Description

Technical Field

[0001] The utility model relates to the technical field of water pipe maintenance and cutting, in particular to a device used for PPR water pipe maintenance and cutting. Background Art

[0002] In daily life, water pipes are generally connected with pipe joints. PPR hot-melt pipes are also widely used water pipes. The existing water pipe joints include straight joints, bent joints, tee joints and union joints. The common PPR water pipe diameters on the market are 25mm (also known as 6-way pipes) and 20mm (commonly known as 4-way pipes). PPR water pipes are divided into hot water pipes and cold water pipes. Generally, the wall thickness of hot water pipes is 1-2mm thicker than that of cold water pipes. The general specifications are marked on the pipes.

[0003] The PPR water pipe repair and cutting devices currently sold on the market do not have the function of rapid cutting and repair when repairing PPR pipes, and cannot cut and quickly repair PPR water pipes; the repairman can only cut off the whole or part of the water pipe, and then reinstall the whole water pipe with hot melt, which affects efficiency and wastes materials, and goes against the spirit of saving. Therefore, it is necessary to design a new device to meet the actual use needs of repairing PPR pipes. In view of this, we propose a device for PPR water pipe repair and cutting.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for PPR water pipe maintenance and cutting, comprising a lead head, a lead wing, a lead handle, and a lead tail, wherein a cutting head device is arranged on one end of the lead head, and the other end is connected to the lead wing, and the lead wing is below the cutting head device;

[0007] Preferably, the cutting head device is a convex head in the shape of a "convex" character located in front of the lead head, with cutting edges provided on the left and right sides of the convex head, and a lead wing provided below the convex head;

[0008] Preferably, the cutting head device is a "cross" shaped twist head located in front of the lead head, with cutting edges provided on four sides of the twist head and lead wings provided below the twist head;

[0009] Preferably, the cutting edges on the left and right sides of the convex head are symmetrical to each other;

[0010] Preferably, the cutting edges on four sides of the twist head are parallel to each other;

[0011] Preferably, the lead wing is symmetrical on the left and right sides, and a cutting edge is provided at the wing corner;

[0012] Preferably, the lead handle is a telescopic device that is movably connected;

[0013] Preferably, the specification size of the lead head is 160 or 110 or 90 or 75 or 63 or 50 or 40 or 32 or 25 or 20 mm.

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

[0015] The cutting lead head used for repairing PPR pipes is made of a whole metal rod. The lead head cutting head device has a cutting surface, which is convenient for quickly cleaning the inside of the water pipe joint; the lead wing has a positioning function, and can adjust the internal cutting distance according to the size of the water pipe joint.

[0016] The lead head formed by the cutting head device and the lead wing is integrated, which has the advantages of simple structure and easy operation. When in use, the lead head is fixed on the electric drill and cut at the damaged PPR pipe. During cutting, the cutting material is directly discharged through the gaps on both sides of the lead head, avoiding pollution to the inside of the water pipe and reducing secondary cleaning.

[0017] One end where the lead handle is connected to the lead tail is provided with a movable connection with a telescopic device, and the distance can be appropriately adjusted according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1

[0027] See also Figure 1-Figure 2 As shown, the PPR water pipe repair and cutting device of this embodiment is formed by processing a whole metal rod, including a lead head 1, a lead wing 2, a lead handle 3, and a lead tail 4. A cutting head device is arranged on one end of the lead head 1, and the other end is connected to the lead wing 2. The lead wing 2 is below the cutting head device. When in use, the cutting head device is located at the front of the lead head 1, and a convex head 12 in the shape of a "convex" character is provided. Cutting edges 11 are arranged on both sides of the convex head 12. First, find the broken or damaged water pipe, find the water pipe joint closest to the broken or damaged water pipe, and then cut off the broken or damaged water pipe along the position close to the water pipe joint. The broken water pipe, then insert the convex head 12 into the water pipe joint, use the positioning function of the lead wing 2, according to actual needs, insert the convex head 12 to the appropriate position, and then start the tool, the convex head 12 starts to work, the convex head 12 rotates along the inner wall of the water pipe, and the water pipe remaining on the inner wall of the water pipe joint is cleaned with the cutting edges 11 on both sides of the convex head 12. The cleaned water pipe residue flows out through the gap of the convex corner of the cutting head device until it is clean, and then it is hot-melted again and connected to the water pipe. At the same time, the lead handle 3 is a telescopic device with a movable connection, which is convenient for the maintenance master to adjust the distance according to actual use needs.

[0028] Example 2

[0029] See also Figure 3 As shown, when the PPR water pipe repair and cutting device of this embodiment is in use, the cutting head device is located at the front part of the lead head 1, and is a "cross" shaped twist head 13. Cutting edges 11 are provided on the four sides of the twist head 13. The broken or damaged water pipe is found, and the water pipe joint closest to the rupture or damage is found. Then, the broken or damaged water pipe is cut off along the position close to the water pipe joint, and then the "cross" shaped twist head 13 is inserted into the water pipe head. The positioning effect of the lead wing 2 is utilized. According to actual needs, the twist head is inserted into the appropriate position, and then the tool is started, and the twist head starts to work. The twist head 13 rotates along the inner wall of the water pipe, and the water pipe remaining on the inner wall of the water pipe joint is cleaned up by the cutting edges 11 on the four sides of the twist head. The cleaned water pipe residue flows out through the gaps on the four sides of the twist head 13 until it is cleaned, and then it is re-heat-melted and connected to the water pipe. At the same time, the lead handle 3 is a telescopic device with a movable connection, which is convenient for the maintenance master to adjust the distance according to actual use needs.
