[0002] A leg trainer and extension device is a piece of fitness equipment used to exercise the thigh, calf and buttocks muscles. This device is usually designed as an adjustable seat with one or more rollers or cushions for supporting the feet and performing stretching exercises. By using this device, people can perform leg stretching exercises to enhance muscle flexibility, strength and endurance. Leg trainer and extension devices are common in gyms and home fitness, and are the choice of many people for leg training and rehabilitation exercises.

[0003] The existing patent (publication number: CN209933966U) proposes a seated leg-pressing training device. This utility model achieves the effect of supporting the seat and the pedaling mechanism by setting a base. Through the first threaded rod and the first threaded tube, the first connecting plate and the seat are driven to move, and the position of the seat can be adjusted. Through the first bevel gear and the second bevel gear, the second threaded rod is driven to rotate. Through the second threaded rod and the second threaded tube, the training device can adjust the height and position of the seat, making it convenient for people to use.

[0004] However, the existing leg trainer stretching device has no protective device. During the stretching process, if the user cannot control the speed of the movement or cannot return to the original position slowly due to muscle exhaustion, the device will fall back quickly, increasing the risk of injury. Appropriate protective devices can help users perform more stable training, but the lack of such devices may cause users to be afraid to go all out for safety reasons, thereby reducing the intensity and effect of training. The stretching device without a buffer will cause additional impact and wear on the mechanical structure when it falls back quickly, thereby reducing the service life of the device. Therefore, the utility model proposes a leg trainer stretching device to solve the above problems. Utility Model Content

[0032] 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.

[0033] like Figures 1-4 As shown, this embodiment provides a technical solution: a leg training and stretching device, comprising a base 1, a support frame 2 fixed on the base 1, a first slide bar 3 fixed on the support frame 2, a leg kicking assembly 4 provided on the first slide bar 3, a seat assembly 5 provided on one side of the base 1, and a protective assembly 6 provided on the support frame 2;

[0034] like Figure 1 As shown, the leg kick assembly 4 includes a first slider 41, a bracket 42 is fixed to the first slider 41, a limit rod 43 is fixed to the first slider 41, a sheet loading rod 44 is fixed to the bracket 42, a leg kick plate 45 is fixed to the bracket 42, an anti-sliding plate 46 is provided on the leg kick plate 45, and a limit block 47 is fixed to the first slider 41. The seat assembly 5 includes a bottom plate 51, a seat body 52 is rotatably connected to the bottom plate 51, and a fixing block 53 is provided on the bottom plate 51;

[0035] like Figure 1-Figure 3As shown, the protective component 6 includes a connecting column 61, a hollow tube 62 is fixed on the connecting column 61, an exhaust hole 63 is opened on the hollow tube 62, a telescopic spring 64 is fixedly connected in the hollow tube 62, the other end of the telescopic spring 64 is fixedly connected to a second slider 65, a second slide bar 66 is fixed on the second slider 65, and a rubber block 67 is fixed on the end of the second slide bar 66 away from the second slider 65. In fitness training, especially for lower limb strength training, safety and efficiency are the issues that users are most concerned about. The design of this device fully takes these two aspects into consideration and provides a leg-pressing training equipment that can effectively exercise leg muscles and provide protection when the user is exhausted. First, through the easily adjustable plate loading rod 44, the user can easily add or remove barbell plates according to his or her own strength level and training needs to achieve a suitable training intensity. The angle adjustment function of the seat body 52 allows the user to find a most comfortable sitting posture, which helps to ensure The user maintains the correct posture, thereby reducing the risk of injury and improving the training effect. The anti-slider 46 design on the leg kick plate 45 ensures the stability of the foot, allowing the user to concentrate on the leg kicking action without worrying about the foot slipping. When performing the leg kicking exercise, the first slide bar 3 provides a stable track for the leg kicking component 4, making the leg movement smoother and more concentrated. When the user's legs are exhausted after high-intensity training and cannot control the speed of the leg kicking component 4, the combined effect of the telescopic spring 64, the second slide bar 65 and the second slide bar 66 becomes particularly important. They together constitute a buffer system, which can provide appropriate resistance when the leg kicking component 4 falls rapidly, slowing down its descent speed, thereby avoiding impact injuries caused by sudden falls. This buffer mechanism not only protects the user's legs from unnecessary pressure, but also makes the entire training process safer and more controllable, thereby solving the technical problem of protecting the user's legs after the user's legs are exhausted.

[0036] The above solution still has the problem that the leg kicking assembly 4 cannot be quickly fixed when the user's legs feel uncomfortable. Figure 1-Figure 2 As shown, the first slider 41 is slidably connected to the first slide bar 3, and the bottom plate 51 is fixed to the base 1. Since the first slider 41 is slidably connected to the first slide bar 3, the first slide bar 3 acts as a limit movement for the first slider 41. Since the bottom plate 51 is fixed to the base 1, the seat assembly 5 will not move when the user is exercising their legs, and the leg training will not be affected.

[0037] like Figure 1 As shown, one end of the fixing block 53 is fixed to the base plate 51, and the other end of the fixing block 53 is clamped on the seat body 52. Since one end of the fixing block 53 is fixed to the base plate 51 and the other end of the fixing block 53 is clamped on the seat body 52, the angle of the seat body 52 can be adjusted on the base plate 51 to meet the needs of users of different body shapes.

[0038] like Figure 1-Figure 2 As shown, the connecting column 61 is fixed to the support frame 2, and the limit block 47 is connected to the rubber block 67. Since the connecting column 61 is fixed to the support frame 2, the protective assembly 6 can be supported and fixed on the support frame 2 as a whole. Since the limit block 47 is connected to the rubber block 67, the protective assembly 6 can play a buffering role for the entire kicking assembly 4;

[0039] like Figure 1 as well as Figure 4 When the locking yoke 72 is in the locked state, the locking yoke 72 is locked and the locking yoke 73 is locked, so that the locking yoke 72 can be locked in the locked state.

[0040] Working principle:

[0041] like Figures 1-4As shown, first of all, through the easily adjustable plate loading rod 44, the user can conveniently add or remove barbell plates according to his or her own strength level and training needs to achieve the appropriate training intensity. The angle adjustment function of the seat body 52 allows the user to find the most comfortable sitting posture, which helps to maintain the correct posture, thereby reducing the risk of injury and improving the training effect. The anti-slider 46 design on the leg kick board 45 ensures the stability of the feet, allowing the user to concentrate on the leg kicking action without worrying about the feet slipping. When performing leg kicking exercises, the user kicks the leg kick board 45 with both legs, and the leg kick board 45 drives the bracket 42 and the first slider 41 to move upward along the direction of the first slider 3, and cooperates with the weight of the barbell plates on the plate loading rod 44 to achieve training of the user's legs. When the user's legs are exhausted after high-intensity training and cannot control the speed of the leg kicking assembly 4, the telescopic spring 64, the second slider 65 and the first slider 41 are used to adjust the speed of the leg kicking assembly 4. The combined effect of the two slide bars 66 is particularly important. They together constitute a buffer system that can provide appropriate resistance when the leg kick assembly 4 falls rapidly, slowing down its falling speed, thereby avoiding impact injuries caused by sudden falls. This buffer mechanism not only protects the user's legs from unnecessary pressure, but also makes the entire training process safer and more controllable. When the user experiences leg discomfort or exhaustion and is unable to continue exercising during training, he or she can immediately stop the leg kicking action and grab the rotating handle 74. Then, through a quick and simple rotation action, the rotating rod 72 and the limit column 73 fixed thereon can be driven. The limit column 73 is designed to cooperate with the limit rod 43 in the device. When the rotating handle 74 is twisted, the limit column 73 will apply pressure to the limit rod 43, thereby locking the leg kick assembly 4 in the current position, allowing the user to respond quickly when leg discomfort or other emergency situations are discovered.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
