Description

A portable infrared sensor badminton block

technical field

The invention relates to a sporting goods, in particular to a portable infrared-ray induction badminton block.

Background technique

Although common badminton courts do not have the problem of block shaking, they cannot be moved and can only be built in open squares, which greatly limits the conditions for people to play ball games. With the advancement of urbanization, urban community life will occupy the main body of society, and the area occupied by human settlement activities will become less and less. The ever-decreasing fitness area seriously cannot meet people's needs for sports venues, which will inevitably greatly weaken the feasibility and entertainment of a series of sports activities such as badminton. When performing badminton, if there is no blocking, this will cause various fouls when playing. Moreover, the judging standard of badminton is usually determined by whether the ball passes the net. Without blocking, there is no way to better count the score.

Contents of the invention

In order to overcome the deficiencies of the above technologies, the present invention provides a portable infrared induction badminton block that is convenient to move.

The technical scheme that the present invention overcomes its technical problem adopts is:

The portable infrared sensor badminton block includes chassis Ⅰ and chassis Ⅱ, sliding sleeve Ⅰ and sliding sleeve Ⅱ vertically fixed on chassis Ⅰ and chassis Ⅱ, sliding locking device slidingly fixed in sliding sleeve Ⅰ and sliding sleeve Ⅱ Slider I and slider II, the upper end of the slider I is equipped with a prism, the infrared emitter is installed inside the slider I and directly behind the prism, and the upper end of the slider II is installed at a height corresponding to the prism There is a condenser lens, and an infrared receiver is installed inside the slide bar II and directly behind the condenser lens. The infrared light emitted by the infrared emitter is diverged by a prism to form an infrared light curtain. The height of the infrared light curtain is the same as The standard badminton blocks have the same height, and a buzzer is installed on the slide bar II, and the buzzer is electrically connected to the infrared receiver.

In order to adjust the height conveniently, the above-mentioned sliding locking device includes a number of sockets I and II which are respectively arranged on the slide bar I and the slide bar II from top to bottom and are equidistant from each other, and are respectively arranged on the sliding sleeve I and the sliding sleeve. The guide hole I and guide hole II on II, the pin shaft I inserted in the guide hole I and the socket I, and the pin shaft II inserted in the guide hole II and the socket II, the pin shaft I and the pin The outer ends of the shaft II are respectively fixed with the handle I and the handle II, the spring I is set on the pin shaft I and its two ends are respectively fixed on the handle I and the sliding sleeve I, the spring II is set on the pin shaft II and its two ends are respectively It is fixed on the pull handle II and sliding sleeve II.

In order to mark the highest position of the block, a condensing bowl is installed on the above-mentioned slider II and directly above the condensing lens, and a light bulb is installed in the condensing bowl.

The beneficial effect of the invention is that: the infrared rays emitted by the infrared emitter pass through the prism and diverge to form an infrared plane, forming a badminton block composed of an infrared light curtain. The red mesh light curtain focuses the light to the infrared receiver after passing through the condenser lens. If a ball touches the infrared plane, the infrared rays will be blocked, and the infrared receiver will drive a buzzer to give an alarm. The sliding rod I and the sliding rod II can slide up and down on the sliding sleeve I and the sliding sleeve II and are locked by the locking device, which is convenient for the user to freely adjust the height of the block. The portable infrared sensor badminton block is simple and easy to carry, overcomes the shortcomings of the existing badminton block which is clumsy and difficult to move, uses infrared detection technology to judge whether the ball has passed the net, and enhances the fairness of leisure sports.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing 1.

This portable infrared sensor badminton block includes chassis Ⅰ 1 and chassis Ⅱ 2, sliding sleeve Ⅰ 3 and sliding sleeve Ⅱ 4 vertically fixed on chassis Ⅰ 1 and chassis Ⅱ 2, sliding locking device slidingly fixed on sliding sleeve Ⅰ 3 and the slide bar I 13 and the slide bar II 14 in the sliding sleeve II 4, the upper end of the slide bar I 13 is equipped with a prism 16, and an infrared emitter 15 is installed in the slide bar I 13 and directly behind the prism 16, and the slide bar II A condenser lens 17 is installed at the height position corresponding to the prism 16 on the upper end of 14, and an infrared receiver 18 is installed inside the slide bar II 14 and positioned directly behind the condenser lens 17, and the infrared light emitted by the infrared emitter 15 diverges through the prism 16 to form An infrared light curtain, the height of the infrared light curtain is the same as the height of the standard badminton block, and the buzzer 19 is installed on the slide bar II 14, and the buzzer 19 is electrically connected to the infrared receiver 18. When in use, put the chassis Ⅰ 1 and chassis Ⅱ 2 on the field, and make the prism 16 and the condenser lens 17 face each other. The infrared ray emitter 15 emits infrared rays that pass through the prism 17 and diverges to form an infrared ray plane, forming an infrared light curtain. badminton block. The light curtain of the red network line focuses the light to the infrared receiver 18 after passing through the condenser lens 17 . If a ball touches the infrared plane, the infrared rays will be blocked, and the infrared receiver 18 drives the buzzer 19 to report to the police. The sliding rod I 13 and the sliding rod II 14 can slide up and down on the sliding sleeve I 3 and the sliding sleeve II 4 and are locked by the locking device, which is convenient for the user to freely adjust the height of the block. The portable infrared sensor badminton block is simple and easy to carry, overcomes the shortcomings of the existing badminton block which is clumsy and difficult to move, uses infrared detection technology to judge whether the ball has passed the net, and enhances the fairness of leisure sports.

The above-mentioned sliding locking device includes a plurality of jacks I 5 and II 6 that are respectively arranged on the slide bar I 13 and the slide bar II 14 from top to bottom and are equidistant from each other, and are respectively arranged on the sliding sleeve I 3 and the sliding sleeve Guide hole Ⅰ and guide hole Ⅱ on Ⅱ 4, pin shaft Ⅰ 11 inserted in guide hole Ⅰ and socket Ⅰ 5, and pin shaft Ⅱ 12 inserted in guide hole Ⅱ and socket Ⅱ 6, the pin shaft The outer ends of Ⅰ 11 and pin shaft Ⅱ 12 are respectively fixed with handle Ⅰ 7 and handle Ⅱ 8, spring Ⅰ 9 is set on the pin shaft Ⅰ 11 and its two ends are respectively fixed on handle Ⅰ 7 and sliding sleeve Ⅰ 3, spring Ⅱ 10 is set on the pin shaft II 12 and its two ends are respectively fixed on the handle II 8 and the sliding sleeve II 4. By pulling handle Ⅰ 7 and handle Ⅱ 8 to compress spring Ⅰ 9 and spring Ⅱ 10, pin shaft Ⅰ 11 and pin shaft Ⅱ 12 are pulled out from jack Ⅰ 5 and jack Ⅱ 6, and then slide bar Ⅰ 13 and After adjusting the height of the slider Ⅱ 14, loosen the handle Ⅰ 7 and the handle Ⅱ 8, under the elastic force of the spring Ⅰ 9 and the spring Ⅱ 10, the pin shaft Ⅰ 11 and the pin shaft Ⅱ 12 will be inserted into the corresponding socket again Ⅰ 5 and socket Ⅱ 6, the height of the slider Ⅰ 13 and the slider Ⅱ 14 can be locked, and the adjustment is simple and convenient.

Because infrared ray is invisible light, therefore people can't understand the height position of ball net when playing ball, so on the slide bar II 14 and be positioned at just above condenser lens 17, spotlight bowl 21 can be installed, and bulb 20 is installed in the spotlight bowl 21 . Bulb 20 emits light and forms a bundle of beams of light to irradiate the upper end of slide bar I 13 after the spotlight bowl 21 gathers light, can play the effect that makes things convenient for people to know the height of the ball net.
