Technical Field

[0001] The present invention relates to an inner door setting structure for an electric control box, that is, in an electric control box having a double door structure of an outer door and an inner door, the structure for setting the inner door is simplified and the inner door is prevented from opening more than a specified angle. Background Art

[0002] Typically, in various industrial sites, an electric control box is manufactured in various shapes such as a rectangular or square hexahedron or according to set standards so that electrical accessories or an electric control panel connected thereto can be arranged inside and the box has electrical safety against external rain or moisture. As shown in Korean Authorized Utility Model No. 418448 (published on June 12, 2006), such an existing electric control box includes: a main body; a cover formed on the main body so as to be opened and closed by an angular motion through a hinge; and a lock that can lock the cover to the main body.

[0003] In addition, as shown in Korean Authorized Utility Model No. 439488 (announced on April 16, 2008), the existing electric control box includes a lock that can lock the cover to the main body. In the above-mentioned existing electric control box, an inner door (innerdoor) is provided on the inner side of the cover, and various lights such as signal lights, switches for controlling electrical signals of the internal control panel, and various instruments such as counters or thermometers are provided on the inner door. The hinge fixed to one side of the control panel (=inner door) includes a blade member, and the blade member is connected and fixed to the lower part of the control panel by combining the hinge joint with the shaft. The above-mentioned hinge joint of the above-mentioned hinge is forcibly inserted into the combining recess by forming a separate combining recess on the main body. The above-mentioned shaft is provided at the end of the main body in a freely rotatable manner, and the above-mentioned main body is formed as a whole at the upper part of the hinge joint. However, according to this existing Technology, the edge of the control panel is separated from the main body and supported by two hinges and two fixings, as shown in Korean Authorized Utility Model No. 442481 (Announced on November 13, 2008), which includes: a support member, fixed to each corner of the main body by bolts; a double door frame, assembled on the upper part of the above-mentioned support members by bolt threads; a double door (equivalent to an inner door), which is arranged in the double door frame in a manner that can be opened and closed by a hinge; and a magnet, on the opposite side of the hinge, which is respectively fixed to the double door and the double door frame to fix the double door when the double door is closed, and the edge of the double door is placed by the above-mentioned double door frame, thereby minimizing the generation of noise, etc., but the above-mentioned utility model is formed by a complex structure in order to set the hinge in the double door frame in a freely rotatable manner, so there are multiple problems such as increased manufacturing time and manufacturing cost, and reduced production efficiency.

[0004] Therefore, as shown in Korean authorized patent No. 2489627 (announced on January 18, 2023), the inventor of the present invention has developed the following technology, which includes: a fixing plate fixed to an insertion groove formed in a door frame, the door frame being fixed to support members fixed to the inner side of the main body by bolts; and a movable member, which is arranged and fixed to the inner door in the insertion groove in a manner that can rotate freely with the fixing plate, and rotates as the inner door is opened and closed. The above technology has been applied for a patent and authorized, but as shown in the above-mentioned authorized utility model No. 442481 and authorized patent No. 2489627, it includes: four support members fixed to the main body in a manner that can be removably fixed by bolts. Four internal corners; a double door frame or door frame, fixed on the upper side of the above-mentioned four supporting members; and a hinge, arranged on the above-mentioned double door frame or door frame. In the above structure, the double door frame or door frame is formed in a quadrilateral frame shape, and is arranged on the upper part of the main body only by being fixed on the supporting members. When used for a long time, the supporting members, double door frame or door frame are frequently separated from the main body and damaged due to the opening and closing of the inner door. The above structure has the following problems. When the inner door is opened and closed, it impacts with the double door frame or door frame and generates noise. In addition, the four supporting members, double door frame or door frame need to be separately molded and assembled with the main body, which requires a lot of manufacturing cost and time. Summary of the invention

[0005] The present invention proposes a new technology to solve many problems of the above-mentioned prior art. The problem to be solved by the present invention is to provide the following inner door setting structure for an electric control box, wherein a rotating hinge is connected to the electric control box body in a manner that allows the inner door to rotate, and a stopper is formed by protruding on the upper side of the rotating piece of the rotating hinge to limit the opening degree of the inner door when opening the inner door, thereby preventing the fixing bolts fixing the inner door and the rotating piece from contacting the body, thereby avoiding damage to the electric control box body and noise generation.

[0006] Furthermore, the above-mentioned present invention provides the following inner door setting structure for an electric control box, in which a setting frame on which the inner door can be set is formed as an integral part when the electric control box body is formed, a setting member and a fixing member are respectively set on the upper part of the front and rear setting frames, a rotating hinge and a fixed handle are respectively set on the upper side of the setting member and the fixing member, and the above-mentioned rotating hinge and fixed handle are set on the inner door, thereby simplifying the structure and improving durability.

[0007] As a specific solution for solving the above-mentioned inventive problem, the present invention constitutes an inner door setting structure for an electric control box, which is characterized in that it includes: a rotating hinge between the main body and the inner door, so that one side of the inner door is connected and set in a rotating manner to open and close the inner door in the main body of the electric control box; and a stopper, which is protrudingly formed on one side of the above-mentioned rotating hinge, and can limit the opening degree of the inner door when the inner door is opened in the main body.

[0008] The above-mentioned present invention is characterized in that it includes: a setting frame, which is formed as a whole with the main body by engraving a specified height from the outside to the inside from the bottom surface of the four corners of the main body, and an internal thread is formed at the upper end; and a fixing member, which is fixed and set with a rotating hinge by combining with a fixing bolt threadedly connected to the internal thread formed on the upper side of the above-mentioned setting frame. In addition, the present invention includes an attachment, which is fixed in the main body by combining with a fixing bolt threadedly connected to the internal thread, and the above-mentioned internal thread is formed on the upper side of the setting frame on the opposite side of the rotating hinge and the fixing member, so that it is attached and fixed when the inner door is closed.

[0009] The feature of the present invention is that it comprises: a fixed plate, which is fixed on one side of the upper part of the fixing member in the above-mentioned rotating hinge by fixing bolts; and a rotating plate, which is combined with the fixed plate on one side in a freely rotatable manner in the rotating hinge, and is combined with the inner door on the other side by combining bolts, so that when the inner door rotates, they will rotate together. In this case, a stopper protrudes outwardly and is formed on one side of the rotating plate. When the inner door rotates a specified angle in the main body, the stopper protruding from the rotating plate contacts the upper part of the fixing member to which the fixed plate is fixed and controls the rotating plate to be unable to rotate further in the fixed plate, thereby preventing the inner door from being further opened.

[0010] The above-mentioned present invention is characterized in that it includes: a rotating coupling hole, which is formed through one side of the fixed plate; and a rotating coupling rod, which is inserted into the rotating coupling hole and freely rotated and is connected to one side of the rotating plate. The above-mentioned rotating coupling hole includes: a small-diameter coupling hole, which has a relatively small inner diameter and is formed on the side inserted into the rotating coupling rod; and a large-diameter coupling hole, which has a relatively large inner diameter and is formed on the opposite side of the small-diameter coupling hole. The above-mentioned rotating coupling rod includes: a connecting part, which has a relatively small outer diameter and is correspondingly connected to the small-diameter coupling hole; a locking part, which has a relatively large outer diameter and is restored to its original state in the large-diameter coupling hole after the front end of the connecting part is reduced along the center and passes through the small-diameter coupling hole; and 1 to 2 cutting parts, which are orthogonal to the center of the rotating coupling rod so that the locking part can be reduced and restored.

[0011] According to the specific technical solution for solving the above-mentioned problem, the inner door setting structure for the electric control box of the present invention provides the following multiple effects: the opening degree of the inner door is controlled by a stopper, the stopper is protruded and formed on a rotating piece that rotates together with the inner door when the inner door is opened, and the rotating piece is formed on a rotating hinge connected to the main body in a manner that allows the inner door of the electric control box to be rotatable, so as to prevent the combining bolts that combine the inner door and the rotating piece from colliding with the main body, thereby preventing damage to the electric control box and blocking noise generation, etc.

[0012] In addition, in the present invention, in order to set the inner door on the main body, a setting frame that is inserted and protruded from the outside to the inside to form an integral whole is set at the four corners of the existing main body, instead of setting the existing supporting parts that are fixed by bolts in a detachable manner at the corners inside the main body. Therefore, the present invention has many expected effects as follows: by simplifying the structure of the electric control box, the manufacturing cost is reduced and the assembly time is shortened, the durability of the four corners of the main body is improved, and the life of the product is extended. When the setting frame is molded as an integral whole on the main body, the four corners outside the main body are inserted to improve the overall beauty of the electric control box, and at the same time, the responsiveness or recognition of the product is improved through the originality of the shape.

[0024] The present invention provides an inner door setting structure for an electric control box, which simplifies the structure for setting the inner door in an electric control box having a double door structure of an outer door and an inner door, and prevents the inner door from opening more than a specified angle.

[0025] like Figure 1 As shown, in the above-mentioned electric control box 1 inner door 12 setting structure of the present invention, the outer door 13 (=cover) is set on one side of the body 11 of the electric control box 1 in a rotating opening and closing manner, and the inner door 12 (=setting plate) of various electrical operating devices is set on one side of the body 11 and is set on the inner side of the outer door 13 in a rotating opening and closing manner. In this case, between the body 11 and the inner door 12, one side of the inner door 12 is connected and set by a rotating hinge 2 in a rotating manner, so that the inner door 12 can be opened and closed in the body 11, as shown in FIG. Figure 1 , Figure 3a and Figure 3b As shown, a stopper 3 is formed on one side of the rotating hinge 2. When the inner door 12 is opened in the body 11, Figure 2 and Figure 4a As shown, the opening degree of the inner door 12 can be limited.

[0026] In the present invention, Figure 3a As shown, the rotating hinge 2 includes: a fixed plate 21, which is fixedly arranged on one side of the upper part of the fixing member 5 by a fixing bolt 42; and a rotating plate 22, one side of which is combined with the fixed plate 21 in a freely rotatable manner, and the other side is combined with the inner door 12 by a combining bolt 23, so that when the inner door 12 rotates, it will rotate together, and a stopper 3 protrudes outwardly and is formed on one side of the rotating plate 22. When the inner door 12 rotates a specified angle in the body 11, the stopper 3 protruding from the rotating plate 22 contacts the upper part of the fixing member 5 to which the fixed plate 21 is fixed and controls the rotating plate 22 to be unable to rotate further in the fixed plate 21, thereby preventing the inner door 12 from being further opened.

[0027] like Figure 3b As shown, in this rotary hinge 2 of the present invention, a rotary coupling hole 26 is formed through one side of the fixed plate 21, and a rotary coupling rod 27 is inserted into the rotary coupling hole 26 and freely rotated and coupled to one side of the rotary plate 22. The rotary coupling hole 26 includes: a small-diameter coupling hole 261, which has a relatively small inner diameter and is formed on the side where the rotary coupling rod 27 is inserted; and a large-diameter coupling hole 262, which has a relatively large inner diameter and is formed on the opposite side of the small-diameter coupling hole 261. The rotary coupling rod 27 includes: a connecting portion 271, which has a relatively small outer diameter and is coupled to the small-diameter coupling hole 261; a locking portion 272, which has a relatively large outer diameter and is restored to its original state in the large-diameter coupling hole 262 after the front end of the connecting portion 271 is reduced along the center and passes through the small-diameter coupling hole 261; and 1 to 2 cutting portions 273, which are orthogonal to the center of the rotary coupling rod 27 so that the locking portion 272 can be reduced and restored.

[0028] In addition, in the fixed plate 21 of the present invention, a blocking protrusion 25 is included at the lower part of the side facing the rotating plate 22. The blocking protrusion 25 protrudes toward the rotating plate 22 and contacts the lower surface of the rotating plate 22, thereby preventing the rotating plate 22 from rotating further downward than the fixed plate 21.

[0029] like Figure 1 and Figure 2 As shown, the present invention includes a mounting frame 4, which is integrally formed with the body 11 by engraving a predetermined height (l) from the outside to the inside of the bottom surface of the four corners of the body 11, and has an internal thread 41 formed at the upper end.

[0030] The mounting brackets 4 formed at the four corners of the body 11 are ultimately used to mount the inner door 12 . When the outer door 13 is opened, the inner threads 41 are exposed.

[0031] like Figure 2 As shown, a pair of mounting brackets 4 formed on one side of the main body 11 are formed on the upper side thereof. Figures 4a to 4c The fixing member 5 shown in the figure is fixed and arranged to rotate the hinge 2 by means of a fixing bolt 42 threadedly connected to an internal thread 41 formed on the upper side of the setting frame 4. Figure 2 As shown, a pair of mounting brackets 4 are formed on the opposite side of the main body 11 where the fixing member 5 is provided. Figure 5a to Figure 5b The attachment 6 shown is fixed in the body 11 by a fixing bolt 42 threadedly connected to an internal thread 41 formed on the upper side of the setting frame 4 on the opposite side of the rotating hinge 2 and the fixing member 5, so that it is attached and fixed when the inner door 12 is closed.

[0032] The fixing member 5 is formed as a whole by an insertion groove portion 51, a bearing portion 52 and an insertion fixing portion 53. The insertion groove portion 51 has an insertion groove 511. When the fixing bolt 42 is inserted and threadedly connected to the internal thread 41 of the setting frame 4, the insertion groove 511 is inserted into the head of the fixing bolt 42. On one side of the insertion groove portion 51, the bearing portion 52 protrudes toward the fixing member 5 of the setting frame 4 combined on one side and supports the rotating piece 22 of the rotating hinge 2. When the inner door 12 is opened, the rotating piece 22 will rotate and achieve surface contact with the stopper 3 provided on itself and be supported. In the insertion groove portion 51 and the bearing portion 52, the insertion fixing portion 53 protrudes toward the attachment member 6 on the opposite side, inserts and fixes the bearing protrusion 24 protruding toward the lower part of the fixing piece 21 of the rotating hinge 2 and the blocking protrusion 25 protruding in a manner of blocking the rotation of the rotating piece 22, thereby improving the strength of the connection.

[0033] The above-mentioned attachment 6 includes: a movable attachment 61, which is protruding downwardly and arranged on the opposite side of the inner door 12 where the rotating hinge 2 is arranged in a manner corresponding to the handle 14, and the movable attachment 61 is composed of or attached to the lower head of the bolt 15 that fixes the handle 14 to the inner door 12; an attachment through hole 62, which protrudes inwardly and is formed on one side of the attachment 6 and is formed through the top and bottom to facilitate the insertion of the movable attachment 61; and a fixed attachment 63, which is fixedly arranged at the lower end of the attachment through hole 62 and is used to remove the movable attachment 61 inserted into the attachment through hole 62 by magnetic force.

[0034] As described above, a portion of the upper side of the mounting frame 4 formed integrally with the main body 11 is formed as follows: Figure 6 The coupling member 7 shown in the figure is formed with an upwardly open internal thread 41 for threaded connection with the fixing bolt 42. The above-mentioned coupling member 7 is combined with the fixing member 5 and the attachment member 6 at the upper part. The above-mentioned coupling member 7 includes an upper coupling body 71 which is circular in plane at the upper part, and a lower coupling body 72 which is polygonal in plane at the lower part. The fixing member 5 or the attachment member 6 arranged on the upper part of the setting frame 4 is correspondingly combined with the lower coupling body 72 without shaking left and right. The fixing member 5 or the attachment member 6 is simultaneously combined with the upper coupling body 71 and the lower coupling body 72 without shaking up and down, thereby improving the durability of the combination.

[0035] In the present invention, in addition to the above-mentioned setting frame 4, an insertion portion 8 is also formed. The above-mentioned insertion portion 8 protrudes from the upper part of the setting frame 4 by positive engraving from the inside to the outside and is formed as a whole with the main body 11 along the opposite direction of the setting frame 4. The above-mentioned insertion portion 8 includes an insertion groove 81. When the fixing member 5 or the attachment member 6 is set on the upper side of the setting frame 4, one side corner of the fixing member 5 or the attachment member 6 is formed corresponding to the two side surfaces of the corresponding corner, so that it can be inserted and combined from the top, and the fixing member 5 or the attachment member 6 is combined correspondingly inside and outside together with the combining member 7, so that the fixing member 5 or the attachment member 6 can be accurately combined without shaking at the upper part of the setting frame 4. When the fixing bolt 42 is threadedly connected with the internal thread 41 of the combining member 7, it is more firmly combined and fixed. Therefore, the corners of the main body 11 are formed so that the lower negative engraved setting frame 4 and the upper positive engraved insertion portion 8 have opposite directions, so that the durability can be further doubled.

[0036] And, if Figure 1 , Figure 2 and Figure 6 As shown, in the above-mentioned setting frame 4 of the present invention, when the corners of the body 11 are formed in an intaglio manner, the middle flat surface portion can be configured to be flatter inside at a predetermined distance interval from both ends so that the bent end portion in the body 11 is inserted further inside. As another example, Figure 7a and Figure 7bAs shown, when the corners of the body 11 are formed in an intaglio manner, the middle flat surface portion may also be configured to be flat in the entirety between the two end portions so that it is consistent with the two end portions bent in the body 11 .

[0037] The inner door setting structure for the electric control box of the present invention has the following effects: in the body 11, a stopper 3 is provided on one side of the rotating piece 22 of the rotating hinge 2 connected to the inner door 12 in a rotating opening and closing manner, such as Figure 2 and Figure 4b As shown, when the inner door 12 is opened, the rotating piece 22 will rotate and make the stopper 3 protruding to one side contact with the bearing portion 52 of the fixing member 5, so that the inner door 12 and the rotating piece 22 rotate around the rotating coupling rod 27 inserted into the rotating coupling hole 26 of the fixing piece 21 and then stop, and the connecting bolt 23 fixing the inner door 12 and the rotating piece 22 protrudes to the upper side of the inner door 12, thereby preventing collision with the main body 11, thereby blocking the generation of noise and minimizing damage to the main body 11, the inner door 12 and the connecting bolt 23.

[0038] In addition, the present invention has the following multiple effects. The setting frame 4 is engraved on the four corners of the main body 11 so that the fixing part 5 of the rotating hinge 2 and the attachment 6 of the fixed attachment 63 can be fixed to the main body 11 by fixing bolts 42 respectively. The rotating hinge 2 is used to connect the inner door 12 to the main body 11 in a rotating manner. The attachment 6 is attached with a movable attachment 61 in a manner that is attached and fixed when the inner door 12 is closed, so that the structure of the insertion part 8 engraved on the four corners of the upper part of the setting frame 4 and the upper and lower upper combination bodies 71 and lower combination bodies 72 of the upper combination member 7 of the setting frame 4 are more firmly combined with the fixing part 5 and the attachment 6 after being assembled, and the durability of the combination can be significantly improved.

[0039] As described above, the most preferred embodiments of the present invention are described in the detailed description of the present invention, but various modified embodiments can be performed without departing from the technical scope of the present invention. Therefore, the protection scope of the present invention is not limited to the above-mentioned embodiments, and the technologies within the scope of protection claimed by the invention and the equivalent technical solutions of these technologies should also be deemed to fall within the protection scope of the present invention.
