Abstract

This utility model relates to a locking type pipe connection flange in the field of pipe connection technology. When connecting the first and second pipes, the fixing ring is moved towards the slot cavity, causing the slider to slide within the positioning groove. The guide groove moves closer to the through groove. By gripping the ring handle and rotating the locking cover, the internal thread engages with the external thread, causing the locking cover to move to the left. The arc-shaped edge pushes the triangular latch, causing it to gradually move from the first slot cavity to the second slot cavity. Simultaneously, the triangular latch engages in the guide groove. The outer wall of the triangular latch pushes the inclined edge of the guide groove, causing the connecting pipe and the inner wall of the slot cavity to press tightly together, thus completing the connection of the first and second pipes. Therefore, this utility model provides a simple connection operation for the first and second pipes; simply rotating the locking cover is sufficient to lock and unlock multiple triangular latches on the first pipe.

Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a locking type pipe connection flange. Background Technology

[0002] A pipe flange is a component used to connect pipes. It is usually made of a disc-shaped metal sheet with multiple holes for bolts and nuts to fit together two pipes.

[0003] For example, Chinese patent application CN202322410434.6 discloses a flange for chemical pipelines, which specifically includes a first flange and a second flange. A first pipe is provided at the end of the first flange away from the second flange, and a second pipe is provided at the end of the second flange away from the first flange. First bolt mounting holes are evenly distributed on the outer periphery of the side of the first flange, and second bolt mounting holes are evenly distributed on the outer periphery of the side of the second flange. However, it also has the following technical problems:

[0004] The above structure uses multiple bolts to fix the two flanges, and in actual operation, the operation of tightening the bolts is quite cumbersome. Utility Model Content

[0005] To address the cumbersome bolt tightening operation mentioned in the background section, this utility model provides the following technical solution:

[0006] A locking pipe connection flange includes a locking cap for easy locking of a first pipe and a second pipe;

[0007] A connecting pipe 2 is installed at one end of the second pipe. The outer wall of the connecting pipe 2 has multiple through grooves, and a triangular lock is installed in the through grooves for locking the first pipe.

[0008] One end of the locking cover is equipped with a magnetic ring for controlling the reset of the triangular lock, and the inside of the locking cover is machined with an arc-shaped edge to facilitate pushing the triangular lock.

[0009] Furthermore, a fixing ring is installed at the right end of the first pipe, and a connecting pipe is installed at the right end of the fixing ring. The outer wall of the connecting pipe is provided with multiple positioning grooves, and the outer wall of the connecting pipe is provided with multiple guide grooves for cooperating with the triangular lock to control the connecting pipe to be tightly close to the connecting pipe.

[0010] Furthermore, the outer right side of the second connecting pipe is machined with external threads, and a limiting shaft for limiting the triangular lock is installed inside the through groove. The left side of the second connecting pipe is provided with a slot for the first connecting pipe to be inserted. Multiple sliders for positioning the guide groove in conjunction with the positioning groove are installed on the left side of the slot cavity.

[0011] Furthermore, one end of the triangular latch is fitted with a magnetic block that is magnetically attracted to the magnetic ring.

[0012] Furthermore, a plurality of connecting rods are installed on the right outer wall of the locking cover, and a ring handle for rotating the locking cover is installed on one side of each connecting rod.

[0013] Furthermore, the locking cover has a first groove and a second groove on its left side, and the diameter of the first groove is larger than the diameter of the second groove.

[0014] Furthermore, the right side of the second cavity is machined with an internal thread for cooperating with the external thread to control the locking cover to move to the left.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When connecting the first and second pipes, the fixing ring is moved towards the slot cavity, causing the slider to slide within the positioning groove. The guide groove moves closer to the through groove. By holding the ring handle and rotating the locking cover, the internal thread engages with the external thread, causing the locking cover to move to the left. The arc-shaped edge pushes the triangular latch, causing it to gradually move from the first slot cavity to the second slot cavity. The triangular latch simultaneously engages in the guide groove, and the outer wall of the triangular latch pushes the inclined edge of the guide groove, causing the connecting pipe and the inner wall of the slot cavity to press tightly together, thus completing the connection of the first and second pipes. It can be seen that the connection operation of the first and second pipes in this utility model is relatively simple. Only by rotating the locking cover can the locking and unlocking of multiple triangular latches on the first pipe be completed. Attached Figure Description

Detailed Implementation

[0023] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0024] Please see Figures 1-4 This utility model provides a locking type pipe connection flange, including a locking cover 300 for easy locking of a first pipe 100 and a second pipe 200. A connecting pipe 210 is fixedly installed at the left end of the second pipe 200. The outer wall of the connecting pipe 210 has multiple through grooves 212. A triangular lock 220 for locking the first pipe 100 is movably installed in the through grooves 212. By pushing the first pipe 100 with the triangular lock 220, the first pipe 100 and the connecting pipe 210 are pressed together. The continuous pushing of the first pipe 100 by the triangular lock 220 enables a good sealing effect between the first pipe 100 and the second pipe 200.

[0025] A fixing ring 110 is fixedly installed at the right end of the first pipe 100. A connecting pipe 111 is installed at the right end of the fixing ring 110. Multiple positioning grooves 112 are opened on the outer wall of the connecting pipe 111. Multiple guide grooves 113 are opened on the outer wall of the connecting pipe 111 to cooperate with the triangular lock 220 to control the connecting pipe 111 to be close to the connecting pipe 210. The cross section of the guide groove 113 is a right trapezoid, and the hypotenuse of the guide groove 113 faces the direction of the second pipe 200.

[0026] The through groove 212 is equipped with a limiting shaft 213 for limiting the triangular latch 220. The left side of the connecting pipe 210 is provided with a slot 214 for the connecting pipe 111 to be inserted. After the connecting pipe 111 is inserted into the slot 214, the locking cover 300 controls the multiple triangular latches 220 to flip, so that the triangular latches 220 are inserted into the guide groove 113 and push the inclined side of the guide groove 113, pushing the connecting pipe 111 into the depth of the slot 214 until the connecting pipe 111 and the inner wall of the slot 214 are pressed together. The slot 214 can be equipped with a sealing gasket of the prior art to prevent leakage of the medium flowing in the first pipe 100 and the second pipe 200.

[0027] Multiple sliders 215 are fixedly installed on the left side of the slot cavity of slot 214 to position the guide groove 113 in conjunction with the positioning groove 112. When the first pipe 100 and the second pipe 200 are assembled, the sliders 215 are inserted into the positioning groove 112, and the connecting pipe 111 can be inserted into the slot 214. When the sliders 215 slide in the positioning groove 112, the guide groove 113 gradually moves closer to the triangular lock 220 so that when the triangular lock 220 is flipped, it can be locked into the guide groove 113 and abut against the inclined side of the guide groove 113.

[0028] Multiple connecting rods 301 are fixedly installed on the right outer wall of the locking cover 300. A ring handle 302 for rotating the locking cover 300 is installed on one side of each connecting rod 301. The left side of the locking cover 300 has a first cavity 303 and a second cavity 304, and the diameter of the first cavity 303 is larger than the diameter of the second cavity 304. The interior of the locking cover 300 is machined with an arc-shaped edge 305 to facilitate pushing the triangular lock 220. The arc-shaped edge 305 is located between the first cavity 303 and the second cavity 304 so that the arc-shaped edge 305 abuts against the outer wall of the triangular lock 220, thereby pushing the triangular lock 220 so that the triangular lock 220 engages in the guide groove 113, thus locking the connecting tube 111.

[0029] A magnetic ring 307 for controlling the reset of the triangular latch 220 is installed at one end of the locking cover 300. A magnetic block 221 that is magnetically attracted to the magnetic ring 307 is installed inside one end of the triangular latch 220. When the magnetic ring 307 rotates to the side of the magnetic block 221, the end of the triangular latch 220 with the magnetic block 221 can be drawn into the first groove 303, so that the triangular latch 220 is away from the groove of the guide groove 113, thereby allowing the first pipe 100 to be quickly disassembled. The right side of the second groove 304 is machined with an internal thread 306 for cooperating with the external thread 211 to control the locking cover 300 to move to the left. The right outer wall of the connecting pipe 210 is machined with an external thread 211, and the external thread 211 and the internal thread 306 are threadedly connected.

[0030] When connecting the first pipe 100 and the second pipe 200, the fixing ring 110 is moved into the cavity of the slot 214, causing the slider 215 to slide in the positioning groove 112. The guide groove 113 moves closer to the through groove 212. By holding the ring handle 302, the locking cover 300 is rotated, causing the internal thread 306 to engage with the external thread 211, which moves the locking cover 300 to the left. The arc edge 305 pushes the triangular lock 220, causing the triangular lock 220 to gradually move from the cavity of the first cavity 303 to the cavity of the second cavity 304. The triangular lock 220 is simultaneously engaged in the guide groove 113. The outer wall of the triangular lock 220 pushes the inclined side of the guide groove 113, causing the connecting pipe 111 and the inner wall of the cavity of the slot 214 to press tightly together, thereby completing the connection of the first pipe 100 and the second pipe 200. When the locking of the first pipe 100 and the second pipe 200 is released, the locking cover 300 is rotated in the opposite direction. When the locking cover 300 is moved away from the first pipe 100, the magnetic ring 307 magnetically attracts the magnetic block 221, thereby driving the triangular lock buckle 220 to disengage from the guide groove 113, so that the fixing ring 110 can be removed.

[0031] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
