Abstract

The utility model provides a sports kneepad which comprises a kneepad body, wherein a tightening part is fixedly connected to the kneepad body and comprises a bag sleeve, the bag sleeve is fixedly connected to an upper end port of the kneepad body, a ring-shaped air bag is arranged in the bag sleeve, an inflating device is connected to the ring-shaped air bag and used for inflating and deflating the air bag, and the size of an opening of the bag sleeve is changed by the aid of the air bag which expands when heated. When the knee pad moves, the leg generates a large amount of heat, so that air in the air bag is thermally expanded, the opening of the bag sleeve becomes smaller, the more violent the movement is, the higher the temperature rise of the air bag is, the stronger the binding capacity of the knee pad is, and the more difficult the knee pad is to fall off.

Description

Sports kneepad

Technical Field

The utility model relates to the field of protectors, in particular to an inflatable knee protector.

Background

Along with the popularization of the consciousness of national fitness, modern people pay more and more attention to physical exercise, people exercise the bodies by taking part in volleyball, obstacle surmounting competition, mountain bike racing, skiing, skating, motorcycle racing and other sports, but in the process of sports, the people inevitably collide with the bodies, the bodies are easy to scratch, and even fracture can occur. Flexible knee braces are used by athletes and others engaged in vigorous physical activity to protect the knee from damage and to avoid deterioration from existing injuries. During normal walking, in occupations involving physical labor, especially during strenuous exercise, the knee may experience abnormal movements caused by rapid changes in direction, fatigue, uneven surfaces, or impact. So that the kneepad can easily fall off from the knee to influence the movement.

The existing knee pad tightening force strengthening method generally adopts the modes of binding ropes, thread gluing tapes and the like, which can play a certain role in strengthening the fixing capacity, but the knee pad can possibly fall off in the process of strenuous exercise or the contact friction of the knee pad, and cannot play a role of the knee pad.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a sports knee pad which is not easy to fall off.

The utility model is realized by adopting the following technical scheme: a sports knee pad comprises a knee pad body, wherein a tightening part is fixedly connected to the knee pad body and comprises a bag sleeve, the bag sleeve is fixedly connected to an upper end port of the knee pad body, a ring-shaped air bag is arranged in the bag sleeve, an inflating device is connected to the ring-shaped air bag and used for inflating and deflating the air bag, and the size of an opening of the bag sleeve is changed by the air bag through thermal expansion.

Preferably, the material of the bag cover is the same as that of the body.

Preferably, the material of the air bag is natural rubber.

Preferably, the inflation device comprises an inflation nozzle, and the inflation nozzle is communicated with the interior of the air bag through an inflation tube.

Compared with the prior art, the knee pad comprises a knee pad body, wherein a tightening part is fixedly connected to the knee pad body, the tightening part comprises a bag sleeve, the bag sleeve is fixedly connected to the upper end port of the knee pad body, a ring-shaped air bag is arranged in the bag sleeve, an inflating device is connected to the ring-shaped air bag and used for inflating and deflating the air bag, and the size of an opening of the bag sleeve is changed by the air bag through thermal expansion. When the knee pad moves, the leg generates a large amount of heat, so that air in the air bag is thermally expanded, the opening of the bag sleeve becomes smaller, the more violent the movement is, the higher the temperature rise of the air bag is, the stronger the binding capacity of the knee pad is, and the more difficult the knee pad is to fall off.

FIG. 2 is a schematic cross-sectional view taken at A-A of FIG. 1;

in the figure: 1. a body; 2. a tightening part; 21. a bag sleeve; 22. an air bag; 3. an inflator; 31. an air charging nozzle; 32. and an inflation tube.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1-2: a sports kneepad comprises a kneepad body 1, wherein a tightening part 2 is fixedly connected to the kneepad body 1, and the tightening part 2 is used for tightening the sports kneepad to prevent the kneepad from falling off during strenuous sports. The tight binding part 2 comprises a bag sleeve 21, the bag sleeve 21 is fixedly connected to a port at the upper end (one side above the knee when the knee pad is worn) of the body 1, a ring-shaped air bag 22 is arranged in the bag sleeve 21, an inflating device 3 is connected to the ring-shaped air bag 22, the inflating device 3 is used for inflating and deflating the air bag 22, and the size of the opening of the bag sleeve 21 is changed by the expansion of the air bag 22 due to heating. When the knee pad is used, the knee pad is firstly sleeved on a leg, then a proper amount of air is filled into the air bag 22 through the inflating device 3, the air bag 22 supports the bag sleeve 21 due to inflation deformation, so that the bag sleeve 21 is tightly attached to the leg, and when the knee pad moves, the air in the air bag 22 is subjected to thermal expansion due to the large amount of heat generated by the leg, so that the opening of the bag sleeve 21 becomes smaller, and the more violent the movement is, the higher the temperature of the air bag 22 is, the stronger the binding capacity of the knee pad is, and the more difficult the knee pad falls off.

The material of the bag cover 21 is the same as that of the body 1, so that the leg is not uncomfortable when the leg-protecting bag is worn due to the difference of the material of the bag cover 21. The air bag 22 is made of natural rubber, and in the same material, the natural rubber material has better elasticity and is more favorable for thermal expansion deformation.

The inflator 3 includes an inflation nozzle 31, and a small inflation nozzle 31 is selected as the inflation nozzle 31 so as not to affect the movement of the inflation nozzle 31, and the inflation nozzle 31 (for example, a basketball inflation nozzle 31) is communicated with the inside of the airbag 22 through an inflation tube 32. An inflator is used to inflate the interior of the bladder 22 through the inflation nozzle 31. After the kneepad is used, the gas is released, and the kneepad is taken down.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
