[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 A start-stop control device for a gas generator set includes a main cabinet 1, which comprises multiple control boxes 2. Each control box 2 has a door 3 on its front, and a start-stop control knob 4 is mounted on the door 3. The door 3 is pivotally connected to the control box 2 via a hinge mechanism 6. In addition to the start-stop control knob 4, the door 3 also has a central control panel. The start-stop control knob 4 includes a forced trip button, a start-allow button, a DC power switch button, a voltage setting button, and an emergency stop button, etc., which will not be described in detail here.

[0023] The hinge mechanism 6 includes a first hinge plate 7 and a second hinge plate 8. The first hinge plate 7 is detachably connected to the outside of the door 3, and the second hinge plate 8 is detachably connected to the outside of the control box 2.

[0024] The second hinge plate 8 has a movable groove 11 on the side facing the first hinge plate 7. A cylindrical pin 12 is provided in the movable groove 11. The cylindrical pin 12 is fixedly connected to the second hinge plate 8. The end of the first hinge plate 7 near the second hinge plate 8 is fitted over the outside of the cylindrical pin 12. The first hinge plate 7 and the cylindrical pin 12 are rotatably connected. The upper and lower ends of the first hinge plate 7 are fixedly connected with a ring structure for adjusting the damping of the first hinge plate 7 and the cylindrical pin 12.

[0025] The ring structure fixed at the upper and lower ends of the first hinge plate 7 can rotate together with the first hinge plate 7. When the first hinge plate 7 and the second hinge plate 8 become loose, the ring structure increases the damping between the first hinge plate 7 and the cylindrical pin 12 from the top and bottom of the first hinge plate 7, which can keep the first hinge plate 7 stable when rotating, improve the opening and closing stability of the door 3, and increase the service life of the door 3.

[0026] To facilitate the disassembly and replacement of the hinge mechanism 6, in a preferred embodiment, pressure plates 9 are provided on the inner sides of both the control box 2 and the door 3. Multiple first fastening bolts 10 are mounted on the pressure plates 9. Bolt holes that mate with the first fastening bolts 10 are provided on the control box 2 and the door 3. The first fastening bolts 10 pass through the bolt holes and are threadedly connected to the threaded holes provided on the inner sides of the first hinge plate 7 and the second hinge plate 8.

[0027] During installation, the corresponding pressure plate 9 is placed inside the control box 2 and the door 3. The first fastening bolt 10 is rotated, passing through the pressure plate 9 and screwed into the bolt holes on the control box 2 and the door 3. Then, the first hinge plate 7 and the second hinge plate 8 are fitted onto the edges of the door 3 and the control box 2. The first fastening bolt 10 is then screwed into the threaded holes on the inner sides of the first hinge plate 7 and the second hinge plate 8, thus completing the fixing of the hinge mechanism 6. The disassembly and assembly of the hinge mechanism 6 are similar and will not be explained further here.

[0028] Regarding the ring structure:

[0029] The ring structure includes a sleeve 13, which is fitted around the cylindrical pin 12 and is rotatably connected to the cylindrical pin 12. A fixing pin 15 is provided on the side of the sleeve 13 near the second hinge plate 8, and the fixing pin 15 is fixedly connected to the first hinge plate 7. Two clamps 16 are provided on the other side of the sleeve 13, and a fastening mechanism is provided on the clamps 16 for tightening the sleeve 13.

[0030] The end of the clamp 13 furthest from the clamp nozzle 16 is fixed to the first hinge plate 7 by a fixing pin 15. When the first hinge plate 7 rotates around the cylindrical pin 12, the clamp 13 also rotates accordingly. At this time, the clamp 13 does not affect the rotation of the first hinge plate 7. When the hinge mechanism 6 becomes loose due to prolonged use, the clamp 13 can be tightened by the fastening mechanism on the clamp nozzle 16. The circle around the clamp 13 becomes smaller and squeezes the cylindrical pin 12, increasing the damping between the cylindrical pin 12 and the clamp 13, ensuring the stable opening and closing of the hinge mechanism 6.

[0031] Specifically, the fastening mechanism includes a second fastening bolt 17, which passes through two clamps 16. The clamps 16 have movable holes that mate with the second fastening bolt 17. One end of the second fastening bolt 17 is provided with a nut, and the other end of the second fastening bolt 17 is provided with a nut 18, which is threadedly connected to the second fastening bolt 17.

[0032] The second fastening bolt 17 is assembled on the two clamps 16. Using a tool, tighten the nut 18. The nut 18 will work with the nut to squeeze the two clamps 16. The sleeve 13 will produce elastic deformation, squeezing the cylindrical pin 12 and adjusting the damping between the cylindrical pin 12 and the sleeve 13.

[0033] To protect the sleeve 13 and the cylindrical pin 12, in a preferred embodiment, a damping ring 14 is provided on the inner side of the sleeve 13, and the damping ring 14 is fixedly connected to the sleeve 13. When the sleeve 13 is tightened, the damping ring 14 will replace the sleeve 13 in contact with the cylindrical pin 12, so as to reduce the frictional damage to the cylindrical pin 12 when the sleeve 13 rotates.

[0034] In the preferred embodiment, both the nut and the bolt 18 have washers on the side facing the clamp 16, and the washers are fitted over the outside of the bolt 18. The washers fitted over the outside of the bolt 18 act as buffers, providing protection for the nut and bolt 18 when the bolt 18 is tightened, and distributing the pressure on the nut and bolt 18.

[0035] It is worth explaining in detail that a handle 5 is provided on the outside of the door 3. The handle 5 is fixedly connected to the door 3, and a rubber layer is provided on the outside of the handle 5. In addition to its anti-slip function, the rubber layer also provides insulation.

[0036] Working principle:

[0037] The start / stop control knob 4 includes a forced trip button, a start enable button, a DC power switch button, a voltage setting button, and an emergency stop button. The start / stop operation of the gas generator set is controlled via the start / stop control knob 4 on the main cabinet 1. The ring structure fixed to the upper and lower ends of the first hinge plate 7 rotates with the first hinge plate 7. When loosening occurs between the first hinge plate 7 and the second hinge plate 8, the ring structure increases the damping between the first hinge plate 7 and the cylindrical pin 12 from the top and bottom, ensuring smooth rotation of the first hinge plate 7, improving the opening and closing stability of the cabinet door 3, and extending the service life of the cabinet door 3.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
