Abstract
Disclosed is an expansion bolt. The lower end of a circular tube portion is provided with a taper tube portion integrally connected with the circular tube portion. A plurality of opposite arc-shaped slotted holes are formed in the outer wall of the taper tube portion. An inner screw hole of the circular tube portion is processed into a taper hole. A ring-shaped raised ring is arranged at a position, close to an inlet, of the outer wall of the circular tube portion and is composed of two ring bodies, an acute angle is formed between the first ring body connected with the circular tube portion and the circular tube portion, and the second ring body is connected with the first ring body and is perpendicular to the circular tube portion. Compared with the prior art, the expansion bolt has the advantages of simple structure and process, convenience in producing and mounting, low cost, good effect and the like.
Description
technical field
The present invention relates to a kind of wall connector, particularly relate to a kind of expansion bolt.
background technique
As everyone knows, expansion bolt is one of conventional link of construction industry, existing expansion bolt is made up of the pipe portion be connected as a single entity and Taper Pipe portion, pipe portion establishes screw, and baffle ring is established in the end in pipe portion, in actual use, due to the ring body that baffle ring is vertical with pipe portion, after inserting wall, easily cause baffle ring also to enter in porthole, the connection of screw cannot be realized.
summary of the invention
For solving above deficiency, the object of the present invention is to provide a kind of stable connection, be easy to bolt and connect, simple structure, fabricating cost is cheap, easy for installation, the expansion bolt of long service life.
The present invention mainly takes, and concrete scheme is as follows:
The present invention mainly includes key and bulge loop, and wherein key still comprises pipe portion and Taper Pipe portion, and namely the Taper Pipe portion be connected as a single entity with it is established in the lower end in pipe portion, and the outer wall in Taper Pipe portion establishes the relative slotted eye of several arcs; The interior threaded bore in described pipe portion is also processed as cone shape hole; The outer wall in described pipe portion establishes the bulge loop of ring-type near ingress, bulge loop is made up of two-part ring body, and the ring body that is connected with pipe portion of a part claims acute angle with it, and another part ring body is connected with upper part ring body, and this part ring body and pipe portion perpendicular.
The present invention is in the process of practical application, and pipe portion interior threaded bore is taper hole, like this, coupled at bolt, can increase expansion amplitude, makes it be connected with wall more firm; Baffle ring adopts two-part ring body Connecting format, and baffle ring can be avoided like this to enter porthole, and causing cannot the phenomenon of connecting bolt.
The present invention compared with prior art tool has the following advantages:
1, stable connection, be easy to bolt and connect, simple structure, fabricating cost is cheap, easy for installation, long service life.
accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the present invention.
Number in the figure: 1-key; 2-pipe portion; 3-Taper Pipe portion; 4-slotted eye; 5-cone shape hole; 6-bulge loop.
embodiment
In the schematic diagram of the present invention shown in Fig. 1, key 1 still comprises pipe portion 2 and Taper Pipe portion 3, and namely the Taper Pipe portion be connected as a single entity with it is established in the lower end in pipe portion, and the outer wall in Taper Pipe portion establishes the relative slotted eye 4 of several arcs; The interior threaded bore in described pipe portion is also processed as cone shape hole 5; The outer wall in described pipe portion establishes the bulge loop 6 of ring-type near ingress, bulge loop is made up of two-part ring body, and the ring body that is connected with pipe portion of a part claims acute angle with it, and another part ring body is connected with upper part ring body, and this part ring body and pipe portion perpendicular.
