Description

Technical Field

[0001] The utility model relates to a fitness equipment, in particular to a waist and back exerciser. Background Art

[0002] Existing waist and back exercisers generally support a roller with a fixed height through a bracket. The exerciser moves up and down with his back to the roller, and exercises the waist and back through friction and pressure. Since the roller has a fixed height, it is not adaptable to people of different heights, and it is not convenient to change the exercise part. In addition, the exerciser needs to apply side force against the roller, and the pressure is small, so the exercise effect is not good. Summary of the invention

[0003] The utility model aims to provide a waist and back exerciser to solve the defect that the existing waist and back exercisers have poor use effects.

[0004] The purpose of the utility model is achieved in the following way: a waist and back exerciser, including a massage device, the massage device is a lifting massage device, the lifting massage device has a massage base, two telescopic columns with adjustable heights are fixed alternately on the massage base, support sleeves are fixed on the telescopic columns, opposite shaft sleeves are fixed on the inner sides of the two support sleeves, the two shaft sleeves support and fix roller shafts through inner holes, the roller shaft supports an axially positioned and rotatable roller, support rods are fixed on the front and rear sides of each support sleeve, and an armrest is fixedly supported between the two support rods on each support sleeve; a lifting support platform is arranged in front of or behind the lifting massage device.

[0005] The lifting support platform is a scissor-type lifting platform.

[0006] The lifting support platform has a support platform base, a horizontal support table top is arranged above the support platform base, connecting ears are arranged on the upper part of the support platform base and the lower part of the support table top at the front position near the inner and outer edges, and T-shaped slide rails along the length direction are arranged on the upper part of the support platform base and the lower part of the support table top at the rear position near the inner and outer edges, a slider is placed in the T-shaped slide rail, and two pairs of swing rods are arranged on the inner and outer sides in the space between the support platform base and the support table top, and a hinge shaft passes through the through hole in the middle of each swing rod to hinge the two pairs of swing rods together in an X shape, and the front ends of the inner and outer swing rods are correspondingly hinged at On the connecting ears of the support platform base and the support platform surface, the rear upper ends of the inner and outer swing rods are hinged to the slider in the T-shaped slide rail of the support platform surface, and the rear lower ends of the inner and outer swing rods are hinged to a push-pull rod. The two ends of the push-pull rod are hinged to the slider in the T-shaped slide rail of the support platform base. A nut is fixed to the middle of the push-pull rod, and a horizontal pull screw is also provided. The horizontal pull screw and the nut are connected by threads. A handwheel frame is fixed on the support platform base, and the horizontal pull screw is supported and axially positioned by the handwheel frame. A handwheel is fixed to the end of the horizontal pull screw. Sponge can be laid on the upper surface of the support platform surface, and leather is covered on the sponge to make it soft.

[0007] The telescopic column includes a sleeve with an internal threaded hole fixed to the massage base by bolts, and is further provided with a lifting screw. The lower part of the lifting screw is connected to the internal threaded hole of the sleeve, the upper end of the lifting screw is provided with a convex ring, and the upper part of the convex ring is provided with a square end head. The support sleeve is rotatably mounted on the lifting screw, and a lower locking nut and an upper locking nut are provided on the lifting screw between the upper end surface of the sleeve and the lower end surface of the support sleeve. The lower locking nut abuts against the upper end surface of the sleeve, the upper end surface of the support sleeve abuts against the bottom surface of the convex ring, and the upper locking nut abuts against the lower end surface of the support sleeve.

[0008] The lifting massage device and the lifting support platform are connected and fixed together through a connecting piece, and the connecting piece can be fixed between the massage base and the support platform base by bolts.

[0009] A plurality of ridges are arranged on the circumferential surface of the drum to enhance the pressing effect; a rubber sheet may also be laid on the outer circumference of the drum to increase elasticity and softness.

[0010] Before use, the height of the roller and the height of the lifting support platform can be adjusted according to the needs of the exerciser. Loosen the lower locking nut and the upper locking nut, use a tool to clamp the square end and rotate the lifting screw to make the lifting screw rise or fall relative to the sleeve, thereby raising or lowering the roller. After the roller position is adjusted, lock the lower locking nut and the upper locking nut, and the upper and lower positions and circumferential directions of the support sleeve are locked and positioned; turning the hand wheel can drive the horizontal pull screw to rotate, and the nut pulls the push-pull rod to move forward and backward, and the push-pull rod drives the X-shaped swing rod hinged together to increase or decrease the angle, and the support table rises or falls, so as to achieve the purpose of adjusting the height of the lifting support platform.

[0011] When exercising, adjust the height of the roller to the height of the hips, hold the handrails with both hands, lie flat on the roller, then hold the back of the head with both hands, start exercising from the middle position of the shoulders, use the force of the legs to move the shoulders back and forth on the roller several times, then move the left shoulder or right shoulder on the roller respectively, and bend the body downward in the direction of the roller's rotation, and exercise the middle and both sides of the waist in the same way. Finally, when exercising the coccyx, support the back with both hands to rotate the coccyx to the top of the roller. At this time, the weight of the body will be heavier on top and lighter on the bottom, with the feet facing up and the head facing down on the support surface. Use the coccyx to drive the legs to swing left and right, or cross the legs, or move up and down. The above movements will not cause compression between the vertebrae when the back of the body is bent downward, and have the dual effects of stretching and massage, which improves the exercise effect.

[0012] The roller height of the utility model can be adjusted, which is highly adaptable to people of different heights and convenient for changing the exercise part; the armrest and the lifting support platform cooperate to facilitate the change of the exercise part, assist in supporting and assisting in applying force, and have a safety protection function. The utility model is used for waist, back and shoulder exercise, and has a good exercise effect. BRIEF DESCRIPTION OF THE DRAWINGS
