Description

Technical Field

[0001] The invention relates to a quick disassembly and assembly mechanism of a toilet cover plate, which realizes quick disassembly and assembly between the toilet cover plate and the toilet. Background Art

[0002] The toilet cover and the toilet bowl are quickly connected through a quick-folding structure, which makes the toilet cover detachable. Currently, most quick-folding structures are operated by button unlocking. The button is installed on the toilet cover and the support rod is installed on the toilet bowl. Under normal circumstances, the lock hole on the button is buckled with the slot of the support rod to lock the toilet cover. When disassembly is required, press the button to separate the lock hole from the slot.

[0003] The Chinese utility model patent with authorization announcement number CN209421821U discloses in detail a quick-release structure of a toilet cover, including a cylindrical body, a pillar, a locking component, and an elastic component. The locking component includes a button, a locking plate and a hook. The pillar is inserted into the column hole on the body, and the locking plate is clamped with the pillar. The body is also provided with a locking plate movement hole and a hook movement hole. When unlocking, the button is pressed, the locking plate is separated from the pillar, and the hook hooks the body to maintain the unlocked state. When the toilet cover is removed, the pillar pushes the hook open, and the locking plate is reset under the action of the spring.

[0004] However, in actual use, it was found that the location of the buttons easily hides dirt, or consumers have psychological reservations and are very reluctant to press the buttons directly with their fingers. Summary of the invention

[0005] The present invention provides a quick disassembly and assembly mechanism for a toilet cover, which overcomes the shortcomings of the background technology. The technical solution adopted by the present invention to solve the technical problem is:

[0006] The quick disassembly and assembly mechanism of the toilet cover comprises a fixed shaft, a spring, and a button. The spring is tensioned between the fixed shaft and the button. The button can reciprocate axially. A locking piece and a hook are arranged on one side of the button. The end surface of the fixed shaft is axially extended inward to set a mounting hole. The pusher is also included. The button and the pusher are sequentially installed in the mounting hole. The pusher can be reciprocated vertically in the mounting hole. When the pusher moves downward, it drives the button to move axially to achieve unlocking. The transmission device that drives the pusher to move vertically is also included. The invention relates to a member and a limiting sleeve sleeved on the transmission member, one end of the transmission member extends into the mounting hole and is connected to the pushing member, the end of the limiting sleeve is plugged into the fixed shaft and the two can rotate relative to each other, one of the limiting sleeve and the fixed shaft is provided with a limiting block and the other is provided with a giving opening, the limiting block and the giving opening can be plugged into each other, when locked, the limiting block and the giving opening are misaligned so that the limiting block prevents the transmission member from moving vertically downward, and when unlocked, the giving opening is aligned with the limiting block so that the transmission member can drive the pushing member to move vertically downward.

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

[0008] The button is directly received in the mounting hole of the fixed shaft. When unlocking, the stop sleeve is rotated to align the clearance opening with the stop block, so that the transmission member can drive the push member to move downward. Because the push member drives the connection button, the button is driven to move axially and horizontally to unlock at the same time. With the help of the vertical movement of the push member, the button can be driven to move axially to reach the unlocking position. Due to the use of hidden buttons, the unlocking operation does not require directly pressing the button, which caters to the needs of consumers and improves practical performance.

[0018] Please refer to Figure 1 The toilet cover 10 includes an upper cover 12 and a seat ring 14. The quick disassembly mechanism of the present invention is used to lock the toilet cover 10 with the pillar 20 on the toilet bowl. Since there are two pillars 20, a pair of quick disassembly mechanisms A and B are used during installation, which are separately arranged on the left and right. The quick disassembly mechanism A and the quick disassembly mechanism B have similar structures, and the quick disassembly mechanism A is mainly introduced below.

[0019] Please refer to Figures 1 to 8The quick disassembly mechanism A includes a fixed shaft 30, a spring 40, and a button 50. The spring 40 is tensioned between the fixed shaft 30 and the button 50. The button 50 can reciprocate axially. A locking piece 52 and a hook 54 are provided on one side of the button 50. A radial hole is provided on the fixed shaft 30 for the pillar 20 to be inserted. When locking, the elastic force of the spring 40 drives the locking piece 52 to fasten the pillar 20. When unlocking is required, the button 50 overcomes the elastic force of the spring 40 and moves axially, so that the locking piece 52 releases the pillar 20. At the same time, the hook 54 will hook the positioning structure of the fixed shaft 30. When the pillar 20 is moved out, the pillar 20 will push open the hook 54. Finally, the button 50 is reset under the drive of the spring 40. The locking and unlocking principle of the button 50 is actually the prior art, and the difference of the present invention is that: the end surface of the fixed shaft 30 is provided with a mounting hole 32 extending inward along the axial direction, and the quick disassembly and assembly mechanism A also includes a pusher 60, a transmission member 70 and a limit sleeve 80. The button 50 and the pusher 60 are sequentially installed in the mounting hole 32, and the pusher 60 can be vertically reciprocated and arranged in the mounting hole 32. The other side of the button 50 is provided with a pressure inclined surface 56, and the pusher 60 is provided with a pressure inclined surface 62 pressed against the pressure inclined surface. The transmission member 70 is used to drive the pusher 60 to move vertically in the mounting hole 32, and one end of the transmission member 70 extends into the mounting hole 32 and is connected to the pusher 60. The limiting sleeve 80 is sleeved on the transmission member 70, and its end is plugged into the fixed shaft 30 and the two can rotate relative to each other, that is, the limiting sleeve 80 can rotate, the limiting sleeve 80 is provided with a clearance opening 82, and the fixed shaft 30 is provided with a limiting block 34, and the limiting block 34 and the clearance opening 82 can be plugged into each other. When locked (the seat ring is in normal use), Figure 7 As shown, the stop block 34 is misaligned with the clearance opening 82 so that the stop block 34 prevents the transmission member 70 from moving vertically downward, so that the push member 60 cannot push the button 50. When unlocked (the seat ring is opened 90 degrees), as shown in FIG. Figure 8As shown, the limiting sleeve 80 rotates until its clearance opening 82 is aligned with the limiting block 34, so that the transmission member 70 can drive the push member 60 to move vertically downward. While the push member 60 moves vertically downward, the button 50 is pushed to move axially to the unlocking position through the transmission of the pressure-applying inclined surface 62 and the pressure-receiving inclined surface 56. Of course, the positions of the limiting block 34 and the clearance opening 82 can also be swapped, as long as the two can prevent the limiting sleeve 80 from moving downward when they are staggered. In addition, other transmission methods can be used between the pushing member 60 and the button 50 to realize that the pushing member 60 drives the button 50 to move horizontally for unlocking. For example, a transmission method of gears and gears can be set between the two. The pushing member 60 first drives the first rack to move vertically, drives the gear to rotate through the first rack, and then drives the second rack to move horizontally by the gear. Or the pushing member 60 and the button 50 adopt a pneumatic transmission method. After the pushing member 60 moves downward, it squeezes the airbag, and after the air pressure increases, it pushes the button 50 to move horizontally. In short, the push member 60 and the button 50 can be connected by a ramp transmission connection, a gear rack transmission connection, or an airbag transmission connection.

[0020] The limiting sleeve 80 is linked with the toilet cover 10, and the toilet cover 10 drives the limiting sleeve 80 to rotate, that is, the rotation of the limiting sleeve 80 is controlled by the flipping of the toilet cover 10, which is more convenient to use. Similarly, the transmission member 70 is linked with the toilet cover 10, and the toilet cover 10 drives the transmission member 70 to move vertically, that is, the unlocking operation is to press the toilet cover 10 vertically downward, and when the toilet cover 10 moves downward, the transmission member 70, the limiting sleeve 80 and the pushing member 60 are driven to move downward synchronously. Therefore, the unlocking operation is to flip the toilet cover 10 and press the toilet cover 10 downward, which is very convenient to use.

[0021] Specifically, the limiting sleeve 80 is linked with the seat ring 14, and the seat ring 14 turns over while driving the limiting sleeve 80 to rotate. When the seat ring 14 is opened to a substantially vertical state, the clearance opening 82 is aligned with the limiting block 34. In this way, it can prevent the locking by mistake when only the upper cover 12 is opened, and it can also prevent the seat ring 14 from being locked by mistake when in use, and ensure the stability of the seat ring when in normal use.

[0022] A connecting sleeve 142 is provided at the rear side of the seat ring 14, and the end of the limiting sleeve 80 is inserted into the connecting sleeve 142 and circumferentially engaged with the connecting sleeve 142, so that when the seat ring 14 is turned over, the limiting sleeve 80 will be driven to rotate, and the structure is simple.

[0023] Preferably, the transmission member 70 is a damper, and the core shaft of the damper 70 is plugged with the pusher 60. A connecting sleeve 122 is provided on the rear side of the upper cover 12, and the transmission member 70 is connected in series with the connecting sleeve 122 of the upper cover and the connecting sleeve 142 of the seat ring. When the upper cover 12 is opened, the connecting sleeve 122 of the upper cover 12 drives the outer shell of the transmission member 70 to rotate, so that the transmission member 70 can also bring a damping effect to the upper cover.

[0024] Preferably, the quick disassembly mechanism A further comprises a shaft sleeve 90 , in which the fixed shaft 30 is accommodated, and in which the rest of the limiting sleeve 80 is accommodated.

[0025] Preferably, the end surface of the fixed shaft 30 is provided with a pivot groove 36 around the mounting hole, one end of the limiting sleeve 80 is rotatably inserted into the pivot groove 36, and the limiting block 34 is arranged at the bottom of the pivot groove 36. When locked, the limiting block 34 presses against the limiting sleeve 80 to prevent the transmission member 70 from moving vertically downward, and when unlocked, the limiting sleeve 80 rotates until its clearance opening 82 is aligned with the limiting block 34. Preferably, a limiting ring 84 is provided on the end surface of the limiting sleeve 80 in a C shape, the clearance opening 82 is arranged on the limiting ring 84, and the limiting ring 84 is rotatably inserted into the pivot groove 36.

[0026] The quick disassembly and assembly mechanism B also includes a fixed shaft 30, a spring 40, a button 50, a pusher 60, a transmission member 70, a limiting sleeve 80, and a shaft sleeve 90. The quick disassembly and assembly mechanisms A and B share a shaft sleeve 90. The difference between the quick disassembly and assembly mechanism B and the quick disassembly and assembly mechanism A is that: the transmission member 70 passes through the connecting sleeve 142 and is circumferentially clamped with the connecting sleeve 142, and the limiting sleeve 80 is circumferentially clamped with the transmission member 70. The limiting sleeve 80 is accommodated in the shaft sleeve as a whole, that is, when the seat ring 14 is flipped, the outer shell of the transmission member 70 is driven to rotate, which brings a damping effect to the seat ring 14, and when the outer shell of the transmission member 70 rotates, it drives the limiting sleeve 80 to rotate.

[0027] Therefore, combined with Figure 1 and Figure 6 When the upper cover 12 is opened, the outer shell of the transmission member 70 of the quick disassembly mechanism A rotates. When the seat ring 14 is opened, the connecting sleeve 142 of the seat ring 14 drives the limiting sleeve 80 of the quick disassembly mechanism A to rotate, and at the same time drives the outer shell of the transmission member 70 of the quick disassembly mechanism B to rotate. The transmission member 70 of the quick disassembly mechanism B then drives its limiting sleeve 80 to rotate.

[0028] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
