By squeezing the protective plate 16, the push rod 15 can open the sliders 13 on both sides. At the same time, the support arm 17 will also be squeezed and deformed to a certain extent. When the slider 13 slides to a certain position, the slider 13 will squeeze the first spring 14. At this time, under the elastic action of the first spring 14 and the internal torsion spring at the hinge of the support arm 17, a certain reaction force can be applied to buffer the force of the foreign object hitting the protective plate 16. In this process, the protective plate 16 is blocked in front of the tubular reactor body 1, which can play an anti-collision role of the tubular reactor body 1 when in use, improve the protective buffering effect of the tubular reactor body 1, and reduce the tubular reactor body 1 has no protective effect, resulting in the tubular reactor body 1 is easily damaged when it is hit by foreign objects.

[0027] Further, such as Figure 3 , Figure 4As shown, the side wall of the base 11 is fixedly connected to the column 2; the side wall of the column 2 is slidably connected to the annular block 21; the second spring 22 is fixedly connected between the annular block 21 and the base 11; the annular block 21 is fixedly connected to the protective plate 16; the side wall of the protective plate 16 is provided with a sliding hole 23; the sliding hole 23 and the column 2 are slidably matched; when in use, when the protective plate 16 is impacted and squeezed by foreign objects, the annular block 21 can slide on the side wall of the column 2 and squeeze the second spring 22, and the column 2 will pass through the sliding hole 23, at this time The elasticity of the second spring 22 can exert a certain reaction force on the annular block 21, thereby buffering the force of foreign objects hitting the protective plate 16.

When the fixed block 35 is pressed into the mounting block 3, the slot 36 can be made to correspond to the position of the plug block 33. At this time, under the elasticity of the third spring 32, a certain thrust can be applied to the plug block 33 to push the plug block 33 into the side wall of the slot 36 so that it is stuck and the base 11 is fixed. When the base 11 needs to be disassembled, the pull rod 34 is held and pulled to pull the plug block 33 out of the side wall of the slot 36, so that the fixed block 35 can be taken out from the mounting block 3. In this process, by inserting the fixed block 35 into the mounting block 3 for fixing, the convenience of disassembly and maintenance of the base 11 can be achieved, the flexibility of the base 11 when in use can be improved, and the difficulty of disassembly and maintenance caused by damage to the protective plate 16 can be reduced, which increases a certain amount of workload.

[0029] Further, such as Figure 1-Figure 3As shown, the side wall of the protective plate 16 is provided with a groove 4; the side wall of the groove 4 is fixedly connected to a plurality of spring rods 41; the spring rods 41 are evenly distributed on the side wall of the groove 4 and have the same structure; the end of the spring rod 41 is fixedly connected to a cleaning brush plate 42; when in use, when the column 2 passes through the sliding hole 23, the elasticity of the spring rod 41 can push the cleaning brush plate 42 to fully fit the side wall of the column 2, at this time, the side wall of the column 2 can be cleaned by the cleaning brush plate 42, and the dust and impurities attached to the side wall of the column 2 can be swept away.

[0030] Further, such as Figure 2 , Figure 4 , Figure 5 As shown, a pair of elastic sheets 5 are fixedly connected to the side walls of the mounting block 3; the elastic sheets 5 are symmetrically arranged on both sides of the mounting block 3 and have the same structure; the side walls of the elastic sheets 5 are fixedly connected to the sponge blocks 51; when in use, by pressing the fixing block 35 into the mounting block 3, the fixing block 35 will squeeze the elastic sheets 5 on both sides, and at this time, the fixing block 35 will be pushed to the middle of the mounting block 3 under the elasticity of the elastic sheets 5, and the fixing block 35 will also slide toward the middle of the elastic sheets 5 on both sides, and the sponge blocks 51 will also fit with the side walls of the fixing block 35 to wipe off the dust and impurities attached to the side walls of the fixing block 35 to improve the smoothness of the sliding between the fixing block 35 and the mounting block 3. In this process, by pressing the fixing block 35 into the mounting block 3, it can play a limiting role when pressing the fixing block 35 into the mounting block 3, thereby improving the convenience of installing the base 11 and reducing the difficulty in aligning the two, which makes the installation process more cumbersome.

[0031] Further, such as Figure 5 As shown, a support block 6 is fixedly connected to the end of the pull rod 34; a slot 61 is provided on the side wall of the support block 6; when in use, the support block 6 is hooked and pulled by inserting a finger into the side wall of the slot 61, so that the insertion block 33 can be pulled.

In this process, the elastic plate 7 can further play a protective and cushioning role when the protective plate 16 is hit, thereby improving the safety protection function of the tubular reactor body 1, reducing the cushioning effect of the support arm 17, and affecting the protective effect of the tubular reactor body 1.

[0033] Working principle: When in use, when the tubular reactor body 1 is hit by a foreign object, the foreign object will first hit the wall of the protective plate 16. By squeezing the protective plate 16, the top rod 15 can open the sliders 13 on both sides, and the support arm 17 will also be squeezed to produce a certain deformation. When the slider 13 slides to a certain position, the slider 13 will squeeze the first spring 14. At this time, under the elastic action of the first spring 14 and the internal torsion spring at the hinge of the support arm 17, a certain reaction force can be applied to buffer the force of the foreign object hitting the protective plate 16. When in use, when the protective plate 16 is hit and squeezed by a foreign object, the annular block 21 can slide on the side wall of the column 2 and squeeze the second spring 14. The spring 22 is squeezed, and the column 2 passes through the sliding hole 23. At this time, the elasticity of the second spring 22 can apply a certain reaction force to the annular block 21, so as to buffer the force of the foreign object hitting the protective plate 16. At the same time, when the column 2 passes through the sliding hole 23, the foreign object can be pushed away. When in use, by holding the base 11, the fixing block 35 is pressed into the fixing groove on the side wall of the mounting block 3. At this time, the fixing block 35 will squeeze the plug block 33 and squeeze it open. When the fixing block 35 is pressed into the mounting block 3, the slot 36 can correspond to the position of the plug block 33. At this time, under the elasticity of the third spring 32, a certain thrust can be applied to the plug block 33, pushing the plug block 33 onto the side wall of the slot 36, so that It is stuck to fix the base 11. When the base 11 needs to be disassembled, the pull rod 34 is held and pulled to pull the insert block 33 out of the side wall of the slot 36, so that the fixing block 35 can be taken out from the mounting block 3. When in use, when the column 2 passes through the sliding hole 23, the elasticity of the spring rod 41 can push the cleaning brush plate 42 to fully fit the side wall of the column 2. At this time, the side wall of the column 2 can be cleaned by the cleaning brush plate 42 to sweep away the dust and impurities attached to the side wall of the column 2. When in use, by pressing the fixing block 35 into the mounting block 3, the fixing block 35 will squeeze the elastic sheets 5 on both sides. At this time, the elastic sheets 5 will push the fixing block 35 under the elasticity and push it to the mounting block. The fixing block 35 slides toward the middle of the elastic sheets 5 on both sides, and the sponge block 51 also fits against the side walls of the fixing block 35 to wipe off the dust and impurities attached to the side walls of the fixing block 35, so as to improve the smoothness of sliding between the fixing block 35 and the mounting block 3. When in use, the support block 6 is hooked and pulled by inserting a finger into the side wall of the card slot 61, so as to pull the insertion block 33. When in use, when the support arm 17 is squeezed to deform it, the elastic plate 7 is also squeezed to deform it to a certain extent. Then, a certain reaction force can be applied under the elastic action of the elastic plate 7 to support the support arm 17 and buffer the protective plate 16.
