Technical Field
[0001] The utility model relates to the technical field of plastic joints, in particular to a water-leakage and crack-proof plastic joint copper insert. Background Art
[0002] A plastic joint is a plastic product used to connect pipes, fittings or other devices. It is usually made of plastic materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) or polyamide (PA). In order to increase the overall strength of the plastic joint or increase the function of the plastic joint, some copper inserts are often used inside.
[0003] The utility model with the existing authorization announcement number CN203963303U discloses a XX, which not only has T-shaped annular grooves on the inner and outer walls of the copper insert for fixedly combining with the joint covering layer, but also has an inwardly bent annular bend on the end face of the copper insert for fixedly combining with the joint covering layer, and an annular hook groove is provided on the back side of the annular bend, so that circumferential rotation and peeling between the copper insert and the joint covering layer can be prevented, and a firm connection between the copper insert and the joint covering layer can be achieved, which can effectively solve the peeling and cracking between the copper insert and the joint covering layer caused by leakage due to thermal expansion and contraction during the use of hot and cold water, and has good safety and reliability.
[0004] Although the above technical solution solves the peeling and cracking phenomenon between the copper insert and the joint covering layer caused by leakage due to thermal expansion and contraction during the use of hot and cold water to a certain extent, the above technical solution can only prevent cracking at the port of the plastic joint. It lacks an all-round reinforcement structure to prevent the plastic joint from cracking in all directions, resulting in a relatively general anti-cracking effect in the middle part of the plastic joint, which in turn makes the overall anti-cracking performance of the plastic joint defective.
[0005] Therefore, those skilled in the art provide a water-proof and crack-proof plastic joint copper insert to solve the problems raised in the above background technology. Utility Model Content

[0010] As a further solution of the utility model: the outer surface of each copper ring is fixedly connected to the inner wall of the plastic joint body, the inner wall of each damping ring is in contact with the outer surface of the copper head, both ends of each copper rod are fixedly connected to one end of the copper head close to the copper rod, the outer surface of the plastic joint body is fixedly connected to an anti-slip sleeve, and the outer surface of the anti-slip sleeve is fixedly connected to a plurality of identical anti-slip protrusions.
[0011] As a further solution of the utility model: the inner wall of the plastic joint body is fixedly connected to two threaded sleeves and two sealing washers respectively, and a side surface of each sealing washers close to the threaded sleeve is fixedly connected to the outer surface of the threaded sleeve.
[0012] As a further solution of the utility model: a waterproof gasket is arranged on the outside of each copper ring, and each waterproof gasket has four slots on a side close to the plastic joint body, and each waterproof gasket has a side close to the plastic joint body that contacts the outer surface of the copper ring and the outer surface of the plastic joint body respectively.
[0013] As a further solution of the utility model: four positioning posts are fixedly connected to a side surface of each copper ring away from the plastic joint body, and the outer surface of each positioning post is engaged with the inside of the slot.

The damping ring can increase the relative stability of the copper rod and the copper head in the plastic joint body. The hexagonal fastening head can conveniently cooperate with external tools to thread the threaded rod and the copper head, thereby allowing the top ring to tighten the copper ring. Therefore, the overall connectivity of the all-round reinforcement mechanism can enhance the anti-cracking performance of the middle part of the plastic joint body, play a role in comprehensively increasing the anti-cracking performance of the plastic joint body, and avoid the problem that the anti-cracking effect of the middle part of the plastic joint is relatively general due to the lack of an all-round reinforcement structure for all-round prevention of cracking of the plastic joint, thereby making the overall anti-cracking performance of the plastic joint defective.

By providing the threaded sleeve 5, a threadable structure can be added to the inside of the plastic joint body 1, thereby facilitating the connection between the plastic joint body 1 and the external pipe. By providing the sealing washers 6, the inner ring diameter of the sealing washers 6 is smaller than the inner ring diameter of the threaded sleeve 5, and then after the external pipe is threadedly connected to the threaded sleeve 5, the sealing washers 6 can increase the sealing of the threaded connection between the external pipe and the threaded sleeve 5, thereby enhancing the anti-leakage performance of the plastic joint body 1.
[0027] The inner wall of each copper head 203 is threadedly connected with a threaded rod 205, and a waterproof gasket 8 is arranged on the outer side of each copper ring 201.
