Abstract
The present invention relates to a kind of variable diameter fastening screws, have tap holder and thread segment, it is characterized in that: thread segment includes a standard thread section and a variable diameter thread segment.The present invention has double thread segment structure, one section is standard thread section, and another section is the variable diameter thread segment for increasing diameter, by the locking of variable diameter thread segment in having run the screw hole that tooth cannot fasten, reliable fastening relationships are formed, provide convenient and reliable selection to maintenance industry.
Description
Technical field:
The invention belongs to fastener areas, in particular to a kind of variable diameter fastening screw, especially a kind of screw thread specification is constant,
Only increase reducer diameter, has both screw tap or squeeze screw tap and directly tighten, suitable for being re-secured when maintenance.
Background technique:
The world the form structure Jun You metric and English specification of existing screw or bolt is convenient to manufacturing industry use.And equipment is tieed up
Repairing is to continue service life and the best approach that economizes on resources, often and emergency best approach, can greatly save to purchase and newly sets
The standby time waited, maintenance of equipment is also an indispensable industry.Maintenance, which is be unable to do without, removes fastener, namely plays fastening and make
Bolt or screw, hereafter referred to collectively as fastening screw；Since these fasteners are different from equipment material, equipment tightens when dispatching from the factory
Gu screw be very in place, it is secondary to dismantle the slight damage for often resulting in screw or screw hole contact portion or expansion, more renew screw
Be easy, but after screw hole is destroyed expansion in equipment, be difficult to lock again new screw, conventional solution be screw hole again
The fastening screw of a big specification is changed in tapping, and the base for causing maintenance screw hole time-consuming and without machining allowance can not reuse, and is taken a lot of work
Duration also needs to configure dedicated tapping equipment etc..This awkward situation of maintenance sites how is solved, pair that the present invention studies is become
As.
Summary of the invention:
The purpose of the present invention is design a kind of variable diameter fastening screw of the screw thread with a segment standard section and a reducer.
The technical scheme is that be achieved: a kind of variable diameter fastening screw, the screw thread with head and fastening hole seat
Section, it is characterized in that: thread segment includes a standard thread section and a variable diameter thread segment.
Variable diameter thread segment one end is provided with tap holder, and variable diameter thread segment is consistent with the screw thread specification of standard thread section.
The diameter of the variable diameter thread segment is big compared with standard thread section, the big 0.10mm of diameter to 0.80mm range.
The present invention has double thread segment structure, and one section is standard thread section, and another section is the variable diameter thread segment for increasing diameter,
By the locking of variable diameter thread segment in having run the screw hole that tooth cannot fasten, tapping is done or squeezes forming reliable fastening relationships,
The other end of the screw of variable diameter is made into the common head of normal screws tooth or internal-external hexagon etc. and uses, and forms reliable fastening relationships, gives
Maintenance industry provides convenient and reliable selection.
Detailed description of the invention:
Below with reference to specific legend, the present invention will be further described:
Fig. 1 variable diameter fastening screw stereoscopic schematic diagram
Fig. 2 variable diameter fastening screw schematic elevation view
Fig. 3 hexagonal variable diameter fastening screw stereoscopic schematic diagram
Wherein
1-head 2-standard thread section 3-variable diameter, 4-tap holder of thread segment
Specific embodiment:
Referring to Figures 1 and 2, variable diameter fastening screw has for the head 1 of tool operation and thread segment, which includes
The standard thread section 2 of one headed 1 and a variable diameter thread segment 3；3 one end of variable diameter thread segment is provided with tap holder 4, variable diameter screw thread
Section 3 is consistent with the screw thread specification of standard thread section 2.Tap holder 4 is by tapping or to squeeze out new hole tooth, is formed reliable tight
Gu relationship.
Further, the diameter of variable diameter thread segment 3 is big compared with standard thread section 2, the big 0.10mm of diameter to 0.80mm range；And become
Depending on the length of diameter section screw thread 2 and standard paragraphs screw thread 3 is as needed.
By taking countersunk head fastening screw as an example, setting can twist this legend in 2 one end of standard thread section by tools such as screwdrivers
Tightly.The head 1 of fastening screw of the present invention is to refer to operating side, the structure having for tool operation both can be processed, such as flat recess, hexagonal
When waiting universal architectures, can also be exactly standard thread section itself, and operating, two nuts be screwed in the one end on head 1, are then led to
It crosses spanner and tightens one nut in outside, the method is fastened with enough power tappings；Then exit two nuts one by one again, it is complete
At fastening task.
It is hexagonal fastening screw referring to Fig. 3, head 1 is hexagonal structure, is tightened using spanner；Six in being equally applicable to
On the bolts such as angle, round end, screw rod, the column of the present invention are belonged to.
