Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be seen from fig. 1 to 3, the present invention comprises two first connecting rods 1 arranged horizontally in a front-back direction and side-by-side manner at intervals, the end portions of the two first connecting rods 1 are hinged to form a rectangular frame structure through two sets of connecting members, each connecting member comprises a horizontal support rod 2 in a left-right direction, the two end portions of each support rod 2 are respectively hinged to a second connecting rod 3 capable of rotating in a horizontal plane, the second connecting rods 3 are freely hinged to the corresponding end portions of the first connecting rods 1, an electric push rod 4 with an axis vertical to the support rod 2 is arranged above each support rod 2, the fixed ends of the two electric push rods 4 are fixedly connected with each other, the extending ends are respectively connected with the corresponding support rods 2 through vertical rods 5, each first connecting rod 1 is provided with at least one L-shaped guide rod 6, the end 5 of the L-shaped guide rod 6 is fixed to the first connecting rod, the cross rod part of the L-shaped guide rod 6 is sleeved with a pressure spring 7 which can enable the L-shaped guide rod 6 to reset towards the direction far away from the electric push rod 4, the parts of the two second connecting rods 3 in one group of connecting pieces, which are close to the supporting rod 2, are provided with arc-shaped parts 8 protruding outwards, and the two arc-shaped parts 8 can form a circular hole in the front and back direction of the rotating axis of the second connecting rods 3.

In order to realize better tennis gathering of the first connecting rod 1 and the second connecting rod 3, a guard plate 9 with the upper end inclined outwards is fixed on the first connecting rod 1 and the second connecting rod 3 along the length direction of the first connecting rod and the second connecting rod, and the end of the vertical rod 5 of the L-shaped guide rod 6 is fixed on the guard plate 9 on the first connecting rod 1.

In order to facilitate the movement of the device when collecting tennis balls, two rollers 10 having main lines parallel to the first links 1 are fixed on the outer side of each first link 1, and the lower outer edge surface of each roller 10 is higher than the lower outer edge surface of each first link 1.

In order to realize the installation of the pressure spring 7, a U-shaped frame 11 is fixed below the electric push rod 4, the opening of the U-shaped frame 11 faces the end part of a transverse rod corresponding to the L-shaped guide rod 6, the end part of the transverse rod of the L-shaped guide rod penetrates through and is slidably installed at the bottom of the U-shaped frame 11, one end of the pressure spring 7 is fixed on the L-shaped guide rod 6, and the other end of the pressure spring 7 is fixed at the bottom of the U-shaped frame 11.

In order to facilitate the holding of the device, the two electric push rods 4 are stacked up and down, the rubber anti-slip sleeves 12 are sleeved on the fixed positions at the two ends, and the switches of the electric push rods 4 are arranged on one sides of the rubber anti-slip sleeves 12.

The specific working process of the invention is as follows: the initial state of the device is that the electric push rod 4 is in a contracted state, the first connecting rods 1 on the left side and the right side move reversely under the resetting action of the pressure spring 7, the two first connecting rods 1 are always kept parallel and perpendicular to the L-shaped guide rod 6 under the guiding action of the L-shaped guide rod 6, when the two first connecting rods 1 are far away from each other, the second connecting rod 3 is pulled and is made to be perpendicular to the first connecting rods 1, the second connecting rods 3 and the support rod 2 form a square rectangular frame structure under the state, the device is held by hand and placed on the ground from the top, and tennis balls in the rectangular frame are covered.

At the moment, the electric push rods 4 are opened, so that the extending ends of the two electric push rods 4 extend out at the same speed synchronously, the support rod 2 is driven and moves reversely in the process, the second connecting rod 3 rotates to the front and back directions of the horizontal axis gradually from the original horizontal left and right directions of the axis, the first connecting rod 1 is pulled by the second connecting rod 3 and moves the two first connecting rods 1 in the same direction in the process, the axial direction of the first connecting rod 1 is kept unchanged under the action of the L-shaped guide rod 6 in the process, the pressure spring 7 is compressed when the two first connecting rods 1 approach each other, when the second connecting rod 3 rotates to the front and back directions of the horizontal axis when the two first connecting rods 1 approach each other, the square rectangular frame is stretched to the rectangular frame, tennis balls originally dispersed in the square rectangular frame are integrally extruded and arranged into a straight line, the tennis ball lifting device is lifted, the first connecting rods 1 on both sides and the long connecting rods 3 rotating to the front and back directions of the horizontal axis are lifted, and the tennis ball can be separated from the round-like structure formed by the arc-shaped part 8 to the collecting frame by inclining the device.

After the tennis collection is finished, the electric push rod 4 is driven to contract reversely, and the original long rectangular frame is converted into a square rectangular frame again under the combined action of the resetting action of the pressure spring 7, the guiding action of the L-shaped guide rod 6 and the contraction action of the electric push rod 4, and the tennis can be collected again.

Compared with the traditional equipment, the device has the following advantages:

1. the device realizes the transformation of a square rectangular frame and a long strip-shaped rectangular frame together with the hinging of the first connecting rod 1 and the connecting piece, the square rectangular frame has large area and can better cover tennis balls in the area, the rectangular frame realizing the direction through the driving device is changed into the long strip-shaped rectangular frame, the area is reduced, and meanwhile, the distance between two long edges of the long strip-shaped rectangular frame is smaller than the diameter of the tennis balls, so that the tennis balls can be randomly arranged and transformed into straight line arrangement in the transformation process, the tennis balls can be conveniently lifted, the diameter of a round-like structure formed when the two arc-shaped parts 8 correspond to each other is larger than the tennis balls, and the following tennis balls can be conveniently separated and collected from the round-like structure.

2. This device prevents through backplate 9 that the connecting rod from removing the condition emergence that causes the tennis cross the connecting rod that the connecting rod moved too fast when collecting the tennis, and the gyro wheel 10 of fixing realizes on first connecting rod 1 simultaneously that first connecting rod 1 and ground height remain unanimous throughout, makes things convenient for the syntropy of first connecting rod 1 to remove simultaneously.
