The utility model discloses a kind of novel running broad jump demonstration teaching aid, it belongs to physical culture action demonstration equipment technical field, it comprises demonstration board (1), movement locus groove (2), folding image (3), slip fixture (4), magnetite (5) is fixed in action, action limits magnetite (6), the centre of described demonstration board (1) is provided with a movement locus groove (2), the middle card of movement locus groove (2) is connected to slip fixture (4), the outside of slip fixture (4) is fixed with folding image (3), the four limbs of described folding image (3) are provided with action and fix magnetite (5), the back side of described demonstration board (1) is provided with several action and limits magnetite (6).Its design is ingenious, adopts the method for image simulation demo, decomposes the action point in long-jump course of action and lime light, avoids the injury caused of action only specification.
Description
Technical field
The utility model relates to a kind of novel running broad jump demonstration teaching aid, belongs to physical culture action demonstration equipment technical field.
Background technology
Track and field sports jump event.Also known as running broad jump.By run-up, take-off, soaring and the action such as landing forms.Sportsman is run-up linearly, uses monopodia take-off after take-off board frontal line, through flight phase, then lands in sand pit with biped.
Take off leg will to experience on pedal and put pin, cushion, pedal and stretch 3 stages.While taking off leg and pushing off ground, swing arm and lead leg and want cooperation to do wobbling action, its main points come back, square one's shoulders, carry shoulder, pull out waist.Bearing of body in the air is generally divided into knee-tuck type, hang style, run-in-the-air 3 kinds.No matter adopt which kind of bearing of body in the air, both legs have " stride in air " action of a stride position in the moment that take-off is liftoff.Knee-tuck type requires before landing, and both legs is carried to front and is held high as far as possible and land.
Hang style requirement is transferred after soaring and is led leg and both arms, and hip, chest are fully launched, then abdomen-curl leg-raising lands.Run-in-the-air adopts 2 step half-sum 3 steps half, two kinds of technology when soaring.Require aloft do significantly before and after take a step to change leg action, and with two-arm cooperation.Landing generally has " front fall buffer method ", " side fall buffer method ", " sitting stern buffer method ".Its objective is and maintain good body gravity balance, avoid injury accident occurs.
Running broad jump motion to action norm require higher, if action lack of standardization be easy to injured, in daily teaching process of physical education, do not have image action instruction, entirely with oral account explanation, vivid not.
Utility model content
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of novel running broad jump demonstration teaching aid, and its design is ingenious, adopts the method for image simulation demo, decompose the action point in long-jump course of action and lime light, avoid the injury caused of action only specification.
A kind of novel running broad jump demonstration teaching aid of the present utility model, it comprises demonstration board, movement locus groove, folding image, slip fixture, magnetite is fixed in action, action limits magnetite, the centre of described demonstration board is provided with a movement locus groove, the middle card of movement locus groove is connected to slip fixture, the outside of slip fixture is fixed with folding image, the four limbs of described folding image are provided with action and fix magnetite, and the back side of described demonstration board is provided with several action and limits magnetite.
As preferably, described folding image adopts emulational leather to make.
As preferably, the magnetic pole that magnetite is fixed in described action is contrary with the magnetic pole that action limits magnetite.
During the utility model operation, by regulating the slip fixture position in the middle of image, along with the movement of image position, the sucking action that image four limbs are subject to back side magnetite coordinates manually adjustment, reaches the effect of demostrating action.
The beneficial effects of the utility model: its design is ingenious, adopts the method for image simulation demo, decomposes the action point in long-jump course of action and lime light, avoid the injury caused of action only specification.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structure schematic diagram of the present utility model.
In figure: magnetite-5, action restriction magnetite-6 are fixed in demonstration board-1, movement locus groove-2, folding image-3, slip fixture-4, action.
Embodiment
As shown in Figure 1 to Figure 2, this embodiment is by the following technical solutions: it comprises demonstration board 1, movement locus groove 2, folding image 3, slip fixture 4, magnetite 5 is fixed in action, action limits magnetite 6, the centre of described demonstration board 1 is provided with a movement locus groove 2, the middle card of movement locus groove 2 is connected to slip fixture 4, the outside of slip fixture 4 is fixed with folding image 3, the four limbs of described folding image 3 are provided with action and fix magnetite 5, and the back side of described demonstration board 1 is provided with several action and limits magnetite 6.
Wherein, described folding image 3 adopts emulational leather to make.The magnetic pole that magnetite 5 is fixed in described action is contrary with the magnetic pole that action limits magnetite 6.
During the operation of this embodiment, by regulating the slip fixture position in the middle of image, along with the movement of image position, the sucking action that image four limbs are subject to back side magnetite coordinates manually adjustment, reaches the effect of demostrating action.
The design of this embodiment is ingenious, adopts the method for image simulation demo, decomposes the action point in long-jump course of action and lime light, avoids the injury caused of action only specification.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
