Embodiment 1
[0015] figure 1 It is a schematic structural diagram of the tennis ball recovery device of the present invention, figure 2 It is a top view of the present invention. exist figure 1 , 2 Among them, the tennis ball recovery device of the present invention includes a universal caster 1, a double-guided extrusion structure, and a fence. The connection relationship is that the shape of the double-guided extrusion structure is a planar quadrilateral frame, and several metal rods 3 are arranged on the frame. The rod forms the guide groove of the tennis ball. The fence includes four uprights 4 and several crossbars 5, and the several crossbars are respectively fixedly connected with the uprights. The lower parts of the four columns are respectively fixedly connected with the four corners of the frame, and the lower ends of the columns are provided with universal casters 1 . The distance between the two end points of the frame 2 on the front side of the frame and the correspondi...

The invention provides a tennis recovery device. A set of double guide and extrusion structure is arranged at the bottom of the recovery device, is a plane quadrangular frame structure, and is provided with a plurality of tennis passing grooves of which the front parts are wider and the rear parts are narrower, wherein the widths of the tennis ball passing grooves are smaller than the diameters of tennis ball; the double guide and extrusion structure is arranged at the bottom of the device in a manner that the front part is higher and the rear part is lower; the height of the front part of the double guide and extrusion structure relative to the ground is greater than the diameter of the tennis, and the height of the rear part of the double guide and extrusion structure relative to the ground is greater than the radius of the tennis. According to the tennis recovery device, the front part of the double guide and extrusion structure is wider and higher, and the rear part of the double guide and extrusion structure is narrower and lower, so that the tennis recovery device is endowed with a function of wedge-shaped guide and extrusion in the width and height directions; the recovery device is simple and practical, and can be used for easily and efficiently recovering a great number of tennis scattered on the ground; when the tennis recovery device passes over the tennis, the tennis ball can be easily recovered.
Description
technical field [0001] The invention belongs to the field of sporting goods, and in particular relates to a tennis ball recovery device, which can recover a large amount of tennis balls scattered on the ground. Background technique [0002] The tennis training process will produce a large number of tennis balls scattered on the court, which need to be recycled during or after the training process. For alleviating the labor load of reclaiming a large amount of tennis balls, some products such as pick-up baskets and ball-picking baskets are available, which utilize the elasticity of tennis balls to recover them by extrusion. This type of product uses the lifting force of the hand to lift the ball picking device, and then press down hard to squeeze the ball into the recycling container. This method avoids the manual action of repeatedly bending over to pick up the ball, but there is a forceful action of lifting and pressing down, especially after recovering more tennis balls,...
