Description

Technical Field

[0001] The utility model relates to the technical field of flange structures, in particular to a stainless steel flange structure which is easy to connect. Background Art

[0002] Flange, also known as flange plate or flange, is a part that connects pipes to each other. It is connected to the pipe end. There are holes on the flange for bolts to connect the two flanges tightly. The flanges are sealed with gaskets. When the existing flanges are used, they are generally installed by bolts and nuts. This method often takes a long time to install and has low installation efficiency.

[0003] The Chinese patent "A stainless steel flange structure easy to connect" authorization announcement number "CN 219692535U" is tightened. When the pressure column is pressed, the spring rotates, so that the two clamping plates are separated, and then the two clamping plates can be smoothly clamped with the clamping base. After the pressure column is released, the two clamping plates are clamped with the clamping base, so that the first flange and the second flange are fixed, making the installation between the first flange and the second flange more convenient.

[0004] Although the above scheme can fix the first flange and the second flange, during installation, the four connecting bases will enter the fixing frame at the same time. Therefore, one or more workers are required to press the pressure column downward at the same time, and another worker moves the first flange to insert the connecting base into the fixing frame. As a result, multiple workers are required to cooperate to complete the installation work, which is more cumbersome.

[0005] Therefore, a stainless steel flange structure that is easy to connect is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a stainless steel flange structure that is easy to connect in order to solve the above-mentioned problem, thereby improving the problem that during installation, four connecting bases will enter the fixed frame at the same time. Therefore, one or more workers are required to press the pressure column downward at the same time, and another worker moves the first flange to insert the connecting base into the fixed frame, which results in the need for multiple workers to cooperate to complete the installation work during installation, which is a rather cumbersome problem.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a stainless steel flange structure that is easy to connect, comprising: a first flange and a second flange; a mounting mechanism, wherein the mounting mechanism is arranged at one end of the first flange for conveniently mounting the first flange and the second flange; wherein the mounting mechanism comprises a plurality of mounting rods fixedly connected to one end of the first flange, one end of the second flange is provided with mounting holes distributed in an annular shape, the inner wall of the second flange is provided with fixing holes having the same number as the mounting holes, the fixing holes are connected to the corresponding mounting holes, the inner wall of the mounting rod is slidably connected with a moving rod, and the other end of the moving rod is fixedly connected with a fixing rod.

[0008] Preferably, the mounting mechanism further comprises a bolt threadedly connected to the inner wall of the first flange, the inner wall of the first flange is provided with an annular groove, the inner wall of the annular groove is slidably connected with a moving ring, one end of the bolt passes through the annular groove and is rotatably connected with one end of the moving ring, the other end of the moving ring is fixedly connected with round rods of the same number as the mounting rods, the other end of the round rods passes through the interior of the corresponding mounting rods and is hinged with a connecting rod, the other end of the connecting rod is hinged with the bottom end of the fixed rod. By rotating the bolt, the multiple round rods are pushed to move and push the corresponding connecting rods at the same time under the action of the moving ring, so that the multiple fixing rods are moved at the same time and enter the corresponding fixing holes, which is conducive to the multiple fixing rods being connected with the corresponding fixing holes at the same time, so as to achieve the fixing of the first flange to the second flange, and the installation process is simple, and does not require the cooperation of multiple staff members to complete, thereby improving the installation efficiency of the first flange to the second flange.

[0009] Preferably, a circular ring is fixedly connected to one end of the first flange, a first annular airbag is fixedly connected to the surface of the circular ring, a mounting groove is provided at one end of the second flange, a second annular airbag is fixedly connected to one side of the inner wall of the annular groove, and a connecting pipe is connected between the first annular airbag and the second annular airbag. Inserting the first annular airbag and the circular ring into the mounting groove is conducive to increasing the contact area when the first flange is installed on the second flange, and squeezing the second annular airbag when the moving ring moves makes the first annular airbag seal the gap generated when the circular ring is connected to the mounting groove.

[0010] Preferably, one end of the first flange is fixedly connected to a limiting block, and one end of the second flange is provided with a limiting slot. The interaction between the limiting block and the limiting slot facilitates better alignment of the mounting rod with the corresponding mounting hole.

[0012] Preferably, the number of the mounting rods is the same as the number of the mounting holes, and the angle between the center points of two adjacent mounting rods is the same as the angle between the center points of two adjacent mounting holes, thereby ensuring that the positions of the mounting rods and the mounting holes correspond one to one during installation.

[0013] Preferably, the surface of the limit block is curved in an arc shape, thereby reducing the resistance when the limit block enters the limit groove.

[0014] The beneficial effects of the utility model are:

[0015] 1.

The installation process is simple and does not require the cooperation of multiple staff members, thereby improving the installation efficiency of the first flange to the second flange;

[0016] 2. When installing the first flange on the second flange, inserting the first annular airbag and the circular ring into the installation groove is beneficial to increasing the contact area when the first flange is installed on the second flange, and squeezing the second annular airbag when the moving ring moves to make the first annular airbag seal the gap generated when the circular ring is connected to the installation groove.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, a stainless steel flange structure that is easy to connect includes: a first flange 1 and a second flange 2; a mounting mechanism 3, wherein the mounting mechanism 3 for conveniently mounting the first flange 1 and the second flange 2 is arranged at one end of the first flange 1; wherein the mounting mechanism 3 includes a plurality of mounting rods 31 fixedly connected to one end of the first flange 1, one end of the second flange 2 is provided with mounting holes 32 distributed in an annular pattern, the inner wall of the second flange 2 is provided with fixing holes 33 having the same number as the mounting holes 32, the fixing holes 33 are connected to the corresponding mounting holes 32, the inner wall of the mounting rod 31 is slidably connected with a moving rod 34, and the other end of the moving rod 34 is fixedly connected with a fixing rod 35. The number of mounting rods 31 is the same as the number of mounting holes 32, and the angle between the center points of two adjacent mounting rods 31 is the same as the angle between the center points of two adjacent mounting holes 32. The other end of the mounting rod 31 is bent in an arc shape.

[0025] The inner wall diameter of the mounting hole 32 is the same as the diameter of the mounting rod 31. When installing the first flange 1 and the second flange 2, the first flange 1 and the second flange 2 are in a horizontal state, and the mounting rod 31 is inserted into the corresponding mounting hole 32, and one end of the first flange 1 is fitted with one end of the second flange 2. At this time, the fixing rod 35 is aligned with the corresponding fixing hole 33.

[0026] like Figure 2 , Figure 3 and Figure 4As shown, the mounting mechanism 3 also includes a bolt 36 threadedly connected to the inner wall of the first flange 1, an annular groove 37 is provided on the inner wall of the first flange 1, a movable ring 38 is slidably connected to the inner wall of the annular groove 37, one end of the bolt 36 passes through the annular groove 37 and is rotatably connected to one end of the movable ring 38, the other end of the movable ring 38 is fixedly connected to round rods 39 of the same number as the mounting rod 31, the other end of the round rod 39 passes through the interior of the corresponding mounting rod 31 and is hinged to a connecting rod 310, and the other end of the connecting rod 310 is hinged to the bottom end of the fixed rod 35.

[0027] When the device is in an initial state, the fixing rod 35 is retracted inside the mounting rod 31 , and does not affect the insertion of the mounting rod 31 into the mounting hole 32 .

[0028] When one end of the first flange 1 is fitted with one end of the second flange 2, the bolt 36 is rotated. When the bolt 36 is rotated, it will push the movable ring 38 to move, and the surface of the round rod 39 is slidingly connected to the inner wall of the mounting rod 31. When the movable ring 38 moves, it will push multiple round rods 39 to move at the same time. At this time, the other end of the round rod 39 will push one end of the connecting rod 310 to move horizontally, so that the angle between the connecting rod 310 and the vertical plane gradually increases, and the other end of the connecting rod 310 will push the fixing rod 35 to move out of the mounting rod 31 and enter the fixing hole 33. At this time, multiple fixing rods 35 will be simultaneously engaged with the corresponding fixing holes 33, thereby completing the installation and fixation of the first flange 1 and the second flange 2.

[0029] like Figure 2 and Figure 5 As shown, a circular ring 311 is fixedly connected to one end of the first flange 1, a first annular airbag 312 is fixedly connected to the surface of the circular ring 311, a mounting groove 313 is opened at one end of the second flange 2, a second annular airbag 314 is fixedly connected to one side of the inner wall of the annular groove 37, and a connecting pipe 315 is connected between the first annular airbag 312 and the second annular airbag 314.

[0030] When the device is in an initial state, the first annular airbag 312 and the second annular airbag 314 are in a constant pressure state.

[0031] When the mounting rod 31 is inserted into the mounting hole 32 , the circular ring 311 and the first annular airbag 312 enter the mounting groove 313 at the same time.

[0032] When the rotating bolt 36 pushes the movable ring 38 to move, the movable ring 38 will contact and squeeze the second annular airbag 314. When the second annular airbag 314 is squeezed, the gas in the second annular airbag 314 will enter the first annular airbag 312 through the connecting tube 315, causing the first annular airbag 312 to expand, and the surface of the first annular airbag 312 to fit the inner wall of the mounting groove 313, thereby sealing the gap generated when the ring 311 is connected to the mounting groove 313.

[0033] like Figure 2 As shown, one end of the first flange 1 is fixedly connected to a limiting block 316, and one end of the second flange 2 is provided with a limiting groove 317. The surface of the limiting block 316 is curved in an arc shape. The size and shape of the inner wall of the limiting groove 317 are the same as those of the limiting block 316. When the first flange 1 and the second flange 2 are installed, the limiting block 316 and the limiting groove 317 are in the same horizontal plane. At this time, the mounting rod 31 and the corresponding mounting hole 32 are in the same horizontal plane. The limiting block 316 is horizontally inserted into the limiting groove 317, and at this time, multiple mounting rods 31 will enter the corresponding mounting holes 32.

[0034] When the utility model is in use, when installing the first flange 1 and the second flange 2, the limit block 316 and the limit groove 317 are in the same horizontal plane, and the limit block 316 is horizontally inserted into the limit groove 317. At this time, multiple mounting rods 31 will enter the corresponding mounting holes 32, and make one end of the first flange 1 fit with one end of the second flange 2. At this time, the fixing rod 35 is aligned with the corresponding fixing hole 33, and the bolt 36 is turned to push the movable ring 38 to move. When the movable ring 38 moves, it will push multiple round rods 39 to move at the same time. At this time, the other end of the round rod 39 will push one end of the connecting rod 310 to move horizontally, so that the other end of the connecting rod 310 pushes the fixing rod 35 to move out of the mounting rod 31 and enter the fixing hole 33. At this time, multiple fixing rods 35 will be clamped with the corresponding fixing holes 33 at the same time, thereby completing the installation and fixation of the first flange 1 and the second flange 2.

[0035] In the process of rotating the bolt 36 to push the movable ring 38 to move, the movable ring 38 will contact and squeeze the second annular airbag 314. After being squeezed, the gas in the second annular airbag 314 will enter the first annular airbag 312 through the connecting tube 315, causing the first annular airbag 312 to expand, and the surface of the first annular airbag 312 to fit the inner wall of the mounting groove 313, thereby sealing the gap generated when the ring 311 is connected to the mounting groove 313.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
