In the later maintenance of the garden, it is necessary to supply nutrients through drip irrigation pipes.

[0003] The existing drip irrigation pipes require a connecting pipe to be inserted into two drip irrigation pipes during installation, and then the pipes are tied together with wire. This connection method is slow to install and has low efficiency. In addition, leaks are likely to occur at the connection points after installation, resulting in water waste. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a drip irrigation pipe connection mechanism for landscaping.

[0005] The technical solution of this utility model to achieve the above objectives is a drip irrigation pipe connection mechanism for landscaping, comprising: a main pipe, and further comprising:

[0006] The socket tubes are installed at both ends of the main tube. Their inner diameter is the same as that of the main tube, and their outer diameter is smaller than that of the main tube.

[0007] The fixing nut is installed at both ends of the center of the main tube and is fitted onto the socket tube with its opening facing the socket tube. The nut is equipped with a positioning cone inside the socket tube and is fitted onto the socket tube. Several positioning cones are evenly distributed on its inner surface.

[0008] A conical rubber plug is fitted onto the socket tube and is located on one side of the positioning cone, making movable contact with the positioning cone;

[0009] An annular clamping screw head is fitted onto the socket tube and threaded into the fixing nut. One end of the head has a tapered flare, and the other end has an arc-shaped chamfer.

[0010] An annular compression pad is set inside the annular clamping screw head and located within the conical flare.

[0011] The drip irrigation pipes are installed on both sides of the main pipe and fitted onto the socket pipe and the conical rubber plug. Positioning tube segments are cut out at the ends of the pipes, and the positioning tube segments are evenly distributed and embedded inside the fixing nuts.

[0012] In this invention, after the annular clamping screw head is installed into the fixing nut, it clamps the positioning tube piece, fixing it between the annular clamping screw head and the fixing nut.

[0013] In this invention, after the positioning tube is installed between the annular clamping screw head and the fixing nut, the positioning cone is inserted into the positioning tube to fix it.

[0014] In this invention, the conical flare of the annular clamping screw head corresponds to the shape of the positioning cone and the cone rubber plug.

[0015] In this invention, after the annular clamping screw head is installed inside the fixing nut, the annular clamping screw head squeezes the annular compression pad, thereby squeezing and sealing the drip irrigation pipe.

[0016] In this invention, the outer diameter of the socket tube is larger than the inner diameter of the drip irrigation pipe.

[0017] In this invention, one end of the socket tube is provided with a socket chamfer.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a technical solution, such as Figures 1-5 As shown; a drip irrigation pipe connection mechanism for landscaping includes: a main pipe 1, and a socket pipe 2, installed at both ends of the main pipe 1, with an inner diameter the same as the main pipe 1 and an outer diameter smaller than the main pipe 1; a fixing nut 3, installed at both ends of the center of the main pipe 1 and fitted onto the socket pipe 2, with its opening facing the socket pipe 2, and a positioning cone 31 is provided inside the nut 31, which is fitted onto the socket pipe 2, and a plurality of positioning cones 32 are provided on its inner surface, which are evenly distributed; and a cone rubber plug 4, fitted onto the socket pipe 2, located on one side of the positioning cone 31, and in movable contact with the positioning cone 31.

[0031] In this embodiment of the invention, the main tube 1 and the socket tube 2 have the same inner diameter, which facilitates water transportation and reduces transportation resistance. The outer diameter of the main tube 1 is larger than that of the socket tube 2, which makes the wall thickness of the main tube 1 greater, thereby ensuring the strength of the main tube 1, preventing it from breaking, and improving its service life.

[0032] In this embodiment of the utility model, by utilizing the contact fit between the positioning cone 31 and the conical rubber plug 4, after the drip irrigation pipe 7 is fitted onto the positioning cone 31 and the conical rubber plug 4, the positioning cone 31 and the conical rubber plug 4 can be used to open up the drip irrigation pipe 7, and then the drip irrigation pipe 7 can be used to squeeze the conical rubber plug 4 to ensure the airtightness of the installation of the drip irrigation pipe 7.

[0033] In this embodiment of the utility model, the positioning cone 32 provided inside the fixing nut 3 allows the worker to pre-cut the end of the drip irrigation pipe 7 when connecting it, so that after installation, the positioning piece 71 cut at the end of the drip irrigation pipe 7 can be embedded in the positioning cone 32, thereby ensuring the stability of the connection of the drip irrigation pipe 7 by using the limiting of the positioning cone 32.

[0034] In this invention, the outer diameter of the socket tube 2 is larger than the inner diameter of the drip irrigation pipe 7, and a socket chamfer is provided at one end of the socket tube 2.

[0035] In this embodiment of the invention, the socket tube 2 is inserted into the drip irrigation pipe 7, which can open the drip irrigation pipe 7. Then, the tightness of the connection between the socket tube 2 and the drip irrigation pipe 7 is used to ensure the airtightness of the drip irrigation pipe 7 installation.

[0036] In this embodiment of the invention, the chamfered socket at the end of the socket tube 2 facilitates the insertion of the drip irrigation pipe 7, thereby improving installation efficiency.

[0037] An annular compression screw head 5 is fitted onto the socket tube 2 and threaded into the fixing nut 3. One end of the screw head has a tapered flare 51, and the other end has an arc-shaped chamfer 52. An annular compression pad 6 is placed inside the annular compression screw head 5 and located inside the tapered flare 51. Drip irrigation pipes 7 are placed on both sides of the main pipe 1 and fitted onto the socket tube 2 and the conical rubber plug 4. Positioning tube pieces 71 are cut out at the ends of the pipes. The positioning tube pieces 71 are evenly distributed and embedded inside the fixing nut 3.

[0038] In this embodiment of the utility model, the end of the drip irrigation pipe 7 is cut to cut out a positioning tube piece 71. Then, the positioning tube piece 71 is flipped outward to make it perpendicular to the drip irrigation pipe 7, so that the positioning tube piece 71 can be embedded in the fixing nut 3, thereby ensuring the firmness of the installation of the drip irrigation pipe 7.

[0039] In this embodiment of the utility model, the annular clamping screw head 5 is installed on the fixing nut 3, which can squeeze the positioning tube piece 71 at the end of the drip irrigation pipe 7. On the one hand, the squeezing of the annular clamping screw head 5 and the fixing nut 3 ensures the firmness of the installation of the drip irrigation pipe 7. On the other hand, the positioning cone 32 limits the installation, which further ensures the firmness of the installation of the drip irrigation pipe 7.

[0040] In this embodiment of the utility model, the arc-shaped chamfer 52 inside the annular clamping screw head 5 facilitates the dragging of the drip irrigation pipe 7 by the staff, reduces the wear of the drip irrigation pipe 7, ensures its integrity, and improves its service life.

[0041] In this invention, the conical flared end 51 of the annular clamping screw head 5 corresponds to the shape of the positioning cone 31 and the conical rubber plug 4.

[0042] In this embodiment of the invention, the conical flare 51 inside the annular clamping screw head 5 allows the annular clamping screw head 5 to be sealed to the outer surface of the drip irrigation pipe 7 by squeezing the conical rubber plug 4 after installation. The sealing effect of the drip irrigation pipe 7 is ensured by the sealing of the conical rubber plug 4 and the insertion sealing of the socket tube 2, thus avoiding water leakage.

[0043] When using this utility model, firstly, the staff puts the annular clamping screw head 5 onto the two drip irrigation pipes 7 respectively. Then, the staff cuts the ends of the two drip irrigation pipes 7 that need to be connected by using scissors, and cuts out a number of evenly distributed positioning tube pieces 71 at the ends. Then, by bending them outward, the positioning tube pieces 71 are made perpendicular to the drip irrigation pipes 7.

[0044] Subsequently, the staff took out the main tube 1 and inserted the socket tube 2 at one end into one of the drip irrigation pipes 7, so that the drip irrigation pipe 7 was fitted onto the socket tube 2. Then, the staff continued to push the main tube 2, so that the socket tube 2 was inserted further and the drip irrigation pipe 7 was fitted onto the cone rubber plug 4 and the positioning cone 31. At this time, the socket tube 2 was inserted into the drip irrigation pipe 7.

[0045] Subsequently, the staff moved the annular clamping screw head 5 closer to the fixing nut 3, and gradually installed it into the fixing nut 3 by rotating the annular clamping screw head 5 and tightening it. As the annular clamping screw head 5 gradually tightened, it squeezed the positioning tube piece 71, fixing it between the annular clamping screw head 5 and the fixing nut 3. At the same time, the positioning tube piece 71 was embedded in the positioning cone 32. Thus, by using double fixation, the drip irrigation pipe 7 was fixed to one side of the main pipe 1.

[0046] When the annular compression screw head 5 is tightened, the main body tube 1 is connected to one of the drip irrigation pipes 7. The drip irrigation pipe 7 is opened by the socket tube 2, and the sealing of the cone rubber plug 4 and the annular compression soft pad 6 makes the drip irrigation pipe 7 and the main body tube 1 in a sealed state.

[0047] Subsequently, the staff can use the above method to insert another socket pipe 2 on the main pipe 1 into another drip irrigation pipe 7, and complete the connection between the main pipe 1 and the other drip irrigation pipe 7 by installing the annular clamping screw head 5.

[0048] In actual production, the shape of the main tube 1 can be set to a straight tube, a conventional tee, a Y-angle tee, a cross four-way, etc., according to actual usage requirements, to meet actual usage needs.

[0049] During the installation of this connection mechanism, when the socket tube 2 is inserted into the drip irrigation pipe 7, the drip irrigation pipe 7 can be preheated with hot water to improve the flexibility and elasticity of the drip irrigation pipe 7, thereby facilitating the insertion of the socket tube 2.
