Abstract
The electric fixer of the present invention is a hollow box or frame with screw pair to fix electric article. It is used in fixation of built-in switch, socket, ceiling fan regulator, wall lamp and other electric articles on wall.
Description
The invention belongs to electric product, is a kind of electrical equipment fixture.
The fixture of known built-in switch socket is by four planks or the hollow box made by five plastic plates.Sandwich in the wall hole with voussoir when hollow box uses, built-in switch socket is screwed on its end face.Wood box cost height uses timber to be unfavorable for environmental protection in a large number.Screw hole field fabrication above the Wood box is taken a lot of work, qualification rate not high (because the arborescence difference of timber, what have is not suitable for tapping, cracking is arranged when tapping or the phenomenon of can not attack silk is arranged).Because screw hole is defective, electrical equipment is fixing built on the sand.Wood box easily shrinks, easily becomes flexible, and fixes built on the sand.Plastic casing rigidity is low, and stressed back is yielding easy to crack, and loosening easily fixing built on the sand used dangerous.Because distortion screw hole position easily misplaces, installs difficulty, takes a lot of work, and uses inconvenient.The hollow box of a kind of irony of Xiao Shouing in the market, rigidity increases, but still not high enough, stressed after still distortion.The hollow box that sheet iron is made, the one, the cost height.The 2nd, on-insulated, exist potential safety hazard.The 3rd, do not guarantee fixing firm technical guarantee.Hollow box has certain specification, and the wall aperture differs in size, so voussoir needs on-the-spot single making, also is difficult for producing qualified voussoir when taking a lot of work, more difficult, use inconvenience that installation effectiveness is low, installation is difficult, change is installed.Voussoir contacts with hollow box end face line, and contact area is little, becomes flexible easily, fixes built on the sand.Hollow for a long time box exists and uses inconvenience, fixing unsteady technical barrier.
The objective of the invention is to provide a kind of, easy to use, fixing firm electrical equipment fixture.
A kind of electrical fixer of the present invention, it comprises hollow box or framework, it is characterized in that: further comprising thread part (1) and thread part (2), two thread parts (2) and hollow box or framework loose joint connect with thread part (1); Perhaps thread part (1) two ends and hollow box or framework loose joint connects with thread part (2); A perhaps end of thread part (1) and thread part (2) and hollow box or framework loose joint, the other end links.
A kind of electrical fixer of the present invention is characterized in that: it comprises joining thread part (1) and thread part (2), have on the thread part outer surface fixing electrical equipment screw hole or hole or screw; Perhaps it comprises joining thread part (1) and thread part (2), and connector has the fixedly screw hole or the hole of electrical equipment above the connector, and connector connects with thread part.
The localization part that restricted thread part rotates on hollow box or the framework.
About having, the thread part two ends revolve screw thread.
The present invention is a loose joint screw thread pair on a hollow box or the framework; Perhaps establish fixedly screw hole or the hole or the screw of electrical equipment in appearance at screw thread pair; Perhaps on screw thread pair, establish connector, establish the fixedly screw hole or the hole of electrical equipment on the connector; And the screw thread pair fixture that constitutes.Loose joint screw thread pair on a hollow box or framework effectively utilizes the inner rich space of hollow box or framework, establishes external shape, combination flexibly ingeniously.Set up screw thread pair, do not increase volume, do not influence electric wire and install, do not tie up concealed installation electrical equipment position.Screw thread pair plays fixation, and hollow box or framework play skeleton function, plays connecting thread secondary and wall electrical equipment and the effect of fixed wall electrical equipment.On the screw thread pair outer surface, establish fixedly screw hole or the hole or the screw of electrical equipment; Perhaps establish connector on screw thread pair, establish the fixedly screw hole or the hole of electrical equipment above the connector, simple and compact for structure, volume is little, help electric wire, electrical equipment is installed.Screw thread pair plays fixation, and screw hole on its outer surface or hole or screw play the effect of fixed wall electrical equipment.Connector plays the effect of connecting thread pair and wall electrical equipment, the effect of fixed wall electrical equipment.This fixture is skillfully constructed, and is reasonable in design, simple in structure and exquisite.The screw thread pair bed knife is big, has self-locking action, fixing firm.Put wall hole rotation thread part during use into and just can fix, reverse rotation can be unclamped, and uses extremely convenient and strength-saving saving of labor.The wall aperture is not had specific (special) requirements,, make things convenient for the applicability extra-heavy as long as construction routinely because screw thread pair has enough adjusting ranges of establishing, installs and fixes to be fit to different apertures.Because thread part end face and hole wall contacts contact face are long-pending big, and be stressed little on the unit are, can not be out of shape, just can not become flexible yet, thereby fixing firmly.The vertical hole wall of screw thread pair is fixed, its axial carrying capacity height, fixing firmly can not being out of shape, on the screw thread pair outer surface fixedly the position of the screw hole of electrical equipment or hole or screw can not misplace yet; Hollow box or framework or connector with the screw thread pair loose joint do not bear fastening force, can not be out of shape, and the position that is located at hollow box or framework or screw hole above the connector or hole just can not misplace yet.Since the fixing correct position of electrical equipment, easy, the convenient and strength-saving saving working hour of electrical equipment installation.In sum, so can realize the invention provides a kind of, easy to use, as to fix firm electrical equipment fixture purpose.
Owing to adopt such scheme, following advantage arranged:
1, screw thread pair fixture fastening force is big, has self-locking action, and fixing is firm, guarantees to install and fix quality.
2, the thread part end face contacts with hole wall, and contact area is big, stressed little on the unit are, can not be out of shape, and guarantees to install and fix quality.
3, guarantee to install and fix quality, improve the security reliability of product and be fixed electrical equipment and electrical appliance.
