Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring assembly, in particular to an assembly tool for an annular sealing ring. Background Art

[0002] The connecting sleeve is a key component for realizing the connection function in the self-drilling anchoring system. That is, in a construction environment with limited space, the anchor rod needs to be connected and extended by using the connecting sleeve to complete the entire construction process. Due to the large length and small aperture of the connecting sleeve, when manually installed by workers, a large amount of time is required for installation and adjustment, which is not only difficult but also inefficient.

[0003] Chinese Patent (Publication No.: CN106564031A) discloses an installation tool for a connecting sleeve sealing ring; specifically, it discloses an annular cylindrical sleeve and an annular cylindrical push rod. One end of the sleeve is welded with a limiting ring, and one end of the push rod has an annular end face. The diameter of the annular end face is larger than the outer diameter of the push rod and smaller than the inner diameter of the sleeve; the push rod passes through the inside of the sleeve, and its annular end face is at the other end of the sleeve, that is, on the side different from the limiting ring. When in use, the sealing ring is placed at the annular end face, and then the tool is placed into the connecting sleeve. The limiting ring is stuck at one end of the connecting sleeve, and the push rod is gently pushed. The annular end face pushes the sealing ring into the sealing groove to complete the installation operation of the sealing ring. This tool can conveniently and quickly push the flat sealing ring into the sealing groove to complete the installation of the sealing ring.

[0004] During the use of the anchor rod, it is found that using an annular rubber sealing ring (sealing ring) with a groove opened on the outer ring surface (matching with the annular boss in the middle of the inner cavity of the connecting sleeve) can better prevent the leakage of cement slurry. However, during the assembly using the above tool, it is found that when the push rod pushes this kind of sealing ring, the groove on the outer ring surface of the sealing ring cannot well cooperate with the annular boss in the middle of the inner cavity of the connecting sleeve; for example, only one side of the sealing ring side fits against the corresponding annular boss. After increasing the length of the sleeve, it is found that the assembly result of the sealing ring is uncertain, that is, randomly some or all of the sealing ring crosses over the annular boss, and there is also a perfect assembly situation.

[0005] Therefore, we have designed an assembly tool for an annular sealing ring. Summary of the Utility Model

[0006] In order to overcome the deficiencies in the background art, the utility model discloses an assembly tool for an annular sealing ring.

[0007] To achieve the above invention purpose, the utility model adopts the following technical solutions:

[0008] The assembly tool for an annular sealing ring includes:

[0009] A base, the diameter of which is smaller than the diameter of the connecting sleeve, and the lower end of the base has an expanded diameter support portion for fitting and supporting the bottom surface of the connecting sleeve through the expanded diameter support portion;

[0010] A sleeve, with a diameter smaller than that of the connecting sleeve. An expanding neck portion is provided in the inner cavity of the lower end of the sleeve, and a limiting ring is provided on the barrel of the upper end to facilitate pressing against the top surface of the connecting sleeve.

[0011] A push rod, with the upper end passing through the sleeve. A push plate matching the expanding neck portion is provided at the lower end of the push rod.

[0012] Wherein, the depth of the expanding neck portion is greater than the thickness of the push plate, so that the corresponding two end portions of the annular sealing ring after being twisted and deformed can be clamped into the expanding neck portion.

[0013] Preferably, the push plate has magnetic attraction to facilitate magnetic adsorption on the step surface of the expanding neck portion.

[0014] Preferably, the push plate is coaxially rotatably connected to the end of the push rod, and the rod body of the push rod is in threaded cooperation with the inner wall of the sleeve.

[0015] Preferably, a rotating handle is provided at the position of the rod body of the push rod above the sleeve.

[0016] Preferably, a threaded portion is provided on the rod body of the upper end of the push rod, and a threaded hole matching the threaded portion is provided in the middle of the bottom surface of the base.

[0017] Preferably, the distance between the top surface of the base and the bottom surface of the annular boss of the connecting sleeve is adapted to the thickness of one side surface of the groove of the annular sealing ring.

[0018] Preferably, the push rod is of a hollow structure.

[0019] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0020] 1. Due to the setting of the base, it can limit the part of the annular sealing ring that crosses the annular boss of the connecting sleeve during the process of the push rod pushing the annular sealing ring downward. Therefore, it can effectively solve the technical problem that the annular sealing ring partially or completely crosses the annular boss in the prior art, and improve the qualified rate of the assembly of the annular sealing ring.

[0021] 2. The push plate has magnetic attraction, the push rod has a limiting structure or the push rod is in threaded cooperation with the sleeve, which can prevent the push rod from disengaging from the sleeve during use.

[0022] 3. The setting that the upper end portion of the push rod has a threaded portion and the bottom surface of the base has a threaded hole can, when not in use, make the base, the sleeve and the push rod connected together by threading the upper end of the push rod through the sleeve and then threading it onto the base, preventing the situation of being scattered and difficult to find during the next use.

[0031] Embodiment 1, in combination with the attached Figure 1-4 , an assembly tool for the annular sealing ring 5, including a base 1, a sleeve 2 and a push rod 3; the diameter of the base 1 is smaller than the diameter of the connecting sleeve 4, and the lower end has a diameter-expanded support part 11; during use, the connecting sleeve 4 is sleeved on the base 1 and pressed on the top surface of the diameter-expanded support part 11; according to needs, the base 1 and the connecting sleeve 4 are in a small clearance fit, that is, after the connecting sleeve 4 is sleeved on the base 1, the connecting sleeve 4 is almost in a coaxial posture with the base 1.

[0032] The diameter of the sleeve 2 is smaller than that of the connecting sleeve 4. An expanded neck portion 21 is provided in the inner cavity of the lower end of the sleeve 2, and a limiting ring 22 is provided on the barrel body of the upper end. When in use, the lower end of the sleeve 2 is inserted into the inner cavity of the connecting sleeve 4, and the limiting ring 22 presses against the top surface of the connecting sleeve 4. As needed, there is a small clearance fit between the base 1 and the connecting sleeve 4, that is, after the connecting sleeve 4 is sleeved on the base 1, the connecting sleeve 4 is almost in a coaxial posture with the base 1. As needed, the outer diameter of the sleeve 2 and the diameter of the base 1 can be designed to be the same size.

[0033] A push plate 31 matching the expanded neck portion 21 is provided at the lower end of the push rod 3. When in use, the upper end of the push rod 3 penetrates through the sleeve 2, and the push plate 31 is located in the inner cavity of the expanded neck portion 21.

[0034] Further, the depth of the expanded neck portion 21 is greater than the thickness of the push plate 31, so that the corresponding two end portions of the annular sealing ring 5 after being twisted and deformed are caught in the expanded neck portion 21.

[0035] When in use, the base 1 is placed vertically, and then the connecting sleeve 4 is sleeved on the base 1. The upper end of the push rod 3 penetrates through the sleeve 2, and the push plate 31 is located in the inner cavity of the expanded neck portion 21 and fits against the stepped surface of the expanded neck portion 21. After the annular sealing ring 5 is twisted 90 degrees and deformed, the corresponding two end portions of the annular sealing ring 5 are caught in the expanded neck portion 21. Subsequently, the lower end of the sleeve 2 is inserted into the inner cavity of the connecting sleeve 4, and the limiting ring 22 presses against the top surface of the connecting sleeve 4. Finally, the push rod 3 is slowly pushed downward until it cannot be moved downward to complete the assembly operation of the annular sealing ring 5.

[0036] Due to the setting of the base 1, it is possible to limit the part of the annular sealing ring 5 that crosses the annular boss of the connecting sleeve 4 during the process of pushing the annular sealing ring 5 downward by the push rod 3. Therefore, it can effectively solve the technical problem that part or all of the annular sealing ring 5 crosses the annular boss in the prior art, and improve the qualification rate of the assembly of the annular sealing ring 5.

[0037] Further, after the base 1 and the connecting sleeve 4 are fitted, the distance between the top surface of the base 1 and the bottom surface of the annular boss of the connecting sleeve 4 is adapted to the thickness of one side surface of the groove of the annular sealing ring 5.

[0038] As needed, to reduce the weight of the push rod 3, the push rod 3 can be designed as a hollow structure.

[0039] Embodiment 2, an annular sealing ring 5 assembly tooling. On the basis of Embodiment 1, the push plate 31 has magnetic properties, that is, the push plate 31 can be magnetically adsorbed on the stepped surface of the expanded neck portion 21 to prevent the push rod 3 from disengaging from the sleeve 2 during use.

[0040] Embodiment 3, an annular sealing ring 5 assembly tooling. On the basis of Embodiment 1, a limiting structure is provided at the position of the push rod 3 above the sleeve 2 to prevent the push rod 3 from disengaging from the sleeve 2 through the limiting structure.

[0041] Embodiment 4, an assembly tool for an annular sealing ring 5. On the basis of Embodiment 1, the push plate 31 is coaxially and rotatably connected to the end of the push rod 3, and the rod body of the push rod 3 is in threaded fit with the inner wall of the sleeve 2. In this way, not only can the threaded fit between the push rod 3 and the sleeve 2 prevent the push rod 3 from detaching from the sleeve 2, but also the function of slowly pushing the annular sealing ring 5 downward can be realized when the push rod 3 is rotated.

[0042] To facilitate the rotation of the push rod 3, a rotating handle 32 is provided at the position of the rod body of the push rod 3 above the sleeve 2.

[0043] Embodiment 5, in combination with the attached Figure 5-6 , an assembly tool for an annular sealing ring 5. On the basis of any one of Embodiments 1 to 4, a threaded portion 33 is provided on the rod body at the upper end of the push rod 3, and a threaded hole 12 matching the threaded portion 33 is provided in the middle of the bottom surface of the base 1. That is, when not in use, the push rod 3 can pass through the sleeve 2 and be in threaded fit with the base 1, so that the base 1, the sleeve 2 and the push rod 3 are connected together to prevent the situation of being scattered and difficult to find during the next use.
