Abstract

The utility model discloses a triangular wrench and an internal triangular thread plug thereof. The structure is as follows: the cross section of the fastening end of the wrench is an external-triangle equilateral triangle; the cross section of the fastening end of the thread plug matched with the wrench is an internal-triangle equilateral triangle; and the thread of the thread plug is an external taper thread or an external pipe thread. The internal triangular thread plug is commonly used for plugging the tail ends of a mechanical oil path, a water path and a gas path with stronger tightness requirement and larger torque force. Under the condition of the same external diameter area, the area of the supporting part of a triangle is obviously larger than that of a quadrangle and a hexagon, and deformability resistance capability is better; and thus, larger torque can be borne during assembling and disassembling. The bearing capability of the supporting part of the utility model can be performed to the maximum extent to furthest ensure that the thread plug can be tightly screwed and removed. Compared with an internal hexagon thread plug and an internal quadrangle thread plug, the triangle keeps more entitative material, so that the triangle can bear larger torque force, and the material and the production process are constant. The utility model is simper to manufacture and is convenient for batch production.

Description

Triangle spanner and interior angular thread plug thereof
Technical field
The utility model belongs to machine tool, is specifically related to thread plug and spanner thereof that a kind of mechanical connection or shutoff are used.
Background technology
Thread plug is the common parts that mechanical connection or shutoff are used, and uses very extensive.The fastening end of thread plug generally is outer-hexagonal, outer four jiaos of types etc. at present.After often requiring mechanical connection or shutoff fastening in technology, its fastening end and sealed parts are same plane, and promptly the thread plug edge crouches in fastened parts, and this moment, interior hexagonal, interior four jiaos form were then adopted in the fastening end of thread plug.The material of thread plug generally is softer materials such as mild steel, copper, improves sealing property with the plastic deformation that makes full use of its screw thread.Contact area is less in other words but softwood matter also causes the sideline of interior hexagonal, interior four corners position easily, uses for a long time or exertin screws and very easily causes deformation effect to reuse, and dismounting is difficulty comparatively also.Particularly be added with fluid sealant when tightening, dismantle as easy as rolling off a log cause interior hexagonal, interior four jiaos damage.
Summary of the invention
The purpose of this utility model is that a kind of interior angular thread plug and spanner thereof that increases torsional forces is provided.
Below in conjunction with accompanying drawing structural principle of the present utility model is described.Triangle spanner and interior angular thread plug thereof, spanner fastening end cross section are outer triangle equilateral triangle, and the thread plug fastening end cross section that is complementary with spanner is interior triangle equilateral triangle, and the screw thread of thread plug adopts outer cone thread or external pipe thread.By Fig. 3 and Fig. 4, Fig. 5 as seen, at triangle body, four jiaos of bodies, three kinds of form thread plugs of hexagon fastening end degree of depth and the inswept rotating ranges of spanner, outside under the situation that the diameter area is identical, the area of triangle body support is obviously greater than four jiaos of bodies and hexagon, non-deformability is also bigger, so no matter assemble and dismantle, can bear bigger moment.
Characteristics of the present utility model and beneficial effect be, the bearing capacity of interior angular thread plug support performs to maximum, guarantees that to greatest extent plug screw twists tightly, tears open following.Internally hexagonal, interior four jiaos of thread plugs mutually, triangle body has kept more solid material, thus can bear bigger torsional forces, and its material and production technology are constant.Make more simply, be convenient to produce in batches.
Description of drawings
Fig. 1 is the utility model triangle spanner structure schematic diagram.
Fig. 2 is an angular thread plug structure schematic diagram in the utility model.
Fig. 3 is interior angular thread jam-pack fixed end generalized section.
Fig. 4 is four jiaos of thread plug fastening end generalized sections.
Fig. 5 is an interior hexagonal thread plug fastening end generalized section.
The specific embodiment
Below by specific embodiment structure of the present utility model is described further.Triangle spanner and interior angular thread plug thereof, its structure is that spanner 1 fastening end cross section is an outer triangle equilateral triangle (as Fig. 1), the thread plug 2 fastening end cross sections that are complementary with spanner 1 are interior triangle equilateral triangle (as Fig. 3), and the screw thread of thread plug adopts outer cone thread or external pipe thread.
Interior angular thread plug generally is used for the shutoff of the shutoff sealing requirements is strong or torsional forces is bigger mechanical oil circuit, water route, gas circuit end.The interior angular thread plug of present embodiment is mainly used in tightens the engine main oil gallery.Triangle spanner and interior angular thread plug thereof are equilateral triangle, length of side 8mm, and material is medium carbon steel (50CRV), to guarantee it stronger rigidity and hardness is arranged.The actual measurement peak torque reaches 50N.m, and yield deformation does not take place the fastening face of thread plug this moment, and dismounting freely, and is time saving and energy saving.
