Specifically, the gas container 7 receives the compressed gas injected from the outside through the intake pipe 6. The valve 4 is used to control the flow of compressed gas in the gas container 7. Specifically, if the valve 4 is opened, the compressed gas in the gas container 7 is input to the connecting pipe 3, and enters the inflatable belt 2 through the connecting pipe 3. If the valve 4 is closed, the valve 4 blocks the input of compressed gas in the gas container 7 to the connecting pipe 3. The valve 4 The internal structure will be described in detail in FIGS. 2 to 5.

[0030] Referring to FIG. 2, the feeding door 4 includes, but is not limited to, a control valve body 401, a movable inclined slider 402, a first spring 403, a sliding groove 404, a second spring 405, and a first sealing ring 406. The needle valve 407, the first air guiding tube 40 8 , the second air guiding tube 409 , the first groove 410 and the second groove 411 .

[0031] the movable inclined slider 402, the first spring 403, the sliding slot 404, the second spring 405, the first sealing ring 406, the needle valve 407, the first air guiding tube 408, the second air guiding tube 409, the first concave The groove 410 and the second groove 411 are disposed in the control valve body 401.

[0032] The first groove 410 is horizontally disposed at an intermediate position of the control valve body 401, and the second groove 411 is vertically disposed at a position upper left of the control valve body 401.

[0033] Specifically, the first spring 403 and the needle valve 407 are both disposed in the first groove 410, wherein the first spring 403 is wound on the surface of the needle valve 407, the needle The valve 407 maintains the elastic force to the right in the horizontal direction by the action of the first spring 403.

[0034] The end of the needle valve 407 is connected to the draw tape 5, and the user can pull the needle valve 407 through the draw tape 5.

The first sealing ring 406 is disposed in the first groove 410, the needle valve 407 also passes through the first sealing ring 406, and the sealing ring 406 is configured to prevent the first groove 410 from leaking. gas.

[0035] In addition, the movable inclined slider 402 and the second spring 405 are disposed in the second groove 411, wherein the second spring 405 is wound around the surface of the movable inclined slider 402. The movable diagonal slider 402 is movable up and down in the vertical direction by the second spring 405. A plurality of chutes 404 are disposed on the surface of the needle valve 407, and the chutes 404 are engaged with the movable diagonal sliders 402. When the bottom of the movable slanting slider 402 is located in the chute 404, the movable slanting slider 402 catches the needle valve 407, so that the needle valve 407 stops moving. It should be noted that, referring to Fig. 2, when the needle valve 407 is horizontally moved to the left, the movable oblique slider 402 is convex upward. In other embodiments, the movable diagonal slider 402, the sliding slot 404, the second spring 405, and the second recess 411 function to prevent the needle valve after the user pulls the needle valve 407 through the strap 5 407 rebounds to the right under the action of the first spring. In other embodiments, the movable ramp slider 402, the chute 404, the second spring 405, and the second recess 411 may be omitted.

[0036] The left side of the control valve body 401 is provided with a first air guiding tube 408 and a second air guiding tube 409, wherein the first air guiding tube 408 is connected to the gas container 7, and the second air guiding tube 409 is The connecting pipe 3 is connected. The first air guiding tube 408 and the second air guiding tube 409 are both connected to the first groove 410. The first guide The air tube 408 and the second air tube 409 are also associated with the second groove 411.

[0037] The compressed gas in the gas container 7 is input to the valve 4 through the first air pipe 408, and is input to the connecting pipe 3 through the second air pipe 409, and then the compressed gas is input to the air by the connecting pipe 3. Belt 2

[0038] The needle valve 407 and the top of the first groove 410 are both pointed structures.

[0039] As shown in FIG. 2, when the tip of the needle valve 407 is in close contact with the tip of the first groove 410, the gas in the first air pipe 408 is used by the needle valve 407. Blocked without flowing into the second air duct 409.

[0040] As shown in FIG. 3, when the user pulls the needle valve 407吋 through the draw tape 5, the needle valve 407 moves to the left. When the tip of the needle valve 407 is disengaged from the tip of the first groove 410, the gas in the first air pipe 408 flows into the second air pipe 409 through the first groove 410, and the gas enters. The inflatable waistband 2 causes the inflatable waistband 2 to bulge, buffering the impact of the fall, and reducing the damage caused by the fall.

[0041] The working principle of the manual anti-drop protection device is as follows: The manual anti-drop protection device is worn on a user protection part (for example, a knee part, a waist part, a hand joint part, etc.), and the strap 5 is bound. In the user's hand, when the user's body suddenly becomes severely tilted (for example, falls), the arm tensioning belt 5 pulls the needle valve 407 to the left, and the needle valve 407 is separated from the tip of the first groove 410, the gas The gas in the container 7 enters the second air guiding tube 409 from the first air guiding tube 408. The gas in the second air guiding tube 409 is quickly inflated to the inflating belt 2 through the connecting tube 3, so that the inflatable belt 2 is rapidly inflated, so that the user can slam the impact of the user's fall and reduce the user's injury. After use, the user deflates the inflatable belt 2 through the deflation valve 1.

The above is only a preferred embodiment of the present invention, and thus does not limit the scope of the patent of the present invention, and the equivalent structure or equivalent process transformation using the specification and the drawings of the present invention, or directly or indirectly In other related technical fields, the same is included in the scope of patent protection of the present invention.
