Description

Technical Field

[0001] This utility model relates to the field of leg exercise equipment technology, and in particular to a leg rehabilitation device for nursing. Background Technology

[0002] When the leg is injured by external force, recovery is achieved through surgery, immobilization, and rest. However, when the leg is kept in a fixed position for a long time, the muscles and nerves are prone to stiffness, which affects normal walking. Rehabilitation training is often necessary. Currently, most common training methods involve walking training. However, in the early stages of recovery, due to decreased balance and strength, the leg cannot train on its own and often requires assistance. At the same time, the need to support body weight during training can easily lead to secondary leg injuries and cannot effectively train the knee joint. Therefore, there is an urgent need for a device suitable for early leg rehabilitation training. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a leg rehabilitation device for nursing care, which addresses the above-mentioned technical deficiencies. In the initial training, the leg can move directly by stepping on the slide without the help of others. At the same time, the body does not need to bear the weight during training, avoiding secondary injury. Moreover, the resistance of the foot can be adjusted to suit different recovery stages.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model includes:

[0005] The housing has brake components symmetrically arranged on both sides of the front of the housing, and a guide wheel assembly is provided on the inner side of the brake components on the housing.

[0006] The slide is slidably connected to the rear of the housing. The slide is symmetrically provided with ropes, which are connected to the brake components via guide wheel assembly.

[0007] Preferably, the braking component includes a drum and a bracket; the drum is connected to the housing by a rotating shaft, and a friction disc is provided above the drum; the bracket is fixed to the housing, a thrust component is provided on the bracket, and a stop component is provided on the push rod of the thrust component.

[0008] Preferably, the stop member has a friction strip with an arc-shaped working surface on one side.

[0009] Preferably, the thrust member is provided with a support plate; the left side of the stop member is symmetrically provided with guide posts that penetrate the support plate, and a support spring is sleeved on the guide post.

[0010] Preferably, a first pulley is provided below the drum; a reset motor is installed on the housing, and the reset motor is connected to the first pulley via a belt.

[0011] Preferably, a sliding column is provided at the rear of the housing, and positioning rails are provided on the side walls of the housing on both sides of the sliding column.

[0012] Preferably, the initial end of the sliding column is provided with a buffer pad.

[0013] Preferably, a footboard is provided above the carriage.

[0014] Preferably, the end cap of the housing is provided with size scale lines.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. Personnel can directly move by stepping on the slide frame and use resistance support to effectively train leg strength and knee joints without bearing their own body weight, thus avoiding secondary injuries caused by excessive force. At the same time, the resistance can be adjusted according to the recovery stage by relying on the braking device, making it suitable for different recovery situations and more flexible in use.

[0017] 2. The carriage and braking components are connected by a rope, which can meet the foot pedal requirements of different strokes. At the same time, the guide wheel group supports the rope, ensuring the stability of the structure and avoiding rope wear, thus extending the service life of the rope.

[0018] 3. The braking components are arranged in pairs and connected to both sides of the carriage by ropes, which can ensure the stability of the force on both sides during the carriage displacement and avoid excessive wear.

[0019] 4. The thrust component pushes the friction strip into contact with the outer circle of the friction disc, using friction to create resistance during pedaling. At the same time, the magnitude of the pressure generated by the thrust component can be used to adjust the resistance. The structure is simple and convenient. The sliding connection between the stop component and the support plate can use the elasticity of the support spring to increase the range of force adjustment, making it more practical and reliable.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0029] Specific implementation method one: Combining Figure 1-7 As shown, a leg rehabilitation device for nursing care includes: a housing 1, with brakes 2 symmetrically arranged on both sides of the front of the housing 1, and a guide wheel assembly 3 located on the inner side of the brakes 2 on the housing 1; a slide 4, which is slidably connected to the rear of the housing 1, with ropes 401 symmetrically arranged on the slide 4, the ropes 401 forming a guide support through the guide wheel assembly 3, and the other end connected to the brakes 2;

[0030] The braking element 2 generates resistance, tilting the entire device at a certain angle or placing it flat. The user moves the slide 4 with one foot, and the rope 401 pulls the braking element 2 to rotate, overcoming the resistance and achieving leg training. During the pedaling process, the knee joint can bend to a greater extent, achieving simultaneous training of strength and knee joint. It is safe and reliable. Furthermore, depending on the recovery stage, the resistance of the braking element 2 can be adjusted to create different levels of resistance, making it widely applicable. After initial training, the user can avoid injury when practicing walking, making it more reasonable and effective.

[0031] Preferred embodiments, in combination Figure 4-6As shown, the braking component 2 includes a drum 5 and a bracket 6. The drum 5 is connected to the housing 1 by a rotating shaft. A friction disc 501 is installed above the drum 5. The bracket 6 is fixed to the housing 1 by screws and is located near the friction disc 501. At the same time, a thrust component 601 is installed above the bracket 6. The thrust component 601 adopts a hydraulic cylinder or an electric push rod. A stop component 602 is provided on the push rod of the thrust component 601. The thrust component 601 pushes the stop component 602 to contact the friction disc 501 to generate friction force, thereby realizing braking resistance. At the same time, the resistance can be adjusted by controlling the magnitude of the thrust.

[0032] Preferred embodiments, in combination Figure 6 As shown, a friction strip 603 with an arc-shaped working surface is installed on one side of the stop 602. The friction strip 603 is made of rubber material, which has good wear resistance, and the arc-shaped surface can increase the contact area with the friction disc 501 and enhance the braking effect.

[0033] Preferred embodiments, in combination Figure 5 and Figure 6 As shown, the thrust member 601 is provided with a support plate 604; the other side of the stop member 602 is symmetrically provided with a guide post 605 that penetrates the support plate 604, and a support spring 606 is sleeved on the guide post 605. During the process of pushing the friction strip to contact the friction disc, the compression of the support spring can effectively increase the adjustment range of the braking force and enhance usability.

[0034] Preferred embodiments, in combination Figure 4 and Figure 5 As shown, a first pulley 502 is provided below the drum 5; a reset motor 101 is installed on the housing 1. The reset motor 101 is connected to the first pulley 502 via a belt. The reset motor 101 drives the first pulley 502 to rotate, thereby realizing the winding operation of the drum 5 on the rope 401 and completing the reset action of the slide 4. During the reset process, the friction strip 603 preferentially disengages from the friction disc 501 to reduce the reset resistance.

[0035] Preferred embodiments, in combination Figure 2 , Figure 3 and Figure 7 As shown, a sliding column 102 is provided at the rear of the housing 1, and positioning rails 103 are provided on the side walls of the housing 1 on both sides of the sliding column 102. The positioning rails 103 provide support and guidance for the carriage 4.

[0036] Preferred embodiments, in combination Figure 3 As shown, a buffer pad 104 is bonded to the initial end of the slide column 102. The buffer pad 104 is made of natural rubber. During reset, it prevents the slide 4 from directly colliding with the housing 1, reduces the impact force, and plays a protective role.

[0037] Preferred embodiments, in combination Figure 7 As shown, a foot pedal 402 is provided above the carriage 4, providing a position for the user's feet to bear weight.

[0038] Preferred embodiments, in combination Figure 1 As shown, the end cover of the housing 1 is provided with a size scale line 105, which makes it convenient for the user to judge whether the leg is fully extended during the pedaling process. Specific Implementation Method Two

[0040] Combination Figure 3 and Figure 7 As shown, the sliding columns 102 can be arranged in pairs, and two through holes are opened on the carriage 4 accordingly. The through holes are connected to the sliding columns 102 to realize the guiding support of the carriage 4 and also meet the displacement requirements of the carriage 4. Specific Implementation Method 3

[0042] Combination Figure 2 As shown, for braking the friction disc 501, two sets of brackets 6 can be arranged. When a larger resistance is required, the friction strip 603 is pushed to contact the friction disc 501 simultaneously by two thrust members 601. By controlling the thrust of the two thrust members 601, different resistance levels can be generated, further improving the range of resistance adjustment and making it convenient to use.

[0043] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
