Abstract
The utility model discloses an insulating plate bolt fixing structure which solves the problem that an existing bolt fixing structure is complex in mechanism. The insulating plate bolt fixing structure comprises a base plate and at least one bolt perpendicularly installed on the base plate. At least one bolt hole is formed in the base plate. A threaded rod of each bolt penetrates through the corresponding bolt hole and partly extends out of the base plate. One side face of the base plate is provided with a fixing groove. A bolt head of each bolt is placed in the fixing groove and is a non-circular head. The shape of the fixing groove is matched with that of the bolt heads so that the bolts can be prevented from rotating. The groove depth of the fixing groove is not smaller than the length of the bolt heads. An insulating material is machined into the insulation plate bolt fixing structure with a certain shape, the bolt heads are clamped through the structure, and then parts to be connected are installed and fastened after the bolt heads are used in cooperation with nuts.
Description
Technical field
The utility model relates to a kind of insulation board bolt fixed structure.
Background technique
Using screw bolt and nut connection activity component is one of topmost modes of component mechanical connection, its quick and easy, easy disassembling.But some occasion, due to the spatial constraints or the insulating requirements restriction that are connected between component, in fastening, bolt or nut can not block, and causing cannot be fastening.The patterns that adopt tapping on metal parts, insulating material die sinking moulding by casting embedded nut at present more.
Existing bolton mode exists some defects and deficiency:
1) tapping on metallic element, fitted bolt is fastening, in different potentials electrical connection situation, cannot meet insulating requirements;
2) die sinking is used insulating material cast embedded nut, complex structure, and cost is higher.
Model utility content
In order to overcome the baroque deficiency of existing bolt fixed structure, the utility model aims to provide a kind of insulation board bolt fixed structure, this fixed structure by insulating material machining definite shape structure out, by this structure card kingbolt head, and then be used in conjunction with nut to needs connect component install fastening.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of insulation board bolt fixed structure, comprise that substrate and at least one are vertically mounted on the bolt on substrate, on this substrate, have at least one bolt hole, the screw rod of each bolt stretches out described substrate through corresponding bolt hole and part screw rod, and the spiro rod section that stretches out described substrate has outside thread; Its structural feature is, on a side of described substrate, has fixed groove, and the bolt head of described bolt is placed in described fixed groove, and the bolt head of described bolt is non-round end, and described fixed groove is the shape matching with bolt head shape, to prevent that bolt from rotating; The groove depth of described fixed groove is not less than the length of bolt head; On described substrate, be contained in the top sealing plate for stoping bolt axial float.
What deserves to be explained is, bolt of the present utility model is vertically mounted on substrate, is not definitely vertical on geometric meaning, but vertical in engineering application, can the certain angle of permissible error.The utility model part screw rod stretches out described substrate and is mainly used for being outward threaded with miscellaneous part.
Be below the technological scheme of further improvement of the utility model:
As a kind of concrete structural type, described substrate has on the side of fixed groove and has locating slot, and described top sealing plate has positioning convex, and described positioning convex coordinates and is connected with locating slot.Further, described locating slot is dovetail groove.
As the concrete structural type of another kind, described substrate and the plate that binds are fixedly linked by fastening piece.
As the concrete structural type of another kind of the present utility model, the screw rod of described bolt is divided into two-part, the first portion being connected with bolt head, and the second portion being connected with first portion and stretch out described substrate; The cross section of described first portion is non-circular, and the cross section of second portion is circular, and second portion has outside thread; Described bolt hole is the shape matching with described first portion.Further, the cross section of described first portion is square, and described bolt hole is square hole.
Preferably, described fixed groove is square groove, and bolt head is square.
Preferably, described fixed groove is Hexagon groove, and bolt head is Hexagon.
Preferably, described fixed groove is quincunx groove, and bolt head is quincunx.
By said structure, the utility model is specially adapted to due to space or insulating requirements restriction, and connected component can not use screw bolt and nut to carry out fastening occasion simultaneously.Can be used as wire board, dunnage, mounting base etc.The structure grooves of machining definite shape and hole on insulated substrate, by bolt, through hole, bolt head is stuck among structure grooves, removes stuck bolt by the structure of groove, and then removes to shut the bolt head in substrate by insulation shrouding.Its mechanical strength meets usage requirement, and insulating property are reliable, is easy to processing, manufacturing process and the cost of material is low, double thread carries out overall immersion oil paint after paints and lacquers protection, and outward appearance is beautiful.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple for structure, installation and maintenance are convenient, fastening piece is few, save space.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Brief description of the drawings
Fig. 1 is an embodiment's of the utility model structure principle chart;
Fig. 2 is the utility model insulated substrate structural representation;
Fig. 3 is that the utility model uses schematic diagram as wire board;
Fig. 4 is that the A-A of Fig. 2 is to sectional view;
Fig. 5 is the left view of Fig. 2.
Embodiment
A kind of insulation board bolt fixed structure, referring to accompanying drawing 1-2, described structure is by insulated substrate in Fig. 11, top sealing plate 2 and hexagon head bolt 3 assemblings realize.When the utility model is installed, need first by the fixed groove of hexagon head bolt 3 setting-in insulated substrates 1, ensure that bolt head can not exceed the degree of depth of groove.Top sealing plate 2 is pushed in along the locating slot 11 on insulated substrate 1 again, determine shrouding and have the positioning convex 10 coordinating with locating slot, locating slot 11 is preferably dovetail groove, can complete assembling.Thickness, length, shape, the shape and structure of fluting and the specification of setting-in hexagon head bolt of insulated substrate and the aperture of whole two ends mounting hole can be designed according to actual needs.Top sealing plate 2 is accepted or rejected according to practical situations.
Fig. 3 is a kind of application example of the utility model while using as wire board.Insulated substrate 1, top sealing plate 2, hexagon head bolt 3 have been assembled rear (entirety becomes wire board assembly), use construction bolt 4 that wire board assembly is fixed on above mounting plate 8.Then copper bus wire 5 is enclosed within above hexagon head bolt 3, loads onto the parts that other need to be fixing in the lump simultaneously, as tenminal block 6 etc.Finally use tightening nut 7, compression spring, the flat gasket fastening good associated fasteners of moment on request.
The structure grooves of machining definite shape and hole on insulated substrate, by bolt, through hole, bolt head is stuck among structure grooves, removes stuck bolt by the structure of groove, and then removes to shut the bolt head in substrate by insulation shrouding.Its mechanical strength meets usage requirement, and insulating property are reliable, is easy to processing, manufacturing process and the cost of material is low, double thread carries out overall immersion oil paint after paints and lacquers protection, and outward appearance is beautiful.
