Abstract
The utility model discloses a self-expanding rubber plug. The self-expanding rubber plug comprises a pipe body, wherein an expanding section with a split pipe wall is formed on the pipe body; the expanding section is formed at the end, plugged into a mounting hole, of the pipe body; a hole of the expanding section is shaped like an outward flare opening; a column-shaped expanding head is provided; one section of the column-shaped expanding head is inserted into the hole of the expanding section and the other section of the column-shaped expanding head is exposed outside the pipe body; and a head for expanding the expanding section along with the insertion of the column-shaped expanding head is formed at the section, inserted into the expanding section, of the column-shaped expanding head. The expanding section of the rubber plug is expanded at the bottom of the mounting hole, so the expansion fastening performance of the rubber plug is enhanced. Therefore, the rubber plug has the automatic expanding function when being punched into the mounting hole, and is simple in structure and convenient and quick to mount.
Description
Technical field
The utility model relates to expansion plug technical field.
Background technique
Traditional expansion plug is comprised of an expansion tube, need to be screwed in expansion tube with self tapping screw, forces expansion tube to expand and oppresses the mounting hole wall, realizes fastening installation.When the expansion plug is filled in mounting hole, there is no fastening effect before not being screwed into self tapping screw, therefore, mounting hole boring often can occur excessive, cause when being screwed into self tapping screw, the expansion plug and then rotates, and can't be screwed into self tapping screw.And the expansion of this expansion plug is to expand gradually from outside to inside, plug easily occurs and breaks away from the mounting hole phenomenon.As seen, still there is defective in traditional expansion plug at the expansion fastening aspect of performance, is necessary it is made improvements.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of when filling in mounting hole, has the plug of automatic expansion function.
For solving the problems of the technologies described above the technological scheme that adopts: a kind of self-expanding plug, comprise a body, be formed with the expansion arc of one section tube wall division on body, it is characterized in that: described expansion arc is formed on that end that body is filled in mounting hole, and the hole of expansion arc is set as and outwards is the enlarging shape, an if cylindricality expansion-head, in the hole that wherein a section is inserted into expansion arc of cylindricality expansion-head, another section is exposed outside body, and that section that the cylindricality expansion-head is inserted into expansion arc is formed with along with the insertion of cylindricality expansion-head the head of expansion arc distending.
On the basis of the above, the head of described cylindricality expansion-head is set as the cone column with the hole shape of hose expansion section coupling.
On the basis of the above, the outer wall of described body is provided with pawl.
The beneficial effect that adopts the utility model to bring: the utility model is located at the expansion arc of plug that section of filling in the mounting hole bottom, when squeezing into plug, along with being knocked, plug enters in mounting hole, the cylindricality expansion-head is mounted the bottom in hole and withstands, headed into by force in mounting hole, the expansion arc distending of plug, thereby plug is fastened in mounting hole, because the plug expansion arc is to expand in the bottom of mounting hole, strengthened the expansion fastening performance of plug.As seen, the utility model is a kind of when squeezing into mounting hole, the plug that just has the automatic expansion function, and simple in structure, quick and easy for installation.

Fig. 2 is the pipe structure schematic diagram of the utility model self-expanding plug;
Fig. 3 is the structural representation of the cylindricality expansion-head of the utility model self-expanding plug.
Embodiment
As Figure 1-3, a kind of self-expanding plug comprises a body 1, is formed with the expansion arc 1.1 of one section tube wall division on body 1.Described expansion arc 1.1 is formed on that end that body 1 is filled in mounting hole, and the hole 1.2 of expansion arc 1.1 is set as and outwards is the enlarging shape.An if cylindricality expansion-head 2, in the hole 1.2 that wherein a section is inserted into expansion arc 1.1 of cylindricality expansion-head 2, another section is exposed outside body 1, and that section that cylindricality expansion-head 2 is inserted into expansion arc is formed with along with the insertion of cylindricality expansion-head 2 the head 2.1 of expansion arc 1.1 distendings.
In the present embodiment, the head 2.1 of described cylindricality expansion-head 2 is set as the cone column with hole 1.2 form fit of body 1 expansion arc 1.1.In order to strengthen the fastening performance of plug, the outer wall of described body 1 is provided with pawl 1.3.
During installation, the degree of depth and caliber punching according to the body 1 of plug, plug is filled in mounting hole, then clashed into plug by instrument, make plug body 1 enter mounting hole to the greatest extent, in this course, cylindricality expansion-head 2 is headed into the expansion arc 1.1 of body 1, with expansion arc 1.1 distendings, is pressing the hole wall of mounting hole, thereby plug is fastened in mounting hole, installs very convenient quick.
Claims (3)
1. self-expanding plug, comprise a body, be formed with the expansion arc of one section tube wall division on body, it is characterized in that: described expansion arc is formed on that end that body is filled in mounting hole, and the hole of expansion arc is set as and outwards is the enlarging shape, establishes a cylindricality expansion-head, in the hole that wherein a section is inserted into expansion arc of cylindricality expansion-head, another section is exposed outside body, and that section that the cylindricality expansion-head is inserted into expansion arc is formed with along with the insertion of cylindricality expansion-head the head of expansion arc distending.
2. self-expanding plug according to claim 1 is characterized in that: the head of described cylindricality expansion-head is set as the cone column with the hole shape coupling of hose expansion section.
3. self-expanding plug according to claim 2, it is characterized in that: the outer wall of described body is provided with pawl.
