[0035] like Figures 1 to 10 As shown;

[0036] An installation device for a coupling sealing ring includes a base 1 and an installation mechanism 2 disposed on the surface of the base 1;

The movable gripper 216 has a push-away groove 224 inside, and the through hole 221 is connected to the second slot 2110 through the push-away groove 224. The push-away plate 223 is inserted inside the push-away groove 224, and the push-away plate 223 and the movable gripper 216 are slidably connected. One end of the push-away plate 223 and the linkage rod 222 are fixedly connected.

[0042] In an optional embodiment, a first ring sleeve 226 is fitted on the surface of the movable gripper 216, the first ring sleeve 226 and the movable gripper 216 are slidably connected, and the first ring sleeve 226 and the end of the linkage rod 222 away from the push plate 223 are fixedly connected.

[0043] In an optional embodiment, a second spring 225 and a first connecting plate 227 are provided between the linkage rod 222 and the movable gripper 216.

[0044] In an optional embodiment, the extrusion assembly 23 includes a second connecting plate 232, a semi-column push rod 233, and a third spring 235. Two second connecting plates 232 are symmetrically arranged above the base 1. The semi-column push rod 233 is fixedly connected to one end of each of the two second connecting plates 232 that is far apart from each other. A third spring 235 is arranged between the second connecting plate 232 and the base 1. The two ends of the third spring 235 are fixedly connected to the second connecting plate 232 and the base 1, respectively.

[0045] In an optional embodiment, the first column 212 and the second column 213 are both provided with a half-column push groove 234. The half-column push groove 234 is connected to the first slot 219. The half-column push rod 233 is inserted into the half-column push groove 234. The two half-column push rods 233 are slidably connected to the first column 212 and the second column 213 respectively.

[0046] In an optional embodiment, the second connecting plate 232 has an L-shaped structure, and a second ring 231 is provided at one adjacent end of the two second connecting plates 232. The second ring 231 is fixedly connected to the two second connecting plates 232, and the second ring 231 is sleeved on the surface of the fixed handle 211. The second ring 231 and the fixed handle 211 are slidably connected.

[0047] It should be noted that: the first column 212 and the second column 213 are respectively installed at a diameter of 83mm on the base 1, which is smaller than the diameter of the inner sealing groove of the coupling (84mm). The sealing ring is 3mm thick. A movable slot 218 with a width of 3mm and a length of 50mm is opened on the vertical line of the base 1 perpendicular to the midline of the first column 212 and the second column 213 to facilitate the movement of the movable claw 216. Under the elastic potential energy of the first spring 215, the movable claw 216 is reset after movement. The movable claw 216 changes the shape of the sealing ring, thereby facilitating the installation of the sealing ring.

[0048] It should be noted that the second connecting plate 232 has an L-shaped structure, which avoids obstructing the movable slot 218 and ensures the movement range of the movable gripper 216. The surfaces of the second ring 231 and the fixed handle 211 are in contact, so that the two semi-column push rods 233 move synchronously.

[0049] It should be noted that when no force is applied to the first ring 226, the elastic potential energy of the second spring 225 causes the linkage rod 222 to move the push plate 223, allowing the push plate 223 to slide into the push groove 224 for future use. The shapes of the movable gripper 216 and the linkage rod 222 are as follows: Figure 5 and Figure 6 As shown, the push plate 223 can be moved and reset under the action of the second spring 225.

[0050] Working principle: The sealing ring is secured inside the two first slots 219 and the second slot 2110. The first slots 219 on the second column 213 and the first column 212 support the sealing ring outwards. The movable slot 218 allows the movable block 217 to slide on the surface of the base 1. Pulling the movable jaw 216 pulls the sealing ring. The movement of the movable jaw 216 stretches the first spring 215, thus positioning the sealing ring correctly. Then, the handle on the movable jaw 216 moves the sealing ring inward to the appropriate position. The operator then places the protruding part of the sealing ring into the sealing groove of the coupling and releases the handle of the movable jaw 216. The movable jaw 216 rebounds under the elastic potential energy of the first spring 215, thus... The sealing ring is pushed into the coupling sealing groove, and then the device is removed. The sealing ring installation is complete. By pulling the movable jaw 216, the shape of the sealing ring is changed, so that the sealing ring is pushed into the coupling sealing groove, and then the device is removed, thereby realizing the installation of the sealing ring and improving the convenience of sealing ring installation. When the sealing ring is installed inside the first slot 219, the second ring 231 is pulled away from the base 1. The movement of the second ring 231 drives the half-column push rod 233 to slide inside the half-column push groove 234 through the second connecting plate 232. At this time, the third spring 235 is in a stretched state. When the sealing ring is placed in the first slots 219 respectively opened on the surfaces of the first column 212 and the second column 213, the second ring 231 is released. The applied force, under the elastic potential energy of the third spring 235, causes the two semi-column push rods 233 to slide inside the first column 212 and the second column 213 respectively, until the two semi-column push rods 233 respectively press the sealing ring inside the first slot 219, thereby fixing the sealing ring inside the first column 212 and the second column 213. When it is necessary to push the sealing ring into the coupling sealing groove, a force is applied to the second ring sleeve 231 in a direction away from the base 1, thereby releasing the compression limit of the semi-column push rods 233 on the sealing ring, thus allowing the sealing ring to be pushed into the coupling sealing groove. This helps to fix the sealing ring inside the first column 212 and the second column 213, preventing the sealing ring from slipping out of the first column 212 and the second column 213 when the sealing ring is deformed. The inner part of the slot 219 slides out. Under the action of the elastic potential energy of the second spring 225, the push-away plate 223 is located inside the push-away groove 224. When the sealing ring is pushed into the coupling sealing groove and the device is removed, the sealing ring is located inside the second slot 2110. Under the action of the elastic force, the sealing ring is not easy to slide out from the inside of the second slot 2110. A force is applied to the first ring sleeve 226 in the direction of the base 1. The movement of the first ring sleeve 226 drives the linkage rod 222 to move. The linkage rod 222 slides inside the through hole 221, thereby driving the push-away plate 223 to slide inside the push-away groove 224. As the push-away plate 223 slides towards the inside of the second slot 2110, the sealing ring inside the second slot 2110 can be pushed out.This design facilitates the push-off plate 223 in pushing the sealing ring out from inside the second slot 2110, preventing misalignment of the sealing ring due to difficulty in removing it from inside the movable gripper 216, thereby improving the efficiency of sealing ring installation.

[0051] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
