Abstract

A hands-impellent circle for students in middle or elementary schools to play is composed of a hollow roller and a push rod. A filler opening located at inner side of the hollow roller is pressurized by a sealed cap. According to interests of users, liquid in different quantity can be injected to the hollow roller through the opening in order to change mass of the roller. The push rod consists of a handle and a U typed ring. The hole on the U typed ring for guarding against being pulled out is located near the part of the handle. The roller and the handle are connected by a string so as to form one unity. A concave ring able to be rolled is pulled-on the base so as to change sliding friction to rolling friction, and to reduce resistance when the roller is pushed. Compared with the existing technology: has the advantages of simple structure, low cost, through the injection liquid can change wheel quality, increase the activity of the difficulty and interest, is advantageous for the promotion, the use of safety; when not in use, can be connected together, convenient store, A sports teaching aid and a learning aid are fit for primary and middle school students' fitness and exercise.

Description

Students in middle and primary schools use body-building hand push circle

Technical field

The utility model relates to a kind of middle and primary schools physical culture teaching aid or toy, is that students in middle and primary schools use body-building hand push circle specifically.

Background technology

How to allow students in middle and primary schools have a passionate love for sports, have deep love for to take exercise, teaching aid plays a role, and existing physical culture teaching aid, particularly body-building apparatus mostly are and fix on the ground, movable, movably very little, traditional push away the iron hoop good physical training style of can yet be regarded as, and existing iron hoop quality is fixed, and lacks interesting consistent with difficulty, be unfavorable for student's self-challenge, also cannot allow the student do it yourself to operate.

The utility model content

The purpose of this utility model is the deficiency at above-mentioned sports equipment, provides a kind of students in middle and primary schools that can change quality to use body-building hand push circle.

The purpose of this utility model realizes by following technological means: students in middle and primary schools are made up of hollow roller and push rod with body-building hand push circle, and there is a liquid injection port hollow roller inboard, and liquid injection port seals with seal cover.Liquid injection port is mainly used in injects water or other liquid in the way roller, the liquid that can inject different amounts according to user's interest is to increase the quality of roller.

Described push rod is made up of handle and U type ring, and U type ring has anticreep to portal near the part of handle, can roller and handle be linked together with cord, makes the two become an integral body and does not separate; The bottom is with a spill ring that can roll, and the change sliding friction is rolling friction, reduces the resistance when pushing away roller.

Compared with prior art the utlity model has following tangible advantage: simple in structure, cheap, can change the quality of roller by the fluid injection body, the difficulty of the activity of increase and interest are convenient to promote, and be safe in utilization; The two can be connected together when not using, relatively deposit, be the physical culture teaching aid and the learning aid of a kind of suitable students in middle and primary schools' body-building and motion.

The specific embodiment

Below in conjunction with description of drawings the utility model is described in further detail:

These students in middle and primary schools with the use of body-building hand push circle are: during use, the liquid injection port 7 of hollow roller 5 is opened, according to user's interest, can not add liquid, also can inject certain amount of fluid or fill 6 sealings of usefulness seal cover, place on the ground, promote, can advance with U type ring 4; When not using, the liquid of hollow roller 5 inside is emitted, be placed in the U type ring 4, pass anticreep with cord and portal and 2 tie up on U type ring 4, so that the two does not separate.

In a word, the utility model provides students in middle and primary schools to use body-building hand push circle.The above; it only is a part of specific embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
