Background

Badminton is an indoor sports item of small balls which is made of feathers and cork and is hit by using a long-handle netted racket with a net interposed therebetween. In order to enable the abilities of students to be more evenly developed, badminton courses are added to many schools for the students to learn. In the teaching process of badminton courses, the badminton net rack is often used by related teaching personnel. The patent document with the prior art publication number of CN210096850U provides a badminton net rack for physical education, which uses several small nets to form a conventional badminton net, and better solves the problem of uneven net height caused by that the upper edge of the net sinks due to gravity after being used because the whole standard net is large and heavy, and if the small net at the top end has uneven net height, the small net at the bottom layer can be used for replacing the small net, thereby ensuring that the badminton net rack can be used for a long time. Although the device has more beneficial effects, the following problems still exist: because the gymnasium in the school of learning can be used for the teaching of different courses often, consequently, the relevant teaching personnel of badminton all need hang all nets before the badminton course at every turn and establish on the rack, need pull down the collection to the net again after the course ends. The workload of related teaching personnel is increased, the badminton curriculum time is possibly delayed, and the teaching effect is influenced. In view of this, we propose a badminton net rack for physical education.

Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a badminton rack for sports teaching, including two removal bases 1, remove 1 top surface middle part of base and be equipped with telescopic link 2, the purpose that sets up telescopic link 2 is convenient for highly adjust the net 16, 2 top surface middle parts of the telescopic link of one side are rotated and are connected with and hold post 12, it is equipped with dwang 3 to hold post 12 upside, both ends all are equipped with and accept dish 15 about

dwang

3, 3 circumference outer walls of dwang are convoluteed there is net 16, it is equipped with wind spring 6 to hold 12 circumference outer wall upside covers of post, the purpose that sets up wind spring 6 is convenient for carry out the rolling to the net 16 that expandes, 6 outer ends of wind spring are connected with fixed plate 4, 2 top surface T shape dead levers 5 of telescopic link of opposite side.

Specifically, the right end of the ball net 16 is fixedly connected with the left side of the circumferential outer wall of the T-shaped fixing rod 5, and the upper end of the receiving column 12 is fixedly connected with the bottom surface of the receiving tray 15 on the lower side.

Furthermore, the bottom surface of the fixed plate 4 is fixedly connected with the top surface of the corresponding telescopic rod 2, and the inner end of the coil spring 6 is fixedly connected with the circumferential outer wall of the bearing column 12.

Still further, the ratchet 7 is connected to the circumference outer wall downside of accepting

post

12, 2 circumference outer wall left part upsides of the telescopic link of one side are equipped with L shape loading board 14, L shape loading board 14 upper end is connected with fixed cover 10, fixed cover 10 inner wall sliding connection has sliding plate 9, the sliding plate 9 right-hand member is connected with triangle-shaped spacing tooth 8, the purpose of setting up ratchet 7 and triangle-shaped spacing tooth 8 is convenient for carry on spacingly to net 16, prevent that net 16 from moving in the use, triangle-shaped spacing tooth 8 outer wall and ratchet 7 outer wall swing joint.
