Detailed ways

It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

1-9 illustrate some embodiments in accordance with the present invention.

As shown in Figures 1 to 7, a tool-free and quick disassembly fence includes a column 1, a base 2, and a wall 3. The base 2 is fixed to the ground through anchor bolts 21, and the column 1 is installed on the base 2, and It is clamped with the base 2, and the two sides of the wall body 3 are respectively clamped with the column 1, so that the column 1 and the wall body 3 can be quickly disassembled and assembled without tools through the connection method of the buckle, which improves the disassembly and assembly efficiency and reduces the use conditions; , the column 1 and the base 2 constitute a fence support column.

Specifically, as shown in FIG. 2 , the base 2 is a hollow quadrangular platform, and several installation holes are provided at the four corners of the base 2. By inserting anchor bolts 21 into the installation holes, the base 2 can be fixed to the ground. The middle part of 2 is provided with a snap hole 22 for installing the upright column 1 , wherein the snap hole one 22 penetrates the upper and lower end surfaces of the base 2 .

Specifically, as shown in FIGS. 3 and 4 , the upright column 1 includes a long column body 14 , a bottom plate 13 installed at the bottom of the column body 14 , a rotating shaft 12 installed on one side of the bottom plate 13 , and a buckle connected with the rotating shaft 12 . 11, wherein the bottom plate 13 is fixedly connected to the cylinder 14 by screws, the buckle one 11 is rotatably connected to the bottom plate 13 through the rotating shaft 12, and the outer ring of the rotating shaft 12 is fixedly connected to the buckle one 11, so that the rotating shaft 12 can be driven The buckle one 11 rotates around the bottom plate 13, which makes the operation more convenient.

As shown in Figures 8 and 9, the buckle one 11 is a plate-like structure similar to a rectangle, and has four corners, including two diagonally arranged right angles and two diagonally arranged arc chamfers. Arc chamfers and right-angled sections are used to ensure that only one-way rotation is possible.

Among them, the shape of the buckle hole one 22 matches that of the buckle one 11. When the column 1 is matched with the base 2, the buckle one 11 is first inserted into the buckle hole one 22, and extends into the lower end of the base 2, and then By rotating the rotating shaft 12, the buckle one 11 is rotated 90° counterclockwise to abut the lower end surface of the base 2 to prevent the buckle one 11 from falling off the buckle hole one 22, so that the column 1 can be installed on the upper end of the base 2 more stably. When it needs to be removed, it is only necessary to continue to rotate the buckle 11 counterclockwise by 90°.

Specifically, as shown in FIGS. 5-7 , the two ends of the wall 3 are provided with two buckles 31 , the left and right sides of the column 14 of the upright column 1 are provided with two buckle holes 15 , and the second buckle holes 15 and the second buckle The installation position, height and shape of 31 are matched, so that the wall 3 can be detachably fixed between the two columns 1, so that the column 1 and the wall 3 can be quickly disassembled and assembled by means of a snap connection.

Among them, the second buckle 31 is a flat sheet metal part, including an installation and fixing part 311 and a clamping part 312. The installation and fixing part 311 has a number of installation holes, and the second buckle 31 can be installed on the wall 3 by passing screws through the installation holes. On the upper side, the snap portion 312 is L-shaped, and forms a bayonet with the mounting and fixing portion 311. The corner of the L-shaped snap portion 312 is chamfered, so that the second snap 31 can be inserted into the snap hole 2 15 more easily. When the vertical dimension of the second snap hole 15 is slightly smaller than the vertical dimension of the L-shaped snap portion 312, the second snap 31 can still be inserted into the second snap hole 15. In addition, since the size of the second snap hole 15 is reduced , which can make the two fit more closely and not easily fall off.

In one embodiment, as shown in FIGS. 2 and 3 , the middle of the buckle 11 protrudes along the width direction to form two symmetrical circular arc sides, the diameters of the two circular arc sides are close to the diameter of the rotating shaft 12, and the circular The arc edge can increase the contact surface between the buckle 11 and the rotating shaft 12, so that the two are connected more firmly.

In one embodiment, as shown in FIGS. 4 and 5 , the column 14 is a profile with a special-shaped section, wherein the section of the column 14 includes a central rectangular cavity 1 141 , and two outer rectangular cavities 142 and two The third rectangular cavity 143 and the two rectangular cavity two 142 are disposed axially symmetrically with respect to the rectangular cavity one 141 , and the two rectangular cavity three 143 are also disposed axially symmetrically with respect to the rectangular cavity one 141 .

The second rectangular cavity 142 is disposed close to the long side of the rectangular cavity 1 141 , and a wide side of the rectangular cavity 2 142 is collinear with a wide side of the rectangular cavity 1 141 , and the long side of the rectangular cavity 1 141 is the same as the rectangular cavity 2 142 . One long side is shared, and the length of the long side of the second rectangular cavity 142 is greater than the length of the long side of the rectangular cavity 1 141 , so that the rectangular cavity 2 142 protrudes from the rectangular cavity 1 141 in the length direction.

In addition, the third rectangular cavity 143 is perpendicular to the second rectangular cavity 142 , one short side of the third rectangular cavity 143 is collinear with one long side of the second rectangular cavity 142 , and one long side of the third rectangular cavity 143 and the short side of the second rectangular cavity 142 Collinear; wherein, the second snap hole 15 is arranged on the third rectangular cavity 143 or the second rectangular cavity 142 .

When connecting the two walls 3 to the upright column 1 at the same time, different snap holes 15 can be selected according to the included angle of the two walls 3 . When the two walls 3 are parallel, the two snaps 31 on the two walls 3 can be connected to the two snap holes 15 at the position of the rectangular cavity 3 143 on the column 14. When the two walls 3 are vertically arranged , the buckle 2 31 on one wall 3 is connected with the buckle hole 2 15 at the position of the rectangular cavity 3 143 on the column 14 , and the buckle 2 31 on the other wall 3 is connected with the rectangular cavity 2 142 on the column 14 The two snap holes 15 at the positions are connected, so that the two walls 3 are vertically arranged.

Among them, the inner side of the outermost corner of the rectangular cavity 3 143 and the rectangular cavity 2 142 is provided with a thickened part, and a through hole 144 is opened in the middle of the thickened part. The through hole 144 can be set by screws. The two profiles can also be connected together by inserting a pin into the through hole 144 to form a longer column 14, which is convenient for on-site construction, and can also be connected with the through hole 144 by screws. A blocking cover is installed on the upper end of the body 14 to prevent rainwater and foreign objects from falling into the interior of the column body 14 and prolong the service life of the column body 14 .

At the same time, the lengthwise dimension of the second rectangular cavity 142 and the third rectangular cavity 143 is much larger than the widthwise dimension. This arrangement can increase the length and width of the cross section of the column 14 and increase the stability of the column.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
