Abstract
Description
Technical Field
[0001] The utility model relates to a quick-detachable structure of an intelligent toilet cover. Background Art
[0002] There are many kinds of quick-release structures for existing smart toilet seat covers (including upper covers and seat rings), which can be divided into two categories according to whether the rotating shaft is limited or not, and can be divided into two categories: locking shaft function and non-locking shaft function. Although the quick-release structure without the locking shaft function has fewer parts, a simple structure, and low cost, the cover is not firmly connected to the rotating shaft, and the cover is easy to detach during normal use, making it unstable to use. For example, the quick-release device for the toilet seat cover disclosed in the utility model patent with authorization announcement number CN217218877U has a disassembly slot on the shaft sleeve seat at the rear end of the seat cover. As long as the seat cover is opened to the set angle, the rotating shaft can freely enter and exit the shaft sleeve seat through the disassembly slot. The quick-release structure with the locking shaft function can effectively prevent the rotating shaft from being limited. The cover cannot detach from the rotating shaft during normal use, but it often needs to be equipped with complex spring lock components inside, which has many parts, a complex structure, and a high manufacturing cost. Utility Model Content
[0003] The utility model provides a quick-release structure for a smart toilet seat cover, which has the function of locking the rotating shaft. At the same time, it has a simple structure and effectively reduces the manufacturing cost, which overcomes the shortcomings of the background technology. The technical solution adopted by the utility model to solve the technical problem is:
[0004] The quick-release structure of the smart toilet cover includes a cover and a rear shell. A rotating shaft joint is provided at the side position of the rear end of the cover, and the rotating shaft joint is provided with a pivot hole. The rear shell is provided with a rotating shaft extending toward the side. The side wall of the rear end of the rotating shaft joint is provided with a mounting notch at least in the part facing the inside so that the inner cavity of the pivot hole can also communicate with the outside through the mounting notch. The limiter also includes a sleeve, which can be axially slidably inserted into the pivot hole. When the sleeve slides toward the outside, the mounting notch is gradually opened. The sleeve gradually closes the installation gap when sliding inward. During installation, the sleeve is slid to open the installation gap, and the end of the rotating shaft enters the pivot hole along the installation gap. When the sleeve is slid inward to close the installation gap, the sleeve covers the end of the rotating shaft, and the rear shell prevents the sleeve from sliding out of the pivot hole. During disassembly, the sleeve is slid outward to open the installation gap, and the sleeve is separated from the end of the rotating shaft, and the end of the rotating shaft exits the pivot hole along the installation gap.
[0005] In a preferred embodiment: a plurality of stress-bearing ribs are arranged on the side wall of the sleeve at intervals along the circumferential direction, the stress-bearing ribs extend axially, and a slot is arranged on the side wall of the pivot hole corresponding to the stress-bearing ribs, and the stress-bearing ribs are slidably inserted into the slot.
[0006] In a preferred embodiment: the limiting member also includes an arc-shaped blocking piece, which extends axially, and the shaft sleeve is located on the inner side of the arc-shaped opening direction of the arc-shaped blocking piece, and the inner side edge of the arc-shaped blocking piece is connected to the inner end position of the shaft sleeve side wall through an extension arm, and a clearance space is formed between the arc-shaped blocking piece and the shaft sleeve, and the clearance space accommodates the side wall of the rear end of the rotating shaft joint when the shaft sleeve opens the installation notch, and the arc-shaped blocking piece covers the installation notch when the shaft sleeve closes the installation notch.
[0007] In a preferred embodiment: two through-slits are provided on the outer portion of the side wall of the sleeve to form an elastic arm between the two through-slits, and the end of the elastic arm protrudes upward to form a buckle, and the buckle is pressed against the end face of the side of the installation notch when the sleeve closes the installation notch.
[0008] In a preferred embodiment, the limiting member is integrally formed.
[0009] In a preferred embodiment, the outer end surface of the pivot hole is a closed surface.
[0010] In a preferred embodiment, the inner end surface of the rotating shaft coupling portion is provided with a flange at the edge of the pivot hole, and the flange abuts against the side of the rear shell.
[0011] In a preferred embodiment, the cover plate is a seat ring.
[0012] In a preferred embodiment, the two rotational connection structures between the cover plate and the rear housing both use quick-release structures.
[0013] In a preferred embodiment: there are two rotating connection structures between the cover plate and the rear shell, one rotating connection structure uses a quick-release structure, and the other rotating connection structure is composed of a damper shaft extending toward the side of the rear shell, and a damper joint arranged at the other side position of the rear end of the cover plate, and the damper shaft is axially inserted into the damper joint.
[0014] Compared with the background technology, this technical solution has the following advantages:
[0015] 1. The sleeve slides within the pivot hole to control the opening or closing of the mounting notch. Opening the notch allows the shaft to enter and exit the pivot hole along the notch, enabling disassembly. Closing the notch traps the shaft, securing the rotational connection between the shaft and the shaft joint. Therefore, during normal use, the shaft and the shaft joint are securely locked together, allowing only relative rotation. The notch can only be opened by manually sliding the shaft axially when disassembly is required. Because the mounting notch only requires modifications to the shaft joint, the sleeve's structure is also very simple. Consequently, the entire quick-release structure has few components, is low-cost, and facilitates assembly and disassembly.
[0016] 2. The adaption and plugging of the stress-bearing ribs and the card slots is different from ordinary guides. If it is just a guide, multiple stress-bearing ribs are not needed. The cooperation between the stress-bearing ribs and the card slots is to transfer the user's gravity borne by the cover to the back shell and the toilet seat, so that the cover is stable during use.
[0017] 3. The inner side of the arc-shaped baffle is connected to the inner side of the sleeve through an extension arm. When the sleeve is slid outward to open the installation gap, the side wall of the rear end of the shaft joint is accommodated in the clearance space. At the same time, the extension arm can be engaged with the end face of the side of the installation gap to prevent the sleeve from sliding out of the pivot hole outward.
[0018] 4. When the sleeve closes the mounting gap, the buckle of the elastic arm on the sleeve presses against the end face of the side of the mounting gap to prevent the sleeve from moving outward. This does not mean that the sleeve will not automatically open the mounting gap without external force or even when the external force is insufficient to push open the buckle. The sleeve can firmly close the mounting gap and the rotating shaft is firmly locked by the sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figures 1 to 7 , a quick-release structure of a smart toilet cover, including a cover 10 and a rear shell 20, with the side facing the user as the front and the side facing the wall as the rear. A rotating shaft joint 12 is provided at the side position of the rear end of the cover 10, and the rotating shaft joint is provided with a pivot hole 14. The rear shell 20 is provided with a rotating shaft 22 extending toward the side, with the inner side facing the center of the cover and the outer side facing the edge of the cover. The side wall of the rear end of the rotating shaft joint 12 is provided with a mounting notch 16 at the inner side so that the inner cavity of the pivot hole 14 can also communicate with the outside through the mounting notch 16, that is, the pivot hole 14 is not only axially open to communicate with the outside world, but also communicates with the outside world through the mounting notch 16 on the side wall. It also includes a limiting member 30, which includes a shaft sleeve 32, which can be axially slidably inserted into the pivot hole 14. When the shaft sleeve 32 slides toward the outside, it gradually opens the mounting notch 16 (such as Figure 5 As shown), the sleeve 32 gradually closes the mounting notch 16 as it slides inward (as shown Figure 6 、 7 As shown). It is understandable that the mounting notch 16 only needs to provide clearance for the rotating shaft 22 to enter and exit the pivot hole 24. Therefore, the mounting notch can also axially penetrate the side wall of the rear end of the rotating shaft coupling portion 12, that is, be opened along the entire axial direction of the side wall of the rear end of the rotating shaft coupling portion 12.
[0029] During installation, the sleeve 32 is slid outward to open the installation notch 16 (if the installation notch axially penetrates the side wall of the shaft joint, the stopper can be removed in advance), and the end of the shaft 22 enters the pivot hole 14 along the installation notch. While the sleeve 32 is slid inward to close the installation notch 16, the sleeve 32 covers the end of the shaft 22. The rear housing 20 blocks the inner side of the sleeve 32, preventing the sleeve from sliding out of the pivot hole 14, thereby restricting the shaft 22 from rotating within the sleeve 32. Those skilled in the art will understand that locking or limiting the shaft means that the shaft is rotatably constrained in the sleeve or pivot hole, that is, the shaft and the shaft joint can only rotate relative to each other but cannot be separated. When disassembly is required, the sleeve 32 is slid outward to open the mounting notch 16 , and the sleeve 32 is separated from the end of the shaft 22 , and the end of the shaft 22 exits the pivot hole 14 along the mounting notch 16 to separate the cover 10 from the rear shell 20 .
[0030] It is understandable that both of the rotational connection structures between the cover plate 10 and the rear housing 20 can use the aforementioned quick-release structure. That is, the left and right rotational shaft joints at the rear end of the cover plate 10 are both removably locked and connected to the rotational shaft on the rear housing 20 via mounting notches and stoppers. Of course, it is also possible that only one of the two rotational connection structures between the cover plate 10 and the rear housing 20 uses a quick-release structure, while the other rotational connection structure uses a conventional pivoting method, allowing the rotational shaft to be directly inserted into the pivot hole. This is because only the mounting notch 16 on one side can provide the clearance space required for assembly. During assembly, the rotational connection structure using the conventional pivoting method is first assembled. Then, after the mounting notch 16 on the quick-release structure side is opened, the rotational shaft 22 can enter the pivot hole 14 via the mounting notch, and finally the shaft sleeve 32 is closed. In addition, the conventional pivoting method can also be a structure as shown in the figure of this embodiment, that is, it is composed of a damper shaft 24 extending toward the side of the rear shell 20, and a damper joint 12a arranged at the other side position of the rear end of the cover 10, and the damper shaft 24 is axially inserted into the damper joint 12a.
[0031] It can be understood that the toilet cover assembly usually includes an upper cover and a seat ring. In this embodiment, the cover 10 corresponds to the seat ring as shown in the accompanying drawings, and the upper cover can also be installed in the same way as the seat ring. As shown in the accompanying drawings, the upper cover 40 is also connected to the rear shell 20, and the upper cover 40 and the rear shell 20 can also be connected using a quick-release structure.
[0032] Preferably, the sidewall of the sleeve 32 is provided with a plurality of stress-bearing ribs 322 at intervals along the circumference. The stress-bearing ribs extend axially. The sidewall of the pivot hole 14 is provided with slots 18 corresponding to the stress-bearing ribs. The stress-bearing ribs 322 are slidably inserted into the slots 18. This embodiment uses three stress-bearing ribs 322.
[0033] Preferably, the shaft sleeve 32 can only slide in and out of the pivot hole from the inside of the pivot hole 14, and the limit member 30 also includes an arc-shaped baffle 34, which extends axially, and the shaft sleeve 32 is located on the inner side of the arc-shaped opening direction of the arc-shaped baffle 34, and the inner side edge of the arc-shaped baffle 34 is connected to the inner end position of the side wall of the shaft sleeve 32 through an extension arm 36, and a clearance space 38 is formed between the arc-shaped baffle 34 and the shaft sleeve 32, and the clearance space 38 accommodates the side wall of the rear end of the rotating shaft joint 12 when the shaft sleeve 32 opens the mounting notch 16. Due to the presence of the extension arm 36, the limit member 30 cannot slide all the way outward, because the end face 162 of the side of the mounting notch 16 will block the extension arm 36, so the shaft sleeve can only be assembled from the inside. The arc-shaped blocking piece 34 covers the side wall at the rear end of the shaft coupling portion 12 and the mounting notch when the shaft sleeve 32 closes the mounting notch 16 .
[0034] Preferably, the sidewall of the sleeve 32 is provided with two through-slits 324 on the outer portion thereof, thereby forming an elastic arm 326 between the two through-slits. The ends of the elastic arms protrude upward to form a buckle 328. When the sleeve 32 closes the mounting notch 16, the buckle 328 presses against the end surface 162 of the mounting notch. Therefore, during removal, when an external force pushes on the sleeve, the buckle 328 and the elastic arm 326 must be displaced inwardly by the obstruction of the end surface 162, and the sleeve can slide.
[0035] Preferably, the limiting member 30 is integrally formed.
[0036] Preferably, the outer end surface of the pivot hole 14 is a closed surface, so that the sleeve 32 can only slide into and out of the pivot hole 14 from the inner side of the pivot hole 14, that is, it cannot be removed from the pivot hole toward the outside. Therefore, the sleeve 32 cannot be removed from the outside of the pivot hole 14 either.
[0037] Preferably, a protrusion 121 is provided on the inner end surface of the rotating shaft coupling portion 12 at the edge of the pivot hole 14 , and the protrusion 121 abuts against the side of the rear housing 20 .
[0038] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
