Abstract
The invention discloses a door support of a box body. The door support of the box body comprises a bracket, a supporting rod, a screw and a screw column, wherein the screw column is welded on the bracket; a hole is formed at one end of the supporting rod; the hole sleeved on the screw column; the screw and the screw column are fixed mutually; and the supporting rod is connected with the bracket. The door support of the box body has the advantages that: the structure is simple; the phenomenon of locking of the door support caused by that the supporting rod is directly fixed by a nut is eliminated; high-frequency door opening and closing and violent vibration can be withstood; the phenomena that the door support is loosened and falls apart are avoided; and safety and stability are greatly improved.
Description
Technical field
The present invention relates to a kind of casing portal bracing.
Background technology
The portal bracing of electrical equipment bin, power distribution cabinet is as shown in Figure 1, normally is made up of support 1, strut 2, screw 3, nut 4, and screw and nut combinations are fixed on strut on the support; This combining structure is simple; But during nut screwing clamping, strut will be stuck, and influences the mobility of switch door.But because door can not be too tight when switch; The two ends of portal bracing all will be in the state of easy activity; So nut fixing above the screw can not be tightened, so that door can make more and more pine of nut when often switch is with vibration; Cause whole portal bracing to fall apart, finally cause casing or even personal security to damage.
Summary of the invention
Goal of the invention: to the problems referred to above, the purpose of this invention is to provide a kind of casing portal bracing that can loose or dislocation.
Technical scheme: a kind of casing portal bracing, comprise support, strut, screw, also comprise double-screw bolt; Said stud welding is on said support, and said strut one end is offered the hole, and said borehole jack is on said double-screw bolt; Said screw and said double-screw bolt interfix, with said strut be connected at said support.
The diameter in said hole is greater than the diameter of said double-screw bolt, because screw and double-screw bolt are fixed, strut is limited on the double-screw bolt and rotates, and can not come off, so the aperture of offering on the strut can be greatly, so that strut rotates flexibly.
Beneficial effect: compared with prior art; Advantage of the present invention is simple in structure, has eliminated nut to the directly fixing portal bracing stuck phenomenon that is caused of strut, can stand high-frequency switch door and high vibration; The phenomenon that portal bracing also can not get loose even fall apart has improved security and stability greatly.

Fig. 2 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Like accompanying drawing 1, shown in 2, a kind of casing portal bracing comprises support 1, strut 2, screw 3, double-screw bolt 4, and double-screw bolt 4 is welded on the support 1, and strut 2 one ends are offered hole 5, and the diameter in hole 5 is greater than the diameter of double-screw bolt 4.Strut 2 is enclosed within on the double-screw bolt 4 through hole 5, and it is fixing that screw 3 and double-screw bolt 4 interconnect, with strut 2 be connected at support 1.Strut 2 can rotate on double-screw bolt 4, and simultaneously the nut of screw 3 stops and prevents that it from coming off out.
Claims (2)
1. casing portal bracing; Comprise support (1), strut (2), screw (3), it is characterized in that: also comprise double-screw bolt (4), said double-screw bolt (4) is welded on the said support (1); Said strut (2) one ends are offered hole (5); Said hole (5) is enclosed within on the said double-screw bolt (4), and said screw (3) and said double-screw bolt (4) interfix, with said strut (2) be connected at said support (1).
2. a kind of casing portal bracing according to claim 1 is characterized in that: the diameter of said hole (5) is greater than the diameter of said double-screw bolt (4).
