Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, specifically a sliding connection module and a fitness machine. Background Technology

[0002] In the fitness equipment industry, fitness racks, as a type of multifunctional fitness device, are widely used in home fitness and gyms due to their advantages such as adaptability to various fitness movements and high customizability. The core structure of a fitness rack typically consists of multiple support rods assembled into a main support structure. By mounting different functional components on these support rods, various fitness functions can be achieved. The connection structure between the functional components and the support rods directly determines the fitness rack's functional expandability, flexibility of use, and ease of assembly, and is one of the key factors affecting the competitiveness of fitness rack products.

[0003] Currently, the connection methods between functional components and support rods in fitness racks are mainly divided into two categories: fixed connections and simple sliding connections. Fixed connections often employ bolt fastening, welding, or one-piece molding. While these structures ensure connection stability, they have significant drawbacks: First, the positions of functional components are fixed, making it impossible to adjust their height or horizontal position according to the user's height and exercise needs, resulting in poor adaptability. Second, when replacing functional components or storing / transporting the fitness rack, fixed connections are difficult to disassemble, often requiring multiple people and specialized tools, making the process cumbersome and inefficient, increasing user costs and storage / transportation difficulties.

[0004] To address the lack of flexibility in fixed connections, some fitness racks have adopted a simple sliding connection structure. This involves directly fitting functional components or connecting parts onto the outside of the support rod, achieving sliding through a clearance fit. To ensure sliding stability and locking effect, existing sliding connection structures are typically designed as a single unit. Disassembly requires removing other parts of the fitness rack first, making it difficult for a single person to complete. Furthermore, repeated disassembly can lead to increased clearance and loosening of the connection, reducing the product's lifespan. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please see Figures 1-5 This application provides the following technical solutions: The sliding connection module is used in the connection structure of fitness equipment, such as the connection between the support rod and some fitness components. For ease of explanation, the two vertical mid-surfaces and one horizontal mid-surface of the sliding connection module itself are used as reference surfaces. The two vertical mid-surfaces are reference surface A and reference surface B, which are perpendicular to each other; the horizontal mid-surface is reference surface C; Figure 3 With the direction as the reference, and reference plane A as the perpendicular tangent, Figure 3 The main module is divided into two halves, left and right. Reference plane B is based on... Figure 4 Using direction as a reference, Figure 4 The middle module is divided into two halves, left and right. For reference plane C, then regardless of... Figure 3 still Figure 4 Both will divide this module into two halves, upper and lower.

[0024] The sliding connection module of this solution includes a first connecting component 1 and a second connecting component 2. Two sets of first connecting components 1 are symmetrically arranged, with reference plane A as a mirror image. Each first connecting component 1 has four first connecting structure combinations 12 arranged on both sides relative to reference plane B, two on each side. The two first connecting structure combinations 12 on the same side are vertically distributed, located above and below their corresponding first connecting component 1. The two first connecting structure combinations 12 on the same side are arranged in a mirror-symmetrical structure with reference plane C as the midpoint.

[0025] The second connecting component 2 is symmetrically arranged in four groups with reference plane B as the mirror plane. Each second connecting component 2 includes two second connecting structure combinations that correspond to the first connecting structure combination 12. The two second connecting structure combinations are symmetrical with reference plane A as the mirror plane.

[0026] The two first connecting components 1 form an integral structure through the second connecting components 2 on both sides; the first connecting components 1 and the second connecting components 2 are detachably connected to the second connecting structure assembly through the first connecting structure assembly 12; a connection space is left between the two first connecting components 1 for sliding connection with the external support structure.

[0027] like Figure 1 and Figure 2 As shown, the sliding connection module of this solution is approximately a rectangular frame. It is composed of two first connecting components 1 and four second connecting components 2, and all connections are detachable.

[0040] The second connector A21 has several through-holes A and B, forming a second connecting structure assembly. Connecting holes A are circular, and connecting holes B are rectangular. Connecting holes A are detachably connected to the first connecting structure A121 and the first connector A111, which is located at the aforementioned roller shaft position of the rotating roller 13. The second connector A21 is hooked to the first connector B112 via connecting holes B.

[0041] The second connector B22 is located on the opposite side of the two second connecting components 2. The second connector B22 is detachably connected to the second connector A21 by bolts. The second connector B22 also has a rectangular through hole, which corresponds to the hook part of the first connector B112. The hook part of the first connector B112 is located in the through hole of the second connector A21, which can be inserted into the second connector B22, but does not protrude.

[0042] The second connector C23 is located on the side of the second connector A21 opposite to the second connector B22. The second connector C23 is detachably connected to the second connector A21. The second connector C23 is provided with an arc-shaped notch. The notch of the second connector C23 is oriented away from the other second connector C23 on the same side.
