Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a lower limb exercise rehabilitation device. Background Art

[0002] The knee joint needs to be effectively exercised during the rehabilitation period after injury or medical surgery. Appropriate and effective rehabilitation exercises for the knee joint are very important for restoring the function of the knee joint. In the prior art, the announcement number CN219071974U discloses a portable lower limb sports injury rehabilitation training device. When the device is in use, the concave clamp is screwed with the positioning bolt to fix the device on the bed frame. However, in order to avoid accidental injuries, the bed frame used in the rehabilitation center is generally cylindrical, which makes the contact area between the positioning bolt and the bed frame smaller. In daily use, this rehabilitation device may be offset. Utility Model Content

Since the sides of the two symmetrically arranged groups of splints close to each other are both arc surfaces, the splints and the cylindrical bed frame guardrail are more fitted and the contact area is larger, which improves the stability of the main body of the device during use to a certain extent.

[0008] Preferably, a screw head is fixedly connected to one side of the bidirectional screw rod located outside the concave clamp.

[0027] The utility model provides a lower limb exercise rehabilitation device through improvement. The technical solution of the utility model is:

[0028] like Figure 1-Figure 4 As shown, a lower limb exercise rehabilitation device includes a shell 1, a concave clamp 2 is fixedly connected to the bottom of the shell 1 through a connecting rod, a threaded component 3 is rotatably connected to the side wall of the concave clamp 2, a threaded plate 4 is symmetrically threadedly connected to the threaded component 3, a support rod 5 is symmetrically fixedly connected to the side where two groups of threaded plates 4 are close to each other, a clamping plate 6 is symmetrically fixedly connected to the side where two groups of support rods 5 are close to each other, a limiting rod 7 is symmetrically fixedly connected to the inner cavity of the concave clamp 2, and the threaded plate 4 is slidably set on the limiting rod 7, a mounting frame 8 is fixedly connected to the side wall of the concave clamp 2, and constraint components 9 that are mutually engaged with the threaded component 3 are symmetrically slidably set on the side walls at both ends of the inner side of the mounting frame 8, and baffles 10 are symmetrically rotatably connected to the two ends of the mounting frame 8, a resistance bearing 11 is set in the groove at the top of the shell 1, and pedals 12 are connected to both ends of the resistance bearing 11.

[0029] Furthermore, the threaded assembly 3 includes a bidirectional screw rod 31 rotatably connected to the side wall of the concave clamp 2, and a toothed plate 32 is fixedly connected to the rod body of the bidirectional screw rod 31. When the staff turns the bidirectional screw rod 31, the two symmetrically arranged groups of threaded plates 4 move toward each other along the thread direction of the bidirectional screw rod 31, and the arranged threaded plates 4 drive the support rods 5 to slide, and the arranged support rods 5 drive the clamping plates 6 to move. The two symmetrically arranged groups of clamping plates 6 are clamped on both sides of the guardrail part of the bed frame. This device fixes the device body on the guardrail part of the bed frame with the help of the clamping plates 6. Since the sides of the two symmetrically arranged groups of clamping plates 6 that are close to each other are both arc surfaces, the clamping plates 6 and the cylindrical bed frame guardrail are more fitted and the contact area is larger, which improves the stability of the device body during use to a certain extent.

[0030] Among them, a screw head 13 is fixedly connected to one side of the bidirectional screw rod 31 located outside the concave clamp 2, and the screw head 13 is provided to facilitate medical staff to turn the bidirectional screw rod 31 to slide.

[0032] A limiting groove 14 is provided on the side wall of the pull plate 94 , and the baffle 10 is arranged to be snapped into the limiting groove 14 to ensure the stability of the baffle 10 when in use.

[0035] Then the staff turns over the baffle 10 so that the baffle 10 is clamped on the pull plate 94, and the baffle 10 is used to prevent the tooth block 95 from rebounding under the action of the elastic force of the spring 93;

[0036] Then the staff member turns the bidirectional screw rod 31, and the two symmetrically arranged groups of threaded plates 4 move toward each other along the thread direction of the bidirectional screw rod 31, and the arranged threaded plates 4 drive the support rod 5 to slide, and the arranged support rod 5 drives the clamping plate 6 to move, and the two symmetrically arranged groups of clamping plates 6 are clamped on both sides of the bed frame guardrail part. This device fixes the device body on the guardrail part of the bed frame with the help of the clamping plates 6. Since the two symmetrically arranged groups of clamping plates 6 are close to each other on both sides, the clamping plates 6 and the cylindrical bed frame guardrail are more closely fitted and the contact area is larger, which improves the stability of the device body when in use to a certain extent;

[0037] Then the staff flips over the baffle 10 to release the limit of the baffle 10 on the pull plate 94, and then the tooth block 95 re-engages with the tooth plate 32 under the action of the elastic force of the spring 93 to restore the limit fixation of the two-way screw rod 31 by the tooth block 95; this device uses the tooth block 95 to limit and fix the two-way screw rod 31, making it difficult for the two-way screw rod 31 to loosen, which further improves the stability of the device body during use.
