Description

Technical Field

[0001] The utility model relates to the technical field of seats, and particularly relates to a rotary seat mechanism with multi-angle locking. Background Art

[0002] The locking positions of existing rotary seats generally only have two gears, 0° and 180°, and both are in the form of pin or locking claw locking.

[0003] For example, the Chinese utility model patent authorization publication number CN220615558U discloses a vertical pin locking mechanism for a rotary seat. In this patent, a locking hole is provided on a fixed disk in a seat rotation mechanism, and a locking pin hole is provided on a rotating disk. When the locking hole and the locking pin hole are aligned, a locking pin vertically passes through the locking pin hole and inserts into the locking hole to realize the locking of the fixed disk and the rotating disk.

[0004] In addition, for example, a gapless locking mechanism for a rotary seat disclosed in the Chinese utility model patent authorization publication number CN209474126U has a locking hole provided on the outer circumference of a fixed disk, and a locking bracket is installed on the rotating disk. A horizontally movable locking pin is provided on the locking bracket, and the locking pin inserts into the locking hole during locking.

[0005] In the above two existing patents, locking is achieved by inserting a locking pin into a locking hole on the fixed disk, and the position where the locking hole is provided on the fixed disk is generally fixed. Therefore, there is only one locking position in the two existing patents, and it is impossible to realize the locking of the rotary seat at any angle between 0° and 360°.

[0006] In the existing patents, locking is achieved by inserting a locking pin into a locking hole on the fixed disk. Whether it is horizontal locking or vertical locking, the locking pin needs to withstand high-strength torsional failure strength, which puts higher strength requirements on the locking pin. During locking, the locking pin and the locking hole are generally in close contact (if not in close contact, there will be abnormal noises), so a large unlocking force is required to unlock. At the same time, when the locking pin is inserted into or pulled out of the locking hole, there will be a scraping sound, making the locking sound and unlocking sound large.

[0007] In addition, in the existing patents, a locking and unlocking mechanism needs to be additionally provided, which requires a certain amount of space under the seat. Utility Model Content

[0008] The technical problem to be solved by the utility model is to provide a multi-angle locking rotary seat mechanism that can lock at any angle of 360° in a full circle, utilizes an existing angle adjuster that can withstand high-strength torsional failure strength, has a small unlocking force, no scraping sound, and a simple structure, and does not require much additional space under the seat, aiming at the above technical problems existing in the existing rotary seat locking mechanism.

[0009] The technical problems to be solved by the present utility model can be achieved through the following technical solutions:

[0010] A rotating seat mechanism with multi-angle locking, comprising a fixed seat pan and a movable seat pan. It is characterized in that it further comprises an angle adjuster, which is installed between the fixed seat pan and the movable seat pan. Among them, the angle adjuster is a manual concentric angle adjuster. The fixed part of the manual concentric angle adjuster is fixedly connected to the fixed seat pan and is concentric with the movable seat pan. The rotating part of the manual concentric angle adjuster is fixedly connected to the movable seat pan; the angle adjuster can be locked at any angle within the range of 0° to 360°, so that the movable seat pan is locked relative to the fixed seat pan at any angle within the range of 0° to 360°.

[0011] In a preferred embodiment of the present utility model, the manual concentric angle adjuster, the fixed seat pan and the movable seat pan are concentrically arranged.

[0012] In a preferred embodiment of the present utility model, the fixed part of the manual concentric angle adjuster is fixed on a first connecting plate, and the first connecting plate is installed on the fixed seat pan by fasteners; the movable part of the manual concentric angle adjuster is fixed on a second connecting plate, and the second connecting plate is installed on the movable seat pan by fasteners.

[0013] In a preferred embodiment of the present utility model, the manual concentric angle adjuster has an unlocking handle, and the unlocking handle extends outwards through the movable seat pan.

[0014] In a preferred embodiment of the present utility model, the unlocking handle is installed on the manual concentric angle adjuster through a pair of thrust caps.

[0015] In a preferred embodiment of the present utility model, a pair of thrust caps are respectively located on both sides of the axis direction of the manual concentric angle adjuster.

[0016] In a preferred embodiment of the present utility model, an electric mechanism is installed on the unlocking handle. The electric mechanism drives the unlocking handle to unlock the manual concentric angle adjuster and drives the rotating part in the manual concentric angle adjuster to rotate through the unlocking handle, and further drives the relative concentric rotation of the movable seat pan and the fixed seat pan.

[0017] In a preferred embodiment of the present utility model, a stroke control disc mechanism is added to the manual concentric angle adjuster, which can make the movable seat pan not locked within a certain angle and locked at a fixed position.

[0018] Due to the adoption of the above technical solution, the rotating seat mechanism of the present utility model uses a manual concentric angle adjuster to achieve 0°-360° unlocking and locking of the movable disk of the seat pan for a full circle. There are many locking positions. At the same time, the number of parts is small and the structure is simpler. At the same time, while bearing a large torsional failure strength, the unlocking force required for unlocking is small, the locking sound is small, and it is not easy to scratch with other parts. Moreover, the concentric angle adjuster only needs one connecting plate to be installed on the fixed disk of the seat pan, which simplifies the structure and reduces the installation cost.

[0019] In addition, an electric mechanism is added to realize the integration of manual and automatic operation of the angle adjuster. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Embodiment 1

[0026] Refer to Figure 1 , a multi-angle locking rotating seat mechanism shown in the figure, including a fixed disk 5 of the seat pan and a movable disk 1 of the seat pan. The movable disk 1 of the seat pan rotates concentrically relative to the fixed disk 5 of the seat pan.

[0027] The multi-angle locking rotating seat mechanism further includes an angle adjuster, and the angle adjuster is used to realize the concentric rotation of the movable disk 1 of the seat pan relative to the fixed disk 5 of the seat pan.

[0028] The angle adjuster is a manual concentric angle adjuster 2. In this way, the manual concentric angle adjuster 2, the movable disk 1 of the seat pan, and the fixed disk 5 of the seat pan are concentrically installed.

[0029] The present utility model uses the manual concentric angle adjuster 2 to realize the concentric rotation of the movable disk 1 of the seat pan relative to the fixed disk 5 of the seat pan. Compared with the eccentric angle adjuster in the prior art, it has fewer parts, a simpler structure, and lower cost.

[0030] The fixed part of the manual concentric angle adjuster 2 is fixed on a connecting plate 4 (the aforementioned first connecting plate), and the connecting plate 4 is installed on the fixed disk 5 of the toilet seat by fasteners; the movable part of the manual concentric angle adjuster 2 is fixed on a connecting plate 8 (the aforementioned second connecting plate), and the two connecting plates 8 are installed on the movable disk 1 of the toilet seat by fasteners.

[0031] The fixed part of the manual concentric angle adjuster 2 is concentrically welded (other fixing methods can also be used) and fixed on the connecting plate 4. The connecting plate 4 is also concentrically arranged with the fixed disk 5 of the toilet seat and installed on the fixed disk 5 of the toilet seat by four bolts or rivets 3. The rotating part of the manual concentric angle adjuster 2 is concentrically welded to a connecting plate 8 by welding. The connecting plate 8 is also concentrically arranged with the movable disk 1 of the toilet seat and installed on the movable disk 1 of the toilet seat by four bolts or rivets 9.

[0032] The manual concentric angle adjuster 2 is unlocked by an unlocking handle 7. The unlocking handle 7 extends outwards through the movable disk 1 of the toilet seat for easy operation. The unlocking handle 7 is installed on the manual concentric angle adjuster 2 by a pair of thrust caps 6. The pair of thrust caps 6 are respectively located on both sides of the axis direction of the manual concentric angle adjuster 2, which can prevent the unlocking handle 7 from axially moving.

[0033] The manual concentric angle adjuster 2 can adopt the core component of the existing seat, the manual concentric angle adjuster, which can bear a large torsional failure strength and has a small unlocking force required for unlocking. In addition, using the manual concentric angle adjuster 2 as the rotating component of the rotating seat is not easy to scratch with other parts and has a small locking sound.

[0034] After the manual concentric angle adjuster 2 is unlocked by the unlocking handle 7, the manual concentric angle adjuster 2 is unlocked. After the manual concentric angle adjuster 2 is unlocked, the movable disk 1 of the toilet seat can rotate relative to the fixed disk 5 of the toilet seat within the range of 0° to 360°. After the manual concentric angle adjuster 2 is locked, the movable disk 1 of the toilet seat can be locked relative to the fixed disk 5 of the toilet seat at any angle within the range of 0° to 360°, for example, every 2° is a gear position, so that there are many locking gear positions.

[0035] Embodiment 2

[0036] See Figure 2 , the difference between this embodiment and Embodiment 1 is that: the unlocking handle 7 can be driven by an electric mechanism 2a to realize unlocking, so as to realize the integration of manual and automatic operation of the manual concentric angle adjuster 2.

[0037] The electric mechanism 2a is located above the movable disk 1 of the toilet seat and is drivingly connected to the unlocking handle 7, driving the unlocking handle 7 to unlock the manual concentric angle adjuster 2 and driving the rotating part in the manual concentric angle adjuster 2 to rotate through the unlocking handle 7, thereby driving the movable disk 1 of the toilet seat to rotate concentrically relative to the fixed disk 5 of the toilet seat.

[0038] The unlocking handle 7 is mounted on the electric mechanism 2a and the manual concentric angle adjuster 2 through a pair of thrust caps 6. The pair of thrust caps 6 are respectively located on both sides of the electric mechanism 2a and the manual concentric angle adjuster 2 in the axial direction.

[0039] The fixed disk 5 and the movable disk 1 of the toilet bowl of this embodiment are compatible with the electric and manual solutions. It only needs to replace the electric mechanism 2a, the manual concentric angle adjuster 2 and the electric mechanism 2a to achieve the compatible function, and there is no need to newly manufacture molds for the fixed disk 5 and the movable disk 1 of the toilet bowl.

[0040] Embodiment 3

[0041] When the manual concentric angle adjuster 2 is the manual angle adjuster 2a of an existing seat, a stroke control disk mechanism can be added to the manual angle adjuster 2a, so that the movable disk 1 of the toilet bowl is not locked within a certain angle and is locked at a fixed position.

[0042] See Figures 3 to 4 , the stroke control disk mechanism includes a stroke control disk 11 fixed in the rotating part 2aa of the manual angle adjuster 2a and capable of rotating together with the rotating part 2aa of the manual angle adjuster 2a, and a stroke control disk locking block 12 slidably arranged on the fixed part 2ab of the manual angle adjuster 2a and capable of radial movement.

[0043] Especially see Figure 3 , the stroke control disk 11 has an inner ring 11a and an outer ring 11b connected to each other. A plurality of, for example, two sector-shaped grooves 11bb for restricting the rotation of the stroke control disk 11 are arranged at intervals on the inner edge 11ba of the outer ring 11b of the stroke control disk 11. The diameter 11bba of the sector-shaped groove 11bb is greater than the diameter 11baa of the inner edge 11ba of the outer ring 11b of the stroke control disk 11.

[0044] A locking protrusion 12a is arranged on each stroke control disk locking block 12. Especially see Figure 3 and Figure 4 , when the movable disk of the seat plate that rotates with the rotating part 2aa of the manual angle adjuster 2a rotates to the position where it needs to be fixed, the stroke control disk locking block 12 moves radially, so that the locking protrusion 12a on the stroke control disk locking block 12 is embedded into the sector-shaped groove 11bb, performing circumferential locking on the stroke control disk 11 and restricting the circumferential rotation of the stroke control disk 11. Then, the movable disk of the seat plate that rotates with the rotating part 2aa of the manual angle adjuster 2a is locked at a fixed position through the rotating part 2aa of the manual angle adjuster 2a; at the same time, the locking teeth 12b of the stroke control disk locking block 12 are engaged and locked with the teeth 2aaa of the rotating part 2aa of the manual angle adjuster 2a.

[0045] Especially see Figure 4, when the movable disk of the seat disk that rotates following the rotating part 2aa of the manual angle adjuster 2a does not rotate to the position that needs to be fixed, the inner edge 11ba of the outer ring 11b of the stroke control disk 11 rotates relative to the locking projection 12a on the stroke control disk locking block 12, and does not perform circumferential locking on the stroke control disk 11.
