Description

Technical Field

[0001] This utility model relates to the field of toilet seat technology, specifically a convenient replaceable and detachable toilet seat ring. Background Technology

[0002] As living standards improve, users are increasingly demanding greater convenience and maintenance efficiency from bathroom products. Toilet seats, being frequently used components, require quick installation and removal, making this a key area of ​​research and development. Currently, toilet seats are mostly connected to the toilet surface using traditional snap-fit ​​or bolt methods. Some improvements have introduced elastic elements or knob control structures, but these generally suffer from cumbersome operation procedures, high installation precision requirements, and a tendency to loosen over time.

[0003] Publication No. CN221060534U discloses a quick-release structure for a toilet seat and toilet bowl, comprising a fixed shaft, a quick-release assembly, and a spring-loaded component. The seat and toilet bowl are pivotally connected to the quick-release assembly. The fixed shaft is used to fix and extend onto the toilet bowl, and a first groove is formed in the recessed side wall of the fixed shaft. A snap-fit ​​component is slidably disposed on the quick-release assembly, and it has a fixed shaft insertion hole and a threaded hole. The fixed shaft insertion hole is used for insertion of the fixed shaft, and a pusher is screwed into the threaded hole. The pusher engages with the snap-fit ​​component at an angle, so that when the pusher rotates inward, it pushes the snap-fit ​​component radially into the fixed shaft insertion hole and inserts it into the first groove on the side wall of the fixed shaft, thereby limiting the fixed shaft from exiting the fixed shaft insertion hole. The spring-loaded component is disposed between the snap-fit ​​component and the quick-release assembly, and is used to elastically push the snap-fit ​​component out of the fixed shaft insertion hole. This device can prevent users from accidentally pressing the button to remove the toilet seat and toilet bowl, and it can also achieve quick release. However, this patent still has the following problems in actual use:

[0004] The aforementioned device requires not only threaded holes but also elastic plates. Disassembly requires additional tools or knobs, making one-handed, one-button operation impossible. The elastic plates are prone to fatigue under long-term stress, leading to loosening of the locking mechanism and causing the toilet seat to wobble.

[0005] A convenient and replaceable detachable toilet seat is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a convenient replaceable and detachable toilet seat to solve the problems mentioned in the background art, which not only require the use of threaded holes but also elastic plates. Disassembly requires additional tools or knobs, making one-handed one-button operation impossible. The elastic plates are prone to fatigue under long-term stress, leading to loosening of the locking mechanism and easy shaking of the toilet seat.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a convenient replaceable and detachable toilet seat, comprising a toilet seat body and a toilet surface on which the toilet seat body is installed, wherein the toilet seat body includes a seat cushion and a cover.

[0008] The back of the seat cushion is provided with a quick-release assembly, which includes an installation block. The installation block rotates symmetrically on the back of the seat cushion. A vertical plate is symmetrically and fixedly connected to the top surface of the installation block. A rotating shaft is fixedly connected between the vertical plates. A pressing round block is rotatably sleeved on the outside of the rotating shaft. An insert is fixedly connected to the bottom surface of the installation block. A vertical cone slides vertically through the middle of the installation block.

[0009] The bottom surface of the insert is fixedly connected to a plastic cover, the plastic cover has four split grooves on its outside, and extrusion balls are fixedly embedded in both the outer and inner walls of the plastic cover.

[0010] The toilet seat has a pair of grooves on its top surface and a positioning cylinder fixedly connected to its bottom surface.

[0011] Preferably, the rotating shaft is eccentrically fixedly connected to the extrusion block, a crank is fixedly connected to the outside of the extrusion block, the top surfaces of the two vertical cones are fixedly connected to the same connecting plate, the bottom surface of the connecting plate is fixedly connected to a rubber strip, and a positioning groove is provided on the inner wall of the positioning cylinder.

[0012] Preferably, the vertical cone slides through the insert and the plastic cover, and the bottom surface of the vertical cone has an inclined cone surface, which is in contact with the extrusion ball located inside the plastic cover.

[0013] Preferably, the extrusion ball located on the outside of the plastic cover is fitted into the positioning groove.

[0014] Preferably, the inner bottom surface of the groove has a through hole, through which the plastic cover passes.

[0015] Preferably, the insert fits into the slot.

[0016] Preferably, the extruded circular block is in contact with the surface of the connecting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This convenient replaceable and detachable toilet seat ring achieves one-click quick installation and removal of the toilet seat ring through the eccentric rotational extrusion structure and the deformation cooperation of the plastic cover. Moreover, the eccentric dead point and the rubber reaction force form a self-locking mechanism, ensuring a stable installation without loosening. The specific details are as follows:

[0018] 1. The rotating shaft and the extrusion block are eccentrically fixed and equipped with a crank handle, allowing users to easily control the rotation of the extrusion block by simply pressing and rotating the handle. This, in turn, drives the vertical cone to move up and down via the connecting plate. The inclined conical surface of the bottom of the vertical cone engages with the extrusion ball on the inner wall of the plastic cover, achieving deformation control of the plastic cover. This allows the extrusion ball located on the outside of the plastic cover to accurately engage in the positioning groove, completing the quick fixation of the toilet seat body to the toilet surface. Conversely, disassembly can be achieved quickly by operating the crank handle and hooking the connecting plate in the opposite direction. In addition, the extrusion of the rubber strip and the surface of the mounting block, as well as the eccentric dead point design of the extrusion block, ensure that the extrusion block will not naturally rotate and reset during use. This makes the toilet seat more stable after installation and prevents it from easily loosening, providing users with a more reliable user experience. The entire process avoids threaded and spring structures, increasing the service life and maintenance convenience of this type of toilet seat in humid environments. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4The present invention provides a technical solution: a convenient replaceable and detachable toilet seat ring, including a toilet seat ring body 1 and a toilet surface 103 on which the toilet seat ring body 1 is installed. The toilet seat ring body 1 includes a seat cushion 101 and a cover plate 102.

[0026] The back of the seat cushion 101 is provided with a quick-release assembly 2, which includes a mounting block 201. The mounting block 201 is symmetrically and rotatably mounted on the back of the seat cushion 101. The top surface of the mounting block 201 is symmetrically and fixedly connected with a vertical plate 202. A rotating shaft 203 is fixedly connected between the vertical plates 202. A pressing round block 204 is rotatably sleeved on the outside of the rotating shaft 203. An insert 207 is fixedly connected to the bottom surface of the mounting block 201. A vertical cone 205 slides vertically through the middle of the mounting block 201.

[0027] The bottom surface of the insert 207 is fixedly connected to a plastic cover 208. The plastic cover 208 has four split grooves 2081 on its exterior, which allow the plastic cover 208 to expand and deform outward. Extrusion balls 209 are fixedly embedded in both the outer and inner walls of the plastic cover 208.

[0028] The toilet seat 103 has a pair of grooves 210 on its top surface and a positioning cylinder 212 fixedly connected to its bottom surface. By inserting the insert 207 into the groove 210 and allowing the plastic cover 208 to pass through the through hole 211, and then pressing the crank handle 2041, the extrusion block 204 rotates and extrudes the connecting plate 206, thereby causing the vertical cone 205 to descend.

[0029] The rotating shaft 203 is eccentrically fixedly connected to the extrusion block 204. A crank 2041 is fixedly connected to the outside of the extrusion block 204. The top surfaces of the two vertical cones 205 are fixedly connected to the same connecting plate 206. A rubber strip is fixedly connected to the bottom surface of the connecting plate 206. A positioning groove 213 is opened on the inner wall of the positioning cylinder 212. After the connecting plate 206 drives the vertical cones 205 to descend, the rubber strip will press the surface of the mounting block 201. After the extrusion block 204 is in the rotated and locked state, the eccentric setting with the rotating shaft 203 makes the extrusion block 204 at the dead point. With the reaction force of the rubber strip, the extrusion block 204 cannot rotate and reset naturally, thus forming an automatic lock.

[0030] The vertical cone 205 slides through the insert 207 and the plastic cover 208. The bottom surface of the vertical cone 205 has an inclined cone surface 2051, which is in contact with the extrusion ball 209 located inside the plastic cover 208. When the inclined cone surface 2051 descends, it will press against the extrusion ball 209 on the inner wall of the plastic cover 208, thereby causing the plastic cover 208 to shift outward. This causes the extrusion ball 209 located outside the plastic cover 208 to be stuck in the positioning groove 213, preventing the plastic cover 208 from moving vertically. Finally, the toilet seat body 1 is quickly connected and fixed to the toilet surface 103. After the crank handle 2041 is reset, the vertical cone 205 is moved upward by pulling the connecting plate 206. The plastic cover 208 returns to its original shape, and finally the extrusion ball 209 is disengaged from the positioning groove 213. At this time, the plastic cover 208 can be raised and lowered vertically, achieving quick disassembly.

[0031] The extrusion ball 209 located outside the plastic cover 208 is fitted with the positioning groove 213; the extrusion ball 209 is a hemisphere.

[0032] The inner bottom surface of the groove 210 is provided with a through hole 211, through which the plastic cover 208 passes; the diameter of the through hole 211 is greater than the maximum spacing of the extrusion balls 209.

[0033] The insert 207 is fitted into the groove 210; after the insert 207 is embedded into the groove 210, the insert 207 cannot wobble, thereby preventing the toilet seat body 1 from wobble and increasing its horizontal stability after installation.

[0034] The extruded round block 204 is bonded to the surface of the connecting plate 206.

[0035] Working principle: Before using this convenient replaceable toilet seat, you need to check the overall condition of the device to ensure it can work properly. Figure 1 - Figure 4 As shown, when installing the toilet seat, first insert the block 207 of the toilet seat body 1 into the groove 210 of the toilet surface 103, and at the same time let the plastic cover 208 pass through the through hole 211.

[0036] Next, press the crank handle 2041 to make the extrusion block 204 rotate around the shaft 203. The extrusion block 204 extrudes the connecting plate 206, causing the vertical cone 205 to descend. The inclined cone surface 2051 of the bottom of the vertical cone 205 extrudes the extrusion ball 209 on the inner wall of the plastic cover 208, causing the plastic cover 208 to deform outward. The extrusion ball 209 located on the outer side of the plastic cover 208 is inserted into the positioning groove 213 on the inner wall of the positioning cylinder 212, realizing the quick docking and fixing of the toilet seat body 1 and the toilet surface 103.

[0037] At the same time, the rubber strip on the bottom surface of the connecting plate 206 presses against the surface of the mounting block 201, and the pressing round block 204 is eccentrically set with the rotating shaft 203, so that the pressing round block 204 is at a dead point. Combined with the reaction force of the rubber strip, the pressing round block 204 cannot rotate and reset naturally, thus forming an automatic lock.

[0038] When disassembling the toilet seat, reset the crank handle 2041, pull the connecting plate 206 to move the vertical cone 205 upward, restore the plastic cover 208 to its original shape, and disengage the squeeze ball 209 from the positioning groove 213. At this time, the plastic cover 208 can be raised and lowered vertically, so that the toilet seat body 1 can be quickly removed from the toilet surface 103.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
