Abstract

The utility model relates to a volleyball combination trainer comprising a box-shaped base, wherein an upright column is inserted and fixedly arranged by virtue of a round hole which is formed in the center of the box-shaped base; the upright column is of a telescopic sleeve structure; the top end of the upright column is symmetrically connected with two cross rods by virtue of a T-shaped connector; a plurality of hanging hooks are arranged on each cross rod, and are fixedly connected with a net bag by virtue of elastic ropes; volleyballs are filled in the net bag; reserved lengths of the elastic ropes connected with the plurality of hanging hooks are different so as to form volleyball training groups with different hanging heights; a pair of built-in rubber wheels are fixedly arranged on one side of the inner part of the box-shaped base by virtue of a wheel carrier; built-in weight boxes are arranged on two sides of the box-shaped base; a non-slip mat is adhered to the bottom of the box-shaped base. The volleyball combination trainer disclosed by the utility model is simple in structure and simple and convenient in height adjustment; practicers can better grasp the ball touch time and different ball hitting points in a volleyball training process with continuously different heights so as to achieve the aim of enhancing the training density within an effective training time.

Description

A kind of vollyball combined exercise device

Technical field

The utility model relates to a kind of athletic training equipment, particularly a kind of for practising the combined exercise device of vollyball pass and dig.

Background technology

Pass and dig are the basic exercise projects that must grasp in volleyball movement project, and the key technology main points of pass and dig are to grasp " buffering firmly " that hand-type, striking point on the ball and finger are accurately coordinated in contacting vollyball process with wrist in the process of repeating, to reduce held ball or error as far as possible.Current traditional pass and dig exercise to be adopted to throwing with from slowball, such exercise is usually because toss or reception error must be picked up ball repeatedly, the tactile ball number of times that made the minimizing of practitioner within effective training time, minority school is furnished with vollyball exercising machines on the other hand, this class exercising machine is often the single ball exercise under single height, exercise mode is single, Height Adjustment inconvenience, thus affect whole practice effect.

Summary of the invention

For addressing the above problem, it is a kind of simple in structure that the utility model provides, the convenient vollyball combined exercise device that is applicable to pass and dig regulating.For achieving the above object, the utility model comprises: box bed, the circular hole of opening by the center of described box bed inserts and is installed with column, column is extendable sleeve structure, column top is by two cross bars of the symmetrical connection of T junction, on cross bar, be installed with some hooks, hook is fixedly connected with the string bag by elastic threads, and vollyball is housed in the string bag; The length in reserve of the elastic threads connecting on some hooks is not identical, forms the volleyball practice group of different suspension heights: the inner side of described box bed fixedly mounts a pair of built-in rubber tire by wheel carrier; On box bed, both sides are provided with built-in ballast box; The bottom of box bed is pasted with slipmat.

Compared with prior art, the utlity model has following advantage:

The utility model proceeds to common vollyball by the string bag, without the higher special use lob of price, easy to use.

The utility model height regulates simple, according to practitioner's height, can by column node upper spring latch and elastic threads length in reserve, realize volleyball practice height respectively regulates, adopt box bed, and by the rubber tire of installing on box bed, indoor and outdoor environment all can be installed and used.The utility model has not only effectively been avoided the single training method of traditional volleyball practice mode, and allow practitioner in the vollyball combined exercise process of continuous differing heights, better hold and touch ball opportunity and different striking point on the ball, buffering strength part when passing or setting up in order to know from experience, realization is effectively strengthening exercise density in practice periods, makes practitioner grasp as early as possible pass and dig technical key point.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Fig. 2 is the structure for amplifying schematic diagram of built-in rubber tire in the utility model.

The specific embodiment

See figures.1.and.2, a kind of vollyball combined exercise device, comprise: box bed 1 adopts the iron plate welding that thickness is 2.0mm to make, the circular hole of opening by the center of described box bed 1 inserts and is installed with column 2, column 2 is extendable sleeve structure, column 2 adopts three-section type extendable sleeve structure, between upper joint telescopic tube and lower joint telescopic tube, on column node, adopts night bolt to be located by connecting.

Column 2 tops are by two cross bars 4 of T junction 3 symmetrical connections, between T junction 3 and column 2, cross bar 4 for being threaded, on cross bar 4, be installed with some hooks, hook is fixedly connected with the string bag 6 by elastic threads 5, in the string bag 6, vollyball is housed, the length in reserve of the elastic threads 5 connecting on some hooks is not identical, forms the volleyball practice group of different suspension heights; The inner side of described box bed 1 is by a pair of built-in rubber tire 8 of wheel carrier 7 fixed installation, and it is attractive in appearance, safe, laborsaving that wheel carrier 1 is arranged on inner side; On box bed, both sides are provided with built-in ballast box 9, can place scrap iron piece, discarded iron ball in built-in ballast box 9; The bottom of box bed is pasted with slipmat, and slipmat adopts EVA sponge anti-slip material.

During use, first vollyball is packed into the string bag 6, and by elastic threads 5, the string bag 6 is tightened, the string bag 6 is close on vollyball, then the other end of elastic threads 5 is tied up to the some hooks on cross bar 4, according to practicing practitioner's height, elastic threads 5 is reserved different length, forms the volleyball practice group of different suspension heights.

Adjusting according to actual needs column height, by the night bolt on lower pillar stand node, after Height Adjustment is suitable, is that column height is fixed after trip spring latch again, and regulative mode is easy, fast, makes the volleyball practice group hanging be placed in suitable height.Can not only effectively avoid the single of traditional volleyball practice mode, and allow practitioner in the vollyball combined exercise process of continuous differing heights, better hold and touch ball opportunity and different striking point on the ball, buffering strength part when passing or setting up in order to know from experience, realization is effectively strengthening exercise density in practice periods, makes practitioner grasp as early as possible pass and dig technical key point.
