Description

TECHNICAL FIELD

[0001] The application relates to the technical field of drainage concrete pipes, in particular to a drainage concrete pipe convenient to splice. BACKGROUND

[0002] The concrete pipe is a pipe made of concrete or reinforced concrete and used for conveying fluids such as water, oil and gas. The concrete pipe is divided into four types, namely, plain concrete pipe, ordinary reinforced concrete pipe, self-stress reinforced concrete pipe and prestressed concrete pipe. Compared with the steel pipe, the concrete pipe can save a large amount of steel, prolong the service life, has low construction investment and is convenient to lay and install.

[0003] The existing patent (publication number: CN220037751U) discloses a drainage concrete pipe convenient to splice, and relates to the technical field of drainage concrete pipes. The drainage concrete pipe solves the technical problem that the existing concrete pipe connection mode is too single and not firm enough. The drainage concrete pipe is connected only by winding and surrounding, so that the connection of the concrete pipe is not stable enough. The drainage concrete pipe comprises a drainage concrete pipe body, an upper U-shaped seat and a lower U-shaped seat. The drainage concrete pipe is preliminarily connected at the connection position of two concrete pipes by the upper U-shaped seat and the lower U-shaped seat. The sealing ring is sealed under the extrusion expansion of the upper U-shaped seat and the lower U-shaped seat, so as to prevent leakage at the connection position of the concrete pipe. The connection position is more tightly and firmly connected by the tensioning connection assembly. The concrete pipe is doubly limited and fixed by the buckling connection of the upper U-shaped seat and the lower U-shaped seat. The connection end of the concrete pipe is sealed, and the stability of the connection between the concrete pipes is improved.

[0004] The pipe in the above-mentioned comparative document needs to use a wrench and other tools to twist the bolt and realize the locking effect when splicing. In order to further optimize the convenience of the splicing process, the application provides a drainage concrete pipe convenient to splice. CONTENT OF THE UTILITY MODEL

[0005] In view of the defects of the prior art, the application provides a drainage concrete pipe convenient to splice. The drainage concrete pipe can realize quick splicing without the aid of a wrench and other tools, and is more practical.

[0008] Further, the inner wall of the guide groove is fixedly connected with a sealing gasket, and the outer surface of each sealing gasket is provided with a through hole corresponding to the wedge-shaped insertion groove.

[0009] Through the above scheme, the sealing property of the spliced part can be ensured, and the probability of water leakage is reduced.

[0010] Further, the diameter value of the locking rod corresponds to the diameter value of the locking hole.

[0011] Through the above scheme, the locking rod is inserted into the locking hole to limit the wedge-shaped insertion block, so that the stable splicing effect can be achieved.

[0012] Further, the size value of the wedge-shaped insertion block corresponds to the size value of the wedge-shaped insertion groove.

[0013] Through the above scheme, when the wedge-shaped insertion block is inserted into the wedge-shaped insertion groove, the two drainage concrete pipe bodies can be stably spliced, and the situation of rotation after splicing of the two drainage concrete pipe bodies is prevented.

[0014] Further, the locking rod, the rectangular plate, the support, the guide ring and the sealing ring are all made of stainless steel.

[0015] Through the above scheme, the material of the assembly is limited, which can have certain strength and corrosion resistance, so as to ensure the stability of splicing.

[0016] Further, the compression spring is made of titanium alloy.

[0018] Further, one end of each of the rotating handles is fixedly connected with a lever, and the outer surface of each of the levers is coated with a non-slip layer.

[0019] Through the above scheme, the rotating handle can be conveniently rotated, and the lock rod can be conveniently removed from the wedge-shaped slot, thereby facilitating quick splicing.

[0020] Further, the outer surface of the guide ring is fixedly connected with a sealing ring, and the sealing ring is matched with the inner wall of the guide groove.

Through the cooperation of the lock rod, the rectangular plate, the bracket, the compression spring, the rotating handle and the limiting ring, the two spliced drainage concrete pipe bodies can be locked together. During locking, a wrench or other tools are not needed, and the lock rod can be moved up or down by rotating the handle, thereby achieving quick locking. Compared with the device in the comparative document, the device has outstanding advantages in splicing and locking of the drainage concrete pipe body, and is more practical.
