Problems solved by technology

[0004] The technical problem mainly solved by the present invention is to provide a pipe fitting connecting device, which is used to reserve holes on the floor during construction and connect the sewer pipes between the upper and lower floors, so as to solve the pre-buried upper and lower adjacent floors in the prior art. The connecting device of the pipe fittings is not in the same axis, which causes the problem of inconvenient installation of the sewer pipe

Embodiment 1

[0029] see figure 1 , figure 1 It is an exploded perspective view of Embodiment 1 of the pipe fitting connecting device of the present invention. Such as figure 1 As shown, the pipe fitting connecting device of the present invention includes a connecting body 1 connecting the upper pipe fitting and the lower pipe fitting. The connecting body 1 includes a base part 101 and an upper connecting part 102. 102 is provided with an upper connection hole 103 for connecting the upper pipe fitting and coaxially passing through the lower connection hole. The aperture of the upper connection hole 103 is larger than the aperture of the lower connection hole. Liquids such as water pass through the upper pipe fitting and the pipe fitting connecting device to reach the lower pipe fitting.

[0030] The diameter of the upper connection hole 103 is greater than the outer diameter of the upper pipe fitting. For example, the inner diameter of the upper connection hole 103 is 160mm, and the outer...

Embodiment 2

[0034] see figure 2 , figure 2 It is an exploded perspective view of Embodiment 2 of the pipe fitting connecting device of the present invention. The installation cover 2 comprises a cover surface 202 and a positioning ring 203 arranged on the lower surface of the cover surface 202. The outer diameter of the positioning ring 203 is equal to the inner diameter of the upper connection hole 103, and the positioning ring 203 is inserted in the upper connection hole 103, so that the installation cover 2 Radially fixed.

[0035] In this embodiment, in order to prevent the installation cover 2 from falling into the upper connection hole 103 in the axial direction, the edge of the cover surface 202 is expanded in the radial direction outward to form a flange 204, and the lower surface of the flange 204 is in contact with the upper surface. The upper surface of the connection part 102 is bonded. In other embodiments, the lower end of the inner wall of the upper connection hole 103...

Embodiment 3

[0042] Please also refer to Figure 4 ~ Figure 7 , Figure 4 It is an exploded perspective view of Embodiment 3 of the pipe fitting connecting device of the present invention, Figure 5 yes Figure 4 top view of the seal card, Figure 6 yes Figure 4 Bottom view of the middle seal card, Figure 7 It is an assembled sectional view of Embodiment 3 of the pipe fitting connecting device of the present invention.

[0043] Embodiment 3 is a further improvement on Embodiment 2. Both the left sealing card and the right sealing card are integrally formed by arranging a plurality of flaps 307 sequentially. See Figure 5 , the main part 302 of the sealing card is plate-shaped, and the inner side of the card flap 307 is provided with a semicircular bayonet 305, and the bayonet 305 of the left sealing card and the right sealing card are docked to form a round hole, which is connected to the outer surface of the upper pipe. The diameters are equal; the bayonet 305 of the bayonet expan...

Abstract

The invention relates to a pipe fitting connecting device, which comprises a connecting body. The connecting body comprises a base body portion and an upper connecting portion. A lower connecting hole for connecting a lower pipe fitting is formed in the base body portion, while an upper connecting hole for connecting an upper pipe fitting and coaxially communicating with the lower connecting hole is formed in the upper connecting portion, and the upper connecting hole is larger in diameter than the lower connecting hole. A mounting cap is arranged on an upper end of the upper connecting portion, and an orifice for an upper pipe fitting to pass therethrough is formed in the mounting cap. A sealing clip is arranged on an upper surface of the mounting cap and used for sealing a gap between the orifice and an upper pipe fitting. While an upper pipe fitting is mounted, a bottom end of the upper pipe fitting is inserted into the upper connecting hole through the orifice in the mounting cap, and capable of radially moving in the upper connecting hole; then, the gap between the orifice and the upper pipe fitting is sealed by using the sealing clip. The pipe fitting connecting device provided by the present invention provides a large radial moving range for an upper pipe fitting in the upper connecting hole, and thus can guarantee vertical installation of the upper pipe fitting to an utmost extent.

Description

technical field [0001] The invention relates to the technical field of pipe connection, in particular to a pipe connection device. Background technique [0002] During the construction of new buildings, where there are water supply and drainage requirements such as toilets, kitchens, washing rooms and balconies, the sewer pipes generally have to pass through the floors of the floors. Construction and installation of pipe fittings. One construction method is to reserve a hole on the floor that is 500 mm larger than the outer diameter of the pipe fittings. After the pipe is installed, fill the remaining gaps around the pipe with concrete in three parts. Water may seep in. Another construction method is to pre-embed the pipe fitting connection device during the construction process, and connect the sewer pipe through the pipe fitting connection device. In this construction method, due to the pre-embedding error or the influence of construction, the pre-buried pipe fitting con...
