DETAILED DESCRIPTION

[0025] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0026] like Figures 1-7 As shown, this embodiment provides an angle adjustment assembly for fitness equipment, which is used to adjust the relative angle between the movable component 102 and the fixed component 101, and one end of the movable component 102 is hinged to the fixed component 101. The angle adjustment assembly is used to make the movable component 102 flip up and down at the hinge between it and the fixed component 101 to change the relative angle between the two, thereby meeting the different physical conditions and exercise intensity requirements of exercisers.

[0027] The angle adjustment assembly of this embodiment includes an outer shell 10, an inner cylinder 20, an intermediate seat 30, a latch 60, a pull cord 50, and a handle 40. The inner cylinder 20 is movably inserted into the outer shell 10, and the latch 60, which is operated by the pull cord 50, is used to achieve the extension and retraction of the inner cylinder 20 and the outer shell 10. Specifically:

[0028] The outer sleeve 10 of the embodiment serves as a component connected between the angle adjusting assembly and the fixed part 101, and provides guiding and supporting functions for the inner cylinder 20 and limits the position of the inner cylinder 20. The bottom end of the outer sleeve 10 is provided with a hinged end hinged with the fixed part 101, and in the application state, the bottom end of the outer sleeve 10 is hinged with the fixed part 101 and can rotate adaptively with the change of the angle of the movable part 102 to avoid motion interference. The outer sleeve 10 has a cavity inside and an opening on the upper side of the cavity. The inner cylinder 20 is movably inserted into the cavity, and the top end of the inner cylinder 20 extends upward from the opening on the upper side of the outer sleeve 10. Preferably, the cross-sectional outer contour shape of the outer sleeve 10 and the inner cylinder 20 is a racetrack type, but it is not limited to this shape type and can also be circular or the like. In order to stabilize the cooperation between the inner cylinder 20 and the outer sleeve 10, an inner sleeve is fitted and embedded between the inner cylinder 20 and the outer sleeve 10, which can also reduce the wear between the inner cylinder 20 and the outer sleeve 10 and improve the service life. In addition, a plurality of insertion holes 11 are axially spaced apart on the side wall of the outer sleeve 10, and the plurality of insertion holes 11 are connected in a line and parallel to the axial direction of the cavity of the outer sleeve 10, that is, the movement direction of the inner cylinder 20 extending up and down the outer sleeve 10 is parallel to the line of the insertion holes 11. In this way, after the up and down extension adjustment of the inner cylinder 20, the bolt 60 can be directed to the insertion hole 11 to complete the limiting action.

[0029] In the embodiment, the inner cylinder 20 also has a chamber, and the upper part of the chamber is open. The upper part and the chamber are used to pass the pull rope 50, so that the pull rope 50 can be connected to the bolt 60 from the handle 40 from the chamber of the inner cylinder 20 downward. The shape of the chamber is not limited. Since the angle adjusting assembly is located between the fixed part 101 and the movable part 102, when the angle between the movable part 102 and the fixed part 101 changes, the distance between the hinged end of the outer sleeve 10 and the connection between the movable part 102 and the inner cylinder 20 will also change adaptively, and the inclination angle of the outer sleeve 10 will also change adaptively. At this time, the inner cylinder 20 should also change the angle, otherwise it will cause motion interference and cannot complete the angle adjustment. Therefore, the top end of the inner cylinder 20 of the embodiment is rotatably installed on the intermediate seat 30 through the second hinge shaft 32, and the intermediate seat 30 is fixedly installed on the bottom of the movable part 102 in the application state.

[0030] In the embodiment, the handle 40 is used for directly operating by the user to drive the pull rope 50 to make the plug 60 extend and retract, so that the outer sleeve 10 and the inner cylinder 20 can be axially extended and retracted or kept relative positions. To drive the pull rope 50 to operate and facilitate the user to directly operate the handle 40, the handle 40 is rotatably installed on the side of the intermediate seat 30 away from the inner cylinder 20 through the first hinge shaft 31, and the first hinge shaft 31 is provided with a return member (not shown in the figure) for returning the handle 40 in the opposite direction. One end of the pull rope 50 is connected to the handle 40, and the other end passes through the inner cylinder 20 and is connected to the plug 60. In the embodiment, the return member is a torsion spring, one torsion arm of the torsion spring abuts against the bottom of the movable part 102, and the other torsion arm abuts against the handle 40. In this way, the handle 40 is pulled upward, the pulling force can overcome the action force of the torsion spring, the pull rope 50 is pulled outward and upward, and the insertion end of the plug 60 is away from the insertion hole 11. When the pulling force is removed, the handle 40 is returned downward by the return force of the torsion spring, and then the pull rope 50 is retracted and the plug 60 moves towards the insertion hole 11 under the action of the reset member (not shown in the figure) at the position of the plug 60.

[0031] In the embodiment, the inner cylinder 20 includes a cylinder body 21 and a guide seat 22 fixedly connected to the bottom end of the cylinder body 21. The guide seat 22 and the cylinder body 21 are fastened by screws. The plug 60 is slidably arranged on the guide seat 22 of the inner cylinder 20 in a direction perpendicular to the line on which the plurality of insertion holes 11 are located. The plug 60 and the inner cylinder 20 are provided with a reset member for resetting the plug 60 in the opposite direction. The reset member is a compression spring. The plug 60 has an insertion end inserted into the insertion hole 11 and a connection end connected to the pull rope 50. The connection end is provided with a T-shaped insertion hole. The end of the pull rope 50 is connected to an insertion column which is inserted into the T-shaped insertion hole.

[0032] If the pull rope 50 is directly pulled, the resistance will be large because the pull rope 50 moves up and down in the barrel body 21 while the sliding direction of the latch 60 is vertical. Therefore, the embodiment designs some guide components on the guide seat 22 to make the pull rope 50 flexibly turn and reduce the pulling force. Because the pull rope 50 is flexible and can be turned in any direction, the specific implementation is as follows: the guide seat 22 is provided with a fifth guide part 75, the fifth guide part 75 includes a fifth rolling body in contact with the pull rope 50 and providing a guide function, the pull rope 50 extends linearly in a fifth direction to the connecting end of the latch 60 through the fifth rolling body, and the included angle between the fifth direction and the sliding direction of the latch 60 is 0-15°. In order to further guide the pull rope 50, the guide seat 22 is further provided with a third guide part 73 and a fourth guide part 74, the fourth guide part 74 is located between the third guide part 73 and the fifth guide part 75, the third guide part 73 is provided with a third guide hole for the pull rope 50 to pass through, the fourth guide part 74 includes a fourth rolling body in contact with the pull rope 50 and providing a guide function, and the pull rope 50 extends linearly in the fifth direction to the connecting end of the latch 60 through the fourth rolling body and the fifth rolling body after passing through the third guide hole. The fourth rolling body and the fifth rolling body are respectively installed on the guide seat 22 through shafts.

[0033] In addition, the embodiment further installs a first guide part 71 and a second guide part 72 on the intermediate seat 30 to guide the pull rope 50, and the specific implementation is as follows: the first guide part 71 is fixedly installed on the side of the intermediate seat 30 close to the handle 40, the first guide part 71 includes a first rolling body in contact with the pull rope 50 and providing a guide function, and the first rolling body is located below the first hinged shaft 31; the second guide part 72 is further provided between the first guide part 71 and the top end of the inner barrel 20, the second guide part 72 is provided with a first guide hole for the pull rope 50 to pass through, and the pull rope 50 from the handle 40 passes through the first rolling body, the first guide hole, enters the cavity of the inner barrel 20, and is connected with the latch 60 after turning through the third guide hole, the fourth rolling body and the fifth rolling body.

[0034] The first rolling body, the fourth rolling body and the fifth rolling body can specifically adopt rubber wheels or steel wheels and are installed through shafts. In order to reduce the resistance, a ball bearing can be further embedded between the first rolling body, the fourth rolling body and the fifth rolling body and the shafts. The outer contour shape of the first rolling body, the fourth rolling body and the fifth rolling body is preferably a trapezoidal cylindrical body that is inclined and reduced from both ends to the middle and forms a rope passing annular groove at the middle position, so that the pull rope 50 is guided to the rope passing annular groove position in the middle.
