Description

Drainage pipe joint structure

The present invention relates to a drain pipe joint, and more particularly to a drain pipe joint structure of a water collecting tank.

The structure of a drain pipe joint of a conventional water collecting tank, as shown in Figs. 8 and 9, the drain pipe joint is composed of upper and lower pipe bodies 40 and 50, and the top end of the upper pipe body 40 is outwardly expanded. The abutting portion 41 has a tube wall 42 extending downward from the abutting portion 41, and the lower tube body 50 is fitted outside the tube wall 42 of the upper tube body 40. There is a top portion 51 and a set of wall 52 extending downward from the top portion 51. The drain pipe joint is formed by the upper pipe body 40 being inserted into the drain hole 61 of the sump 60 and fixed to the abutment portion 41. The bottom of the sump 60 is provided on the bottom of the sump 60, and the lower end of the sump 60 is provided on the wall of the upper tube 40, and the lower tube 50 is provided with a water pipe 62 to be sleeved on the assembly wall 52. Finally, the drain joint, the sump 60 and the water pipe 62 are adhered and fixed by an adhesive, and the whole assembly and joint of the structure can be completed. With the above structure, the concrete can form a drain joint structure of the sump.

Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reasons are as follows: (1) Above its conventional knowledge, the lower pipe bodies 40 and 50 are not matched and can be clamped and fixed to each other. Although the structure is adhered and fixed by the adhesive, the lower tube body 50 is easily loosened and dropped from the upper tube body 40 for a long time, which causes inconvenience in use and reduces the use thereof. Use sex.

(2) It is conventionally known that there is no additional recess in the wall edge of the tubular body 40 and the lower tubular body 50, and the upper tubular body 40 is disposed in the sump 60 to produce a joint or When the adhesive between the two is hardened and peeled off due to long-term exposure, a gap is formed between the upper tube 40 and the drain hole 61, so that water easily flows from the abutting portion 41 of the upper tube 40, and accumulates in The abutting portion 51 of the upper tubular body 50 is further leaked outward, causing the use of the defect.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention is to provide a drain pipe joint structure for a water collecting tank in view of the above-mentioned shortcomings existing in the prior art.

The above structure comprises: an upper tube body and a lower tube body, the upper tube system is formed by combining a ring-shaped piece body, and the two ends of the ring-shaped piece body are respectively provided with a first hook portion and a second hook The first and second hook portions of the phase buckle are stamped with a plurality of bumps from the outside to form a tapered inner tube wall, and the outer diameter of the inner tube wall is provided with two longitudinal water guiding recesses. a groove, and a convex ring edge is folded outwardly at the top end of the inner tube wall, and the lower tube body is also formed by a ring-shaped piece body, and the two ends of the annular piece body are mutually buckled. a hook portion and a fourth hook portion, and forming a tapered outer wall with the inner tube wall of the upper tube body, the top end of the outer tube wall extending outwardly to have a top abutting edge, and the outer tube wall and the inner portion A locking portion for positioning the card is provided between the pipe walls.

According to the effect of the prior art: (1) The upper tube body and the lower tube system are provided with a locking portion fixed on the inner tube wall and the outer tube wall, so that the two are combined with the drainage arranged in the sump In the case of holes, a more stable combination structure can be achieved, and the practicality of use can be increased.

(2) The outer diameter of the inner wall of the upper pipe body is concavely provided with a water guiding groove, and when the upper pipe body is set in the sump, the water flow can also pass through the water guiding body due to assembly or squeezing agent exposure and hardening and peeling. The groove is introduced into the lower tube body to avoid the inconvenience of use due to the overflow of the water, thereby improving the practicality of the drainage and drainage.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following [simplified description of the drawings] as follows: First, please refer to Figures 1, 2 and 3 A drain pipe joint structure of a water collecting tank, comprising: an upper pipe body 10 and a lower pipe body 20, wherein the upper pipe body 10 is formed by combining an annular piece body, and the annular piece body is provided at two ends One of the first hook portion 11 and one second hook portion 12 are mutually snapped, and the phase buckle The first and second hook portions 11 and 12 are formed by pressing a plurality of bumps 13 from the outside to form a fixed shape, and the annular sheet body is formed into a tapered inner tube wall 14 having an outer diameter of the inner tube wall 14 Two longitudinal water guiding grooves 15 are provided, and a convex ring edge 16 is folded outwardly at the top end of the inner tube wall 14, and the lower tube body 20 is also combined by an annular sheet body. The first end is provided with a third hook portion 21 and a fourth hook portion 22 which are mutually buckled, and cooperate with the inner tube wall 14 of the upper tube body 10 to form a tapered outer tube wall 23, the outer tube wall 23 The top end extends outwardly from the top edge 24, and the outer tube wall 23 and the inner tube wall 14 are provided with snap-fit portions 231, 141 positioned relative to each other.

For the structure of the structure, please refer to the second to seventh figures. The set of joints is arranged on the drain hole 31 of the sump 30, and the upper tube 10 is sleeved on the drain hole 31 by the inner tube wall 14. The lower tubular body 20 is disposed on the inner tube wall 14 of the upper tubular body 10 from the bottom to the top and abuts against the abutting edge 24 by abutting against the outer circumference of the drain hole 31. In the bottom side wall of the sump 30, the buckle portion 231 of the outer tube wall 23 and the fastening portion 141 of the inner tube wall 14 are locked and fixed, and the tube body 20 is connected to the lower portion to connect a drain tube. In order to complete the assembly of the drain pipe joint, when it rains, the rainwater flows into the inner pipe wall 14 of the upper pipe body 10 along the sump 30, and is discharged from the drain pipe to reach the water transport and discharge.
