Description

Technical Field

[0001] The utility model relates to the field of hook knife equipment, in particular to tungsten steel coated hook knife particles. Background Art

[0002] Coating the hook knife with tungsten steel coating can increase the hardness, wear resistance, strength and toughness of the hook knife. Therefore, the tungsten steel coating is combined with the hook knife to increase the service life of the hook knife. The existing hook knife is usually fixed and squeezed on the equipment when in use. The friction between the equipment and the hook knife cannot be increased through a single opening, and the hook knife is easy to slide on the equipment.

[0003] According to a tungsten steel coating forming hook knife disclosed in the existing patent document with announcement number CN217912897U, it includes a handle, a disassembly and assembly mechanism is arranged on the lower side of the handle, including a mounting box, a limit frame, an adjustment rod and a fixing frame; a cutter head, a connecting mechanism is arranged above the cutter head, and the cutter head is installed with the handle through the connecting mechanism, including a limit block, a mounting block and a connecting block, and the front end of the cutter head is tightly fitted with a workpiece; the handle and the cutter head are both made of wear-resistant ultrafine particle cemented carbide, and the outer side is sprayed with Balzers high-hardness nano coating. When in use, this technical solution forms the required contour shape of the workpiece through the machining center, and is designed as a single blade, which can avoid the workpiece. The workpiece processed by the hook knife has no knife marks, no different colors, and low surface roughness. With respect to the above technical solution, although this solution achieves low surface roughness of the hook knife, it is impossible to cover the position of the blade when not in use, which is easy to cause harm to the user and inconvenience when in use. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a tungsten steel coated hook knife blade to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. When in use, the movable frame is movably installed inside the slot from one end of the slot opening through a protrusion, and one end of the movable frame contacts the inner wall of the connecting piece. The position of the blade is shielded by the movable frame, thereby avoiding the danger caused by the blade when not in use.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a tungsten steel coated hook knife pellet, comprising a hook knife pellet body, the hook knife pellet body comprising a fixed seat, both ends of the fixed seat are fixedly connected with connecting plates, one side of the connecting plate is provided with a blade, the fixed seat is provided with an opening, a protrusion is fixed on the inner wall of the opening, and a groove is provided between the fixed seat and the connecting plate.

[0006] Furthermore, one end of the slot is provided with an opening, and a movable frame is movably mounted on the fixing seat.

[0007] Furthermore, a sliding block is fixed on the inner wall of the movable frame, and the sliding block is movably installed inside the slot through the opening.

[0008] Furthermore, the fixing seat, the connecting piece and the protrusion are all coated with a tungsten steel coating.

[0009] Furthermore, the connecting pieces are symmetrically mounted at both ends of the fixing base.

[0010] Furthermore, one end of the movable frame is movable to contact one side of the connecting piece.

[0011] The beneficial effects of the utility model are as follows: the tungsten steel coated hook knife blade of the utility model comprises a fixing seat, an opening, a convex block, a slot, a movable frame, a connecting piece, a blade and a sliding block.

[0012] 1. The tungsten steel coated hook knife blade has a movable frame that is movably installed inside the slot from one end of the slot opening through a slider when in use. One end of the movable frame contacts the inner wall of the connecting piece, and the position of the blade is shielded by the movable frame, thereby avoiding the danger caused by the blade when not in use.

[0013] 2. The tungsten steel coated hook knife blade is taken out of the slotted inner part when in use. After being taken out, the slot can cool down the whole equipment to avoid damage caused by high temperature of the blade. In addition, a convex block is fixed on the inner wall of the opening. The convex block cooperates with the mounting structure to increase the contact friction with the fixed seat, and the fixed seat is limited and fixed as a whole to avoid shaking of the fixed seat on the fixed structure in the later stage.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 and Figure 2The utility model provides a technical solution: a tungsten steel coated hook knife pellet, comprising a hook knife pellet body, the hook knife pellet body comprising a fixed seat 1, two ends of the fixed seat 1 are fixedly connected with connecting pieces 6, one side of the connecting piece 6 is provided with a blade 7, an opening 2 is provided on the fixed seat 1, a protrusion 3 is fixed on the inner wall of the opening 2, a slot 4 is provided between the fixed seat 1 and the connecting piece 6, one end of the slot 4 is provided with an opening, a movable frame 5 is movably installed on the fixed seat 1, the movable frame 5 is movably installed inside the slot 4 from one end of the slot 4 opening through a slider 8, one end of the movable frame 5 is in contact with the inner wall of the connecting piece 6, and the position of the blade 7 is shielded by the movable frame 5.

[0020] In this embodiment, a slider 8 is fixed on the inner wall of the movable frame 5, and the slider 8 is movably installed inside the slot 4 through the opening. The fixed seat 1, the connecting piece 6 and the protrusion 3 are all coated with tungsten steel coating. The connecting piece 6 is symmetrically installed at both ends of the fixed seat 1. One end of the movable frame 5 is movably in contact with one side of the connecting piece 6. The connecting pieces 6 are distributed at both ends of the fixed seat 1. When the connecting piece 6 at one position is damaged, it can be rotated to replace the connecting piece 6 on the other side for continued use.

[0021] When the device is carried and moved, the movable frame 5 is movably installed in the slot 4 from one end of the slot 4 opening through the slider 8, and the movable frame 5 slides in the slot 4, sliding to make one end of the movable frame 5 contact with the inner wall of the connecting piece 6, and the position of the blade 7 is blocked by the movable frame 5, thereby avoiding the danger caused by the blade 7 when not in use. When in use, the movable frame 5 is taken out from the inside of the slot 4 through the slider 8, and the fixed seat 1 is installed in the use position through the opening 2 after being taken out. The protrusion 3 cooperates with the groove at the installation position to increase the support point, thereby providing multi-point support for the fixed seat 1 to avoid loosening caused by the fixed seat 1 at the installation position in the later stage. When in use, one end of the connecting piece 6 enters the cutting position, and the cutting is completed by the blade 7. The connecting pieces 6 are symmetrically distributed at both ends of the fixed seat 1. When the connecting piece 6 at one position is damaged, it can be rotated to replace the connecting piece 6 on the other side and continue to be used. After the movable frame 5 is taken out from the inside of the slot 4, the slot 4 can cool down the equipment as a whole to avoid damage caused by the overall high temperature of the knife particles.
