Description
Technical field
The present invention relates to a kind of screw assemblies.
Background technique
Screw is most common a kind of fastener in industrial production, during twist screws fixed object, if with
Power crosses stool and be easy to cause the damage for being fixed object.Especially in the assembling process of precision instrument, such as by electronic equipment
When mainboard is fixed on electronic equipment casing, it is likely to cause the damage of mainboard if firmly slightly larger, causes the wave of raw materials for production
Take, reduces industrial efficiency.In addition, if electronic equipment is once accidentally being fallen or being hit, element is highly prone to damage
To cause expendable loss.
Summary of the invention
In view of this, it is necessary to provide a kind of screw assemblies.
A kind of screw assembly, including a threaded post, an end and an elastic component, the threaded post include that a surface is equipped with
The cylinder of screw thread and one be set to described cylinder one end screw terminal, a free end of the screw terminal is equipped with and a spiral shell
The flight of the end cooperation of silk knife.The end is used to keep out the threaded hole that threaded post described in Yu Yiyu matches in assembly
Except.The elastic component includes a first through hole, and one end of the elastic component is socketed in the screw terminal by the first through hole
It above and with screw terminal is fixedly connected, the other end is fixedly connected with the end.And offered in the middle part of the end one with it is described
First through hole and opposite the second through-hole of the flight, for passing through for a screwdriver.
In object fixed using screw assembly of the invention, threaded post during stress precession threaded hole constantly
Downward pulling force is generated to elastic component, so that elastic component is gradually in tensional state and generates upward elastic force, is turned round for offsetting
The partial pressure generated during dynamic screw terminal damages to effectively prevent pressure excessive to being fixed object, and this
The elastic construction of invention also can play a buffer role in, and prevents object from dropping and damages.
Detailed description of the invention
Fig. 1 is the perspective view of screw assembly in an embodiment of the present invention.
Fig. 2 is the explosive view of Fig. 1.
Fig. 3 is the sectional view of screw assembly in a state of use in an embodiment of the present invention.
Main element symbol description
The present invention that the following detailed description will be further explained with reference to the above drawings.
Specific embodiment
Fig. 1 and Fig. 2 is please referred to, the present invention provides a kind of screw assembly 100, can generate upward bullet in use
It is power, as shown in Figure 3 to offset 100 precession of screw assembly, one threaded hole 4() during the partial pressure that generates, prevent pressure
It is excessive to damage to being fixed object.
The screw assembly 100 includes a threaded post 10, an end 20 and an elastic component 30.
The threaded post 10 includes the spiral shell that a surface sets threaded cylinder 101 and is set to described 101 one end of cylinder
Silk head 102, a free end of the screw terminal 102 are equipped with the flight 1021 cooperated with the end of a screwdriver.It is described
The diameter of screw terminal 102 is less than the outer diameter of the cylinder 101, to ensure that the screw terminal 102 can be with 101 precession screw thread of cylinder
Hole 4.The flight 1021 can be " ten " word slot, be also possible to straight slot.
The elastic component 30 includes a first through hole 301, and one end of the elastic component 30 is socketed by the first through hole 301
It is fixedly connected on the screw terminal 102 and with screw terminal 102, the other end is fixedly connected with the end 20.The elastic component
30 outer diameter under natural conditions is less than the outer diameter of the cylinder 101, to ensure that the elastic component 30 can pass through and the cylinder 101
The threaded hole 4 matched.In the present embodiment, the elastic component 30 is a spring, and one end of the elastic component 30 passes through weldering
The mode connect is fixedly connected with the screw terminal 102.
The diameter of the end 20 is greater than the outer diameter of the cylinder 101, for keeping out screw thread described in Yu Yiyu in assembly
Except the threaded hole 4 that column 10 matches, to play the role of engaging to object is fixed.The middle part of the end 20 offers
One second through-hole 201 opposite with the first through hole 301 and the flight 1021, for for a screwdriver by so as to
Twisting operation is carried out to the screw terminal 102.In the present embodiment, the end 20 is made of plastic material, the bullet
The other end of property part 30 is inlaid into the end 20 by plasticity mosaic technology, to be fixedly connected with the end 20.
Referring to Fig. 3, for the sectional view of screw assembly in a state of use in an embodiment of the present invention.Using this hair
When bright screw assembly 100 fixes object, a screwdriver passes through the second through-hole 201 of end 20 and the first of elastic component 30 is led to
Hole 301 carries out twisting operation to screw terminal 102, so that successively precession the first object 200 and the second object to be fixed of threaded post 10
The threaded hole 4 of part 300.In the present embodiment, first object 200 is a pcb board, and second object 300 is a shell
Body.Threaded post 10 constantly generates downward pulling force during stress precession threaded hole 4 to elastic component 30, so that bullet
Property part 30 gradually be in tensional state, elastic component 30 generates upward elastic force because being stretched at this time, for offsetting twist screws head
The partial pressure generated during 102, damages to effectively prevent pressure excessive to by the first object 200.
In addition, screw assembly 100 of the invention can also be applicable in the threaded hole of different length by draw springs 30, and
When being dropped using the fixed object of screw assembly 100 of the present invention, the special elastic construction of screw assembly 100 of the present invention can be risen
To certain buffer function.
Finally it should be noted that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although reference
Preferred embodiment describes the invention in detail, those skilled in the art should understand that, it can be to of the invention
Technical solution is modified or equivalent replacement, without departing from the spirit and scope of the technical solution of the present invention.
