Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to an adjustable filter wrench. Background Technology

[0002] The existing patent publication number (CN210704532U) discloses a steel belt filter wrench, belonging to the technical field of wrenches. It includes a wrench arm, one end of which is equipped with a mounting frame. A steel clamp band is mounted on the mounting frame, and a first pin and a second pin are installed inside the mounting frame. One end of the steel clamp band is rotatably connected to the first pin, and the other end of the steel clamp band is rotatably mounted with an adjusting block via a third pin. The adjustment range is limited by the engagement of the pins with the adjusting groove; however, its adjustment range is limited, the adjusting groove position is fixed and cannot be adjusted, the steel belt surface is flat and prone to slipping, and after long-term use, if the gap increases due to wear (e.g., in the adjusting groove), the actual inner circumference of the steel belt will increase, making it unable to fit with the corresponding filter cover, thus making disassembly difficult.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] This invention provides an adjustable filter wrench to solve the technical problems mentioned in the background art.

[0005] The present invention adopts the following technical solution to solve the above-mentioned technical problems: An adjustable filter wrench includes a winding adjuster and a nylon braided belt, wherein one end of the nylon braided belt is fixed to the winding adjuster and the other end is wound inside the winding adjuster; it also includes a handle that is rotatably disposed inside the winding adjuster and adjusts the winding of the nylon braided belt by the winding adjuster.

[0006] Preferably, the winding adjuster includes a winding shell with a storage cavity for winding and storing nylon braided tape. A rotating shaft is rotatably mounted inside the winding shell, and one end of the nylon braided tape is fixed to the side of the rotating shaft. When the rotating shaft rotates, the nylon braided tape is wound to the outside of the rotating shaft or unwound relative to the rotating shaft. A storage opening is provided on the side of the winding shell to connect the outside with the storage cavity. The nylon braided tape passes through the storage opening and enters the storage cavity. The winding shell is made of steel or iron.

[0007] Preferably, the end of the handle is coaxially fixed with the upper end of the shaft, and the handle can rotate relative to the winding shell about the axis of the shaft. In this way, the handle acts as a lever arm to easily drive the shaft to rotate and thus wind up the nylon braided tape. After the nylon braided tape is wound up, it clamps the filter cover.

[0008] Preferably, the direction in which the filter cover is loosened relative to the filter is consistent with the direction in which the nylon braided tape is wound up after the handle is rotated.

[0009] Preferably, the outer wall of the winding shell is provided with a slot, one end of the nylon braided tape is inserted into the slot, and a fixing rivet passes through the winding shell and clamps the nylon braided tape in the slot.

[0010] Preferably, a handle is fixedly fitted to the tail end of the handle, and the handle is made of plastic or rubber.

[0011] Preferably, a rubber anti-slip sheet is glued and fixed to the side wall of the winding shell located between the two ends of the nylon braided strip, and the thickness of the rubber anti-slip sheet does not exceed the thickness of the nylon braided strip.

[0012] The advantages and positive effects of this utility model are: First, place the nylon braided tape outside the filter cover. With one hand, fix the winding adjuster on the side opposite the filter cover. Then, turn the handle to rotate the shaft and wind up the nylon braided tape. As the nylon braided tape winds up, it gradually tightens and clamps the filter cover on the outside. When the nylon braided tape is fully clamped relative to the filter cover, the torque force of the handle is transmitted to the filter cover through the nylon braided tape, causing the filter cover to loosen relative to the filter and thus be removed. The adjustment process is convenient and practical. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance. The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: like Figure 1-5 As shown, the adjustable filter wrench of this utility model includes a winding adjuster 11 and a nylon braided belt 10, wherein one end of the nylon braided belt 10 is fixed on the winding adjuster 11 and the other end is wound inside the winding adjuster 11; it also includes a rotating handle 12, which is rotatably disposed inside the winding adjuster 11 and adjusts the winding amount of the nylon braided belt 10 by the winding adjuster 11 to change the extension length of the nylon braided belt 10, thereby fitting filter covers 20 with different outer diameters.

[0018] Preferably, the winding adjuster 11 includes a winding shell 14, which has a storage cavity 19 for winding and storing the nylon braided tape 10. A rotating shaft 18 is rotatably provided inside the winding shell 14. One end of the nylon braided tape 10 is fixed to the side of the rotating shaft 18. When the rotating shaft 18 rotates, the nylon braided tape 10 is wound to the outside of the rotating shaft 18 or unwound relative to the rotating shaft 18. A storage opening 15 is provided on the side of the winding shell 14 to communicate with the outside and the storage cavity 19. The nylon braided tape 10 enters the storage cavity 19 after passing through the storage opening 15. The winding shell 14 is made of steel or iron and has sufficient strength.

[0019] Preferably, the end of the handle 12 is coaxially fixed with the upper end of the shaft 18, and the handle 12 can rotate relative to the winding shell 14 about the axis of the shaft 18. In this way, the handle 12, acting as a lever arm, can easily drive the shaft 18 to rotate and thus wind up the nylon braided tape 10. After the nylon braided tape 10 is wound up, it clamps the filter cover 20. Once the nylon braided tape 10 has clamped and tightened the filter cover 20, the nylon braided tape 10 and the filter cover 20 cannot move relative to each other. Continue to apply force to the handle 12 (the direction of the force is as follows...). Figure 5 (F2 in the middle), the torque force will cause the filter cover 20 to loosen relative to the filter 21. The rotating shaft 18 and the rotating handle 12 are made of steel or iron and have sufficient strength.

[0020] Preferably, the direction of loosening the filter cover 20 relative to the filter 21 (the direction of the force is as follows) Figure 5 The direction of force (F1) is consistent with the direction in which the nylon braided tape 10 is wound up after the handle 12 is rotated (the direction of force is as follows). Figure 5 (F2 in the middle).

[0021] Preferably, the outer wall of the take-up shell 14 is provided with a slot 16, one end of the nylon braided tape 10 is inserted into the slot 16, and a fixing rivet 17 passes through the take-up shell 14 and clamps the nylon braided tape 10 in the slot 16 (e.g., Figure 2 ).

[0022] Preferably, a handle 13 is fixedly fitted to the tail end of the handle 12. The handle 13 is made of plastic or rubber. The handle 13 increases the diameter of the grip position to improve the comfort of hand grip, and the use of rubber can improve the anti-slip property.

[0023] Preferably, a rubber anti-slip sheet is adhesively fixed to the side wall of the winding shell 14 located between the two ends of the nylon braided tape 10, and the thickness of the rubber anti-slip sheet does not exceed the thickness of the nylon braided tape 10 (specific placement is as follows). Figure 1 (marked as K in the diagram), during the clamping process, after the nylon braided tape 10 is tightened, the K surface on the winding shell 14 will contact the outer wall of the filter cover 20. The clamping stability can be improved by setting a rubber anti-slip sheet.

[0024] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
