Description
Technical field
The utility model relates to a kind of sports apparatus, particularly a kind of volleyball smash exercising machine.
Background technology
The volleyball smash exercise is an important content in the volleyball training, in order to let the practitioner carry out the volleyball smash exercise, in physical education, has occurred many volleyball smash exercising machines at present.But more existing volleyball smash exercising machines in use exist height adjustment inconvenient, can not satisfy two practitioners and practise slam-shot simultaneously, and can't adapt to the problem that different height practitioners require.
Summary of the invention
The purpose of the utility model provides a kind of volleyball smash exercising machine, and this volleyball smash exercising machine height adjustment is convenient, when satisfied two practitioners practise spiking simultaneously, also can satisfy different height practitioners' requirement.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
A kind of volleyball smash exercising machine, described exercising machine comprises base, the lower end of cover is rotationally connected in the middle part of base and the screw thread; Driven bevel gear is provided with centre bore, and cover is fixed in the centre bore of driven bevel gear in the screw thread, initiatively conical gear and driven bevel gear engagement; Initiatively conical gear is installed on the gear shaft, and the two ends and the support of gear shaft are rotationally connected, and the lower end and the base of support are connected; Gear shaft is provided with the annulus cover, and the annulus collar is enclosed within on the screw mandrel, and the lower end of screw mandrel is connected through matching thread with the interior cover of screw thread; One end of gear shaft is fixed with hand crank, and an end of the upper end of screw mandrel sidewall and two cross bars is connected, and the bottom of the other end of two cross bars respectively is connected through an elastic rubber band and vollyball; 180 ° of settings apart between two cross bars, two one high and one low settings of cross bar.
Cross bar has the pipe that externally threaded whippletree and an end have internal thread by an end and forms, and described whippletree and described pipe are through being threaded.
The adjustable height of the volleyball smash exercising machine of the utility model can be according to the height of practitioner's height adjustment cross bar; Two one high and one low settings of cross bar can be satisfied practitioner's individual demand.In addition,, make two people can carry out knock simultaneously, improved practitioner's training effectiveness owing to be provided with two cross bars.The volleyball smash exercising machine of the utility model not only is adapted at using in the physical education, also is fit to vast vollyball fan and uses.
When needs adjustment cross bar height, only with hand rotates hand crank, and conical gear rotates thereby drive initiatively; Because initiatively conical gear and driven bevel gear engagement is rotated thereby drive driven bevel gear, because cover is fixedly connected with driven bevel gear in the screw thread; Thereby cover cast in the drive screw thread; Because the interior cover of screw thread is connected through matching thread with screw mandrel, finally drives screw mandrel and move again, realized the adjustment of cross bar height thus along putting down in the screw thread.In addition, for improving the whole stability of volleyball smash exercising machine, preferably base and ground are fixed during use.
Description of drawings
Fig. 1 is the front view of a kind of volleyball smash exercising machine of the utility model.
Wherein, cover 2, driven bevel gear 3, centre bore 4, active conical gear 5, gear shaft 6, support 7, annulus cover 8, screw mandrel 9, cross bar 10, elastic rubber band 11, vollyball 12, whippletree 13, pipe 14, hand crank 15, reinforcement gusset 16 in base 1, the screw thread.
The specific embodiment
As shown in Figure 1, a kind of volleyball smash exercising machine, described exercising machine comprises base 1; The lower end of cover 2 is rotationally connected in the middle part of base 1 and the screw thread, and driven bevel gear 3 is provided with centre bore 4, and cover 2 is fixed in the centre bore 4 of driven bevel gear 3 in the screw thread; Initiatively conical gear 5 meshes with driven bevel gear 3, and initiatively conical gear 5 is installed on the gear shaft 6, and the two ends of gear shaft 6 and support 7 are rotationally connected; The lower end of support 7 and base 1 are connected, and gear shaft 6 is provided with annulus cover 8, and annulus overlaps 8 ring sets on screw mandrel 9; Cover 2 is connected through matching thread in the lower end of screw mandrel 9 and the screw thread; One end of gear shaft 6 is fixed with hand crank 15, and the upper end of screw mandrel 9 sidewalls and an end of two cross bars 10 are connected, and the bottom of the other end of two cross bars 10 respectively is connected through an elastic rubber band 11 and vollyball 12; 180 ° of settings apart between two cross bars 10, two cross bar 10 one high and one low settings; Cross bar 10 has the pipe 14 that externally threaded whippletree 13 and an end have internal thread by an end and forms, and described whippletree 13 and described pipe 14 be through being threaded, and makes the adjustable length of cross bar 10, thereby satisfies practitioner's individual demand.
Firm in order to guarantee lever 10, between lever 10 and screw mandrel 9, increased reinforcement gusset 16.
