Description

The sit-ups leg press

Technical field

The utility model is a kind of new device that is used for the body-building plastomer, belongs to sports equipment technical research field.

Background technology

Along with the continuous development competition of society is more and more fierce, it is nervous and heavy that people's work also is tending towards, but health is the capital of revolution, and good physique study and work is better arranged.People have designed various sports equipments to satisfy the needs of taking exercises, such as treadmill, barbell, weight bench, upside down machine etc. for this reason.

Concerning the overwhelming majority's university students and middle school students, they also do not have to set up the family of oneself but live in a dormitory, and there is not a fixing income, have a relatively large body-building apparatus and exist and be in want of funds and the limited problem in space, so present university students and middle school students becomes maximum selections in study or scientific research in ball game.In addition, students also can be selected some other fairly simple exercising way easily, such as sit-ups, almost each university students and middle school students did sit-up movement on the bed of oneself, particularly do the sit-ups of some evening before the sleep, not only convenient but also reached the purpose of taking exercise, a lot of people have such experience.

Summary of the invention

On bedroom bed, do the limited problem of sit-up movement in order to solve the student, allow numerous students that a good health can be arranged, designed a kind of new sports equipment---sit-ups leg press.Simple in structure, the dependable performance of this sit-ups leg press can satisfy the demand that the student does sit-up movement in bed, thereby reaches the purpose of taking exercises.

The utility model is that the technical scheme that problem adopted that solution proposes is: the sit-ups leg press is made up of base, pressure ring, cotton-padded covering, cotton pad, bearing pin, connecting rod, fixture etc.Its principal character is: pressure ring one end is connected on the base by straight pin, and the other end links to each other with base by bearing pin; One end of connecting rod is connected with base, and the other end is connected with fixture.Described fixture is made of interior fixed block, outer fixed block, bolt.

The beneficial effects of the utility model are to have satisfied the requirement that the student does sit-ups in bed, and structure is light and handy, and is with low cost, and most students can both afford, and easy to use, can not cause any damage to the bed body.So almost each student can realize taking exercise by sit-up movement in bed the hope of the health of oneself, trains a strong physique, drops into study and work better.
