[0028] Example 1

[0029] Reference Figures 1-7 This is the first embodiment of the present utility model. This embodiment provides an easy-to-clean elbow fitting, which includes a main body component 100 and an elbow 101.

[0030] Cleaning assembly 200, disposed within the bend 101, includes a cleaning component 201. The cleaning component 201 includes a guide rail 201a, a sleeve 201b, a locking block 201c, a moving ring 201d, a fixing ring 201e, a first connecting rod 201f, a second connecting rod 201g, and a cleaning plate 201h. The guide rail 201a is disposed within the bend 101, and the sleeve 201b is fitted over the guide rail 201a. A spiral groove 2 is formed on the guide rail 201a. 01a-1, the locking block 201c slides in the spiral groove 201a-1, one end of the locking block 201c is fixed on the sleeve 201b, the moving ring 201d is sleeved on the sleeve 201b, the fixed ring 201e is fixed to one end of the sleeve 201b, one end of the first connecting rod 201f is hinged to the moving ring 201d, one end of the second connecting rod 201g is hinged to the fixed ring 201e, and the other end of the first connecting rod 201f and the second connecting rod 201g are hinged.

[0031] The cleaning component 201 is designed to clean the inner wall of the bend 101, thereby ensuring the pipeline's transport efficiency.

[0032] The sleeve 201b can be bent to adapt to the bent part of the bend 101. The inner rings of the moving ring 201d and the fixed ring 201e have a certain deformation capacity to ensure that when the sleeve 201b moves along the guide rail 201a to the bent part, the sleeve 201b bends accordingly. At this time, the internal deformation of the moving ring 201d and the fixed ring 201e will not hinder the bending of the sleeve 201b.

[0033] There are four cleaning plates 201h. Through the cooperation of the moving ring 201d, the fixed ring 201e, the first connecting rod 201f, the second connecting rod 201g and the cleaning plates 201h, when the moving ring 201d approaches the fixed ring 201e, one end of the first connecting rod 201f will simultaneously approach the fixed ring 201e, thereby causing the other end of the first connecting rod 201f to move upward, which in turn drives the cleaning plates 201h to move away from the sleeve 201b. The movement of the moving ring 201d simultaneously drives the four cleaning plates 201h to move synchronously, ultimately causing the cleaning plates 201h to expand outward and fit against the inner wall of the bend 101.

[0034] When the sleeve 201b moves along the guide rail 201a, the locking block 201c slides in the spiral groove 201a-1. Through the cooperation of the two, the sleeve 201b rotates around the guide rail 201a, thereby driving the cleaning plate 201h to rotate and move along the inner wall of the bend 101, thereby cleaning the impurities accumulated on the inner wall and ensuring the conveying efficiency of the bend 101.

[0035] Example 2

[0036] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the cleaning component 200 also includes an auxiliary component 202 located on one side of the sleeve 201b, including a fixed post 202a, an auxiliary ring 202b, a rotating block 202c, and a first pull rope 202d. The fixed post 202a is fixed on the moving ring 201d, the auxiliary ring 202b is located on one side of the fixed ring 201e, and a first annular groove 202b-1 is provided in the auxiliary ring 202b. The rotating block 202c slides in the first annular groove 202b-1. The rotating block 202c is fixed to one end of the fixed post 202a, and one end of the first pull rope 202d is fixed to the auxiliary ring 202b.

[0038] The auxiliary component 202 is designed to drive the moving ring 201d and the sleeve 201b to move.

[0039] There are two fixed posts 202a, symmetrically distributed on the moving ring 201d. The fixed posts 202a have a certain deformation capacity and can be bent to support and position the auxiliary ring 202b. The fixed ring 201e has through holes corresponding to the fixed posts 202a. The fixed posts 202a pass through the fixed ring 201e. The rotating block 202c is used to connect the fixed posts 202a and the auxiliary ring 202b. The rotating block 202c has a T-shaped cross section to ensure that the rotating block 202c can slide in the first annular groove 202b-1 and will not separate from it.

[0040] The other end of the first pull rope 202d extends to the outside of the bend 101. The bend 101 has a hole corresponding to the first pull rope 202d, and a sealing sleeve 202h is installed in the hole to ensure the sealing of the bend 101.

[0041] When the first pull rope 202d is pulled to move and rotate the sleeve 201b along the guide rail 201a, the moving ring 201d and the fixed ring 201e will rotate synchronously. At this time, the rotating block 202c will slide in the first annular groove 202b-1, and the first pull rope 202d will not be entangled with the guide rail 201a.

[0042] Pulling the first pull rope 202d will move the auxiliary ring 202b, causing the moving ring 201d to move closer to the fixed ring 201e. This will cause the cleaning plate 201h to expand outward and fit against the inner wall of the bend 101. When the moving ring 201d contacts the fixed ring 201e, the moving ring 201d will no longer move, thereby causing the sleeve 201b to move and rotate along the guide rail 201a. At this time, the cleaning plate 201h rotates and moves along the inner wall of the bend 101, thereby cleaning the impurities accumulated on the inner wall.

[0043] Specifically, the cleaning component 200 also includes a locking element 203, which is disposed in the sleeve 201b and includes a locking block 203a and a contact ring 203b. A first moving groove 201b-1 is provided in the sleeve 201b, and the locking block 203a slides in the first moving groove 201b-1. A second annular groove 201b-2 is provided in the sleeve 201b, and the contact ring 203b can slide in the second annular groove 201b-2. A force-receiving groove 203a-1 is provided on the locking block 203a, and one end of the contact ring 203b can engage with the force-receiving groove 203a-1.

[0044] By setting the locking element 203, the positions of the moving ring 201d and the sleeve 201b are locked. In the initial state, the force groove 203a-1 is engaged with the contact ring 203b. At this time, the bottom of the locking block 203a is located in the spiral groove 201a-1. Through the cooperation of the contact ring 203b and the locking block 203a, the sleeve 201b cannot move along the guide rail 201a, thereby locking the sleeve 201b and preventing the sleeve 201b from moving when cleaning is not required.

[0045] The force-receiving groove 203a-1 is inclined, and one end of the contact ring 203b is also inclined. When the contact ring 203b contacts the force-receiving groove 203a-1, the contact ring 203b will apply a pushing force to the force-receiving groove 203a-1, thereby causing the locking block 203a to move downward along the first moving groove 201b-1 into the spiral groove 201a-1.

[0046] Specifically, a support block 203c is fixed to one side of the locking block 203a, and a spring 203d is fixed to the other end of the support block 203c.

[0047] In the initial state, the spring 203d is in an extended state. When the first pull rope 202d is pulled, causing the sleeve 201b to move along the guide rail 201a, the contact ring 203b no longer presses against the force groove 203a-1, and the spring 203d will contract, causing the locking block 203a to move upward, so that the upper end face of the locking block 203a protrudes from the first moving groove 201b-1. At this time, the moving ring 201d is located between the locking block 203a and the fixed ring 201e. The locking block 203a will prevent the moving ring 201d from separating from the fixed ring 201e, thereby ensuring the expanded state of the cleaning plate 201h and ensuring that the cleaning plate 201h is always in contact with the inner wall of the bend 101.

[0048] Specifically, the locking block 203a is cylindrical, and the bottom end of the locking block 203a can be located in the spiral groove 201a-1.

[0049] Specifically, an annular block 202e is fixed on one side of the moving ring 201d. A third annular groove 202e-1 is opened in the annular block 202e. A slider 202f is set in the third annular groove 202e-1. A second pull rope 202g is fixed on the slider 202f.

[0050] The other end of the second pull rope 202g is connected to the outside of the bend 101. The bend 101 has a hole corresponding to the second pull rope 202g, and a sealing sleeve 202h is installed in the hole to ensure the sealing of the bend 101.

[0051] One end of the second pull rope 202g is fixed with a pull ring, and a hook is fixed to the outside of the bend 101. When cleaning is not required, the pull ring is connected to the hook to fix the end of the second pull rope 202g, thereby preventing the moving ring 201d from moving. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0052] When the sleeve 201b moves and rotates along the guide rail 201a and drives the moving ring 201d to rotate synchronously with the fixed ring 201e, the moving ring 201d drives the annular block 202e to rotate. Since the slider 202f can slide in the third annular groove 202e-1, the rotation of the annular block 202e can prevent the second pull rope 202g from getting tangled.

[0053] Pulling the second rope 202g will cause the sleeve 201b to return to its initial position.

[0054] Example 3

[0055] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0056] Specifically, the cleaning plate 201h is fixed with bristles 201i.

[0057] There are multiple bristles 201i. The cleaning plate 201h rotates, causing the bristles 201i to move along the inner wall of the curved tube 101, thus cleaning the inner wall without dead angles.

[0058] Specifically, the guide rail 201a is divided into three sections: the first straight section 201a-2, the curved section 201a-3, and the second straight section 201a-4.

[0059] In the initial state, the sleeve 201b is located on the first straight segment 201a-2. Pulling the first pull rope 202d can move the sleeve 201b from the first straight segment 201a-2 through the curved segment 201a-3 to the second straight segment 201a-4. Pulling the second pull rope 202g can drive the sleeve 201b to move in the opposite direction.

[0060] Specifically, the guide rail 201a has support plates 201j fixed at both ends, and the support plates 201j are fixed to the inner wall of the bend 101.

[0061] There are two support plates 201j, which support and position the guide rail 201a.

[0062] Specifically, one end of the contact ring 203b is fixed to the support plate 201j.

[0063] After one cleaning cycle, the sleeve 201b returns to its initial position. At this time, the contact ring 203b will engage with the force groove 203a-1 again, causing the spring 203d to extend. The bottom end of the locking block 203a will once again be located in the spiral groove 201a-1, thereby locking the position of the sleeve 201b.

[0064] In use, in the initial state, the sleeve 201b is located on the first straight segment 201a-2, the force groove 203a-1 is engaged with the contact ring 203b, and at this time the bottom of the locking block 203a is located in the spiral groove 201a-1, and the position of the sleeve 201b is locked.

[0065] When cleaning is required, first separate the end of the second pull rope 202g from the hook, then pull the first pull rope 202d. This will move the auxiliary ring 202b, which in turn moves the moving ring 201d, causing it to move closer to the fixed ring 201e. Simultaneously, one end of the first connecting rod 201f will move closer to the fixed ring 201e, causing the other end of the first connecting rod 201f to move upwards. This, in turn, moves the cleaning plate 201h away from the sleeve 201b. The movement of the moving ring 201d simultaneously moves all four cleaning plates 201h. The cleaning plate 201h expands outward as the bristles 201i come into contact with the inner wall of the bend 101. When the moving ring 201d contacts the fixed ring 201e, the moving ring 201d stops moving and drives the sleeve 201b to move along the guide rail 201a. At this time, the locking block 201c slides in the spiral groove 201a-1, causing the sleeve 201b to rotate around the guide rail 201a. This causes the cleaning plate 201h to move and rotate along the inner wall of the bend 101, thereby cleaning the impurities accumulated on the inner wall and ensuring the conveying efficiency of the bend 101.

[0066] When the first pull rope 202d is pulled, causing the sleeve 201b to move along the guide rail 201a, the contact ring 203b no longer presses against the force groove 203a-1, and the spring 203d will contract, causing the locking block 203a to move upward, so that the upper end face of the locking block 203a protrudes out of the first moving groove 201b-1. At this time, the moving ring 201d is located between the locking block 203a and the fixed ring 201e, and the locking block 203a will prevent the moving ring 201d from separating from the fixed ring 201e.

[0067] When the sleeve 201b moves to the end of the second straight segment 201a-4, pulling the second pull rope 202g will cause the slider 202f, the annular block 202e, and the moving ring 201d to move in the opposite direction. Since the locking block 203a will prevent the moving ring 201d from separating from the fixed ring 201e, the cleaning plate 201h will remain in an expanded state, ensuring that the cleaning plate 201h is always in contact with the inner wall of the bend 101. As the second pull rope 202g is pulled, the sleeve 201b will move in the opposite direction to the initial position, causing the bristles to... 201i performs cleaning again. When the sleeve 201b returns to its initial position, the contact ring 203b will engage with the force groove 203a-1 again and compress the force groove 203a-1, thereby extending the spring 203d. The bottom end of the locking block 203a is once again located in the spiral groove 201a-1, thus locking the position of the sleeve 201b. At this time, the locking block 203a no longer obstructs the movement of the moving ring 201d, thereby causing the moving ring 201d to move away from the fixed ring 201e, thereby causing the cleaning plate 201h to retract.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
