Embodiment 1
[0071] Such as figure 1 As shown, the component symbol 1 shows a western-style toilet, the component symbol 2 shows the body part of the western-style toilet 1, the component symbol 3 shows a toilet lid as an example of an opening and closing body, and the component symbol 4 shows a toilet seat. The toilet lid 3 and the toilet seat 4 are connected openably and closably to the main body 2 via the fluid damping hinges 5 and 6 of the present invention. For example, the toilet lid 3 can be opened and closed with the main body 2 through the fluid damping hinge 5 , and the toilet seat 4 can be opened and closed with the main body 2 through the fluid damping hinge 6 . Actually, the following cylindrical housing 10 of the fluid damping hinges 5 and 6 is constructed by being assembled to the main body 2 through the cover parts 7 and 8 assembled to the main body 2 , and the cover part 7 is omitted in the following description. ,8. Furthermore, the covering parts 7 and 8 may be omitted...

Provided is a fluid damping hinge with simple structure and low cost, particularly suitable for the opening and covering of the western style closestool. The fluid damping hinge comprises a cylindrical housing which, with a fluid chamber, is installed to one side of the body, a rotating rod which is rotatably installed to a position in the central shaft direction of the cylindrical housing via a sealing member and is limited to axial movement only, with the assembling apparatus of the opening-closing body being arranged at the protruding portion of the cylindrical housing, a pressure valve guide portion which is arranged at a position of the rotating rod inside the fluid chamber, and a pressure valve which, arranged at the pressure valve guide portion, can also be movably arranged in a pressure valve guide groove. A fluid accelerating apparatus is arranged upon the pressure valve guide portion to face the pressure valve. Moreover, the pressure valve guide groove is slantly arranged facing internal periphery of the fluid chamber.
Description
technical field [0001] The present invention particularly relates to a fluid damping hinge, which is suitable for the opening and closing bodies of western-style toilets such as toilet lids and toilet seats. In addition to being able to open and close the main body, it can be kept in an upright state, and at the same time, when the opening and closing body is closed, it will not Fall quickly. Background technique [0002] In the conventional technology, the toilet lid and the toilet seat of the western-style toilet are assembled so that the toilet lid can be opened and closed relative to the body portion by the hinge for opening and closing located at the rear side of the body portion of the toilet body. In particular, when closing, the toilet lid will drop rapidly and collide with the toilet seat, causing loud noises, the damper hinge for buffering the rapid drop between the toilet lid and the toilet seat is as described in the following patent document 1. Shown as a known...
