Toilet seat disassembly and assembly mechanism

Abstract

The present invention discloses a disassembly and assembly mechanism for a toilet cover plate, including a bushing which is locked on a toilet seat by bolts. Vertical through mounting holes are symmetrically provided at both ends of the bushing. The bolts pass through the mounting holes from top to bottom to lock with the toilet seat. The mechanism further includes a connecting member disposed within the bushing and capable of axially reciprocating. In the state of the cover plate being disassembled, the whole connecting member retracts into the bushing; in the state of the cover plate being assembled, the end portion on the outer side of the connecting member extends out of the bushing. The mounting holes vertically penetrate the bushing, and the bushing is locked on the toilet seat by bolts. Compared with the way of connecting the bushing to the cover plate, locking the bushing firmly on the toilet seat can firmly lock the bushing, avoid the bushing from shaking, and greatly improve the anti-lateral displacement ability of the cover plate, thus having the advantage of a stable structure. In addition, the quick disassembly and assembly of the cover plate is realized by controlling the telescoping of the connecting member, that is, when the connecting member axially extends, it is inserted into the cover plate, and when the connecting member axially retracts, it is separated from the cover plate, with a simple and reliable structure.

Description

Technical Field

[0001] The invention relates to a disassembly and assembly mechanism for a toilet cover assembly. Background Art

[0002] like Figure 1 As shown, a toilet cover typically includes an upper cover 01 and a seat ring 02. The toilet cover and toilet bowl are quickly connected via a disassembly mechanism. The disassembly mechanism generally includes a connecting shaft 03 and a support 04. Connecting shaft 03 is located in a pivotal portion at the rear end of the upper cover 01 or the seat ring 02. Support 04 is mounted on the toilet bowl and engages with connecting shaft 03 to secure the upper cover 01 and seat ring 02 to the toilet bowl. Support 04 includes a base 04-1 and a latch 04-2. Base 04-1 has an elongated mounting hole for locking bolts, and latch 04-2 is located eccentrically on the base.

[0003] Because the latch and bolt are staggered on the chassis, the latch will rotate around the bolt under the action of external force. That is, the force applied to the toilet cover during use will generate torque at the position of the latch, causing the toilet cover to shake and have poor stability.

[0004] After the toilet seat is installed, the manufacturer must perform a stability test on the seat assembly. This is called a displacement test. This involves applying a set force to the seat and measuring the displacement. Generally, displacement must be within 10mm to qualify. However, the current installation method for toilet seats is not very secure, can only withstand limited impact forces, and is prone to loosening. Summary of the Invention

[0005] The present invention provides a toilet cover disassembly and assembly mechanism with a stable structure. The technical solution adopted by the present invention to solve the technical problem is:

[0006] The toilet cover disassembly and assembly mechanism includes a sleeve, which is locked on the toilet bowl by bolts. The two ends of the sleeve are symmetrically provided with vertically penetrating mounting holes. The bolts pass through the mounting holes from top to bottom to lock with the toilet bowl. The mechanism also includes a connecting piece arranged in the sleeve and capable of axial reciprocating movement; when the cover is removed, the connecting piece is retracted into the sleeve as a whole; when the cover is installed, the outer end of the connecting piece extends out of the sleeve.

[0007] Compared with the background technology, this technical solution has the following advantages:

[0008] The mounting holes vertically penetrate through the bush, and the bush is locked to the toilet seat by bolts. Compared with the way of connecting the bush to the cover plate, locking the bush firmly to the toilet seat can prevent the bush from shaking, greatly improving the anti-lateral displacement ability of the cover plate, thus having the advantage of a stable structure. In addition, quick disassembly and assembly are achieved by controlling the telescoping of the connecting piece, that is, when the connecting piece extends axially, it is inserted into the cover plate, and when the connecting piece retracts axially, it is separated from the cover plate, with a simple and reliable structure.

[0024] Embodiment 1:

[0025] Please refer to Figure 2 and Figure 3 , the toilet cover includes an upper cover 10 and a seat ring 20, and the connecting parts on both sides at the rear end of the upper cover are respectively rotatably connected to the connecting parts on both sides at the rear end of the seat ring. The toilet cover disassembly and assembly mechanism 30 of the present invention is used to connect the toilet cover and the toilet bowl (not shown in the figure), so that the toilet cover can be quickly installed on the toilet bowl or quickly disassembled from the toilet bowl.

[0026] Please refer to Figure 4 and Figure 5 , the disassembly and assembly mechanism 30 includes a bushing 31, the bushing 31 is locked on the toilet bowl 40 by two bolts 32, and vertical through mounting holes 312 are symmetrically provided at both ends of the bushing 31. The mounting holes 312 preferably penetrate vertically in the radial direction, so that the center line of the mounting hole is perpendicular to the center line of the bushing. The bolt 32 passes through the mounting hole 312 from top to bottom and is locked to the toilet bowl 40, thereby locking the bushing 31 on the toilet bowl 40. The disassembly and assembly mechanism 30 further includes two connecting members 33 disposed inside the bushing 31 and capable of axially reciprocating, and the two connecting members 33 are symmetrically located at both ends of the bushing 31. In the locked state, the outer ends of the connecting members 33 extend out of the bushing 31 and then are inserted into the seat ring 20, thereby fixing the toilet cover. If the connecting part of the upper cover 10 is located inside the connecting part of the seat ring 20, the outer ends of the side connecting members 33 are inserted into the upper cover 10.

[0027] Please refer to Figure 6 , in the state of the cover being disassembled, the connecting members 33 are integrally retracted into the bushing 31, and the upper cover 10 and the seat ring 20 can be removed. In this embodiment, the connecting member 33 is an independent component. Of course, the connecting member 33 can also be assembled by multiple components and is an assembly.

[0028] Such as Figure 5 and Figure 6As shown, preferably, two dampers 50 respectively used to control the slow descent of the upper cover 10 and the seat ring 20 are arranged in the connecting parts of the upper cover 10 and the seat ring 20. In this way, the end part outside the connecting piece 33 extends into the upper cover or the seat ring and then is inserted into the damper 50. The dampers 50 on both sides of the toilet cover plate respectively control the slow descent of the upper cover 10 and the seat ring 20. When the cover plate is installed and locked, the two connecting pieces 33 are respectively inserted into the two dampers 50. Of course, it can be that the damper 50 is inserted into the connecting piece 33 as shown in the figure, or the connecting piece 33 is inserted into the damper 50.

[0029] A sink 314 is arranged around the installation hole 312 on the bottom surface of the inner wall of the bushing 31. The head of the bolt 32 is received in the sink 314, that is, the bolt 32 is positioned by using the sink 314, so as to better avoid interference between the bolt 32 and the connecting piece 33.

[0030] Two support seats 316 are symmetrically arranged at the left and right ends of the bottom end of the bushing 31. The two support seats 316 are respectively aligned with the two installation holes 312, and the bolt 32 passes through the support seats 316. The support seats 316 are stably supported on the toilet seat 40. Of course, the bottom surface of the bushing 31 being flattened can also better support on the toilet seat 40. Preferably, the support seats 316 are part of the bushing 31 and are injection-molded together with the bushing 31.

[0031] Please refer to Figure 4 and Figure 5 , the connecting piece 33 is provided with a relief through hole 332 corresponding to the installation hole 312. When the connecting piece 33 extends out of the bushing 31 as a whole and aligns the relief through hole 332 with the installation hole 312, the bolt 32 can pass through the installation hole 312 and the relief through hole 332 of the connecting piece 33 and be locked on the toilet seat 40, which is very convenient for assembly.

[0032] A push-pull rod 334 is arranged on the connecting piece 33. Axially pulling the push-pull rod 334 causes the connecting piece 33 to move axially, so as to control the telescopic movement of the connecting piece 33. Specifically, a slot 318 is arranged on the top surface in the middle of the bushing 31, a gear 34 is arranged in the slot, a row of convex teeth is arranged on the push-pull rod 334, and the convex teeth of the push-pull rod 334 are engaged with the side surface of the gear 34. When the gear 34 rotates, the two connecting pieces 33 can be pulled to make the connecting piece 33 as a whole retract into the bushing 31, or the two connecting pieces can be pushed to make the outer end part of the connecting piece 33 extend out of the bushing 31 and be inserted into the damper 50. The disassembly and assembly mechanism 30 further includes an upper cover 36 for covering the slot 318.

[0033] The disassembly and assembly mechanism 30 further includes a switch 35 for driving the gear 34 to rotate. One end of the switch 35 extends out from the bottom of the bushing 31. During operation, the switch 35 is toggled to drive the gear 34 to rotate. In this way, the switch 35 is located below the bushing, with a hidden function, and the switch 35 cannot be directly seen, which can prevent the cover plate from being maliciously removed when the toilet is used in public. In particular, when the semi-circular decorative cover 37 covers the bushing 31 from above, the switch 35 cannot be seen from the front and rear perspectives and the top-down perspective of the disassembly and assembly mechanism 30, further enhancing the concealment of the disassembly and assembly function. Preferably, the decorative cover 37 is snap-fitted to the bushing 31.

[0034] The disassembly and assembly mechanism 30 further includes a compression spring 38 tensioned between the upper cover 36 and the gear 34 and a return spring 39 tensioned between the connecting member 33 and the bushing 31. The compression spring 38 presses on the gear 34, which can ensure that the engagement between the gear 34 and the convex teeth of the push rod 334 is smoother. Lock tongues 317 are respectively provided on both sides of the gear 34 in the slot 318. The lock tongues 317 are inserted into the gear 34 to prevent the switch 35 from driving the gear 34 to rotate. When operation is required, the switch 35 is pressed, and the gear 34 overcomes the elastic force of the compression spring 38 and moves upward. After the gear 34 is separated from the lock tongue 317, the switch 35 is toggled again. In this way, it can be ensured that during normal use, the connecting member 33 will not retreat under the action of an external force against the force of the return spring 39. The return spring 39 is used to generate an axially outward driving force, aiming to push the outer end of the connecting member 33 out of the bushing 31. In this way, the connecting member 33 is driven by the return spring 39 to be inserted into the damper 50 during the use state. When disassembly and assembly are required, the switch 35 overcomes the elastic force of the return spring 39 to rotate the gear 34, making it more simple to use.

[0035] It can be understood that as long as the connecting member 33 can freely retract into the bushing 31, the upper cover and the seat ring can be removed, and when the outer end of the connecting member 33 extends out of the bushing 31, it can be inserted into the upper cover and the seat ring. Therefore, the return spring 39 can be used to push out the connecting member 33. When disassembly and assembly are required, the connecting member 33 is manually pulled, and the whole connecting member 33 is pulled inward into the bushing 31 until the whole connecting member 33 retracts into the bushing 31.

[0036] In addition, the disassembly and assembly mechanism can also be provided with a connecting member 33 only on one side of the bushing 31, and a plug-in terminal is provided on the other side of the bushing 31 to be directly plugged into the upper cover or the seat ring. In this way, during the installation process, the connecting member 33 is first retracted into the bushing, and then the bushing is tilted and placed. First, the plug-in terminal on the other side of the bushing is plugged into the upper cover or the seat ring, then the bushing is laid flat, and finally the connecting member 33 extends out and is plugged into the upper cover or the seat ring. That is to say, a connecting member 33 can be provided only on one side of the bushing 31, and a single connecting member 33 can also achieve quick disassembly.

[0037] Embodiment 2:

[0038] Please refer to Figure 7 and Figure 8 , the differences between the second embodiment and the first embodiment are as follows: First, the connecting member 33 is not an independent component, but a combination, including a damper 33-1 and a bushing 33-2 that sleeves the damper. The damper 33-1 is arranged in the sleeve 31. A push-pull rod 334 is provided on the bushing 33-2. Axially pulling the push-pull rod 334 causes the connecting member 33 to move axially. If a push-pull rod 334 is directly provided on the damper 33-1, the bushing 33-2 can be omitted; Second, a driving gear 352 is sleeved on the switch 35. The driving gear 352 is in meshing transmission with the gear 34. The gear 34 corresponds to the push-pull rod 334 one by one. When in use, the switch 35 is toggled, and the driving gear 352 rotates together, driving the gear 34 to rotate, causing the push-pull rod 334 to move; Third, the driving gear 352 presses on the gear 34, and the upper cover 36 further covers the driving gear 352. When installing or disassembling, the connecting member 33 contracts inward to make way for the bolt 32, and the bolt 32 can be installed or disassembled through the installation hole 312.

[0039] In this solution, the damper 33-1 is arranged in the sleeve 31, which can greatly simplify the structure of the toilet cover. It not only has the slow-falling function, but also directly uses the damper 33-1 to be inserted into the toilet cover, with a simple structure (making the overall width of the cover tail smaller, so as to adapt to more toilet shapes).

[0040] The third embodiment:

[0041] Please refer to Figure 9 and Figure 10 , the differences between the third embodiment and the second embodiment are as follows: First, the connecting member 33 further includes a connecting shaft 33-3. The connecting shaft 33-3 is axially inserted into the damper 33-1. When the cover is in the installed and locked state, the end of the connecting shaft 33-3 extends out of the sleeve 31. The connecting shaft 33-3 is provided with a relief through hole 332 corresponding to the installation hole 312; Second, the switch 35 drives the gear 34 to rotate, the gear 34 drives the push-pull rod 334 to move, and the upper cover 36 covers the gear 34; Third, the installation hole 312 penetrates downward through the support base 316. A spacer 311 is screwed inside the support base 316. The bolt 32 passes through the spacer 311, and the head of the bolt presses on the spacer.

[0042] In this solution, the connecting piece 33 is provided with a connecting shaft 33-3. Since the connecting shaft 33-3 is provided with a relief through-hole 332, when the connecting piece 33 is moved until its relief through-hole 332 is aligned with the mounting hole 312 and the bolt 32, the bolt 32 can be disassembled and assembled. The moving stroke of the connecting piece 33 is small and the operation is more stable. In addition, the mounting hole 312 penetrates downward through the support seat 316, which can simplify the structure of the bushing 31 and is easy to injection mold. Understandably, the connecting shaft 33-3, the damper 33-1, and the toilet cover rotate together. It can be set that when the toilet cover is opened to the vertical state, the relief through-hole 332 is aligned with the mounting hole 312 and the bolt 32.

[0043] Embodiment 4:

[0044] Please refer to Figure 11 and Figure 14 , the difference between Embodiment 4 and Embodiment 3 is as follows: First, a pair of mating helical surfaces 341 and 351 are provided between the switch 35 and the gear 34. The gear 34 is restricted from moving vertically. After the switch 35 is pressed inward, the gear 34 can be driven to rotate through the transmission of the helical surfaces 341 and 351. Second, a gasket 313 is provided in the mounting hole 312. The gasket 313 is rotatably supported on the plane of the sink 314. The gasket 313 is provided with a long hole 315. The bolt 32 passes through the long hole 315 of the gasket, and the head of the bolt presses on the gasket. When the gasket 313 is rotated, the bolt 32 can be driven to move together, so that the bolt 32 can be locked within the range covered by the long hole 315, which can adapt to more models of toilet seats. Of course, as long as the bolt 32 can move in the mounting hole 312, the position of the bolt 32 can be adjusted. For example, if the part of the mounting hole 312 passing through the support seat 316 is a long hole, the bolt 32 will have room to move.

[0045] The above is only a preferred embodiment of the present invention, so the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
