Description

Quick-dismantling installation connection assembly of cover plate and ceramic body for closestool

Technical Field

The invention relates to the field of toilets, in particular to a quick-dismantling installation and connection assembly of a cover plate and a ceramic body for a toilet.

Background

At present, a part of toilets (also called toilets) on the market are fixed in a buckling mode between a cover plate and a ceramic body, and due to gaps among all parts of the buckles, looseness between a base and the ceramic body is easily caused, and after a person sits, the toilet cover can slightly shift, so that comfort level of user experience is affected. Some are fixed by forced fastening and forced tripping, which is difficult in terms of disassembly and maintenance, and the fastening is easy to break after being disassembled by forced tripping for many times, so that the fastening function is invalid. The screw fixing mode is adopted, when the tool is required to be used for disassembling, the disassembling position is set to be relatively back, the tool is attached to the wall after being installed, the tool is difficult to normally use, and the tool is inconvenient to disassemble or store after-sale maintenance service.

Disclosure of Invention

The invention aims to solve the problems and the defects, and provides a quick-dismantling and installing and connecting assembly of a closestool cover plate and a ceramic body, which can enable the cover plate to be tightly matched and fixed with the ceramic body, and can unlock a main locking seat to easily pull up the whole closestool cover plate only through a simple outward pulling action when the closestool cover plate is dismantled, and is particularly convenient for disassembly and after-sale maintenance service. Meanwhile, the setting position of the device is hidden, the appearance of the whole product is not directly influenced, and the disassembly is convenient.

The technical scheme of the invention is realized as follows:

the invention relates to a quick-dismantling installation connection assembly of a cover plate and a ceramic body for a closestool, which is characterized in that: the novel ceramic lock comprises a main locking seat, at least one auxiliary fixing seat and a inhaul cable type switch assembly, wherein the main locking seat can lock a cover plate base and a ceramic body together, the inhaul cable type switch assembly is arranged at the rear part of the ceramic body, and the switch assembly is connected with the main locking seat through a Williams (also called a brake cable, a pull wire and the like) and controls the locking and the opening of the main locking seat.

The invention is also characterized in that the main locking seat is locked by the unidirectional air valve component, and the invention has simple structure and simple operation.

An embodiment of the present invention is described in detail below with reference to the attached drawings:

1) Before the cover plate 1 is assembled, the push rod 32' and the fixing column 41 are respectively locked on the cover plate base 1 by self-tapping screws. The piston 321 'is sleeved on the push rod 32', and the piston 321 'is blocked by a boss on the push rod 32' to prevent the piston from falling off. An O-ring 42 is fitted into the groove of the fixing column 41.

2) The sealing rubber head 35 ' is sleeved on a boss 361 ' of the ejector rod 36 ', the wire head 61 of the Willia wire 6 passes through the ejector rod return spring 37 ' and is sleeved in a connecting groove 362 ' of the ejector rod 36 ', and the wire head is fixed on the piston cylinder 31 ' by a wire buckle 34 ', and the wire head is prevented from falling off by virtue of the boss 361 '. Under the action of the ejector rod reset spring 37 ', the ejector rod 36 ' drives the sealing rubber head to cling to the air outlet hole at the bottom of the piston cylinder 31 ', so that the sealing rubber head forms a one-way air valve: the air can only be discharged and can not be fed.

3) After the fixing sleeve 43 and the piston cylinder 31 'of the fixing column are respectively sleeved with gaskets and pass through corresponding mounting holes of the ceramic body 2, the fixing sleeve is respectively locked by a locking nut 33' and a locking nut 45.

4) The pull rod 51 is sleeved with a return spring 53 and passes through a switch shell 54, the two are fixed in the switch shell 52 by a gland 52, the assembled switch assembly 5 transversely passes through another mounting hole on the rear part of the ceramic body 2 and is locked by a locking nut 56, the other wire end 62 of the Williams 6 is sleeved in a connecting groove 511 of the pull rod 51, and then the Williams 6 are fastened by a switch wire buckle 55.

5) When the cover plate base 1 is installed, the push rod 32 'is aligned with the inner cavity of the piston cylinder 31' and the fixing column 41 is aligned with the inner cavity of the fixing sleeve 43 to be directly inserted. When the cover plate base 1 is mounted in place, air is completely discharged from the exhaust hole at the bottom of the piston cylinder 31 'due to the sealing effect of the piston 321', so that the inner cavity of the piston cylinder forms vacuum, and at the moment, the cover plate base 1 of the cover plate cannot be directly pulled out. The structure is used for realizing the purpose of fixedly connecting the cover plate base 1 and the ceramic body 2 by the unidirectional air valve and by utilizing the atmospheric pressure principle. To pull out the cover plate, only the pull rod 51 is pulled outward and turned slightly, the locking protrusion 512 on the pull rod 51 can make the switch assembly 5 be in an opened state (the locking protrusion slides out of the chute and is matched with the locking limit boss to be arranged in a top position), so that the pull rod 51 is positioned and locked, and at the moment, the cover plate and the cover plate base 1 can be normally taken down. After the cover plate is taken down, the pull rod 51 is slightly rotated by an angle (the top of the locking limiting boss is released to the clamping boss), the pull rod 51 is reset under the action of the pull rod reset spring 53, meanwhile, the ejector rod 36 ' pushes the sealing rubber head 35 ' to reset under the action of the ejector rod reset spring 37 ', and the one-way air valve function is restored, so that necessary conditions are provided for the next installation and fixation.

The main characteristic of the structure is that the pull rod 51 is connected with the ejector rod 36' through the Williams 6, and the opening and closing of the unidirectional air valve is controlled through the pull rod 51; the purpose of the fixed connection of the cover plate base 1 and the ceramic body 2 is realized by a unidirectional air valve and by utilizing the atmospheric pressure principle.

Although the invention has been described with reference to specific embodiments, this description is not meant to limit the invention. Other variations to the disclosed embodiments can be envisioned by those skilled in the art with reference to the description of the invention, and such variations are intended to fall within the scope of the appended claims.
