Description

Technical Field

[0002] The keyboard is a common input tool in computers and electronic devices, used to input characters, numbers, symbols and instructions into the device.

[0003] Some keyboards use a metal plate as the keyboard base. The square metal plate used as the keyboard base needs to be bent during processing. This process usually requires a stamping machine and matching molds. The metal plate is placed on a lower mold, and then the upper mold is lowered by the stamping mechanism, causing the plate between the two molds to bend and deform according to the mold shape. However, when bending the keyboard base, workers often place the base on the lower mold. To prevent significant deviations in the bending position that could affect subsequent use, the plate's position needs to be carefully adjusted, which is quite inconvenient. Therefore, a keyboard base bending and positioning mechanism is proposed. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figures 1-5As shown, this embodiment proposes a keyboard base plate bending and positioning mechanism, including a frame 1; a support platform 12 is fixedly connected to the middle of the frame 1; two pairs of moving rods 13 are slidably connected to the bottom of the support platform 12; a connecting rod 14 is fixedly connected to the top of the moving rods 13; a top rod 15 is installed on the top of the connecting rod 14; a plurality of first elastic ropes 16 are fixedly connected to the bottom of the support platform 12; the other ends of the plurality of first elastic ropes 16 are respectively fixedly connected to the side walls of the plurality of moving rods 13; a circular block 17 is rotatably connected to the bottom of the support platform 12; a ring is fixedly connected to the middle of the circular block 17. Gear 18; A rack 19 is slidably connected to the bottom of the support platform 12; the rack 19 and gear 18 are meshed; a second elastic rope 110 is installed between each pair of moving rods 13; the second elastic rope 110 passes through the middle of the circular block 17; multiple limiting mechanisms are installed at the bottom of the support platform 12; during operation, the lower die for stamping and bending is bolted onto the support platform 12, and then the square metal sheet to be stamped is placed on the lower die. At this time, the square metal sheet is approximately positioned between multiple push rods 15, and the rack 19 is pulled through... The engagement of rack 19 and gear 18 drives the circular block 17 to rotate, causing a pair of second elastic ropes 110 to wind around the center of the circular block 17 and gradually tighten. The gradually tightening second elastic ropes 110 pull a pair of moving rods 13 towards the circular block 17, thereby driving multiple push rods 15 to move. The moving push rods 15 push the metal sheet towards the correct processing position. When the metal sheet reaches the processing position, a limiting mechanism blocks the moving rods 13, making it difficult for the moving rods 13 and push rods 15 to continue moving, preventing the push rods 15 from... 5. If the metal plate that has been positioned is bent or lifted during the continued movement, after the metal plate is positioned, the rack 19 is pushed back, and the second elastic rope 110 is gradually unwound and relaxed. At this time, the first elastic rope 16 will pull the moving rod 13 to move the push rod 15 away from the metal plate that has been positioned. With the above structure, after the square plate that needs to be stamped and bent is placed on the mold, the multiple push rods 15 can be quickly pushed to the designated position by pulling the rack 19, thereby completing the rapid positioning of the square plate.

[0028] like Figure 3 and Figure 4As shown, the limiting mechanism includes a fixed plate 2, an adjusting bolt 21, a movable plate 22, and a protrusion 23. The fixed plate 2 is fixedly connected to the bottom of the support platform 12; the adjusting bolt 21 is threadedly connected to the middle of the fixed plate 2; the movable plate 22 is slidably connected to the middle of the fixed plate 2; one end of the movable plate 22 is rotatably connected to the middle of the adjusting bolt 21; the protrusion 23 is fixedly connected to the other end of the movable plate 22. During operation, after completing the stamping and bending of a batch of square plates, if the size of the next batch of square plates to be stamped and bent changes, the adjusting bolt 21 can be rotated to change the relative position between the adjusting bolt 21 and the fixed plate 2, thereby adjusting the position of the movable plate 22 and the protrusion 23. The position is adjusted so that the moving rod 13 stops when it moves toward the round block 17 due to the obstruction of the protrusion 23. Since the second elastic rope 110 is elastically set, when one moving rod 13 stops due to the obstruction of the protrusion 23, the other moving rods 13 can still move as the second elastic rope 110 is tightened until all the moving rods 13 are blocked by the protrusion 23. By adjusting the position of the multiple protrusions 23, the multiple push rods 15 can push the square metal plate to the corresponding position when they stop. Through the above structure, the stopping position of the multiple moving rods 13 can be easily adjusted, so that the device can position square plates of different sizes and improve the ease of use of the device.

[0029] like Figure 5 and Figure 6 As shown, a screw 3 is fixedly connected to the top of the connecting rod 14; a nut 31 is threadedly connected to the middle of the screw 3; a sleeve 32 is sleeved on the middle of the screw 3; a push rod 15 is fixedly connected to the middle of the sleeve 32; a guide plate 33 is fixedly connected inside the sleeve 32; the guide plate 33 is slidably connected to the middle of the screw 3; during operation, when the lower mold installed on the support platform 12 is replaced with a mold of different height, the height of the sleeve 32 can be adjusted by rotating the nut 31, thereby adjusting the height of multiple push rods 15, so that the bottom of the push rod 15 is higher than the top of the lower mold by no more than the thickness of the plate being stamped. Through the above structure, the height of multiple push rods 15 can be adjusted according to the height of the lower mold, further improving the applicability of the device.

[0030] like Figure 5 and Figure 6As shown, a through groove 4 is provided in the middle of the screw 3; a fall arrestor plate 41 is detachably installed in the middle of the through groove 4; during operation, after adjusting the height of the screw 3 by rotating the nut 31, a fall arrestor plate 41 is inserted into the through groove 4 from below the nut 31. The height of the fall arrestor plate 41 is the height of the bottom of the adjusted nut 31 from the bottom of the through groove 4. Such fall arrestor plates 41 of corresponding height can be easily processed in the workshop, and a batch of fall arrestor plates 41 of corresponding height can be made in advance according to the height dimensions of commonly used lower molds. After the fall arrestor plate 41 of corresponding height is inserted into the fall arrestor plate 41 from below the nut 31, as long as the fall arrestor plate 41 does not come off from the through groove 4, the nut 31 is unlikely to loosen and fall due to equipment vibration, so that the height of the push rod 15 will not easily drop. Through the above structure, after adjusting the height of the push rod 15 by rotating the nut 31, the nut 31 will not easily loosen and fall due to equipment vibration, thereby reducing the occurrence of the push rod 15 hitting the mold and non-metal plate due to the drop in height of the push rod 15.

[0031] like Figure 5 As shown, a fixing tube 5 is fixedly connected to the side wall of the moving rod 13; a connecting buckle 51 is fixedly connected to the end of the second elastic rope 110; the connecting buckle 51 is C-shaped and made of metal; during operation, when it is necessary to connect the second elastic rope 110 to the moving rod 13, the two ends of the connecting buckle 51 are moved to the two ends of the fixing tube 5, and then the connecting buckle 51 is deformed with the help of tools such as pliers. After deformation, the two ends of the connecting buckle 51 are inserted into the fixing tube 5 and are difficult to remove, thus completing the connection between the second elastic rope 110 and the moving rod 13. When the second elastic rope 110 breaks due to repeated use over a long period of time, the connecting buckle 51 can be pried open with tools to remove the two ends of the connecting buckle 51 from the fixing tube 5 to complete the disassembly of the second elastic rope 110. Through the above structure, the second elastic rope 110 can be easily disassembled and assembled, so as to facilitate the replacement of the damaged second elastic rope 110.

[0032] like Figure 6 As shown, a pair of rubber pads 6 are fixed inside the through groove 4; the fall arrestor plate 41 is located between the pair of rubber pads 6; when the fall arrestor plate 41 is inserted into the through groove 4, the fall arrestor plate 41 will be squeezed by the pair of rubber pads 6 and generate a large friction between the rubber pads 6, making it difficult for the fall arrestor plate 41 to leave the through groove 4. Through the above structure, the fall arrestor plate 41 will not easily leave the through groove 4, thereby reducing the occurrence of the drop in height of the top rod 15 after the fall arrestor plate 41 leaves.

[0033] like Figure 5 and Figure 6As shown, a reinforcing plate 7 is fixedly connected to the top of the ejector pin 15; the end of the reinforcing plate 7 is fixedly connected to the middle of the sleeve 32; through the above structure, the occurrence of the end of the ejector pin 15 away from the sleeve 32 being lower than the end of the ejector pin 15 near the sleeve 32 can be reduced, thereby reducing the occurrence of the end of the ejector pin 15 hitting the mold side wall and non-metallic plate when moving.

[0034] Specifically, in use, the keyboard base plate bending and positioning mechanism works as follows: The lower die for stamping and bending is bolted onto the support platform 12. Then, the square metal sheet to be stamped is placed on the lower die, positioned approximately between the multiple push rods 15. Pulling the rack 19, through the engagement of the rack 19 and gear 18, rotates the circular block 17, causing a pair of second elastic ropes 110 to wind around the center of the circular block 17 and gradually tighten. The gradually tightening second elastic ropes 110 pull a pair of moving rods 13 towards the circular block 17, thereby moving the multiple push rods 15. The moving push rods 15 then push the metal sheet towards the correct processing position (e.g., ...). Figure 2 and Figure 3 As shown), after the metal sheet moves to the processing position, the limiting mechanism will block the moving rod 13, making it difficult for the moving rod 13 and the push rod 15 to continue moving, in order to prevent the push rod 15 from bending or lifting the already positioned metal sheet if it continues to move (as shown). Figure 5 As shown), after the metal sheet is positioned, the rack 19 is pushed back, and the second elastic rope 110 is gradually unwound and relaxed. At this time, the first elastic rope 16 will pull the moving rod 13 to move the top rod 15 away from the positioned metal sheet. After completing the stamping and bending of a batch of square plates, if the size of the next batch of square plates to be stamped and bent changes, the adjusting bolt 21 can be rotated to change the relative position between the adjusting bolt 21 and the fixed plate 2, thereby adjusting the position of the moving plate 22 and the protrusion 23. By adjusting the position of the protrusion 23, the moving rod 13 is stopped by the protrusion 23 when it moves towards the round block 17 (e.g.). Figure 2 and Figure 3As shown), since the second elastic rope 110 is elastically set, when one moving rod 13 is stopped by the protrusion 23, the other moving rods 13 can still move as the second elastic rope 110 is tightened, until all moving rods 13 are blocked by the protrusion 23. By adjusting the position of the multiple protrusions 23, the multiple push rods 15 can push the square metal plate to the corresponding position when they stop. When the lower mold installed on the support platform 12 is replaced with a mold of different height, the height of the sleeve 32 can be adjusted by rotating the nut 31, thereby adjusting the height of the multiple push rods 15 so that the bottom of the push rod 15 is higher than the top of the lower mold by no more than the thickness of the plate being stamped. After adjusting the height of the screw 3 by rotating the nut 31, a fall arrestor 41 is inserted into the through groove 4 from below the nut 31 (e.g. Figure 2 , Figure 3 and Figure 4 As shown), the height of the fall arrestor plate 41 is the height of the bottom of the adjusted nut 31 from the bottom of the through groove 4. Fall arrestor plates 41 of this corresponding height can be easily manufactured in the workshop, and a batch of fall arrestor plates 41 of the corresponding height can be pre-made according to the height dimensions of commonly used lower molds. After inserting the fall arrestor plate 41 of the corresponding height from below the nut 31, as long as the fall arrestor plate 41 does not detach from the through groove 4, the nut 31 is unlikely to loosen and fall due to equipment vibration, thus preventing the height of the push rod 15 from easily decreasing (e.g., ...). Figure 5 As shown), when it is necessary to connect the second elastic rope 110 to the moving rod 13, move both ends of the connecting buckle 51 to both ends of the fixed tube 5, and then use tools such as pliers to deform the connecting buckle 51. After deformation, both ends of the connecting buckle 51 are inserted into the fixed tube 5 and are difficult to remove, thus completing the connection between the second elastic rope 110 and the moving rod 13. When the second elastic rope 110 breaks due to repeated use over a long period of time, tools can be used to pry the connecting buckle 51 to remove both ends of the connecting buckle 51 from the fixed tube 5 to complete the disassembly of the second elastic rope 110. When the fall arrestor plate 41 is inserted into the through groove 4, the fall arrestor plate 41 will be squeezed by a pair of rubber pads 6 and generate a large friction between the rubber pads 6, making it difficult for the fall arrestor plate 41 to leave the through groove 4 (as shown). Figure 3 , Figure 4 and Figure 5 (As shown).

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
