Greatly improve the shortcomings of the use of technology, this is the design purpose of this creation.

Therefore, the purpose of the present invention is to provide a sports equipment auxiliary device, mainly for a pneumatic fastening protection device.

In order to achieve the above object, the present invention aims to provide an inflation fastening protection device, comprising: an inflation chamber and an inflation device disposed in the inflation chamber, the inflation device comprising an inflatable bladder, the inflatable bladder An intake adjustment switch is disposed in the intake end, the intake adjustment switch is elastically sealed with an intake hole disposed on the intake end, and the intake hole is exposed outside the inflation chamber, and the inflatable bladder is An air outlet adjusting switch is disposed in the air outlet end, and the air outlet adjusting switch is elastically sealed with an air outlet hole disposed on the air outlet end, and the air outlet hole is located in the air in the air chamber. The pneumatic fastening protection device is characterized in that the upper end surface of the air intake adjusting switch is elastically sealed with the air inlet hole through a spring provided at the bottom of the air intake adjusting switch. The pneumatic fastening protection device is characterized in that the upper end surface of the air outlet adjusting switch passes through an air outlet The spring provided at the bottom of the switch is elastically sealed with the air outlet. The pneumatic fastening protection device is characterized in that a venting chamber is disposed in an air inlet end or an air outlet end of the air sac, wherein the venting chamber is elastically matched with a deflation switch, and the top of the venting switch is exposed in the venting chamber In vitro, the bottom of the venting chamber communicates with the inflation chamber. The above-mentioned inflatable fastening protection device has the advantages of simple structure and reasonable design, and the utility model replaces the inner liner in the helmet, and uses the inflatable bladder to inflate and exhaust the inflation chamber, so that the user can adjust the inflation chamber to make the head and the head The proper fit of the liner expands the versatility of the helmet and improves the safety of the helmet. In addition to the use of the inner liner of the helmet, the utility model can be applied to other protective gears or shoes to play the functions of fastening, shock absorption, buffering and protection, and can also be used as a filler, such as a stealth heightening pad.

Of course, the present invention is allowed to differ in some of the parts, or the arrangement of the parts, but the selected embodiments are described in detail in the present specification, and the construction thereof is shown in the drawings.

FIG. 1 is a schematic view of the present inflated fastening protection device.

FIG. 2 is a schematic view of the present inflated fastening protection device.

The technical means by which this creation is used to achieve the above objectives are described in detail below with the following implementation diagrams, which are further understood and agreed upon. Please refer to FIG. 1 for a schematic diagram of the present inflated fastening protection device, and FIG. 2 is a schematic view of the present inflated fastening protection device.

Please refer to FIG. 1 and FIG. 2 , which is intended to provide an inflation fastening protection device including an inflation chamber 2 and an inflation device 1 disposed in the inflation chamber 2 , wherein the inflation device 1 charges the inflation chamber 2 Deflation.

The inflator primarily includes an inflatable bladder 101. An intake adjustment switch 103 is disposed in the intake end 102 of the inflatable bladder 101. The upper end surface of the intake adjustment switch 103 is elastically sealed by a spring disposed at the bottom of the intake adjustment switch 103 and an intake aperture 104 disposed at the intake end 102. Cooperating, wherein the air inlet 104 is exposed outside the inflation chamber 2 for intake.

Therefore, under normal circumstances, the intake adjustment switch 103 is always against the intake hole 104 seals the air inlet 104. The intake adjusting switch 103 preferably has a circular upper end surface and a cylindrical body connected to the upper end surface. The circular upper end surface cooperates with the air inlet hole 104, and the cylindrical body cooperates with the spring. An air outlet adjusting switch 107 is disposed in the air outlet end 105 of the airbag 101. The upper end surface of the air outlet adjusting switch 107 is elastically sealed and fitted with the air outlet 108 disposed on the air outlet end 105 through a spring disposed at the bottom of the air outlet adjusting switch 107, wherein the air outlet 108 is provided. Located within the inflation chamber 2 for inflating the inflation chamber 2. Therefore, under normal conditions, the air outlet adjusting switch 107 always seals the air outlet 108 against the air outlet 108. The air outlet adjusting switch 107 preferably has a circular upper end surface and a cylindrical body connected to the upper end surface. The circular upper end surface cooperates with the air outlet hole 108, and the cylindrical body cooperates with the spring.

In order to be able to discharge the gas in the inflation chamber 2, a venting chamber 109 is provided in the inlet end 102 or the outlet end 105 of the inflatable bladder 101. The venting chamber 109 is elastically fitted with a deflation switch 106, and the top of the venting switch 106 is exposed in the plenum chamber. 2, the bottom of the venting chamber 109 communicates with the inflation chamber 2. Normally, the vent switch 106 seals the deflation chamber 109. In use, while the inflatable bladder 101 is being squeezed, the springs on the inlet end 102 and the outlet end 105 are elastically deformed such that external air enters the inflatable bladder 101 from the air inlet 104 and then enters the inflatable chamber 2 from the air outlet 108. The inflation chamber 2 is inflated. When it is necessary to vent the plenum chamber 2, the vent switch 106 is pressed, so that the deflation chamber 109 communicates with the plenum chamber 2, and the gas in the plenum chamber 2 is exhausted.

The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the present invention, so any change in the value or substitution of equivalent elements should still fall within the scope of the present invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and has filed a patent application.
