It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] The utility model provides a manual press-fitting sealing ring tool, such as Figures 1 to 4 As shown, it includes a tube sleeve body 2 with a built-in telescopic mechanism 1, the telescopic mechanism 1 includes at least one telescopic elastic body 3 with an elastic telescopic stroke, a carrier 4 arranged on the telescopic elastic body 3, the carrier 4 includes a sealing ring carrier block 5 exposed outside the tube sleeve body 2 and a limiting portion 40 limitedly set in the tube sleeve body.

[0028] Specific implementation process and principle description:

[0029] When performing the sealing ring assembly operation, the sealing ring is sleeved on the sealing ring carrier block 5. At this time, the pipe sleeve body 2 can be held with one hand to perform the current sealing ring crimping assembly operation. During the pressing process, the sealing ring carrier block 5 abuts against the opponent, and the reverse force causes the carrier 4 to retreat and compress the telescopic elastic body 3. After the carrier 4 is completely retreated, the sealing ring and the sealing ring carrier block 5 are separated and assembled in place. At this time, they are withdrawn, and the telescopic elastic body 3 elastically recovers until the carrier 4 is reset. After the reset, the limit part 40 limits the carrier.

[0030] In a specific embodiment, the tube sleeve body 2 includes a tube wall sleeve 21, one end of which is detachably equipped with a tube sleeve cover 22, and the other end is provided with an exposed window 23 for exposing the sealing ring carrier block, and the exposed window is provided with an annular rib 230 for limiting the limiting part, and the telescopic elastomer 3 is arranged between the tube sleeve cover and the carrier.

[0031] Specifically, the tube sleeve cover 22 can meet the assembly and connection requirements with the tube wall sleeve 21, which facilitates the internal assembly of the telescopic mechanism 1, and the exposed window 23 and the annular rib 230 cooperate to meet the internal limit and exposure requirements of the carrier 4. At the same time, the limit part 40 has a guiding displacement in the tube wall sleeve 21, and the telescopic stroke guide is controllable and stable.

[0032] In a specific embodiment, two telescopic elastic bodies 3 arranged in parallel are provided on the carrier 4, and the free end of any telescopic elastic body 3 abuts against the pipe sleeve cover.

[0038] In a specific embodiment, a guide sleeve 6 is provided on the inserted pile platform 221 and is arranged one-to-one with the telescopic elastic body.

[0039] Specifically, the spring can be coaxially mounted in the correct position through the guide sleeve 6 to meet the linear guidance requirements of its telescopic stroke, so that the linear stroke of the carrier 4 is more reliable and stable.

[0040] In a specific embodiment, a rectangular chamber 7 with a rectangular cross-section is provided in the sleeve body 2 , and the telescopic mechanism is arranged in the rectangular chamber 7 .

[0041] The rectangular chamber 7 facilitates the installation of the telescopic mechanism and has a circumferential limiting function, thereby effectively preventing the occurrence of circumferential loosening and displacement.

[0042] In a specific embodiment, a positioning guide protrusion 51 is provided on the end surface of the sealing ring carrier 5. A guide ring wall 52 is provided on the outer periphery of the end surface of the sealing ring carrier.

[0043] Specifically, the positioning guide protrusion 51 meets the positioning and matching requirements during assembly, so that the sealing ring assembly positioning accuracy is guaranteed, and the guide ring wall 52 can realize the sliding guiding matching of the sealing ring. Specifically, when the sealing ring carrier 5 retracts to the guide ring wall 52 and is opposite to the sealing ring, the sealing ring slides along the guide ring wall 52 and is guided to the assembly position, so that the sealing ring assembly is smooth and reliable.

[0044] From the above description, it can be found that the utility model is a manual press-fitting sealing ring tool, which meets the needs of one-handed holding for sealing ring crimping assembly, and the assembly operation is smooth and efficient.
