[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an anti-slip hardware sleeve connection accessory, including a first pipe 1 and a second pipe 2, a connecting mechanism 3 is provided on one side surface of the second pipe 2, a fixing ring 4 is provided on one side surface of the connecting mechanism 3, and a sealing sleeve 5 is fixedly connected to the inner side of the fixing ring 4.

[0022] The connecting mechanism 3 includes a slotted self-tapping threaded sleeve 301, which is fixedly connected to the outer surface of the second pipe 2 by a nut. A disc 302 is fixedly connected to one side surface of the slotted self-tapping threaded sleeve 301. A movable groove 303, a retaining groove 304, a circular hole 305, and a fixing groove 306 are formed on one side surface of the disc 302. A connecting piece 307 is slidably connected to the inner surface of the movable groove 303. An annular part 309 is fixedly connected to one side surface of the connecting piece 307. A retaining block 310 is fixedly connected to one side surface of the connecting piece 307. A fixing ring 4 is inserted into the inner side of the fixing groove 306. A sealing ring 310 is fixedly connected to the inner side of the fixing ring 4. The sealing sleeve 5, through the arrangement of the slotted self-tapping threaded sleeve 301, disc 302, movable groove 303, slot 304, round hole 305, fixing groove 306, connecting piece 307, ring part 309 and locking block 310, is used to fix the first pipe 1 and the second pipe 2 to the disc 302 by nuts, the slotted self-tapping threaded sleeve 301 and the disc 302. Then, the two discs 302 are joined together. The ring part 309 is used to make the locking block 310 pass through the slot 304 and drive the connecting piece 307 to rotate along the movable groove 303, so that the locking block 310 moves away from the slot 304. At the same time, the connecting piece 307 is tightly attached to the outer wall surface of the disc 302 to complete the locking. Meanwhile, the fixing ring 4, through the insertion and cooperation with the fixing groove 306, forms a radial fixation for the sealing sleeve 5 inside the round hole 305. The mechanism has strong versatility.

[0023] Furthermore, an anti-slip strip 308 is fixedly connected to one side surface of the connecting piece 307. The connecting piece 307 has two pieces of the same size, and the anti-slip strip 308 has multiple pieces of the same size. With the anti-slip strip 308, when the operator rotates the connecting piece 307 to engage or disengage the locking block 310 and the locking groove 304, the anti-slip strip 308 can increase the friction between the hand and the connecting piece 307. Even if the hand is covered with oil or water or is in a relatively slippery environment, the operator can hold the connecting piece 307 stably and avoid slipping.

[0024] Furthermore, a washer 6 is fixedly connected to the outside of the slotted self-tapping threaded sleeve 301 by a nut. Two washer 6s of the same size are provided. The cross-section of the washer 6 is designed in the shape of "◎". With the setting of the washer 6, when the nut is tightened to fix the slotted self-tapping threaded sleeve 301 during use, the two "◎" shaped washer 6 will be tightly squeezed between the nut and the slotted self-tapping threaded sleeve 301, which further improves the sealing and fastening effect.

[0025] Further, there are two sets of clamping blocks 310 with the same size, and two clamping blocks 310 with the same size are arranged in each set. The size of the clamping blocks 310 is adapted to that of the clamping grooves 304. Through the arrangement of the clamping blocks 310 and the clamping grooves 304, in use, the clamping blocks 310 firstly pass through the corresponding clamping grooves 304, and after the connecting piece 307 rotates to a proper position, the clamping blocks 310 are staggered from the clamping grooves 304. At this time, the clamping blocks 310 closely abut against the outer wall of the disc 302, forming a mechanical locking structure with the clamping grooves 304, and locking and unlocking can be completed without complex tools.

[0026] Further, the size of the sealing sleeve 5 is adapted to that of the circular hole 305, and the sealing sleeve 5 is made of nitrile rubber. Through the arrangement of the sealing sleeve 5 and the circular hole 305, in use, the circular hole 305 can play a limiting role on the sealing sleeve 5, ensuring that the sealing sleeve 5 is not prone to shaking.

[0027] Further, there are two slotted self-tapping threaded sleeves 301 and two discs 302 with the same size, and the annular member 309, the discs 302, the slotted self-tapping threaded sleeves 301, the fixing ring 4 and the sealing sleeve 5 are located on the same horizontal line. Through the arrangement of the slotted self-tapping threaded sleeves 301, in use, the design of the slotted self-tapping threaded sleeves 301 can adapt to pipes with different pipe diameters within a certain range, and there is no need to additionally customize accessories for slight size differences. By means of the cooperation of the slotted self-tapping threaded sleeves 301 and nuts, a tight engagement with the surface of the pipe can be formed.

[0028] Further, the size of the fixing groove 306 is adapted to that of the fixing ring 4, and the disc 302 and the slotted self-tapping threaded sleeve 301 are arranged in a convex shape. Through the arrangement of the fixing groove 306 and the fixing ring 4, in use, after the two discs 302 are butted and fixed, the fixing ring 4 can be accurately embedded into the fixing groove 306. Since the sizes of the two are adapted, a tight clamping structure can be formed, which firmly limits the sealing sleeve 5 at a preset position, and prevents the sealing sleeve 5 from shifting, loosening or even falling off when the pipe vibrates, is impacted by medium or the temperature changes.

[0029] Working principle: When connecting the first pipe 1 and the second pipe 2, the connecting mechanism 3 achieves precise docking and fixation. The first pipe 1 and the second pipe 2 are fixed to the disc 302 by nuts and slotted self-tapping threaded sleeves 301. At the same time, the "◎"-shaped gasket 6 on the outside of the slotted self-tapping threaded sleeve 301 can reduce loosening caused by vibration. Then, the two discs 302 are docked. The ring part 309 is used to make the locking block 310 pass through the locking groove 304 and drive the connecting piece 307 to rotate along the movable groove 303, so that the locking block 310 moves away from the locking groove 304. At the same time, the connecting piece 307 is tightly attached to the outer wall surface of the disc 302 to complete the locking. Multiple anti-slip strips 308 on the surface of the connecting piece 307 facilitate rotation. Meanwhile, the fixing ring 4, through the insertion and cooperation with the fixing groove 306, forms a radial fixation for the sealing sleeve 5, preventing the sealing sleeve 5 from shifting and ensuring the durability of the sealing performance. This completes the use process of an anti-slip hardware sleeve connection accessory.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
