Description

Plastic magnetic column

Technical Field

The utility model relates to a lamp decoration accessory especially indicates to be used for the aluminium base board of LED to fix the magnetism post in the lamp.

Background

it is known that, in lighting fixtures such as ceiling lamps, in order to facilitate installation and maintenance of an LED aluminum substrate, a magnetic suction method is generally adopted to suck the aluminum substrate onto an iron lamp panel. Currently, there are two main fixing methods for fixing the magnet to the aluminum substrate:

One is a mode of adopting an iron matrix and a screw: the magnet is arranged in the iron matrix, and the iron matrix is screwed and fixed on the aluminum substrate by screws during installation, so that the cost is high, the installation is troublesome, and time and labor are wasted; in addition, the influence of the iron matrix can greatly reduce the magnetic force of the magnet, and further cause the magnet to be not firmly attracted or to be tightly attracted by a larger magnet. Meanwhile, the structure is mainly suitable for being mounted on a round hole of the aluminum substrate.

the other is that a plastic part is adopted to place the magnet, a pair of symmetrically distributed buttons are integrally formed on the surface of the plastic part in an injection molding mode, for example, a novel LED aluminum substrate magnetic column with the patent number of 2017210270307, when the novel LED aluminum substrate magnetic column is produced in large scale, because the button shape position of the button is formed by collision of a front mold and a rear mold of a mold, burrs are easy to appear on the product, the mold manufacturing cost is high, the injection molding production is unstable, the service life of the mold is short, and the production cost is high; in addition, this kind of structure only is applicable to the aluminium base board in elliptical aperture or bar hole, when the installation, aligns the button of plastic part with the rectangular of elliptical aperture or bar hole and inserts after, rotates about 90 degrees again and makes the button rotate to the short direction position department in elliptical aperture or bar hole, just so can fix the plastic part with the help of the hook portion of button. It can be seen that the plastic parts are mounted by rotating them by 90 degrees, which makes the assembly troublesome; meanwhile, the magnet is easy to be separated in the actual production process.

Disclosure of Invention

An object of the utility model is to overcome the not enough of prior art, provide a plastic magnetism post that the structure is more reasonable, simple to operate.

In order to solve the technical problem, the utility model adopts the following technical scheme:

A plastic magnetism post, includes injection moulding's plastic fixing base, magnet and magnetic sheet, wherein:

the fixed seat comprises a seat body and a conical elastic buckle arranged on the upper surface of the seat body, wherein the elastic buckle comprises a hollow inverted cone arch door consisting of two vertical edges and a connecting edge connected to the upper ends of the two vertical edges, and a sliding buckle position outside the vertical edges; a magnet containing hole is arranged in the seat body;

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

the magnetic sheet is disposed in the magnetic sheet accommodating hole.

In an improved scheme of the plastic magnetic column, the outer peripheral wall of the magnet is in a tooth shape or a tooth flower shape.

In the improved scheme of the plastic magnetic column, two ends of the cross section of the elastic buckle are both in an outward arched arc shape.

Compared with the prior art, the beneficial effects of the utility model are that: the plastic magnetic column is suitable for the aluminum substrate with a round hole as a mounting hole, when the plastic magnetic column is used, the conical part of the plastic magnetic column is pressed into the round hole by fingers, and the magnetic column can be mounted without rotating 90 degrees like the current plastic part with a pair of independent slide fasteners, so that the structure of the utility model is more reasonable and the mounting is very convenient; in addition, the permanent seat of the magnet is formed by injection molding, so that the magnet can be produced in large scale, and compared with the structure of an iron matrix and a screw, the magnet has lower production cost; meanwhile, the elastic buckle is in an arched hollow inverted cone shape, and the vertical edges with the sliding buckle positions on the two sides of the elastic buckle are connected into a whole by the connecting edge at the upper end, so that the elasticity of the buckle can be enhanced, and a forced demoulding mould structure can be adopted during injection moulding.

the invention will be described in further detail with reference to the following detailed description and accompanying drawings:

[ detailed description ] embodiments

the utility model relates to a plastic magnetism post, as shown in fig. 1 to 4, plastic fixing base 1, magnet 2 and magnetic sheet 3 including injection moulding, wherein:

The fixed seat 1 comprises a seat body 11 and a conical elastic buckle 12 arranged on the upper surface of the seat body 11, wherein the elastic buckle 12 comprises a hollow inverted cone arched door consisting of two vertical edges 121 and a connecting edge 122 connected to the upper ends of the two vertical edges 121, and a sliding buckle position 123 positioned on the outer side of the vertical edge; a magnet containing hole 111 is arranged in the base body 11;

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 11 is provided with a magnetic sheet containing hole 21;

The magnetic sheet 3 is disposed in the magnetic sheet accommodating hole 21, and forms a magnetic pole (magnet) with stronger attraction with the magnet 2 to magnetically attract the aluminum substrate into the lamp such as the lamp panel.

The utility model is suitable for an install on the aluminium base board that the mounting hole is the round hole, when the installation, insert into behind the conical elasticity knot 12 of plastic magnetism post the round hole 41 of aluminium base board 4, can when hearing "the" sound, at male in-process, elasticity is detained 12 and can be toward the extrusion deformation in the arched door, thereby let elasticity detain 12 insert the round hole 41 smoothly, elasticity is detained 12 and can automatic re-setting after that, make the hasp position 123 keep off outside the round hole 41 after, the installation of plastic magnetism post has just been accomplished, as shown in figure 5.
