Abstract
The utility model discloses a pull out head, including cylindrical pull out head body, the circular shape recess has all been seted up at the both ends of pull out head body, lateral wall an organic whole of two pull out head bodies is provided with external ear, stopper, first lug and second lug, the length of external ear is greater than the length of pull out head body, the spacing groove has been offered along its length direction on the stopper, the radius of spacing groove is the semicircle type, and this utility model has simple structure and characteristics that can reduce cost.
Description
Technical field
The utility model relates to the simple plug of a kind of structure.
Background technique
Plug on gearbox is all formed by Forging Technology manufacture.
At present, the plug on market adds some unnecessary structures because increasing the attractive in appearance of entirety, makes structure too complex, without the cost increasing material, too increases the cost of die sinking.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of plug solved the problem.
For achieving the above object, the utility model provides following technological scheme:
A kind of plug, comprise the plug body of column, the two ends of described plug body all offer circular groove, the outer side wall of described two plug bodies has been wholely set external ear, limiting stopper, the first projection and the second projection, the length of described external ear is greater than the length of plug body, described limiting stopper offers restraining groove along its length, and the radius of described restraining groove is semi-circular.
The utility model is set to further: described groove becomes large by diapire gradually to its radius of notch, and the gradient is 9.6 ° ~ 10.8 °.
The utility model is set to further: radius and the degree of depth of two grooves are consistent.
The utility model is set to further: described first projection is all consistent with the length of plug body with the length of limiting stopper, the length direction two ends of described first projection all with the transition of plug body wedge shape, the both sides of the first projection length direction and plug body arc transition.
The utility model is set to further: described second projection and plug body joint arc transition, described external ear and limiting stopper are the equal arc transition in plug body joint.
The utility model is set to further: the length of described plug body is 49.5mm ~ 50.5mm, and the radius of plug body is 27.6mm ~ 28.8mm, and the length of external ear is 70.2mm ~ 73.2mm, and the diameter of restraining groove is 9mm ~ 12mm.
By adopting technique scheme, primarily of this plug that plug body, external ear, limiting stopper, the first projection and the second projection are formed, structure is simple, reduction cost of material, external ear, limiting stopper, the first projection and the second projection and plug body are wholely set, easily manufactured, and stable connection is firm, and the first projection, the second projection, limiting stopper and external ear are all having arc transition with plug body joint, when forging, avoid producing slight crack.External ear is mainly used in clamping plug body, plug body is connected with other part in gearbox, groove is for the insertion of other part, restraining groove on first projection is used for embedding for pearl or cylindrical object, for when rotating, play the effect pointing out or limit its rotation amplitude, the second segment is used for producing with the part of gearbox being in transmission connection.

Fig. 4 is the enlarged view at A place in Fig. 3 of the utility model plug embodiment.
In figure: 1, plug body; 11, groove; 2, external ear; 3, limiting stopper; 31, restraining groove; 4, the first projection; 5, the second projection.
Embodiment
Referring to figs. 1 through Fig. 4, the utility model plug embodiment is described further.
A kind of plug, comprise the plug body 1 of column, the two ends of described plug body 1 all offer circular groove 11, the outer side wall of described two plug bodies 1 has been wholely set external ear 2, limiting stopper 3, first projection 4 and the second projection 5, the length of described external ear 2 is greater than the length of plug body 1, described limiting stopper 3 offers restraining groove 31 along its length, and the radius of described restraining groove 31 is semi-circular.Unanimously, make it not easily when rotating, generation is rocked for the radius of two grooves 11 and the degree of depth.
Described groove 11 becomes large by diapire gradually to its radius of notch, and the gradient is 9.6 ° ~ 10.8 °.
Described first projection 4 is all consistent with the length of plug body 1 with the length of limiting stopper 3, the length direction two ends of described first projection 4 all with the transition of plug body 1 wedge shape, the both sides of the first projection 4 length direction and plug body 1 arc transition.
Described second projection 5 and plug body 1 joint arc transition, described external ear 2 and limiting stopper 3 are the equal arc transition in plug body 1 joint.
The length of described plug body 1 is 49.5mm ~ 50.5mm, and the radius of plug body 1 is 27.6mm ~ 28.8mm, and the length of external ear 2 is 70.2mm ~ 73.2mm, and the diameter of restraining groove 31 is 9mm ~ 12mm.This size can make the part transmission stability in plug and gearbox higher, improves its working life.
Primarily of this plug that plug body 1, external ear 2, limiting stopper 3, first projection 4 and the second projection 5 are formed, structure is simple, reduction cost of material, external ear 2, limiting stopper 3, first projection 4 and the second projection 5 are wholely set with plug body 1, easily manufactured, and stable connection is firm, first projection 4, second projection 5, limiting stopper 3 and external ear 2 are all having arc transition with plug body 1 joint, when forging, avoid producing slight crack.External ear 2 is mainly used in clamping plug body 1, plug body 1 is connected with other part in gearbox, groove 11 is for the insertion of other part, restraining groove 31 on first projection 4 is for embedding for pearl or cylindrical object, for when rotating, play the effect pointing out or limit its rotation amplitude, the second segment is used for producing with the part of gearbox being in transmission connection.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
