[0023] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0024] First embodiment

[0025] This embodiment provides a plunger assembly device 4 for a propeller. Please refer to Figure 2 and Figure 3, including a support member 40 and an adjusting assembly 42. An elastic body 41 is fixedly provided at one end of the support member 40. The support member 40 is used to extend into the lubricating oil pipe 3 and the elastic body 41 is used to extend into the plunger 1; the adjusting assembly 42 is arranged on the support member 40 and connected to the elastic body 41. The adjusting assembly 42 is used to drive the elastic body 41 to undergo elastic deformation so as to be supported on the inner wall of the plunger 1, and the elastic body 41 can be separated from the inner wall of the plunger 1 under the action of the restoring force.

[0026] Under the adjustment of the adjustment component 42, the elastomer 41 is elastically deformed to support the inner wall of the plunger 1, and then the plunger 1 is driven by the support member 40 to extend into the lubricating oil pipe 3 for assembly. After the assembly is completed, the elastomer 41 is separated from the inner wall of the plunger 1 under the action of the restoring force, so that the support member 40 extends out of the lubricating oil pipe 3; this facilitates the assembly of the plunger 1, and there is no need to perform a simple and rough installation method on the plunger 1, thereby reducing the damage to the plunger caused by collisions.

[0027] Furthermore, the elastic body 41 can be made of nylon material, and directly contact the plunger 1 during use to avoid damaging the plunger 1; the support member 40 and the adjustment component 42 can be made of metal material to ensure the strength requirements for use.

[0028] In the optional scheme of this embodiment, it is more preferred that the adjusting component 42 is used to circumferentially squeeze the elastomer 41 so that the elastomer 41 undergoes elastic deformation to expand circumferentially so as to be supported on the inner wall of the plunger 1. By circumferentially squeezing the elastomer 41 to cause the circumferential expansion deformation, the plunger 1 can be circumferentially supported, thereby improving the support stability; and the adjusting component 42 can release the circumferential squeezing of the elastomer 41, and the elastomer 41 can be separated from the inner wall of the plunger 1 under the action of the restoring force, thereby facilitating separation from the inner wall of the plunger 1 and avoiding affecting the position of the plunger 1 during the withdrawal of the support member 40 and the adjusting component 42.

[0029] In the optional scheme of this embodiment, it is more preferred that the adjustment component 42 includes a driving member 421 and a transmission member 422, the elastomer 41 is coaxially sleeved on the outside of the transmission member 422 along the circumferential direction, the outer peripheral wall of the transmission member 422 has a first conical surface 423, and the inner peripheral wall of the elastomer 41 has a second conical surface 411 that can fit with the first conical surface 423; the driving member 421 is arranged on the support member 40 and connected to the transmission member 422; the driving member 421 is used to drive the transmission member 422 to move axially relative to the elastomer 41, and the circumferential extrusion of the elastomer 41 is achieved through the cooperation of the first conical surface 423 and the second conical surface 411, so that the elastomer 41 expands circumferentially for circumferential support on the inner wall of the plunger 1, or the extrusion of the elastomer 41 is released so that the elastomer 41 is separated from the inner wall of the plunger 1 under the restoring force.

[0030] In the optional scheme of this embodiment, it is more preferred that the driving member 421 includes a knob 424 and a connecting rod 425, and the support member 40 is arranged as a support tube; the connecting rod 425 coaxially penetrates the support member 40, and one end of the connecting rod 425 is coaxially connected to the transmission member 422, the other end of the connecting rod 425 extends out of the support member 40 and the outer wall is fixedly sleeved with a knob 424; the connecting rod 425 is driven by the knob 424 to move linearly relative to the support member 40 in the axial direction, and the transmission member 422 is driven to move linearly relative to the elastomer 41, thereby circumferentially squeezing or releasing the squeezing of the elastomer 41; the connecting rod 425 and the support member 40 are coaxially arranged to facilitate the overall extension into or extension of the lubricating oil pipe 3.

[0031] Furthermore, the diameter of the support pipe should be smaller than that of the lubricating oil pipe 3 to ensure that the lubricating oil pipe can enter and exit.

[0032] In the optional scheme of this embodiment, it is more preferred that one end of the connecting rod 425 is threadedly connected to the elastomer 41, wherein the elastomer 41 is fixedly connected to one end of the support member 40 by bonding; the end of the support member 40 away from the elastomer 41 is coaxially and fixedly provided with a washer 43, and the washer 43 is coaxially sleeved outside the connecting rod 425, and the coaxiality of the connecting rod 425 is controlled by the washer 43 to avoid shaking during the movement of the connecting rod 425, wherein the connecting rod 425 can be rotatably connected to the washer 43; the knob 424 is rotated by external force to drive the connecting rod 425 and the transmission member 422 to rotate relative to the elastomer 41. Since the connecting rod 425 is threadedly connected to the elastomer 41, the rotation of the connecting rod 425 will cause the transmission member 422 to move linearly along the axial direction relative to the elastomer 41, thereby circumferentially squeezing or releasing the squeezing of the elastomer 41.

[0033] In addition, one end of the connecting rod 425 can also be threadedly connected to the supporting member 40. During the process of threaded rotation of the connecting rod 425 relative to the supporting member 40, as long as the supporting member 40 is kept stationary, the transmission member 422 can be driven to move linearly.

[0034] In addition, the connecting rod 425 can also be slidably matched with the support member 40 and the elastic body 41, and the transmission member 422 can be driven to move linearly by pulling the connecting rod 425 to slide relative to the support member 40 and the elastic body 41.

[0035] In an alternative solution of this embodiment, preferably, the inner diameter of the first conical surface 423 and the inner diameter of the second conical surface 411 both gradually increase in the direction away from the driving member 421; and the maximum inner diameter size of the first conical surface 423 is at least greater than the minimum inner diameter size of the second conical surface 411; further, the changing trend of the inner diameter size of the first conical surface 423 is the same as that of the inner diameter size of the second conical surface 411. When the transmission member 422 is flush with the elastic body 41, the first conical surface 423 and the second conical surface 411 just fit together; by driving the transmission member 422 to move inward to circumferentially squeeze the elastic body 41, and by driving the transmission member 422 to move outward to relieve the circumferential squeeze on the elastic body 41.

[0036] In an alternative solution of this embodiment, preferably, the connecting rod 425 and the transmission member 422 can be detachably connected; specifically, the detachable connection can be achieved by bolts, which is convenient for installation and disassembly.

[0037] In an alternative solution of this embodiment, preferably, the propeller plunger assembly device 4 provided in this embodiment further includes a handle 44. The handle 44 can be fixedly sleeved outside one end of the connecting rod 425 or fixedly sleeved outside the support member 40. By providing the handle 44, it is convenient for the operation of the overall assembly device, such as transfer and handling.

[0038] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
