DETAILED DESCRIPTION

[0022] The following will be combined with 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 of 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.

[0023] Example 1

[0024] like Figure 1~Figure 5 As shown, this embodiment proposes a U-shaped elbow malleable cast iron pipe fitting, including a U-shaped elbow malleable cast iron pipe fitting body 1, a mounting mechanism 2 for convenient connection with a wall is installed in the middle of the U-shaped elbow malleable cast iron pipe fitting body 1, sleeves 3 are fixed on both sides of the U-shaped elbow malleable cast iron pipe fitting body 1, and a reinforcing rib 4 is fixed between the two sleeves 3. The side walls at both ends of the U-shaped elbow malleable cast iron pipe fitting body 1 are provided with mounting grooves 5 for inserting the pipe to be connected, and threaded sleeves 7 are screwed at both ends of the U-shaped elbow malleable cast iron pipe fitting body 1. Fixing mechanisms 6 are installed at the positions of the threaded sleeves 7 at both ends of the U-shaped elbow malleable cast iron pipe fitting body 1. A sealing ring 8 is fixed on the inner wall of the mounting groove 5. The outer wall of the threaded sleeve 7 is provided with anti-slip convex patterns.

[0025] In this embodiment, the provided installation mechanism 2 can facilitate the installation of the U-shaped elbow malleable cast iron pipe fitting body 1 on the adjacent wall, thereby facilitating the connection of the pipeline. The provided sleeve 3 and the reinforcing rib 4 are used to enhance the overall strength of the U-shaped elbow malleable cast iron pipe fitting body 1 to prevent the U-shaped elbow malleable cast iron pipe fitting body 1 from being deformed during use. The provided installation groove 5 can facilitate the insertion of the pipeline to be connected. The provided threaded sleeve 7 is used to cooperate with the fixing mechanism 6 to fix the pipeline to be connected in the installation groove 5. The operation is simple and convenient. The provided sealing ring 8 can ensure that the connection position between the installed pipeline and the U-shaped elbow malleable cast iron pipe fitting body 1 will not leak. The anti-slip convex pattern provided on the outer wall of the threaded sleeve 7 can enhance the friction force of the outer surface of the threaded sleeve 7, so that no slipping occurs during the rotation of the threaded sleeve 7.

[0026] Example 2

[0027] like Figure 3~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0028] The mounting mechanism 2 comprises a U-shaped rod 21 sleeved on the outside of the U-elbow malleable cast iron pipe fitting body 1, both ends of the U-shaped rod 21 are provided with threads, a connecting plate 22 is installed between the two ends of the U-shaped rod 21, a connecting rod 23 is fixed to the side of the connecting plate 22 away from the U-elbow malleable cast iron pipe fitting body 1, and a mounting plate 24 is fixed to the other end of the connecting rod 23, mounting holes 25 are provided at the four corners of the mounting plate 24, a through hole 27 is provided on the connecting plate 22 corresponding to the position of the U-shaped rod 21, and nuts 26 are screwed on both ends of the U-shaped rod 21.

[0029] In this embodiment, the provided mounting mechanism 2 can facilitate the installation of the U-shaped elbow malleable cast iron pipe fitting body 1 on the adjacent wall, thereby facilitating the connection of the pipeline. At the same time, the position of the mounting mechanism 2 can be adjusted according to the position of the wall to suit different installation scenarios. When the position of the mounting mechanism 2 needs to be adjusted, the nuts 26 at both ends of the U-shaped rod 21 are rotated so that the connecting plate 22 is no longer tightly abutted against the outer wall of the U-shaped elbow malleable cast iron pipe fitting body 1. At this time, the position of the U-shaped rod 21 on the U-shaped elbow malleable cast iron pipe fitting body 1 can be adjusted at will. After adjusting the position of the U-shaped rod 21 according to the position of the wall, the nut 26 is rotated in the opposite direction so that the connecting plate 22 is tightly abutted against the outer wall of the U-shaped elbow malleable cast iron pipe fitting body 1 again, thereby completing the fixing of the position of the mounting mechanism 2.

[0030] The fixing mechanism 6 includes a plurality of symmetrically arranged clamping blocks 61, a through slot 62 connected to the mounting slot 5 is provided at a position corresponding to the clamping block 61 of the U-shaped elbow malleable cast iron pipe fitting body 1, a limiting block 63 is fixed at both ends of the clamping block 61, a limiting slot 64 is provided on the side wall of the through slot 62 at a position corresponding to the limiting block 63, and the limiting block 63 is slidably installed in the corresponding limiting slot 64. The end of the clamping block 61 away from the mounting mechanism 2 is tapered, and the inner wall of the threaded sleeve 7 is inclined.

[0031] In this embodiment, the fixing mechanism 6 is used to cooperate with the threaded sleeve 7 to fix the pipe to be connected in the installation groove 5. The operation is simple and convenient. When the fixing mechanism 6 is working, the pipe to be installed is first inserted into the installation groove 5. Since one end of the clamping block 61 is tapered, when the pipe is inserted into the installation groove 5, the pipe will squeeze the clamping block 61 toward the outside of the U-shaped elbow malleable cast iron pipe fitting body 1, and then the threaded sleeve 7 is rotated. Since the inner wall of the threaded sleeve 7 is inclined, the inner wall of the threaded sleeve 7 will gradually squeeze the clamping block 61 during the rotation process, so that the clamping block 61 is tightly clamped on the outer wall of the pipe until the threaded sleeve 7 cannot rotate, and the installation of the pipe is completed. The operation method is simple and convenient.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
