Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

The utility model provides a pick up ball dolly of tennis in batches, includes the dolly body, sets up box 1 that is used for accomodating the tennis on the dolly body and the ball device of picking up that is used for picking up the tennis, wherein:

the ball picking device comprises a sleeve 2 and a pressing rod 3, the pressing rod 3 is fixedly connected with the sleeve 2 through two connecting rods 4 fixed on two sides of the upper end of the sleeve 2, the inner diameter of the sleeve 2 is larger than the diameter of a tennis ball, openings are formed in the bottom and the top of the sleeve 2 respectively to form a ball inlet 5 and a ball outlet 6, and a ball inlet mechanism enabling the tennis ball to enter in a single direction is mounted on the ball inlet 5;

the goal mechanism is as shown in fig. 2 and fig. 3, and comprises a wide barrel 18 detachably connected to the goal 5, two blocking pieces 19 respectively connected to two sides inside the wide barrel 18 through two connecting shafts 24, and two limiting baffles 20 fixed to edges of two other sides inside the wide barrel 18, wherein a spring 21 connected to the edge of the wide barrel 18 is arranged at the edge of each blocking piece 19.

The wide cylinder 18 has a larger diameter than the sleeve 2, and is shaped like a trumpet (not limited to a circle, but also can be a square), so that tennis balls to be picked can be aligned more conveniently. The two baffles 19 are kept horizontal due to the presence of the limit baffle 20 when no external force is applied. When picking up the tennis, the hand-held pressing rod 3 presses downwards, the tennis applies upward reaction force to the two blocking pieces 19 to enable the blocking pieces 19 to be turned upwards, a gap is formed in the middle of the two blocking pieces 19 after the two blocking pieces 19 are turned upwards to enable the tennis to pass through, and when the tennis completely passes through, the two blocking pieces 19 are located at the lower ends of the tennis. Due to the traction force of the spring 21 on the blocking piece 19, the blocking piece 19 is pressed downwards and limited by the limiting baffle 20, and tennis balls are prevented from falling.

An inlet 8 is arranged on a top plate 7 of the box body 1, a ball outlet 6 on the ball picking device is communicated with the inlet 8 through a ball loading channel 9, and an end plate 10 of the box body 1 can be opened to take out tennis balls contained in the box body 1. As the number of tennis balls in the sleeve is increased, the tennis balls are vertically arranged, and when reaching a certain number, the tennis balls are extruded from the ball outlet 6 and enter the box body 1 through the ball loading channel 9 and the inlet 8. After the ball is picked up, the sleeve 2 is reversely erected so that all the tennis balls in the sleeve can enter the box body 1 to be stored. For the next use, the end plate 10 is opened and removed.

Example 2

This embodiment is described based on embodiment 1, and its preferred structure is described.

Preferably, the trolley body comprises an armrest 11, a vehicle plate 12 and four wheels 13 arranged at the bottom of the vehicle plate 12, and the end plate 10 of the box body 1 is hinged with the edge of the vehicle plate 12 and is locked or unlocked with the box body 1 through a locking assembly.

The end plate 10 is hinged with the vehicle plate 12, when the tennis ball needs to be taken out, the locking assembly is opened, the side plate hinged on the edge of the vehicle plate is turned downwards, and the tennis ball in the box body 1 is taken out.

Preferably, the locking assembly is as shown in fig. 4, and includes a connecting piece 14 fixed on the end plate 10 and a protruding ring 15 fixed on a corresponding position of the box body 1, a through hole 16 for the protruding ring 15 to pass through is formed in the connecting piece 14, and the end plate 10 and the box body 1 are locked by a bolt 17 after the protruding ring 15 passes through the through hole 16.

Preferably, a raised pad is disposed at the bottom of one end of the box body 1 far away from the end plate 10 to enable the box body 1 to be inclined. The box body 1 is obliquely arranged, so that tennis balls in the box body 1 can automatically roll out after the end plate 10 is opened, and the tennis balls can be taken out conveniently.

Preferably, the ball loading channel 9 is a corrugated hose, which has the advantages of convenient bending, adjustable length and convenient use.

Preferably, the width of the cart plate 12 is greater than the width of the box 1, a ball-picking device placing platform is arranged on the cart plate 12, and a baffle 22 is fixed on the outer edge of the ball-picking device placing platform. When the ball picking trolley is not suitable for use, the ball picking device can be placed on the ball picking device placing platform and is prevented from rolling down through the baffle plate 22, and the ball picking trolley is convenient to store.

Preferably, short bristles (not shown) are provided inside the sleeve 2, so that collected tennis balls can be easily brushed to remove attached dust, and friction between the tennis balls and the inner wall of the sleeve 2 can be increased to prevent the tennis balls from falling out.

Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used in the embodiments for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Moreover, relational terms such as "first" and "second," and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
