Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, specifically relating to a rotatable PDU sheet metal hanging lug structure. Background Technology

[0002] PDU sockets are widely used for powering server rooms and office cluster equipment. Most existing PDU socket installation methods use sheet metal mounting ears on both sides, secured to the server rack or desk with screws and nuts. Because the fixed sheet metal mounting ear structure directly connects the ears to the PDU socket body with screws, it has the advantages of simple structure and low cost, making it widely used. However, this installation method has the following drawbacks:

[0003] 1. The fixed design of the PDU socket has only one installation direction, supporting only horizontal or vertical installation, which cannot adapt to the layout needs of different cabinets and office scenarios.

[0004] 2. Currently, the mounting methods for PDU sockets, including the mounting lugs and the main body, are mostly screw-mounted. Both installation and removal require specific tools, which reduces the efficiency of installation and disassembly. Utility Model Content

[0005] In view of the above-mentioned problems mentioned in the background art, this utility model provides a rotatable PDU sheet metal hanging ear structure to solve the problems of the fixed design of PDU socket hanging ears having a single direction and the screw installation reducing the efficiency of PDU socket hanging ear installation and disassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rotatable PDU sheet metal mounting lug structure, comprising:

[0008] PDU socket; the first side of the PDU socket is provided with studs;

[0009] Gasket; The gasket has a first through hole and a circular post on the front side of the gasket. The center of the first through hole is located on the central axis of the circular post. The gasket is fitted onto the stud through the circular post and the first through hole. The top of the circular post is pressed into contact with the first side of the PDU socket.

[0010] Nut; the nut is threaded to the stud, and the nut is pressed against the back of the washer.

[0011] At least two elastic clips; the elastic clips are fixedly installed on the front of the gasket, and all the elastic clips are arranged in a ring along the central axis of the annular column. Each elastic clip has an arc-shaped protrusion on the side facing away from the annular column.

[0012] Sheet metal hanging ear; the sheet metal hanging ear is an L-shaped plate including a first plate and a second plate. The first plate has at least one strip hole, and the second plate has a second through hole. The cross-section of the second through hole is a regular polygon, and each vertex of the regular polygon is set with the same arc segment. The edge of the regular polygon is composed of multiple straight segments and multiple arc segments connected alternately. The arc segment on the cross-section of the second through hole is manifested as an arc-shaped through groove that cooperates with the arc-shaped protrusion. The second plate is fitted onto all the elastic buckles through the second through hole. In the initial state, an arc-shaped protrusion is inserted into an arc-shaped through groove. When the external force drives the second plate to rotate, each arc-shaped protrusion slides out of the arc-shaped through groove under the action of the deformation of the elastic buckle and presses against the side wall of the second through hole.

[0013] Preferably, the elastic buckle is an arc-shaped part, with the side of the elastic buckle facing the circular column being an inner arc surface, and an arc-shaped protrusion being set at the center of the outer arc surface of the elastic buckle.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] like Figure 1 , Figure 2 As shown, a rotatable PDU sheet metal hook structure includes:

[0032] PDU socket; The PDU socket includes a socket base plate 2 and a socket panel 1. The top of the first side of the socket base plate 2 is provided with a semi-threaded post, and the bottom of the first side of the socket panel 1 is provided with a semi-threaded post. The socket panel 1 and the socket base plate 2 are fixedly connected to form a PDU socket. The threaded post of the socket base plate 2 and the semi-threaded post of the socket panel 1 cooperate with each other to form a complete stud 6. The thread of the stud 6 is an M16 thread. When the PDU socket is subjected to vibration and collision under the influence of external force, this structure can use the nut 5 to further fix the socket base plate 2 and the socket panel 1 of the PDU socket to prevent them from separating.

[0033] Gasket 7; Gasket 7 is a circular part with a first through hole. A circular ring post 9 is provided on the front side of gasket 7. The center of the first through hole is located on the central axis of the circular ring post 9. Gasket 7 is fitted onto stud 6 through the circular ring post 9 and the first through hole. The top of the circular ring post 9 is in contact with the first side of the PDU socket.

[0034] Nut 5; Nut 5 is threaded to stud 6, and nut 5 is pressed against the back of washer 7. Nut 5 is an M16 flange nut.

[0035] Three elastic buckles 10 are fixedly installed on the front of the gasket 7. All elastic buckles 10 are arranged in a ring along the central axis of the annular column 9. The elastic buckles 10 are arc-shaped. The side of the elastic buckle facing the annular column 9 is an inner arc surface. An arc-shaped protrusion is provided at the center of the outer arc surface of the elastic buckle 10. The angle between the line connecting two adjacent arc-shaped protrusions and the central axis of the annular column 9 is 120°. The bottom surfaces of both ends of the elastic buckle 10 are fixedly connected to the front of the gasket 7. The part of the gasket 7 located below the middle section of the elastic buckle 10 is hollow. The hollow design can improve the elasticity of the elastic buckle 10. Both the gasket 7 and the elastic buckle 10 are made of plastic.

[0036] Sheet metal mounting ears; the sheet metal mounting ears are L-shaped plates including a first plate 4 and a second plate 3. The first plate 4 has three strip holes, and the second plate 3 has a second through hole. The cross-section of the second through hole is a regular dodecagon, and each vertex of the regular dodecagon is set with the same minor arc segment. The edge of the regular dodecagon is composed of multiple straight segments and multiple minor arc segments connected alternately. The minor arc segment on the cross-section of the second through hole is manifested as an arc-shaped through groove that matches the arc-shaped protrusion. The minor arc can provide a locking position for the arc-shaped protrusion while providing a channel for rotation. If a major arc is used, the arc-shaped protrusion may be stuck and unable to be rotated out. The second plate 3 is fitted onto all the elastic buckles 10 through the second through hole. The second plate 3 is rotatably set between the PDU socket and the gasket 7, and the gasket 7 can completely cover the second through hole. Figure 3 , Figure 4 As shown, in the initial state, an arc-shaped protrusion is inserted into an arc-shaped through groove. When the external force drives the second plate 3 to rotate, the side wall of the arc-shaped through groove squeezes the arc-shaped protrusion. At the same time, the elastic buckle 10 is deformed in the direction of the annular column 9 under pressure. After the deformation reaches a certain degree, each arc-shaped protrusion slides out of the arc-shaped through groove and squeezes into contact with the side wall of the second through hole. The rotation continues until it rotates to the next arc-shaped through groove. When the pressure on the elastic buckle 10 disappears, it pops out and locks. The minimum rotation angle of this application is 30°, which can achieve 360° rotation.

[0037] Two limiting strips 8; one limiting strip 8 is simultaneously fixedly connected to the inner side wall of the annular post 9 and the inner side wall of the first through hole. The side of the stud 6 is provided with two limiting through grooves that are adapted to the limiting strips 8. When the gasket 7 is installed from the top of the stud 6 toward the PDU socket, the end of one limiting strip 8 enters from one end of one limiting through groove. After the gasket 7 is installed, one side of one limiting strip 8 is set in one limiting through groove.

[0038] In this embodiment, the elastic buckle 10 of this application can cooperate with the specially designed second through hole on the sheet metal hanging ear to realize the rotation angle controllable rotation adjustment function, which solves the problem that the fixed sheet metal hanging ear of the PDU socket has a single installation direction and cannot adapt to different layout requirements. It realizes multi-directional installation adjustment and greatly improves flexibility. This application uses nuts 5 and studs 6 for assembly and clamping. No other tools are needed. Tightening and loosening can be completed manually, which improves the efficiency of installation and disassembly. Moreover, the technical solution described in this application can be implemented on both sides of the PDU socket, that is, the hanging ear structure is installed on both ends of the PDU socket. The two hanging ear structures can be adjusted independently to suit more scenarios.
