[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figures 1 to 4 As shown, a filter element pulling tool comprises:

[0030] A support platform 1, which is arranged on the step of the filter element cavity, and a cross bar 11 is fixedly arranged on the top surface, and a through hole 12 is arranged in the middle of the cross bar 11;

[0031] A hand wheel 13, the hand wheel 13 is arranged on the cross bar 11, and a hand bar 13A of the hand wheel 13 passes through the through hole 12;

[0032] A positioning hook 14, which is fixedly arranged at one end of the hand lever 13A away from the cross bar 11, and has a bent portion 14A at the bottom end;

[0033] Wherein, the hand lever 13A moves in the vertical direction;

[0034] The bent portion 14A is used to pass through the connecting hole on the filter element.

[0035] First, place the support platform 1 on the step of the filter element cavity to ensure that the platform is stable and will not slide. Then align the bent portion 14A of the positioning hook 14 with the connection hole on the filter element so that it can be inserted smoothly. Rotate the handwheel 13, and the hand lever 13A of the handwheel 13 will drive the positioning hook 14 to move in the vertical direction, so that the positioning hook 14 is firmly connected to the filter element. When the filter element needs to be removed, just rotate the handwheel 13 in the opposite direction, and the positioning hook 14 will rise in the vertical direction, thereby pulling the filter element out of the cavity. During the whole process, the design of the crossbar 11 and the through hole 12 enables the handwheel 13 to rotate stably, and the support platform 1 provides a stable support.

[0036] By using the filter element pulling tool, the replacement of the filter element becomes simpler and faster, and the work efficiency is improved; the firm connection between the positioning hook 14 and the filter element ensures the stability and safety during the disassembly process and reduces the occurrence of accidents; the stability of the support platform 1 ensures that the tool will not shake or slip during work, further improving the accuracy and reliability of the operation; the rotation operation of the handwheel 13 makes the disassembly process more labor-saving and reduces the labor intensity of the operator.

[0037] As a preference of the above embodiment, the supporting platform 1 is configured to be hollowed out on all sides.

[0038] The hollow design makes the support platform 1 more transparent, and the operator can more clearly observe the connection status between the filter element and the tooling when in use. The enhanced visibility helps to ensure accuracy during operation and prevent misoperation caused by visual blind spots. The hollow design significantly reduces the overall weight of the tooling. Compared with the traditional solid design, the hollow platform is lighter, allowing operators to carry and operate the entire tooling more easily. During long-term or high-intensity work, it can significantly reduce the burden on operators and improve work comfort and efficiency.

[0039] In this embodiment, two positioning hooks 14 are provided, a connecting plate 15 is fixedly provided at the lower end of the hand lever 13A, and the two positioning hooks 14 are symmetrically fixedly provided on the connecting plate 15 .

[0040] When the operator rotates the hand wheel 13, the hand rod 13A drives the connecting plate 15 and the two positioning hooks 14 thereon to move in the vertical direction. Since the two positioning hooks 14 are symmetrical, they can evenly apply force to the filter element, ensuring that the filter element is evenly stressed during disassembly or installation. As the hand wheel 13 rotates, the positioning hooks 14 gradually penetrate into the connecting holes of the filter element and are firmly connected to the filter element. Once the connection is firm, the operator can disassemble or install the filter element.

[0041] The uniform force applied by the two positioning hooks 14 ensures that the filter element is evenly stressed during removal or installation, effectively preventing damage or displacement caused by uneven force. This design also makes operation easier and safer, improves work efficiency, and the symmetrically designed positioning hooks 14 also enhance the aesthetics and practicality of the tooling, making the tooling more in line with the operator's usage habits and needs.

[0042] In this embodiment, a circle of support blocks 16 is fixedly disposed above the through holes 12 .

[0043] A circle of support blocks 16 fixedly arranged above the through hole 12 not only provides a firm support for the hand wheel 13, ensuring its stability during operation, but also enhances the durability and reliability of the entire tooling. The presence of the support blocks 16 makes it difficult for the hand wheel 13 to shake or shift when rotating, thereby ensuring the accurate movement of the positioning hook 14 and improving work efficiency. The design of the support blocks 16 also makes the structure of the tooling more reasonable and sturdy, thereby extending the service life of the tooling.

[0044] In this embodiment, the bending portion 14A is configured to be arc-shaped to accommodate filter element connecting holes of different shapes.

[0045] The bending portion 14A of the positioning hook 14 is designed to be arc-shaped, which significantly improves the applicability and flexibility of the filter element pulling tooling, so that the tooling can easily adapt to filter element connecting holes of different shapes and sizes, without the need to replace positioning hooks 14 of different shapes or make additional adjustments. This not only simplifies the operation process and improves work efficiency, but also reduces the difficulty and cost of operation. In addition, the arc-shaped bending portion 14A can fit tightly into the filter element connecting hole, ensuring a firm connection between the positioning hook 14 and the filter element, thereby improving the stability and reliability of the operation.

[0046] In this embodiment, the handle 13B of the hand wheel 13 is made of anti-slip material and is provided with a concave-convex texture.

[0047] The handle 13B of the handwheel 13 is made of anti-slip material and has a concave-convex texture design, which improves the operating stability and comfort of the operator. The anti-slip material and the concave-convex texture work together to effectively prevent the occurrence of hand slippage and reduce the safety risks caused by operational errors. The good grip also makes the operation easier and more comfortable, thereby improving work efficiency.

[0048] In this embodiment, the connection between the positioning hook 14 and the handle 13A is fixed by a plurality of nuts 2 .

[0049] The use of nut 2 to fix the connection between the positioning hook 14 and the hand rod 13A not only ensures the stability and reliability of the connection, but also makes the disassembly and replacement of the positioning hook 14 more convenient. Since the structure of the nut 2 fixing method is simple and clear, the operator can quickly and accurately complete the tightening and loosening of the nut 2, thereby easily realizing the disassembly and replacement of the positioning hook 14, which not only improves work efficiency but also reduces the difficulty of operation, making the tooling more convenient in maintenance and maintenance. In addition, the firmness of the nut 2 fixation also ensures that the positioning hook 14 is not easy to loosen or fall off during work, further enhancing the safety and reliability of the tooling.

[0050] As a preferred embodiment of the above embodiment, a magnetic adsorption pad 3 is fixedly provided under the supporting platform 1 for adsorbing on the step of the filter element cavity.

[0051] When the filter element needs to be disassembled or installed, the operator first places the support platform 1 with the magnetic adsorption pad 3 close to the step of the filter element cavity. The magnetic adsorption pad 3 uses its own magnetic properties to interact with the step of the filter element cavity when it is close to the step of the filter element cavity, so that the magnetic adsorption pad 3 can fit tightly on the step.

[0052] The introduction of the magnetic adsorption pad 3 enables the supporting platform 1 to be firmly adsorbed on the step of the filter element cavity, thereby improving the stability and safety of the tooling. It not only simplifies the fixing process between the tooling and the filter element cavity, but also reduces the difficulty and complexity of operation. The close fitting characteristics of the magnetic adsorption pad 3 also reduce the shaking or displacement of the tooling that may occur during operation, further ensuring the accuracy and reliability of the operation.
