Description

Technical Field

[0001] This invention belongs to the technical field of toilet seat and its connecting device, specifically relating to a spring-loaded locking and unlocking connecting mechanism and its toilet seat. Background Technology

[0002] Toilet seats are typically connected to the toilet using connectors, and in actual 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 designs in the center, or two-button side-press designs. For example, the large center groove at the rear of the seat affects the overall appearance of the toilet, and the button area is prone to dirt and bacteria accumulation. Furthermore, the structure is complex and disassembly / reassembly is cumbersome. Two-button side-press seats, on the other hand, have disadvantages such as cumbersome pressing on both sides and requiring more installation space. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a spring-loaded locking and unlocking connection mechanism and a toilet seat with the same mechanism. The toilet seat with this connection mechanism can be quickly installed and removed by the user simply by pressing the seat assembly, thus solving the problems mentioned in the background art.

[0004] One of the technical solutions adopted by the present invention to solve its technical problem is: a spring-locking and unlocking connection mechanism is provided, including a sleeve assembly and a support assembly; the support assembly is inserted into the sleeve assembly, and the sleeve assembly includes a rotating sleeve, a fixed rotating shaft and a spring-locking core arranged axially in series in the sleeve.

[0005] The fixed rotating shaft is provided with a top block and a limiting slider. The rotating shaft sleeve is used to control the top block to move in the horizontal direction. A clearance space is left above the limiting slider. The top block moves in and out of the clearance space to realize the locking and unlocking of the limiting slider in the vertical direction.

[0006] The bouncing core includes a bushing and a pawl, a sliding pawl, and an elastic reset member axially connected in series within the bushing. The limiting slider has an inclined surface, and the pawl engages with the support assembly above the inclined surface. When the limiting slider moves, the inclined surface pushes the pawl to move horizontally, thereby unlocking the pawl from the support assembly. The sliding pawl and the pawl are engaged by teeth, and a locking unit is provided between the pawl and the bushing. The elastic reset member is used to reset the pawl.

[0007] The locking unit includes a guide rail rib, a ratchet, and a positioning groove. The guide rail rib is disposed on the peripheral wall of the sliding pawl, and the ratchet and positioning groove are disposed on the inner wall of the bushing. When the pawl drives the sliding pawl to rotate, the guide rail rib and the positioning groove engage in a limiting fit.

[0008] The reset unit includes an elastic reset element, which is connected to the end of the slide claw away from the chuck.

[0009] In a preferred embodiment of the present invention, the rotating shaft sleeve is provided with a concave-convex structure, one end of the top block abuts against the concave-convex structure of the rotating shaft sleeve, and the concave-convex structure pushes the top block to move in the horizontal direction as the rotating shaft sleeve rotates.

[0010] In a preferred embodiment of the present invention, the top block is provided with a pointed tip and a protrusion, the pointed tip and the protrusion facing opposite directions, the pointed tip abutting against the concave and convex structure of the rotating bushing, and the protrusion adapting to the clearance space.

[0011] In a preferred embodiment of the present invention, a return spring is provided between the end of the top block facing the protrusion and the connection point of the fixed rotating shaft.

[0012] In a preferred embodiment of the present invention, the support assembly includes a support shaft, which passes through a limiting slider and is inserted into a fixed rotating shaft, and the peripheral wall of the support shaft is provided with a snap-fit ​​portion.

[0013] In a preferred embodiment of the present invention, a limiting spring is sleeved on the support shaft, and the limiting spring is used to reset the limiting slider.

[0014] In a preferred embodiment of the present invention, the peripheral wall of the support shaft is provided with a step, and the limiting slider is mounted on the step.

[0015] In a preferred embodiment of the present invention, the bushing is provided with a pawl, a sliding pawl, an elastic reset member and a bottom cover connected in series.

[0016] In a preferred embodiment of the present invention, the two ends of the pawl are respectively provided with a pawl head and a first tooth surface. The pawl head is inserted into the fixed rotating shaft and engaged with the pawl head of the support shaft. The tooth surface is connected to the sliding pawl.

[0017] In a preferred embodiment of the present invention, a second toothed surface is provided at the connection between the sliding pawl and the pawl, and the pawl moves towards the sliding pawl in a horizontal direction. The sliding pawl rotates by switching between the offset and engagement states of the second toothed surface and the first toothed surface.

[0018] In a preferred embodiment of the present invention, the locking unit includes a guide rail rib, a ratchet, and a positioning groove. The guide rail rib is disposed on the peripheral wall of the sliding pawl, and the ratchet and the positioning groove are disposed on the inner wall of the bushing. When the pawl drives the sliding pawl to rotate, the guide rail rib and the positioning groove engage in a limiting fit.

[0019] In a preferred embodiment of the present invention, the ratchet teeth of the bushing are arranged along the circumferential direction and include a positioning surface and a guide surface arranged in sequence.

[0020] In a preferred embodiment of the present invention, the positioning groove is located downstream of the guide surface, and the guide rail ribs switch positions with the guide surface or with the positioning groove as the sliding claw rotates.

[0021] In a preferred embodiment of the present invention, a locking arc surface is provided downstream of the positioning groove.

[0022] The second technical solution adopted by the present invention to solve its technical problem is: a toilet seat is provided, including a seat assembly and the above-mentioned spring-loaded locking and unlocking connection mechanism, wherein the sleeve assembly is disposed at the rear end of the seat assembly and the support assembly is fixed to the toilet seat body.

[0023] In a preferred embodiment of the present invention, the sleeve assembly has a damping element, a rotating sleeve, a fixed rotating shaft and a spring core arranged axially in series and symmetrically at both ends inside the sleeve.

[0024] In a preferred embodiment of the present invention, the peripheral wall of the rotating bushing is provided with a raised rib along the axial direction, and a slot is provided at the connection between the rear end of the cover plate assembly and the sleeve assembly. The slot is inserted into the raised rib and rotates as the cover plate assembly flips.

[0025] Compared with the prior art, this technical solution has the following advantages:

[0026] 1. The connecting mechanism of this invention enables quick assembly and disassembly of the toilet seat assembly through the cooperation of the sleeve assembly and the support assembly; the internal structure design of the rotating sleeve and the fixed rotating shaft drives the movement of the top block through the rotating sleeve, thereby limiting and releasing the limiting slider, realizing the first layer of locking and unlocking;

[0027] 2. The connecting mechanism of the present invention changes the direction of force by the inclined surface of the limiting slider, thereby realizing the linkage between the limiting slider and the pawl. Then, through the self-locking and anti-self-locking reset of the bushing, sliding pawl, pawl, and elastic reset component, a second layer of locking and unlocking is achieved.

[0028] 3. The toilet seat of the present invention establishes a linkage between the flipping of the seat assembly and the rotation of the rotating shaft sleeve through the slot and the rib, so that the user can achieve the first locking and unlocking of the above-mentioned connection mechanism by flipping the seat assembly.

[0029] 4. After the toilet seat of this invention is first unlocked, the user only needs to apply longitudinal force to the pressing seat assembly. Under the action of the inclined surface of the limiting slider, the claw can be controlled to unlock the support assembly, achieving quick disassembly. The anti-locking reset in the bushing can also reset the claw, thereby achieving quick installation. During the operation, the user does not need to change the action. He can control the quick disassembly and assembly by simply pressing the toilet seat assembly, which is ingenious and labor-saving. Attached Figure Description

[0056] Example 1

[0057] This embodiment provides a toilet seat, such as... Figure 1 and 2 The toilet includes a cover assembly consisting of a top cover 4 and a seat ring 3. The cover assembly is connected to the toilet seat body via a spring-loaded locking and unlocking mechanism. The spring-loaded locking and unlocking mechanism includes a sleeve assembly 2 and a support assembly 1. The sleeve assembly 2 is located at the rear end of the cover assembly, and the support assembly 1 is fixed to the toilet seat body and has a support shaft 11 inserted into the sleeve assembly 2.

[0058] like Figure 3 and 7 The sleeve assembly 2 has a damper 21, a rotating sleeve 22, a fixed rotating shaft 23 and a spring core 24 arranged axially in series and symmetrically at both ends inside the sleeve 25.

[0059] The circumferential wall of the rotating sleeve 22 is provided with a rib 236 along the axial direction. The connection between the rear end of the seat ring 3 of the cover plate assembly and the sleeve assembly 2 is a connecting ring 31. The connecting ring 31 is provided with a groove 32. The groove 32 is inserted into the rib 236 and rotates with the flip of the cover plate assembly. The rotating sleeve 22 is sleeved with the fixed rotating shaft 23. The rotating sleeve 22 is provided with a concave-convex structure. In this embodiment, the concave-convex structure is composed of two planes 2211 and 2212 with different distances from the center of the sleeve 25 and a slope 2222 that smoothly transitions between the two. The concave-convex structure causes the distance between the tip 2311 and the center of the sleeve 25 in the axial direction to change as the rotating sleeve 22 rotates.

[0060] like Figure 4 The fixed rotating shaft 23 has a support hole 232, and the support shaft 11 is inserted into the support hole 232. A limiting slider 233 and a limiting spring 235 are sequentially sleeved on the support shaft 11. The upper end of the limiting spring 235 abuts against the support hole 232. The peripheral wall of the support shaft 11 has a step 13. The bottom of the limiting slider 233 has a countersunk hole 2332 that cooperates with the step 13, so that the limiting slider 233 is mounted on the step 13. A clearance space 2321 is left between the upper part of the limiting slider 233 and the inner wall of the fixed rotating shaft 23. The limiting slider 233 slides up and down at the location of the clearance space 2321 and is reset by the compression of the limiting spring 235.

[0061] The fixed rotating shaft 23 is provided with a top block 231 and a limiting slider 233. One end of the top block 231 has a pointed tip 2311, which abuts against the concave-convex structure of the rotating shaft sleeve 22. The concave-convex structure pushes the top block 231 to move horizontally as the rotating shaft sleeve 22 rotates. The other end of the top block 231 has a protrusion 2312, and the upper part of the protrusion 2312 is adapted to the clearance space 2321. A return spring 234 is provided between the top block 231 and the fixed rotating shaft 23 at the connection point above the protrusion 2312. Under the control of the concave-convex structure of the rotating shaft sleeve 22, the top block 231 moves horizontally, and the protrusion 2312 of the top block 231 moves in and out of the clearance space 2321, restricting the up and down sliding of the limiting slider 233, thereby realizing the locking and unlocking of the limiting slider 233 in the vertical direction, that is, the first locking and unlocking.

[0062] like Figure 8 The bouncing core 24 includes a bushing 241 and a claw 242, a sliding claw 243, an elastic reset member 244, and a bottom cover 245 axially connected in series within the bushing 241; the limiting slider 233 is provided with an inclined surface 2331, which is inclined downward from the support shaft 11 toward the center of the sleeve 25.

[0063] like Figure 11The claw 242 is provided with a claw head 2421, and the claw head 2421 is provided with an arc surface 2422, such as Figure 12 The support shaft 11 is provided with a locking part 12. The arc surface 2422 of the locking head 2421 is inserted into the locking part 12 and locked with it to prevent the support shaft 11 from coming out of the support hole 232. The claw 242 is provided with a push rod 2423 below the locking head 2421. The push rod 2423 abuts against the inclined surface 2331 and works together to convert the vertical movement of the limiting slider 233 into the horizontal movement of the claw 242. That is, when the cover plate is pressed, the entire sleeve assembly moves downward. The push rod 2423, which includes the claw in the sleeve assembly, moves downward. At this time, due to the obstruction of the inclined surface 2331, the push rod 2423 is pushed horizontally towards the claw 243, and the locking head 2421 comes out of the locking groove, thereby unlocking the claw 242 from the support shaft 11. The support shaft 11 can then come out of the support hole 232.

[0064] like Figure 8 and 9 The sliding pawl 243 has a first tooth surface 2424 in the opposite direction of the chuck 2421, and a second tooth surface 2431 is provided at the connection between the sliding pawl 243 and the chuck 242. The sliding pawl 243 and the chuck 242 are engaged by teeth. The chuck 242 moves towards the sliding pawl 243 in the horizontal direction. The rotation of the sliding pawl 243 is achieved by the switching between the staggered and engaged states of the second tooth surface 2431 and the first tooth surface 2424.

[0065] Furthermore, the peripheral wall of the sliding pawl 243 is provided with guide rail ribs 2432, and the inner wall of the bushing 241 is provided with ratchet teeth and positioning grooves 2413. The ratchet teeth of the bushing 241 are arranged in a circumferential direction to form positioning surfaces 2412 and guide surfaces 2411 arranged in a sequential cycle. The positioning groove 2413 is oriented along the axial direction and is located at the junction of the previous guide surface 2411 and the next positioning surface 2412. The opening of the positioning groove 2413 away from the guide surface 2411 is provided with a locking arc surface 2414, and the downstream of the locking arc surface 2414 is connected to the next level guide surface 2411. The guide rail ribs 2432 switch positions with the sliding pawl 243 as they rotate, either abutting against the guide surface 2411 or inserting into the positioning groove 2413. When the pawl 242 drives the sliding pawl 243 to rotate, the guide rail rib 2432 and the positioning groove 2413 are in a limiting engagement, and the pawl 242 achieves self-locking and anti-self-locking reset under the action of the elastic reset member 244.

[0066] The connecting mechanism in this embodiment has a double-locking and unlocking function:

[0067] ① Figure 5For example, at the connection between the left support assembly 1 and the sleeve assembly 2, when the seat ring 3 is in a vertical state, the tip 2311 of the top block 231 abuts against the plane 2211 of the concave-convex structure. The top block 231 is located at the leftmost end, and the protrusion 2312 of the top block 231 is outside the clearance space 2321, which does not restrict the displacement of the limit slider 233. This state is the first unlocking state.

[0068] When a downward force is applied to the cover plate assembly, the platform of the support shaft 11 presses against the countersunk hole 2332 of the limiting slider 233, causing the limiting slider 233 to enter the clearance space 2321. The inclined surface 2331 of the limiting slider 233 pushes the claw 242 to the right, causing the claw head 2421 to disengage from the locking part 12 of the support shaft 11.

[0069] At this time, as Figure 13 The guide rail rib 2432 of the sliding pawl 243 slides from the guide surface 2411 of the bushing 241 to the positioning surface 2412 and abuts against the positioning surface 2412. At this time, even if the tooth surfaces of the pawl 242 and the sliding pawl 243 are misaligned, the sliding pawl 243 cannot rotate, and the pawl 242 remains in the position of being disengaged from the locking part 12 of the support shaft 11.

[0070] The cover plate assembly can be separated from the support assembly 1 for quick disassembly.

[0071] ② Apply a downward force to the cover plate assembly again, such as Figure 14 When the chuck 242 moves to its maximum stroke, the tooth surfaces of the chuck 242 and the slide 243 change from a relatively offset (tooth tips facing each other) state to an engaged state, causing the slide 243 to rotate. The slide 243 crosses the positioning surface 2412 to reach the next guide surface 2411 and slides into the positioning groove 2413; Figure 15 When the hand stops applying force, under the action of the elastic reset member 244 (such as a spring), the guide rail rib 2432 of the sliding claw 243 slides into the positioning groove 2413, pushing the claw 242 to slide to the left, so that the clamp head 2421 re-embeds into the clamping part 12 of the support shaft 11.

[0072] Figure 6 When the seat ring 3 is rotated to a horizontal position, the groove 32 in the connecting ring 31 drives the rib 236 of the rotating sleeve 22 to move. The rotating sleeve 22 rotates through a certain angle, so that the tip 2311 of the top block 231 abuts against the plane 2212 of the concave-convex structure 222. Since the plane 2212 is closer to the center of the sleeve 25 than the plane 2211, the top block 231 is pushed to the right and displaced. The protrusion 2312 of the top block 231 enters the clearance space 2321, which restricts the upward movement of the limit slider 233. This state is the second locking state.

[0073] The cover plate assembly is then connected to the support assembly 1, enabling rapid installation.

[0074] ③ For example Figure 16 In the first unlocked state, a downward force is applied to the cover plate assembly again. The rightward sliding guide rib 2432 of the claw 242 slides from the positioning groove 2413 to the locking arc surface 2414. Since the locking arc surface 2414 is farther from the center of the sleeve than the guide surface 2411, when the guide rib 2432 abuts against the locking arc surface 2414, the claw 242 remains in the position of disengaging from the support shaft 11 engagement part 12. The force is continued to be applied. When the claw 242 moves to the right to the maximum stroke, the guide rib 2432 crosses the locking arc surface 2414 and reaches the next guide surface. The cyclic disassembly and assembly state transition can be achieved by pressing repeatedly.

[0075] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
