Description
Technical Field
[0001] This utility model relates to the field of backpacks, and in particular to an easily adjustable air respirator backpack. Background Technology
[0002] A backpack is a bag with one or two shoulder straps that can be hung on a person's back. Backpacks are widely used in various situations because they free up the hands and make it easy to carry heavy objects, including backpacks for breathing apparatus.
[0003] During a fire, the canister is secured to the user's shoulders via straps on the back panel of the breathing apparatus backpack. The canister contains compressed air to provide air for the user during firefighting and rescue operations. When the user moves, the canister on the straps at the rear of the back panel may shake, and the canister's connection point is susceptible to external impacts, potentially causing damage and leakage. This can affect the effectiveness of the breathing apparatus backpack. Utility Model Content
[0004] The technical problem this invention aims to solve is that when the user moves, the canister on the rear strap of the backpack shakes, and the interface of the canister is easily damaged by external impacts, resulting in leakage and affecting the effectiveness of the air breathing machine backpack.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an easily adjustable air respirator backpack, including a back panel and a mounting assembly. A shoulder strap is provided on one side of the back panel, a binding strap is provided on one side of the back panel, and a canister is provided on one side of the binding strap. A protective device is provided on the back panel by means of the mounting assembly. The protective device includes a slide rail. A first protective plate is slidably connected to one side of the slide rail. A first bolt is threaded into one side of the first protective plate. One side of the first bolt abuts against the slide rail. A second protective plate is slidably connected to one side of the first protective plate. A second bolt is threaded into the side of the first protective plate near the second protective plate. The second bolt abuts against the second protective plate.
[0006] The aforementioned components achieve the following effects: In the event of a fire, the straps on the back panel of the breathing apparatus backpack secure the canister, and the straps are fixed to the user's shoulders. The canister contains compressed air to provide air to the user, facilitating fire rescue. When using the canister, the first protective plate can be moved within the slide rail to reach the canister's interface. Then, the second protective plate can be moved to seal a gap on one side of the first protective plate. The first bolt can then be rotated to pass through the first protective plate and engage with the slide rail. The second bolt can then be rotated to engage with the second protective plate, thus securing the first and second protective plates. By using these protective devices, the canister's interface is protected, preventing it from shaking on the back straps during user movement and avoiding external impacts that could damage or leak the canister's interface. This improves the effectiveness of the breathing apparatus backpack.
[0007] Preferably, an operating block is fixedly connected to one side of the second bolt, and the operating block is adapted to the size of the second bolt.
[0008] The effect achieved by the above-mentioned components is to increase the contact area between the second bolt and the operator by using the second bolt, making it easier for the operator to rotate the second bolt.
[0009] Preferably, the second protective plate has a groove on the side near the back plate, and the size of the groove is adapted to the size of the tank interface.
[0010] The effect achieved by the above-mentioned components is that the grooves on the second protective plate allow pipes connected to the outside of the tank to pass through the grooves and pass through the second protective plate, so that the second protective plate does not affect the use of the tank interface.
[0011] Preferably, a connecting rope is fixedly connected to one side of the first bolt, and the side of the connecting rope away from the first bolt is fixedly connected to the first protective plate.
[0012] The effect achieved by the above components is to connect the first bolt to the first protective plate by using a connecting rope, thereby preventing the first bolt from being lost.
[0013] Preferably, the first protective plate has two arc strips fixedly connected to the side near the slide rail, and the arc surfaces of the two arc strips are smooth.
[0014] The effect achieved by the above components is to reduce the friction between the slide rail and the first protective plate by using the arc strip, making it easier for the operator to move the first protective plate.
[0015] Preferably, the mounting assembly includes a mounting block, one side of which is fixedly connected to a back plate, a third bolt is threaded into one side of the mounting block, a connecting plate is threaded to one side of the third bolt, and one side of the connecting plate is fixedly connected to a slide rail.
[0016] The effect achieved by the above components is as follows: when using the protective device, the slide rail can be moved so that the connecting plate on one side of the slide rail can be inserted into the mounting block. Then, the third bolt can be rotated so that the third bolt passes through the mounting block and is fixed to the connecting plate. Then the position of the connecting plate and the slide rail can be fixed. By using the mounting components, the protective device can be quickly fixed to the back plate, which makes it convenient for operators to use the protective device.
[0017] Preferably, guide plates are fixedly connected to both sides of the mounting block, and the guide plates are inclinedly arranged on both sides of the mounting block.
[0018] The effect achieved by the above components is to increase the entry size of the mounting block by using a guide plate, making it easier to insert the connecting plate into the mounting block.
[0019] Preferably, a nut is threaded into one side of the third bolt, and one side of the nut abuts against the mounting block.
[0020] The effect achieved by the above components is to fix the position of the third bolt by using a nut, so that the third bolt can be more firmly fixed to the connecting plate.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] By using protective devices, the interface of the canister can be shielded and protected, preventing the canister on the back strap from shaking when the user moves, and avoiding external impacts that could damage and leak the interface of the canister, thereby improving the effectiveness of the air breathing machine backpack.
