Description

Hurdle is striden in track and field sports

Technical Field

The utility model relates to a hurdle is striden in track and field sports.

Background

The hurdles comprise a high jump hurdle and a running hurdle, and are common sports items of students. And hurdles are an important facility. Generally, a hurdle comprises two vertical bars and a cross bar disposed between the two vertical bars. The cross rods are arranged on the two vertical rods or are integrally connected with the vertical rods. In order to stably place the vertical rods, the lower parts of the vertical rods are also provided with bases, and a support plate is arranged between the two vertical rods for connection. However, the base is long, and the support plate connects the two vertical rods into a whole, so that the hurdle occupies a large space when being stored, and is inconvenient to arrange. And the common hurdle frame base length of striding can not be adjusted, when being used for the high jump training, when striding the high of hurdle frame higher, can't lengthen the base with stability increase correspondingly, and make into longer structure with the base correspondingly, will greatly increased stride the shared space of hurdle, be not convenient for deposit.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a hurdle is striden in track and field sports.

The utility model discloses a following technical scheme can realize.

The utility model provides a hurdle is striden in track and field sports, erect the frame including breast board and two, on the breast board set up and erect the frame with two, erect the frame bottom and articulate separately has a base, erect the articulated position below of frame and base and still be equipped with the tower and detain B and be connected, two perpendicular frame bottoms are passed through the extension board and are connected, and the extension board is two sections, and the one end of two sections extension boards is connected by the tongue-and-groove mutually, and the other end erects the frame with one separately and articulates, and the extension board still is equipped with the tower with the below of the articulated position of erecting the frame and detains.

Because the support plate is of a two-section structure and is connected by the mortises, the two support plates are mutually clamped when in assembly and use, the stability of the hurdle frame is kept, and the two vertical frames are mutually independent after being disassembled, so that the hurdle frame is convenient to carry; and the vertical frame, the support plate and the base can be folded through hinging, so that the space occupation is reduced.

The base comprises a sliding rod and a sleeve, the sliding rod extends into the sleeve, a sliding block is arranged in the sleeve, and the sliding block is connected with the end portion of the sliding rod. Through this setting for the length of base is adjustable, can prolong the base with the increase stability correspondingly when striding hurdle highly higher. Furthermore, the rear end of the sleeve is also provided with a first end cover, so that sundries can be prevented from entering the sliding blocks, and the pair of sliding blocks of the end cover can limit the sleeve to impact the vertical frame. Furthermore, the front end of the sleeve is also provided with a second end cover, the second end cover is matched with the slide rod through a through hole, a guiding effect is achieved, meanwhile, the two pairs of slide blocks of the end covers generate a limiting effect, and the slide blocks are prevented from being pulled out forcefully when the base is prolonged.

Furthermore, the end part of the sliding rod is also provided with a thread head, and the sliding rod is in threaded connection with the sliding block. Through threaded connection, be detachable construction between sleeve pipe and the slide bar, the transport of being convenient for has further reduced the occupation of space. The thread head is provided with a chamfer, the width of the chamfer is not less than two times of the height of the thread and not less than 3mm, and the thread head is aligned to the sliding block when the thread head is convenient to install.

The beneficial effects of the utility model reside in that:

to sum up, compared with the prior art, the utility model, have following advantage: because the support plate is of a two-section structure and is connected by the mortises, the two support plates are mutually clamped when in assembly and use, the stability of the hurdle frame is kept, and the two vertical frames are mutually independent after being disassembled, so that the hurdle frame is convenient to carry; the vertical frame, the supporting plate and the base are foldable through hinging, so that the space occupation is reduced.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1-3, the structure of the present invention is schematically shown as follows:

the utility model provides a hurdle is striden in track and field sports, erect frame 2 including breast board 1 and two, on breast board 1 set up and two erect frame 2, erect 2 bottoms of frame and articulate separately have a base 3, erect frame 2 and still be equipped with the tower below the articulated position of base 3 and detain B304 and be connected, two erect 2 bottoms of frame and pass through extension board 4 and connect, extension board 4 is two sections, and the one end of two sections extension boards 4 is connected by the tongue-and-groove mutually, and the other end erects frame 2 with one separately and articulates, and extension board 4 still is equipped with the tower below the articulated position of erecting frame 2 and detains A401 and is connected.

Because the support plate 4 is of a two-section structure and is connected by the tongue-and-groove, when the hurdle is assembled and used, the two support plates 4 are mutually clamped, the stability of the hurdle frame is kept, and the two vertical frames 2 are mutually independent after being disassembled, so that the hurdle is convenient to carry; and the vertical frame 2, the support plate 4 and the base 3 can be folded through hinging, so that the space occupation is reduced.
