Title is arranged in the shaft 20, and what two limited block 30 was centrosymmetric is arranged on the shell 10.
In the present embodiment, the limited block 30 and the convex block 41 are axis body structure.
The present embodiment further includes lavatory lid (not shown) and for lavatory lid to be fixed on toilet seat body turnablely
On bracket (not shown), lavatory lid further includes upper cover and seat ring, and circumferentially limit connects the shell 10 with the bracket, institute
The damping mechanism with temporary limit function, upper cover and seat ring and respective damping can be all arranged in the upper cover and seat ring for stating cover board
The circumferential limit connection of the shaft 20 of mechanism, so that the upper cover of cover board and seat ring can be rotated and can be realized voluntarily on bracket
It stands.
The assembly of the present embodiment and the course of work are as follows:
Shaft 20 by the front opening 13 of the shell 10 protrudes into the inner cavity 11 of shell and by the open rearward end 14
The shell 10 is stretched out, by limited step 15 to the axial limiting of blade 21 to 20 axial limiting of shaft, the shaft
20 are cased with sealing ring 23 and seal cooperation with the limited step 15, and diaphragm seal 61 and fixed lid 60 are successively fixedly mounted on shell
At 10 front openings 13 and then forming inner cavity 11 simultaneously makes 20 axial limiting of shaft in shell 10, then by convex block 41 and limiting slot 22
Opposite position, and end cap 40 is packed by the rear end of shaft 20 and is fixed on 10 open rearward end 14 of shell, and then limits convex block 41
The assembly of damping mechanism is completed in shaft 20 in position, then the shell 10 of damping mechanism is packed into bracket, cover board (upper cover and seat ring)
It is installed on bracket by the rotation of shaft 20, to complete the assembly of damping mechanism and cover board.
When original state namely when cover board is in lid conjunction state, as shown in figure 5, the convex block 41 and the limited block 30
It is staggered in circumferential direction and is spaced setting, when cover board is overturn, shaft 20 is rotated counterclockwise with cover board, and convex block 41 is with the shaft synchronous inverse time
Needle rotation, as shown in fig. 6, limited block 30 is common in elastic arm 12 and C-shaped elastic slice 50 when convex block 41 and limited block 30 abut against
Certain resistance is generated to the movement of convex block 41 under elastic acting force, so that the rotation to shaft 20 generates certain resistance, at this point, turning over
The external force of hub cap plate need to make shaft 20 overcome the common elastic acting force of elastic arm 12 and C-shaped elastic slice 50 so that convex block 41 enough
Can pushing tow limited block 30 make limited block 30 move resigning radially outward along shell 10, as shown in fig. 7, the convex block 41 overcomes
Elastic arm 12 and the common elastic acting force of C-shaped elastic slice 50 push convex block 41 to be moved to resigning position, continue to rotate counterclockwise and turn
Axis 20, as shown in figure 8, convex block 41 crosses the limited block 30, limited block 30 is made in elastic arm 12 and the common elasticity of C-shaped elastic slice 50
The position that resets and can extremely be limited to convex block 41 is moved under firmly inside along the radial direction of shell 10, at this point, if cover board is turned over
The angle turned is not greater than 90 degree, and cover board will make shaft 20 along having revolution trend clockwise under self gravity, cover board not by
When to enough external forces, convex block 41 is not enough to overcome elastic arm 12 and the common elastic acting force of C-shaped elastic slice 50 and pushing tow limits
Position block 30 is mobile, and therefore, limited block 30 carries out limit to convex block 41 to circumferentially rotate progress to shaft 20 by convex block 41
Limit, and then cover board is made not continue to turn round under self gravitation effect, to realize temporary limit function.
Embodiment 2:
As shown in Figure 9 and Figure 10, the distinctive points of the present embodiment and above-described embodiment are, 10 open rearward end of shell,
The shell 10 is protruded by the open rearward end of shell 10 in front end closing, the front end of the shaft 20, and the rear end of the shell 10 is opened
It is sealedly connected at mouthfuls 14 and the gland 70 of axial limiting is carried out to the shaft to form the inner cavity 11, after the shaft 20
End, which is stretched out the gland 70 and sealed with 70 phase of gland, to be cooperated, and in the present embodiment, the limited block 30 is set to the pressure
On the side wall of lid 70, specifically, gland 70 is tubular structure, the structure and principle of other not described parts are consistent with the above, this
In repeat no more.
The above, only the utility model preferred embodiment, therefore, it cannot be limited according to, and the utility model is implemented
It is practical new to should still belong to this for range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual
In the range of type covers.
