Description

Technical Field

[0001] This application relates to the field of assistive device technology, and more particularly to an assistive device. Background Technology

[0002] Cigarette factories use numerous large pieces of equipment in their actual production processes, such as cigarette making machines and packaging machines. After prolonged operation, the oil seals of the oil pump motors in these machines will experience wear and tear, which can easily lead to oil leakage. Therefore, it is necessary to address the oil leakage problem regularly. Due to the installation location of the oil pump motor in the equipment, disassembling the oil seal individually is very troublesome. It is also difficult for operators to reach and operate the motor using tools such as hammers and screwdrivers. Therefore, the current practice in factories to solve the oil leakage problem is usually to replace the entire oil pump motor, which is costly. Utility Model Content

[0003] The purpose of this application is to provide an auxiliary tool that can facilitate the disassembly of the oil seal of the oil pump motor in the equipment, thereby effectively solving the shortcomings of the prior art.

[0004] Therefore, this application provides an auxiliary tool, including:

[0005] The first contact element is an elongated component with a first end, which is used to cooperate with the oil seal for limiting.

[0006] The second contact element is an elongated member with a second end, which is used to engage with a preset position limit.

[0007] A connecting assembly is provided, wherein the first contact and the second contact are connected by the connecting assembly, and under the action of the connecting assembly, the first contact and the second contact move relative to each other so that the first end and the second end move away from or move closer to each other;

[0008] The preset position is a force-applying component that is movable relative to the oil seal.

[0009] In some possible implementations, the number of the first contact elements is two.

[0010] In some possible implementations, the two first contacts are located on opposite sides of the second contact.

[0011] In some possible implementations, the connection assembly includes a connecting frame, a first contact connected to the connecting frame, and a second contact threadedly engaged with the connecting frame.

[0012] In some possible implementations, the first contact includes a first segment and a second segment connected to each other, one end of the first segment being configured as a first end, the other end of the first segment being connected to one end of the second segment, and the other end of the second segment and the connecting bracket being adjustablely connected in a direction toward or away from the second contact.

[0013] In some possible implementations, the connecting frame is provided with a connecting groove of length, and the second section is connected to the connecting groove by screws.

[0014] In some possible implementations, both the first segment and the second segment are elongated components, and the length extension direction of the first segment coincides with the length extension direction of the second segment, with the second segment and the connecting frame being perpendicularly connected.

[0015] In some possible implementations, the second contact is a threaded rod, the connecting frame is provided with a threaded hole for the second contact to pass through, one end of the second contact is configured as a second end, and the other end of the second contact is provided with a screwing part for easy screwing.

[0016] In some possible implementations, the length direction of the first contact is parallel to the length direction of the second contact.

[0017] In some possible implementations, the first end of the first contact is configured in a hook shape.

[0018] The auxiliary tool provided according to the embodiments of this application includes a first contact and a second contact, both of which are elongated components. The first end of the first contact is used to engage with the oil seal for limiting, and the second end of the second contact is used to engage with a preset position for limiting. The preset position is movable relative to the oil seal. Therefore, under the action of the connecting component, the first contact and the second contact will move relative to each other, with the first end and the second end moving away from or closer to each other, thereby applying force to the oil seal and causing the oil seal to disengage from the oil pump motor. The elongated first and second contact can facilitate the disassembly of the oil seal, requiring only the replacement of the oil seal, which greatly reduces the cost. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figures 1-4 As shown in the illustration, this application provides an auxiliary tool for the disassembly process of oil seals. Cigarette factories use various large-scale equipment during production, most of which are equipped with oil pump motors. These oil pump motors contain oil seals. After prolonged operation, the oil seals wear down, leading to oil leakage. To solve this problem, factories often replace the oil pump motor. However, the location of the oil pump motor within the equipment makes oil seal disassembly difficult, requiring the entire motor to be replaced, resulting in significant costs. The auxiliary tool provided in this application aims to improve the ease of oil seal disassembly, allowing for the solution of oil leakage simply by replacing the oil seal, thereby reducing costs.

[0025] The auxiliary device includes a first contact 100, a second contact 200, and a connecting assembly. Under the action of the connecting assembly, the first contact 100 and the second contact 200 can move relative to each other. The first contact 100 is an elongated member with a first end 110 for engaging with the oil seal of the oil pump motor. The second contact 200 is also an elongated member with a second end 220 for engaging with a preset position. The preset position described is movable relative to the oil seal. The preset position is a force-applying component, and the oil seal is movable relative to the preset position. For example, the preset position can be a local position of the equipment where the oil pump motor is located. Preferably, the preset position is the shaft on which the oil pump motor oil seal is fitted. The limiting fit between the second end 220 and the preset position is that the second end 220 abuts against the shaft. The limiting fit between the first end 110 of the first contact member 100 and the oil seal is a detachable limiting fit. Preferably, the first end 110 of the first contact member 100 is hook-shaped. In this configuration, the first end 110 can achieve a hook-and-lock engagement with the oil seal, facilitating the connection and separation of the first contact 100 and the oil seal. Therefore, under the action of the connecting assembly, the first contact 100 and the second contact 200 move relative to each other, allowing the first end 110 and the second end 220 to move away from or towards each other. After the first end 110 of the first contact 100 is locked in place with the oil seal, the second end 220 of the second contact 200 rests against the shaft of the oil pump motor. Under the action of the connecting assembly... The device can apply force to the oil seal, thereby causing it to disengage from the oil pump motor. Furthermore, both the first contact 100 and the second contact 200 are elongated components, making it easier to access the oil seal in confined spaces. This facilitates the disassembly and replacement of the oil seal, thus solving the problem of oil leakage from the oil pump motor and significantly reducing costs. The auxiliary tool provided in this application enables convenient disassembly of the oil seal. When installing a new oil seal, it can be installed by tapping it with a long rod component and a hammer, requiring minimal space.

[0026] Preferably, there are two first contact members 100. The two first contact members 100 cooperate with the oil seal limit, so that two force application points are generated on the oil seal, making disassembly more convenient. In this embodiment, the two first contact members 100 are located on both sides of the second contact member 200, and the two first contact members 100 are centrally symmetrically arranged relative to the first contact member 100. In this way, two centrally symmetrical force application points are generated on the oil seal, making the force on the oil seal more symmetrical and stable, making the disassembly of the oil seal more convenient, less prone to jamming, and improving the convenience of oil seal disassembly operation.

[0027] In some embodiments, the connecting assembly includes a connecting frame 300, a first contact 100 connected to the connecting frame 300, and a second contact 200 threadedly engaged with the connecting frame 300. The threaded engagement between the second contact 200 and the connecting frame 300 enables relative movement between the second contact 200 and the connecting frame 300, thereby enabling relative movement between the first contact 100 and the second contact 200. The threaded engagement is more convenient, has a simpler structure, and lower component costs.

[0028] Preferably, the first contact 100 includes a first segment 101 and a second segment 102, which are connected to each other. One end of the first segment 101 is configured as a first end 110, and the other end of the second segment 102 is connected to one end of the second segment 102. The other end of the second segment 102 and the connecting frame 300 can be adjusted to be connected in a direction that is closer to or farther from the second contact 200. In this way, the distance between the first contact 100 and the second contact 200 can be adjusted. The first contact 100 can be adjusted according to the actual space and the size of the oil seal, which improves the adaptability of the auxiliary tool.

[0029] In this embodiment, the connecting frame 300 can be a plate-shaped structure. A connecting groove 301 is provided on the connecting frame 300. The connecting groove 301 extends through the connecting frame 300 along the thickness direction. The second section 102 is connected to the connecting groove 301 by screws. In this way, the adjustable connection between the first contact member 100 and the connecting frame 300 is realized.

[0030] Preferably, both the first segment 101 and the second segment 102 are elongated components. The length extension direction of the first segment 101 coincides with the length extension direction of the second segment 102. The second segment 102 is perpendicularly connected to the connecting frame 300. In this embodiment, the second segment 102 has a long cylindrical structure. A protruding ring 1021 is provided in the inner ring region of the end face of the second segment 102 connected to the connecting frame 300. The outer diameter of the protruding ring 1021 is slightly smaller than the inner ring size of the connecting groove 301. The outer diameter of the second segment 102 is... The inner ring size of the connecting groove 301 is larger than that of the connecting groove 301, so that the protruding ring 1021 can extend into the connecting groove 301 and the end of the second section 102 can abut against the outer surface of the connecting frame 300. The length of the protruding ring 1021 protruding from the second section 102 is less than the thickness of the connecting frame 300. Thus, by passing a screw through the connecting groove 301 and then screwing it into the second section 102 and threading it in, the adjustment connection between the second section 102 and the connecting frame 300 is more stable, which helps to improve the stability of the connection between the components.

[0031] In this embodiment, the first segment 101 is an elongated component. One end of the first segment 101 is connected to one end of the second segment 102. The length extension direction of the first segment 101 coincides with the length extension direction of the second segment 102. The other end of the first segment 101 is hook-shaped to form the first end 110 of the first contact member 100 so as to hook and cooperate with the oil seal. In this embodiment, the first contact member 100 as a whole can also be rotated and adjusted to adjust the orientation of the hook-shaped component on the first segment 101, which makes it easier to hook and cooperate with the oil seal.

[0032] Preferably, the second contact 200 is a threaded rod, and the connecting frame 300 is provided with a threaded hole 302 for the second contact 200 to pass through. One end of the second contact 200 is configured as the second end portion 220 of the second contact 200, and the other end of the second contact 200 is provided with a screwing part for easy screwing. The screwing part can be a polygonal structure to facilitate screwing operations with pliers, wrenches, etc. The threaded hole 302 is provided through the connecting frame 300 along the thickness direction, so that the length extension direction of the second contact 200 is parallel to the length extension direction of the first contact 100, and the first end portion 110 of the first contact 100 is connected to the first contact 100. The extension direction of the frame 300 is the same as the extension direction of the second end 220 of the second contact 200 relative to the extension direction of the connecting frame 300. Thus, when the oil seal is disassembled, the hook-shaped structure on the first contact 100 hooks the oil seal, and the second end 220 of the second contact 200 abuts against the shaft of the oil pump motor. Twisting the second contact 200 causes the first contact 100 to pull the oil seal outward. Thus, the parallel first contact 100 and the second contact 200 apply force more stably. More preferably, the width of the first section 101 can be smaller than the width of the second section 102, making it easier to access the oil seal in a confined space and to hook and cooperate with the oil seal.
