Abstract

The utility model relates to the technical field of fasteners and discloses a novel screw comprising a screw cap and screw threads; the screw threads include an internal thread and an external thread; a layer of elastic body is established between the internal thread and the external thread; and the elastic body is completely embedded in a gap between a thread crest and a thread root. The problem of looseness caused by the gap between the internal thread and the external thread is solved foundationally, and the novel screw is low in processing cost and high in efficiency.

Description

A kind of novel screw

Technical field

The utility model relates to the technical field of fastening piece.

Background technique

Screw is usually used in every field such as industry, science and technology, daily life, in use usually can be because of external force factors such as the matching gap of thread itself or vibrations, and cause screw after assembling, to produce getting loose even come off, cause some unnecessary loss.Screw generally comprises nut and screw thread, and the general material that constitutes of nut and screw thread is a metallic material.Screw thread is not to seal very much with the object contact that contacts, and can come loose sometimes.

And, cause cost waste, work efficiency not high at present to the traditional anti-loose structure design more complicated of screw.Tradition is locking, sealed screw is on screw, to wear locking, the black box of specialty mostly; The general materials such as increasing elastic washer, serrated lock washer, rubber washer that adopts; Or the screw terminal lower plane carried out particular design, and being designed to radiate flexuose to screw terminal sometimes, purpose is to increase the surface friction drag on screw head and assembly parts surface; Reach anti-loosing effect; And these modes can not fundamentally solve the locking problem that is produced by the thread matching gap, and cause cost to increase, and purchase locking/black box, tailor-made special header shaping die etc., complex proceduresization such as other.

The model utility content

The utility model purpose aims to provide a kind of novel screw, has effect locking, that seal, conveniently use.

For realizing above-mentioned purpose, the technological scheme that the utility model adopts is: a kind of novel screw comprises nut, screw thread; Screw thread is made up of internal thread and outside thread, sets up one deck elastomer between internal thread and the outside thread, and said elastomer embeds the gap between tooth summit and the tooth peak base fully.

Preferably, the elastomer of novel screw is that nylon material is formed, and nylon material is Powdered.

Preferably, the nylon material of novel screw embedding is the half-turn shape.

Preferably, the nylon material of novel screw embedding is whole circle.

The utility model beneficial effect:

That novel screw can be accomplished is locking, sealing, the convenient use.Said novel screw need not to purchase in addition locking/black box, only needs a kind of nylon glue of precoating on screw thread, fundamentally solved between inside and outside thread that the gap produced was loosening, and processing cost is low, efficient is high.

Description of drawings

Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:

Fig. 1 is the structural drawing of the utility model screw.

Embodiment

To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.

Embodiment 1:

Fig. 1 is the structural drawing of the utility model screw, can be known by Fig. 1, and this novel screw comprises nut 1, screw thread 2; Screw thread 2 is made up of internal thread 3 and outside thread 4, sets up one deck elastomer nylon glue 5 between internal thread 3 and the outside thread 4, and described elastomer embeds the gap between tooth summit and the tooth peak base fully.

The elastomer of said novel screw is that nylon material is formed, and nylon material is Powdered.

The nylon material that said novel screw embeds is the half-turn shape.

The nylon material that said novel screw embeds is whole circle.

Said novel screw comprises the screw and a kind of nylon material that have the machine pitch thread.Through in the gap of outside thread and internal thread, setting up one deck nylon elastomer, make screw thread have frictional force (rebounding force, steering resistance), thereby effectively limit the relative movement of helical thread portion, make it to have excellent anti-vibration and shock resistance effect.When precoating screw thread and inner bolt hole cooperatively interacted, nylon material embedded the gap between tooth summit and the tooth peak base fully, has brought into play excellent sealing effect from face, and sealing effect is given full play at the position that possibly produce dynamic pressure.

The utility model screw comprises screw and a kind of nylon material of an organic pitch thread.Nylon material is Powdered.After preheating that screw is heated, nylon powder is sprayed and is merged on screw thread.

More than technological scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.

Claims

1. a novel screw comprises nut, screw thread; It is characterized in that screw thread is made up of internal thread and outside thread, set up one deck elastomer between internal thread and the outside thread, said elastomer embeds the gap between tooth summit and the tooth peak base fully.

2. according to the said novel screw of claim 1, the elastomer that it is characterized in that this novel screw is that nylon material is formed, and nylon material is Powdered.

3. according to claim 1 or 2 said novel screws, it is characterized in that the nylon material that this novel screw embeds is the half-turn shape.

4. according to claim 1 or 2 said novel screws, it is characterized in that the nylon material that this novel screw embeds is whole circle.
