Description

Technical Field

[0001] This application relates to the field of long-tube respirator technology, and in particular to a forced-air long-tube respirator. Background Technology

[0002] A supplied-air respirator (SEER) is a type of protective equipment used to ensure respiratory safety in hazardous environments. It typically consists of a mask, tubing, and an air supply system. Its working principle is to deliver fresh air from a safe area into the wearer's mask through the air duct, ensuring the wearer receives clean air and avoids inhaling toxic or harmful gases. These respirators are commonly used in high-risk industries such as chemical plants, mines, and firefighting, especially in areas with high levels of air pollution or harmful gases. Unlike standard self-contained breathing apparatus (SCBAs), SEERs rely on an external air source, making them more suitable for providing stable respiratory support during extended periods of operation.

[0003] However, in most air-purifying long-tube respirators, the connection between the respirator and the long hose is a direct-insertion connection, where the plug end of the long hose is directly inserted into the respirator's interface. This direct-insertion connection is not stable enough and is prone to detachment. Furthermore, there are gaps at the connection point, and repeated shaking can cause air leakage, thus affecting air delivery. Therefore, an air-purifying long-tube respirator was designed to solve the above-mentioned problems. Utility Model Content

[0004] To address this problem, this application provides a forced-air long-tube respirator.

[0007] Preferably, the mounting ring is square and is slidably connected to the side wall of the mounting frame.

[0008] Preferably, the clamping plate is semi-circular, and the clamping plate can be assembled into a clamping ring.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings Figs. 1-3 The application will be further described in detail.

[0020] The application embodiment discloses a long pipe respirator of air supply type. Figs. 1-3The utility model provides a kind of air supply type long tube respirator, including respirator main body 1, one side fixed connection interface 2 of respirator main body 1, long hose 14 is inserted on interface 2, respirator main body 1 is fixedly connected installation frame 3 on the upper and lower end of one side close to interface 2, reciprocating screw rod 4 is rotatably connected in installation frame 3, installation ring 5 is screw-connected on reciprocating screw rod 4, fixedly connected fixedly connected mounting plate 6 one side of installation ring 5, mounting plate 6 is slidably connected moving plate 7 one side close to interface 2, fixedly connected clamping plate 8 one side of moving plate 7, fixedly connected mounting bracket 9 one side of moving plate 7, fixedly connected sealing baffle 10 one side of mounting bracket 9;

[0021] Reciprocating screw rod 4 is used to drive installation ring 5 to move, so that installation ring 5 drives mounting plate 6 to move, and mounting plate 6 drives moving plate 7 to move, so that moving plate 7 moves close to interface 2 after moving, and moving plate 7 drives clamping plate 8 to move and clamps the side wall of long hose 14 inserted in interface 2, plays the role of auxiliary support long hose 14, improves the stability of connection.

[0022] By adopting the above technical scheme, clamping plate 8 is semicircular, and clamping plate 8 can be assembled into a clamping ring, as shown in Fig. 3 The inner side of clamping plate 8 is arc-shaped, and clamping plate 8 is matched with long hose 14, so as to be attached to the outer side wall of long hose 14, thereby stably clamping long hose 14.

[0023] By adopting the above technical scheme, sealing baffle 10 is arc-shaped, and sealing baffle 10 is tightly attached to the end wall of interface 2, as shown in Fig. 1 The gap at the connection can be shielded.

[0024] By adopting the above technical scheme, reciprocating screw rod 4 is fixedly connected with gear 41 at one end, gear 41 is engaged with gear plate 11 at one side, gear plate 11 is slidably connected with the side wall of respirator main body 1, pull plate 12 is fixedly connected with spring 13 at one side, and spring 13 is fixedly connected with the end wall of interface 2.

[0025] The implementation principle of a long-tube respirator with air supply in this embodiment is as follows: First, push the pull plate 12 on one side, causing the pull plate 12 to drive the gear plate 11 to move and compress the spring 13. When the gear plate 11 moves, it drives the gear 41 to rotate, causing the gear 41 to drive the reciprocating screw 4 to rotate. The reciprocating screw 4 drives the mounting ring 5 to move, causing the mounting ring 5 to drive the mounting plate 6 to move. The mounting plate 6 drives the moving plate 7 to move, so that the moving plate 7 moves away from the interface 2. Then, insert the plug of the long hose 14 into the interface 2. Then push the moving plate 7, causing the moving plate 7 to drive the clamping plate 8 to move. The clamping plate 8 drives the mounting bracket 9 on one side to move, and the mounting bracket 9 drives the sealing stop. Block 10 moves, causing the sealing block 10 to move close to the interface 2 and the plug connection. Then, the pull plate 12 is released, causing the spring 13 to drive the pull plate 12 to return to its original position, and driving the gear plate 11 to move. The gear plate 11 drives the gear 41 to rotate, causing the reciprocating screw 4 to drive the mounting ring 5 to move and return to its original position, and causing the mounting plate 6 to drive the moving plate 7 to move and return to its original position. This causes the clamping plate 8 to move and fit against the long hose 14, and the sealing block 10 to move and fit against the connection between the plug of the long hose 14 and the interface 2, forming a gap filling, reducing the amplitude of plug shaking, thereby reducing air leakage, and also assisting in supporting the long hose 14 to prevent the plug of the long hose 14 from directly separating from the interface 2.
