Description

Technical Field

[0001] This utility model relates to the field of dance training, specifically an auxiliary leg-pressing device for dance training. Background Technology

[0002] After dance training, the leg muscles and ligaments are often in a state of tension and contraction. At this time, a four-level leg massager can be used to help relieve muscle tension, thereby improving leg flexibility and effectively reducing muscle soreness and discomfort caused by training.

[0003] Currently, when trainees use leg-pressing equipment, they usually place their lower legs on the rollers and then keep their lower legs straight while rolling on the rollers. However, since trainees' legs are quite tired after training, keeping their lower legs straight for a long time will cause even more fatigue, making leg pressing inconvenient. In addition, if a person slips during training, there may be a safety hazard. Therefore, in order to address the above problems, an auxiliary leg-pressing device for dance training is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technology and avoid the problem of leg pressing difficulties caused by operator fatigue, this utility model proposes an auxiliary leg pressing device for dance training.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an auxiliary leg pressing device for dance training, including a fixed plate, with handles fixedly connected to both the left and right sides of the fixed plate, and fixed rods fixedly connected to both the left and right sides of the front end of the fixed plate, with rollers rotatably connected to the surface of the fixed rods, and a support component provided in the middle of the front end of the fixed plate, with a blocking component provided on the surface of the support component.

[0006] The support assembly includes a vertical groove formed in the middle of the front end of a fixed plate. A threaded rod is rotatably connected inside the vertical groove. An internal threaded block is threadedly connected to the surface of the threaded rod. A support plate is fixedly connected to the front end of the internal threaded block. A fixed sleeve is fixedly connected to the center of the bottom end of the support plate. A winding rod is rotatably connected inside the fixed sleeve. A threaded insert rod is threadedly connected inside the fixed sleeve. Extension plates are slidably connected to both the left and right sides inside the support plate. A bottom rod is fixedly connected to the side of the bottom end of the extension plate near the middle of the support plate. A pull rope is wound around the surface of the winding rod. Protrusions are fixedly connected to both the left and right sides of the bottom end of the support plate. A fixing ring is fixedly connected to the end of the protrusion near the middle of the support plate.

[0007] Preferably, the threaded rod extends through the bottom end of the vertical groove to the outside of the fixed plate, and the internal threaded block is slidably connected inside the vertical groove. The operator can rotate the threaded rod located outside the fixed plate, thereby driving the internal threaded block to move up and down inside the vertical groove.

[0008] Preferably, the winding rod has an annular groove inside that is adapted to engage with the threaded insert rod. The end of the pull rope away from the winding rod passes through the fixing ring and is fixedly connected to the surface of the base rod. Rotating the threaded insert rod causes it to engage inside the annular groove, thus preventing the winding rod from rotating further. Rotating the winding rod, however, can wind the pull rope to pull the base rod, causing the base rod to move the extension plate outward toward the support plate.

[0009] Preferably, the blocking assembly includes two notches on the left and right sides of the extension plate, with baffles rotatably connected inside the notches, and torsion springs fixedly connected to both ends of the baffles. Sliding grooves are provided on both the front and rear sides of the left and right ends of the extension plate, with sliding plates slidably connected inside the sliding grooves, and a pressure spring fixedly connected to the end of the sliding plate away from the baffle.

[0010] Preferably, the end of the torsion spring away from the baffle is fixedly connected to the inner wall of the notch, and the end of the pressure spring away from the sliding plate is fixedly connected to the inner wall of the groove.

[0011] Preferably, the groove and the notch are connected, and the bottom end of the sliding plate and the top end of the baffle are adapted to contact each other. When the baffle is rotated to a horizontal state, the sliding plate moves above the baffle under the action of the pressure spring, thereby keeping the baffle in a horizontal state.

[0012] The advantages of this utility model are:

[0013] This invention allows trainees to adjust the vertical position of the support plate according to their height when they need to stretch their legs. This ensures that the lower legs are placed straight on top of the roller and support plate, allowing the lower legs to roll on the surface of the roller to complete the leg stretching exercise. Simultaneously, the baffle on the other side of the lower legs can be rotated to a vertical position, preventing the lower legs from slipping off the top of the support plate and thus preventing the trainee from slipping and falling during the leg stretching exercise, thereby ensuring the safety of the trainee.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1 — Figure 5 This application will be described in further detail.

[0023] This application discloses an auxiliary leg-pressing device for dance training. (Refer to...) Figure 1 A dance training auxiliary leg pressing device includes a fixed plate 1, with grips 2 fixedly connected to both the left and right sides of the fixed plate 1, and fixed rods 31 fixedly connected to both the left and right sides of the front end of the fixed plate 1. Rollers 32 are rotatably connected to the surface of the fixed rods 31, and a support component 4 is provided in the middle of the front end of the fixed plate 1. A blocking component 5 is provided on the surface of the support component 4.

[0024] Reference Figure 2 - Figure 4The support assembly 4 includes a vertical groove 41 located in the middle of the front end of the fixed plate 1. A threaded rod 42 is rotatably connected inside the vertical groove 41. An internal threaded block 43 is threadedly connected to the surface of the threaded rod 42. The threaded rod 42 extends through the bottom end of the vertical groove 41 to the outside of the fixed plate 1. The internal threaded block 43 is slidably connected inside the vertical groove 41. The operator can rotate the threaded rod 42 located outside the fixed plate 1, thereby driving the internal threaded block 43 to move up and down inside the vertical groove 41. A support plate 44 is fixedly connected to the front end of the internal threaded block 43. A fixed sleeve 451 is fixedly connected to the center of the bottom end of the support plate 44. A winding rod 452 is rotatably connected inside the fixed sleeve 451. A threaded insertion rod 453 is threadedly connected inside the fixed sleeve 451. Extension plates 4 are slidably connected to both the left and right sides inside the support plate 44. 6. A bottom rod 47 is fixedly connected to the bottom end of the extension plate 46 near the middle of the support plate 44. A pull rope 48 is wound around the surface of the winding rod 452. Protrusions 491 are fixedly connected to both the left and right sides of the bottom end of the support plate 44. A fixing ring 492 is fixedly connected to the end of the protrusion 491 near the middle of the support plate 44. An annular groove adapted to engage with the threaded rod 453 is opened inside the winding rod 452. The end of the pull rope 48 away from the winding rod 452 passes through the fixing ring 492 and is fixedly connected to the surface of the bottom rod 47. Rotating the threaded rod 453 causes it to engage inside the annular groove, thus preventing the winding rod 452 from rotating further. Rotating the winding rod 452 can wind the pull rope 48, thereby pulling the bottom rod 47, causing the bottom rod 47 to drive the extension plate 46 to move outward of the support plate 44.

[0025] Reference Figure 3 and Figure 5 The blocking component 5 includes two notches 51 on the left and right sides of the extension plate 46. A baffle 52 is rotatably connected inside the notch 51. A torsion spring 53 is fixedly connected to both the front and rear ends of the baffle 52. A sliding groove 54 is provided on both the front and rear sides of the left and right ends of the extension plate 46. A sliding plate 55 is slidably connected inside the sliding groove 54. A pressure spring 56 is fixedly connected to the end of the sliding plate 55 away from the baffle 52. The end of the torsion spring 53 away from the baffle 52 is fixedly connected to the inner wall of the notch 51. The end of the pressure spring 56 away from the sliding plate 55 is fixedly connected to the inner wall of the sliding groove 54. The sliding groove 54 and the notch 51 are connected. The bottom end of the sliding plate 55 and the top end of the baffle 52 are adapted to contact each other. When the baffle 52 is rotated to a horizontal state, the sliding plate 55 moves above the baffle 52 under the action of the rebound force of the pressure spring 56, thereby keeping the baffle 52 in a horizontal state.

[0026] Working principle: When the trainee needs to press their legs, first rotate the threaded rod 42 to drive the threaded internal thread block 43 to move vertically inside the vertical groove 41. At this time, the internal thread block 43 will drive the support plate 44 to move accordingly until the support plate 44 is adjusted to a suitable position. Then rotate the threaded insert rod 453 to disengage it from the annular groove of the winding rod 452. Then rotate the winding rod 452 to wind the pull rope 48. At this time, the pull rope 48 is pulled and drives the bottom rod 47 to move out of the support plate 44. At this time, the bottom rod 47 will drive the fixedly connected extension plate 46 to move out of the support plate 44. When the extension plate 46 is pulled out of the support plate 44, rotate the threaded insert rod 453 to lock it inside the annular groove. At this time, the winding rod 452 is restricted and cannot continue to rotate, that is, the position of the extension plate 46 is restricted.

[0027] At this time, the sliding plate 55 abuts against the top of the baffle 52 under the elastic force of the pressure spring 56. Therefore, the baffle 52 remains horizontal and the torsion spring 53 is compressed. Then, push the sliding plate 55 on the other side of the support plate 44 away from the personnel. The sliding plate 55 will compress the pressure spring 56 and slide inside the slide groove 54 until the sliding plate 55 slides away from the baffle 52. At this time, the baffle 52 will rotate to a vertical position under the rebound force of the torsion spring 53. Then release the sliding plate 55. The sliding plate 55 will abut against the side wall of the baffle 52 under the rebound force of the pressure spring 56. At this time, the baffle 52 remains vertical under the elastic force of the torsion spring 53 and the pressure of the sliding plate 55. The adjustment of the baffle 52 is now complete.

[0028] The trainee then places their lower leg on top of the roller 32 and their foot on top of the support plate 44. At this time, the trainee holds the handle bar 2 and slides their lower leg on the surface of the roller 32 to perform leg press. During the leg press, the foot slides on top of the support plate 44 and the extension plate 46, and the baffle 52 blocks the foot to prevent it from leaving the support plate 44 and the extension plate 46, thereby preventing the trainee from slipping and completing the leg press.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
