Abstract
The invention relates to a universal double-ended inflatable exercise javelin for soft and hard venues. The structure is mainly as follows: a javelin shaft is of a rubber tube, the diameter at two ends of the rubber tube is smaller than the diameter of a body, a support tube is arranged in the part at the center of gravity of the javelin at the middle part of the javelin shaft, a rubber front seal head and a rubber rear seal head are respectively arranged at the two ends of the javelin shaft, a valve port in which an air needle can be inserted is arranged in the rear seal head, a slotted hole with a cylindrical opening part and a conical inner liner is arranged in the front seal head, the slotted hole corresponding to a javelin head, the middle part of the metal javelin head is of a cylinder, a cone which is connected with the metal javelin head into a whole is arranged at one end of the metal javelin head, the slotted hole is arranged in the other end of the cylinder of the javelin head, liquid pigment can be arranged in the slotted hole, and a soft javelin head which is used for plugging the slotted hole and made of water-absorbing material is arranged at the top end of the slotted hole. According to the universal double-ended inflatable exercise javelin disclosed by the invention, convenient and fast exchange of the soft and the hard javelin heads can be realized on one javelin, the exercise requirements in the hard and the soft venues can be met, a javelin body can not be damaged, the venues can not be damaged, and the javelin is further convenient to carry and store.
Description
Technical field
The present invention relates to a kind of athletic sports appliance, particularly practise the javelin of use.
Background technology
The javelin of existing use is the same with the javelin that match is used, and at stock shape javelin bar front end, is fixed with conical head of javelin, and this head of javelin is a kind of is metal material, and another kind is quality of rubber materials.They have the following disadvantages: 1, metal javelin head only limits to use in soft place; Although rubber head of javelin can be used in soft or hard place, Dan Qiang Jianzha County can not leave a trace on soft or hard ground, cannot measure achievement; 2, the wooden javelin bar of head of javelin connection metal or bamboo uses and easily causes place or javelin bar to damage at hard court; 3, the wooden javelin bar of metal or bamboo goes out to practise not Portable belt.
Summary of the invention
All normally use, javelin or place can not be damaged and the general double end inflatable exercise javelin in portable soft or hard place again to the object of this invention is to provide a kind of soft or hard place.
The present invention mainly includes javelin bar, support column, back-up ring, front and back end socket and head of javelin.Wherein, javelin bar is the rubber tube identical with standard javelin bar external diameter, and its two ends diameter is less than body diameter, is truncated cone shape.In the javelin center of gravity place at this javelin bar middle part, establishing the pipe by rigid material made corresponding with it is support column, and itself and javelin bar inwall are bonding.Best, these support column two ends are made as the annular retaining ring of its auxiliary positioning, and its outer ring surface and javelin bar inner surface are bonding.At above-mentioned javelin bar two ends, be respectively equipped with corresponding with them and by end socket before and after the rubber of its closed at both ends, they and javelin bar are bonding, wherein in rear head, establish half open-work that can insert air tube, it is valve port, in front head, establishing opening portion and be cylindrical is conical slotted eye inside, and this slotted eye is corresponding with head of javelin.This metal javelin centriciput is cylinder, and the cone of its one end for being connected as a single entity with it, establishes slotted eye in this head of javelin cylinder other end, can be provided with liquid pigment, as magic ink in it.On this groove hole end top, be provided with the lid of being made by absorbent material of its shutoff, i.e. soft rifle head.Be preferably in soft rifle head outside and be provided with the outer cover that soft rifle crown portion can be exposed and assist lid location, this outer cover is circular groove shape, and the end is provided with through hole, and perisporium is threaded with head of javelin.
Above-mentioned javelin can be made the rifle body that meets regular all technical requirement, also can be made into be greater than, be less than standard weights rifle body for exercise.During use, select as required to inhale material softer rifle head or metal gun head outwardly, hold javelin center of gravity place and can practise throwing a javelin.Air tube insertion rubber rear head valve port exhaust reduced volume is easy to carry and deposits this javelin.
The present invention compared with prior art tool has the following advantages: a, realize the convenient interchange energy of soft or hard rifle head meet in hard, soft place and all can practise javelin throw on a javelin; B, the soft rifle head of absorbent material immersion liquid pigment, it drops on the function that hard court has mark vestige, is convenient to measure achievement, particularly magic ink within a certain period of time natural evaporation do not affect place environment; C, javelin is made equaled, be greater than, be less than standard weights, can meet the sell demand of strength and speed of exercise; D, the soft rifle head of absorbent material can be avoided hurting sb.'s feelings, and the elastic buffer cushioning effect of landing after the inflation of rifle body can not damaged hard court and rifle body; E, this javelin eliminating gas reduced volume are easy to carry and deposit.

Fig. 1 is that metal gun head of the present invention master outwardly looks section simplified schematic diagram;
Fig. 2 is that water-absorption material spray gun head of the present invention master outwardly looks section simplified schematic diagram;
Fig. 3 is A-A view of Fig. 1.
In figure: 1, head of javelin, 2, front head, 3, back-up ring, 4, support column, 5, rear head, 6, valve port, 7, javelin bar, 8, soft rifle head.
The specific embodiment
The double end inflatable exercise javelin master general in the soft or hard place shown in Fig. 1 and Fig. 2 looks in section simplified schematic diagram, and javelin bar is the rubber tube identical with standard javelin bar external diameter, and its two ends diameter is less than body diameter, is truncated cone shape.In the javelin center of gravity place at this javelin bar middle part, establishing the pipe by rigid material made corresponding with it is support column, and itself and javelin bar inwall are bonding.Annular retaining ring is established at these support column two ends, and its outer ring surface and javelin bar inner surface are bonding.At above-mentioned javelin bar two ends, be respectively equipped with corresponding with them and by end socket before and after the rubber of its closed at both ends, they and javelin bar are bonding, wherein in rear head, establish half open-work that can insert air tube, it is valve port, in front head, establishing opening portion and be cylindrical is conical slotted eye inside, and this slotted eye is corresponding with head of javelin.This metal javelin centriciput is cylinder, and the cone of its one end for being connected as a single entity with it, establishes slotted eye in this head of javelin cylinder other end, in it, can be provided with magic ink.On this groove hole end top, be provided with the lid of being made by rigid foam of its shutoff, i.e. soft rifle head.In lid outside, be provided with outer cover, this outer cover is circular groove shape, and the end is provided with through hole, and perisporium is threaded with head of javelin.
