Technical Field

[0001] This utility model relates to the field of safety protection equipment technology, and in particular to an explosion-proof paint bucket. Background Technology

[0002] Explosion-proof paint buckets, as core equipment for storing and transporting flammable and explosive paints, are widely used in chemical, shipbuilding, oil extraction, and building coating industries. Their design must simultaneously meet explosion-proof safety standards and industrial operation requirements. With the strengthening of environmental regulations on the control of volatile organic compounds and the increasing demands for safe production in industrial settings, the development of explosion-proof paint buckets that combine safety, convenience, and durability has become an important issue in the industry. This device significantly improves operational efficiency and cleaning convenience without sacrificing explosion-proof performance, filling the gap in existing technologies where "safety requirements and industrial practicality are difficult to balance." It is particularly suitable for high-frequency use and high-safety-standard scenarios, and has significant engineering application value and market competitiveness.

[0003] However, existing explosion-proof paint buckets have the following disadvantages:

[0004] (1) When workers frequently take paint at the construction site, the operation is complicated and it is difficult to open the paint bucket quickly, which wastes a lot of working time.

[0005] (2) Commonly used pressure relief methods require electric or electronic components to drive, which can easily cause electric sparks and explosions, resulting in uncontrollable losses.

[0006] Therefore, this utility model provides an explosion-proof paint bucket. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem solved by this utility model is to provide a highly practical explosion-proof paint bucket, which solves the problems mentioned in the background art, such as the difficulty in quickly opening the paint bucket and the easy occurrence of electric spark explosions caused by electric or electronic components.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: an explosion-proof paint bucket, including a bucket body, a bucket lid provided on the top of the bucket body, flanges provided on the surfaces of both the bucket body and the bucket lid, an mounting block fixedly connected to one side of the flange, a circular groove provided on the surface of the mounting block, a groove provided on one side of both the mounting block and the flange, a fixing component provided inside the groove, a circular hole provided on the top of the bucket lid, and a pressure relief component provided on the surface of the circular hole;

[0011] The fixing component includes a threaded sleeve rotatably connected to the inner wall of the groove, a threaded rod threadedly connected to the inner wall of the threaded sleeve, a pressing block fixedly passing through one end of the threaded rod, the pressing block being rotatably connected to the inside of the circular groove, and a turntable fixedly connected to one end of the threaded rod.

[0012] The pressure relief assembly includes a circular block fixedly connected to the surface of a circular hole. The circular block has a cavity inside, and a limiting groove is formed in the inner top wall of the cavity. The cavity is connected to the inside of the circular hole, and an air vent is formed in the inner side wall of the cavity. A slider is slidably connected to the inner side wall of the cavity.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: an explosion-proof paint bucket, including a bucket body 1, a bucket lid 2 provided on the top of the bucket body 1, a flange 3 provided on the surface of both the bucket body 1 and the bucket lid 2, an mounting block 4 fixedly connected to one side of the flange 3, a circular groove provided on the surface of the mounting block 4, a groove provided on one side of both the mounting block 4 and the flange 3, a fixing component 5 provided inside the groove, a circular hole provided on the top of the bucket lid 2, and a pressure relief component 6 provided on the surface of the circular hole;

[0029] The fixing component 5 includes a threaded sleeve 501 rotatably connected to the inner wall of the groove. A threaded rod 502 is threadedly connected to the inner wall of the threaded sleeve 501. One end of the threaded rod 502 is fixedly connected to a pressing block 503, which is rotatably connected to the inside of the circular groove. One end of the threaded rod 502 is fixedly connected to a turntable 504. This eliminates the need for tools such as traditional bolts and clips. The turntable 504 directly drives the fixing, allowing locking and unlocking to be completed with one hand. This is suitable for frequent material handling scenarios, saving operation time. The self-locking characteristic of the threaded drive can prevent the lid from loosening due to transportation or vibration. It is more reliable than the spring 604 clip, and is especially suitable for tilted or inverted transportation scenarios.

[0030] The pressure relief assembly 6 includes a circular block 601 fixedly connected to the surface of a circular hole. The circular block 601 has a cavity inside, and a limiting groove is formed in the inner top wall of the cavity. The cavity is connected to the inside of the circular hole. An air vent is formed in the inner side wall of the cavity. A slider 602 is slidably connected to the inner side wall of the cavity. A circular rod 603 is fixedly inserted through the center of the slider 602. A spring 604 is connected between the slider 602 and the inner top wall of the cavity. The circular rod 603 is slidably connected inside the limiting groove. A sealing head 605 is fixedly connected to one end of the circular rod 603. Passive pressure relief is achieved through a purely mechanical structure, without the need for electricity or electronic components, avoiding the explosion caused by electric sparks. It meets the safety standards for explosion-proof environments. The pressure relief threshold is preset by the stiffness of the spring 604, which can be specifically adapted to the volatilization characteristics of different paints to prevent the barrel 1 from bursting due to gas accumulation.

[0031] A pressure gauge 7 is installed on the top of the lid 2. The pressure gauge 7 can be used to visually display the air pressure value inside the barrel, which is convenient for operators to monitor. The pressure gauge 7 is circular.

[0032] The bottom of the bucket 1 is fixedly connected with a support leg 8. The support leg 8 can reduce the shaking of the bucket and prevent paint from spilling or the bucket lid from hitting the ground and causing sparks due to tipping. The support leg 8 is rectangular.

[0033] One end of the support leg 8 is fixedly connected to a pad 9. The pad 9 increases the friction with the ground and further improves stability. There are three pads 9.

[0034] A reinforcing rod 10 is fixedly connected to one side of the support leg 8. The reinforcing rod 10 is used to prevent the support leg 8 from deforming or breaking and causing the bucket to tip over. A connecting block is fixedly connected to one end of the reinforcing rod 10.

[0035] A through hole is provided on the surface of the bucket body 1, and a glass 11 is installed inside the through hole. The remaining amount of paint in the bucket can be directly viewed through the glass 11.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: Rotate turntable 504 to drive threaded rod 502 to rotate inside threaded sleeve 501. Utilize the axial displacement characteristics of threaded transmission to make extrusion block 503 press or loosen flange 3 of barrel body 1 and barrel cover 2. Rotate turntable 504 clockwise, threaded rod 502 pushes extrusion block 503 forward, tightly fitting the two flanges 3. Uniform pressure is generated through the planar contact area of ​​extrusion block 503 to achieve sealing and fixation. Rotate turntable 504 counterclockwise, threaded rod 502 drives extrusion block 503 to retract, relieving pressure on flange 3, and barrel cover 2 can be easily removed. Threaded sleeve 501 is rotatably connected to mounting block 4 through groove, ensuring that the axial force of threaded rod 502 directly acts on extrusion block 503, avoiding free rotation or force deviation.

[0038] The second step: When the paint inside the bucket evaporates or the ambient temperature rises, causing the air pressure to exceed the safety threshold, the gas enters the cavity of the circular block 601 through the round hole, pushing the slider 602 upward to compress the spring 604; the slider 602 drives the round rod 603 and the sealing head 605 to move upward, exposing the vent to the cavity, and the gas is discharged out of the bucket through the vent, thus relieving pressure; when the air pressure drops to the safe range, the spring 604 pushes the slider 602 to reset, and the sealing head 605 re-blocks the round hole, restoring the sealing state.

[0039] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model.
