed, the hook 25 is connected to the connecting ring 24.

[0048] When the device in this embodiment is hit by a foreign object and the impact is large, such as Figure 1-Figure 4As shown, after two bufferings by the spring 30 and the torsion spring 18 according to the first embodiment, the impact force is still large, causing the first beam 4 and the second beam 5 to be disengaged from the slot 3, and the rope 13 to be pulled out. At this time, the outer panel 9 can intercept the impactor to gradually reduce the impact force of the impactor.

[0049] It is worth noting that during the process of the rope 13 being pulled out, the rope winding wheel 12 is driven to rotate, and the push bar 14 rotates synchronously with the rope winding wheel 12. When the push bar 14 rotates to the top stop block 23, the rope winding wheel 12 continues to rotate, which will drive the sleeve 19 to rotate, and the rotating drum 17 rotates to compress the torsion spring 18 to store force.

[0050] It should be noted that as the rope winding wheel 12 rotates, the compression degree of the torsion spring 18 gradually increases, that is, the compression resistance gradually increases (affected by the reaction force, the push bar 14 gradually deforms), which increases the interception force of the outer panel 9 on the impact object. When the deformation amplitude of the push bar 14 increases to the point where it cannot resist the block 23, the torsion spring 18 releases the force and causes the rotating drum 17 to rotate in the opposite direction, and the sleeve 19 resets with the block 23.

[0051] It is worth noting that the buffering time period starts when the push bar 14 abuts against the stopper 23 to rotate the sleeve 19 and when the push bar 14 fails to abut against the stopper 23, and the buffering force of the buffering time period tends to increase gradually.

[0052] During the process of pulling out the rope 13, as the rope winding wheel 12 continues to rotate, the pushing bar 14 intermittently pushes the block 23 to intermittently compress the torsion spring 18 (the sleeve 19 continuously rotates back and forth intermittently, and the rotation angle is set between 45 degrees and 180 degrees. It should be noted that through the setting of the rope threading groove 31, the rotation of the sleeve 19 will not affect the withdrawal of the rope 13), so that the intercepting force of the outer panel 9 on the impact object increases and decreases intermittently, which improves the interception effect and can prevent the torsion spring 18 from being damaged due to excessive compression force.

[0053] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0054] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
