[0028] like Figure 1 As shown, a high-position pull-down device according to an embodiment of the utility model comprises:
[0029] Base frame 7 and column 2;
[0030] A crossbar 1, one end of which is rotatably connected to the column 2 through a connecting component 4, and the other end of which is connected to a handle 3, so that the handle 3 can swing up and down relative to the column 2 with the connecting component 4 as an axis under the drive of the crossbar 1, and a slide rail 5 is provided on the crossbar 1, and the slide rail 5 is provided at one end close to the connecting component 4;
[0031] A first telescopic rod 6, one end of which is fixed on the base frame 7, and the other end of which is provided with a slider 8, wherein the first telescopic rod 6 is slidably connected to the slide rail 5 via the slider 8, and an electric linear actuator 9 is provided on the first telescopic rod 6 to control the extension and retraction of the first telescopic rod 6 and drive the slider 8 to slide on the slide rail 5, so as to drive the cross bar 1 to swing up and down;
[0032] The controller includes an ascending control key and a descending control key, and is electrically connected to the electric linear actuator 9 to control the operation of the electric linear actuator 9 .
[0033] like Figure 1 As shown, the device described in the present application can realize automatic adjustment of the handle height through the control of the control key. Before the user uses the device for exercise, if the shorter user cannot reach the handle 3, he can directly press and hold the descending control key, and the descending control key controls the operation of the electric linear actuator 9. The operation of the electric linear actuator 9 causes the first telescopic rod 6 to shrink and shorten. The shrinking and shortening of the first telescopic rod 6 drives the slider 8 to move to the left side of the slide rail 5, drives the cross bar 1 to swing downward with the connecting part 4 as the axis, and the cross bar 1 drives the handle 3 to move downward until the handle 3 reaches the desired height position of the user, and then releases the descending control key; when the user wants to adjust the initial training height, he can directly press and hold the ascending control key, and the ascending control key controls the operation of the electric linear actuator 9. The operation of the electric linear actuator 9 causes the first telescopic rod 6 to stretch and lengthen. The lengthening of the first telescopic rod 6 drives the slider 8 to move to the right side of the slide rail 5, drives the cross bar 1 to swing upward with the connecting part 4 as the axis, and drives the handle 3 to move upward until the handle reaches the desired height position of the user. The device described in the utility model allows users of any height to adjust the initial position of the handle to adapt to the training of users of different body shapes.
[0034] The connecting component 4 in the present invention can be any rotating connecting component commonly used in the market, and is not specifically limited in the present application. Preferably, the connecting component 4 is a bearing.
[0035] In an optional embodiment, the device comprises:
[0036] The pull rope 11, the handle 3, the connecting component 4 and the counterweight component are connected through the pull rope 11, so that the handle 3 drives the counterweight component to move up and down when it is raised or pulled down, wherein the counterweight component is arranged in the column 2.
[0037] When doing high pull-down training, the user needs to repeatedly raise and pull down the handle 3. When the handle 3 is raised and pulled down, the pull rope 11 is used to move the weight component arranged in the column 2 up and down, and the weight component can adjust the weight according to the user's strength.
[0038] In an optional embodiment, the device comprises:
[0039] A seat 10 is fixed on the base frame 7;
[0040] The left footrest 12 and the right footrest 13 are arranged in coordination with the seat 10 .
[0041] The device described in the present application can be used in a sitting state as well as a standing state. When the user performs high-position pull-down training while sitting, the user sits on the seat 10, with the left foot on the left foot pedal 12 and the right foot on the right foot pedal 13, so that the user can perform high-position pull-down training more stably.
[0042] In an optional implementation manner, the ascending control key is disposed on the right foot pedal 13 , and the descending control key is disposed on the left foot pedal 12 .
[0043] When the user performs high pull-down training while sitting, he sits on the seat 10 with his feet on the ground and adjusts the height of the handle 3 by stepping on different pedals. The handle 3 is controlled to rise by stepping on the right pedal 13, and the handle 3 is controlled to fall by stepping on the left pedal 12.
[0044] In an optional embodiment, the seat is height-adjustable relative to the base frame.
[0045] The seat 10 described in the utility model has an initial seat height, and the seat 10 can be adjusted in height. Specifically, a second telescopic rod is provided at one end of the base frame 7 connected to the seat 10, and the seat 10 rises or falls driven by the second telescopic rod, and the user can adjust the height of the seat 10 according to his or her height. It can be understood that while the seat 10 is adjustable in height, the handle 3 is also adjustable in height. The manner in which the handle and the seat are both adjustable in height allows the user to train at a suitable height position in a sitting state to achieve the best training effect. Among them, the height of the handle 3 is adjusted by, for example, hand pulling, control key control, and other adjustment methods in the aforementioned embodiment.
[0046] In an optional embodiment, the device also includes a seat armrest 14 fixed on the base frame 7, and the seat 10 is connected and fixed to the base frame 7 via the seat armrest 14. A third telescopic rod is provided at one end of the seat armrest 14 connected to the base frame 7. The seat 10 rises or falls under the drive of the third telescopic rod, and the height of the seat armrest 14 is higher than the position of the seat 10.
[0047] When the user sits on the seat 10, he can sit down by holding the seat armrest 14, which increases safety and avoids the risk of the user falling. No matter whether the user uses the device standing or sitting, he can reach the handle and train at a suitable height position, so that users of various heights can adjust the handle and seat to a height suitable for themselves.
[0048] In an optional implementation, a folding piece is provided between the seat 10 and the seat armrest 14 , so that the seat 10 can be folded relative to the seat armrest 14 .
[0049] When using the device of the utility model, the user can choose to train standing up or sitting down. When choosing to train standing up, the seat 10 is folded to be parallel to the seat armrest 14, and the user can stand up to use the high-position pull-down device, avoiding the seat from hindering the user, so that the user can train in a more comfortable state; when choosing to train sitting down, the seat 10 is unfolded to be perpendicular to the seat armrest 14, and the user can sit down to use the high-position pull-down device. The present application does not limit the specific selection of the folding member, and preferably, the folding member is a hinge.
