[0001] The present invention belongs to the technical field of rehabilitation training devices, and specifically relates to a child anti-fall rehabilitation training device. Background Art

[0002] Rehabilitation training devices are equipment used to help patients restore their physical functions, mainly applied to functional impairments caused by diseases, surgeries or injuries. Currently, the conventional rehabilitation training devices for children generally adopt a bracket structure. As shown in Figure 1 the figure, that is, holding the bracket by hand, the patient holds the handle at the upper part of the bracket, and under the cooperation of the bracket, moves forward slowly, thereby realizing the rehabilitation training of the legs. Some products also have walking wheels configured at the bottom of the bracket, and the application principle is the same. However, in the existing bracket-type rehabilitation training devices, during the use process, the balance performance of the device is poor, especially for children, which may cause the device to easily tip over during the rehabilitation training process, not only affecting the rehabilitation training effect, but also easily causing secondary injuries to the patients. Summary of the Invention

[0003] The purpose of the present invention is to provide a child anti-fall rehabilitation training device to solve the technical problems existing in the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A child anti-fall rehabilitation training device includes a bracket main body. The bracket main body includes a U-shaped frame at the upper part, a support column vertically arranged at the lower end of the U-shaped frame, a bottom support rod arranged at the bottom end of the support column, and a walking wheel arranged at the lower end of the bottom support rod. At the bottom end of the bracket main body and outside the walking wheel, a pop-up support mechanism is arranged. The pop-up support mechanism includes a piston groove arranged at the bottom end of the bracket main body, a spring arranged at one end of the piston groove, a piston rod arranged at the other end of the piston groove and inserted into the piston groove, a connecting part arranged at the end of the piston rod, a support foot arranged at the lower end of the connecting part, and an electric telescopic control mechanism for controlling the release of the spring; at the upper part of the bracket main body, a control panel is arranged. At the middle part of the upper end of the control panel, a fixed shaft is arranged, and a rotating rod that can rotate relative to it is sleeved on the fixed shaft. At the lower end of the rotating rod, a counterweight block for driving the rotation of the rotating rod is arranged. On the control panel, control switches for controlling the electric telescopic control mechanism are symmetrically arranged on both sides of the counterweight block, and the control switches are triggered by the counterweight block.

[0005] In one embodiment, the piston groove of the pop-up support mechanism located at the rear end of the bracket body is arranged on the bottom support rod at the rear end; an extension support rod is arranged on the outer side of the front end of the bracket body, and the piston groove of the pop-up support mechanism located at the front end of the bracket body is arranged on the extension support rod.

[0006] In one embodiment, the electric telescopic control mechanism includes an electric telescopic rod, a blocking strip arranged at the end of the electric telescopic rod, and a clamping groove cooperating with the blocking strip is arranged on the upper end surface of the piston rod near one end of the spring.

[0007] In one embodiment, under normal state, the spring is compressed, the blocking strip is inserted into the piston groove and its end is inserted into the clamping groove, and the piston rod is retracted into the piston groove.

[0008] In one embodiment, in the pop-up state, the spring returns to its natural state, the end of the blocking strip disengages from the clamping groove, and the piston rod pops out relative to the piston groove.

[0009] In one embodiment, a slider slidable relative to it is further arranged in the piston groove, and one end of the slider is connected to the side wall of the piston rod.

[0010] In one embodiment, strengthening cross frames are arranged at the front end and both sides of the bracket body.

[0011] In one embodiment, two strengthening cross frames are arranged between the two support columns at the front end of the bracket body, and the control panel is arranged between the two strengthening cross frames.

[0012] In one embodiment, under normal state, the traveling wheels abut against the ground and the support feet are off the ground.

[0013] In one embodiment, the included angle between the support feet and the connecting part is 90° - 145°.

[0014] Compared with the prior art, the present invention has the following beneficial effects: According to the present invention, based on the structure of the bracket main body, a rotating rod, a counterweight block, and a control switch are provided thereon, and a pop-up support mechanism is provided outside the walking wheels. When the user uses the device and tilts to one side, under the action of the counterweight block, the rotating rod rotates around the fixed shaft, so that the side wall of the counterweight block triggers the control switch. The electric telescopic control mechanism is activated and changes from the extended state to the retracted state, thereby driving the blocking strip to disengage from the card slot. The spring returns from the compressed state and quickly pops the piston rod out of the piston slot, thereby driving the support feet to pop out. The support feet abut against the ground and play a supporting role. On the one hand, it can effectively prevent the equipment from tipping over. On the other hand, under normal conditions, the support feet are in a retracted state and off the ground, and do not affect the normal rehabilitation training use of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to enable those skilled in the art to have a clearer understanding and knowledge of the present invention, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described below are only used to explain the present invention for easy understanding. The technical solutions provided by the present invention are not limited to the technical solutions provided by the following embodiments, and the technical solutions provided by the embodiments should not limit the protection scope of the present invention.

[0023] Embodiment As Figures 2 to 6 shown, this embodiment provides a child anti-fall rehabilitation training device, which includes a bracket main body. The structure of the bracket main body can adopt an existing mature structure. The bracket main body can be made of hollow stainless steel material. On the one hand, it has good strength. On the other hand, when it comes to wire routing and connection, hidden wiring can be realized based on the hollow steel pipe, which belongs to existing conventional technical means, so it will not be elaborated here.

[0024] In this embodiment, the bracket main body includes a U-shaped frame located at the upper part, a support column vertically arranged at the lower end of the U-shaped frame, a bottom support rod arranged at the bottom end of the support column, and a walking wheel arranged at the lower end of the bottom support rod. When in use, the human body is located inside the bracket, that is, inside the U-shaped frame. Handrails can also be arranged at the upper ends of both sides of the U-shaped frame for easy use; there are four support columns. Based on the U-shaped frame, the four support columns are respectively located at the four corners of the bracket main body, with two at the rear and two at the front; the bottom support rod is located at the rear end of the bottom of the bracket main body and is fixedly connected to the lower ends of the two rear support columns, such as by welding; on both sides of the bottom end of the bracket main body are bottom support crossbars. One end of the bottom support crossbar is fixedly connected to the bottom support rod, and the other end is fixedly connected to the lower ends of the two front support columns, such as by welding; there are four walking wheels, which are respectively arranged at the four corners of the bracket main body, with two at the rear and two at the front. The front walking wheels are arranged at the lower end of the bottom support crossbar, and the rear walking wheels are arranged at the lower end of the bottom support rod. The walking wheels can adopt conventional walking wheel types such as universal wheels and single-direction wheels.

[0025] On the basis of the above structure, in this embodiment, a pop-up support mechanism is arranged outside the walking wheels at the bottom end of the bracket main body. The pop-up support mechanism includes a piston groove arranged at the bottom end of the bracket main body. Due to the different positions of the front and rear ends of the bracket main body, the above setting methods are different, specifically as follows: The piston groove of the pop-up support mechanism at the rear end of the bracket main body is arranged on the rear bottom support rod; an extension support rod is arranged outside the front end of the bracket main body, and the piston groove of the pop-up support mechanism at the front end of the bracket main body is arranged on the extension support rod; wherein, one end of the extension support rod is fixedly connected to the bottom support crossbar, such as by welding.

[0026] One end of the piston groove is open. Specifically, the end of the piston groove facing the outer end of the traveling wheel is open, and a spring is provided at the end of the piston groove opposite to this end. A piston rod is inserted through the open end of the piston groove, and the piston rod can perform telescopic movements relative to the piston groove. To facilitate the telescopic movement of the piston rod relative to the piston groove, a slider that can slide relative to it is also provided in the piston groove in this embodiment, and one end of the slider is connected to the side wall of the piston rod. Thus, the telescopic movement of the piston rod relative to the piston groove will be smoother.

[0027] In this embodiment, a connecting portion integrally formed with it is provided at one end of the piston rod. The connecting portion generally has the same external contour shape as the piston rod. The spring is located between the other end of the piston rod and the end of the piston groove, and one end of the spring is fixedly connected to the inner wall of the end of the piston groove, and the other end is fixedly connected to the other end of the piston rod. A support foot integrally formed with it is provided at the lower end of the connecting portion, and an anti-slip pad can be provided at the bottom of the support foot. Under normal conditions (that is, when the pop-up support mechanism is in a contracted state), the traveling wheel abuts against the ground and the support foot is off the ground. In a preferred solution, the angle between the support foot and the connecting portion is 90° - 145°, such as angles of 90°, 120°, etc. Based on the above settings, the support foot can play a better supporting role. At the same time, in the contracted state, the support foot being off the ground does not affect the normal use of the rehabilitation training device.

[0028] Under normal conditions, the spring is in a compressed state, and the control of the spring release is achieved through an electric telescopic control mechanism. The electric telescopic control mechanism includes an electric telescopic rod, a blocking strip provided at the end of the electric telescopic rod. The electric telescopic rod is fixed to the bottom support rod / extended support rod through a fixed connecting rod. The lower end of the fixed connecting rod is fixed to the bottom support rod / extended support rod, and the upper end is fixedly connected to the upper end of the electric telescopic rod. At the same time, a card slot cooperating with the blocking strip is provided on the upper end surface of the piston rod near one end of the spring. The blocking strip is inserted into the piston groove. For the piston groove on the bottom support rod, in order to enable the blocking strip to be inserted into the piston groove, a hole matching the size of the blocking strip is provided on the bottom support rod. The cross-sectional size of this hole should match the card slot on the piston rod, and when the spring is in a compressed state, this hole corresponds to the card slot on the piston rod so that the blocking strip can be inserted into the piston groove and the card slot. For the piston groove on the extended support rod, in order to enable the blocking strip to be inserted into the piston groove, a hole matching the size of the blocking strip is provided on the extended support rod. The cross-sectional size of this hole should match the card slot on the piston rod, and when the spring is in a compressed state, this hole corresponds to the card slot on the piston rod so that the blocking strip can be inserted into the piston groove and the card slot. In the pop-up state, the spring returns to its natural state, the end of the blocking strip disengages from the card slot, and the piston rod pops out relative to the piston groove.

[0029] When the human body uses the device, the operation of the electric telescopic control mechanism is triggered by whether the device tilts sideways. The implementation structure is as follows: A control panel is provided at the upper part of the bracket body. A fixed shaft is provided in the middle of the upper end of the control panel. A rotating rod that can rotate relative to it is sleeved on the fixed shaft. A counterweight is provided at the lower end of the rotating rod to drive the rotation of the rotating rod. Control switches for controlling the electric telescopic control mechanism are symmetrically arranged on both sides of the counterweight on the control panel, and the control switches are triggered by the counterweight. Among them, a battery can be built into the control panel for power supply. The control switches and the electric telescopic rod are electrically connected, which can be wirelessly connected or wired connected. If it involves wired connection, hidden wiring can be used. The type of the control switch can be a push-button switch, and it faces the direction of the counterweight, so that when the device tilts sideways, the counterweight can touch and press the control switch. To improve the support strength of the bracket body, in this embodiment, strengthening cross frames are provided at the front end and both sides of the bracket body. Moreover, two strengthening cross frames are provided between the two support columns at the front end of the bracket body. Based on the setting of the strengthening cross frames, the control panel is arranged between the two strengthening cross frames, and the connection method between the two can adopt conventional fixed connection methods such as bolt connection and welding.

[0030] The implementation principle of the above structure is as follows: When using this device and the device tilts sideways, when the user uses this device and tilts sideways, under the action of the counterweight, the rotating rod rotates around the fixed shaft, so that the side wall of the counterweight triggers the control switch, and the electric telescopic control mechanism starts and changes from the extended state to the contracted state. Thereby driving the blocking strip to disengage from the card slot, the spring returns from the compressed state, and quickly pops the piston rod out of the piston slot, thereby driving the support foot to pop out. The support foot abuts against the ground and plays a supporting role. At this time, this device is in the popped state, thereby preventing the device from tipping over. When the device returns to the normal state, the traveling wheels touch the ground, the support feet leave the ground, press the support feet towards the direction of the traveling wheels, the spring is compressed, when the piston rod contracts to the end, the card slot on the piston rod corresponds to the hole on the bottom support rod / bottom support cross bar. At this time, press the control switch again by hand, the electric telescopic rod extends, driving the blocking strip to insert into the card slot, and the piston rod is stuck. At this time, this device returns to the normal state.

[0031] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
