Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a pusher blade. Background Technology

[0002] Tiles, as a hard material widely used in building decoration, have properties such as wear resistance, water resistance, and easy cleaning. However, their high brittleness and smooth surface also make them difficult to process. In actual decoration scenarios, to adapt to irregular spaces (such as corners, pipe penetrations, and socket grooves) or to achieve personalized designs (such as border lines and geometric splicing), tiles need to be precisely cut, grooved, or have their edges trimmed.

[0003] However, the traditional cutting method usually involves workers manually cutting the tiles with a cutting knife. This method is limited by the precision of human control. During the cutting process, relative displacement can easily occur between the tool and the tile, causing the cutting line to deviate, resulting in single-cut failures. Repeated corrections can also cause damage to the tile edges, increasing material waste and rework costs. Utility Model Content

[0004] Therefore, in order to solve the problem that traditional manual cutting blades are prone to relative displacement between themselves and the tiles during the cutting process, resulting in cutting line deviation and single-cut failure, the purpose of this utility model is to provide a pusher blade, the specific technical solution of which is as follows: A pusher includes a push rod, a pusher structure, and a locking structure. The pusher structure is movably connected to the push rod. The locking structure is fixedly connected to one end of the push rod. The locking structure includes a locking seat, a first sliding part, and a second sliding part. The locking seat is fixedly connected to the push rod. A sliding groove is formed in the locking seat. The first sliding part is disposed in the receiving groove and slidably connected to the locking seat. The second sliding part is rotatably connected to the end of the locking seat away from the pusher structure.

[0005] Compared with existing technologies, this utility model pusher knife has the following advantages: By setting a locking structure, a stable support and positioning foundation is provided for the entire pusher knife during the cutting process, ensuring the accurate execution of the cutting action. The locking structure includes a locking seat, a first sliding part, and a second sliding part. The locking seat is the main frame of the locking structure, integrating the first and second sliding parts into an organic whole, allowing the locking structure to be stably installed on the push rod. The first sliding part ensures the stability of the cutting direction, reduces the possibility of cutting line deviation, and improves cutting accuracy. The second sliding part is used to abut against the side of the tile, cooperating with the first sliding part to form a multi-point support system, further enhancing the stability of the device during the cutting process. This utility model pusher knife, by utilizing the cooperation of the two sliding parts of the locking structure, the stable support of the push rod, and the flexible movement of the pusher structure, effectively improves the cutting accuracy and stability, reduces the relative displacement between the tool and the tile during the cutting process, and improves cutting efficiency and quality.

[0011] In some embodiments, the mounting base includes a first upright block, a mounting block, and a second upright block. The first upright block, the mounting block, and the second upright block are respectively fixedly connected to the movable base. The first upright block and the second upright block are arranged symmetrically about the mounting block. The blade body is detachably connected to the mounting block.

[0012] In some embodiments, the ends of both the first and second upright blocks away from the movable seat can be detachably fitted with protective sleeves.

It should be understood that the specific embodiments described herein are only for explaining this utility model and do not limit the scope of protection of this utility model.

[0018] It should be noted that "greater than", "less than", "exceeding", etc. are understood to exclude the number itself, "several" and "more than" mean one or more, and "above", "below", "within" etc. are understood to include the number itself. If the first or second is mentioned, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0019] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] The following descriptions of directions are defined as follows: The length direction of the card slot is set to the X direction.

[0022] Figures 1-2 The diagram schematically illustrates a pusher according to one embodiment of the present invention, including a push rod 1, a pusher structure 2, and a locking structure 3. The pusher structure 2 is movably connected to the push rod 1, allowing the pusher structure 2 to move flexibly along the push rod 1, facilitating cutting operations at different positions. The locking structure 3 is fixedly connected to one end of the push rod 1, providing stable support and positioning for the entire pusher during the cutting process, ensuring accurate execution of the cutting action.

[0023] like Figures 3-4As shown, the locking structure 3 includes a locking seat 31, a first sliding part 32, and a second sliding part 33. The locking seat 31 is fixedly connected to the push rod 1. The locking seat 31 is the main frame of the locking structure 3, which can integrate the first sliding part 32 and the second sliding part 33 together to form an organic whole, so that the locking structure 3 can be stably installed on the push rod 1. The locking seat 31 has a receiving groove 311, which provides installation space for the first sliding part 32 and provides stable support for the entire pusher during cutting. The first sliding part 32 is disposed within the receiving groove 311 and is slidably connected to the locking seat 31. The first sliding part 32 includes a slide rail 321 and several first pulleys 322. A sliding groove 312 is formed within the receiving groove 311. The slide rail 321 is disposed within the sliding groove 312 and can be slidably connected to the locking seat 31 along its length (X direction). When it is necessary to replace the first sliding part 32 with first pulleys 322 of different specifications, the first sliding part 32 can be directly slid out of the locking seat 31. Each first pulley 322 is rotatably connected to the slide rail 321. During the cutting process, when the pusher moves on the surface of the tile, the first pulleys 322 contact and roll with the surface of the tile, converting sliding friction into rolling friction, which greatly reduces the friction between the pusher and the tile, making the pusher move more easily and smoothly, and improving cutting efficiency. Furthermore, the multiple first pulleys 322 are evenly and equidistantly distributed within the receiving groove 311, which ensures more uniform force distribution on the pusher during movement, preventing tilting or wobbling of the pusher due to excessive local force. This guarantees the stability of the cutting direction, reduces the possibility of cutting line deviation, and improves cutting accuracy. In this embodiment, the second sliding part 33 includes several second pulleys 3311. Each second pulley 331 is rotatably connected to the end of the locking seat 31 away from the pusher structure 2. The second pulleys 331 are used to abut against the side of the tile, cooperating with the first pulleys 322 to form a multi-point support system, further enhancing the stability of the device during the cutting process. The axial direction of each first pulley 322 is perpendicular to the length direction (X direction) of the locking seat 31, ensuring that the rolling direction of the first pulley 322 is consistent with the moving direction (i.e., the cutting direction) of the locking seat 31 when rolling. When the device moves on the tile surface to cut, the first pulleys 322 can roll stably along a straight line, providing precise linear guidance for the entire device. The axial direction of each second pulley 331 is perpendicular to the locking seat 31, further enhancing the linear guiding function. The second pulley 331 and the first pulley 322 form a cooperating guiding system. Through the cooperation of the second pulley 331 and the first pulley 322, the tile is supported and guided, further enhancing the stability during the cutting process, ensuring accurate cutting direction, and reducing the problem of cutting line deviation caused by shaking.

[0024] In this embodiment, a baffle 34 is fixedly connected to the positioning seat 31. The baffle 34 is located at the end of the positioning seat 31 away from the pusher structure 2. The baffle 34 is integrally formed with the positioning seat 31. Each second pulley 331 is located between each first pulley 322 and the baffle 34. The baffle 34 plays a limiting and protective role for the second pulley 331, preventing the second pulley 331 from popping out due to accidental dislocation during movement, thereby maintaining the stability of the entire positioning structure 3.

[0025] like Figure 5 As shown, the push rod 1 includes an outer frame 11 and a reinforcing plate 12. The outer frame 11 is hexagonal, which increases the strength and stability of the push rod 1, making it less prone to deformation when subjected to forces such as the movement of the pusher structure 2. Two reinforcing plates 12 are provided, symmetrically arranged inside the outer frame 11, further enhancing the compressive strength of the push rod 1 and ensuring that the push rod 1 will not be damaged due to force during long-term use. In this embodiment, a groove 111 is provided on the side of the outer frame 11 near the mounting base 31. The groove 111 provides a relatively independent sliding space for the pusher structure 2, reducing the contact area between the pusher structure 2 and the push rod 1, thereby reducing friction and making it easier and smoother for the pusher structure 2 to move on the push rod 1, improving the flexibility and efficiency of the cutting operation. In addition, in other embodiments, a scale can be added inside the groove 111 for auxiliary measurement of dimensions. One end of the push rod 1 is vertically fixed to the middle of the locking seat 31, ensuring the stability of the angle between the locking seat 31 and the push rod 1. This allows the locking structure 3 to accurately perform its supporting and guiding functions, ensuring the overall stability of the pusher during the cutting process and facilitating high-precision cutting. In this embodiment, one end of the push rod 1 is fixedly connected to the locking seat 31 by bolts.

[0026] like Figure 2 , Figure 6 As shown, the pusher structure 2 includes a movable seat 21, a mounting seat 22, and a blade body 23. The movable seat 21 and the mounting seat 22 are fixedly connected. A movable hole 211 is provided in the middle of the movable seat 21. The push rod 1 passes through the movable hole 211 and is movably connected to the movable seat 21, allowing the pusher structure 2 to move freely on the push rod 1. The blade body 23 is detachably connected to the mounting seat 22, making it convenient to replace the blade body 23 according to different cutting needs. The cutting surface of the blade body 23 is at the same height as the sliding surface of the first pulley 322, ensuring accurate contact angle between the blade body 23 and the tile surface during cutting, uniform cutting force, and improved cutting quality.

[0027] The mounting base 22 includes a first upright block 221, a mounting block 222, and a second upright block 223. The first upright block 221, mounting block 222, and second upright block 223 are fixedly connected to the movable base 21. The first upright block 221 and second upright block 223 are symmetrically arranged about the mounting block 222. The blade body 23 is detachably connected to the mounting block 222. The symmetrical arrangement of the first upright block 221 and second upright block 223 enhances the strength and stability of the mounting base 22, ensuring that the blade body 23 will not wobble during cutting, thus guaranteeing the straightness and accuracy of the cut. In this embodiment, a protective sleeve 224 is detachably provided at the end of the first upright block 221 and second upright block 223 away from the movable base 21. The protective sleeve 224 covers the bottom of the first upright block 221 and second upright block 223, effectively preventing damage to the tile caused by contact or collision during cutting.

[0028] A locking element 24 is provided on the movable seat 21. The function of the locking element 24 is to fix the movable seat 21 at a specific position on the push rod 1 during the cutting process, preventing the movable seat 21 from moving freely on the push rod 1 and ensuring the stability of the cutting. The locking element 24 includes an adjusting element 241 and a push rod 242. The adjusting element 241 is fixedly connected to the push rod 242. The end of the push rod 242 away from the adjusting element 241 passes through the movable seat 21 and abuts against the push rod 1. The abutting force between the push rod 242 and the push rod 1 can be easily controlled by the adjusting element 241, realizing the flexible fixing and loosening of the movable seat 21. The operation is simple and convenient. In this embodiment, the push rod 242 is threadedly connected to the movable seat 21. By rotating the adjusting element 241, the push rod 242 is moved, realizing the flexible fixing and loosening of the movable seat 21.

[0029] like Figure 2 , Figure 6 As shown, a distance scale 13 is provided above the push rod 1 to facilitate users to accurately control the cutting length. A reading hole 212 is provided above the movable seat 21, and a reading element 213 is provided inside the reading hole 212. Users can accurately read the cutting distance value through the reading element 213, which improves the cutting accuracy and controllability and avoids material waste and rework problems caused by inaccurate cutting length.

[0030] like Figure 6 As shown, the reading device 213 includes two pointers 2131 symmetrically arranged with respect to the axis of the push rod 1. The two pointers 2131 can clearly display the cutting distance value. Even under different viewing angles (such as left or right operation), at least one pointer is in a clearly visible position, avoiding reading errors caused by the viewing angle deviation of a single pointer.

[0031] like Figure 7As shown, in the operation of this embodiment, the pusher first connects the locking seat 31 and the push rod 1 with bolts to ensure that the push rod 1 and the locking seat 31 are perpendicular to each other. The first pulley 322 is placed above the edge of the tile to be cut, while the second pulley 331 is placed against the side of the edge of the tile. Then, the push rod 1 is moved according to actual needs. The distance scale 13 on the push rod 1 is accurately positioned by the reading device 213 and the distance scale 13 on the push rod 1, and then fixed by the locking device 24, thus completing the preparation work. When cutting begins, the user holds the locking seat 31 and slides it along the cutting direction to cut and mark the tile. After the marking is completed, the tile is divided by the matching auxiliary device.

[0032] The pusher blade in the above embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In the above embodiment, the pusher blade utilizes the cooperation of the two sliding parts of the locking structure 3, the stable support of the push rod 1, and the flexible movement of the pusher blade structure 2 to effectively improve the cutting accuracy and stability, reduce the relative displacement between the tool and the tile during the cutting process, and improve the cutting efficiency and quality.
