Description

Wall-hung type closestool fixing device
Technical Field
The invention relates to the field of wall-mounted toilets, in particular to a wall-mounted toilet fixing device.
Background
The wall-hung toilet C is a toilet in which the toilet is directly hung on the installation base W (wall or tank fixing bracket) and the bottom of the toilet is not in contact with the ground, so that the space of the toilet can be saved, and the wall-hung toilet C is generally fixed on the installation base by the fixing device.
As shown in fig. 1, a conventional wall-mounted toilet bowl fixing device is composed of a body 1', a threaded sleeve 2' sleeved in the body 1' and a screw 3', wherein the threaded sleeve 2' is provided with an inward concave cambered surface 21', and the tail end of the screw 3' opposite to the head is in a conical surface structure. When the wall-hung toilet bowl fixing device is used for fixing the wall-hung toilet bowl C, as shown in fig. 2, the body 1' is arranged in the installation cavity C1 of the wall-hung toilet bowl C, the installation cavity C1 is provided with a fixing hole C11 penetrating through the back surface of the wall-hung toilet bowl C and an installation hole C12 penetrating through the top surface or the side surface of the wall-hung toilet bowl C, the threaded sleeve 2' is connected with the screw rod S fixed on the installation substrate W, then the threaded sleeve 2' penetrates through the fixing hole C11 and then penetrates into the body 1', and finally a spanner stretches into the installation cavity C1 from the installation hole C12 to screw the screw 3' into the body 1' and enable the tail end of the screw 3' to clamp the concave arc surface 21' of the threaded sleeve 2' so as to achieve locking. However, when the wall-mounted toilet C is fixed by adopting the wall-mounted toilet fixing device, the tail end of the screw 3 'can move in the concave cambered surface 21' of the screw sleeve 2 'only by rotating the screw 3', so that the distance between the wall-mounted toilet and the installation base body is adjusted; however, in order to ensure that the screw 3' is firmly clamped on the concave cambered surface 21', the length of the concave cambered surface 21' cannot be too long, so that the adjustment range of the existing wall-mounted toilet fixing device is small; therefore, the distance between the wall-hung toilet C and the installation matrix W is required to be small enough, and only one locking position can be found by measuring the thickness of the wall-hung toilet C, and the locking position can be matched with the concave cambered surface 21' of the screw sleeve 2' by the screw 3', and the distance between the wall-hung toilet C and the installation matrix W is required to be small enough. In combination, the existing wall-hung toilet bowl fixing device is adopted to fix the wall-hung toilet bowl C, so that the problems of complex operation and small adjusting range exist.

Detailed Description
Embodiment one:
as shown in fig. 3 to 20, the present invention discloses a wall-mounted toilet fixture which is movably matched with a screw S fixed on a mounting substrate W to lock a wall-mounted toilet C on the mounting substrate W, and includes an outer cover 11, an end cover 12, a driven member 2, at least one pressing block 3 movably matched on the driven member 2, a driving member 4 for driving the driven member 2 to rotate and for driving the pressing block 3 to engage the screw S, and a driving member 5 for driving the driving member 4 to rotate.
Specifically, the outer cover 11 and the end cover 12 are detachably matched to form a shell 1 through a fastening structure or a threaded connection structure, and the shell 1 is provided with a first cavity 13 and a second cavity 14 which are intersected and communicated; one end of the first cavity 13 is provided with a through hole 131 penetrating through the housing 1, and two ends of the second cavity 14 are respectively provided with two penetrating holes 141 penetrating through the housing 1 and opposite to each other.
The driven member 2 and the driving member 4 are hollow tubular structures, the driving member 4 and the driven member 2 are rotatably matched in the second cavity 14, the driven member 2 is movably sleeved on the driving member 4, and the driven member 2 is provided with a through hole 21 aligned with the two through holes 141; the side wall of the driven piece 2 is provided with two embedded holes 22 penetrating through the side wall of the driven piece 2, and the two embedded holes 22 are opposite; each embedded hole 22 is movably matched with a pressing block 3, an engagement surface 31 is formed on the inner surface of the pressing block 3 corresponding to the external thread surface of the screw S, the engagement surface 31 can be a straight tooth surface or an inclined tooth surface or an internal thread surface, the engagement relationship between the straight tooth surface, the inclined tooth surface and the internal thread surface and the screw S can be realized, and the engagement degree of the straight tooth surface, the inclined tooth surface, the internal thread surface and the screw S is sequentially increased. The inner wall of the transmission member 4 forms two arc grooves 41 which are concave outwards and respectively correspond to the two embedded holes 22, and in a normal state, the arc grooves 41 are aligned with the embedded holes 22 to form a relief space for the pressing block 3 to move; the side edges of the same side of the two embedded holes 22 are respectively provided with a limiting rib 221 protruding outwards and movably matched in the circular arc groove 41, and the driving piece 4 and the driven piece 2 are movably clamped with each other through the matching of the limiting ribs 221 and the circular arc groove 41 so that the rotation of the driving piece 4 can drive the driven piece 2 to rotate; one end of the driven member 2 protrudes out of the transmission member 4, one end of the driven member 2 protruding out of the transmission member 4 is provided with a stop portion 23 propping against the transmission member 4, and a rotation damping mechanism which enables forward rotation damping and reverse rotation damping of the driven member 2 to exist and enables the reverse rotation damping to be larger than the forward rotation damping is arranged between the stop portion 23 and the second cavity 14. As shown in fig. 4 to 8, when the driving member 4 rotates forward, due to the forward rotation damping of the driven member 2, the driving member 4 rotates forward relative to the driven member 2, so that the limiting ribs 221 of the embedded holes 22 clamp the circular arc grooves 41, so that the driving member 4 has the capability of driving the driven member 2 to rotate forward, and in the process, the inner wall of the driving member 4 pushes the pressing block 3 to move along the radial direction of the driven member 2 towards the direction close to the rotating shaft of the driven member 2, so that the pressing block 3 engages the screw S; after the limiting ribs 221 block the circular arc groove 41, if a larger force is applied to enable the transmission member 4 to continue to rotate in the forward direction, the transmission member 4 drives the driven member 2 and the pressing block 3 to rotate in the forward direction together, and the pressing block 3 is meshed with the screw rod, so that the linear movement of the invention relative to the screw rod S along the axis of the screw rod S is generated by the forward rotation of the pressing block 3. As shown in fig. 4 to 8, if the driving member 4 rotates in the reverse direction after the pressing block 3 engages with the screw S, since the reverse rotation damping of the driven member 2 is greater than the forward rotation damping, the driving member 4 rotates in the reverse direction with respect to the driven member 2 so that the circular arc groove 41 is aligned with the insertion hole 22, and thus the pressing block 3 can move in the relief space formed by the circular arc groove 41 and the insertion hole 22 to be out of engagement with the screw S. It should be noted that, in this embodiment, the two insert holes 22 are not limited to being disposed opposite to each other, and the central axes of the two insert holes 22 may form an included angle of 0 ° to 180 °, so that the press block 3 fitted on the insert holes 22 can also be engaged with the screw S.
As shown in fig. 9 and 10, the stop portion 23 extends away from the rotation axis of the driven member 2 to form two elastic cantilevers 6 with central symmetry, and the distance from the elastic cantilevers 6 to the rotation axis of the driven member 2 increases along the reverse rotation direction of the driven member 2; the inner wall of the second cavity 14 is provided with a plurality of protrusions 7 which are equidistantly distributed and are movably matched with the elastic cantilever 6, the protrusions 7 are of a triangular structure, two sides of each protrusion 7 are respectively provided with a pushing surface 71 and a blocking surface 72 which are movably contacted with the elastic cantilever 6, the distance from the pushing surface 71 to the rotating shaft of the driven member 2 is increased along the forward rotating direction of the driven member 2, and the distance from the blocking surface 72 to the rotating shaft of the driven member 2 is reduced along the forward rotating direction of the driven member 2; the elastic cantilever 6 and the bulge 7 form the rotation damping mechanism; thus, when the driven member 2 rotates positively, the elastic cantilever 6 is pressed by the pushing surface 71 to deform in a direction approaching to the rotating shaft of the driven member 2 so as to pass through the bulge 7, thereby enabling the driven member 2 to have positive rotation damping; when the driven member 2 rotates reversely, the elastic cantilever 6 is abutted by the blocking surface 72 to prevent the driven member 2 from rotating reversely, so that the driven member 2 has reverse rotation damping which is larger than forward rotation damping of the driven member 2. As shown in fig. 11 and 12, the elastic cantilever 6 and the protrusion 7 may be disposed in opposite directions; specifically, the inner wall of the second cavity 14 is provided with two elastic cantilevers 6 that are symmetrical in center, and the distance from the elastic cantilevers 6 to the rotating shaft of the driven member 2 increases along the reverse rotation direction of the driven member 2; the stop part 23 extends to a direction far away from the rotating shaft of the driven member 2 and is formed by a plurality of protrusions 7 which are equidistantly distributed and are movably matched with the elastic cantilever 6, the protrusions 7 are of a triangular structure, two sides of each protrusion 7 are respectively provided with a pushing surface 71 and a blocking surface 72 which are movably contacted with the elastic cantilever 6, the distance from the pushing surface 71 to the rotating shaft of the driven member 2 is reduced along the forward rotating direction of the driven member 2, and the distance from the blocking surface 72 to the rotating shaft of the driven member 3 is increased along the forward rotating direction of the driven member 3; thus, when the driven member 2 rotates positively, the elastic cantilever 6 is pressed by the pushing surface 71 to deform in a direction away from the rotating shaft of the driven member 2 so as to pass through the bulge 7, thereby enabling the driven member 2 to have positive rotation damping; when the driven member 2 rotates reversely, the elastic cantilever 6 is abutted by the blocking surface 72 to prevent the driven member 2 from rotating reversely, so that the driven member 2 has reverse rotation damping which is larger than forward rotation damping of the driven member. As shown in fig. 13 to 16, the elastic cantilever 6 and the protrusion 7 may be provided on the end surface of the stopper 23 and the inner end surface of the second chamber 14; specifically, the end surface of the stop portion 23 extends outwards to form two elastic cantilevers 6 with central symmetry, and the distance from the elastic cantilevers 6 to the end surface of the driven member 2 increases along the reverse rotation direction of the driven member 2; the end surface of the second cavity 14 adjacent to the stop part 23 is provided with a plurality of protrusions 7 which are equidistantly distributed and are movably matched with the elastic cantilever 6, the protrusions 7 are of a triangular structure, two sides of each protrusion 7 are respectively provided with a pushing surface 71 and a blocking surface 72 which are movably contacted with the elastic cantilever 6, the distance from the pushing surface 71 to the end surface of the driven member 2 is increased along the forward rotation direction of the driven member 2, and the distance from the blocking surface 72 to the end surface of the driven member 2 is reduced along the forward rotation direction of the driven member 2; thus, when the driven member 2 rotates positively, the elastic cantilever 6 is pressed by the pushing surface 71 to deform in the direction of approaching the end surface of the stop part 23 so as to pass through the bulge 7, thereby enabling the driven member 2 to have positive rotation damping; when the driven member 2 rotates reversely, the elastic cantilever 6 is abutted by the blocking surface 72 to prevent the driven member 2 from rotating reversely, so that the driven member 2 has reverse rotation damping which is larger than forward rotation damping of the driven member.

In this embodiment, the adjusting cylinder 16 is a hollow cylindrical sleeve structure, and the adjusting cylinder 16 is in threaded connection with the hollow sleeve 15; a limiting stop edge 161 is arranged at one end of the adjusting cylinder 16 far away from the shell 1; specifically, the outer wall of the hollow sleeve 15 may be provided with external threads, and the inner wall of the adjusting cylinder 16 is provided with internal threads matched with the external threads of the hollow sleeve 15; it is also possible that the inner wall of the hollow sleeve 15 is provided with an internal thread, and the outer wall of the adjusting cylinder 16 is provided with an external thread matched with the internal thread of the hollow sleeve 15. Because the hollow sleeve 15 is in threaded connection with the adjusting cylinder 16, the spacing between the spacing baffle edge 161 of the adjusting cylinder 16 and the second cavity 14 can be adjusted by rotating the adjusting cylinder 16, so that the spacing baffle edge 161 and the shell 1 can clamp fixing holes C11 with different lengths to meet the requirements of wall-mounted toilets C with different thicknesses.

In the whole fixing process of the wall-hung toilet C, the thickness of the wall-hung toilet C is not required to be measured to find the locking position, the operation is simple and quick, and the adjustment range of the distance between the wall-hung toilet C and the installation matrix W is wide. After the wall-mounted closestool C is fixed by adopting the invention, if the wall-mounted closestool C is to be detached, the driving piece 5 is driven to reversely rotate by the installation tool, the driving piece 5 drives the driving piece 4 to reversely rotate, at the moment, the driven piece 2 basically does not move due to the action of the rotation damping mechanism, and the driving piece 4 can reversely rotate relative to the driven piece 2, so that the pressing block 3 obtains a yielding space, and the pressing block 3 falls off to engage the screw S, thereby realizing the detachment of the wall-mounted closestool C, and the operation is simple and quick.
In summary, when the wall-mounted closestool C is fixed on the installation substrate W by using the invention, the screw S fixed on the installation substrate W can be directly penetrated in the invention without finding the locking position by measuring the thickness of the wall-mounted closestool C, and the pressing block 3 can be meshed with the screw S to lock the wall-mounted closestool C on the screw by rotating the driving piece 5 positively, so that the operation is simple and quick; when the pressing block 3 is meshed with the screw rod S, the driving piece 5 can be rotated forward to enable the wall-mounted closestool C to move to one side of the installation matrix W, so that the distance between the wall-mounted closestool C and the installation matrix W can be adjusted, and the adjusting range is wide; when the wall-mounted closestool C needs to be detached, the wall-mounted closestool C can be detached simply and quickly by reversely rotating the driving piece 5 to enable the pressing block 3 to be separated from the engagement of the screw S.
