Abstract
The invention belongs to parts connection field and particularly relates to a connecting pin which is convenient to install and dismantle, and an anti-rotating connecting device applying the same. The connecting pin comprises a pin body; a clump weight is arranged below the center of the end face of the pin body to enable the pin body to rotate; and after the pin body is installed, the clump weight enables the opening of key slots to be in a vertically outward state for the convenience of installing or dismantling a key. The anti-rotating connecting device comprises at least two bases provided with lifting lugs; connecting holes are arranged on the lifting lugs; the connecting pin runs through the connecting holes; the pin body and the lifting lugs enable the key to be occluded between the pin body and the lifting lugs; the key is partially occluded in the key slots a on the lifting plugs and is partially occluded in the key slots b on the pin body; and in such a way, the rotation of the key during the transportation process is avoided and therefore the risk that the pin body falls off is reduced.
Description
Technical field
The invention belongs to a kind of parts connection area, especially relates to a kind of installation or removal connecting pin and use the anti-rotation connection set of this connecting pin easily.
Background technique
In existing technology, connecting pin commonly used carries out the connection of parts, is connected firmly for making parts and connecting pin, also will be between them load key, and then keyway need be set on connecting pin.In the as installed process, because installing space is narrow and small, after connecting pin is packed into, keyway uncertain towards very, and then make the installation or removal difficulty of key.
When multi-part connects, when particularly two parts need connect, often be connected with hanger above that; With the attachment hole of shank on the hanger, through key two parts are linked together, and key all is arranged on the shank; In concrete handling process; Regular meeting is because of the rotation of parts self, and the possibility that exists shank to deviate from very easily causes the damage of personnel or article.
The innovation and creation content
The problem that the invention will solve provides the anti-easily connecting pin and use the anti-rotation connection set of this connecting pin of migrating of a kind of installation or removal.
For solving the problems of the technologies described above, the technological scheme that the invention is adopted is:
A kind of connecting pin comprises shank in the formation, be provided with the balancing weight that makes the shank rotation in the below at its end face center.
Above-mentioned connecting pin, the both ends of the surface of this shank are provided with balancing weight.
Above-mentioned connecting pin in the edge of shank end face, is provided with keyway b along the shank bearing of trend.
Above-mentioned connecting pin, the both ends of the surface of this shank are provided with keyway b.
A kind of anti-rotation connection set of using above-mentioned connecting pin; The pedestal that comprises at least two band hangers in the formation; This hanger is provided with attachment hole, runs through this attachment hole above-mentioned connecting pin is set, and this shank and hanger are gnawed key and closed in above-mentioned anti-rotation connection set between it; This key is partly gnawed the keyway a that closes on hanger, and part is gnawed the keyway b that closes on shank.
Above-mentioned anti-rotation connection set is characterized in that, this hanger is trapezoidal.
Above-mentioned anti-rotation connection set is characterized in that, the matrix of this pedestal is provided with and the fixing fixed hole of parts to be connected.
Above-mentioned anti-rotation connection set is characterized in that, this fixed hole is 4.
In the invention, be provided with the balancing weight that makes the shank rotation in the below at shank end face center, after this balancing weight makes the shank installation, make the gap of keyway be in vertical state outwardly, be convenient to the installation or removal of key.In addition; This shank and hanger are gnawed key and are closed between it, and this key is partly gnawed the keyway a that closes on hanger, and part is gnawed the keyway b that closes on shank; So just make parts in handling process; Avoid self rotating, and then the risk reduction that shank is deviate from, also be convenient to whole Unit Installation or dismounting.

Embodiment
Referring to Fig. 1, Fig. 2, the invention comprises shank 1 in constituting, and this shank 1 end face is circular; Edge in shank 1 end face; Be provided with keyway 11 along the shank bearing of trend, the below at this shank 1 end face center is provided with balancing weight 12, after balancing weight 12 makes the shank installation; Make the gap of keyway 11 be in vertical state outwardly, be convenient to the installation or removal of key.Keyway 11, balancing weight 12 are provided with in two end faces of shank respectively.The height h of keyway 11 can be 1/3 of shank 1 overall height H.
Referring to Fig. 3, Fig. 4; The pedestal a or the b 1,2 that comprise at least two band hanger a or b 13,23 during the invention constitutes; This hanger is provided with attachment hole a or b 14,24, runs through this attachment hole and is provided with shank 3, and this shank and hanger are gnawed key 4 and closed between it; This key is partly gnawed the keyway a 25 that closes on hanger, and part is gnawed the keyway b 32 that closes on shank.
In order to make at narrow space; Can efficiently parts to be carried be linked together, be provided with the balancing weight 31 that makes the shank rotation in the below at these shank 3 end face centers, after balancing weight makes the shank installation; Make the gap of keyway be in vertical state outwardly, be convenient to the installation or removal of key.
On the matrix a or b 11,21 of pedestal, be provided with fixed hole a or b 12,22, use bolt etc. can make hanger and treat that handling article is fixed together.
Referring to Fig. 5, the installation process of the invention:
After parts to be carried and hanger are fixing; Make the attachment hole on the hanger corresponding, the user can with this shank through this attachment hole, shank is under the effect of balancing weight then; Rotate motion; Make the gap of keyway be in vertical state outwardly, the adaptive key of packing into can be accomplished the connection of parts.
