Description
Technical field
The utility model relates to a kind of boring bar tool, particularly relates to a kind of narrow space Manual drilling instrument.
Background technology
Current electric drill, hand drill are widely used in the boring in industry installation, transformation process.But in actual production process, some use occasion can not use hand drill or electric drill, or equipment Removal can not be carried out boring transformation, as there is huge job safety hidden danger because equipment can not all have a power failure or nearby device is charged in maintenance of electrical equipment or transformation process under specific circumstances; Due to the transformation of enterprise's high and low voltage electric distribution room need to hole on power supply aluminum bus bank time, need the bus bar of whole section to remove and the manpower of at substantial owing to using traditional boring bar tool.
Utility model content
The purpose of this utility model is for above-mentioned Problems existing and deficiency, provides a kind of reasonable in design, can uninterrupted operation and the narrow space Manual drilling instrument taking up room little.
For achieving the above object, the technical scheme taked is:
A kind of narrow space Manual drilling instrument, comprise drilling rod, be set in the rotary stopper sleeve in the middle part of drilling rod, with the base spacing collar being set in drill rod end, on described rotary stopper sleeve, circumference uniform distribution offers multiple screw, in described screw, coupling is provided with and holds out against rotary screw, described base spacing collar be provided with the rolling bearing mated between drilling rod, described drill rod end is provided with and mates spacing ring-shaped step groove with rolling bearing, described base spacing collar sidewall offers at least one locking screw holes, and clamping screw is provided with in described locking screw holes, described base spacing collar sidewall is also fixedly installed base support bar.
Described holding out against on rotary screw is also provided with at least one stop nut.
Described holding out against on rotary screw and base support bar is all arranged with insulation rubber sleeve.
Adopt technique scheme, acquired beneficial effect is:
Boring bar tool of the present utility model, it adopts the location structure of type and new rotation to creep into structure, reasonable in design, structure is simple, and with low cost, and it can achieve aluminium row and not remove the Manual drilling function do not had a power failure, effectively ensure that the normal work of switchgear house, it can be applicable to various different drilling rod size simultaneously, and the model of Reasonable adjustment rolling bearing, meets the demand that different apertures is crept into, expand its function, expand the scope of application, practical, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Fig. 3 be in Fig. 1 A-A to structural representation.
Sequence number in figure: 1 being drilling rod, 2 being rotary stopper sleeve, 3 be base spacing collar, 4 being stop nut for holding out against rotary screw, 5,6 be rolling bearing, 7 be clamping screw, 8 for base support bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
See Fig. 1-Fig. 3, a kind of narrow space Manual drilling of the utility model instrument, comprise drilling rod 1, be set in the rotary stopper sleeve 2 in the middle part of drilling rod 1 and be set in the base spacing collar 3 of drilling rod 1 end, on described rotary stopper sleeve 2, circumference uniform distribution offers multiple screw, in described screw, coupling is provided with and holds out against rotary screw 4, and described holding out against on rotary screw is also provided with at least one stop nut.
Described base spacing collar 3 be provided with the rolling bearing 6 mated between drilling rod 1, described drilling rod 1 end is provided with mates spacing ring-shaped step groove with rolling bearing 6, described base spacing collar 3 sidewall offers at least one locking screw holes, and clamping screw 7 is provided with in described locking screw holes, described base spacing collar 3 sidewall is also fixedly installed base support bar 8.
During for needs uninterrupted operation, hold out against all sheathed insulation rubber sleeve on rotary screw and base support bar described, thus carry out effective dual safety guarantee.
The utility model is in use for the rolling bearing that different environment for use choose reasonable is supporting, fixing rotary stopper sleeve and base spacing collar, external force is applied to base fragrance sleeve, hold out against rotary screw by rotation simultaneously, carry out creeping into work, simple to operate, required working space is little.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
