Description

Technical Field

[0001] The utility model relates to the field of fitness products, in particular to an elastic band length adjustment handle. Background Art

[0002] Elastic bands are an elastic tool widely used in fitness and rehabilitation training. They are made of highly elastic materials and are portable and versatile. Existing elastic band handles are fixed or buckled at both ends of the elastic band, providing comfortable gripping points, but the length of the elastic band cannot be adjusted. Since different exercise movements and intensities require the use of elastic bands of different lengths, and the existing fixed-length design requires users to adjust the length by holding the elastic band at different positions. This method of use will cause obvious discomfort in the hands when exerting force and is not convenient for adjusting the appropriate gripping posture. Alternatively, one end of the elastic band needs to be fixed, such as in the gap of the door frame, to adjust the appropriate exercise direction. However, this method has low flexibility and is not convenient for exercising anytime and anywhere. If the firmness of the fixed position is not clear, there are also safety hazards. Summary of the invention

[0003] The utility model aims to solve the problems of the above-mentioned technology that the length of the elastic band cannot be adjusted, the use is uncomfortable and inflexible, and proposes an elastic band length adjustment handle.

[0004] The utility model adopts the following technical solutions:

[0005] The elastic band length adjustment handle includes a fixed box body and a movable box body, which are assembled into a complete handle box body. Notches are opened at both ends of the fixed box body, and a support groove is opened on the edge. Two groups of winding columns are arranged on the inner wall for adjusting the length of the elastic band by winding. Notches are opened at both ends of the movable box body, which match the notches of the fixed box body and are assembled into openings at both ends of the handle box body for the elastic band to extend from the handle box body. Supports are arranged on the edge of the movable box body, and the supports are slidably embedded in the support grooves, so that the two box bodies are fixed to each other, and support the adjustment of the width of the handle box body by separating the two box bodies to adapt to elastic bands of different widths.

[0006] In a possible design, the two groups of winding columns are respectively composed of two plate-like bodies, and the fixed ends of the winding columns are provided with reinforcement piers, which are used to increase the strength of the winding columns.

[0007] In a possible design, two plate-shaped reinforcement columns are provided on the inner wall of the movable box body, and the reinforcement columns are slidably embedded between the plate-shaped bodies of the winding column to increase the strength of the winding column and cooperate with the support column to adjust the handle width.

[0008] In a possible design, the notches at both ends of the fixed box body and the movable box body are arc-shaped, and the openings at both ends of the assembled handle box body are curved, which is used to reduce the friction between the elastic band and the opening of the handle box body.

[0009] In a possible design, the support includes four cylinders, which are respectively arranged on both sides of the notch at both ends of the movable box body, and the support grooves are respectively opened on both sides of the notch at both ends of the fixed box body.

[0010] In a possible design, outer walls of the fixed box body and the movable box body are arc-shaped to provide a better grip.

[0011] In the present application, when in use, the user first wraps the elastic band around the outer wall of any group of winding columns for half a circle, then pinches the elastic bands on both sides of the winding column, wraps it around the outer wall of another group of winding columns for half a circle clockwise or counterclockwise, and continues to wrap around the two groups of winding columns. After adjusting the length by winding, the elastic bands are placed in the gaps at both ends of the fixed box body or uniformly placed in the gaps at the same end, and then the fixed box body and the movable box body are assembled by sliding the gaps between the pillars and the pillar grooves and the reinforcement pillars and the plate-like bodies of the winding columns. The user can adjust the length of the elastic band by a handle or a combination of two handles according to specific needs. Beneficial Effects

[0012] In the utility model, the elastic band length adjustment handle enables the user to easily adjust the length of the elastic band by winding the elastic band around the winding column; the plate-shaped design of the winding column ensures the strength of the winding column, while reducing the occupation of the effective winding space by the winding column, increasing the number of circles that the elastic band can be wound in the handle box body, and expanding the length adjustment range.

[0013] In the utility model, the elastic band length adjustment handle and the opening design at both ends of the handle box body support the user to extend the elastic band from one or two openings according to needs, so as to obtain the desired holding method; the arc shape of the outer wall of the handle box body provides a better gripping feeling, avoiding discomfort in the hands when pulling with force.

[0014] In the utility model, the elastic band length adjustment handle supports the user to adjust the width of the handle box body through the design of the support column and the reinforcement column, so that the handle can adapt to elastic bands of different widths.
