Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of toilet seat connection devices, specifically relating to a spring-loaded core and a toilet seat connection mechanism. Background Technology
[0002] Toilet seats are typically connected to the toilet using connectors. In practical use, the seat often needs to be disassembled for cleaning or replacement. Most existing toilet seat quick-release mechanisms are mechanical button unlocking, such as common two-button or one-button, or two-button side-press types. For example, a toilet seat hinge structure disclosed in Chinese utility model (CN209059019U) requires continuous pressing of a button to disassemble the toilet seat. This causes the sliding member to move inwards relative to both ends of the outer shell, keeping the limiting rod disengaged from the rotating joint's limiting groove. The rotating joint and fixing pin can then move downwards relative to the outer shell, allowing the toilet seat to be lifted vertically for quick disassembly. For installation, pressing the button again causes the sliding member to retract, and the fixing pin pushes against the rotating joint, passing through the mounting through hole and the second through hole. Releasing the button moves the sliding member towards the end of the outer shell, and the limiting rod abuts against the rotating joint. The limiting rod then engages the limiting groove, allowing the toilet seat to be installed. However, this type of quick-release toilet seat with mechanical buttons requires pressing the button continuously during installation or removal to keep the limit rod detached from the rotary joint (or support shaft), which is very inconvenient. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bouncing core and toilet seat connection mechanism, which solves the problems mentioned in the background art.
[0004] The technical solution adopted by the present invention to solve its technical problem is: to provide a bouncing core, including a bushing, a limiting rod, a rotating part 13 and an elastic reset part;
[0005] The limiting rod is used to engage with the limiting groove of the support shaft for limiting. The end of the limiting rod and the rotating part 13 are dynamically matched by a toothed structure that is staggered or meshed with each other. The elastic reset member is located at the end of the rotating part 13 away from the limiting rod.
[0006] The end of the limiting rod, the rotating component 13, and the elastic reset component are sequentially connected in series inside the bushing. The peripheral wall of the rotating component 13 is provided with guide rail ribs, and the inner wall of the bushing is provided with a ratchet surface and a positioning groove. As the rotating component 13 rotates, the guide rail ribs abut against the ratchet surface or insert into the positioning groove.
[0007] When the guide rail rib abuts against the ratchet surface, the rotating component 13 is fixed, the elastic reset component accumulates elastic force, and the limiting rod is disengaged from the limiting groove; when the guide rail rib is inserted into the positioning groove, the elastic reset component releases the elastic force, and the rotating component 13 and the limiting rod return to their initial positions, realizing the limiting rod and the limiting groove either locking or limiting.
[0008] In a preferred embodiment of the present invention, the ratchet surface includes a guide slope and a positioning surface arranged sequentially along the circumferential direction.
[0009] In a preferred embodiment of the present invention, the guide slope is inclined at the location of the limiting rod in the downstream direction of the rotating member 13, the positioning surface is set at the end point of the guide slope, and forms an angle of no more than 180 degrees with the guide slope, and the next level guide slope is set at the end point of the positioning surface.
[0010] In a preferred embodiment of the present invention, the positioning grooves are spaced apart along the circumferential direction and are located at the end of the adjacent guide slope.
[0011] In a preferred embodiment of the present invention, the positioning groove is provided with a locking arc surface in the downstream direction of the rotating member 13, and the end point of the locking arc surface is connected to the next level of guide slope.
[0012] In a preferred embodiment of the present invention, the end of the guide rail rib is provided with an inclined surface, which is adapted to the guide slope.
[0013] In a preferred embodiment of the present invention, a bottom cover is also included, and the end of the limiting rod, the rotating member 13, the elastic reset member, and the bottom cover are sequentially connected in series inside the bushing.
[0014] In a preferred embodiment of the present invention, the bushing is provided with a slot, the bottom cover is provided with a locking foot, and the locking foot engages with the slot.
[0015] In a preferred embodiment of the present invention, the limiting rod is connected to the driving mechanism.
[0016] Compared with the prior art, this technical solution has the following advantages:
[0017] 1. This invention provides a rotating component 13 and an elastic reset component along the displacement path of the limiting rod, with a bushing fitted around its outer circumference. The structure of the rotating component 13 and the bushing enables the rotating component 13 to self-lock, keeping the limiting rod disengaged from the limiting groove of the support shaft. After the rotating component 13 continues to rotate, the elastic force provided by the elastic reset component enables the rotating component 13 to reverse self-lock, returning the limiting rod to its engaged state with the limiting groove of the support shaft. This allows for quick assembly and disassembly of the support shaft with a single press of the drive mechanism.
[0018] 2. The present invention has a locking arc surface at the end of the positioning groove, which breaks the engagement state between the rotating part 13 and the limiting rod, so that the two return to the staggered and abutting state, providing a basis for the next self-locking and anti-self-locking, thereby realizing the cyclic possibility of the driving mechanism driving the displacement of the limiting rod.

[0029] Example 1
[0030] This embodiment provides a toilet seat connection mechanism for connecting the seat ring 3, the top cover 4, and the toilet seat body. The seat ring 3 and the top cover 4 are provided with sleeves. The sleeves are provided with a drive mechanism 5 (including but not limited to button mechanisms set on both sides of the sleeve, any device that can push the limiting rod 12 to move in the horizontal direction), a damping element, and a spring core 1. The spring core 1 is limited and engaged with the support shaft 2, and the support shaft 2 is fixed to the toilet seat body.
[0031] The bouncing core 1 in this embodiment includes a bushing 11, and a limiting rod 12, a rotating member 13, an elastic reset member 14, and a bottom cover 15 arranged in series within the bushing 11. The bushing 11 is provided with a slot, and the bottom cover 15 is provided with a locking foot, which engages with the slot.
[0032] One end of the limiting rod 12 is provided with a locking head 121 for engaging with the limiting groove 22 of the support shaft 2 for limiting the position. The other end of the limiting rod 12 is provided with a toothed surface 124, and the end of the rotating part 13 is provided with a toothed surface 131. The two are dynamically engaged by means of mutual offset or interlocking of the toothed structure. The elastic reset part 14 is provided at the end of the rotating part 13 away from the limiting rod 12.
[0033] The end of the limiting rod 12, the rotating component 13, and the elastic reset component 14 are sequentially connected in series inside the bushing 11. The peripheral wall of the rotating component 13 is provided with guide rail ribs 132, and the inner wall of the bushing 11 is provided with a ratchet surface and a positioning groove 113. As the rotating component 13 rotates, the guide rail ribs 132 abut against the ratchet surface or insert into the positioning groove 113 respectively.
[0034] When the guide rail rib 132 abuts against the ratchet surface, the rotating member 13 is fixed, the elastic reset member 14 accumulates elastic force, and the limiting rod 12 is disengaged from the limiting groove; when the guide rail rib 132 is inserted into the positioning groove 113, the elastic reset member 14 releases the elastic force, and the rotating member 13 and the limiting rod 12 return to their initial positions, realizing the limiting rod 12 and the limiting groove 22 either locking or limiting.
[0035] In this embodiment, the ratchet surface includes a guide surface 111 and a positioning surface 112 arranged sequentially along the circumferential direction. The guide slope is inclined at the location of the limiting rod 12 in the downstream direction of the rotating member 13. The positioning surface 112 is located at the end point of the guide slope, forming an acute angle with the guide slope. The next level guide slope is located at the end point of the positioning surface 112. The positioning grooves 113 are spaced apart along the circumferential direction and are located at the end point of the adjacent guide slope. The positioning grooves 113 are provided with a locking arc surface 114 in the downstream direction of the rotating member 13.
[0036] To ensure that the rotating component 13 and the bushing 11 can achieve self-locking and anti-self-locking more stably, the end of the guide rail rib 132 is provided with an inclined surface, which is adapted to the guide slope, and the positioning surface 112 is parallel to the side wall of the guide rail rib 132.
[0037] Taking the connection between the left support assembly 1 and the sleeve assembly 2 as an example, the movement process of this embodiment will be explained:
[0038] like Figure 6 When the drive mechanism 5 pushes the limit rod 12 to the right, the chuck 121 disengages from the limit groove 22 of the support shaft 2; the guide rail rib 132 of the rotating part 13 slides from the guide surface 111 of the bushing 11 to the positioning surface 112 and abuts against the positioning surface 112; when the drive mechanism 5 is released, even if the limit rod 12 and the tooth surface of the rotating part 13 are misaligned, the rotating part 13 cannot rotate, and the limit rod 12 remains in the position disengaged from the limit groove 22 of the support shaft 2;
[0039] The top cover 4 and seat ring 3 can be separated from the support assembly 1 for quick disassembly;
[0040] like Figure 7 Press the drive mechanism 5 again to move the limit rod 12 to the right to its maximum stroke. The tooth surfaces of the limit rod 12 and the rotating part 13 change from being relatively misaligned (tooth tips facing each other) to being engaged, causing the rotating part 13 to rotate. The rotating part 13 passes over the positioning surface 112 to reach the next level guide surface 111 and slides into the positioning groove 113; Figure 8 When the drive mechanism 5 is released, under the action of the elastic reset member 14 (such as a spring), the guide rail rib 132 of the rotating member 13 slides into the positioning groove 113, pushing the limit rod 12 to slide to the left, so that the chuck 121 is re-embedded into the limit groove 22 of the support shaft 211, thus achieving quick disassembly.
[0041] like Figure 9 Press the drive mechanism 5 again, and the limit rod 12 moves to the right. The guide rail rib 132 slides from the positioning groove 113 to the locking arc surface 114. The pawl 242 remains in the position where it is disengaged from the support shaft 11 and the locking part 12. Continue to apply force. When the limit rod 12 moves to the right to the maximum stroke, the guide rail rib 132 crosses the locking arc surface 114 and reaches the next guide surface. The cyclic disassembly and assembly state can be changed by pressing repeatedly.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
