Description

Technical Field

[0001] The utility model relates to a treadmill, in particular to a folding and locking mechanism of a handrail upright pole and a treadmill of the treadmill. Background Art

[0002] A treadmill is usually composed of a running belt and a frame. When in use, the user runs on the running belt and sometimes needs to hold the handrail assembly on the frame to walk slowly. The frame of a treadmill with a traditional structure is usually not foldable, which takes up a large space. It is inconvenient to place when not in use and is also inconvenient to carry when moving. In order to solve the problem that the traditional treadmill is too large and inconvenient to store and transport, the existing treadmill will set the handrail assembly to a foldable structure to meet the user's transportation, movement or storage needs. The folding of the handrail of the treadmill is usually achieved by rotating the handrail uprights and the treadmill. Whether it is laid down when not in use or stood up when in use, a corresponding locking mechanism is required to lock the relative position of the two. However, the folding locking mechanism of the handrail uprights and the treadmill of the existing treadmills is mostly complex in structure, and the disassembly and assembly process is very cumbersome. Part of the disassembly and assembly may also require the use of additional tools, which is inconvenient to disassemble and assemble. Summary of the invention

[0006] The inner end of the first locking toothed ring is fixedly extended from the side of the treadmill and installed in the treadmill, the outer end of the first locking toothed ring has the locking groove, the outer end of the first locking toothed ring is extended and arranged outside the treadmill, the second locking toothed ring is fixedly arranged on the inner end of the handrail upright and arranged opposite to the first locking toothed ring, and the side of the second locking toothed ring opposite to the outer end of the first locking toothed ring is provided with the locking teeth.

[0007] The eccentric wrench assembly includes an eccentric wrench and a shaft, wherein the eccentric wrench is arranged at the outer end of the handrail upright, the first end of the shaft is hinged to the eccentric wrench, and the second end of the shaft passes through the handrail upright, the second locking toothed ring and the first locking toothed ring in sequence and is fixedly arranged in the treadmill; the eccentric wrench is rotated to make the distal end of the eccentric wheel of the eccentric wrench abut against the handrail upright to achieve meshing and locking of the first locking toothed ring and the second locking toothed ring. By rotating the eccentric wrench, the position of the eccentric cam on the eccentric wrench is controlled to achieve meshing, locking and loosening of the first locking toothed ring and the second locking toothed ring, which is convenient and fast to disassemble and assemble, and the structure is relatively simple.

[0008] The second end of the shaft rod is fixedly arranged in the treadmill through a locking nut, and the second end of the shaft rod has a threaded connection section matched with the locking nut, and the threaded connection section is threadedly connected with the locking nut. The structure is simple and the installation is stable.

[0009] The shaft is sleeved with a spring, and a limit ring is arranged inside the first locking toothed ring. The spring is located between the limit ring and the inner side of the handrail upright pole, and the first end of the spring is against the limit ring, and the other end of the spring extends into the second locking toothed ring and is against the inner side of the handrail upright pole; when meshing and locking, the spring is in a compressed state. The first locking toothed ring and the second locking toothed ring are quickly released through the resetting action of the spring.

[0010] The first locking toothed ring is provided with a first limiting sleeve, the second locking toothed ring is provided with a second limiting sleeve coaxial with the first limiting sleeve, the shaft rod is inserted into the first limiting sleeve and the second limiting sleeve, and the spring sleeve is provided outside the first limiting sleeve and the second limiting sleeve; when engaged and locked, the opposite end faces of the first limiting sleeve and the second limiting sleeve fit together. The cooperation between the first limiting sleeve and the second limiting sleeve plays a limiting role in the locking position.

[0011] The outer side protrusion of the treadmill is provided with a first limiting column, and the inner side protrusion of the handrail upright is provided with a second limiting column. When the first limiting column and the second limiting column are in contact, they are used to limit the extreme support position of the handrail upright when in use.

[0012] Compared with the prior art, the advantages of the utility model are: simple structure, when locking, the locking teeth on the second locking toothed ring are meshed and embedded in the locking groove of the first locking toothed ring, and the eccentric wrench assembly is used to achieve meshing and locking, so that the handrail upright and the treadmill can be folded or erected for use. When loosening and releasing is required, the locking state of the first locking toothed ring and the second locking toothed ring is released by operating the eccentric wrench assembly, so that the locking teeth are disengaged from the locking groove, and the relative positions of the two can be changed at this time. No additional disassembly tools are required during disassembly and assembly, and disassembly and assembly are convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
