[ detailed description ] embodiments
In order to make the objects, technical solutions and advantageous technical effects of the present invention more clearly understood, the present invention is further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration only and not by way of limitation.
The utility model provides an anti-rotation structure insulated column 100 for be connected fixedly with the fixed plate, play fixed plate and circuit device fixed stay, be connected and insulating effect. Among these, circuit devices include, but are not limited to: power lines, copper plates or other electronic components needing insulation and fixation.
As shown in fig. 1 and 2, the anti-rotation structure insulating column 100 includes an insulating column 10 in a cylindrical shape, the insulating column 10 is mainly made of an insulating material, such as an insulating rubber, and mainly provides a supporting and separating effect for the devices fixedly connected to the two ends of the insulating column 10, so as to prevent the devices at the two ends from touching and causing a short circuit, and simultaneously prevent the devices at the two ends from forming an electrical loop through the insulating column 10, thereby damaging the devices. In this embodiment, the insulating cylinder 10 has a cylindrical shape. Further, for convenience of processing and fixing during installation, the cross section of the insulating column 10 may be a regular polygon, in this embodiment, a regular hexagon.
One end of the insulating cylinder 10 is provided with a screw hole 20, the screw hole 20 is a cylindrical groove structure, and the inner wall is provided with threads for matching and fixing with a bolt (not shown in the figure) of a device. The end of the insulating cylinder 10 far away from the screw hole 20 is fixed with a cylindrical anti-rotation step 30, the cross section area of the anti-rotation step 30 is smaller than that of the insulating cylinder 10, and the part of the insulating cylinder 10 which is not connected with the anti-rotation step 30 plays a role in limiting the open hole of the fixing plate 200. The cross section of the anti-rotation step 30 is an equilateral triangle or a square, and is used for being clamped and fixed with the opening of the fixing plate 200, so that relative rotation between the anti-rotation step 30 and the fixing plate 200 is avoided. When the rotation preventing step 30 is engaged with an opening of a fixing plate 200, the insulating cylinder 10 cannot be rotated in the fixing plate 200, thereby preventing rotation. The end of the anti-rotation step 30 away from the insulation column 10 is provided with a stud 40, and the stud 40 is used for matching with a nut 210 to fix the fixing plate 200 on the stud 40.
In a specific operation, as shown in fig. 4, the insulating cylinder 10 is first screwed to a device (e.g., a metal plate) (not shown) through the screw hole 20, so that one end of the insulating cylinder 10 is fixed. Then, the opening of the other fixing plate 200 is engaged with the rotation preventing step 30, and the other end of the insulating column 10 is fixed to the fixing plate 200 by the engagement of the nut 210 and the stud 40. In the process of fastening the nut 210 and the bolt 40, since the rotation preventing step 30 prevents the relative rotation with the fixing plate 200, the situation that one end of the screw hole 20 driving the insulating cylinder 10 is rotated and unscrewed when fastening is performed is avoided. Other tools are not needed to fix the insulating column 10, so that the operation process is simplified, the operation efficiency is improved, and the automation degree is improved.
Further, in one embodiment, as shown in fig. 1 and 3, the outer wall of the insulation cylinder 10 near the end of the anti-rotation step 30 protrudes laterally away from the insulation cylinder 10 to form a clamping member 50, and the cross section of the clamping member 50 is regular hexagon. Specifically, one end of the insulation cylinder 10 near the anti-rotation step 30 protrudes outward to form a regular hexagonal clamping member 50, or a cylindrical clamping member 50 is disposed between the insulation cylinder 10 and the anti-rotation step 30. When the end of the insulative cylinder 10 adjacent to the threaded hole 20 is fastened to the bolt, a wrench or the like is used to grip the clamp 50 and rotate the insulative cylinder 10, thereby completing the fastening.
Further, in one embodiment, as shown in fig. 3, the side wall of the anti-rotation step 30 is provided with a plurality of fastening protrusions 31. The clamping protrusions 31 may be hemispherical protrusions or strip-shaped protrusions uniformly distributed around the side wall of the anti-rotation step 30. When the anti-rotation step 30 is fixed on the opening of the fixing plate 200, the clamping protrusion 31 can increase the clamping strength of the two to prevent slipping.
Further, in one embodiment, the central axes of the insulating cylinder 10, the screw hole 20, the anti-rotation step 30 and the stud 40 are located on the same straight line, and at this time, the pressures applied to the two ends of the insulating cylinder 10 are exactly on the central axis of the insulating cylinder 10, and the pressures applied to the two ends are mutually offset, so that the insulating cylinder 10 will not be inclined due to unbalanced forces applied to the two ends when the insulating cylinder 10 is fixed, and the supporting and insulating functions of the anti-rotation structure insulating cylinder 100 will not be affected.
To sum up, the utility model discloses a set up between insulating cylinder 10 and double-screw bolt 40 and prevent changeing step 30, will be close to screw 20 one end earlier and fix on a fixed plate, during the other end installation, will prevent changeing step 30 and fix in the trompil of another fixed plate, need not reuse spanner or other instrument and fix insulating cylinder 10, simplified the installation, promoted operating efficiency.
