Description

A kind of Time-marking device

Technical field

The utility model relates to a kind of sports apparatus, relates in particular to a kind of Time-marking device.

Background technology

Quickening along with modern's rhythm of life makes most of people for sub-health state.More people begins the importance paying attention to moving, and various sports apparatus arise at the historic moment.The motion of marking time of Time-marking device is a kind of sports products that lower part of the body aerobic exercise and muscular movement are carried out simultaneously, and it is easy to use, and occupation of land is few, obtains doting on of increasing people.Pedal that can move up and down and oil compression rod that the Time-marking device utilization is fixed on the support are alternately down stepped on about the original place is continuous by turns, thereby simulation is run or the motion of footrace.Present pedal device product is a lot, and the Time-marking device shown in Fig. 1 is interior is present the most frequently used on the market a kind of Time-marking device.Time-marking device comprises base 1, connects by connecting rod 2 in the middle of the base of front and back.Be provided with vertical stand steel pipe 3 at preceding base 1 mid portion, base 1 is provided with pedal 4, and pedal drives control by oil compression rod, and oil compression rod comprises that the free kinematic axis 5a that twitches up and down forms with the oil pressure cylinder 5b that is connected kinematic axis.When the Time-marking device that forms according to said structure moved, the user at first was placed on two pin on the pedal of the left and right sides, this be pedal because the body weight center of gravity toward the principle that presses down, kinematic axis 5a motion in the oil pressure cylinder 5b.The user alternately steps on plate, and the gravity center of human body alternately, does not have the kinematic axis of pedal oil compression rod of center of gravity protruding on two pedals.Action so continuously, the tail end of pedal be the bump base constantly, and impulsive force can be communicated to user's health by pedal, all has certain impact for joint, cervical vertebra and brain, also damages apparatus simultaneously easily.

Summary of the invention

The utility model mainly provides a kind of good buffer effect; can effectively protect the user not involved by shock wave; Time-marking device simple in structure, the pedal tail end and the base that solve the existing in prior technology Time-marking device constantly clash into the technical problem that causes human body to be hurt.

The utility model provides a kind of long service life simultaneously, and noise is little, the non-damageable Time-marking device of accessory; Solve the Time-marking device that exists in the prior art and damage the technical problem that noise is big easily.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of Time-marking device, comprise support, respectively be provided with a pedal in described support both sides, base and rear base before below described pedal, being provided with, base links to each other by connecting rod with rear base before described, the bottom surface of described pedal is fixed with telescopic shaft, described telescopic shaft moves in retracting cylinder, described retracting cylinder is fixed on the preceding base, the rear end of described pedal contacts with described rear base, is provided with buffer unit in described contact position.Because moving up and down of pedal needs to rely on rear base to play the effect of support, also plays spacing effect simultaneously.Pedal moves upward with regard to return after moving downward and striking rear support, and the position of the easiest generation bump of treadmills is exactly pedal rear end and rear base position contacting.In both contact positions buffer unit is set, can prevent effectively that the shock wave that the user produces from damaging human body when pushes pedals strikes rear base, simultaneously, owing to be provided with buffer unit, can effectively reduce the degree of wear of rear base and pedal, improve the service life of accessory, the noise that produces in the time of also can reducing rear base and pedal bump.

As preferably, described buffer unit is a spring steel plate, and described spring steel plate comprises stiff end and force side, is provided with the transition brace between described stiff end and the force side.Spring steel plate has certain elasticity, and when pedal contacted with rear base, the force side touched earlier, alleviates both impacts by the transition of transition brace.Spring steel plate is installed simple and direct, simple in structure.

As more preferably, described spring steel plate is stepped, and described transition brace is obliquely installed, and the angle of described transition brace and force side is the obtuse angle.Stair-stepping spring steel plate, the impulsive force in the time of can better absorbing pedal and move up and down, the angle of force side and transition brace is the obtuse angle, reduces stress and concentrates, and impulsive force can be scattered, and makes the longer service life of spring steel plate, elastic force is better simultaneously.

Preferred as another kind, described buffer unit is a coil component spring, and an end of coil component spring is a stiff end, and the other end is the force side.The buffer unit of coil component spring is simple in structure, and elastic force is better, and well shock-absorbing cushions, and can increase the restoring force of pedal.

As preferably, be fixed with cushion pad on the working face of the force side of buffer unit.Cushion pad the raising buffering effect is set, reduce the wear intensity of buffer unit, and can play the effect of absorption noise simultaneously.

As more preferably, described cushion pad is made of synthetic resin or elastomeric material.Adopt synthetic resin and elastomeric material to make cushion pad, make that the good springiness of cushion pad is durable.

As a kind of preferred, described buffer unit is fixed on the bottom surface of the tail end of pedal.Buffer unit is installed concealed, makes that the treadmills profile is more neat and artistic.

Preferred as another kind, described buffer unit is fixed on the described rear base.Easy installation and removal, support effect is good.

As preferably, described rear base is cylindric, and the end face that contacts with described pedal at described rear base is an arc surface.Circular-arc end face can reduce impulsive force when buffer unit touches rear base, play cushioning effect, reduces the wearing and tearing of buffer unit.

As preferably, described pedal is provided with skid resistant course.Can allow the user safer when taking exercise, train on is good.

Therefore, Time-marking device of the present utility model has following advantage: 1. between pedal and rear base buffer unit is set, can effectively prevents the impulsive force when pedal falls, reduce the influence of impulsive force to the person; 2. buffer unit adopts elastic steel sheet or coil component spring, and is simple in structure, good buffer effect; 3. buffer unit is provided with cushion pad, can reduce noise, can reduce the wearing and tearing of accessory simultaneously, improves the service life of accessory; 4. skid resistant course is installed, the security when the raising user takes exercise on pedal.
