Description

Case cover connecting structure of control case

Technical Field

The utility model relates to a technical field of control box, more specifically say, it relates to case lid connection structure of control box.

Background

The PLC control cabinet has the protection functions of overload, short circuit, open-phase protection and the like. It has compact structure, stable operation and complete functions. The intelligent control system can be combined according to the size of an actual control specification, not only can realize single-cabinet automatic control, but also can realize that a plurality of cabinets form a Distributed Control System (DCS) through an industrial Ethernet or an industrial field bus network.

The small PLC control box is internally provided with starting electrical elements, the electrical elements are firstly arranged with a panel in a fixed mounting mode and a flat cable mode, then the panel is fixed in the control box through a plurality of screw rods, finally the box cover and the control box are fixed to realize sealing, and the assembly and disassembly efficiency of the installation mode is very low.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a rational in infrastructure simple, the practicality is strong, makes things convenient for the case lid connection structure of the control box of dismouting.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the box cover connecting structure of the control box comprises a control box and a box cover for sealing the cover, a panel for arranging cables and electric elements is arranged in the control box, the connecting structure comprises a positioning part and a locking part,

the positioning parts are movably connected with the control box and are provided with four parts which are respectively arranged on four corners of the control box, a through hole is penetrated through the center of the positioning parts,

the locking part comprises a rod piece which is arranged on the box cover and corresponds to the positioning part and a sleeve piece which is arranged on the panel;

the end part of the rod piece is provided with screw threads, the sleeve piece is of a hollow structure, the inner wall of the sleeve piece is provided with internal screw threads,

the positioning part moves relative to the control box and compresses the panel, the panel is synchronous, the sleeve piece stretches into the panel from one end of the through hole, and the rod piece stretches into the panel from the other end of the through hole and is in threaded connection with the sleeve piece.

The utility model discloses further set up to: the control box edge has the sand grip, and the outer wall of location portion has the spout with the sand grip adaptation.

The utility model discloses further set up to: and a rubber pad is arranged on the end face where the positioning part and the panel are abutted.

The utility model discloses further set up to: the positioning part is fan-shaped.

Contrast prior art not enough, the beneficial effects of the utility model are that:

when the installation, will be equipped with winding displacement and electric elements's panel and place the control box in, then insert location portion at four corners of control box for location portion extrudees four corners of panel, and after location portion and panel supported, directly covers the case lid, then locking portion and location portion connect, accomplish the installation. The whole process is obviously improved compared with the traditional assembling and disassembling efficiency.

Fig. 1 is a schematic sectional view of the present invention.

Fig. 2 is a schematic top view of the control box.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 2.

The embodiment has the structure: the control box comprises a control box 1 and a box cover 2 used for sealing the cover, a panel 3 for arranging cables and electric elements is arranged in the control box 1, and the connecting structure comprises a positioning part 4 and a locking part.

The positioning part 4: the four positioning parts are movably connected with the control box 1, are respectively arranged on four corners of the control box 1, and are provided with through holes 40 in the center thereof, and the positioning parts 4 are in fan shapes.

Both sides wall of 1 corner of control box all has sand grip 11, and the outer wall of location portion 4 has the spout with the 11 adaptations of sand grip.

Locking part: comprises a rod piece 6 which is arranged on the box cover 2 and corresponds to the positioning part 4 and a sleeve piece 5 which is arranged on the panel 3.

The end of the rod piece 6 is provided with screw threads, the sleeve piece 5 is of a hollow structure, the inner wall of the sleeve piece 5 is provided with internal screw threads,

the relationship of the assembled components is as follows:

place panel 3 in control box 1, then insert the spout on location portion 4 towards the sand grip 11 of control box 1, location portion 4 compresses tightly panel 3 along sand grip 11, in the in-process that location portion 4 and panel 3 contradict, the external member 5 on the panel 3 can insert it from the lower extreme of the through-hole 40 at location portion 4 center, the position of placing panel 3 and location portion 4 sends the skew, after four location portions 4 all supported with panel 3, directly cover case lid 2 on control box 1, then insert and stretch into and external member 5 threaded connection from location portion 4 center through-hole 40 upper end through member 6, the completion assembly. In the above structure, the aperture of the port of the through hole 40 of the positioning portion 4, into which the sleeve 5 extends, is larger than the diameter of the central portion thereof, so as to form a cavity for accommodating the sleeve 5, the diameter of the cavity is larger than the diameter of the portion of the rod 6 extending into the cavity, the structure improves the connection stability of the rod 6 and the sleeve 5, and the rod 6 has external threads only at the end of the portion in threaded connection with the sleeve 5, and the rest of the rod is a smooth curved surface, so that the rod can be conveniently inserted into the positioning portion 4. In order to reduce the rigid external force generated by the interference between the positioning part 4 and the panel 3, a rubber pad 7 is disposed on the end face where the positioning part 4 and the panel 3 interfere.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
