Description

Technical Field

[0001] This utility model relates to the technical field of button assembly devices, specifically to an electrical instrument button assembly device. Background Technology

[0002] In today's power industry, power meters play a crucial role. With continuous technological advancements, the requirements for the accuracy of power parameter measurement, the monitoring and analysis capabilities of power quality, and the control of electrical equipment are becoming increasingly stringent. As key operational components, the buttons on power meters directly impact the user experience and operational efficiency of the entire system. Buttons of different shapes and sizes meet various operational needs, with the larger, round power start button being particularly important because it is easier to identify and press, ensuring rapid startup of the power meter.

[0003] A button comprises multiple components, including a button cap, return spring, moving contact, stationary contact, housing, push-button switch, button gasket, and button pins, all requiring precise manufacturing processes. The quality of each component directly affects the overall performance of the button. For example, the spring constant of the return spring determines the button's feel and return speed; the material and contact performance of the moving and stationary contacts affect the button's electrical conductivity reliability. While separate production of parts improves efficiency and specialization, it also presents assembly challenges. Accurately assembling these parts requires strict process flows and high-precision equipment. Especially after the internal electrical components are installed, the installation of the button cap becomes a critical step. Existing button cap installation methods require first using a clamp to pick up the button cap and move it onto the base, then pressing it down and securing it with a pressing assembly.

[0004] However, in the existing button cap installation method, the movement and clamping of the button cap are carried out separately. If the button cap is subjected to external force interference or the clamp is not accurate enough during the clamping and movement process, the position of the button cap and the base may be inaccurate, resulting in instability when pressing and tightening, and thus causing the button cap installation to fail. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical instrument button assembly device to solve the problem that the existing button cap installation method, in which the movement and clamping of the button cap are carried out separately, is prone to inaccurate positioning of the button cap and the base, resulting in button cap installation failure.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: an electrical instrument button assembly device, comprising a housing, a limiting block, and two clamping blocks. The housing contains a lifting component for raising and lowering the limiting block. The bottom of the housing has an opening, on which the limiting block and the two clamping blocks are located. The limiting block has a limiting plate, and through slots are formed on both sides of the limiting block. Each of the two clamping blocks has a rotating shaft, and each rotating shaft is slidably connected to the through slot. The limiting block and the two clamping blocks are slidably connected to the housing. Each clamping block has a sliding groove. Two rotating rods are rotatably connected within the housing. Each of the two rotating rods has an L-shaped clamping push rod, the long side of which is slidably connected to the sliding groove. The short side of the L-shaped clamping push rod is located directly above the limiting plate. The housing contains a reset unit for resetting the L-shaped clamping push rod.

[0007] The working principle of this utility model is as follows: When assembling the button, first move the device directly above the button cap, then lower the housing so that the limiting block abuts against the button cap. Continue lowering the housing, and the button cap moves upward against the limiting block until the bottom of the through groove contacts the rotating shaft. Then, the lifting component drives the limiting block and the limiting plate to rise. During the upward movement of the limiting plate, the short sides of the two L-shaped clamping push rods move upward, thereby causing the two rotating rods to rotate. At this time, the long sides of the two L-shaped clamping push rods slide into the housing, thereby pushing the two clamping blocks downward and inward to retract. The button cap is clamped, and then the device is moved directly above the assembly base. Next, the lifting component pushes the limiting block and the limiting plate downwards. At the same time, the limiting plate releases the push on the short sides of the two L-shaped clamping push rods, causing the short sides of the L-shaped clamping push rods to move downwards under the action of the reset unit. This causes the two rotating rods to rotate, and at this time, the long sides of the two L-shaped clamping push rods slide out of the housing, thereby pushing the two clamping blocks upwards and causing the clamping blocks to open, so that the clamping blocks release the clamping of the button cap. Then, the lifting component continues to push the limiting block downwards, and the button cap is fastened to the base.

[0008] The beneficial effects of this utility model are as follows: by cooperating with the electric telescopic rod, the limiting block and the clamping block, the situation where the button cap may shift due to separate installation steps can be avoided. The clamping and moving of the button cap can be carried out simultaneously, which improves the accuracy and efficiency of installation. In addition, the structure is simple, the operation is convenient, and the production cost and operation difficulty are reduced.

[0009] Option 2, a preferred embodiment of the basic option, includes a reset rod, a support plate inside the housing, a through hole on the support plate, a reset rod slidably connected to the through hole, a first spring sleeved on the reset rod, one end of the first spring being fixedly connected to the bottom of the support plate, and the reset rod being located directly above the short side of the L-shaped clamping push rod. By setting the reset rod and the first spring, the L-shaped clamping push rod can be quickly reset.

[0010] Option 3, a preferred embodiment of the basic option, involves an electric telescopic rod as the lifting component. The electric telescopic rod is fixedly connected to the housing. A limiting hole is provided on the limiting plate, and the telescopic end of the electric telescopic rod is slidably connected to the limiting hole. A stop block is detachably connected to the telescopic end of the electric telescopic rod, and the diameter of the stop block is larger than the diameter of the limiting hole. The use of the electric telescopic rod makes the lifting of the limiting block more stable and precise, while the stop block ensures that the limiting block will not detach from the electric telescopic rod.

[0011] Option 4, which is a preferred option of Option 3, is provided with a second spring on the stop block, and the second spring is connected to the limit block; by setting the second spring, a buffering effect can be achieved, reducing the impact on the components during the lifting process.

[0012] Option 5, which is a preferred option of the basic option, has handles on both sides of the housing; by setting handles, it is convenient for operators to move the device.

[0013] Option 6, which is a preferred option of the basic option, has a door hinged to one side of the housing; by setting the door, maintenance and repair are facilitated. Attached Figure Description

The clamping blocks 6 have sliding grooves 13. Two rotating rods 7 are rotatably connected inside the housing 1. The two rotating rods 7 are fixedly connected to the L-shaped clamping push rods 8. The long side of the L-shaped clamping push rods 8 is slidably connected to the sliding grooves 13. The short side of the L-shaped clamping push rods 8 is located directly above the limiting plate 4.

[0021] The housing 1 is provided with a reset unit for resetting the L-shaped clamping push rod 8. The reset unit includes a reset rod 9. A support plate 14 is fixedly connected inside the housing 1. The support plate 14 has a through hole. The reset rod 9 is slidably connected to the through hole. A first spring 10 is sleeved on the reset rod 9.

Then, the handle 15 moves the device to the top of the assembly base, and the electric telescopic rod 2 is activated. The telescopic end of the electric telescopic rod 2 pushes the limiting block 3 and the limiting plate 4 downward. At the same time, the limiting plate 4 releases the push on the short side of the two L-shaped clamping push rods 8, so that the short side of the L-shaped clamping push rods 8 moves downward under the push of the reset rods 9 and the first springs 10, thereby causing the two rotating rods 7 to rotate. At this time, the long side of the two L-shaped clamping push rods 8 slides out of the housing 1, thereby pushing the two clamping blocks 6 to move upward and causing the clamping blocks 6 to open, so that the clamping blocks 6 release the clamp on the button cap. Then the electric telescopic rod 2 continues to push the limiting block 3 downward, and the button cap is fastened to the base.
