[0030] Example 1

[0031] Reference Figures 1 to 8 , which is the first embodiment of the present invention, and provides a fixing mechanism for a stainless steel pipe flange, which can achieve the effect of automatically sealing the pipeline during disassembly, and its supporting component 100 includes a first pipeline 101, a first flange 102 arranged on the first pipeline 101, a second pipeline 103 arranged on the right side of the first pipeline 101, and a second flange 104 arranged on the second pipeline 103; the mounting component 200 includes a sealing component 201 arranged on the first flange 102 and the second flange 104, a closing component 202 arranged on the first flange 102, a toggle component 203 arranged on the closing component 202, a limit component 204 arranged on the second flange 104, and a power component 205 arranged on the first flange 102; the anti-loosening component 300 includes a one-way component 301 arranged on the power component 205, an elastic component 302 arranged on the one-way component 301, a reset component 303 arranged on the elastic component 302, and an extension component 304 arranged on the power component 205.

[0032] Specifically, the first pipe 101 is connected to the water inlet, the second pipe 103 is connected to the water outlet, the first flange 102 is fixedly connected to the first pipe 101, and the second pipe 103 is fixedly connected to the second flange 104. The flanges here are prior art and are not described here.

[0033] Furthermore, the sealing component 201 includes an inner groove 201a arranged on the first flange 102 and the second flange 104, and a sealing ring 201b is fixedly connected in the inner groove 201a; the closing component 202 includes a cavity 202a arranged in the first flange 102, a first sealing ring 202b is fixedly connected to the sealing ring 201b, five rotating shafts 202c are rotatably connected to the first sealing ring 202b, and a transmission plate 202d is rotatably connected to the five rotating shafts 202c. The transmission plate 202d is provided with a first arc edge 202e, a second arc edge 202f and a third arc edge 202g. The five transmission plates 202d are arranged along the circumference of the first sealing ring 202b, and the first arc edge 202e on the transmission plate 202d cooperates with the second arc edge 202f on the adjacent transmission plate 202d, and the five transmission plates 202d are combined into a closed disc.

[0034] Among them, the inner groove 201a is annular, and the diameter of the inner groove 201a is larger than the diameter of the first pipe 101, the sealing ring 201b is annular and cooperates with the inner groove 201a, the sealing ring 201b here is in the inner groove 201a, and when the two sealing rings 201b are against each other, the first flange 102 and the second flange 104 can be sealed, and the side wall of the first sealing ring 202b is against the side wall of the transmission plate 202d, so that when the transmission plate 202d is rotated to close, the first pipe 101 can be closed.

[0035] Preferably, the toggle assembly 203 includes a second sealing ring 203a rotatably connected to the inner wall of the cavity 202a, the second sealing ring 203a is provided with five guide grooves 203b, a guide column 203c is slidably connected in the guide groove 203b, a slant plate 203d is rotatably connected to the guide column 203c, an epitaxial block is fixedly connected to the transmission plate 202d, the epitaxial block is rotatably connected to the support shaft 203e, the support shaft 203e is fixedly connected to the slant plate 203d, the epitaxial block and the rotating shaft 202c are respectively arranged at the two ends of the third arc edge 202g; the limit assembly 204 includes five plug plates 204a fixedly connected to the second flange 104, and the first flange 102 There are five sockets 204b that match with the plug plate 204a, the plug plate 204a is provided with a slot 204c that matches with the third arc edge 202g, the socket 204b is provided with an extension slot 204d, both ends of the extension slot 204d are provided with a sealing cavity 204e, a transmission shaft 204f is rotatably connected in the sealing cavity 204e, a torsion spring 204g is provided on the transmission shaft 204f, a support shaft 203e passes through the sealing cavity 204e and is sealed and rotatably connected with the sealing cavity 204e, a sealing block 204h that matches with the socket 204b is fixedly connected to the transmission shaft 204f, and a mounting port 204i that matches with the plug plate 204a is provided on the second sealing ring 203a.

[0036] It should be noted that an anti-slip block is also provided on the guide column 203c, and an anti-slip groove cooperating with the anti-slip block is provided in the guide groove 203b, so as to prevent the guide column 203c from being detached in the anti-slip groove. The second sealing ring 203a and the transmission plate 202d are arranged in a left-right offset manner, so that when the transmission plate 202d moves, it will not collide with the second sealing ring 203a, ensuring that the transmission plate 202d can move. When the sealing ring 201b on the first flange 102 is in contact with the transmission plate 202d, the sealing ring 201b on the first flange 102 is in contact with the transmission plate 202d. When the sealing ring 201b on the second flange 104 is in contact, the card slot 204c is directly opposite to the third arc edge 202g on the transmission plate 202d. The T-shaped plate 205b here is misaligned with the cavity 202a, so that no water will flow out from the arc-shaped opening 205a. There is a section on the extended groove 204d here that is set to be arc-shaped, and this arc section cooperates with the sealing block 204h, so that when the sealing block 204h rotates, it will not get stuck with the inner wall of the extended groove 204d.

[0037] During use, when the first pipe 101 and the second pipe 103 are separated, the transmission plate 202d is combined into a disc shape to close the first pipe 101, and the sealing block 204h seals the socket 204b, so that when docking with the second pipe 103, it is not necessary to close the valve specifically to ensure that water does not leak out, and then the first flange 102 on the first pipe 101 is abutted against the flange on the second pipe 103. In this process, the plug plate 204a is inserted into the socket 204b, the sealing block 204h is pushed open, and then the plug plate 204a is inserted into the socket 204b to seal the socket 204b. When the end faces of the first flange 102 and the second flange 104 are abutted, the T-shaped plate 205b is rotated, and the arc-shaped opening 205a guides the T-shaped plate 205b. When the T-shaped plate 205b moves, it can drive the second sealing ring 203a moves clockwise (when viewed from the left end, that is, the direction of the water source, the same below). When the second sealing ring 203a rotates clockwise, it can drive the guide groove 203b to move, thereby driving the guide column 203c in the guide groove 203b to move, so that the transmission plate 202d rotates around the rotating shaft 202c, so that the first arc edge 202e and the second arc edge 202f on the two adjacent transmission plates 202d are separated. When the first arc edge 202e and the second arc edge 202f are separated, the third arc edge 202g can also be inserted into the card slot 204c to limit the insertion plate 204a, thereby preventing the insertion plate 204a from being separated from the second flange 104, thereby achieving the fixation between the first flange 102 and the second flange 104. When the first flange 102 and the second flange 104 need to be disassembled, the T-shaped plate 205b can be reversed.

[0038] In summary, when disassembling the first flange 102 and the second flange 104, the first arc edge 202e and the second arc edge 202f on the two adjacent transmission plates 202d can be matched to seal the first pipe 101 to prevent water from flowing out, so that the pipes can be connected without closing the valve, and when fixing the first flange 102 and the second flange 104, it is only necessary to move the T-shaped plate 205b to fix them through transmission, which is more convenient to use.

[0039] Example 2

[0040] Reference Figure 2-3 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an anti-loosening component 300 of a fixing mechanism for a stainless steel pipe flange, which solves the problem of how to prevent the T-shaped plate 205b from automatically resetting. It includes a one-way component 301, including a plurality of strip grooves 301a arranged on the side wall of the arc-shaped opening 205a, and a mounting box 301b is fixedly connected to the T-shaped plate 205b. The mounting box 301b is provided with an insert block 301c that cooperates with the strip groove 301a, and the insert block 301c is provided with a cutting edge 301d that cooperates with the strip groove 301a.

[0041] Furthermore, the elastic component 302 includes a baffle 302a arranged on the installation box 301b, a connecting port 302b is provided on the installation box 301b, an insert block 301c passes through the connecting port 302b and is fixedly connected to the baffle 302a, and the baffle 302a is elastically connected to the inner wall of the installation box 301b through a spring 302c; the reset component 303 includes a through port 303a arranged on the installation box 301b, a transmission rod 303b passing through the through port 303a is fixedly connected to the baffle 302a, a rotating block 303c is rotatably connected to the transmission rod 303b, and two stop grooves 303d cooperating with the rotating block 303c are provided on the T-shaped plate 205b.

[0042] It should be noted that the setting of the cutting edge 301d is such that when the T-shaped plate 205b is turned clockwise, the strip groove 301a and the insert block 301c will not be stuck. When the rotating block 303c is in the upper stop groove 303d, the insert block 301c at the lower end is separated from the strip groove 301a. When the rotating block 303c is in the lower stop groove 303d, the insert block 301c extends into the strip groove 301a, thereby adjusting the position of the insert block 301c.

[0043] When in use, first, the rotating block 303c is in the stop groove 303d at the lower end. At this time, when the T-shaped plate 205b is moved clockwise, the insert block 301c also moves clockwise. At this time, the cutting edge 301d cooperates with the strip groove 301a, so that the movement of the insert block 301c is not hindered. In the counterclockwise direction, the vertical edge of the insert block 301c abuts against the inner wall of the strip groove 301a, so that the insert block 301c can only rotate clockwise but not counterclockwise, so that the T-shaped plate 205b will not automatically reset counterclockwise, ensuring the stability of the T-shaped plate 205b. When the T-shaped plate 205b needs to be reset, the rotating block 303c only needs to be moved so that the rotating block 303c is misaligned with the stop groove 303d at the lower end, and then the transmission rod 303b is pulled to move the baffle 302a, and the insert block 301c moves to the upper side of the strip groove 301a. At this time, the rotating block 303c is opposite to the stop groove 303d at the upper end, and then the rotating block 303c is rotated in the opposite direction so that the rotating block 303c is stuck in the stop groove 303d at the upper end, so that the T-shaped plate 205b can be freely moved to reset the T-shaped plate 205b.

[0044] In summary, when the T-shaped plate 205b is moved, the plug block 301c can also be driven to cooperate with different strip grooves 301a. Since the plug block 301c cannot automatically reset counterclockwise after cooperating with the strip groove 301a, the T-shaped plate 205b will not automatically reset, thereby ensuring the stability of the fixation between the first flange 102 and the second flange 104.

[0045] Example 3

[0046] Reference Figure 2-3 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an extension component 304 of the fixing mechanism for the stainless steel pipe flange, which solves the problem of how to save more effort when rotating the T-shaped plate 205b. It includes a receiving groove 304a arranged on the T-shaped plate 205b, and an extension bar 304b is slidably connected in the receiving groove 304a. The extension bar 304b is provided with a threaded hole 304c, and the T-shaped plate 205b is provided with a plurality of circular holes 304d matching the threaded hole 304c. The circular hole 304d is provided with a screw rod 304e matching the threaded hole 304c, and the outer end of the screw rod 304e is fixedly connected to a turntable 304f, and a plurality of anti-slip particles 304g are fixedly connected to the side wall of the turntable 304f.

[0047] Specifically, due to the problem of water squeezing, the movement of the transmission plate 202d may encounter resistance, which makes the movement of the T-shaped plate 205b more difficult, and thus it is necessary to extend the lever arm. There are multiple circular holes 304d here, and there is only one threaded hole 304c. The threaded hole 304c is directly opposite to different circular holes 304d, and then the screw 304e is inserted to adjust the overall length of the T-shaped plate 205b.

[0048] During use, when the length of the T-shaped plate 205b needs to be adjusted, it is only necessary to rotate the turntable 304f. The multiple anti-slip particles 304g here can prevent the hand from slipping when the turntable 304f is rotated. When the turntable 304f is rotated, the screw rod 304e can be separated from the threaded hole 304c, and then the extension bar 304b can be pulled to extend the length of the T-shaped plate 205b, and then the round hole 304d is made to face the threaded hole 304c, and then the turntable 304f is reversed to make the screw rod 304e inserted into the threaded hole 304c, so that the position of the extension bar 304b is fixed, and then the extension bar 304b can be moved to move the T-shaped plate 205b. Moreover, due to the increase in the overall length, the force arm is increased, making the rotation of the T-shaped plate 205b more labor-saving.

[0049] In summary, when the T-shaped plate 205b is moved, the extension bar 304b can also be pulled, which is equivalent to extending the length of the T-shaped plate 205b, which is equivalent to increasing the force arm, making the movement of the T-shaped plate 205b more labor-saving and making it easier for workers to rotate the second sealing ring 203a.
