Description

Technical Field

[0001] This utility model relates to the field of disassembly tools, specifically a portable disassembly puller. Background Technology

[0002] In the field of industrial water filter maintenance, filter cartridge replacement requires the disassembly and installation of the internal sealing plate. Currently, there is a lack of specialized, standardized tools for disassembling and installing the internal sealing plate of industrial water filters.

[0003] In existing technologies, given that the inner sealing plate has a threaded connection at its center, the following disassembly and assembly method is typically used: a pull rod with an external thread at one end that matches the threaded connection is selected, and a through hole is made in the pull rod; after the pull rod is securely connected to the threaded connection of the inner sealing plate through the threaded engagement, a pry bar is inserted into the through hole of the pull rod, and the sealing plate is forcibly pried out using the lever principle. However, this disassembly and assembly method has significant technical defects: First, the operation method of using a pry bar to apply force is an imprecise force application, and the force application process is relatively rough. In actual operation, improper force application can easily damage the internal sealing ring; Second, the inner sealing plate is mostly made of aluminum alloy, which has relatively low strength and limited toughness. When using the above-mentioned pulling and dragging disassembly and assembly method, the sealing plate is very prone to deformation, breakage, and other damage due to uneven force, which seriously affects the service life and performance of the sealing plate, and also increases the maintenance cost and operational risks of industrial water filters.

[0004] Therefore, there is an urgent need for a portable disassembly puller that can accurately and smoothly disassemble and assemble the sealing plates inside industrial water filters, effectively avoiding damage to the sealing rings and sealing plates, and reducing maintenance costs and operational risks. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a solution.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A portable disassembly puller includes a connecting sleeve with an internal thread, a pressing cover plate connected to the lower end of the connecting sleeve, and a locking element on each of the left and right side plates of the pressing cover plate; it also includes a pull rod with an external thread, which is threadedly connected to the connecting sleeve, and its lower end extends out of the connecting sleeve and is rotatably connected to a pull connector for connecting the threaded connection part of a sealing plug; it also includes an adjusting rod adapted to the connecting sleeve, with a pin at the lower end of the adjusting rod and a connecting groove at the upper end of the pull rod adapted to a set screw; after the lower end of the adjusting rod is inserted into the connecting sleeve and the pin is embedded in the connecting groove, the pull rod can be moved up and down by rotating the adjusting rod, thereby realizing the disassembly and assembly of the sealing plug.

[0008] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0009] This application utilizes an adjusting rod and a pull rod to create a linear vertical force. By rotating the adjusting rod, the puller applies a linear force axially (perpendicular to the plane of the sealing plate). Compared to the "lever-oriented force" of a pry bar, this design ensures that the direction of the force is always consistent with the disassembly / installation direction of the sealing plate, avoiding tilting of the plate caused by lateral force. Compared to the violent disassembly and assembly method using a pry bar in the prior art, this design enables smooth and precise disassembly and installation of the sealing plate inside the industrial water filter, avoiding deformation, breakage, or other damage to the sealing plate due to uneven force. It also reduces the risk of damage to the internal sealing ring, greatly improving the service life of the sealing plate and the sealing ring, and reducing the maintenance cost and operational risks of the industrial water filter.

[0010] As a preferred embodiment, a further technical solution of this utility model is:

[0011] Preferably, the lower end of the connecting sleeve is provided with an external thread section, and a lock nut connector is threadedly connected to the external thread section. The crimping cover is provided with a threaded hole that matches the lock nut connector. The cooperation between the lock nut connector and the threaded hole enables quick disassembly and assembly, and facilitates the replacement of crimping cover plates of different specifications according to the size of the filter.

[0012] Preferably, the lower end of the pull rod is provided with a T-shaped connector, and the pull connector is provided with a rotating groove that is adapted to the T-shaped connector. The T-shaped connector can be connected to the rotating groove and rotate in the rotating groove.

[0013] Preferably, the ejector pin has a rectangular cross-section; the rectangular ejector pin and the connecting groove form an anti-torsion structure, preventing the adjusting rod from slipping and improving transmission efficiency; at the same time, the rectangular cross-section can withstand greater torque than the circular cross-section, making it suitable for the forceful disassembly of rusted plugs.

[0014] Preferably, the pressing cover plate is provided with a groove that fits the top side wall of the filter; the groove structure fits the side wall of the filter to achieve a self-positioning function and quickly align with the central axis.

[0015] Preferably, the locking element is a locking bolt, which is threadedly connected to the side plate of the press cover; this facilitates quick connection and disassembly of the press cover and the filter.

[0016] Preferably, the end of the locking bolt used to abut against the side wall of the filter is provided with a rubber abutment; the rubber abutment forms a buffer interface, which not only ensures the clamping force but also prevents the locking bolt from scratching the inner wall of the filter; at the same time, the rubber abutment increases the coefficient of friction, and the rubber material can still maintain effective clamping in an oily environment, preventing the tool from falling off.

[0017] Preferably, a handle is provided at the top of the lever. Attached Figure Description

[0025] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, this embodiment provides a portable disassembly puller, including a connecting sleeve 1 with an internal thread, a pressing cover plate 4 connected to the lower end of the connecting sleeve 1, and a locking element 5 on each of the left and right side plates of the pressing cover plate 4; it also includes a pull rod 6 with an external thread, which is threaded to the connecting sleeve 1, and its lower end extends out of the connecting sleeve 1 and is rotatably connected to a pull connector 7, which is used to connect to the threaded connection part of the sealing plug plate 12; it also includes an adjusting rod 8 adapted to the connecting sleeve 1, with a pin 9 at the lower end of the adjusting rod 8 and a connecting groove adapted to the pin 9 at the upper end of the pull rod 6; the lower end of the adjusting rod 8 is inserted into the connecting sleeve 1, and after the pin 9 is embedded in the connecting groove, the pull rod 6 can be moved up and down by rotating the adjusting rod 8, thereby realizing the disassembly and assembly of the sealing plug plate 12. The pull rod 6 is a screw rod with a handle 10 welded to the top; the pressing cover plate 4 includes a long top plate (length greater than the diameter of the filter 11), and a side plate on each of the left and right sides of the long top plate.

[0027] The lower end of the connecting sleeve 1 is provided with an external thread section 2, and a lock nut connector 3 is threadedly connected to the external thread section 2. The crimping cover plate 4 is provided with a threaded hole that is compatible with the lock nut connector 3. When the lock nut connector 3 is screwed down, it can be threadedly connected to the threaded hole. When it is screwed up, it is disengaged from the threaded hole, and the connecting sleeve 1 separates from the crimping cover plate 4.

[0028] The rotatable connection between the lower end of the pull rod 6 and the pull connector 7 can be either a T-joint connection or a bearing connection. When connected via a T-joint: the lower end of the pull rod 6 is provided with a T-joint, and the pull connector 7 is provided with a rotating groove that is compatible with the T-joint. The T-joint can be connected in the rotating groove and rotate in the rotating groove. When connected via a bearing, the lower end of the pull rod 6 and the pull connector 7 can be directly connected via a bearing.

[0029] When disassembling the sealing plate 12, first remove the filter cartridge pressure plate 14. Then, thread the lower end of the pull rod 6 and the pull connector 7 to the threaded connection of the sealing plate 12. The upper end of the pull rod 6 passes through the threaded hole of the pressing cover plate 4. The pressing cover plate 4 covers the top of the filter 11 and is locked by the locking piece 5. Then, rotate the locking nut 3 at the lower end of the connecting sleeve 1 and screw the locking nut 3 downward into the threaded hole of the pressing cover plate 4 to connect the connecting sleeve 1 and the pressing cover plate 4. Then, insert the adjusting rod 8 into the connecting sleeve 1. The pin 9 at the lower end of the adjusting rod 8 is embedded in the connecting groove. Hold the connecting sleeve 1 and rotate the adjusting rod 8 to drive the pull rod 6 to rotate. When the pull rod 6 rotates, the lower pull connector 7 does not rotate but only moves upward, driving the sealing plate 12 to be pulled upward. When it is pulled to the top of the filter 11, loosen the locking piece 5. Use the portable disassembly puller to pull the sealing plate 12 out and perform the filter element 13 replacement operation.

[0030] After replacing filter element 13, when installing sealing plate 12, first connect sealing plate 12 to connector 7, then place press cover 4 on top of filter 11 and lock it with locking piece 5. Insert adjusting rod 8 into connecting sleeve 1, with pin 9 at the lower end of adjusting rod 8 embedded in connecting groove. Hold connecting sleeve 1 and rotate adjusting rod 8, causing pull rod 6 to rotate. When pull rod 6 rotates, lower connector 7 does not rotate, but only moves downward, causing sealing plate 12 to move downward. After installation, install filter cartridge pressure plate 14, and then remove connecting sleeve 1, press cover 4, and pull rod 6 in sequence. Adjusting rod 8 can be provided with external threads, or not. Providing external threads results in more even force transmission.

[0031] This portable disassembly puller enables the smooth and precise disassembly and installation of the sealing plate 12 inside the industrial water filter 11, avoiding damage such as deformation and breakage of the sealing plate 12 due to uneven force. At the same time, it reduces the risk of damage to the internal sealing ring 15, greatly improving the service life of the sealing plate 12 and the ring, and reducing the maintenance cost and operational risks of the industrial water filter 11.

[0032] Furthermore, to prevent the adjusting rod 8 from slipping and improve transmission efficiency, the ejector pin 9 has a rectangular cross-section; the rectangular ejector pin 9 and the connecting groove form an anti-torsion structure; of course, those skilled in the art can also choose a cross-shaped ejector pin 9 or a flat-head ejector pin 9 similar to a screwdriver.

[0033] The crimping cover plate 4 is provided with a groove that fits the top side wall of the filter 11; the groove structure fits the side wall of the filter 11 to achieve a self-positioning function and quickly align with the central axis.

[0034] The locking element 5 is a locking bolt, which is threadedly connected to the side plate of the pressing cover 4; this facilitates quick connection and disassembly of the pressing cover 4 and the filter 11. Furthermore, to prevent scratching the filter 11, a rubber abutment is provided at the end of the locking bolt that abuts against the side wall of the filter 11; the rubber abutment also increases friction, ensuring the stability of the connection between the pressing cover 4 and the filter 11.

[0035] This portable disassembly puller, through the synergistic optimization of various technical features, systematically solves the key technical bottlenecks in existing technologies, such as nonlinear force direction, insufficient tool compatibility, dynamic instability during operation, and lack of equipment protection, thereby achieving non-destructive operation in the disassembly and assembly process of the sealing plate 12.

[0036] In addition, the device adopts a modular architecture design, with detachable connections between functional units, which significantly improves the ease of tool transportation, on-site assembly efficiency, and component maintainability, meeting the needs for rapid deployment in complex industrial environments.

[0037] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
