[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0027] Embodiment one: please refer to Figures 1 to 6 :

[0028] The utility model provides a kind of windproof and shockproof device of steel chimney, comprising: steel chimney main body 1;

[0029] One of steel chimney main body 1 outside is provided with a reinforcing base 2 by integral molding, and the outer side of this steel chimney main body 1 is also slidably installed with a positioning sleeve 3, steel chimney main body 1 is used to guide flue gas outward, reinforcing base 2 is used to install reinforcing connecting plate 5, and positioning sleeve 3 is used to lock the position of reinforcing connecting plate 5;Four reinforcing supports 4 are installed in annular arrangement mode on the outer side of reinforcing base 2, and each of reinforcing support 4 is welded with a reinforcing connecting plate 5 at top end, and reinforcing support 4 is used to reinforce steel chimney;Four locking buckles 6 are welded in annular arrangement mode on the outer side of reinforcing base 2, and locking buckle 6 and locking block 7 can fix the height of positioning sleeve 3;Four locking blocks 7 are welded in annular arrangement mode on the outer side of positioning sleeve 3, and locking block 7 and locking buckle 6 can fix the height of positioning sleeve 3.

[0030] In the embodiment of the present disclosure, as shown in Figure 2 and Figure 6 Locking block 7 is trapezoidal block, and the top surface of locking block 7 is horizontal surface, and an inclined surface is arranged at the lower position of the outer side of locking block 7, when assembling, positioning sleeve 3 can be pushed to slide down to the bottom and hit down with rubber hammer, in this process, the top surface of locking buckle 6 will first contact with the inclined surface at the lower position of the outer side of locking block 7, then locking buckle 6 will appear elastic bending, finally locking block 7 will be embedded into the rectangular opening in the inner side of the top of locking buckle 6, so that the height of positioning sleeve 3 can be fixed.

[0031] In the embodiments of the present disclosure, as shown in Figures 1-5 The top of the reinforcing base 2 is arranged with four notched grooves in a ring shape, and the width of the notched grooves is equal to the width of the reinforcing connecting plate 5. When the reinforcing support 4 is installed, the reinforcing connecting plate 5 at the top end of the reinforcing support 4 can be placed in the notched groove outside the reinforcing base 2 and pushed down, and then the reinforcing connecting plate 5 can be clamped in the notched groove outside the reinforcing base 2. The width of the notched groove is equal to the width of the reinforcing connecting plate 5, which can avoid the reinforcing connecting plate 5 from shaking.

[0032] In the embodiments of the present disclosure, as shown in Figures 1-6 The locking buckle 6 is made of spring steel. When the positioning sleeve 3 moves downward to the bottom, the locking block 7 outside the positioning sleeve 3 can be clamped in the rectangular opening inside the top of the locking buckle 6. When assembled, the positioning sleeve 3 can be pushed down to slide to the bottom and hit downward with a rubber hammer. In this process, the top of the locking buckle 6 will first contact the inclined surface below the outside of the locking block 7, and then the locking buckle 6 will be elastically bent. Finally, the locking block 7 will be embedded in the rectangular opening inside the top of the locking buckle 6, so the height of the positioning sleeve 3 can be fixed.

[0033] In the embodiments of the present disclosure, as shown in Figure 3 and Figure 4 The bottom inner wall of the positioning sleeve 3 is also provided with four notched grooves. When the positioning sleeve 3 moves downward to the bottom, the upper part of the reinforcing connecting plate 5 can be embedded in the notched groove on the bottom inner wall of the positioning sleeve 3. Therefore, the positioning sleeve 3 can wrap the upper part of the reinforcing connecting plate 5 inside, so as to lock the upper position of the reinforcing connecting plate 5, which can avoid the upper and lower movement of the reinforcing connecting plate 5 and the disengagement of the reinforcing connecting plate 5 from the reinforcing base 2.

[0034] In the embodiments of the present disclosure, as shown in Figure 2 and Figure 5 The bottom of the notched groove outside the reinforcing base 2 is provided with a cylindrical protrusion, and the bottom of the reinforcing connecting plate 5 is also provided with a corresponding cylindrical groove. When the reinforcing support 4 is installed, the reinforcing connecting plate 5 at the top end of the reinforcing support 4 can be placed in the notched groove outside the reinforcing base 2 and pushed down. At this time, the cylindrical protrusion at the bottom of the notched groove outside the reinforcing base 2 can be embedded in the cylindrical groove at the bottom of the reinforcing connecting plate 5, so as to limit the horizontal movement of the bottom position of the reinforcing connecting plate 5.

[0035] In the embodiments of the present disclosure, as shown in Figures 1-6 The outer wall of the steel chimney body 1 is provided with four strip protrusions, and the inner wall of the positioning sleeve 3 is also provided with four corresponding vertical strip guide grooves. When the positioning sleeve 3 slides up and down, the vertical strip guide grooves on the inner wall of the positioning sleeve 3 can slide with the strip protrusions on the outer wall of the steel chimney body 1, so as to avoid the rotation of the positioning sleeve 3 outside the steel chimney body 1.

[0036] The working principle of the embodiment is as follows: when the steel chimney is installed, the steel chimney body 1 can be assembled vertically through bolts and nuts first, and then the reinforcing support 4 can be assembled. When the reinforcing support 4 is installed, only the positioning sleeve 3 needs to be pushed upward to the top first, and then the reinforcing connecting plate 5 at the top end of the reinforcing support 4 is placed in the notch groove outside the reinforcing base 2 and is pushed downward. At this time, the cylindrical protrusion at the bottom of the notch groove outside the reinforcing base 2 will be embedded in the cylindrical groove at the bottom of the reinforcing connecting plate 5, so that the bottom position of the reinforcing connecting plate 5 can be limited to move horizontally. Then the positioning sleeve 3 can be pushed down to the bottom and hit downward with a rubber hammer. During this process, the top surface of the locking buckle 6 will first contact the inclined surface at the lower position outside the locking block 7, and then the locking buckle 6 will be elastically bent. Finally, the locking block 7 will be embedded in the rectangular opening inside the top of the locking buckle 6, so that the height of the positioning sleeve 3 can be fixed. At this time, the positioning sleeve 3 can wrap the upper part of the reinforcing connecting plate 5 inside, so as to lock the upper position of the reinforcing connecting plate 5, which can avoid the up and down movement of the reinforcing connecting plate 5 and the disengagement of the reinforcing connecting plate 5 from the reinforcing base 2. At this time, the circular plate at the bottom end of the reinforcing support 4 will also be close to the ground, so as to play a role in reinforcing the steel chimney and improving the windproof and shock resistance effect.
