Description

Technical Field

[0001] The utility model relates to the technical field of O-ring installation, in particular to a deep-hole O-ring installation device. Background Art

[0002] Currently, when installing O-rings in deep, small bores on shaft-type workpieces in production workshops, such as drill stems, conversion joints, and drilling jars, assemblers install the O-rings by hand. Specifically, the O-ring is manually folded into a concave shape and placed into the hole. A long rod is then inserted into the hole to push the O-ring into the O-ring mounting groove inside the deep hole. The O-ring's elasticity is then utilized to assemble it into the O-ring groove. Traditional installation methods involve excessive assembly movements and take excessively long assembly times. Furthermore, when the inner hole for the O-ring is deep or small, it is difficult to install and can easily cause scratches between the O-ring and the inner wall, resulting in the O-ring's sealing effect failing. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a deep hole O-ring installation device, the purpose of which is to avoid bare-hand installation, prevent the O-ring sealing effect from failing and improve installation efficiency.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a deep hole O-ring installation device, including a first handle, a second handle, a first movable rod, a second movable rod and a fixed rod, the fixed rod being hinged to the first handle and the second handle respectively, the first movable rod being vertically connected to the first handle, the second movable rod being vertically connected to the second handle, the first movable rod, the second movable rod and the fixed rod being all installed downward, and the first handle and the second handle rotating in opposite directions with the fixed rod as the center of the circle.

[0005] The bottoms of the first handle and the second handle are both provided with notches, and the first moving rod and the second moving rod extend into the notches at the bottoms of the first handle and the second handle respectively and are movably connected to the first handle and the second handle respectively.

[0006] The tops of the first moving rod and the second moving rod are both provided with internal threaded through holes, and the side walls of the first handle and the second handle are provided with moving grooves, and the locking screws extend into the moving grooves and cooperate with the internal threaded through holes.

[0007] The first movable rod, the second movable rod and the fixed rod are telescopic rods.

[0008] Beneficial effects of the utility model:

[0009] 1) When installing the O-ring, place the first movable rod and the second movable rod inside the O-ring and the fixed rod outside the O-ring. By pushing the first handle and the second handle at the same time, the O-ring is subjected to external force and, under the action of the fixed rod, the O-ring is recessed inward. At this time, the O-ring can be easily placed into the O-ring groove of the deep-hole part.

[0010] 2) The first movable rod and the second movable rod move in the bottom notches of the first handle and the second handle respectively and are fixed by locking screws. The distance between the first movable rod and the second movable rod can be adjusted to achieve the installation of O-rings of different sizes.

[0011] 3) By configuring the first movable rod, the second movable rod, and the fixed rod as telescopic rods and adjusting the lengths of the first movable rod, the second movable rod, and the fixed rod, the O-ring can be installed in O-ring grooves of different depths.
