Description
Technical field
The utility model is related to arrive connection apparatus field more particularly to a kind of magnetic-suction type fixing device.
Background technology
At present for the connection type between room temperature lower plane, mainly using being bolted.It has simple in structure, company
The advantages of connecing reliable, convenient disassembly, but for certain specific occasions, bolt connecting mode is just less applicable in.Such as：In magnetic conduction
The installation of metal side is relatively-stationary when piece installing, when magnetic conductive metal surface is unable to processing screw hole, then bolt can not be used to connect
It connects.And magnetic-type Plane Installation mode just can be good at solving the problems, such as this.
Traditional magnetic mode is that magnet steel insertion is directly waited for piece installing, i.e., is embedded in magnet steel and needs to install fixed parts
Interior, the characteristics of other end is adsorbed on fixed magnetic conductive metal surface, this mode is small, and magnet steel facilitates insertion to wait for piece installing,
On appearance without influence.Its disadvantage is led it is also obvious that magnetic force size when this traditional magnetic mode can not adjust adsorbing plane
Cause installing and dismounting very inconvenient, and the lateral force that can be born is fairly limited.
Publication No. CN 201608013U, publication date are that the Chinese patent literature on October 13rd, 2010 discloses one kind
The magnetic decorative carrier device of freely-removable, suitable for being fixed on the plane body surface with iron plate, it is characterized in that：Including dress
Adorn interposer carrier, decorate on the side wall of interposer carrier and be provided with magnetite embedded groove, be provided with magnetite in magnetite embedded groove, magnetite with it is flat
It is provided with resin glue between the body surface face of face, decorates magnetic attraction of the interposer carrier by magnetite and iron plate in its embedded groove, and
Pull of vacuum between resin glue and plane body surface is securely seated between on plane body surface.
The magnetic decorative carrier device of freely-removable disclosed in the patent document, by magnetite and plane body surface it
Between resin glue is set, coordinate the magnetic attraction of magnetite and iron plate, although its fixed degree on plane body surface can be improved,
But since structure design is unreasonable, there are following defects：
1, magnetic force size when it can not adjust adsorbing plane, causes installing and dismounting very inconvenient, and especially installation is empty
Between narrow occasion, when installation fee is particularly evident.
2, decoration interposer carrier and plane body surface is plane contact, and friction coefficient is small, when decorate interposer carrier weight compared with
When weight, decoration interposer carrier is difficult to be firmly fixed to plane body surface, is easy to fall off.
Utility model content
The utility model provides a kind of magnetic-suction type fixing device, this practicality is new to overcome the defect of the above-mentioned prior art
Type can effectively adjust magnetic force size when absorption magnetic conductive metal surface, easy for assemble or unload, and it is narrow to be particularly suitable for installation space
