Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a stretching device. Background Art

[0002] A stretching board is a kind of fitness equipment, mainly used for stretching and relaxing the muscles of the body, improving flexibility and pliability. Regular use of the stretching board can effectively improve the body's pliability and enhance the range of motion of joints; stretching with the stretching board before exercise can reduce the risk of injury during exercise, especially when performing high-intensity training; the use of the stretching board also helps to relax the body and mind and relieve the stress and tension brought by work or exercise.

[0003] The existing stretching board has a single function and can only be used for stretching at a fixed specific angle (fixed stretching), and cannot stretch and relax the body muscles in a way other than the fixed angle. There is also a footrest under the table mainly used for relaxing after sitting for a long time in the office and preventing cross-legged sitting. The footrest under the table specifically includes a pedal and stool legs arranged on the pedal. The part of the stool legs in contact with the ground is in an arc structure. Placing the footrest under the table, stepping on the pedal with both legs, and rocking the legs back and forth can stretch and relax the body muscles, but fixed stretching cannot be achieved. That is, the existing devices for stretching and relaxing the body muscles have limited functions and cannot achieve both fixed stretching and rocking the legs back and forth at the same time. Summary of the Utility Model

[0004] The utility model aims at the above problems and provides a stretching device.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The present application provides a stretching device, including a base, a stretching board and an adjusting member;

[0007] The stretching board is rotatably arranged on the base;

[0008] The adjusting member is located between the base and the stretching board. The adjusting member includes an abutting portion. The adjusting member is movably arranged on the base, and the adjusting member has a first working position and a second working position:

[0009] When the adjusting member is in the first working position, it rotates with the stretching board, and there is no contact between the abutting portion and the stretching board;

[0010] When the adjusting member is in the second working position, it rotates with the stretching board, and the abutting portion can contact the stretching board and limit the stretching board from continuing to rotate towards the side of the abutting portion.

[0011] When the adjusting member is in the first working position, the adjusting member does not prevent the stretching plate from rotating, that is, the stretching plate can rotate freely. The user can apply forces in different directions to the stretching plate to achieve a back-and-forth rocking movement mode, namely the front-and-back rocking mode of the feet of the muscle stretching device. This mode is convenient for the user to relax. In particular, it can be used as a footrest in the office, that is: in a sitting position, place the feet on the stretching plate and rock back and forth to move, exercise and relax the legs; avoid the discomfort caused to the legs by sitting for a long time at work, and prevent crossing the legs. At the same time, this relaxation activity will not affect work, and one can relax and exercise while working, killing two birds with one stone. In actual use, in addition to the office, it can also be used in other similar occasions, such as at home, placed in front of the sofa to relax while watching TV.

[0012] When the adjusting member is in the second working position, the adjusting member will prevent the stretching plate from continuing to rotate towards the abutting portion. That is, when the user's center of gravity biases towards the abutting portion, the stretching plate will abut against the abutting portion during the rotation process, enabling the muscle stretching device to achieve fixed muscle stretching, namely the feet stretching mode of the muscle stretching device. This mode is convenient for the user to deeply stretch and relax the muscles.

[0013] By setting the adjusting member and enabling the adjusting member to have different working positions, the muscle stretching device can simultaneously achieve the front-and-back rocking mode of the feet and the fixed feet stretching mode, enhancing the functional modes of the muscle stretching device.

[0021] Further, a locking member is connected to the adjusting part. After the adjusting part is adjusted to the first working position or the second working position, the locking member is used to fix the adjusting part to the base. Specifically, the locking member can be a detachable fastener.

[0022] Alternatively, the adjusting part is rotatably arranged on the base. By rotating the adjusting part, the abutting part is brought into contact with or separated from the stretching plate, and at the same time, the position of the abutting part relative to the base is locked, so that the adjusting part is in the first working position or the second working position.

[0023] Or, the adjusting part is a telescopic structure. When the adjusting part is in the contracted state, it cannot contact the rotating stretching plate, and the adjusting part is in the first working position; when the adjusting part is in the extended state, it can contact the rotating stretching plate and make the stretching plate abut against the adjusting part, and the adjusting part is in the second working position.

[0024] Further, the adjusting part includes a cross plate and a hand-held protrusion.

[0056] Embodiment 1

[0057] As Figures 1 to 7 shown, the present application provides a tensioning device, including a base 10, a stretching plate 20 and an adjusting member 40;

[0058] The stretching plate 20 is rotatably arranged on the base 10;

[0059] The adjusting member 40 is located between the base 10 and the stretching plate 20. The adjusting member 40 includes an abutting part 420. The adjusting member 40 is movably arranged on the base 10, and the adjusting member 40 has a first working position and a second working position:

[0060] As Figure 1 and Figure 2 shown, when the adjusting member 40 is in the first working position, it rotates with the stretching plate 20, and there is no contact between the abutting part 420 and the stretching plate 20;

[0061] like Figure 3 and Figure 4 As shown, when the adjusting member 40 is located at the second working position, as the stretching plate 20 rotates, the abutting portion 420 can contact the stretching plate 20 and restrict the stretching plate 20 from continuing to rotate toward the abutting portion 420 side.

[0062] When the adjusting member 40 is located at the first working position, the adjusting member 40 does not hinder the rotation of the stretching board 20, that is, the stretching board 20 can rotate freely, and the user can achieve a forward and backward swinging activity mode by applying forces in different directions to the stretching board 20, that is, the forward and backward swinging mode of the feet of the stretching device, which is convenient for the user to relax;

[0063] When the adjustment member 40 is located in the second working position, the adjustment member 40 will prevent the stretching plate 20 from continuing to rotate toward the side of the abutment portion 420, that is, when the user's center of gravity is biased toward the side of the abutment portion 420, the stretching plate 20 will abut against the abutment portion 420 during rotation, so that the stretching device can achieve fixed stretching, that is, the double-foot stretching mode of the stretching device. This mode is convenient for users to deeply stretch and relax their muscles.

[0064] By providing the adjusting member 40 and making the adjusting member 40 have different working positions, the stretching device can realize both the forward and backward rocking mode of the feet and the stretching mode of the feet at the same time, and the functional mode of the stretching device is enhanced.

When the clamping column 411 engages with different clamping slots 120, the abutting portion 420 has different lateral positions relative to the stretching plate 20.

[0067] In this embodiment, when the clamping column 411 is clamped with the clamping slot 120 that is closer to the inside, the distance between the abutting portion 420 and the rotation axis of the stretching plate 20 is larger, and the inclination angle of the stretching plate 20 in the double-foot stretching mode is smaller.

[0068] When the clamping column 411 is clamped with the outermost clamping groove 120, the abutting portion 420 is just located below the rotation axis of the stretching plate 20, so that the adjustment member 40 is located in the first working position and the tendon stretching device is in a double-foot forward and backward swinging mode.

[0069] In other embodiments, a clamping groove 120 is provided on the adjusting part 410, and six clamping posts 411 are provided on the base 10 at intervals. The clamping groove 120 is used for clamping and cooperating with each clamping post 411 respectively, and the adjusting member 40 is movably clamped on the base 10 through the adjusting part 410.

[0070] The adjusting member 40 is movably arranged on the base 10 in a clamping manner, with a simple structure and convenient adjustment. When the stretching device is in the double-foot stretching mode, the clamping structure is also more stable.

[0071] In this embodiment, a guiding sliding groove 130 is formed on the base 10. The length direction of the guiding sliding groove 130 is perpendicular to the rotation axis of the stretching plate 20, and a plurality of clamping grooves 120 or clamping posts 411 are arranged at intervals along the length direction of the guiding sliding groove 130;

[0072] The adjusting member 40 is slidably arranged on the base 10 through a guiding sliding rail.

[0073] In this embodiment, convex edges are formed on both sides of the cross plate 412 of the adjusting part 410. The convex edges are used to cooperate with the guiding sliding groove 130, so that the adjusting member 40 can slide along the guiding sliding groove 130, facilitating the adjustment of the position of the clamping post 411 or the clamping groove 120 on the adjusting part 410 on the base 10.

[0074] In this embodiment, the adjusting part 410 includes a cross plate 412 and a hand-held protrusion 413. One end of the cross plate 412 is connected to the abutting part 420, and the other end is connected to the hand-held protrusion 413. The hand-held protrusion 413 protrudes from the cross plate 412, and the hand-held protrusion 413 is convenient for the user to use the hand to lift or press down the adjusting part 410 during operation;

[0075] The clamping post 411 is arranged on the hand-held protrusion 413.

[0076] In this embodiment, the clamping post 411 is arranged on the bottom surface of the hand-held protrusion 413.

[0077] In this embodiment, the clamping post 411 protrudes from the cross plate 412.

[0079] In this embodiment, a rotating shaft 30 is further included. A supporting wall 110 is formed on the base 10, and a mounting hole 111 is formed on the supporting wall 110;

[0080] The stretching plate 20 is installed on the rotating shaft 30 through the rotating shaft groove 210, and the rotating shaft 30 is rotatably installed on the support wall 110 through the installation hole 111. That is: the rotating shaft 30 passes through the rotating shaft groove 210, and both ends of the rotating shaft 30 are respectively rotatably installed on the corresponding support walls 110 on both sides thereof.

[0081] In other embodiments, the stretching plate 20 may also be provided with a rotating shaft hole.

[0082] In this embodiment, the rotating shaft 30 and the installation hole 111 are coaxially arranged, and the axis of the rotating shaft 30 is the rotation axis of the stretching plate 20.

[0083] In this embodiment, the support wall 110 is arranged along the height direction of the base 10;

[0084] An opening is provided on the support wall 110, and the opening is communicated with the guiding sliding groove 130 to facilitate the movement of the adjusting member 40 on the base 10.

[0085] In actual use, the rotating shaft 30 and the stretching plate 20 may be integrally formed. Or, the rotating shaft 30 is fixed to the support wall 110, and the installation hole 111 is provided on the stretching plate 20. In actual use, the rotating shaft 30 and the support wall 110 are also integrally formed.

[0086] In this embodiment, the stretching plate 20 is formed with an anti-slip-off wall 220 along the height direction, and a protective layer 230 is formed inside the anti-slip-off wall 220. The protective layer 230 is used to prevent abrasion of the user's heel.

[0095] When the adjusting member 40 is in the second working position, the telescopic column 430 is in an extended state and together with the abutting part 420 supports the stretching plate 20.

[0096] The setting of the telescopic column 430 can improve the stability of the stretching device. When the user gets off the stretching plate 20, it can prevent the situation of falling forward due to the center of gravity moving forward. That is, the setting of the telescopic column 430 improves the safety of the stretching device. Example 3
