Description

Full clad type insulation ratchet spanner

Technical field

The utility model is relevant with spanner, more detailed is meant a kind of full clad type insulation ratchet spanner.

Background technology

General spanner is made with metal for asking rigidity intensity preferable, but for having the doubt of electric shock when avoiding using, some spanner can be coated with insulator (as rubber or plastics) in the shank part position.

But, the above-mentioned spanner that has insulation effect in the shank part position, all the other positions there is no any insulating Design, therefore in use, are that the facts that has because of getting an electric shock accidentally takes place.

Therefore, a kind of full clad type Insulation spanner is arranged at present on the market, as shown in Figure 1, it is a ratchet spanner pattern, whole wrench body 1 is coated with insulator, one ratchet sleeve order unit then passes in the 1 formed perforation 2 of this wrench body, and the socket part 3 of this ratchet sleeve order unit one end is piercing in outside perforation 2 one ends, and then expose outside the other end of perforation 2 press section 4 of the ratchet sleeve order unit other end.Because socket part 3 must have on the size precision and keep predetermined rigidity, therefore still be necessary for outer metallic surface, but press section 4 just can be made by the insulation material, via pressing this press section 4, to discharge the location steel ball 5 on the socket part 3, socket part 3 can be emerged on the object of desiring to pull.

Yet, because the full clad type Insulation spanner of this kind, must be before peddling via the Insulation test of an Insulation test machine, its test mode is that full clad type Insulation spanner is imbedded in the multi-conducting steel ball 6, and utilize an insulation body 7 to entangle on this socket part 3 earlier, whether can conduct electricity by these conduction steel ball 6 tests with ratchet sleeve order unit; Though the full clad type Insulation spanner of this kind can form the collar flange 8 of a projection on perforation 2 peripheries of 4 positions, corresponding press section, contact with the ratchet sleeve order of position in perforation 2 is first to avoid conducting electricity steel ball 6, but, because the external diameter of this collar flange 8 is less than the internal diameter of this press section 3, therefore when this press section 3 is the ejection state, can make the ratchet sleeve order unit of the too close position of conduction steel ball 6 in perforation 2 of test usefulness, and then have conduction can't pass through the doubt of test.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of insulation effect preferable full clad type insulation ratchet spanner.

The utility model provides a kind of full clad type insulation ratchet spanner, it includes: a wrench body, its outer surface is coated with an insulating barrier, and this wrench body has a perforation that runs through top, bottom surface, and in the protruding outer shroud protuberance that an insulation is arranged of the keyhole periphery ring of top side location; One ratchet sleeve order unit is placed in the perforation of this wrench body, have a socket part and that stretches out in outside the perforation of wrench body bottom surface and stretch out in the outer press section of wrench body end face perforation, and the external diameter of this press section is less than the internal diameter of this outer shroud protuberance.

Therefore, the full clad type insulation ratchet spanner that the utility model provides, the beneficial effect that has is: can guarantee that the utility model can pass through Insulation test smoothly, and can guarantee operator's security.

The specific embodiment

For making your juror further understanding and approval be arranged, enumerate following preferred embodiment now and cooperate graphic being described as follows feature of the present utility model and characteristics:

See also Fig. 2 and Fig. 3, create a kind of full clad type insulation ratchet spanner 100 that a preferred embodiment is provided for this, it consists predominantly of a wrench body 10 and a ratchet sleeve order unit 20:

See also Fig. 2 and Fig. 3, this wrench body 10 has a service portion 11 and a shank part 12 for operator's gripping, and lays an insulating barrier 13 on the outer surface of this service portion 11 and this shank part 12; Be formed with a perforation 14 that runs through top, bottom surface on this service portion 11, on these service portion 11 end faces, be positioned at the location about place of this perforation 14, convex with the interior ring protuberance 15 of an insulation, and in being somebody's turn to do, encircling on the periphery of protuberance 15 1 preset distances, convex with the outer shroud protuberance 16 of an insulation, i.e. the internal diameter that should interiorly encircle the external diameter of protuberance 15 less than this outer shroud protuberance 16.

See also Fig. 2 and Fig. 3, this ratchet sleeve order unit 20, be set in the perforation 14 of this wrench body 10, and its socket part 21 passes the position outside the perforation 14 of basal surface position, its press section 22 then passes the position outside the perforation 14 of top side location, and be positioned at this ring protuberance 15 the top, and this press section 22 is state of insulation, that is it is made by the insulation material, make and to be positioned at steel ball 23 starts of location, one on this socket part 21 by pushing this press section 22 with control, separate to reach with an object (not shown) of desiring to pull.

Be with, above-mentionedly be each member and the assembling mode introduction thereof that the utility model provides the full clad type of preferred embodiment insulation ratchet spanner 100, then again handling characteristics of the present utility model is described below:

At first, when desiring to test the full clad type insulation of the utility model ratchet spanner 100, be placed on the socket part 21 of this ratchet sleeve order unit 20 with an insulation body 99 earlier, the utility model being placed in one is full of in the testing arrangement of conduction steel ball 98 again, because outer shroud protuberance 16 internal diameters on the utility model wrench body 10 are slightly larger than the external diameter of these ratchet sleeve order unit 20 press sections 22, even if therefore this press section 22 is to be when upspringing state, this outer shroud protuberance 16 still can be with conduction outside steel ball 98 be blocked in, these conduction steel balls 98 are intercepted outside distance ratchet sleeve order unit 20 zone far away.Thus, these conduction steel balls 98 just can't be positioned at perforation 14 ratchet sleeve order unit 20 and contact, also can be because of hypotelorism does not conduct electricity, enable pass is crossed to test and is authenticated, and guarantees that operator does not in the future have the worry of conduction in use.

Above institute takes off, it only is preferred embodiment of the present utility model, it is not scope in order to restriction the utility model embodiment, the equalization that those skilled in the art in the present technique field do according to the utility model changes, and those skilled in that art know change, must belong to the scope that this creation is contained.
