Description

Technical Field

[0001] The utility model relates to a novel foldable structure and its application in a fitness bike. Background Art

[0002] In the prior art, a folding structure is required for many products to reduce the occupied space or for other needs. For example, for the watch tube structure on a fitness bike, its existing structure is as Figure 1 shown, including a upper watch tube A, a watch tube fixing tube B and a screw group D that cooperate with each other. The end of the watch tube fixing tube forms a reduced tube C, with holes punched in the reduced tube. Holes are also punched in the watch tube at positions corresponding to the holes in the reduced tube. After the watch tube is sleeved into the reduced tube, it is fixed by the screw group D.

[0003] The disadvantages of the above structure are as follows:

[0004] 1. Since the end of the watch tube fixing tube adopts a multi-process method of punching after reducing the tube, it will cause difficult assembly.

[0005] 2. Due to the limitations of the reducing tube equipment and the pipe material, the linearity of the reduced tube is affected, and the upper watch tube will be skewed after assembly.

[0006] 3. The nested assembly structure of the upper and lower watch tubes makes the watch tube assembly unable to be folded, occupying a large area and wasting space. Content of the Utility Model

[0007] The purpose of the utility model is to solve the above problems of the prior art, and provide a novel foldable structure with simple structure, firm installation and small occupied space.

[0016] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail below through specific embodiments.

[0017] As Figure 2-3 shown, a new foldable structure includes a mutually cooperating upper body 1, a lower body 2, a folding assembly 3 and a positioning assembly 4. Among them, the folding assembly 3 includes: a hinge seat 31 is provided at the bottom of the upper body 1, a hinge shaft 32 is provided at the top of the lower body 2, the hinge seat 31 and the hinge shaft 32 are connected by a bolt assembly 33, and the upper body 1 and the lower body 3 are folded through the folding assembly 3. The positioning assembly 4 includes: a first connecting plate 41 is provided at the bottom of the upper body 1, and a second connecting plate 42 is provided at the top of the lower body 2 at the position cooperating with the first connecting plate. The first connecting plate 41 and the second connecting plate 42 are connected and fixed by a screw assembly 43.

[0018] Further, the hinge seat 31 is a U-shaped folding plate with openings 311 on both sides. The hinge shaft 32 is a shaft cylinder, and both ends of the U-shaped folding plate are clamped on both sides of the shaft cylinder. The bolt assembly 33 includes a bolt 331, a flat washer 332, a spring washer 333, and a nut 334. The bolt 331 and the flat washer 332 pass through the opening 311 and the shaft cylinder (hinge shaft 32) from one side, and the spring washer 333 and the nut 334 are locked from the other side. Further, positioning holes 411 and 421 are formed at the peripheries of the first connecting plate 41 and the second connecting plate 42. The positioning assembly 43 is a screw 431 and a spring washer 432. The screw 431 and the spring washer 432 are locked in the positioning holes 411 and 421 to connect and fix the first connecting plate 41 and the second connecting plate 42.

[0019] In a specific practical example, the present utility model can be used in products that need to be folded and fixed. Taking the watch tube assembly of a fitness bike as an example, the upper body 1 is the upper watch tube, and the lower body 2 is the watch tube fixing tube; the first connecting plate 41 and the hinge seat 31 are plate bodies of an integral structure fixed to the bottom of the upper watch tube, with the edge extending out of the upper watch tube. The front end of the plate body bends to both sides to form the hinge seat 31; a first positioning hole 411 is formed at the outer edge of the rear end. The second connecting plate 32 is adapted to the first connecting plate 31, with the edge extending out of the watch tube fixing tube, the front end protruding outside the watch tube fixing tube, and a second positioning hole 421 is formed at the outer edge of the rear end. The hinge shaft 32 is fixed below the protruding part at the front end; the first connecting plate 41 and the second connecting plate 42 are butted, and both ends of the hinge seat 31 pass through the protruding part and extend to both sides of the hinge shaft 32.
