Description

Technical Field

[0001] The utility model relates to the technical field of sports training, in particular to a muscle stretching device for sports training. Background Art

[0002] Physical training refers to physical activities that people choose based on their physical needs, use various physical means, and combine natural forces and hygiene measures to develop the body, improve health, enhance physical fitness, regulate the mind, enrich cultural life and manage leisure time. However, if muscles are not stretched for a long time during physical training, it is easy to cause muscle strain. Therefore, it is necessary to use muscle stretching devices to stretch the muscles.

[0003] The Chinese patent "A muscle stretching device for sports training" authorization announcement number "CN216366520U" rotates the lifting rod to make the lifting rod move vertically in the positioning rod, thereby driving the pull ring to adjust the height, allowing users of different body shapes to use the device conveniently, thereby enhancing the practicality of the muscle stretching device.

[0004] Although the height of the pull ring can be adjusted by rotating the lifting rod, the user cannot clearly know the specific height of the pull ring required during the adjustment, which results in the user having to make repeated adjustments, which is rather cumbersome.

[0005] Therefore, a muscle stretching device for sports training is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a muscle stretching device for sports training in order to solve the above-mentioned problem, thereby improving the problem that the user cannot clearly know the specific height of the pull ring required during adjustment, which causes the user to need to make repeated adjustments during adjustment, which is relatively cumbersome.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a muscle stretching device for sports training, comprising: a base, both sides of the top of the base are fixedly connected with spring telescopic rods, a cross bar is fixedly connected between the opposite sides of the two spring telescopic rods, a long plate is fixedly connected to the middle part of the top of the base, and an adjustment mechanism is arranged at the bottom end of the cross bar; wherein, the adjustment mechanism comprises a threaded rod rotatably connected to the bottom end of the cross bar, a moving frame is threadedly connected to the surface of the threaded rod, two round rods are fixedly connected to the bottom end of the cross bar, the inner wall of the moving frame is slidably connected to the surface of the round rod, the inner wall of the moving frame is slidably connected to a moving plate, the bottom end of the moving plate passes through the moving frame and is fixedly connected with two pull ropes, the bottom end of the pull rope is fixedly connected with a pull ring, and a locking component is arranged inside the moving frame.

[0008] Preferably, the locking assembly includes two sliders slidably connected to the bottom wall of the moving frame, one side of the slider is hinged with a connecting rod, the other end of the connecting rod is hinged with the bottom end of the moving plate, the other side of the slider is fixedly connected with a clamping rod, and the surface of the round rod is provided with equidistantly distributed clamping holes. When the pull ring is pulled to move downward, under the action of the moving plate and the connecting rod, the clamping rod enters the clamping hole and clamps with the clamping hole, completing the fixing of the moving plate, the moving frame and the round rod, which is conducive to the pull ring driving the moving plate to move downward and driving the round rod to move downward synchronously, which is conducive to increasing the stability when the pull ring pulls the cross bar to move downward, thereby improving the stability of the device during operation.

[0009] Preferably, the top of the movable plate is fixedly connected with a first spring, and the top of the first spring is fixedly connected with the top of the movable frame. Under the action of the first spring, when the user releases the pull ring, the clamping rod and the clamping hole are automatically released, which is conducive to the user not having to manually touch when adjusting the height of the pull ring, and the operation is more convenient.

[0010] Preferably, the inner bottom wall of the movable frame is provided with two slide grooves, and the surface of the slider is slidably connected to the inner wall of the slide groove, which is conducive to limiting the movement of the slider and ensuring the stability of the clamping rod when entering the clamping hole.

[0011] Preferably, the main body of the clamping rod is cylindrical, and the end of the clamping rod is hemispherical, thereby reducing the friction force when the clamping rod enters the clamping hole.

[0012] Preferably, the shape of the clamping hole matches that of the clamping rod, and the opening of the clamping hole is trumpet-shaped, which is conducive to better entry of the clamping rod into the clamping hole and ensures the stability of the clamping rod when clamping with the clamping hole.

[0013] Preferably, the lower end of the surface of the threaded rod is provided with grooves distributed at equal intervals, which is beneficial to increase the friction force when the user rotates the threaded rod, and is more labor-saving.

[0014] Preferably, the bottom end of the round rod is bent into a hemispherical shape to avoid accidental injury to the user.

[0015] The beneficial effects of the utility model are:

[0016] 1. The setting of the adjustment mechanism. When the height of the pull ring needs to be adjusted, the user only needs to lie on the long board and rotate the threaded rod to make the movable frame rise and fall, thereby adjusting the height of the pull ring. This is conducive to completing the height adjustment at one time, avoiding multiple adjustments, and the operation is more convenient;

[0017] 2. When the pull ring is pulled to move downward, under the action of the movable plate and the connecting rod, the clamping rod enters the clamping hole and clamps with the clamping hole to complete the fixation of the movable plate, the movable frame and the round rod, which is conducive to the pull ring driving the movable plate to move downward and the round rod to move downward synchronously, which is conducive to increasing the stability of the pull ring when pulling the cross bar to move downward, thereby improving the stability of the device during operation.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-4As shown, a muscle stretching device for sports training comprises: a base 1, spring telescopic rods 2 are fixedly connected to both sides of the top of the base 1, a cross bar 3 is fixedly connected between the opposite sides of the two spring telescopic rods 2, a long board 4 is fixedly connected to the middle of the top of the base 1, and an adjustment mechanism 5 is arranged at the bottom end of the cross bar 3; wherein, the adjustment mechanism 5 comprises a threaded rod 501 rotatably connected to the bottom end of the cross bar 3, a moving frame 503 is threadedly connected to the surface of the threaded rod 501, two round rods 502 are fixedly connected to the bottom end of the cross bar 3, the inner wall of the moving frame 503 is slidably connected to the surface of the round rod 502, a moving plate 504 is slidably connected to the inner wall of the moving frame 503, the bottom end of the moving plate 504 passes through the moving frame 503 and is fixedly connected to two pull ropes 505, the bottom end of the pull rope 505 is fixedly connected to a pull ring 506, and a locking assembly 507 is arranged inside the moving frame 503.

[0025] The spring telescopic rod 2 includes a support rod and a telescopic sleeve. The bottom end of the support rod is fixedly connected to the top of the base 1, one side of the telescopic sleeve is fixedly connected to the cross bar 3, the inner wall of the telescopic sleeve is slidably connected to the surface of the support rod, the inner top wall of the telescopic sleeve is fixedly connected with a spring, and the bottom end of the spring is fixedly connected to the top of the support rod.

[0026] When the device needs to be used for muscle stretching exercises, the user lies on the long board 4, raises one of the arms and makes it perpendicular to the body. At this time, the height of the pull ring 506 is adjusted according to the distance between the pull ring 506 and the hand. During adjustment, the user's other hand rotates the threaded rod 501. When the threaded rod 501 rotates, it drives the moving frame 503 to move, thereby driving the moving plate 504, the pull rope 505 and the pull ring 506 to move synchronously. When one of the user's palms holds the pull ring 506 at the right height, the threaded rod 501 is stopped from rotating. At this time, the user's two palms hold the corresponding pull ring 506 at the same time and pull the pull ring 506 downward. At this time, the locking assembly 507 is driven to operate.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the locking assembly 507 includes two sliders 5072 slidably connected to the inner bottom wall of the moving frame 503, one side of the slider 5072 is hinged with a connecting rod 5071, the other end of the connecting rod 5071 is hinged with the bottom end of the moving plate 504, the other side of the slider 5072 is fixedly connected with a clamping rod 5073, and the surface of the round rod 502 is provided with equidistantly distributed clamping holes 5074. The inner bottom wall of the moving frame 503 is provided with two chute 5076, and the surface of the slider 5072 is slidably connected with the inner wall of the chute 5076. The overall shape of the clamping rod 5073 is cylindrical, and the end of the clamping rod 5073 is hemispherical. The lower end of the surface of the threaded rod 501 is provided with equidistantly distributed grooves. The bottom end of the round rod 502 is bent in a hemispherical shape.

[0028] When the user pulls the pull ring 506 to move downward, the movable plate 504 is driven downward by the action of the pull ring 506 and the pull rope 505. At this time, the locking assembly 507 is driven to operate. When the movable plate 504 moves downward, it will drive the other end of the connecting rod 5071 to move downward. At this time, one end of the connecting rod 5071 will push the slider 5072 to move toward the side close to the round rod 502, and the angle between the connecting rod 5071 and the horizontal plane will gradually become smaller. When the slider 5072 moves in the slide groove 5076, it will drive the connecting rod 5073 to move synchronously, and make the connecting rod 5073 enter the connecting hole 5074 and be connected with the connecting hole 5074. At this time, when the pull ring 506 drives the movable plate 504 to move downward, it will drive the movable frame 503 and the round rod 502 to move downward synchronously, and drive the cross bar 3 to move downward, so that the spring telescopic rod 2 will contract, thereby performing a stretching movement.

[0029] like Figure 3 As shown, the top of the moving plate 504 is fixedly connected with a first spring 5075, and the top of the first spring 5075 is fixedly connected with the top of the moving frame 503. When the moving plate 504 moves downward, the first spring 5075 will stretch, and when the user moves his arm upward to release the pull ring 506, the moving plate 504 will be reset under the action of the first spring 5075, and the clamping connection between the clamping rod 5073 and the clamping hole 5074 will be released. When the moving plate 504 is stretched downward again, the above operation will be repeated to complete the clamping connection again.

[0030] like Figure 4 As shown, the shape of the clamping hole 5074 matches the shape of the clamping rod 5073, and the opening of the clamping hole 5074 is horn-shaped. The distance between two adjacent clamping holes 5074 is small, ensuring that the clamping rod 5073 can enter the clamping hole 5074.

[0031] When the utility model is used, when the device is needed to perform muscle stretching exercises, the user lies on the long board 4, raises one of the arms and makes it vertical to the body. At this time, the height of the pull ring 506 is adjusted according to the distance between the pull ring 506 and the hand. During the adjustment, the user's other hand rotates the threaded rod 501 to drive the moving frame 503 to move, thereby driving the moving board 504, the pull rope 505 and the pull ring 506 to move synchronously. When one of the user's palms simultaneously holds the pull ring 506 at the right height, the threaded rod 501 is stopped from rotating. At this time, the two palms of the user are simultaneously Hold the corresponding pull ring 506 and pull the pull ring 506 downward. Under the action of the pull ring 506 and the pull rope 505, the movable plate 504 is driven to move downward, so that the other end of the connecting rod 5071 pushes the slider 5072 and the clamping rod 5073 to move toward the side close to the round rod 502, and the clamping rod 5073 enters the clamping hole 5074 and is clamped with the clamping hole 5074. At this time, when the pull ring 506 drives the movable plate 504 to move downward, it will drive the movable frame 503 and the round rod 502 to move downward synchronously, and drive the cross bar 3 to move downward, so that the spring telescopic rod 2 will contract, thereby performing a stretching movement.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
