Technical Field

[0001] This utility model belongs to the field of meter technology, specifically relating to a meter button. Background Technology

[0002] In the electricity meter industry and other smart metering products, some buttons have functions such as parameter editing and mode switching, but these functions are only authorized to the product maintenance and metering units. To ensure that the product is not maliciously modified and causes information and metering errors, lead seals are used to protect the button usage rights.

[0003] The utility model application with application number 2023202959421 discloses a rotating lead seal button, including a watch cover that is detachably connected and fixed to the watch case. A circuit board is provided on the inner side of the watch case. A lead seal button for matching the circuit board is inserted into the watch cover. One end of the lead seal button is located inside the outer wall of the watch cover, and the other end is connected to a conductive silicone button for connecting and matching the circuit board. A mating hole is provided at the end of the lead seal button away from the circuit board. A wire hole is provided on the watch cover for mating with the mating hole and connecting the lead seal. The disadvantages of the above-mentioned rotating lead seal button are: (1) it is difficult to align the mating hole and the wire hole on the rotating lead seal button, which is not conducive to the installation of the lead seal wire and affects the assembly efficiency; (2) the mating hole is located in the groove for rotating the rotating lead seal button. When rotating the rotating lead seal button, the lead seal wire cannot be passed through, and when passing through the lead seal wire, the rotating lead seal button cannot be rotated, which further increases the difficulty of installing the lead seal wire. Summary of the Invention

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] A meter button is rotatably mounted on a meter 2. One end of the lead-sealed button 1 extends to the outside of the meter 2, allowing the user to control the lead-sealed button 1 from the outside of the meter 2. The other end extends into the meter 2, connecting the lead-sealed button 1 to the circuit board inside the meter 2, enabling parameter adjustment or operating mode switching. After the lead-sealed button and meter 2 are assembled, an external lead-sealed wire connects the lead-sealed button 1 and meter 2, fixing them relatively in place. This prevents the lead-sealed button 1 from operating the circuit board during meter 2 use and also facilitates observation of any potential risk of the lead-sealed button 1 being activated during meter 2 use.

[0028] The lead-sealed key 1 includes a pivot 1-3 and a keycap 1-10 connected to the top of the pivot 1-3. The keycap 1-10 has a mating hole 1-1 and a lead-sealing groove 1-8. The axis of the mating hole 1-1 is along the diameter of the keycap 1-10. The lead-sealing groove 1-8 communicates with the mating hole 1-1, allowing the lead-sealing wire to pass through the mating hole 1-1 and then extend out of the keycap 1-10 through the lead-sealing groove 1-8. To facilitate the lead-sealing wire's exit from the keycap 1-10, the depth of the lead-sealing groove 1-8 gradually decreases from the mating hole 1-1 side towards the edge of the keycap 1-10. To facilitate observation of the position of the mating hole 1-1, a mark 1-11 is provided on the top of the keycap 1-10, directly above the mating hole 1-1. To facilitate the rotation of the lead seal button 1, finger grooves 1-7 are provided on both sides of the lead seal groove 1-8. The operator's two paper collection tools are respectively placed into the finger grooves 1-7, and the lead seal button 1 is rotated by the fingers, so as to improve the rotation convenience of the lead seal button 1.

[0029] To prevent the mating hole 1-1 from affecting the strength of the lead-sealed key 1, the pivot 1-3 and the keycap 1-10 are connected by a connecting block 1-9. Preferably, the orientation of the connecting block 1-9 is consistent with the axial direction of the mating hole 1-1.

[0030] A mating step 1-4 is provided on the lower end face of the keycap 1-10, and the mating step 1-4 is arranged along the circumferential sidewall edge of the keycap 1-10. A guide surface 1-5 and a limiting surface 1-6 are respectively provided on both sides of the mating step 1-4. The guide surface 1-5 is used to guide the lifting and lowering of the keycap 1-10, and the limiting surface 1-6 is used to restrict the rotation of the keycap 1-10 when the lead-sealed key 1 is installed. A limiting plate 1-2 is provided between the pivot 1-3 and the mating step 1-4, and the limiting plate 1-2 is connected to both the pivot 1-3 and the mating step 1-4. The limiting plate 1-2 is used to align the mating hole 1-1 and the wire hole 2-1.

[0031] Meter 2 includes a cover 2-7 and a base 2-8 that are assembled together. The cover 2-7 has a button hole 2-3 for mounting the lead-sealed button 1. The button hole 2-3 includes a first stepped section 2-9 and a second stepped section 2-10. A rotating shaft 1-3 is rotatably connected to the first stepped section 2-9 and extends into the meter 2 through the first stepped section 2-9. The button cap 1-10 is rotatably mounted within the second stepped section 2-10. A guide step 2-4 is provided within the second stepped section, and the guide step 2-4 is adapted to the mating step 1-4; that is, the guide step 2-4 and the mating step 1-4 are located on the same circumference. The guide step 2-4 is provided with a guide ramp 2-11. The guide surface 1-5 is adapted to the guide ramp 2-11. That is, when the guide surface 1-5 and the guide ramp 2-11 abut against each other, the lead seal button 1 is lifted up under the guiding action of the guide ramp 2-11. The top surface of the guide step 2-4 is provided with a rotation limiting step 2-6. The rotation limiting step 2-6 and the guide ramp 2-11 are located on both sides of the guide step 2-4. The limiting surface 1-6 is adapted to the rotation limiting step 2-6. That is, when the lead seal button 1 is installed, the limiting surface 1-6 and the rotation limiting step 2-6 abut against each other. A positioning plate 2-2 is provided between the inner side wall of the guide step 2-4 and the circumferential side wall of the first step section 2-9. The positioning plate 2-2 is adapted to the limiting plate 1-2. That is, when the positioning plate 2-2 and the limiting plate 1-2 abut, the mating hole 1-1 is set opposite to the wire hole 2-1.

[0032] The top of the positioning plate 2-2 and the top surface of the guide step 2-4 are on the same plane. The lower end face of the limiting plate 1-2 extends to below the top surface of the guide step 2-4 so that the limiting plate 1-2 and the positioning plate 2-2 can be positioned together, thereby facilitating the alignment of the mating hole 1-1 with the wire hole 2-1.

[0033] During the installation of the lead seal button 1, in order to prevent the lead seal button 1 from rotating relative to the meter 2 and causing inconvenience to the installation of the lead seal button 1, a relief groove 2-5 is provided on the end face of the second step section 2-10. The relief groove 2-5 is adapted to the limiting plate 1-2. That is, since the lower end face of the limiting plate 1-2 extends to the bottom of the top surface of the guide step 2-4, when the lead seal button 1 and the rotating limiting step 2-6 abut, the limiting plate 1-2 is inserted into the relief groove 2-5.

[0034] The installation steps for the lead seal button 1 are as follows:

[0035] (1) The lead seal button 1 is rotatably installed in the button hole 2-3 via the rotating shaft 1-3.

[0036] (2) Rotate the lead seal button 1 so that the limiting surface 1-6 and the rotating limiting step 2-6 abut against each other. At this time, the limiting plate 1-2 is set directly opposite the relief groove 2-5. Press the lead seal button 1 so that the limiting plate 1-2 is inserted into the relief groove 2-5. At this time, the bottom of the rotating shaft 1-3 is fully extended from the lower end face of the cover 2-7, so that the sealing ring 3 and the conductive silicone button 4 can be installed at the bottom of the rotating shaft 1-3.

[0037] (3) Insert the screwdriver into the lead seal groove 1-8 and rotate the lead seal button 1 by the screwdriver. Under the guidance of the guide slope 2-11, the lead seal button 1 is lifted up. Continue to rotate the lead seal button 1 so that the limit plate 1-2 and the positioning plate 2-2 abut. At this time, the mating hole 1-1 is directly opposite the wire hole 2-1, which makes it easy to pass the lead seal wire through the wire hole 2-1.
