Description

Tennis protecting net

Technical Field

The invention relates to a tennis protecting net.

Background

Tennis is a popular sport at present, the sport intensity is high, more balls need to be used during the sport, after the training is finished, the balls on the ground need to be collected, the balls are scattered, the collection is troublesome, and if tennis balls scattered on the ground are trampled during the sport, sportsmen can fall down, so that the tennis is unsafe.

Based on the above problems, it is desirable to provide a tennis net that can better buffer the impact force of tennis balls, reduce the rebound distance of tennis balls, store tennis balls at a high probability, and facilitate collection and arrangement of tennis balls after sports.

Disclosure of Invention

The invention aims to solve the technical problem of providing a tennis protecting net which can better buffer the impact force of tennis balls, reduce the rebound distance of the tennis balls, store the tennis balls at a certain probability and facilitate the collection and arrangement of the tennis balls after the sports is finished.

In order to solve the problems, the invention adopts the following technical scheme:

a tennis protecting net comprises a plurality of bases arranged on the ground, the bases are connected end to end, two sockets are arranged at the top of each base, stand columns are inserted in the sockets, screws are connected between the bases and the stand columns, a plurality of movable sliding sleeves are arranged on the stand columns, protruding blocks are arranged at the front outer walls and the rear outer walls of the sliding sleeves, a first frame and a second frame are matched between the two stand columns through the sliding sleeves, a first screw is matched between the first frame and the protruding block, the first screw penetrates through the sliding sleeves and abuts against the outer walls of the stand columns, a metal net is welded in the first frame, a plurality of fixing holes are symmetrically arranged at two sides of the second frame, a rope body is matched between the two symmetrical fixing holes, two ends of the rope body penetrate through the fixing holes and are fixed after knotting, a gap for passing through tennis balls is formed between two adjacent rope bodies, and the distance between the first frame and the second frame is 10-15 cm.

Preferably, the front side and the rear side of each base are provided with connecting plates, and bolts are matched between every two adjacent bases through the connecting plates.

Preferably, the stand is aluminum alloy stand, the stand is hollow structure, and hollow structure's stand quality is lighter, easily carries, adopts aluminum alloy material simultaneously, has the corrosion resisting property of preferred, when using, can carry out further protection in the outer wall department brush drawing paint of stand.

Preferably, a drain hole is formed on the outer wall of the upright column near the bottom, and water accumulated in the upright column can be drained through the drain hole.

Preferably, threaded holes are uniformly distributed in the bottom of the base, inserting rods for inserting into mud fields are matched through the threaded holes, the inserting rods are conical, threaded parts matched with the threaded holes are arranged on the inserting rods, and the inserting rods are provided with polygonal stressed parts.

Preferably, the rope body is a hemp rope or a nylon rope.

The invention has the beneficial effects that: this device when installation, the rope sets up the one side near the place of sports, when hitting the second frame in the tennis, if take place the contact with the rope, then can cushion the impact force of ball, reduce the reflection distance of ball, avoid the tennis to enter into the place of sports once more, avoid being stepped on by the sportsman, the ball has great possibility to pass two adjacent ropes, then block via the metal mesh, fall in the intermediate layer of rope and metal mesh, be convenient for collect the arrangement to the ball after the motion is ended, the structure of this device is comparatively simple, the cost is comparatively cheap, and is suitable for being generalized to use.
