Description

Technical Field

[0001] This utility model relates to the field of cemented carbide blade technology, specifically to a cemented carbide blade that prevents loosening. Background Technology

[0002] Carbide inserts are made of carbide, an alloy material produced by powder metallurgy from hard compounds of refractory metals and binder metals. It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance.

[0003] In response, the existing technology patent publication number CN222660159U discloses a carbide blade with anti-loosening capability, belonging to the field of carbide blade technology. The blade has multiple mounting holes, openings on both sides, and anti-loosening plates in two of the openings. Threaded holes are also present on both sides of the blade, with bolts installed in both threaded holes. A sliding groove is formed in each of the two openings, and a top bar is installed in each of the two sliding grooves. Both top bars are movably connected to the bolts.

[0004] However, in actual use, when installing the blade, the anti-detachment plate can only be moved by the spring force, resulting in poor overall anti-detachment effect. Furthermore, if there is a gap between the blade and the mounting frame, it may fall off. Therefore, improving and perfecting these issues is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a carbide blade that prevents loosening, in order to solve the problems mentioned in the background art, where the anti-loosening plate can only be moved by the elastic force of the spring during the overall use, resulting in poor overall anti-loosening effect, and the blade will also fall off if there is a gap between it and the mounting frame during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbide knife with anti-loosening features, including a mounting frame, an mounting block installed inside the mounting frame, a blade body installed on the right side of the mounting block, an anti-loosening component installed on the outer surface of the mounting block, and a locking component installed inside the mounting block. The anti-detachment component includes a fastening plate, which is installed on the left side surface of the mounting block. The front and rear surfaces of the mounting block are provided with operating grooves, and auxiliary bolts are installed inside the operating grooves. A first limiting hole is inserted into the fastening plate, and a pushing column is installed inside the first limiting hole.

[0007] Preferably, the front and rear surfaces of the mounting frame are equipped with side blocks, and the interior of the side blocks has grooves that are compatible with the operating groove.

[0008] Preferably, a stabilizing plate is fixedly connected to the left side surface of the pushing column, and an abutting plate is fixedly connected to the left side of the stabilizing plate.

[0009] Preferably, the auxiliary bolt is threadedly installed between itself and the operating groove, and the outer surface of the auxiliary bolt abuts against the right side surface of the push column.

[0010] Preferably, the fastening plate has a second limiting hole inside, and there are two sets of the second limiting hole, which have the same structure as the first limiting hole.

[0011] Preferably, the locking assembly includes a locking groove, which is formed on the upper surface of the mounting block and the mounting frame. A locking block is installed inside the locking groove, and the lower end of the locking block is provided with a locking groove. The locking groove is inverted trapezoidal, and the top surface of the locking block is provided with a threaded hole.

[0012] Preferably, the side block has an adapter groove inside, and a fitting block is installed inside the adapter groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This anti-loosening carbide blade, through the anti-loosening component, not only secures the mounting block to the mounting frame, but also, after the overall installation is completed, drives the contact plate and stabilizing plate to stably abut against the inner wall of the mounting frame, ensuring a stable connection between the mounting frame and the mounting block, and providing a good overall anti-loosening effect.

[0014] 2. This anti-loosening carbide blade, through the locking component, not only locks the middle position of the mounting block to the mounting frame, but also enhances the contact stability between the mounting frame and the mounting block, ensuring that it will not loosen later, and also has a tight fit when installing the side block.

[0017] 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.

[0018] Please see Figures 1-5 One embodiment provided by this utility model: A carbide knife with anti-loosening mechanism. The blade body 3, auxiliary bolt 6 and trapezoidal block 15 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. It includes a mounting frame 1, a mounting block 2 installed inside the mounting frame 1, a blade body 3 installed on the right side of the mounting block 2, an anti-loosening component installed on the outer surface of the mounting block 2, and a locking component installed inside the mounting block 2. The anti-detachment component includes a fastening plate 4, which is installed on the left side surface of the mounting block 2. The mounting block 2 has operating grooves 5 on both its front and rear surfaces. An auxiliary bolt 6 is installed inside the operating groove 5. A first limiting hole 8 is inserted inside the fastening plate 4, and a pushing column 9 is installed inside the first limiting hole 8. Side blocks 7 are installed on the front and rear surfaces of the mounting frame 1. The side blocks 7 have grooves inside that are compatible with the operating grooves 5. A stabilizing plate 10 is fixedly connected to the left side surface of the pushing column 9, and an abutment plate 11 is fixedly connected to the left side of the stabilizing plate 10. The auxiliary bolt 6 is threaded into the operating groove 5, and its outer surface abuts against the right side surface of the pushing column 9. At this point, the mounting block 2 is installed into the interior of the mounting frame 1. Then, the auxiliary bolt 6 is aligned with the grooves inside the operating slot 5 and the side block 7, allowing the auxiliary bolt 6 to be tightened inside the operating slot 5. This locks the mounting block 2 to the mounting frame 1. Simultaneously, the auxiliary bolt 6, when rotating, abuts against the right side surface of the push column 9, causing the push column 9 to move to the left. The push column 9 then drives the stabilizing plate 10 and the contact plate 11 to move to the left. The contact plate 11 then abuts against the inner wall of the mounting frame 1, ensuring stable contact between the mounting block 2 and the inner wall of the mounting frame 1. This enhances stability during contact and prevents loosening between the mounting frame 1 and the mounting block 2. Therefore, this setup, through the anti-detachment component, not only securely installs the mounting block 2 to the mounting frame 1, but also, after overall installation, allows the contact plate 11 and the stabilizing plate 10 to stably abut against the inner wall of the mounting frame 1, ensuring a stable connection between the mounting frame 1 and the mounting block 2. The overall anti-detachment effect is good.

[0019] The fastening plate 4 has a second limiting hole 12 inside. There are two sets of the second limiting hole 12, and the structure is the same as that of the first limiting hole 8. At this time, the first limiting hole 8 and the second limiting hole 12 are both equipped with a pushing post 9. So when the locking block 14 and the trapezoidal block 15 move downward, the trapezoidal block 15 first abuts against the right side of the pushing post 9, and then continues to abut against the locking block 14 to fix the position of the pushing post 9.

[0020] The locking assembly includes a locking groove 13, which is formed on the upper surface of the mounting block 2 and the mounting frame 1. A locking block 14 is installed inside the locking groove 13, and the lower end of the locking block 14 has the locking groove 13. The locking groove 13 is inverted trapezoidal, and a threaded hole is formed on the top surface of the locking block 14. An adapter groove 16 is formed inside the side block 7, and a fitting block 17 is installed inside the adapter groove 16. After the mounting frame 1 and mounting block 2 are stably installed, the locking block 14 is installed inside the locking groove 13. The trapezoidal block 15 below the locking block 14 is an inverted trapezoid. The trapezoidal block 15 and the locking block 14 can slowly push the right side of the pushing column 9 against each other, thereby driving the abutment plate 11 to move to the left. At this time, the mounting frame 1 and the mounting block 2 are in contact with each other through the abutment plate 11 and the stabilizing plate 10, thus directly avoiding the phenomenon of gaps. When the locking block 14 needs to be removed later, the screw is aligned with the threaded hole on the top surface of the locking block 14, and then the screw is locked with the locking block 14 before the locking block 14 is pulled out. The locking block 14 and the locking groove 13 are connected by a tenon and mortise joint, and the overall installation also has a locking effect.

[0021] At this time, the mounting block 2 is installed inside the mounting frame 1. The side block 7 is equipped with a fitting block 17, which makes the fitting between the mounting frame 1 and the mounting block 2 more stable. Therefore, this setting can not only lock the middle position of the mounting block 2 to the mounting frame 1 through the locking component, but also strengthen the contact stability between the mounting frame 1 and the mounting block 2, ensuring that there will be no loosening later, and also has a tight fitting effect when the side block 7 is installed.

[0022] Working principle: In use, the mounting block 2 is installed into the mounting frame 1. Then, the auxiliary bolt 6 is aligned with the grooves inside the operating slot 5 and the side block 7. The auxiliary bolt 6 can be screwed into the operating slot 5 to lock the mounting block 2 and the mounting frame 1. At the same time, when the auxiliary bolt 6 rotates, it will abut against the right side surface of the push column 9, which will move the push column 9 to the left. The push column 9 will then drive the stabilizing plate 10 and the abutting plate 11 to move to the left. At this time, the abutting plate 11 can abut against the inner wall of the mounting frame 1, so that the mounting block 2 and the inner wall of the mounting frame 1 are stably abutted, which enhances the stability of the abutment and ensures that there is no loosening between the mounting frame 1 and the mounting block 2. After the mounting frame 1 and mounting block 2 are stably installed, the locking block 14 is installed inside the locking groove 13. The trapezoidal block 15 below the locking block 14 is an inverted trapezoid. The trapezoidal block 15 and the locking block 14 can slowly push the right side of the pushing column 9 against each other, thereby driving the contact plate 11 to move to the left. At this time, the mounting frame 1 and the mounting block 2 are in contact with each other through the contact plate 11 and the stabilizing plate 10, thus directly avoiding the phenomenon of gaps. When the locking block 14 needs to be removed later, the screw is aligned with the threaded hole on the top surface of the locking block 14, and then the screw is locked with the locking block 14 before the locking block 14 is pulled out. The locking block 14 and the locking groove 13 are connected by a tenon and mortise, and the overall installation also has a locking effect. At this time, the mounting block 2 is installed inside the mounting frame 1. The side block 7 is provided with a fitting block 17, which makes the fitting between the mounting frame 1 and the mounting block 2 more stable. The above is the working principle of this utility model.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
