[0042] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Please refer to Figure 1 and Figure 2This embodiment provides a flip cover structure, which includes a first connection seat 10, a second connection seat 20 and a connection arm 30; one end of the connection arm 30 is rotatably connected to the first connection seat 10, and the other end is rotatably connected to the second connection seat 20, the first connection seat 10 is used to be fixed to the cover 200 of the distribution box, and the second connection seat 20 is used to be fixed to the cabinet 300 of the distribution box. The flip cover structure can increase the degree of freedom of the cover 200, so that the cover 200 can be flipped in multiple directions, which is convenient for users to operate components in the cabinet 300.

[0044] The above-mentioned first connecting seat 10 is used to be configured on the face cover 200 of the distribution box. One side of the first connecting seat 10 is fixed to the face cover 200, and the other side is rotatably connected to the connecting arm 30. In this way, the first connecting seat 10 can rotate relative to the connecting arm 30, thereby realizing the rotation of the face cover 200 relative to the connecting arm 30. In this way, the angle between the face cover 200 and the connecting arm 30 can be diversified, and the user can flip the face cover 200 according to actual needs to make the setting angle of the face cover 200 and the connecting arm 30 variable.

[0045] One end of the connecting arm 30 is rotatably connected to the first connecting seat 10, and the other end is rotatably connected to the second connecting seat 20. The length of the connecting arm 30 is not specifically limited in this application and can be set according to the positional relationship between the cover 200 and the cabinet body 300 when the cover 200 is opened and closed.

[0046] The second connection base 20 is located at one end of the connection arm 30 away from the first connection base 10, and is rotatably connected to the connection arm 30. In this embodiment, the second connection base 20 is configured to be fixedly connected to the cabinet 300, so that the connection arm 30 rotates relative to the second connection base 20, which can drive the cover 200 to rotate relative to the cabinet 300, thereby realizing the opening and closing of the cover 200 and the cabinet 300.

[0047] It should be noted that the present application sets a connecting arm 30 and a first connecting seat 10 and a second connecting seat 20 that are rotatably connected to the opposite ends of the connecting arm 30, and the first connecting seat 10 and the second connecting seat 20 are respectively fixed on the cover 200 and the cabinet 300. In this way, when the cover 200 of the distribution box needs to be opened, the connecting arm 30 can be driven to rotate relative to the second connecting seat 20. After the cover 200 is opened, the first connecting seat 10 can be driven to rotate relative to the connecting arm 30, so that the angle between the cover 200 and the connecting arm 30 can be changed. Through the above-mentioned setting, the present application can realize the rotation of the cover 200 relative to the connecting arm 30 and the rotation of the connecting arm 30 relative to the cabinet 300. In this way, the degree of freedom of the cover 200 can be increased, so that the cover 200 can be flipped in multiple directions relative to the cabinet 300, and the application scenarios of the distribution box provided with the flip cover structure can be expanded, so that users can operate the components in the cabinet 300 in various scenarios.

[0048] In summary, the flip cover structure provided by the present application includes a first connection seat 10, a second connection seat 20 and a connection arm 30; one end of the connection arm 30 is rotationally connected to the first connection seat 10, and the other end is rotationally connected to the second connection seat 20, the first connection seat 10 is used to be fixed to the cover 200 of the distribution box, and the second connection seat 20 is used to be fixed to the cabinet 300 of the distribution box. The present application sets a connection arm 30 and a first connection seat 10 and a second connection seat 20 that are rotationally connected to the connection arm 30, respectively, so that when it is necessary to open the cover 200 covered on the cabinet 300, the user can drive the connection arm 30 to rotate the connection arm 30 relative to the second connection seat 20; after opening the cover 200, the first connection seat 10 can also be driven to rotate relative to the connection arm 30 as needed, so that the cover 200 fixed to the first connection seat 10 can be rotated relative to the connection arm 30. The present application can increase the degree of freedom of the face cover 200 through the above-mentioned two rotation settings, and realize the face cover 200 to flip in multiple directions relative to the cabinet 300. In this way, the distribution box equipped with the flip cover structure can be used in a variety of scenarios, thereby improving the applicability and facilitating users to operate components in the cabinet 300 in a variety of scenarios.

[0049] Please refer to Figure 3 and Figure 4 Optionally, the first connecting seat 10 includes a first body 11 for fixing to the face cover 200 and a first support 12 connected to the first body 11, and the first support 12 is provided with a first connecting hole 121; the connecting arm 30 is provided with a first mounting hole 31 at one end close to the first connecting seat 10, and the flip cover structure also includes a first rotating shaft 41 passing through the first mounting hole 31 and the first connecting hole 121.

[0050] The first support 12 and the first body 11 may be two parts connected by a connecting structure; of course, the first support 12 and the first body 11 may also be integrally formed.

[0051] The first connecting hole 121 on the first support 12 corresponds to the first mounting hole 31 on the connecting arm 30, and the first rotating shaft 41 is rotatably connected in the first connecting hole 121 and the first mounting hole 31, so that the rotatable connection between the first connecting seat 10 and the connecting arm 30 can be achieved.

[0052] It should be noted that the first mounting hole 31 can be a through hole or a blind hole provided on the connecting arm 30. Similarly, the first connecting hole 121 on the first support 12 can also be a through hole or a blind hole. The present application does not limit the forms of the first mounting hole 31 and the first connecting hole 121.

[0053] Please note that, please refer to Fig.10 When the first mounting hole 31 is a blind hole, a threading hole 35 penetrating along the length direction of the connecting arm 30 may be provided on the connecting arm 30. The threading hole 35 is used for routing the distribution box to avoid bending and exposure of external cables.

[0054] In this embodiment, in order to make the connection between the first connecting seat 10 and the connecting arm 30 more reliable, as shown in FIG. Figure 3 As shown, the first support 12 includes two first supports 12 , which are spaced apart from each other, and one end of the connecting arm 30 close to the first connecting support 10 is located between the two first supports 12 .

[0055] At this time, if Figure 3 As shown, one end of the connecting arm 30 close to the first connecting seat 10 is located between the two first supports 12, the first connecting holes 121 of the two first supports 12 are respectively aligned with the first mounting holes 31 on the connecting arm 30, and the first rotating shaft 41 is penetrated through the two first connecting holes 121 and the first mounting hole 31.

[0056] It should be noted that when the first support 12 includes two, the first mounting holes 31 on the connecting arm 30 can be set to two and both are blind holes. At this time, the first rotating shaft 41 can include two, one of the first rotating shafts 41 is inserted into the first connecting hole 121 of one of the first supports 12 and a first mounting hole 31 of the connecting arm 30, and the other first rotating shaft 41 is inserted into the first connecting hole 121 of the other first support 12 and the other first mounting hole 31 of the connecting arm 30.

[0057] Of course, when there are two first supports 12, the first mounting hole 31 on the connecting arm 30 can also be one and be a through hole. In this case, there can be one first rotating shaft 41, which is inserted into the first mounting hole 31 of the connecting arm 30, and one end of which extends out from one side of the first mounting hole 31 and is inserted into the first connecting hole 121 of one first support 12, and the other end of which extends out from the other side of the first mounting hole 31 and is inserted into the first connecting hole 121 of the other first support 12.

[0058] The first connection hole 121 provided on the first support 12 may be a through hole or a blind hole, and the present application does not impose any specific limitation thereto.

[0059] In order to enable the angle between the first connecting seat 10 and the connecting arm 30 to be suspended and fixed, optionally, a first matching structure is provided on the first support 12, and a second matching structure that is adapted to the shape of the first matching structure is provided on the connecting arm 30. The first matching structure and the second matching structure cooperate with each other to enable the first connecting seat 10 to be radially limited relative to the connecting arm 30.

[0060] That is, the present application sets a first matching structure and a second matching structure, and when the first connecting seat 10 and the connecting arm 30 need to be radially limited, the first matching structure and the second matching structure can be mutually matched to limit. It should be noted that when the first matching structure and the second matching structure are matched, the radial rotation of the first connecting seat 10 and the connecting arm 30 is limited.

[0061] In the first possible implementation, please refer to Figure 4 and Fig.10 The first matching structure includes a first fixing pin 51 and a first pin hole 122 provided on the first support 12; the second matching structure is a second matching piece 32 provided at one end of the connecting arm 30 close to the first connecting seat 10, the first fixing pin 51 is used to pass through the first pin hole 122, and part of the outer wall surface of the first fixing pin 51 is used to limit the second matching piece 32 to limit the first connecting seat 10 radially relative to the connecting arm 30.

[0062] The first pin hole 122 and the first fixing pin 51 can refer to Figure 4 and Fig.10 As shown, the second matching member 32 can refer to Figure 7 and Figure 8 Shown is the first limit groove.

[0063] The first fixing pin 51 is used to be inserted into the first pin hole 122. When the first connecting seat 10 rotates relative to the connecting arm 30 so that the first pin hole 122 on the first connecting seat 10 and the first limiting groove on the connecting arm 30 are aligned and connected, at this time, the first fixing pin 51 is inserted into the first pin hole 122, and the outer wall surface of the first fixing pin 51 can achieve limiting cooperation with the first limiting groove. At this time, the first connecting seat 10 and the connecting arm 30 can be fixed by the first fixing pin 51. In this way, the first connecting seat 10 can achieve radial limitation relative to the connecting arm 30, and the first connecting seat 10 will not be able to rotate relative to the connecting arm 30, that is, the angle between the first connecting seat 10 and the connecting arm 30 is fixed.

[0064] It should be understood that the shape of the above-mentioned first limiting groove should be compatible with the outer wall surface of the first fixing pin 51 on the side close to the first limiting groove, and the specific shape is not limited in this application.

[0065] It should be noted that when the first pin hole 122 on the first connecting seat 10 and the first limiting groove on the connecting arm 30 are aligned and connected, the specific angle between the first connecting seat 10 and the connecting arm 30 is not limited in this application, and those skilled in the art can set it as needed.

[0066] In the second possible implementation, please refer to Fig.11 and Fig.12 The first matching structure includes a first matching piece 81 arranged on the first body 11 and arranged side by side with the first support 12; the second matching structure is a second matching piece 32 arranged at one end of the connecting arm 30 close to the first connecting seat 10, and the first matching piece 81 and the second matching piece 32 are matched in a concave and convex manner to radially limit the first connecting seat 10 relative to the connecting arm 30.

[0067] It should be noted that the first matching piece 81 and the second matching piece 32 may be matched in a concave-convex matching manner. For example, the first matching piece 81 has a concave portion, and the second matching piece 32 has a convex portion; or vice versa. The following mainly uses the example of the first matching piece 81 having a convex portion and the second matching piece 32 having a concave portion for explanation.

[0068] The first matching member 81 is disposed on the first body 11. For example, a mounting groove may be provided on the first body 11, and the first matching member 81 is disposed in the mounting groove. Fig.12 .

[0069] The second matching piece 32 is formed on the connecting arm 30, and the second matching piece 32 may be a third limiting groove, which may be a toothed piece provided on the connecting arm 30, and the gap between two adjacent toothed pieces forms the second matching piece 32. When the first matching piece 81 is inserted into the second matching piece 32 (the convex part of the first matching piece 81 is inserted into the concave part of the second matching piece 32), the first connecting seat 10 can achieve radial limiting relative to the connecting arm 30, and the first connecting seat 10 cannot rotate relative to the connecting arm 30, that is, the angle between the first connecting seat 10 and the connecting arm 30 is fixed.

[0070] The radial limiting of the first connecting seat 10 and the connecting arm 30 can be achieved by any one of the above two implementation methods, and the present application does not make any specific limitation.

[0071] Of course, in order to allow the first connection seat 10 and the connection arm 30 to be fixed at multiple angles, optionally, the second matching piece 32 in the above two implementations can include multiple second matching pieces 32, and the multiple second matching pieces 32 are respectively distributed on the periphery of one end of the connection arm 30 close to the first connection seat 10. In addition, it should be noted that in the second implementation, the second matching piece 32 is an elastic piece.

[0072] In this way, the first connecting seat 10 can be rotated at multiple angles relative to the connecting arm 30 to achieve hovering fixation; the surface cover 200 can be rotated at any angle relative to the connecting arm 30 and can be fixed at multiple angles.

[0073] Among them, the setting positions of the above-mentioned multiple second matching parts 32 can be determined according to the angle between the first connecting seat 10 and the connecting arm 30 corresponding to the commonly used hovering position, and the present application does not make specific restrictions.

[0074] In this embodiment, when the second matching piece 32 in the second implementation manner includes multiple pieces, multiple tooth-shaped pieces can be provided on the connecting arm 30, and the gap between each two adjacent tooth-shaped pieces forms a second matching piece 32, such as Fig.12 shown.

[0075] It should be noted that, taking the cooperation of the second matching piece 32 and the first fixing pin 51 to achieve angle fixing as an example (i.e., the first implementation method), when it is necessary to fix the first connecting seat 10 and the connecting arm 30 at the first angle, the first connecting seat 10 is first rotated so that the first connecting seat 10 corresponds to one of the second matching pieces 32 of the connecting arm 30 (at this time, the angle between the first connecting seat 10 and the connecting arm 30 is the first angle), and then the first fixing pin 51 is inserted into the first pin hole 122 and the second matching piece 32. At this time, the first connecting seat 10 and the connecting arm 30 are fixed. At the first angle; when it is necessary to convert the first connecting seat 10 and the connecting arm 30 from being fixed at the first angle to being fixed at the second angle, first take out the first fixing pin 51, and then rotate the first connecting seat 10 so that the first connecting seat 10 corresponds to the other second matching piece 32 of the connecting arm 30 (at this time, the angle between the first connecting seat 10 and the connecting arm 30 is switched from the first angle to the second angle), and then insert the first fixing pin 51 into the first pin hole 122 and the second matching piece 32. At this time, the first connecting seat 10 and the connecting arm 30 are fixed at the second angle.

[0076] When the second matching piece 32 and the first matching piece 81 are used to cooperate to achieve angle switching (the second implementation method), the first connecting seat 10 can be rotated with the first rotating shaft 41 as the rotating shaft, and the connecting arm 30 can also be rotated to achieve the cooperation between the first matching piece 81 and the second matching piece 32. For example, when the connecting arm 30 is fixed, the first connecting seat 10 can be rotated. At this time, since the first matching piece 81 has an elastic effect, it can be matched with the second matching piece 32 in a concave and convex position-limiting manner under its telescopic deformation; similarly, when the first connecting seat 10 is fixed, the connecting arm 30 can be rotated. In this way, the second matching piece 32 can be driven to rotate together by the connecting arm 30 so that it can conflict with the first matching piece 81 with an elastic effect to rotate and cooperate. The present application can achieve angle switching by rotating the first connecting seat 10 or the connecting arm 30 so that different second matching pieces 32 cooperate with the first matching piece 81.

[0077] Please refer to Figures 5 to 7 Optionally, the second connection base 20 is provided with a second connection hole 21; the end of the connection arm 30 close to the second connection base 20 is provided with a second mounting hole 33, and the flip cover structure further includes a second rotation shaft 42 passing through the second mounting hole 33 and the second connection hole 21. In this way, the second connection base 20 can be rotatably connected with the connection arm 30.

[0078] It should be noted that, similar to the first connecting seat 10, the second connecting hole 21 can include one or two. When the second connecting hole 21 includes one, the second rotating shaft 42 also includes one. The second mounting hole 33 on the connecting arm 30 can be a blind hole or a through hole.

[0079] When there are two second connection holes 21, the two second connection holes 21 are located at opposite sides of the connection arm 30, such as Figure 6 At this time, the second mounting hole 33 on the connecting arm 30 can be a through hole; or two blind holes respectively arranged on opposite sides of the connecting arm 30, one blind hole corresponds to one second connecting hole 21, and the other blind hole corresponds to the other second connecting hole 21. At this time, the second rotating shaft 42 includes two, one second rotating shaft 42 is penetrated in one blind hole and one second connecting hole 21, and the other second rotating shaft 42 is penetrated in the other blind hole and the other second connecting hole 21.

[0080] Please refer to Figure 6 and Figure 7 Optionally, a second pin hole 22 is further provided on the second connecting seat 20, and a second limiting groove 34 is provided at one end of the connecting arm 30 close to the second connecting seat 20. The flip cover structure also includes a second fixing pin 52, which is used to be inserted into the second pin hole 22, and a portion of the outer wall surface of the second fixing pin 52 is used to cooperate with the second limiting groove 34 to limit the connecting arm 30 radially relative to the second connecting seat 20.

[0081] The second pin hole 22 and the second fixing pin 52 can be referred to as Figure 5 and Figure 6 As shown, the second limiting groove 34 can refer to Fig. 9 shown.

[0082] The second fixing pin 52 is used to be inserted into the second pin hole 22. When the connecting arm 30 rotates relative to the second connecting seat 20 so that the second pin hole 22 on the connecting arm 30 and the second limiting groove 34 on the second connecting seat 20 are aligned and connected, at this time, the second fixing pin 52 is inserted into the second pin hole 22, and the outer wall surface of the second fixing pin 52 can be limited by the second limiting groove 34. At this time, the connecting arm 30 can be restricted by the second fixing pin 52, so that the connecting arm 30 cannot rotate relative to the second connecting seat 20 (that is, the connecting arm 30 is radially limited relative to the second connecting seat 20). At this time, the angle between the connecting arm 30 and the second connecting seat 20 is fixed.

[0083] It should be understood that the shape of the second limiting groove 34 should be compatible with the outer wall surface of the second fixing pin 52 on the side close to the second limiting groove 34, and the specific shape is not limited in this application. In this embodiment, the second limiting groove 34 is arc-shaped, such as Fig. 9 shown.

[0084] It should be noted that when the second pin hole 22 on the second connecting seat 20 and the second limiting groove 34 on the connecting arm 30 are connected, the specific angle between the second connecting seat 20 and the connecting arm 30 is not limited in this application, and those skilled in the art can set it as needed. For example, when the second pin hole 22 on the second connecting seat 20 and the second limiting groove 34 on the connecting arm 30 are connected, the angle between the second connecting seat 20 and the connecting arm 30 is set to a commonly used hovering angle of the second connecting seat 20 and the connecting arm 30.

[0085] In order to fix the connecting arm 30 and the second connecting seat 20 at multiple angles, the second latch hole 22 may optionally include multiple second latch holes 22, and the multiple second latch holes 22 may be arranged along the rotation path of the second limiting groove 34. In this way, when the second limiting groove 34 on the connecting arm 30 rotates to dock with any second latch hole 22, the second fixing pin 52 may be inserted to fix the connecting arm 30 at the position corresponding to the second latch hole 22. By providing multiple second latch holes 22, the connecting arm 30 may be suspended at multiple angles.

[0086] Optionally, the flip cover structure further includes a support column 60 for fixing on the cabinet 300, such as Figure 5 and Figure 6 A waist-shaped hole 61 is provided on the support column 60 , and the second connecting seat 20 is fixed in the waist-shaped hole 61 of the support column 60 through a connecting piece 70 .

[0087] The support column 60 is fixed on the cabinet 300 , and the second connection base 20 is fixed on the support column 60 . The second connection base 20 can be fixed to the cabinet 300 through the support column 60 .

[0088] The support column 60 is provided with a waist-shaped hole 61, such as Figure 6 As shown, at this time, the connecting member 70 fixed on the second connecting seat 20 can be selectively fixed at any position of the waist-shaped hole 61. In this way, the fixed position of the second connecting member 70 on the support column 60 can be fine-tuned, and redundant design can be added to improve the process adaptability of the flip cover structure.

[0089] Also, in this embodiment, optionally, a screen may be provided on the cover 200 to facilitate the user to operate facing the screen. The size and specific position of the screen are not specifically limited in this application, as long as the user can operate facing the screen when the cover 200 is opened.

[0090] It should be noted that the screen can be set on the front or back of the cover 200. Exemplarily, when the screen is located on the front of the cover 200, the user can directly operate the screen and control the internal equipment of the distribution box without opening the cover 200; the cover 200 can also be opened and flipped to be substantially parallel to the bottom surface of the distribution box and the screen faces the user (that is, the screen faces the side of the bottom surface facing away from the distribution box after the cover 200 is flipped), which can also facilitate the user to operate facing the screen, and the user can also operate the internal equipment of the distribution box; when the screen is located on the back of the cover 200, the user directly opens the cover 200 (similar to the operation of turning a book) to expose the screen on the cover 200, and the screen and the internal equipment of the distribution box can be operated at the same time.

[0091] Another aspect of the utility model provides a distribution box, which includes a cover 200, a cabinet 300 and at least one of the above-mentioned flip structures, wherein a first connection seat 10 of the flip structure is fixed to the cover 200, and a second connection seat 20 of the flip structure is fixed to the cabinet 300.

[0092] Among them, the specific structure and technical effects of the flip cover structure have been elaborated and explained in detail in the previous text, so this application will not repeat them here.

[0093] It should be noted that the flip cover structure can be one or two. In the present embodiment, it is preferred that the flip cover structure is two, and the two flip cover structures are symmetrically distributed relative to the face cover 200. Figure 1 shown.

[0094] The above description is only an optional embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0095] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
