Description

Technical Field

[0001] This utility model relates to the field of roller brush technology, and in particular to a telescopic coating rod for efficient coating. Background Technology

[0002] A roller brush, also known as a paint roller, is a commonly used painting tool. It mainly consists of a handle, a connecting rod, and a roller. The handle is easy to grip and operate. The connecting rod connects the handle and the roller, allowing the operator to paint from a certain distance. The roller is the core component, usually consisting of a cylindrical roller core and absorbent materials such as bristles or sponge wrapped around it.

[0003] Currently, roller brush handles are usually of a fixed length. When faced with painting tasks at higher positions, operators need to use auxiliary equipment such as ladders and scaffolding, or it is difficult to reach specific areas for painting due to the fixed length of the tool. This limits the use of roller brushes and fails to meet diverse painting needs.

[0004] In response to the technical problem that the fixed length of the roller brush handle makes it difficult to meet the needs of painting tasks at different heights, this application proposes a telescopic coating rod for efficient painting. Utility Model Content

[0005] To address the problem that existing roller brushes have fixed handle lengths, making it difficult to meet the needs of painting tasks at different heights, this application provides a telescopic coating rod for efficient painting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency telescopic coating rod, comprising a connecting rod, a telescopic rod slidably connected to the outer wall of the connecting rod, a screw rotatably connected to the inner wall of the connecting rod, the screw being connected to the telescopic rod via a pressing assembly, a connecting seat being provided at the top of the telescopic rod, a fixing block being fixedly connected to the bottom of the connecting seat, a fixing groove being provided at the top of the telescopic rod, the outer wall of the fixing block fitting the shape of the inner wall of the fixing groove, slots being provided on both the left and right sides of the outer wall of the fixing block, and a second knob rotatably connected to the outer wall of the telescopic rod, the second knob being connected to the slots via a snap-fit ​​assembly.

[0007] As a further improvement of this utility model, the extrusion assembly includes a threaded sleeve that is threadedly connected to the outer wall of the screw, the outer wall of the threaded sleeve is slidably connected to the inner wall of the connecting rod, and an extrusion block is fixedly connected to the top end of the threaded sleeve.

[0008] As a further improvement of this utility model, pressure blocks are provided on both the left and right sides of the top of the extrusion block, the outer wall of the pressure block is slidably connected to the inner wall of the connecting rod, and the outer side of the pressure block is pressed against the inner wall of the telescopic rod.

[0009] As a further improvement of this utility model, the snap-fit ​​assembly includes control plates fixedly connected to both sides of the inner wall of the second knob. Each control plate has a rotating plate at one end and a snap-fit ​​block at one end of each rotating plate. The outer wall of the snap-fit ​​block fits the shape of the inner wall of the snap-fit ​​slot.

[0010] As a further improvement of this utility model, the inner wall of the rotating plate is rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is fixedly connected to the inner wall of the telescopic rod.

[0011] As a further improvement of this utility model, springs are fixedly connected to the opposite ends of the rotating plates on both the left and right sides, and the opposite ends of the springs are fixedly connected to the inner wall of the telescopic rod.

[0012] As a further improvement of this utility model, the bottom end of the connecting rod is rotatably connected to a first knob, and the bottom end of the screw is fixedly connected to the top end of the first knob.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. In this utility model, by rotating the first knob, the screw is driven to rotate, thereby causing the threaded sleeve to move the extrusion block downward, so that the extrusion block no longer squeezes the pressure block, and thus the pressure block no longer squeezes the inner wall of the telescopic rod. This allows the position of the telescopic rod to be adjusted, changing the overall length of the rod, and enabling it to reach different heights and positions for painting, greatly saving time and effort.

[0015] 2. In this utility model, by rotating the second knob, the control plates on both sides drive the rotating plate to rotate, thereby causing the inner side of the rotating plate to rotate outward, moving the locking block out of the locking groove on the fixing block, so that the connecting seat can be removed for replacement of the coating head. When the coating head is worn or damaged, only the coating head needs to be replaced without replacing the entire coating rod, reducing the overall replacement cost of the device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] Example 1: Refer to Figure 1 and Figure 2 A high-efficiency telescopic coating rod includes a connecting rod 1, a telescopic rod 2 slidably connected to the outer wall of the connecting rod 1, a screw 4 rotatably connected to the inner wall of the connecting rod 1, a threaded sleeve 5 threadedly connected to the outer wall of the screw 4, the outer wall of the threaded sleeve 5 slidably connected to the inner wall of the connecting rod 1, a pressing block 6 fixedly connected to the top of the threaded sleeve 5, pressure blocks 7 provided on both the left and right sides of the top of the pressing block 6, the outer wall of the pressure blocks 7 slidably connected to the inner wall of the connecting rod 1, the outer side of the pressure blocks 7 pressing against the inner wall of the telescopic rod 2, a first knob 3 rotatably connected to the bottom end of the connecting rod 1, and the bottom end of the screw 4 fixedly connected to the top of the first knob 3.

[0030] Specifically, multiple protrusions are fixedly connected to the outer walls of the first knob 3 and the second knob 12. The protrusions facilitate the rotation of the first knob 3 and the second knob 12. Both sides of the pressing block 6 are inclined surfaces, and the corners of the left and right pressure blocks 7 are also inclined surfaces. The contact between the inclined surfaces facilitates the pressing block 6 to press the pressure blocks 7 to both sides.

[0031] Example 2: Refer to Figures 3-5 The telescopic rod 2 has a connecting seat 8 at its top end, and a fixing block 9 is fixedly connected to the bottom end of the connecting seat 8. A fixing groove 10 is opened at the top end of the telescopic rod 2. The outer wall of the fixing block 9 fits the inner wall of the fixing groove 10. Slots 11 are opened on both the left and right sides of the outer wall of the fixing block 9. A second knob 12 is rotatably connected to the outer wall of the telescopic rod 2. A control plate 13 is fixedly connected to both sides of the inner wall of the second knob 12. A rotating plate 14 is set at one opposite end of the control plate 13. A locking block 16 is fixedly connected to one opposite end of the rotating plate 14. The outer wall of the locking block 16 fits the inner wall of the locking groove 11. A rotating shaft 15 is rotatably connected to the inner wall of the rotating plate 14. The outer wall of the rotating shaft 15 is fixedly connected to the inner wall of the telescopic rod 2. Springs 17 are fixedly connected to the opposite ends of the left and right rotating plates 14. Springs 17 are fixedly connected to the opposite ends of the opposite ends of the telescopic rod 2.

[0032] Specifically, when installing a new coating head, first turn the second knob 12. The second knob 12 will drive the control plate 13 to move, thereby causing the rotating plate 14 to rotate. The rotating plate 14 rotates on the outer wall of the rotating shaft 15, causing the center side of the rotating plate 14 to move the locking block 16 away from the center of the telescopic rod 2. At the same time, the rotating plate 14 compresses the spring 17. Then, the fixing block 9 on the new connecting seat 8 is inserted into the fixing groove 10. Release the second knob 12, and the spring 17 rebounds the rotating plate 14, moving the locking block 16 into the groove 11 and fixing the connecting seat 8.

[0033] Working principle: When adjusting the overall length of the coating rod, first turn the first knob 3. The first knob 3 drives the screw 4 to rotate, which in turn drives the threaded sleeve 5 to move downward. The threaded sleeve 5 then drives the pressing block 6 to move downward, so that the pressing block 6 no longer presses against the pressure blocks 7 on both sides. This prevents the outer side of the pressure blocks 7 from pressing against the inner wall of the telescopic rod 2, allowing the telescopic rod 2 to move on the outer wall of the connecting rod 1. This allows the overall length of the coating rod to be adjusted, enabling it to reach different heights and positions for coating, greatly saving time and effort. When the coating head is damaged, turn the second knob 12. The second knob 12 drives the control plate 13 to move, causing the control plate 13 to rotate the outer side of the rotating plate 14. The end of the rotating plate 14 closest to the center moves to both sides, causing the locking block 16 to disengage from the locking groove 11 on the fixing block 9. This allows the fixing block 9 to be moved out of the fixing groove 10 at the top of the telescopic rod 2 for replacement.

[0034] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
