Abstract
A plastic spring screw mainly consists of a screw bolt (1) and a spring (2), and is characterized in that the spring (2) is sleeved on the screw bolt (1), the screw bolt (1) is made of materials which are formed by PA66 plastic materials via special boiling process and other special technical processes, an umbrella-shaped capped head (11) is formed at the head of the screw bolt (1), a cylindrical rod (12) is formed in the middle of the screw bolt (1), a press head (13) is formed at the tail of the screw bolt (1), the umbrella-shaped capped head (11) is provided with compression grooves (14) which provide compressing space for realizing compression, the diameter of the cylindrical rod (12) is slightly smaller than that of the umbrella-shaped capped head (11) and is smaller than that of the press head (13) simultaneously, the inner diameter of the spring (2) is slightly larger than the inner diameter of the cylindrical rod (12) and is slightly smaller than diameters of the umbrella-shaped capped head (11) and the press head (3), the spring (2) can be sleeved by compressing the umbrella-shaped capped head (11), and after the umbrella-shaped capped head (11) is released and reset, the spring (2) is sleeved on the cylindrical rod (2) of the screw bolt (1).
Description
Technical field
The utility model relates to a kind of screw, and especially a kind of radiator that is applicable to computer and mainboard be the plastic spring screw of usefulness fixedly.
Background technique
Continuous progress along with science and technology, computer has obtained using widely, fixing of the mainboard of computer and radiator, adopt screw to carry out fastening mostly with screw thread, the time need adopt screw-driver to operate to realize tightening or pine is unloaded in operation, and prerequisite is to need screw thread on the screw rod of screw, also need the screw thread that cooperates with it in the mainboard hole that screw pierces into, need preposition screw thread manufacturing procedure, overall cost height is when screw is fastening, all lean on operator's hand to operate, then there is non-uniform phenomenon mostly in the fastening force in each screw fastening point, does not then reach people's assembly technology requirement, can not satisfy people's needs.
Summary of the invention
The purpose of this utility model is a kind of addressing the above problem of development, and is simple in structure, uses easy to operate, the overall fixing plastic spring screw of usefulness of radiator that is applicable to computer that cost is low and mainboard.
The utility model is achieved through the following technical solutions:
The utility model mainly is made up of screw and spring, it is characterized in that: spring housing is on screw, wherein, it is to be formed through special technology to boil water and other special technique processes by P A 66 plastic materials that screw adopts material, the screw head forms the umbrella discount, the umbrella discount, the umbrella discount has compression groove, compression groove provides compression volume to realize compression, compression groove can be that the disjunctor groove structure can be the split groove structure also, and part forms cylindrical bar in the screw, and the screw afterbody forms head, head can be designed to multiple shape, as ellipse, circular, hexagonal capitiform etc., the umbrella discount is compressible, and the cylindrical bar diameter is slightly less than umbrella discount diameter, simultaneously less than the head diameter, the spring inner diameter is slightly larger than the cylindrical bar diameter, is slightly less than umbrella discount diameter and head diameter, and compression umbrella discount can overlap upper spring, the umbrella discount discharges to open and resets, and spring promptly is enclosed within on the cylindrical bar.
In use, the hole of radiator and mainboard is directly passed in umbrella discount compression after diameter diminishes, length of spring compressed, and the umbrella discount exposes to discharge to open behind the hole of mainboard and resets, and is stuck in the place, hole, and spring stress can tighten radiator and mainboard, reaches purpose of design.
This reality is novel to have following advantage:
1, via enforcement of the present utility model, simple in structure, cost is low, and is easy to operate, energy-conserving and environment-protective.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model embodiment one a structural representation.
Fig. 2 is the structural representation of sectional view of the utility model embodiment one screw.
Fig. 3 is the utility model embodiment two a structural representation.
Fig. 4 is the structural representation of sectional view of the utility model embodiment two screw.
Among the figure, 1 screw, 11 umbrella discounts, 12 cylindrical bars, 13 heads, 14 compression grooves, 2 springs
Embodiment
The utility model shown in the figure mainly is made up of screw (1) and spring (2), it is characterized in that: spring (2) is enclosed within on the screw (1), wherein, it is to be formed through special technology to boil water and other special technique processes by P A 66 plastic materials that screw (1) adopts material, screw (1) head forms umbrella discount (11), part forms cylindrical bar (12) in the screw (1), screw (1) afterbody forms head (13), umbrella discount (11) has compression groove (14), compression groove (14) provides compression volume to realize compression, cylindrical bar (12) diameter is slightly less than umbrella discount (11) diameter, simultaneously less than head (13) diameter, spring (2) inner diameter is slightly larger than cylindrical bar (12) diameter, be slightly less than umbrella discount (11) diameter and head (13) diameter, compression umbrella discount (11) can overlap upper spring (2), and umbrella discount (11) discharges to open and resets, and spring (2) promptly is enclosed within on the cylindrical bar (12) of screw (1).
In Fig. 1 and Fig. 2, the compression groove (14) of umbrella discount (11) forms the disjunctor groove structure.
In Fig. 3 and Fig. 4, the compression groove (14) of umbrella discount (11) forms the split groove structure.
The utility model is simple in structure, and is easy to operate, and cost is low, reliable performance, and the radiator and the mainboard that are widely used in computer are fixedly used the field.
Claims (2)
1, plastic spring screw mainly is made up of screw (1) and spring (2), and it is characterized in that: spring (2) is enclosed within on the screw (1).
2, plastic spring screw according to claim 1, it is characterized in that described screw (1) head forms umbrella discount (11), part forms cylindrical bar (12) in the screw (1), screw (1) afterbody forms head (13), umbrella discount (11) has compression groove (14), cylindrical bar (12) diameter is slightly less than umbrella discount (11) diameter, simultaneously less than head (13) diameter, spring (2) inner diameter is slightly larger than cylindrical bar (12) diameter, is slightly less than umbrella discount (11) diameter and head (13) diameter.
