[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] The embodiments described with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and cannot be understood as limiting the present application. In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meanings of "several" and "multiple" are two or more, unless otherwise clearly and specifically defined. In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. In this application, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature can include the first and second features being in direct contact, or it can include the first and second features not being in direct contact but being in contact through another feature between them. Moreover, the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature being directly above and obliquely above the second feature, or simply means that the first feature is lower in level than the second feature.

[0019] See also Figure 1-5The keyboard with an annular gasket specifically implemented includes a bottom shell 1, a key 2, a top shell 3, a positioning plate 4 and a PCB board 5. The key 2, the positioning plate 4 and the PCB board 5 are sequentially connected and arranged in the bottom shell 1. The key 2 is arranged on the surface of the positioning plate 4, and the axial end of the key 2 passes from the positioning plate 4 to the PCB board 5. The positioning plate 4 and the PCB board 5 are fixedly connected. The top shell 3 is arranged on the top of the bottom shell 1. The top shell 3 and the bottom shell 1 are connected by screws to cover the key 2. The bottom shell 1 is provided with an annular gasket 6. The PCB board 5 is arranged on the annular gasket 6. When the PCB board 5 is pressed by the key 2, the annular gasket 6 It can rebound, so that the user has an elastic experience when using it. A groove 13 is provided on the inner wall of the bottom shell 1, and an elastic ring 7 is installed between the positioning plate 4 and the PCB board 5. The surface of the elastic ring 7 is embedded in the groove 13. The setting of the groove 13 is used to clamp the elastic ring 7. When the button 2 is pressed, the distance is short, so the elastic ring 7 does not slide relatively on the inner wall of the groove 13. Therefore, when the inner side of the elastic ring 7 between the positioning plate 4 and the PCB board 5 moves downward with the button 2, the surface of the elastic ring 7 on the inner wall of the groove 13 pulls back the inner side of the elastic ring 7, that is, the elastic ring 7 rebounds, further improving the user's elastic experience when using it.

[0020] Specifically, the elastic ring 7 is made of silicone. The present application does not limit the material of the elastic ring 7, and it can be reasonably changed under the premise that the elasticity meets the standard.

[0021] In this embodiment, the bottom surface of the PCB board 5 is provided with fastening nails 8 , and the fastening nails 8 are inserted into the positioning plate 4 from the PCB board 5 in sequence, and the fastening nails 8 are screwed to tighten the PCB board 5 and the positioning plate 4 .

[0022] Specifically, a matching block 9 is provided at the lower end of the positioning plate 4, and the matching block 9 is integrated with the positioning plate 4. The positioning plate 4 is a hard plastic plate. The matching block 9 and the positioning plate 4 are injection molded together. The present application does not limit the connection relationship between the matching block 9 and the positioning plate 4. A matching hole 10 is provided at the bottom end of the matching block 9, and a fastening cylinder 11 is provided at the matching hole 10. A tooth-shaped stripe 12 is provided on the surface of the fastening block. The fastening nail 8 is screwed into the fastening cylinder 11. When the fastening nail 8 is screwed into the fastening cylinder 11, the fastening cylinder 11 is stretched open, so that the tooth-shaped stripe 12 tightly grasps the matching block 9, so that the PCB board 5 and the positioning plate 4 are connected more tightly.

[0023] In this embodiment, a buffer plate 14 is provided between the positioning plate 4 and the PCB board 5. The provision of the buffer plate 14 further improves the elasticity experience of the user during use.

[0024] Specifically, the buffer plate 14 is made of filled foam. The present application does not limit the material of the elastic ring 7, and it can be reasonably changed under the premise of meeting the elasticity requirements.
