Description
Technical Field
[0001] The utility model relates to the technical field of pipe fittings, in particular to a pipe for fitness equipment. Background Art
[0002] Fitness equipment is often divided into two categories according to the number of training functions: single-function and comprehensive multi-function. Commonly used ones include rowing machines, fitness bikes, steppers, treadmills, waist beautification machines, etc. Pipes are used in the manufacturing of equipment. This pipe fitting is used to manufacture fitness equipment.
[0003] When fitness equipment is manufactured, pipe fittings are assembled and connected. Since fitness equipment requires higher load-bearing performance, ordinary pipe fittings have poor load-bearing performance. The entire pipe fitting is an integrated structure. If materials with higher load-bearing performance are used, the cost will be higher. Utility Model Content
[0004] The utility model aims to provide a tube for fitness equipment.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A tube for fitness equipment comprises a middle tube, a tube cavity is opened in the middle of the middle tube, an inner core is installed on the inner side of the tube cavity, core recesses are opened on the upper and lower end walls of the inner core, end tubes are installed on the upper and lower ends of the middle tube, vertical holes are penetrated through the end walls of the end tubes, side holes are penetrated through the front end walls of the end tubes, and fixed holes are opened on the upper and lower end walls of the middle tube.
[0007] Preferably, the middle tube is threadably connected to the inner core through a tube cavity.
[0008] Preferably, the middle tube, the tube cavity and the inner core are all circular in shape.
[0009] Preferably, the core recesses are distributed in a ring shape about the center of the inner core.
[0010] Preferably, the middle tube and the end tubes are fixedly connected.
[0011] Preferably, the fixed holes are distributed in a ring shape about the center of the middle tube.
[0012] The utility model has at least the following beneficial effects:
[0013] 1. The Q steel inner core improves the bearing performance of the entire pipe fitting. When in use, screw the inner core into the lumen of the middle pipe, so that the inner core and the middle pipe can cooperate with each other to bear the load. The design of the core notch facilitates the rotation and driving of the inner core.
[0014] 2. The hexagonal end wall of the end pipe is more flexible and convenient during assembly and use. The vertical holes and side holes of the end wall of the end pipe are used to pass through the screw connectors for assembly and use. The fixed holes are also used to pass through the screw connectors for installing and using pipe fittings. BRIEF DESCRIPTION OF THE DRAWINGS
