Description
Technical field
The present invention relates to a kind of mechanical fitting field, particularly relate to the device of a kind of quick assembling stud.
Background technology
Currently, the general assembling process of stud is: first screws in two hex nuts at one and tightens, passes through with spanner
Other end is screwed into support by nut, then is pulled down by two nuts with two spanners, is loaded on cover, then by packing ring and nut sleeve
Upper screw rod, fastening nut.Process is loaded down with trivial details, and fruitless labour amount is big, and efficiency is low.There is the special of some assembling studs at present on the market
By instrument, main point of two classes: 1, automatically controlled programming device, the screwing force accurately being controlled screw thread by programming in advance reaches quickly to revolve
Enter, the purpose easily screwed out, this equipment exist expensive, use that environmental requirement is higher, poor universality, accessory kind are many
Defect；2, machinery, more typically utilizes helix of thread lift angle more than screw thread equivalent friction angle, makes screw thread lose self-locking
Principle, should be used for reaching the purpose of rapid-assembling/disassembling Double-ended nut by ingenious for screw structure, this structure comprises leading screw at least by 5
Class part forms, and there is structure complicated, the defects such as core component leading screw is relatively costly.
Summary of the invention
For the deficiencies in the prior art, the present invention provides the device of a kind of quick assembling stud, and the present invention is used for solving
Certainly more easily stud is assemblied in the technical problem of support.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of device of quick assembling stud, including:
Stud, one end of stud is provided with the first external screw thread, the other end be provided with for be bolted in outside support second
External screw thread；
Sleeve, one end of sleeve is the operation structure for wrench operated, and the other end has round platform, and the outer face of described round platform is offered
Have along the axially extended circular channel of sleeve, described round platform offer the interconnection running through circular channel and radially extending,
This interconnection forms two jacks on the sidewall of circular channel；
Round nut, is loaded on described circular channel, has the female thread coordinated with the first external screw thread in this round nut in this round nut,
Offering two waist-shaped holes corresponding with jack on described round nut, the outward opening of each waist-shaped hole is more than inner opening；
Cylindrical pins, described circular pin is connected to two jacks and two waist-shaped holes, and this cylindrical pins and jack interference
Coordinate, this circle pin and waist-shaped hole matched in clearance.
Preferably, described operation structure is to offer the square groove that the square key for external key inserts on sleeve.
Compared to prior art, the beneficial effects of the present invention is: round nut and wrench socket are passed through cylinder by the present invention
The ingenious connection of pin, reaches this pretightning force of spanner nut less than being screwed into that the effect of screw fastening clamp force of support, thus
Decreasing most unnecessary work when making assembling stud to support, efficiency of assembling can be greatly improved, the present invention has
There are simple in construction, the advantage such as easily fabricated, with low cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the cross section view at Figure 1B-B place；
In figure: 1, spanner；11, square key；2, sleeve；21, square groove；3, cylindrical pins；31, waist-shaped hole；4, round nut；5, double end
Bolt；6, support.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
As it is shown in figure 1, the device of a kind of quick assembling stud, including:
Stud 5, one end of stud 5 is provided with the first external screw thread, the other end be provided with for be bolted in outside support 1 the
Two external screw threads；
Sleeve 2, one end of sleeve 2 is the operation structure for spanner 1 operation, and the other end has round platform, the outer face of described round platform
Offer along the axially extended circular channel of sleeve 2, described round platform offers run through circular channel and radially extend horizontal
Passage, this interconnection forms two jacks on the sidewall of circular channel；
Round nut 4, is loaded on described circular channel in this round nut 4, has the interior spiral shell coordinated with the first external screw thread in this round nut 4
Stricture of vagina, described round nut 4 offers two waist-shaped holes 31 corresponding with jack, and the outward opening of each waist-shaped hole 31 is opened in being more than
Mouthful；
Cylindrical pins 3, described circular pin 3 is connected to two jacks and two waist-shaped holes 31, and this cylindrical pins 3 and jack
Interference fit, this circle pin 3 and waist-shaped hole 31 matched in clearance.
As the preferred scheme of one, described operation structure is to offer the square key 11 for external key 1 on sleeve 2 to insert
A square groove 21.
See Fig. 1, the occupation mode of the device of a kind of quick assembling stud, owing to its structure is sleeve 2, straight pin
Nail 3, and round nut 4 be assembled together group device.Sleeve 2 is enclosed within spanner 1, and cylindrical pins 3 is fastened by interference fit
On sleeve 2；Cylindrical pins 3 is matched in clearance with the waist-shaped hole of round nut 4, by waist-shaped hole, screwing force passes to nut 4；
During urgent stud 5, cylindrical pins 3 withstands the bolt head of stud 5, produces end face support reaction F1, and this support reaction causes
Circumferential frictional force f1 stud 5 is screwed in the screwed hole of support 6 together with nut pretightning force F2, now two make a concerted effort (f1,
F2) pretightning force F3 produced equal to support screwed hole；After urgent stud 5, when reversely screwing out round nut 4, due to waist-shaped hole
Existence, cylindrical pins 3 reversion will not be encountered round nut 4, the most only cylindrical pins 3 and then sleeve 2 at once and inverts, it is only necessary to gram
Frictional force f1 taking the generation of end face support reaction just can rotate, and f1 is less than F3, and stud 5 will not be carried over；When cylindrical pins 3
Forward the waist-shaped hole other end to back-outed by drive round nut 4, round nut pretightning force F2 the most only need to be overcome just can be carried by round nut 4
Going out, and F2 is less than F3, stud 5 will not be carried over.So when urgent stud 5, only spanner 1 need to be rotated forward urgent so
The present invention that the most reversely back-outs i.e. can reach the purpose of quick assembling stud 5.
The present invention have simple and compact for structure, simple to operate, efficiency of assembling is high, the feature such as with low cost, it is easy to market pushes away
Extensively.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection domain of the claims in the present invention
Within.
