[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a quick-disassembly and assembly railing based on a mortise and tenon structure, which includes a column foot, a column, a cross bar and a vertical pole; the column foot is located at the lower end of the column and is clamped with the column, the two cross bars are located between the two columns and are clamped with the columns, and a plurality of vertical poles pass through the two cross bars and are connected thereto; a frame composed of the columns, the cross bars and the vertical poles forms a protective isolation zone.

[0005] The column foot comprises a circular ring arranged on the side of the bottom plate, and a limiting groove is arranged on the circular ring.

[0006] A plurality of mounting holes are arranged on the bottom plate.

[0007] A clamping column is arranged at the lower end of the column, and two connecting columns are located at the upper part of the clamping column and are arranged on the column at intervals; the clamping column and the connecting column are both laterally perpendicular to the axis of the column.

[0008] A ball head is arranged on the upper end of the column.

[0009] The cross bar is a rod-shaped body, and a plurality of through holes are arranged at intervals on the upper side along the axial direction; and slots are arranged at the two ends of the cross bar on the same side.

[0010] The vertical pole is a rod-shaped body, and a pole cap is arranged at the upper end of the pole body.

[0011] The main beneficial effects of the utility model are:

[0012] The lower end of the column is connected to the column foot by rotating clamping; the crossbar is connected to the column by clamping; the vertical pole and the crossbar are connected by insertion; the overall structure is a mortise and tenon structure, which is convenient and efficient to install and disassemble.

[0013] There are card slots on the same side of both ends of the cross bar. During the installation process, after the two columns are fixed, the opening directions of the card slots on the two cross bars are opposite. After the cross bar is connected with the connecting column on the column, the column passes through the two cross bars to limit the cross bar from separating from the column, which has good stability.

[0021] like Figure 1~Figure 5 A quick-disassembly and assembly railing based on a mortise and tenon structure is disclosed, which includes a column base 1, a column 2, a cross bar 3 and a column 4; the column base 1 is located at the lower end of the column 2 and is clamped with the column 2, two cross bars 3 are located between the two columns 2 and are clamped with the column 2, and multiple columns 4 pass through the two cross bars 3 and are connected thereto; a frame composed of the column 2, the cross bar 3 and the column 4 forms a protective isolation zone.

[0022] In a preferred embodiment, the column foot 1 comprises a circular ring 12 disposed on the upper side of the bottom plate 11, and a limiting groove 13 is disposed on the circular ring 12. When in use, the bottom plate 11 contacts the ground, which enlarges the contact area with the ground and improves the stability of the column 2.

[0023] In a preferred solution, a plurality of mounting holes 14 are provided on the bottom plate 11. When in use, the fastening screws pass through the mounting holes 14 and are connected and fixed to the ground.

[0024] In a preferred solution, a clamping column 21 is provided at the lower end of the column 2, and two connecting columns 22 are arranged on the upper part of the clamping column 21 at intervals on the column 2; the clamping column 21 and the connecting column 22 are both laterally perpendicular to the axis of the column 2. When in use, the column 2 is perpendicular to the ground and perpendicular and parallel to each other, and the clamping columns 21 on the two columns 2 correspond to each other.

[0025] Preferably, the clamping column 21 on the column 2 is a circular column; the limiting groove 13 on the column foot 1 is an L-shaped opening structure; after the clamping column 21 on the column 2 is inserted into the limiting groove 13 on the column foot 1, the column 2 can be rotated to connect the column 2 and the column foot 1 into a whole.

[0026] In a preferred embodiment, a ball head 23 is provided at the upper end of the column 2. When in use, the ball head 23 at the upper end of the column 2 has a smooth transition to avoid hurting pedestrians.

[0027] In a preferred embodiment, the cross bar 3 is a rod-shaped body, and a plurality of through holes 31 are arranged at intervals along the axial direction on the upper side surface; and a clamping groove 32 is arranged at the same side at both ends of the cross bar 3. When in use, the opening directions of the clamping grooves 32 on the two cross bars 3 are opposite, and the through holes 31 on the two cross bars 3 correspond to each other vertically and are located on the same axis.

[0028] Preferably, the connecting column 22 is a square column; the clamping slot 32 is a square open slot; the square column and the square open slot are stable after being clamped.

[0029] In a preferred solution, the vertical rod 4 is a rod-shaped body, and a rod cap 41 is arranged at the upper end of the rod body. When in use, the rod cap 41 on the vertical rod 4 restricts the vertical rod 4 from completely passing through the upper cross bar 3.

[0030] Preferably, during the installation process, the columns 2 are perpendicular to the ground, and the clamping columns 21 on the two columns 2 correspond to each other. Since the same side of both ends of the cross bar 3 is provided with a clamping groove 32, after the two columns 2 are fixed, the opening directions of the clamping grooves 32 on the two cross bars 3 are opposite. After the cross bar 3 is clamped with the connecting columns 22 on the columns 2, the column 4 passes through the two cross bars 3 to limit the cross bar 3 from being separated from the column 2, and the stability is good.
