Description

Technical fields:

[0001] This utility model belongs to the field of toilet seat installation, specifically related to a quick-release device for toilet seats. Background technology:

[0002] Existing toilet seats require removal for routine cleaning and maintenance. Some existing toilet seats require pressing two buttons on the left and right, or holding the buttons down with one hand while removing the seat with the other, which is inconvenient. For example, Chinese patent CN202123256847.0 discloses a quick-release device for toilet seats, which involves pressing a button with one hand and removing the seat with the other. During assembly, the buckle locks into the groove. Although this solution allows for a lighter force, one hand must hold down the button to remove the seat, which is inconvenient. Moreover, most existing technologies rely on plastic deformation to hook the latch, which is quite strenuous. Utility model content:

[0003] To address the aforementioned problems in the prior art, the present invention aims to provide a quick-release device for toilet seats that is simple in structure and easy to install and operate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The toilet seat quick-release device includes a seat assembly and a mounting bracket assembly that cooperate with each other. The mounting bracket assembly is fixed to the toilet seat and has slides on both sides. The seat assembly has grooves on both sides that cooperate with the slides. The seat assembly is installed or removed by the quick-release device in conjunction with the mounting bracket assembly. The quick-release device includes a button assembly and a retaining plate assembly that cooperate with each other. The button assembly includes a button and a return spring. The button is mounted on the base of the seat assembly, and an elastic element is installed between the base and the button to ensure that the button is held in the initial position. A boss is formed at the front end of the button, and the inner sides of the boss are chamfered. The retaining plate assembly includes a mounting seat, a retaining plate, and an elastic element that cooperate with each other. The mounting seat is formed on the mounting plate of the mounting bracket assembly, and the outer side of the mounting seat is shaped like a retaining plate. The hook has a chamfered edge on its outer side. A retainer is spring-loaded and movable within the mounting base via an elastic element. The elastic element is installed between the retainer and the mounting base. A hook is formed at the top of the outer end of the retainer, with its initial height higher than the bottom surface of the button boss. A chamfered edge is formed on the outer side of the hook. When the chamfered edge of the mounting base touches the chamfered edge of the button, the button is pulled in the pressing direction until the button boss passes the chamfered edge of the mounting base. The boss then touches the chamfered edge of the retainer, causing the retainer to move away from the boss and release the hook position. The boss slides into the hook position and is fixed in place. When the button is pressed, the button boss disengages from the hook position. Under the action of the elastic element, the retainer returns to the upper part of the hook position, ensuring that the boss is locked against the side of the retainer, thus disengaging the boss from the hook and removing the cover assembly.

[0006] Furthermore, the side of the button boss forms a slope one, and the inner side forms a slope two; the inner side of the hook forms a slope three; one side of the hook forms a slope four; when the cover plate assembly and the mounting bracket assembly are locked, slope one hooks the slope three of the hook to ensure that the cover plate assembly cannot be dislodged from the mounting bracket assembly; when the cover plate assembly and the mounting bracket assembly are unlocked, slope two hooks the slope four of the hook to ensure that the button is fixed in the unlocked state.

[0007] Furthermore, a limiting block is provided on the side of the baffle, and an empty groove is provided on the mounting base at the position where the limiting block mates. When the baffle is connected to the mounting base, it ensures that the limiting block extends into the receiving groove for limitation.

[0008] Furthermore, the elastic element is a spring or a sheet.

[0009] Furthermore, the base has a hollow groove on the side, into which the button slides.

[0010] Furthermore, the elastic body is a return spring.

[0011] Furthermore, the baffle is hinged to the inside of the mounting base.

[0012] Using the above technical solution, this utility model employs a button, a baffle, and a mounting base in conjunction. During installation, the sliding groove of the cover plate assembly aligns with the sliding groove of the mounting bracket and slides to the bottom. A return spring is provided between the button and the base to keep the button in its initial position. During installation, the button's protrusion slides into the hook position of the mounting base to complete the installation. When disassembling the cover plate assembly, pressing the button disengages the button protrusion from the hook position and locks it against the side of the baffle, thus disengaging the protrusion from the hook. At this point, the cover plate assembly can be removed. The structure is simple, and the installation and operation are convenient. Especially during disassembly, only the button needs to be pressed; there is no need to hold the button down continuously, allowing for flexible operation. Furthermore, the combination of several chamfers and bevels, along with the assistance of elastic components, allows for a lighter pressing force and a better feel. Attached image description:

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0026] Figures 1-11 The image shown is an embodiment of this utility model.

[0027] The toilet seat quick-release device includes a seat assembly 1 and a mounting bracket assembly 2 that cooperate with each other. The mounting bracket assembly 2 is fixed to the toilet seat and has slides 21 on both sides. The seat assembly 1 has slide grooves 11 on both sides that cooperate with the slides 21. The seat assembly 1 is installed or removed by the quick-release device 3 in conjunction with the mounting bracket assembly 2. The quick-release device 3 includes a button assembly 31 and a baffle assembly 32 that cooperate with each other. The button assembly 31 includes a button 311 and an elastic body (in this embodiment, a return spring 312). The button 31 is installed... On the base 12 of the cover plate assembly 1, a return spring 312 is installed between the base 12 and the button 311 to ensure that the button remains in the initial position. A boss 3111 is formed at the front end of the button 3111, and chamfers 3112 are formed on both sides of the inner side of the boss 3111. The baffle assembly 32 includes a mounting base 321, a baffle 322, and an elastic element 323 that cooperate with each other. The mounting base 321 is formed on the mounting plate 22 of the mounting bracket assembly 2. A hook 3211 is formed on the outer side of the mounting base 321, and chamfers 3212 are formed on the outer side of the hook 3211. 322 is hinged to the inside of the mounting base 321 (or can be a vertically sliding structure). An elastic element 323 is installed between the baffle 322 and the mounting base 321. A hook 3221 is formed at the top of the outer end of the baffle 322, and the initial height of the hook 3221 is higher than the height of the bottom surface of the button boss 3111. A chamfer 3222 is formed on the outer side of the hook. When the chamfer 3222 of the mounting base 321 contacts the chamfer 3112 of the button 311, the button 311 is pulled in the pressing direction until the button boss 3111 passes the chamfer 3112 of the mounting base 321. At position 3212, the boss 3111 touches the chamfer 3222 of the baffle 322, causing the baffle 322 to move away from the boss, thus freeing up the position of the hook 3211. The boss 3111 slides into the position of the hook 3212 and is fixedly installed. Pressing the button 311 causes the boss 3111 to disengage from the position of the hook 3212. Under the action of the elastic element 323, the baffle 322 returns to the upper part of the position of the hook 3212, ensuring that the boss 3111 is locked on the side of the baffle 322, thereby disengaging the boss 3111 from the hook 3212 and removing the cover plate assembly 1.

[0028] In a specific embodiment, the side of the button 311 protrusion 3111 forms a first slope 3113, and the inner side forms a second slope 3114; the inner side of the hook 3211 forms a third slope 3213; one side of the protrusion 3221 forms a fourth slope 3222; when the cover plate assembly 1 and the mounting bracket assembly 2 are locked, the first slope 3113 hooks the third slope 3213 of the hook 3211 to ensure that the cover plate assembly 1 cannot be dislodged from the mounting bracket assembly 2; when the cover plate assembly 1 and the mounting bracket assembly 2 are unlocked, the second slope 3114 hooks the fourth slope 3223 of the protrusion 3221 to ensure that the button is fixed in the unlocked state.

[0029] Furthermore, a limiting block 3224 is provided on the side of the baffle 322, and an empty groove 3214 is provided on the mounting base 321 at the position where it mates with the limiting block 3224. When the baffle 322 is connected to the mounting base 321, the limiting block 3224 is ensured to extend into the receiving groove 3214 for limitation.

[0030] Furthermore, the elastic element 323 is a spring or a sheet spring.

[0031] Furthermore, the base 11 has a hollow channel 111 on its side, and the button 31 extends into the hollow channel 111 and slides.

[0032] During installation, the cover plate assembly's groove aligns with the mounting bracket's groove and slides to the bottom. A return spring is installed between the button and the base to keep the button in its initial position. During installation, when the chamfer of the mounting base touches the chamfer of the button, the button is pulled in the pressing direction until the button boss passes the chamfer of the mounting bracket and touches the chamfer of the retaining plate. This causes the retaining plate to move away from the boss, creating space for the latch, and the boss slides into the latch position, completing the installation. To remove the cover plate assembly, press the button. The button boss disengages from the latch position, and the retaining plate, under the action of the elastic element, springs back to the upper part of the latch position, causing the boss to lock onto the side of the retaining plate, thus disengaging the boss from the latch. At this point, the cover plate assembly can be removed.

[0033] The button has two bevels at its end, bevel one and bevel two. When the cover plate assembly and the mounting bracket assembly are locked, bevel one hooks onto bevel three of the mounting bracket, preventing the cover plate assembly from detaching from the mounting bracket assembly. Furthermore, the more force is applied to the cover plate, the more securely the cover plate assembly and the mounting bracket assembly are joined. When the cover plate assembly and the mounting bracket assembly are unlocked, bevel two hooks onto bevel four of the baffle, fixing the button in the unlocked state. The cover plate assembly can detach from the mounting bracket assembly without the need for the button to be held down continuously.

[0034] This utility model uses a button, a baffle, and a mounting base in combination, resulting in a simple structure and convenient installation and operation. Especially during disassembly, simply pressing the button eliminates the need to hold it down, allowing for flexible operation. Furthermore, the combination of several chamfers and bevels, along with the assistance of elastic components, allows for lighter pressing force and a better feel.

[0035] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
