Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Example 1, please refer to Figures 1 to 4 This utility model provides a technical solution: a fire-fighting smoke exhaust duct installation structure, including a duct body 1, with connectors 101 on both sides of the duct body 1, connecting posts 102 movably embedded on both sides of the inner walls of the two connectors 101, and sliding grooves 103 formed on both sides of the inner walls of the two connectors 101, with sliders 104 fixedly installed on both sides of the four connecting posts 102, the eight sliders 104 being divided into four groups of two, the outer surfaces of the four groups of sliders 104 being slidably connected to the inner surfaces of the sliding grooves 103, the inner sides of the two connectors 101 being threaded with first bolts 105, and support plates 106 fixedly installed on the outer sides of the four connecting posts 102, with the opposite sides of the four support plates 106 being fixedly... Four limiting plates 107 are fixedly installed. The inner sides of the four limiting plates 107 are movably connected to the outer surface of the pipe body 1. The inner sides of the four limiting plates 107 are threaded with second bolts 108. Two of the limiting plates 107 are provided with positive screws 110 at the top. The outer surfaces of the two positive screws 110 are threaded with sleeves 111. The inner top sides of the two sleeves 111 are threaded with reverse screws 112. The tops of the two reverse screws 112 are located at the bottom of the other two limiting plates 107. The top sides of the two limiting plates 107 are fixedly installed with sliding rods 109. The four sliding rods 109 are divided into two groups of two. The two groups of sliding rods 109 are slidably connected to the inside of the other two limiting plates 107.

[0031] In this embodiment, the operator can first place the pipe body 1 inside the hanger, and then push the support plate 106 inward to drive the connecting column 102 to slide inside the connector 101. Simultaneously, the connecting column 102 drives the slider 104 to slide on the inner surface of the groove 103. After the support plate 106 is pushed to a certain extent, the limiting plate 107 will adhere to the outer surface of the pipe body 1. Then, the operator can rotate the first bolt 105 so that one end adheres to the connecting column 102 to fix the width of the hanger. At the same time, the operator can rotate the sleeve 111, causing the forward screw 110 and the reverse screw 112 to rotate and move relative to each other inside the sleeve 111. When the forward screw 110 and the reverse screw 112 move, the limiting plate 107 and the support plate 106 pull the connecting column 102 and the connector. 101 performs synchronous relative movement, and simultaneously drives the top limiting plate 107 to slide on the outer surface of the slide rod 109, thereby allowing the support plate 106 and the connector 101 to fit against the top and bottom of the pipe body 1 for adjustment of the hanger. The second bolt 108 is rotated so that one end fits against the outer surface of the pipe body 1 to fix the pipe body 1. Through the structure of the connector 101 and the sleeve 111, the width and height of the hanger can be precisely adjusted to adapt to pipes of different sizes. The size of the hanger can be easily changed to ensure that the pipe body 1 is firmly fixed in the hanger, meeting the installation requirements of different smoke exhaust ducts. At the same time, personnel only need to push the support plate 106 and rotate the sleeve 111 to adjust the size of the hanger. The operation is simple, reducing the cumbersome steps during installation and improving work efficiency.

[0032] Example 2, as Figures 1 to 4 As shown, a connecting block 2 is fixedly installed on the top of each of the two sets of sliding rods 109. A first support column 201 is fixedly installed on the top of each of the two connecting blocks 2. A second support column 202 is movably embedded inside each of the two first support columns 201. Multiple pin holes 203 are opened inside each of the two second support columns 202. Pins 204 are movably connected inside each of the two first support columns 201. Both pins 204 match the multiple pin holes 203. Expansion bolts 205 are threadedly connected to both sides of the inside of each of the two second support columns 202.

[0033] In this embodiment, the operator can first embed the expansion bolt 205 into the wall to fix the hanger, then pull out the pin 204 to disengage it from the pin hole 203, and then pull down the connecting block 2 to allow the second support column 202 to slide inside the first support column 201, thereby adjusting the installation height of the hanger. The height of the hanger can be adjusted by the structure of the pin 204 and the second support column 202. This adjustment mechanism is simple and flexible, and can accurately adjust the position of the hanger according to actual needs, further increasing the applicability of the hanger.

[0034] Working principle: In use, the operator first places the pipe body 1 inside the hanger, then pushes the support plate 106 inward to cause the connecting column 102 to slide inside the connector 101. Simultaneously, the connecting column 102 drives the slider 104 to slide on the inner surface of the groove 103. After the support plate 106 is pushed to a certain extent, the limiting plate 107 will adhere to the outer surface of the pipe body 1. Then, the operator can rotate the first bolt 105 to make one end adhere to the connecting column 102, thus fixing the width of the hanger. Simultaneously, the operator can rotate the sleeve 111, causing the forward screw 110 and the reverse screw 112 to rotate and move relative to each other inside the sleeve 111. As the forward screw 110 and the reverse screw 112 move, the limiting plate 107 and the support plate 106 pull the connecting column 102 and the connecting plate 104 together. The connector 101 moves synchronously relative to the pipe body 1, and simultaneously drives the top limiting plate 107 to slide on the outer surface of the slide rod 109. This allows the support plate 106 and the connector 101 to fit against the top and bottom of the pipe body 1 for adjustment of the hanger. The second bolt 108 is then rotated so that one end fits against the outer surface of the pipe body 1 to fix the pipe body 1. Through the structure of the connector 101 and the sleeve 111, the width and height of the hanger can be precisely adjusted to accommodate pipes of different sizes. The size of the hanger can be easily changed to ensure that the pipe body 1 is firmly fixed in the hanger, meeting the installation requirements of different exhaust ducts. At the same time, personnel only need to push the support plate 106 and rotate the sleeve 111 to adjust the size of the hanger. The operation is simple, reducing the cumbersome steps during installation and improving work efficiency. In use, the operator can first insert the expansion bolts 205 into the wall to fix the hanger, then pull out the pin 204 to disengage it from the pin hole 203, and then pull down the connecting block 2 to allow the second support column 202 to slide inside the first support column 201, thereby adjusting the installation height of the hanger. The height of the hanger can be adjusted by the structure of the pin 204 and the second support column 202. This adjustment mechanism is simple and flexible, and can accurately adjust the position of the hanger according to actual needs, further increasing the applicability of the hanger.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
