Description

Technical Field

[0001] The utility model relates to the technical field of flue connection, in particular to an assembled flue connection structure. Background Art

[0002] At present, finished concrete flues are mostly used for kitchen flues in residential buildings. Especially in the kitchens of residential buildings, flues are installed. Generally speaking, flues are in the shape of rectangular columns. Since flues are multi-section, good sealing must be ensured when adjacent flues are connected.

[0003] However, the connection structure of the existing assembled flue only adopts a common wrapping and sealing structure, and there is only one layer of sealing structure, which cannot ensure the sealing performance of the connection between adjacent flues, resulting in the phenomenon of flue gas leakage. For this reason, an assembled flue connection structure is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that in the prior art, the display module is easily damaged. Once damaged, it takes a lot of time for the staff to disassemble the display module, affecting its maintenance progress, and to propose an assembled flue connection structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An assembled flue connection structure includes two flue pipes arranged in butt joint. One end of the flue pipe is fixedly provided with a sealing insertion ring, and the other end of the flue pipe is provided with a sealing slot matching with the sealing insertion ring; both ends of the flue pipe are fixedly provided with clamping rings. The side wall of the clamping ring is provided with an inclined contact surface. Two arc-shaped clamping sleeves are symmetrically sleeved outside adjacent two clamping rings. The inner walls of the two arc-shaped clamping sleeves are in extrusion contact with the contact surfaces of the clamping rings. A fixing mechanism is arranged at one end where the two arc-shaped clamping sleeves face each other.

[0007] Preferably, the fixing mechanism includes a fixing ring, a bolt and a nut. The fixing ring is fixedly arranged on the outer wall of the end of the arc-shaped clamping sleeve. Adjacent two fixing rings are fixedly connected through the cooperation of the bolt and the nut.

[0008] Preferably, an auxiliary sealing strip is fixedly arranged on the side wall of the sealing insertion ring, and an auxiliary sealing groove matching with the auxiliary sealing strip is arranged on the inner side wall of the sealing slot.

[0009] Preferably, the contact surfaces on adjacent two clamping rings are arranged in a back-to-back distribution, and the inner walls of the top and bottom of the arc-shaped clamping sleeve are respectively in contact with the contact surfaces on the two clamping rings.

[0010] Preferably, a rubber sealing pad is arranged at the contact part between the arc-shaped clamping sleeve and the clamping ring.

[0011] Preferably, the sealed insertion ring and the flue duct are integrally formed, and the clamping ring and the flue duct are fixedly welded.

[0012] Compared with the prior art, the present utility model provides an assembled flue connection structure, which has the following beneficial effects:

[0013] 1. For this assembled flue connection structure, through the sealed insertion ring and the sealed slot provided on the flue duct, when two adjacent flue ducts are butted, the sealed insertion ring is inserted into the inside of the sealed slot, so that the adjacent pipe bodies can be hermetically inserted and matched, playing a role of primary sealing.

[0014] 2. For this assembled flue connection structure, through the clamping ring and the arc-shaped clamping sleeve provided between two adjacent flue ducts, after the two adjacent flue ducts are hermetically inserted, then the two arc-shaped clamping sleeves are sleeved outside the clamping ring, so that the inner wall of the arc-shaped clamping sleeve contacts the contact surface of the clamping ring. This can not only relatively pull the two clamping rings to make the two flue ducts firmly connected, but also cover and seal the outside of the butt joint of the two flue ducts, playing a role of secondary sealing.

[0015] The parts not involved in this device are the same as or can be implemented by the prior art. The present utility model adopts a double-sealing structure and a structure that drives the relative tension to fix the flue, so that the flue can be hermetically connected and is not prone to smoke leakage, improving the assembly effect.
