Description

TECHNICAL FIELD

[0001] The utility model relates to relay field, specifically point to a kind of relay with regulating function. BACKGROUND

[0002] Relay is a kind of circuit control element, often installed in distribution box, for playing the role of automatic regulation, safety protection and conversion circuit in circuit.

[0003] The way that relay is connected in main circuit is similar to the way that plug is inserted into socket in daily life. Relay also has corresponding plug rod, which is inserted into the slot of base. In order to make contact with relay, metal spring sheet is installed in the slot of base. The top end of spring sheet is close to the center of slot under the action of its own elastic force. After plug rod enters the slot, it is pressed and makes contact with plug rod. As a long-term pressure-bearing part, spring sheet will be fatigued. Its elasticity will decrease after long-term work, so that it cannot make effective contact with plug rod. Therefore, the connection between relay and main circuit becomes unstable, and even disconnected. SUMMARY

[0009] Further, the dial comprises a support plate, a plurality of guide columns are connected between the edges of the support plate, and a plurality of guide rods for dialing the guide columns are connected to one side edge of the rotating disc.

[0010] Further, the support shaft extends to the outside of the cover and is connected with a handle, and a six-sided slot is connected to the handle.

DETAILED DESCRIPTION

[0021] The utility model will be further described in detail in combination with the drawings.

[0022] Example one

[0023] Combined with appendix Figures 1-6 To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a relay with an adjustment function, including a housing 1, a plurality of insert rods 13 connected to the top of one side of the housing 1, a locking block 15 connected to the bottom of one side of the housing 1, a mounting plate 2 connected inside the housing 1, a support column 3 rotatably connected between the housing 1 and the mounting plate 2, a bushing 12 connected to the support column 3, the insert rods 13 being connected to the bushing 12, a dial wheel 4 connected to the support column 3, the dial wheel 4 including a support plate 5, the edges of the support plate 5 being connected together. The cover 1 is provided with multiple guide posts 6. Multiple support shafts 7 are rotatably connected to the top of the cover 1 away from the insertion rod 13. One end of the support shaft 7 extends to the outside of the cover 1 and is connected to a handle 8. A hexagonal groove 9 is connected to the handle 8. The support shaft 7 and the cover 1 are rotatably connected to each other by a certain resistance. One end of the support shaft 7 extends into the cover 1 and is connected to a turntable 10 for driving the dial 4 to rotate. Multiple guide rods 11 for turning the guide posts 6 are connected to one edge of the turntable 10. Multiple clearance holes 14 that cooperate with the insertion rod 13 are connected to the top of the cover 1.

[0024] The housing 1 provides a enclosure for the relay, and the various components that make up the relay are installed and stored inside the housing. The locking block 15 at the bottom of the housing is used to fix the relay to the corresponding base position in the distribution box by snapping it in place. The plug rod 13 is a conductive part in which the relay is integrated into the circuit system of the distribution box. By holding the handle 8 and rotating the support shaft 7, the guide rod 11 on the turntable 10 pushes and pulls the guide post 6, causing the dial wheel 4 and the support post 3 to rotate. The connection of the support shaft 7 to the housing 1 is such that it rotates under a certain resistance. This resistance is relatively stable and will not rotate if the support shaft 7 is not guided by excessive external force. Therefore, it can maintain the stability of the support column 3. The part that drives the support shaft 7 to rotate is a handle 8 that is easy to hold. One side of the handle 8 is provided with a hexagonal groove 9. So even if the relay is deep in the distribution box components and it is inconvenient for personnel to put their hands into the distribution box to operate, a longer hexagonal groove can be inserted into the hexagonal groove 9 of the handle 8 to control the rotation of the support shaft 7. When the support shaft 7 rotates and the dial 10 of the dial 4 is driven, the support column 3 carries the plug rod 13 to rotate to one side, so that the plug rod 13 can effectively contact the conductive spring plate inside the base slot, and achieve a good power supply effect after adjustment.

[0025] In practical implementation of this invention, when the spring sheet in the base slot becomes loose during relay installation or operation, the support shaft 7 can be rotated by holding the handle 8. The support shaft 7 carries the guide rods 11 on the turntable 10 and rotates around the support shaft 7. The ends of the guide rods 11 extend into the inside of the dial wheel 4, and their ends push the guide post 6 to move, thereby making the dial wheel 4 rotate. Then, the support post 3, which is the main support structure of the dial wheel 4, will rotate to a corresponding degree, driving the plug rod 13 installed on it to rotate to one side and move the end of the plug rod 13 towards the slot. After the plug rod 13 moves, it is more tightly attached to the conductive spring sheet in the slot, eliminating the poor contact between the relay body and the base caused by the loose spring sheet or decreased elasticity. By adjusting the position of the plug rod 13, the relay and the corresponding control circuit can obtain normal power-on operation.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
