Abstract
The utility model relates to a middle school sports teaching is with device of hurdling contains the base, there is corresponding hurdle the both sides of base rigid coupling respectively, hurdle's inboard articulates respectively has corresponding locating lever, the rigid coupling has a railing between two locating levers, hurdle's inboard all is equipped with corresponding locating hole, there is corresponding position sleeve through location spring assembly in the locating hole, it is globular that the semicircle is set to the outer end of position sleeve, the locating lever with be equipped with the orbed holding tank of corresponding semicircle on the corresponding position of position sleeve, the locating lever is positioned on the corresponding hurdle through the cooperation of the position sleeve on its holding tank and the hurdle, the surface of railing covers and is equipped with the corresponding rubber buffer layer of one deck. The utility model discloses the condition about being stumbleeed appears in produced pain in the time of can effectively alleviateing the collision railing when preventing to hurdle the motion.
Description
Technical field
The utility model belongs to physical education equipment, specifically refers to a kind of device of hurdling for teaching of physical education in high school.
Background technology
Hurdle campaign is the speed that can improve practitioner, strength, coordination, every health such as pliable and toughThe sports events of quality, in the physical education course of various kinds of schools, hurdle campaign be one very general,And be subject to that student welcomes sports events. But student is not professional sportsman after all, its carry out acrossWhen hurdle moves, easily there is collision railing, or even knock the situation of railing down. Easily cause sporter to produceVery painful pain, or even there is tripping the injured situation that causes. Therefore, hurdle campaign in the time having physical education,Particularly Middle School PE Classes class hour, though welcome, seldom really realize the training of hurdling. Middle school student are hinderedFor the cognitive and experience of the project of hurdling. Therefore, designing a collision railing time institute that can effectively alleviate producesRaw pain, occurs while preventing hurdle campaign that the physical education device of hurdling being tripped is the utility modelResearch purpose.
Summary of the invention
The utility model provides a kind of device of hurdling for teaching of physical education in high school, and it can effectively alleviate collision hurdle, while preventing hurdle campaign, there is situation about being tripped in the pain producing when bar.
The technical solution of the utility model is as follows: a kind of device of hurdling for teaching of physical education in high school, comprise base,The both sides of described base are connected with respectively corresponding hurdle frame, and the inner side of described hurdle frame is hinged with respectively accordinglyBackstay, is connected with a railing between described two backstays, and the inner side of described hurdle frame is equipped with accordinglyLocating hole, has corresponding positioning sleeve by retainer spring device in described locating hole, outside described positioning sleeveIt is spherical that end is arranged to semicircle, and described backstay is provided with accordingly on the position corresponding with described positioning sleeveThe holding tank that semicircle is spherical, described backstay is coordinated and is positioned with the positioning sleeve on hurdle frame by its holding tankOn corresponding hurdle frame; The outer surface of described railing covers and is provided with the corresponding cushion rubber layer of one deck.
Described positioning sleeve is to be prepared from by elastomeric material.
Advantage of the present utility model: frame inner side in hurdle of the present utility model is equipped with corresponding locating hole, locationIn hole, have corresponding positioning sleeve by retainer spring device, it is spherical that semicircle is arranged in the outer end of positioning sleeve, fixedPosition bar is provided with the spherical holding tank of corresponding semicircle on the position corresponding with positioning sleeve, and backstay passes throughIts holding tank coordinates and is positioned on corresponding hurdle frame with the positioning sleeve on hurdle frame. Once student touches railing,If when power reaches certain degree, positioning sleeve is squeezed out corresponding holding tank, backstay is around itRotate with the pin joint of hurdle frame, prevent that student from falling down, sense eases the pain simultaneously. Due to positioning sleeveIt is spherical that semicircle is arranged in outer end, and its turnover holding tank can not produce any stuck situation, effectively guarantees thisThe security and stability of utility model. If power when student touches railing is less, positioning sleeve can be not squeezedExtrude corresponding holding tank, because touching power is little, therefore, in the effect of cushion rubber layer, collide railingTime the pain that produces just not too large. For safety and protection student's object, the utility model is suitableBe combined in teaching of physical education in high school and promoted.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
Fig. 3 is the structural representation of the utility model positioning sleeve.
Detailed description of the invention
Show embodiment by reference to the accompanying drawings to knot of the present utility model for the ease of it will be appreciated by those skilled in the art thatStructure is described in further detail:
With reference to figure 1-3, a kind of device of hurdling for teaching of physical education in high school, comprises base 1, described base 1Both sides be connected with respectively corresponding hurdle frame 2, the inner side of described hurdle frame 2 is hinged with respectively corresponding locationBar 3, is connected with a railing 4 between described two backstays 3, and the inner side of described hurdle frame 2 is equipped with correspondingLocating hole, have corresponding positioning sleeve 6, described location by retainer spring 5 devices in described locating holeIt is spherical that semicircle is arranged in the outer end of cover 6, and described backstay 3 is in the position corresponding with described positioning sleeve 6Be provided with the spherical holding tank of corresponding semicircle, described backstay 3 passes through on its holding tank and hurdle frame 2Positioning sleeve 6 cooperations are positioned on corresponding hurdle frame 2; The outer surface of described railing 4 covers and is provided with one deck phaseThe cushion rubber layer 7 of answering. Described positioning sleeve 6 is to be prepared from by elastomeric material.
Once student touches railing 4, if when power reaches certain degree, positioning sleeve 6 is extrudedGo out corresponding holding tank, backstay 3 rotates around the pin joint of itself and hurdle frame 2, prevents that student from fallingFall, sense eases the pain simultaneously. Due to the outer end of positioning sleeve 6, to be arranged to semicircle spherical, and it passes in and out holding tankCan not produce any stuck situation, effectively guarantee security and stability of the present utility model. If student touchesHour, positioning sleeve 6 can not be squeezed out corresponding holding tank to the power of touching railing 4, due to touching powerRoad is little, and therefore, in the effect of cushion rubber layer 7, the pain producing when collision railing is just not too large.
The foregoing is only preferred embodiment of the present utility model, all according to the utility model claimThe equalization of doing changes and modifies, and all should belong to covering scope of the present utility model.
