Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a keyboard pull-down clamping assembly. Background Technology

[0002] A computer keyboard is a common computer peripheral. It is usually connected to the computer host via a USB interface or serial port and is used to input operation commands.

[0003] Computer keyboards require clamping during processing. However, existing clamping tools generally use motor drives, as can be seen in Chinese patent CN219837684U, which uses pneumatic motors on both sides. While automatic methods are convenient, the keyboards need to be sprayed and baked. If the motors are exposed to high temperatures, they are prone to damage, resulting in higher processing costs. If the keyboards are disassembled and placed on a carrier for processing, it would increase the number of steps, reduce work efficiency, and fail to meet current production needs.

[0004] To solve the above problems, it is necessary to provide a keyboard pull-down clamping component. Utility Model Content

[0005] The purpose of this invention is to provide a keyboard pull-down clamping component that is free of electric equipment, easy to move, applicable to multiple production scenarios, and manually operated.

[0006] To achieve the above objectives, the keyboard pull-down clamping assembly provided by this utility model includes a worktable and a clamp. The worktable has a clamp on each of its two sides. Each clamp includes a fixed base, a rotating plate, and a clamping member. The fixed base is mounted on the worktable. One side of the rotating plate is pivotally connected to the fixed base, and the other side of the rotating plate is pivotally connected to the lower end of the clamping member. The upper end of the clamping member has a clamping hook. A circular arc through hole is formed in the middle of the clamping member. The fixed base has a movable column corresponding to the circular arc through hole. The movable column is movably disposed within the circular arc through hole. The clamping member moves up and down under the drive of the rotating plate, allowing the movable column to move within the circular arc through hole. The circular arc through hole has a first frosted surface, and the movable column has a second frosted surface corresponding to the first frosted surface. The contact between the first and second frosted surfaces increases the friction between the circular arc through hole and the movable column.

[0007] Preferably, the keyboard pull-down clamping assembly further includes an operating handle, which includes an extension rod and a grip ball. One end of the extension rod is connected to the rotating plate, and the other end of the extension rod is connected to the grip ball. The rotating plate is rotated by turning the extension rod.

[0008] Preferably, the extension rod is bent.

[0009] Preferably, the extension rod is detachably connected to the rotating plate.

[0010] Preferably, one of the rotating plates corresponds to two of the clamping members, and the clamping members are symmetrically arranged on both sides of the rotating plate.

[0011] Preferably, the pressing surface of the clamping hook has an elastic pressing layer, which is a rubber layer.

[0012] Preferably, the fixing seat has a receiving groove corresponding to the clamping member, the clamping member is inserted into the receiving groove, and the movable column is installed in the receiving groove and cooperates with the arc-shaped through hole of the clamping member.

[0013] Preferably, the fixture has a mounting portion, the worktable extends corresponding to the mounting portion to form a mounting ear, and the mounting portion is threadedly connected to the mounting ear.

[0014] Preferably, the cross-section of the arc-shaped through hole has an arc-shaped structure.

[0015] Preferably, the worktable is a metal worktable and the fixture is a metal fixture.

[0016] Compared with the prior art, the keyboard pull-down clamping assembly provided by this utility model combines a workbench and a clamp. A clamp is provided on both sides of the workbench, and the clamp includes a fixed base, a rotating plate, and a clamping member. The fixed base is mounted on the workbench, one side of the rotating plate is pivotally connected to the fixed base, and the other side of the rotating plate is pivotally connected to the lower end of the clamping member. The upper end of the clamping member has a clamping hook, and the middle of the clamping member has an arc-shaped through hole. The fixed base has a movable column corresponding to the arc-shaped through hole, which is movably disposed within the arc-shaped through hole. The clamping member moves up and down under the drive of the rotating plate, allowing the movable column to move within the arc-shaped through hole. The arc-shaped through hole has a first frosted surface, and the movable column has a second frosted surface corresponding to the first frosted surface. The contact between the first and second frosted surfaces increases the friction between the arc-shaped through hole and the movable column. Due to the friction between them, a certain amount of force is required to pry the rotating plate, thereby clamping or releasing the clamping member, thus achieving a locking purpose. Since no electric equipment is installed, the workbench and fixtures can all be made of metal. Therefore, the keyboard can be switched freely in multiple processing scenarios, making it easy to move without having to transfer it to other carriers for baking or other processes.

[0023] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0024] Please see Figures 1 to 6 This illustration shows the specific structure of the keyboard pull-down clamping assembly 100 of this utility model. The keyboard pull-down clamping assembly 100 includes a worktable 1 and a clamp 2. A clamp 2 is provided on both sides of the worktable 1, and a raised seat is provided at the bottom of the worktable 1. The clamp 2 includes a fixed seat 21, a rotating plate 22, and a clamping member 23. The fixed seat 21 is installed on the worktable 1. One side of the rotating plate 22 is pivotally connected to the fixed seat 21, and the other side of the rotating plate 22 is pivotally connected to the lower end of the clamping member 23. The upper end of the clamping member 23 has a clamping hook 231, and the middle part of the clamping member 23 has an arc-shaped through hole 232. The fixed seat 21 has a movable post 211 corresponding to the arc-shaped through hole 232. 11 is movably disposed in the arc-shaped through hole 232. The clamping member 23 moves up and down under the drive of the rotating plate 22, so that the movable column 211 moves within the arc-shaped through hole 232. The arc-shaped through hole 232 has a first frosted surface 2321, and the movable column 211 has a second frosted surface 2111 corresponding to the first frosted surface 2321. The contact between the first frosted surface 2321 and the second frosted surface 2111 increases the friction between the arc-shaped through hole 232 and the movable column 211. Due to the friction between the two, a certain amount of force is required to pry the rotating plate 22, thereby actuating the clamping member 23 to clamp or loosen, thus achieving a locking purpose. Since no electric equipment is set, both the workbench 1 and the clamp 2 can be uniformly made of metal. Therefore, the keyboard can be switched arbitrarily in multiple processing scenarios, which is convenient for transfer without having to transfer it to other carriers for baking and other processes. More specifically, as follows:

[0025] Please see Figure 6 The keyboard pull-down clamping assembly 100 also includes an operating handle 24, which includes an extension rod 241 and a gripping ball 242. One end of the extension rod 241 is connected to a rotating plate 22, and the other end is connected to the gripping ball 242. By bending the extension rod 241, the rotating plate 22 is rotated. Specifically, the extension rod 241 is bent to extend it, and the manufacturer can adjust it according to the actual situation of the external equipment. Preferably, the extension rod 241 and the rotating plate 22 are detachably connected, but this is not the only possibility. The manufacturer can disassemble and assemble it according to the actual scenario, making it highly adaptable.

[0026] Please see Figures 1 to 6 A rotating plate 22 corresponds to two clamping members 23. The clamping members 23 are symmetrically arranged on both sides of the rotating plate 22, thereby achieving a better clamping effect and higher stability.

[0027] Please see Figure 1 The pressing surface of the pressing hook 231 has an elastic pressing layer 2311. Preferably, the elastic pressing layer 2311 is a rubber layer, but it is not limited to this.

[0028] Please see Figures 1 to 6 The fixed base 21 has a receiving groove 212 corresponding to the clamping member 23. The clamping member 23 is inserted into the receiving groove 212. The movable column 211 is installed in the receiving groove 212 and cooperates with the arc-shaped through hole 232 of the clamping member 23.

[0029] Please see Figures 1 to 6 The fixture 2 has a mounting portion 25, and the worktable 1 extends to form a mounting ear 11 corresponding to the mounting portion 25. The mounting portion 25 is threadedly connected to the mounting ear 11. Preferably, the cross-section of the arc-shaped through hole 232 is an arc-shaped structure.

[0030] Please see Figures 1 to 6 The workbench 1 is a metal workbench 1, and the clamp 2 is a metal clamp 2, so that the keyboard pull-down clamping component 100 of this utility model can enter the oven and other scenarios and achieve arbitrary switching.

[0031] In summary, please refer to Figures 1 to 6 The following is a detailed description of the usage process of the keyboard pull-down clamping assembly 100 of this utility model:

[0032] See initial state Figure 5 As shown, turn the operating handle 24 (turning direction as shown) Figure 5(In the direction indicated by the middle arrow A) Due to the friction between the first frosted surface 2321 and the second frosted surface 2111, a relatively large force is required to turn the operating handle 24. Driven by the operating handle 24, the rotating plate 22 rotates around the pivot point with the fixed base 21. Driven by the rotating plate 22, the clamping member 23 moves downward, so that the movable column 211 moves within the arc-shaped through hole 232, and drives the clamping hook 231 of the clamping member 23 to clamp the workpiece 20. The state after the movement is shown in the figure. Figure 6 To release the lock, simply pry the operating handle 24 to release the clamp 2 from its original position. Figure 6 Status activity to Figure 5 state.

[0033] By combining the workbench 1 and the clamp 2, a clamp 2 is provided on both sides of the workbench 1. The clamp 2 includes a fixed base 21, a rotating plate 22, and a clamping member 23. The fixed base 21 is installed on the workbench 1. One side of the rotating plate 22 is pivotally connected to the fixed base 21, and the other side of the rotating plate 22 is pivotally connected to the lower end of the clamping member 23. The upper end of the clamping member 23 has a clamping hook 231, and the middle of the clamping member 23 has an arc-shaped through hole 232. The fixed base 21 is provided with a movable column 211 corresponding to the arc-shaped through hole 232. The movable column 211 is movably provided in the arc-shaped through hole 232. The clamping member 23 is located on the rotating plate. Driven by 22, the rotating plate moves up and down, causing the movable column 211 to move within the arc-shaped through hole 232. The arc-shaped through hole 232 has a first frosted surface 2321, and the movable column 211 has a second frosted surface 2111 corresponding to the first frosted surface 2321. The contact between the first frosted surface 2321 and the second frosted surface 2111 increases the friction between the arc-shaped through hole 232 and the movable column 211. Due to the friction between them, a certain amount of force is required to turn the rotating plate 22, thereby actuating the clamping member 23 to clamp or release, thus achieving a locking purpose. Since no electric equipment is provided, both the worktable 1 and the clamp 2 can be uniformly made of metal. Therefore, the keyboard can be switched arbitrarily in multiple processing scenarios, facilitating transfer without having to transfer it to other carriers for baking or other processes.

[0034] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
