Abstract

A modular fence comprises transverse bars (10), vertical bars (9) and clamping elements (3). The clamping elements (3) are non-metal elastic pieces. The vertical bars (9) are in clamped connection with the clamping elements (3) through vertical bar inserting holes (3-2) formed on the middle parts thereof. Outer rings of the clamping elements (3) are in inserted connection with the inserting holes (10A) of the transverse bars, outward flanges (3-1) are arranged at the upper end of the outer rings of the clamping elements (3). Slopes (3-5) inclining towards the inner side are arranged on the outer rings below the flanges (3-1). The lower sides of the slopes (3-5) are straight sides (3-4), the outer diameters of the straight sides (3-4) being smaller than that of the flanges (3-1) at the upper ends. Clamping groove (3-6), which are matched with the single side thickness of profiles of the transverse bars (10), are formed between the upper end faces of the slopes (3-5) and the lower end faces of the flanges (3-1). The inner ring faces of the clamping elements (3) corresponding to the slopes (3-5) on the outer ring are provided with protrusions (3-7) protruding inwards. The protrusions (3-7) extend out in a circular-arc shape from the top down, and stretch into clamping holes (9-1) in the vertical bars (9). The lower end faces (3-8) of the protrusions (3-7) abut against the openings of the clamping holes (9-1). The fence can be assembled on site, and the cost is reduced.

Description

Assembled fence

Technical field

The invention relates to an assembled fence.

detailed description

The invention will now be further described with reference to the accompanying drawings.

The utility model relates to an assembled fence, which comprises a horizontal rail 10, a vertical rail 9 and a latching member 3. The latching member 3 is a non-metallic elastic member, and the middle of the latching member 3 is a vertical column insertion hole 3-2 and a vertical column 9 is engaged. The outer ring of the clip 3 is inserted into the insertion hole 10A of the rail,

The upper end of the outer ring of the engaging member 3 has an outward flange 3-1, and the lower outer ring of the flange 3-1 is provided with an inclined surface 3-5 inclined to the inner side, and the lower side of the inclined surface is a straight side 3-4, straight The outer diameter of the side 3-4 is smaller than the outer diameter of the upper end flange 3-1, and the upper end surface of the inclined surface 3-5 and the lower end surface of the flange 3-1 are provided with a single side 10-1 of the profile of the crossbar 10. Depending on the thickness of the card slot 3-6;

The inner ring surface of the engaging member 3 corresponding to the inclined surface 3-5 on the outer ring is provided with an inwardly projecting convex piece 3-7, and the convex piece 3-7 is convexly curved from the top to the bottom. The bumps 3-7 extend into the engaging holes 9-1 provided in the vertical column 9, and the lower end faces 3-8 of the bumps 3-7 are opposed to the openings of the engaging holes 9-1 on the vertical column 9. .

A groove 3-9 is disposed in the middle of the protrusion 3-7 disposed on the inner ring surface of the engaging member 3, and at least one of the engaging holes 9-1 of the vertical column 9 is provided with a groove 3 in the middle of the protruding block 3-7. -9 matched protrusion 9-2.

The material of the clip 3 is plastic or rubber.

The inclined surface 3-5 of the flange 3-1 of the engaging member 3 inclined downward in the downward direction and the inward convex convex provided on the inner ring surface Blocks 3-7 are at least one.

The cross-sectional shape of the rail 10 may be inverted U-shaped.

The cross-sectional shape of the rail 10 may also be a rectangle. At this time, the insertion hole diameter 10A-1 of one end surface of the insertion hole 10A of the rail 10 may be larger than the insertion hole diameter 10A-2 of the opposite other end surface.

During installation, the outer ring of the engaging member 3 is inserted into the downward direction of the insertion hole 10A of the horizontal rail. At this time, the hole wall of the insertion hole 10A of the horizontal bar is in contact with the inclined surface 3-5 of the outer ring of the engaging member 3 which is inclined inward. The hole wall of the insertion hole 10A of the rail presses the slope 3-5 inward to satisfy the downward movement of the clip 3. When the clip 3 is moved down to the position of the slot 3-6, the hole wall of the insertion hole 10A of the rail releases the pressed slope 3-5, so that the slope 3-5 is ejected into the cavity between the horizontal columns. The profile single side 10-1 of the crossbar 10 is caught by the card slot 3-6; at this time, due to the action of the card slot 3-6, the profile single side 10-1 of the crossbar 10 and the clip member 3 are kept up and The downward locking relationship prevents the clip 3 from moving up or down, thereby maintaining a fixed relationship between the rubber ring and the rail.

Insert the vertical column 9 into the vertical column insertion hole 3-2 of the engaging member 3, and the vertical surface of the vertical surface of the engaging member 3 has the surface of the convex portion 3-7 protruding inward, the hole surface and the engaging member The arcuate surface contact of the bumps 3-7 on the inner ring surface of the third surface is pressed to the both sides of the bumps 3-7 of the engaging member 3 to smoothly descend the vertical column 9.

When the vertical column 9 is inserted downward to fit the position of the protrusion 3-7 which satisfies the vertical column insertion hole 3-2 and the engaging member 3, the vertical surface of the vertical column releases the protrusion 3-7 of the pressing and engaging member 3, The bump 3-7 is ejected into the snap hole 9-1 of the vertical column 9.

The vertical column 9 is continuously inserted, and the vertical surface of the vertical column is in contact with the curved surface of the convex piece 3-7 on the inner ring surface of the engaging member 3, and the convex piece 3-7 is again squeezed out of the engaging hole of the vertical column 9. 9-1, when the position of the second vertical bar engaging hole 9-1 and the inner ring surface of the engaging member 3 is exactly matched, the vertical surface of the vertical bar is released and squeezed to make the engaging member The protrusion 3-7 on the inner ring surface of the 3 is ejected into the second vertical column engaging hole 9-1. At this time, the protrusion 9-2 on the vertical column engaging hole 9-1 and the inside of the engaging member 3 The intermediate grooves 3-9 of the projections 3-7 on the ring surface are kept in a downward locking relationship, so that the vertical column cannot be continuously inserted, and the vertical column engaging hole 9-1 and the inner ring surface of the engaging member 3 are convex. The lower end faces 3-8 of blocks 3-7 remain in an upwardly locked relationship so that the vertical bars cannot be pulled up. Thereby the fixed relationship of the clip 3 to the vertical column 9 is maintained.

In the present invention, the connection structure between the rail 10, the vertical column 9, and the clip 3 can be applied to the connection of the horizontal bar, the vertical column and the door frame in the fence door, and also to the connection between the fence and the pile, see respectively Figure 6 - Figure 13.
