DETAILED DESCRIPTION

[0029] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, and those skilled in the art will appreciate that these descriptions are only descriptive, exemplary, and should not be interpreted as limiting the scope of protection of the utility model.

[0030] It should be noted that: similar signs represent similar items in the following drawings, so once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0031] This embodiment mainly describes a handrail-adjustable ladder fitness equipment, which is specifically as follows:

[0032] As shown in Figures 1 to 10 A handrail-adjustable ladder fitness equipment includes a support frame 2 and a handrail frame 3, the support frame 2 is connected with the ladder machine body 1, the support frame 2 mainly plays a supporting role, the handrail frame 3 is mainly used to provide support force for the hands of a trainer, to ensure that the body of the trainer is in a balanced state during the training process, to avoid falling or injury, the handrail frame 3 has a handrail vertical rod 31, the handrail vertical rod 31 is provided with a plurality of connecting holes 32 in the vertical direction, the support frame 2 has a support vertical pipe 21 for inserting the handrail vertical rod 31, the support vertical pipe 21 is provided with a fixed hole 22 penetrating through the support vertical pipe 21, the fixed hole 22 is provided with a fastener 4, the fastener 4 mainly plays a fixing and limiting role, the handrail vertical rod 31 is inserted into the support vertical pipe 21, and any one connecting hole 32 is aligned with the fixed hole 22 by adjusting the handrail vertical rod 31, one end of the fastener 4 extends into the fixed hole 22 and successively penetrates out of the connecting hole 32 and the fixed hole 22 to fix the handrail vertical rod 31 on the support vertical pipe 21, when the handrail support needs to be adjusted, the fastener 4 is disassembled, the handrail support is adjusted to a suitable height and the connecting hole 32 is aligned with the fixed hole 22, and then the fastener 4 is used to fix the handrail frame on the support vertical pipe 21, in the scheme, the height of the handrail frame 2 is adjustable, the height of the handrail frame 2 can be adjusted according to the height and preference of the trainer, and the adjustment mode is simple and fast, which improves the user experience and reduces the safety risk.

[0033] As shown in Figure 3 , Figure 4 and Figure 10 , the elastic sleeve 5 is arranged between the handrail upright 31 and the support vertical pipe 21, which fills the gap between the handrail upright 31 and the support vertical pipe 21 to enhance the stability of the handrail upright 31. In order to avoid interference of the elastic sleeve 5 during installation and adjustment of the handrail upright 31, an avoiding hole 51 is arranged on the side wall of the elastic sleeve 5, which penetrates the elastic sleeve 5 and corresponds to the connecting hole 32, and the diameter of the avoiding hole 51 is greater than or equal to the diameter of the connecting hole 32. The avoiding hole 51 is a strip-shaped avoiding hole 51, and the lower end of the strip-shaped avoiding hole 51 penetrates the lower end of the elastic sleeve 5. The connecting hole 32 is located in the strip-shaped hole. When adjusting the handrail support, the elastic sleeve 5 is located in the support vertical pipe 21 and is stationary relative to the support vertical pipe 21, and the handrail upright can be slid upward or downward.

[0034] Specifically, in order to avoid the handrail upright 31 from sliding downward and driving the elastic sleeve 5 to slide downward and completely enter the inside of the support vertical pipe 21, causing the handrail upright 31 to be stuck and difficult to adjust, the upper end of the elastic sleeve 5 has a ring-shaped boss 52, and the diameter of the ring-shaped boss 52 is greater than the diameter of the support vertical pipe 21. When the handrail upright 31 slides downward, the ring-shaped boss 52 abuts against the upper end edge of the support vertical pipe 21, and the support vertical pipe 21 has a blocking effect on the elastic sleeve 5.

[0035] As shown in Figure 1 and Figure 2 , in order to improve the stability of the support frame 2 and the handrail frame 3, the support vertical pipe 21 has two, the handrail upright 31 has two and matches with the two support vertical pipes 21 one by one, the body 1 of the ladder machine has two connecting columns 11 which are respectively inserted into the two support vertical pipes 21 and fixed with the support vertical pipes 21. The lower end of each of the two handrail uprights 31 is provided with a notch 33, and the two notches 33 are respectively arranged on the outer side of the connecting column 11 and the two inner side walls of the two notches 33 abut against the connecting column 11. When adjusting the handrail frame 3, the two notches 33 cooperate with the connecting column 11 to limit the handrail upright 31, which can prevent the handrail upright 31 from rotating and shaking.

[0036] As shown in Figure 4 and Figure 9 , the notch 33 is a U-shaped notch 33 with a circular-arc-shaped bottom wall, the groove width of the U-shaped notch 33 is equal to the diameter of the connecting column 11, and the bottom wall of the U-shaped notch 33 matches with the connecting column 11. During the sliding process of the handrail upright 31, the two groove walls of the U-shaped notch 33 are always clamped on the connecting column 11. When the height of the handrail support is adjusted to the lowest, the circular-arc-shaped groove bottom of the U-shaped notch abuts against the connecting column 11, which can provide support for the handrail upright 31 and avoid rotation of the handrail upright 31.

[0037] As shown in Figure 6 , Figure 7 andFigure 10 As shown, the two support risers 21 are each provided with a mounting hole 23 penetrating the support riser 21, and the two connecting columns 11 extend into the support riser 21 through the two mounting holes 23, and the two connecting columns 11 are provided with threaded holes 12 arranged along the length direction of the columns, and the threaded holes 12 are provided with fixing bolts 13 extending into the threaded holes 12 from the mounting holes 23 away from the ladder body 1 and threadedly connected with the threaded holes 12 to fix the ladder body 1 on the two support risers, and the fixing bolts 13 are provided with nuts with a diameter larger than the mounting holes 23, and the nuts can press the outer wall of the support riser 21 to fix the ladder body 1. The two connecting columns 11 are welded with fixing plates 14 close to the ladder body 1, and the fixing plates 14 are fixed on the two support risers 21 by screws, further improving the stability of the ladder body 1.

[0038] Specifically, the fastener 4 includes a fastening bolt and a nut matched with the fastening bolt, when fixing the handrail upright 31 on the support riser 21, the connecting hole 32 is adjusted to be aligned with the fixing hole 22, one end of the fastening bolt extends into the fixing hole 22 and successively penetrates out of the connecting hole 32 and the fixing hole 22, and the nut is sleeved on the fastening bolt to fix the handrail upright 31 and the support riser 21, when it is needed to adjust the handrail upright 31, the nut is removed, and the fastening is disassembled to adjust, the adjustment mode is simple, and in order to facilitate the adjustment, the bolt head of the fastening bolt is designed as an adjustment handle, and the adjustment is relatively labor-saving.

[0039] As shown in the drawings, Figure 1 As shown, the handrail frame 3 includes a U-shaped handrail handle 34 and two handrail uprights 31, and the two handrail uprights 31 are fixedly connected with two free ends of the U-shaped handrail handle 34 away from the support riser 21, and the U-shaped handrail handle 34 is arranged obliquely relative to the two handrail uprights 31, and the U-shaped handrail handle 34 is inclined upward and the opening of the U-shaped handrail handle 34 faces the training.
