Detailed Description

The following is further detailed by the specific embodiments:

the reference numerals in the drawings of the specification include a display panel 1, a column 2, a base 3, a bolt 4, a steel ball 5, a ball 6, and a magnet 7.

Example 1

The embodiment of the signboard reinforcing mechanism of the utility model is basically as shown in the attached figure 1, and comprises a display panel 1, a column 2, a base 3, a bolt 4, a steel ball 5 and a ball 6. The lower frame of the display panel 1 is processed with a threaded hole, the upper end of the upright post 2 is processed with a thread matched with the threaded hole, and the upright post 2 is rotated to enable the thread to enter the threaded hole of the display panel 1. The upright post 2 is cylindrical, a first annular groove is processed at the lower end of the upright post 2,

base 3 is cylindrical, is made by cement material, and base 3 processing has the spout, and the spout is cylindrical, and stand 2 is placed in the spout, and the processing of spout inside wall face has second annular groove. The cross sections of the first annular groove and the second annular groove are square, engine oil is coated in the first annular groove and the second annular groove, and steel balls 5 are placed in the second annular groove; the width of the first annular groove is the same as the diameter of the screw hole, the central line of the first annular groove and the axis of the screw hole are positioned on the same straight line, and the bolt 4 penetrates through the screw hole and is inserted into the first annular groove. A first gap exists between the end part of the bolt 4 and the first annular groove in the radial direction, a second gap exists between the wall surface of the upright post 2 and the inner wall surface of the sliding chute in the radial direction, and the widths of the first gap and the second gap are equal. The screw holes are symmetrical about the axis of the upright post, the screw holes are uniformly distributed along the circumferential direction of the sliding groove, and the number of the first grooves is 2; the quantity of second slot is 4, and at 2 axis direction evenly distributed of stand, the screw is 2 at the quantity of 2 axis directions of stand, has placed ball 6 between the bottom surface of stand 2 and the spout diapire.

The specific implementation process is as follows:

the bolt 4 is inserted into the first annular groove, and since the diameter of the screw hole is equal to the width of the first annular groove, when one end of the bolt 4 is positioned in the first annular groove, no gap exists between the bolt 4 and the annular groove in the axial direction of the upright 2. When the upright post 2 has the tendency of moving along the axial direction under the action of external force, the upright post 2 is clamped by the bolt 4, so that the upright post 2 is positioned in the axial direction; similarly, when the upright post 2 has a tendency to move in the radial direction, it will be supported by the bolt 4, which will realize the positioning of the upright post 2 in the radial direction. Because the first annular groove is in a ring shape, the first annular groove can rotate under the action of external force. Therefore, the vertical column 2 can be limited and fixed from two axial and radial directions, the vertical column 2 is prevented from loosening, the vertical column 2 can be ensured to rotate, and the direction of the display panel 1 can be adjusted as required.

Example 2

The difference from the embodiment 1 is that a through hole is formed at the bottom of the base 3, the diameter of the magnet 7 is equal to the diameter of the through hole, and the length of the magnet 7 is equal to the depth of the through hole, as shown in fig. 2. When the ball 6 moves too violently, the attraction of the magnet 7 can play a certain role of buffering to ensure that the ball 6 is positioned at the middle position of the bottom of the upright 2 as far as possible.
