As shown in fig. 1-9, the climbing machine generally comprises a frame 100, two exercise modules 200 and a synchronizing assembly 300, wherein the exercise modules 200 are respectively arranged on two sides of the frame 100, the exercise modules 200 comprise a climbing mechanism 2 and a sliding guide mechanism 1 for guiding the climbing mechanism 2 to reciprocate up and down, the climbing mechanism 2 comprises a handle 21, a pedal 22 and a connecting frame 23, the handle 21 and the pedal 22 are respectively arranged on the connecting frame 23, and the connecting frame 23 can reciprocate up and down relative to the frame 100; wherein the exercise modules 200 on both sides of the frame 100 are connected together by the synchronization assembly 300 to achieve synchronous and reverse sliding.

The improvement points of the climbing machine are explained at least from the following two aspects. In the first improvement point, a newly designed sliding guide mechanism 1 is adopted to ensure that a climbing mechanism 2 can smoothly slide back and forth; in an improvement point two, a new synchronizing assembly 300 is used to reduce noise during movement. And the two improvement points can be independently applied to the climbing machine for use, and the specific description is as follows.

Firstly, the improvement aiming at the sliding guide mechanism 1. The slide guide mechanism 1 includes a guide bar 11 and a guide bush assembly 12, and the guide bush assembly 12 includes: an outer sleeve 121, an inner sleeve 122, an oil storage member 123, and two installation stoppers 124; wherein, the inner sleeve 122 is positioned in the outer sleeve 121 and can slide relative to the outer sleeve 121, the oil storage part 123 absorbs lubricating oil, and the oil storage part 123 is arranged in the outer sleeve 121 and positioned at the end position of the inner sleeve 122; the installation stoppers 124 are provided at the corresponding ends of the outer sleeve 121, and the inner sleeve 122 and the oil storage member 123 are located between the two installation stoppers 124; wherein, the inner sleeve 122 is used for sliding in the outer sleeve 121 to press the oil storage part 123 to release the lubricating oil; in addition, the inner sleeve 122 of the guide sleeve assembly 12 is sleeved on the guide rod 11. Specifically, the inner sleeve 122 is typically made of a wear-resistant material (e.g., nylon, without limitation) that is capable of reciprocating relative to the guide bar 11. During the reciprocating sliding of the inner sleeve 122 along the guide rod 11, the inner sleeve 122 can move relative to the outer sleeve 121, and particularly, when the guide sleeve assembly 12 slides along the guide rod 11 and performs the reverse movement, the inner sleeve 122 will move relative to the outer sleeve. Thus, during the reciprocal sliding of the guide sleeve assembly 12 on the guide rod 11, the inner sleeve 122 will also perform a certain amount of reciprocal movement within the outer sleeve 121. The inner sleeve 122 moving back and forth presses the oil reservoir 123 at the end position thereof, and the lubricant oil in the oil reservoir 123 is squeezed out after the oil reservoir 123 is pressed. The extruded lubricant lubricates the inner wall of the inner sleeve 122 to ensure smooth reciprocating movement of the inner sleeve 122 on the guide rod 11. Preferably, oil storage parts 123 may be respectively provided at both ends of the outer sleeve 121, and the inner sleeve 122 is positioned between the two oil storage parts 123, and the inner sleeve 122 will alternately press the oil storage parts 123 at the corresponding ends during the reciprocating sliding. In the process that the sliding direction of the inner sleeve 122 is reversed and the inner sleeve continues to slide, the oil storage part 123 at the front end position in the moving direction is extruded and releases lubricating oil, and the released lubricating oil enters a gap between the guide rod 11 and the inner sleeve 122 to play a role in good lubrication; meanwhile, the oil storage part 123 at the rear end position in the moving direction is in a loose state, and the oil storage part 123 at the rear end position can recollect the lubricating oil adhered on the absorption guide rod 11. In the reciprocating process, on one hand, enough lubricating oil can be obtained for lubrication protection when the inner sleeve 122 slides forwards and backwards, and on the other hand, the lubricating oil released by the squeezed oil storage part 123 is re-absorbed by the oil storage part 123 with the other end in a loose state, so that the lubricating oil can be recycled for a long time, and the purposes of adding the lubricating oil for maintenance at longer time intervals or adding the lubricating oil without maintenance can be achieved. Wherein, outer sleeve 121 and inner sleeve 122 are clearance fit to satisfy inner sleeve 122 can reduce the range that inner sleeve 122 rocked for outer sleeve 121 when sliding in outer sleeve 121. Due to the clearance fit, the inner sleeve 122 can slide smoothly in the outer sleeve 121, so that the generation of noise caused by resonance due to unsmooth sliding can be effectively avoided, and the noise generated in the use process can be reduced.

Further, the concrete representation entity for the oil storage part 123 may take various forms so as to be capable of adsorbing the lubricating oil and releasing the lubricating oil when being squeezed, for example: the oil storage part 123 includes: the oil absorption pad 1231 absorbs the lubricant, and the retainer ring 1232 is located outside the oil absorption pad 1231 and covers the oil absorption pad 1231. Specifically, the oil absorption pad 1231 can be made of felt or sponge pad and other materials, so that the oil absorption pad has the function of absorbing lubricating oil; the retainer ring 1232 can protect the oil absorption pad 1231 at the outer side thereof to meet the requirement of reliable installation, and meanwhile, the occurrence of the situation that the lubricating oil leaks to the outside can be reduced by shielding the oil absorption pad 1231 at the outer side thereof through the retainer ring 1232.

In order to facilitate assembly of the oil storage member 123, a step surface 1211 for positioning the oil storage member 123 is provided in the outer sleeve 121, and the oil suction pad 1231 abuts against the step surface 1211. Specifically, the oil suction pad 1231 and the retainer ring 1232 are sandwiched between the stepped surface 1211 and the corresponding installation limiting member 124, and the stepped surface 1211 can support and position the oil suction pad 1231. In assembly, after the inner sleeve 122 is inserted into the outer sleeve 121, the oil absorption pad 1231 and the retaining ring 1232 are sequentially inserted into the outer sleeve 121, the oil absorption pad 1231 is positioned by the step surface 1211, and then the installation limiting member 124 is installed at the port position of the outer sleeve 121 to complete installation.

Specifically, during the movement of the inner sleeve 122, the oil absorption pad 1231 on the corresponding side is pressed by the flanging structure 1221, so as to effectively squeeze out the lubricating oil in the oil absorption pad 1231. In the case where the oil storage members 123 are disposed at both ends of the outer sleeve 121, two inner sleeves 122 may be disposed in the outer sleeve 121, the inner sleeves 122 are inserted into the outer sleeve 121 from the corresponding ports of the outer sleeve 121, respectively, and the flange 1221 of the inner sleeve 122 is located outside the step 1211.
