Description

Technical Field

[0001] This utility model relates to the field of flange installation technology, and more specifically to a flange device that can be quickly disassembled. Background Technology

[0002] A flange, also called a flange plate or flange, is a component used to connect pipes to each other, for connecting the pipe ends; flanges are also used on equipment inlets and outlets to connect two pieces of equipment, such as speed reducer flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts connected together as a combined sealing structure.

[0003] Currently, when connecting and installing two flanges, the usual method is to insert bolts into the flange holes at the corresponding positions, and then use nuts to lock the bolts to achieve a locking connection between the two flanges. However, when it is necessary to disassemble and repair the flanges, the nuts and bolts must be completely separated, and the bolts must be removed from the flange holes before the flanges can be disassembled. This disassembly process is quite cumbersome.

[0004] In view of this, the present invention proposes a flange device that can be quickly disassembled to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a flange device that can be quickly disassembled, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a flange device that can be quickly disassembled, including a first flange and a second flange, both of which have flange holes on their surfaces, and a connecting mechanism for connecting the first flange and the second flange is provided between the two flange holes.

[0007] The connecting mechanism includes a pin inserted into the flange hole. The pin has a first threaded section on its top side, and a locking nut is threaded onto the surface of the first threaded section. The locking nut abuts against the upper surface of the first flange. A telescopic groove is provided on the side of the pin near the bottom. A locking block is slidably connected inside the telescopic groove. A circular groove is provided on the top side of the locking block, and a ball is movably installed inside the circular groove. The ball abuts against the lower surface of the second flange.

[0008] Furthermore, a guide slope is provided at the bottom end of the block on the side away from the pin. When the pin is inserted into the flange hole, the guide slope slides in contact with the inner wall of the flange hole.

[0009] As a further description of the above technical solution: by setting a guide ramp, the guide ramp can slide in contact with the inner wall of the flange hole, and the pin can be quickly inserted into the flange hole.

[0010] Furthermore, a limiting groove is formed on the inner wall of the telescopic groove, and a limiting slide rod is fixedly installed on the inner wall of the limiting groove. The locking block is slidably connected to the surface of the limiting slide rod.

[0011] As a further description of the above technical solution: by setting a limiting slide bar, the extension amount and movement path of the locking block can be limited, so as to avoid the locking block from disengaging from the pin or tilting.

[0012] Furthermore, an ejector spring is fixedly installed on the inner wall of the limiting groove, and the other end of the ejector spring abuts against the side wall of the locking block. The ejector spring drives the locking block to move outward of the telescopic groove.

[0013] As a further description of the above technical solution: by setting an ejector spring, the block can be continuously supported, so that the block remains extended out of the telescopic groove.

[0014] Furthermore, a second threaded section is formed on the surface of the pin near the bottom side, and a release ring is threadedly connected to the surface of the second threaded section. The top end of the release ring is slidably connected to the guide inclined surface. The outer diameter of the release ring is smaller than the inner diameter of the flange hole. Several anti-slip protrusions are evenly formed in a circumferential array on the surface of the release ring.

[0015] As a further description of the above technical solution: by setting a release ring and anti-slip protrusions, by rotating the release ring and utilizing the sliding between the release ring and the guide slope, the locking block can be conveniently put into the telescopic groove, quickly and easily canceling the locking effect between the locking block and the flange, and completing the disassembly action.

[0016] Furthermore, the upper side of the first threaded section is threaded with an anti-loosening nut, which abuts against the upper side of the locking nut.

[0017] As a further description of the above technical solution: by setting an anti-loosening nut, the locking effect of the locking nut can be improved, and the locking nut can be prevented from loosening during use.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. Compared with existing technologies, this quick-disassembly flange device, when connecting and installing the first and second flanges, inserts the pin from top to bottom into the flange hole, keeping the lock nut positioned on the surface of the first thread section. Then, the locking block is pulled out from the telescopic groove, and the lock nut is continued to be screwed. The lock nut abuts against the upper surface of the first flange, and the balls and locking block abut against the lower surface of the second flange, thus achieving the purpose of connecting and installing the two flanges. When it is necessary to disassemble the two flanges, the rolling friction effect of the balls quickly pushes the locking block into the telescopic groove, allowing the pin to be quickly removed from the flange hole, completing the flange disassembly. The entire disassembly and installation process does not require completely separating the lock nut from the pin, reducing the number of turns and time required to turn the lock nut, thereby improving the convenience of installation and disassembly.

[0020] 2. Compared with existing technologies, this quick-disassembly flange device, by setting a guide ramp, allows for rapid insertion of the pin into the flange hole through sliding contact between the guide ramp and the inner wall of the flange hole; by setting a limiting slide bar, it restricts the extension and movement path of the locking block, preventing the locking block from detaching from the pin or tilting; by setting an ejection spring, it continuously supports the locking block, keeping it extended out of the telescopic groove; by setting a release ring and anti-slip protrusion, rotating the release ring and sliding it against the guide ramp allows the locking block to be easily retracted into the telescopic groove, quickly and easily releasing the locking effect between the locking block and the flange, completing the disassembly action; by setting an anti-loosening nut, it improves the locking effect of the locking nut, preventing the locking nut from loosening during use.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The quick-disassembly flange device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1 to 3 This utility model provides a flange device that can be quickly disassembled, including a first flange 1 and a second flange 2. Both the first flange 1 and the second flange 2 have flange holes 3 on their surfaces, and a connecting mechanism 4 for connecting the first flange 1 and the second flange 2 is provided between the two flange holes 3.

[0027] The connecting mechanism 4 includes a pin 401, which is inserted into the flange hole 3. A first threaded section 4013 is provided on the top side of the pin 401, and a locking nut 402 is threadedly connected to the surface of the first threaded section 4013. The locking nut 402 abuts against the upper surface of the first flange 1. A telescopic groove 403 is provided on the side of the pin 401 near the bottom, and a locking block 404 is slidably connected inside the telescopic groove 403.

[0028] The inner wall of the expansion groove 403 is provided with a limiting groove, and a limiting slide rod 407 is fixedly installed on the inner wall of the limiting groove. The locking block 404 is slidably connected to the surface of the limiting slide rod 407.

[0029] By setting the limit slide bar 407, the extension amount and movement path of the locking block 404 can be limited, so as to prevent the locking block 404 from disengaging from the pin 401 or from tilting.

[0030] An ejector spring 408 is fixedly installed on the inner wall of the limiting groove. The other end of the ejector spring 408 abuts against the side wall of the locking block 404. The ejector spring 408 drives the locking block 404 to move to the outside of the telescopic groove 403.

[0031] It is worth noting that by setting the ejector spring 408, the locking block 404 can be continuously flexibly supported, so that the locking block 404 remains extended out of the telescopic groove 403.

[0032] A circular groove is provided on the top side of the locking block 404, and a ball bearing 405 is movably installed inside the circular groove. The ball bearing 405 abuts against the lower surface of the second flange 2.

[0033] This quick-detachable flange device, when connecting and installing the first flange 1 and the second flange 2, inserts the pin 401 from top to bottom into the flange hole 3, which keeps the locking nut 402 in place on the surface of the first thread section 4013. Then, the locking block 404 is pulled out from inside the telescopic groove 403, and the locking nut 402 is continued to be screwed. The locking nut 402 abuts against the upper surface of the first flange 1, and the ball bearing 405 and the locking block 404 abut against the lower surface of the second flange 2, thereby achieving the purpose of connecting and installing the two flanges.

[0034] It is worth noting that when it is necessary to disassemble the two flanges, the rolling friction effect of the ball bearing 405 is used to quickly push the locking block 404 into the telescopic groove 403, so that the pin 401 can be quickly removed from the flange hole 3, completing the flange disassembly. The entire disassembly and installation process does not require the locking nut 402 to be completely separated from the pin 401, reducing the number of turns and time required to rotate the locking nut 402, thereby improving the convenience of installation and disassembly.

[0035] The bottom end of the locking block 404 away from the pin 401 has a guide slope 406. When the pin 401 is inserted into the flange hole 3, the guide slope 406 slides in contact with the inner wall of the flange hole 3.

[0036] It is worth noting that by setting the guide slope 406 and utilizing the sliding contact between the guide slope 406 and the inner wall of the flange hole 3, the pin 401 can be quickly inserted into the flange hole 3.

[0037] The pin 401 has a second threaded section 409 on its surface near the bottom. The surface of the second threaded section 409 is threaded with a release ring 4010. The top of the release ring 4010 is slidably connected to the guide slope 406. The outer diameter of the release ring 4010 is smaller than the inner diameter of the flange hole 3.

[0038] The surface of the release ring 4010 is evenly provided with several anti-slip protrusions 4011 in a circular array.

[0039] It is worth noting that by setting the release ring 4010 and the anti-slip protrusion 4011, by rotating the release ring 4010 and utilizing the sliding between the release ring 4010 and the guide slope 406, the locking block 404 can be conveniently put into the telescopic groove 403, quickly and easily canceling the locking effect between the locking block 404 and the flange, and completing the disassembly action.

[0040] The upper side of the first threaded section 4013 is threaded with an anti-loosening nut 4012, which abuts against the upper side of the locking nut 402.

[0041] It is worth noting that by setting the anti-loosening nut 4012, the locking effect of the locking nut 402 can be improved, preventing the locking nut 402 from loosening during use.

[0042] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
