Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filter disassembly technology, and relates to a disassembly device, particularly a filter disassembly device for ships. Background Technology
[0002] Currently, ordinary oil filters are used to filter liquid media such as lubricating oil, lubricating oil, and emulsions. However, after working for a period of time, the filter element of the existing oil filter becomes clogged by contaminant particles in the oil, requiring the oil filter to be stopped and the filter element removed for cleaning.
[0003] A search revealed a Chinese patent document disclosing an oil filter cup disassembly device [Application No.: 202320203775.3; Publication No.: CN 219311198 U]. This oil filter cup disassembly device includes: a column, on which two parallel and opposite disassembly columns are mounted, with the line connecting the two disassembly columns parallel to the central axis of the column, and the axial distance between the two disassembly columns is adjustable; and a torque display meter mounted on the column. This invention allows for the disassembly of oil cups from filters of different sizes by simply moving the movable disassembly column to adjust the distance between the fixed and movable disassembly columns, ensuring that both the fixed and movable disassembly columns can be inserted into the oil inlet of the filter. This achieves a single tool suitable for disassembling oil cups from different filters. The torque display meter mounted on the column ensures consistent tightening torque for the oil cups.
[0004] Although this patent ensures that the fixed and movable disassembly columns can be inserted into the oil inlet of the filter, making it possible to use one tool to disassemble the oil cup of different filters, the device concentrates the force on the contact point between the disassembly column and the filter by inserting and connecting the disassembly column. This makes it easy to damage the contact point of the filter during the twisting process, affecting the filtration effect of the filter. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a filter disassembly device for ships. The technical problem to be solved by this utility model is: how to achieve a proper fit between the fitting component and the structure on top of the filter element, thereby increasing the stability of the insertion state, and protecting the structure in contact with the filter element during the twisting and disassembly process to reduce damage during disassembly.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A marine filter disassembly device includes a docking cylinder, a pair of operating rods rotatably connected to the top of the docking cylinder, a pair of insertion blocks fixed to the bottom of the docking cylinder, gears coaxially fixed at the pivots of the two operating rods, a push rod slidably disposed inside the docking cylinder, racks fixed to the outer walls on both sides of the push rod, and the racks on both sides of the push rod meshing with corresponding gears, and a engagement component provided at the bottom end of the push rod.
[0008] The working principle of this utility model is as follows: Two plug-in blocks can be inserted into the groove at the top of the filter element. Then, the operator drives two gears to rotate through two operating rods. After the two gears rotate, they will mesh with the rack and drive the push rod to press down. After the push rod presses down, it will drive the fitting component to press down. The fitting component thus fits with the structure at the top of the filter element, increasing the friction. Then, the two operating rods drive the docking cylinder to rotate as a whole, so that the filter element can be unscrewed and disassembled.
[0009] The fitting assembly includes a push seat fixed at the bottom of the push rod and a rubber disc fixed on the push seat. The bottom surface of the rubber disc has a flared groove, and the bottom end of the docking cylinder has a docking groove. The push seat and the docking groove are slidably engaged.
[0010] With the above structure, the rubber disc can be pushed by the pusher seat to make contact with the top structure of the filter element. During the contact process, the rubber disc is compressed, and the funnel-shaped groove fits better with the top structure of the filter element and forms a wrap, thereby filling the gap between the two plug blocks and the top groove of the filter element, increasing the stability of the plug connection, improving the twisting effect, and the rubber disc also protects the wrapped filter element structure to prevent damage to the filter element structure during twisting.
[0011] The docking cylinder is provided with a guide groove, and a guide slider is slidably connected in the guide groove. The guide slider is fixedly connected to the push rod.
[0012] With the above structure, the sliding capability of the push rod can be achieved through the sliding cooperation of the guide groove and the guide slider, and the correct sliding direction can be ensured to achieve a stable engagement state.
[0013] Both of the aforementioned control levers have anti-slip textures.
[0014] By adopting the above structure, the anti-slip texture can be used to increase the anti-slip performance when the hand is held, thereby improving safety.
[0015] A limit block is fixed at the top of the push rod.
[0016] By using the above structure, the downward pressure of the push rod can be limited by the limiting block, preventing the push rod from slipping.
[0017] The two plug-in blocks have an arc-shaped block structure.
[0018] By adopting the above structure and designing the insertion block in an arc shape, the contact surface between the insertion block and the groove on the top of the filter element is increased, reducing localized wear and friction, thereby reducing mechanical wear and damage.
[0019] Compared with existing technologies, this marine filter disassembly device has the following advantages:
[0020] 1. Two operating levers drive two gears to rotate. After the gears rotate, they mesh with the rack, causing the push rod to press down. The push rod then presses down the engagement component, which engages with the structure on top of the filter element, increasing friction. Then, the two operating levers drive the docking cylinder to rotate, allowing the filter element to be unscrewed and disassembled. During the unscrewing and disassembly process, the structure in contact with the filter element is protected to reduce damage during disassembly.
[0021] 2. Two plug-in blocks are inserted into the groove at the top of the filter element to pre-fix it, improving the overall disassembly efficiency. Attached Figure Description

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0027] like Figures 1-3 As shown, a marine filter disassembly device includes a docking cylinder 1, a pair of operating rods 2 rotatably connected to the top of the docking cylinder 1, a pair of insertion blocks 3 fixed to the bottom of the docking cylinder 1, and gears 4 coaxially fixed at the pivots of the two operating rods 2. A push rod 5 is slidably arranged inside the docking cylinder 1, and racks 6 are fixed to the outer walls on both sides of the push rod 5. The racks 6 on both sides of the push rod 5 mesh with the corresponding gears 4. A meshing component is provided at the bottom end of the push rod 5.
[0028] Two insert blocks 3 can be inserted into the groove at the top of the filter element. Then, the operator drives two gears 4 to rotate using two operating rods 2. After the gears 4 rotate, they mesh with the rack 6, which drives the push rod 5 to press down. After the push rod 5 presses down, it drives the mating component to press down, thereby filling the gap between the two insert blocks 3 and the groove at the top of the filter element, increasing the stability of the insertion state, improving the twisting effect, and protecting the filter element structure to prevent damage to the filter element structure during twisting. Then, the two operating rods 2 drive the docking cylinder 1 to rotate as a whole, and the filter element is unscrewed and disassembled.
[0029] The fitting assembly includes a push seat 7 fixed at the bottom of the push rod 5, a rubber disc 8 fixed on the push seat 7, and a docking groove 9 opened at the bottom of the docking cylinder 1, with the push seat 7 and the docking groove 9 slidingly engaged.
[0030] With the above structure, the rubber disc 8 can be pushed by the pusher 7, so that the rubber disc 8 comes into contact with the top structure of the filter element. During the contact process, the rubber disc 8 is pressed, and the flared groove fits better with the top structure of the filter element and forms a wrap, thereby filling the gap between the two plug blocks 3 and the top groove of the filter element, increasing the stability of the plug connection, improving the twisting effect, and the rubber disc 8 also protects the wrapped filter element structure to prevent damage to the filter element structure during twisting.
[0031] The docking cylinder 1 has a guide groove 10 inside, and a guide slider 11 is slidably connected inside the guide groove 10. The guide slider 11 is fixedly connected to the push rod 5.
[0032] With the above structure, the sliding capability of the push rod 5 can be achieved through the sliding cooperation between the guide groove 10 and the guide slider 11, and the correct sliding direction can be ensured to achieve a stable engagement state.
[0033] Both control levers 2 are provided with anti-slip texture 12.
[0034] By adopting the above structure, the anti-slip performance when the hand is held can be increased by the anti-slip texture 12, thereby improving safety performance.
[0035] A limit block 13 is fixed at the top of the push rod 5.
[0036] With the above structure, the downward pressure of the push rod 5 can be limited by the limiting block 13 to prevent the push rod 5 from slipping.
[0037] The two plug-in blocks 3 have an arc-shaped block structure.
[0038] By adopting the above structure, the arc-shaped design of the insertion block 3 increases the contact surface between the insertion block 3 and the groove on the top of the filter element, reducing local wear and friction, thereby reducing mechanical wear and damage.
[0039] The working principle of this utility model is as follows: Two plug-in blocks 3 are inserted into the groove at the top of the filter element. Then, the operator drives two gears 4 to rotate through two operating rods 2. After the gears 4 rotate, they mesh with the rack 6, driving the push rod 5 to press down. After the push rod 5 presses down, it drives the push seat 7 to press down. The push seat 7 pushes the rubber disc 8, so that the rubber disc 8 contacts the top structure of the filter element. The rubber disc 8 is compressed during the contact process, which better fits the top structure of the filter element, thereby filling the gap between the two plug-in blocks 3 and the groove at the top of the filter element, increasing the stability of the plug-in state, improving the twisting effect, and protecting the wrapped filter element structure to prevent damage to the filter element structure during twisting. Then, the two operating rods 2 drive the docking cylinder 1 to rotate as a whole, so that the filter element can be unscrewed and disassembled.
[0040] In summary, by inserting two plug-in blocks 3 into the groove at the top of the filter element, the operator then drives two gears 4 to rotate using two operating rods 2. After the gears 4 rotate, they mesh with the rack 6, causing the push rod 5 to press down. The push rod 5 then presses down the mating assembly, thereby filling the gap between the two plug-in blocks 3 and the groove at the top of the filter element, increasing the stability of the insertion, improving the twisting effect, and protecting the filter element structure to prevent damage during twisting. Then, the two operating rods 2 drive the docking cylinder 1 to rotate as a whole, allowing the filter element to be unscrewed and disassembled.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
