DETAILED DESCRIPTION

[0021] In order to make the technical means, the creation features, the purpose and the effect of the utility model easy to understand

[0022] It is understood that the utility model is further described below in combination with specific embodiments.

[0023] For example Figure 1 , Figure 2 , Figure 3As shown, this utility model provides a respirator for rapid oxygen filling, including a shoulder strap frame 1 and a breathing mask 5. An assembly mechanism 2 is provided on the rear side of the shoulder strap frame 1, and an oxygen cylinder 3 is provided on the top of the assembly mechanism 2. An air tube 4 is fixedly connected to the output end of the oxygen cylinder 3, and the other end of the air tube 4 is fixedly connected to the front input end of the breathing mask 5. The assembly mechanism 2 includes an extended rear plate 21, which is fixedly installed on the rear side of the shoulder strap frame 1. An assembly placement plate 22 is fixedly installed on the rear side of the extended rear plate 21. An assembly groove 23 is formed on the top of the assembly placement plate 22, and the oxygen cylinder 3 is located inside the assembly groove 23. A drive box 24 is fixedly installed on the bottom of the assembly placement plate 22. The bottom of the inner wall of 23 is provided with a sliding groove 231, and the top of the drive box 24 is provided with a sliding groove 241. The sliding groove 231 and the sliding groove 241 are connected vertically. A positive and negative threaded rod 242 is movably installed on the left side of the inner wall of the sliding groove 241. The right end of the positive and negative threaded rod 242 passes through to the right side of the drive box 24 and is fixedly installed with a knob 243. The left and right sides of the outer wall of the positive and negative threaded rod 242 are respectively provided with threaded walls with opposite threads. The outer walls of the two threaded walls are threaded with movable plates 244. The top of the two movable plates 244 passes through the sliding groove 231 to the inner cavity of the assembly groove 23 and is fixedly installed with an arc-shaped clamping plate 245. The two arc-shaped clamping plates 245 are located on the left and right sides of the oxygen cylinder 3 respectively.

[0024] After carrying the oxygen cylinder 3 on the back using the shoulder strap frame 1, the oxygen cylinder 3 can be carried along with it using the assembly mechanism 2. At the same time, the oxygen in the oxygen cylinder 3 can be delivered to the breathing mask 5 using the ventilation tube 4. When it is necessary to assemble the oxygen cylinder 3, simply place the oxygen cylinder 3 in the assembly slot 23 opened at the top of the assembly placement plate 22, and then rotate the knob 243 on the right side of the drive box 24 to drive the positive and negative threaded rod 242 in the slide groove 241 to rotate. By using the threaded walls of the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rod 242 to connect with the threads of the two moving plates 244, the two moving plates 244 and the arc-shaped clamping plate 245 on their tops can be driven to move closer to each other, clamping and fixing the oxygen cylinder 3 placed in the assembly slot 23. This not only allows for quick assembly and installation, but also accommodates oxygen cylinders 3 of different sizes.

[0025] like Figure 4 As shown, the extended rear plate 21 has a vertically penetrating fixing groove. A sliding positioning box 211 is fixedly installed on the inner wall of the fixing groove. The top of the sliding positioning box 211 extends to the top of the extended rear plate 21. The sliding positioning box 211 has a vertically penetrating adjusting groove. A sliding plate 212 is slidably installed in the inner cavity of the adjusting groove. A first strap 213 is fixedly installed on the upper right side of the sliding plate 212. A Velcro hook surface 214 is fixedly glued to the front side of the first strap 213. A second strap 215 is fixedly installed on the upper left side of the sliding plate 212. A Velcro loop surface 216 is fixedly glued to the rear side of the second strap 215.

[0026] When the bottom of the oxygen cylinder 3 is fixed, the whole will be located at the rear side of the sliding plate 212, and then the binding band one 213 and the binding band two 215 on the left and right sides of the sliding plate 212 are used to wrap and adhere to the outer wall of the oxygen cylinder 3 through the cooperation of the hook surface 214 and the fuzzy surface 216, so as to ensure the stability of the upper half of the oxygen cylinder 3.

[0027] As shown in Figure 5 The left side of the sliding positioning box 211 is provided with a threaded hole 2111 penetrating into the adjusting sliding groove inner cavity, the inner circle of the threaded hole 2111 is provided with a threaded rod 2112, the left end of the threaded rod 2112 is fixedly provided with a locking knob 2113, the right end of the threaded rod 2112 is overlapped with the left side of the sliding plate 212, and the bottom end of the sliding plate 212 is fixedly provided with a limiting plate 2121, which can prevent the sliding plate 212 from being pulled out and falling upward;

[0028] When the fixed oxygen cylinder 3 is shorter, the sliding plate 212 only needs to be slid downward in the adjusting sliding groove of the sliding positioning box 211, and after reaching the specified height, the locking knob 2113 is selected to drive the threaded rod 2112 to threadedly rotate in the threaded hole 2111, gradually move to the right side, until the right end of the threaded hole 2111 abuts against the left side of the sliding plate 212, so that the sliding plate 212 is fixed, and the height adjustment is completed.

[0029] Now the working principle of the quick filling oxygen respirator will be described in detail.

[0030] As shown in Figures 1-5 When the oxygen cylinder 3 is fixed, the whole will be located at the rear side of the sliding plate 212, and then the binding band one 213 and the binding band two 215 on the left and right sides of the sliding plate 212 are used to wrap and adhere to the outer wall of the oxygen cylinder 3 through the cooperation of the hook surface 214 and the fuzzy surface 216, so as to ensure the stability of the upper half of the oxygen cylinder 3. When the fixed oxygen cylinder 3 is shorter, the sliding plate 212 only needs to be slid downward in the adjusting sliding groove of the sliding positioning box 211, and after reaching the specified height, the locking knob 2113 is selected to drive the threaded rod 2112 to threadedly rotate in the threaded hole 2111, gradually move to the right side, until the right end of the threaded hole 2111 abuts against the left side of the sliding plate 212, so that the sliding plate 212 is fixed, and the height adjustment is completed.

[0031] The utility model has been described in detail above, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the utility model are within the protection scope of the utility model.
