Description

Technical Field

[0001] The utility model relates to a switch cabinet and belongs to the technical field of power equipment. Background Art

[0002] Ordinary switch cabinets often use hinges to connect the cabinet body and the cabinet door so that the cabinet door can be opened or closed. Existing hinges can only open the cabinet door in a horizontal motion. Since the cabinet door is made of sheet metal and the direction of the force applied by the user to open or close the door is not completely consistent when using it, it is equivalent to applying complex forces to the hinge when the cabinet door is opened repeatedly, which causes the hinge to be damaged or fail, making the cabinet door unable to be opened.

[0040] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0041] The names of the messages or information exchanged between multiple devices in the implementation manner of the present invention are only used for illustrative purposes, and are not used to limit the scope of these messages or information.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] Reference Figures 1 to 6 As shown, the switch cabinet 100 of the present invention includes: a cabinet body 101 , a cabinet door 102 , a first fixing block 103 , a second fixing block 104 , and a locking nut 105 .

[0044] The cabinet body 101 is formed with an inner cabinet space for accommodating electric equipment; the cabinet door 102 is at least rotatably connected to the cabinet body 101 so that the cabinet door 102 has an open state for opening the inner cabinet space and a closed state for closing the inner cabinet space relative to the cabinet body 101. The cabinet body 101 of the utility model can be made of a frame and sheet metal. The cabinet door 102 of the utility model can be made of sheet metal bent.

[0045] The first fixing block 103 and the second fixing block 104 are used to form a hinge mechanism between the cabinet body 101 and the cabinet door 102 .

[0046] Specifically, the first fixing block 103 is fixedly connected to the cabinet 101; the second fixing block 104 is fixedly connected to the cabinet. The first fixing block 103 and the cabinet 101 can be fixedly connected by welding or fasteners, and of course, can be connected by snap-fit ​​or interference fit. The second fixing block 104 and the cabinet door 102 can also be connected by a similar solution.

[0047] Reference Figures 1 to 6 As shown, the first fixing block 103 includes a first body 1031. Specifically, the first body 1031 is formed with a rotating shaft hole 1031a and a guide groove 1031b.

[0048] Reference Figure 6 As shown, as a more specific solution, the shaft hole 1031a at least includes a rotating body wall formed around the rotation axis; the guide groove 1031b is at least arranged at the hole wall of the shaft hole 1031a and extends in a direction obliquely intersecting with the rotation axis.

[0049] Reference Figures 1 to 6 As shown, the second fixing block 104 includes: a second body 1041 , a steering shaft 1042 and a threaded column 1043 .

[0050] Specifically, the second body 1041 is directly fixedly connected to the cabinet body 101; the steering shaft body 1042 is rotatably arranged in the shaft hole 1031a; the steering shaft body 1042 is formed or connected with a guide protrusion 1042a, and the guide protrusion 1042a is embedded in the guide groove 1031b to enable the cabinet door 102 to slide relative to the cabinet body 101 when it is rotated to open or close relative to the cabinet body 101.

[0051] By adopting the above scheme, when the cabinet door 102 is opened or closed relative to the cabinet body 101, even if the direction of the force applied to the cabinet door 102 by the user is complex (not completely horizontal), or the force applied to the hinge is complex due to the characteristics of the sheet metal of the cabinet door 102 (transmitting deformation), the force can be released by the relative rotation of the first fixed block 103 and the second fixed cabinet, thereby increasing the practical life of the hinge.

[0052] Specifically, in some embodiments, the shaft hole 1031a is configured to have a cylindrical wall surface.

[0053] Specifically, in some embodiments, the guide groove 1031b is configured as a spiral groove surrounding the wall of the cylinder.

[0054] Adopting such a solution can help the customer overcome the gravity of the cabinet door 102 to a certain extent when opening the door.

[0055] Reference Figure 4 and Figure 5 As shown, specifically, in some embodiments, the first body 1031 is further formed with a stepped groove 1031c, which is disposed at the top of the shaft hole 1031a and forms a stepped structure with the shaft hole 1031a.

[0056] This facilitates the assembly of the steering shaft 1042. As a preferred solution, a mounting notch 1031d communicating with the guide groove 1031b is provided at the step structure, so as to facilitate the guide protrusion 1042a to enter the guide groove 1031b.

[0057] Reference Figure 3 and Figure 6 As shown, specifically, in some embodiments, the steering shaft body 1042 is constructed as a cylinder with the rotation axis as the axis, and the guide protrusion 1042a is constructed as a truncated cone with one radial direction of the cylinder as the central axis.

[0058] Such a shape can realize both rotation limitation and lifting limitation.

[0059] Reference Figure 2 , Figure 3 and Figure 6As shown, specifically, in some embodiments, the threaded column 1043 is formed with an external thread; the locking nut 105 is formed with an internal thread that can cooperate with the external thread; wherein the threaded column 1043 is arranged at the end of the steering shaft body 1042; the steering shaft body 1042 is arranged between the second body 1041 and the threaded column 1043; the locking nut 105 is sleeved on the outside of the threaded column 1043; the steering shaft body 1042 passes through the shaft hole 1031a so that the threaded column 1043 extends out of the outside of the first body 1031; the first body 1031 is arranged between the second body 1041 and the locking nut 105. In this way, the installation and positioning between the components can be achieved.

[0060] Specifically, in some embodiments, the length of the steering shaft body 1042 is greater than the length of the shaft hole 1031a. The length difference between the steering shaft body 1042 and the shaft hole 1031a is greater than the dimension of the guide groove 1031b in the direction of the rotation axis.

[0061] This will provide enough room for rotation.

[0062] Specifically, in some embodiments, a plurality of groups of first fixing blocks 103 and second fixing blocks 104 are arranged between the cabinet body 101 and the cabinet door 102 .

[0063] This ensures the support for rotation and the limiting effect of the rotation guide.

[0064] The above description is only some preferred embodiments of the utility model and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the utility model is not limited to the technical solutions formed by the specific combination of the above technical features, but also should cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above invention concept. For example, the above features are replaced with the technical features with similar functions disclosed in the embodiments of the utility model (but not limited to) to form a technical solution.
