A carpet edge puller

Abstract

This utility model discloses a carpet edge-pulling and wrinkle-preventing device, including a first fixed end and a second fixed end. A fixed beam is fixedly connected to the first fixed end, and a fixed box that slides with the fixed beam is fixedly connected to the second fixed end. It also includes a drive mechanism disposed within the second fixed end. The drive mechanism includes a motor and a second hammer plate. When the motor operates, it drives the second hammer plate to reciprocate, causing the second hammer plate to repeatedly strike the first hammer plate at the inner end of the fixed beam. This causes the first and second fixed ends to move outward relative to each other, flattening the carpet pressed against the first and second fixed ends. This utility model, by setting up a drive mechanism, uses a motor-driven cam to drive the second hammer plate to reciprocate and strike the first hammer plate, achieving automatic flattening of the carpet edge. This process eliminates the need for manual knee-bumping of the carpet support, significantly reducing operational difficulty and reliance on worker skill, while also avoiding knee injuries caused by manual impact.

Technical Field

[0001] This utility model relates to the field of carpet laying technology, and in particular to a carpet edge-pulling and wrinkle-preventing device. Background Technology

[0002] During carpet installation, wrinkles and unevenness often occur at the edges. Traditional solutions typically rely on manually striking the carpet stretcher with one's knee to straighten it. This involves placing the fixed end of the stretcher (which has teeth at the bottom) onto the carpet, and the other end having an impact point. After placement, the worker uses their knee to strike the impact point, thus straightening the carpet. This process is undoubtedly difficult, requires a high level of worker skill, and is prone to knee injuries, posing safety concerns. Therefore, a carpet edge-pulling and wrinkle-preventing device is proposed to address these issues. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-5 This utility model provides a carpet edge-pulling and wrinkle-preventing device, comprising a first fixed end 1 and a second fixed end 2. A fixed beam 3 is fixedly connected to the first fixed end 1, and a fixed box 4 that slides with the fixed beam 3 is fixedly connected to the second fixed end 2. It also includes a drive mechanism, which is disposed inside the second fixed end 2. The drive mechanism includes a motor part 23 and a second hammer plate 15. The motor part 23 is prior art and includes a motor and speed control modules, which will not be described in detail. When the motor part 23 works, it drives the second hammer plate 15 to move back and forth, so that the second hammer plate 15 repeatedly hammers the first hammer plate 13 at the inner end of the fixed beam 3, so that the first fixed end 1 and the second fixed end 2 move outward relative to each other, and flatten the carpet pressed on the first fixed end 1 and the second fixed end 2.

[0022] The drive mechanism also includes a second fixed ring 8 fixedly connected to the fixed box 4. A pair of first slide rods 9 and a pair of second slide rods 10 are fixedly connected to both ends of the second fixed ring 8. The first hammer plate 13 is slidably connected to the pair of first slide rods 9. A cam 21 is fixedly connected to the output end of the motor part 23. A cam groove 22 is provided on the cam 21. A first fixed ring 17 is slidably connected to the pair of second slide rods 10. A protrusion 20 that slides with the cam groove 22 is fixedly connected to the first fixed ring 17. A support rod 16 is fixedly connected between the first fixed ring 17 and the second hammer plate 15. A second sliding hole 19 and a pair of first sliding holes 18 are provided on the first fixed ring 17. The pair of first sliding holes 18 and the pair of second slide rods 10 are slidably connected. The cam 21 moves within the second sliding hole 19, and the second sliding hole 19 does not contact the cam 21.

[0023] When the motor 23 is powered on, its output drives the cam 21 to rotate. As the core transmission component, the cam 21 has a cam groove 22 that precisely engages with the protrusion 20 on the first fixed ring 17. As the cam continues to rotate, the cam groove pushes the protrusion to slide back and forth along the second sliding hole 19, thereby driving the first fixed ring 17 to perform linear reciprocating motion on the second slide rod 10. The first fixed ring 17 is fixedly connected to the second hammer plate 15 via the support rod 16, and its reciprocating motion is directly converted into the linear hammering action of the second hammer plate. During the reciprocating movement, the end of the second hammer plate precisely aligns with and repeatedly hammers the first hammer plate 13 at the inner end of the fixed beam 3. The hammering force is transmitted through the first hammer plate to the entire fixed beam, thereby causing the first fixed end 1 and the second fixed end 2 to move slowly and steadily outward relative to each other.

[0024] A buffer pad 14 is fixedly connected to one end of the first hammer plate 13. The end of the second hammer plate 15 away from the support rod 16 faces the first hammer plate 13. A pair of first sliding rods 9 pass through the buffer pad 14, and the first fixing ring 17 and the buffer pad 14 are in contact. A first spring 11 and a second spring 12 are respectively sleeved on the pair of first sliding rods 9 and the pair of second sliding rods 10. The pair of first springs 11 are located between the first hammer plate 13 and the inner wall of the fixing box 4, and the pair of second springs 12 are located between the first fixing ring 17 and the inner wall of the fixing box 4.

[0025] The first spring 11 and the second spring 12 play crucial roles throughout the entire operation. The first spring is mounted on the first slide rod 9, located between the first hammer plate 13 and the inner wall of the fixed box 4. After each hammer blow, the first spring quickly rebounds, pulling the first hammer plate back to its initial position, preparing for the next blow. The second spring is sleeved on the second slide rod 10, located between the first fixed ring 17 and the inner wall of the fixed box 4. When the first fixed ring is pushed by the rotation of the cam, the second spring plays a certain role in shock absorption, reducing the impact between the cam and the cam rod, ensuring the smooth operation of the entire drive mechanism. When the motor stops working, the second spring also participates in pulling the first fixed ring back to its initial position, restoring the entire device to its initial state.

[0026] The top wall of the fixing box 4 is equipped with a removable cover plate 6, and a handle 7 is fixedly connected to the cover plate 6. The bottom wall of the fixing box 4 is fixedly connected with a roller 5. During the carpet laying process, the operator can easily push the device to move along the edge of the carpet to adapt to the flattening needs of different positions.

[0027] Working principle: When in use, first place the first fixed end 1 and the second fixed end 2 in a suitable position on the carpet. When the motor part 23 is started, the motor drives the cam 21 to rotate. Due to the cooperation between the cam groove 22 and the convex rod 20, the first fixed ring 17 is pushed to move back and forth along the second slide rod 10. During this process, the first fixed ring 17 drives the second hammer plate 15 to move back and forth through the support rod 16. Each time it moves, the second hammer plate strikes the first hammer plate 13. The hammering force is transmitted to the fixed beam 3 through the first hammer plate 13, causing the first fixed end 1 and the second fixed end 2 to gradually move outward, and the edge of the carpet is evenly flattened.

[0028] During operation, the cushioning pad 14 absorbs part of the impact force with each hammer blow, protecting the carpet surface, reducing wear on internal components of the device, and lowering hammering noise.

[0029] The first spring 11 and the second spring 12 play the role of storing force and resetting during the hammering process. It should be noted that the elasticity of the second spring 12 is greater than that of the first spring 11.

[0030] 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.
