There is a gap, the left side wall and the right side wall are provided with fixing holes and joint holes, the second half of the left side wall and the right side wall are gradually reduced, and the middle part of the rear side wall is provided with a vertical groove. It is divided into a bottom surface and a left and right side surface, and a through hole is arranged on the bottom surface.

As an improvement of the present invention, the notch is a square notch, and the height of the notch is 2/3 of the height of the left side wall and the right side wall.

As an improvement of the present invention, the width of the notch is half of the width of the left side wall and the right side wall.

As an improvement of the present invention, there are two fixing holes arranged in a vertical direction.

As an improvement of the present invention, the fixing hole is a waist-shaped hole.

As an improvement of the present invention, the connection hole is a square hole.

As an improvement of the present invention, the angle between the left and right sides of the groove and the bottom surface is 60°, and the width of the bottom surface of the groove is smaller than the width of the outlet of the groove.

As an improvement of the present invention, the depth of the groove is 1/4 of the width of the left side wall and the right side wall.

As an improvement of the present invention, the outer surface of the metal plate is galvanized.

The beneficial effects of the present invention are:

A pressure alarm fence column head according to the present invention adopts a segmented structure and can be installed on the fence column in a pyramid style. It is easy to install, has an ingenious structure, is durable, and the M-shaped design can increase the strength and realize the overall performance. Improvement and long service life.

Detailed ways

The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

As shown in the figure, a column head of a pressure alarm fence according to the present invention, the column head is bent into a hollow column by a metal plate and extends in the vertical direction, including a rear side wall 1, a left side wall 2, a right side wall Wall 3, the front ends of the left side wall 2 and the right side wall 3 are bent inward at right angles to form opposite first free ends 4 and second free ends 5, and the vertical directions of the two free ends 4 and 5 are respectively A row of connecting holes 6 is provided, a gap 7 is provided in the upper part of the left side wall 2 and the right side wall 3, a fixing hole 8 and a combination hole 9 are provided on the left side wall 2 and the right side wall 3, the left side wall 2, The second half of the right side wall 3 gradually shrinks, and the middle part of the rear side wall 1 is provided with a vertical groove 10. The groove 10 is divided into a bottom surface 11 and left and right sides 12, 13.

A column head of a pressure alarm fence according to the present invention has the same cross-sectional shape as that of the column, and can be installed on the fence column through a pyramidal connecting piece during installation. It is easy to install and adopts a segmented structure. , the structure is ingenious, the front end of the column head is equipped with a pressure plate through a square hole, and the column head is connected with the mesh. The fixing hole 8 on the side wall 3 fixes the alarm device, and the connecting hole 9 is connected with the connecting block. The shape of the cross-section of the entire column head is M-shaped.
