Description

Technical Field

[0001] The utility model relates to the technical field related to pipeline connection, in particular to a combined pipeline connector. Background Art

[0002] The existing pipeline connections on the market are generally used in actual environments. The pipelines are connected to each other according to the actual use environment to achieve the effect of liquid or gas transmission. When the pipelines on the market are connected to each other, the top ends of the two connected pipelines are only threadedly connected to the threaded structure that penetrates the inner wall of the pipeline through a through-pipe to achieve the connection effect. However, in the actual use environment, when the two pipelines need to be connected, their positions are often not all on the same horizontal line. Therefore, when the traditional pipeline connector is connected, its angle cannot be flexibly adjusted according to the position of the external pipeline, resulting in the use range of the entire connector being too limited. Utility Model Content

[0003] The purpose of the utility model is to provide a combined pipe connector to solve the problem that the pipe connectors currently on the market, as mentioned in the background art, are often not located on the same horizontal line when two pipes need to be connected in actual use environments. As a result, when connecting, the traditional pipe connectors often cannot flexibly adjust their angles according to the positions of external pipes, resulting in the problem that the use range of the entire connector is too limited.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined pipe connector, including two connecting pipes, the top ends of which are arranged in a threaded structure;

[0005] The connecting hose is made of PVC and is hot-melt connected between the two connecting pipes. The connecting hose can be compressed and extended.

[0006] Also includes:

[0007] The limiting mechanism is arranged at an external position of the connecting hose.

[0008] Preferably, the connecting hose can be bent when being compressed and extended, and the bending connecting hose is angle-limited by a limiting mechanism.

[0009] Preferably, the pipe connector also includes a fastening mechanism, which is respectively provided at the top of both sides of the limiting mechanism and is used to fix the position of the limiting mechanism.

[0010] Preferably, two of the fastening mechanisms are symmetrically arranged, and the fastening mechanism comprises a fastening ring which is arranged in a semicircular structure, and mounting blocks are integrally installed at the top ends of both sides of the fastening ring;

[0011] A through hole is arranged in the middle of the mounting block, a screw rod may be arranged inside the through hole, and the outside of the screw rod is fastened by a fastening bolt.

[0012] Preferably, the limiting mechanism comprises:

[0013] The mounting groove is inlaid at equal angles on the inner and outer walls of the connecting pipe, and its cross section is arranged in a "U"-shaped structure, and a limit rod is engaged inside it;

[0014] The light angles of the limit rods are distributed outside the connecting hose.

[0015] Preferably, the connecting hose is made of soft metal, and the top ends of both sides of the limiting rod are fixed by fastening mechanisms.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the combined pipe connector changes the traditional through-connecting pipe into a connecting hose arranged in the middle of the connecting pipe, and the connecting hose can be bent so that the positions of the top ends of both sides of the connecting pipe can be flexibly changed, thereby making it possible to flexibly adjust according to different actual usage conditions, thereby ensuring a wider range of use of the entire connecting pipe;

[0017] A limiting mechanism is also provided, which can fix the angle of the connecting hose after being bent, and it can also be tightened by the tendon mechanism, thereby ensuring that the angle of the entire connecting piece can be fixed after the angle change is completed, ensuring that the entire pipeline can perform continuous and efficient pipeline connection work.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 , the utility model provides a technical solution: a combined pipe connector, including a connecting pipe 1, which is provided with two, and the top end of the inner part is provided with a threaded structure;

[0025] The connecting hose 2 is made of PVC and is hot-melt connected in the middle of the two connecting pipes 1, and the connecting hose 2 can be compressed and extended;

[0026] Also includes:

[0027] The limiting mechanism 4 is arranged at an external position of the connecting hose 2 .

[0028] The connecting hose 2 can be bent when being compressed and extended, and the angle of the bent connecting hose 2 is limited by the limiting mechanism 4 .

[0029] The pipeline connector also includes a fastening mechanism 3 , which is respectively arranged at the top of both sides of the limiting mechanism 4 and is used to fix the position of the limiting mechanism 4 .

[0030] Two fastening mechanisms 3 are symmetrically arranged, and the fastening mechanism 3 includes a fastening ring 31, which is arranged in a semicircular structure, and mounting blocks 32 are integrally installed on the top of both sides of the fastening ring 31;

[0031] A through hole 33 is provided in the middle of the mounting block 32, a screw rod may be provided inside the through hole 33, and the outside of the screw rod is fastened by a fastening bolt 34;

[0032] Specifically, the position of the limiting mechanism 4 can be fixed by the fastening mechanism 3 , thereby ensuring that the connecting hose 2 , after being limited by the limiting mechanism 4 , can be adjusted stably in angle.

[0033] The limiting mechanism 4 comprises:

[0034] The mounting groove 42 is embedded at equal angles on the inner and outer walls of the connecting pipe 1, and its cross section is arranged in a "U"-shaped structure, and the limiting rod 41 is engaged therein;

[0035] The light angle of the limiting rod 41 is distributed outside the connecting hose 2 .

[0036] The connecting hose 2 is made of soft metal, and the top ends of both sides of the limit rod 41 are fixed by the fastening mechanism 3;

[0037] Specifically, the limiting rod 41 can be bent according to the bending angle of the connecting hose 2, thereby achieving the effect of fixing the position of the bent connecting hose 2.

[0038] Working principle: When using the combined pipe connector, when connecting the pipes in the actual use environment through the entire connector, when there is a certain position offset between the two external pipes, at this time, the two connecting pipes 1 can be controlled to perform a certain position offset under the action of the connecting hose 2. After the offset is completed, the limit rod 41 can be controlled to perform bending at the same angle. After the bending is completed, it is only necessary to respectively engage the bent limit rod 41 into the corresponding installation groove 42, thereby achieving the effect of limiting the angle of the connecting hose 2 after bending. After the limiting is completed, at this time, the staff only needs to engage the two fastening rings 31 at the upper and lower parts of the annular limiting mechanism 4 so that the two mounting blocks 32 on the two fastening rings 31 correspond to each other. After the correspondence is completed, the control screw passes through the through hole 33 on the mounting block 32, and finally, it is fixed by the fastening bolt 34, thereby achieving the effect of bending the angle of the connecting pipe 1 at the two top ends of the connecting piece, which is convenient for flexible installation according to actual actual conditions.
