Description
Technical field
The present invention relates to a kind of mechanical structure, more particularly to a kind of connection, fastener and its with applying mechanically spanner structure.
Background technology
Outer-hexagonal hook bolt is connection and a kind of typical machine components in fastener, is widely used in producing and lives
Various aspects.The large complicated mechanical system such as aero-engine, numerical control machining center is all the important application of outer-hexagonal hook bolt
Object, but because such mechanical system structure is complicated, volume is big, when carrying out routinely disassembling inspection to it, often in the presence of some
Angular position is special, human hand is difficult to touch the bolt reached, and the special bolt in these positions is easy to come off and fall during disassembling
Enter inside mechanical system, and be not easy to take out, the bolt fallen into can bring hidden danger even more tight to the normal work of mechanical system
The influence of weight.Usually used outer-hexagonal hook bolt at nut in addition to for dismounting hexagonal prism shape, without it is other can profit
With structure, and it is common can only ensure smoothly to be dismantled with applying mechanically spanner, without possessing clamping, locking function, it is difficult to by bolt
It is subsidiary to take out.For so a kind of more special dismounting situation, lack a kind of more effective connector and its supporting at present
Use spanner structure.
The content of the invention
The purpose of the present invention is that the dismounting situation of taking-up is not easy to for above-mentioned a kind of connector, proposes that one kind can be effective
Prevent the outer-hexagonal hook bolt that comes off and its with spanner structure is applied mechanically, the structure has easy to use, compact, connection reliable
The advantages that.
The technical scheme is that a kind of slip-off preventingconnection and fastening structure, it is characterised in that including outer-hexagonal hook bolt
And spanner, outer-hexagonal hook bolt are radially provided with a through hole at nut, the both ends of through hole carry oblique chamfering;Spanner includes
The structures such as screw rod, handle, lock core, spring, baffle plate, screw;The handle is made up of a studs and two nuts, double end
Stud passes through the through hole of screw rod one end, is formed and is slidably connected with screw rod, the both ends of studs are connected with nut respectively;The spiral shell
The other end of bar is provided with interior hexangle type blind hole, blind round hole is provided with interior hexangle type blind hole sidewall symmetry position, in screw rod bottom
There are semi-cylindrical staged notch and four screwed holes in end face;Lock core includes dome-type end cap and lock pillar, and lock pillar is semicolumn
Shape thin plate, end cap are hemisphere structure;One end of the spring is penetrated in the blind round hole of screw rod, and supports the end face, another
End supports the lock pillar of lock core;The lock core loads in the semi-cylindrical staged notch of screw rod, is formed and is slidably connected between screw rod;
Cover plate is that gabarit is circular, and the thin plate of Intermediate Gray hexangle type through hole, shape of through holes is consistent with hexangle type blind hole in screw rod,
The periphery of hexangle type through hole is provided with four unthreaded holes;The screw is used for connecting screw and cover plate.
The beneficial effects of the invention are as follows:First, its outer-hexagonal hook bolt of slip-off preventingconnection and fastening structure of the invention can be
Carry out adding work realization on the basis of existing bolt, technique is simple, cost is low;2nd, slip-off preventingconnection and fastening structure of the invention
Its spanner is clamped outer-hexagonal hook bolt to be removed by being provided with the lock core of latch functions in screw rod fastening end, effective anti-
Stop the danger that bolt comes off after removal, improve the reliability of dismounting;3rd, slip-off preventingconnection and fastening structure of the invention
Its spanner only relies on Spring driving and can complete to treat the clamping of demounting bolt, simple in construction, and does not need the extra energy
Supply;4th, its spanner of the slip-off preventingconnection and fastening structure of the present invention is in use directly according to the work of common spanner
Mode use, retaining mechanism automatically clamp bolt, improve the operating efficiency of assembly and disassembly;5th, anti-dropout of the invention connects
Connect and be applicable not only to the large complicated mechanical system such as aero-engine, numerical control machining center with fastening structure, apply also for soil
Situations such as building the dismounting of engineering open air high-altitude connector.

Embodiment
Below by specific embodiment and with reference to accompanying drawing, the present invention is described in further detail.
Embodiment one:Illustrate the embodiment of the present invention, embodiment with reference to Fig. 1, Fig. 2, Fig. 4~Figure 10
With apply mechanically spanner 9 include screw rod 2, handle 10, lock core 5, spring 6, baffle plate 7, screw 8;The handle 10 is by a double end spiral shell
Post 3 and two nuts 4 form, and studs 3 passes through the through hole of the one end of screw rod 2, are formed and are slidably connected with screw rod 2, studs 3
Both ends be connected respectively with nut 4;The other end of the screw rod 2 is provided with interior hexangle type blind hole, in interior hexangle type blind hole side wall pair
Claim position to be provided with blind round hole, have semi-cylindrical staged notch and four screwed holes in the bottom end face of screw rod 2;Lock core 5 wraps
Dome-type end cap 11 and lock pillar 12 are included, lock pillar 12 is semi-cylindrical thin plate, and end cap 11 is hemisphere structure;The one of the spring 6
End is penetrated in the blind round hole of screw rod 2, and supports the end face, and the other end supports the lock pillar 12 of lock core 5;The lock core 5 loads spiral shell
In the semi-cylindrical staged notch of bar 2, formed and be slidably connected between screw rod 2;The cover plate 7 is that gabarit is circular, Intermediate Gray
The thin plate of hexangle type through hole, shape of through holes are consistent with hexangle type blind hole in screw rod 2, and four are provided with the periphery of hexangle type through hole
Individual unthreaded hole;The screw 8 is used for connecting screw 2 and cover plate 7.At work, lock core 5 is first for this outer-hexagonal hook bolt spanner 9
Inside the nut press-in screw rod 2 of outer-hexagonal hook bolt 1, when lock core 5 enters in the through hole of outer-hexagonal hook bolt 1, spring 6 will
Lock core 5 ejects, and now lock core 5 clamps outer-hexagonal hook bolt 1, and screw rod 2 normally unscrews outer-hexagonal hook bolt 1, treats outer-hexagonal head spiral shell
When the screw thread of bolt 1 screws out from connected piece completely, spanner 9 is withdrawn, outer-hexagonal hook bolt 1 is taken out with spanner 9.
Embodiment two:Illustrate the embodiment of the present invention, the outer-hexagonal of embodiment with reference to Fig. 1 and Fig. 3
Hook bolt 1 is provided with a through hole at nut, and the both ends of through hole carry oblique chamfering, outer-hexagonal hook bolt 1 is unscrewed using spanner 9
When, outer-hexagonal hook bolt 1 makes the lock core 5 of spanner 9 enter in the nut of outer-hexagonal hook bolt 1 under the guiding of oblique chamfering, this
When, lock core 5 clamps outer-hexagonal hook bolt 1, and the normal work of spanner 9 can take out outer-hexagonal hook bolt 1, slightly be used after taking-up
Power, you can separate spanner 9 and outer-hexagonal hook bolt 1.The process screwed is similar with unscrewing process, will be outer with spanner 9 before screwing
Hexagon-headed bolt 1 clamps, and after outer-hexagonal hook bolt 1 is completely screwed into connected piece, pulls spanner 9, you can separate both.
