Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, and in particular to a dance practice stand for dance teaching. Background Technology

[0002] With the development of society, people attach great importance to fitness activities. As a result, fitness equipment is constantly being optimized to make people's movements more standardized and to protect fitness enthusiasts from injury. The use of fitness equipment has greatly simplified the fitness learning process and improved the efficiency of fitness.

[0003] Currently, people use dance practice frames for dance fitness. However, existing dance fitness frames cannot limit the movement of some beginners when stretching their legs. This can lead to some beginners straining their calves due to excessive force, thus affecting the fitness effect.

[0004] Based on this, the present invention designs a dance practice frame for dance teaching to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a dance practice stand for dance teaching, which aims to solve the technical problems existing in the prior art mentioned in the background section.

[0006] The present invention is implemented as follows: a dance practice frame for dance teaching, the practice frame comprising: Dance stand: It is equipped with a mounting platform, and the surface of the mounting platform is fixedly installed with an anti-slip mat; Limiting mechanism: includes a limiting airbag installed on the mounting platform to limit the lower leg and multiple massage balls. The limiting airbag is connected to an external air pump through a hose. The limiting airbag is fixedly installed on a rotating semi-cylinder, and the rotating semi-cylinder is rotatably connected to the fixed semi-cylinder. Reciprocating mechanism: In coordination with an eccentric mechanism, it drives multiple massage balls to reciprocate. Centrifugal mechanism: Reduces the oscillation speed of the sliding mechanism by cooperating with the eccentric mechanism.

[0007] Furthermore, the reciprocating mechanism includes a cross bar fixedly connected to the massage ball. The cross bar passes through the fixed semi-cylinder and is slidably connected to the fixed semi-cylinder. The cross bar is connected to the surface of the fixed semi-cylinder through a reciprocating spring. Multiple cross bars are fixedly mounted on a connecting plate. The connecting plate is fixedly mounted on a right-angle block. The right-angle block is slidably connected to the sliding mechanism. The surface of the right-angle block is rotatably connected to the swing rod. The end of the swing rod away from the right-angle block is rotatably mounted on a movable slide plate that cooperates with the eccentric mechanism. The movable slide plate is slidably connected to the sliding mechanism.

[0008] Furthermore, the eccentric mechanism includes an eccentric wheel rotatably mounted on the sliding mechanism and cooperating with the movable slide plate. A rotating gear is fixedly mounted on the surface of the eccentric wheel, and the rotating gear meshes with an arc-shaped rack, which is fixedly mounted on the sliding mechanism.

[0009] Furthermore, the centrifugal mechanism includes a centrifugal wheel fixedly mounted on a rotating gear, with multiple centrifugal blocks slidably mounted on the inner wall of the centrifugal wheel. Each centrifugal block is connected to the inner wall of the centrifugal wheel via a centrifugal spring. It also includes an arc-shaped rubber strip fixedly mounted on a sliding mechanism to cooperate with the centrifugal blocks.

[0010] Furthermore, the sliding mechanism includes a sliding plate fixedly connected to the fixed semi-cylinder, a connecting column fixedly connected to the surface of the sliding plate, the connecting column fixedly installed on the arc-shaped slider, the arc-shaped slider slidably connected to the arc-shaped track plate, and the surface of the arc-shaped track plate fixedly connected to the mounting platform and the handrail.

[0011] Furthermore, the surface of the mounting platform is fixedly equipped with an anti-slip pad.

[0012] Furthermore, a rubber block is provided at the contact end between the centrifugal block and the arc-shaped rubber strip.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention involves a beginner lifting and stretching their legs, causing a fixed semi-cylinder and a rotating semi-cylinder to slide on a sliding mechanism. During the sliding process, the reciprocating mechanism and the eccentric mechanism drive multiple massage balls to reciprocate, thereby massaging the beginner's calves and relaxing the calf muscles, thus preventing muscle strain during the stretching process.

[0014] 2. This invention uses a centrifugal mechanism to quickly limit the movement of the fixed and rotating semi-cylinders, thus avoiding leg strains for beginners. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 10 As shown, in one embodiment, a dance practice frame for dance teaching is provided, the practice frame comprising: Dance stand 1: It is equipped with a mounting platform 101, and an anti-slip mat 102 is fixedly installed on the surface of the mounting platform 101; Limiting mechanism 2: includes a limiting airbag 201 installed on the mounting platform 101 to limit the lower leg and multiple massage balls 202. The limiting airbag 201 is connected to an external air pump through a hose. The limiting airbag 201 is fixedly installed on a rotating semi-cylinder 204. The rotating semi-cylinder 204 is rotatably connected to the fixed semi-cylinder 203. Reciprocating mechanism 3: In cooperation with eccentric mechanism 4, it drives multiple massage balls 202 to reciprocate. Centrifugal mechanism 5: Reduces the oscillation speed of sliding mechanism 6 by cooperating with eccentric mechanism 4.

[0020] In practical applications, when beginners perform dance stretching movements, such as... Figure 1 and Figure 10 As shown, first rotate the rotating semi-cylinder 204 to open it. Then, bring the lower leg close to the fixed semi-cylinder 203. Next, rotate the rotating semi-cylinder 204 to close it, so that the rotating semi-cylinder 204 and the fixed semi-cylinder 203 form a complete cylinder, thus covering the beginner's lower leg. Figure 6 As shown, air is injected into the limiting airbag 201 via an external air pump, wrapping the lower leg between the limiting airbag 201 and multiple massage balls 202, thereby achieving automatic fixation of the lower leg. At this point, the beginner begins to lift and stretch the leg, causing the fixed semi-cylinder 203 and the rotating semi-cylinder 204 to slide on the sliding mechanism 6, as shown. Figure 3 , Figure 5 and Figure 8 As shown, during the sliding process, the reciprocating mechanism 3 and the eccentric mechanism 4 drive multiple massage balls 202 to reciprocate, thereby massaging the beginner's calves and relaxing the calf muscles. This prevents muscle strain during stretching and also helps to prevent injury if the leg is lifted too quickly during the stretching process. Figure 10 As shown, the centrifugal mechanism 5 quickly limits the fixed semi-cylinder 203 and the rotating semi-cylinder 204, avoiding leg strain for beginners. At the same time, the symmetrical design makes it easier for beginners to switch leg training, improving the flexibility of the device.

[0021] like Figure 7 and Figure 8As shown, in a preferred embodiment of the present invention, the reciprocating mechanism 3 includes a cross bar 301 fixedly connected to the massage ball 202. The cross bar 301 passes through the fixed semi-cylinder 203 and is slidably connected to the fixed semi-cylinder 203. The cross bar 301 is connected to the surface of the fixed semi-cylinder 203 through a reciprocating spring 302. Multiple cross bars 301 are fixedly installed on a connecting plate 303. The connecting plate 303 is fixedly installed on a right-angle block 304. The right-angle block 304 is slidably connected to the sliding mechanism 6. The surface of the right-angle block 304 is rotatably connected to the swing rod 305. The end of the swing rod 305 away from the right-angle block 304 is rotatably installed on a movable slide plate 306 that cooperates with the eccentric mechanism 4. The movable slide plate 306 is slidably connected to the sliding mechanism 6.

[0022] In practical applications, when beginners perform leg-raising and leg-retracting movements, such as... Figure 8 As shown, the eccentric mechanism 4 drives the movable slide plate 306 to reciprocate vertically. The movement of the movable slide plate 306 drives the cross rod 301 to reciprocate horizontally through the swing rod 305, the right-angle block 304 and the connecting plate 303, which in turn drives the massage ball 202 to reciprocate horizontally, thereby achieving the purpose of automatically massaging the leg muscles.

[0023] like Figure 4 , Figure 5 and Figure 10 As shown, in another preferred embodiment of the present invention, the eccentric mechanism 4 includes an eccentric wheel 401 rotatably mounted on the sliding mechanism 6 and cooperating with the movable slide plate 306. A rotating gear 402 is fixedly mounted on the surface of the eccentric wheel 401. The rotating gear 402 meshes with an arc-shaped rack 403, which is fixedly mounted on the sliding mechanism 6.

[0024] In practical applications, when beginners perform leg-raising and leg-retracting movements, such as... Figure 10 As shown, the rotating gear 402 is driven to rotate by the interaction of the arc-shaped rack 403 with the rotating gear 402, as... Figure 5 As shown, the rotation of the rotating gear 402 drives the eccentric wheel 401 to rotate, and then through the cooperation between the eccentric wheel 401 and the movable slide plate 306, the movable slide plate 306 is driven to perform vertical reciprocating motion, thereby driving the massage ball 202 to massage the legs through the reciprocating mechanism 3.

[0025] like Figure 10As shown, in another preferred embodiment of the present invention, the centrifugal mechanism 5 includes a centrifugal wheel 501 fixedly mounted on a rotating gear 402, a plurality of centrifugal blocks 502 slidably mounted on the inner wall of the centrifugal wheel 501, each centrifugal block 502 being connected to the inner wall of the centrifugal wheel 501 by a centrifugal spring 503, and also includes an arc-shaped rubber strip 504 fixedly mounted on a sliding mechanism 6 to cooperate with the centrifugal blocks 502.

[0026] In practical applications, when beginners perform rapid leg raises and retractions, as in the embodiments of this invention... Figure 10 As shown, at this time, the rotating gear 402 rotates rapidly, which in turn drives the centrifugal wheel 501 to rotate rapidly. The rapid rotation of the centrifugal wheel 501 drives the centrifugal block 502 away from the central axis of the centrifugal wheel 501 through the action of centrifugal force. At this time, the centrifugal wheel 501 extends and contacts the arc-shaped rubber strip 504, thereby quickly reducing the movement speed of the fixed semi-cylinder 203 and the rotating semi-cylinder 204 through the frictional resistance of the contact, thus avoiding strain on the legs.

[0027] like Figure 6 As shown, in another preferred embodiment of the present invention, the sliding mechanism 6 includes a sliding plate 601 fixedly connected to the fixed semi-cylinder 203, a connecting post 602 fixedly connected to the surface of the sliding plate 601, the connecting post 602 being fixedly mounted on the arc-shaped slider 603, the arc-shaped slider 603 being slidably connected to the arc-shaped track plate 604, and the surface of the arc-shaped track plate 604 being fixedly connected to the mounting platform 101 and the handrail 103.

[0028] In practical applications, when beginners are stretching their legs, as in the embodiments of this invention... Figure 6 As shown, the leg muscles drive the fixed semi-cylinder 203 and the rotating semi-cylinder 204 to move in an arc, which in turn drives the arc-shaped slider 603 to slide in the arc-shaped track plate 604, thereby performing an ergonomic leg stretching action.

[0029] like Figure 1 As shown, in another preferred embodiment of the present invention, an anti-slip pad 102 is fixedly installed on the surface of the mounting platform 101.

[0030] In practical applications, the embodiments of the present invention, such as Figure 1 As shown, the anti-slip mat 102 prevents beginners from slipping and injuring their legs while practicing stretching.

[0031] like Figure 9 and Figure 10 As shown, in another preferred embodiment of the present invention, a rubber block is provided at the contact end between the centrifugal block 502 and the arc-shaped rubber strip 504.

[0032] In practical applications, the embodiments of the present invention, such as Figure 10 As shown, the rubber block at the contact end of the centrifugal block 502 and the arc-shaped rubber strip 504 increases the contact friction, thereby making the restricted movement more stable.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention.
