The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
In the utility model, in the situation that not doing contrary explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings as " upper and lower, left and right "; " inside and outside " refers to inside and outside with respect to the profile of each parts itself.
According to an aspect of the present utility model, the utility model provides a kind of pin removal as Figure 1-3, described pin removal comprises pull bar 11, sliding hammer 30 and attaching parts 20, described sliding hammer 30 comprises the through hole 34 for being slidably connected with described pull bar 11, the first end of described attaching parts 20 is connected with the first end of described pull bar 11, described attaching parts 20 second ends have the syndeton being connected for the alignment pin with dismantled, the second end of described pull bar 11 is connected with for the first block 12 with described sliding hammer 30 shocks, described sliding hammer 30 with respect to the glide direction of described pull bar 11 and described alignment pin to extract direction consistent.
During use, the second end of described attaching parts 20 is connected with needing the alignment pin of dismounting by described syndeton, then described sliding hammer 30 slided and described sliding hammer 30 and described the first block 12 are clashed into along described pull bar 11, so just described alignment pin can be removed.Pin pulling device structure that the utility model provides is simple, easy to use, it is laborsaving to dismantle, and small volume can be at operation in narrow space.
Further, described sliding hammer 30 comprises for the second block 32 with described the first block 12 shocks.Arranging of described the second block 32 can make described sliding hammer 30 clash into described the second block 32 more easily, namely increases the area clashing into.
In order to facilitate the application of force, described sliding hammer 30 comprises cylindrical circular Handheld Division 31, and the end relative with the second end of described pull bar 11 of described Handheld Division 31 is provided with first of described the second block 32 of formation and radially extends out structure.Like this when the dismounting that positions pin, hold described Handheld Division 31 and described the second block 32 and described the first block 12 are clashed into, and then make the dismounting that described alignment pin can be easily and fast.
Wherein, the other end of described Handheld Division 31 is provided with second and radially extends out structure, and this second radially extends out structure and form the 3rd block 33.When the dismounting that positions pin, when described sliding hammer 30 is slided along described pull bar 11, arranging of described the 3rd block 33 can prevent tong, once because hand is slipped to described pull bar 11 from described Handheld Division 31 because of carelessness in knockout process, just may cause the problem of described sliding hammer 30 and described pull bar 11 tongs.
Consider the problem that technological design and stress are concentrated, be provided with between chamfering and described the 3rd block 33 and described Handheld Division 31 and be provided with chamfering between described the second block 32 and Handheld Division 31, described chamfering is obtuse angle, is preferably 120 degree-150 degree.
In addition, described pull bar 11 also comprises handle 13, and described handle 13 is arranged on a side of described sliding hammer 30 of deviating from of described the first block 12.Described like this pin removal in use can bimanualness, easy to use.
Certainly, when using described pin removal to position the dismounting of pin, if the frictional force of hand and described handle 13 is excessive not only bad for operation but also may hinder hand, therefore on described handle 13, be provided with for increasing the annular knurl of grasping frictional force.
For Stability Analysis of Structures, design is convenient, and described pull bar 11 is integrally formed and described sliding hammer 30 is integrally formed.
Wherein, the first end of described attaching parts 20 is threaded with the first end of described pull bar 11, and described syndeton is internal thread 41 or external screw thread 42.Preferably, as shown in Figure 5, described attaching parts 20 comprise big column and from the outward extending small column in end of described big column, described big column is threaded with the first end of described pull bar 11, is provided with the external screw thread 42 being connected for the alignment pin with dismantled on described small column.Certain described attaching parts 20 can also be other structures, as shown in Figure 4.During use, can be according to the type of attaching parts 20 described in the type selecting of the alignment pin that will dismantle, for example, when the alignment pin that will dismantle is internal thread, during dismounting, can select attaching parts 20 as shown in Figure 5, when the alignment pin that will dismantle is external screw thread, during dismounting, can select attaching parts 20 as shown in Figure 4.
Preferably, the center line of the center line of described pull bar 11, sliding hammer 30 and described internal thread 41 or external screw thread 42 is located along the same line.Like this, can dismantle faster alignment pin.
Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode.
In addition, between various embodiment of the present utility model, also can be combined, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
