Abstract
The utility model discloses a novel center split pipe hoop, comprising two semicircular plastic pipe hoop bodies corresponding to pipe joints; wherein, one end of the pipe hoop body is provided with a fastening groove, the other end of the pipe hoop body is provided with a fastener matched with the fastening groove; the two semicircular pipe hoop bodies are fastened with each other to form a circular pipe hoop; an inserting end of the fastener for being inserted into the fastening groove is provided with an inserting chamfer; and a lower end face of the fastener at a rear end of the inserting chamfer and fastened with the fastening groove is an inclined plane. By adopting the structure of the novel center split pipe hoop of the utility model, when the two semicircular pipe hoop bodies are fastened, as the lower end face of the fastener at the rear end of the inserting chamfer and fastened with the fastening groove is the inclined plane, the inclined plane is abutted against a lower end face of the fastening groove, the inserting chamfer is not easy to drop from the fastening groove, so that the fastener and the fastening groove are fixed firmly and can not be separated by using a hand, in this way, there is no need to provide a bolt for performing fixation again, therefore, the novel center split pipe hoop has the advantages of simpler structure, convenient production, and reduced cost. In addition, when a failure occurs on a pipeline, the pipe hoop can be pried up by using a tool such as a screwdriver, thus the pipeline can be maintained conveniently.
Description
Technical field
The utility model relates to a kind of pipeline connecting device, relates in particular to a kind of novel opposite opened pipe collar of connecting pipeline.
Background technique
The opposite opened pipe collar of extensive use at present generally comprise two semicirculars in shape with the corresponding plastic tube hoop body of pipe joint, two semicircular pipe band body fixed tube joint that is interlocked.Pipe band body one end is provided with catching groove, and the other end is provided with the fastener that matches with catching groove, after the catching groove of this ordinary construction and fastener fasten; Fastener is prone to from catching groove, deviate from; Manually can open,, also bolt hole need be set so two catching grooves and corresponding fastener not only need be set on the pipe band body.After two semicircular pipe band body fasten, also need further to fix with bolt.When pipeline breaks down, the bolt of need outwarding winding earlier, maintenance is trouble extremely.Simultaneously, such pipe collar structure is difficult for processing, and cost of production is high.
Summary of the invention
In order to overcome the deficiency of existing technology, the purpose of the utility model provides a kind of simple in structure, the novel opposite opened pipe collar that is connected firmly.
A kind of novel opposite opened pipe collar of the utility model; Comprise two semicircular and corresponding plastic tube hoop bodies of pipe joint; Pipe band body one end is provided with catching groove, and the other end is provided with the fastener that matches with catching groove, and the fastener of two semicircular pipe band body and catching groove fasten conglobate pipe collar each other; The insertion end that said fastener inserts catching groove is provided with the insertion chamfering, and fastener is the plane of inclination inserting the lower end surface that chamfering rear end and catching groove be interlocked.
The angle of inclination of said plane of inclination is the 1-3 degree.
Adopt the structure of the utility model, when two semicircular pipe band body are interlocked, because of fastener is the plane of inclination inserting the lower end surface that chamfering rear end and catching groove be interlocked; This plane of inclination props up the catching groove lower end surface, inserts chamfering and is difficult for from catching groove, deviating from, so fastener and catching groove fixedly secure; Can't open with hand, need not to be provided with bolt like this and fix again, make the structure of pipe collar simpler; Convenient for production, cost reduces.When pipeline breaks down, but tamper tool pipe collars such as screw-driver are easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the semicircular pipe band body of the utility model;
The structural representation that Fig. 2 analyses and observe for the part of the utility model opposite opened pipe collar;
Fig. 3 is the partial enlarged drawing of Fig. 2.
Embodiment
Shown in one of Fig. 1-3; A kind of novel opposite opened pipe collar of the utility model comprises two semicircular and corresponding plastic tube hoop bodies 1 of pipe joint, and pipe band body 1 one ends are provided with catching groove 2; The other end is provided with the fastener 3 that matches with catching groove 2; The fastener 3 of two semicircular pipe band body 1 fastens conglobate pipe collar each other with catching groove 2, and the insertion end that said fastener 3 inserts catching grooves 2 is provided with inserts chamfering 4, and fastener 3 is the plane of inclination inserting chamfering 4 rear ends with the lower end surface 5 that catching groove 2 is interlocked.
Adopt above structure, when two semicircular pipe band body 1 were interlocked, the insertion chamfering 4 of one of them semicircular pipe hoop body 11 1 end hook button 3 buckled in the catching groove 2 of another semicircular pipe hoop body 12; Because of fastener 3 is the plane of inclination with the lower end surface 5 that catching groove 2 is interlocked inserting chamfering 4 rear ends, this plane of inclination 5 is against catching groove 2 lower end surfaces, hook on the fastener is up moved be stuck in the catching groove; Inserting chamfering 4 is difficult for from catching groove 2, deviating from; So fastener 3 fixedly secures with catching groove 2, can't open the fastener 3 that only a catching groove 2 need be set and match on the pipe band body like this with hand; Need not that also bolt is set fixes again; Make the structure of pipe collar simpler, convenient for production, cost reduces.When pipeline breaks down, but tamper tool pipe collars such as screw-driver are easy to maintenance.
The angle of inclination of said plane of inclination 5 is the 1-3 degree.
Claims (2)
1. novel opposite opened pipe collar; Comprise two semicircular and corresponding plastic tube hoop bodies of pipe joint; Pipe band body one end is provided with catching groove, and the other end is provided with the fastener that matches with catching groove, and the fastener of two semicircular pipe band body and catching groove fasten conglobate pipe collar each other; It is characterized in that: the insertion end that said fastener inserts catching groove is provided with the insertion chamfering, and fastener is the plane of inclination inserting the lower end surface that chamfering rear end and catching groove be interlocked.
