Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 7, the table tennis table is a common table tennis competition and training field, the center of which is a table, and the periphery of which is provided with a back fence I and a side fence II for preventing the table tennis from rolling far. Most of table tennis balls fly to the turning block after being missed, then bounce everywhere and finally scatter everywhere in the field. The athlete picks up the ball back and forth, which wastes time and is also labor-consuming.

The theory of operation of this application, it is main to replace back wall and side wall fender, makes it collect the ball when the ball comes, and can not need to pick up again and directly take when the sportsman needs to use the ball.

As shown in fig. 1 to 6, a ball picking device for table tennis according to the present application is characterized in that: the novel tent comprises a shell 1 consisting of a left side wall 3, a right side wall 3 and a tent plate, wherein the side walls 3 are 1/4 circles, arc edges of the side walls are connected with the tent plate, guide pipes 4 are symmetrically arranged on the left and right outside the side walls, two bead chain wheels 2 are symmetrically arranged on the left and right of the top of the shell 1, two closed bead chains are respectively arranged in the left and right guide pipes 4 in a penetrating manner and are respectively meshed with the left and right bead chain wheels, and the bead chain wheels can drive the bead chains to synchronously rotate when rotating;

the bag also comprises a bag 6 made of elastic material, the top of the bag opening of the bag is fixed on the top of the shell, and the bottom of the bag opening is fixed on a left hanging point 14 and a right hanging point 15 on the left and right bead chains; the bag bottom is fixed on the bottom supporting mechanism and is supported by the bottom supporting mechanism;

in the initial state, the bottom of the bag opening of the bag 6 is tightly attached to the ground so as to enable table tennis balls to enter the bag to the maximum extent, the bottom supporting mechanism is tightly attached to the ground so as to prevent the table tennis balls from rolling out, and in this state, the bag made of elastic materials is in a stretching state;

The key point of the scheme is that the ball collecting bag is provided with an elastic ball collecting bag, a space A for accommodating balls to fly or roll in is arranged, a bag opening is arranged on a movable ball chain, and then the opening and closing of the bag opening are controlled through the rotation of a ball wheel (driven by the ball chain wheel). And because the upper part of the bag opening is fixedly arranged on the shell, when the bag bottom contracts upwards, the bag opening of the final contracted opening is close to the bottom of the shell, namely the height which can be obtained by the athlete without stooping and stretching the hand; simultaneously, because the supporting mechanism makes the bag bottom also promote, whole bag body all promotes, and the space in the bag also because the elastic contraction of bag is space B, makes the ball wherein can conveniently take out.

The ball chain and the ball chain wheel mechanism are transmission mechanisms similar to synchronous belts, but have better usability and lower use requirements, the ball chain is not required to be completely positioned in a plane, and the transmission can be realized as long as certain meshing with the ball chain wheel is ensured, even if the ball chain and the ball chain wheel are not tensioned. However, in this embodiment, to ensure reliable movement of the mechanism, a guide tube is provided to allow reliable movement of the bead chain when a plurality of devices are arranged side by side.

As shown in the figure, the two bead chains form an 'eight' shape, and the bottom of the bag is respectively fixed on the left hanging point and the right hanging point, so that the bag opening is in a contraction and gathering state along with the flowing of the bead chains.

This is because the balls in the bag are originally in a dispersed state, and the bag mouth is contracted, so that the balls can be easily taken out even if they are gathered.

Meanwhile, the ball chain is thin, so that the flying-in of the table tennis ball cannot be influenced, and the table tennis ball can continuously enter due to inertia even if the table tennis ball is collided.

Furthermore, a middle gear 9 is installed at the top of the shell, a side gear 11 is coaxially arranged on each bead chain wheel, and two racks 10 are symmetrically arranged on the circumference and are respectively meshed with the left gear, the middle gear, the right gear and the middle gear at the same time, so that the rotation of the middle gear can drive the two bead chain wheels to rotate at the same time.

The arrangement can drive the chain wheel to rotate only by rotating the rotating wheel when a player needs a ball, and the bag is taken up to a height which can be reached by a spittle hand and then the ball is taken. See the position of the rack in fig. 6.

Further, the housing height is about 1.2 meters.

This is estimated from the height of the average athlete.

Through the arrangement, the bottom supporting mechanism and the ball chain mechanism are linked, when the sportsman operates the runner, the ball chain drives the bag opening to contract, and the n-shaped bottom supporting frame enables the bag bottom to be lifted, so that the table tennis ball can be taken out conveniently.

Due to the arrangement, the bag bottom is not inclined when the table tennis is collected, and the table tennis cannot be poured out.

Further, an upper cover 13 covering the rack mechanism is further provided above the housing, and a ball basket (not shown) is detachably provided above the upper cover.

The typical use method of the scheme is as follows: adopt this device to set up side by side, replace the fender that encloses in figure 7 to collect the table tennis that flies, when needs, operation hand wheel makes the bag promote and close up, with the ball in the bag in the basket, the basket still installs back the upper cover, makes things convenient for the sportsman to take as required.

Furthermore, the middle rotating wheel is also provided with a resetting mechanism which enables the device to return to the initial state from the ball collecting state.

Since the motion of the wheel is only rotational, it can be reset by a simple mechanism such as a spring.

Furthermore, a plurality of the shells, the mechanisms connected with the shells and the bags are arranged in an abutting mode to form a fence surrounding the court.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
