DETAILED DESCRIPTION

[0027] The utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0028] In this embodiment, refer to Figures 1-9 The specific implementation of the smooth sliding key switch includes a shell 1 and a slidable shaft core 2. The lower end of the shaft core 2 is provided with a return spring 3 matched with the shell 1. One side of the shaft core 2 is provided with a guide block 4 which is slidably matched with the shell 1 through a first guide assembly. The shaft core 2 slides more smoothly in the shell 1, avoiding shaking and deviation during the sliding process. The key switch can complete the operation instruction stably and quickly, thereby improving the accuracy and use experience of the key switch. The key switch can be applied to short shafts, conventional shafts on a keyboard and machine tool buttons and other devices requiring precise operation.

[0029] Further, the first guide assembly includes a through slot 4A and a limiting stop 5. The through slot 4A is arranged on both sides of the guide block 4, and the limiting stop 5 is arranged on one side of the shell 1. The size of the through slot 4A is matched with the size of the limiting stop 5. Through the close cooperation of the through slot 4A and the limiting stop 5, the shaft core 2 can slide stably and smoothly while avoiding deviation or shaking. The accuracy and stability of the key switch are ensured, thereby improving the use experience of the user. The key switch is prevented from being stuck during the sliding process, avoiding unnecessary loss to the user.

[0030] Further, the guide block 4 is in a T-shaped structure. The T-shaped structure makes the contact area of the guide block 4 and the limiting stop 5 larger, thereby enhancing the friction between the guide block 4 and the limiting stop 5 and making the shaft core 2 more stable during the sliding process. In addition, the T-shaped guide block 4 also has a guiding effect, which can guide the shaft core 2 to move along the predetermined trajectory during the sliding process, further avoiding deviation or shaking. At the same time, the T-shaped guide block 4 is relatively simple in design and manufacture, facilitating mass production and application, reducing production cost and improving market competitiveness of the product.

[0031] Further, the guide block 4 is integrally formed on one side of the shaft core 2. The integrated design makes the connection between the guide block 4 and the shaft core 2 more secure, less likely to loosen or fall off, thereby further improving the stability and durability of the key switch. This design reduces the gap between parts, avoids the problem of loosening caused by long-term use or external force, and ensures the continuity and accuracy of the shaft core 2 during sliding.

[0032] Further, a second guide assembly is provided between the shaft core 2 and the housing 1. The second guide assembly assists the shaft core 2 and the housing in sliding fit, making the sliding of the shaft core 2 in the housing 1 more smooth and accurate.

[0033] Further, the second guide assembly includes sliding grooves 9 and sliding blocks 8 provided on both sides of the housing 1 and the shaft core 2, respectively. Through the cooperation of the sliding blocks 8 and the sliding grooves 9, the smoothness of the key switch is enhanced, and the stability and reliability of its operation are improved. The precise cooperation of the sliding blocks 8 and the sliding grooves 9 ensures that the shaft core 2 moves smoothly and stably while sharing the impact force between the guide block 4 and the limiting stop edge 5, avoiding the deformation caused by the violent collision or extrusion between the guide block 4 and the limiting stop edge 5 when subjected to external impact, thereby prolonging the service life of the key switch.

[0034] Further, a magnet 6 is embedded at the lower end of the shaft core 2, and the housing 1 is provided with a ring groove 7 or a through hole corresponding to the magnet 6. The magnet 6 is used to form a Hall switch with the external connection. The design of the ring groove 7 or the through hole makes the magnetic field interaction between the magnet 6 and the external device more smooth, ensuring the accuracy and stability of the Hall switch. In this embodiment, the ring groove 7 design is adopted, which improves the sealing of the housing 1 without affecting the magnetic field induction between the magnet 6 and the external device.

[0035] Further, a recess 10 is provided at the upper end of the shaft core 2, and a cross key block 11 is provided in the recess 10. The cross key block 11 or the recess 10 is connected and matched with the key cap or other operating components, and can be detachably installed on the shaft core 2. Therefore, users can stably connect different types of key caps or operating components with the shaft core 2 according to personal habits or operating needs. This design not only improves the versatility and flexibility of the key switch, but also allows users to customize it individually to meet the use requirements in different scenarios.

[0036] Further, the shell 1 is composed of the upper cover 1A and the base 1B, and the upper cover 1A and the base 1B are respectively provided with buckles 12 and clamping blocks 13 for mutual cooperation. The buckles 12 are provided with through grooves matched with the clamping blocks 13. The design of the upper cover 1A and the base 1B makes the processing of the shell 1 more convenient, and improves the overall strength and stability of the shell 1. The ingenious combination of the clamping blocks 13 and the buckles 12 simplifies the assembly process and ensures accurate positioning and stable connection of the shell 1 during assembly. This design not only improves production efficiency, but also reduces performance problems caused by improper assembly.

[0037] Further, the upper end of the buckle 12 is provided with a guide structure 14 matched with the clamping block 13. The guide structure 14 ensures that the upper cover 1A can be smoothly and accurately docked with the base 1B during installation, avoiding damage or loosening caused by position deviation or improper installation force. When the upper cover 1A is installed above the base 1B, the guide structure 14 pushes the buckle 12 to deform slightly outward, and the buckle 12 resets after installation, so that the through groove cooperates with the clamping block 13 to fix the upper cover 1A.

[0038] Further, the lower end of the shell 1 is provided with a guide column 15 for positioning and installation. The design of the guide column 15 makes the installation steps of the key switch more convenient and fast. Only the guide column 15 needs to be aligned with the corresponding mounting hole and inserted, and the installation steps of the key switch can be quickly completed.

[0039] Further, the shell 1 is provided with a light guide plate 16 at one end, and the light guide plate 16 is provided with a fixed stop edge 17 matched with the shell 1 at one end. The light guide plate 16 can transmit the light at the lower end of the key switch to the upper end of the key switch. The design of the limiting stop edge 5 makes the installation of the light guide plate 16 more convenient and fast. Only the light guide plate 16 needs to be inserted into the corresponding hole, and the light guide plate 16 is firmly fixed in the shell 1 through the cooperation of the base 1B and the upper cover 1A.

[0040] The beneficial effects of the utility model are: the first guide assembly makes the guide block 4 and the shell 1 slide together, so that the shaft core 2 slides more smoothly in the shell 1, avoiding shaking and deviation of the shaft core 2 during sliding. The key switch can stably and quickly complete the operation instruction, thereby improving the accuracy and use experience of the key switch.
