Description

Technical Field

[0001] The invention belongs to the technical field of metal end caps, in particular to a metal end cap with a quick disassembly and assembly function. Background Art

[0002] A head is a component used to seal the end of a container to isolate the internal and external media, also known as an end cap. The heads of cylindrical containers are generally rotating shells. According to the shape of the head surface, it can be divided into convex, conical, flat and combined shapes. A convex head refers to a head with a convex outer surface, such as a hemispherical, elliptical, dished and spherical head without folded edges. To meet different needs, the end caps of some sealed containers can be disassembled to maximize the opening of the sealed container. On the one hand, it is convenient to place large objects into the tank body, and on the other hand, it can also facilitate comprehensive cleaning, maintenance, and installation of equipment inside the sealed container.

[0003] A patent with the announcement number CN118183103B discloses a quick-assembly sealed container with a convenient snap-on head. The device uses a second driving member to make the head close to the tank body, and then uses multiple bolts arranged around the circumference to synchronously pass through the second flange and screw into the threaded holes on the first flange. After the head and the tank body are close to each other by the second driving member, the multiple bolts are used to lock the head and the tank body for a second time. Therefore, when the second driving member fails or malfunctions, the tank body and the head are tightly connected, which can effectively prevent leakage. When the head and the tank body are separated, the displacement generated by the unscrewing of the bolts generates a driving force to push the sealing airbag ring out of the second flange, making it easy to inspect the quality of the sealing airbag ring, thereby effectively improving the sealing effect when the head and the tank body are connected. In addition, when the bolts are unscrewed and the head is away from the tank body, the sliding arrangement of the bolts and the sprocket is used to generate a driving force to inflate the sealing airbag ring again, causing the sealing airbag ring to expand for easy inspection.

[0004] The above scheme still has some problems in actual application. The end cover and the tank body are tightly fitted together by hydraulic or pneumatic equipment, but the end cover needs to be tightly fitted with the tank body for a long time, which causes the hydraulic or pneumatic equipment to be in working condition for a long time and is prone to failure, resulting in a loose seal between the end cover and the tank body and leakage. Although the motor-driven belt drives the bolts to fasten the head and the tank body, disassembly is not convenient enough, and the installation of the sealed head and the tank body driven by hydraulic or pneumatic equipment makes it difficult to move and transport, resulting in problems such as limited use position and convenience of the head and the tank body.

[0021] 1.

[0022] 2. A metal head with a quick disassembly and assembly function according to the present invention is disengaged from the threaded hole by twisting the fastening bolt, and then driving the crank to rotate the threaded rod. At the same time, the threaded rod drives the cross slide plates to move closer to each other, thereby causing the cross slide plate to drive the push rod to move, and the push rod drives the U-shaped fixing block to drive the push plate to slide out of the cross slide groove, thereby causing the push plate to be threadedly connected to the threads of the inner wall of the through hole by a plurality of threaded blocks.

At the same time, the mounting block drives the sealing disk to slide downward in the tank cavity, thereby squeezing the tank cavity, thereby reducing the volume of the tank cavity. When the tank cavity needs to be pressurized, the volume of the tank cavity is compressed by the sealing disk, thereby increasing the pressure in the tank cavity. When the tank cavity needs to be depressurized, the sealing disk is driven to slide into the head, thereby increasing the volume of the tank cavity. Therefore, when the pressure in the tank cavity is too high, the pressure storage capacity is increased by increasing the volume in the tank cavity to reduce the pressure in the tank cavity.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1: Figures 1 to 9 As shown, a metal head with a quick disassembly and assembly function according to an embodiment of the present invention includes a head 1 and a tank body 2 connected to the head 1. A rubber sealing ring is installed in the lower end of the head 1, and a mounting and fixing component 4 is provided in the upper end of the head 1.

[0036] The mounting and fixing assembly 4 includes a rotating groove 41 provided inside the head 1, the inner cavity of the rotating groove 41 is rotatably connected to a rotating disk 42, and four arc-shaped grooves 43 are provided on one side of the rotating disk 42, and the inner cavity of each arc-shaped groove 43 is slidably connected to a limiting column 47, a telescopic rod 48 is installed outside the limiting column 47, and a clamping rod 49 is fixed to one end of the telescopic rod 48, and the rotating disk 42 is used to drive the limiting column 47 to drive the telescopic rod 48 to slide inside the rotating groove 41, and can drive the clamping rod 49 to clamp and fix the tank body 2, so that the head 1 and the tank body 2 are fixedly installed;

[0037] A fastening assembly 5 is provided at one end of the clamping rod 49;

[0038] The fastening assembly 5 includes a clamping block 51 fixed to one end of the clamping rod 49, a through slot 52 is provided on one side of the clamping block 51, and a stop block 53 is rotatably connected to the inner cavity of the through slot 52. When the clamping rod 49 clamps the tank body 2, the stop block 53 can be driven to push the tank body 2 to abut and fasten it with the head 1.

[0039] Specifically, welding is usually used in the prior art to fix the head and the tank body. However, this installation method cannot be used to disassemble the head and open the tank body later, making it difficult to clean the tank cavity. In addition, the weld is exposed to the outside for a long time and is corroded by the chemical agents in the tank body, which is prone to leakage. The detachable head is usually driven by hydraulic or pneumatic equipment to merge and fit the end cover with the tank body. However, the end cover needs to be in close contact with the tank body for a long time, which causes the hydraulic or pneumatic equipment to be in working state for a long time, which is prone to failure, resulting in a loose seal between the end cover and the tank body, resulting in leakage. In addition, the head and tank body driven by the hydraulic or pneumatic equipment to seal are difficult to move and transport, resulting in the problem of limited use position and convenience of the head and tank body.

[0040] When the head 1 is installed on the tank body 2, the present invention installs the head 1 on the upper end of the tank body 2, drives the rotating disk 42 to rotate, and makes the rotating disk 42 use the arc groove 43 to drive the limiting columns 47 to move closer to each other, and the limiting columns 47 drive the telescopic rod 48 to slide into the inner cavity of the rotating disk 42, and at the same time the telescopic rod 48 drives the clamping rod 49 to clamp and fix the outside of the tank body 2, so that the head 1 can be quickly fixed and installed with the tank body 2 and disassembled, avoiding the existing head 1 being fixed and installed with the tank body 2 by welding, which makes it difficult to disassemble the head 1 when the inner cavity of the tank body 2 needs to be cleaned or the head 1 needs to be replaced. While the clamping rod 49 is used to clamp and fix the tank body 2, the clamping block 51 is driven by the clamping rod 49 The tank body 2 is clamped and fixed, and at the same time, the clamping block 51 drives the retaining block 53 to fit and abut against the surface of the tank body 2, and then the clamping rod 49 drives the clamping blocks 51 to move closer to each other, so that the retaining block 53 abuts against the surface of the tank body 2 and is flipped over. At the same time, during the flipping process, the retaining block 53 pushes the surface of the tank body 2 to move close to the head 1, so that the tank body 2 abuts against the head 1, so that the tank body 2 squeezes the rubber sealing ring at the lower end of the head 1, thereby ensuring the sealing of the connection between the tank body 2 and the head 1, and as the rotating disk 42 continues to rotate, the clamping rod 49 will be used to drive the clamping block 51 to move, and the clamping block 51 will drive the retaining block 53 to continuously push the tank body 2 and the head 1 for extrusion, thereby improving the tightness of the connection, thereby solving the above-mentioned problem.

[0041] like Figure 1 、 Figures 4 to 6 As shown, a gear ring 44 is installed in the inner cavity of the rotating disk 42, and a gear 45 is meshed and connected in the inner cavity of the gear ring 44. A handle 46 is fixed to the upper end of the gear 45, and the handle 46 is rotatably connected to the head 1 and can be installed and fixed to the head 1.

[0042] Specifically, when the head 1 and the tank body 2 are fixedly installed, the handle 46 is driven to rotate, and the handle 46 drives the gear 45 to rotate, and at the same time, the gear 45 engages the transmission ring gear 44 to rotate, thereby driving the rotating disk 42 to rotate. During the rotation of the rotating disk 42, the arc groove 43 is used to drive the limit columns 47 to move closer to each other. At the same time, the limit columns 47 drive the telescopic rod 48 to move synchronously, thereby driving the clamping rod 49 and the clamping block 51 to clamp and fix the tank body 2. In the process of clamping the tank body 2, the clamping block 51 drives the block 53 to push the tank body 2 and the head 1 to be more tightly connected and fixed, thereby ensuring the sealing of the inner cavity of the tank body 2, and facilitating the rapid disassembly and installation of the head 1, thereby improving the convenience of using the head 1.

[0043] like Figures 3 to 5 As shown in FIG9 , the inner cavity of the through slot 52 is rotatably connected to a rotating shaft 54 ​​, and the rotating shaft 54 ​​is located outside the inner cavity of the clamping block 51 and is fixedly connected to a fixed disk 56 . A torsion spring 55 is fixedly connected to one side of the fixed disk 56 , and one end of the torsion spring 55 is fixedly connected to the inner cavity wall of the clamping block 51 .

[0044] like Figures 3 to 5 As shown in FIG9 , the outer portion of the rotating shaft 54 ​​is fixedly mounted to the stop block 53 . One side of the stop block 53 is provided with an inclined surface, and anti-slip teeth are evenly arranged on the inclined surface.

[0045] Specifically, when the driving clamp rod 49 drives the clamp block 51 to install and fix the tank body 2 and the head 1, the clamp block 51 drives the rotating shaft 54 ​​to move, and the rotating shaft 54 ​​drives the block 53 to move synchronously, so that the block 53 uses the inclined surface to abut against the surface of the tank body 2, and the inclined surface of the block 53 is evenly provided with anti-slip teeth, so that when the block 53 is used to clamp and push the tank body 2, the block 53 drives the rotating shaft 54 ​​to rotate, and the rotating shaft 54 ​​drives the fixed plate 56 to rotate, and the fixed plate 56 drives the torsion spring 55 to twist, and then the torsion of the torsion spring 55 is used to twist the fixed plate 56, and the fixed plate 56 drives the rotating shaft 54 ​​to rotate and return. The stop block 53 is positioned so that the rotating shaft 54 ​​drives the stop block 53 to better clamp and fix with the surface of the tank body 2. At the same time, the stop block 53 can also push the tank body 2 close to the head 1 for abutment and fixation, preventing the stop block 53 from being difficult to effectively abut and push the surface of the tank body 2 close to the head 1 to move, causing the tank body 2 and the head 1 to be difficult to tightly abut and seal. This solves the problem that after the existing metal head with quick disassembly and assembly function is installed and fixed with the head and the tank body, if the tank body and the head are not further pushed close to each other to ensure the stability of the installation point of the head and the tank body, the tank body will be under high pressure for a long time after being subjected to high pressure, and the tank body and the head will be prone to leakage.

[0046] like Figure 4 and Figure 3 As shown, a sealing disk 8 is slidably connected to the inner cavity of the head 1, and a rubber sealing gasket is provided on the outside of the sealing disk 8. A pressure monitor 9 is provided in the middle of the lower end of the sealing disk 8.

[0047] like Figure 1 and Figures 4 to 6 As shown, a through hole 13 is opened at the upper end of the head 1, and the inner wall of the through hole 13 is provided with a thread. An internal pressure monitoring component 3 is installed at one end of the sealing disk 8, and the internal pressure monitoring component 3 is used to monitor the storage amount of liquid and gas in the inner cavity of the tank body 2 in real time, and can also adjust the volume in the inner cavity of the tank body 2 as needed.

[0048] Specifically, after the tank body 2 and the head 1 are installed and fixed, the pressure in the inner cavity of the tank body 2 can be received by using the pressure monitor 9, and the pressure monitor 9 can be transmitted to the external controller for display through a signal. In addition, liquid or gas is injected into the inner cavity of the tank body 2, and then the sealing disk 8 is pushed by the liquid or gas to slide in the inner cavity of the tank body 2, and the internal pressure monitoring component 3 is pushed by the sealing disk 8 to slide inside the head 1 to detect the position and capacity of the liquid or gas in the inner cavity of the tank body 2, thereby solving the problem that after the existing metal head with a quick disassembly and assembly function is installed and fixed to the tank body, it is usually difficult to observe the internal situation because the head and the tank body are fixed and sealed. This makes it difficult to observe the capacity of the liquid and gas inside the tank body after liquid and gas are poured into the tank body, and at the same time monitor the pressure in the inner cavity of the tank body so as to timely relieve the pressure of the tank body and prevent the internal pressure of the tank body from overloading and leaking.

[0049] Example 2: Figure 1 、 Figure 7 and Figure 8 As shown, the internal pressure monitoring assembly 3 includes a mounting block 10 mounted on the upper end of the sealing disk 8, the upper end of the mounting block 10 is rotatably connected to a sliding post 31, the upper end of the sliding post 31 is fixedly connected to a knob 6, a scale number is set on the outside of the sliding post 31, and the sliding post 31 is slidably connected to the inner cavity of the through hole 13.

[0050] like Figure 1 、 Figure 7 and Figure 8 As shown, a cross slot 32 is provided inside the slide column 31, and four push plates 38 are slidably connected to the inner cavity of the cross slot 32. A plurality of threaded blocks are provided on one side of each push plate 38, and the push plates 38 are threadedly connected to the inner wall of the through hole 13 through the threaded blocks.

[0051] like Figure 2 、 Figure 7 and Figure 8 As shown, the inner cavity of the cross slide 32 is rotatably connected to a rotating column 33, both ends of the rotating column 33 are fixed with threaded rods 34, the external thread of the threaded rod 34 is connected to a cross slide 35, the inner cavity of the cross slide 35 is rotatably connected to a push rod 36, one end of the push rod 36 is rotatably connected to a U-shaped fixing block 37, and one end of the U-shaped fixing block 37 is fixed to a push plate 38.

[0052] like Figure 6 、 Figure 7 and Figure 8 As shown, one end of the threaded rod 34 passes through the sliding column 31 and is fixed to the crank 7. One end of the crank 7 is internally threadedly connected to the fastening bolt 11. A plurality of threaded holes 12 are opened on the upper end of the knob 6, and the fastening bolt 11 is threadedly connected and fixed to the threaded holes 12.

[0053] The screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, and the screw threaded rod 34 is screwed to the screw threaded hole 12, When the pressure in the tank body 2 is reduced, the sealing disc 8 is driven to slide into the head 1, thereby increasing the volume of the tank body 2. When the pressure in the tank body 2 is too high, the volume in the tank body 2 is increased, the pressure storage capacity is increased, and the pressure in the tank body 2 is reduced. This solves the problem that the existing metal head with a quick disassembly and assembly function cannot change the volume in the tank body after the head is installed and fixed to the tank body, resulting in excessive pressure in the tank body. The pressure will accumulate at the sealed connection between the head and the tank body. If the pressure in the tank body cannot be reduced in time, the pressure overload will cause the connection between the head and the tank body to burst.

[0054] Working principle: when installing the head 1 and the tank body 2, the head 1 is installed on the upper end of the tank body 2, and the rotating disk 42 is driven to rotate at the same time, and the rotating disk 42 uses the arc groove 43 to drive the limit columns 47 to move close to each other, and the limit columns 47 will drive the telescopic rod 48 to slide into the inner cavity of the rotating disk 42. At the same time, the telescopic rod 48 drives the clamping rod 49 to clamp and fix the outside of the tank body 2, so that the head 1 can be quickly fixed and installed with the tank body 2 and disassembled, avoiding the existing head 1 being fixed and installed with the tank body 2 by welding, which makes it difficult to clean the inner cavity of the tank body 2 or replace the head 1. 1 is troublesome to disassemble, and while the clamping rod 49 is used to clamp and fix the tank body 2, the clamping block 51 is driven by the clamping rod 49 to clamp and fix the tank body 2, and at the same time, the clamping block 51 drives the abutting block 53 to fit and abut against the surface of the tank body 2, and then as the clamping rod 49 drives the clamping blocks 51 to move closer to each other, the abutting block 53 abuts against the surface of the tank body 2 and then flips over. At the same time, during the flipping process, the abutting block 53 pushes the surface of the tank body 2 to move closer to the head 1, thereby abutting the tank body 2 and the head 1, so that the tank body 2 squeezes the rubber sealing ring at the lower end of the head 1, thereby ensuring the sealing of the connection between the tank body 2 and the head 1;

[0055] The locking mechanism 53 is moved by the spring 55 and the locking mechanism 56 is moved to the left and right, so that the locking mechanism 53 is locked and locked.

[0056] When the volume of the inner cavity of the tank body 2 needs to be adjusted, the fastening bolt 11 is disengaged from the threaded hole 12 by twisting the fastening bolt 11, and then the fastening bolt 11 is used to drive the crank 7 to rotate, and the crank 7 drives the threaded rod 34 to rotate, and at the same time the threaded rod 34 drives the rotating column 33 to rotate, and then drives another threaded rod 34 to rotate, and at the same time the threaded rod 34 drives the cross slide 35 to slide in the inner cavity of the cross slide 32 and move close to each other, thereby driving the cross slide 35 to drive the push rod 36 to move, and the push rod 36 pushes the U-shaped fixing block 37 to move, and at the same time the U-shaped fixing block 37 drives the push plate 38 to slide out of the cross slide 32, and a plurality of threaded blocks are evenly arranged on one side of the push plate 38, so that the push plate 38 can be threadedly connected with the threads on the inner wall of the through hole 13 by using the plurality of threaded blocks, and then the knob is driven. 6 drives the slide post 31 to rotate, and the slide post 31 drives the pushing plate 38 to perform threaded transmission with the inner wall thread of the through hole 13, thereby causing the slide post 31 to push the mounting block 10 to move downward, and at the same time the mounting block 10 pushes the sealing plate 8 to slide downward in the inner cavity of the tank body 2, and then uses the sealing plate 8 to squeeze the inner cavity of the tank body 2, thereby reducing the volume of the inner cavity of the tank body 2, and when it is necessary to pressurize the inner cavity of the tank body 2, the volume in the inner cavity of the tank body 2 is compressed by the sealing plate 8, thereby increasing the pressure in the inner cavity of the tank body 2, and when the pressure in the inner cavity of the tank body 2 is reduced, the sealing plate 8 is driven to slide into the interior of the head 1, thereby increasing the volume in the inner cavity of the tank body 2, thereby achieving when the pressure in the inner cavity of the tank body 2 is too high, by increasing the volume in the inner cavity of the tank body 2, increasing the pressure storage capacity and reducing the pressure in the inner cavity of the tank body 2.
