Abstract
The invention discloses a kind of link, comprise bolt and be socketed in the lining on the screw rod of described bolt, at least one end face of described lining is oval.The invention solves lining and the segregative problem of bolt in prior art, by ellipse is arranged in the one or both ends of the lining be socketed on bolt, make its shorter diameter slightly larger than or equal the diameter of screw rod, carry out spacing by the screw thread of screw rod underpart to elliptoid bush end face, avoid being separated of lining and bolt, be convenient to the installation of link, improve installation efficiency.
Description
Technical field
The present invention relates to a kind of link, belong to Machining Technology field.
Background technique
Link is widely used in connection between the material of different qualities and application.In order to make the connection better effects if of link, usually on the screw rod of link, be set with lining, and this lining is normally arranged on screw rod with regard to supporting before link dispatches from the factory, so that more convenient when the later stage uses.But, overlapping to enable lining installs on screw rod, usually the internal diameter of lining is designed to consistent with screw flight portion width, and lining is directly sleeved on screw rod, this mounting type in the transportation process of link, owing to jolting, rocking, be easy to lining and screw rod are separated, cause link in use, needing to reselect suitable lining, to carry out cooperation complete, causes installation efficiency low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of link, effectively can avoid being separated of sleeve pipe and bolt, be convenient to the installation of link, improve installation efficiency.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of link, comprises bolt and is socketed in the lining on the screw rod of described bolt, and at least one end face of described lining is oval.
Aforesaid a kind of link, is characterized in that: the upper-end surface of described lining is for oval.
Aforesaid a kind of link, is characterized in that: the lower end surface of described lining is for oval.
Aforesaid a kind of link, is characterized in that: the shorter diameter of the oval end face of described lining is identical with the diameter of described screw rod.
The invention has the beneficial effects as follows: by ellipse is arranged in the one or both ends of the lining be socketed on bolt, make its shorter diameter slightly larger than or equal the diameter of screw rod, carry out spacing by the screw thread of screw rod underpart to elliptoid bush end face, avoid being separated of lining and bolt, be convenient to the installation of link, improve installation efficiency.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of link of the present invention;
Fig. 2 is the plan view of the lining of a kind of link of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of link, the lining 2 comprising bolt 1 and be socketed on the screw rod 11 of described bolt 1, when lining 2 cover of ring opening is received after on screw rod 11, make its at least one end face for oval by the mode of extruding, the shorter diameter of the oval end face of lining 2 is identical with the diameter of described screw rod 11, or slightly larger than the diameter of screw rod 11, Extreme breadth due to the screw section of screw rod 11 is greater than the shorter diameter of the oval end face of lining 2, therefore, carry out spacing by the screw thread of screw rod 11 underpart to elliptoid bush end face, avoid being separated of lining 2 and bolt 1, be convenient to the installation of link, improve installation efficiency.
Through actual tests, the upper-end surface of lining 2 or lower end surface are oval, can avoid being separated of lining 2 and bolt 1, be convenient to the installation of link, improve installation efficiency.
More than show and describe basic principle of the present invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is by appending claims and equivalent circle thereof.
Claims (3)
1. a link, comprise bolt (1) and be socketed in the lining (2) on the screw rod (11) of described bolt (1), it is characterized in that: at least one end face of described lining (2) is for oval, the shorter diameter of the oval end face of lining (2) is identical with the diameter of described screw rod (11), or slightly larger than the diameter of screw rod (11), Extreme breadth due to the screw section of screw rod (11) is greater than the shorter diameter of the oval end face of lining (2), therefore, carry out spacing by the screw thread of screw rod (11) underpart to elliptoid bush end face.
2. a kind of link according to claim 1, is characterized in that: the upper-end surface of described lining (2) is for oval.
3. a kind of link according to claim 1 and 2, is characterized in that: the lower end surface of described lining (2) is for oval.
