Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment frameworks and relates to a novel connection structure for frameworks. Background Art

[0002] The main framework of an electrical cabinet is usually in the form of a combination of vertical columns and cross beams, which is used to bear all the loads of the electrical cabinet. The common framework combination installation method is to fix the vertical column and the cross beam through several bolts.

[0003] In the existing combination installation method, multiple components are also required to cooperate with the bolts for fixation, including flat washers, spring washers, nuts, reinforcing plates, etc., to ensure the fixation performance of a single set of bolts. However, in order to ensure the strength of each part in a framework, dozens of sets of bolts are often required. The installation operation of a single set of bolts is already somewhat cumbersome, and dozens of sets bring a huge workload, resulting in extremely cumbersome installation operations for users and difficult to improve the installation efficiency.

[0007] Further, it further includes a positioning sleeve. The positioning sleeve is in a hollow cylindrical structure. One end of the positioning sleeve abuts against the inner side of the counterbore, and the positioning sleeve is coaxial with the counterbore.

[0008] Further, screw holes for threaded connection of the self-tapping installation screws are formed on the reinforcing plate.

[0009] Further, a connecting piece for fitting with the side wall of the cross beam or the side wall of the vertical column is bent and arranged on the outer periphery of the reinforcing plate, and mounting holes are formed on the connecting piece.

It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0020] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components during actual implementation. The types, quantities, and ratios of the components during actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0021] In the embodiments of the present utility model, all directional indications (such as up, down, left, right, front, back, horizontal, vertical...) are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0022] Due to reasons such as installation errors, the parallel relationship referred to in the embodiments of the present utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0023] A new type of frame connection structure is mainly used for the quick connection between the vertical column and the cross beam 1 at the vertex position of the frame.

[0024] Refer to Figure 1 As shown, the frame includes a straight upper vertical column 21, a side lower vertical column 22 and a cross beam 1. The straight upper vertical column 21 is arranged along the vertical direction. The side lower vertical column 22 is horizontally arranged on one side of the bottom of the straight upper vertical column 21. One end of the side lower vertical column 22 is opposite to one side surface of the straight upper vertical column 21. The cross beam 1 is horizontally arranged on the other side of the bottom of the straight upper vertical column 21. One end of the cross beam 1 is opposite to the other side surface of the straight upper vertical column 21. In this embodiment, the cross beam 1 and the side lower vertical column 22 are perpendicular.

[0025] The connection structure includes a reinforcing plate 3. In this embodiment, the reinforcing plate 3 is arranged at one end of the cross beam 1. When the reinforcing plate 3 is connected with the cross beam 1 in a matching manner, the reinforcing plate 3 forms the end face of the cross beam 1 at this end for facing the side surface of the straight upper vertical column 21 and the side surface of the side lower vertical column 22. The edge of the reinforcing plate 3 is bent to form a plurality of connecting pieces 31. When the reinforcing plate 3 is connected with the cross beam 1 in a matching manner, the connecting pieces 31 are attached to the outer side wall or the inner side wall of the cross beam 1. Installation holes for passing bolts are formed on the side walls of the connecting pieces 31 and the cross beam 1, so that the reinforcing plate 3 and the cross beam 1 are fixedly connected through bolts.

[0026] Refer to Figure 3 , at least two screw holes 32 are formed on the reinforcing plate 3. When the cross beam 1 and the reinforcing plate 3 are respectively abutted against the straight upper vertical column 21 and the side lower vertical column 22, the two screw holes 32 are respectively opposite to the straight upper vertical column 21 and the side lower vertical column 22. Through holes are formed on the side walls of the straight upper vertical column 21 and the side lower vertical column 22. The connection structure further includes two self-tapping installation screws 5. The two self-tapping installation screws 5 respectively pass through the two through holes and are respectively threadedly connected with the two screw holes 32. Tighten the self-tapping installation screws 5 so that their nuts abut against the inner wall of the straight upper vertical column 21 or the inner wall of the side lower vertical column 22, and the fixed connection among the cross beam 1, the straight upper vertical column 21 and the side lower vertical column 22 can be realized.

[0027] In order to ensure the support stability during the installation of the self-tapping installation screws 5 and improve the strength of the installation connection, refer to Figure 4, in this embodiment, counterbores 23 are provided on both the vertical upper column 21 and the lateral lower column 22, which are respectively referred to as the first counterbore 23 and the second counterbore 23. The counterbore 23 is formed on the outer wall of the vertical upper column 21 or the lateral lower column 22 and is recessed downward toward the inside of the column. The bottom of the counterbore 23 is provided with a through hole for the self-tapping screw 5 to pass through. When the cross beam 1 and the reinforcing plate 3 are respectively in contact with the vertical upper column 21 and the lateral lower column 22, the directions in which the two counterbores 23 penetrate are respectively opposite to the two screw holes 32, that is, the two counterbores 23 are coaxially arranged with the two screw holes 32. During installation, the self-tapping screw 5 first passes through the counterbore 23, and the counterbore 23 guides the screw, so that the self-tapping screw 5 can be accurately installed into the screw hole 32 subsequently.

[0028] The recessed area of the counterbore 23 can be set to include but not limited to shapes such as conical and cylindrical that are adapted to the nut of the self-tapping screw 5, so that when the self-tapping screw 5 is installed in place in the screw hole 32, its nut is just located in the counterbore 23 and is clamped and matched with the inner wall of the counterbore 23. Thus, the double-point positioning and orientation of the self-tapping screw 5 are achieved through the screw hole 32 and the counterbore 23, effectively ensuring the support stability of the connection and thus guaranteeing the installation strength.

[0029] Furthermore, referring to Figure 2 , it further includes a positioning sleeve 4. The positioning sleeve 4 has a hollow cylindrical structure and includes two open ends in the axial direction. The positioning sleeve 4 is used to provide strength support for the counterbore 23. There are two positioning sleeves 4, which are respectively located inside the vertical upper column 21 and the lateral lower column 22. One of the open ends of the two open ends in the axial direction of the positioning sleeve 4 abuts against the inner side wall of the vertical upper column 21 or the lateral lower column 22 and is communicated with the through hole, and the other open end abuts against the inner side of the counterbore 23 and is arranged around the circumference of the counterbore 23 and is communicated with the counterbore 23. Thus, when the self-tapping screw 5 is installed, it passes through the positioning sleeve 4 along the axial direction, and the support of the positioning sleeve 4 for the counterbore 23 effectively avoids the deformation that the counterbore 23 may occur when the self-tapping screw 5 is tightened.

[0030] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
