Description

Technical Field

[0001] The invention relates to the technical field of paint bucket sealing equipment, and in particular to a cover body and a manufacturing method thereof. Background Art

[0002] Ship painting is an important measure to ensure the safety and service life of ships. The paint forms a protective layer on the surface of the ship, thereby preventing seawater and humid air from corroding the metal structure on the surface of the ship, ensuring that the ship has strong durability and anti-corrosion performance. In industrial manufacturing, paint buckets are usually used to hold paint. During the ship painting construction process, the surface of the workpiece after painting needs to be inspected and repaired to prevent defects such as low film thickness, sagging, bubbles, particles, etc. This requires the staff to hold a small paint bucket to perform paint repair work on the surface of the workpiece.

[0003] The structure of the paint bucket in the prior art is usually a bucket cover on the bucket body. During the storage and transportation of the paint, the bucket cover is fixed on the bucket body to prevent the paint from spilling. When using the paint, the staff needs to remove the entire bucket cover from the bucket body, and the paint in the bucket body is completely exposed. The paint dries quickly, and there is a risk of accidental overturning of the bucket body causing leakage of hazardous chemicals, or due to open flame operations on the ship, sparks fall into the inside of the bucket body, which poses a great safety hazard. In addition, when using tools for repair, it is inconvenient to place the tools in the existing usage method. Summary of the invention

[0007] A cover plate is detachably covered on the barrel body, and an operation hole communicating with the barrel body is provided on the cover plate;

[0008] The partial cover can be selectively buckled on the operating hole; the partial cover is provided with an avoidance notch and a bending portion, when the partial cover is buckled on the operating hole, the avoidance notch can leave a placement space for the painting tool, and the bending portion protrudes above the partial cover.

[0009] Preferably, the partial cover is connected to the cover plate via a hinge.

[0010] Preferably, the bending portion and the partial cover are formed integrally.

[0011] Preferably, the cover body further comprises a skirt, which is arranged at the edge of the cover plate, folded toward a side away from the bending portion, and extends along the axial direction of the cover plate, and the skirt can cooperate with the barrel body.

[0012] Preferably, a sealing groove is provided along the circumference of one side of the skirt that cooperates with the barrel body, and a sealing ring is installed in the sealing groove.

[0013] Preferably, the skirt is threadedly connected or snap-fitted to the barrel body.

[0014] Preferably, a locking mechanism is further included for locking the cover plate and the partial cover.

[0015] Preferably, a detection mechanism is provided on the cover body, and the detection mechanism is used to detect the temperature of the barrel body.

[0016] Preferably, a handle is also provided on the cover plate.

[0017] A method for manufacturing a cover body, used for manufacturing the above-mentioned cover body, comprises the following steps:

[0018] S1, cutting a first circular iron sheet to make the cover plate;

[0019] S2, cutting a second circular iron sheet to make the partial cover;

[0020] S3, installing the partial cover on the cover plate;

[0021] The step S1 also includes S11: opening a circular hole on the first circular iron sheet as the operating hole; the step S2 also includes S21: cutting a portion of the second circular iron sheet and bending it upward as the bending portion, and the empty portion on the second circular iron sheet serves as the avoidance gap.

[0022] Beneficial effects of the present invention:

[0023] The present invention provides a cover body and a manufacturing method thereof, wherein the cover body comprises a cover plate and a partial cover, wherein the cover plate is detachably covered on a barrel body and an operating hole connected to the barrel body is provided on the cover plate, and the partial cover can be selectively buckled in the operating hole. The original barrel cover of the barrel body is removed and replaced with the present cover body, and when the paint needs to be used, the partial cover is placed in an open position relative to the operating hole, and the paint is loaded and taken from the operating hole. In terms of practicality, the cover body of the present invention has a simple structure, light weight, and is easy to carry. The cover body can be installed on different barrel bodies of the same size, which is safe, reliable, and highly practical. Specifically, the cover body can be used in ship painting work, for example, in scenes where paint needs to be frequently taken, color matching, and small-scale repair work, to avoid loss caused by frequent opening and closing of the entire cover body and reduce the life of the cover body. It is also suitable for scenes with narrow working spaces, without removing the entire cover body, to avoid inconvenience in operation due to narrow operating space, and is also suitable for scenes where fine coating processes are required, and the operating hole can provide fine dosage control to ensure uniform distribution and precise use of the paint. In terms of safety, there is no need to open the entire cover when loading and unloading the paint. Compared with the method of opening the entire cover when loading and unloading the paint, the direct exposure area of ​​the paint is reduced, the drying rate of the paint is reduced, and the cover can also reduce the probability of sparks falling into the barrel; and when loading and unloading the paint, the cover is still covered on the barrel, which has good firmness. Even when the barrel accidentally overturns, the cover can limit the flow rate of the paint and reduce the possibility of paint overflow or splashing, thereby reducing the risk of accidents and even environmental pollution accidents caused by paint spillage and leakage. Secondly, when it is necessary to add paint or other additives to the barrel, the operation can be performed without completely opening the cover, which helps to keep the environment inside the barrel clean. In terms of environmental protection, there is no need to open the entire cover when loading and unloading the paint, which reduces the area of ​​contact between the paint and the air and helps to reduce the emission of volatile organic compounds.

[0024] In addition, the partial cover is provided with an avoidance notch and a bending part. The avoidance notch can leave space for the painting tools when the partial cover is buckled into the operating hole. At this time, the partial cover can further reduce the exposed area of ​​the paint, and at the same time play the role of blocking sparks and reducing the flow rate of the paint after the barrel is dumped. The bending part is raised above the partial cover, and the staff can operate the partial cover through the bending part, which improves the portability of the operation.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] Reference Figure 1 and Figure 2The present invention provides a cover body and a manufacturing method thereof. The cover body comprises a cover plate 1 and a partial cover 2. The cover plate 1 is detachably covered on the barrel body and an operation hole 11 connected to the barrel body is provided on the cover plate 1. The partial cover 2 can be selectively buckled in the operation hole 11. The original barrel cover of the barrel body is removed and replaced with the cover body. When the paint needs to be used, the partial cover 2 is in an open position relative to the operation hole 11, and the paint is loaded and taken from the operation hole 11. When loading and taking the paint, it is not necessary to open the entire cover body. Compared with the method of opening the entire cover body when loading and taking the paint, the direct exposure area of ​​the paint is reduced, the drying rate of the paint is reduced, and the cover body can also reduce the probability of sparks falling into the barrel body; and when loading and taking the paint, the cover body is still covered on the barrel body, and has good firmness. Even when the barrel body is accidentally overturned, the cover body can limit the flow rate of the paint, reduce the possibility of the paint overflowing or splashing, thereby reducing the risk of accidents and even environmental pollution accidents caused by paint spillage and leakage, reducing the area of ​​contact between the paint and the air, and helping to reduce the emission of volatile organic compounds. Secondly, when it is necessary to add paint or other additives into the barrel, the operation can be performed without completely opening the cover, which helps to keep the environment inside the barrel clean.

[0034] In addition, the partial cover 2 is provided with an avoidance notch 21 and a bend 22. The avoidance notch 21 can leave space for the painting tools when the partial cover 2 is buckled into the operating hole 11. At this time, the partial cover 2 can further reduce the exposed area of ​​the paint, and at the same time play a role in blocking sparks and reducing the flow rate of the paint after the barrel is dumped. The bend 22 protrudes above the partial cover 2, and the staff can operate the partial cover 2 through the bend 22, which improves the portability of the operation. This cover is suitable for scenes where frequent access to paint is required, as well as scenes of color matching and small-scale repair work, to avoid loss caused by frequent opening and closing of the entire cover and reduce the life of the cover. It is also suitable for scenes with small working spaces, without removing the entire cover, to avoid inconvenience in operation due to small operating space. It is also suitable for fine coating processes, and the operating hole 11 can provide fine dosage control to ensure uniform distribution and precise use of paint.

[0035] The partial cover 2 is connected to the cover plate 1 through a hinge 3, and the partial cover 2 is moved on the cover plate 1 through the hinge 3. The hinge 3 has good durability and saves maintenance and replacement costs. In this embodiment, the hinge 3 adopts a hinge structure, and the hinge structure includes two pages and a page axis. The two pages are rotatably connected to the page axis, one of which is connected to the partial cover 2, and the other is connected to the cover plate 1, so that the partial cover 2 and the cover plate 1 can rotate around the page axis, that is, the partial cover 2 can rotate around the page axis to buckle or open the operating hole 11. In addition, damping can be added to the hinge structure, and the damping can buffer the mutual rotation between the partial cover 2 and the cover plate 1, thereby slowing down the closing and opening speed of the partial cover 2, reducing the noise generated by the collision between the partial cover 2 and the cover plate 1, and improving the experience of the staff. In other embodiments, the partial cover 2 and the cover plate 1 can also be set to be split or slidably connected.

[0036] Furthermore, the cover body also includes a locking mechanism for locking the cover plate 1 and the partial cover 2. The locking mechanism is provided to improve the stability of the partial cover 2 being buckled on the cover plate 1. Specifically, the locking mechanism may be a buckle assembly, which includes two buckles, one of which is mounted on the partial cover 2, and the other is mounted on the cover plate 1. When the partial cover 2 is buckled with the operating hole 11, the partial cover 2 is fixed to the cover plate 1 through the buckle assembly. Of course, the locking mechanism may also be a magnetic attraction assembly, which includes two mutually attractive magnetic poles, one of which is mounted on the partial cover 2, and the other is mounted on the cover plate 1. When the partial cover 2 is buckled with the operating hole 11, the partial cover 2 is fixed to the cover plate 1 through the magnetic attraction force.

[0037] The partial cover 2 is provided with a bending portion 22, and the bending portion 22 and the partial cover 2 are integrally formed, which reduces production steps, improves production efficiency, and helps reduce production costs. At the same time, the connection between the bending portion 22 and the partial cover 2 is also smoother, reducing seams and defects, and improving the overall aesthetics of the partial cover 2. Of course, the bending portion 22 can also be welded to the partial cover 2, and the bending portion 22 is specifically a handle, which is connected to the partial cover 2 by welding.

[0038] In order to realize the connection between the cover body and the barrel body, the cover body also includes a skirt 4, which is arranged at the edge of the cover plate 1 and folded toward the side away from the bending portion 22, and extends downward along the axial direction of the cover plate 1. When the cover body is installed on the barrel body, the skirt 4 and the barrel body cooperate with each other, and the connection strength is higher. Specifically, the skirt 4 is provided with threads, and the barrel body is also provided with threads correspondingly. The cover body is installed on the barrel body by threaded connection, which not only improves the connection strength between the cover body and the barrel body, but also improves the convenience of connection and disassembly between the cover body and the barrel body, and the sealing is better. In other embodiments, a connecting buckle can also be provided on the cover plate 1, and the cover body is connected to the barrel body through the connecting buckle, or a friction component can be provided on the skirt 4, and the cover body is connected to the barrel body through the friction force of the friction component.

[0039] Furthermore, the inner diameter of the skirt 4 matches the outer diameter of the barrel body to ensure a tight connection between the two. When the cover body is installed on the barrel body, the skirt 4 is wrapped around the outer side of the barrel body, and accordingly, the skirt 4 is provided with an internal thread, and the barrel body is correspondingly provided with an external thread. Of course, in other embodiments, the skirt 4 may be wrapped around the inner side of the barrel body, and the outer diameter of the skirt 4 matches the inner diameter of the barrel body, and accordingly, the skirt 4 is provided with an external thread, and the barrel body is correspondingly provided with an internal thread.

[0040] A sealing groove is also provided along the circumference of one side where the skirt 4 cooperates with the barrel body, and a sealing ring is installed in the sealing groove. When the skirt 4 cooperates with the barrel body, the sealing ring can improve the sealing between the cover body and the barrel body. In this embodiment, since the inner diameter of the skirt 4 matches the outer diameter of the barrel body, the sealing groove is provided on the inner circumference of the skirt 4, and the sealing ring is installed in the sealing groove, so that when the cover body is installed on the barrel body, the sealing ring can ensure the sealing strength between the cover body and the barrel body. In other embodiments, when the outer diameter of the skirt 4 matches the inner diameter of the barrel body, the corresponding sealing groove is provided on the outer circumference of the skirt 4, and the sealing ring is installed in the sealing groove.

[0041] The skirt 4 and the cover plate 1 are connected by a sheet metal edging process, which enhances the flatness of the connection, makes the appearance of the cover body more neat, and enhances the structural stability. The cover plate 1, the partial cover 2, the skirt 4 and the barrel body are all made of fire-retardant materials, specifically metal iron sheet support, which has good chemical stability, corrosion resistance and sufficient mechanical strength.

[0042] In addition, in order to facilitate the staff to hold the cover body, a handle 5 is also provided on the cover plate 1. Preferably, the operation hole 11 is eccentrically arranged on the cover plate 1, so that the operator can load and take the paint in the barrel through the operation hole 11; the handle 5 is arranged in the middle of the cover plate 1, so that the force is more uniform when the cover plate 1 is opened. At the same time, the operation hole 11 and the handle 5 do not interfere with each other. Specifically, the handle 5 is also made of fire-retardant material.

[0043] In order to ensure the safety of the paint in the barrel, a detection mechanism and a pressure relief mechanism are also provided on the cover. The detection mechanism is used to detect the temperature of the barrel, and the pressure relief mechanism can release the pressure in the barrel to the outside of the barrel. The detection mechanism can detect the temperature of the barrel in real time. When the paint in the barrel reaches a certain temperature, the pressure relief mechanism starts to work and releases the internal pressure of the barrel to prevent the paint in the barrel from exploding due to gas expansion in a sealed environment for a long time. Exemplarily, the detection mechanism can be a thermometer and the pressure relief mechanism can be a pressure relief valve.

[0044] The present invention also provides a method for manufacturing the cover as described above:

[0045] S1, cutting a first circular iron sheet to make a cover plate 1;

[0046] S2, cutting a second circular iron sheet to make a partial cover 2;

[0047] S3, installing the local cover 2 on the cover plate 1;

[0048] Step S1 also includes S11: opening a round hole on the first circular iron sheet as the operation hole 11; step S2 also includes S21: cutting a portion of the iron sheet on the second circular iron sheet and bending it upward as the bending portion 22, and the vacant portion on the second circular iron sheet as the avoidance notch 21. This method is easy to operate and easy to implement, and provides greater convenience for the production of the cover.

[0049] Preferably, in step S1, a first circular iron sheet with a diameter of 22 mm is cut to make the cover plate 1, and a circular hole with a diameter of 5 mm is opened in the first circular iron sheet at a position 5 mm away from the center of the circle as an operating hole 11. In step S2, a second circular iron sheet with a diameter of 7.5 mm is cut to make the partial cover 2.

[0050] Furthermore, the bottom circumference of the skirt 4 is 80 mm and the width is 5 mm.
