[0034] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The utility model provides an opening and closing structure, such as Figure 1 As shown, it includes a base 10 and an adjustment plate 20, wherein the adjustment plate 20 is provided with a long strip through hole 21, a stepped shaft 40 is passed through the through hole 21, a connecting piece 30 is connected between the base 10 and the stepped shaft 40, and the stepped shaft 40 can move in the through hole 21 to change the relative position between the base 10 and the adjustment plate 20.

[0038] The connection relationship between the connecting member 30 and the base 10 can change the relative movement mode between the base 10 and the adjustment plate 20 .

[0039] Specifically, when the connecting member 30 is fixedly connected to the base 10, the adjusting plate 20 can only translate relative to the base 10, and the direction of the translation is the same as the length direction of the through hole 21. At the same time, the stepped shaft 40 moves in the through hole 21. This can be used for some devices that are opened or closed by translation, such as sliding doors. The base 10 can be fixed to a wall or the ground, and the adjusting plate 20 can be fixed to the sliding door. At this time, the sliding door can be translated; similarly, when the connecting member 30 and the base 10 are rotationally connected, the connecting member 30 can rotate relative to the base 10. At the same time, the corresponding adjusting plate 20 can revolve relative to the base 10. At the same time, the stepped shaft 40 moves in the through hole 21 during the revolution. This can be used for some devices that are opened or closed by hinges or hinge connections, such as flip doors. Correspondingly, the distance that the stepped shaft 40 moves in the long strip through hole 21 will affect the flipping angle.

[0040] like Figure 2 and Figure 3 As described above, in order to ensure that the device can operate stably, in the present embodiment, a connected flare 22 is provided at the end of the through hole 21, and correspondingly, the stepped shaft 40 includes a movable portion 41 and a fixed portion 42. In the present embodiment, the fixed portion 42 is located above the movable portion 41, wherein when the stepped shaft 40 moves in the through hole 21, it is the movable portion 41 that moves in the through hole 21, and when the stepped shaft 40 moves to the position of the flare 22, the fixed portion 42 enters into the flare 22, and the flare 22 constrains the fixed portion 42, so that the stepped shaft 40 cannot move into the through hole 21 again, thereby making the stepped shaft 40 reach a locked state relative to the adjustment plate 20, and in order to enable the fixed portion 42 to smoothly enter the flare 22, a smooth transition portion 45 is provided between the movable portion 41 and the fixed portion 42.

[0041] Specifically, during use of the device, the movable portion 41 is first moved in the through hole 21. When it moves to the position of the flared opening 22, the movable portion 41 first contacts the flared opening 22. Under the action of gravity, the stepped shaft 40 moves downward, allowing the fixed portion 42 to enter the flared opening 22, achieving a locking effect, thereby achieving relative fixation between the base 10 and the adjustment plate 20. When unlocking is required, the stepped shaft 40 is moved upward to allow the movable portion 41 to contact the flared opening 22. At this time, the movable portion 41 can be moved in the through hole 21 again.

[0042] Specifically, Figure 5As shown, a mounting portion 43 cooperating with the connecting member 30 is provided on the stepped shaft 40, wherein the mounting portion 43 is penetrated on the connecting member 30, and a threaded hole 47 is provided on the end face of the mounting portion 43, in which a bolt 44 is cooperatingly installed to prevent the connecting member 30 and the mounting portion 43 from falling off, and a limiting plate 46 is installed on the stepped shaft 40, and the limiting plate 46 is used to prevent the stepped shaft 40 from passing through the flared opening 22. Specifically, in this embodiment, a limiting plate 46 is installed on the top of the fixed portion 42, and a mounting portion 43 is installed on the bottom of the movable portion 41.

[0043] like Figure 3 As shown, the cross-section of the movable part 41 is circular, and the diameter of the circular cross-section is equal to or smaller than the width of the through hole 21, so as to ensure that the movable part 41 can move stably in the through hole 21; at the same time, the cross-section of the movable part 41 is rectangular, and the long side of the rectangle is smaller than the width of the through hole 21, and the appropriate shape can be selected according to actual conditions.

[0044] First embodiment

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the cross-section of the fixing portion 42 is circular, and the corresponding flared opening 22 is also circular to match it, or the cross-sectional area of ​​the flared opening 22 is slightly larger than the cross-sectional area of ​​the fixing portion 42. At the same time, the circular diameter of the cross-section of the fixing portion 42 is larger than the width of the through hole 21.

[0046] During use of this embodiment, the cross-section of the movable portion 41 is selected to be circular, and the movable portion 41 moves in the through hole 21, at this time, the opening and closing structure can be opened or closed, and when the movable portion 41 moves to the position of the flared opening 22, at this time, under the action of gravity, the stepped shaft 40 moves downward, so that the fixed portion 42 enters the flared opening 22. At this time, since the width of the fixed portion 42 is greater than the width of the through hole 21, the fixed portion 42 cannot enter the through hole 21, and the stepped shaft 40 can only be at the position of the flared opening 22 to achieve a locking effect. When the stepped shaft 40 needs to be unlocked, it is only necessary to move the stepped shaft 40 upward so that the movable portion 41 contacts the flared opening 22, and the stepped shaft 40 can be moved into the through hole 21 to achieve an unlocking effect.

[0047] Correspondingly, when the opening and closing structure of the present embodiment is used for a sliding door of a translational type, the step shaft 40 can be selected to be in a closed state when it is in the flared position. At this time, the sliding door cannot be opened by itself, and the step shaft 40 needs to be additionally moved to open it. Vice versa, it can be selected according to actual conditions. When the opening and closing structure of the present embodiment is used for a flip door that is hinged, the step shaft 40 can be located in the flared position corresponding to the state of the door being opened. In this way, the door can be in a locked state when it is opened, and it can be conveniently used at this time.

[0048] Second embodiment

[0049] like Figure 8 and Fig. 9 As shown, in the present embodiment, the cross section of the fixing portion 42 is elliptical, so there is a short axis and a long axis in the cross section of the fixing portion 42, wherein the length of the short axis is greater than the width of the through hole 21, so that when the fixing portion 42 is located at the position of the flared opening 22, it can still play a locking effect. Correspondingly, when the stepped shaft 40 needs to be moved, it is also necessary to move the stepped shaft 40 upward so that the moving portion contacts the flared opening 22. Only then can the stepped shaft 40 be moved. At the same time, the diameter of the flared opening 22 is greater than the length of the long axis, so that when the stepped shaft 40 moves to the position of the flared opening 22, the fixing portion 42 can enter the flared opening 22 at any angle.

[0050] like Figure 6 and Figure 7 As shown, in order to enable the stepped shaft 40 to be locked at other positions on the through hole 21 except the flared opening 22, a plurality of first locking openings 23 are provided on the through hole 21 along its length direction, wherein the cross-sectional shape of the first locking openings 23 is elliptical, which is adapted to the cross-sectional shape of the fixing portion 42, so that when the movable portion 42 on the stepped shaft 43 moves to the position of any first locking opening 23, by rotating the stepped shaft 43 so that the offset angle of the fixing portion 42 is the same as the angle of the corresponding first locking opening 23, the fixing portion 42 can fall into the first locking opening 23 at this time, thereby achieving a locking effect.

[0051] Specifically, Figure 7 As shown, when the stepped shaft 40 moves on the through hole 21, the moving portion 41 is in contact with the through hole 21. When the stepped shaft 40 moves to the position of one of the first locking openings 23, the stepped shaft 40 is rotated to rotate around the axis, and the corresponding angle of the fixed portion 42 will also change, so that the angle of the fixed portion 42 is consistent with the angle of the first locking opening 23. At this time, under the action of gravity, the stepped shaft 40 moves downward, so that the fixed portion 42 falls into the first locking opening 23, thereby achieving a locking effect. Since there are multiple first locking openings 23, the stepped shaft 40 can have multiple positions for locking, which can adapt to different situations.

[0052] Specifically, when the adjustment plate 40 moves through translation, the corresponding sliding door can achieve different degrees of opening and closing, such as opening half or one third, etc., which is determined according to the position and number of the first locking holes 23. For the flip door realized by hinges or hinges, the first locking hole 23 can be opened to different angles, such as 60° or 90°, etc., which is also determined according to the position and number of the first locking holes 23, and has a wider range of adaptability.

[0053] like Figure 7 As shown, in order to make it more convenient to use, the user can directly make the stepped shaft 40 fall into the designated first locking hole 23 during use, wherein the angles of the first locking holes 23 are different. Only when the angle of the fixing portion 42 is consistent with the angle of the first locking hole 23, the fixing portion 42 can fall into the first locking hole 23. Therefore, during use, the fixing portion 42 can be rotated to the designated angle first. At this time, when the stepped shaft 40 moves in the through hole 21, it is not affected by other first locking holes 23 and can move smoothly until it reaches the position of the designated first locking hole 23, which is more convenient to use.

[0054] Third embodiment

[0055] like Fig.12 and Fig.13 As shown, in the present embodiment, the cross-section of the fixing portion 42 is circular, and a locking block 48 is provided on the side of the fixing portion 42, so that the cross-section of the fixing portion 42 is a protruding circle, and the corresponding through hole 21 is provided with a plurality of second locking holes 24 adapted to the cross-sectional shape of the fixing portion 42, wherein the angles of the second locking holes 24 are different, so that the user only needs to rotate the stepped shaft 40 to a preset angle during use, and in the process of opening the opening and closing structure, the stepped shaft 40 will automatically fall into the designated second locking hole 24, so that it can be locked at different positions or angles, which is more convenient and reliable to use.

[0056] At the same time, in this embodiment, the extended length of the locking block 48 plus the cross-sectional diameter of the fixing portion 42 is smaller than the diameter of the flared opening 22, so that when the stepped shaft 40 moves to the position of the flared opening 22, the fixing portion 42 can enter the flared opening at any angle to achieve locking.

[0057] Further, such as Figure 8 and Fig.12 As shown, in order to allow the fixed part 42 on the stepped shaft 40 to fall better, a rectangular counterweight block 47 is provided on the limiting plate 46, wherein the counterweight block 47 enables the stepped shaft 40 to move more stably in the through hole 21, and at the same time, it is convenient for the user to rotate the counterweight 47 with two fingers, and it is also convenient to adjust the angle of the stepped shaft 40, which is convenient for the user to use.

[0058] The present invention also provides a ring main unit, such as Fig.14 and Fig.15As shown, the ring main unit includes a cabinet body 50 with an opening on one side, a cabinet door 51 is rotatably installed at the opening of the cabinet body 50, and an opening and closing structure 60 as described above is installed between the cabinet body 51 and the cabinet door 51. Specifically, the cabinet body 50 is installed with a base 10 as described above, and the cabinet door 51 is installed with an adjustment plate 20 as described above. Through the opening and closing structure 60, the preset angle of the cabinet door 51 can be fixed, so as to facilitate the staff to work at the opening of the cabinet body 50.

[0059] In order to facilitate the installation of communication equipment inside the ring network cabinet, vertical beams 52 are symmetrically installed inside the cabinet 50, wherein the vertical beams 52 are provided with modular holes, wherein a horizontal beam 53 is installed between the two vertical beams 52 through the modular holes, and the horizontal beam 53 is provided with modular holes, and the communication equipment can be installed on the horizontal beam 53, and the position of the horizontal beam 53 can also be conveniently adjusted through the modular holes, which is convenient for users to use. In order to facilitate the installation of communication equipment, the communication equipment is connected with an aviation plug, and a dehumidifier can also be provided in the cabinet 50 to ensure that the cabinet 50 remains dry.
