[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

[0024] In the description of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0026] This embodiment aims to provide a stretching equipment for sports training, whose main function is to be simple and practical in construction and extremely convenient to use.

[0027] Reference Figure 1 and Figure 2 It includes: a pair of foot seats 1, a main support arm, a secondary support arm 4, an elastic band 5, and a positioning column 6. The two foot seats 1 are corresponding to each other and parallel. Rollers 2 are installed at the four corners of the bottom of the foot seats 1. The foot seats 1 can be fixed and moved laterally through the rollers 2. The side of the two foot seats 1 that is close to each other is provided with a baffle 7 to prevent the trainee from slipping off the foot seats 1 when exerting force with both feet towards the middle.

[0028] The main support arm is horizontally positioned between two foot seats 1. The main support arm consists of a pair of hinged struts 3, with the ends of the two struts 3 that are far apart from each other being hinged to the corresponding foot seats 1. Thus, the hinge joints of the two struts 3 can be arched upward by the reverse displacement of the two foot seats 1. The secondary support arm 4 is horizontally positioned above the main support arm, with the extension direction of the secondary support arm 4 perpendicular to the extension direction of the main support arm. Multiple secondary support arms are distributed at intervals along the extension direction of the secondary support arms 4. The bottom of the secondary support arm 4 is provided with a hinge plate 8 so that the hinge plate 8 is hinged together with the hinge joints of the two struts 3, thereby allowing the secondary support arm 4 and the hinge joints of the two struts 3 to move synchronously.

[0029] The elastic band 5 is located between the two feet 1, and the two ends of the elastic band 5 are fixed to the two feet 1 respectively. Multiple elastic bands 5 are distributed at intervals along the extension direction of the top support arm 4. The elastic band 5 is located at the interval between two adjacent top support arms. The top support arm 4 is located below the middle of the elastic band 5. When the top support arm 4 moves upward, it will support the middle of the elastic band 5 upward. Since the top support arm 4 is a cylindrical tube with a smooth outer wall, it will not cause wear to the elastic band 5.

[0030] Reference Figure 2 and Figure 3 The positioning column 6 is vertically positioned, with its lower end penetrating the middle of the top support arm 4 and contacting the ground. This allows the top support arm 4 to move axially along the positioning column 6, ensuring its position. The lower end of the positioning column 6 is equipped with a base 9 to increase the contact area between the lower end of the positioning column 6 and the ground, enhancing its stability. The upper end of the positioning column 6 is equipped with a horizontal grip bar 10, which forms a cross shape with the positioning column 6. The extension direction of the grip bar 10 is consistent with the length direction of the elastic band 5, allowing the trainee to hold the two ends of the grip bar 10 with both hands to maintain a stable body posture.

[0031] In this embodiment, a lifting plate 11 is provided at the bottom of the positioning column 6. The lifting plate 11 is located at the bottom of the top support arm 4. The lifting top support arm 4 is used to arch the hinge of the two support rods 3 upwards. The purpose is to limit the initial hinge state of the two support rods 3 so as to ensure that when the two feet 1 move synchronously towards the middle, the displacement direction of the hinge of the two support rods 3 must be upward, making it more convenient to use.

[0032] When using it, the trainee places both feet on the two footrests 1 respectively, maintains a semi-squatting posture, and holds the two ends of the handle bar 10 with both hands. Then, the trainee exerts force with their feet to move towards the middle. The middle part of the elastic band 5 will be supported upward by the support arm 4, which means that the moving resistance of the two footrests 1 will become greater and greater. By repeatedly moving the two footrests 1 in opposite directions, the training purpose can be achieved.

[0033] The stretching equipment provided in this embodiment is simple and practical in structure, inexpensive, very convenient to move, does not take up too much training space, and has excellent effects.

[0034] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
