Description
Technical field
The utility model relates to arc section of jurisdiction technique for fixing field, especially a kind of novel arc segment bolt.
Background technique
It is composition machinery and machine that machine components (machine element), which are also known as mechanical organ (machine part),
The single product that can not be decoupled, it is mechanical basic unit.Bolt is a kind of common machine components, is the circle of adapted nut
The threaded fastener of cylindricality.By head and screw rod (having externally threaded cylindrical body) a kind of fastener dimerous, need
Cooperate with nut, for being fastenedly connected two parts for having through-hole.This type of attachment claims to be bolted.As nut from spiral shell
It is screwed off on bolt, and the two parts can be made to separate, therefore being bolted is to belong to be detachably connected.There is turret head, round end,
Square spigot, countersunk head etc..Wherein turret head is most common.General countersunk head, which is used in, requires connection rear surface is smooth do not have protrusion
Place because countersunk head may be screwed in part.Round end can also be screwed into part.The screwing force of square toes can more greatly, still
Size is very big.In addition to meeting the needs locked after installation, there is head porose, bar portion is porose, this some holes can make spiral shell
It is unlikely when bolt is vibrated to loosen.Some bolts do not have the polished rod of screw thread to run business into particular one, and are eel-like figure bolt.This bolt is conducive to by variable force
Connection.There is dedicated high-strength bolt on steel construction, head can be done bigger, and size also changes.In addition there is special use:
T-slot bolt is used, and most in machine tool fixture, shape is special, and both sides of the head will be cut away.Foundation bolt is used for machine and ground
What face was connected and fixed, there are many kinds of shapes.There are also the dedicated stud of welding, one has one, screw thread not have, and can be welded in part
On, the direct nutting in another side.
Double headed arcuate segment bolt is one kind of bolt, and double headed arcuate segment bolt structure in the prior art is more single
One, there is significant limitation bad adaptability.
Summary of the invention
The utility model can adjust the length that extension protrudes into linkage section according to the actual situation, thus to arc section of jurisdiction
The length of bolt entirety is adjusted, and plays the role of increasing practical performance；A kind of novel arc segment bolt is provided.
In order to solve the above technical problems, the structure of the utility model includes bolt body, it is characterised in that: the bolt
Ontology is sequentially connected and is formed by the first bolt, middle bolt fastening and the second bolt, first bolt, the second bolt and centre
Bolt is arc-shaped, and one end of first bolt is equipped with the first external screw thread, and the second described bolt one end is equipped with the second outer spiral shell
Line, nut is threaded on first external screw thread and the second external screw thread, and the side of the nut is equipped with gasket；Described
Middle bolt fastening is made of extension and two linkage sections, and the both ends of the extension are respectively and movably connected to two connections
In section, threaded hole is offered on the outer wall of the linkage section, puller bolt is connected in the threaded hole, described holds out against spiral shell
Bolt passes through threaded hole and is connected with extension.
It is provided in groove further, opening up fluted, described threaded hole on the outer wall of the linkage section, it is described
Puller bolt is connected on linkage section in the form of being embedded in groove.
Further: the other end of first bolt is equipped with the first engaging lug, and the second externally threaded other end is set
There is the second engaging lug, first bolt and the second bolt pass through the first engaging lug respectively and the second engaging lug is connect with two
Duan Xianglian.
Further: the edge of first engaging lug and the second engaging lug is arc-shaped.
After adopting the above structure, the utility model can adjust the length that extension protrudes into linkage section according to the actual situation
Degree plays the role of increasing practical performance so that the length of arc segment bolt entirety be adjusted；And the design is also
Have the advantages that structure is simple, easily fabricated and practical and efficient.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A kind of novel arc segment bolt as shown in Figure 1, including bolt body 1, the bolt body 1 are by the first spiral shell
Bolt 2, middle bolt fastening and the second bolt 3 are sequentially connected and are formed, and first bolt 2, the second bolt 3 and middle bolt fastening are in arc
Shape, one end of first bolt 2 are equipped with the first external screw thread 5, and described 3 one end of the second bolt is equipped with the second external screw thread 6, described
Nut 7 is threaded on first external screw thread 5 and the second external screw thread 6, the side of the nut 7 is equipped with gasket 8；In described
Between bolt be made of extension 4-2 and two linkage section 4-1, the both ends of the extension 4-2 are respectively and movably connected to
In two linkage section 4-1, threaded hole is offered on the outer wall of the linkage section 4-1, is connected in the threaded hole and holds out against spiral shell
Bolt 4-3, the puller bolt 4-3 pass through threaded hole and are connected with extension 4-2.The utility model can be adjusted according to the actual situation
