Abstract
The utility model discloses an assembling tool for an O-shaped ring. The assembling tool comprises a guiding portion, an expansion portion, a guide sleeve and an inner guide rod, wherein the guiding portion is of a cylindrical shape, and the external diameter of the guiding portion is smaller than the internal diameter of the O-shaped ring; the expansion portion is of a cone frustum shape, the external diameter of the small end of the cone frustum is the same as the external diameter of the guiding portion, and the external diameter of the large end of the cone frustum is larger than the internal diameter of the O-shaped ring and larger than the external diameter of a jumping pipe; the external diameter of the guide sleeve is not larger than the external diameter of the large end of the cone frustum, the internal diameter of the guide sleeve is larger than the external diameter of the jumping pipe, and the external diameter of the inner guide rod is smaller than the internal diameter of the jumping pipe. The assembling tool for the O-shaped ring is simple in structure, low in cost, convenient and reliable to operate and capable of effectively reducing the risk that the O-shaped ring is damaged in installation, improves assembling quality of a product, and avoids the defect of component abandonment.
Description
Technical field
The utility model mechanical frock relates to technical field, relates in particular to a kind of O shape circle assembly tool.
Background technology
On the jumping pipe of motorcar air conditioner, need to install O shape circle, play the effect that allows external drier seal.Existing assembling process is all gone to scratch with finger nail or with instruments such as screwdrivers (bottle opener), is gone to expand O shape and enclose and be assembled on jumping pipe.
While directly packing jumping pipe into hand extruding O shape snare, due to firmly uneven, be easy to cause the breakage of O shape circle, thereby cause sealing property bad, have the hidden danger of desiccant leakage.
With instruments such as screwdrivers (bottle opener), go to expand O shape and enclose to be assembled to and jumped pipe when upper, because the head of such instrument is all sharp, easily causes too O shape circle damaged, thereby cause sealing property bad, have the hidden danger of desiccant leakage.
Therefore, those skilled in the art is devoted to develop a kind of O shape circle assembly tool, has easy-to-usely, does not damage the advantage of O shape circle.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of simple in structure, easy-to-use O shape circle assembly tool.
For achieving the above object, the utility model provides a kind of O shape circle assembly tool, and described O shape circle assembly tool comprises guide portion, enlarged portion, guide pin bushing and inner guide; Described guide portion is cylindrical, and external diameter is less than described O shape circle internal diameter; Described enlarged portion is a truncated cone, and the small end external diameter of the described frustum of a cone is identical with the external diameter of described guide portion, and the large end external diameter of the described frustum of a cone is greater than O shape circle internal diameter and is also greater than jumping pipe external diameter; The external diameter of described guide pin bushing is not more than the large end external diameter of the described frustum of a cone, and the internal diameter of described guide pin bushing is greater than the external diameter of described jumping pipe, and the external diameter of described inner guide is less than the internal diameter of described jumping pipe.
Preferably, described guide portion, described enlarged portion, described guide pin bushing and described inner guide are structure as a whole.
Preferably, described guide pin bushing is coaxial setting with described inner guide.
The beneficial effects of the utility model are:
O shape circle assembly tool of the present utility model, simple in structure, cost is low, and convenient and reliable operation can effectively reduce the O shape circle risk of breakage when mounted, has improved the quality of Product Assembly, the defect of having avoided part to scrap.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model one embodiment.
Fig. 2 is the broken section structural representation that the utility model one embodiment is used state.
Fig. 3 is that Fig. 2 removes the left view of jumping after pipe.
Fig. 4 is that Fig. 2 removes the right view of jumping after pipe.
The specific embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, O shape circle assembly tool of the present utility model one specific embodiment, comprises guide portion 1, enlarged portion 2, guide pin bushing 31 and inner guide 32.
In the present embodiment, guide portion 1, enlarged portion 2, guide pin bushing 31 and inner guide 32 are structure as a whole.Certainly, in other embodiments, also can Split type structure and be fixedly connected with by screw thread etc.
Enlarged portion 2 is a truncated cone.The small end external diameter of the frustum of a cone is identical with the external diameter of guide portion 1, also can be chosen as
, the large end external diameter of the frustum of a cone is greater than O shape circle internal diameter, is also greater than and jumps pipe external diameter, for example, can be chosen as
.The cone angle of the frustum of a cone can be selected 20 °, or other angles.
The external diameter of guide pin bushing 31 is not more than the large end external diameter of the frustum of a cone, can be identical.The internal diameter of guide pin bushing 31 is greater than the external diameter of jumping pipe 4, for example, can be chosen as
.
For example, in the embodiment that a plurality of O shape circles need to be installed (needing to install 2 or 3), the internal diameter of guide pin bushing 31 is also greater than and is contained in the external diameter of jumping first O shape circle on pipe.
The external diameter of inner guide 32 is less than the internal diameter of jumping pipe, for example, can be chosen as
.In the present embodiment, guide pin bushing 31 is coaxial setting with inner guide 32.
The internal diameter of guide pin bushing 31
external diameter with inner guide 32
it is the location of jumping pipe 4 for coordinating.
During use, first O shape circle is inserted in from guide portion 1, then the guide pin bushing 31 of the O shape circle instrument other end is inserted into and is jumped in pipe 4 with inner guide 32, finally O shape circle is smeared to enlarged portion 2 along guide portion 1, because O shape is enclosed as quality of rubber materials has high dilatancy and shrinkage, at enlarged portion 2 places, O shape is enclosed swell slightly, can be pushed into and jump in pipe 4, complete O shape circle and the assembling of jumping pipe 4.
O shape circle assembly tool of the present utility model, simple in structure, cost is low, and convenient and reliable operation can effectively reduce the O shape circle risk of breakage when mounted, has improved the quality of Product Assembly, the defect of having avoided part to scrap.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
