Description

Technical Field

[0001] This utility model belongs to the technical field of drainage pipe connection joints, specifically a drainage pipe connection joint for engineering construction. Background Technology

[0002] A drain pipe splice is the part that connects drain pipes together. It is typically used to connect two different pipes. Drain pipe splices allow for a tighter connection between adjacent pipe sections, thereby improving the structural strength of the pipe connection.

[0003] Many existing drainage pipe connections use flange connections. Flange connections require fixing two pipes or fittings to separate flanges, placing a gasket between them, and finally tightening the flanges with bolts. This process involves precise alignment and tightening of multiple components to ensure a tight seal and stability. Therefore, disassembly and installation require considerable time and effort to ensure correct installation and tightening of all components, increasing operational complexity. Furthermore, bolts and nuts may rust over time due to humid environments or the presence of corrosive media. When disassembling the connection is needed for later maintenance or repairs, rusted bolts and nuts can be difficult to remove because rust increases friction and tightening force, making disassembly more strenuous and reducing ease of use.

[0004] Therefore, we propose a connection joint for drainage pipes used in engineering construction. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage pipe connection interface for engineering construction so that drainage pipe one and drainage pipe two can be quickly disassembled and connected without the use of bolts and nuts, thereby improving the convenience of use.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A connection joint for drainage pipes used in engineering construction includes a first drainage pipe, a second drainage pipe, a connection joint mechanism, a positioning mechanism, and a connecting sleeve. The connection joint mechanism includes a clamping block, which is fixedly connected to the outer surface of the opening of the first drainage pipe. A sealing rubber gasket is fixedly connected to the lower end of the clamping block on the outer surface of the first drainage pipe. An annular groove is fixedly connected to the upper outer surface of the clamping block. An annular groove is formed between the inner surface of the annular groove and the upper outer surface of the clamping block. A groove is formed on the inner sidewall of the annular groove, and a through hole is formed on the inner sidewall of the groove. The connecting sleeve is fixedly connected to the surface of the second drainage pipe, and a positioning hole is formed on the upper outer side of the connecting sleeve.

[0008] The positioning mechanism includes a positioning pin, the outer surface of which is slidably connected to the inner surface of the groove. A spring is fixedly connected to one side of the positioning pin near the through hole. The end of the spring away from the positioning pin is fixedly connected to the inner sidewall of the groove. A pull rod is fixedly connected to the middle of the side of the positioning pin near the spring. The pull rod extends through the middle of the spring and the through hole to the outside and is fixedly connected to a pulling block.

[0009] Furthermore, the outer surface of the positioning pin is inserted into the inner surface of the positioning hole, and the length of the positioning pin is greater than the depth of the positioning hole.

[0010] Furthermore, the number of grooves is four, and the four grooves are equidistantly arranged on the inner sidewall of the annular groove.

[0011] Furthermore, the number of positioning holes is four, and the four positioning holes are equidistantly arranged on the upper outer surface of the connecting sleeve.

[0012] Furthermore, the outer surface of the clamping block is slidably connected to the inner surface of the connecting sleeve.

[0013] Furthermore, the outer surface of the upper end of the connecting sleeve is inserted into the inner surface of the annular groove.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] In this invention, when connecting drainage pipe one and drainage pipe two, first pull the pulling block to cause the pull rod to drive the positioning pin to compress the spring, so as to pull the positioning pin into the groove. Then, insert the lower opening of drainage pipe one into the interior of drainage pipe two. At this time, drainage pipe one will drive the clamping block and sealing rubber gasket to slide into the connecting sleeve, and compress the sealing rubber gasket to seal the connection between drainage pipe one and drainage pipe two inside the connecting sleeve, until the top of the connecting sleeve extends into the annular groove. At this time, the positioning hole and the groove are aligned. Then, the pulling block can be released, and the spring will drive the positioning pin to insert into the positioning hole under the elastic restoring action, so as to position and fix the connection between drainage pipe one and drainage pipe two. With the cooperation of the above structure, drainage pipe one and drainage pipe two can be quickly disassembled and connected without the use of bolts and nuts, improving the convenience of use.
