Technical Field
[0001] The utility model relates to the technical field of human body protectors, in particular to an inflatable sports knee pad. Background Art
[0002] The knee joint is an important joint of the human body. It not only bears the weight of the body but also maintains the movement of the limbs. Compared with other joints, it bears more weight and is more vulnerable. A knee pad is an item used to protect people's knee joints. During exercise, wearing a knee pad plays a role in protection and correction. On the one hand, it can reduce the damage to the knee joint caused by external impact force, and on the other hand, it can limit the movement of the knee joint to a certain extent to prevent problems with the knee joint itself.
[0003] Common knee pads are mostly one-piece knee pads, and the inside is filled with silica gel or sponge for shock absorption and protection. Such sports knee pads can play a good fixing role for the joints, but if the silica gel or sponge material wants to achieve a better shock absorption effect, its thickness needs to be increased. Therefore, such sports knee pads are mostly bulky and have poor air permeability.
[0004] Nowadays, there are also some inflatable sports knee pads, and air bags are provided in the knee part of the knee pads. However, most of such knee pads have the air bags built-in or fixed on the knee pads. Due to the defects of the air bags themselves, they are extremely easy to deform and break after being impacted externally. Moreover, since the air bags of the knee pads are fixedly connected to the main body of the knee pads, they cannot be replaced, resulting in the entire knee pad being unable to be used continuously. Content of the Utility Model
[0005] Aiming at the defects existing in the prior art, the technical problem to be solved by the utility model is to provide an inflatable sports knee pad to improve the defects existing in the existing inflatable sports knee pads, solve the problem that the air bags of the existing inflatable sports knee pads cannot be replaced after deformation and breakage, so as to provide more effective protection for the knee joint during use.
[0006] To solve the above technical problem, the utility model proposes an inflatable sports knee pad, and adopts the following technical scheme:
[0007] An inflatable sports knee pad includes a knee pad sleeve and an air chamber member. A fixator is provided on the knee pad sleeve. The fixator is fixedly arranged at the middle position on the front of the knee pad sleeve. The fixator is annular. The annular fixator includes an upper ring and a lower ring. The lower ring is fixedly connected to the knee pad sleeve, and the upper ring is detachably buckled on the lower ring. The edge of the air chamber member is fixed between the upper ring and the lower ring of the fixator.
[0008] With this structure, the air chamber component can be replaced in time after deformation or damage, reducing the usage cost. The edge of the air chamber component is constrained in the fixator, which can fix the air chamber component and prevent the air chamber component from separating from the knee guard during use and affecting the protection effect. At the same time, using the air chamber component as the knee buffer pad, compared with traditional filling materials, it is lighter in weight, has better shock absorption effect and lower material price, and is more cost-effective while obtaining a good experience.
[0009] Furthermore, the upper ring is provided with insertion protrusions, and there are multiple insertion protrusions. The lower ring is provided with insertion holes, and there are multiple insertion holes. The insertion holes and the insertion protrusions correspond to each other one by one. The insertion design enables quick installation between the upper and lower rings, and has reliable strength, improving the structural stability between components.
[0010] Furthermore, a repeatedly detachable structure is provided between the air chamber component and the knee guard. The repeatedly detachable structure is a magic tape. The back of the air chamber component is adhered to the hook surface of the magic tape, and the outer side of the knee guard is adhered to the loop surface of the magic tape. The magic tape is a reusable bonding device with low cost and good bonding effect. Using the magic tape enables the air chamber component to be fixed on the knee guard and can be disassembled at any time.
[0011] Furthermore, the air chamber component is provided with an air inlet, an air inlet channel and an air chamber. The air inlet is arranged at one end of the air inlet channel, and one end of the air chamber is communicated with the air inlet channel. An independent one-way air inlet valve is provided between any air chamber and the air inlet channel. The one-way air inlet valve enables gas to enter the air chamber from the air inlet channel but cannot flow reversely. The air chamber bulges outwards in the inflated state. Since each independent air chamber is provided with a separate one-way air inlet valve, when a certain air chamber ruptures and loses pressure, the remaining air chambers can still play a protective role.
[0012] Furthermore, the air chamber component includes an outer diaphragm. The outer diaphragm is divided into upper and lower layers and is sealed around. The two layers of outer diaphragms are bonded to form an air chamber dividing line and an air passage dividing line. Independent air chambers are formed on both sides of the air chamber dividing line. The air passage dividing line is located at one end of the air chamber and extends along the parallel direction of the air chamber. An air inlet channel is formed on the side of the air passage dividing line facing away from the air chamber. For such an air chamber component, the processing difficulty of the air chamber and the air inlet channel is small, and the processing cost is low.
[0013] Furthermore, the air chamber component further includes a check valve membrane. The check valve membrane has two layers. The check valve membrane is overlapped along the air passage dividing line and arranged between the two layers of outer diaphragms. The air passage dividing line bonds the two layers of check valve membranes to the two layers of outer diaphragms respectively, and the two layers of check valve membranes are not bonded to form a one-way air inlet valve. The characteristic of the present utility model is that there are many one-way air inlet valves. How to ensure that a one-way air inlet valve is formed in each air chamber while having a low cost is the key to the commercial success of this solution. The one-way air inlet valve formed by such a check valve membrane has a clever structure, good sealing effect and low cost, and well solves the above problems.
[0014] Further, the air chamber is in the shape of a candied haws bunch, having bulging parts and connecting parts. When inflated, the bulging parts are formed by at least one layer of outer diaphragm bulging outward. The connecting parts connect two adjacent bulging parts, and the bulging parts and connecting parts of adjacent air chambers are arranged alternately. With such a structure, the size of the connecting parts is small, which can fully reduce the deformation resistance. At the same time, for the air chamber in the shape of a candied haws bunch, two adjacent air chambers can be better approximated and fitted, and the protection effect is good.
[0015] Further, the knee protector main body further includes elastic bands. There are multiple elastic bands. One end of each elastic band is fixedly connected to one side of the knee protector sleeve, and a repeated connection structure is formed between the other end of the elastic band and the knee protector sleeve. The repeated connection structure can adopt the way of magic tape, buckle, etc. The elastic bands cooperate with the repeated connection structure to change the size of the knee protector sleeve, making it more fitting to the user's leg.
[0016] Further, a plurality of silicone anti-slip strips are arranged on the inner side of the knee protector sleeve. The silicone anti-slip strips increase the friction between the knee protector sleeve and the leg, preventing the knee protector sleeve from shifting or slipping during exercise.
[0017] In summary, as a knee buffer pad, such an inflatable sports knee protector air chamber part can be replaced at will, reducing the use cost. At the same time, as a good shock absorption device, the air chamber part also greatly improves the protection effect of the knee protector. Description of the Drawings

Detailed implementation mode
[0025] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] As Figure 1 shown, an inflatable sports knee pad includes a knee pad sleeve 1 and an air chamber member 4. A fixator 3 is provided on the knee pad sleeve 1. The fixator 3 is fixedly arranged at the middle position on the front of the knee pad sleeve 1. The fixator 3 is annular. The annular fixator 3 includes an upper ring 31 and a lower ring 32. The lower ring 32 is fixedly connected to the knee pad sleeve 1, and the upper ring 31 is detachably buckled on the lower ring 32. The edge of the air chamber member 4 is fixed between the upper ring 31 and the lower ring 32 of the fixator 3.
[0027] With this structure, the air chamber member can be replaced in time after deformation or damage, reducing the use cost. The edge of the air chamber member is restrained in the fixator, and the fixator can fix the air chamber member to prevent the air chamber member from separating from the knee pad sleeve during use and affecting the protection effect. At the same time, using the air chamber member as a knee buffer pad, compared with traditional filling materials, it is lighter in weight, better in shock absorption effect, and lower in material price, which is more economically beneficial while obtaining a good experience.
[0028] Furthermore, the upper ring 31 is provided with a plurality of plugging protrusions, and the lower ring 32 is provided with a plurality of plugging holes. The plugging holes and the plugging protrusions correspond one by one. The plugging design enables quick installation between the upper and lower rings and has reliable strength, improving the structural stability between components.
[0029] As Figure 3 shown in the schematic diagram of the connection method between the air chamber member and the knee pad sleeve, a repeatedly detachable structure is provided between the air chamber member 4 and the knee pad sleeve 1. The repeatedly detachable structure is a magic tape 5. The back surface of the air chamber member 4 is adhered to the hook surface 51 of the magic tape, and the outer side of the knee pad sleeve 1 is adhered to the fuzzy surface 52 of the magic tape. The magic tape 5 is a repeatedly adhesive device with low cost and good sticking effect. Using the magic tape 5 enables the air chamber member 4 to be both fixed on the knee pad sleeve 1 and removable at any time.
[0030] As Figure 2Schematic diagram of the flat structure of the air cavity component shown. The air cavity component 4 is provided with an air inlet 41, an air inlet channel 42, and an air cavity chamber 43. The air inlet 41 is arranged at one end of the air inlet channel 42. One end of the air cavity chamber 43 is communicated with the air inlet channel 42. An independent one-way air inlet valve 46 is arranged between any air cavity chamber 43 and the air inlet channel 42. The one-way air inlet valve 46 enables gas to enter the air cavity chamber 43 from the air inlet channel 42 but cannot flow in the reverse direction. The air cavity chamber 43 bulges outwards in the inflated state. Since each independent air cavity chamber 43 is provided with a separate one-way air inlet valve 46, when a certain air cavity chamber 43 ruptures and loses pressure, the remaining air cavity chambers 43 can still play a protective role.
[0031] Furthermore, the air cavity component 4 includes an outer diaphragm 45. The outer diaphragm 45 has two layers and is sealed around. The two layers of the outer diaphragm 45 are bonded to form an air cavity separation line 431 and an air passage separation line 421. Independent air cavity chambers 43 are formed on both sides of the air cavity separation line 431. The air passage separation line 421 is located at one end of the air cavity chamber 43 and extends along the juxtaposed direction of the air cavity chamber 43. An air inlet channel 42 is formed on the side of the air passage separation line 421 facing away from the air cavity chamber 43. For such an air cavity component 4, the processing difficulty of the air cavity chamber 43 and the air inlet channel 42 is small, and the processing cost is low.
[0032] Furthermore, the air cavity component 4 further includes a check valve membrane 45. The check valve membrane 45 has two layers. The check valve membrane 45 is overlapped along the air passage separation line 421 and arranged between the two layers of the outer diaphragms 44. The air passage separation line 421 bonds the two layers of the check valve membrane 45 to the two layers of the outer diaphragms 44 respectively. The two layers of the check valve membrane 45 are not bonded to form a one-way air inlet valve 46. The characteristic of the present utility model is that there are more one-way air inlet valves 46. How to ensure that a one-way air inlet valve 46 is formed in each air cavity chamber while having a low cost is the key to whether this solution can achieve commercial success. The one-way air inlet valve 46 formed by such a check valve membrane 45 has a clever structure, good sealing effect, and low cost, and well solves the above problems.
[0033] Furthermore, the air cavity chamber 43 is in the shape of a candied haws string and has a bulging part 432 and a connecting part 433. When the bulging part 432 is inflated, it bulges outwards by at least one layer of the outer diaphragm 44. The connecting part 433 communicates adjacent two bulging parts 432. The bulging parts 432 and the connecting parts 433 of adjacent air cavity chambers are arranged in a staggered manner. With such a structure, the size of the connecting part 433 is small, which can fully reduce the deformation resistance. At the same time, for the air cavity chamber 43 in the shape of a candied haws string, adjacent two air cavity chambers 43 can be better approximated and fitted, and the protection effect is good.
[0034] Furthermore, the knee protector main body further includes a plurality of elastic bands 2. One end of each elastic band 2 is fixedly connected to one side of the knee protector sleeve 1, and a repeated connection structure is formed between the other end of the elastic band 2 and the knee protector sleeve 1. This repeated connection structure can adopt methods such as Velcro and buckles. The elastic bands cooperate with the repeated connection structure to change the size of the knee protector sleeve, making it more fitting to the user's leg.
[0035] Furthermore, a plurality of silicone anti-slip strips are provided on the inner side of the knee protector sleeve 1. The silicone anti-slip strips increase the friction between the knee protector sleeve and the leg, preventing the knee protector sleeve from shifting or slipping during exercise.
[0036] In summary, such an inflatable sports knee protector air chamber part serves as a knee buffer pad. The air chamber part can be replaced at will, reducing the use cost. At the same time, as a good shock absorption device, the air chamber part also greatly improves the protection effect of the knee protector.
[0037] In short, the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
