SUMMERY OF THE UTILITY MODEL
To the above-mentioned not enough, the utility model aims to provide a structural design is ingenious, reasonable pine does not take off the pin.
In order to achieve the above purpose, the utility model provides a technical scheme is: the pin comprises a pin head and a pin rod connected with the pin head, wherein a step part, a polished rod part, a tapered reducing part, a clamping ring groove part and a blocking part are sequentially arranged on the pin rod from near to far, the outer diameter of the pin head is larger than that of the step part, the outer diameter of the step part is larger than that of the polished rod part, the diameter of one end, connected with the polished rod part, of the tapered reducing part is larger, the other end of the tapered reducing part is in a gradually reduced shape, the outer diameter of the clamping ring groove part is smaller than that of the other end of the tapered reducing part, and the blocking part is consistent with that of the polished rod part.
As the utility model discloses a preferred scheme, round pin head and pin rod connection structure as an organic whole, firm in connection, structural stability is good.
As a preferable embodiment of the present invention, the length of the step portion is one half of the sum of the lengths of the polished rod portion and the tapered narrowing portion.
As an optimized proposal of the utility model, the periphery outside of the pin head is provided with a circular arc chamfer.
As a preferable embodiment of the present invention, the outer side of the periphery of the blocking portion is provided with an arc chamfer.
The utility model has the advantages that: the utility model discloses a structural design is ingenious, reasonable, pass first at the pin pole, behind the second part, wherein first part is located the step portion, the second part is located smooth rod portion, and this second part can make the circumferential direction action and do the axial reciprocating motion between smooth rod portion and toper reduction portion by first part relatively, in order to satisfy in some special use demands, it is spacing to block the second part through step portion and the snap ring that is located on the snap ring slot portion simultaneously, reach the effect that the pine does not take off.
The present invention will be further explained with reference to the drawings and the embodiments.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
Fig. 2 is a schematic side view of the present invention.
Fig. 3 is a schematic view of the fitting structure of the snap ring groove and the snap ring.
Detailed Description
Referring to fig. 1 and fig. 2, the non-releasing pin provided in this embodiment includes a pin head 1 and a pin rod 2 connected to the pin head 1, where the pin head 1 and the pin rod 2 are an integral connecting structure, and are firmly connected and have good structural stability. Preferably, the outer surface of the anti-loosening pin of the utility model is electroplated with a colored zinc layer, so that the wear resistance and the alkali and acid resistance are effectively improved.
The pin rod 2 is sequentially provided with a step part 21, a polished rod part 22, a tapered reducing part 23, a snap ring groove part 24 and a blocking part 25 from near to far from the pin head 1, wherein the outer diameter of the pin head 1 is larger than that of the step part 21, the outer diameter of the step part 21 is larger than that of the polished rod part 22, the diameter of one end, connected with the polished rod part 22, of the tapered reducing part 23 is larger, and the other end of the tapered reducing part 23 is gradually reduced. This further facilitates the axial reciprocating action of the parts between the polish rod portion 22 and the tapered portion 23. The outer diameter of the snap ring groove portion 24 is smaller than the outer diameter of the other end of the tapered portion 23, and the stopper portion 25 is identical to the outer diameter of the polished rod portion 22.
The outer side of the periphery of the pin head 1 is provided with an arc chamfer and the outer side of the periphery of the blocking part 25 is provided with an arc chamfer, so that the phenomenon that the sharp corner is exposed to hurt people and objects is avoided.
When in use, a first mounting hole matched with the step part 21 is correspondingly arranged on the first part and the second part which need to be connected in advance, and a second mounting hole matched with the polished rod part 22 is arranged on the second part. After the pin rod 2 passes through the first and second mounting holes, the snap ring 3 is clamped on the snap ring groove portion 24, see fig. 3. The whole snap ring 3 is C-shaped, and three supporting legs capable of being pressed on the snap ring groove portion 24 are arranged on the inner ring surface of the snap ring 3. After the knife is assembled, the first part is located at the position of the step part 21, the second part is located at the position of the polished rod part 22, and at this time, since the outer surface of the polished rod part 22 is smooth and has a long length, specifically, the length of the step part 21 is 18mm, the length of the polished rod part 22 is 30mm, and the length of the tapered reduced part 23 is 6 mm. The first and second parts were of uniform thickness, 18mm each. To this end, the second part can perform a circumferential rotation action with respect to the first part and an axial reciprocating action between the polish rod portion 22 and the tapered portion 23 to meet some specific use requirements. If the second part slides to the position of one side of the step part 21 in the axial direction, namely the fixing buckle on the other end of the second part is separated from the clamping groove of the base, at the moment, the first part can drive the second part to move together, namely, the first part is unlocked. When the second part slides to the position of one side of the clamping ring 3 in the axial direction, namely the fixing buckle at the other end of the second part is clamped into the clamping groove of the base, at the moment, the first part cannot move under the limiting action of the second part, and the first part is locked.
Variations and modifications to the above-described embodiments may occur to those skilled in the art, in light of the above teachings and teachings. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation. Like the above-mentioned embodiment of the present invention, other pins obtained by adopting the same or similar structure are all within the protection scope of the present invention.
