Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to a knee pad with a retaining frame. Background Art

[0002] As we all know, knee braces are one of the most common medical auxiliary and protective products for sports injuries. They are mainly used as auxiliary equipment to protect the knee joint from sports injuries or to assist in treatment after sports injuries occur. Current research has also confirmed that the reasonable use of knee braces can significantly reduce the occurrence of sports injuries. The main working principle of knee braces is to promote the coordination of muscles around the knee joint through appropriate pressure compression to enhance the strength of the knee joint and thus reduce the occurrence of sports injuries. In the process of sports injury rehabilitation, knee braces can also protect damaged muscles, ligaments, etc. by coordinating the coordination between muscles and promote tissue healing.

[0003] For example, Chinese utility model patent CN201520664338.7 discloses a medical decompression kneepad anti-fall sleeve, whose main structure is: comprising a kneepad, an alarm device installed on the kneepad, the alarm device is installed in the kneepad, and the induction switch of the alarm device is arranged at the corresponding knee joint of the kneepad; although the above-mentioned kneepad sleeve can squeeze and restrain the patient's knee joint and also has an alarm function, when the user wears it for exercise after knee joint injury or surgery, the above-mentioned kneepad sleeve has no supporting structure, so it cannot play the role of motion buffering and shock absorption for the knee joint during exercise, which makes it not conducive to the rehabilitation of knee joint injury or surgery during exercise, and the user's experience is also poor, and the product grade is low. At the same time, since the middle part of the above-mentioned kneepad sleeve has no anchor point at the knee joint, when the knee joint moves, the two ends of the kneepad sleeve are easy to slide and shorten toward the knee joint, causing the user to need to adjust it frequently, which is inconvenient for the user to actually use. Therefore, the above-mentioned defects are very obvious. For this reason, we propose a kneepad sleeve with a retaining frame to solve the above-mentioned problems. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a knee pad with a retaining frame.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A kneepad with a holder comprises a tubular kneepad body and a holder, wherein two sides of the kneepad body are provided with accommodating cavities along the length direction of the kneepad body and adapted to the holder, the holder comprises a deformation portion, both ends of the deformation portion are connected with ears through a connecting rod, a plurality of V-shaped deformation grooves are provided on the side of the deformation portion, an avoidance groove connected to the deformation groove is provided on the deformation portion, and a positioning groove adapted to the patella of the knee joint is provided in the middle of the inner wall of the kneepad body; wherein, when a user wears the kneepad body at the knee joint for exercise, the deformation portion is squeezed by an external force so that the width of the deformation groove is reduced, thereby causing the deformation portion to bend and deform, and the bending stops when the opposite side walls of the deformation groove are squeezed and fitted.

[0007] Preferably, a steel wire rope is embedded inside the retaining frame and along its length direction.

[0008] Preferably, an avoidance hole is opened on the ear piece, and the ear piece is welded or sewn in the accommodating cavity by hot pressing.

[0009] Preferably, the fabric on the surface of the kneepad body covers the opening of the accommodating cavity.

[0010] Preferably, the deformation portion is made of a deformable material.

[0011] Preferably, the retaining frame is made of plastic injection molding.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, due to the adoption of the above scheme, the main features of the utility model are that the retaining frames are embedded on both sides of the knee pad body, the ear pieces at both ends of the retaining frames are fixed to the two ends of the knee pad body, and the sides of the deformation part are provided with a plurality of V-shaped deformation grooves. Therefore, when the knee joint moves, the deformation part is squeezed by the external pressure force, so that the width of the deformation groove is reduced, the deformation part bends and deforms, and generates an opposite force on the knee joint, thereby generating movement buffering when the knee joint bends. When the opposite side walls of the deformation groove are squeezed and fitted, the deformation part stops bending. When the knee joint moves in the opposite direction and straightens, the deformation part generates an elastic force for automatic reset, which helps the knee joint to straighten in the opposite direction. Therefore, when the knee joint is in motion, the utility model can play a role in movement buffering and limiting bending, effectively reducing the load on the knee joint during motion, making the knee joint move more easily, which is beneficial to the rehabilitation of the knee joint after injury or surgery, improving the user experience, and improving the product grade.

[0013] Furthermore, when the knee joint is wearing the knee pad body, the patella of the knee joint is placed in the positioning groove, so that the middle part of the knee pad body has an anchor point at the knee joint, and the two ends of the retaining frame support the two ends of the knee pad body, so when the knee joint moves, the two ends of the knee pad body are not easy to slide or shorten, which is convenient for users to actually use. At the same time, when exercising, the patella of the knee joint is placed in the positioning groove, which can effectively limit the patella of the knee joint, reduce the vibration of the patella of the knee joint during exercise, play a buffering and shock-absorbing role, and ensure the stability of the patella. Therefore, it has multiple practical functions, which greatly meets the actual use needs of users. It has a simple structure, is easy to use, and has strong practicality.

[0021] like Figure 1 to Figure 2 As shown, a kneepad with a retainer provided in this embodiment comprises a cylindrical kneepad body 1 and a retainer 2. Both sides of the kneepad body 1 are provided with a receiving cavity 3 along the length direction of the kneepad body 1 and adapted to the retainer 2. The retainer 2 comprises a deformation portion 4. Both ends of the deformation portion 4 are connected with ear pieces 6 through connecting rods 5. The side of the deformation portion 4 is provided with a plurality of V-shaped deformation grooves 7. The opening of the deformation groove 7 is large and the opening of the other end is small, so the whole is V-shaped, which is more conducive to the shrinkage of the deformation groove 7 when the deformation portion 4 is bent. The deformation portion 4 is provided with a plurality of V-shaped deformation grooves 7. 7 is connected to the avoidance groove 8. When the deformation part 4 bends, the width of the deformation groove 7 is reduced, and the material in the avoidance groove 8 is compressed and deformed. In fact, the deformation groove 7 and the avoidance groove 8 are connected so that the deformation part 4 forms a plurality of springs in a "X" shape. The middle part of the inner wall of the knee pad body 1 is provided with a positioning groove 11 adapted to the patella 10 of the knee joint 9; wherein, when the user wears the knee pad body 1 at the knee joint 9 for exercise, the deformation part 4 is squeezed by external force so that the width of the deformation groove 7 is reduced, thereby causing the deformation part 4 to bend and deform, and the bending stops when the opposite side walls of the deformation groove 7 are squeezed and fitted.

[0022] In actual use of this embodiment, when the knee joint 9 moves, the deformation portion 4 is squeezed by the external pressure force so that the width of the deformation groove 7 is reduced, and the deformation portion 4 bends and deforms and generates an opposite force on the knee joint 9, thereby generating movement buffer when the knee joint 9 bends. When the opposite side walls of the deformation groove 7 are squeezed and fitted, the deformation portion 4 stops bending. When the knee joint 9 moves in the opposite direction and straightens, the deformation portion 4 generates an elastic force for automatic reset to help the knee joint 9 to straighten in the opposite direction. Therefore, when the knee joint 9 is in motion, this device can play a role in movement buffering and limiting bending, effectively reducing the load on the knee joint 9 during movement, making the knee joint 9 move more easily, which is beneficial to the knee joint 9 after injury or surgery. Rehabilitation, improve user experience, and improve product grade; and, when the knee joint 9 wears the knee brace body 1, the patella 10 of the knee joint 9 is placed in the positioning groove 11, so that the middle part of the knee brace body 1 has an anchor point at the knee joint 9, and the two ends of the retaining frame 2 support the two ends of the knee brace body 1, so when the knee joint 9 moves, the two ends of the knee brace body 1 are not easy to slide or shorten, which is convenient for users to use. At the same time, when exercising, the patella 10 of the knee joint 9 is placed in the positioning groove 11, which can effectively limit the patella 10 of the knee joint 9, reduce the vibration of the patella 10 of the knee joint 9 during exercise, play a buffering and shock-absorbing role, and ensure the stability of the patella 10. Therefore, it has multiple practical functions, greatly meets the actual use needs of users, has a simple structure, is easy to use, and has strong practicality.

[0023] Furthermore, the interior of the retainer 2 of this embodiment and along its length direction are embedded with a steel wire rope 12. The steel wire rope 12 is highly flexible and easily deformed, but has high tensile strength, so embedding the steel wire rope 12 in the retainer 2 effectively improves the overall compressive strength of the retainer 2, thereby preventing the retainer 2 from permanent deformation or breakage after long-term use, thereby improving the overall service life.

[0024] Furthermore, the ear piece 6 of this embodiment is provided with an avoidance hole 13, and the ear piece 6 is welded or sewn in the accommodating cavity 3 by hot pressing. When the ear piece 6 is hot pressed and welded, the fabric on the surface of the kneepad body 1 is passed through the avoidance hole 13 and welded to the inner wall of the accommodating cavity 3, which effectively improves the fixing strength of the ear piece 6; when the ear piece 6 is sewn, the needle and thread can also pass through the avoidance hole 13 and sew on the inner wall of the accommodating cavity 3, which effectively improves the fixing stability of the ear piece 6, thereby improving the connection strength and stability between the two ends of the retaining frame 2 and the kneepad body 1.

[0025] Furthermore, the fabric on the surface of the kneepad body 1 of this embodiment covers the opening of the accommodating cavity 3. Therefore, the above design effectively shields the retaining frame 2 in the accommodating cavity 3, improves the overall appearance, and can also effectively limit the retaining frame 2 in the accommodating cavity 3.

[0026] Furthermore, the deformation part 4 of this embodiment is made of a deformable material. For example, the deformation part 4 is made of rubber or spring steel, which is easy to deform and return to its original shape after being subjected to force. The characteristics of the above materials meet the preferred material use of the deformation part 4.

[0027] Furthermore, the holder 2 of this embodiment is made of plastic injection molding. Plastic is light in weight and low in hardness, and is not easy to wear the braid of the knee pad body 1. At the same time, the holder 2 can be mass-produced by mold injection molding, thereby reducing the overall production cost.

[0028] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
