Abstract
The utility model discloses a screw hole shaft thread connecting structure which comprises a structural member body. The screw hole shaft thread connecting structure is characterized in that a thread joint of the structural member body is provided with a through hole perpendicular to a connecting bolt, and a screw hole shaft in interference fit is arranged in the through hole. The screw hole shaft is provided with an axially vertical threaded hole, and a bolt connecting hole is arranged at the position of the through hole corresponding to the threaded hole. The detachable screw hole shaft is arranged on a structural member so as to replace a threaded hole in an existing structural member, and the goal of replacing a thread can be achieved only by replacing the screw hole shaft when the thread is abraded. In addition, the screw hole shaft is simple in structure, convenient to process and easy to replace, convenience is provided for later-stage maintenance, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of mechanical coupling structure, specifically a kind of hole male thread connecting structure.
Background technique
In existing machinery equipment, adopt the more employing direct auger shell pit on structural member of structural member of scyewed joint, tapped hole is by coordinating with bolt with fixing or mating formation, but for the structural member of wanting frequent dismounting, because bolt will carry out the operation that screws of repetition in tapped hole, the thread profile of tapped hole just is easy to be worn, in case wearing and tearing stripped thread, bolt just can't be tightened, thereby can not effectively connect or fix structural member, the total part all needs again to change like this, has increased maintenance, maintenance cost.
The model utility content
Deficiency for fear of the prior art existence, the utility model provides a kind of hole male thread connecting structure, provide convenient by detachable hole axle being set to substitute the tapped hole in existing structure spare on structural member, safeguarding for later period maintenance, save cost.
The utility model technical solution problem adopts following scheme:
Silk hole male thread connecting structure, comprise the structural member body, its structural feature is, described structural member body scyewed joint place is provided with the through hole perpendicular with attachment bolt, be provided with a hole axle of interference fit in described through hole, described silk hole axle is provided with axially vertical tapped hole, and the through hole corresponding with tapped hole is provided with bolt connecting hole.
The utility model structural feature also is, described silk axle axle head position, hole is provided with groove.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is by arranging detachable hole axle to substitute the tapped hole in existing structure spare on structural member, so just can only need a replacing hole axle just can realize changing the purpose of screw thread in the situation that screw thread is worn, silk hole axle construction is simply easy to process in addition, easily changes; Safeguard for later period maintenance convenient, saving cost is provided.
2, the utility model has groove in axle axle head position, silk hole, can make a hole axle loosening in the situation that a hole axle is rotated in silk hole axle corrosion easily, changes convenient.
Description of drawings
Fig. 1 is the utility model silk hole axle construction schematic diagram.
Fig. 2 is the utility model silk hole male thread connecting structure schematic diagram.
Number in the figure: 1 hole axle, 11 grooves, 12 tapped holes, 2 structural member bodies, 3 bolts.
Technical solutions of the utility model are described further by embodiment below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, a silk hole axle 1 is provided with axially vertical tapped hole 12, and is provided with groove 11 in the axle head position of silk hole axle.As shown in Figure 2, the scyewed joint place of structural member body 2 is provided with through hole, silk hole axle 1 and through hole interference fit, the through hole corresponding with tapped hole 12 is provided with bolt connecting hole, and bolt 3 is threaded with the tapped hole 12 of silk hole axle by attachment hole and realizes the scyewed joint of structural member body or fix.
Claims (2)
1. silk hole male thread connecting structure, comprise the structural member body, it is characterized in that, described structural member body scyewed joint place is provided with the through hole perpendicular with attachment bolt, be provided with a hole axle of interference fit in described through hole, described silk hole axle is provided with axially vertical tapped hole, and the through hole corresponding with tapped hole is provided with bolt connecting hole.
2. according to claim 1 hole male thread connecting structure, is characterized in that, described axle axle head position, hole is provided with groove.
