Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of rehabilitation training appliance, concretely relates to a dumbbell with adjustable weight for rehabilitation training. BACKGROUND

[0002] Heart failure, in short, heart failure, is due to the systolic function and diastolic function of the heart, and the heart cannot fully discharge the volume of blood back to the heart, resulting in venous system blood stasis, and arterial system blood perfusion is insufficient, thereby causing heart failure syndrome, which is mainly manifested as pulmonary congestion and venous congestion. Heart failure patients need to do some aerobic exercise after rehabilitation treatment to ensure that heart failure can be cured as soon as possible. During the treatment process, doctors often prescribe exercise for patients. Common exercise prescriptions include running training, treadmill training and dumbbell training. The traditional dumbbell is relatively common when changing the weight piece. The general dumbbell changes the weight piece by fixing the weight piece with a clip or a nut. When the weight piece is fixed by the clip, the clip needs to be tightly attached to the weight piece. However, if the clip is not tightly attached to the weight piece, the weight piece will move, affecting the use of the dumbbell. When changing the weight piece, the clip or nut needs to be removed first, then the number of weight pieces needs to be adjusted to adjust the weight of the dumbbell, and then the clip or nut is installed to limit and fix the weight piece. This kind of weight adjustment method is complicated, and heart failure patients need to monitor heart rate during rehabilitation training. However, the traditional dumbbell does not have this function. Therefore, we propose a dumbbell that can monitor heart rate and adjust weight conveniently. CONTENT

[0003] The utility model aims at providing a dumbbell with adjustable weight for rehabilitation training, which aims to solve the problems in the background art.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a dumbbell with adjustable weight for rehabilitation training, comprising a handle, both ends of the handle are provided with a limiting disc, the surface of the handle is provided with a hand-held heart rate acquisition sheet, the side surface of the limiting disc is fixedly installed with a plug rod, the surface of the limiting disc is installed with a first limiting block on both sides of the plug rod, the surface of the plug rod is installed with a weight piece, the middle part of the weight piece is provided with a plug hole, the plug rod and the plug hole are connected by inserting, one side of the weight piece is installed with two limiting grooves, the other side of the weight piece is installed with two second limiting blocks, the limiting grooves and the second limiting blocks are located on both sides of the plug hole, the surface of the weight piece is provided with a pull groove, the weight piece is provided with a limiting assembly, and the weight piece and the limiting disc are fixed by the limiting assembly and the first limiting block, and the adjacent weight pieces are fixed by the limiting assembly and the second limiting block.

[0005] As a preferred technical solution of this utility model, the limiting component includes two strip grooves opened inside the counterweight plate. The top and bottom of the two strip grooves respectively pass through the pull groove and the corresponding limiting groove. A limiting rod is inserted and connected in the strip groove. One end of the limiting rod extends into the pull groove and is fixedly connected to the handle. A spring is installed between the bottom of the handle and the pull groove.

[0006] As a preferred technical solution of this utility model, both the first limiting block and the second limiting block have limiting holes on their surfaces, and the size of the limiting holes matches the size of the limiting rod.

[0007] As a preferred technical solution of this utility model, when the counterweight plate is attached to the limiting plate, the first limiting block is fully inserted into the corresponding limiting groove and the limiting rod is aligned with the limiting hole on the surface of the first limiting block.

[0008] As a preferred technical solution of this utility model, when adjacent counterweights are attached, the second limiting block is fully inserted into the corresponding limiting groove and the limiting rod is aligned with the limiting hole on the surface of the second limiting block.

[0009] As a preferred technical solution of this utility model, the grip bar has an internal mounting cavity, in which a microcontroller and a battery compartment are installed. The battery compartment contains a removable rechargeable battery and is electrically connected to the microcontroller. The hand-held heart rate sensor is also electrically connected to the microcontroller.

[0010] As a preferred technical solution of this utility model, the microcontroller has wireless data transmission and reception functions.

[0011] As a preferred technical solution of this utility model, the bottom end of the grip bar is provided with a maintenance hole that penetrates the mounting cavity. The maintenance hole is directly opposite the battery compartment, and a cover plate is detachably installed in the maintenance hole by screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the limiting component, changing the counterweight plate only requires the patient to lift the handle upward to raise the limiting rod, and then the first limiting block and the second limiting block set to fix the counterweight plate conveniently and quickly. Compared with the dumbbell in the prior art, this fixing method has the advantage of more convenient weight adjustment. When the patient holds the bar for rehabilitation exercises, the hand-held heart rate acquisition plate can collect the patient's heart rate in real time, and the heart rate information will be processed by the microcontroller and sent to the mobile terminal through the wireless data transceiver device.
