[0019] Figure 3 This is a schematic diagram of the structure of Example 2. DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be clearly and completely described below through specific implementation methods. Example 1

[0021] refer to Figure 1-Figure 2, is a construction engineering water supply and drainage anti-seepage device of the utility model, comprising a pipe joint 1 and a pipe joint 2, the pipe joint 1 and the pipe joint 2 are connected by threads, a pressure ring 3 is arranged on the outside of the pipe joint 1; a protective sleeve 4 is arranged on the outside of the pipe joint 2; an anti-seepage component 1 5 is arranged between the pipe joint 1 and the pipe joint 2; an anti-seepage component 2 6 and an anti-seepage component 3 7 are also arranged between the protective sleeve 4 and the pressure ring 3.

[0022] The pressure ring in this embodiment is provided with an upper clamping ring 31; the inner side of the protective sleeve 4 is provided with a lower clamping ring 32 matching the upper clamping ring; one side of the lower clamping ring is provided with an anti-seepage component 2 6 and the other side is provided with an anti-seepage component 3 7.

[0023] In this embodiment, three groups of different anti-seepage components are provided to improve the sealing effect of the pipeline connection and greatly reduce leakage.

[0024] The anti-seepage component 1 5 in this embodiment is a sealing ring 1 arranged on the inner side of the pipe joint 2 2 .

[0025] The anti-seepage component 2 6 of this embodiment includes a fixed sealing ring 61 arranged on the inner side of the protective sleeve 4 and a movable sealing ring 62 arranged on the upper side of the pressure ring 3; the movable sealing ring 62 is fixedly installed on a rotating ring 63, and the rotating ring 63 is slidably connected to the pressure ring 3.

[0026] When the pipe joint 1 and the pipe joint 2 2 in this embodiment are rotated and connected, the fixed sealing ring 61 and the movable sealing ring 62 of the anti-seepage component 2 6 are in contact first. After the two sealing rings are in contact, the friction force is too large, which affects the smooth rotation. At the same time, to avoid the wear of the sealing ring, the movable sealing ring 62 is fixed to the rotating ring 63, and the movable sealing ring 62 can rotate to avoid the wear of the sealing ring.

[0027] In this embodiment, the side walls of the fixed sealing ring 61 and the movable sealing ring 62 are V-shaped structures.

[0028] The V-shaped side wall structure allows the movable sealing ring 62 and the fixed sealing ring 61 to have a certain amount of expansion and contraction. When the pipe joint 1 and the pipe joint 2 continue to rotate, the movable sealing ring 62 and the fixed sealing ring 61 squeeze each other to improve the sealing effect.

[0029] In this embodiment, the anti-seepage component three 7 includes a sealing ring three arranged on the inner side of the protective sleeve 4; the inner wall, outer wall, bottom side wall and top side wall of the sealing ring three; two adjacent side walls are connected by an inclined connecting block; the side wall, outer wall, bottom side wall and top side wall are connected to form a hollow sealing ring; a pressure block for pressing against the sealing ring three is arranged on the outside of the pressure ring 3.

[0030] In this embodiment, an upper clamping ring 31 and a lower clamping ring 32 are provided to divide the cavity formed by the clamping ring and the protective sleeve 4 into cavity one and cavity two. After tightening, the upper clamping ring 31 and the lower clamping ring 32 are in close contact. The anti-seepage component three is used to seal the connection between the upper clamping ring 31 and the lower clamping ring 32 to form a third anti-seepage component.

[0031] The fixed sealing ring 61 and the movable sealing ring 62 of the anti-seepage component 2 are in contact first, and the installation process continues. The pressure block of the pressure ring 3 presses against the sealing ring 3, the sealing ring 3 is deformed, and the side wall is close to the connection seam between the upper clamping ring 31 and the lower clamping ring 32 to seal the connection seam. Example 2

[0032] like Figure 3 As shown, in this embodiment, the side wall of the protective sleeve 4 is also evenly provided with a plurality of fixing pins 81; the protective sleeve 4 is provided with a through hole 82 for the fixing pin 81 to pass through; the pressure ring is provided with a positioning hole 83 matching the fixing pin 81; the outer end of the fixing pin 81 is provided with a baffle 84; the fixing pin 81 is sleeved with a return spring 85, and the return spring 85 is located between the baffle 84 and the pressure ring; the inner wall of the through hole 82 is provided with a limited sliding groove, and the fixing pin 81 is provided with a limited sliding block matching the limited sliding groove. The pressure block is rotatably connected to the pressure ring, and a positioning groove is provided on the outer side of the pressure block, and a positioning convex ridge matching the positioning groove is provided on the inner side of the protective sleeve.

[0033] Preferably, one end of the return spring 85 is fixed to the outside of the pressure ring, and the other end is fixed to the sliding sleeve; the sliding sleeve is rotatably connected to the outer end of the fixing pin 81, an internal thread is provided in the positioning hole, and an external thread is provided at one end of the fixing pin 81.

[0034] In this embodiment, the fixing pin is provided to prevent the pipe joint 1 and the pipe joint 2 2 from moving relative to each other after the connection is fixed, resulting in poor sealing effect, thereby improving the firmness of the connection.

[0035] After the fixing pin falls into the positioning hole, it is rotated in a positioning manner and screwed with the pressing block to improve the firmness of the pipe joint connection.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
