Abstract
The invention discloses a connection bolt which comprises a body, wherein a bolt head is arranged at one end of the body, a threaded end is arranged at the other end of the body, an outer thread is machined at the threaded end, a section of polished rod is arranged between the bolt head and the threaded end, the outer diameter of the polished rod is smaller than the outer diameter of the thread of the threaded end, and the diameter of the outer contour of the bolt head is larger than the outer diameter of the thread of the threaded end. The connection bolt is retained after disassembly is completed, therefore, next assembly is facilitated, resources are saved, and waste is avoided. The connection bolt has the advantages of being friendly to the environment, low in cost, easy to manufacture, convenient to use and the like.
Description
Technical field
The present invention relates to a kind of fastening piece, refer to especially a kind of connecting bolt.
Background technique
In mechanical assembling work, usually with bolt, a part is connected on another one part, when a part when another one part is separated separately, unload bolt, just can complete dismantlement work, and dismounting under bolt often throw out without care, need to refill timing, first wife's bolt is difficult to found, causes waste.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcoming in background technique, and a kind of connecting bolt is provided, and this connecting bolt adopts special construction, and after dismounting, this chain connecting bolt and one of them part link together, and there will not be the situation of throwing out without care and can not find.
For addressing the above problem, the present invention takes following technological scheme:
A kind of connecting bolt of the present invention, comprise body, one end of described body is bolt head, the other end is to be processed with externally threaded threaded end, it between described bolt head and threaded end, is one section of polished rod, the external diameter of described polished rod is less than the major diameter of thread of threaded end, and the external frame diameter of described bolt head is greater than the major diameter of thread of threaded end.
A corrective measure of the present invention is: described bolt head is outer-hexagonal head.
Further improvement of the present invention measure is: described bolt head is hexagon socket head.
While using this connecting bolt to connect two parts, can by connecting bolt need to through the through hole of part, at one section of internal diameter near bolt head part, be processed into the circular hole of the major diameter of thread of the threaded end that is slightly less than connecting bolt, by one section of through hole near another one part, be processed into the major diameter of thread that internal diameter is greater than the threaded end of connecting bolt, and the degree of depth is greater than the circular hole of the threaded end length of connecting bolt.During assembling, connecting bolt is slightly exerted oneself through first part, then second part that has a tapped hole is connected to the threaded end of connecting bolt, during dismounting, turn connecting bolt, make the threaded end of connecting bolt be retracted into a larger circular hole space of first part, because the external diameter of the threaded end of connecting bolt is slightly larger than the internal diameter of a less circular hole of first part, therefore can not exit a less circular hole, now second part is removed, but connecting bolt has been stayed on first part.
A kind of connecting bolt of the present invention, because one end of body is bolt head, the other end is to be processed with externally threaded threaded end, it between described bolt head and threaded end, is one section of polished rod, the external diameter of described polished rod is less than the major diameter of thread of threaded end, the external frame diameter of described bolt head is greater than the major diameter of thread of threaded end, therefore, a kind of connecting bolt of the present invention, after dismantlement work completes, has retained connecting bolt, facilitated assembling next time, saved resource, stopped waste, the present invention has environmental protection, low, the easy manufacture of cost, the advantage such as easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of connecting bolt of the present invention, comprise body 1, one end of described body 1 is bolt head 11, the other end is to be processed with externally threaded threaded end 13, between described bolt head 11 and threaded end 13, be one section of polished rod 12, the external diameter of described polished rod 12 is less than the major diameter of thread of threaded end 13, and the external frame diameter of described bolt head 11 is greater than the major diameter of thread of threaded end 13.
Described bolt head 11 is outer-hexagonal heads.
Described bolt head 11 is hexagon socket heads.
While using this connecting bolt to connect upper junction plate 2 and lower connecting plate 3, can be by the internal diameter of the top through hole 21 of upper junction plate 2, be processed into the major diameter of thread of the threaded end 13 that is slightly less than connecting bolt 1, by one section of circular hole 22 of the bottom of upper junction plate 2, be processed into the major diameter of thread that internal diameter is greater than the threaded end 13 of connecting bolt 1, and the degree of depth is greater than the circular hole of threaded end 13 length of connecting bolt 1.During assembling, connecting bolt 1 is slightly exerted oneself through the top through hole 21 of upper junction plate 2, then the lower connecting plate 3 that has tapped hole is connected to the threaded end 13 of connecting bolt 1, during dismounting, turn connecting bolt 1, the threaded end 13 of connecting bolt 1 is retracted in the circular hole 22 of upper junction plate, because the external diameter of the threaded end 13 of connecting bolt 1 is slightly larger than the internal diameter of the one section of circular hole 22 in top of upper junction plate 2, therefore connecting bolt can not exit upper junction plate 2, now lower connecting plate 3 is removed, but connecting bolt 1 has been stayed on upper junction plate 2, there will not be situation about being thrown out without care.
Should be noted that; the foregoing is only the preferred embodiments of the present invention, be not limited to the present embodiment, within the spirit and principles in the present invention all; any modification of doing, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
Claims (3)
1. a connecting bolt, comprise body (1), it is characterized in that: one end of described body (1) is bolt head (11), the other end is to be processed with externally threaded threaded end (13), between described bolt head (11) and threaded end (13), it is one section of polished rod (12), the external diameter of described polished rod (12) is less than the major diameter of thread of threaded end (13), and the external frame diameter of described bolt head (11) is greater than the major diameter of thread of threaded end (13).
2. a kind of connecting bolt according to claim 1, is characterized in that: described bolt head (11) is outer-hexagonal head.
