[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a decomposition furnace with a pipe anti-loosening structure, including a decomposition furnace body 1, an installation pipe 2 installed on one side of the decomposition furnace body 1, a connecting pipe 3 installed at one end of the installation pipe 2, and a fixing mechanism 4 provided at one end of the installation pipe 2.
[0022] The fixing mechanism 4 includes a slide groove 41, a fixing groove 42, a fixing pipe 43, a fixing block 44, and a control component 45. The slide groove 41 is provided on the inner side of the mounting pipe 2, and the fixing groove 42 is provided on the inner wall of the slide groove 41. The fixing pipe 43 is installed inside the connecting pipe 3, and the fixing block 44 is fixed on the outer side of the fixing pipe 43. The control component 45 is provided on the outer side of the connecting pipe 3. Through the arrangement of the slide groove 41, fixing groove 42, fixing pipe 43, fixing block 44, and control component 45, when it is necessary to install the connecting pipe 3, first align the fixing block 44 on the outer side of the fixing pipe 43 with the slide groove 41 and insert it. At this time, the mounting pipe 2 and the connecting pipe 3 are simultaneously connected. Then, by rotating the fixing pipe 43, the fixing block 44 on its outer side slides into the fixing groove 42 inside the slide groove 41. At this time, the mounting pipe 2 and the connecting pipe 3 can be connected by a flange. In daily use, the fixing block 44 and the fixing groove 42 stably fix the connecting pipe 3 to one side of the mounting pipe 2.
[0023] Furthermore, the control component 45 includes a toggle block 451, a limiting groove 452, a fixing ring 453, a spring 454, a limiting ring 455, and a sealing ring 456. The toggle block 451 is provided on the outer side of the fixing tube 43, the limiting groove 452 is formed on the outer wall of the connecting tube 3, the fixing ring 453 is fixed on the inner wall of the connecting tube 3, the spring 454 is installed on the outer side of the fixing ring 453, the limiting ring 455 is fixed on the outer wall of the fixing tube 43, and the sealing ring 456 is sleeved on the outer side of the limiting ring 455. Through the toggle block 451, the limiting groove 452, and the sealing ring 456, the control component 451... The fixing ring 453, spring 454, limiting ring 455 and sealing ring 456 are configured so that when the fixing block 44 slides into the slide groove 41, the lever 451 is moved, and the lever 451 drives the fixing tube 43 to rotate, thereby causing the fixing block 44 on the outside of the fixing tube 43 to slide into the fixing groove 42. At the same time, the limiting ring 455 will squeeze the spring 454 against the mounting tube 2. When the fixing block 44 slides into the fixing groove 42, the spring 454 will provide an outward force, making the connection between the mounting tube 2 and the connecting tube 3 more secure.
[0024] Furthermore, the inner wall size of the slide 41 matches the outer wall size of the fixing block 44. The slide 41 is symmetrically opened with respect to the central axis of the mounting tube 2. With the setting of the fixing block 44, when in use, as the fixing block 44 slides into the fixing groove 42, the connecting tube 3 will not be able to separate from the mounting tube 2.
[0025] Furthermore, multiple sets of fixing grooves 42 are provided, and the outer wall size of the fixing tube 43 matches the inner wall size of the mounting tube 2. By setting the fixing grooves 42, the fixing block 44 is restricted in position after installation during use.
[0026] Furthermore, the fixing block 44 is installed symmetrically with the outer wall size of the fixing tube 43. With the setting of the fixing tube 43, during use, the fixing tube 43 extending from the inside of the connecting tube 3 is connected to the installation tube 2 in advance, and at the same time, the connection between the installation tube 2 and the connecting tube 3 is reinforced.
[0027] Furthermore, the lever 451 is symmetrically installed around the central axis of the fixed tube 43, and the inner wall size of the limiting ring 455 matches the outer wall size of the fixed tube 43. Through the setting of the lever 451, when in use, the lever 451 and the limiting groove 452 work together to limit the sliding space of the fixed tube 43 while controlling it.
[0028] Furthermore, the spring 454 is symmetrically installed around the central axis of the limiting ring 455, and multiple sets of sealing rings 456 are provided. With the setting of the spring 454, when the fixing tube 43 extends out of the connecting tube 3 during use, the limiting ring 455 at the tail of the fixing tube 43 will squeeze the spring 454. When the fixing block 44 is inserted into the fixing groove 42, the spring 454 provides an outward thrust, making the connection between the mounting tube 2 and the connecting tube 3 more secure.
[0029] Working principle: When installing the connecting pipe 3, first align the fixing block 44 on the outside of the fixing pipe 43 with the slide groove 41 and insert it. At this time, the installation pipe 2 and the connecting pipe 3 are simultaneously connected. Then, by rotating the fixing pipe 43, the fixing block 44 on its outside slides into the fixing groove 42 inside the slide groove 41. At this time, the installation pipe 2 and the connecting pipe 3 can be connected by the flange. In daily use, the fixing block 44 and the fixing groove 42 stably fix the connecting pipe 3 to one side of the installation pipe 2. When the fixing block 44 slides into the slide groove 41, the lever 451 is moved. The lever 451 drives the fixing pipe 43 to rotate, thereby causing the fixing block 44 on the outside of the fixing pipe 43 to slide into the slide groove 41. In the fixing groove 42, the limiting ring 455 will press the spring 454 against the mounting tube 2. When the fixing block 44 slides into the fixing groove 42, the spring 454 will provide an outward force, making the connection between the mounting tube 2 and the connecting tube 3 more secure. When the fixing block 44 slides into the sliding groove 41, the toggle block 451 is moved. The toggle block 451 drives the fixing tube 43 to rotate, thereby causing the fixing block 44 on the outside of the fixing tube 43 to slide into the fixing groove 42. At the same time, the limiting ring 455 will press the spring 454 against the mounting tube 2. When the fixing block 44 slides into the fixing groove 42, the spring 454 will provide an outward force, making the connection between the mounting tube 2 and the connecting tube 3 more secure.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
