Description

Technical Field

[0001] This utility model relates to the field of training equipment technology, specifically a cross-rope strength training device. Background Art

[0002] A figure-eight pull rope, also known as a figure-eight cable puller, is a piece of exercise equipment, also known as a clamp, consisting of two iron or wooden handles connected by an elastic cord. Using a figure-eight cable puller can improve arm, wrist, and grip strength because it requires the use of arm and grip strength to stretch the rope, which in turn strengthens the upper body muscles.

[0003] In the prior art, a tensioner with publication number CN217908759U adopts a scheme that "includes an integrally formed intermediate body and a first grip body and a second grip body arranged on both sides of the intermediate body, and the upper and lower surfaces of the rear end of the first grip body and the upper and lower surfaces of the front end of the second grip body are both provided with anti-fracture components, and the anti-fracture components include upper and lower semi-circular tubular body sleeves arranged opposite each other, and a corrugated flexible cushion layer is welded inside the body sleeve through the sections." This scheme, by providing an anti-fracture component, wraps the first grip body and the second grip body around the intermediate body section, thereby enhancing their anti-fracture strength. Through the corrugated flexible cushion layer, if the surface of the first grip body or the second grip body is broken, the broken part is firmly clamped in the body sleeve to prepare for continued use of the tensioner, with good anti-fracture performance. The first grip body, the second grip body and the intermediate body are arranged in one piece, which is not only simple in structure but also easy to carry.

[0004] However, the above solution still has some shortcomings. For example, in actual use, it can only train the hands by pulling the tensioner with both hands, and it is impossible to train the hands and feet at the same time during the actual training process. That is, the technical solution proposed by the above patent technology has the defect of a single training function.

[0005] In view of this, the present invention proposes a cross-rope strength training device. Utility Model Content

[0006] The purpose of this invention is to provide a cross-rope strength training device that has the advantage of being able to train both hands and feet simultaneously, thereby solving the problem of the single training function mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cross rope strength trainer includes an upper cover and a lower cover, which are arranged in a cross shape, and elastic ropes are fixed at both ends of the upper cover and the lower cover. The middle surfaces of the four elastic ropes are all provided with handles, and the surface of the lower cover is provided with a safety lock for locking the upper cover and the lower cover.

[0009] As a preferred technical solution, the handle is made of flexible foam or soft plastic molding, and a number of notches are equidistantly provided on both side surfaces of the handle to facilitate bending of the handle as a whole.

[0010] As a preferred technical solution, a snap-in groove is provided on the upper surface of the lower cover for facilitating snap-in connection with the upper cover.

[0011] As a preferred technical solution, the safety lock includes a sliding groove opened on the surface of the lower cover, and a locking block that is slidably arranged on the inner wall of the sliding groove and is elastic.

[0012] As a preferred technical solution, the locking block is linked to a paddle button for elastically pressing inward, and a sliding cover is provided next to the paddle button for shielding or exposing the paddle button switch.

[0013] As a preferred technical solution, a positioning strip is fixedly provided on one side surface of the lower cover, and a positioning groove adapted to the positioning strip is opened on the side surface of the upper cover. Beneficial effects

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The technical solution proposed by the utility model is an improvement on the traditional figure-eight pull rope. The upper cover and the lower cover of the cross structure are buckled together to form a 90° angle. This design enables the elastic rope to be stretched to any angle, and the cross structure can better bear the force, which is more practical.

[0016] The technical solution proposed by the present invention is that after the upper cover and the lower cover of the cross structure are buckled together, the four elastic ropes form a cross-shaped tension training device. Such a combination can not only enhance strength training, but also can train hands and feet together while completing various sports movements, effectively solving the defect of single training function in the existing technology.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] According to the attached Figure 1-5 As shown, an embodiment of the utility model provides a cross rope strength trainer, including an upper cover 1 and a lower cover 2. The upper surface of the lower cover 2 is provided with a snap-in groove 7 for facilitating the snap-in of the upper cover 1. The setting of the snap-in groove 7 facilitates that the upper cover 1 and the lower cover 2 can form a cross-shaped structure after they are snapped together.

[0027] A positioning bar 8 for positioning the upper cover 1 is fixedly provided on one side surface of the lower cover 2 , and a positioning groove 9 adapted to the positioning bar 8 is opened on the side surface of the upper cover 1 .

[0028] The upper and lower covers 1 and 2 are arranged in a cross-shaped configuration. Elastic cords 3 are fixed to each end of the upper and lower covers 1 and 2 for easy pulling. Handles 4 are mounted in the middle of each of the four elastic cords 3. These handles 4 are molded from flexible foam or injection-molded soft plastic. Several notches 6 are evenly spaced on either side of the handles 4 to facilitate bending. This allows the handles 4 to bend when the elastic cords 3 are pulled, improving grip.

[0029] The lower cover 2 is provided with a safety latch 5 for locking the upper cover 1 and lower cover 2. The safety latch 5 comprises a sliding groove formed in the lower cover 2 and a spring-loaded locking block 501 (also known as a locking tongue) slidably mounted within the inner wall of the sliding groove. The upper cover 1 is provided with a locking groove adapted to mate with the locking block 501. A paddle button 502 is provided around the locking block 501 for elastically pressing inward. In practice, a 90-degree bend in the spring arm structure allows the locking block to slide inward along the sliding groove when the paddle button is pressed downward, and to return and extend when the pressure is released. A sliding cover 503 is provided adjacent to the paddle button 502 to shield or expose the paddle button during operation. This cover can be opened to expose the paddle button when the upper and lower covers are disassembled. When the disassembly and assembly are completed and the exercise is performed, it is preferred to move the sliding cover to completely cover the paddle button, so as to prevent people from accidentally touching the paddle button 502 and causing the upper cover 1 and the lower cover 2 to separate suddenly.

[0030] When buckling the upper cover 1 and the lower cover 2, first push the locking block 501 outward and buckle the upper cover 1 into the snap-fit ​​groove 7, so that the positioning bar 8 on the lower cover 2 is inserted into the positioning groove 9 on the upper cover 1, and then push the locking block 501 inward so that the end of the locking block 501 enters the locking groove on the upper cover 1, and slide the sliding cover 503 outward to expose the paddle button 502. Press the paddle button 502 to lock the locking block 501, and then reset the sliding cover 503 to achieve the quick buckling combination between the upper cover 1 and the lower cover 2.

[0031] The technical solution proposed by the present invention is an improvement on the traditional figure-eight pull rope. The upper cover 1 and the lower cover 2 of the cross structure are buckled together to form an angle of 90°. This design allows the elastic rope 3 to be stretched to any angle, and the cross structure can better withstand force, which is more practical. After the upper cover 1 and the lower cover 2 of the cross structure are buckled together, the four elastic ropes 3 form a cross-shaped tension training device. Such a combination can not only enhance strength training, but also can train hands and feet together while completing various sports training, effectively solving the defect of single training function in the existing technology.
