Abstract
The utility model discloses a kind of internal thread protection plug, include external screw-thread and inner mounting hole, external structure include successively be less than internal thread importing end, with the outside thread of internal thread adaptation and the screw thread seam end being greater than internal thread, screw thread seam end is transited into a reciprocal chamfering naturally from outside thread, the external diameter of chamfering is greater than externally threaded large footpath, the angle of chamfering is greater than 45 °, is less than 90 °, be convenient to protect internal screw workpiece, during the process such as avoid it to dust, powder is covered in interior threaded surface, affects internal thread usability; Plug inside includes the mounting hole with setting tool adaptation, is convenient to adopt setting tool easily and fast plug to be loaded in (or shifting out) internal screw workpiece; The utility model is reasonable in design, structure is simple, beautiful shape.
Description
Technical field
The utility model relates to a kind of screw thread protection plug structure, particularly relates to a kind of internal thread protecting glue plug structure.
Background technique
At present in panel beating manufacturing, adopt the assembling mode ubiquity that bolt is connected with internal thread, and for ease of assembling, together with inner thread piece is generally riveted with workpiece or is welded in, and when rear operation dusts antirust treatment to sheet metal part surface, interior threaded surface easily covers molding powder, screw thread is caused to block, common solution adopts plug to fill protection, and between plug and interior threaded hole, there is matching gap, easily spray at workpiece, cleaning waits plug in surface pretreatment process to drop, do not reach when rear operation is dusted and protect internal thread effect, and due to matching gap, when dusting, there is amount of powder can enter interior threaded surface along internal screw workpiece chamfering, fill plug and tapped hole gap, powder is after solidification, plug and workpiece are combined together, during assembling, plug takes out difficulty, and tapped hole surface does not protect completely, easily cause partial threads hole first need return tooth process could assemble, affect working efficiency.
Summary of the invention
The utility model provides a kind of better protection internal whorl to avoid being covered and easy-disassembling-assembling internal thread protecting glue plug structure by powder to solve deficiency of the prior art.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of internal thread protection plug, described plug contains external screw-thread structure and inner mounting hole, the external screw-thread structure of described plug includes the importing end being less than internal thread successively, with outside thread and the screw thread seam end being greater than internal thread of internal thread adaptation, importing end is easy in plug loading internal thread, outside thread and internal thread adaptation, be convenient to can not drop in protection process, and better protection internal whorl is avoided being covered by powder, screw thread seam end is convenient to control plug and is screwed into the degree of depth in internal screw workpiece, the inside of described plug includes the mounting hole with setting tool adaptation, be convenient to load easily and fast in (or shifting out) internal screw workpiece.
As a kind of preferred version of internal thread protection plug described in the utility model; the screw thread seam end of described plug is transited into a reciprocal chamfering naturally from outside thread; the external diameter of chamfering is greater than externally threaded large footpath; the angle a of chamfering is greater than 45 °, is less than 90 °; be conducive to plug protection internal thread chamfering, seal internal thread ragged edge completely, avoid powder to enter in interior threaded hole.
As a kind of preferred version of internal thread protection plug described in the utility model, the inside mounting hole of described plug is through hole or blind hole, can select according to the actual requirements.
The beneficial effects of the utility model:
Internal thread protection plug described in the utility model, containing external screw-thread structure and inner mounting hole, external screw-thread well protects internal thread holes and avoids it in the processes such as workpiece dusts, and powder covers its thread surface, affects its usability; Inner mounting hole is convenient to plug and is easily adopted suitable instrument to load in (or shifting out) internal screw workpiece fast; The utility model is reasonable in design, structure is simple, beautiful shape.

Fig. 1 is the structural representation of internal thread described in the utility model protection plug.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is that internal thread protection plug and internal screw workpiece assemble cross-sectional schematic.
Fig. 4 adopts tool assemble process schematic.
Wherein: 1, plug 2, internal screw workpiece 3, setting tool 11, importing end 12, outside thread 13, screw thread seam end 14, mounting hole 15, chamfering a, angle
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, for structural representation and the sectional view of internal thread protection plug described in the utility model, as can be seen from figure we, a kind of internal thread protection plug 1, include external screw-thread structure and inner mounting hole, external screw-thread structure includes the importing end 11 being less than internal thread successively, with outside thread 12 and the screw thread seam end 13 being greater than internal thread of internal thread adaptation, screw thread seam end 13 is transited into a reciprocal chamfering 15 naturally from outside thread 12, the external diameter of chamfering 15 is greater than the large footpath of outside thread 12, the angle a of chamfering 15 is greater than 45 °, be less than 90 °, be convenient to protection internal screw workpiece and internal thread chamfering, during the process such as avoid internal screw workpiece to dust, powder is covered in (as shown in Figure 3) in interior threaded surface, plug 1 inside includes the mounting hole 14 with setting tool 3 adaptation, be convenient to adopt setting tool 3 easily and fast plug 1 to be loaded in (or shifting out) internal screw workpiece 2 (as shown in Figure 4).
Although be illustrated mode of execution of the present utility model in specification, these mode of executions just as prompting, should not limit protection domain of the present utility model.In the scope not departing from the utility model aim, carry out various omission, displacement and change all should be included in protection domain of the present utility model.
