[0031] First Embodiment

[0032] For the problems actually encountered by gardeners, please refer to Figures 1-4 , this embodiment provides an anti-overturning telescopic fence, which includes an anti-overturning telescopic fence assembly and a fence support frame arranged at the lower part of the anti-overturning telescopic fence assembly. The anti-overturning telescopic fence assembly can extend and retract a shapeable net, so as to customize the enclosed warning range and prevent the warning fence from knocking off flowers and young buds.

[0033] Specifically, the anti-overturning telescopic fence assembly includes a winding drum 110, a winding shaft 120, a winding disc 130, and a telescopic net 140. A vertical strip-shaped opening 111 is formed on the side wall of the winding drum 110 for the telescopic net 140 to be drawn out and retracted. A strip-shaped magnet 112 is arranged on one side of the strip-shaped opening 111 for fixing the strip-shaped block at the strip-shaped opening 111 during final retraction. A strip-shaped slot 113 is also arranged on the winding drum 110 on the side opposite to the strip-shaped opening 111 for fixing after the strip-shaped block 141 of the telescopic net 140 is snapped into the strip-shaped slot 113.

[0034] Bearings 114 are fixed at the upper and lower ends of the winding drum 110 respectively. The winding shaft 120 passes through the winding drum 110 and the bearings 114 and is limited and fixed by the bearings 114. The outer ring of the bearing 114 is fixedly connected to the winding drum 110, and the inner ring of the bearing 114 is connected to the winding shaft 120, so that the winding shaft 120 can rotate stably relative to the winding drum 110, and thus the telescopic net 140 can complete the free drawing and retracting work.

[0035] The take-up reel 130 is fixedly arranged inside the take-up cylinder 110 and is located inside the bearing 114. The take-up shaft 120 penetrates through the take-up reel 130 and is rotatable relative to the take-up reel 130. An annular magnet 131 is arranged on the outer ring of the take-up reel 130. The diameter of the central hole of the take-up reel 130 is larger than the diameter of the take-up shaft 120, so that the take-up reel 130 will not be affected when the take-up shaft 120 rotates. An annular magnet 131 is arranged on the outer ring of the take-up reel 130, so that during the take-up process of the shrinkage net, the upper and lower wide surfaces can be stretched under the attraction of the annular magnet 131, thereby ensuring that the shrinkage net is neatly stored.

[0036] Specifically, the structure of the telescopic net 140 is as follows: One narrow side of the telescopic net 140 is fixedly connected to the take-up shaft 120, and a strip-shaped clamping block 141 is arranged on the other narrow side of the telescopic net 140 for clamping into the strip-shaped clamping groove 113 when the telescopic net 140 is pulled out. The strip-shaped clamping block 141 can be adsorbed to the strip-shaped magnet 112. The structure of the strip-shaped clamping block 141 can be a block partially made of iron, for example, only an iron strip is arranged on one side surface of the strip-shaped clamping block 141, or an iron strip is arranged in the middle of the strip-shaped clamping block 141. The strip-shaped clamping block 141 is integrally made of a relatively light plastic, so as to reduce the weight of the strip-shaped clamping block 141.

[0037] Edge strips 142 are arranged on the two wide sides of the telescopic net 140, and a metal shaping hose 143 is arranged inside the edge strips 142. The structure of the metal shaping hose 143 adopts the existing technology, and an ultra-fine silica gel-coated universal metal shaping hose 143 is used, which is often used for shaping products such as neckband earphones and has the characteristics of being able to be bent and shaped arbitrarily, supporting objects, and making 360-degree non-fixed direction changes.

[0038] The middle part of the telescopic net 140 is a rectangular rope net 144, that is, the middle part is a mesh structure. In this embodiment, a slope protection net that is inexpensive and strong and durable is adopted. It can prevent people from drilling into the repair area, and at the same time, the mesh structure prevents it from being blown down by the wind and has the characteristic of anti-overturning.

[0039] In this embodiment, two take-up methods are provided. One is a manual take-up method, and the cost of the fence is low; the other is an electric take-up method, and the fence is taken up quickly.

[0040] Specifically, when the manual take-up mode is adopted; a hexagonal groove is also arranged at the upper center of the take-up shaft 120. The anti-overturning telescopic fence further includes a take-up handle 121. The take-up handle 121 is Z-shaped. The first vertical section of the take-up handle 121 is a hexagonal column structure that matches the shape and size of the hexagonal groove; the horizontal section of the take-up handle 121 is a connecting section. A handle is arranged on the second vertical section of the take-up handle 121. The first vertical section and the second vertical section are respectively located at both ends of the horizontal section and face in opposite directions.

[0041] The take-up reel 110 is also provided with a storage groove or a storage box for storing the handle. When the take-up operation needs to be performed, the handle is taken out, assembled in the hexagonal groove, and rotated to smoothly store the retractable net 140 into the take-up reel 110.

[0042] When the electric take-up mode is adopted, the anti-overturning retractable fence includes an electric take-up part 150, and the electric take-up part 150 includes: an electric take-up box 151, a micro motor 152, a power supply 153 and a controller 154. The cross-sectional shape of the electric take-up box 151 is the same as that of the take-up reel 110 to ensure overall consistency, and the inside of the electric take-up box 151 is open with a large storage space, which can assemble the micro motor 152, the power supply 153, the controller 154, etc. inside; the power output end of the micro motor 152 is connected to the upper part of the take-up shaft 120, and is used to transmit the output torque to the take-up shaft 120, so that the take-up shaft 120 rotates quickly, so as to achieve the take-up effect; the power supply 153 is arranged in the electric take-up box 151, and in this embodiment, the power supply 153 can use a battery or a rechargeable battery; the controller 154 is arranged in the electric take-up box 151 and is electrically connected to the power supply 153 and the controller 154. A key switch is arranged on the controller 154. When the switch is started, the retractable net 140 can be automatically taken up.

[0043] The fence support frame is fixedly arranged at the lower part of the take-up reel 110. Specifically, the fence support frame includes: a support main pipe 210 and support sub-pipes 220 arranged around the support main pipe 210. In order to ensure the fence support effect and reduce the harm to lawns, etc., the fence support frame in this embodiment is composed of a support main pipe 210 and four support sub-pipes 220.

[0044] A sharp part 211 is arranged at the lower part of the support main pipe 210 for inserting the fence into the ground; a hinged platform 212 is arranged in the middle of the support main pipe 210, and hinged seats 213 are arranged on the four sides of the hinged platform 212; 4 support sub-pipes 220 are respectively arranged on the telescopic hinged platforms 212 on the four sides and are hinged to the hinged seats 213. Compared with the traditional single insertion column, in this embodiment, due to the addition of 4 support sub-pipes 220, the diameter of the support main pipe 210 can be reduced, thereby reducing the harm to the lawn.

[0045] Specifically, the supporting main pipe 210 includes a fixed main pipe 214 and a telescopic pipe 215. The top of the fixed main pipe 214 is fixedly connected to the winding drum 110. A guide column 216 is suspended from the top of the inner cylinder of the fixed main pipe 214. The lower end of the guide column 216 is provided with an anti-slip ring 217. The bottom outer ring of the fixed main pipe 214 is provided with a hinged platform 212. The side wall of the fixed main pipe 214 is provided with a linear slide groove 218 and a vertically extending slide groove 218 connected to the linear slide groove 218. The stop groove 219; the telescopic tube 215 is assembled in the fixed main pipe 214 and is sleeved on the guide column 216. The telescopic tube 215 can be partially stored or extended to the outside of the fixed main pipe 214. The side wall of the telescopic tube 215 is fixed with a toggle member 201, and the toggle member 201 passes through the outside of the linear slide groove 218; a spring 202 is provided on the top of the telescopic tube 215, and the spring 202 is sleeved on the guide column 216, and the other end is connected to the top of the inner cylinder of the fixed main pipe 214.

[0046] The method of use is: when the support main pipe 210 needs to be inserted into the ground, grab the winding drum 110, pull down the toggle member, transfer the toggle member 201 to the horizontal stop groove 219 for fixing, and then expose the thin rod-shaped sharp part. The operation is very simple.

[0047] The supporting sub-tube 220 includes a first hinged portion 221, a first connecting rod 222, a second hinged portion 223 and a reinforcement tip 224, which are arranged in sequence. A magnet is arranged on the inner side of the first connecting rod 222, and the reinforcement tip 224 is an iron tip. The first hinged portion 221 is tight when hinged with the hinge seat 213, and the first connecting rod 222 needs to be pried out by hand. The second hinged portion 223 and the first connecting rod 222 are not tight when hinged, so that when stored, the reinforcement tip 224 can be easily folded toward the first connecting rod 222 or the sharp portion 211 under the action of the second hinged portion 223. Since a magnet is arranged on the inner side of the first connecting rod 222, the magnet can adsorb the reinforcement tip 224, thereby completing the storage work.

[0048] To this end, the second hinged portion 223 and the first connecting rod 222 may be designed as a tight hinged structure, thereby reducing the use of magnets and being able to complete the storage work.

[0049] The usage is:

[0050] When the reinforcing tip 224 is needed for reinforcement, the reinforcing tip 224 is pulled out from the first connecting rod 222 and inserted into the ground for further reinforcement; when the fence does not need to be fixed, the supporting sub-tube 220 is first retracted, and then the toggle member 201 returns to the linear slide groove 218, and the sharp portion 211 retracts rapidly under the action of the spring 202, thereby preventing the tip from being exposed.

[0051] In summary, the new anti-overturning telescopic fence designed by the present utility model is more suitable for garden warning. Its usage method is very simple, which is convenient for garden workers to operate and improves work efficiency.
