The main functions of the rock climbing trainer's hand and foot linkage mechanism of the present invention will be clearly shown in the following embodiments.

Referring to the first to third figures, the present invention provides a rock climbing trainer linkage mechanism comprising: a frame (1), four guide rods (2), two handles (3), and a certain pulley ( 4), two upper sliding groups (5), one upper wire rope (6), two connecting rods (7), two foot pedals (8), two lower sliding groups (9), and a lower wire rope (10) An adjustable pulley block (11), two chains (12), two sprockets (13) and an adjustment bracket (14).

The four guiding rods (2) are arranged in groups of two, and each guiding rod (2) is composed of an upper guiding rod (21) and a lower guiding rod (22), and the upper guiding rod (21) and the lower portion The guide rods (22) are connected by a guide rod fixing seat (23) to reduce the processing difficulty. Dividing the guide rod (2) into upper and lower parts reduces the processing cost, and increasing the support in the middle can reduce the influence of factors such as insufficient steelity caused by the excessive span of the guide rod (2).

The lower part of the four guiding rods (2) is fixed on the frame (1), and the two upper sliding groups (5) are respectively sleeved on the upper part of the four guiding rods (2). The two handles (3) are respectively fixed on the fixing holes (51) of the two upper sliding groups (5), and three sets of handle mounting positions are provided on the upper sliding group (5), and the extreme positions are provided. Convenient gear position replacement method can be used to meet the needs of different body types.

The fixed pulley (4) is rotatably mounted on the top of four guiding rods (2), and the middle portion of the upper wire rope (6) is wound on the fixed pulley (4) and both ends of the upper wire rope (6) They are respectively fixed on the two upper sliding groups (5).

The two lower sliding groups (9) are respectively sleeved in the lower part of the four guiding rods (2), and the two lower sliding groups (9) are respectively slid through the connecting rods (7) and the two upper sliding groups Group (5) cross-connect (as shown in the fourth figure), the left handle (31) and the right foot pedal (82), the right handle (32) and the left foot pedal (81) respectively Two sets of sliding groups are formed by connecting two connecting rods (7), thereby ensuring that the left and right feet, the right hand and the left foot are synchronized during the movement.

The adjusting bracket (14) is composed of an adjusting sleeve (141), an adjusting rod (142) and a latch (143). The lower end of the adjusting rod (142) is fixed on the frame (1), and the adjusting sleeve (141) is sleeved on the adjusting rod (142) and fixed by the bolt (143), the adjustable pulley block ( 11) fixedly mounted on the adjustment sleeve (141).

The two sprockets (13) are respectively rotatably mounted on the frame (1) by a one-way bearing and located at a lower portion of the four guide rods (2), and the middle portions of the two chains (12) are respectively Winding on the two sprockets (13), the inner ends of the two chains (12) are connected by the lower wire rope (10), and the lower wire rope (10) is wound around the adjustable pulley block (11) The outer ends of the two chains (12) are respectively connected to the two lower sliding groups (9) to keep the two lower sliding groups (9) synchronized. This creation uses a one-way bearing to ensure that the foot pedal (8) needs to be forced when going down, and no force is required when going up to meet the force rule of rock climbing.

The upper sliding group (5) of the present creation is connected by a wire rope, and the lower sliding group (9) is connected by a chain (12) through a sprocket (13) (connected to a transmission shaft) and then connected by a wire rope (10), and the adjustable pulley block (11)Adopting the adjustable fixed pulley to achieve the tightness adjustment under the condition that the transmission ratio is constant, and achieve the purpose of linkage between the two sets of sliding groups. Therefore, the creation can not only ensure the coordination of the left and right during the movement, but also guarantee The limbs are linked to maximize the human climbing movement. According to the demand, the handle (3) adopts a self-rotating structure, and the foot pedal (8) can be rotated within a certain angle range, which can give the user a better experience and better ensure the safety of use.

However, the above description is only a preferred embodiment of the present invention. When it is not possible to limit the scope of the creation of the present invention, that is, the simple equal change and modification according to the scope of the patent application and the new description of the creation are all the creation patents.
