Description

Switch cabinet surface-mounted hinge and surface-mounted hinge switch cabinet

Technical Field

The utility model relates to a hinge is high with frame and door fixed strength, and door plant (panel) open and shut reliable and stable cubical switchboard obviously adorns hinge and obviously adorn hinge cubical switchboard belongs to the cubical switchboard field of making.

Background

The frame and the door plate (panel) of the switch cabinet are formed by sleeving a concealed hinge, the door plate (panel) and a concealed hinge FIG. 3 cold-rolled plate fixing piece are fixedly installed through a door plate installation screw hole of FIG. 3, and the other end of the concealed hinge is sleeved with a fixing pin rod welded on the frame through a sleeving hole of FIG. 4, so that the connection of the low-voltage cabinet frame and the door plate (panel) is completed. The method has the following defects: the concealed hinge is connected with the frame through the welding column and the bolt in a sleeved mode, and due to the fact that welding is easy to perform cold welding, welding strength is not high, a large door of the switch cabinet is heavy, and the situation that the door plate falls off easily occurs.

Disclosure of Invention

The design purpose is as follows: on the basis of the background technology, the switch cabinet surface-mounted hinge and the switch cabinet surface-mounted hinge are designed, wherein the hinge, the frame and the door are extremely high in fixing strength, and the door plate (panel) is stable and reliable to open and close.

The design scheme is as follows: in order to realize the design purpose of the utility model. The utility model discloses in structural design, designed a novel obviously adorn formula hinge, door plant fixed part in the obviously adorns the hinge adopts L type cast iron door plant stationary blade to at right angle portion design pivot supporting seat, and with the supporting seat as an organic whole erect the pivot. The advantages of such a design are: the L-shaped cast iron door plate fixing piece can greatly improve the bending strength of the L-shaped cast iron door plate fixing piece, has good deformation resistance, can not generate the phenomenon of unstable opening and closing of the door plate caused by self deformation after being fixed on the door plate of the switch cabinet, and ensures the stability of opening and closing of the door plate of the switch cabinet; secondly, the rotating shaft supporting seat is fixed at the right-angle part of the L-shaped cast iron door panel fixing piece, so that the right-angle surface of the supporting seat and the right-angle part of the L-shaped cast iron door panel fixing piece are integrated, the stability of the supporting seat is improved, and the strength of the L-shaped cast iron door panel fixing piece is enhanced; and thirdly, the L-shaped cast iron door frame fixing piece adopts a right-angled part, so that the strength of the L-shaped cast iron door frame fixing piece is improved, and the L-shaped cast iron door frame fixing piece is hinged with the L-shaped cast iron door plate fixing piece.

The technical scheme 1: a switch cabinet open-mounted hinge is characterized in that a rotating shaft supporting seat and an upright rotating shaft integrated with the supporting seat are arranged at the right angle part of an L-shaped cast iron door panel fixing piece, a rotating shaft sleeve is arranged at the end part of the L-shaped cast iron door frame fixing piece, and the rotating shaft sleeve on the L-shaped cast iron door panel fixing piece is sleeved on the upright rotating shaft to form the switch cabinet open-mounted hinge.

The technical scheme 2 is as follows: the utility model provides a bright dress hinge cubical switchboard, includes the cubical switchboard, L type cast iron door frame stationary blade upper ledge fixed screw hole and cubical switchboard frame riveting are fixed in the bright dress hinge, and L type cast iron door panel stationary blade fastens through a plurality of double-screw bolt mounting holes and cubical switchboard door plant in the bright dress hinge, and L type cast iron door frame stationary blade tip pivot cover that is located on cubical switchboard door panel constitutes bright dress hinge cubical switchboard in the pivot of erectting of L type cast iron door panel stationary blade.

Compared with the prior art, the utility model, obviously adorn the hinge and adopted draw-in groove location pivot for the accuracy is higher after each door plant (panel) installation, and each door plant (panel) overall arrangement of whole cubical switchboard is accurate, improves cubical switchboard protection level greatly, has solved the not part that the background art exists.

Detailed Description

Example 1: reference is made to figures 1 and 2. A switch cabinet open-mounted hinge is characterized in that a rotating shaft supporting seat 3 and an upright rotating shaft 5 integrated with the supporting seat are arranged at the right angle part of an L-shaped cast iron door frame fixing piece 1, a rotating shaft sleeve 6 is arranged at the end part of the L-shaped cast iron door frame fixing piece 4, and the rotating shaft sleeve 6 on the L-shaped cast iron door frame fixing piece 1 is sleeved on the upright rotating shaft 5 to form the switch cabinet open-mounted hinge. The door frame fixing part of the L-shaped cast iron door frame fixing piece 4 is of a special-shaped Z-shaped structure, and a plurality of frame fixing screw holes 7 are formed in a concave part of the special-shaped Z-shaped structure. The L-shaped cast iron door panel fixing sheet 1 is provided with a plurality of door panel fixing bolts 2.

Example 2: on the basis of embodiment 1, a surface-mounted hinge cubical switchboard, including cubical switchboard (not shown), frame fixed screw hole 7 and cubical switchboard frame riveting are fixed on L type cast iron door frame stationary blade 4 in the surface-mounted hinge, and L type cast iron door panel stationary blade 1 fastens with the cubical switchboard door plant through a plurality of double-screw bolt mounting holes in the surface-mounted hinge, and 4 tip pivot covers 6 covers of L type cast iron door frame stationary blade on the cubical switchboard door plant constitute surface-mounted hinge cubical switchboard on the pivot 5 of erectting of L type cast iron door panel stationary blade 1.

It is to be understood that: although above-mentioned embodiment is right the utility model discloses a design has done more detailed word description, but these word descriptions, are only right the utility model relates to a simple word description of idea, rather than right the utility model relates to a restriction of idea, any do not surpass the utility model relates to a combination, increase or the modification of idea all fall into the utility model discloses a within the protection scope.
