Description

Technical Field

[0001] The utility model relates to the technical field of connecting flanges, in particular to a connecting flange capable of freely adjusting a bolt fixing position. Background Art

[0002] Flange is also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used on the inlet and outlet of equipment to connect two devices. Flanges are used in pairs. Low-pressure pipelines can use threaded flanges, and pressures above four kilograms can use welding flanges. Flanges of different pressures have different thicknesses, and they use different bolts. When water pumps and valves are connected to pipelines, parts of these equipment are also made into corresponding flange shapes, also called flange connections.

[0003] When connecting flanges, multiple bolts are needed to bolt the two flanges together. However, when using traditional connecting flanges, the fixing holes of the two flanges must be aligned so that the bolts can pass through the fixing holes for connection. As a result, the bolts cannot be freely adjusted when they are fixed with bolts, which causes many inconveniences during the installation process and is inconvenient for workers to use. For this reason, we propose a connecting flange that can freely adjust the bolt fixing position. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a connecting flange capable of freely adjusting the fixing position of bolts, so as to solve the above problems.

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

[0006] A connecting flange capable of freely adjusting the bolt fixing position comprises a first flange plate, a flange gasket is arranged on one side of the first flange plate, a second flange plate is arranged on one side of the flange gasket, the flange gasket is located between the first flange plate and the second flange plate, a connecting component is arranged on one side of the first flange plate and the second flange plate, and an adjustment component is arranged inside the first flange plate and the second flange plate.

[0007] Preferably, the connecting assembly includes a connecting head fixedly connected to one side of the first flange and the second flange, the outside of the connecting head is provided with an external thread, and the inside of the connecting head is provided with an internal thread. Through the setting of the connecting assembly, the first flange can be connected to the second flange and the pipeline.

[0008] Preferably, arc grooves are provided on one side of the first flange and the second flange, and the number of the arc grooves is four and they are distributed at equal distances.

[0009] Preferably, the adjustment component comprises a bolt barrel arranged inside the arc groove, and the outside of the bolt barrel is fixedly connected to two symmetrically distributed sliding blocks, and the fixing position of the bolt can be adjusted by setting the adjustment component.

[0010] Preferably, the top and bottom of the inner wall of the arc-shaped groove are both provided with sliding grooves, and the two sliders are slidably connected inside the corresponding sliding grooves, and the bolt barrel is slidably connected inside the sliding grooves through the sliders, so that the bolt barrel is more stable when moving.

[0011] Compared with the prior art, the beneficial effect of the utility model is that when the bolts need to be adjusted during the process of connecting the pipeline using the first flange and the second flange, the first flange and the second flange are first installed on the corresponding pipeline through the connecting head, and the connecting head can be installed on the outside or inside of the pipeline through the external thread on the outside of the connecting head and the internal thread on the inside, and the adaptability is greatly enhanced, and it can adapt to pipelines of different models. At this time, the flange gasket is placed between the first flange and the second flange, and then the first flange and the second flange are brought close to the flange gasket and contacted with the flange gasket. The arc groove, bolt barrel, slide groove and slider allow the bolt barrel to slide inside the arc groove, thereby changing the fixed position of the bolt. The bolt barrel is slidably connected to the inside of the slide groove by the slider, so that the bolt barrel is more stable during movement. The above structure is convenient for the staff to adjust the fixed position of the bolt when using the first flange and the second flange to connect the pipeline, avoiding the disadvantages of the traditional flange that the fixing holes of the two sets of flanges must be aligned before they can be connected, the bolts cannot be freely adjusted when fixed, and the installation is inconvenient, which greatly facilitates the use of the staff.
