Abstract

The utility model discloses a kind of papery junction block of paper runner channel pipe, including main body (1) in a tubular form, carrier (2) is equipped with described main body (1) two ends, thread segment (3) is equipped with each described carrier (2), using the junction block of above structure, because main body two ends are provided with carrier, connected so paper runner channel pipe can be realized by junction block in this connection, pouring channel tube two ends need not be done to reducing processing, so that pouring channel tube processing is more convenient, it is more flexible in this connection, screw thread is additionally provided with the carrier of the junction block, coordinate with screwed paper runner channel pipe and play better seal effect, avoid the phenomenon of leakage, sealed also without adhesive tape is reused.

Description

A kind of papery junction block of paper runner channel pipe

Technical field

The utility model is related to the papery junction block of the junction block of pouring channel tube, especially paper runner channel pipe.

Background technology

Using ceramic pouring channel tube more than in traditional casting process, but ceramic pouring channel tube processed complex, it is not easy to operate, it is difficult Cutting, sealing is poor and weight is not readily transportable greatly, so occurring in that the paper runner channel pipe being made of paper pulp, quality now Gently, easy to operate, easily cutting, is reduced into sand risk good airproof performance, and intensity is high.Do not allow fragile, improvement reclaimed sand quality, subtract Few equipment attrition, energy-conserving and environment-protective.Inserting mode is used in traditional paper runner channel pipe connection, but is occurred in bell and spigot position The phenomenon of leakage, influence casting, so rubber belt sealing is used in pouring channel tube junction, and present pouring channel tube needs to make reducing Structure, i.e. the small mechanism of the big one end diameter of one end diameter connects inconvenient in practice.

Utility model content

Of the prior art not enough there is provided one kind is easy to connect in order to solve, the paper runner channel pipe of good sealing effect connects Head tube, the technical scheme that the utility model is used is：

A kind of papery junction block of paper runner channel pipe, including main body in a tubular form, are equipped with described main body two ends and hold Socket part, thread segment is equipped with each described carrier.

Described thread segment is in internal thread in carrier inwall in external screw thread in carrier outer wall.

Described thread segment wall thickness is identical.

Described main body medium position is provided with bulge loop.

Described bulge loop is recessed into main body.

Described bulge loop is thought to protrude outside main body.

Described carrier is isometrical.

Using the junction block of above structure, because main body two ends are provided with carrier, so paper runner channel pipe in this connection may be used Connected with being realized by junction block, it is not necessary to which reducing processing is done at pouring channel tube two ends so that pouring channel tube processing is more convenient, in connection In it is more flexible, be additionally provided with screw thread on the carrier of the junction block, with screwed paper runner channel pipe coordinate play preferably it is close Envelope is acted on, it is to avoid the phenomenon of leakage, it is not required that is reused adhesive tape and is sealed.

Brief description of the drawings

Fig. 2 is the utility model section view.

Fig. 3 is the utility model thread segment partial enlarged view.

Embodiment

Junction block as shown in Figure 1 includes main body 1, and the structure of main body 1 in a tubular form, carrier 2 is provided at both ends with main body 1, Section 3 is threaded on carrier 2, the thread segment 3 can be set to traditional internal thread or external screw thread, as shown in Figure 3 at this In embodiment the wall thickness of thread segment 3 equally thus the thread segment 3 is raised in external screw thread in the outer wall of carrier 2, be in the inwall of carrier 2 Internal thread is recessed, so pouring channel tube can be inserted to the undertaking of junction block according to the different of the size of running channel interface tube in this connection Portion 2 is threadedly coupled, or the carrier 2 of junction block is inserted in pouring channel tube is threadedly coupled, in the junction block main body 1 Medium position be provided with bulge loop 4, bulge loop 4 can be to cave inward to be formed, it is this be used for by pouring channel tube insert carrier 2 in company Form is connect, prevents junction block from moving left and right on pouring channel tube to be disconnected position；Also a kind of form is bulge loop 4 to outside main body 1 Protrusion is formed, and this structure is applied to be attached in the insertion pouring channel tube of carrier 2, and the same effect of bulge loop 4 is also spacing anti- Only move left and right and set.The junction block uses paper material, and light weight, cost is low, more flexible when connecting pouring channel tube, it Preceding pouring channel tube will set the structure of reducing, and the interface diameter difference at two ends could carry out socket connection, and use joint now Pouring channel tube can just be made straight tube by the structure of pipe, and this causes the processing of pouring channel tube to be also convenient for a lot, and be connected also cleverer It is living.The problem of sealing is solved using the connection of thread segment 3, it is to avoid sealed in bell and spigot position, made using other attaching means Obtain easier for installation.
