[0027] This application provides a double-grooving tool for masonry.

[0028] like Figure 1 and Figure 2 As shown, a masonry double grooving tool includes two spaced-apart fixed rods 1. One end of the two fixed rods 1 on the same side is connected by a first connecting rod 2, and the other ends of the two fixed rods 1 are connected by a second connecting rod 3. The fixed rod 1 is provided with a grooving knife 4 at the end near the first connecting rod 2. Both ends of the first connecting rod 2 are provided with baffles 5, and the two fixed rods 1 are located between the two baffles 5.

[0029] The spacing between the two slots is consistent with the spacing between the two slots on the masonry 7. The baffle 5 is used to abut against the opposite sides of the masonry 7. The slotting knife 4 is used to slot the top surface of the masonry 7. The first connecting rod 2 and the second connecting rod 3 are used for the operator to hold. When the two baffles 5 abut against the opposite sides of the masonry 7, the slotting knife 4 is aligned with the preset slotting position on the masonry 7. During the slotting process, the tool of this application is placed on the masonry 7, so that the two baffles 5 abut against the sides of the masonry 7, and the two baffles 5 clamp the masonry 7 in the middle. Due to the restriction of the baffles 5, the two slotting knives 4 are aligned with the preset slotting position. Then, the operator holds the first connecting rod 2 and the second connecting rod 3 and applies pressure to the first connecting rod 2, so that the slotting knife 4 abuts against the top surface of the masonry 7. The pressure is maintained and the first connecting rod 2 and the second connecting rod 3 are pulled to move the slotting knife from one end of the masonry 7 to the other end, forming a slot at the position where the slotting knife 4 passes. During the movement of the grooving cutter 4, the two baffles 5 always abut against the sides of the masonry 7, forming a limiting effect to ensure that the grooving cutter 4 is always aligned with the preset grooving position, and simultaneously forms two grooves, ensuring the spacing between the grooves and the straightness of each groove.

[0030] In this embodiment, the first connecting rod 2 and the fixing rod 1 are connected together by welding, and the second connecting rod 3 and the fixing rod 1 are connected together by welding.

[0031] The grooving cutter 4 includes a blade 41 and a plurality of serrated cutting edges 42. The blade 41 is fixedly connected to a fixing rod 1. The serrated cutting edges 42 are disposed on one side of the blade 41, and the plurality of serrated cutting edges 42 are distributed sequentially along the length of the fixing rod 1. During the pulling of the grooving cutter 4, the plurality of serrated cutting edges 42 sequentially cut the grooving position to form a groove. In this embodiment, the blade 41 and the serrated cutting edges 42 are integrally formed.

[0032] The serrated blade 42 is bent from the root of the blade body 41 to the tip of the blade body 41, with the tip of the serrated blade 42 bent toward the side of the second connecting rod 3. During the grooving process, the operator pulls the grooving tool and gradually pulls it back, moving the grooving knife 4 from one end of the masonry 7 to the other. From the operator's perspective, the first connecting rod 2 is in front and the second connecting rod 3 is behind; from the tool's direction of movement, the first connecting rod 2 is behind and the second connecting rod 3 is in front. In this application, the tip of the serrated blade 42 is bent toward the side of the masonry 7 that has not yet been grooved, facilitating the breaking of the surface of the masonry 7 by the tip of the serrated blade 42 during the pulling of the grooving knife 4, thus improving grooving efficiency.

[0033] Along the length of the fixed rod 1, the thickness of the first serrated blade 42 closest to the second connecting rod 3 is less than the preset width of the groove on the masonry 7, and the thickness of the last serrated blade 42 furthest from the second connecting rod 3 is greater than or equal to the preset width of the groove on the masonry 7. The serrated blades 42 near the ungrooved portion of the masonry 7 are thinner, increasing the pressure of the serrated blades 42 on the masonry 7, making it easier for the grooving knife 4 to break through the masonry 7 and improving the grooving efficiency. The serrated blades 42 on the rear side are consistent with the preset width of the groove on the masonry 7, and the last serrated blade 42 widens the narrower groove, ensuring that the groove width meets the standard.

[0034] The thickness of the plurality of serrated cutting edges 42 between the first and last serrated cutting edges 42 increases along the direction from the second connecting rod 3 to the first connecting rod 2. Based on the direction of tool movement, the thickness of the serrated cutting edges 42 gradually increases from front to back, so that the plurality of serrated cutting edges 42 located behind the first serrated cutting edge 42 gradually widen the groove, reducing the risk of the last serrated cutting edge 42 getting stuck when widening the groove.

[0035] like Figure 3 and Figure 4 As shown, a limiting cover 6 is provided on the fixed rod 1 or the first connecting rod 2. The limiting cover 6 includes a part of the grooving knife 4. The bottom of the limiting cover 6 is provided with a through groove 61 for the blade of the grooving knife 4 to extend out, and the height of the grooving knife 4 extending out of the bottom surface of the limiting cover 6 is equal to the preset depth of the grooving on the masonry 7.

[0036] In this embodiment, the design of the limiting cover 6 allows the grooving knife 4 to extend a fixed length of blade, avoiding the problem of excessive grooving caused by excessive force applied by the operator, and ensuring the uniformity and quality of grooving.

[0037] The limiting cover 6 includes side plates 62 and a bottom plate 63. The bottom plate 63 is connected to the same side of the two side plates 62. The side plates 62 are mounted on the fixed rod 1 or the first connecting rod 2. A ball bearing is provided on the bottom surface of the bottom plate 63. The through groove 61 is provided on the bottom plate 63. The bottom surface of the ball bearing serves as the bottom surface of the limiting cover 6. The extension length of the grooving cutter 4 is calculated from the bottom plane of the ball bearing. In this application, the ball bearing contacts the masonry surface, which can reduce the scraping of the limiting cover 6 on the masonry 7 and reduce the resistance during the movement of the tool. The ball bearing is not shown in the attached drawings.

[0038] Mounting lugs 65 are fixed on the opposite sides of the side plates 62 on both sides. Mounting plate 11 is provided on the fixing rod 1 or the first connecting rod 2. Mounting lugs 65 and mounting plate 11 are fixedly connected by bolts 67. A number of rigid washers 66 are provided between mounting lugs 65 and mounting plate 11 and are sleeved on the outer periphery of bolts 67.

[0039] In this embodiment, the top of the fixing plate is higher than the first connecting rod 2, the mounting plate 11 is fixed to the top of the fixing rod 1, and the side plates 62 are located on both sides of the grooving knife 4. The fixing is changed to be between the two side plates 62. The side plates 62 are provided with a relief groove 68 that avoids the first connecting rod 2. Each side plate 62 is provided with two spaced mounting lugs 65. The space between the two mounting lugs 65 on each side plate 62 is aligned with the relief groove 68 so that the first connecting rod 2 can pass through before the limiting cover 6 is sleeved on the outer periphery of the grooving head to connect the mounting plate 11 and the mounting lugs 65. In this embodiment, each mounting lug 65 and the mounting plate 11 are provided with a number of rigid shims 66 sleeved on the outer periphery of the bolt 67. By adjusting the number of rigid shims 66, the length of the grooving knife 4 extending out of the limiting cover 6 is adjusted, and the maximum grooving depth of the grooving knife 4 is controlled to meet different grooving requirements. The side plate 62, the bottom plate 63 and the mounting lug 65 are integrally formed. After the mounting lug 65 is connected, the first connecting rod 2 is located between the bottom plate 63 and the mounting plate 11.

[0040] In other embodiments, the sides of the two side plates 62 can also be connected by a connecting plate 64, so that the connecting plate 64 connects the side plates 62 and the bottom plate 63 at the same time, thereby strengthening the overall strength of the limiting cover 6. Meanwhile, the connecting plate 64 is provided with a hollow groove 69 to avoid the fixing rod 1.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
