Description

A kind of folding physical education starting block

Technical field

The utility model relates to a kind of starting block, in particular to a kind of folding physical education starting block.

Background technique

Starting block is a kind of track and field run-up equipment, in all kinds of large-scale games, past, dash all to stand starting. It was once sprint performance stagnation and worried that Australian dash man, which gives up Lille,.He observes kangaroo and has although dragged a sack Son, it is bellied, but it runs more than 70 kilometers per hour, and one step of long-jump is up to 12 meters.It is preceding always first that discovery kangaroo in house Lille runs jump Downwards then body in the wrong springs straight up into the air abdomen ground proximity.Give up Lille and imitate kangaroo, invented crouching start, thus he Marvelous results are created in the Olympic Games in 1896.Later, many sportsmen imitated.If another one sportsman Bu Ke is in starting line On the place squatted down dug a slight shallow hole, a foot puts shallow hole into, and block clearance time foot one is pedaled, and just arrow is generally rushed and penetrated, Achieve achievement of the 100 meter dash less than 10 seconds.After, all runners use crouching start, then track and field Occurs this product of starting block on sports ground.

It carries out needing to carry out run-up when sprint training using starting block on the physical education of existing school, it is existing to help It is longer to run device pedestal, it is extremely inconvenient when carrying, do not have the function of folding, therefore, it is proposed that a kind of folding Physical education starting block.

Utility model content

The main purpose of the utility model is to provide a kind of folding physical education starting blocks, can effectively solve It carries out needing to carry out run-up using starting block when sprint training on the physical education of existing school in background technique, it is existing Starting block pedestal is longer, extremely inconvenient when carrying, and does not have the problem of function of folding.

To achieve the above object, the technical solution that the utility model is taken are as follows:

A kind of folding physical education starting block, including first base, second base, the first framework and the second frame The right end of body, the first base is hinged with second base, the front and back of the second base and first base by first axle Two sidewalls open up it is jagged, the front side wall of the first base and the rear wall of second base be connected separately with the first framework and Step tread plate, the back side installation of the step tread plate are respectively connected on the left of the inner cavity of second framework, first framework and second framework There is a firm shell, the inner cavity of the firm shell is plugged with one end of supporting plate, the other end of two groups of supporting plates and respectively the first framework and the The intracavity bottom of two frameworks connects, and the outer wall of the firm shell is plugged with bolt, the left end of the first base and second base Right end be mounted on handle.

Further, shaft, the bottom of the step tread plate are mounted on the left of the inner cavity of first framework and second framework Portion is set in the outer wall of shaft, and the front side wall of first framework and the rear wall of second framework are mounted on fixed block, described The two sidewalls of fixed block offer limiting slot compatible with notch.

Further, the bottom of two groups of supporting plates passes through the activity of the intracavity bottom of second hinge and the first framework and second framework Connection.

Further, the upper end outer wall of the supporting plate offers threaded hole compatible with bolt.

Further, the bottom of the first base and second base is mounted on anti-skid stud.

Compared with prior art, the utility model has the following beneficial effects:

1. the folding physical education starting block of the utility model, by passing through between first base and second base Hinge hingedly, first base and second base are folded, volume is reduced, thus easy to carry.

2. the folding physical education starting block of the utility model, passes through the first framework and second framework height and bottom Seat height degree is identical, so that two groups of step tread plates and supporting plate can close at respectively in the first framework and second framework, then integrally receives it In first base and second base inner cavity, so that the phenomenon that being convenient for storage and management, avoiding the occurrence of loss.

3. the folding physical education starting block of the utility model, by step tread plate and branch board mount using bolt into Row is firm, so that step tread plate stability is good, is not in shaking phenomenon, shaking is effectively avoided to impact sportsman.

Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

As shown in Figure 1-3, a kind of folding physical education starting block, including first base 1, second base 2, first The right end of framework 4 and second framework 5, the first base 1 is hinged with second base 2, second bottom by first axle 8 Seat 2 and the front and rear sides wall of first base 1 open up jagged 3, after the front side wall and second base 2 of the first base 1 Side wall is connected separately with the first framework 4 and second framework 5, is respectively connected on the left of the inner cavity of first framework 4 and second framework 5 Step tread plate 6, the back side of the step tread plate 6 are equipped with firm shell 7, and the inner cavity of the firm shell 7 is plugged with one end of supporting plate 9, and two The other end of group supporting plate 9 is connected with the first framework 4 respectively with the intracavity bottom of second framework 5, the outer wall grafting of the firm shell 7 There is bolt 11, the left end of the first base 1 and the right end of second base 2 are mounted on handle 10.

Wherein, shaft 14, the bottom of the step tread plate 6 are mounted on the left of the inner cavity of first framework 4 and second framework 5 Portion is set in the outer wall of shaft 14, and the front side wall of first framework 4 and the rear wall of second framework 5 are mounted on fixed block 12, the two sidewalls of the fixed block 12 offer limiting slot 13 compatible with notch 3.

Wherein, the bottom of two groups of supporting plates 9 is living by the intracavity bottom of second hinge 15 and the first framework 4 and second framework 5 Dynamic connection.

Wherein, the upper end outer wall of the supporting plate 9 offers threaded hole 16 compatible with bolt 11.

Wherein, the bottom of the first base 1 and second base 2 is mounted on anti-skid stud 17.

Working principle: in use, limiting slot 13 and the first bottom first with 12 both ends of fixed block at 4 back side of the first framework The notch of 1 side wall of seat is cooperatively connected, so that stable connection, then by the way that the fixed block 12 of 5 front surface of second framework is sharp It is bonded with same procedure and second base 2, is then come out the rotation of step tread plate 6, supporting plate 9 is then inserted into firm shell Then 7 inner cavity is inserted into threaded hole 16 by the outer wall that bolt 11 runs through firm shell 7 and is fastened, so that step tread plate 6 is not Then the phenomenon that will appear shaking, can produce resistance by the anti-skid stud 17 of 2 bottom of first base 1 and second base, provide The power of run-up carries out use, and when not applicable, fixed block 12 is dismantled, then dismantles bolt 11, so that branch Plate 9 is detached from firm shell 7, and two groups of supporting plates 9 and two groups of step tread plates 6 are then closed at 5 inner cavity of the first framework 4 and second framework respectively, Then inner cavity that first framework 4 and second framework 5 are closed to first base 1 and second base 2 respectively, then by first base 1 Doubling is carried out using the activity of first axle 8 with second base 2, so that volume reduces, is then taken using two groups of handles Band, the apparatus structure is simple, practical convenient for operation.
