Description
Technical field
The present invention relates to the bolt and nut fastening piece that assembling part in installing engineering is used.In particular to the mounting fastener that installment inside and outside room needs anti-unrelated person arbitrarily to dismantle.
Background technique
The bolt and nut fastening piece used in installing engineering, the outer-hexagonal bolt and nut of current more employing wrench operated, also have and to adopt hexagon socket head cap screw nut, also the outer-hexagonal bolt and nut of simultaneously available cross or straight screwdriver is had, the outer-hexagonal bolt and nut also having employing sleeve to operate, the operation tool of these mounting types easily obtains, whom causes have way dismounting, this just easily makes the loss of parts of installment inside and outside room and produces property loss, if installment inside and outside room safety protection facility easily split also likely cause occur security incident cause larger damage.
Therefore, to the structure of bolt and nut fastening piece, be necessary to carry out to study the structural system that a kind of scientific and reasonable strick precaution unrelated person is arbitrarily dismantled.Ensure, without the need under changing and needing the associated mounting structure design premises of assembly, to design installation bolt and nut fastening piece and special tool thereof that a kind of anti-unrelated person arbitrarily dismantles while guaranteeing installation quality, installation strength.
Summary of the invention
In order to solve present this bolt and nut fastening piece easily by a difficult problem that unrelated person is arbitrarily dismantled.Take into full account former mounting structure, factor such as construction operability, installation strength etc., continue to use the custom of installation as far as possible, creatively propose the force part of closed spiro rod head as far as possible, the key technology by novelties such as special tool dismounting, produce the utility model patent.
The utility model patent provides a whole set of dismounting-proof bolt nut fastener and special tool structural system thereof.The thinking of invention: first consider that tamper just should be tried one's best the force part of closed spiro rod head, make existing instrument not have Point of Strength; Then peculiar ingenious structure makes bolt head protecting jacket rotate freely, and bolt and nut non rotating; On bolt head, the opening of metal cover plate inserts for special tool, and metal cover plate is movable rotating freely, and the slot bottom bolt head snaps in for the tenon of special tool; Folded by spring two tenons strut by the inclined-plane, slide bar front end of special tool, snap in the slot of bolt head inner bottom part; Handle rotates, and tenon can make the stressed drive bolt head of bolt head bottom slot and screws, thus reaches fastening object; Special tool is made up of tenon, spring, tenon sleeve pipe, slide bar, handle: handle is welded on around tenon ferrule openings; Both ends of the spring is fixed in the hole of tenon band scarf one end, and spring intermediate point is fixed on central bottom in tenon sleeve pipe (just to tenon ferrule openings); Promote slide bar, inclined-plane, slide bar front end and tenon inclined-plane agree with, and strut two tenons, make tenon stretch out tenon sleeve pipe, and handle with sleeve adjustment orientation, in the slot that tenon just can be made to snap in bottom bolt head.
After adopting the new technology of this patent, at present bolt and nut dismantling device on the market comprise adjustable spanner, back-up wrench, Phillips screwdriver, straight screwdriver, sleeve, all kinds of pincers all cannot this novel dismounting-proof bolt nut fastener of dismounting, each base part of installment inside and outside room is not easily arbitrarily dismantled by unrelated person, the generation of property loss or minimizing security incident can be reduced, there is good economic benefit and safety benefit.
Compared with bolt and nut fastening piece conventional at present, novel dismounting-proof bolt nut fastener introduces anti-random dismantling technology reliably breakthroughly, and needs the associated mounting structure of assembly to design without the need to changing again while can not affecting installation quality, installation strength.Therefore the cost of assembly can not be increased.
Installation fastener technology of the present invention practical reliable, draw materials conveniently, make simple, easy to use, respond well, integral installation fastener technology is from looking into the novelty newly learnt and have nationwide.
Because the urbanization degree of present country is more and more higher, the parts of corresponding installment inside and outside room also get more and more, the safety protection facility etc. in the facility in all kinds of guardrail in such as municipal, well lid, gardens, safety in production.At present conventional bolt and nut fastening piece all exists easily by problem that unrelated person is arbitrarily dismantled.Often it was reported that, urban operating mechanism is lost and is caused having people injured, it was reported that safety protection facility is removed without reason and causes industrial accident, cause damage.Thus realize the technological innovation of bolt and nut fastening structure and have very strong current demand.Therefore market of the present invention uses prospect vast.

Embodiment
Dismounting-proof bolt nut fastener package assembly: as shown in Figure 1, 1 is the nut of outward appearance sphere, 9 and 10 parts for there being the needs of mounting hole to install, 2 for there being the bolt head protecting jacket of bottom outlet, the diameter of pad 3 is slightly less than the bottom outlet of bolt head protecting jacket 2, the end of the Thickness Ratio bolt head protecting jacket 2 of pad 3, is slightly large, like this, bolt head protecting jacket 2 can rotate freely but bolt head 5 can not be driven to rotate, 4 is bolt, 5 is hardwired bolt head with bolt, 6, special tool inserting bolt 5 inward turning of 7 and 8 compositions transfer to drive bolt head 5 and bolt 4 to rotate, bolt 4 screws in nut 1, thus reach the fastening object needing the parts 9 and 10 installed.
Bolt head internal structure: as shown in Figure 2,5-1 is bolt head shell, and 5-2 is slot cover plate, and 5-3 is slot, and 5-4 is the entity forming slot, and slot inserts for the tenon of special tool; As shown in Figure 3,5-5 is diaphragm seal, and 5-6 is special tool entrance cover plate, 5-7 is the entrance of the special tool on entrance cover plate, and 5-8 is a tray of entrance cover plate, and entrance cover plate can not be fallen inward, do not fix between entrance cover plate and other position, therefore entrance cover plate can rotate freely.
Special tool structure: as shown in Figure 1, special tool is combined by 6 tenon sleeve pipes, 7 tenons, 8 handles; As shown in Figure 4,7-1 and 7-2 is two tenons, 7-3 is the scarf of two tenons, the two ends of 7-4 spring are fixed in the hole of tenon band scarf one end, spring intermediate point is fixed on central bottom in tenon sleeve pipe 6 (just to tenon ferrule openings), and 6 tenon ferrule openings are used for connecting handle 8-2, and handle 8-1 part is used for rotary manipulation, 8-3 is slide bar handle, and 8-4 is inclined-plane, slide bar front end; Promote slide bar handle 8-3, slide bar front end inclined-plane 8-4 and tenon inclined-plane 7-3 agrees with, strut two tenon 7-1 and 7-2, tenon is made to stretch out tenon sleeve pipe 6, handle with sleeve adjustment orientation, in the slot 5-3 that tenon just can be made to snap in bottom bolt head, handle with sleeve 8-1 part just can drive bolt 4 to enter nut 1, thus reaches fastening object.
