Description

Technical Field

[0001] This utility model relates to the field of arc extinguishing technology, and in particular to an arc extinguishing structure relay. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the input quantity changes to a specified value. When installing a relay and an arc-extinguishing device, an arc-extinguishing structure relay is needed to avoid poor contact.

[0003] According to the search, application number CN216793591U discloses an arc-extinguishing structure for a high-voltage DC relay. The left and right sides of the arc-extinguishing body of the device are movably connected to the brackets via pins. The inner side of the brackets is fixedly connected to the pressure rod located at the top of the arc-extinguishing body. The top of the arc-extinguishing body is provided with a lifting plate. The left and right sides of the bottom of the lifting plate are fixedly connected to the vertical plates. The relay with the arc-extinguishing structure can be pushed up by pushing the lifting plate. The lifting plate uses the vertical plates to pull the sliding rod to slide inside the bracket. The bracket is compressed and rotates around the pin. When the pressure rod located inside the bracket contacts the top of the arc-extinguishing body, the arc-extinguishing body is compressed and positioned.

[0004] The above solution has the following shortcomings: the device achieves the installation limit of the relay by the rubber sleeve abutting against the upper part of the arc extinguisher body. However, the rubber sleeve rotates and abuts against the upper part of the arc extinguisher body with the pin as the axis. Since the pin lacks a positioning structure, when the relay is impacted, the pin will drive the rubber sleeve to rotate, causing the arc extinguisher body to be thrown, which can easily affect the contact position between the arc extinguisher body and the arc extinguisher body. Utility Model Content

[0005] The purpose of this utility model is to provide an arc-extinguishing structure relay to solve the problem mentioned in the background art, where the arc extinguisher body is thrown, which easily affects the contact position between the arc extinguisher bodies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an arc-extinguishing structure relay, comprising:

[0008] The mounting component includes a mounting base and an arc extinguisher body, wherein the upper end face of the mounting base is fitted with the arc extinguisher body;

[0009] The limiting component includes a cavity, a sliding plate, a threaded rod, a mounting port, a suction cup, a sealing ring, a first limiting groove, a relay body, a knob, a through hole, and anti-slip texture;

[0010] The mounting base has a cavity, and a sliding plate is slidably fitted inside the cavity. A threaded rod is rotatably connected to the upper end face of the sliding plate. The mounting base has multiple mounting ports, and a suction cup is fixedly connected to each mounting port. A sealing ring is fixedly connected to the upper end face of each suction cup. The mounting base has a first limiting groove, and a relay body is fixedly connected to the left side of the mounting base.

[0011] Furthermore, one side of the slide plate slides within the first limiting groove, and the first limiting groove is connected to the cavity.

[0012] Furthermore, a knob is fixedly connected to the top end of the threaded rod, and the top end of the threaded rod is fixedly connected to the center of the lower end face of the knob.

[0013] Furthermore, the surface of the knob is fixedly connected with anti-slip texture, the right side of the mounting base has a through hole that communicates with the cavity, and the surface of the threaded rod is threadedly connected inside the mounting base.

[0014] Furthermore, the limiting component also includes a sleeve, a piston, a rod, a spring, a limiting plate, an arc extinguisher body, and a second limiting groove;

[0015] A sleeve is fixedly connected to the upper end face of the mounting base, a piston is slidably connected to the inner wall of the sleeve, a rod is fixedly connected to the center of the upper end face of the piston, a spring is sleeved on the surface of the rod, a limit plate is fixedly connected to the top end of the rod, and the lower end face of the limit plate abuts against the arc extinguisher body.

[0016] Furthermore, a second limiting groove is provided on the upper end surface of the mounting base, and the bottom end of the arc extinguisher body is sleeved in the second limiting groove.

[0018] Furthermore, the top end of the spring is fixedly connected to the lower end face of the limiting plate, and the bottom end of the spring is fixedly connected to the upper end face of the sleeve.

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] I. This utility model includes a sealing ring, a knob, a cavity, a suction cup, and an arc extinguisher body. When the arc extinguisher body is pressed against the sealing ring, the knob is turned counterclockwise to control the sliding plate to slide downward in the cavity, so that the suction cup is in a vacuum negative pressure state, which holds the bottom of the arc extinguisher body, thereby limiting the arc extinguisher body and making the arc extinguisher body more stable on the mounting base, preventing the arc extinguisher body from being thrown when the mounting base is impacted.

[0021] Second, based on the above-mentioned beneficial effects, a spring and a sleeve are provided. When the spring and sleeve are pulled upward, it is convenient to move the arc extinguisher body into the mounting base and fully abut against the top of the suction cup. When the limiting plate is released, the spring and sleeve drive the limiting plate to move downward and smoothly abut against the top of the arc extinguisher body, further improving the stability of the arc extinguisher body.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-4 As shown, this embodiment is an arc-extinguishing structure relay, including:

[0033] The mounting components include a mounting base 15 and an arc extinguisher body 6, with the arc extinguisher body 6 sleeved on the upper end face of the mounting base 15.

[0034] The limiting component includes a cavity 7, a sliding plate 9, a threaded rod 10, a mounting port, a suction cup 11, a sealing ring 12, a first limiting groove 8, a relay body 1, a knob 14, a through hole 13, and anti-slip texture.

[0035] The mounting base 15 has a cavity 7, and a sliding plate 9 is slidably sleeved in the cavity 7. A threaded rod 10 is rotatably connected to the upper end face of the sliding plate 9. The mounting base 15 has multiple mounting ports, and a suction cup 11 is fixedly connected to each mounting port. A sealing ring 12 is fixedly connected to the upper end face of each suction cup 11. The mounting base 15 has a first limiting groove 8, and a relay body 1 is fixedly connected to the left side of the mounting base 15.

[0036] The cavity 7 allows the slide plate 9 to slide on the inner wall of the mounting base 15, releasing the air inside the mounting base 15 to the outside, so that the suction cup 11 can be in a vacuum negative pressure state, thereby achieving adsorption on the bottom of the arc extinguisher body 6. The sealing ring 12 further improves the sealing effect between the suction cup 11 and the bottom of the arc extinguisher body 6.

[0037] One side of the slide plate 9 slides within the first limiting groove 8, and the first limiting groove 8 is connected to the cavity 7;

[0038] The first limiting groove 8 has a limiting effect on the slide plate 9, making the slide plate 9 more stable when sliding vertically up and down;

[0039] A knob 14 is fixedly connected to the top end of the threaded rod 10, and the top end of the threaded rod 10 is fixedly connected to the center of the lower end face of the knob 14.

[0040] The knob 14 facilitates the control of the rotation of the threaded rod 10, thereby driving the slide plate 9;

[0041] The surface of the knob 14 is fixedly connected with anti-slip texture. The right side of the mounting base 15 has a through hole 13 that communicates with the cavity 7. The surface of the threaded rod 10 is threadedly connected inside the mounting base 15.

[0042] Working principle: When the operator needs to limit the arc extinguisher body 6, the arc extinguisher body 6 is moved above the sealing ring 12, the knob 14 is turned counterclockwise and the threaded rod 10 is driven, so that the slide plate 9 slides vertically downward along the inner wall of the cavity 7 and the first limiting groove 8. The gas under the slide plate 9 is discharged outward through the through hole 13, so that the suction cup 11 is in a vacuum state and firmly adsorbs the bottom of the arc extinguisher body 6 for installation and limiting. It is more stable when connected to the relay body 1.

[0043] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment 1, and the limiting component also includes a sleeve 2, a piston, a sleeve rod 3, a spring 4, a limiting plate 5, an arc extinguisher body 6, and a second limiting groove 16;

[0044] A sleeve 2 is fixedly connected to the upper end face of the mounting base 15. A piston is slidably connected to the inner wall of the sleeve 2. A sleeve rod 3 is fixedly connected to the center of the upper end face of the piston. A spring 4 is sleeved on the surface of the sleeve rod 3. A limit plate 5 is fixedly connected to the top of the sleeve rod 3. The lower end face of the limit plate 5 abuts against the arc extinguisher body 6.

[0045] The limit plate 5 can be easily pulled upward by the sleeve rod 3 and the spring 4, so that the arc extinguisher body 6 can be inserted into the mounting base 15 more smoothly. When the limit plate 5 is not pulled, the lower part of the limit plate 5 abuts against the upper part of the arc extinguisher body 6, further improving the limiting effect.

[0046] The upper end face of the mounting base 15 is provided with a second limiting groove 16, and the bottom end of the arc extinguisher body 6 is sleeved in the second limiting groove 16.

[0047] The second limiting groove 16 makes the arc extinguisher body 6 more stable when it is inserted into the mounting base 15;

[0048] The lower end face of the arc extinguisher body 6 overlaps with the upper end face of the sealing ring 12;

[0049] The top end of the spring 4 is fixedly connected to the lower end face of the limiting plate 5, and the bottom end of the spring 4 is fixedly connected to the upper end face of the sleeve 2.

[0050] Working principle: When the arc extinguisher body 6 moves into the mounting base 15, the spring 4 and the sleeve rod 3 pull the limiting plate 5 upward, so that the bottom of the limiting plate 5 is higher than the horizontal line above the mounting base 15, allowing the arc extinguisher body 6 to be inserted into the mounting base 15 to avoid obstruction. When the arc extinguisher body 6 enters the mounting base 15, the pulling of the limiting plate 5 stops, so that the bottom of the limiting plate 5 is inserted into the top of the arc extinguisher body 6 for limiting. By limiting the upper and lower parts of the arc extinguisher body 6, the arc extinguisher body 6 is more stable in the mounting base 15, avoiding poor contact between the relay body 1 and the arc extinguisher body 6.
