Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent toilets, and in particular relates to a locking mechanism of a movable connecting piece and an application thereof. Background Art

[0002] Smart toilet seats have many functions such as seat heating, warm water flushing, hot air drying, etc. As people's living standards improve, more and more families choose smart toilet seats instead of traditional toilet seats.

[0003] Smart toilet lids on the market typically consist of a cover assembly, a functional mechanism, and an operating mechanism. The cover assembly is typically located at the front of the toilet bowl, with the rear end connected to the functional mechanism. To meet various requirements, the functional mechanism is often equipped with components such as a heating element, a flushing element, or a hot air element. As a result, the functional mechanism is often large and needs to be fixed to the toilet bowl, with minimal distance from the water tank or wall at the rear end of the toilet bowl. Furthermore, due to the movable connection, there is a noticeable gap between the cover assembly and the functional mechanism. This allows only the cover assembly to be moved during use, avoiding the need to lift the bulky and heavy rear functional mechanism, thus saving time and effort.

[0004] However, this structure and movement create cleaning challenges. Existing easy-to-clean smart toilet lids typically focus on cleaning the cover assembly, the toilet seat itself, and the hinged connection between the cover assembly and the rear assembly. The rear functional mechanism, however, is difficult to clean due to its fixed position. However, during use, the gaps and slots in the toilet seat, where the functional mechanism is permanently fixed, are easily contaminated, making them difficult to clean and prone to bacterial growth. This can cause odors in the bathroom and harm human health.

[0005] If some connecting rod devices (such as Figure 12 ) Raising or flipping the functional mechanism at the rear end of the toilet can achieve cleaning of the bottom, but a certain locking device is required to fix it during the process, otherwise the functional mechanism is prone to falling and being damaged. Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a locking mechanism for a movable connecting piece and its application, which solves the problem of locking the position of the functional mechanism when it is lifted or flipped by a connecting rod in the above background technology.

[0007] The technical solution adopted by the present invention to solve the technical problem is: providing a locking mechanism of a movable connecting piece, including a bracket, a travel switch, a support block, a press-type lock and a support rod;

[0008] The bracket is used to fix the locking mechanism to the side of the movable connecting member; the movable connecting member includes a connecting rod and other connecting members that can move in and out of the movable space while the movement trajectory of the support rod is in motion.

[0009] The travel switch includes an operating end and a linkage end, wherein the linkage end is located below the operating end;

[0010] The support block is pivotally connected to the bracket, and the support block is arranged within the travel distance of the linkage end and forms a movable channel with the linkage end;

[0011] The support rod is extended from the movable connecting piece to the vertical plane where the bracket is located and is movably arranged below the bracket. The support rod controls the movement of the linkage end by pressing against the operating end.

[0012] The push-type lock is connected to the side of the support block away from the linkage end, and the linkage end controls the push-type lock to lock or release the support block by squeezing the support block, thereby opening or closing the movable channel;

[0013] In the unlocked state, the movable channel is open and the support rod is located outside the movable channel; in the locked state, the movable channel is closed and the support rod is located inside the movable channel.

[0014] In a preferred embodiment of the present invention, a limiting groove is provided on the support block, and the support rod is located in the limiting groove in the locked state.

[0015] In a preferred embodiment of the present invention, the operating end and the linkage end form an angle smaller than 180° on the side where the movable channel is located.

[0043] Example 1

[0044] The present embodiment provides a locking mechanism 64 of a movable connection, comprising a bracket 1, a travel switch 2, a support block 3, a push-type lock 4, and a support rod 5; the movable connection component of the present embodiment is a connecting rod;

[0045] The bracket 1 is used to fix the locking mechanism 64 to the side of the connecting rod;

[0046] The travel switch 2 includes an operating end 21 and a linkage end 22, wherein the linkage end 22 is located below the operating end 21;

[0047] The support block 3 is pivotally connected to the bracket 1 , and the support block 3 is arranged within the travel distance of the linkage end 22 and forms a movable channel 71 with the linkage end 22 ;

[0048] The two ends of the support rod 5 are fixed to the connecting rod. In the initial state, the rod body of the support rod 5 passes through the bottom of the bracket 1 and is arranged at the opening below the movable channel 71. When the connecting rod moves, it drives the support rod 5 in and out of the movable channel 71. The support rod 5 controls the movement of the linkage end 22 by pressing against the operating end 21.

[0049] The push-type lock buckle 4 is connected to the side of the support block 3 away from the linkage end 22. The linkage end 22 controls the push-type lock buckle 4 to lock or release the support block 3 by squeezing the support block 3, and the movable channel 71 is opened or closed;

[0050] In the unlocked state, the movable channel 71 is open, and the support rod 5 is located outside the movable channel 71 ; in the locked state, the movable channel 71 is closed, and the support rod 5 is located inside the movable channel 71 .

[0051] In this embodiment, a limiting groove 31 is provided on the support block 3 , and the support rod 5 is located in the limiting groove 31 in the locked state.

[0052] The bracket 1 includes a fixing plate 11, a housing 12, and an end plate 13. The fixing plate 11 is fixed to the mounting surface of the connecting rod. The travel switch 2 is pivotally connected to the housing 12. The push-type lock 4 and the support block 3 are arranged on the end plate 13. The bottom of the support block 3 is pivotally connected to the lower edge of the end plate 13. The push-type lock 4 is fixed to the end plate 13. A return spring 41 is provided between the side wall of the support block 3 and the end plate 13.

[0053] In this embodiment, the movable channel 71 is formed in the housing 12, and an opening is provided at the bottom of the housing 12 to communicate with the movable channel 71. A clearance groove 72 is provided at the top of the movable channel 71, and the operating end 21 is located at the same height as the clearance groove 72. The operating end 21 and the linkage end 22 form an angle of less than 180° on the side where the movable channel 71 is located.

[0054] The locking mechanism 64 of this embodiment is similar to Figure 12 A connecting rod assembly 63 is formed by a connecting rod combination, such as Figure 2 , comprising two parallel sets of connecting rods, the locking mechanism 64 is disposed between the two sets of connecting rods, and the support rod 5 is mounted on at least one of the connecting rods. In this embodiment, the support rod 5 is mounted at the bend of the bending connecting rod 51. For stability, the support rod 5 can pass through the housing 12 of the locking mechanism 64, connecting the two sets of connecting rods and acting as a synchronization rod to ensure the consistency of the movement of the two sets of connecting rods.
