Description

Technical Field

[0001] The utility model belongs to the technical field of sewer pipe accessories, in particular to a novel pipe connecting device. Background Art

[0002] When connecting the drain fittings of traditional household kitchen sinks, washbasins or washing machines to the drain pipe, most of them are simple direct-insertion types without sealing covers or with simple upper covers fixed with glue. The direct insertion method cannot achieve a tight fit, which not only causes sewer odors to overflow, but also causes problems such as foam, water backflow, and mosquitoes crawling out.

[0003] For example, the Chinese patent with announcement number CN109723109A discloses an odor-proof sealed connection joint for a sewer pipe, which includes an upper connecting pipe and a lower connecting pipe. The upper connecting pipe is composed of a main body, a threaded pipe, a gasket, a rubber pad and a tightening cover. The main body is composed of a thick pipe with a thin pipe connected to the upper end. The threaded pipe is connected to the upper part of the thick pipe part of the main body. The gasket is sleeved on the thin pipe part of the main body. The tightening cover is connected to the threaded pipe through a thread. The rubber pad is C-shaped, sleeved on the thin pipe part of the main body, located above the gasket, and the rubber pad is in contact with the tightening cover. The lower connecting pipe is composed of a thick pipe with a thin pipe connected to the upper end of the thick pipe, and the thin pipe part of the lower connecting pipe is inserted into the thick pipe of the main body of the upper connecting pipe. The thin tube part of the main pipe is inserted into the basin drain pipe, and the thick tube part of the lower connecting pipe is sleeved on the sewer pipe and sealed with sealant. The rubber pad is squeezed by tightening the tightening cover. The extruded rubber pad tightly connects the end of the basin drain pipe to the upper connecting pipe, thereby realizing a sealed connection between the basin drain pipe and the sewer pipe.

[0004] The above technical solution has the following defects: the lower connecting pipe is socketed with the sewer pipe, and sealant is needed to bond the two together, which makes it inconvenient for users to disassemble, replace or repair them later; in addition, the sealant has a short service life and is easily aged and falls off, resulting in poor sealing effect after long-term use.

[0033] The present invention will be further described below in conjunction with specific embodiments:

[0034] like Figures 1-9 As shown: A new type of pipe connecting device, including a water cylinder 1, a locking sleeve 2, an elastic member 3 and a sealing device 4, the locking sleeve 2 is arranged at the upper opening of the sewer pipe, and the locking sleeve 2 is sleeved on the outside of the water cylinder 1, the elastic member 3 is located between the locking sleeve 2 and the water cylinder 1, and the water cylinder 1 is always away from the locking sleeve 2 by virtue of the elasticity of the elastic member 3, the sealing device 4 is movably arranged at the lower end of the water cylinder 1, and is located below the locking sleeve 2, the lower end of the water cylinder 1 is provided with an anti-falling member 5 to prevent the sealing device 4 from falling off, specifically, the anti-falling member and the water cylinder are connected to each other by a threaded connection, when the water cylinder 1 is away from the locking sleeve 2, the sealing device 4 will block the gap between the water cylinder 1 and the sewer pipe. The upper end of the drain cylinder is used to connect the drain pipe of the kitchen sink, washbasin or washing machine, and the lower end thereof extends into the drain pipe, and the locking sleeve is sleeved on the upper opening of the drain pipe. When the drain cylinder moves away from the drain pipe through the elastic part, the two ends of the sealing device abut against the locking sleeve and the anti-slip part, and the drain cylinder moves upward, which will drive the sealing device to deform. The sealing device will seal the gap between the drain cylinder and the inner wall of the drain pipe, thereby playing a role in sealing and preventing backflow. The operation is simple, the elastic part is a spring, and the elastic part is sleeved on the outside of the drain cylinder.

[0035] In the above-mentioned new pipe connection device, the water cylinder 1 has an inner and outer part, which can be threadedly connected or integrally formed. A locking block 11 is provided on the outer wall of the water cylinder 1, and a locking ring 12 is provided on the inner side of the locking sleeve 2 to facilitate the abutment and clamping of the locking block 11. The locking ring 12 is provided with a locking groove 13 to facilitate the passage of the locking block 11. A guide surface 14 is provided on one side of the locking groove 13, and a blocking block 15 is provided on the other side. Specifically, this is to ensure that the water cylinder can only be unlocked in one direction, which is convenient for the operator to use.

[0036] In the above-mentioned new pipe connection device, the locking block 11 is an L-shaped structure. Specifically, this is to further facilitate the use of operators. Simply put, in the initial state, the L-shaped short side of the locking block is stuck on the locking ring, and part of the locking block is located in the locking groove; when sealing is required, it is only necessary to rotate the water cylinder so that the L-shaped short side of the locking block is disengaged from the locking ring and enters the locking groove to complete the unlocking. Continue to rotate, and the lower side of the locking block will be against the upper side of the locking ring.

[0037] In the above-mentioned new pipe connection device, the sealing device 4 includes an annular elastic diaphragm 41 and an abutment ring 42. The annular elastic diaphragm 41 is located between the abutment ring 42 and the anti-slip component 5. Specifically, the abutment ring is designed to abut against the locking sleeve. This is to allow the annular elastic diaphragm to deform better. When squeezed, the middle end of the annular elastic diaphragm protrudes outward and contacts the inner wall of the sewer pipe.

[0038] In the novel pipe connection device described above, there are two annular elastic diaphragms 41 and two abutting rings 42 , and the annular elastic diaphragms 41 and the abutting rings 42 are arranged in sequence from bottom to top. Specifically, this is to further improve the sealing performance.

[0039] In the above-mentioned new pipe connection device, the lower end of the locking sleeve 2 is provided with a sewer pipe sleeve opening 21, and a lip sealing ring 22 is provided in the sewer pipe sleeve opening 21. Specifically, this is to further play a sealing role. The lower opening of the lip sealing ring is sleeved on the upper opening of the sewer pipe.

[0040] In the above-mentioned new pipe connection device, a rotating sleeve 6 connected to the locking sleeve 2 is further provided on the outer side of the water cylinder 1. The rotating sleeve 6 can drive the water cylinder 1 to rotate, and the lower end of the rotating sleeve 6 is provided with a hook portion 1 61, and the locking sleeve 2 is provided with a hook portion 2 62 used in conjunction with the hook portion 1 61. The hook portion 1 61 and the hook portion 2 62 are both provided with a guide slope 63. Specifically, this is to facilitate the installation between the rotating sleeve and the locking sleeve.

[0041] In the above-mentioned new pipe connection device, a guide groove 64 is provided on the inner side of the rotating sleeve 6, a guide block 65 used in conjunction with the guide groove 64 is provided on the outer side of the water cylinder 1, and anti-slip grooves 66 are provided on the outer side of the rotating sleeve 6. Specifically, this is to facilitate the rotating sleeve to drive the water cylinder to rotate.

[0042] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
