Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sports training, specifically to a novel dance leg pressing device for sports training. BACKGROUND

[0002] In the field of sports training, especially dance training, leg pressing is a basic and crucial training link, which plays a key role in improving the flexibility, body coordination and dance action quality of dancers.

[0003] At present, the common dance leg pressing devices on the market have many defects. The traditional leg pressing rod is mostly fixed in structure, and the height and angle cannot be flexibly adjusted. For dancers of different heights and different training stages, personalized adjustment cannot be made according to actual needs, which greatly limits the training effect and may lead to discomfort or even injury risk during training.

[0004] Part of the adjustable leg pressing device has a complex and tedious adjustment mode, which is inconvenient to operate. Dancers need to spend a lot of time and effort to adjust during training, which seriously affects the training efficiency and cannot meet the demand of quickly switching training state. Moreover, the adjustment structure of these devices has poor stability, and is prone to looseness, displacement and other situations during use, affecting the safety and continuity of training. UTILITY MODEL CONTENT

[0005] In view of the deficiencies in the prior art, the utility model provides a novel dance leg pressing device for sports training.

[0006] In order to achieve the above purpose, the technical scheme of the utility model is as follows:

[0007] A novel dance leg pressing device for sports training comprises a leg pressing rod and a U-shaped seat installed on the upper part of the leg pressing rod.

[0008] An adjustment seat is arranged on the leg pressing rod, a through hole is formed in the adjustment seat along the vertical direction, a supporting rod is slidably installed in the through hole, and the U-shaped seat is installed at the top end of the supporting rod.

[0009] An adjustment groove is formed in the side surface of the supporting rod along the length direction of the supporting rod, and a clamping groove is formed in the side surface of the adjustment groove and inclined upward.

[0010] A clamping pin one is arranged in the through hole of the adjustment seat and can move between the adjustment groove and the clamping groove, and when the clamping pin one is clamped at the end of the clamping groove, the connecting line between the top ends of the U-shaped seat is parallel to the length direction of the leg pressing rod.

[0011] Preferably, the adjusting seat lower part is sleeved with an annular auxiliary sleeve, the auxiliary sleeve is internally provided with a clamping pin two movable between the adjusting grooves and the clamping grooves; the adjusting seat and the auxiliary sleeve are connected with a coil spring, and when the clamping pin one is clamped at the end of the clamping groove, the coil spring is in a deformed state, and the restoring force of the deformed state makes the clamping pin two clamped at the end of the clamping groove.

[0012] Preferably, the distance between the clamping pin one and the clamping pin two in the vertical direction is an integer multiple of the distance between the adjacent two groups of clamping grooves.

[0013] Preferably, the adjusting seat lower part is provided with a connecting part sleeved with the auxiliary sleeve, and a clamping ring is arranged outside the connecting part, and the inside of the auxiliary sleeve is provided with a rotating groove clamped with the clamping ring.

[0014] Preferably, the two ends of the leg pressing rod are fixedly connected with the vertical stand, and the included angle between the clamping groove and the adjusting groove is 30°-45°.

[0015] Preferably, the U-shaped seat is internally provided with a buffer pad made of rubber material.

[0016] Compared with the prior art, the beneficial effects of the present application are:

[0017] 1. The clamping pin one can move in the adjusting groove and the clamping groove, and the multi-gear height adjustment of the U-shaped seat is realized by fixing the clamping pin one in the clamping groove at different heights. This design can meet the height and flexibility requirements of different users, and ensure the stability and reliability of the adjusted height.

[0018] 2. When the clamping pin one is clamped at the end of the clamping groove, the connecting line between the top ends of the U-shaped seat is parallel to the length direction of the leg pressing rod, ensuring that the U-shaped seat is directly opposite the user. This design avoids the inconvenience or poor training effect caused by angle deviation of the traditional leg pressing device, and improves the practicability and user experience of the device.

[0019] 3. During use, when the user presses the leg downward, the U-shaped seat is subjected to a downward force, which is transmitted to the clamping pin one through the supporting rod, so that the clamping pin one is pressed more tightly in the clamping groove. This self-locking mechanism enhances the stability and safety of the device, avoids loosening or sliding caused by external force, and ensures the safety and reliability of the training process.

DETAILED DESCRIPTION

[0026] It is easy to understand that according to the technical scheme of the utility model, a person skilled in the art can propose a plurality of structure modes and implementation modes that can be replaced with each other without changing the essential spirit of the utility model. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole or regarded as the limitation or restriction of the technical scheme of the utility model.

[0027] EMBODIMENT

[0028] As Figure 1 shown, a new dance leg pressing device for sports training includes leg pressing rod 1, support rod 2, U-shaped seat 23, adjusting seat 11, auxiliary sleeve 3 and coil spring 4 and other main components. The two ends of leg pressing rod 1 are fixedly connected with vertical vertical rod 12, forming a stable support frame. Adjusting seat 11 is installed on leg pressing rod 1, support rod 2 is slidingly installed in the through hole of adjusting seat 11, U-shaped seat 23 is fixed at the top end of support rod 2, used for supporting the leg of the user.

[0029] As Figure 2 shown, the side surface of support rod 2 is provided with adjusting groove 21 along the length direction thereof, a plurality of clamping grooves 22 are obliquely upwardly provided on the side surface of adjusting groove 21, and the included angle between clamping groove 22 and adjusting groove 21 is 30°-45°. Pin one 15 is arranged in the through hole of adjusting seat 11, and pin one 15 is movable between adjusting groove 21 and clamping groove 22. When pin one 15 is clamped into the end part of a clamping groove 22 of a certain height, support rod 2 is locked at the height, and the connecting line between the top ends of U-shaped seat 23 is parallel to the length direction of leg pressing rod 1, ensuring that U-shaped seat 23 is directly opposite to the user, avoiding angle deviation. Buffer pad 24 is arranged in U-shaped seat 23, buffer pad 24 is made of rubber material, and can effectively reduce the impact force when the leg of the dancer contacts U-shaped seat 23, improving the comfort of training.

[0030] During use, when the user presses their leg down, the U-shaped seat 23 is subjected to a downward force. This force is transmitted through the support rod 2 to the locking pin 15 and locking pin 32, making them press more tightly in the locking groove 22, further enhancing the stability of the device.

[0031] like Figure 3 , Figure 4 As shown, an annular auxiliary sleeve 3 is fitted onto the lower part of the adjusting seat 11. A second locking pin 32 is provided inside the auxiliary sleeve 3, and the second locking pin 32 can also move between the adjusting groove 21 and the locking slot 22. The vertical distance between the first locking pin 15 and the second locking pin 32 is an integer multiple of the distance between two adjacent sets of locking slots 22, ensuring that both can simultaneously engage with locking slots 22 of different heights.

[0032] A coil spring 4 connects the adjusting seat 11 and the auxiliary sleeve 3. When the locking pin 15 is engaged at the end of the slot 22, the coil spring 4 is in a deformed state. The restoring force of the deformed state causes the locking pin 32 to engage at the end of the slot 22, further enhancing the stability of the device. In actual use, the coil spring 4 ensures stability between the auxiliary sleeve 3 and the adjusting seat 11 when adjusting the support rod 2, preventing the auxiliary sleeve 3 from obstructing the adjustment of the support rod 2 due to the compression or stretching of the coil spring 4, thus providing a certain locking effect.

[0033] The lower part of the adjusting seat 11 is provided with a connecting part 13 that fits into the auxiliary sleeve 3. A retaining ring 14 is provided on the outside of the connecting part 13. The inner side of the auxiliary sleeve 3 is provided with a rotating groove 31 that engages with the retaining ring 14, ensuring a firm connection while ensuring that the auxiliary sleeve 3 and the adjusting seat 11 are rotatably connected.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
