Abstract

The utility model discloses a fall-off prevention holt melting nut which comprises a nut body, a bulged rib, a fixed ring and a guide pine, wherein the nut body is a hollow column; screw threads are arranged on the inner wall of the nut body; the bulged rib is arranged at one end of the nut body or on the outer wall near one end of the nut body; one part of the fixed ring is fixed on the outer wall at the other end of the nut body in a sleeving way; the other part of the fixed ring is provided with an opening penetrating through the fixed ring; and the guide pin is inserted in the opening. When the holt melting nut is in use, the hot melting nut is melted into a holt melting hole column, then the guide pin is pressed downward along the hollow part of the hot melting nut, so that part of the guide pin is hot melted into the hot melting hole column along the opening, and other part of the guide pin is left inside the opening. The hot melting nut axially suffers the resistance from the guide pin so as not to be easily separated from the hot melting hole column as the fixed ring is fixed with the hot melting hole column, part of the guide pin is hot melted into the hot melting hole column, and other part of the guide pin is left inside the opening.

Description

Drop-proof hot melt nut

[technical field]

The utility model relates to a kind of hot melt nut structure, particularly relates to a kind of Drop-proof hot melt nut.

[background technique]

Along with the development of science and technology progress, electronic product more and more widely be applied to family and electronic products such as office occasion, especially notebook computer etc., become necessary tool in people's life especially.

For the assembling of electronic product, can use the hot melt nut as builtup member.See also Fig. 1, Fig. 1 illustrates and is the hot melt nut of prior art and corresponding hot melt hole columniation structure schematic representation thereof.During use, be that described hot melt nut 100 hot melts are gone in the described hot melt hole post 200.Owing to be provided with fin 101 around the described hot melt nut 100, combine with described hot melt hole post 200 internal intervention.

As seen, owing to be provided with fin 101 around the described hot melt nut 100, described hot melt nut 100 is fixing by described hot melt hole post 200 on horizontal plane, and is difficult for rotating.But described hot melt nut 100 is relative to defective tightness with described hot melt hole post 200 in the axial direction, causes described hot melt nut 100 to break away from described hot melt hole post 200 in the axial direction easily.

In view of this, be necessary to develop a kind of Drop-proof hot melt nut in fact, to address the above problem.

[summary of the invention]

Therefore, the purpose of this utility model provides a kind of Drop-proof hot melt nut, avoids the hot melt nut to break away from from the post of hot melt hole.

In order to achieve the above object, the Drop-proof hot melt nut that the utility model provides comprises:

Nut body, it is a hollow cylinder, described nut body inwall has screw thread;

Fin is located on described nut body one end or the close outer wall of an end;

Retaining ring, on the sheathed outer wall that is fixed in the described nut body the other end of a part, another part has the opening that penetrates described retaining ring;

Guide finger is inserted in the described opening.

Optionally, described guide finger is copper guide finger.

Optionally, the face of the close described nut body of described guide finger, the cambered surface that reduces gradually to two-end thickness in the middle of serving as reasons.

Optionally, described opening is four, and the footpath that is uniformly distributed in described retaining ring makes progress.

Optionally, described guide finger should be four mutually.

Optionally, on the described nut body outer wall, between described retaining ring and described fin, also be provided with reinforcement ribs, described reinforcement ribs one side has the breach with described nut body parallel to an axis.

Optionally, described breach is shaped as tri-prism.

Optionally, described hot melt nut is located in the post of hot melt hole, and the external diameter of described retaining ring equals the internal diameter of hot melt hole post.

Compared to prior art, utilize Drop-proof hot melt nut of the present utility model, during use, described hot melt nut hot melt is gone in the post of hot melt hole, push described guide finger downwards along described hot melt nut hollow space again, make described guide finger part advance in the post of described hot melt hole along described opening hot melt, part is stayed in the described opening.Because described retaining ring and described hot melt hole post are fixed, and described guide finger partly incorporates described hot melt hole post, part is stayed in the described opening, and therefore, described hot melt nut is subjected to the resistance of described guide finger on it is axial, be difficult for breaking away from from the post of described hot melt hole.

[embodiment]

Please consult Fig. 2, Fig. 3, Fig. 4 jointly, Fig. 2 illustrates to Drop-proof hot melt nut one preferred embodiment decomposition texture schematic representation of the present utility model, Fig. 3 illustrate to Drop-proof hot melt nut one preferred embodiment package assembly schematic representation of the present utility model, Fig. 4 and illustrates the structural representation of not installing with hot melt hole post into Drop-proof hot melt nut of the present utility model one preferred embodiment.

In order to achieve the above object, the Drop-proof hot melt nut that the utility model provides, in this preferred embodiment, this hot melt nut 19 comprises:

Nut body 10, it is a hollow cylinder, described nut body 10 inwalls have screw thread 11;

Fin 12 is located on described nut body 10 1 ends or the close outer wall of an end;

Retaining ring 13, on the sheathed outer wall that is fixed in described nut body 10 the other ends of a part, another part has the opening 14 that penetrates described retaining ring 13;

Guide finger 15 is inserted in the described opening 14.

Please consult Fig. 5, Fig. 6 again, Fig. 5 illustrates to the Drop-proof hot melt nut one preferred embodiment first mounting structure schematic representation of the present utility model, Fig. 6 illustrate and is the Drop-proof hot melt nut one preferred embodiment second mounting structure schematic representation of the present utility model.

During use, described hot melt nut 19 hot melts are gone in the hot melt hole post 20, push described guide finger 15 downwards along described hot melt nut 19 hollow spaces again, make described guide finger 15 parts advance in the described hot melt hole post 20 along described opening 14 hot melts, part is stayed in the described opening 14.

As seen, because described retaining ring 13 is fixing with described hot melt hole post 20, and described guide finger 15 parts incorporate described hot melt hole post 20, part is stayed in the described opening 14, therefore, described hot melt nut 19 is subjected to the resistance of described guide finger 15 on it is axial, be difficult for breaking away from from described hot melt hole post 20.
