Description

Technical Field

[0001] This utility model relates to the field of paint application technology, and in particular to a telescopic pole type aerial paint applicator. Background Technology

[0002] In paint application, especially when working on high walls and ceilings, traditional painting tools often suffer from fixed or inconvenient lengths. If the tool is too short, workers need to use ladders, scaffolding, or other auxiliary equipment to climb, which not only increases the danger of the work but also reduces efficiency due to frequent movement of equipment. If the tool length cannot be flexibly adapted to different height requirements, it is difficult to ensure the uniformity and quality of the paint application at heights, causing many inconveniences to the construction process.

[0003] Currently, most adjustable-length applicators use a screw-type telescopic structure. While this structure allows for locking and fixing after any length adjustment, the entire adjustment process is too cumbersome, requiring operators to continuously rotate the screw. Therefore, there is an urgent need for a telescopic pole-type aerial paint applicator to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a telescopic pole-type aerial paint applicator. Its advantages include: it allows for quick locking and fixing of the applicator after adjustment to any length, meeting the needs of users with applicators of different lengths.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A telescopic pole-type aerial paint applicator includes a fixed cylinder, a movable column inserted inside the fixed cylinder, a rotating seat fixedly connected to one end of the movable column extending outside the fixed cylinder, and application brushes rotatably connected to the inner walls of both sides of the rotating seat. A locking shell is fixedly connected to the outer circumference of the fixed cylinder, and a positioning component for fixing and locking the movable column is provided inside the locking shell.

[0007] The above technical solution allows for the quick and easy locking of the movable column using the positioning components inside the locking housing, preventing it from sliding during use. The rotating brushes connected to both sides of the rotating seat can be flexibly adjusted to facilitate paint application to different areas such as high walls and ceilings.

[0008] Preferably, the positioning assembly includes a second rotating column rotatably connected to the outer circumferential wall of the locking housing. A worm gear is fixedly connected to one end of the second rotating column inside the locking housing. A worm wheel meshes with the outer circumferential wall of the worm gear. A first rotating column is fixedly connected to the inner circumferential wall of the worm wheel. A first gear disc is fixedly connected to the outer circumferential wall of the first rotating column. A rack meshes with the outer circumferential wall of the first gear disc. A slide is fixedly connected to the inner circumferential wall of the locking housing. The rack slides inside the slide. A clamping ring plate for clamping the movable column is fixedly connected to one end of the rack.

[0009] The above technical solutions enable rapid locking and fixing of the movable column, making operation simple and efficient, and solving the problem of cumbersome adjustment in traditional screw-type telescopic structures.

[0010] Preferably, a soft pad is fixedly connected to the inner circumferential wall of the clamping ring plate, and a spiral groove is formed on the outer circumferential wall of the movable column.

[0011] The above technical solutions further improve the locking effect of the clamping ring plate on the movable column, effectively preventing the movable column from sliding relative to each other when under force, and ensuring the stability of the coating operation.

[0012] Preferably, a second gear disk is fixedly connected to the outer circumference of the first rotating column, and a toothed ring bar meshes with the outer circumference of the second gear disk.

[0013] The above technical solutions enable the synchronous movement of multiple first rotating columns, ensuring that multiple clamping ring plates can simultaneously clamp the movable column, thus improving the uniformity and reliability of locking.

[0014] Preferably, the number of first rotating columns inside the locking housing is four, and the first gear disks fixed to the outer circumference of the four first rotating columns are all engaged with the gear ring bar.

[0015] The above technical solution enables four clamping ring plates to clamp the movable column simultaneously from different directions, ensuring that the movable column is subjected to uniform force and preventing damage to the movable column due to excessive local force.

[0016] Preferably, the inner circumferential wall of the locking shell is fixedly connected to a guide seat for ensuring the stable rotation of the toothed ring bar, and the toothed ring bar passes through the inside of the guide seat.

[0017] The above technical solutions ensure that the toothed ring maintains a stable trajectory during rotation, preventing it from shifting or wobbling, and ensuring smoother and more reliable meshing transmission between it and the second gear disc, thereby guaranteeing the normal operation of the positioning components.

[0018] Preferably, an anti-slip sleeve is fixedly connected to the outer circumferential wall of the fixed cylinder, and a rotating block is fixedly connected to one end of the second rotating column extending to the outside of the fixed cylinder.

[0019] Through the above technical solutions, the anti-slip sleeve can increase the friction between the operator's hand and the fixed cylinder, preventing the device from slipping due to sweaty hands or excessive force during use, thus improving operational safety.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. A telescopic pole type high-altitude paint applicator, the overall length of which can be flexibly adjusted by pulling the movable column to meet different high-altitude painting needs, and the positioning component can achieve a stable locking. Specifically, by rotating the rotating block, a series of components such as the worm gear and worm wheel are driven to make the clamping ring plate clamp the movable column. The soft pad on the inner wall of the clamping ring plate and the spiral groove on the outer wall of the movable column greatly improve the locking effect, effectively prevent the movable column from sliding during use, and enhance the stability of the device.

[0022] 2. A telescopic pole type high-altitude paint applicator, which drives four first rotating columns to move synchronously with the second gear disk on the first rotating column meshing with the toothed ring rack and with the assistance of the guide seat. This allows the four clamping ring plates to evenly clamp the movable column, avoiding damage to the movable column or failure of locking due to uneven force, thereby extending the service life of the device and ensuring its long-term stable operation.

Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0032] Reference Figures 1-4 A telescopic pole-type high-altitude paint applicator includes a fixed cylinder 1, a movable column 4 inserted inside the fixed cylinder 1, a rotating seat 3 fixedly connected to one end of the movable column 4 extending outside the fixed cylinder 1, and painting brushes 2 rotatably connected to both inner walls of the rotating seat 3. A locking shell 6 is fixedly connected to the outer circumference of the fixed cylinder 1, and a positioning component for fixing and locking the movable column 4 is provided inside the locking shell 6. The operator can adjust the overall length of the fixed cylinder 1 and the movable column 4 by pulling the movable column 4 to adapt to the painting needs of different heights. When adjusted to a suitable length, the positioning component inside the locking shell 6 can quickly fix and lock the movable column 4 to prevent the movable column 4 from sliding during use. The painting brushes 2 rotatably connected to both sides of the rotating seat 3 can flexibly adjust their angles to facilitate paint application to different areas such as high walls and ceilings.

[0033] Furthermore, the positioning assembly includes a second rotating column 20 rotatably connected to the outer circumferential wall of the locking housing 6. A worm gear 18 is fixedly connected to one end of the second rotating column 20 inside the locking housing 6. A worm wheel 19 meshes with the outer circumferential wall of the worm gear 18. A first rotating column 12 is fixedly connected to the inner circumferential wall of the worm wheel 19. A first gear disc 11 is fixedly connected to the outer circumferential wall of the first rotating column 12. A rack 10 meshes with the outer circumferential wall of the first gear disc 11. A slide 9 is fixedly connected to the inner circumferential wall of the locking housing 6. The rack 10 slides inside the slide 9, and one end of the rack 10 is fixed. A clamping ring plate 16 is connected to clamp the movable column 4. When it is necessary to fix the movable column 4, the second rotating column 20 is rotated to drive the worm gear 18 to rotate. The worm gear 18 meshes with the worm wheel 19 to drive the first rotating column 12 to rotate. The first gear disk 11 on the first rotating column 12 meshes with the rack 10. Under the guidance of the slide 9, the rack 10 drives the clamping ring plate 16 to approach the movable column 4 and clamp it, thereby realizing the quick locking and fixing of the movable column 4. The operation is simple and efficient, and it solves the problem of cumbersome adjustment of the traditional screw-type telescopic structure.

[0034] Furthermore, a soft pad 17 is fixedly connected to the inner circumference of the clamping ring plate 16, and a spiral groove 5 is provided on the outer circumference of the movable column 4. The soft pad 17 on the inner wall of the clamping ring plate 16 can increase the friction between it and the movable column 4. At the same time, the spiral groove 5 on the outer circumference of the movable column 4 can form a better engagement with the soft pad 17, further improving the locking effect of the clamping ring plate 16 on the movable column 4, effectively preventing the movable column 4 from sliding relative to each other when under force, and ensuring the stability of the coating operation.

[0035] Furthermore, a second gear disk 13 is fixedly connected to the outer circumference of the first rotating column 12. A toothed ring bar 14 meshes with the outer circumference of the second gear disk 13. When the first rotating column 12 rotates, the second gear disk 13 on its outer circumference rotates synchronously. The second gear disk 13 meshes with the toothed ring bar 14, which can drive the toothed ring bar 14 to rotate, thereby realizing the synchronous movement of multiple first rotating columns 12. This ensures that multiple clamping ring plates 16 can clamp the movable column 4 simultaneously, improving the uniformity and reliability of locking.

[0036] Furthermore, the number of first rotating pillars 12 inside the locking shell 6 is four. The first gear disks 11 fixed to the outer circumference of the four first rotating pillars 12 are all engaged with the gear ring 14. The first gear disks 11 on the outer circumference of the four first rotating pillars 12 are all engaged with the gear ring 14, so that under the transmission action of the gear ring 14, the four first rotating pillars 12 can rotate synchronously, thereby driving the four clamping ring plates 16 to clamp the movable pillar 4 from different directions at the same time, so that the movable pillar 4 is subjected to uniform force and avoids damage to the movable pillar 4 due to excessive local force.

[0037] Furthermore, a guide seat 15 is fixedly connected to the inner circumference of the locking housing 6 to ensure the stable rotation of the toothed ring 14. The toothed ring 14 passes through the inside of the guide seat 15, which supports and guides the toothed ring 14, ensuring that the toothed ring 14 maintains a stable trajectory during rotation, preventing the toothed ring 14 from deviating or shaking, and ensuring smoother and more reliable meshing transmission between it and the second gear disk 13, thereby ensuring the normal operation of the positioning assembly.

[0038] Furthermore, an anti-slip sleeve 8 is fixedly connected to the outer circumference of the fixed cylinder 1, and a rotating block 7 is fixedly connected to one end of the second rotating column 20 extending to the outside of the fixed cylinder 1. The anti-slip sleeve 8 on the outer circumference of the fixed cylinder 1 can increase the friction between the operator's hand and the fixed cylinder 1, preventing the device from slipping due to sweaty hands or excessive force during use, thus improving the safety of operation. The rotating block 7 at the end of the second rotating column 20 makes it easier for the operator to rotate the second rotating column 20, making the adjustment operation more labor-saving and convenient.

[0039] Working principle: During use, the operator can adjust the overall length of the fixed cylinder 1 and the movable column 4 by pulling the movable column 4 to adapt to different high-altitude application needs. Once the length is determined, the operator rotates the rotating block 7, which drives the second rotating column 20 and the worm gear 18 to rotate. The worm gear 18 meshes with the worm wheel 19 to drive the first rotating column 12 to rotate, which in turn drives the first gear disk 11 to rotate. The first gear disk 11 meshes with the rack 10. Under the guidance of the slide 9, the rack 10 drives the clamping ring plate 16 to approach and clamp the movable column 4. The soft pad 17 on the inner wall of the clamping ring plate 16 can increase the friction with the movable column 4. Combined with the spiral groove 5 on the outer wall of the movable column 4, it can significantly improve the locking effect, prevent the movable column 4 from sliding during use, and enhance the stability of the device.

[0040] Meanwhile, the second gear disk 13 on the first rotating column 12 meshes with the gear ring 14. With the assistance of the guide seat 15, it can drive the four first rotating columns 12 to move synchronously, so that the four clamping ring plates 16 can evenly clamp the movable column 4, avoiding damage to the movable column 4 or failure of locking due to uneven force, thus extending the service life of the device. In addition, the anti-slip sleeve 8 on the outer wall of the fixed cylinder 1 can increase the friction between the hand and the device, prevent slipping during use, and improve the safety and convenience of operation.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
