Detailed description of the invention
The purpose of this utility model is to provide a kind of enameled wire spool, in the gap that the structure design of this enameled wire spool can prevent enamel wire from snapping between end cap 1 and cylindrical shell 2 effectively.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 4, the enameled wire spool that the utility model embodiment provides comprises cylindrical shell 2 and relative two end caps 1, wherein two end caps 1 are connected with the two ends of cylindrical shell 2 respectively, focus on, the both ends of cylindrical shell 2 are provided with multiple protruding 2a, and multiple protruding 2a distributes along the circumference of cylindrical shell 2.The end face at i.e. cylindrical shell 2 two ends all arranges multiple protruding 2a, and the multiple protruding 2a of cylindrical shell 2 end is positioned at circumferentially same, has gap between two adjacent protruding 2a, and the diameter of the outermost place circumference of multiple protruding 2a is identical with the external diameter of cylindrical shell 2.The end face of end cap 1 is provided with multiple slot 1a, and multiple protruding 2a can distribute in the multiple slot 1a of insertion.Namely end cap 1 multiple slot 1a is set on the end face be connected with cylindrical shell 2, after cylindrical shell 2 is connected with end cap 1, multiple protruding 2a inserts in multiple slot 1a respectively.
In the enameled wire spool that the utility model embodiment provides, end due to cylindrical shell 2 has multiple protruding 2a, multiple protruding 2a inserts in multiple slot 1a of end cap 1 respectively, the groove bottom land formed between two adjacent protruding 2a and end cap 1 offset, gap between cylindrical shell 2 and end cap 1 is separated by multiple protruding 2a like this, the enamel wire be wrapped on cylindrical shell 2 is directly fastened on multiple protruding 2a, protruding 2a stop lacquers envelope curve enters in gap, and then the situation causing unwrapping wire stuck in the gap that can prevent enamel wire from snapping between end cap 1 and cylindrical shell 2.
For the ease of processing, its protrusions 2a can be arranged multiple escape groove 2b and be formed by the end at cylindrical shell 2, the part between adjacent two escape groove 2b forms protruding 2a.Namely directly offer escape groove 2b in the end of cylindrical shell 2, escape groove 2b forms the gap between two adjacent protruding 2a.Certainly, also protruding 2a can be processed separately in the end of cylindrical shell 2, in this no limit.
Further, when protruding 2a inserts after in slot 1a, the bottom land of escape groove 2b and the end face of end cap 1 offset.So ensure that the gap between cylindrical shell 2 and end cap 1 is less, after can preventing long-time use, protruding 2a departs from escape groove 2b.
Wherein, multiple protruding 2a can be uniformly distributed along the circumference of cylindrical shell 2, so ensure that the stress equalization of cylindrical shell 2 and end cap 1.
In order to strengthen the Joint strenght between end cap 1 and cylindrical shell 2, wherein can also be bolted to connection between end cap 1 and cylindrical shell 2, being so also convenient to dismounting end cap 1 and cylindrical shell 2, be convenient to safeguard.
In addition, end cap 1 and cylindrical shell 2 can be ABS (acrylonitrile-butadiene-phenylethylene terpolymer) material.Certainly, end cap 1 can also be other plastic material, in this no limit.
Wherein, end cap 1 can be disc, and the axis of end cap 1 and the dead in line of cylindrical shell 2 are arranged, the location of end cap 1 of being so more convenient for.
In this specification sheets, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
