Description

Technical Field

[0001] This invention belongs to the field of flange technology, and more specifically, relates to a flange. Background Technology

[0002] A flange is a component used to connect two pipes. It typically consists of two flange plates, each attached to one of the pipe ends. Existing flanges generally have holes in the flange plates for bolts to connect the two flange plates.

[0003] However, when connecting two flanges, multiple sets of bolts need to be threaded through one flange at a time, which is extremely cumbersome and reduces work efficiency. Summary of the Invention

[0004] This invention provides a flange that enables quick connection of two flanges, improving work efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a flange is provided, comprising a first disc body, a second disc body, an insert rod, and a hook. The first disc body is used to connect to the end of a first connecting pipe, and a first through hole is provided through the first disc body. The second disc body is used to connect to the end of a second connecting pipe, and a second through hole corresponding to the first through hole is provided through the second disc body. The insert rod is connected to the outer periphery of the second connecting pipe and extends along the axial direction of the second connecting pipe. The insert rod passes through the second through hole and the first through hole, and a circumferentially extending groove is provided at the outer end of the insert rod. The hook is hinged to the outer periphery of the first connecting pipe. The swing end of the hook has a slot for accommodating the insert rod. The hook can swing vertically to hook onto the inner wall of the groove away from the second disc body to lock the relative position of the first disc body and the second disc body.

[0006] In one possible implementation, the hook includes a first hinge rod and a hook. The first hinge rod is hinged to the outer end of the first connecting tube and extends outward. The hook is connected to the first hinge rod, and a slot is provided at the outer end of the hook. The hook is used to hook onto the inner wall of the groove away from the second disc.

[0007] In some embodiments, a first threaded sleeve is threaded around the outer periphery of the first connecting pipe, a rotating ring is rotatably fitted around the outer periphery of the first threaded sleeve, and a second hinge rod is provided between the first hinge rod and the rotating ring. The first threaded sleeve can drive the rotating ring to move towards the side of the first disc body and drive the first hinge rod to swing vertically so that the hook is hooked on the groove away from the inner sidewall of the second disc body.

[0008] In some embodiments, the outer end of the first connecting pipe is provided with a mounting platform that protrudes outward, the first hinge rod is hinged to the outer peripheral wall of the mounting platform, and the first threaded sleeve is located on the side of the mounting platform away from the first disc body.

[0009] In some embodiments, the hook includes a horizontal portion connected to the first hinge rod and a bent portion connected to the outer end of the horizontal portion. The bent portion is parallel to the first hinge rod and extends toward the axial side of the first connecting tube, and a slot is provided at the extended end of the bent portion.

[0010] In one possible implementation, the insertion rod is slidably engaged with the first disc and the second disc respectively, and the outer periphery of the second connecting tube is fixedly fitted with the mounting disc. The mounting disc is axially permeated with a second threaded sleeve, which is rotatably connected to the mounting disc and is threaded on the outer periphery of the insertion rod. The second threaded sleeve can rotate to drive the insertion rod to move axially.

[0011] In some embodiments, a plurality of insert rods are arranged circumferentially on the second connecting tube, and a plurality of second threaded sleeves are also provided, each corresponding to one of the insert rods. The second connecting tube is provided with a drive assembly for driving the second threaded sleeves.

[0012] In some embodiments, the drive assembly includes a rotating sleeve, a first gear, and a second gear. The rotating sleeve is rotatably sleeved on the outer periphery of the second connecting pipe; the first gear is fixedly sleeved on the outer periphery of the rotating sleeve; the second gear is fixedly sleeved on the outer periphery of the second threaded sleeve and meshes with the first gear; the rotating sleeve is used to drive the first gear to rotate so that the second gear drives the second threaded sleeve to rotate.

[0013] In some embodiments, the inner peripheral wall of the first through hole is provided with an axially extending first positioning groove, the inner peripheral wall of the second through hole is provided with an axially extending second positioning groove, the first positioning groove and the second positioning groove are axially corresponding, and the outer peripheral wall of the insert rod is provided with an axially extending positioning strip that slides with the first positioning groove and the second positioning groove respectively.

[0014] In some embodiments, several positioning bars are arranged at intervals around the circumference of the insert rod.

[0015] Compared with the prior art, the flange provided in this embodiment can bring the first and second discs close to each other when it is necessary to connect the first disc and the second disc, so that the insertion rod passes through the first through hole, and then the hook is swung vertically so that it is hooked on the inner wall of the groove away from the second disc to lock the relative position of the first disc and the second disc, thereby realizing the rapid connection of the first disc and the second disc and improving work efficiency.

[0024] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0026] Please see Figures 1 to 5 The flange provided by the present invention will now be described. The flange includes a first disc 10, a second disc 20, an insert rod 30, and a hook 40. The first disc 10 is used to connect to the end of the first connecting pipe 1, and a first through hole 11 is provided through the first disc 10. The second disc 20 is used to connect to the end of the second connecting pipe 2, and a second through hole 21 corresponding to the first through hole 11 is provided through the second disc 20. The insert rod 30 is connected to the outer periphery of the second connecting pipe 2 and extends along the axial direction of the second connecting pipe 2. The insert rod 30 is provided through the second through hole 21 and the first through hole 11. The outer end of the insert rod 30 is provided with a circumferentially extending groove 31. The hook 40 is hinged to the outer periphery of the first connecting pipe 1. The swing end of the hook 40 has a slot 423 for accommodating the insert rod 30. The hook 40 can swing vertically to hook onto the inner side wall of the groove 31 away from the second disc 20 to lock the relative position of the first disc 10 and the second disc 20.

[0027] The outer end of the insert rod 30 is the end closest to the hook 40.

[0028] This application provides a flange in which the insertion rod 30 is pre-inserted into the second through hole 21 during actual use. When it is necessary to connect the first disc 10 and the second disc 20, they are brought close together so that the insertion rod 30 passes through the first through hole 11. Then, the hook 40 is swung vertically until it hooks onto the inner wall of the groove 31 away from the second disc 20, thus locking the relative position of the first disc 10 and the second disc 20 (at this time, the insertion rod 30 is also located in the slot 423). This achieves a quick connection between the first disc 10 and the second disc 20, improving work efficiency. Because the hook 40 exerts a squeezing and tightening effect on the inner wall of the groove 31 towards the hook 40 during the vertical swing and hooking process, the sealing between the first disc 10 and the second disc 20 is improved.

[0029] Compared with the prior art, the flange provided in this embodiment can bring the first disc 10 and the second disc 20 closer together when they need to be connected, so that the insertion rod 30 passes through the first through hole 11, and then the hook 40 is swung vertically until it hooks onto the inner wall of the groove 31 away from the second disc 20 to lock the relative position of the first disc 10 and the second disc 20. This achieves a quick connection between the first disc 10 and the second disc 20 and improves work efficiency.

[0030] In one possible implementation, the hook and hanger 40 described above adopts the following... Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The hook 40 includes a first hinge rod 41 and a hook 42. The first hinge rod 41 is hinged to the outer end of the first connecting tube 1 and extends outward. The hook 42 is connected to the first hinge rod 41. The slot 423 is provided at the outer end of the hook 42. The hook 42 is used to hook onto the inner side wall of the groove 31 away from the second disc 20.

[0031] Specifically, the hook 42 is used to hook onto the inner wall of the groove 31 away from the second disc 20 (within the groove 31). The slot 423 is designed to avoid the insertion rod 30, thereby enhancing the hooking stability between the hook 42 and the insertion rod 30. After the hook 42 is hooked onto the inner wall of the groove 31 away from the second disc 20, the first hinge rod 41 tends to be vertical, and at this time, the insertion rod 30 is radially close to the hinge point between the first hinge rod 41 and the first connecting tube 1, thus achieving a stable hooking state.

[0032] During disassembly, simply swing the first hinge rod 41 away from the first disc 10 to disengage the hook 42 from the groove 31, thereby releasing the lock of the first disc 10 and the second disc 20 and separating the first disc 10 and the second disc 20, thus improving disassembly efficiency.

[0033] In some embodiments, see Figure 1 and Figure 2 The outer periphery of the first connecting pipe 1 is threaded with a first threaded sleeve 50, and the outer periphery of the first threaded sleeve 50 is provided with a rotating ring 51. A second hinge rod 52 is provided between the first hinge rod 41 and the rotating ring 51. The first threaded sleeve 50 can drive the rotating ring 51 to move towards the first disc 10 and drive the first hinge rod 41 to swing vertically so that the hook 42 is hooked on the groove 31 away from the inner wall of the second disc 20.

[0034] Specifically, one end of the second hinge rod 52 is hinged to the extension end of the first hinge rod 41, and the other end is hinged to the swivel ring 51. After the first disc 10 and the second disc 20 come into contact, the first threaded sleeve 50 is rotated to approach the first disc 10. The swivel ring 51 applies force to the second hinge rod 52 to push the first hinge rod 41 to swing vertically, so that the hook 42 is hooked onto the inner wall of the groove 31 away from the second disc 20, thereby locking the relative position of the first disc 10 and the second disc 20 and improving the stability of the connection between the first disc 10 and the second disc 20.

[0035] During disassembly, simply rotate the first threaded sleeve 50 away from the first disc body 10, causing the second hinge rod 52 to pull the first hinge rod 41 to swing away from the first disc body 10, thereby disengaging the hook 42 from the groove 31, thus releasing the lock between the first disc body 10 and the second disc body 20, separating the first disc body 10 and the second disc body 20, and improving disassembly efficiency.

[0036] In some embodiments, see Figure 1 and Figure 2 The outer end of the first connecting pipe 1 is provided with a mounting platform 53 that protrudes outward. The first hinge rod 41 is hinged to the outer peripheral wall of the mounting platform 53, and the first threaded sleeve 50 is located on the side of the mounting platform 53 away from the first disc body 10.

[0037] Specifically, the mounting platform 53 not only facilitates the installation of the first hinge rod 41, but also limits the first threaded sleeve 50. When the first threaded sleeve 50 abuts against the mounting platform 53, the hook 42 is hooked onto the inner wall of the groove 31 away from the second disc 20, thus improving practicality.

[0038] In some embodiments, see Figure 1 , Figure 2 and Figure 5The hook 42 includes a horizontal portion 421 connected to the first hinge rod 41 and a bent portion 422 connected to the outer end of the horizontal portion 421. The bent portion 422 is parallel to the first hinge rod 41 and extends toward the axial side of the first connecting tube 1. A slot 423 is provided at the extended end of the bent portion 422.

[0039] Specifically, the inner end of the bent portion 422 is as follows: Figure 1 In the state shown, the horizontal part 421 near the end of the first connecting tube 1 is set perpendicular to the first hinge rod 41. This arrangement of the hook 42 ensures that the hook 42 and the insert rod 30 are in the optimal hooking state when the first hinge rod 41 is in the vertical state.

[0040] After the bent portion 422 is hooked onto the inner wall of the groove 31 away from the second disc 20, the first hinge rod 41 tends to be vertical, and at this time the insertion rod 30 is close to the hinge point between the first hinge rod 41 and the first connecting pipe 1 in the radial direction of the first connecting pipe 1, thus being in a stable hooked state.

[0041] During disassembly, simply swing the first hinge rod 41 away from the first disc 10 to disengage the bent part 422 from the groove 31, thereby releasing the lock of the first disc 10 and the second disc 20 and separating the first disc 10 and the second disc 20, thus improving disassembly efficiency.

[0042] In one possible implementation, the aforementioned insertion rod 30 adopts as follows: Figure 1 and Figure 4 The structure shown is described in the following document. Figure 1 and Figure 4 The insertion rod 30 is slidably engaged with the first disc 10 and the second disc 20 respectively. The outer periphery of the second connecting pipe 2 is fixedly sleeved with the mounting disc 61. The mounting disc 61 is axially penetrated by the second threaded sleeve 60. The second threaded sleeve 60 is rotatably connected to the mounting disc 61 and is threadedly sleeved on the outer periphery of the insertion rod 30. The second threaded sleeve 60 can rotate to drive the insertion rod 30 to move axially.

[0043] Specifically, the mounting plate 61 facilitates the installation of the second threaded sleeve 60. After the hook 40 is hooked onto the inner wall of the groove 31 away from the second disc body 20, the second threaded sleeve 60 can be rotated to move the outer end of the insertion rod 30 closer to the first disc body 10, thereby further enhancing the tension between the hook 40 and the insertion rod 30, and also enhancing the sealing between the first disc body 10 and the second disc body 20.

[0044] During disassembly, first rotate the second threaded sleeve 60 to move the outer end of the insertion rod 30 away from the first disc 10, reducing the tension between the insertion rod 30 and the hook 40. Then, swing the hook 40 vertically to separate it from the groove 31, which will allow the hook 40 to disengage from the insertion rod 30, thereby releasing the lock between the first disc 10 and the second disc 20 and separating the first disc 10 and the second disc 20, thus improving the disassembly efficiency.

[0045] In some embodiments, see Figure 1 and Figure 4 Several insertion rods 30 are arranged in the circumferential direction of the second connecting pipe 2, and several second threaded sleeves 60 are also provided, which are arranged one-to-one with the insertion rods 30. The second connecting pipe 2 is provided with a drive assembly 70 for driving the second threaded sleeves 60.

[0046] Specifically, a number of hooks 40 are also provided at intervals around the first connecting pipe 1, and the number of hooks 40 corresponds one-to-one with the number of insert rods 30.

[0047] The drive assembly 70 can drive several second threaded sleeves 60 to rotate simultaneously. Even if the insert rods 30 move simultaneously, the hooking force between each insert rod 30 and each corresponding hook 40 is the same, ensuring the stability of the connection between the first disc 10 and the second disc 20.

[0048] Optionally, the drive assembly 70 includes a rotating sleeve 73, a first gear 72, and a second gear 71. The rotating sleeve 73 is disposed on the outer periphery of the second connecting pipe 2; the first gear 72 is fixedly sleeved on the outer periphery of the rotating sleeve 73; and the second gear 71 is fixedly sleeved on the outer periphery of the second threaded sleeve 60 and meshes with the first gear 72.

[0049] Optionally, the drive assembly 70 includes a rotating sleeve, a drive disk, a gear ring, and a third gear. The rotating sleeve 73 is disposed on the outer periphery of the second connecting pipe 2. The drive disk is fixedly disposed on the outer periphery of the rotating sleeve and is located near the end of the second threaded sleeve 60 away from the second disk body 20. The gear ring is connected to the end face of the drive disk near the second threaded sleeve 60, and teeth are provided on the inner peripheral wall of the gear ring. The third gear is fixedly disposed on the outer periphery of the second threaded sleeve 60 and meshes with the gear ring.

[0050] In some embodiments, see Figure 1 The drive assembly 70 includes a rotating sleeve 73, a first gear 72, and a second gear 71. The rotating sleeve 73 is disposed on the outer periphery of the second connecting pipe 2. The first gear 72 is fixedly sleeved on the outer periphery of the rotating sleeve 73. The second gear 71 is fixedly sleeved on the outer periphery of the second threaded sleeve 60 and meshes with the first gear 72. The rotating sleeve 73 is used to drive the first gear 72 to rotate so that the second gear 71 drives the second threaded sleeve 60 to rotate.

[0051] Specifically, after the hook 40 is hooked onto the inner wall of the groove 31 away from the second disc 20, the rotatable sleeve 73 drives the second threaded sleeve 60 to rotate through the transmission of the first gear 72 and the second gear 71, so that the outer end of the insertion rod 30 moves closer to the first disc 10, thereby further enhancing the stability of the hook 40 and the insertion rod 30, and also enhancing the sealing between the first disc 10 and the second disc 20.

[0052] During disassembly, first rotate the rotating sleeve 73 to drive the second threaded sleeve 60 to rotate, causing the outer end of the insertion rod 30 to move away from the first disc 10, reducing the contact force between the insertion rod 30 and the hook 40. Then, swing the hook 40 vertically to the outside of the groove 31, so that the hook 40 can be disengaged from the insertion rod 30, thereby releasing the lock of the first disc 10 and the second disc 20, separating the first disc 10 and the second disc 20, and improving the disassembly efficiency.

[0053] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The inner peripheral wall of the first through hole 11 is provided with an axially extending first positioning groove 111, and the inner peripheral wall of the second through hole 21 is provided with an axially extending second positioning groove 211. The first positioning groove 111 and the second positioning groove 211 are axially corresponding. The outer peripheral wall of the insertion rod 30 is provided with an axially extending positioning strip 32 that slides with the first positioning groove 111 and the second positioning groove 211 respectively.

[0054] Specifically, by limiting the engagement of the positioning bar 32 with the first positioning groove 111 and the second positioning groove 211, the rotation of the insertion rod 30 is prevented, so that the insertion rod 30 can only move along the axial direction of the second disc 20, which facilitates the sliding engagement adjustment of the insertion rod 30 with the first disc 10 and the second disc 20.

[0055] In some embodiments, see Figure 1 and Figure 4 The positioning strips 32 are arranged at intervals around the circumference of the insert rod 30.

[0056] Specifically, the arrangement of multiple positioning bars 32 further enhances the stability of the sliding connection between the insertion rod 30 and the first disc 10 and the second disc 20.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
