[0034] Embodiment:

[0035] The embodiment of the present application discloses a gear shifting operation mechanism suitable for a rope climbing machine, referring to Figure 1 and Figure 2 , the whole rope climbing machine is shown. The mechanism of the present scheme is applied to the rope climbing machine, including a gearbox mechanism 1, an operating lever 2 arranged on the gearbox mechanism 1, and a fulcrum structure 3 arranged on the gearbox mechanism 1 for the operating lever 2 to swing. The operating lever 2 on the gearbox mechanism 1 makes a lever movement on the fulcrum structure 3, so that one action of gear shifting (speed regulation) can be realized.

[0036] In order to solve the protection problem, it is necessary to assemble and design a shell 4, so the present scheme is applied to the improved shell 4.

[0037] The gearbox mechanism 1 and the operating lever 2 are assembled in the shell 4 of the rope climbing machine, and the upper side surface 411 of the shell 4 is provided with a notch 41, and the vertical surface 412 of the notch 41 is provided with a mounting groove 42. Preferably, the notch 41 includes the side surface 411 and the vertical surface 412, so that the shape of the notch 41 is designed as the side surface 411 and the vertical surface 412, so as to facilitate finger operation and installation.

[0038] We can also see in Figure 2 that the limiting cover 5 is fixed on the vertical surface 412, and the fixing points of the limiting cover 5 are distributed upward and downward. In this way, the assembly and fixing mode of the limiting cover 5 is used for the design and installation position selection of such notch 41, so that the component assembly is very easy, and the screwing is easier.

[0039] Then, combined with Figure 2 , Figure 4 and Figure 5 , it is understood that the limiting cover 5, the push block 6 and the special-shaped snap spring 7 are assembled on the mounting groove 42. Figure 2The upper and lower edges of the installation slot 42 are provided with gear arc grooves 421, preferably, two gear arc grooves 421 are respectively arranged on the upper and lower edges of the installation slot 42, and the specific embodiment is two gears, i.e. low gear and high gear. The arch bridge part 71 of the snap spring 7 is respectively arranged on the upper and lower edges. Specifically, the snap spring 7 is a single metal wire structure, has a symmetric structure and a “” shaped opening 72. The unique shape of the snap spring 7 can realize obvious gear feeling, and the arch bridge part 71 can be easily worn out of the through slot 62, which not only limits the snap spring 7 itself, but also enables the snap spring 7 to cooperate with the installation slot 42 to move

[0040] In Figure 5 It can be seen that the back of the dial block 6 is provided with a surrounding edge part 61, the upper and lower edges of the surrounding edge part 61 are provided with through slots 62, the upper and lower edges of the snap spring 7 are provided with arch bridge parts 71, the arch bridge parts 71 pass through the through slots 62 and abut against the upper and lower edges of the installation slot 42. The limiting cover 5 is provided with a movable window 51, the handle part 63 of the dial block 6 passes through the movable window 51, the surrounding edge part 61 is further provided with a clamping groove 64, and the operating rod 2 is clamped in the clamping groove 64. The limiting cover 5 is fixed on the notch 41, and the dial block 6 is cooperated with the limiting cover 5 and the installation slot 42 to slide to dial the operating rod 2.

[0041] In the present scheme, the notch 41 formed on the shell 4 provides an operating space and an installation space. The limiting cover 5 is used to limit the movement of the dial block 6, the dial block 6 can be dialled in the movable window 51, so that the snap spring 7 slides on the upper and lower edges of the installation slot 42 (slides between the two gear arc grooves 421 to switch gears), when the snap spring 7 slides to the position of the gear arc groove 421, the feeling of the finger has a clear paragraph feeling (gear feeling), which can also play a role in assisting the current gear to keep the position and will not easily leave the gear. In terms of assembly, the special shape of the snap spring 7 is deformed and clamped, and the dial block 6 is used to link the operating rod 2, so as to realize the gear shifting of the gearbox mechanism 1 by operating the dial block 6 on the shell 4. Since the whole assembly and installation mode is firm and reliable, the operation is flexible, and the shell 4 is protected, the service life of the gearbox mechanism 1 or the internal structure of the rope climbing machine can be greatly improved.

[0042] In Figure 4In the transmission mechanism 1, a control ring 11 with an open loop structure is included, both ends of an open loop opening 111 of the control ring 11 are provided with threaded holes 112, and adjusting bolts are assembled on the threaded holes 112. The control ring 11 is sleeved on the clutch gear ring 15, is matched on the clutch gear ring 15 and slides left and right along the axis direction of the main shaft 12, and gear shifting is realized. The control ring 11 and the clutch gear ring 15 are rotationally matched in the circumferential direction and exist friction. The adjusting bolts are used to change the spacing of the open loop opening 111. The control ring 11 is made of plastic or nylon material, is convenient to assemble, and the side surface 411 has an oil storage groove to add lubricating oil. Compared with the buckle connection mode of the open loop opening 111, the scheme utilizes the cooperation of the threaded hole 112 and the adjusting bolt to realize the loose opening degree adjustment. The control ring 11 can change the spacing of the open loop opening 111 by using the adjusting bolt, so as to change the looseness degree. After long-term use and wear, the control ring 11 can still be continuously used by tightening the open loop opening 111, the replacement time is prolonged, and the service life is improved.

[0043] Finally, with reference to Figure 4 and Figure 6 , the transmission mechanism 1 further includes a main shaft 12, a first transmission composite gear 13, a linking gear 14, a clutch gear ring 15 and a second transmission composite gear 16. The main shaft 12 is provided with a spline portion 121, the second transmission composite gear 16, the linking gear 14 and the first transmission composite gear 13 are sequentially sleeved on the spline portion 121, the linking gear 14 is clamped with the spline portion 121, the first transmission composite gear 13 and the second transmission composite gear 16 are rotationally matched on the spline portion 121, and the clutch gear ring 15 is sleeved and clamped on the linking gear 14 and slides left and right to link the first transmission composite gear 13 or the second transmission composite gear 16.

[0044] The first transmission composite gear 13 and the second transmission composite gear 16 have different gear ratios (transmission ratios), so that when the main shaft 12 is linked with one of them, different speeds and torques are obtained, and gear shifting is realized.

[0045] The main shaft 12 in the transmission gear box adopts the spline portion 121, so that the processing is facilitated, the linking gear 14 has a spline hole, so that the spline portion 121 and the linking gear 14 can be closely and reliably matched, and the first transmission composite gear 13 and the second transmission composite gear 16 are both light holes. When the first transmission composite gear 13 and the second transmission composite gear 16 are rotationally matched with the spline portion 121, the contact area can be greatly reduced, the friction resistance can be reduced, and the rotation fluency can be improved. Compared with the prior art, the rotationally matched light shaft and light hole have more obvious advantages, and the disadvantages caused by the large contact surface and large resistance in the prior art are overcome.

[0046] Thus, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, and the above description is only for the preferred embodiments of the present application and is not intended to limit the present application; for those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
