Description

Technical Field

[0001] This utility model relates to the field of valve maintenance and protection technology, and in particular to a tool for cleaning lead screws and a device with lead screws. Background Technology

[0002] In industrial production, valves are widely used as important components for controlling the flow of fluid media. During long-term use, valve screws will accumulate dirt and rust due to factors such as media corrosion and impurity adhesion, which accelerates the wear of the packing and shortens the service life of the valve. Currently, the cleaning of valve screws is mainly done manually, such as by wiping with copper wire brushes and sandpaper. This method is inefficient and extremely inconvenient for maintenance. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies that primarily rely on manual cleaning methods for valve screws, such as using copper wire brushes and sandpaper for wiping. This method is inefficient and extremely inconvenient for maintenance. The invention provides a tool and device for cleaning valve screws.

[0004] In a first aspect, the present invention provides a tool for cleaning a lead screw, comprising: a rod, a brush head, and a sleeve, wherein one end of the rod is connected to the brush head and the other end is connected to the inner wall of the sleeve, the axial direction of the rod is the same as the axial direction of the sleeve, the sleeve can be sleeved on the lead screw and fixed in position relative to the lead screw, and when the sleeve is sleeved on the lead screw, the brush head can contact the lead screw.

[0005] By aligning the axis of the rod with that of the sleeve, the tool boasts a compact structure. Cleaning is achieved solely through relative movement between the sleeve and the lead screw, reducing the difficulty of use. The sleeve, positioned securely around the lead screw, allows for stable placement. Operators simply rotate the lead screw, screwing it in or out of the sleeve, enabling relative movement between the lead screw and the brush head along a predetermined path, thus cleaning the lead screw and enhancing the convenience and stability of the cleaning process. Furthermore, aligning the rod's axis with that of the sleeve, compared to other configurations where the axes are perpendicular, increases the compactness of the tool's components. Connecting the rod and brush head, unlike designs where the brush head is directly attached to the sleeve's inner wall, transmits the force generated by the brush head's contact with the lead screw to the rod, causing a slight oscillation. This reduces the force on the brush head, acting as a buffer to prevent excessive localized stress and damage, thus improving the tool's durability.

[0006] The axial direction of the sleeve can be parallel to the axial direction of the lead screw, or the axial direction of the sleeve can be at a certain angle to the axial direction of the lead screw.

[0007] The rod and brush head can be connected by means of thread, snap-fit ​​or integral setting, and the rod and the inner wall of the sleeve can be connected by means of bonding, welding or threaded connection.

[0008] The brush head is made of metal wire or rigid plastic wire, etc.

[0009] The sleeve can be fixed in relative position to the lead screw by screwing or snapping it to the base of the lead screw.

[0010] This setup ensures that the tool is fixed in position relative to the lead screw when it is fitted onto the lead screw, allowing the brush head to contact the lead screw. The operator simply needs to rotate the lead screw and screw it in or out, enabling the lead screw to move relative to the brush head along a predetermined path. The brush head then rubs against the surface of the lead screw, causing dirt to be removed from the lead screw through friction. This achieves cleaning of the lead screw by the brush head, improving the efficiency and convenience of cleaning the lead screw.

[0011] The tool for cleaning lead screws further includes a U-shaped component. The end of the rod away from the brush head is connected to one end of the U-shaped component. There are two rods, one of which is connected to each end of the U-shaped component. The rods are connected to the inner wall of the sleeve through the U-shaped component.

[0012] The rod can be detachably connected to the end or screwed to the end.

[0013] The two ends of the U-shaped component are each connected to a rod and a brush head, allowing two brush heads to clean the lead screw simultaneously, thus improving the cleaning effect.

[0014] The sleeve is a cylindrical component with one end open and the other end sealed. The open side of the U-shaped component faces the open end of the sleeve, and the side of the U-shaped component away from the open side is connected to the end face of the sealed end of the sleeve.

[0015] The open side of a U-shaped component is one side extending from the two ends of the U-shaped component, and the other side of the U-shaped component is the side where the two ends of the U-shaped component meet.

[0016] When the sleeve is fitted onto the lead screw, the lead screw can extend from the open side of the U-shaped component into the concave part of the U-shaped component, so that the two ends are located on both sides of the lead screw. When the brush head is cleaning, when the lead screw generates a reaction force on the brush head, the force will be transmitted to the two ends respectively, and then distributed to the sleeve through the ends. This method of distributing the force avoids the concentration of force at a single point and improves the stability of the tool during operation.

[0017] When the sleeve is fitted onto the lead screw, the shafts of the two rods and the shaft of the lead screw are all located in the same plane.

[0018] The pressure of the two rods and the brush head on the lead screw is evenly distributed on the same plane during cleaning, avoiding excessive or insufficient pressure in some areas, making the contact between the brush head and the lead screw surface more uniform and the cleaning effect better.

[0019] The U-shaped component is an elastic component, such as a U-shaped spring or a U-shaped rubber tube, preferably a U-shaped rubber tube.

[0020] Once the lead screw extends into the concave part of the U-shaped component and comes into contact with it, the U-shaped component, being an elastic member, acts as a buffer, reducing the likelihood of tool damage when it comes into contact with the lead screw.

[0021] The U-shaped component is a flexible hollow tube component. A spring is provided inside the U-shaped component at the corresponding position of the connection between the U-shaped component and the sleeve. The spring can extend and retract along the axial direction of the sleeve.

[0022] The flexible hollow tube component is a rubber flexible tube or a plastic flexible tube, preferably a plastic flexible tube.

[0023] The flexibility of the hollow tube allows the U-shaped component to adapt to the slight bending and unevenness of the lead screw, improving the tool's adaptability. After the lead screw extends into the concave part of the U-shaped component and comes into contact with it, the presence of a spring and the flexibility of the U-shaped component reduce the probability of the lead screw directly contacting the inner wall of the top of the sleeve. This allows the U-shaped component to protect the sleeve, while the spring acts as a buffer, reducing the probability of tool damage when it comes into contact with the lead screw.

[0024] The inner wall of the open end of the sleeve is provided with a thread that can be screwed to the base of the lead screw, or the open end of the sleeve is provided with a pin hole, and the sleeve can be connected to the base of the lead screw by a pin.

[0025] The rod is a telescopic rod, which can extend and retract along its axial direction.

[0026] This setting allows the tool to clean different parts of the lead screw, improving the tool's adaptability during use.

[0027] The brush head is provided with copper bristles at its end, and the brush head contacts the lead screw through the copper bristles.

[0028] This setting improves the cleaning effectiveness of the tools.

[0029] In a second aspect, the present invention provides a device with a lead screw, employing the aforementioned tool for cleaning the lead screw, the tool being sleeved around the lead screw of the device with the lead screw.

[0030] This setting increases the service life of the lead screw in the equipment.

[0031] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a tool for cleaning lead screws. With this setting, the relative position of the tool and the lead screw is fixed when the tool is fitted onto the lead screw, and the brush head can contact the lead screw. The operator only needs to turn the handwheel at the other end of the lead screw to rotate the lead screw and screw it in or out, so that the lead screw can move relative to the brush head along a predetermined path. The brush head rubs against the surface of the lead screw, thereby causing the dirt on the lead screw to be removed from the lead screw through the friction of the brush head, thus achieving the cleaning of the lead screw by the brush head, improving the efficiency and convenience of cleaning the lead screw; 2. This utility model provides a device with a lead screw, which improves the service life of the lead screw. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0038] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0039] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0040] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0041] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0042] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0043] Example 1 like Figures 1-4 As shown, this embodiment provides a tool for cleaning a lead screw, including: a rod 1, a brush head 2, and a sleeve 3. One end of the rod 1 is connected to the brush head 2, and the other end is connected to the inner wall of the sleeve 3. The axial direction of the rod 1 is the same as the axial direction of the sleeve 3. The sleeve 3 can be sleeved on the lead screw 4 and fixed in position relative to the lead screw 4. The length of the sleeve 3 can be adapted to the length of the lead screw 4. When the sleeve 3 is sleeved on the lead screw 4, the brush head 2 can contact the lead screw 4.

[0044] By setting the axis of the rod 1 to be the same as the axis of the sleeve 3, the tool structure is made compact. During use, cleaning can be completed simply by making relative movement between the sleeve 3 and the lead screw 4, reducing the difficulty of use. By setting the sleeve 3 to be fitted over the lead screw 4 and fixed in position relative to the lead screw 4, the sleeve 3 can be stably fitted over the lead screw 4. The operator only needs to turn the handwheel at the other end of the lead screw 4 to rotate the lead screw 4 and screw it in or out, so that the lead screw 4 can move relative to the brush head 2 along a predetermined path, thereby achieving cleaning of the lead screw 4 by the brush head 2, improving the convenience and stability of the cleaning process.

[0045] The rod 1 and the brush head 2 are integrated, and the rod 1 is connected to the inner wall of the sleeve 3 by welding.

[0046] This design fixes the relative position of the tool to the lead screw 4 when it is fitted onto the lead screw 4, allowing the brush head 2 to contact the lead screw 4. The operator only needs to turn the handwheel at the other end of the lead screw 4 to rotate the lead screw 4 and screw it in or out, enabling the lead screw 4 to move relative to the brush head 2 along a predetermined path. The brush head 2 generates friction on the surface of the lead screw 4, thereby removing dirt from the lead screw 4 through friction. This achieves the cleaning of the lead screw 4 by the brush head 2, improving the efficiency and convenience of cleaning the lead screw 4.

[0047] The tool for cleaning lead screws further includes a U-shaped component 5, wherein one end of the rod 1 away from the brush head 2 is connected to one end of the U-shaped component 5, and the rod 1 is connected to the inner wall of the sleeve 3 through the U-shaped component 5; The number of rods 1 is 2, and one rod 1 is connected to each of the two ends of the U-shaped component 5.

[0048] The two ends of the U-shaped component 5 are each connected to a rod 1 and a brush head 2, which allows the two brush heads 2 to clean the lead screw 4 at the same time, thus improving the cleaning effect.

[0049] The sleeve 3 is a cylindrical component with one end open and the other end sealed. The open side of the U-shaped component 5 faces the open end of the sleeve 3, and the side of the U-shaped component 5 away from the open side is connected to the end face of the sealed end of the sleeve 3.

[0050] The open side of the U-shaped component 5 is one side of the two ends of the U-shaped component 5 extending in the same direction, and the other side of the U-shaped component 5 is the side where the two ends of the U-shaped component 5 meet at one point.

[0051] When the sleeve 3 is fitted onto the lead screw 4, the lead screw 4 can extend into the concave part of the U-shaped component 5 from the open side of the U-shaped component 5, so that the two ends are located on both sides of the lead screw 4. When the brush head 2 is cleaning, when the lead screw 4 generates a reaction force on the brush head 2, the force will be transmitted to the two ends respectively, and then distributed to the sleeve 3 through the ends. This method of distributing the force avoids the concentration of force at a single point and improves the stability of the tool when it is working.

[0052] When the sleeve 3 is fitted onto the lead screw 4, the shafts of the two rods 1 and the shaft of the lead screw 4 are all located in the same plane.

[0053] The pressure of the two rods 1 and the brush head 2 on the lead screw 4 is evenly distributed on the same plane during cleaning, avoiding excessive or insufficient pressure in some areas, making the contact between the brush head 2 and the lead screw 4 surface more uniform and the cleaning effect better.

[0054] The U-shaped component 5 is a flexible hollow tube component. A spring 6 is provided inside the U-shaped component 5 at the corresponding position of the connection between the U-shaped component 5 and the sleeve 3. The spring 6 can extend and retract along the axial direction of the sleeve 3.

[0055] The flexible hollow tube component is a plastic flexible tube.

[0056] The flexibility of the flexible hollow tube allows the U-shaped component 5 to adapt to the slight bends and unevenness of the lead screw 4, improving the tool's adaptability. After the lead screw 4 extends into the concave part of the U-shaped component and comes into contact with it, due to the presence of the spring 6 and the flexibility of the U-shaped component 5, the sleeve 3 can continue to move towards the lead screw 4, causing the U-shaped component 5 to deform. This increases the range within which the tool can clean the lead screw. When it is necessary to remove the tool from the lead screw 4, the spring 6 provides a rebound force, making it easy to remove the tool.

[0057] The inner wall of the open end of the sleeve 3 is provided with a thread that can be screwed to the base of the lead screw 4, or the open end of the sleeve 3 is provided with a pin hole, and the sleeve 3 can be connected to the base of the lead screw 4 by a pin.

[0058] The rod 1 is a telescopic rod, and the rod 1 can extend and retract along the axial direction of the rod 1.

[0059] This setting allows the tool to clean different positions of the lead screw 4, improving the tool's adaptability during use.

[0060] The brush head 2 is provided with copper bristles at its end, and the brush head 2 contacts the lead screw 4 through the copper bristles.

[0061] This setting improves the cleaning effectiveness of the tools.

[0062] Example 2 This embodiment provides a device with a lead screw, which uses a tool for cleaning the lead screw as described in Embodiment 1. The tool for cleaning the lead screw is sleeved on the lead screw 4 of the device with the lead screw.

[0063] This setting increases the service life of the lead screw in the equipment.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
