[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] See also Figure 1-4 The present invention provides a technical solution: a tool for an automatic reset metal pipe sleeve sealing ring, comprising:

[0034] A guide mandrel 1, wherein a sleeve 2 is provided on the guide mandrel 1;

[0035] A shaft sleeve 3, wherein the shaft sleeve 3 is sleeved on the sleeve 2, and a sealing ring 4 is sleeved on the shaft sleeve 3, wherein a plurality of sealing rings 4 are arranged in a row along the axial direction of the shaft sleeve 3;

[0036] The claw assembly includes a mounting plate 5 and a claw 6. The mounting plate 5 is movably connected to the guide core shaft 1. The two ends of the mounting plate 5 are respectively movably connected to a claw 5. The shaft sleeve 3 is located between the two claws 5.

[0037] An elastic element 7 is provided on the guide core shaft 1, one end of which is connected to the sleeve 2, and the other end of which is connected to the mounting plate 5. When the mounting plate slides downward, the elastic element is compressed, and the claws push the sealing ring at the bottom of the shaft sleeve downward, separating it from the shaft sleeve. After installation is complete, the mounting plate is released, and the elastic element automatically resets the mounting plate.

[0038] The elastic element 7 is a spring. The elastic element can also be an elastic rubber block, which can also achieve the same effect as elasticity.

[0039] The guide core shaft 1 is provided with a thread, and the sleeve 2 is threadedly connected to the guide core shaft 1. The sleeve is connected by a thread, so that the position of the sleeve can be adjusted. The sleeve is a metal sleeve with small deformation, which can prevent the shaft outer sleeve from loosening. The specific sleeve is a copper sleeve.

[0040] The bottom of the guide mandrel 1 extends out of the bottom of the shaft sleeve 3. This facilitates inserting the guide mandrel into the metal tube and ensures that the metal tube is concentric with the tooling.

[0041] The bottom of the shaft sleeve 3 has an arc section 8, the diameter of which is larger than the inner diameter of the sealing ring 4 in a natural state, so as to prevent the sealing ring from falling off.

[0042] The arc section 8 is a structure that is thick in the middle and thin at both ends, so as to facilitate the sealing ring to exit the shaft sleeve.

[0043] The clamping claw 5 is hinged on the mounting plate 5. The clamping claw is an L-shaped plate body, which can be used to separate adjacent sealing rings.

[0044] A limit plate 9 is provided on the top of the guide core shaft 1, and the limit plate 9 is located above the mounting plate 5. This can prevent the mounting plate from sliding out of the guide core shaft.

[0045] Working principle: Through the setting of the shaft outer sleeve, the sealing ring is installed from the bottom of the shaft outer sleeve, so that multiple sealing rings can be installed in sequence. Since the shaft outer sleeve has an arc section, the diameter of the arc section is larger than the inner diameter of the sealing ring in its natural state, which can prevent the sealing ring from falling off the shaft outer sleeve by itself. When installing the sealing ring, insert the guide core shaft into the metal tube to ensure that the metal tube and the tooling are concentric. Hold the tooling with one hand and clamp the movable clamping jaw into the gap between the lowest sealing ring and the sealing ring above it. Push the movable clamping jaw downward to guide the sealing ring into the sealing groove of the metal tube. After the ring is completed, the spring will automatically reset the sealing tooling, and the sealing ring can be quickly inserted into the sealing groove of the metal tube, which can greatly improve production efficiency.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
