Description

Technical Field

[0001] The utility model relates to the technical field of ship rust removal, and particularly relates to a rust removal knife. Background Technique

[0002] Ships work in the seawater erosion and marine atmospheric environment for a long time. Affected by complex factors such as high salinity, high conductivity, and high pH value, key parts such as the hull, deck, and ship bottom of the ship are prone to rust. This kind of rust will not only affect the normal operation of the ship, but also may cause environmental pollution and economic losses. In severe cases, it may even induce marine accidents and endanger life safety.

[0003] At present, in the prior art, when only using a rust removal knife for rust removal, it is necessary to manually scrape and clean the rust repeatedly, which is not only time-consuming and laborious, but also the rust removal efficiency is relatively low. Especially when facing large-area or deep rust, it is difficult to quickly and effectively remove the rust simply by relying on the rust removal knife. In view of this, we propose a rust removal knife. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a rust removal knife, which can solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the rust removal knife proposed by the utility model includes a handle. An opening is provided on the surface of the handle, and a knife body is fixedly connected in the opening. A rust removal component is arranged inside the handle, and a limiting component is arranged on the rust removal component. The rust removal component includes:

[0006] A pressing plate is arranged outside the handle, and liquid outlet holes are provided on the surface of the pressing plate. The liquid outlet holes are communicated with a liquid storage cavity inside the pressing plate;

[0007] A connecting rod is fixedly connected to the outer wall of the pressing plate, and a limiting block is fixedly connected to the inner wall of the connecting rod. There are two groups of limiting blocks, and a sphere one is arranged between the two groups of limiting blocks;

[0008] A piston tube is fixedly connected to the connecting rod. The piston tube is slidably connected in a support seat and a connecting pipe. The support seat is fixedly connected inside the handle;

[0009] A compression spring elastically connects the piston tube and the connecting pipe. The compression spring is limited on the inclined surface of the connecting pipe, and a sphere two is arranged between the inclined surfaces. The connecting pipe is communicated with a liquid collecting box.

[0010] Preferably, the limiting component includes an inclined groove, and the inclined groove is provided on the surface of the pressing plate.

[0011] Preferably, a round block is slidably connected in the inclined groove, and a sliding groove is formed on the surface of the round block. The round block is driven to slide or abut against the limit in the inclined groove by the movement of the sliding groove.

[0012] Preferably, a clamping block is slidably connected in the sliding groove, and the clamping block clamps a rotating rod. When the rotating rod drives the round block to slide to the lowest point of the inclined groove, the clamping block also moves to the lowest point of the sliding groove of the round block. At this time, the round block contacts the inclined groove and generates resistance, thereby restricting the further movement of the round block.

[0013] Preferably, one end of the rotating rod is clamped with the clamping block, and the other end of the rotating rod is rotatably connected to the pressing plate.

[0014] Preferably, a handle is fixedly connected to the surface of the rotating rod, and the rotation of the rotating rod is driven by controlling the handle

[0015] to drive the rotation of the rotating rod.

[0016] The utility model provides a rust-removing knife, which has the following beneficial effects:

[0017] (1) Through the rust-removing component provided by the rust-removing knife, when pressure is applied to the pressing plate, the compression spring will be compressed. The sphere II prevents the liquid in the connecting pipe from flushing upward, the piston pipe pushes the liquid outwards, the sphere I is lifted, and the rust-removing liquid flows out from the liquid collecting box. When the hand is released, the compression spring releases, the piston pipe moves upward, a low-pressure area is generated in the piston pipe and the connecting pipe, so that the rust-removing liquid flushes upward, the rust-removing liquid flows into the low-pressure area, the sphere I is stuck in the limiting block to the left to prevent air from entering, and when the sphere I is pressed again, it is lifted, and the rust-removing liquid flows into the solution cavity and is pushed towards the liquid outlet hole, improving the rust-removing efficiency and the rust-removing effect.

[0018] (2) Through the limiting component provided by the rust-removing knife, by controlling the rotation of the rotating rod driven by the handle, when the rotating rod drives the round block to slide to the lowest point of the inclined groove, the clamping block also moves to the lowest point of the sliding groove of the round block. At this time, the round block contacts the inclined groove and generates resistance, thereby restricting the further movement of the round block, limiting the rust-removing component to prevent liquid leakage, and improving the use effect of the subsequent rust-removing knife.

[0029] The realization, functional features and advantages of the purpose of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figure 1 - Figure 7, the present utility model proposes a rust-removing knife, which includes a handle 1. An opening 101 is provided on the surface of the handle 1, and a knife body 2 is fixedly connected in the opening 101. When using the rust-removing knife for rust-removing operations, the user will hold the handle 1, align the blade of the knife body 2 with the rust on the metal surface, and by applying a certain force and angle, the blade will cut into the rust layer and scrape it off. A rust-removing component 3 is arranged inside the handle 1, and a limiting component 4 is arranged on the rust-removing component 3. The rust-removing component 3 includes a pressing plate 31.

[0032] In an embodiment of the present utility model, in order to improve the rust-removing efficiency and the rust-removing effect, specifically, a pressing plate 31 is arranged outside the handle 1, and liquid outlet holes 32 are provided on the surface of the pressing plate 31. The liquid outlet holes 32 communicate with a liquid storage cavity 301 inside the pressing plate 31. When it is necessary to eject the rust-removing liquid, the user will press the pressing plate 31. As the internal pressure increases, the rust-removing liquid in the liquid storage cavity 301 is pushed towards the liquid outlet holes 32. A connecting rod 33 is fixedly connected to the outer wall of the pressing plate 31, and a limiting block 34 is fixedly connected to the inner wall of the connecting rod 33. There are two groups of limiting blocks 34, and a first sphere 35 is arranged between the two groups of limiting blocks 34. The limiting block 34 limits the leftward movement of the first sphere 35. The connecting rod 33 is fixedly connected to a piston tube 36. The piston tube 36 is slidably connected in a support seat 37 and a connecting pipe 38. The support seat 37 is fixedly connected inside the handle 1. The piston tube 36 and the connecting pipe 38 are elastically connected by a compression spring 39. The compression spring 39 is limited on an inclined surface 381 of the connecting pipe 38, and a second sphere 310 is arranged between the inclined surfaces 381. The connecting pipe 38 communicates with a liquid collection box 311. When pressure is applied to the pressing plate 31, the compression spring 39 will be compressed. The second sphere 310 prevents the liquid in the connecting pipe 38 from flushing upward. The piston tube 36 pushes the liquid outwards. The first sphere 35 is lifted, and the rust-removing liquid flows out from the liquid collection box 311. When the hand is released, the compression spring 39 is released, the piston tube 36 moves upward, a low-pressure area is generated inside the piston tube 36 and the connecting pipe 38, causing the rust-removing liquid to rush upward, pushing open the second sphere 310, enabling the rust-removing liquid to flow into the low-pressure area. The first sphere 35 is stuck to the left in the limiting block 34 to prevent air from entering. When the first sphere 35 is pressed again, it is lifted, and the rust-removing liquid flows into the liquid storage cavity 301, and then is pushed towards the liquid outlet holes 32 to achieve the rust-removing function.

[0033] Further, in order to limit the rust removal component 3 to prevent liquid leakage and improve the use effect of the subsequent rust removal knife, specifically, the limiting component 4 includes an inclined groove 41, and the inclined groove 41 is provided on the surface of the pressing plate 31. A round block 42 is slidably connected in the inclined groove 41, and a sliding groove 43 is provided on the surface of the round block 42. The round block 42 is driven to slide or resist the limit in the inclined groove 41 by the movement of the sliding groove 43. A clamping block 44 is slidably connected in the sliding groove 43, and the clamping block 44 clamps a rotating rod 45. When the rotating rod 45 drives the round block 42 to slide to the lowest point of the inclined groove 41, the clamping block 44 also moves to the lowest point of the sliding groove 43 of the round block 42. At this time, the round block 42 contacts the inclined groove 41 and generates resistance, thereby restricting the further movement of the round block 42. One end of the rotating rod 45 is clamped with the clamping block 44, the other end of the rotating rod 45 is rotatably connected to the pressing plate 31, and a handle 46 is fixedly connected to the surface of the rotating rod 45. The rotation of the rotating rod 45 is driven by controlling the handle 46.

[0034] In the present utility model, during use, when using the rust removal knife for rust removal operation, the user holds the handle 1, aligns the blade of the knife body 2 with the rust on the metal surface. By applying a certain force and angle, the blade will cut into the rust layer and scrape it off. By pressing on the pressing plate 31, the compression spring 39 will be compressed. The sphere two 310 prevents the liquid in the connecting pipe 38 from flushing upward. The piston pipe 36 pushes the liquid outwards. The sphere one 35 is lifted, and the rust removal liquid flows out from the liquid collecting box 311. When the hand is released, the compression spring 39 is released. The piston pipe 36 moves upward, generating a low-pressure area in the piston pipe 36 and the connecting pipe 38, causing the rust removal liquid to rush upward, pushing open the sphere two 310, and enabling the rust removal liquid to flow into the low-pressure area. The sphere one 35 is stuck to the left in the limiting block 34 to prevent air from entering. When the sphere one 35 is pressed again and lifted, the rust removal liquid flows into the solution chamber 301 and is then pushed towards the liquid outlet hole 32 to achieve the rust removal function. By controlling the rotation of the rotating rod 45 driven by the handle 46, when the rotating rod 45 drives the round block 42 to slide to the lowest point of the inclined groove 41, the clamping block 44 also moves to the lowest point of the sliding groove 43 of the round block 42. At this time, the round block 42 contacts the inclined groove 41 and generates resistance, thereby restricting the further movement of the round block 42, limiting the rust removal component 3 to prevent liquid leakage, and improving the use effect of the subsequent rust removal knife.

[0035] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
