Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of decoration engineering, and specifically relates to a hand tool for decoration engineering. BACKGROUND

[0002] Decoration engineering generally refers to a series of construction activities for beautifying, protecting and improving the function of the interior or exterior of a building. These activities may include wall treatment, floor laying, ceiling decoration, lighting installation, furniture arrangement, etc. The purpose of decoration engineering is to improve the aesthetics, functionality and comfort of the space, and may also involve improving energy efficiency and safety. In order to cope with different decoration operations, different tools are used.

[0003] As disclosed in the publication No. CN216552924U, a ceramic tile clamping tool for decoration engineering is disclosed, comprising a connecting seat, a guide hole, an adjustable clamping jaw, a groove, a fixed handle and a linkage mechanism. The utility model has the advantages of reasonable and simple structure, low production cost, convenient installation and complete functions. The plug-in pin can quickly clamp the corresponding clamping groove on the telescopic arm through the lower locking tongue, thereby improving the efficiency of adjusting and fixing. In the utility model, the fixed handle and the movable handle are held by hand, so that the linkage seat can be moved upward as a whole by the movable handle, and the upward movement of the linkage seat can drive all adjustable clamping jaws to move inward through the connecting rod, thereby improving the reliability of the ceramic tile clamping.

[0004] However, in actual use, it is found that: in the process of general house decoration, the first step is to paint the wall, which is usually completed manually. However, during the painting process, since the person is painting on the ground, the painting tool often cannot be turned in the actual operation when encountering corners and other details, thereby making the whole process very laborious and inefficient. Therefore, in actual use, the painting tool needs to be designed with a fine-tuning function. UTILITY MODEL CONTENTS

[0005] The purpose of the present application is to solve the problem of designing a painting tool with a fine-tuning function as mentioned above, and to provide a hand tool for decoration engineering.

[0006] The technical solution adopted by the present application is as follows: a hand tool for decoration engineering, a roller shaft is rotatably inserted into the side surface of the roller, an insertion rod is inserted into the side surface of one end of the roller shaft opposite the roller, a rotation limiting bolt is arranged on the side surface of the insertion rod, a swing connecting shaft is inserted into the side surface of one end of the insertion rod opposite the roller, a telescopic slide rod is fixedly inserted into the side surface of one end of the swing connecting shaft opposite the insertion rod, and a swing limiting bolt is arranged on the side surface of one end of the insertion rod opposite the rotation limiting bolt.

[0007] By adopting the above technical solution, the operator uses the roller's central shaft as an interlocking structure and the roller itself as the painting roller structure. The roller can rotate on the interlocking rod, and its rotation is controlled by a rotation limit bolt. In the connection between the interlocking rod and the swing connecting shaft, the interlocking rod can rotate on the swing connecting shaft, while the swing connecting shaft and the telescopic slide rod cannot rotate. Therefore, the component used to fix the rotation of the interlocking rod is the swing limit bolt. With this structure, the operator can change the angle of the painting roller component during use, thus adapting to the actual painting conditions of various walls. The adjustment structure is simple, easy to maintain, and relatively labor-saving during use.

[0008] The roller shaft and roller, as roller components, are mainly used to evenly apply the paint coating to the wall surface. The roller shaft can be initially rotated using the plug rod and rotation limit bolt, which can be used to switch between various painting angles.

[0009] The interaction between the connector rod and the swing-connecting shaft gives the connector rod a swing function, thereby better driving the roller's central shaft and roller components to achieve painting. Furthermore, the entire structure is simple and easy to operate and maintain.

[0010] In a preferred embodiment, the side surface of the telescopic slide rod is provided with a plurality of limiting holes, and a lifting hollow rod is inserted into one end of the telescopic slide rod relative to the swing connecting shaft. A plurality of guide slot plates are fixedly connected to the side surface of the lifting hollow rod, and the guide slot plates are slidably inserted with plugs through the provided slots.

[0011] By adopting the above technical solution, the sliding connection between the telescopic slide rod and the lifting hollow rod gives the entire device the function of telescopic movement. After telescopic movement, it solves the problem of operators being unable to reach walls, ceilings, and other distant objects while standing on the ground. The guide plate on the lifting hollow rod serves as a connecting component, allowing the connector to be inserted downwards, thereby connecting the connector to the limiting hole and achieving the limiting and fixing of telescopic movement.

[0012] In a preferred embodiment, a plurality of extension rods are fixedly connected to the side surface of the connector, and a sliding limit screw is fixedly inserted into the side surface of the extension rod.

[0013] By adopting the above technical solution, the extension rod is used as an extension structure, and its main function is to connect the sliding limit screw. The sliding limit screw, as the connecting and operating component, mainly serves to fix the connector when it is inserted and limited, preventing it from slipping off during operator operation.

[0014] In a preferred embodiment, the side surface of the guide plate is provided with a sliding groove.

[0015] By adopting the above technical solution, a sliding groove is used as a component to accommodate and place a sliding limit screw for sliding operation.

[0016] In a preferred embodiment, a limiting nut is inserted into the side surface of the sliding limiting screw.

[0017] By adopting the above technical solution, the interaction between the limiting nut and the sliding limiting screw is utilized to increase the friction between the limiting nut and the guide plate during tightening, thereby achieving the overall limiting effect.

[0018] In a preferred embodiment, a handle is fixedly connected to one end of the hollow lifting rod relative to the telescopic slide rod.

[0019] By adopting the above technical solution, the handle is used as the handheld part for the operator.

[0020] In a preferred embodiment, an auxiliary handle is fixedly connected to the side surface of the lifting hollow rod.

[0021] By adopting the above technical solution, an auxiliary handle is used as an auxiliary hand-held component to facilitate operation.

[0022] In a preferred embodiment, a device strap is fixedly connected to the side surface of the lifting hollow rod.

[0023] By adopting the above technical solution, the device strap is used as the strap component of the entire device, making it convenient for the operator to carry.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0025] In this application, a roller shaft is used as an interlocking structure, and the roller is used as a painting roller structure. The roller is inserted into the connecting rod, allowing it to rotate on the connecting rod, with rotation control using a rotation limit bolt. In the connection between the connecting rod and the swing connecting shaft, the connecting rod can rotate on the swing connecting shaft, while the swing connecting shaft and the telescopic slide rod cannot rotate. Therefore, the component used to fix the rotation of the connecting rod is the swing limit bolt.

[0026] The roller shaft and roller, as roller components, are mainly used to evenly apply the paint coating to the wall surface. The roller shaft can be initially rotated using the plug rod and rotating limit bolt, which can be used to switch between various painting angles.

[0027] The interaction between the connector rod and the swing-connecting shaft gives the connector rod a swing function, thereby better driving the roller's central shaft and roller components to achieve painting. Furthermore, the entire structure is simple and easy to operate and maintain. Attached Figure Description

[0035] Example: A decorative engineering hand tool, wherein a roller 2 is rotatably inserted into the side surface of the roller shaft 1, a connecting rod 3 is inserted into the side surface of the roller shaft 1 relative to the roller 2, a rotation limit bolt 4 is provided on the side surface of the connecting rod 3, a swing connecting shaft 5 is inserted into the side surface of the connecting rod 3 relative to the roller 2, a telescopic slide rod 6 is fixedly inserted into the side surface of the swing connecting shaft 5 relative to the side surface of the connecting rod 3, and a swing limit bolt 7 is provided on the side surface of the connecting rod 3 relative to the rotation limit bolt 4.

[0036] The operator uses the central shaft 1 of the roller as an interlocking structure and roller 2 as the painting roller structure. The roller 2 is connected to the connecting rod 3, allowing it to rotate on the connecting rod 3, with rotation control using the rotation limit bolt 4. The connecting rod 3 is connected to the swing connecting shaft 5, allowing it to rotate on the swing connecting shaft 5, while the swing connecting shaft 5 cannot rotate with the telescopic slide rod 6. Therefore, the component used to fix the rotation of the connecting rod 3 is the swing limit bolt 7. Through this structure, the operator can change the angle of the painting roller components to adapt to various wall painting conditions. The adjustment structure is simple, easy to maintain, and relatively labor-saving during use.

[0037] The roller shaft 1 and roller 2 are roller components, mainly used to evenly brush the paint coating onto the wall surface. The roller shaft 1 can be initially rotated using the plug rod 3 and the rotation limit bolt 4, which can be used to switch between various painting angles.

[0038] The interaction between the plug rod 3 and the swing connecting shaft 5 gives the plug rod 3 a swing function, thereby better driving the roller central shaft 1 and roller 2 components to achieve painting. Moreover, the whole structure is simple and easy to operate and maintain.

[0039] Multiple limiting holes 8 are provided on the side surface of the telescopic slide rod 6. A lifting hollow rod 9 is inserted into the side surface of one end of the telescopic slide rod 6 relative to the swing connecting shaft 5. Multiple guide plates 10 are fixedly connected to the side surface of the lifting hollow rod 9. The guide plates 10 are slidably inserted into the plugs 11 through the holes and slots.

[0040] The sliding connection between the telescopic slide rod 6 and the lifting hollow rod 9 gives the entire device the telescopic function. After telescopic extension, it solves the problem of the operator being unable to reach the wall or ceiling from the ground. The guide plate 10 on the lifting hollow rod 9 serves as a connecting component to connect the connector 11 downwards, thereby connecting the connector 11 to the limiting hole 8 to achieve the limiting and fixing of telescopic extension.

[0041] Multiple extension rods 12 are fixedly connected to the side surface of the connector 11, and sliding limit screws 13 are fixedly inserted into the side surface of the extension rods 12. The extension rods 12 serve as extension structures, and their main function is to connect the sliding limit screws 13. The sliding limit screws 13, as connecting and operating components, mainly serve to fix the connector 11 when it is inserted and limited, preventing it from slipping out during operator operation.

[0042] The side surface of the guide plate 10 is provided with a sliding groove 14. The sliding groove 14 serves as a component for accommodating and placing the sliding limit screw 13 for sliding operation.

[0043] A limiting nut 15 is inserted into the side surface of the sliding limiting screw 13. By utilizing the interaction between the limiting nut 15 and the sliding limiting screw 13, the friction between the limiting nut 15 and the guide plate 10 is increased when tightening, thereby achieving the overall limiting function.

[0044] A handle 16 is fixedly connected to one end of the hollow lifting rod 9 relative to the telescopic slide rod 6. The handle 16 is used as a handheld part for the operator.

[0045] An auxiliary handle 17 is fixedly connected to the side surface of the lifting hollow rod 9. The auxiliary handle 17 serves as a hand-held component for the operator's convenience.

[0046] A device shoulder strap 18 is fixedly connected to the side surface of the lifting hollow rod 9. The device shoulder strap 18 serves as the shoulder strap component of the entire device, making it convenient for the operator to carry.

[0047] The implementation principle of this embodiment of a decorative engineering hand tool is as follows: The operator uses the central shaft 1 of the roller as an interlocking structure and the roller 2 as the painting roller structure. The roller 2 is connected to the connecting rod 3, allowing the roller 2 to rotate on the connecting rod 3, and the rotation is controlled by the rotation limit bolt 4. In the connection between the connecting rod 3 and the swing connecting shaft 5, the connecting rod 3 can rotate on the swing connecting shaft 5, while the swing connecting shaft 5 cannot rotate with the telescopic slide rod 6. Therefore, the component used to fix the rotation of the connecting rod 3 is the swing limit bolt 7. Through this structure, the operator can change the angle of the painting roller component during use, thereby adapting to the actual painting conditions of various walls. The adjustment structure is simple, easy to maintain, and saves physical effort during use.

[0048] The roller shaft 1 and roller 2 are roller components, mainly used to evenly brush the paint coating onto the wall surface. The roller shaft 1 can be initially rotated using the plug rod 3 and the rotation limit bolt 4, which can be used to switch between various painting angles.

[0049] The interaction between the plug rod 3 and the swing connecting shaft 5 gives the plug rod 3 a swing function, thereby better driving the roller central shaft 1 and roller 2 components to achieve painting. Moreover, the whole structure is simple and easy to operate and maintain.
