[0001] The utility model relates to the technical field of sleeve chimneys, in particular to a fixing structure for sleeve chimneys. Background Art

[0002] The inner wall of a sleeve-type chimney generally plays a key role in anti-corrosion and flue gas exhaust within the outer steel cylinder. It is mostly made of relatively expensive non-ferrous metal sheets. The inner cylinder is composed of a series of pipe sections connected to form a chimney inner cylinder section.

[0003] The traditional method of connecting the inner chimney and the outer chimney is to weld flanges on the outer wall of the bottom end of the inner chimney and the upper surface of the outer chimney, and complete the connection between the inner chimney and the outer chimney by bolting the two flanges together. This connection not only takes time to weld, but is also time-consuming and labor-intensive to operate, resulting in low construction efficiency. In order to solve this technical problem, the utility model proposes a fixing structure for a sleeve chimney. Utility Model Content

[0004] The main purpose of the utility model is to provide a fixing structure for a sleeve chimney, which can effectively solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A fixing structure for a sleeve chimney comprises an outer chimney, a sliding groove is provided inside the outer chimney, an inner side wall of the sliding groove is slidably connected to an insert block, a limiting mechanism is designed inside the outer chimney, a cross bar is connected inside the outer chimney, the outer surface of the cross bar is rotatably connected to a support plate, the outer surface of the support plate is connected to a limiting block, the outer surface of the support plate is connected to an anti-sliding block, the inner surface of the outer chimney is connected to a base, the upper surface of the base contacts the inner chimney, and the inner surface of the outer chimney is slidably connected to a stop block.

[0007] Preferably, the limiting mechanism comprises a blocking block, the outer surface of the blocking block is slidably connected to the interior of the outer chimney, and the outer surface of the blocking block is slidably connected to the interior of the inserting block.

[0008] Preferably, a spring is connected to the outer surface of the blocking block, and one end of the spring away from the blocking block is connected to the inside of the insert block.

[0009] Preferably, the outer surface of the blocking block is connected with a transverse plate, the outer surface of the transverse plate is slidably connected to the inside of the insert block, and the outer surface of the transverse plate is in contact with the inner side wall of the sliding groove.

[0010] Preferably, the outer surface of the transverse plate is connected with a blocking cover, and the outer surface of the blocking cover is slidably connected to the outer surface of the insert block.

[0011] Preferably, the outer surface of the insert is slidably connected to the inside of the inner chimney, the outer surface of the support plate is slidably connected to the inside of the outer chimney, and the outer surface of the inner chimney is slidably connected to the inside of the outer chimney.

[0012] Preferably, the outer surface of the stopper is slidably connected to the outer surface of the support plate, the upper surface of the stopper is connected to a transmission block, and a slot is provided inside the stopper.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the utility model, through the cooperation between the plug block and the support plate and other components, first, the plug block can be moved. When the inner chimney is placed in the outer chimney, the base will limit the position to which the inner chimney can move, so that the plug block can be inserted into the inner chimney, thereby limiting the position of the inner chimney. The support plate can be moved. When the inner chimney is inserted into the outer chimney, it is necessary to move the support plate to a position where it can be inserted into the inner chimney, so as to support the inner chimney and make it difficult for the inner chimney to tilt. In this way, the position of the inner chimney can be limited by only moving the plug block and the support plate. The operation is simple, and the problem of low efficiency of fixing by flange plates is solved.

[0015] In the utility model, the blocking block can limit the position of the plug-in block through the cooperation between the blocking block and the card slot and other components. After the plug-in block is moved to the appropriate position, a part of the blocking block can be inserted into the outer chimney to limit the position of the plug-in block, so that the position of the plug-in block is difficult to change. The card slot can engage with the anti-sliding block. In this way, when moving the outer chimney, the user can move the block to the top of the support plate, so that when the user lifts the support plate, the limit block on the support plate will engage with the card slot, so that the support plate cannot slide, so that the block blocking the support plate cannot be removed, and the user can move the outer chimney by moving the support plate, which is very convenient.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a fixing structure for a sleeve chimney includes an outer chimney 1, a slide groove 2 is opened inside the outer chimney 1, and an insert block 3 is slidably connected to the inner wall of the slide groove 2. The inner wall of the slide groove 2 is relatively smooth, and other objects are subject to less friction when moving on the inner wall of the slide groove 2. The slide groove 2 will limit the direction in which the insert block 3 can move, so that the position of the insert block 3 will not deviate.

[0024] The interior of the outer chimney 1 is designed with a limiting mechanism 4. The interior of the outer chimney 1 is connected to a cross bar 5, and the outer surface of the cross bar 5 is rotatably connected to a support plate 6. The outer chimney 1 will fix the position of the cross bar 5 so that the cross bar 5 cannot move, and provide support for the support plate 6 through the cross bar 5, so that the support plate 6 can rotate around the cross bar 5.

[0025] The outer surface of the support plate 6 is connected to a limiting block 7, and the outer surface of the support plate 6 is connected to an anti-sliding block 8. The support plate 6 will fix the position of the limiting block 7, and the limiting block 7 can be blocked on the surface of the limiting block 7. When the support plate 6 is perpendicular to the outer chimney 1, the user can put a rope loop on the support plate 6 and move the outer chimney 1 upward by pulling the rope loop. The limiting block 7 can prevent the rope loop from detaching from the support plate 6. The support plate 6 will limit the anti-sliding block 8, and the anti-sliding block 8 is an elongated version of the teeth.

[0026] The interior of the outer chimney 1 is connected to a base 9, the upper surface of the base 9 contacts the inner chimney 10, and the interior of the outer chimney 1 is slidably connected to a stopper 11. The outer chimney 1 will fix the position of the base 9 so that the base 9 cannot move. The base 9 provides support for the inner chimney 10, thereby limiting the position in which the inner chimney 10 can move within the outer chimney 1. The outer chimney 1 will limit the position in which the stopper 11 can move.

[0027] The limiting mechanism 4 includes a blocking block 401, the outer surface of the blocking block 401 is slidably connected to the inside of the outer chimney 1, and the outer surface of the blocking block 401 is slidably connected to the inside of the insert block 3. The blocking block 401 can be inserted into the inside of the outer chimney 1, and the insert block 3 will limit the direction of the blocking block 401 so that the position of the blocking block 401 will not deviate, and the blocking block 401 cannot be completely moved out of the insert block 3. In this way, after the blocking block 401 is inserted into the outer chimney 1, the insert block 3 can no longer move along the slide groove 2.

[0028] The outer surface of the blocking block 401 is connected to a spring 402, and the end of the spring 402 away from the blocking block 401 is connected to the inside of the insert block 3. The spring 402 can provide thrust for the blocking block 401, allowing the blocking block 401 to be partially moved out of the insert block 3 when there is no obstacle. The insert block 3 will limit the position of the spring 402.

[0029] The outer surface of the blocking block 401 is connected to the transverse plate 403, and the outer surface of the transverse plate 403 is slidably connected to the inside of the insert block 3. The outer surface of the transverse plate 403 contacts the inner wall of the slide groove 2. The blocking block 401 will fix the position of the transverse plate 403, and when the transverse plate 403 moves, it will move with the blocking block 401, and the insert block 3 will limit the position to which the transverse plate 403 can move.

[0030] The outer surface of the horizontal plate 403 is connected to a blocking cover 404, and the outer surface of the blocking cover 404 is slidably connected to the outer surface of the plug-in block 3. The horizontal plate 403 will limit the position of the blocking cover 404. When the horizontal plate 403 moves, it will move with the blocking cover 404, and the blocking cover 404 will block the hole opened in the plug-in block 3 to prevent external impurities from entering the plug-in block 3 through the hole.

[0031] The outer surface of the plug block 3 is slidably connected to the inside of the inner chimney 10, the outer surface of the support plate 6 is slidably connected to the inside of the outer chimney 1, and the outer surface of the inner chimney 10 is slidably connected to the inside of the outer chimney 1. By inserting the plug block 3 into the inner chimney 10, the position of the inner chimney 10 is restricted, so that the inner chimney 10 cannot move up and down. The support plate 6 can be inserted into the outer chimney 1, thereby providing support for the inner chimney, so that the inner chimney 10 will not move downward or tilt. A sealing gasket is provided at the contact position between the outer chimney 1 and the inner chimney 10. The outer chimney 1 is designed with the same grooves and holes as the inner chimney 10. If the length of the chimney needs to be extended, it is only necessary to put a larger outer chimney 1 on the surface of the outer chimney 1.

[0032] The outer surface of the stopper 11 is slidably connected to the outer surface of the support plate 6, and the upper surface of the stopper 11 is connected to the transmission block 12. A slot 13 is provided inside the stopper 11. The stopper 11 will limit the position of the support plate 6. When the support plate 6 is perpendicular to the outer chimney 1, the stopper 11 can be moved to a position to block the support plate 6, so that the support plate 6 cannot continue to move upward. The stopper 11 will fix the position of the transmission block 12, and when the transmission block 12 moves, it will move with the stopper 11. When the stopper 11 moves above the support plate 6, the slot 13 can engage with the anti-sliding block 8, so that the stopper 11 cannot continue to move horizontally.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
