[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0022] like Figures 1-4As shown, a stainless steel corrugated hose for connecting gas appliances includes a pipe body 101 and a connecting pipe 102. The connecting pipe 102 is inserted into the interior of the pipe body 101. A connecting ring 103 is sleeved on the surface of the connecting pipe 102. A connecting mechanism is provided at the connection between the connecting pipe 102 and the pipe body 101. A sealing mechanism is provided on the surface of the connecting pipe 102. The connecting mechanism includes a telescopic spring 201, a sleeve 202, a through hole 203, a sealing ball 204, a groove 205 and an installation groove 206. The telescopic spring 201 is movably sleeved on the connecting end of the surface of the pipe body 101. One end of the compression spring 201 is fixedly connected to the surface of the tube body 101, the sleeve 202 is slidably connected to the connecting end on the surface of the tube body 101 and is fixedly connected to the other end of the expansion spring 201, the sleeve 202 is movably sleeved on the surface of the expansion spring 201, and the through holes 203 are opened on the surface of the tube body 101. There are several through holes 203, and they are evenly opened on the surface of the tube body 101. The sealing balls 204 are respectively arranged inside the through holes 203, and the grooves 205 are opened at the ends of the sleeve 202. The depth of the grooves 205 is adapted to the sealing balls 204. The mounting groove 206 is provided on the surface of the connecting tube 102, and the sealing ball 204 is connected with the mounting groove 206. When connecting the connecting tube 102 and the tube body 101, the sleeve 202 on the surface of the tube body 101 can be pulled first to squeeze the telescopic spring 201, and then the connection of the connecting tube 102 is inserted into the inside of the tube body 101. While plugging, the connecting tube 102 will squeeze the sealing ball 204 inside the through hole 203, and make the sealing ball 204 move outward inside the through hole 203 and be located inside the groove 205. Then, the connecting tube 102 is plugged in. 02, and then remove your hand from the kit 202, and you can push the kit 202 to move in the opposite direction under the elastic force of the telescopic spring 201, and the kit 202 will squeeze the sealing ball 204, so that the sealing ball 204 is stuck in the inside of the installation groove 206. Finally, under the elastic force of the telescopic spring 201, you can push the kit 202 and limit it. At the same time, the kit 202 will squeeze the sealing ball 204 and be stuck in the inside of the installation groove 206, and the connecting pipe 102 can be connected to the pipe body 101, thereby effectively improving the convenience of hose connection and enabling it to be connected quickly.

[0023] like Figure 3As shown, the sealing mechanism includes a track groove 301, a magnet 302, a sealing ring 303 and an iron block 304. The track groove 301 is opened on the surface of the connecting ring 103, the magnet 302 is fixedly connected to the inner wall of the track groove 301, the sealing ring 303 is sleeved on the surface of the connecting ring 103 and the kit 202, the iron block 304 is fixedly connected to the inner wall of the sealing ring 303, the iron block 304 is slidably connected to the inside of the track groove 301 and cooperates with the magnet 302 for adsorption. When the connection between the connecting pipe 102 and the tube body 101 is completed, the staff can hold the sealing ring 303 and then move the sealing ring 303 close to the kit 202. By pulling one side of the sealing ring 303, the iron block 304 will be inside the track groove 301. Then, when the sealing ring 303 completes the sleeve on the surface of the kit 202, the ring is rotated about thirty degrees, which will drive the iron block 304 to rotate inside the track groove 301. After rotation, the iron block 304 and the magnet 302 can be adsorbed, and the iron block 304 can be limited to the inside of the track groove 301. At the same time, the sealing ring 303 can be set and limited on the surface of the kit 202 and the connecting ring 103, thereby strengthening the sealing effect of the connection and avoiding gas leakage, which brings safety hazards to users.

[0024] like Figure 2 As shown, the top and bottom of the end of the connecting tube 102 are fixedly connected with a protrusion 401, and the top and bottom of the inner wall of the connecting end of the tube body 101 are provided with a groove 402 that cooperates with the protrusion 401. When the connecting tube 102 is plugged into the tube body 101, the protrusion 401 can be matched with the groove 402 to avoid the connection of the connecting tube 102 to the inner wall of the tube body 101 when the connecting tube 102 is plugged in, which causes the sealing ball 204 to be unable to accurately fit with the mounting groove 206, thereby playing an auxiliary limiting role for the connecting tube 102.

[0025] like Figure 2 As shown, a sealing groove is provided on the surface of the connecting tube 102, and a sealing member 5 is fixedly connected to the inner wall of the sealing groove. After the connecting tube 102 is connected to the tube body 101, the sealing connection effect between the connecting tube 102 and the tube body 101 can be increased under the action of the sealing member 5, thereby avoiding gas leakage and improving its safety.

[0026] like Figure 2 As shown, there are several mounting grooves 206, which are evenly distributed on the surface of the connecting pipe 102. Under the action of multiple mounting grooves 206, the action of multiple sealing balls 204 can be adapted to the multiple mounting grooves 206, which not only increases the sealing effect between the tube body 101 and the connecting pipe 102, but also increases the connection stability between the tube body 101 and the connecting pipe 102 due to the even distribution of multiple sealing balls 204, making it safer.

[0027] like Figure 4As shown, the through hole 203 is conical, and the diameter of the inner side of the through hole 203 is smaller than the diameter of the outer side of the through hole 203. The through hole 203 is conical, which can prevent the sealing ball 204 from passing through the through hole 203 and detaching from the inside of the through hole 203, thereby protecting the sealing ball 204.

[0028] like Figure 1 and Figure 3 As shown, the surface of the sealing ring 303 is fixedly connected with a protrusion 6. There are several protrusions 6, which are evenly distributed on the surface of the sealing ring 303. When using the sealing mechanism, the friction coefficient between the palm of the staff and the sealing ring 303 can be increased, and the sealing ring 303 will not slip on the surface when the sealing ring 303 is pulled or rotated.

[0029] The working principle of the present invention is as follows: when connecting the connecting tube 102 and the tube body 101, you can first pull the sleeve 202 on the surface of the tube body 101 and squeeze the telescopic spring 201, then plug the connecting part of the connecting tube 102 into the inside of the tube body 101, and while plugging, the connecting tube 102 will squeeze the sealing ball 204 inside the through hole 203, and make the sealing ball 204 move outward inside the through hole 203 and be located inside the groove 205, and then when the connecting tube 102 is plugged in, remove your hand from the sleeve 202, and you can push the sleeve 202 to move in the opposite direction under the elastic force of the telescopic spring 201, and make the sleeve 202 squeeze the sealing ball 204, so that the sealing ball 204 is stuck in the installation groove 206, and finally, under the elastic force of the telescopic spring 201, you can push the sleeve 202 and limit it, and at the same time, the sleeve 202 will squeeze the sealing ball 204. 04 is clipped into the inside of the mounting groove 206, and the connecting pipe 102 can be connected to the pipe body 101. When the connecting pipe 102 is connected to the pipe body 101, the staff can hold the sealing ring 303 and then pull the sealing ring 303 toward the side close to the kit 202. While pulling the sealing ring 303, the iron block 304 will be inside the track groove 301. Then, when the sealing ring 303 completes the sleeve on the surface of the kit 202, the ring is rotated about thirty degrees, and the iron block 304 will be driven to rotate inside the track groove 301. After rotation, the iron block 304 and the magnet 302 can be adsorbed, and the iron block 304 can be limited to the inside of the track groove 301. At the same time, the sealing ring 303 can be set and limited on the surface of the kit 202 and the connecting ring 103, thereby strengthening the sealing effect of the connection and avoiding gas leakage, which brings safety hazards to users.

[0030] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
