[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0034] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0035] In the description of the present invention, it should be understood that the terms "upper" and "lower" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.
[0036] The purpose of the present application is to provide an adjustment mechanism that can avoid the problem of the adjustment mechanism rapidly falling when the latch is positioned and only the rounded corner is hooked.
[0037] To achieve the above objectives, the present invention provides the following technical solutions:
[0038] See also Figure 1 and Figure 2 This embodiment provides an adjustment mechanism, which includes an adjustment frame 100, a sliding frame 200 and a limiting component.
[0039] The adjustment frame 100 defines a plurality of through holes 110 arranged along an extending direction of the adjustment frame 100 .
[0040] It should be noted that the axes of the through holes 110 provided on the adjustment frame 100 are parallel to each other, and the distance between the through holes 110 and the number of the through holes 110 can be adjusted according to actual conditions, and are not specifically limited here, as long as the above purpose can be achieved.
[0041] The sliding frame 200 is movably mounted on the adjusting frame 100 .
[0042] See also Figure 3 The limiting assembly includes a latch sleeve 410, an outer latch 420, an inner latch 430 and a latch handle 440. The latch sleeve 410 is arranged on one side of the sliding frame 200, and the outer latch 420 and the inner latch 430 are movably arranged inside the latch sleeve 410. The latch handle 440 can drive the outer latch 420 and the inner latch 430 to move along the axial direction of the through hole 110. The outer latch 420 and the inner latch 430 are used to engage with the through hole 110.
[0043] It can be understood that by applying external force to the latch handle 440, the outer latch 420 and the inner latch 430 can be driven to move along the axial direction of the through hole 110. When the relative position of the sliding frame 200 and the adjusting frame 100 needs to be adjusted, the latch handle 440 is pulled to disengage the outer latch 420 and the inner latch 430 from the through hole 110, thereby moving the sliding frame 200 to the target position of the adjusting frame 100, and then the outer latch 420 and the inner latch 430 are re-engaged with the corresponding through hole 110, so that the relative position of the sliding frame 200 and the adjusting frame 100 can be adjusted, and the sliding frame 200 and the adjusting frame 100 after engagement are relatively fixed.
[0044] See also Figure 4 and Figure 5 Specifically, the limiting assembly connected to the sliding frame 200 is provided with an outer pin 420 and an inner pin 430 for engaging with the through hole 110. The pin handle 440 can drive the outer pin 420 and the inner pin 430 to move along the axial direction of the through hole 110. When the outer pin 420 is only hooked on the rounded corner of the through hole 110 on the adjustment frame 100, the inner pin 430 can also realize the engagement of the limiting assembly with the through hole 110, so that when the sliding frame 200 is subjected to external force, the sliding frame 200 will not slide down rapidly relative to the adjustment frame 100, which can avoid the problem that the adjustment mechanism will drop rapidly when the pin positioning is only hooked on the rounded corner.
[0045] It should be noted that in this embodiment, the adjustment mechanism may further include a pulley seat 300, which is connected to the sliding frame 200 and can move together with the sliding frame 200. The pulley seat 300 is equipped with a steel cable 310. The pulley seat 300 and the steel cable 310 are the main components for the user to exercise. Typically, after adjusting the sliding frame 200, the user manually pulls the steel cable 310 of the pulley seat 300 to perform the exercise. The structure of the adjustment mechanism in the embodiment of the present application is not limited to the source of the external force, and can also be used for other equipment such as the installation and placement of a barbell rack.
[0046] Preferably, the outer pin 420 is movably sleeved on the outside of the inner pin 430, and the outer pin 420 and the pin sleeve 410 are respectively provided with a first stopper 421 and a second stopper 411 at the end facing away from the through hole 110, and the inner pin 430 is provided with a protrusion structure 431 at the end close to the adjustment frame 100, and a first elastic member 450 is provided between the protrusion structure 431 and the first stopper 421, and a second elastic member 460 is provided between the first stopper 421 and the second stopper 411, and the first elastic member 450 and the second elastic member 460 are respectively used to drive the inner pin 430 and the outer pin 420 to move close to the through hole 110.
[0047] It can be understood that a second elastic member 460 is provided between the first stop member 421 of the outer pin 420 and the second stop member 411 of the pin sleeve 410, and a first elastic member 450 is provided between the first stop member 421 of the outer pin 420 and the protrusion structure 431 of the inner pin 430. By pulling the inner pin 430, the first elastic member 450 and the second elastic member 460 can be successively compressed. The inner pin 430 and the outer pin 420 are pulled out of the through hole 110 by an external force. After the external force is removed, the inner pin 430 and the outer pin 420 are respectively engaged with the corresponding through hole 110 under the action of the first elastic member 450 and the second elastic member 460 in the compressed state.
[0048] It should be noted that when the protrusion structure 431 compresses the first elastic member 450, its end face close to the through hole 110 should be located outside the end face of the outer pin 420, to ensure that the inner pin 430 pops out faster than the outer pin 420 under the action of the first elastic member 450. In addition, the shape and size of the outer pin 420 and the inner pin 430 can be adjusted according to actual conditions and can be adapted to the through hole 110.
[0049] Preferably, the latch handle 440 is fixedly connected to one end of the inner latch 430 facing away from the adjustment frame 100 , and the latch handle 440 pulls the inner latch 430 to compress the first elastic member 450 and the second elastic member 460 .
[0050] It can be understood that in this embodiment, the latch handle 440 is preferably fixedly connected to the end of the inner pin 430 away from the adjustment frame 100, and the inner pin 430 is pulled by the latch handle 440 to drive the outer pin 420 to move, and the first elastic member 450 and the second elastic member 460 are successively compressed to produce deformation.
[0051] Preferably, the first elastic member 450 and the second elastic member 460 are springs.
[0052] In this embodiment, the first elastic member 450 and the second elastic member 460 are specifically springs. It should be noted that the elastic force of the second elastic member 460 should be greater than that of the first elastic member 450. The elastic force of the first elastic member 450 and the second elastic member 460 can also be adjusted according to actual conditions as long as the above-mentioned purpose can be achieved.
[0053] See also Figure 2 Preferably, the adjustment mechanism further includes a handle member 500, which is connected to the sliding frame 200, and the handle member 500 and the limiting assembly are arranged on the same side.
[0054] It can be understood that the adjustment mechanism of this embodiment also includes a handle member 500, which is connected to one side of the sliding frame 200. When an external force acts on the limit assembly to cause the inner pin 430 and the outer pin 420 to disengage from the through hole 110, the sliding frame 200 is moved up and down by manually gripping the handle member 500. The external force acting on the handle member 500 can prevent the sliding frame 200 from suddenly sliding off when the inner pin 430 and the outer pin 420 are pulled apart. The provision of the handle member 500 facilitates the movement process of the sliding frame 200.
[0055] Preferably, the handle piece 500 is covered with a handle cover 510 , and the outer periphery of the handle cover 510 is provided with a non-slip surface.
[0056] It is understandable that the handle member 500 is covered with a handle cover 510 , and the outer periphery of the handle cover 510 is provided with an anti-slip surface, which can reduce the occurrence of accidents and increase the safety of the entire adjustment mechanism.
[0057] Preferably, the outer plug 420, the inner plug 430 and the plug sleeve 410 are coaxially arranged.
[0058] It should be noted that the coaxial arrangement of the outer pin 420, the inner pin 430 and the pin sleeve 410 facilitates the adjustment process of the entire adjustment mechanism. In addition, the relative positions of the axes of the outer pin 420, the inner pin 430 and the pin sleeve 410 can also be slightly adjusted according to actual conditions to achieve the above-mentioned purpose.
[0059] Preferably, the cross-sections of the outer pin 420 and the inner pin 430 perpendicular to the axial direction are annular and circular, respectively.
[0060] It is understandable that the outer pin 420 and the inner pin 430 need to be adapted to the through hole 110 , the outer pin 420 is sleeved on the outside of the inner pin 430 , and the cross-sections of the outer pin 420 and the inner pin 430 perpendicular to the axial direction are annular and circular respectively.
[0061] Preferably, the cross-sectional diameter of the through hole 110 perpendicular to the axial direction is larger than the cross-sectional diameter of either the outer plug pin 420 or the inner plug pin 430 perpendicular to the axial direction.
[0062] It can be understood that the outer pin 420 and the inner pin 430 need to be inserted into the through hole 110 to achieve a relatively fixed position of the sliding frame 200 and the adjustment frame 100, and the cross-sectional diameter of the through hole 110 perpendicular to the axial direction should be larger than the cross-sectional diameter of the outer pin 420 and the inner pin 430 perpendicular to the axial direction to facilitate the engagement or disengagement of the outer pin 420 and the inner pin 430.
[0063] In summary, the present invention is an adjustment mechanism, including an adjustment frame 100, a sliding frame 200 and a limiting assembly, wherein the adjustment frame 100 is provided with a plurality of through holes 110 arranged along the extension direction of the adjustment frame 100; the sliding frame 200 is movably sleeved on the adjustment frame 100; the limiting assembly includes a latch sleeve 410, an outer latch 420, an inner latch 430 and a latch handle 440, the latch sleeve 410 is provided on one side of the sliding frame 200, the outer latch 420 and the inner latch 430 are movably provided inside the latch sleeve 410, and the latch handle 440 can drive the outer latch 420 and the inner latch 430 to move along the axial direction of the through hole 110, and the outer latch 420 The inner pin 430 is used to engage with the through hole 110; the outer pin 420 is movably sleeved on the outside of the inner pin 430, and the outer pin 420 and the pin sleeve 410 are respectively provided with a first stopper 421 and a second stopper 411 at the end away from the through hole 110. The inner pin 430 is provided with a protrusion structure 431 at the end close to the adjustment frame 100, and a first elastic member 450 is provided between the protrusion structure 431 and the first stopper 421, and a second elastic member 460 is provided between the first stopper 421 and the second stopper 411. The first elastic member 450 and the second elastic member 460 are respectively used to drive the inner pin 430 and the outer pin 420 to move close to the through hole 110.
[0064] Specifically, the limiting assembly connected to the sliding frame 200 is provided with an outer pin 420 and an inner pin 430 for engaging with the through hole 110, a second elastic member 460 is provided between the first stopper 421 of the outer pin 420 and the second stopper 411 of the pin sleeve 410, and a first elastic member 450 is provided between the first stopper 421 of the outer pin 420 and the protrusion structure 431 of the inner pin 430. By pulling the inner pin 430, the first elastic member 450 and the second elastic member 460 can be successively compressed. By pulling the inner pin 430 and the outer pin 420 by external force, After disengaging from the through hole 110 and then removing the external force, the inner pin 430 and the outer pin 420 are respectively engaged with the corresponding through hole 110 under the action of the first elastic member 450 and the second elastic member 460 in a compressed state. When the outer pin 420 is only hooked on the rounded corner of the through hole 110 on the adjustment frame 100, the inner pin 430 can also realize the engagement of the limit assembly with the through hole 110, so that when the sliding frame 200 is subjected to external force, the sliding frame 200 will not slide down rapidly relative to the adjustment frame 100, which can avoid the problem of the adjustment mechanism rapidly falling when the pin positioning is only hooked on the rounded corner.
