Abstract
The invention relates to a ping pong ball flying drop point control device which comprises lifting rods, fixing clamps, a frame and a plurality of sliders. The size of the frame is matched with that of one side of a ping pong table. The frame comprises frame rods. The parallel frame rods on two sides are connected with the frame rod on one side through right-angle connecting tubes and connected with frame rod on the other side through two crisscross fixing clamps. The lifting rods are respectively mounted on the fixing clamps on two sides. The upper end of each lifting rod is connected with a height line. Each lifting rod penetrates the vertical tube of the corresponding crisscross fixing clamp. A spiral fastening handle is disposed on each fixing clamp which is loosened and fixed through the spiral fastening handle. The sliders are disposed on the frame rods. A transverse dividing line and a longitudinal dividing line are disposed between two corresponding sliders and move on the frame rods through the sliders. By using the height difference of the existing ping pong nets and lifting rod lines, the flying trajectory of a ping pong ball is controlled in a space of the height difference, and ping pong ball can fly in the specific space.
Description
Technical field
The invention belongs to sports training device field, relate in particular to a kind of table tennis flight drop point control device.
Background technology
Too high and drop point is at random for table tennis beginner table tennis ball flying path when the push and block technology of study table tennis basic fundamental, the reason causing is due to held table tennis bat bat tilted backward and muscular tone.By requiring the table tennis that table tennis beginner push and block go out to pass through at the area of space of restriction, only have table tennis beginner's arm initiatively to protract and table tennis leans forward, just can reach the action request that masters a skill, and then correct the object of table tennis push and block technical movements.The object of table tennis is exactly the variation by drop point, transfers the other side, causes error, so that one's own side's victory by points.By setting different big or small drop points region, cultivate table tennis fan and control drop point consciousness, improve table tennis fan's muscle control ability and technical and tactical levels.Change by effective table tennis drop point, and then improve ping-pong contest scoring rate.
Existing Table tennis skill teaching is teacher modeling and student's Imitation Exercise and without the auxiliary teaching process of any specialized equipment.Only under professor person's concrete guide, learner could further improve technical movements, owing to being subject to learner's the impact of body harmony, psychological quality and comprehension ability, often improve that the efficiency of technical movements is lower and effect is poor, affect self-directed learning process, feel that exercise process is uninteresting, notice and learning interest decline.
Summary of the invention
Technical problem to be solved by this invention is to provide effectively aided education of one, controls the table tennis flight drop point control device of drop point.
The present invention realizes like this, this device comprises elevating lever, geometrical clamp, frame and multiple slide block, wherein frame size matches with table tennis table one side size, frame is made up of side jamb rod, two side jamb rods that parallel are connected by right angle tube connector with the side jamb rod of a side, be connected by two cross geometrical clamps with opposite side side jamb rod, two elevating levers are arranged on respectively on the geometrical clamp of both sides, elevating lever upper end connects altitude line, described elevating lever penetrates in the vertical duct of cross geometrical clamp, screw-tightened handle is set on geometrical clamp, unclamp with fixing by screw-tightened handle, the vertical plane space that height of formation does not wait, slide block is set on side jamb rod, between corresponding two slide blocks, be provided with horizontal dividing line and longitudinal dividing line, movement by slide block on side jamb rod, laterally dividing line intersects to form with longitudinal dividing line the region that differs in size.Slide block is T-shaped;
Further, elevating lever bilateral symmetry arranges frame and right angle tube connector.
Compared with prior art, beneficial effect is in the present invention:
The difference in height of utilizing existing ping-pong racket net height and elevating lever line, is controlled at table tennis ball flying path in difference in height space.For guaranteeing that table tennis flight is in specific space, the technical movements completing technology action request that table tennis practitioner is only protracted with forearm and table tennis leans forward.Along with reducing of difference in height space, can improve and impact table tennis speed, and guarantee that table tennis drops in table tennis table.
Utilize mobile slide bar to move and drive rubber band to intersect, form the plane domain varying in size, require table tennis practitioner that table tennis is hit down in appointed area, accomplish " which refers to, which is beaten ".By control band size, region distance, can adjust exercise difficulty, reaches multi-functional.
The present invention's (plug and unplug, press from both sides and can realize) easy to install; Practical, function is many (correcting technology action, control drop point, exercise difficulty is adjustable); Interesting strong (passing through, experience successfully joyful); Safe, cost low (can adopt plastics, rubber band or cord to realize)
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the embodiment of the present invention provides.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, this device comprises elevating lever 2, geometrical clamp 6, frame 3 and multiple slide block 4, wherein frame 3 sizes match with table tennis table cut-off rule one side size, frame 3 is made up of side jamb rod, two side jamb rods that parallel are connected by right angle tube connector 5 with the side jamb rod of a side, be connected by two cross geometrical clamps 6 with opposite side side jamb rod, two elevating levers 2 are arranged on respectively on both sides geometrical clamp 6, elevating lever 2 upper ends connect altitude line 1, elevating lever 2 penetrates in the vertical duct of cross geometrical clamp 6, screw-tightened handle is set on geometrical clamp 6, unclamp with fixing by screw-tightened handle, the vertical plane space that height of formation does not wait, slide block 4 is set on side jamb rod, slide block 4 is T-shaped, between corresponding two slide blocks, be provided with horizontal dividing line and longitudinal dividing line, movement by slide block on side jamb rod, laterally dividing line intersects to form with longitudinal dividing line the region that differs in size.
This device installation method:
First slide block 4 is inserted in to side jamb rod, side jamb rod inserts right angle tube connector 5 and forms frame.Again elevating lever is inserted to elevating lever geometrical clamp.Elevating lever top is connected, utilizes rubber band tension-stretched with rubber band; Rubber band is connected with slide block 4, utilizes rubber band tension-stretched.Move by elevating lever oscilaltion and slide block 4, form differing heights space and the region that differs in size.
The device assembling is directly enclosed within on table top 7.
Embodiment 2
Be with the difference of embodiment 1, elevating lever bilateral symmetry arranges frame and right angle tube connector.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
