Abstract
The utility model relates to an expansion pin, relating to a device for fastening or fixing component parts. The expansion pin comprises a cylindrical pin body and a plug which can be arranged inside the cylindrical pin body, wherein, one end of the cylindrical pin body is provided with a flange, and the other end forms a cone shape. A cone-shaped cylinder wall is divided into four to eight parts in an axial direction. Teeth are arranged on the outer surfaces of each divided cone-shaped cylinder wall. The outside diameter of the plug is matched with the inside diameter of the cylindrical pin body. One end of the plug forms a cone shape. A convex shoulder is arranged on the periphery surface of one cone-shaped end of the plug. The expansion pin has the advantages of firm connection, difficult disassembly, complete arrangement of the plug inside the cylindrical pin body, no exposition, safety, and convenient connection.
Description
The utility model relates to a kind of device of fastening or fixed component.
When existing setscrew was connected member with fixture, what lean on was the drum outer wall of expansion and the friction of fixture, and fixedly fastness is still not enough for it; The nut recruitment prodigiosin of setscrew unloads, if be used for door, window fixedly the time, safety inadequately, protruding the exposing outside of its screw one end both influenced attractive in appearancely, also easily bumped other object.
The purpose of this utility model is: a kind of technological scheme of expandable nail is provided, and it is connected firmly, and is not quick detachable, safe and reliable after the installation, and embolism places in the cylinder staple body, does not expose, and is easy to connect.
The technical solution of the utility model is: expandable nail comprises cylinder staple body and the embolism that can place in the cylinder staple body, and cylinder staple body one end has flange, and the other end is tapered, and the taper barrel axially is divided into the 4-8 part.On each divided taper barrel outer surface tooth is arranged all, the internal diameter of the external diameter of embolism and cylinder staple body is complementary, and an end of embolism is tapered, on the tapered end outer circumferential face of embolism convex shoulder is arranged.Cylinder staple body has an end of flange that flanged cap is housed.
Major advantage of the present utility model is: fixedly connected firm, not quick detachable, safe and reliable, embolism places in the cylinder staple body entirely, does not have the protruding external part of cylinder staple that is exposed at, and is easy to connect.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1: cylinder staple body schematic representation,
The A-A sectional view of Fig. 2: Fig. 1,
The left view of Fig. 3: Fig. 1,
Fig. 4: the embolism schematic representation,
Fig. 5: the flanged cap schematic representation,
Embodiment 1:
Expandable nail comprises that cylinder staple body (sees Fig. 1, Fig. 2, Fig. 3), place the embolism (see figure 4) in the cylinder staple body, cylinder staple body one end has flange 1, the other end is tapered, the taper barrel axially is divided into 4 five equilibriums, can certainly axially be divided into 5 or 6,7,8 five equilibriums, on each divided taper barrel outer surface tooth 2 is arranged all, the internal diameter of the external diameter of embolism and cylinder staple body is complementary, embolism can just be filled in the cylinder staple body, one end of embolism is tapered, on the tapered end outer circumferential face of embolism convex shoulder 3 (see figure 4)s are arranged, the effect of convex shoulder 3: the one, after embolism is filled in cylinder staple body, the barrel that the tapered end of cylinder staple body is axially cut apart expands, tooth on the divided barrel outer surface embeds in the fixed object simultaneously, and the 2nd, when convex shoulder 3 passed the tapered the other end of cylinder staple body, convex shoulder 3 can stop embolism to be return.
Embodiment 2:
With embodiment 1 difference be: cylinder staple body has an end of flange that the flanged cap (see figure 5) is housed.
Claims (2)
1, expandable nail is characterized in that: comprise cylinder staple body and can place the interior embolism of cylinder staple body, cylinder staple body one end has flange, and the other end is tapered, and the taper barrel axially is divided into the 4-8 part.On each divided taper barrel outer surface tooth is arranged all, the internal diameter of the external diameter of embolism and cylinder staple body is complementary, and an end of embolism is tapered, on the tapered end outer circumferential face of embolism convex shoulder is arranged.
2, according to the described expandable nail of claim 1, it is characterized in that: cylinder staple body has an end of flange that flanged cap is housed.
