Description

Safety high jump stand

Technical Field

The utility model relates to a safe high jump stand, and belongs to the technical field of sports goods.

Background

Jumping is a field competition item of track and field sports, and is the movement of a human body jumping cross bar through actions such as running up, jumping off, landing and the like. The equipment that high jump motion used is the high jump frame, and traditional high jump frame comprises the stand of both sides and the horizontal pole between the stand, and in high jump in-process, sportsman if high jump is high inadequately, touches the horizontal pole from the horizontal pole front, and the horizontal pole can take place to drop to judge high jump failure.

The beginner or the student can fall from the upper part of the cross rod to press the cross rod because the beginner or the student does not know the jump collar and the jump time is not well known. Because the horizontal pole can only slide the back and drop, can't directly drop downwards, consequently can cause the horizontal pole to press the bending deformation, because the supporting role of horizontal pole causes personnel to hurt even, makes the beginner produce timidity psychology.

If the elastic band is adopted to replace the cross rod, the situation that the jumping cross rod is bent and deformed and personnel are injured due to the supporting function of the cross rod is avoided, but the elastic band is in binding fixation with the upright post, if the jumping fails, the jumping stand can be pulled down, a certain potential safety hazard exists, the elastic band is adopted to replace the cross rod, and the height measurement of the jumping is inaccurate.

Disclosure of Invention

According to the defects in the prior art, the technical problems to be solved by the utility model are as follows: a safe high jump stand capable of reducing the risk of high jump sports safety is provided.

The utility model relates to a safe high jump stand, which comprises two upright posts and a cross rod between the upright posts, wherein the upright posts are fixed on a base, the upright posts are provided with cross rod supporting devices, the height of each cross rod supporting device is adjustable, each cross rod supporting device comprises a sleeve and a supporting plate arranged on the side wall of the sleeve, the sleeve is sleeved on the upright post, the supporting plates are rotatably connected with the sleeve, and the supporting plates are in a horizontal state under the action of an elastic mechanism and can be turned downwards when stressed.

Under normal state, the supporting plate can support the cross rod, and when the cross rod is touched by the front surface during high jump, the cross rod can fall off; if touch the horizontal pole from above, when horizontal pole atress pushes down, because horizontal pole both ends are used in the backup pad, as the direction that the arrow shows in fig. 5, backup pad atress is the upset downwards, and the horizontal pole can directly drop down, can not bear sportsman's belly or waist, has avoided bending deformation with the horizontal pole, has more avoided personnel to be injured, reduces the high jump risk of movement.

Wherein, the backup pad be connected with ascending riser, backup pad and riser's combination is L shape. The vertical plate plays a limiting role, so that the supporting plate cannot tilt upwards after being in a horizontal state.

Preferably, the elastic mechanism is a torsion spring, the torsion spring is coiled on the shaft, two support legs of the torsion spring are respectively abutted with the outer wall of the sleeve and the bottom surface of the support plate, and the shaft is connected with the support plate and the sleeve.

Preferably, the cross bar supporting device is locked and fixed through plum blossom locking screws arranged on the side wall of the sleeve, and the structure is simple.

Preferably, the stand is detachably connected with the base, so that the stand is convenient to split and transport.

Further, the upright posts are inserted into the vertical sleeves of the base and locked and fixed through the locking device.

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

the safe high jump stand is simple in structure and convenient to manufacture. Compared with the conventional jumping stand, the transverse rod can only slide backwards and fall, when the transverse rod is pressed downwards under the force, the supporting plate is stressed to turn downwards, and the transverse rod can directly fall downwards, so that the condition that the transverse rod is bent and deformed is avoided, the condition that personnel are injured is avoided, and the risk of jumping is reduced.

Detailed Description

The utility model will be further illustrated with reference to specific examples.

However, the description of the present utility model is merely an embodiment of a structural or even functional description, and the scope of the claims of the present utility model is not limited by the embodiments described herein.

For example, the embodiments may have various modifications and various forms, and it is to be understood that the scope of the claims of the present utility model includes equivalents capable of realizing the technical idea.

As shown in fig. 1 to 8, the present embodiment is realized by the following technical scheme: the high jump stand comprises two upright posts 2 and a cross rod 3 between the upright posts 2, wherein the upright posts 2 are fixed on a base 1, and a cross rod supporting device 4 is arranged on the upright posts 2.

The rail support means 4 comprises a sleeve 41, a quincuncial locking screw 42, a support plate 43, a shaft 44 and a torsion spring 45. The sleeve 41 is sleeved on the upright post 2, the supporting plate 43 is rotationally connected with the sleeve 41 through the shaft 44, the torsion spring 45 is coiled on the shaft 44, two support legs of the torsion spring 45 are respectively abutted with the outer wall of the sleeve 41 and the bottom surface of the supporting plate 43, the supporting plate 43 is in a horizontal state under the action of the torsion spring 45, the supporting plate 43 can be turned downwards when stressed, and the supporting plate 43 is used for placing the supporting cross rod 3.

The supporting plate 43 of the embodiment is connected with an upward vertical plate 431, the combination of the supporting plate 43 and the vertical plate 431 is L-shaped, and the vertical plate 431 plays a limiting role, so that the supporting plate cannot tilt upwards after being in a horizontal state, and is stable.

The rail support 4 is locked by means of quincuncial locking screws 42 provided on the side walls of the sleeve 41, whereby the height of the rail support 4 is adjustable.

The stand 2 is detachably connected with the base 1, and the stand 2 is inserted into a vertical sleeve of the base 1 and is locked and fixed through another locking screw, so that the stand is convenient to assemble, disassemble and transport.
