Abstract

The utility model relates to a fastening bolt, comprising a bolt body and a fastening. The fastening is a ring-shaped sleeve barrel, and a plurality of channels can be formed on ring surfaces around the ring-shaped sleeve barrel along the axis direction, wherein, one channel runs through the whole axial ring surface, and the rest channels present the state without running through the axial ring surface; the cambered surface whose number is the same with that of the channel is formed between the channels; each cambered surface is convexly provided with a first lug and a second lug; the first projection is formed into an inclined plane by facing a square of pushing and pulling portion of the body, and a vertical plane is formed corresponding to the other end of the inclined plane. When the fastening bolt of the utility model is embedded in the screw hole of the wall surface, the construction is easy, and the anchoring effect of the fastening is good.

Description

Clamping bolt

The utility model relates to a kind of clamping bolt, and especially a kind of can forcing embeds the wall wall with as the fixing bolt of article.

In daily life, often run into the situation that article need be hung on the wall, no matter for what reason, carry out this work, the supporter or the fixed block that can be fixed in wall at first must be arranged.This fixture the most commonly is commonly called as the clamping bolt into " gecko ", in use, holes with electric drill one on wall earlier, clamping bolt is embedded wherein again, finishes fastening purpose by screwing nut.Therefore, provide enough fastening forces, just can make bolt bear the weight of assembling article securely.The key of this problem is the matching property of boring and clamping bolt, when promptly will make bolt embed the wall screw, and more easily construction, simultaneously, requiring can have good fastening effect after screwing.Present product, the two often can not be held concurrently and get it.

The purpose of this utility model is that a kind of clamping bolt will be provided, and not only can embed boring easily, and can obtain good fastening effect, possesses stronger tensile strength.

The purpose of this utility model is achieved in that a kind of bolt, comprise a bolt body and a fastener, described body leading portion is provided with a screw section, back segment is provided with a belled part, between belled part and screw section, form one and lean portion, and an end of this relative screw section, belled part forms the portion of pulling out that pushes away of tapered diameter toward the screw section direction, wherein, described fastener is a ring-shaped sleeve, anchor ring is prolonging axial direction and can form some conduits around it, wherein a conduit is to run through whole axial anchor ring, to make things convenient for this packing element when assembling, to be set in the body belled part, all the other conduits then are the state that does not run through axial anchor ring, then form the cambered surface identical with conduit quantity between conduit and conduit, then convex with first projection and second projection on each cambered surface, first projection is a side who pushes away the portion of pulling out towards body and form an inclined-plane, the other end on described relatively inclined-plane then forms a vertical surface, can provide a convenient construction and the more good clamping bolt of fastening effect by means of fastener.

The utility model has the advantages that: clamping bolt of the present utility model is constructed when embedding the wall screw easily, and simultaneously, by means of the projection that is convexly equipped with, the fastener good fastening effect possesses stronger tensile strength.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the stereogram according to the clamping bolt that the utility model proposes;

Fig. 2 is the side view according to the clamping bolt that the utility model proposes;

Fig. 3 is the plan view according to the clamping bolt that the utility model proposes;

Fig. 4 is the action schematic representation one when being forced into wall according to the clamping bolt that the utility model proposes;

Fig. 5 is the action schematic representation two when being forced into wall according to the clamping bolt that the utility model proposes.

Below in conjunction with accompanying drawing and most preferred embodiment thereof the concrete structure that the utility model proposes is further described.

As Fig. 1,2, shown in 3, the clamping bolt that the utility model proposes comprises a bolt body 10 and a fastener 20, described body 10 leading portions are provided with a screw section 11, back segment is provided with a belled part 12, between belled part 12 and screw section 11, form one and lean portion 13, one end of 12 relative screw sections 11, above-mentioned belled part forms the portion of pulling out 121 that pushes away of tapered diameter toward screw section 11 directions, and the structure of above-mentioned body 10 is identical with known product, wherein, described fastener 20 is a ring-shaped sleeve, anchor ring is prolonging axial direction and can form some conduits 21 around it, 22, and

conduit

21,22 sum is good with three, present embodiment is done explanation with three, wherein a conduit 21 crosses whole axial anchor ring, to make things convenient for this fastener when assembling, to be set in the body belled part, 22 of all the other conduits are the state that does not run through axial anchor ring,

conduit

21,22 then form and conduit 21, the cambered surface 23 that 22 total quantitys are identical, then convex with first projection 23 and second projection 25 on each cambered surface 23, first projection 24 is on a square one-tenth one inclined-plane 241 that pushes away the portion of pulling out 121 towards body 10, and the other end on this inclined-plane 241 then forms a vertical surface 242 relatively.

As shown in Figure 4, the utility model in use, be that the body 10 that will be assembled into one is forced into wall boring 40 with fastener 20 to scheme the upward arrow direction, be provided with first projection 24 and second projection 25 on each cambered surface 23 because of fastener 20 simultaneously, can increase fastening effect, in addition, the inclined-plane 241 of first projection 24 and the design of vertical surface 242, the utility model is gone out being forced into 40 o'clock Yi Jinnan of boring, be easy to construction, and have better tension effect after 40 being forced into boring.

At last as shown in Figure 5, after the utility model embeds boring 40 inside, the user rotates nut 30 more in a clockwise direction, then can spur body 10 moves outward, and by means of the pushing tow of pushing face-drawing 121, make each cambered surface 23 of fastener 20 be subjected to shoring of pushing face-drawing 212 and expansion outward, strengthen fastening effect of the present utility model and resistance to tension once more.
