Abstract
The utility model provides a kind of plastic dowel sleeve, comprise body, it is characterized in that, described body is column, described tubular body is provided with cone tank, and described body is provided with retaining tooth, spin-ended post, a wire casing, and described retaining tooth is arranged on the both sides of described its bottom, described wire casing is arranged in the middle of described retaining tooth, and described wire casing both sides are provided with spin-ended post.The utility model provides a kind of structure simple, uses and installs accurate quick, shock-resistant, on-deformable plastic dowel sleeve.
Description
Technical field
The utility model relates to a kind of fastening piece, is specifically related to a kind of plastic dowel sleeve.
Background technique
Current plastic dowel sleeve is widely used in wall brick, the setscrew aspects such as cement wall, along with development and the market demand expansion of science and technology, the consumption of expansion tube increases gradually, people, when using existing plastic expansion, occur that expansion is not fastening, comes off from installation place sometimes, intensity is low, insecure, the bad phenomenon such as fracture, and these problems not only have influence on production, and also have potential safety hazard, namely need a kind of durable expansion tube.It is simple that the utility model provides a kind of structure, uses and install accurate quick, shock-resistant, not yielding, and difficult drop-off is durable in use, reduces the plastic dowel sleeve of construction risk.
Model utility content
The utility model provides a kind of plastic dowel sleeve, installs accurate quick fastening, difficult drop-off, not yielding, durable in use.In order to realize technique scheme, the utility model adopts following technological scheme:
A kind of plastic dowel sleeve, comprise body, conduit saddle, it is characterized in that, described body is column, and the termination of described body is brachycephalic, the afterbody of described body is provided with conduit saddle, described tubular body is provided with cone tank, and described body is provided with retaining tooth, spin-ended post, wire casing, and described retaining tooth is arranged on the both sides of described body afterbody, described wire casing is arranged on described body in the middle of two described retaining teeth, and the both sides of described wire casing length direction are equipped with spin-ended post.
A kind of plastic dowel sleeve that the utility model provides, preferably, the vertex of a cone of described cone tank is arranged on the central position of described wire casing.
A kind of plastic dowel sleeve that the utility model provides, preferably, described wire casing is rectangular, and described wire casing runs through whole body.
A kind of plastic dowel sleeve that the utility model provides, preferably, described retaining tooth presents and is made up of two triangular facets and a cambered surface on described body, and described retaining tooth is solid.
A kind of plastic dowel sleeve that the utility model provides, preferably, the relative position of two described retaining teeth revolves turnback to realize around described body central axle with any point on described retaining tooth.
The beneficial effects of the utility model are: a kind of plastic dowel sleeve that the utility model provides, when expandable nail enters into plastic dowel sleeve along described cone tank, described cone tank prevents breaking of plastic dowel sleeve, by the extruding of expandable nail, expansion tube is inflated nail, and outwards support is large, very large pressure is formed in the outside of expansion tube, described spin-ended post and described retaining tooth are tightly embedded in wall, described spin-ended post prevents loosening of plastic dowel sleeve, and prevent plastic dowel sleeve to be out of shape, the setting of described retaining tooth effectively prevent coming off of plastic dowel sleeve, so once installation, then be difficult to be pulled out.It is simple that the utility model provides a kind of structure, uses and install accurate quick, shock-resistant, not yielding, prevents this from sliding in porthole, reduce the plastic dowel sleeve of construction risk.
Accompanying drawing explanation
Carry out describing in detail or preferably to preferred implementation of the present utility model below in conjunction with accompanying drawing, wherein,
Fig. 1 is the schematic top plan view of plastic dowel sleeve;
Fig. 2 is the schematic side view of plastic dowel sleeve;
Fig. 3 is the sectional drawing of plastic dowel sleeve;
Fig. 4 is the retaining tooth schematic diagram of plastic dowel sleeve.
Embodiment
Embodiment with reference to figures 1 through 4 pairs of a kind of plastic dowel sleeves of the utility model is described further:
A kind of plastic dowel sleeve, comprise body 1, conduit saddle 2, it is characterized in that, described body 1 is in column, and the termination of described body 1 is brachycephalic, the afterbody of described body 1 is provided with conduit saddle 2, described body 1 inside is provided with cone tank 3, and described body 1 is provided with retaining tooth 4, spin-ended post 5, wire casing 6, and described retaining tooth 4 is arranged on the both sides of described body 1 afterbody, described wire casing 6 is arranged on described body 1 in the middle of two described retaining teeth 4, and the both sides of described wire casing 6 length direction are equipped with spin-ended post 5.
The vertex of a cone of described cone tank 3 is arranged on the central position of described wire casing 6, described wire casing 6 is rectangular, and described wire casing 6 runs through whole body, described retaining tooth 4 presents and is made up of two triangular facets 7 and a cambered surface 8 on described body 1, and described retaining tooth 4 is solid, the relative position of two described retaining teeth 4 revolves turnback to realize around described body 1 central shaft with any point on described retaining tooth 4.
Embodiment of the present utility model is: first punch on wall with the drill bit mated with plastic dowel sleeve, plastic dowel sleeve is put into hole, then expandable nail is knocked in plastic dowel sleeve, expandable nail diameter of bore is less than the diameter of described conduit saddle, after expandable nail enters into plastic dowel sleeve along described cone tank 3, by the extruding of expandable nail, expansion tube is inflated nail, and outwards support is large, very large pressure is formed in the outside of expansion tube, described spin-ended post 5 and described retaining tooth 4 are tightly embedded in wall, thus closely compress with the hole beaten on wall, thus reach fixation, and described retaining tooth 4 prevents plastic dowel sleeve to come off, so once installation, then be difficult to be pulled out.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technological scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
