Problems solved by technology

On the one hand, due to the slight difference in the front and back installation directions of the damper, it is easy to cause wrong installation and wrong installation in the production process; on the other hand, at least two dampers are usually installed on the toilet cover or door leaf, two When the damper is installed symmetrically, due to the different directions, it is necessary to develop different molds, which not only costs more, but also increases the variety of parts, which is easy to be confused in the selection of actual products and affects its versatility

[0063] The first embodiment (the oil passage of the rotating shaft is controlled by two shift blocks)

[0064] Such as Figure 1 to Figure 17 As shown, a positive and negative two-way damping mechanism of this embodiment includes a housing 10 provided with an oil chamber 11, a rotating shaft 20 that is sealed and rotated with the oil chamber 11 of the housing 10, and at least one fixedly arranged on the A baffle 22 between the housing (10) and the rotating shaft (20) for disturbing and damping oil, the baffle 22 divides the oil chamber 11 into at least a first oil chamber and a second oil chamber, and It includes a connecting channel 31a connecting the first oil chamber and the second oil chamber. When the rotating shaft 20 rotates clockwise, the baffle plate 22 moves the damping oil in the first oil chamber so that the first oil chamber The damping oil in the oil chamber flows from the connecting passage 31a to the second oil chamber, so that the oil pressure in the first oi...

[0077] The second embodiment (the oil passage of the rotating shaft is controlled by a shift block)

[0078] Such as Figure 18 to Figure 31 As shown, the main difference between the forward and reverse bidirectional damping mechanism of this embodiment and the first embodiment is that: in this embodiment, the shifting block includes one, and the shifting block includes a first end and a second end; When the rotating shaft 20 rotates clockwise from the initial position, the first end of the shift block cooperates with the housing 10 to reduce the flow cross-section at one end of the connecting passage; when the rotating shaft 20 rotates counterclockwise from the initial position , the second end of the shifting block cooperates with the housing 10 to reduce the flow cross-section of the other end of the connecting channel 31b.

[0079] Other embodiments can also be used, when the rotating shaft 20 rotates clockwise from the initial position, the first end of the shift block c...

Abstract

The invention discloses a positive and negative bidirectional damping mechanism and a toilet stool cover plate with the same. The mechanism comprises a shell, a rotation shaft, and at least one bafflefixedly arranged between the shell and the rotation shaft and used for disturbing damping oil, wherein an oil cavity is divided into at least one first oil cavity and a second oil cavity by the baffle. The mechanism also comprises a connection channel communicating the first oil cavity with the second oil cavity; when the rotation shaft is rotated clockwise, the baffle plate stirs the damping oilin the first oil cavity, so that the damping oil of the first oil cavity flows to the second oil cavity via the connection channel, and thus the oil pressure of the first oil cavity is higher than that of the second oil cavity; when the rotation shaft is rotated anticlockwise, the baffle stirs the damping oil in the second oil cavity, so that the damping oil in the second oil cavity flows to thefirst oil cavity via the connection channel, and thus the oil pressure of the second oil cavity is higher than that of the first oil pressure; therefore, the positive and negative damping effect is achieved, mistaken installation and poor installation during the assembling processing of the damper can be avoided, the universal compatibility is better, the standardization of products is easy to promote, the varieties of parts are reduced, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of bathroom technology, in particular to a forward and reverse bidirectional damping mechanism and a toilet cover with the damping mechanism. Background technique [0002] With the improvement of people's living standards, the damping mechanism is widely used in daily life because it can be buffered and has the characteristics of impact resistance and low noise, such as on the toilet cover and door leaf. Most of the existing damping mechanisms on the market realize the damping function through hydraulic pressure, that is, a high-pressure oil chamber and a low-pressure oil chamber are formed in the damper during the opening process, and the damping oil slowly penetrates from the high-pressure oil chamber to the low-pressure oil chamber, thereby achieving slow fall and silence the goal of. [0003] A traditional damper usually includes a shell that can be filled with damping oil and a rotating shaft that is sealed and ...
