Description

A kind of combination type football corner flag

Technical field

This utility model belongs to sports equipment field, is specifically related to a kind of combination type football corner flag.

Background technology

In football match, all plug a corner flag at four angles in football pitch, the knot of the most conventional corner flag Structure includes flagpole, and the top of flagpole is provided with flag face, and the bottom rigid at flagpole connects grounding rod. During use, grounding rod being directly inserted in the subsurface in football pitch, corner flag is secured on football pitch.

The corner flag of said structure has the drawback that: owing to flagpole and grounding rod are to be rigidly connected, at football In match, athlete's imprudence strikes flagpole, and corner flag will be knocked down, even fractures, and needs work Personnel again prop up or change corner flag.

For the shortcoming of above-mentioned corner flag, in prior art the existing root and grounding rod being improved to flagpole it Between connected by spring, make flagpole hit curved after can automatically recover vertical.But above-mentioned improvement still has deficiency Part: flagpole is overall relatively stock, it still may be made to fracture during the games, enter during fierce collision And athletic health may be damaged, such as, when striving for the ball ball during the games, if athlete is oblique Downwardly direction and flagpole end relatively noticeable effort, the spring being now placed in root has little time deformation, then flag Bar is understood itself and may be fractureed because bearing large force, and athlete itself is answered back to by flagpole end, may be subject to Wound；Only one of which root spring, cushioning effect is limited, relatively during noticeable effort, flagpole may be made from the ground It is pulled up；Flagpole is longer, is stored inconveniently in less space.

Utility model content

For deficiency of the prior art, this utility model provides a kind of combination type football corner flag, and it is difficult to Fractureing, the injury being likely to result in athlete is little, detachably, it is simple to deposit.

The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of combination type football corner flag, Including upper flagpole, lower flagpole and grounding rod, the upper end of described upper flagpole connects flag face, described upper flagpole The upper end of lower end and described lower flagpole removably connected by the first elastic joint part, described lower flagpole Lower end is removably connected by the second elastic joint part with the upper end of described grounding rod.

On the basis of technique scheme, this utility model can also do following improvement.

Further, described first elastic joint part is made up of spring one and two screws one, described spring one Two ends up and down be respectively fixedly connected with a described screw one, the lower end of described upper flagpole and lower flagpole upper End is provided with the female thread matched with described screw one, and the two ends up and down of described spring one are passed through respectively Described screw one is connected with the lower end of described upper flagpole and the threaded upper ends of lower flagpole.

Further, described second elastic joint part by spring two and fixes two groups of the screw being connected with its upper end Becoming, the lower end of described lower flagpole is provided with the female thread matched with described screw two, described spring two Being threadeded with the lower end of described lower flagpole by described screw two in upper end, described first elastic joint part leads to The upper end of the lower end and described grounding rod of crossing described spring two is fixed and is connected.

Above two is further improved, rise elastic reaction for spring, according to the intensity of flagpole material, The spring of different thicknesses can be selected flexibly；Connected mode between parts is threaded, is threaded to The common mode that removably connects, it is firm to connect, and processing is simple.

Further, described grounding rod is the bullet that thick lower end, upper end that rustless steel is made is thin.Bullet Design is easy to grounding rod is inserted ground.

Further, described upper flagpole and lower flagpole are made by rigid plastics.Plastics flagpole moderate strength and The relatively common steel flagpole of weight wants light, it is simple to carry.

Further, the length of described upper flagpole and lower flagpole is equal.Upper flagpole is equal with lower flagpole length, I.e. first elastic joint part is arranged on the middle part of whole flagpole, when athlete strives for the ball ball near corner flag never Equidirectional time flagpole is had active force, the upper and lower of flagpole can bend to different directions, and flagpole is difficult to Fracture.

The beneficial effects of the utility model are: have the first elastic joint part and the second elastic joint part, when When flagpole is by the external forces of different directions, upper flagpole and lower flagpole can bend to different directions to subtract Light folding force, prevents flagpole from fractureing；First elastic joint part and the second elastic joint part can play dual slow Punching effect, can alleviate, when large force acts on the moment on flagpole, the active force that grounding rod is subject to, prevent flag Bar is pulled up；Use removably connects mode, and the several part of the detachable one-tenth of whole flagpole can leave in relatively In little space, in order to carry.

Accompanying drawing explanation

The structural representation of a kind of combination type football corner flag that Fig. 1 provides for this utility model；

In accompanying drawing, the list of parts representated by each label is as follows:
