Description

Technical Field

[0001] The utility model relates to the technical field of key switches, in particular to a light-shielding structure for silica gel keys. Background Art

[0002] Many electronic devices are provided with function keys on their shells. For example, in a video switcher, there are several silica gel keys on it. At the same time, in order to facilitate operation and improve the appearance of the product, in the existing key structure, a lighting component is usually arranged in the key cap. The lighting component includes a lighting component and a switch. When the key cap is pressed, the key cap contacts the switch, causing the lighting component to emit light.

[0003] Although the keys provided on the existing video switcher can emit light, enabling customers to easily control the video switcher, there are still some deficiencies. For keys on the video switcher where two light sources are very close, it is very easy for the unlit silica gel to be contaminated by the light of adjacent keys, which will cause misunderstandings for customers, thinking that the corresponding function has been activated. Therefore, a light-shielding structure for silica gel keys is proposed to solve the above problems. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a light-shielding structure for silica gel keys, aiming to improve the problem that in the prior art, for keys on a video switcher where two light sources are very close, it is very easy for the unlit silica gel to be contaminated by the light of adjacent keys, which will cause misunderstandings for customers, thinking that the corresponding function has been activated.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A light-shielding structure for silica gel keys, including a first housing, a second housing, and a plurality of keys. The second housing is located above the first housing. A connecting member is arranged between the first housing and the second housing. A plurality of the keys are all slidably connected between the first housing and the second housing. A fixed block is fixedly connected to the middle of the first housing. A positioning pin is fixedly connected to the bottom of the second housing. The fixed block and the positioning pin are in plug-in fit. A housing is slidably connected to the middle of the first housing. A mounting plate is fixedly connected to the outside of the housing. A screw is slidably connected to the middle of the mounting plate. A first compression spring is fixedly connected to the inside of the housing. The other end of the first compression spring is fixedly connected to a light-shielding strip. The light-shielding strip is slidably connected to the middle of the housing and the second housing. A limiting component is fixedly connected to the inside of the housing;

[0006] Through the above technical solution, the housing and the mounting plate can be fixed inside the first sleeve by using screws. At this time, under the action of the connecting component, the first sleeve and the second sleeve can be quickly connected and fixed. The light-blocking strip can block the light generated by the keys, thereby avoiding light pollution between adjacent keys. At the same time, when the light-blocking strip is squeezed, it will move downward and compress the first compression spring. When there is no external force squeezing the light-blocking strip, the light-blocking strip can be reset under the action of the first compression spring, thereby continuously blocking the light generated by the keys and avoiding the influence of the presence of the light-blocking strip on the user's use.

[0007] Further, the limiting component includes a partition plate, the partition plate is slidably connected inside the housing, and the partition plate is fixedly connected between the first compression spring and the light-blocking strip;

[0008] Through the above technical solution, the partition plate can prevent the problem that the light-blocking strip is separated from the housing when moving, and can make the light-blocking strip slide smoothly in the middle of the housing.

[0009] Further, the connecting component includes a first mounting block, the first mounting block is fixedly connected to the outside of the second sleeve, a positioning block is fixedly connected to the bottom of the first mounting block, a second mounting block is fixedly connected to the outside of the first sleeve, the positioning block and the second mounting block are inserted and matched, a second compression spring is fixedly connected to the inside of the second mounting block, the other end of the second compression spring is fixedly connected to a clamping block, the clamping block is in contact with the positioning block, a clamping groove is formed in the middle of the positioning block, and the clamping block and the clamping groove are inserted and matched. A disassembly component is rotatably connected to the middle of the second mounting block;

[0010] Through the above technical solution, by inserting the positioning block into the second mounting block, when the positioning block enters, it will squeeze the clamping block and make the clamping block compress the second compression spring. At this time, the first sleeve and the second sleeve can be connected. When the clamping groove moves to the original position of the clamping block, the clamping block can be ejected into the clamping groove under the action of the second compression spring, thereby quickly connecting and fixing the first sleeve and the second sleeve.

[0011] Further, the disassembly component includes a rotating rod, the rotating rod is rotatably connected to the middle of the second mounting block, a winding wheel is fixedly connected to one end of the rotating rod close to the second mounting block, a pulling rope is fixedly connected to the middle of the winding wheel, and the other end of the pulling rope is fixedly connected to the side of the clamping block close to the clamping groove;

[0013] Further, a positioning groove is formed in the middle of the fixing block, and the positioning pin and the positioning groove are inserted and matched;

[0014] Through the above technical solution, the positioning pin can be limited by the positioning groove, so as to facilitate the connection of the first housing and the second housing, and at the same time improve the installation speed of the first housing and the second housing.

[0015] Furthermore, a groove is formed in the middle of the second mounting block, and the positioning block is inserted and matched with the groove;

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, the light generated by the key can be blocked by the light-shielding strip, so as to avoid the light pollution of adjacent keys.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a light-shielding structure for a silicone button, including a first housing 1, a second housing 7 and a plurality of buttons 9. The second housing 7 is located above the first housing 1. A connecting member is provided between the first housing 1 and the second housing 7. The plurality of buttons 9 are all slidably connected between the first housing 1 and the second housing 7. A fixed block 2 is fixedly connected to the middle of the first housing 1. A positioning pin 8 is fixedly connected to the bottom of the second housing 7. The fixed block 2 and the positioning pin 8 are inserted and matched. A positioning groove 20 is opened in the middle of the fixed block 2. The positioning pin 8 and the positioning groove 20 are inserted and matched. The positioning pin 8 can be limited by the positioning groove 20, so that the first housing 1 and the second housing 7 can be quickly aligned and connected, and the assembly speed between the first housing 1 and the second housing 7 can be improved.

[0033] Refer to Figures 1 - 3, a housing 3 is slidably connected to the middle of the first housing cover 1. An installation plate 6 is fixedly connected to the outside of the housing 3. A screw is slidably connected to the middle of the installation plate 6. By using the screw, the installation plate 6 can be installed, and then the housing 3 can be fixed. A first compression spring 4 is fixedly connected to the inside of the housing 3. The other end of the first compression spring 4 is fixedly connected to a light-shielding strip 5. The light-shielding strip 5 is slidably connected to the middle of the housing 3 and the second housing cover 7. The light-shielding strip 5 can block between two adjacent buttons 9, preventing the problem of light pollution. At the same time, when the light-shielding strip 5 is squeezed, the first compression spring 4 can be compressed and move downward. When the pressure on the light-shielding strip 5 disappears, under the action of the first compression spring 4, the light-shielding strip 5 can be reset, thus avoiding the influence of the presence of the light-shielding strip 5 on the user when using the button 9. A limiting component is fixedly connected to the inside of the housing 3.

[0034] Refer to Figure 3 , the limiting component includes a partition 10. The partition 10 is slidably connected to the inside of the housing 3. The partition 10 is fixedly connected between the first compression spring 4 and the light-shielding strip 5. The partition 10 can limit the light-shielding strip 5, so that the light-shielding strip 5 can only slide in the middle of the housing 3, preventing the problem that the light-shielding strip 5 is separated from the housing 3. At the same time, it can avoid the situation that the light-shielding strip 5 is inclined when moving, preventing the problem that the first compression spring 4 is deformed and damaged due to the inclined extrusion of the light-shielding strip 5, and improving the service life of the first compression spring 4.

[0035] Refer to Figure 4 and Figure 5 , the connection component includes a first installation block 11. The first installation block 11 is fixedly connected to the outside of the second housing cover 7. A positioning block 12 is fixedly connected to the bottom of the first installation block 11. A second installation block 13 is fixedly connected to the outside of the first housing cover 1. The positioning block 12 and the second installation block 13 are inserted and matched. A groove 21 is formed in the middle of the second installation block 13. The positioning block 12 and the groove 21 are inserted and matched. The groove 21 can provide a position for the positioning block 12 to enter, and at the same time, it can ensure that the positioning block 12 can enter the specified position for connection work. A second compression spring 14 is fixedly connected to the inside of the second installation block 13. The other end of the second compression spring 14 is fixedly connected to a clamping block 15. The clamping block 15 is in contact with the positioning block 12. A clamping groove 16 is formed in the middle of the positioning block 12. The clamping block 15 and the clamping groove 16 are inserted and matched. The side of the clamping block 15 close to the positioning block 12 is provided with an arc.

[0036] Refer to Figure 4 and Figure 5, when the positioning block 12 enters the groove 21, the positioning block 12 will contact the clamping block 15. At this time, the arc-shaped design enables the positioning block 12 to squeeze the clamping block 15 and make the clamping block 15 move. When the clamping block 15 moves, the second compression spring 14 can be compressed, and at the same time, the clamping block 15 can be retracted into the second mounting block 13. At this time, the positioning block 12 can completely enter the groove 21. When the card slot 16 moves to the original position of the clamping block 15 and the clamping block 15 is not externally extruded, under the action of the second compression spring 14, the clamping block 15 can be ejected into the card slot 16, thereby connecting the first housing 1 and the second housing 7. The middle part of the second mounting block 13 is rotatably connected with a disassembly component.

[0037] Refer to Figure 5 , the disassembly component includes a rotating rod 17. The rotating rod 17 is rotatably connected to the middle part of the second mounting block 13. One end of the rotating rod 17 close to the second mounting block 13 is fixedly connected with a winding wheel 18. The middle part of the winding wheel 18 is fixedly connected with a pulling rope 19. The other end of the pulling rope 19 is fixedly connected to one side of the clamping block 15 close to the card slot 16. By rotating the rotating rod 17, the winding wheel 18 can be rotated. When the winding wheel 18 rotates, the pulling rope 19 can be wound. While the pulling rope 19 is being wound, the end of the pulling rope 19 away from the winding wheel 18 will pull the clamping block 15 out of the middle of the card slot 16, thereby releasing the restriction on the positioning block 12. At this time, the first housing 1 and the fixed block 2 can be separated, and at this time, it is convenient to disassemble the mounting plate 6 and maintain or replace the light-shielding part. The end of the rotating rod 17 away from the second mounting block 13 is fixedly connected with a handle. The outer side of the handle is provided with an anti-slip groove. Through the handle and the anti-slip groove, the rotating rod 17 can be rotated more effectively and comfortably.

[0038] Working principle: When in use, the housing 3 is inserted into the first housing 1 and the mounting plate 6 is fixed with screws, so that the housing 3 can be fixed in the first housing 1. At this time, after the first housing 1 and the second housing 7 are connected, a complete video switcher can be assembled. By pressing one of the buttons 9, the light-shielding belt 5 can be lowered simultaneously, thereby preventing the light-shielding belt 5 from affecting the user's feel. At the same time, when the housing 3 moves downward, the first compression spring 4 can be compressed, and after the button 9 rebounds, the light-shielding belt 5 can be reset by the first compression spring 4, thereby blocking the light beam emitted by the button 9 and preventing the light beam emitted by the button 9 from affecting the unused button 9 close to it. At the same time, under the action of the partition 10, the light-shielding belt 5 can be limited, thereby preventing the problem that the light-shielding belt 5 separates from the housing 3 during movement, and enabling the light-shielding belt 5 to slide smoothly in the middle of the housing 3;

[0039] By inserting the positioning block 12 into the mounting block two 13, when the positioning block 12 enters, it will squeeze the clamping block 15 and compress the second compression spring 14 by the clamping block 15. When the card slot 16 moves to the original position of the clamping block 15, the clamping block 15 can be ejected into the card slot 16 under the action of the second compression spring 14, so that the first housing 1 and the second housing 7 can be quickly connected and fixed. By rotating the rotating rod 17 and winding the pulling rope 19 under the action of the winding wheel 18, the clamping block 15 and the card slot 16 can be separated at this time, so that the connection between the first housing 1 and the second housing 7 can be quickly released. At this time, the first housing 1 and the second housing 7 can be quickly separated, so that the mounting plate 6 can be easily disassembled and the light-shielding part can be maintained or replaced.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
