[0047] The technical solution of the present utility model will be described clearly and completely below with reference to the accompanying drawings.

[0048] See Figures 1 to 10 A specific embodiment of a slow-down soft ladder is shown. The slow-down soft ladder has high exercise intensity. When in use, all four limbs are located on the ladder, and the hands and feet can be used together to reduce the burden on the knees. It has a simple structure, low production cost, and wide applicability. It can be widely used in gyms and home fitness environments for continuous aerobic exercise and whole-body muscle strengthening training.

[0049] Example 1:

[0050] like Figures 1 to 7When the sprocket 4 is in the upright position, the chain 5 is moved along the ladder 1 so that the user can climb up the ladder and climb on the ladder.

[0051] Further, if Figure 2 As shown, the slow-descent mechanism 2 includes a base 21, a plurality of vertical plates 22 installed on the base 21, and a plurality of damping discs 23 fixedly connected to the vertical plates 22. One side of the damping disc 23 is set as a friction plane 231. The friction plane 231 abuts and rubs against the sprocket 4 to apply resistance to the sprocket 4 to adjust the rotation speed. By setting the friction plane 231 on the side of the damping disc 23 close to the sprocket 4, the friction plane 231 rubs against the sprocket 4 to increase the resistance of the sprocket 4 when it rotates, thereby slowing down the rotation speed of the sprocket 4 and slowing down the movement speed of the chain rope 5.

[0052] Further, if Figure 2 、 Figure 4 and Figure 6 As shown, the sprocket 4 is located between two adjacent vertical plates 22, and the two end faces of the sprocket 4 are respectively in contact with the damping disk 23. The side where the friction plane 231 is in contact with the sprocket 4 is provided with an annular groove 232 for storing the overflowed damping grease. There are two sprockets 4 and two chain ropes 5, which are respectively located on both sides of the base 21. A plurality of cross bars 51 are provided between the two chain ropes 5, and the two chain ropes 5 are moved synchronously along the sprocket 4 through the cross bars 51.

[0053] It can be understood that the chain rope 5 of the slow-descent ladder can be a ring-shaped chain structure or rope, and a plurality of cross bars 51 are provided between the two chain ropes 5. The plurality of cross bars 51 are distributed according to pitches. The material of the cross bars 51 can be selected as wooden poles or metal pipes. The length range of the cross bars 51 is 300 to 1000 mm, and the spacing range between two adjacent cross bars 51 is 200 to 400 mm.

[0054] Further, if Figure 4 and Figure 5As shown, the sprocket 4 includes a plywood circular wheel 41 and a stretching plate 42 arranged on both sides of the plywood circular wheel 41. The outer edge of the stretching plate 42 is bent outward to form an outer edge surface 421, and the circumferential outer wall of the outer edge surface 421 is recessed inward to form a notch 422. The cross bar 51 is engaged with the notch 422 to drive the sprocket 4 to rotate. The bending angle of the outer edge surface 421 is 90°, and the notches 422 are set to be evenly distributed circumferentially along the circumferential outer wall of the outer edge surface 421. The circumference of the dividing circle of the sprocket 4 is four times the pitch of the chain rope 5. The diameter of the four notches 422 is connected to the cross bar 51 in a loose gap fit manner. By setting the outer edge surface 421 on the circumferential outer wall of the stretching plate 42, the force-bearing area is increased and the service life of the stretching plate 42 is extended.

[0055] Further, if Figure 3 As shown, a square shaft 31 is provided at the connection between the main shaft 3 and the sprocket 4, and a square hole sleeve 411 is provided at the center of the plywood round wheel 41 to pass through the stretching plate 42. The square hole sleeve 411 is connected to the square shaft 31 to transmit the torque of the plywood round wheel 41 to the main shaft 3. A square shaft 31 is provided in the middle section of the main shaft 3, and a support cylinder 7 is provided on the square shaft 31 to support the slow-down mechanism 2. A threaded section 35, an elastic sleeve 34 and a pressure bearing 33 are provided at both ends of the main shaft 3 from the outside to the inside; the threaded section 35 is connected to a handwheel nut 8, and the handwheel nut 8 is rotated to adjust the damping The fitting pressure of the disc 23 and the sprocket 4, the elastic sleeve 34 and the pressure bearing 33 are against each other, and the pressure bearing 33 is used as a sliding interface for relative running-in between the vertical plate 22 and the main shaft 3. The square hole sleeve 411 at the center of the plywood round wheel 41 in the sprocket 4 is engaged with the square shaft 31 of the main shaft 3 to transmit torque to drive the main shaft 3 to rotate, the support tube 7 and the slow-down mechanism 2 are against each other, and the two end faces of the support tube 7 are respectively against the vertical plate 22 to ensure that the vertical plate 22 will not be deformed, so that the damping disc 23 on the vertical plate 22 always maintains a state of decryption and fitting with the sprocket 4.

[0056] Further, if Figure 1 As shown, the ladder frame 1 includes a first supporting leg 11, a second supporting leg 12 and a guide groove step 13. The number of the first supporting leg 11 and the second supporting leg 12 are respectively two, which are arranged to be tilted front and back to form a triangular stable support structure for supporting the stability of the ladder frame 1. The guide groove step 13 is stepped and is used as a fixed support structure at the bottom of the ladder frame 1. The first supporting leg 11 and the second supporting leg 12 are combined into a triangular structure to ensure the structural strength of the slow-descent soft ladder during use, and the guide groove step 13 is convenient to use, and maintains overall stability in contact with the ground.

[0057] Example 2

[0058] Based on the first embodiment, this embodiment further improves the structure.

[0059] Further, if Figures 1 to 10As shown, a number of drive disks 6 are sleeved along the middle part of the main shaft 3. The main shaft 3 rotates based on the rotation of the sprocket 4. The drive disk 6 rotates based on the main shaft 3, and the drive disk 6 is offset against the damping disk 23 to adjust the resistance of the main shaft 3. When the resistance is insufficient, the support tube 7 can be shortened or removed to add multiple groups of drive disks 6 to the main shaft 3 to combine with multiple groups of vertical plates 22 and damping disks 23. The damping disk 23 is set on the vertical plate 22. The rotation of the drive disk 6 and the relative rotation friction with the damping disk 23 on the vertical plate 22 generate resistance to slow down the rotation speed. The resistance is adjusted by adding or reducing the number of drive disks 6 and damping disks 23 to change the climbing speed of people on the soft ladder.

[0060] like Figure 10 As shown, this embodiment also provides other installation methods for the slow-descent soft ladder. The soft ladder can be mounted on a wall. Two vertical triangular iron connectors 14 are installed on the side of the base 21 that is close to the wall. The two triangular iron connectors 14 are fixed at a high place on the wall. Two long rods are connected to the lower end of the base 21 to support the structural frame. The bottom is supported by the guide groove step 13 so that the entire soft ladder is leaning against the wall, which can save the first support leg 11 and the second support leg 12 and reduce the used space.

[0061] For example, the above-mentioned soft ladder provides a method of use. In the lower space left by the base 21, a 6-section high shoe cabinet can be made. Because the front is a soft ladder door, the cabinet door of each section should be made into a sliding curtain door that can be pushed up and down. When opened, the cabinet door is hidden at the top of the cabinet body of this section.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art can make some simple modifications, equivalent changes or modifications based on the technical content disclosed above, which fall within the scope of protection of the present invention.
