Abstract
The invention relates to a replacement-free fixing device for an electric junction box buried in wall in a concealed manner. The replacement-free fixing device comprises a fixing clamp body, a slidable inverted trapezoidal block and a bolt, wherein the fixing clamp body is a rectangular frame body comprising an internally-embedded inverted trapezoidal frame, the slidable inverted trapezoidal block is clamped in the internally-embedded inverted trapezoidal frame, the bolt penetrates through the fixing clamp body to be connected with the slidable inverted trapezoidal block, the slidable inverted trapezoidal block is driven to slide in the internally-embedded inverted trapezoidal frame up and down; when the replacement-free fixing device is used, the fixing device is arranged in the electric junction box and is closely fitted to the inner side wall of the electric junction box, the slidable inverted trapezoidal block is pushed downwards by the bolt to extrude the side edge of the internally-embedded inverted trapezoidal frame, the rectangular frame body is deformed and two sides of the rectangular frame body are enabled to be closely fitted to the electric junction box, and the electric junction box and the rectangular frame body are fixed together through friction force generated by extrusion. According to the replacement-free fixing device, the whole electric junction box is replaced without hole cutting on the wall, the maintaining time is improved, the used material is simple, the cost is reduced and the environmental protection requirement is met.
Description
Technical field
The present invention relates to one and secretly bury electrical junction box within the walls, especially relate to one and secretly bury electrical junction box within the walls and exempt to change fixture.
Background technology
Secretly burying terminal box is must obligato electric device in all kinds of building; be generally used in the method that on box body, punching bolt is fixing to fix; but construction and routine use process in often can run into secretly bury terminal box damage; especially the nut of fixed panel cannot use after dropping; now need cutter wall to take out electrical junction box; one is that to affect body of wall attractive in appearance, and two are the increase in workload and building waste.
Existing solution is secretly buried electrical junction box within the walls exempt to change fixing card as Chinese patent CN103401192A is provided one, this patent is by two U-shaped fixing cards, what utilize the outer clamping force that rises of self to be fixed on to have damaged secretly buries in electrical junction box within the walls, the deficiency of this patent is placed on after in terminal box not easily to take out, and upper and lower two set bolts are not easily aimed at, even if also can affect tension after aiming at, consumptive material is relatively some more.
Summary of the invention
The present invention in order to solve in prior art the problem of secretly burying and must to open wall after electrical junction box damages and changing, provide a kind of need not open wall hole change whole terminal box, the electrical junction box that secretly buries within the walls that reduces costs exempts to change fixture.
Object of the present invention can be achieved through the following technical solutions:
One is secretly buried electrical junction box within the walls and is exempted to change fixture, comprise fixing card, slip inverted trapezoidal block and bolt, described fixing card is the rectangle framework comprising an embedded inverted trapezoidal frame, described slip inverted trapezoidal block is fastened in embedded inverted trapezoidal frame, described bolt is connected with slip inverted trapezoidal block through fixing card, drive slip inverted trapezoidal block to slide up and down in embedded inverted trapezoidal frame, the short base place of described embedded inverted trapezoidal frame is an opening;
During use, described fixture to be placed in electrical junction box and to be close to madial wall, slip inverted trapezoidal block is promoted downwards by bolt, slip inverted trapezoidal block extrudes the side of embedded inverted trapezoidal frame, make rectangle framework generation deformation, the both sides of rectangle framework tightly touch electrical junction box, produce frictional force electrical junction box and rectangle framework are fixed together by extruding.
Described fixing card is formed by curved the establishing of an elastic sheet.
Described elastic sheet is iron plate.
Described slip inverted trapezoidal block is inverted trapezoidal duroplasts block.
Described fixing card inserts electrical junction box with the embedded inverted trapezoidal frame direction that Open Side Down.
Described slip inverted trapezoidal block is similar trapezoidal to embedded inverted trapezoidal frame.
Described embedded inverted trapezoidal frame is positioned at the side of rectangle framework.
Adopt this device need not open wall to hole and change whole terminal box, bring great convenience to electrical install and maintenance, shorten the time of maintenance, improve operating efficiency; And simple with material, reduce cost; Hole can not produce building waste due to wall need not be opened, meet the requirement of environmental protection construction.
Compared with prior art, the present invention has the following advantages:
(1) fixture of the present invention makes rectangle framework generation deformation by the movement of slip inverted trapezoidal block, thus electrical junction box and rectangle framework are fixed together, when electrical junction box damages, wall need not be opened hole and change whole terminal box, bring great convenience to electrical install and maintenance, shorten the time of maintenance, improve operating efficiency;
(2), when fixture is pulled down by the present invention, only need to make slip inverted trapezoidal block moves by bolt, embedded inverted trapezoidal frame is shunk, can fixture be taken out, convenient disassembly;
(3) rectangle framework of the present invention only need be formed by curved the establishing of an iron plate, simple with material, reduces cost;
(4) hole can not produce building waste due to wall need not be opened, meet the requirement of environmental protection construction;
(5) the present invention moves slip inverted trapezoidal block by bolt, and the bolt moved downward plays the thin iron in card top simultaneously to be forbidden moving towards two horizontal directions, to ensure the side plate of effective " extruding " terminal box of rectangle framework;
(6) bolt of the present invention is successively by rectangle framework side and slip inverted trapezoidal block base, and two thin iron add the intensity of exempting bolt and moving upward.
