Description

Door apparatus for distribution board of rotation angle fixing type

The present invention relates to a rotation angle fixed distribution panel door device, and more particularly, to a rotation angle fixed distribution panel door device in which the state in which the door is opened is stably supported.

In general, the distribution panel is used to install a distribution panel on which a switch and the like of each branch circuit are installed on a wall, and is provided with a door that can be opened and closed in order to check the state of an earth leakage breaker or a circuit breaker.

In detail, the conventional distribution panel has a rectangular box having one side open, and includes a buried box having an installation space therein, various internal devices such as an earth leakage circuit breaker installed and fixed in the buried box, and a door for opening and closing the front of the buried box. Include. That is, it prevents the occurrence of an electric shock by blocking the exposure of the internal device installed in the distribution panel through the door to the outside. Here, one end of the door is connected to one outside of the buried box through a hinge, the door is opened and opened through a hinge connected along each upper edge to facilitate repair or replacement parts in the open state. .

At this time, in order to inspect or repair / replace a part such as a switch, the open state of the door should be restrained. Therefore, the torsion spring or the plate spring bent at a predetermined angle is interposed in the hinge portion so that the door is rotated upward to support the open state. That is, when the door is closed, the torsion spring or the leaf spring is compressed, and the bite or latch is fixed between the lower outer portion of the buried box and the lower end of the door. Then, when the bite or locking between the buried box and the door is released, the door is opened while the hinge is rotated upward through the resilience of the torsion spring or the leaf spring.

However, since conventional torsion springs or leaf springs are produced in a state where the bending angle is already collectively determined at the time of manufacture, it is difficult for the user to arbitrarily adjust the opening angle of the door. In addition, the restraining force applied in the state in which the door is closed and the direction in which the load of the door is applied are the same as the direction in which the torsion spring or the leaf spring is pressurized. For this reason, there is a problem in that the opening angle is further narrowed when a compressive force is continuously applied to the torsion spring or the leaf spring, or when the load of the door is applied in correspondence to the direction of compression and restoration in the open state.

Furthermore, when the door is opened, the torsion spring or the leaf spring has a strong elasticity, or when the bite or the locking force between the buried box and the door is weak, there is a problem in that the door is opened as if it bounces due to the strong elasticity. For this reason, there is a problem that the user is injured when the door is opened or damaged while an impact is applied to the door.

In detail, the first hinge hole 42 is formed to have an inner diameter that is equal to or larger than the diameter of one end 32 of the hinge shaft portion 30 but smaller than the diameter of the spaced step portion 31. Through this, when the door link portion 40 is inserted into one end 32 of the hinge shaft portion 30, an outer edge of the first hinge hole 42 is formed on one step of the stepped portion 31. The position is locked. In addition, the inner circumference of the first hinge hole 42 is preferably formed with a first constraining surface 44 which is in surface contact with the one side decut surface portion 34. When the door link part 40 fixed to the door fixing part 21 is rotated when the door plate 20 is opened, one end 32 of the hinge shaft part 30 is rotated by the first hinge. It is axially rotated in conjunction with the mold by being constrained by the hole 42.

In this case, it is preferable that the stop ring 36 is provided to restrain the state in which one end 32 of the hinge shaft part 30 is fastened to the door link part 40. In detail, one end 32 of the hinge shaft portion 30 is formed with a restraint groove 32a at a position spaced apart from one surface of the spaced step portion 31 to one side corresponding to the thickness of the first fastening end 40b. do. The stop ring 36 is fitted into the restraint groove 32a in a state where one end 32 of the hinge shaft part 30 is inserted into the first hinge hole 42. Here, the stop ring 36 is formed in a ring shape in which one side of the circumferential direction is cut, and is easily fitted into the restraint groove 32a as the inner diameter is smaller than the diameter of one end 32 of the hinge shaft portion 30. Can be combined.

Here, in the present invention, the door link unit 40 and the frame link unit 50 to be described later are fastened to the hinge shaft unit 30 through the stop ring 36 and the fixing unit 70 to be described below. The state is constrained. At this time, the stop ring 36 is only fitted to the restraint groove 32a, and the fixing means 70 is only screwed to the screw thread 33a, so that separation and reassembly are easy. Through this, the ease of assembly and replacement of parts of the distribution panel door device 100 can be significantly improved. Further, by adjusting the position where the fixing means 70 is screwed to the screw 33a, it is possible to adjust the force of the shot force of the shot pressure unit 80 to be described later. Therefore, while the door plate 20 is smoothly opened and closed, the rotational angle may provide a force for applying a force such that the rotation angle may be firmly frictionally restrained.

On the other hand, the frame link unit 50 is formed with a second fixing end 50b, the other end of which is fixed to the frame fixing part 11 through a fastening screw or the like. Then, one end bent from the second fixed end 50b is formed as a second fastening end 50a. That is, it is understood that one end of the frame link unit 50 and the second fastening end 50a have the same meaning, and the other end of the frame link unit 50 and the second fixing end 50b have the same meaning. desirable. In this case, the frame link unit 50 is disposed such that the second fastening end 50a is orthogonal to the hinge shaft part 30, and the second fixing end 50b is formed on one surface of the frame fixing part 11. It is desirable to understand that the surface is bent at an angle that can be fixed. Here, the second fastening end 50a is formed with a rotation hole 53 through which the other end 33 of the hinge shaft part 30 is fastened to penetrate in the axial direction. In addition, the other surface 50c of the second fastening end 50a is preferably formed with an embossed groove 51 integrally recessed in one direction.

In detail, the rotation hole 53 is formed to have an inner diameter exceeding the diameter of the other end 33 of the hinge shaft portion 30 but smaller than the diameter of the separation step portion 31. Through this, when the other end 33 of the hinge shaft part 30 is inserted into the frame link part 50, the outer portion of the rotation hole 53 is locked to the other surface of the stepped part 31 which is stepped and extended. The position is constrained. Furthermore, since the separation step portion 31 is formed in a cylindrical shape extending to a predetermined length, the first fastening end 40b and the second fastening end 50a are disposed to face each other, but the separation step 31 Can be spaced apart by an extended length of. As a result, the frictional interference between the door link unit 40 and the frame link unit 50 is minimized during the hinge rotation of the distribution panel door apparatus 100, thereby significantly improving driving reliability.

At this time, it is preferable that the rotating hole 53 is formed in a circular cross section. That is, when the door plate 20 is opened or closed, the hinge shaft part 30 is freely rotated inside the rotation hole 53, and rotational force is not transmitted to the frame link part 50. On the other hand, parts which are contacted and restrained by contact with the decut surface parts 34 and 35, such as the door link part 40 and the emboss pressing plate 60, which will be described later, are interlocked and rotated through the hinge shaft part 30.

On the other hand, the embossing plate 60 is provided on the other surface 50c of the second fastening end (50a), the second hinge hole (63) in the central portion so that the other end 33 of the hinge shaft portion (30) is inserted It is formed through the axial direction. Here, the second hinge hole 63 may be formed to be the same as or exceed the diameter of the other end 33 of the hinge shaft portion 30, the second peripheral surface in surface contact with the other decut surface portion 35 on the inner circumference It is preferable that 65 is formed. That is, the second hinge hole 63 may be formed in substantially the same shape as the first hinge hole 42. Accordingly, the emboss pressure plate 60 is also interlocked and rotated through the hinge shaft 30 which is axially rotated in conjunction with the door link unit 40 when the door plate 20 is opened.

In this case, it is preferable that one side of the embossing plate 60 protrudes in one direction from the emboss protrusion 61 selectively inserted into or withdrawn from the emboss groove 51 according to the rotation angle of the door plate 20. In detail, the embossed projection 61 is inserted into the embossed groove 51 in the closed state of the door plate 20, and the embossed projection from the embossed groove 51 when the door plate 20 is rotated in the open direction. 61 is withdrawn. At this time, the drawn embossed projection 61 is frictionally pressed to the other surface 50c of the second fastening end 50a through the shot force of the shot pressurizing portion 80 to be described later, through which the door plate 20 The rotation angle of) may be constrained. That is, the door plate 20 is rotated in the opening direction, while the rotation operation force is lost and at the same time the embossed projection 61 is frictionally pressed against the other surface 50c of the second fastening end 50a through the shot force. The open state can be maintained.

Here, the embossed groove 51 is preferably formed as a rounded curved inclined surface (51a) of the cross-sectional shape of the front and rear edges corresponding to the rotational direction of the hinge shaft portion (30). At this time, the front and rear edges of the emboss groove 51 is between the emboss groove 51 and the other surface 50c of the second fastening end 50a intersecting the rotational trajectory of the emboss protrusion 61. It is preferable to understand the boundary.

In addition, the embossing plate 60 may be formed at the same time by pressing the second hinge hole 63 and the embossing projection 61 including the second confining surface (65). In detail, the emboss pressure plate 60 is a metal plate is inserted between the outer punching portion for forming the outer mold and the inner mold for forming the second hinge hole 63, the press mold is moved vertically It is formed by cutting through the pressure applied. In this case, the press mold further includes a projection protruding to one side to process the embossing projection (61). Therefore, the embossing plate 60 is punched into a donut shape through the press mold and the embossing protrusion 61 is pressed to protrude to one side.

Furthermore, the emboss pressure plate 60 is a simple method of punching through a press mold densely arranged such that one mold unit including the outer punching part, the inner punching part and the protrusion pressing part has a minimum separation distance. Is manufactured. Through this, it can be cut and molded in large quantities at the same time in one press processing, while improving productivity, economical efficiency can be remarkably improved since scrap generated after processing is minimized. In addition, since no additional processing is required, manufacturing convenience can be significantly improved.

In addition, as the metal plate is stretched through the pressing force of the protruding pressure portion during press processing, the cross-sectional shape of the edge 61a formed by protruding the emboss protrusion 61 may be naturally rounded. Accordingly, the embossed projection 61 may be moved while being smoothly slid through the rounded cross-sectional shapes of the respective edges 51a and 61a when being pulled out of the embossed groove 51. Through this, when the embossed projection 61 is inserted into the embossed groove 51, the hinge structure is not damaged due to the impact being applied while being vertically inserted vertically due to the depth of depression w1 of the embossed groove 51. To prevent it. In addition, since the embossed projection 61 and the embossed groove 51 are prevented from being caught between steps generated when the embossed projection 61 and the embossed groove 51 are protruded and recessed, a smooth operation feeling can be provided.

At this time, when the embossing plate 60 is pressed by the press working, when the embossing projection 61 protrudes to one side, the other side thereof may be recessed to function as a friction damping groove 62. In this case, the friction damping groove 62 adjusts the shot force applied through the shot force pressing portion 80 as the direct contact area with the shot force pressing portion 80 is reduced. That is, even if the other surface of the emboss pressure plate 60 is disposed to face the one surface of the shot force pressing unit 80 as a whole, an area directly contacting the surface through the friction damping groove 62 may be reduced. Through this, the friction between the other surface 50c of the second fastening end 50a and the emboss pressure plate 60 may be minimized while increasing the frictional force due to the shot force. Therefore, the door plate 20, which is provided at a light weight, is smoothly operated without exerting excessive force during opening and closing operations, thereby improving the opening and closing operation feeling, and preventing excessive wear between the opposing surfaces that are rotated and rubbed.

In addition, the emboss groove 51 is formed symmetrically in a pair around the rotation hole 53, the emboss projection 61 is inserted into each of the emboss groove 51, the second hinge hole 63 It is preferable that the pairs are symmetrically formed about the center. Through this, the pair of embossed projections 61 are inserted into the pair of embossed grooves 51 in the closed state of the door plate 20, respectively, and the door plate 20 is arbitrarily rotated open by external vibration or impact. Can be prevented. In addition, the door plate 20 is rotated as the pair of embossed projections 61 are frictionally pressed against the other surface 50c of the second fastening end 50a in the open state of the door plate 20. The open state can be firmly and stably friction restrained.

Furthermore, the inner space in which the embossed groove 51 is recessed is preferably formed larger than the protruding volume of the embossed protrusion 61. That is, a gap is formed between the inner surface of the emboss groove 51 and the outer surface of the emboss protrusion 61 in the state where the emboss protrusion 61 is inserted into the emboss groove 51. As a result, one surface of the emboss pressure plate 60 and the other surface of the second fastening end 50a are in surface contact with the emboss protrusion 61 inserted into the emboss groove 51, and thus, the predetermined friction force. The closed state of the door plate 20 can be fixed more stably.

In addition, the first confinement surface 44 and the second confinement surface 65 are preferably formed to be aligned with each of the embossed projections 61. That is, the protruding position of the embossed projection 61 is set to a position that can be inserted into the embossed groove 51 in the closed state of the door plate 20. In addition, the predetermined protrusion position of the embossing protrusion 61 and the first constraining surface 44 and the second constraining surface 65 are preferably formed to be arranged side by side. Therefore, the distance between each inner circumferential side end portion of the embossed projection 61 adjacent to the second hinge hole 63 and the second confining surface 65 can be set to the maximum. By doing so, when the emboss pressure plate 60 is press-processed, as the emboss protrusion 61 and the second hinge hole 63 are spaced apart at the maximum interval, the shape of the part is clearly processed so that the defective rate may be minimized during production. Can be.

On the other hand, the fixing means 70 is screwed to the screw thread (33a) formed on the other end 33 of the hinge shaft portion (30). In addition, the bullet pressing unit 80 is interposed between the embossing pressure plate 60 and the fixing means 70, but provides the shot pressure in the axial direction to the embossing pressure plate (60). That is, the embossed projection 61 may be firmly frictionally pressed to the other surface 50c of the second fastening end 50a through the shot force of the shot pressurizing portion 80 in the open state of the door plate 20. Can be. Furthermore, as the other side of the shot force pressing unit 80 is fixed through the fixing means 70, the shot force may be substantially provided to one side of the hinge structure.

In this case, it is preferable that the shot force pressing portion 80 includes a shaft spring portion 81 and a pair of reinforcing washers 82 and 83. In detail, the shaft spring portion 81 is provided with an elastic body that is rotationally bent to surround the outer circumference of the other end 33 of the hinge shaft portion 30 so that both ends thereof are spaced in the axial direction. In this case, wrapping the outer circumference does not mean contacting the outer surface of the other end 33 of the hinge shaft portion 30, but is understood to be a shape that is spaced apart from the outer surface of the other end 33 of the hinge shaft portion in a radially outward direction. desirable.

Furthermore, the shaft spring portion 81 may be provided as a spring washer. The spring washer is provided in a ring shape, and functions as an elastic body as it is twisted so that both ends cut in one circumferential direction thereof are spaced apart in the axial direction. That is, it is preferable to understand that the shot force of the shot force pressing unit 80 is substantially the shot force applied through the shaft spring portion 81. In this case, the spring washer may have a shape substantially similar to that of a single rotated spring, but may be formed to be more rigid than a thin coil spring. Therefore, while the compaction pressurizing unit 80 is provided compactly, it is possible to receive a pressurizing force capable of stably supporting the load of the door plate 20.

In addition, the reinforcing washers 82 and 83 are interposed so as to be in contact with the other surface of the emboss pressure plate 60 and one surface of the fixing means 70 so that one end and the other end of the shaft spring portion 81 are in contact with each other. At this time, it is preferable that the screw engagement position of the fixing means 70 is adjusted so that the clearance between the reinforcing washers 82 and 83 and the shaft spring portion 81 is prevented.

Here, the reinforcing washers (82, 83) has an outer diameter larger than the overall outer diameter of the shaft spring portion 81 and the cross-sectional outer profile of the fixing means 70, the inner diameter of the entire shaft spring portion 81 It is formed in a donut shape exceeding the inner circumference diameter and the diameter of the other end 33 of the hinge shaft portion 30. In addition, it is preferable that the central portion penetrates in a circular shape so as to freely rotate while the hinge shaft portion 30 is penetrated. Therefore, even if the shaft spring portion 81 is compressed or restored in the axial direction, the fastened position can be restrained stably. In addition, since one end of the shaft spring portion 81 is introduced into the friction damping groove 62, the driving force of the shaft may be reduced or the twist of the emboss pressure plate 60 may be prevented, thereby significantly improving driving reliability. have.

Through this, the distribution panel door device 100, as shown in Figure 5a and 5c, the embossed projection 61 is inserted into the embossed groove 51 in the closed state of the door plate 30. At this time, the emboss protrusion 61 continuously presses and supports the other surface 50c of the second fastening end 50a by the embossing pressure plate 60 of the embossing pressurizing unit 80. The state inserted in 51 is restrained. Therefore, the door plate 20 can be prevented from being arbitrarily rotated and opened. In addition, since the emboss protrusion 61 is formed smaller than the recessed inner space of the emboss groove 51, one surface of the emboss pressure plate 60 and the other surface 50c of the second fastening end 50a are in surface contact. The closed state can be stably supported by the frictional force. Through this, even if there is no separate configuration such as a push button or a locking means, the closed state of the door plate 20 can be stably maintained.

In addition, the emboss groove 51 is preferably formed at a position spaced in rotation inclined at a predetermined angle (d) in the closing direction from the predetermined reference line (c). In this case, the predetermined angle (d) may be set in the range of 1 to 3 °.

In detail, since the frame link unit 50 is fixed to the distribution panel frame 10 installed on the wall, the position where the embossed groove 51 is recessed is fixed regardless of opening and closing the door plate 20. . In this case, since the emboss groove 51 is formed at a predetermined angle d in a closing direction from a reference line c, for example, the reference line parallel to the wall surface direction, the emboss protrusion 61 formed on the emboss pressure plate 60. ) Is further rotated in the closing direction to be inserted into the emboss groove 51.

In this case, since the shot force of the shot force pressing unit 80 is continuously transmitted in one direction, the state in which the emboss protrusion 61 is rotated in the closing direction to be inserted into the emboss groove 51 may be stably fixed. . In addition, the door link unit 40 fastened to be interlocked and rotated through the hinge shaft unit 30 and the door plate 20 to which the door link unit 40 is fixed are closed in correspondence with the angle d. Is further rotated to the side. Therefore, in the closed state of the door plate 20, the lower end of the door plate 20 may be rotated by the angle d toward the lower end of the distribution panel frame 10. Accordingly, the play may be substantially removed between the door plate 20 and the opposing surface of the distribution panel frame 10, and the interior of the distribution panel may be sealed. Through this, safety accidents such as short circuits due to the introduction of foreign matter such as rainwater, moisture, or dust into the distribution panel are prevented in advance, thereby improving safety.

In addition, a protruding edge may be formed on one surface of the door plate 20 and the distribution box frame 10 that face each other, and an accommodation groove into which the protruding edge is inserted may be formed on the other surface. Through this, it is possible to further prevent the play between the door plate 20 and the opposite surface of the distribution panel frame 10 in the closed state of the door plate 20.

In addition, the hinge structure included in the distribution panel door device 100 is provided with a combination of components having a simple yet simple shape. That is, the door link unit 40 and the frame link unit 50 may be formed by pressing to fasten the fastening hole to which the fastening screw is fastened, the first hinge hole 42, and the rotation hole 53. It can be easily manufactured by simply bending the metal plate after cutting. In addition, the embossing plate 60 may be manufactured by mass processing so that the embossing protrusion 61 and the friction damping groove 62 are simultaneously formed while being punched into a donut shape. In addition, since the hinge shaft portion 30, the fixing means 70, and the bullet pressurizing portion 80 can use a commercially available mass production product, it is possible to reduce the difficulty of assembling parts and to significantly reduce manufacturing costs.

6A and 6B, when the door plate 20 is rotated in the opening direction r1 to open upward, the door link part 40, the hinge shaft part 30, and the emboss pressure plate 60 are rotated. ) Is interlocked. At this time, since the frame link unit 50 is fixed to the distribution panel frame, the emboss protrusion 61 is rotated about the hinge shaft unit 30 and drawn out from the emboss groove 51.

Here, since the curved inclined surface (51a) of the embossed groove 51 and the rounded edge (61a) of the embossed projection 61 is moved smoothly, the operation feeling can be remarkably improved when opening and closing. In addition, since the embossed projection 61 is formed to be smaller than the recessed inner space of the embossed groove 51, the contact between the embossed projection 61 and the embossed groove 51 is not in total contact with the line contact or the minimum surface contact It is rotated while being supported. Through this, wear due to the rotational friction between the parts included in the hinge structure is minimized, so durability can be significantly improved.

At this time, when the opening operation of the door plate 20 is stopped in the state in which the door plate 20 is upwardly opened at a predetermined angle, the angle of rotation between the emboss protrusion 61 and the pair of emboss grooves 51 is increased. The friction is pressed to the position moved correspondingly. In addition, the shaft spring portion 81 is the embossed projection 61 is drawn out from the embossed groove 61 and in contact with the other surface 50c of the second fastening end 50a while the emboss pressure plate 60 is struck. It is compressed by the interval moved to the side. In addition, the projecting outer surface of the embossing protrusion 61 is provided on the other surface 50c of the second fastening end 50a through a shot force acting as a repulsive force against the compressive force generated while the shaft spring portion 81 is compressed. The rotated position is constrained by pressing contact. On the other hand, it is preferable that the arrow denoted by p in Figure 6a indicates the direction in which the shot force applied through the shaft spring portion 81 is applied.

In addition, the protruding outer surface of the embossing protrusion 61 is preferably formed as a flat surface so as to be in surface contact with the other surface 50c of the second fastening end 50a. Therefore, the state in which the embossed projection 61 is pressed and rubbed and firmly supported by the elastic force of the shaft spring portion 81 is firmly supported, so that the rotation angle of the door plate 20 can be stably maintained. have.

At this time, the panel panel door device 100 has an upward open state of the door plate 30 is a friction force between the other end of the embossed projection 61 and the frame link unit 50 and the shot force between the bullet pressing unit 80 It is supported by pressing force. Accordingly, the rotation angle may be constrained while the friction force and the shot force are applied to the position where the emboss protrusion 61 is stopped at the moment when the user's operation force for rotating the door plate 20 is removed. As such, the present invention can rotate the door plate 20 at various angles as necessary. In addition, as long as the emboss protrusion 61 is drawn out of the emboss groove 51 at any angle, the open state of the door plate 20 is fixed while being frictionally restrained on the other surface 50c of the second fastening end 50a. The ease of use can be significantly improved.

In addition, the load direction of the upwardly open door plate 20 and the direction in which the shot force pressing portion 80 is compressed are formed differently. That is, the force of the bullet pressing unit 80 is applied a compressive force as much as the height of the protruding height of the embossing projection 61 is not directly applied to the load of the door plate 20. Therefore, since the problems such as the elastic deterioration of the shot force pressing unit 80 due to the load of the door plate 20 is solved in recent years, the service life of the distribution panel door device 100 can be significantly extended.

Further, the other surface 50c of the second fastening end 50a and the protruding outer surface of the embossing protrusion 61 are formed in a plane perpendicular to the axial direction of the hinge shaft portion 30. Therefore, when the emboss pressure plate 60 is pressed toward the second fastening end 50a by the elastic force pressing force of the carbushing pressing part 80, the other surface of the second fastening end 50a is embossed. Slip along the 50c) can be prevented. This prevents the door plate 20 from being arbitrarily rotated down until the user closes the door plate 20.

On the other hand, Figures 7a and 7b is an exemplary view showing a modification of the hinge structure in the rotation angle fixed distribution panel door apparatus according to an embodiment of the present invention. In this modification, since the basic configuration except for the frame link unit 150 is the same as the above-described embodiment, detailed description of the same configuration will be omitted.

As shown in FIGS. 7A and 7B, an uneven portion 150d may be formed at the other end of the frame link unit 150, that is, the other surface of the second fastening end 150a. That is, as the friction coefficient increases when the frictional pressure with the protruding outer surface of the embossed projection 61 is increased through the uneven portion 150d, the door plate 20 can stably support the load in an open state. have.

In addition, in order to support a load of the door plate 20 which is hinged and rotated upward, an auxiliary emboss groove 155 may be formed between the pair of emboss grooves 151. At this time, the depression depth w1 of the auxiliary emboss groove 155 may be recessed to a depth smaller than the depression depth w1 of the emboss groove 151.

In detail, when the door plate 20 is opened, the emboss protrusion 61 is drawn out from the emboss groove 151 and slides in the opening direction r1 along the other surface of the second fastening end 150a. In addition, when the rotation operation force for opening and closing the door plate 20 is lost, the position rotated through the shot force of the shaft spring portion 81 is frictionally restrained. At this time, even if the embossing projection 61 slides in the closing direction r2 along the other surface of the second fastening end 150a due to the load of the door plate 20, the auxiliary emboss groove 155 is rotated downward. It may be recessed and locked to the stepped end 155a.

In this case, since the auxiliary emboss groove 155 is recessed to a smaller depth than the emboss groove 151, the impact force of the shaft spring 81 may be continuously applied to the emboss pressure plate 60. Therefore, since the state in which the emboss protrusion 61 is locked to the stepped end 155a of the auxiliary emboss groove 155 is stably supported, the door plate 20 is loaded with load before the closing operation force of the user is applied. Due to this it can be prevented to rotate arbitrarily downwards over a certain angle.

In this case, the auxiliary emboss groove 155 has a stepped shape in which a stepped end 155a is formed by recessing the closing direction r2 side of one of the positions between the pair of emboss grooves 151 as shown in the drawing. It can be formed as. Of course, in some cases, the auxiliary emboss groove 155 may be formed in a concave groove shape having an edge recessed in both the closing direction r2 and the opening direction r1.

As described above, the present invention is a carbush generated by the repulsive force while the carbush pressing unit 80 is compressed by the protruding thickness of the embossed projection (61) drawn out from the emboss groove 51 during the rotation operation of the door plate 20 The pressing force and the friction force between the frame link unit 50 and the embossing protrusion 61 simultaneously act. Through this, the rotation angle of the door plate 20 can be stably fixed and maintained in the open position.

At this time, since the embossing plate 60 is produced by the punching and the press working is performed at the same time the pressing pressure for forming the embossing projection 61 is simplified the manufacturing process. In addition, through the friction damping groove 62 is automatically formed in the other surface as the embossing projections 61 protrude to reduce excessive friction between components. Through this, since the door plate 20 which is provided at a light weight is prevented from being stiffly rotated, the opening and closing operation can be significantly improved.

Furthermore, when the embossing plate 60 is pressed, the edge cross-sectional shape of the embossing protrusion 61 is naturally rounded through the stretching of the metal plate, so that smooth slide movement can be induced. Therefore, the opening and closing operation of the door plate 20 may be prevented from being squeezed due to protruding / depressed step during insertion and withdrawal of the embossing protrusion 61, thereby significantly improving the opening and closing operation.

In addition, the embossed groove 51 is formed at a position spaced apart from the predetermined reference line c to be inclined rotationally at a predetermined angle in the closing direction. Accordingly, when the embossing projection 61 is inserted into the embossing groove 51, the lower end of the door plate 20 may be pressed and rotated toward the distribution panel frame 10 to be in close contact with no play. Through this, safety may be remarkably improved by preventing the inflow of moisture or dust into the distribution panel.

In addition, the auxiliary emboss groove 155 recessed to a small depth between the pair of emboss grooves 151 even when the emboss protrusion 61 is slid downward in the closing direction r2 due to the load of the door plate 20. It may be locked to the stepped end (155a) of. Therefore, the door plate 20 may be prevented from rotating downward arbitrarily over a predetermined angle, thereby further improving safety.

In addition, since the door plate 20 is made of synthetic resin and is provided with light weight while having insulation, a large elastic force and friction force are not required to fix the rotation angle while supporting the load. Through this, the parts can be simplified and simplified, such as having the carbushion pressing unit 80 as a spring washer can be significantly improved manufacturing convenience and economic efficiency.
