[ detailed description ] embodiments

The utility model relates to a plastic magnetism post, as shown in fig. 1 to 5, plastic fixing base 1, magnet 2 and magnetic sheet 3 including injection moulding, wherein:

the plastic fixed seat 1 comprises a seat body 11, a pair of elastic buckles 12 and an elastic buckle connecting bridge 13, wherein the pair of elastic buckles 12 and the elastic buckle connecting bridge are arranged on the upper surface of the seat body 11; the pair of elastic buckles 12 and the elastic buckle connection bridge 13 are perpendicular to each other in a top view direction; the elastic buckle connecting bridge 13 is n-shaped, and comprises two vertical edges 131 and a cross beam 132 connected between the two vertical edges 131; the upper ends of a pair of elastic buckles 12 are respectively connected with the front and rear positions of the lower end of the beam 132 in a hanging way, and the buckling positions of the pair of elastic buckles 12 protrude out of the beam 132; the length L of the elastic buckle connection bridge 13 in the plan view direction is larger than the width W so that the plastic magnetic pillar fits into the strip-shaped hole 41 of the aluminum substrate 4, and the length and the width of the strip-shaped hole 41 are slightly larger than the length L and the width W of the elastic buckle connection bridge 13 in the plan view direction, respectively.

The magnet 2 is arranged in the magnet containing hole 111 of the seat body 11 in a tight fit manner, and the bottom of the magnet 2 is provided with a magnetic sheet containing hole 21;

the magnetic sheet 3 is arranged in the magnetic sheet accommodating hole 21 of the magnet 2, and forms a magnetic column with stronger attraction with the magnet 2 to magnetically attract the aluminum substrate into lamps such as a lamp panel and the like.

When the plastic magnetic pole is installed in the strip-shaped hole 41 of the aluminum substrate 4, the elastic buckle connecting bridge 13 of the plastic fixed seat 1 is inserted after being aligned with the length direction of the strip-shaped hole 41, and at this time, under the action of the hole wall in the width direction of the strip-shaped hole 41, the pair of elastic buckles 12 swing towards the inside of the cross beam 132 so that the elastic buckle connecting bridge 13 is smoothly inserted into the strip-shaped hole; when the plastic magnetic pole is inserted into the aluminum base plate, the elastic buckle 12 is reset and is blocked outside the strip-shaped hole 41, so that the plastic magnetic pole is installed in the strip-shaped hole of the aluminum base plate, as shown in fig. 6.

It can be seen from the above that, the plastic fixing seat 1 connects the pair of elastic buckles 12 in a hanging manner through the "n" type elastic buckle connecting bridge 13, so that the elastic buckles 12 can swing with the bottom of the cross beam 132 of the elastic buckle connecting bridge 13 as a swing point and then retract into the bottom of the cross beam, thus the elastic swing amplitude of the elastic buckles is large, and the plastic magnetic column can be inserted into the strip-shaped hole of the aluminum substrate more conveniently and more labor-saving; and because elasticity is detained and can not deviate from the bar hole of aluminium base board under the reset state, then can fix aluminium base board to the lamp panel more reliably, consequently the utility model discloses a structure is more reasonable, the installation is used more laborsavingly, uses more reliably.

Preferably, the inner side of the lower end of the elastic buckle 12 is provided with a rib 122 for preventing the elastic buckle 12 from opening outwards when being pulled, when the plastic magnetic pillar is installed in the bar-shaped hole 41 of the aluminum substrate 4, the front surface of the rib 122 contacts with the wall of the bar-shaped hole 41 in the width direction, when the plastic fixing seat is pulled outwards, the rib 122 of the elastic buckle 12 blocks the wall of the bar-shaped hole 41 in the width direction, so as to prevent the elastic buckle from opening outwards and deforming when being pulled, and we know that the plastic magnetic pillar is easy to come off the bar-shaped hole 41 of the aluminum substrate 4 once the elastic buckle deforms, and therefore the rib 122 arranged at the lower end of the elastic buckle 12 helps to prolong the service life of the plastic magnetic pillar.
