Abstract
The utility model relates to a high jump stand for physical training, in particular to a high jump stand without crossbar. The high jump stand without crossbar comprises a left support (1), a right support (2), a left support base (3), a right support base (4), a switch (7) and nuts (9), wherein, the lower parts of the left support and the right support are respectively fixed on the left support base and the right support base vertically, and the switch is arranged on the left support. The high jump stand without crossbar also comprises a ray emitter (5) and a ray sensor (6), wherein, the ray emitter (5) and the ray sensor (6) are respectively fixed on the upper part of the left support and the right support by nuts; the ray emitter corresponds to the ray sensor; the switch is connected with the ray emitter and the ray sensor by conducting lines. The utility model replaces the high jump crossbar with the ray emitter and the ray sensor, when an obstacle exists between the ray emitter and the ray sensor, the ray is disconnected to make the buzzer in the ray sensor buzz. The utility model solves the problems of the accuracy and the safety of the height measurement of the high jump stand.
Description
Technical field
The utility model relates to the jumping stand that athletic training is used, and relates in particular to a kind of no cross bar jumping stand.
Background technology
At present, athletic training, the match usefulness jumping stand, all be the cross bar of the parallel placement of sustained height between the support of the right and left, when the high jumper train, when competing, cross the bar and cross bar is not touched down, then the placement of cross bar highly is exactly athletic achievement.Jumping stand has although it is so used for many years, but but has some problems: highly accuracy of Ce Lianging and safety issue.Because the deadweight of cross bar itself, the both sides of cross bar and center must be at sustained heights, between have certain error, in order to reduce error, must limit to some extent the length and the weight of cross bar; The sportsman can drop on the mat after jumping, if cross corresponding height cross bar is not touched down, and then cross bar can fall simultaneously with the sportsman, so just has certain insecurity.
Summary of the invention
The utility model has overcome original jumping stand will place cross bar, has the defective of safety factor scarcely simultaneously, and a kind of no cross bar jumping stand is provided.This no cross bar jumping stand substitutes cross bar by adopting light emitters, has solved the accuracy of jumping stand height measurement and the problem of security.
The utility model is to realize like this, a kind of no cross bar jumping stand, comprise left socle, right support, left socle base, right support base, switch and nut, left socle and right support bottom difference vertical fixing are on left socle base and right support base, switch is loaded on the left socle, this no cross bar jumping stand also comprises light emitters, light sensor, light emitters and light sensor are fixed in the top of left socle and right support respectively with nut, light emitters is corresponding with light sensor, and switch connects light emitters and light sensor with lead;
Above-mentioned a kind of no cross bar jumping stand, this no cross bar jumping stand also comprises bottom bar, the two ends of bottom bar connect left socle base and right support base respectively;
Above-mentioned a kind of no cross bar jumping stand, left socle, right support and bottom bar are adjustable length.
Operation principle of the present utility model is: the principle of utilizing light straightline propagation, substituted jumping bar with light emitters and light sensor, when between light emitters and light sensor barrier being arranged, light disconnects the buzzer call that makes in the light sensor.The accuracy of jumping stand height measurement and the problem of security have been solved.
Description of drawings
Fig. 1 is a kind of no cross bar jumping stand schematic diagram.
Wherein, 1 is left socle, and 2 is right support, and 3 is the left socle base, and 4 is the right support base, and 5 is light emitters, and 6 is light sensor, and 7 is switch, and 8 is bottom bar, and 9 is nut.
The specific embodiment
The specific embodiment of the present utility model is provided by accompanying drawing.
Referring to shown in Figure 1, a kind of no cross bar jumping stand, comprise left socle 1, right support 2, left socle base 3, right support base 4, switch 7 and nut 9, left socle 1 and right support 2 bottoms difference vertical fixing are on left socle base 3 and right support base 4, switch 7 is loaded on the left socle 1, this no cross bar jumping stand also comprises light emitters 5, light sensor 6, light emitters 5 and light sensor 6 are fixed in the top of left socle 1 and right support 2 respectively with nut 9, light emitters 5 is corresponding with light sensor 6, and switch 7 connects light emitters 5 and light sensor 6 with lead; This no cross bar jumping stand also comprises bottom bar 8, and the two ends of bottom bar 8 connect left socle base 3 and right support base 4 respectively; Left socle 1, right support 2 and bottom bar 8 are adjustable length.In the present embodiment, open switch 7, make light emitters 5 and light sensor 6 work, and become a loop; Owing to left socle 1 and right support 2 are adjustable length and contain corresponding scale, can reach the height of sportsman's jump by adjusting left socle 1 and right support 2 simultaneously.When the sportsman jumps, jump when only being somebody's turn to do height, can run into the light of light emitters 5 emissions, light is disconnected, the buzzer in the light sensor 6 will pipe like this.
