Abstract
The utility model discloses an internal thread protects stopper, including one end open -ended stopper neck, stopper neck top is provided with the gag ring, and the inner ring and the opening of stopper neck of gag ring are connected, and the stopper neck periphery side of laminating mutually with the internal thread is provided with the bulge loop, the upper surface of gag ring or stopper neck be provided with be used for pulling protect the stopper realization fill in if open pull the piece. This internal thread protects stopper is rational in infrastructure simple, pulls the piece through being provided with on the gag ring, and the operator can pull a separation sheet metal component and an internal thread protects stopper by direct centre gripping, need not use other handling instruments, conveniently realizes fast loading and unloading.
Description
Technical field
The utility model relates to screw thread and protects plug, is specifically related to a kind of internal thread and protects plug.
Background technology
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 component 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 internal thread hole, there is fit clearance, 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 fit clearance, when dusting, there is amount of powder can enter interior threaded surface along internal screw workpiece chamfering, fill plug and screwed hole gap, powder is after solidification, plug and workpiece are combined together, during assembling, plug takes out difficulty, and screwed hole surface does not protect completely, easily cause partial threads hole first need return tooth process could assemble, affect operating efficiency.Disclose a kind of internal thread protection plug of instrument Fast Installation in CN204113850U, but it is more loaded down with trivial details to adopt erecting tools to install in actual use, therefore, is necessary to protect internal thread of the prior art to fill in the improvement of row structure.
Utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of structure internal thread simple, easy to use to protect plug.
For realizing above-mentioned technique effect, the technical solution of the utility model is: a kind of internal thread protects plug, it is characterized in that, comprise the plug neck of one end open, described plug neck top is provided with gag ring, and the inner ring of described gag ring is connected with the opening of plug neck, and the plug neck circumferential lateral surface fitted with internal thread is provided with bulge loop, the upper surface of described gag ring or plug neck is provided with for drawing the traction piece protecting plug realization plug and establish or open, and described traction piece protrudes from the extension of described gag ring.
Preferred technical scheme is, described traction piece is traction item or bail, and described traction item or bail are fixedly connected with the upper surface of gag ring.
Preferred technical scheme is, the stiff end width of described traction item is equal to or less than free end width, and the upper surface of traction item and/or lower surface are provided with the raised line for increasing frictional force.
Preferred technical scheme is, the basal diameter of described plug neck is slightly less than plug neck top external profile diameter, rounding off between the peripheral side of described plug neck and bottom surface.
Preferred technical scheme is, the cross section of described bulge loop is semicircle or triangle.
Advantage of the present utility model and beneficial effect are:
It is rationally simple that this internal thread protects plug structure, and by being provided with traction piece on gag ring, operator directly can clamp traction piece separation sheet metal component and internal thread protects plug, does not need to use other handling instruments, conveniently realizes quick despatch.

Fig. 1 is the structural representation that the utility model internal thread protects plug embodiment 1;
Fig. 2 is the plan structure schematic diagram that in Fig. 1, internal thread protects plug;
Fig. 3 is the plan structure schematic diagram that the utility model internal thread protects plug embodiment 2.
In figure: 1, fill in neck; 2, gag ring; 3, bulge loop; 4-1, traction item; 4-2, bail; 5, raised line.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Embodiment 1
As depicted in figs. 1 and 2, embodiment internal thread protects plug, comprise the plug neck 1 of one end open, plug neck 1 top is provided with gag ring 2, the inner ring of gag ring 2 is connected with the opening of plug neck 1, plug neck 1 circumferential lateral surface fitted with internal thread is provided with bulge loop 3, and the upper surface of gag ring 2 or plug neck 1 is provided with for drawing the traction piece protecting plug realization plug and establish or open, and traction piece protrudes from the extension of gag ring 2.
Traction piece is traction item 4-1, and traction item 4-1 is fixedly connected with the upper surface of gag ring 2.
The stiff end width of traction item 4-1 is equal to or less than free end width, upper surface and the raised line 5 be provided with for increasing frictional force of traction item 4-1.Due to rubber surface relatively cunning, therefore in use, the finger acting surface of raised line and operating personnel produces and rubs, and realizes the light unlatching protecting plug.
The basal diameter of plug neck 1 is slightly less than plug neck 1 top external profile diameter, rounding off between the peripheral side of plug neck 1 and bottom surface.
The cross section of bulge loop 3 is semicircle.
Embodiment 2
As shown in Figure 3, embodiment 2 is with the difference of embodiment 1, and traction piece is bail 4-2, and during use, the finger acting surface of the inner ring surface of bail 4-2 and outer ring surface and operating personnel produces and rubs, and realizes the light unlatching protecting plug.The surface of bail also can be set to pitted skin or have raised line, can increase frictional force equally.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (5)
