Description

Technical Field

[0001] The utility model provides an adjustable ventilation pipe connection structure, belonging to the technical field of ventilation pipes. Background Art

[0002] Ventilation ducts are pipes used in ventilation systems to transport air or gas. Ventilation ducts are usually used inside buildings or industrial facilities to transport fresh air to areas that need ventilation or to exhaust stale air through duct systems.

[0003] The length of the ventilation duct often has an important impact on the ventilation effect. The longer the ventilation duct, the greater the resistance, which leads to the need for a more powerful fan to drive the airflow in the ventilation system, thereby increasing energy efficiency and operating costs; and the ventilation duct often has problems such as unstable ventilation effect. Therefore, the ventilation duct often needs to be kept within an appropriate length. At the same time, for connected ventilation ducts, dust will accumulate over time, so they can be disassembled and cleaned by disassembling the ventilation duct connection structure. The existing connection and disassembly structure and length adjustment structure of the ventilation duct are often set separately, which increases the complexity of the ventilation duct structure, and therefore needs to be improved. Utility Model Content

[0006] As an improvement, a groove is provided in the installation tube, and the installation rod is located in the groove; a limit plate fixedly sleeved on the installation rod is provided in the groove, and a spring sleeved on the installation rod is provided in the groove.

[0007] As an improvement, the spring has a reserved compression amount when installed.

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] according to Figure 1-6As shown: the utility model provides an adjustable ventilation pipe connection structure: comprising a mounting tube 1 and a connecting tube 2; a slide groove 5 is provided in the mounting tube 1, and the connecting tube 2 is slidably arranged in the slide groove 5; the outer wall of the connecting tube 2 is provided with evenly distributed mounting holes 7, a mounting rod 6 is provided in the mounting tube 1, and the mounting rod 6 is inserted into one of the mounting holes 7; a connecting groove 14 is provided above the connecting tube 2, and a fixing block 3 is fixedly arranged above the connecting tube 2; an adjusting block 4 is slidably arranged in the fixing block 3, and the adjusting block 4 is located in the connecting groove 14; a screw 12 capable of controlling the adjusting block 4 to slide up and down is rotatably arranged in the fixing block 3.

[0021] The connecting tube 2 is connected to the mounting tube 1 by plugging, and the setting of the mounting rod 6 and the mounting hole 7 can facilitate the disassembly of the connecting tube 2 and the mounting tube 1, so as to facilitate the cleaning of the inside of the ventilation pipe. Furthermore, the outer wall of the connecting tube 2 is provided with evenly distributed mounting holes 7, which can very conveniently adjust the length of the ventilation pipe. The structure provided in the present application can simultaneously adjust the length of the ventilation pipe and disassemble and clean the ventilation pipe, thereby simplifying the structure of the ventilation pipe.

[0022] A groove 8 is provided in the mounting tube 1, and the mounting rod 6 is located in the groove 8; a stopper plate 9 fixedly sleeved on the mounting rod 6 is provided in the groove 8, and a spring 10 sleeved on the mounting rod 6 is provided in the groove 8. The spring 10 is reserved for compression during installation.

[0023] The spring 10 has a reserved compression amount during installation so as to continuously exert pressure on the limiting plate 9 , thereby increasing the stability of the installation rod 6 when inserted into the installation hole 7 .

[0024] The screw rod 12 is threadedly connected with a lifting block 13 located inside the fixed block 3, and the lifting block 13 is fixedly connected to the adjustment block 4; the adjustment block 4 has a plug hole 11, and the screw rod 12 is located in the plug hole 11. The shape of the adjustment block 4 corresponds to the cross section of the connecting pipe 2.

[0025] The setting of the lifting block 13 can drive the adjusting block 4 to slide up and down, so as to adjust the cross-sectional area of ​​the air outlet of the ventilation pipe.

[0026] Principle of the utility model

[0027] When it is necessary to disassemble the connecting tube 2 and the mounting tube 1, it is only necessary to pull the mounting rod 6 outwards, and the mounting rod 6 is disengaged from the mounting hole 7, so that the connecting tube 2 can be pulled out from the slide groove 5, and then the connecting tube 2 and the mounting tube 1 can be cleaned, which is very convenient. When it is necessary to adjust the length of the ventilation pipe, the mounting rod 6 is also pulled, and the mounting rod 6 is disengaged from the mounting hole 7, and the limit plate 9 compresses the spring 10 at the same time; but there is no need to pull out the entire connecting tube 2, so that the connecting tube 2 slides in the slide groove 5, so that different mounting holes 7 are aligned with the mounting rod 6, and the mounting rod 6 is loosened. Under the action of the rebound force of the spring 10, the mounting rod 6 is inserted into the mounting hole 7, thereby completing the re-fixation of the connecting tube 2. Therefore, the structure set in the present application can not only quickly and conveniently adjust the length of the ventilation pipe, but also quickly disassemble it for cleaning, killing two birds with one stone, and a set of structures realizes two functions, simplifying the structure of the ventilation pipe.

[0028] At the same time, the present application can also adjust the ventilation cross-section of the ventilation pipe. By turning the screw 12, the adjustment block 4 and the lifting block 13 cannot rotate due to the restriction of the connecting groove 14, and can only move in the vertical direction, thereby blocking the ventilation cross-section of the connecting pipe 2, thereby adjusting the ventilation cross-section of the ventilation pipe.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
