Description
Technical field
The utility model relates to a kind of adapter sleeve, especially relates to a kind of adapter sleeve that used replace tubes instrument need be connected with electric hand drill in heat exchanger heat-exchanging tube replacing engineering.
Background technology
At present, used replace tubes instrument need be connected with electric hand drill in heat exchanger heat-exchanging tube replacing engineering.Generally adopt general drill chuck to connect, loosening easily, connect insecure.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, is connected firmly, and is convenient to operation, quick-detachable adapter sleeve.
In order to achieve the above object, the technical solution adopted in the utility model is: tapered sleeve left end position is a square opening, right-hand member is a conical bore, be provided with cylindrical hole between two holes, swivel nut is housed in it, be set with spring on the step-like tapered sleeve outer wall, be positioned at tapered sleeve square opening top and have through hole, steel ball is housed in the through hole, the spring outside is set with overcoat, has a circular step to lean steel ball in it, is positioned on the tapered sleeve outer wall of circular step one side to have groove, back-up ring is housed in it, leans on circular step sidewall.
The utility model has the advantages that:
The utility model is simple in structure, is connected firmly, and is easy to operate, practical characteristics.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model tapered sleeve 6 left end positions are square opening 7, and right-hand member is a conical bore 8, be provided with cylindrical hole between two holes, swivel nut 5 is housed in it, is set with spring 4 on step-like tapered sleeve 6 outer walls, be positioned at tapered sleeve 6 square openings 7 tops and have through hole, steel ball 3 is housed in the through hole, spring 4 outsides are set with overcoat 1, have a circular step to lean steel ball 3 in it, are positioned on tapered sleeve 6 outer walls of circular step one side to have groove, back-up ring 2 is housed in it, leans on circular step sidewall.
When the utility model uses, overcoat is moved to the right, steel ball disengaging this moment is not collided with overcoat endoporus step and is connect (crimping), the steel ball play that makes progress, special-purpose replace tubes instrument is plugged in the square hole, at this moment, by the compression spring effect overcoat is resetted, the overcoat stepped ring forging is crimped on the steel ball again, and steel ball moves down and is connected in the specific purpose tool connection handle.
The utility model is as shown below at adapter sleeve, by overcoat, back-up ring, steel ball, spring, swivel nut, tapered sleeve is formed. and overcoat is connected as a single entity by back-up ring and spring and tapered sleeve, steel ball is bumped in the groove of tapered sleeve, swivel nut is packed in the taper hole of tapered sleeve. with overcoat to the pusher time, adapter sleeve is inserted on the replace tubes instrument side handle, unclamp overcoat, steel ball glides in the groove of the side's of being stuck in handle under the effect of spring force, finish and being connected of replace tubes instrument. electric hand drill epicone handle is inserted in the adapter sleeve taper hole, finish and being connected of electric hand drill. during dismounting, in the time of the pusher overcoat, extract the replace tubes instrument. be screwed into swivel nut with a M10 screw rod, the electric hand drill taper shank ejected by the screw rod that screws in.
