Specific embodiments

[0022] Please refer to Figures 1-5 The utility model provides a technical scheme: a T type dumbbell for finger wrist rehabilitation, including connecting column 1, counterweight 2, pull handle 3 and connecting head 4, counterweight 2 is arranged with the surface of connecting column 1, and connecting head 4 is arranged with the upper end of connecting column 1, and pull handle 3 is fixedly connected with the upper surface of connecting head 4.

[0023] The specific setting and function of the mounting device 5 and the auxiliary assembly 6 will be described below.

[0024] In this embodiment: the side surface of connecting head 4 is provided with mounting device 5, and the mounting device 5 includes connecting groove 51 and mounting plate 52; the connecting groove 51 is opened in the side surface of connecting column 1; the mounting plate 52 is fixedly connected with the side surface of connecting head 4; the recess 54 is opened in the inside of mounting plate 52; the ball 53 is slidably connected in the inside of recess 54; one end of ball 53 is clamped in the inside of connecting groove 51; the stop block 56 is fixedly connected with the end of ball 53 away from connecting groove 51; the stop block 56 is slidably connected with the inside of recess 54; the first spring 55 is fixedly connected with the surface of ball 53; the end of first spring 55 away from ball 53 is fixedly connected with the inside of recess 54; the sliding rod 58 is slidably connected in the inside of mounting plate 52; and the pressing plate 511 is fixedly connected with the upper end of sliding rod 58.

[0025] Specifically, the lower end of sliding rod 58 is fixedly connected with connecting plate 510, and the upper end of connecting plate 510 is fixedly connected with stop rod 57.

[0026] In this embodiment: by setting stop rod 57, the stop block 56 can be limited, which reduces the situation that the stop block 56 is easily moved randomly in the recess 54, causing the equipment to be difficult to be stably limited when using.

[0027] Specifically, one end of the abutting rod 57 away from the connecting plate 510 is in abutment with the surface of the abutting block 56, and the surface of the sliding rod 58 is sleeved with the second spring 59. The sliding rod 58 is arranged to facilitate the guided movement of the second spring 59.

[0028] Specifically, one end of the second spring 59 is fixedly connected with the surface of the connecting plate 510, and the other end of the second spring 59 away from the connecting plate 510 is fixedly connected with the lower surface of the mounting plate 52. The second spring 59 is arranged to facilitate the application of a reset elastic force to the connecting plate 510.

[0029] In the embodiment, the lower end of the connecting column 1 is provided with an auxiliary assembly 6, the auxiliary assembly 6 includes a limiting plate 61 and a positioning hole 62, the positioning hole 62 is opened in the side surface of the connecting column 1, the limiting plate 61 is arranged on the side surface of the lower end of the connecting column 1, the inside of the limiting plate 61 is fixedly connected with a limiting rod 63, the surface of the limiting rod 63 is slidingly connected with a pull plate 64, one end of the pull plate 64 is fixedly connected with a positioning rod 65.

[0030] In the embodiment, the limiting plate 61 can be arranged to limit the counterweight block 2, so as to reduce the situation that the counterweight block 2 is difficult to be limited when the device is used.

[0031] Specifically, the positioning rod 65 is clamped in the inside of the positioning hole 62, the surface of the limiting rod 63 is sleeved with a third spring 66, and the positioning rod 65 is arranged to position the limiting plate 61.

[0032] Specifically, one end of the third spring 66 is fixedly connected with the surface of the pull plate 64, and the other end of the third spring 66 away from the pull plate 64 is fixedly connected with the inside of the limiting plate 61. The third spring 66 is arranged to facilitate the application of a reset elastic force to the pull plate 64.

[0033] Principle: when the device is in use, the user presses the pressing plate 511, which moves the sliding rod 58 and moves the connecting plate 510, which moves the stop rod 57. When the sliding rod 58 moves, the second spring 59 is displaced and deformed to generate a restoring force. The stop rod 57 then moves away from the surface of the stop block 56, pulling the connecting head 4 away from the surface of the connecting column 1. When the connecting head 4 moves, it pulls the ball 53, which moves the first spring 55, which is displaced and deformed to generate a restoring force. The ball 53 then moves away from the inside of the connecting groove 51. The installation device 5 effectively replaces the handle 3, which has the effect of replacing the handle 3. When the device is in use, it is difficult to replace the handle 3 because the device is integrated, making it difficult to adapt to different people's hands and difficult to use comfortably. This installation device 5, through the coordinated action of the ball 53, stop block 56, first spring 55, sliding rod 58, pressing plate 511 and other components, realizes the convenient connection of the connecting head 4 and the connecting column 1, improves the replaceability of the handle 3, and facilitates users to replace the handle 3 according to their own conditions, improves the comfort of the handle 3, and facilitates the adaptive use of different groups of people.

[0034] When the device is in use, the user pulls the pull plate 64, which moves on the surface of the limiting rod 63. When the pull plate 64 moves, it moves the positioning rod 65 out of the positioning hole 62. When the pull plate 64 moves, it displaces and deforms the third spring 66 to generate a restoring force. The auxiliary assembly 6 effectively blocks the counterweight 2, which has the effect of limiting the counterweight 2. When the device is in use, the counterweight 2 is generally connected using bolts, which are difficult to replace quickly, making it difficult to adjust the counterweight 2. This auxiliary assembly 6, through the cooperation of the limiting plate 61, positioning hole 62, pull plate 64, positioning rod 65 and third spring 66, realizes the convenient replacement of the counterweight 2, and can flexibly adjust the weight of the dumbbell according to the actual situation of the user, improving the practicality of the device.
