Description

Technical Field

[0001] This utility model relates to the field of sports stretching equipment technology, and in particular to a sports stretching device that is easy to adjust. Background Technology

[0002] Sports stretching is a form of fitness exercise that improves the coordination between ligaments, muscles, and joints, reducing the risk of injury. Stretching involves using equipment to maintain a certain extended position, providing a slow, relaxing stretch that also reduces nerve and muscle excitability. It's a good method for relaxation after exercise. However, existing sports stretching devices have at least the following drawbacks: 1. Due to the widespread popularity of fitness among adults, children, and the elderly, traditional stretching devices use fixed-height and fixed-width bars, making them inconvenient for shorter users and increasing the risk of injury. 2. Most existing sports stretching devices include benches for assistance with stretching and rest, but these are fixed to the ground. Excessive stretching can lead to bumps and collisions, limiting the user's movement. Therefore, we are introducing a new, easily adjustable sports stretching device. Utility Model Content

[0003] The main purpose of this invention is to provide an easily adjustable sports stretching device that can effectively solve the problems in the background art.

[0007] Preferably, the upper limb stretching device includes a square crossbar, with a through transverse slide rail at the middle of the upper end of the square crossbar. The upper part of the inner wall of the transverse slide rail has several slots, and two I-shaped sliders are slidably connected inside the transverse slide rail. The outer surfaces of the two I-shaped sliders each have a limit groove and are respectively engaged with the two slots.

[0008] Preferably, the left and right ends of the square crossbar are fixedly connected to two L-shaped load-bearing bars, and the lower ends of the two I-shaped sliders are fixedly connected to two tension rings.

[0009] Preferably, the adjustment device includes a sliding base, with universal wheels fixedly installed at the four corners of the lower end of the sliding base, a soft stool fixedly installed at the middle of the upper end of the sliding base, and a movable telescopic rod fixedly installed at the middle of the rear end of the sliding base.

[0010] Preferably, the rear part of the outer surface of the soft stool is movably connected to the rotating groove, and the middle part of the front end of the sliding base is fixedly connected to the handle.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, the drive motor is turned on by the lifting control panel, so that the spiral rod drives the two sides of the limiting and fixing crossbar to slide up and down in the two cross slide rails, thereby driving the lower limb stretching crossbar and the upper limb stretching device to slowly rise and fall, thereby adjusting different heights to meet the needs of users of different heights. When the I-shaped slider moves upward, it can slide to the required width between the two slots. After selecting the appropriate width, it is locked into the corresponding slot for limiting, so that stretchers with different shoulder widths can use it, reducing unnecessary dangers caused by different body shapes when using it.

[0013] 2. In this utility model, the movable telescopic rod is connected to the rotating groove. During use, the sliding base can be easily dragged by the handle to adjust the position of the entire adjustment device. When dragging, the brake of the universal wheel can be released to slide the position. When the desired position is reached, the four universal wheels are locked at the same time to prevent movement during use. This makes the entire tensioning device flexible and easy to adjust.

A handle 9 is fixedly installed at the middle of the front end of the adjusting device 8. A lifting control panel 6 is fixedly installed at the lower front end of the counterweight base 1.

[0025] In this embodiment, the stretching mechanism 5 includes a drive motor 501. A spiral rod 502 is fixedly installed at the output end of the drive motor 501. A limiting and fixing crossbar 503 is threadedly connected to the outer surface of the spiral rod 502. A lower limb stretching crossbar 506 is fixedly installed at the rear end of the limiting and fixing crossbar 503. L-shaped load-bearing rods 504 are fixedly installed at the left and right front ends of the limiting and fixing crossbar 503. An upper limb stretching device 505 is fixedly connected between the two L-shaped load-bearing rods 504.

A through transverse slide rail 52 is opened in the middle of the upper end of the square crossbar 51. Several slots 53 are opened in the upper part of the inner wall of the transverse slide rail 52. Two I-shaped sliders 54 are slidably connected inside the transverse slide rail 52. The outer surfaces of the two I-shaped sliders 54 are opened with limiting grooves and are respectively connected to two... The upper limb stretching device 505 includes a square crossbar 51, with a through transverse slide rail 52 at the middle of the upper end of the square crossbar 51. Several slots 53 are opened on the upper part of the inner wall of the transverse slide rail 52. Two I-shaped sliders 54 are slidably connected inside the transverse slide rail 52. The outer surfaces of the two I-shaped sliders 54 are opened with limit grooves and are respectively engaged with the two slots 53. The drive motor 501 is controlled by the lifting control panel 6. When the drive motor 501 is started, the limit fixing crossbar 503, which is threaded through the spiral rod 502, drives the entire limit fixing crossbar 503 to slide within the two cross slide rails 4. The interior of the cross slide rail 4 is a cross-shaped groove. The lower limb stretching crossbar 506 and the L-shaped load-bearing rod 504 connected to the left side of the outer surface of the limit fixing crossbar 503 form a cross slider that slides up and down within the cross slide rail 4, thereby adjusting the height of the lower limb stretching crossbar 506 and the stretching ring 507.

[0026] In this embodiment, the adjustment device 8 includes a sliding base 801, with casters 802 fixedly installed at the four corners of the lower end of the sliding base 801. A soft stool 804 is fixedly installed at the middle of the upper end of the sliding base 801, and a movable telescopic rod 803 is fixedly installed at the middle of the rear end of the sliding base 801. The rear part of the outer surface of the soft stool 804 is movably connected to the rotating groove 7, and the middle of the front end of the sliding base 801 is fixedly connected to the handle 9. The movable telescopic rod 803 is movably connected to the rotating groove 7. During use, the sliding base 801 can be easily dragged through the handle 9 to adjust the position of the entire adjustment device 8. When dragging, the brakes on the casters 802 can be released to slide the device to the desired position. When the desired position is reached, all four casters 802 are locked simultaneously to prevent movement during use, thus making the entire tensioning device flexible and easy to adjust.

[0027] It should be noted that this utility model is a sports stretching device that is easy to adjust. During use, the drive motor 501 is first turned on via the lifting control panel 6, which causes the spiral rod 502 to drive the two sides of the limiting and fixing crossbar 503 to slide up and down within the two cross slide rails 4. The cross slide rail 4 has a cross-shaped groove inside. The lower limb stretching crossbar 506 and the L-shaped load-bearing rod 504 connected to the left side of the outer surface of the limiting and fixing crossbar 503 form a cross slider that slides up and down within the cross slide rail 4, thereby adjusting the height of the lower limb stretching crossbar 506 and the stretching ring 507, which in turn causes the lower limb stretching crossbar 506 and the upper limb stretching device 505 to slowly move upward. Raising and lowering the I-shaped slider 54 upwards causes it to disengage from the slot 53 and slide within the transverse slide rail 52 to the required width between two I-shaped sliders 54. After selecting the appropriate width, it is engaged with the corresponding slot 53 for limiting. The universal wheels 802 are first released from their braking state to allow sliding. When the desired position is reached, all four universal wheels 802 are simultaneously locked. In the locked state, no movement occurs during stretching. The sliding base 801 is then dragged to the desired position. The universal wheels 802 are first released from their braking state to allow sliding. This makes the entire stretching device flexible and easy to adjust, allowing it to be used by stretching exercisers of different body types and reducing the risk of use.
