Abstract
The invention belongs to the field of sports equipment and relates to a tennis racket capable of changing mass distribution by filling mercury into a head framework pipeline. The tennis racket is functionally characterized in that the mass distribution of the tennis racket can be changed in a racket swinging process. The structure is characterized by comprising a head framework composed of a hollow metal pipeline, a triangular part composed of a hollow metal pipeline, a hollow-pipe-shaped handle section, a plug and the mercury in the pipelines, wherein the cross section of an edge frame of the head frame is 8-shaped; small holes are formed in upper and lower o-shaped connection parts of the 8-shaped hollow pipeline at a certain distance and are used for threading a net wire. The hollow metal pipeline for forming the head frame, the hollow metal pipeline for forming the triangular part and the hollow pipeline for forming the handle section are communicated with one another; the hollow pipelines are internally filled with a certain amount of the mercury; the mercury filling amounts are different so that the weight of the tennis racket is changed. The tennis racket further comprises a special bottle for filling the mercury and a special bottle for filling sulfur powder; and when the mercury in the tennis racket is increased and reduced and the mercury is carelessly leaked out, the sulfur powder is sprayed and toxic mercury steam is not generated.

Detailed description of the invention
Embodiment 1: by the tennis racket of water-filling silver in Fig. 1 processing head frame pipeline.When using this tennis racket, as hope at the incipient stage barycenter of swinging the bat near handle section, at square stance barycenter near head frame, then swing the bat start time by the head frame of tennis racket upwards, mercury is all in the pipeline of handle section, and when starting to swing the bat, the barycenter of tennis racket is near handle section, after swinging the bat, due to the effect of centrifugal force, mercury can flow to a frame, thus makes the barycenter of tennis racket near head frame.This just functionally reaches the requirement changing Mass Distribution in the process of swinging the bat.
Embodiment 2: substantially the same manner as Example 1, difference sets up to cut off a point in a frame pipeline, and so-called partition point is exactly an embolus in pipeline, and available metal material is closed.The conduit ring-shaped of example 1 frame communicates, and does not cut off a little, and mercury is in swinging the bat at a high speed, and due to the effect of centrifugal force, mercury will flow to the distalmost end of head frame.
Set up in the pipeline of head frame after cutting off point, mercury can only flow to the position cutting off point farthest.
When only establishing one to cut off point, there are two kinds of situations
A kind of situation is one and cuts off point and to be located at a frame pipeline in apart from handle section farthest, cuts off that evenly to be divided equally by the pipeline of head frame be two sections, and when swinging the bat, mercury still can flow to the distalmost end of a frame, and functionally difference is little with the example 1 do not cut off a little.
Another kind of situation is one, and to cut off that point is located in a frame pipeline be not apart from handle section farthest, cut off point and the pipeline of head frame is divided into two sections unevenly, there is one section longer, there is one section shorter, due to the effect of centrifugal force when swinging the bat at a high speed, the mercury flowed in the longer segment pipe of pipeline of head frame can arrive the distalmost end of a frame, and the mercury flowed in the shorter segment pipe of pipeline of head frame can only arrive and cut off some place.Such Mass Distribution makes barycenter not on the bisector of head frame, namely not on the extended line of handle section straight line.
Embodiment 3: substantially the same manner as Example 1, difference sets up two to cut off point in a frame pipeline, two are cut off point and the pipeline of head frame are divided into three sections, middle one silver of cutting off the water supply cannot arrive, mercury only arrives two and cuts off some place, changes the position cutting off point and also just changes the changeable scope of Mass Distribution.
Embodiment 4: substantially the same manner as Example 1, difference has 4 positions cutting off point in a frame pipeline and in the pipeline of triangle portion, according to different Mass Distribution requirements, set 4 and cut off point, aperture and sealing plug with matching that hollow pipe between every two partition points has one to communicate with the external world, at this moment all can fill a certain amount of mercury (also can not fill mercury) in the pipeline between every two partition points, mercury cuts off flowing between point at two.
Embodiment 5: substantially the same manner as Example 1, difference is the flow media of filling is water.Although the proportion of water is only 1g/ml, more much smaller than the proportion 9.8g/ml of mercury, water is drawn materials conveniently.
Above-described embodiment is only in order to illustrate the present invention.The various distortion that the person that is familiar with technique makes in the scope of the present invention's spirit, modification and application all should belong in category of the present invention.
