Abstract
Disclosed is a safe hurdle. A left hurdle frame base is arranged on the ground. Frame rods are telescopic rods, and each telescopic rod is composed of two casing pipes with different diameters. The outer walls of the two casing pipes are respectively provided with a plurality of locating through holes in the direction perpendicular to the axes of the casing sleeves, and locating screws are inserted into the locating through holes in the two casing pipes. One end of one frame rod is connected with the upper surface of the left hurdle frame base through a ball pair, the end, close to the ball pair, on the frame rod is provided with a fixing seat, the outer side of the frame rod and the outer side of the ball pair are sleeved with a reset spring, one end of the reset spring is connected with the fixing seat, and the other end of the reset spring is connected with the left hurdle frame base. The upper ends of the casing pipes at the free ends of the frame rods are connected with one ends of hurdle rods respectively through ball pairs, and the other ends of the hurdle rods are respectively provided with a magnet. The structure of a right hurdle frame and the connecting method of the structure of the right hurdle frame are the same as the structure of the left hurdle frame and the connecting method of the structure of the left hurdle frame respectively, and the magnetic pole of the magnet on the hurdle rod of the left hurdle frame and the magnetic pole of the magnet on the hurdle rod of the right hurdle frame are opposite to each other. The safe hurdle has the advantages of being simple in structure, convenient to use, high in safety, suitable for hurdling beginners and children at young age, and suitable for hurdling popularization.
Description
Technical fieldThe utility model relates to a kind of sports equipment, especially relates to a kind of hurdling.
Background technologyExisting hurdling in the market, mostly be structure as a whole, be widely used among various track and field contest matters, along with hurdle campaign rise at home, the more and more children just begins to contact this motion when going to school, yet existingly hurdle too hardly, be difficult for toppling over, height is shorter and rigidly connect the child who touches hurdle campaign and be easy to when carrying out this motion across hurdle only, thereby tumble injury, the hurdle frame not only trips child, and can also injure child's health, and is very dangerous.
Summary of the inventionThe purpose of this utility model is to provide a kind of simple in structure, and is easy to use, and safe hurdles.
a kind of safe hurdles, it mainly comprises left hurdle frame and right hurdle frame, its left hurdle frame mainly comprises base, hack lever, holder, back-moving spring, railing and magnet, wherein base is placed on ground, described hack lever is the expansion link that the sleeve of two joint different-diameters forms, axis direction perpendicular to sleeve on the outer wall of two joint sleeves is respectively equipped with several positioning through hole, dog screw is inserted in the positioning through hole of two joint sleeves, hack lever one end is connected with left base upper surface by the ball pair, be provided with holder near the secondary end of ball on hack lever, back-moving spring is enclosed within hack lever and is connected with holder with the ball pair outside and one end, an other end is connected with base.The upper end of the free-ended sleeve of hack lever and railing one end connect by the ball parafacies, and an other end of railing is provided with magnet.
The structure of the structure of described right hurdle frame and the connected mode of structure thereof and left hurdle frame is identical with the connected mode of structure, and the magnet magnetic pole on the railing of two the hurdle framves in described left and right is opposite.
During use, with the magnet adsorption on the hurdle frame railing of two of left and right together, if child does not stride across when hurdling, magnet on two railings is subject to external force and is easy to separately, hack lever can be adjusted dump angle by the ball pair, can not trip child, and under the environment of external force, back-moving spring can reset to original position again with hack lever not having, change the height of hurdle frame by dog screw, be applicable to the people of different heights.
Compared with the prior art, the beneficial effects of the utility model are: simple in structure, easy to use, safe, the child that the beginner who is applicable to hurdle and age are little is conducive to the popularization of hurdle campaign.
Description of drawingsFig. 1 is that master of the present utility model looks simplified schematic diagram.
﹠lt, b TranNum="60" ﹠gt, the specific embodiment ﹠lt, / b ﹠gt, in master of the present utility model shown in Figure 1 looks simplified schematic diagram, its left hurdle frame mainly comprises base 1, hack lever 2, holder 3, back-moving spring 4, railing 5 and magnet 6, wherein base is placed on ground, described hack lever is the expansion link that the sleeve of two joint different-diameters forms, axis direction perpendicular to sleeve on the outer wall of two joint sleeves is respectively equipped with several positioning through hole, dog screw 7 is inserted in the positioning through hole of two joint sleeves, hack lever one end is connected with left base upper surface by the ball pair, be provided with holder near the secondary end of ball on hack lever, back-moving spring is enclosed within hack lever and is connected with holder with the ball pair outside and one end, an other end is connected with base.The upper end of the free-ended sleeve of hack lever and railing one end connect by the ball parafacies, and an other end of railing is provided with magnet.
The structure of the structure of described right hurdle frame and the connected mode of structure thereof and left hurdle frame is identical with the connected mode of structure, and the magnet magnetic pole on the railing of two the hurdle framves in described left and right is opposite.
