[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] The core of the utility model is to provide an auxiliary lifting device, which can reduce the training intensity of the user and break through the use limitations of the rope climbing machine. Another core of the utility model is to provide a rope climbing machine including the auxiliary lifting device.

[0043] Please refer to Figures 1 to 5 The utility model provides an auxiliary lifting device for a rope climbing machine 0, comprising a slide rail 1, a movable assembly and a transmission member. The slide rail 1 is arranged longitudinally and one end of which is arranged at the bottom of the rope climbing machine 0; the movable assembly comprises a counterweight 22, an auxiliary rope 23 and a sliding member, the counterweight 22 is used to be arranged at the top of the sliding member, and the sliding member is slidably arranged on the slide rail 1, the auxiliary rope 23 is connected to the sliding member, and can drive the counterweight 22 to move along the slide rail 1; the transmission member is arranged at the top of the rope climbing machine 0, and the free end of the auxiliary rope 23 bypasses the transmission member and extends to the bottom to connect to both sides of the user.

[0044] Specifically, Figure 2As shown, the slide rail 1 is arranged longitudinally so as to guide the sliding member to slide longitudinally. Optionally, the slide rail 1 is the circumferential surface of a straight rod, and the straight rod passes through the first through hole in the middle of the sliding member to achieve sliding cooperation between the sliding member and the slide rail 1. Alternatively, the slide rail 1 is a groove opened on the side of the straight rod, etc. It should be noted that the number and type of slide rails 1 are not limited as long as the above functions can be achieved.

[0045] A counterweight block 22 is placed on the top of the sliding member, so that the sliding member can drive the counterweight block 22 to move up and down in the longitudinal direction. The counterweight block 22 can be a barbell plate or an iron block with a first through hole in the middle, etc. Preferably, the top of the sliding member has a columnar protrusion, which passes through the first through hole in the middle of each counterweight block 22, so that the counterweight blocks 22 are stacked in sequence on the top surface of the sliding member along the longitudinal direction.

[0046] The bottom of the sliding member is slidably matched with the auxiliary rope 23 wrapped around its own circumference, so that the auxiliary rope 23 can both adaptively move its position and transmit power between the sliding member and the user. The auxiliary rope 23 can be an elastic rope or a nylon rope, etc. It can be realized that the bottom of the sliding member is an arched convex structure, and the middle part of the arched convex structure is provided with a groove along the length direction of its circumference, and the auxiliary rope 23 is embedded in the groove.

[0047] The transmission member is arranged at the top of the rope climbing machine 0, and is used to support the auxiliary rope 23 and slide with the auxiliary rope 23. Optionally, the transmission member is a fixed pulley or the above-mentioned arched protrusion structure, etc., as long as the above-mentioned function can be achieved.

[0048] During installation, if Figure 1 As shown, the auxiliary lifting device is arranged at the bottom of the rope climbing machine 0, wherein both ends of the auxiliary rope 23 extending around the sliding member are used to connect with the user. Specifically, one end of the auxiliary rope 23 is used to connect with one side of the user's waist, and the other end of the auxiliary rope 23 extends from top to bottom through the transmission member at the top of the rope climbing machine 0, and then extends upward again after bypassing the sliding member to bypass another transmission member at the top of the rope climbing machine 0 bracket, and finally extends from top to bottom to be connected with the other side of the user's waist.

[0049] When using, Figures 2 to 5 As shown, a preset number of counterweights 22 are selected and placed on the sliding member. When the user starts to climb, the counterweights 22 on the transmission member fall down, giving the user an upward pulling force. The auxiliary lifting device can help the user overcome part or all of the gravity and effectively control the user's training intensity, so that the rope climbing machine 0 can be suitable for all kinds of people, greatly breaking through its usage limitations.

[0050] In some embodiments, the sliding member includes a sliding seat 24 and a movable pulley 21. The sliding seat 24 is slidably arranged on the slide rail 1, and the movable pulley 21 is rotatably arranged at the bottom of the sliding seat 24. The auxiliary rope 23 is wrapped around the circumference of the movable pulley 21, and the auxiliary rope 23 bypasses the transmission member and is detachably connected to the user.

[0051] like Figures 2 to 5 As shown, the sliding seat 24 is a plate-like structure or a block-like structure, and the sliding seat 24 has a protruding structure or a through hole that is matched with the slide rail 1, and a movable pulley 21 is fixed to the bottom of the sliding seat 24, so that the movable pulley 21 can be raised and lowered with the sliding seat 24, and the movable pulley 21 can rotate on its own. When in use, the auxiliary rope 23 rolls with the movable pulley 21, which is beneficial to prolonging the service life of the auxiliary lifting device.

[0052] In some embodiments, the number of movable pulleys 21 is two, and the line connecting the rotation centers of the two movable pulleys 21 is horizontal.

[0053] like Figures 1 to 5 As shown, when the same width requirement is met, the thickness of two laterally arranged movable pulleys 21 is less than the thickness of one movable pulley 21, and two movable pulleys 21 are arranged to cooperate with the auxiliary rope 23, which helps to reduce the space occupied by the movable pulley 21 and is conducive to the development of the auxiliary lifting device towards miniaturization.

[0054] In some embodiments, the counterweight block 22 is slidably matched with the slide rail 1, and the side of the counterweight block 22 can be contacted with the slide rail located on the side of the counterweight block 22 to achieve a sliding fit. Such a setting is conducive to preventing the counterweight block 22 from falling and guiding the counterweight block 22 to rise and fall smoothly.

[0055] In some embodiments, the slide rail 1 is a straight rod. With this arrangement, the auxiliary lifting device has a simple structure and low cost. In some embodiments, there are two slide rails 1, which are arranged in parallel and penetrate each counterweight 22 to guide the counterweight 22 to move along the slide rail 1. Figures 2 to 5 As shown, the two slide rails 1 are two straight rod structures, and a counterweight block 22 is arranged between the two slide rails 1. Preferably, the counterweight block 22 has two longitudinal through holes for cooperating with the two slide rails 1. Such an arrangement further ensures the stable operation of the auxiliary lifting device.

[0056] In some embodiments, a guide sleeve 25 is provided at the bottom of the sliding seat 24, and the guide sleeve 25 is slidably sleeved on the outer periphery of the slide rail 1. The guide sleeve 25 provided at the bottom of the sliding member is conducive to the auxiliary counterweight block 22 sliding along the slide rail 1, effectively ensuring the smooth operation of the auxiliary lifting device.

[0057] In some embodiments, a fixing component 3 is also included, and the fixing component 3 includes a mounting component 31 and a connecting component 32; the mounting component 31 is arranged at the top of the slide rail 1, and the connecting component 32 is arranged at the bottom of the mounting component 31; the counterweight block 22 can be optionally detachably connected to the connecting component 32.

[0058] like Figures 2 to 5 As shown, the fixing component 3 is located at the top, and the connecting component 32 is arranged on the slide rail 1 through the mounting member 31, and is used to lift part or all of the counterweight block 22. It can be realized that the connecting component 32 is a hook or a clamping part, etc., and hooks or clamping parts are arranged on both sides of the long strip mounting member 31, and ears or clamping parts matching therewith are arranged on the side of the counterweight block 22, so as to realize a detachable fixed connection of the top counterweight block 22, and the above-mentioned implementation method can also be adopted between adjacent counterweight blocks 22.

[0059] When in use, a preset number of counterweights 22 are fixedly connected to the connecting assembly 32, so that spare or temporarily unused counterweights 22 are hung on the mounting member 31 through the connecting assembly 32, which facilitates the use of the auxiliary lifting device.

[0060] In some embodiments, the connecting assembly 32 includes a plug-in rod 321 and a selection rod 322 parallel to the slide rail 1; the connecting end of the selection rod 322 is located at the bottom of the mounting member 31, and the selection rod 322 has a plurality of transverse first plug-in holes 3221 along its length; the counterweight block 22 has a longitudinal connecting hole 221 through which the selection rod 322 can pass, and the counterweight block 22 also has a second plug-in hole 222 corresponding to the first plug-in hole 3221, and the plug-in rod 321 can be optionally inserted into the second plug-in hole 222 and the corresponding first plug-in hole 3221.

[0061] like Figure 2 As shown, the lower end of the selection rod 322 in the connecting assembly 32, i.e., the connecting end, is located below the mounting member 31, so that the counterweight block 22 can contact and cooperate with the connecting end of the selection rod 322; the selection rod 322 is parallel to the slide rail 1, and the connecting holes 221 of each counterweight block 22 are all colinear with the selection rod 322, so that the selection rod 322 can be inserted into the connecting holes 221 of each counterweight block 22 sliding along the slide rail 1, and the connecting hole 221 can be a first through hole or a through hole parallel to the first through hole.

[0062] The first plug-in holes 3221 arranged along the length direction of the selection rod 322 can correspond to the second plug-in holes 222 of the counterweight blocks 22 in sequence. The length direction of each first plug-in hole 3221 and the length direction of each second plug-in hole 222 are parallel. It is worth noting that the length direction of the first plug-in hole 3221 and the length direction of the second plug-in hole 222 are both at a non-zero angle with the length direction of the selection rod 322, such as 30° or 90°.

[0063] Furthermore, the peripheral surface of the plug-in rod 321 has a magnetic layer, and the counterweight block 22 can be adsorbed by the magnetic layer. When in use, after the plug-in rod 321 is inserted into the first plug-in hole 3221, there is suction between the magnetic layer and the connected counterweight block 22. Such a setting is conducive to preventing the plug-in rod 321 from falling off from the first plug-in hole 3221 and the second plug-in hole 222, thereby greatly improving safety.

[0064] The plug rod 321 can be inserted into the first plug hole 3221 and the second plug hole 222 at the same time. Figure 3 In the state shown, the two ends of the auxiliary rope 23 are fixed to the user's waist, and the user squats slightly to lift all the selected irons until Figure 1 The state shown in the figure is shown, and then the second insertion hole 222 of the appropriate counterweight block 22 is selected to be inserted into the insertion rod 321, so that a preset number of counterweight blocks 22 can be hung on the selection rod 322, and the remaining counterweight blocks 22 are stacked above the movable assembly and moved accordingly, as shown in the figure. Figure 4 As shown; after the training is over, the user squats slightly after landing to lift all the selected irons until Figure 1 The state shown in FIG. 1 is shown in FIG. 1 , and the plug rod 321 is inserted into the second plug hole 222 of the bottom counterweight block 22, as shown in FIG. Figure 5 As shown, it is ensured that the user can safely and easily release the end of the auxiliary rope 23. With such arrangement, the auxiliary lifting device has a relatively simple structure, is easy to operate, has a low cost, and is easy to use.

[0065] In some embodiments, a second plug hole 222 is provided on the side of the mounting member 31. Figure 3 As shown, a second plug hole 222 is provided on the side of the mounting member 31 for placing the plug rod 321, which effectively avoids the possibility of the plug rod 321 being lost when it is not inserted into the first plug hole 3221 and the second plug hole 222, and is convenient for taking it for use before training begins.

[0066] It is worth noting that the second plug-in hole 222 of the mounting member 31 and the second plug-in hole 222 of the counterweight block 22 may be the same or different, as long as the above-mentioned functions can be achieved.

[0067] In some embodiments, a frame member 4 is also included, and the two ends of the slide rail 1 are arranged on the top and bottom edges of the frame member 4; the top edge of the frame member 4 has two second through holes 41 for the auxiliary rope 23 to pass longitudinally, one of the second through holes 41 is located on the front side of the counterweight block 22, and the other second through hole 41 is located on the back side of the counterweight block 22.

[0069] Two second through holes 41 are set on the top edge of the frame member 4 to limit the position of the auxiliary rope 23. The auxiliary rope 23 passing through the second through holes 41 and connected to the movable pulley 21 is located on both sides of the counterweight block 22, avoiding interference between the auxiliary rope 23 and the movable counterweight block 22, which is beneficial to ensure the smooth operation of the auxiliary lifting device and effectively reduce the wear of the auxiliary rope 23.

[0070] Optionally, when two movable pulleys 21 are used, the tangent direction of the bottom of the two movable pulleys 21 is parallel to the connecting direction of the two second through holes 41 .
