Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a leg clamping machine. Background Technology

[0002] The leg clamp is a fitness device used to train the strength and endurance of the lower limbs, especially the leg muscles. Leg clamps are typically used to train the thigh muscles, including the quadriceps, gluteus maximus, and hamstrings. For example, a leg clamp disclosed in Chinese Utility Model Patent No. CN222566737U includes two curved arms, a torsion assembly, and a support plate. The torsion assembly includes a coil spring or torsion spring sleeved on the first rotating shaft. Because it is frequently used, coil springs or torsion springs are prone to fatigue, which can easily lead to damage and significantly reduce their lifespan. Furthermore, the resistance from the coil spring or torsion spring is relatively low, resulting in poor training effectiveness. Therefore, improvements are necessary based on the current situation.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0036] Example 1: See Figure 1A leg clamping machine includes a base 1 and a support seat 2 disposed on the base 1. The support seat 2 is provided with a hydraulic cylinder-type resistance leg clamp 3 and a bearing part 4. When in use, the user sits on the bearing part 4 and can exercise the lower limbs using the hydraulic cylinder-type resistance leg clamp 3. This invention overcomes the shortcomings of the prior art, which relies on coil springs or torsion springs, resulting in reduced service life due to fatigue, and the problem of poor exercise effect due to low resistance. It is more conducive to meeting the user's needs.

[0037] Example 2: This can be explained based on Example 1, such as... Figure 1 , Figure 6 and Figure 7 As shown, the upper surface of the support base 2 is provided with a bearing section 4, which facilitates the user's sitting posture. The side surface of the support base 2 is provided with a hydraulic cylinder-type resistance leg clamp 3. This arrangement is reasonable, allowing the user to exercise their lower limbs while seated on the bearing section 4 using the hydraulic cylinder-type resistance leg clamp 3. Further explanation: the bearing section 4 is a stool.

[0038] Example 3: This can be described based on Example 1 or Example 2, such as... Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the hydraulic cylinder-type resistance leg clamp 3 includes a hydraulic cylinder resistance 31 and a fixed base 32 mounted on a support base 2. The hydraulic cylinder resistance 31 has symmetrically distributed support arms 33, each with a support plate 34. The hydraulic cylinder resistance 31 and the fixed base 32 are detachably connected, facilitating disassembly and installation and improving future maintenance. The symmetrically distributed support arms 33 reciprocate around the hydraulic cylinder resistance 31, thereby exercising the lower limbs. Specifically, the hydraulic cylinder resistance 31 has a housing 35 with a slot at one end. The fixed base 32 is inserted into the slot, and the fixed base 32 and the housing 35 are locked together by fasteners. In this embodiment, the slot and the fixed base 32 have a clearance fit, facilitating disassembly and installation. The fasteners are screws or bolts, further simplifying disassembly and installation.

[0039] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the hydraulic cylinder resistance device 31 includes a hydraulic cylinder body 411 and a device seat 312 mounted on the piston rod of the hydraulic cylinder body 311. The device seat 312 is equipped with symmetrically distributed racks 313. Each support arm 33 is equipped with a swing wheel 314, and the swing wheel 314 is equipped with an arc-shaped gear portion. The arc-shaped gear portion meshes with the rack 313, thus converting the linear motion of the rack 313 into an arc-shaped reciprocating swing motion through the interaction of the arc-shaped gear portion and the rack 313. Further explanation: the hydraulic cylinder body 311 uses a hydraulic cylinder or a damping cylinder. This is convenient to implement, eliminates the problem of reduced service life caused by the fatigue of coil springs or torsion springs, and provides better resistance during exercise, improving the exercise effect and better meeting the user's needs.

[0040] Among them, such as Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the base 1 is equipped with a positioning seat 11 for mounting the hydraulic cylinder resistance device 31. One end of the hydraulic cylinder resistance device 31 is inserted into the positioning seat 11, and the hydraulic cylinder resistance device 31 and the positioning seat 11 are connected by fasteners, which are screws or bolts, for easy disassembly and installation. In use, the hydraulic cylinder resistance device 31 can be mounted on the positioning seat 21 or the fixed seat 32 as needed, which facilitates the user's exercise and meets the needs of different users.

[0041] like Figure 2 and Figure 7 As shown, in this embodiment, the base 1 is an "I"-shaped frame, and the support 2 is a vertical pole. This structure is relatively simple and easy to implement.

[0042] Example 4: This can be described based on Example 1, Example 2, or Example 3, such as... Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the support base 2 and the base 1 are connected by a pivot 21. This allows the support base 2 to be rotated down for storage, reducing space occupied during transportation and packaging. A pin 22 is provided between the support base 2 and the base 1 to lock the support base 2 in place after rotation. This ensures the support base 2 is locked in place when standing upright, facilitating normal use. In use, the pin 22 can be removed to allow rotation, facilitating storage or standing. The pin 22 can then be inserted to secure the support base.

[0043] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, such as... Figure 7As shown, the base 1 is provided with a stable base plate 12, which not only increases the contact area, but also makes it easier to adhere to the placement surface, thus improving the stability and safety of use.

[0044] All standard parts used in this application can be purchased from the market, and the specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology, which will not be described in detail here.

[0045] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
