Description

A collection and ejection device under the table tennis table

technical field

The utility model relates to a device for collecting and ejecting table tennis balls, in particular to an under-table collecting and ejecting device for table tennis balls.

Background technique

Playing table tennis is a kind of mass sports, but, often occur the situation that table tennis rolls and falls directly below the table, especially when carrying out table tennis training. If the table tennis ball is near the periphery under the table, you can bend down and pick it up for reuse. If the table tennis ball is near the center of the table, you need to use a long rod tool to take out the table tennis ball. Even if there is a special mesh ball picker, it is time-consuming and laborious.

Contents of the invention

The utility model proposes an under-table table tennis collection and ejection device, the purpose of which is to solve the problem that it is inconvenient to pick up under-table table tennis balls.

In order to solve the above technical problems, the technical solution of the present invention is as follows: a collection and ejection device under the table tennis table, which is characterized in that: it includes a collection device and an ejection device that can be fixed under the table; the collection device includes a central support frame, a central The top of the support frame is connected with one end of the four support rods, and the other ends of the four support rods are connected with the rectangular frame to form a quadrangular pyramid frame. The inclined ball guide groove is composed of a pair of diagonal ends in the rectangular frame that are lower than the level of the adjacent diagonal ends, and the lower diagonal ends are provided with a vertical ball guide pipe, and the top of the ball guide pipe is located outside the table , the top surface of the ball guide pipe is flush with the surface of the ball table, the lower end of the ball guide pipe is provided with a goal opening corresponding to the ball guide groove, a ball baffle is provided at the goal entrance, the inner hole of the ball guide pipe and the ejection device Corresponding; the ejection device includes a base plate, a bracket, a pedal and a return spring, the bracket is vertically fixed on the base plate, the middle part of the pedal is connected to the upper end of the bracket through a hinge, one end of the pedal is tilted, and the tilted end of the pedal is connected to the base plate through a return spring. The other end of the pedal extends outwards and is bent with an ejection plate, and the ejection plate is located in the ball guide pipe, wherein the pedal cooperates with the rope through the guide wheel to make the ball blocking plate move up and down along the ball guide pipe axis.

To further define the above technical solution, the ball collecting net is made of nylon material.

As a further improvement to the above technical solution, a rubber layer is laid on the inner surface of the ball guide groove.

Beneficial effects: when the utility model is used, the table tennis balls rolling down around the table pass through the collection device under the table and flow back to the ejection device from the surroundings, and the table tennis balls can be ejected to the table along the pipeline by lightly stepping on the ejection device with your feet , the athlete can directly hold the table tennis ball ejected from the mouth of the pipe with his hand, thereby completing the picking up process of the table tennis ball under the table; while the pedal mechanism ejects the table tennis ball, the ball baffle is pulled up by the reversing rope, and the ball will be queued up to wait. The next table tennis ball is introduced into the ejection position, thereby realizing continuous ejection action, which greatly solves the problem of inconvenient picking up table tennis balls under the table; it has the following advantages: First, the net made of nylon material reduces high-speed impact. The table tennis ball on the surface of the goal net rolls down at a low speed along the inclined net surface into the ball guide groove; secondly, the inclined ball guide groove makes the table tennis balls entering the ball guide groove move to the lower place at a low speed by its own weight, and Automatically gather at the ball guide pipe; third, there is a rubber layer on the inner surface of the ball guide groove, which acts as a buffer for the falling table tennis balls, and avoids hard collision between the table tennis ball and the ball guide groove; fourth, the ejection device One action has the dual functions of introducing and ejecting the table tennis ball, thereby realizing continuous action; fourth, the utility model has simple overall structure, convenient operation and low manufacturing cost.

Detailed ways

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a collection and ejection device under a table tennis table includes a collection device and an ejection device that can be fixed under the table tennis table; the collection device includes a central support frame 1, The top of the center support frame 1 is connected with one end of four support rods 2, and the other ends of the four support rods 2 are connected with the rectangular frame 3 to form a frame similar to a quadrangular pyramid. Jointly tightened and fixed, wherein the rectangular frame 3 is composed of four inclined ball guide grooves, a pair of diagonal ends in the rectangular frame 3 are lower than the level of the adjacent diagonal ends, and the lower diagonal ends are provided with vertical The ball guide pipeline 5, the top of the ball guide pipeline 5 is positioned at the outside of the ball table 6, the top surface of the ball guide pipeline 5 is flush with the ball table 6 faces, and the lower end of the ball guide pipeline 5 is provided with a ball opening corresponding to the ball guide groove. The ball opening is provided with a ball stopper 7, and the inner hole of the ball guide pipe 5 corresponds to the ejection device; the ejection device includes a base plate 8, a support 9, a pedal 10 and a return spring 11, and the support 9 is vertically fixed on the base plate 8, and the pedal 10 The middle part of the pedal 10 is connected to the upper end of the bracket 9 through a hinge, and one end of the pedal 10 is tilted, and the tilted end of the pedal 10 is connected to the bottom plate 8 through a return spring 11, and the other end of the pedal 10 is extended outwardly and bent with an ejection plate 12, and the ejection plate 12 Located in the ball guide pipe 5, wherein the pedal 10 cooperates with the rope 14 through the guide wheel 13 to make the ball baffle move up and down along the axial direction of the ball guide pipe; the ball receiving net 4 is made of nylon material for reducing high-speed impact. The table tennis ball on the surface of the goal net rolls down the ball guide groove at a low speed along the inclined net surface; a rubber layer is laid on the inner surface of the ball guide groove to buffer the falling table tennis balls and avoid The table tennis ball collided head-on with the guide groove.

The working principle of the ejection device: When the table tennis ball enters directly below the ball guide pipe along the ball guide groove, it reaches the end of the ejection plate of the pedal. The inner wall of the pipe is ejected to the surface of the table, and then the ball is held by the player's hand to complete the ejection process of the table tennis ball; while the end of the pedal ejection plate is lifted, the ball baffle is pulled up by the rope and the guide wheel, and the players waiting in line are pulled up. The first ping-pong ball is introduced into the ejection plate to prepare for the next ejection. When the foot power disappears, the return spring lifts the cocked end of the pedal, and the ejection mechanism returns to the initial state, and at the same time the ball baffle descends to the initial position, blocking other table tennis balls from entering the ejection pipeline; The time of the ejection board should be short, that is to say, the reset ejection board waits for the arrival of the next table tennis ball, otherwise, if the ball arrives first, the table tennis ball will arrive under the ejection board and cannot be ejected.
