Abstract

The utility model relates to a sitting WC pan bottom seal ring, comprising a seal pipe with an inlet and an outlet, inner clay arranged on the inner wall of the inlet of the seal pipe and outer clay on the outer wall of the inlet of the seal pipe; the inlet of the seal pipe is provided with a first face extended horizontally; the first face is adjacent with a second face; the second face is adjacent with a third face; the third face is adjacent with a forth face; the angle Beta between the second face and the third face is larger than 90 degrees and smaller than 180 degrees; the angle Gamma between the third face and the forth face is larger than 180 degrees and smaller than 270 degrees. The shearing force produced when the clay is squeezed is buffered to the largest extent; the clay can be extended without breaking and the period of usage of the clay is prolonged.

Description

Toilet bowl bottom sealing ring

Technical field

The utility model relates to the sealed pipe fittings that is connected between a kind of flush toilet and the sewer pipe.

Background technology

Prior art is shown in accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, comprise the sealed tube with import and outlet, the clay that is arranged on sealed tube import department, the import department of described sealed tube has first that horizontal direction is extended, described clay is connected with this first face, first angle with second is the right angle, angle between second and the 3rd is the right angle, and the angle between the 3rd and the fourth face is the right angle.When toilet bowl was installed on the sealed tube, the clay on top was under pressure, and pressure passes to crossing right angle and is transformed into shearing force, then clay be subjected to shearing force can cause the fracture, the fracture of clay has reduced the application life of clay.

Summary of the invention

The purpose of this utility model is to provide a kind of toilet bowl bottom sealing ring, and it can improve the application life of the clay that is connected with sealed pipe fittings in the sealing ring of toilet bowl bottom.

The technical solution of the utility model is: a kind of toilet bowl bottom sealing ring, comprise sealed tube with import and outlet, be arranged on the interior clay of sealed tube import department inwall and the outer clay of outer wall, the import department of described sealed tube has first that horizontal direction is extended, described first adjacently has second, second adjacent the 3rd, the 3rd adjacent fourth face, described second, the 3rd, fourth face is the inwall of sealed tube, on axial cross section, second, less than 180 degree, the 3rd the 3rd angle γ that constitutes with fourth face spends less than 270 greater than 180 degree the second angle β of the 3rd formation greater than 90 degree.

The utility model compared with prior art has following advantage:

Because second is not the right angle with the 3rd intersection, the 3rd intersection with fourth face, therefore cushioned the shearing force that produces when clay is extruded to greatest extent, clay can be extended do not rupture, improved application life.

The specific embodiment

Referring to accompanying drawing 1 to accompanying drawing 4, a kind of toilet bowl bottom sealing ring, comprise sealed tube [2] with import and outlet [3], be arranged on the interior clay [1] of sealed tube [2] import department inwall and the outer clay [8] of outer wall, the import department of described sealed tube [2] has first [4] that horizontal direction is extended, described first [4] adjacent second [5], second [5] adjacent the 3rd [6], the 3rd adjacent fourth face [7], described second [5], the 3rd [6], fourth face [7] is the inwall of sealed tube [2], on axial cross section, second [5], the second angle β that the 3rd [6] constitute spends less than 180 degree greater than 90, and the 3rd [6] are spent less than 270 greater than 180 degree with the 3rd angle γ that fourth face [7] constitutes.

Less than 180 degree, described first [4] have transition arc with the intersection of second [5] to the first angle α of described first [4] and second [5] structure face greater than 90 degree.The shearing force that transition arc produced in the time of can cushioning clay to greatest extent and be extruded can be extended clay and is not ruptured, and has improved application life.Arc transition has strengthened the surperficial bond area of clay and sealed tube simultaneously, thereby has further improved the seal degree of sealed tube and clay.

Claims

1, a kind of toilet bowl bottom sealing ring, comprise sealed tube [2] with import and outlet [3], be arranged on the interior clay [1] of sealed tube [2] import department inwall and the outer clay [8] of outer wall, the import department of described sealed tube [2] has first [4] that horizontal direction is extended, it is characterized in that: described first [4] adjacent second [5], second [5] adjacent the 3rd [6], the 3rd adjacent fourth face [7], described second [5], the 3rd [6], fourth face [7] is the inwall of sealed tube [2], on axial cross section, second [5], the second angle β that the 3rd [6] constitute spends less than 180 degree greater than 90, and the 3rd [6] are spent less than 270 greater than 180 degree with the 3rd angle γ that fourth face [7] constitutes.
