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 the support rod 2 are respectively hinged to a second connecting rod 3 capable of rotating in a horizontal plane, the free end of the second connecting rod 3 is respectively hinged to the corresponding end portion of the first connecting rod 1, the outer side of each support rod 2 is provided with a horizontally placed T-shaped rod 4, the vertical rod end of the T-shaped rod 4 is vertically and fixedly connected to the support rod 2, the two end portions of the horizontal rod of the T-shaped rod 4 are respectively fixed with a tension spring 5, the other end of the tension spring 5 is fixed to the corresponding second connecting rod 3, an electric push rod 6 with an axis vertical to the support rod 2 is arranged above each support rod 2, and the fixed ends of the two electric push rods 6 are mutually fixedly connected, the extending ends are respectively connected with the corresponding support rods 2 through vertical rods 7, the parts, close to the support rods 2, of the two second connecting rods 3 in one group of connecting pieces are provided with arc-shaped parts 8 protruding outwards, and the two arc-shaped parts 8 can form a circular hole when the second connecting rods 3 rotate to the front and back directions of the axis.
In order to realize better tennis ball 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.
In order to facilitate the movement of the device when collecting tennis balls, two rollers 10 with axes parallel to the first links 1 are respectively 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 that the second connecting rod 3 can keep the horizontal left-right direction of the axis when being reset by the tension spring 5, the outer sides of the left end and the right end of each supporting rod 2 are respectively provided with a limiting block 11, and when the second connecting rod 3 is reset to the horizontal left-right direction of the axis, the limiting blocks 11 limit the second connecting rod 3.
In order to facilitate the holding of the device, the two electric push rods 6 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 6 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 this device is that electric putter 6 is the shrink form, realize that two second connecting rods 3 on the same group of connecting piece are in coaxial state and the axis keeps the level left and right sides orientation under the limiting displacement of extension spring 5 and limiting displacement of stopper 11 this moment, two first connecting rods 1 keep away from each other this moment, second connecting rod 3 is dragged to be the vertical state with first connecting rod 1, first connecting rod 1 under this state, second connecting rod 3 constitutes a square rectangular frame structure with bracing piece 2, handheld this device and place it subaerial from the top this moment, the tennis in the rectangular frame is covered.
At the moment, the electric push rods 6 are opened, so that the extending ends of the two electric push rods 6 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 from the original horizontal left-right direction of the axis to the horizontal front-back direction of the axis gradually, the first connecting rod 1 is pulled by the second connecting rod 3 and enables the two first connecting rods 1 to move oppositely in the process, meanwhile, the second connecting rod 3 rotates from the horizontal left-right direction of the axis to the horizontal front-back direction of the axis gradually, the tension spring 5 is stretched in the process, when the two first connecting rods 1 approach, the second connecting rod 3 rotates to the horizontal front-back direction of the axis, the square rectangular frame is stretched to the long rectangular frame, the tennis balls originally dispersed in the square rectangular frame are extruded and arranged into a straight line integrally, the device is lifted upwards, the first connecting rods 1 at two sides and the second connecting rods 3 rotating to the horizontal front-back direction of the axis lift the tennis balls, 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 ball collecting device is completed, the electric push rod 6 is driven to contract reversely, the second connecting rod 3 rotates to the axis horizontal left-right direction again under the action of the reset pulling of the tension spring 5 and the limiting action of the limiting block 11, and therefore the long-strip-shaped rectangular frame is converted into the square rectangular frame again, and tennis balls 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 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 square rectangular frame is changed into the long strip rectangular frame through the driving device, the area is reduced, and meanwhile, the distance between two long edges of the long strip rectangular frame is smaller than the diameter of the tennis balls, so that the tennis balls can be randomly arranged and linearly arranged 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 realizes preventing through backplate 9 that the connecting rod from removing the condition emergence that the tennis caused crossed the connecting rod at the excessive speed when collecting the tennis, and the gyro wheel 10 of fixing realizes on first connecting rod 1 that first connecting rod 1 and ground height remain unanimous throughout simultaneously, makes things convenient for the removal in opposite directions of first connecting rod 1 simultaneously.
The tennis ball picking device is novel in concept, ingenious in structure and high in practicability, and effectively solves the problems that the existing tennis ball picking device is complex in operation, large in size and low in ball picking efficiency.
