Technical Field
[0001] This utility model relates to the field of toilet brush technology, specifically to a clamping structure for a toilet brush with a groove-shaped replaceable brush head. Background Technology
[0002] As an everyday household item, the convenience and hygiene of toilet brushes are paramount. Currently, most toilet brushes on the market have fixed brush heads, which are prone to getting dirty and harboring bacteria; some replaceable brush heads also have complex clamping structures and high manufacturing costs. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides a clamping structure for a toilet brush with a groove-shaped replaceable brush head, which is simple in structure, easy to use, and low in cost.
[0004] The technical solution is as follows: a clamping structure for a toilet brush with a replaceable brush head in the shape of a sliding groove, comprising a brush rod, a movable guide rod disposed inside the brush rod, a control component for controlling the movement of the guide rod disposed on the brush rod, and a brush head mounting hole opened at the bottom of the brush rod. The guide rod is connected to a return spring, and a limit block is disposed at the bottom of the guide rod. Two limit grooves are opened on the limit block, the upper part of which is arc-shaped and the lower end is vertical. Two brush head clamping shafts are disposed inside the brush rod near the brush head mounting hole. Brush head clamps are rotatably mounted on the brush head clamping shafts. A limit head located within the limit groove is disposed at the upper part of the brush head clamp, and a spherical mating part for the brush head is disposed at the lower part of the brush head clamp.
[0005] A further feature is that a spring mounting frame is provided on the guide rod, a limiting plate passing through the spring mounting frame is provided inside the brush rod, and the two ends of the reset spring abut against the top of the spring mounting frame and the limiting plate, respectively.
[0006] The brush rod is formed by inserting an upper rod and a lower rod together, and the lower rod is formed by splicing a front half rod and a rear half rod together;
[0007] The control component is a push button. The upper rod has a push button mounting groove, and the push button mounting groove has a through hole. The back of the push button passes through the through hole and is connected to the guide rod.
[0008] The upper part of the brush head clamp is provided with a groove, and the inner walls on both sides of the groove are provided with the limiting head. The limiting block has two limiting grooves on both sides.
[0009] The brush rod has a guide ring installed inside that cooperates with the guide rod.
[0010] With this invention, the guide rod drives the limiting block to move up and down, and the arc-shaped limiting groove and the limiting head work together to open and close the two brush head clamps, making it convenient to replace the brush head. The structure is simple, easy to use, and low in cost. Attached Figure Description

[0018] See Figures 1 to 3 As shown, a clamping structure for a toilet brush with a groove-shaped replaceable brush head includes a brush rod 1 and a replaceable brush head 8. A movable guide rod 2 is disposed inside the brush rod 1. A control component for controlling the movement of the guide rod 2 is disposed on the brush rod 1. In this embodiment, the control component is a push button 3. The brush rod 1 is formed by inserting an upper rod 11 and a lower rod 12. The lower rod 12 is formed by splicing a front half rod 121 and a rear half rod 122. A push button mounting groove 111 is provided on the upper rod 11, and a through hole 112 is provided inside the push button mounting groove 111. The back of the push button 3 passes through the through hole 112 and connects to the guide rod 2. Pushing the push button 3 moves the guide rod 2. A guide ring 13 that cooperates with the guide rod 2 is installed inside the brush rod 1 to ensure that the guide rod 2 can move stably without shaking.
[0019] The bottom of the brush rod 1 has a brush head mounting hole 6, and the guide rod 2 has a spring mounting frame 21. The brush rod 1 has a limiting plate 14 that passes through the spring mounting frame 21. The two ends of the reset spring 4 abut against the top of the spring mounting frame 21 and the limiting plate 14, respectively. When the push button 3 is pushed down, the reset spring 4 is compressed and the guide rod 2 moves down. After the push button 3 is released, the reset spring 4 pushes the guide rod 2 to reset.
[0020] The bottom of the guide rod 2 is provided with a limiting block 5. The limiting block 5 has two symmetrically arranged limiting grooves 51 on both sides. The brush rod 1 is provided with two brush head clamping shafts 15 near the brush head mounting hole 6. The brush head clamps 7 are rotatably mounted on the brush head clamping shafts 15. The upper part of the brush head clamp 7 is provided with a groove. The inner walls of both sides of the groove are provided with limiting heads 71. The limiting heads 71 cooperate with the limiting grooves 51 and are located in the limiting grooves 51. The lower part of the brush head clamp 7 is provided with a brush head spherical mating part 72.
[0021] See Figure 4 and Figure 5 As shown, when the push button 3 is not pushed, the reset spring 4 is in the natural state and the limit block 5 is in the high position. At this time, the limit head 71 is located at the vertical end of the limit slide 51. When the two brush head clamps 7 are pulled downward by the brush head, the limit head 71 will be subjected to the lateral force of the vertical end of the limit slide 51, so that it will not pull down the limit slide 51, thereby ensuring that the brush head clamps 7 are in the retracted state.
[0022] See Figure 6 and Figure 7 As shown, pushing the push button 3 downwards compresses the return spring 4, causing the guide rod 2 to move downwards. The limiting block 5 then moves to its lowest position, at which point the limiting head 71 is located at the end of the arc-shaped limiting groove 51. During this process, the limiting head 71 is restricted by the arc-shaped limiting groove 51, and the two brush head clamps 7 open outwards, releasing the brush head that was originally clamped or preparing to clamp a new brush head. After releasing the push button 3, the two brush head clamps 7 retract again under the action of the return spring.
