Abstract
The utility model belongs to structure technique for fixing field, a kind of linkage structure for track 8 word hole of special design.The technical program comprises track 8 word hole (1), T-shaped bolt (2), equipment to be installed (3) and gland nut (4), its maximum feature is provided with boss (5) at the root of T-shaped bolt (2) screw rod, gland nut (4) bottom is provided with tightening hoop (6), when gland nut (4) is fixing with T-shaped bolt (2), boss (5) screws in tightening hoop (6) and is expanded, namely achieve tightening hoop (6) and the interference fit in 8 word holes, again location is achieved to structure.Solve the technical problem of prior art mounting structure complexity, complex operation.
Description
Technical field
The utility model belongs to structure technique for fixing field, a kind of linkage structure for track 8 word hole of special design.
Background technique
The equipment that civil aircraft passenger seat, kitchen, lavatory etc. are installed on aircraft floor, selects track 8 word hole to connect usually.Fig. 1 is section connecting element.The moulding of such link is complicated, and occupied area is comparatively large, and higher to the requirement of equipment interface, positional accuracy and moulding process, what have also needs the special tools such as chuck, and dismounting efficiency is relatively low.
Summary of the invention
The purpose of this utility model is, provides a kind of structure simple, the easy-to-mount linkage structure for track 8 word hole.
The technical solution of the utility model is, described linkage structure comprises track 8 word hole 1, T-shaped bolt 2, equipment 3 to be installed and gland nut 4, equipment 3 to be installed has T-shaped mounting hole, T-shaped bolt 2 is positioned at track 8 word hole 1, gland nut 4 is arranged in T-shaped mounting hole and fixes with bolt, it is characterized by: have boss 5 at the root of T-shaped bolt 2 screw rod, boss 5 is with radian, the lower end of gland nut 4 is provided with tightening hoop 6, the anchor ring of tightening hoop 6 has breach 7, when gland nut 4 and T-shaped bolt 2 are fixed, tightening hoop 6 is expanded by boss 5, tightening hoop 6 and track 8 word hole 1 realize interference fit.
Beneficial effect of the present invention is, the technical program only comprises T-shaped bolt 2 and gland nut 4 two critical components, and structure is comparatively simple.In addition, the technical program, when implementing, only needs gland nut 4 to be screwed into, and its rising that automatically can realize T-shaped bolt 2 compresses, and the expansion of tightening hoop 6, also can realize the location to whole erection unit, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the assembling schematic diagram of T-shaped bolt and gland nut;
Fig. 3 is the plan view of T-shaped bolt;
In figure: 1 is track 8 word hole, 2 be T-shaped bolt, 3 be equipment to be installed, 4 for gland nut, 5 is boss, and 6 is tightening hoop, and 7 is breach.
Embodiment
Figure 1 shows that linkage structure schematic diagram, comprise track 8 word hole 1, T-shaped bolt 2, equipment to be installed 3 and gland nut 4.
Track 8 word hole 1 is made up of a series of equidistant 8 word holes and rectangular through slot interval.First by T-shaped bolt 2, equipment to be installed 3 and gland nut 4 preassembly, tightening hoop 6 lower end surface of gland nut 4 is screwed and contacts to T-shaped bolt 2 boss 5, then breach 7 is in the position of Fig. 2.
Equipment 3 to be installed is placed in above track 8 word hole 1, adjusts T-shaped bolt 2 and be placed in 8 word hole grooves, move to the left or to the right in the direction of the arrow, until the tightening hoop 6 of gland nut 4 falls in 8 word holes.Turn clockwise gland nut 4, and T-shaped bolt 2 is fastening rise to 8 groove upper-end surfaces, word hole under threaded engagement effect after.Now, equipment 3 to be installed compresses by gland nut 4, and bottom tightening hoop 6, under the effect of boss 5, with 8 word circular hole interference fit, realizes the location of equipment 3 to be installed and fastening.
This structure characteristic is, will locate, fastening function in one, moulding is simple, compact structure, easy accessibility, requires lower to the mounting interface of equipment.
T-shaped bolt 2, is characterized in that screw rod end symmetric is provided with boss 5.
Gland nut 4, is characterized in that bottom is provided with tightening hoop 6, and tightening hoop 6 circumference is arranged symmetrically with two place's breach 7.
Structure according to claim 1, the internal-and external diameter of tightening hoop 6 is determined jointly by 8 apertures, word hole 1, boss 5 size, with 8 word hole 1 interference fit under boss 5 acts on.
Claims (1)
1. the linkage structure for track 8 word hole, described linkage structure comprises track 8 word hole (1), T-shaped bolt (2), equipment to be installed (3) and gland nut (4), equipment to be installed (3) has T-shaped mounting hole, T-shaped bolt (2) is positioned at track 8 word hole (1), gland nut (4) is arranged in T-shaped mounting hole and fixes with bolt, it is characterized by: have boss (5) at the root of T-shaped bolt (2) screw rod, boss (5) is with radian, the lower end of gland nut (4) is provided with tightening hoop (6), the anchor ring of tightening hoop (6) has breach (7), when gland nut (4) is fixing with T-shaped bolt (2), tightening hoop (6) is expanded by boss (5), tightening hoop (6) and track 8 word hole (1) realize interference fit.
