Description

Technical Field

[0001] This utility model relates to the field of building engineering service technology, and in particular to a rust removal device for building engineering services. Background Technology

[0002] Construction engineering services refer to the full-process professional services provided for various construction engineering projects, covering all stages from planning to delivery, and involving multiple fields such as technology, management, and economics.

[0003] Currently, handheld rust removers are commonly used to remove rust from building materials. However, the protective covers of these handheld rust removers are of a fixed size and have a limited protective area. When dealing with large or irregularly shaped materials, the insufficient protective area not only makes it difficult to effectively block the flying iron filings and dust generated during the rust removal process, but may also lead to low efficiency in rust removal operations and even safety hazards and environmental problems. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing technology has handheld rust removers for removing rust from building panels. However, the size of the protective cover is fixed and the protective area is limited. When facing large or irregular panels, the insufficient protection makes it difficult to control the rust splatter, which affects the work efficiency and may bring safety and environmental risks. Therefore, we propose a rust removal device for building engineering services.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rust removal device for construction engineering services, comprising a handheld rod, a rust removal and polishing tool installed at one end of the handheld rod, a protective cover installed on the surface of the handheld rod, a movable groove opened at the top of the protective cover, an extension cover slidably connected inside the movable groove, a handle fixedly connected to the top of the extension cover, a locking groove opened at one end of the protective cover, the number of locking grooves being multiple, a slot opened at one end of the extension cover, a storage spring fixedly connected inside the slot, and a pressing block fixedly connected to one end of the storage spring.

[0006] Preferably, a limiting groove is formed on both sides of the inner cavity of the groove, and a limiting block is fixedly connected to both sides of the pressing block, with the surface of the limiting block slidingly connected to the inside of the limiting groove.

[0007] Preferably, the top of the pressing block is provided with an arc-shaped surface.

[0008] Preferably, the surface of the pressing block is slidably connected to the inside of the slot, and the outer shape of the pressing block matches the inner shape of the slot.

[0009] Preferably, multiple positioning slots are provided at both ends of the inner cavity of the movable slot, and positioning blocks are fixedly connected to both ends of the extension cover, with the surface of the positioning block slidingly connected to the inside of the positioning slot.

[0010] Preferably, a tension spring is fixedly connected to the bottom of the extension cover, and there are multiple tension springs. The bottom of the tension spring is fixedly connected to the bottom of the inner cavity of the moving groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, when a large area of ​​rust needs to be cleaned, the worker pushes the pressing block, causing it to move the energy storage spring into the groove. Then, by moving the position of the extension cover, the extension cover slides inside the moving groove. Once the position is adjusted, the energy storage spring will use its own elasticity to push the pressing block into the corresponding slot, fixing the position of the extension cover. This allows the length of the extension cover to be adjusted according to work requirements, increasing the usable area of ​​the protective cover and improving the practicality of the rust removal device.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0019] Reference Figures 1-4As shown, this utility model provides a technical solution: a rust removal device for construction engineering services, including a handheld rod 1, a rust remover and grinder 2 installed at one end of the handheld rod 1, a protective cover 3 installed on the surface of the handheld rod 1, a movable groove 4 opened on the top of the protective cover 3, an extension cover 5 slidably connected inside the movable groove 4, a handle 7 fixedly connected to the top of the extension cover 5, a locking groove 6 opened at one end of the protective cover 3, the number of locking grooves 6 being multiple, and a slot 8 opened at one end of the extension cover 5, a storage spring 9 fixedly connected inside the slot 8, and a button fixedly connected to one end of the storage spring 9. When a large area of ​​rust needs to be cleaned, the worker pushes the pressing block 10, causing the pressing block 10 to move the energy storage spring 9 into the groove 8. Then, by moving the position of the extension cover 5, the extension cover 5 slides inside the moving groove 4. After the position is adjusted, the energy storage spring 9 will push the pressing block 10 into the corresponding slot 6 through its own elasticity, fixing the position of the extension cover 5. This allows the length of the extension cover 5 to be adjusted according to work requirements, increasing the usable area of ​​the protective cover 3 and improving the practicality of the rust removal device.

[0020] Reference Figure 4 As shown in this embodiment: limit grooves 11 are provided on both sides of the inner cavity of the slot 8, and limit blocks 12 are fixedly connected to both sides of the pressing block 10. The surface of the limit block 12 is slidably connected to the inside of the limit groove 11. By setting the limit groove 11 and the limit block 12, the movement trajectory of the pressing block 10 can be limited to prevent the pressing block 10 from deviating during movement, thus ensuring the stability of the pressing block 10 and further improving the stability of the position of the extension cover 5. This makes the rust removal device more convenient to use and improves work efficiency.

[0021] Reference Figure 3 As shown in this embodiment: the top of the pressing block 10 is provided with an arc-shaped surface 13. By providing the arc-shaped surface 13, when the extension cover 5 drives the pressing block 10 to move upward, and when the pressing block 10 just contacts the slot 6, the pressing block 10 automatically retracts into the slot 8, so that the pressing block 10 can automatically insert into the slot 6, thereby more conveniently and quickly fixing the position of the extension cover 5.

[0022] Reference Figure 2 and Figure 3 As shown in this embodiment: the surface of the pressing block 10 is slidably connected to the inside of the slot 6, and the outer shape of the pressing block 10 matches the inner shape of the slot 6. By setting the pressing block 10 to slide with the slot 6 and the outer shape of the pressing block 10 to match the inner shape of the slot 6, the pressing block 10 can be tightly engaged in the inside of the slot 6, which further improves the stability of the position of the extension cover 5 and avoids the extension cover 5 from shaking during use.

[0023] Reference Figure 2 and Figure 3 As shown in this embodiment: multiple positioning grooves 14 are provided at both ends of the inner cavity of the moving groove 4, and positioning blocks 15 are fixedly connected to both ends of the extension cover 5. The surface of the positioning block 15 is slidably connected to the inside of the positioning groove 14. By setting the positioning groove 14 and the positioning block 15, the positioning block 15 can slide inside the positioning groove 14 during the movement of the extension cover 5, thereby limiting the movement trajectory of the extension cover 5, avoiding the extension cover 5 from deviating during the movement, and further improving the stability of the movement of the extension cover 5.

[0024] Reference Figure 3 As shown in this embodiment: a tension spring 16 is fixedly connected to the bottom of the extension cover 5. There are multiple tension springs 16. The bottom of the tension spring 16 is fixedly connected to the bottom of the inner cavity of the moving groove 4. The tension spring 16 enables the extension cover 5 to move downward quickly by its own elastic force when it is released from the fixation, making it easier and faster for the staff to adjust.

[0025] Working principle: When cleaning a large area of ​​rust, the worker pushes the pressing block 10, causing the pressing block 10 to move the storage spring 9 into the groove 8. Then, by moving the extension cover 5, it slides inside the moving groove 4. Once the position is adjusted, the storage spring 9 uses its own elasticity to push the pressing block 10 into the corresponding slot 6, fixing the position of the extension cover 5. This allows the length of the extension cover 5 to be adjusted according to work requirements, increasing the usable area of ​​the protective cover 3 and improving the practicality of the rust removal device. By setting the limiting groove 11 and the limiting block 12, the movement trajectory of the pressing block 10 can be limited, preventing the pressing block 10 from deviating during movement and ensuring its stability. This further improves the stability of the extension cover 5, making the rust removal device more convenient to use and improving work efficiency. The arc-shaped surface 13 ensures that when the extension cover 5 moves the pressing block 10 upwards, the pressing block 10 is just touching the slot... When contact is made, the pressing block 10 automatically retracts into the groove 8, allowing it to automatically insert into the slot 6. This makes it easier and faster to fix the position of the extension cover 5. By setting the pressing block 10 to slide in the slot 6, and by matching the external shape of the pressing block 10 with the internal shape of the slot 6, the pressing block 10 can be tightly engaged in the slot 6, further improving the stability of the extension cover 5 and preventing it from shaking during use. By setting the positioning groove 14 and the positioning block 15, the positioning block 15 can slide inside the positioning groove 14 during the movement of the extension cover 5, thereby limiting the movement trajectory of the extension cover 5 and preventing it from deviating during movement. This further improves the stability of the extension cover 5. The tension spring 16 allows the extension cover 5 to move downward quickly when it is released from its fixed position, making it easier and faster for the operator to adjust.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
