Abstract

The utility model discloses a cross bar of a jumping standard, belonging to the technical field of sport equipments. When the cross bar of the jumping standard in the utility model is used, the cross bar automatically breaks when meeting impact and then is connected to restore to be used; a trainer is difficult to damage by a broken cross bar unit, so that the cross bar can satisfy normal sports teaching and training requirements. The cross bar of the jumping standard comprises a multi-section cross bar unit, wherein opposite surfaces of the neighbor two cross bar units are respectively provided with a countersink; the neighbor two cross bar units are connected by one leaf spring in two countersinks; the opposite surfaces of the neighbor two cross bar units are respectively fixed with an annular magnetic piece; the neighbor two cross bar units are connected by suction of two annular magnetic pieces to form an assembled cross bar of the jumping standard; two ends of the assembled cross bar of the jumping standard are arranged on supporting frames of two supporting vertical columns of the jumping standard; and the leaf spring is an arch shape. The cross bar of the jumping standard is used for sports teaching and training.

Description

A kind of jumping bar

Technical field

The utility model belongs to the sports equipment technical field, is a kind of jumping stand specifically.

Background technology

Existing jumping bar is an integral structure, when the trainer when carrying out high jump training, if health often collides cross bar; Cross bar is prone to be bent, fracture, and because of the length of cross bar is generally 3.5 meters or 4 meters, length is longer; The cross bar that is fractureed is being hindered the trainer easily; Simultaneously, the cross bar that is fractureed can't continue to use again, influences normal physical education and training.

The utility model content

The purpose of the utility model provides a kind of jumping bar, and this jumping bar is met the bump automatic disconnection, and can be connected recovery usefulness more in use, and the cross-bar unit of disconnection is not easy to injure the trainer, can satisfy the needs of normal physical education and training.

A kind of jumping bar; Described jumping bar comprises the more piece cross-bar unit; Be processed with counterbore respectively on the opposite face of adjacent two joint cross-bar unit, adjacent two joint cross-bar unit connect through a spring leaf that is arranged in two counterbores, are fixed with an annular magnetic sheet respectively on the opposite face of adjacent two joint cross-bar unit; Adjacent two joint cross-bar unit are inhaled connection mutually through two annular magnetic sheet magnetic; And constitute the combined type jumping bar, and the two ends of combined type jumping bar are arranged on the carriage of two support posts of jumping stand, and shape of spring plate is an arch.

The jumping bar of the utility model is owing to comprise the more piece cross-bar unit, and adopts fabricated structure, when trainer's health collides certain joint cross-bar unit or connects end face; Collision is initial, connects between two annular magnetic sheets on the end face inconsistent phenomenon can take place, and spring leaf is under the effect of elastic force; One end can skid off in the counterbore, causes these two annular magnetic sheets to break off rapidly, because the length of cross-bar unit will be far smaller than the length of integral type cross bar; Even cross-bar unit slips down, can not break yet, and be not easy to injure the trainer; Cross-bar unit combination back is indeformable, can reuse, and has satisfied the needs of normal physical education and training.

Description of drawings

Fig. 1 is a kind of jumping bar front view of the utility model;

Fig. 2 is Fig. 1 left view;

Fig. 3 is the front view that adjacent two joint cross-bar unit 1 are connected.

Wherein, cross-bar unit 1, counterbore 2, spring leaf 3, annular magnetic sheet 4, support post 5, carriage 6.

The specific embodiment

The specific embodiment one: shown in Fig. 1～3; A kind of jumping bar, described jumping bar comprises more piece cross-bar unit 1, is processed with counterbore 2 respectively on the opposite face of adjacent two joint cross-bar unit 1; Adjacent two joint cross-bar unit 1 connect through a spring leaf 3 that is arranged in two counterbores 2; Be fixed with an annular magnetic sheet 4 respectively on the opposite face of adjacent two joint cross-bar unit 1, adjacent two joint cross-bar unit 1 are inhaled connection mutually through two annular magnetic sheet 4 magnetic, and constitute the combined type jumping bar; The two ends of combined type jumping bar are arranged on the carriage 6 of two support posts 5 of jumping stand, spring leaf 3 be shaped as arch.

Claims

1. jumping bar; It is characterized in that: described jumping bar comprises more piece cross-bar unit (1); Be processed with counterbore (2) respectively on the opposite face of adjacent two joint cross-bar unit (1), adjacent two joint cross-bar unit (1) connect through a spring leaf (3) that is arranged in two counterbores (2), are fixed with an annular magnetic sheet (4) respectively on the opposite face of adjacent two joint cross-bar unit (1); Adjacent two joint cross-bar unit (1) are inhaled connection mutually through two annular magnetic sheets (4) magnetic; And constitute the combined type jumping bar, the two ends of combined type jumping bar are arranged on the carriage (6) of two support posts (5) of jumping stand, spring leaf (3) be shaped as arch.
