[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1 A road water supply and drainage pipeline connection auxiliary device in this embodiment includes two drainage pipe bodies 1. The outer surfaces of the interfaces of the two drainage pipe bodies 1 on opposite sides are sleeved with sealing rings 2. The outer surfaces of the two drainage pipe bodies 1 are provided with mounting frames 3. The upper surface of the mounting frame 3 is provided with a fixing mechanism 4 for facilitating the staff to fix the sealing ring 2. The left and right ends of the outer surface of the mounting frame 3 are provided with reinforcing mechanisms 5 for strengthening the connection stability of the two drainage pipe bodies 1.

[0032] In this embodiment, the cross-sectional shape of the mounting frame 3 is an inverted U shape.

[0033] It should be noted that the sealing ring 2 is made of a rubber ring.

[0034] See also Figure 2 In order to clamp and fix the sealing ring 2, the fixing mechanism 4 in this embodiment includes a driving member 41, two clamping plates 42 and a limiting member 43. The driving member 41 is arranged on the upper surface of the mounting frame 3 and is used to drive the movement of the two clamping plates 42. The two clamping plates 42 are arranged in the inner cavity of the mounting frame 3. The limiting member 43 is arranged in the inner cavity of the mounting frame 3 and is used to limit the movement of the clamping plates 42.

[0035] The driving member 41 includes a first threaded rod 411, a screw sleeve 412, two movable plates 413, two fixed rods 414 and two mounting plates 415. The lower end of the first threaded rod 411 penetrates the mounting frame 3 and extends to the inner cavity of the mounting frame 3 and is rotatably connected to the upper surface of the sealing ring 2 through a bearing. The first threaded rod 411 is threadedly connected to the screw sleeve 412. The sealing ring 2 is sleeved on the outer surface of the interface of the two drainage pipe bodies 1 to rotate the first threaded rod 411. The rotation of the first threaded rod 411 drives the screw sleeve 412 to move downward. The two movable plates 413 are respectively fixed to the screw sleeves. On the left and right sides of 412, two fixing rods 414 are respectively fixed on the lower surfaces of the two movable plates 413 and are located on the side close to the mounting frame 3. The movement of the screw sleeve 412 drives the two movable plates 413 to move downward, thereby causing the two fixing rods 414 to move downward. The opposite sides of the two mounting plates 415 are fixed to the clamping plate 42. The movement of the fixing rods 414 can squeeze the mounting plate 415, thereby causing the mounting plate 415 to move toward the side close to the clamping plate 42. The movement of the two mounting plates 415 can drive the two clamping plates 42 to move relative to each other, thereby clamping and fixing the sealing ring 2.

[0036] In this embodiment, a handle is fixed on the upper surface of the first threaded rod 411, the cross-sectional shape of the mounting plate 415 is trapezoidal, and sliding grooves are provided on the opposite sides of the left and right side walls of the inner cavity of the mounting frame 3. Sliders are fixed on the opposite sides of the two movable plates 413 and the two fixed rods 414, and the sliders make linear up and down motions in the inner cavity of the sliding grooves. When the movable plate 413 and the fixed rods 414 move downward, the slider fixed on one side thereof slides in the inner cavity of the sliding grooves, thereby limiting the movement of the movable plate 413 and the fixed rods 414.

[0037] Among them, the limiting member 43 includes a connecting rod 431, two fixed sleeves 432 and four sliding sleeves 433, two fixed frames 434 and four moving rods 435, the two ends of the connecting rod 431 are respectively fixed between the side opposite to the bottom of the inner cavity of the mounting frame 3, the fixed sleeve 432 is fixed to the outer surface of the mounting plate 415, one end of the two fixed frames 434 is fixed to the inner top wall of the mounting frame 3, and the other end thereof is fixed to the side opposite to the left and right side walls of the inner cavity of the mounting frame 3, wherein the two sliding sleeves 433 are slidably connected to the left and right ends of the outer surface of the connecting rod 431, and the other two sliding sleeves 433 are respectively slidably connected to the outer surfaces of the two fixed frames 434, and the two ends of the moving rod 435 are respectively fixedly connected to the side opposite to the sliding sleeve 433 and the fixed sleeve 432.

[0038] It can be understood that when the mounting plate 415 moves, the fixed sleeve 432 fixed on its surface drives the moving rods 435 on the upper and lower sides to move, thereby causing the sliding sleeves 433 on the upper and lower sides to slide on the outer surfaces of the fixing frame 434 and the connecting rod 431 respectively, thereby limiting the movement of the mounting plate 415.

[0039] In this embodiment, a sliding hole is opened on the upper surface of the movable plate 413, and the two upper moving rods 435 perform horizontal linear motion in the inner cavity of the sliding hole. The cross-section shape of the fixing frame 434 is L-shaped.

[0040] See also Figure 3-4 In order to improve the stability of the connection between the two drain pipe bodies 1, the reinforcement mechanism 5 in this embodiment includes two fixing rings 51, four L-shaped frames 52 and four second threaded rods 53. The two fixing rings 51 are respectively fixed on the outer surfaces of the two drain pipe bodies 1, one end of the L-shaped frame 52 is fixed to the outer surface of the fixing ring 51, and the other ends of the four L-shaped frames 52 extend to the left and right sides of the mounting frame 3 respectively.

[0041] In this embodiment, two threaded grooves are provided on the left and right sides of the mounting frame 3. One end of the second threaded rod 53 passes through the L-shaped frame 52 and extends to the inner cavity of the threaded groove. The two fixing rings 51 on the outer surfaces of the two drainage pipe bodies 1 can be aligned with the threaded grooves, and then the second threaded rod 53 can be twisted to screw into the threaded grooves provided on the surface of the mounting frame 3, and the other second threaded rods 53 can be screwed in in turn to fix the fixing ring 51 to the mounting frame 3.

[0042] The working principle of the above embodiment is:

[0043] (1) When connecting two drainage pipe bodies 1, first, put the sealing ring 2 on the outer surface of the interface of the two drainage pipe bodies 1, and then turn the handle to rotate the first threaded rod 411. The rotation of the first threaded rod 411 drives the screw sleeve 412 to move downward. The movement of the screw sleeve 412 drives the two movable plates 413 to move downward, and then the two fixed rods 414 move downward. When the movable plate 413 and the fixed rod 414 move downward, the slider fixed on one side thereof slides in the inner cavity of the slide groove, which can control the movement of the movable plate 413 and the fixed rod 414. The movement of the fixing rod 414 can squeeze the mounting plate 415, thereby causing the mounting plate 415 to move toward the side close to the clamping plate 42. When the mounting plate 415 moves, the fixing sleeve 432 fixed on its surface drives the moving rods 435 on the upper and lower sides to move, thereby causing the sliding sleeves 433 on the upper and lower sides to slide on the outer surfaces of the fixing frame 434 and the connecting rod 431 respectively, thereby limiting the movement of the mounting plate 415. The movement of the two mounting plates 415 can drive the two clamping plates 42 to move relative to each other, thereby clamping and fixing the sealing ring 2.

[0044] (2) In order to improve the stability of the connection between the two drain pipe bodies 1, the two fixing rings 51 on the outer surfaces of the two drain pipe bodies 1 can be aligned with the threaded groove, and then the second threaded rod 53 can be twisted to screw it into the threaded groove opened on the surface of the mounting frame 3, and the other second threaded rods 53 can be screwed in in turn to fix the fixing ring 51 to the mounting frame 3.
