Description

Technical Field

[0001] The utility model relates to the technical field of flange connectors, in particular to a variable diameter flange connector. Background Art

[0002] Flange connectors can also be called pipe connectors. They can be used to connect two pipes of different materials or outer diameters. They are easy to install and construct.

[0003] The utility model patent application document with announcement number "CN217463637U" discloses a quick-type pipe connector, which is mainly composed of a connector body, a fixing seat, a fixing bolt, an extrusion plate, a guide rod and a sealing gasket. The technical solution is to set a clamping assembly. Since the thread directions of the surfaces at both ends of the screw are opposite, rotating the screw can make the two transmission blocks drive the clamps to move toward each other respectively, and the clamps clamp and position the mechanical accessories to achieve higher grinding accuracy; the utility model places the convex edge of one end of the required connecting pipe between the fixing seat and the connector body, and rotates the fixing bolt to drive the extrusion plate to move, so that the convex edge of the required connecting pipe can be squeezed, and the required connecting pipe can be connected to the connector body. No flange and multiple bolts are used for fixing, so that connection and disassembly are very fast and convenient, and the filter net can filter the water passing through the inside of the connector body.

[0004] The pipe connector disclosed in the above document has the following defects: when the fixing seat of the pipe connector is damaged, the fixing seat cannot be replaced, which will cause waste of materials and poor environmental protection effect.

[0005] It can be seen from this that the fixing seat of the existing pipe connector cannot be replaced, and it is necessary to improve the existing shortcomings and provide a variable diameter flange connector. Utility Model Content

[0006] The purpose of the utility model is to provide a variable diameter flange connector to solve the problems raised in the above background technology.

[0009] Further, the fixing assembly includes a mounting block, a through hole is provided on the outer surface of the mounting block, a slide groove is provided on the inner surface of the through hole, a second guide rod is provided inside the slide groove, a slider is slidably connected to the outer surface of the second guide rod, the sliders are set to be two and symmetrically distributed, a first spring is provided between the two sliders, a limit block is provided on the outer surface of the slider, the limit block is slidably connected to the inside of the through hole, a through opening is provided on the inner surface of the mounting groove, a mounting block is cooperatively installed inside the through opening, and the outer surface of the limit block abuts against the outer surface of the second connecting plate.

[0010] Furthermore, an outer surface of the limit block is provided with an inclined surface.

[0011] Furthermore, an outer surface of the first guide rod is provided with an external thread, and the first guide rod is threadably connected to an anti-slip block via the external thread.

[0012] Furthermore, a second spring is sleeved on the outer surface of the first guide rod, one end of the second spring is mounted on the outer surface of the extrusion plate, and the other end of the second spring is mounted on the outer surface of the fixing seat.

[0013] Furthermore, the outer surfaces of the first connection disk and the second connection disk are both provided with sealing grooves, and sealing rings are installed in the sealing grooves.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model squeezes the limit blocks at both ends of the mounting block so that the limit blocks move into the through hole, and the slider moves synchronously in the slide groove. At the same time, the first spring gradually contracts. When the outer surface of the limit block is flush with the outer surface of the mounting block, the fixing seat can be pulled outward to disengage the mounting block from the through hole, thereby separating the fixing seat from the second connecting plate, completing the disassembly of the fixing seat, and then replacing the fixing seat, which has a better environmental protection effect and avoids waste of materials.

[0026] The connector body 1 is a reducing flange;

[0027] When using the reducer flange connector, place the convex change of the required connecting pipe in the gap between the connector body 1 and the fixing seat 2, turn the knob 5, so that the knob 5 drives the threaded section 4 to rotate, so that the threaded section 4 moves upward or downward along the axis with the threaded hole as the center. When the threaded section 4 moves downward, the threaded section 4 drives the extrusion plate 7 to move downward, and the extrusion plate 7 can squeeze the convex edge of the required connecting pipe until the required connecting pipe fits the outer wall of the connector body 1;

[0028] The outer surfaces of the first connection plate 101 and the second connection plate 102 are both provided with sealing grooves 106, and the sealing rings 11 are installed in the sealing grooves 106;

[0029] The sealing ring 11 can ensure the sealing between the required connecting pipe and the connector body 1;

[0030] The fixing assembly 3 includes a mounting block 301, a through hole 302 is formed on the outer surface of the mounting block 301, a slide groove 303 is formed on the inner surface of the through hole 302, a second guide rod 304 is formed inside the slide groove 303, a slider 305 is slidably connected to the outer surface of the second guide rod 304, two sliders 305 are set and symmetrically distributed, a first spring 306 is provided between the two sliders 305, a limit block 307 is formed on the outer surface of the slider 305, the limit block 307 is slidably connected to the inside of the through hole 302, a through opening 105 is formed on the inner surface of the mounting groove 104, the mounting block 301 is installed in cooperation with the through opening 105, and the outer surface of the limit block 307 abuts against the outer surface of the second connection plate 102;

[0031] The outer surface of the limit block 307 is provided with an inclined surface;

[0032] When the fixing seat 2 needs to be disassembled, the limiting blocks 307 at both ends of the mounting block 301 are squeezed to move the limiting blocks 307 into the through hole 302, and the slider 305 moves synchronously in the slide groove 303. At the same time, the first spring 306 gradually contracts. When the outer surface of the limiting block 307 is flush with the outer surface of the mounting block 301, the fixing seat 2 can be pulled outward to disengage the mounting block 301 from the through opening 105, thereby separating the fixing seat 2 from the second connecting plate 102, and the fixing seat 2 is disassembled.

[0033] When the fixing seat 2 needs to be installed, the mounting block 301 is aligned with the through opening 105, and then the fixing seat 2 is pushed downward, so that the mounting block 301 moves into the through opening 105. When the outer surface of the limit block 307 abuts against the inner surface of the through opening 105, since the outer surface of the limit block 307 is provided with an inclined surface, this will cause the limit block 307 to move into the through hole 302, and the slider 305 moves synchronously in the slide groove 303. At the same time, the first spring 306 gradually contracts. When the outer surface of the limit block 307 is flush with the outer surface of the mounting block 301, The fixing seat 2 can be pushed further to make the mounting block 301 slide in the through opening 105. When the fixing seat 2 is mounted in the mounting groove 104, the mounting block 301 is mounted in the through opening 105. At this time, the first spring 306 recovers its elasticity and pushes the slider 305 to reset, so that the limit block 307 extends outward in the through hole 302, so that the outer surface of the limit block 307 abuts against the outer surface of the second connection disk 102, and then the limit block 307 and the second connection disk 102 are fixedly mounted together, completing the installation of the fixing seat 2.
