Description
Technical field
The utility model belongs to machinery field, in particular to it is a kind of with interlock function, be connected and fixed reliable and stable screw thread
Improved connection structure.
Background technique
Many connectors are all to be fixedly connected by bolt, nut to lock, for existing bolt and nut,
Its screw thread groove profile for being intermeshed connection and screw pitch be all it is duplicate, such groove profile and the completely the same structure of screw pitch can be with
Meet certain requirement, but there is also larger defect, connective stabilities, poor reliability, during long-time shakes
Easy loose or dislocation fastening failure, connecting-piece structure is easy to damage, and service life is short, and use cost is high, needs frequently to repair replacement, make
Inconvenient, the high failure rate with trouble.
The technical problem to be solved by the present invention is to provide a kind of connective stability high reliablity, vibrations to be also not easy to loosen
Falling off, fastening is failed, connecting-piece structure is hardly damaged, service life is long, use cost is low, without frequently maintenance replacement, user
Just simple, failure rate low strap interlock function, which is threadedly coupled, improves structure.
Utility model content
It fails, even for easily loose or dislocation fastening during the above-mentioned prior art connective stability poor reliability of solution, vibration
Fitting structure fragile, service life are short, use cost is high, need frequently maintenance replacement, using trouble inconvenience, failure rate height etc.
Problem, the utility model adopts the following technical solution:
The utility model provides a kind of threaded connection improvement structure with interlock function, including connected piece, bolt, first
Nut and the second nut, the bolt include pedestal, light bar segment and the first external screw thread, the connected piece be set on bolt and
Lower end surface resists pedestal completely, and first nut includes the first internal screw thread, step supporting section and the second external screw thread, and described second
Nut includes the second internal screw thread and third internal screw thread, and first nut is threadedly coupled by the first internal screw thread with the first external screw thread
Cooperation is tightened on bolt, and the step supporting section bottom of first nut resists connected piece upper surface completely, and described second
Nut by the second internal screw thread is threadedly coupled with the second external screw thread cooperation be tightened on the first nut and pass through third internal screw thread and
First external screw thread is threadedly coupled cooperation while being tightened on bolt, first external screw thread, the first internal screw thread, third internal screw thread
Screw thread groove profile is 60 ° and screw pitch is identical, second external screw thread, the second internal screw thread screw thread groove profile be 55 ° and screw pitch is
The 103%-113% of first external screw thread screw pitch.
The utility model has the beneficial effects that: being threadedly coupled using the screw thread of different groove profiles and different screw pitch, twist
Next generation multiple groups active force and reaction force form interlocking, connect stronger stabilization, and vibration is also not easy loose or dislocation fastening and loses
Effect, connecting-piece structure are hardly damaged, and service life is long, and use cost is low, simple and easy to use without frequently maintenance replacement, therefore
Barrier rate is low.
Detailed description of the invention
Fig. 1 is a kind of the schematic diagram of the section structure of embodiment of the utility model.
Specific embodiment
The preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
Referring to Fig. 1, a kind of threaded connection with interlock function improves structure, including connected piece 1, bolt 2, the first spiral shell
Mother 3 and the second nut 4, the bolt 2 include pedestal 21, light bar segment 22 and the first external screw thread 23, and the connected piece 1 is set in
On bolt 1 and lower end surface resists pedestal 21 completely, and first nut 3 includes the first internal screw thread 31, step supporting section 32 and the
Two external screw threads 33, second nut 4 include the second internal screw thread 41 and third internal screw thread 42, and first nut 3 passes through first
Internal screw thread 31 is threadedly coupled cooperation with the first external screw thread 23 and is tightened on bolt 2,32 bottom of step supporting section of first nut 3
Portion resists 1 upper surface of connected piece completely, and second nut 4 is threadedly coupled by the second internal screw thread 41 with the second external screw thread 33
Cooperation is tightened on the first nut 3 and connect cooperation with the first external screw thread screw thread 23 by third internal screw thread 42 is tightened in spiral shell simultaneously
On bolt 2, first external screw thread 23, the first internal screw thread 31, third internal screw thread 41 screw thread groove profile be 60 ° and screw pitch is identical,
Second external screw thread 33, the second internal screw thread 42 screw thread groove profile be 103%- that 55 ° and screw pitch are 23 screw pitch of the first external screw thread
113%, due to the groove profile and screw pitch difference between screw thread, it will form interlocking between each other, the first nut will form connected piece
One active force is denoted as F10 and reaction force RF10, and the second nut will form an active force to the first nut and be denoted as F21
And a reaction force RF21, bolt will form an active force to connected piece and be denoted as F30 and reaction force RF30, the
One nut will form an active force to bolt and be denoted as F31 and reaction force RF31, and the second nut will form one to bolt
A active force is denoted as F32 and reaction force RF32, connects stronger reliable and stable.
The utility model has the beneficial effects that: being threadedly coupled using the screw thread of different groove profiles and different screw pitch, twist
Next generation multiple groups active force and reaction force form interlocking, connect stronger stabilization, and vibration is also not easy loose or dislocation fastening and loses
Effect, connecting-piece structure are hardly damaged, and service life is long, and use cost is low, simple and easy to use without frequently maintenance replacement, therefore
Barrier rate is low.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
