Connecting structure for floor drain core and floor drain body

Abstract

The invention discloses a connecting structure for a floor drain core and a floor drain body. The connecting structure comprises the floor drain body and the core; the inner wall of the floor drain body is provided with a clamping groove, the outer wall of the core is provided with a plurality of convex blocks which can be connected with the clamping groove in a clamped mode, an isobathic annular groove is adopted as the clamping groove, and upper notches are formed in the positions, corresponding to the convex blocks of the core, of the upper portion of the annular groove; the height of the two ends of each convex block is smaller than that of the middle of the convex block. The connecting structure for the floor drain core and the floor drain body has the advantages that disassembly and assembly are convenient, no influence can be caused to water entry of the floor drain core, and the structure is simple and practical.

Description

technical field [0001] The invention relates to a floor drain, in particular to a connection structure between a floor drain core and a body. Background technique [0002] The floor drain is generally composed of a floor drain body, an anti-odor and insect-proof core and a cover plate. The floor drain body is mostly made of metal, while the floor drain core is made of plastic material, and is realized by the protrusion on the outer wall of the floor drain core and the card slot on the inner wall of the floor drain body. Snap connection. [0003] Here, if figure 1 with 2 As shown, the grooves on the inner wall of the floor drain body 1' above are several guide grooves 11' evenly distributed in the circumferential direction, and each guide groove 11' is provided with a notch 111' where the core 2' bump 21' snaps in. The bottom of the guide groove 11' extends obliquely downward along the inner wall of the floor drain body 1' and its depth is continuously increased. When ass...

Problems solved by technology

But at present, for the convenience of disassembly and assembly, the water inlet 23' of the core 2' is generally provided with a "one"-shaped or "S"-shaped bar 24', wherein the "one"-shaped structure like figure 2 As shown, when disassembling, two fingers are inserted into the water inlet to grasp the horizontal bar 24' to rotate the core 2', not only the range of force is small, but the operation is troublesome. In the middle part, the torque is very small when turning. When the floor drain is stuck tightly after long-term use, it is difficult to turn the core 2', which brings great inconvenience to actual use.

In addition, the thin horizontal bar 24' made of plastic is easy to age and become brittle after long-term use, and it is easy to break when the force is too large, resulting in the complete scrapping of the core 2'

[0007] In addition, the above "one"-shaped (or "S"-shaped) bar 24' straddles the water inlet 23', which will hinder the water entry of the floor drain core 2' into the water inlet 23', not only to a certain extent It affects the drainage performance, and it is easier to be stuck by hair and other sundries and cause blockage
