Description
Technical field
The present invention relates to adjust bolt technical field, and in particular to a kind of adjusting bolt.
Background technique
In various industrial applications, component is linked together by using fastener.In some applications, between component
There may be gaps.Such as two panels can be separated by clearance area or gap, the part of remaining part can be with indwelling in this
In clearance area or gap.When panel links together, fastener assembly may chuckle in gap and make a sound or slide, by
This generates undesirable noise and provides the connection of loosening.
In addition fastener can be soldered to component, to provide firm connection between the parts.However, welding is labor
It is dynamic and time-intensive, thus increase time and the cost of manufacturing process.Therefore need by gap filling with ensure component it
Between bonding strength.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of adjusting bolt, have between eliminating
Gap and improve component between bonding strength the advantages of.
To achieve the above object, the present invention provides the following technical scheme that a kind of adjusting bolt, including nut support plastics
It covers, is connected with hex nut in the nut support plastic sheath, the nut support plastic sheath is fixedly connected about nut branch
Three stabilizer blades of plastic sheath axial line distribution are supportted, the stabilizer blade is connected with clamping far from the side of nut support plastic sheath
Block, there are gap between the clamping block and stabilizer blade, the hex nut internal screw thread is connected with spacer, the hex nut and
Spacer is disposed as reverse thread, and clamping torque plastic bushing, the clamping torque shape are provided in the spacer
Material bushing is in the inner wall of spacer and squeezes with the inner sidewall of spacer and fixes, and wears between the spacer and hex nut
There is same root threaded rod, one end of the threaded rod is connected with nut, and the circumferential direction of the nut is provided with form friction pattern, described
For nut towards the side integrally connected annulate lamella of threaded rod, the threaded rod is connected with guide pad far from the end face of nut.
By using above-mentioned technical proposal, clamping torque plastic bushing is placed in spacer, then by clamping force
Square type plastics and spacer are socketed on the side of the not set screw thread of threaded rod, and threaded rod is in clamping torque plastic bushing
Stationary state is squeezed, then allows threaded rod to sequentially pass through nut support plastic sheath and hexagonal screw thread, with the rotation of threaded rod, spiral shell
Rasp bar will will drive clamping torque plastic bushing and rotate and then drive spacer rotation, the hand of spiral and hexagonal spiral shell of threaded rod
Female, spacer hand of spiral is on the contrary, therefore threaded rod is continued to towards the movement of the direction of hex nut, and spacer will court
It is mobile away from the direction of hex nut, so that spacer be allowed to be in the gap between threaded rod and external connection object, enhance screw thread
The bonding strength of bar and external connection object.The setting of three stabilizer blades can allow nut support plastic sheath to be socketed on foreign object, clamping
Block can allow nut support plastic sheath to be clamped the inside with foreign object, and the setting of guide pad can facilitate threaded rod to go deep into spacer
It is interior, and the setting of ring flat-plate can be avoided spacer and skid off from one end of threaded rod, can be avoided ring flat-plate and separates with threaded rod.
The present invention is further arranged to: the clamping torque plastic bushing includes cricoid bottom plate, and the one of the bottom plate
Side is connected with multiple arc shape boards, and multiple arc shape board head and the tail are connected with each other, and the cambered surface of the adjacent arc shape board is in
Different planes.
By using above-mentioned technical proposal, the setting of multiple arc shape boards allows clamping torque plastic bushing to have biggish shape
Emptying, therefore the inner space that can not only adapt to spacer squeezes the two more closely, and can adapt to screw thread
Bar, allow threaded rod and clamping torque plastic bushing connection more closely.
The present invention is further arranged to: the spacer includes through spacer through slot, one end of the spacer
It is connected with fixed plate, the spacer integrally connected is in the baffler through slot one end, the side one of the baffler
Body is connected with hex slot.
By using above-mentioned technical proposal, the setting of baffler can be avoided clamping torque plastic bushing because of threaded rod
It drives and is separated with spacer, and the setting of hexagonal grass can facilitate the rotation of spacer, facilitate spacer and hex nut
It is threadedly coupled.
The present invention is further arranged to: the stabilizer blade includes the first card adapter plate and the second card adapter plate being mutually clamped, described
One end of first card adapter plate is connected with corner block, and the side of second card adapter plate towards the first card adapter plate is provided with multiple
For accommodating the triangular groove of corner block.
By using above-mentioned technical proposal, when needing to adjust the length of stabilizer blade, pull the second card adapter plate mobile, this process
Intermediate cam block will be moved along the length direction of the second card adapter plate, and corner block is in different triangular grooves, and stabilizer blade will
Possess different length, therefore the length of adjustable stabilizer blade.
Preferably, the both ends of the spacer are connected with the closed plate for closing spacer both ends open, the interval
Injecting hole is provided in the middle part of part, the clamping torque plastic bushing is made of following component, PBS45-50 parts, polylactide
30-35 parts, 2-5 parts of tossa, 1-2 parts of lubricant, 1-3 parts of toluene di-isocyanate(TDI), 8 parts of base polyurethane prepolymer for use as, phenolic aldehyde tree
12-15 parts of rouge, 4-5 parts of curing agent, 4,4,Methylene two is to 3-4 parts of phenyl diisocyanate and flame retardant polyether polyol 1-2
Part.
Preferably, the curing agent is that 2:1:2 is compounded by toluene -4- sulfuric acid, phosphoric acid and distilled water by weight.
In conclusion the invention has the following advantages:
1, the present invention can eliminate gap and improve the bonding strength between component；
2, in injecting hole after injection molding, there is adherency between clamping torque plastic bushing and the inner sidewall of spacer after molding
Power, and component of the invention is used, there is biggish toughness and deformability, strength can be provided after threaded rod insertion
