[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-6 The utility model provides a technical solution: an upper limb trainer with a telescopic structure, comprising a protective cover 1, a connecting bolt 2 connected to the inner side of the protective cover 1, a partition 3 provided inside the protective cover 1, a motor 4 installed inside the partition 3, a telescopic assembly 5 provided below the motor 4, the telescopic assembly 5 comprising a driving rod 501 provided below the motor 4, a driving block 502 installed outside the driving rod 501, and a connecting plate 503 provided below the driving block 502;

[0030] A movable telescopic rod 6 is provided at the lower end of the driving block 502, and a spring body 7 is provided on the outer side of the movable telescopic rod 6, a first force-bearing plate 8 is provided on the lower side of the movable telescopic rod 6, and a second force-bearing plate 9 is provided on the front side of the first force-bearing plate 8, a limit block 10 is installed on the outer end of the first force-bearing plate 8, and a positioning block 11 is provided inside the first force-bearing plate 8, a positioning rod 12 is provided on the outer side of the positioning block 11, and a pull rod 13 is connected to the lower side of the positioning block 11;

[0031] The connecting assembly 14 is arranged on the outside of the first force-bearing plate 8, and the connecting assembly 14 includes a fixing block 1401 arranged on the outside of the first force-bearing plate 8, the inside of the fixing block 1401 is connected to the fixing rod 1402, and the outside of the fixing rod 1402 is provided with a fixing ring 1403, which together constitute an upper limb trainer with a telescopic structure.

[0032] like Figure 1 As shown, the protective cover 1 and the connecting bolt 2 are threadedly connected to each other, and the connecting bolt 2 is symmetrically arranged about the center of the protective cover 1. The protective cover 1 is placed on the horizontal frame, and the connecting bolt 2 is screwed on at the contact point between the protective cover 1 and the horizontal frame cross bar, so that the protective cover 1 and the horizontal frame cross bar are connected and reinforced through the connecting bolt 2, which facilitates the rapid assembly of the upper limb trainer.

[0033] like Figure 1 As shown, the driving rod 501 passes through the interior of the driving block 502, and the driving rod 501 and the driving block 502 are connected with each other by relative threads. When the motor 4 is turned on, the motor 4 drives the driving rod 501 to rotate, and the threads on the outside of the driving rod 501 drive the driving block 502 to move. The outer side of the driving block 502 is slidably connected to the inner side of the protective cover 1. At the same time, the vertical spacing between the driving block 502 and the partition 3 changes. When the upper limb trainer needs to be used, the motor 4 can be turned on to drive the driving rod 501 to increase the vertical spacing between the driving block 502 and the partition 3. Conversely, when the upper limb trainer is retracted, the motor 4 is driven in the reverse direction to make the driving block 502 close to the partition 3. By adding a telescopic structure to the upper limb trainer, the space occupation of the upper limb trainer when not in use for a long time can be effectively avoided.

[0034] like Figure 1 and Figure 5As shown, the connecting plate 503 is symmetrically arranged about the center line of the driving block 502, and the limit block 10 is relatively slidably connected to the connecting plate 503, and the movable telescopic rod 6 is symmetrically arranged about the center line of the first force plate 8, and the movable telescopic rod 6 runs through the interior of the spring body 7. When the driving block 502 is adjusted to the corresponding position, the user pulls the pull rod 13 with both hands, and the pull rod 13 passes through the positioning block 11, so that the first force plate 8 and the second force plate 9 move as a whole. The spring body 7 installed on the upper side of the first force plate 8 and the second force plate 9 undergoes elastic deformation at this time. At the same time, the movable telescopic rod 6 moves, and the limit blocks 10 on the outside of the first force plate 8 and the second force plate 9 are slidably connected to the connecting plate 503. The function of the movable telescopic rod 6 is to prevent the spring body 7 from causing the first force plate 8 and the second force plate 9 to deviate in azimuth angle when being pulled, so as to improve the stability of the upper limb trainer when in use.

[0035] like Figure 1 and Figure 4 As shown, the positioning block 11 is relatively engaged with the first force plate 8 and the second force plate 9, and the positioning rod 12 is symmetrically arranged about the center line of the positioning block 11. The positioning block 11 is engaged with the inside of the first force plate 8 and the second force plate 9, and the positioning rod 12 on the outside of the positioning block 11 is a rectangular structure. After being engaged in the grooves corresponding to the first force plate 8 and the second force plate 9, when the user subsequently pulls the pull rod 13, it avoids the situation where the user applies improper force and causes displacement between the first force plate 8 and the positioning block 11, thereby improving the safety of the upper limb trainer when in use.

[0036] like Figure 1 、 Figure 3 and Figure 6 As shown, the fixing block 1401 is relatively engaged with the first force plate 8 and the second force plate 9, and the fixing rod 1402 runs through the interior of the fixing block 1401, and the fixing ring 1403 is symmetrically arranged with respect to the center line of the fixing rod 1402. When the positioning block 11 and the positioning rod 12 are engaged with the groove between the first force plate 8 and the second force plate 9, the first force plate 8 is in contact with the inner side of the second force plate 9, so that the first force plate 8 and the second force plate 9 are in contact with each other. Engage with the fixing block 1401. At this time, the outer sides of the first force plate 8 and the second force plate 9 are in contact with the inner side of the fixing block 1401. After the fixing rod 1402 is passed through the interior of the fixing block 1401, tighten the fixing ring 1403 to strengthen the connection between the fixing block 1401 and the first force plate 8, and the fixing block 1401 and the second force plate 9, so as to facilitate the reinforcement of the installation of the upper limb trainer. This is the method of using the upper limb trainer with a telescopic structure.
