Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a fitness equipment extension arm structure that combines stability and smoothness. Background Technology

[0002] Multi-gym trainers are a common type of fitness equipment that uses different machines to perform various strength training exercises. However, existing multi-gym pulley extension arms cannot simultaneously achieve stability and smoothness. Therefore, it is necessary to ensure the stability and smoothness of the extension arms to guarantee the user's experience and safety during exercise. Most products on the market currently use double bushings or double rollers to achieve stability of the extension arms. However, when the product has a double bushing structure, the up and down adjustment of the extension arms is not smooth enough, and the double roller structure makes it difficult to guarantee the stability of the extension arms. Therefore, it is necessary to design a fitness equipment extension arm structure that can satisfy both stability and smoothness. Utility Model Content

[0003] The purpose of this invention is to provide a fitness device extension arm structure that combines stability and smoothness.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fitness equipment extension arm structure that combines stability and smoothness includes a vertical tube, a movable mechanism, and an extension arm. The extension arm is mounted on the movable mechanism and is movably mounted on the vertical tube through the movable mechanism.

[0006] The movable mechanism includes a movable seat, a pulley, and a bushing. The movable seat is movably mounted on the vertical tube, the extension arm is fixedly mounted on the movable seat, the pulley is disposed inside the movable seat and rolls along the vertical tube, and the bushing is disposed inside the movable seat and cooperates with the vertical tube.

[0007] Furthermore, the side wall of the vertical tube is provided with multiple pin holes, the movable seat is provided with a insertion hole, and a pin is movably installed inside. The pin can be pushed or pulled or controlled by the handle connected to the pin to exit or enter the pin hole, thereby restricting the movement of the movable seat.

[0008] Furthermore, the movable seat has a U-shaped structure, and a fixing plate is installed at the opening by screws. The fixing plate and the opening form a groove-shaped structure, and the extension arm is set in the groove-shaped structure and connected and fixed to the movable seat by screws.

[0009] Furthermore, the outer wall of the movable seat is provided with a lever for manual pulling.

[0010] Furthermore, there are two bushings, one on the vertical tube on the same side of the extension arm and the other on the vertical tube on the other side. There are two pulleys, one below the extension arm and the other above the extension arm.

[0011] Furthermore, the movable seat is provided with multiple rotating holes and screw holes. The pulley is rotatably mounted in the rotating hole via a rotating shaft, and the bushing is installed in the screw hole with screws to fix it in the movable seat.

[0012] Furthermore, the bushing has a C-shaped structure, and its opening is adapted to fit the vertical pipe.

[0013] Furthermore, the two bushings are arranged diagonally, and the two pulleys are arranged diagonally.

[0014] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0015] This utility model connects the movable mechanism to the extension arm, which drives the arm to move along the vertical tube. The movable mechanism has a built-in pulley and bushing. The pulley improves the smoothness of the movement, and the bushing enhances the stability of the movable mechanism and the extension arm. The combination of the two achieves a fitness equipment extension arm structure that combines stability and smoothness. Attached Figure Description

[0024] Example

[0025] Cooperate Figures 1 to 4 As shown, this utility model discloses a fitness equipment extension arm structure that combines stability and smoothness, including a vertical tube 1, a movable mechanism 2, and an extension arm 3. The extension arm 3 is mounted on the movable mechanism 2 and is movably mounted on the vertical tube 1 through the movable mechanism 2. In this embodiment, the vertical tube 1 is set on the fitness equipment in a conventional fixed manner, and this example is not limited to this.

[0026] The movable mechanism 2 includes a movable seat 21, a pulley 22, and a bushing 23. The movable seat 21 is movably mounted on the vertical tube 1, the extension arm 3 is fixedly mounted on the movable seat 21, the pulley 22 is disposed inside the movable seat 21 and rolls along the vertical tube 1, and the bushing 23 is disposed inside the movable seat 21 and cooperates with the vertical tube 1.

[0027] In this embodiment, the movable mechanism 2 is connected to the extension arm 3, which drives the extension arm 3 to move along the vertical tube 1. The movable mechanism 2 has a pulley 22 and a bushing 23. The pulley 22 can improve the smoothness of its movement, and the bushing 23 can improve the stability of the movable mechanism 2 and the extension arm 3. The combination of the two realizes a fitness equipment extension arm 3 structure that has both stability and smoothness.

[0028] The vertical tube 1 has multiple pin holes 11 on its side wall, and the movable seat 21 has a plug hole. The plug hole and the pin hole are set on the same side, and a pin 24 is movably installed inside. The pin 24 can be pushed or pulled or controlled by the handle connected to the pin 24 to exit or enter the pin hole 11, thereby restricting the movement of the movable seat 21.

[0029] The movable seat 21 is provided with a pin seat, which contains a return spring. The return spring cooperates with the pin or handle by being sleeved on its outer wall and having a corresponding limiting structure. This is existing technology and is not limited in this embodiment. The pin is pushed into the pin hole 11.

[0030] The movable seat 21 has a U-shaped structure, and a fixing plate 25 is installed at the opening by screws. The fixing plate 25 and the opening form a groove structure. The extension arm 3 is set in the groove structure and is connected and fixed to the movable seat 21 by screws.

[0031] The movable seat 21 can be a one-piece molded U-shaped plate, or it can be a structure composed of three plates connected by welding or screws.

[0032] The outer wall of the movable seat 21 is provided with a pull rod 26 for manual pulling, and the pull rod 26 is fixed to the movable seat 21 by screws or welding.

[0033] Two bushings 23 are provided, one on the vertical tube 1 on the same side as the extension arm 3 and the other on the vertical tube 1 on the other side. Two pulleys 22 are provided, one below the extension arm 3 and the other above the extension arm 3.

[0034] In this embodiment, the two bushings and the two pulleys are arranged diagonally.

[0035] The movable seat 21 is provided with multiple rotating holes and screw holes. The pulley 22 is rotatably installed in the rotating hole via a rotating shaft. The bushing 23 is installed in the screw hole with screws and is fixed inside the movable seat 21.

[0036] The bushing 23 has a C-shaped structure, and its opening is adapted to the vertical tube 1. The bushing 23 can also be fixed to the fixing plate with screws to increase its stability. In use, the two bushings 23, together with the movable seat 21, can provide support to the extension arm 3 to prevent it from tilting or breaking.

[0037] The connection method in this embodiment is through screw connection, and its structure must have corresponding screw holes.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
