The specific embodiment
The box spanner sub-assembly that the utility model proposes specifies as follows in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, the box spanner sub-assembly of accordinging to a kind of embodiment of the utility model comprises: sleeve 1 and interior angle spanner 2, sleeve 1 are preferably T jacket tube, and interior angle spanner 2 is preferably the linear spanner, and sleeve 1 removably connects with interior angle spanner 2.Sleeve 1 can carry out dismounting to the exterior angle parts, and interior angle spanner 2 can carry out dismounting to interior angle parts workpiece, thereby makes the sub-assembly of the utility model have the very wide scope of application.
In the sub-assembly of the utility model, sleeve 1 further comprises: socket bar 1-1 and collet head 1-2.
Socket bar 1-1 (be the T type among Fig. 1, but be not limited thereto) accomplishes the effect of extension bar.In the time of need carrying out dismounting to the outer-hexagonal parts, interior angle spanner 2 is dismantled, only use sleeve 1 to get final product, if need high pulling torque, socket bar 1-1 promptly can realize increasing the purpose of the arm of force; When like need the outer-hexagonal parts being carried out dismounting, use interior angle spanner 2, entire sleeve 1 all can be used as the extension bar of interior angle spanner 2, and then realizes increasing the purpose of the arm of force.Such structure has strengthened the operating efficiency of the sub-assembly of the utility model.
Collet head 1-2 is a standard cartridges, also is provided with transmission square hole 3 in it, and transmission square hole 3 also is a standard component.Transmission square hole 3 inwalls are provided with at least one spherical depression 3-1, in this embodiment are 2, and are hemispherical.The top of interior angle spanner 2 is provided with the transmission side's tenon 4 that cooperates with this transmission square hole 3, and this transmission side's tenon also is a standard component.
In the sub-assembly of the utility model, collet head 1-2 can be any hexagon ring sleeve or 12 jiaos of borehole jack tubes of middle disposable type of national standard " GB/T3390.1-nut setter wrench socket " and size.Interior angle spanner 2 can be the inner hexagon spanner of middle disposable type of national standard " GB/T 5356 inner hexagon spanners " and size, also can be interior bihexagon wrench or interior cubic spanner etc.Transmission square hole 3 and transmission side's tenon 4 can be the square tenon and the square hole of disposable type and size in the national standard " GB/T 3390.2-nut setter spanner transmission side's tenon and square hole ", need satisfy the two and can cooperate and get final product.
Further specify the utility model through concrete instance below.
In box spanner sub-assembly as shown in Figure 2:
Socket bar 1-1 is a T type bar, and T type horizontal component is that diameter is the cylindrical bar of 9mm, long h1=200mm, and T type vertically part is the cylindrical bar of diameter 9mm, long h2=250mm.
Collet head 1-2 adopts 12 * 10ALa jacket barrel structure, and (GB/T3309.1 standard opposite side size 12mm, transmission square hole opposite side size e=are the plain edition hexagon ring sleeve of 10mm; Intensity is a level); External diameter
length overall h3=36mm; The partly long h4=13mm of standard cartridges; T=10mm, the long h5=14mm of transmission square hole 3 parts.Transmission square hole 3 adopts C 10 type transmission square hole structures (the C type transmission square hole of GB/T3390.2 standard diagonal-size e=10mm), and its inwall has two hemispherical depression 3-1, is used for cooperating with transmission side's tenon 4.
Interior angle spanner 2 is the linear inner hexagon spanner, and shown in Fig. 3 (a)-Fig. 3 (b), its length overall h6=137mm comprises transmission side's tenon 4 of the long h8=30mm in its top, and hexagonal is to length of side h7=12.7mm.Transmission side's tenon 4 adopts A 10 type transmission side tenon structures (the A type transmission side tenon of GB/T3390.2 standard diagonal-size e1=10mm), the length of side h9=9.5mm of transmission side's tenon 4, and the spheroid of square tenon spring and spring one end cooperates with the depression 3-1 of transmission square hole 3.
Above size is a kind of preferably embodiment of the box spanner sub-assembly of the utility model, not as the restriction to the utility model technical scheme.
The combinations thereof part is when assembling; Interior angle spanner 2 is inserted in the sleeve 1, and the internal diameter of transmission square hole 3 is less than the radical length at transmission side's tenon 4 spring places, and spring compresses; When the spheroid of transmission side's tenon 4 moves to the depression 3-1 place of transmission square hole 3; Spheroid sinks among this depression 3-1, and spring stretches and spheroid is peaked in this depression 3-1, interior angle spanner 2 and sleeve 1 assembled.When needs were dismantled, the application of force was upwards pushed up interior angle spanner 2, the upwards slip of inwall of the spheroid of transmission side's tenon 4 depression 3-1 in edge in depression 3-1; The compression spring; And deviate from from depression 3-1, apply downward power can interior angle spanner 2 be pulled out in sleeve 1 this moment, thereby accomplish the dismounting of sub-assembly.
Above embodiment only is used to explain the utility model; And be not the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be defined by the claims.
