Garden isolation fence

Technical Field

The invention belongs to the technical field of isolation protection devices, and particularly relates to a garden isolation fence.

Background

Fences are widely applied in production and life, and comprise garden fences, road fences, municipal fences and the like. In many urban popular private villas and yard fences, wood-made boards are mainly used. The fence post is composed of a fence plate, a transverse band plate and a fence post. The height is generally between 0.5 and 2 meters. The decorative wall has different shapes, generally takes decoration and simple protection as main installation purposes, and is very popular in Europe and America.

Nowadays, in order to protect the natural ecosystem, gardens are more and more built in various cities, and the gardens are diversified, wherein the gardens comprise children and parks, which are commonly called as children parks, and the children and parks are urban professional parks for preschool and school-age children to play games, entertainments, sports activities and culture science popularization education. The purpose of building the children park is to create colorful good conditions for the children, which mainly take outdoor activities, so that the children can contact with the nature during activities, become familiar with the nature, contact scientifically and love scientifically, thereby training the body, increasing the knowledge and leading the children park to grow healthily in the aspects of moral, intelligence and body, and the children park is usually filled with beautiful flowers, grass and the like, in order to protect these flowers, plants and grasses from being trodden on, parks often use fences to separate flower gardens, however, children are always good, and even though the isolation fence is protected, it is difficult to avoid that the children climb on the isolation fence, and even parents hold the children to sit on the isolation fence, the partition fence is deformed and broken frequently due to the operation, and the partition fence is easy to collapse due to the fact that the bottom of the partition fence is prone to incline due to frequent long-time shaking.

The invention has the following beneficial effects:

1. when a child climbs the isolation fence or parents place the child on the bearing plate, the insertion rod at the lower end of the bearing plate can slide towards the insertion pipe under the influence of the weight of the child, so that the bearing plate has certain elasticity, namely, when the bearing plate is stressed, the stressed point can be converted into a plane, so that the possibility of deformation of the bearing plate is greatly reduced, and meanwhile, when the insertion rod slides towards the inside of the insertion pipe, the upper wall of the rubber ball can be driven to move towards the lower end, so that the air pressure in the cavity inside the rubber ball is compressed and finally enters the air pressure groove, when the air pressure in the air pressure groove is increased, the expansion balls at the two ends of the air pressure groove can be expanded, so that the sliding rod at the upper end of the air pressure groove is pushed to slide into the insertion rod, so that the upper wall of the rubber ball can be tightly connected with the lower end of the insertion rod when the bearing plate moves downwards, thereby avoiding the long-time sliding to cause the disconnection of the rubber ball and the inserting rod and the incapability of compressing the air pressure in the rubber ball.

2. When the air pressure in the rubber ball is compressed, certain rebound force can be given to the plug rod, so that the plug rod corresponds to the gravity generated by children, the lower end of the plug rod can be protected, the deformation of the lower end of the plug rod is avoided, when the plug rod moves downwards to a certain degree, a cross opening on a blocking ball at the lower end of the plug rod can be extruded by a triangular cone, high-pressure air in the sealed rubber ball enters a gas gathering groove in a bearing plate through a gas guide hole in the plug rod instantly, the air pressure in the gas gathering groove starts to increase, when the air pressure in the gas gathering groove increases to a certain degree, the extrusion rods at the two ends of the extrusion rods can be pushed to slide towards two sides, and then when the bearing plate moves downwards, the extrusion rods can start to extrude the rubber plate, and simultaneously, because the outer side of the rubber plate is set to be arc-shaped, the extrusion rods can generate intermittent impact force when extruding the outer surface, thereby make the inboard cavity atmospheric pressure of rubber slab can be the discontinuity by the impact extrusion, and then make high pressure gas can be discontinuity by the inside of inputing into mounting groove and telescopic link, thereby it advances ground to make the outer end of telescopic link expand the back to be discontinuous grafting, thereby make when the bearing plate receives in the twinkling of an eye gravity influence the telescopic link be quick impact form get into the soil in, and then realize transient fixed, and disappear when gravity, the telescopic link breaks away from being connected with ground, give ground the certain time and resume, avoid the telescopic link to peg graft for a long time and lead to ground poroid appearing in ground, reduce the joint strength on telescopic link and ground, thereby reduce the stability of erection column and increase its possibility of collapsing.
