By arranging the positioning device and the limiting device, when butt joint fine adjustment is carried out on an external pipeline, the two sets of connecting handles can drive the inserting clamping shaft to move outwards, so that the fixing clamping ring can accurately slide outside the butt joint sleeve, and then the guide distance of the threaded rotating sleeve outside the butt joint sleeve is adjusted and controlled; and meanwhile, the two groups of insertion clamping shafts can be stably limited in the insertion clamping grooves under the reset of the spring clamping rings, so that locking operation is completed, and the adaptability and practicability of butt joint between the three-way connector and the pipeline are effectively improved.

Description

Technical Field

[0001] The utility model relates to the technical field of tee joint devices, in particular to a tee joint with an extension and positioning function. Background Technique

[0002] A tee joint is a pipe fitting mainly used to connect pipes, pipe fittings or pipelines together. It has three interfaces and can connect three pipes or pipe fittings at the same time. Tee joints have many advantages, such as strong corrosion resistance, high tensile strength, good impact resistance, high reliability, and long-term usability. Therefore, they are widely used in industries such as petroleum, chemical industry, electric power, paper making, metallurgy, heat, cold chain, machinery, and construction.

[0003] For example, the utility model patent disclosed with the publication number: CN206918517U, a tee joint, includes a tee pipe. The left and right ends of the tee pipe are respectively installed with a second connecting pipe and a first connecting pipe. A third groove is opened at the bottom end inside the second connecting pipe. Cross bars are installed at the upper and lower ends on the left side of the first connecting block. The cross bars are connected to the first spring seats through hollow rods. A retaining bar is installed on the left outer wall of the cross bars. A second groove is opened at the bottom end of the third groove. The cross bars are matched with the second groove through a fixing device. The fixing device includes a hollow cylinder, and the hollow cylinder is connected to the cross bars. This tee joint strengthens the filtration of water when connecting the water pipe through a filter screen, avoiding impurities in the water flowing through the tee joint to the outlet and causing poor filtration. The first compression is carried out through the fixing device and the first connecting block.

[0004] Although the above tee joint can perform a certain filtering operation on the water source, its external connection structure is fixedly arranged. When connecting rigid pipes, it is not convenient to finely adjust the connection part of the tee joint according to needs, reducing the practicability of the joint. Therefore, there is an urgent need for a tee joint with an extension and positioning function to solve the above existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tee joint with an extension and positioning function to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A tee joint with an extension and positioning function, including a tee joint for support, and thread guide sleeves are equidistantly arranged near the end of the side end face of the tee joint.

[0007] A docking device. There are three groups of the docking devices in total, and all three groups of the docking devices are threadedly connected inside the thread guide sleeves.

[0008] The positioning device is slidably clamped to the inner end face of the docking device, and limiting devices are symmetrically arranged near the rear of the inner end face of the positioning device.

[0009] Preferably, the positioning device includes a fixed clamping ring. Docking clamping grooves for limiting are symmetrically formed on the outer end face of the fixed clamping ring, and a threaded rotating sleeve is fixedly arranged at the center of the inner end face of the fixed clamping ring. Four groups of guiding sliders are equidistantly arranged on the inner end face of the fixed clamping ring.

[0010] Preferably, the limiting device includes a connecting handle. A spring clamping ring for guiding is fixedly arranged on the lower end face of the connecting handle, and a plugging clamping shaft is fixedly arranged at the center of the lower end face of the connecting handle.

[0011] Preferably, the docking device includes a docking sleeve. Four groups of guiding chutes are equidistantly formed on the outer end face of the docking sleeve, and eight groups of plugging clamping grooves are equidistantly formed on the inner end face of the guiding chutes. Four groups of fixed guiding grooves are equidistantly formed near the outside of the inner end face of the docking sleeve.

[0012] Preferably, the guiding sliders are adapted to the guiding chutes, and the positioning device is slidably clamped to the outer end face of the docking sleeve through the adaptation of the guiding sliders to the guiding chutes. The stability of the four groups of guiding sliders sliding and limiting in the guiding chutes can effectively improve the stability of the threaded rotating sleeve sliding and guiding outside the docking sleeve.

[0013] Preferably, the connecting handle is fixedly arranged at the bottom of the docking clamping groove through the spring clamping ring. The plugging clamping shaft is adapted to the plugging clamping groove, and the plugging clamping shaft is fixedly clamped inside the docking sleeve through the plugging clamping groove. The spring clamping ring can provide sufficient guiding space for the plugging clamping shaft, so that the plugging clamping shaft can be stably locked inside the plugging clamping groove, improving the stability of the limit between the threaded rotating sleeve and the docking sleeve.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By setting the positioning device and the limiting device, when fine-tuning the docking of the external pipeline, the two groups of connecting handles can drive the plugging clamping shaft to move outwards, so that the fixed clamping ring can accurately slide outside the docking sleeve, thereby regulating the guiding distance of the threaded rotating sleeve outside the docking sleeve. At the same time, the two groups of plugging clamping shafts can be stably limited inside the plugging clamping grooves under the reset of the spring clamping ring, thereby completing the locking operation, effectively improving the adaptability and practicability of the three-way joint docking with the pipeline.
