Background technology
Football is people's favorite exercise, and people are constantly improving football doorframe.On November 24th, 2010, application number was that 201020139571.0 innovation and creation disclose a kind of football doorframe; This football doorframe is except having two root posts and crossbeam; Also have ray structure, console switch during use can let the light emitting diode on the steel pipe send light; Make football doorframe glittering, increase the appreciation effect of football match.On October 5th, 2011, application number was that 201120082593.2 innovation and creation disclose a kind of football door with slideway; This football door; Comprise the football doorframe frame; And be located at the net or the ball plate of football doorframe frame rear side, the bottom of said football doorframe frame is provided with a slideway at least, oblique left side of described slideway or right side.These innovation and creation since be provided with in the bottom can an oblique side slideway, football is launched into after the football door, can slide to wherein left side or right side automatically, help the recovery of football, reduce and unnecessaryly in the motion pick up the ball action.But slideway one end of an oblique side is higher than the other end, if when football is gone into the goal with pasting, slideway can influence crossing the threshold of football.In addition, football doorframe of the prior art can not change the doorframe width, when the pitch less or play football fewer in number the time, people hope to have a kind of football doorframe that can change the doorframe width.
The utility model content
The purpose of the utility model provides a kind of football doorframe, and this football doorframe can change the doorframe width.
The scheme that the utility model solve the technical problem is: a kind of football doorframe, comprise two montants, first cross bar and second cross bar, and first cross bar is arranged on the top of montant; Second cross bar is positioned at the rear of first cross bar, and said first cross bar comprises the first thick bar and the first thin bar, the first thick bar hollow; The first thin bar is inserted in the first thick bar of hollow; Said second cross bar comprises the second thick bar and the second thin bar, the second thick bar hollow, and the second thin bar is inserted in the second thick bar of hollow.
Through adjusting the length that thin bar is positioned at thick bar, can realize changing the function of football doorframe width.
As further technical scheme, the equal in length of the said first thick bar and the first thin bar, the equal in length of the said second thick bar and the second thin bar.
As further technical scheme again, the below of said second cross bar is provided with the 3rd cross bar, a little higher than ground of the height of the 3rd cross bar, and the 3rd cross bar comprises the 3rd thick bar and the 3rd thin bar, the 3rd thick bar hollow, the 3rd thin bar is inserted in the 3rd thick bar of hollow.
After the 3rd cross bar is set, can on the basis of original net, add one deck net in the bottom of football doorframe, low back, one deck net front of bottom is high, and when football is gone into behind the door, football can be rolled into the front automatically, makes things convenient for the goalkeeper to pick up ball.
As technical scheme further, two end points places of said the 3rd cross bar respectively are provided with a support bar, and an end of support bar is higher than the other end, and the higher end of support bar equates with the height of the 3rd cross bar.
Support bar is that one deck net of bottom provides support, and conveniently is fixed on one deck net of bottom on the football doorframe.
As further technical scheme, the bottom of said montant is provided with base.
Base has increased the steadiness of football doorframe, and the football doorframe of adjusting width can be out of shape easily.
In sum, the utlity model has simple in structure, diverse in function, easy to operate advantage.
The specific embodiment
As shown in Figure 1, a kind of football doorframe comprises two montants 1, first cross bar and second cross bar, and the bottom of montant 1 is provided with the top that base 6, the first cross bars are arranged on montant 1, and second cross bar is positioned at the rear of first cross bar.First cross bar comprises the first thick bar 21 and first thin bar 22, the first thick bar 21 hollows, and the first thin bar 22 is inserted in the first thick bar 21 of hollow, the equal in length of the first thick bar 21 and the first thin bar 22.Second cross bar comprises the second thick bar 31 and second thin bar 32, the second thick bar 31 hollows, and the second thin bar 32 is inserted in the second thick bar 31 of hollow, the equal in length of the second thick bar 31 and the second thin bar 32.The below of second cross bar is provided with the 3rd cross bar; The a little higher than ground of the height of the 3rd cross bar, the 3rd cross bar comprise the 3rd thick bar 41 and the 3rd thin bar 42, the three thick bar 41 hollows; The 3rd thin bar 42 is inserted in the 3rd thick bar 41 of hollow, the equal in length of the 3rd thick bar 41 and the 3rd thin bar 42.Two end points places of the 3rd cross bar respectively are provided with a support bar 5, and an end of support bar 5 is higher than the other end, and support bar 5 higher ends equate with the height of the 3rd cross bar.
