Abstract
The utility model relates to a sleeve type expanding bolt which comprises a screw cap, a screw rod, a cone, a sleeve and a shim, wherein, the screw cap is fixedly connected with the top of the screw rod to form a bolt head; the screw rod and the bolt head compose a screw bolt with the bolt head; the cone is a conical screw cap which can be screwed with the screw rod, and the surface of the segment adjacent to the screw rod is conical. The sleeve type expanding bolt has strong clamping force when arranged inside a hole wall; because only the bolt head is exposed outside the hole wall after the sleeve type expanding bolt is installed, the surrounding environment of a hanging object can not be spoiled. The utility model has better shockproof performance and slip resistance for use.
Description
The utility model relates to a kind of telescopic EXPANSION ANCHOR BOLTS of improvement.
Telescopic EXPANSION ANCHOR BOLTS is to enter the distortion of sleeve behind the wall and effectively clip is in hole wall by bolt, and people use its fixed on the wall object usually.For the sleeve that makes bolt has better clip effect in hole wall, the applicant (designer) has proposed to be equipped with the design proposal that several outwards have the lug at angle of inclination above the sleeve openings groove in Chinese patent 97206600.4 applications, during use, continuous distortion along with the sleeve openings groove, the powerful clip of these lugs is on wall surface of the hole, improved the force intensity that is subjected to of bolt greatly, practicability is stronger, but the relatively poor problem of the aesthetic of this EXPANSION ANCHOR BOLTS also there is not solution.Shown in Figure 3 is sleeve outwards urgent action schematic representation of opening in hole wall of the EXPANSION ANCHOR BOLTS in the above-mentioned patent application, be connected with in the bottom when nut 62 on the screw rod 61 of cone make EXPANSION ANCHOR BOLTS after the constantly rotation packing sleeve 63 tightly clip in hole wall, end back EXPANSION ANCHOR BOLTS is installed just enters user mode, and at this moment the top of screw rod 61 protrudes in 62 1 sections on nut, and this has influenced greatly hangs the thing aesthetic of integrated environment on every side.
The purpose of this utility model is to design a kind of not only also do not destroy the integrated environment aesthetic feeling by force but also in use in porthole inwall clip power and telescopic preferably EXPANSION ANCHOR BOLTS of shock resistance.
The purpose of this utility model be achieved in that telescopic EXPANSION ANCHOR BOLTS comprise nut, screw rod, cone, the sleeve that has lug above the opening slot and place nut and sleeve between pad, wherein said fixed by nut is connected in the top of screw rod, become a bolt head, screw rod and bolt head are formed a bolt that has bolt head, described cone be one place the screw rod bottom, can screw togather with screw rod and be conical circular cone nut near this section surface of screw rod.
Above-mentioned circular cone nut has on conical this section surface and is equipped with anti-skidding concave convex texture.
In above-mentioned telescopic EXPANSION ANCHOR BOLTS, between sleeve and pad, be equipped with a pad tube.
Telescopic EXPANSION ANCHOR BOLTS of the present utility model, not only strong in porthole inwall clip power, and owing to nut fixedly connects together with screw rod, become a bolt that anchor stud head is arranged, the distortion of sleeve is the circular cone nut that is in the screw rod bottom by the screw rod packing during use, therefore, install stay hole wall outer only be bolt head, can not destroy the aesthetic feeling of hanging thing integrated environment on every side, in addition, be equipped with pad and pad tube in the utility model between bolt head and the sleeve, the trochoidal surface of circular cone nut has anti-skidding concave convex texture, and is shockproof and non-skid property is all better in the use.
Details are as follows to structure of the present utility model according to an embodiment's accompanying drawing below:
Fig. 1 is an embodiment's of the utility model a three-dimensional exploded view;
Fig. 2 is that the telescopic EXPANSION ANCHOR BOLTS of Fig. 1 is outwards compeled the action diagram of opening in the hole wall inner sleeve;
Fig. 3 is that existing telescopic EXPANSION ANCHOR BOLTS is in the outwards urgent action diagram of opening of hole wall inner sleeve;
Structure of the present utility model is referring to Fig. 1, telescopic EXPANSION ANCHOR BOLTS comprises nut 11, screw rod 12, cone 5, above opening slot 42, have the sleeve 4 of lug 41 and place nut 11 and the pad 2 of 4 in sleeve, wherein nut 11 is fixedly connected on the top of screw rod 12, become a bolt head 11, screw rod 12 and bolt head 11 are formed a bolt 1 that has bolt head 11, cone 5 is one and places screw rod 12 bottoms, can screw togather with screw rod 12, and this section surface 51 near screw rod 12 is conical circular cone nut 5, in use be anti-skidding, be equipped with anti-skidding concave convex texture on conical this section surface 51 in having of circular cone nut 5.
In above-mentioned telescopic EXPANSION ANCHOR BOLTS, be equipped with a pad tube 3 at sleeve 4 and 2 on pad.
Referring to Fig. 1,2, because bolt head 11 is fixedly to connect together with screw rod 12 to form a bolt 1 that has bolt head 11, the distortion of sleeve 4 is the circular cone nuts 5 that are screwed together in screw rod 12 bottoms by screw rod 12 packings in use, install stay hole wall outer only be nut, can not destroy the aesthetic feeling of hanging thing integrated environment on every side, in addition, be equipped with pad 2 and pad tube 3 between bolt head 11 in the utility model and the sleeve 4, shockproof properties is better in the use.
The shape of the bolt head 11 in the utility model can be (as shown in Figure 1, 2) of hexagon nut shape, also can be the recessed reversing screw gudgeon shape of tack or plush copper, also can be tack or plush copper a recessed word nut shape or the like (all not showing among the figure) multiple shape.
