As shown in fig. 1 to 3, the present embodiment discloses a seal ring assembling apparatus 100, the seal ring assembling apparatus 100 including an outer sleeve 10 and a pull rod 30, the outer sleeve 10 extending in a first direction. The pull rod 30 also extends along the first direction and is reciprocatingly movably sleeved in the outer sleeve 10, two end portions of the pull rod 30 respectively extend out of the outer sleeve 10, one end portion is an operating portion 311, the other end portion is a main body 32, and the main body 32 has a receiving groove 322 for receiving the seal ring 300.

The operation unit 311 functions to: the pull rod 30 is convenient for an operator to manually pull or push. If the entire mounting process is done by mechanical drive, the operating portion 311 is used to interface with a drive mechanism that drives the pull rod 30 to move relative to the outer sleeve 10.

The present embodiment will explain the seal ring assembling apparatus 100 of the present embodiment by taking as an example the installation of the seal ring 300 into the ring groove 220 of the deep hole 210 of the valve body 200 as shown in fig. 7.

As shown in fig. 1 and 5, the sealing ring 300 is first fitted over the main body 32 of the drawbar 30 in the horizontal position, such that the sealing ring 300 is located in the receiving groove 322, and the sealing ring 300 is hung on the bottom of the receiving groove 322 under its own weight. Pulling the handle 311 to the left causes the seal ring 300 to retract at least partially into the inner cavity of the outer sleeve 10. As shown in fig. 8, the angle of the seal ring assembling apparatus 100 is then moved and adjusted to feed the seal ring 300 to the position of the ring groove 220 of the deep hole 210, and the pull rod 30 is pushed in reverse, so that the seal ring 300 exits the outer sleeve 10 and enters the ring groove 220 of the deep hole 210 under its own restoring force. Next, as shown in fig. 9, the seal ring assembling apparatus 100 of the present embodiment is withdrawn from the deep hole 210, and the installation of the seal ring 300 in the deep hole 210 is completed. A plurality of seal rings 300 may be installed in the deep hole 210 in sequence according to the above steps. The sealing ring assembling device 100 of the present embodiment is more convenient, time-saving and labor-saving to install the sealing ring 300 in the deep hole 210. In addition, the seal ring 300 is not easily damaged during installation.

The deep hole 210 is generally vertically extended, and therefore, it is necessary to adjust the angle of the seal ring assembling apparatus 100 to a vertical state and then insert the same into the deep hole 210.

In this embodiment, the pull rod 30 further includes a rod 31, one end of the rod 31 is an operating portion 311, the other end of the rod 31 is detachably connected to one end of the main body 32, and the other end of the main body 32 has a receiving groove 322.

In this embodiment, the rod 31 and the body 32 are connected in a plug-in manner. Specifically, one end of the rod body 31 opposite to the operation portion 311 is provided with a jack, the main body 32 is provided with a plug portion 321, the plug portion 321 is inserted into the jack, and the plug portion 321 can be in interference fit with the jack, so that the rod body 31 and the main body 32 always move synchronously. The rod body 31 and the main body 32 of the embodiment have larger structural difference, and the assembly mode is adopted, so that the rod body 31 and the main body 32 can be respectively processed, the processing difficulty is reduced, and the assembly difficulty of the seal ring assembly device 100 can also be reduced.

In this embodiment, the seal ring assembling apparatus 100 further includes a guiding cylinder 20, and the guiding cylinder 20 is sleeved on the outer sleeve 10 and on the pull rod 30. The guide cylinder 20 is tightly matched with the pull rod 30 and used for guiding the left and right movement of the pull rod 30 so as to improve the movement precision of the pull rod 30. During the process of installing the seal ring 300, the guide cylinder 20 and the outer sleeve 10 are fixed together, and the pull rod 30 is moved relative to the guide cylinder 20 and the outer sleeve 10.

In this embodiment, the sealing ring assembling device 100 further includes a limiting body 40, and the right end portion of the guide cylinder 20 is configured with a yielding space 21. The right section of the complete cylinder may be cut approximately in half to form the relief space 21. The spacing body 40 is located in the abdicating space 21 and is configured to axially spacing the main body 32 to limit the depth of the receiving groove 322 into the outer sleeve 10. The axial direction of the present embodiment is also the left-right direction. Limiting the depth of receiving groove 322 into outer sleeve 10, i.e., limiting the depth of seal ring 300 into outer sleeve 10, as shown in FIG. 5, advantageously reduces the amount of deformation of seal ring 300 to reduce damage to seal ring 300.

In this embodiment, the limiting body 40 is a non-integral ring structure and is sleeved on the pull rod 30, and the limiting body 40 is axially limited by the end surface of the guide cylinder 20 surrounding the abdicating space 21. For example, the limiting body 40 may be a half ring, smaller than a half ring, or larger than a half ring. The annular structure of the stopper body 40 is limited by the size of the escape space 21 of the guide cylinder 20.

In this embodiment, the position-limiting body 40 and the accommodating groove 322 are located on the same side of the pull rod 30. The right end of the pull rod 30 is provided with two protrusions arranged at intervals, and a containing groove 322 is formed between the two protrusions. The protrusion forming the receiving groove 322 is restricted by the restricting body 40 during the leftward movement, and cannot move further leftward.

As shown in fig. 3-6, in the present embodiment, the right end portion of the guiding cylinder 20 extends out of the outer sleeve 10, and two opposite end surfaces of the guiding cylinder 20, which participate in enclosing the abdicating space 21, axially limit the main body 32 respectively. The left end face of the surrounding abdicating space 21 is used for left limiting of the limiting body 40, namely left limiting of the main body 32 is carried out through the limiting body 40. The right end of the enclosed abdicating space 21 limits the body 32 to the right.

In this embodiment, the right end of the guiding cylinder 20 is configured with an inserting space 22 communicated with the abdicating space 21, and the right end of the main body 32 is inserted into and matched with the inserting space 22 and is limited in the inserting space 22. The main part 32 is a movable part, and the right end of the main part is limited, so that the installation performance is improved, and the main part 32 is prevented from colliding with foreign objects or workers.

In this embodiment, the sealing ring assembling apparatus 100 further includes an end cap 50, and the end cap 50 is sleeved on an end of the guide cylinder 20 facing away from the operating portion 311 and has an accommodating space 51 (as shown in fig. 2) for the main body 32 to enter. During the process of installing the sealing ring 300, the relative position of the end cap 50 and the guide cylinder 20 is fixed. When the main body 32 moves to the rightmost end, that is, when being limited in the insertion space 22, the end cap 50 covers the periphery of the right end of the main body 32, so as to further improve the safety. The end cap 50 can be matched with the right end of the guide cylinder 20 in a clamping manner, and the connection is convenient and quick.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
