There are many types of leg clamp trainers on the market, but most of them have complex structures and poor stability in use. In view of this, overcoming the defects of the above-mentioned existing technologies is a problem that needs to be urgently solved in this technical field. Utility Model Content

[0003] The utility model provides a leg clamping training device, aiming to improve the problems of most current training devices, such as relatively complex structures and poor stability in use.

[0004] To achieve the above purpose, the present invention provides a leg clamp training device, the specific technical solution of which is as follows:

[0005] A leg clamp training device comprises a main body, with leg support mechanisms provided on both sides of the main body, the main body comprising a base, a slider provided on the inner upper side of the base, the slider being capable of sliding up and down within the base, a connecting rod mechanism provided between the slider and the two leg support mechanisms, the leg support mechanism being capable of driving the slider to slide downward within the base via the connecting rod mechanism, the lower side of the slider abutting against a spring, the lower side of the spring abutting against the inner bottom end of the base;

[0006] During exercise, the two legs of the exerciser clamp the two leg support mechanisms inward, and the two leg support mechanisms drive the slider in the base to slide downward through the connecting rod mechanism, and then the slider squeezes the spring downward. The spring is compressed under the action of the slider and the base to store force. When the exerciser stops exerting force with his legs and no longer clamps the leg support mechanisms inward, the compressed spring stretches upward under the action of elastic force, and then the spring pushes the slider upward. The slider drives the two leg support mechanisms to move outward to the initial position through the connecting rod mechanism. The exerciser repeatedly clamps the legs in this way to achieve the purpose of exercise.

[0007] In one embodiment, the leg support mechanism includes a support arm, and a leg rest portion is provided on one side of the support arm, and the leg rest portion is used to rest against the leg of the exerciser.

[0008] In one embodiment, the connecting rod mechanism includes a rotating rod, which is arranged at an end of the support arm away from the leg support portion. One side of the rotating rod is rotatably mounted on the base, and the other side is rotatably mounted with a moving rod. The side of the moving rod away from the rotating rod is rotatably connected to the slider. The rotation of the rotating rod can drive the moving rod to move, and then the moving rod pushes the slider to slide in the base.

[0009] In one embodiment, the main body further includes a shell, the two leg support mechanisms are symmetrically arranged on both sides of the exterior of the shell, the shell includes a front shell and a rear shell, and the base is fixed in a cavity surrounded by the front shell and the rear shell.

When the screw is rotated, the screw can move up and down under the action of the base. When the screw moves upward, the screw pushes the adjustment seat upward, and then the adjustment seat squeezes the spring upward, the degree of compression of the spring increases, and then the stored force increases, and then the force required to be applied by the exerciser increases.

[0011] In one embodiment, a positioning pin is provided in the middle of the upper end of the adjustment seat, and the lower side of the spring is sleeved on the outer side of the positioning pin.

[0012] In one embodiment, a knob is fixed to the lower end of the screw rod, and the knob is arranged at the lower outer portion of the shell. Rotation of the knob can drive the screw rod to rotate.

[0013] In one embodiment, a force display mechanism is provided on one side of the force adjustment mechanism, and the force display mechanism includes a card joint, which is provided on one side of the adjustment seat, a rack is fixed on the card joint, and a gear is connected to one side of the rack for transmission, a connecting shaft is provided in the middle of the gear, the connecting shaft passes through the front shell, an indicator needle is fixed on the outside of the connecting shaft, the indicator needle is provided on the outside of the front shell, a numerical display disk is provided between the indicator needle and the gear, the numerical display disk is fixed on the outside of the front shell, and the connecting shaft crosses the center of the numerical display disk.

The exercise is repeated in this cycle to achieve the exercise of the leg muscle groups. The whole device has a simple structure, is easy to produce, has low manufacturing cost, and has good stability in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments 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.

[0039] The technical solutions provided by the embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0040] See also Figure 1 、 Figure 3 、 Figure 4 and Figure 6The leg support 220 is detachably mounted on the support arm 210, which makes the whole component easy to process and assemble. In addition, the leg support 220 is ergonomically designed and conforms to the shape of the human leg. When exercising, the legs rest on the leg support 220, which makes the fit high and the exercise more comfortable. Preferably, a layer of protective pad is provided on the outer surface of the leg support 220. The protective pad can be made of sponge, flexible plastic or the like, so that the legs of the exerciser rest on the leg support 220 and contact with the protective pad. The protective pad is relatively soft, so that when the exerciser clamps the leg support 220, the legs and the leg support 220 are flexibly combined, which makes the exerciser more comfortable.

[0041] See also Figure 1 、 Figure 4 、 Figure 6 and Figure 7 The main body 100 includes a shell 140. The two leg support mechanisms 200 are symmetrically arranged on both sides of the exterior of the shell 140 to facilitate the exerciser's two legs to perform clamping exercises. The shell 140 includes a front shell 141 and a rear shell 142. The front shell 141 and the rear shell 142 are fixed together by screws. A cavity is formed between the two. The base 110 is provided in the cavity. The base 110 and the front shell 141 and the rear shell 142 are fixed together. A mounting groove is provided in the middle of the base 110. The inner portion of the mounting groove is provided with a mounting groove. A slider 120 is provided on the side, and the slider 120 can slide up and down in the mounting groove of the base 110. A connecting rod mechanism 300 is provided between both sides of the slider 120 and the two leg support mechanisms 200. The leg support mechanism 200 can drive the slider 120 to slide downward in the mounting groove of the base 110 through the connecting rod mechanism 300. It should be noted that the lower end surface of the slider 120 abuts against a spring 130, and the spring 130 is also provided in the mounting groove of the base 110, and the lower end of the spring 130 abuts against the bottom end of the mounting groove of the base 110;

[0042] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 8The cam 320 is connected to the support frame 110 by the spring 321 and the spring 322 is connected to the support frame 110 by the spring 323.

[0043] When people exercise, the two legs of the exerciser rest on the leg support 220, and then the two legs exert force to clamp the two leg support mechanisms 200 inward at the same time. The two leg support mechanisms 200 drive the rotating rod 310 to rotate downward around the rotating axis. The rotating rod 310 drives the moving rod 320 to rotate and move downward at the same time, and then the moving rod 320 pushes the slider 120 downward, and then the slider 120 squeezes the spring 130 downward. The lower side of the spring 130 is blocked by the base 110 and cannot move downward, and then the spring 130 is compressed under the action of the slider 120 and the base 110 to realize force storage. When the exerciser's legs do not exert force and no longer clamp the leg support mechanisms 200 inward, the compressed spring 130 0 stretches upward under the action of elastic force, the spring 130 pushes the slider 120 upward, and the slider 120 pushes the moving rod 320 to move upward in the opposite direction, and then the moving rod 320 drives the rotating rod 310 to rotate upward, and then the rotating rod 310 drives the leg support mechanism 200 to move outward until it returns to the initial position. The exerciser repeatedly clamps the leg support mechanism 200 to achieve the purpose of exercise. The entire device has a simple structure, is easy to manufacture and assemble, has high assembly efficiency, and reduces processing costs. The leg support mechanism 200 drives the slider 120 through the connecting rod mechanism 300 to directly press the spring 130 downward. Through this structure, the force of the spring 130 can be compressed and released to a greater extent, thereby achieving a better exercise effect.

[0044] See also Figure 2 、 Figure 6 、 Figure 9 、 Figure 10 and Figure 13The spring 130 is preferably provided with a positioning pin 411 in the middle of the upper end of the adjusting seat 410, and the lower side of the spring 130 is sleeved on the outer side of the positioning pin 411 to prevent the spring 130 from moving left and right on the adjusting seat 410 and sliding down the adjusting seat 410, thereby playing a limiting role; a screw 420 is abutted on the lower side of the adjusting seat 410, and the screw 420 is screwed to the lower end of the base 110. Preferably, a nut is embedded in the lower end of the base 110, and the screw 420 is screwed to the nut instead of being directly screwed to the base 110, thereby improving the service life of the base 110. It should be noted that A knob 421 is fixed to the lower end of the screw 420. The knob 421 is arranged at the lower outer portion of the housing 140. Turning the knob 421 can drive the screw 420 to rotate, making it convenient for the exerciser to turn the screw 420 from the outside of the device, making the device easy to adjust and use, and providing the user with a pleasant user experience. When adjusting the force, the knob 421 is turned, and the knob 421 drives the screw 420 to rotate. Under the action of the base 110, the screw 420 can move up and down. When the screw 420 moves upward, the screw 420 pushes the adjustment seat 410 upward, and the adjustment seat 410 presses the spring 130 upward. The compression degree of the spring 130 increases, and the stored force increases. When the exerciser clamps the leg support mechanism 200 with the same amplitude, the clamping force required to be applied is greater than before the adjustment seat 410 is adjusted. Conversely, the clamping force required by the exerciser is reduced.

[0045] See also Figure 1 、 Figure 6 、 Figure 11 、 Figure 12 and Figure 13In addition, a force display mechanism 500 is provided on one side of the force adjustment mechanism 400. The force display mechanism 500 includes a card joint 510. The card joint 510 is integrally formed and provided on one side of the adjustment seat 410. A rack 520 is fixed to the card joint 510. The rack 520 is provided on the inner side of the front shell 141. The rack 520 can slide up and down inside the front shell 141. One side of the rack 520 is meshed and connected with a gear 530. A connecting shaft 540 is integrally formed in the middle of the gear 530. The connecting shaft 540 passes through the front shell 141 and extends to the outside. The outer side of the connecting shaft 540 An indicator needle 550 is fixed to the side of the housing 141. The indicator needle 550 is arranged on the outside of the front housing 141. A numerical display disk 560 is provided between the indicator needle 550 and the gear 530. The numerical display disk 560 is fixed in a receiving groove on the outside of the front housing 141. The indicator needle 550 fits in front of the numerical display disk 560. The connecting shaft 540 passes through the center of the numerical display disk 560. The numerical display disk 560 is marked with corresponding numbers indicating the corresponding force values. The numbers on the numbers gradually increase in a clockwise direction. Through the indication of the indicator needle 550, the exerciser can clearly know the clamping force required for the current exercise state.

[0046] See also Figure 1 、 Figure 2 and Figure 6 When the adjustment seat 410 moves upward, it drives the rack 520 to move upward through the clamping joint 510. The upward movement of the rack 520 drives the gear 530 to rotate clockwise, and then the gear 530 drives the indicator needle 550 to rotate clockwise through the connecting shaft 540. Then, the value indicated by the indicator needle 550 increases, indicating that the required clamping force increases, so that the exerciser can intuitively, clearly and quickly understand the required clamping force, which is convenient for force adjustment. Preferably, a protective cover 570 is provided on the outside of the numerical display disk 560 and the indicator needle 550. The protective cover 570 is clamped at the opening of the receiving groove of the front shell 141. The numerical display disk 560 and the indicator needle 550 are isolated in the receiving groove of the front shell 141 by the protective cover 570 to prevent them from being damaged by the outside. The protective cover 570 is transparent. The exerciser can directly see the value indicated by the indicator needle 550 through the transparent protective cover 570 from the outside, which is convenient for observation.
