DETAILED DESCRIPTION

[0019] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0022] like Figure 1 and Figure 3 As shown, the present invention proposes a sealing structure of an HDPE ultra-clean barrel, which is used to seal the water outlet 2 on the barrel body 1. The liquid inside the barrel body 1 can be discharged through the water outlet 2. A conical barrel cover 3 is provided inside the water outlet 2. The water outlet 2 and the conical barrel cover 3 are in conflict with each other. The water outlet 2 and the conical barrel cover 3 are fitted together to achieve a sealing effect; it also includes at least two connecting rods 4 supporting the conical barrel cover 3. The connecting rods 4 are fixedly connected to the outer side of the conical barrel cover 3, and the connecting rods 4 can support the conical barrel cover 3.

[0023] As an implementation method, Figure 3 and Figure 4As shown, the sealing structure of the HDPE ultra-clean barrel also includes an elastic pulling mechanism sleeved on the outside of the connecting rod 4, which is used to pull the connecting rod 4 downward so that the conical barrel cover 3 is tightly fitted with the water outlet 2. When the elastic pulling mechanism is working, it will be in a state of pulling the connecting rod 4. At this time, the connecting rod 4 will be in a downward state under the action of the elastic pulling mechanism, and the downward movement of the connecting rod 4 will drive the conical barrel cover 3 to move downward. The downward movement of the conical barrel cover 3 will be blocked by the water outlet 2, and then it will be tightly connected with the water outlet 2. This prevents liquid leakage. When the initial contact surface of the conical barrel cover 3 contacting the water outlet 2 is aged and compressed, the elastic pulling mechanism is in a state of long-term pulling of the conical barrel cover 3. The conical barrel cover 3 is still in a downward state at this time, and the aged and compressed contact surface of the conical barrel cover 3 will move downward accordingly. The other unfitted surfaces of the conical barrel cover 3 will move downward synchronously to replace the aged and compressed contact surface and fit tightly with the water outlet 2 again. There will be no gap between the two due to the aging and compression of the conical barrel cover 3, which will affect the sealing.

[0024] When the narrow side of the conical barrel cover 3 faces downward, the outer side of the conical barrel cover 3 will fit tightly against the inner wall of the water outlet 2 to achieve a sealing effect. When the liquid inside the barrel body 1 needs to be poured out, the conical barrel cover 3 is manually lifted and poured directly. Due to the large diameter of the water outlet 2, the liquid inside the barrel body 1 will diffuse along the inner wall of the water outlet 2, forming a radial diffusion phenomenon, causing the actual fluid outlet path to deviate from the preset path, thereby affecting the accuracy of the liquid flow direction.

[0025] In view of the above problems, the sealing structure of the HDPE ultra-clean barrel of this embodiment further includes a liquid collecting mechanism, such as Figure 3 、 Figure 4 and Figure 5 When the conical cover 3 is opened, the conical cover 3 is opened, and the conical cover 3 is opened, and the conical cover 3 is opened. When the conical cover 3 is opened, the conical cover 3 is opened, and the conical cover 3 is opened. When the conical cover 3 is opened, the conical cover 3 is opened, and the conical cover 3 is opened. When the conical cover 3 is opened, the conical cover 3 is opened, and the conical cover 3 is opened. When the conical cover 3 is opened, the conical cover 3 is opened, and the conical cover 3 is opened. When the conical cover 3 is opened, the conical cover 3 is opened, and the conical cover 3 is opened.

[0026] Further, such as Figure 3 and Figure 4As shown, the elastic pulling mechanism includes a connecting plate 5, a limiting square tube 6, a fixing plate 1 7, a fixing plate 2 8 and a spring 1 9. The elastic pulling mechanism is described in detail below: The connecting plate 5 is rotatably connected to the outside of the connecting rod 4. The connection mode of the connecting plate 5 and the connecting rod 4 can ensure that the connecting plate 5 has a traction effect on the connecting rod 4 without affecting the normal rotation of the connecting rod 4. The limiting square tube 6 is slidably connected to the outside of the connecting plate 5, and the limiting square tube 6 is fixed to the outside of the barrel body 1. The barrel body 1 in this embodiment is made of stainless steel with a relatively high hardness. The fixing plate 1 7 and the fixing plate 2 8 are respectively fixed to the outsides of the connecting plate 5 and the limiting square tube 6. The two ends of the spring 1 9 are connected between the fixing plate 1 7 and the fixing plate 2 8. When the conical barrel cover 3 is fitted with the water outlet 2, the spring 1 9 will continuously apply a pulling force to the fixing plate 1 7. The fixing plate 1 7 is subjected to a force that drives the connecting plate 5 to move downward along the inside of the limiting square tube 6, and the connecting plate The connecting plate 5 moves downward, and then drives the conical barrel cover 3 to move downward through the connecting rod 4, so that the conical barrel cover 3 is tightly fitted with the water outlet 2, blocking the external medium from invading the interior of the barrel body 1 or the internal fluid of the barrel body 1 from leaking. When the internal liquid of the barrel body 1 needs to be discharged, the staff only needs to manually lift the conical barrel cover 3, and the conical barrel cover 3 is forced to move upward, breaking away from the fit with the water outlet 2, and the liquid inside the barrel body 1 can be poured in. Moreover, when the conical barrel cover 3 moves upward, the conical barrel cover 3 will drive the connecting plate 5 to move upward through the connecting rod 4, and the upward movement of the connecting plate 5 will pull the spring 9 through the fixed plate 7, causing the spring 9 to deform, and the elastic potential energy generated by the deformation of the spring 9 can support and pull the conical barrel cover 3 to return to its original position, and ensure that the conical barrel cover 3 is tightly fitted with the water outlet 2.

[0027] Furthermore, Figure 3 、 Figure 4 and Figure 5 As shown, the liquid collecting mechanism includes a guide groove 10 and a one-way valve. The liquid collecting mechanism is described in detail below: The guide groove 10 is opened inside the conical barrel cover 3, and the guide groove 10 is a conical design with a width at the top and a narrowness at the bottom. The one-way valve is installed inside the guide groove 10. The setting of the one-way valve can ensure that the liquid can flow from the wide mouth of the guide groove 10 to the narrow mouth, while the liquid cannot flow from the narrow mouth of the guide groove 10 to the wide mouth, thereby ensuring that when the conical barrel cover 3 seals the water outlet 2, it blocks the external medium from invading the interior of the barrel body 1 or the fluid inside the barrel body 1 from leaking. When the conical barrel cover 3 moves up and out of contact with the water outlet 2, it can be rotated. The conical barrel cover 3, at this time the wide mouth of the guide groove 10 faces the water outlet 2, and then the conical barrel cover 3 is loosened, the conical barrel cover 3 moves down and resets to fit the water outlet 2, and the guide groove 10 will be in close contact with the outer side of the water outlet 2 to achieve a certain sealing effect. Then when the internal liquid of the barrel body 1 is poured out, the liquid in the guide groove 10 follows the width design of the guide groove 10, and the flow rate is reduced from a large flow rate, thereby increasing the pressure of the liquid during flow, so that the liquid flows to the designated position. The designated position depends on the actual situation, reducing the diffusion of the liquid during flow.

[0028] Among them, such as Figure 6 、 Figure 7 and Figure 8 As shown, the conical barrel cover 3 fits tightly with the water outlet 2 under the action of gravity and the elastic potential energy of the spring 9. In order to prevent the conical barrel cover 3 from being accidentally touched, which causes the conical barrel cover 3 to be out of contact with the water outlet 2, this embodiment also includes a limiting mechanism. A limiting mechanism is provided on the periphery of the barrel body 1. The limiting mechanism includes a lifting plate 11, multiple groups of latches 12, a rotating assembly for supporting and rotating the lifting plate 11, and a latch assembly for limiting the movement of the lifting plate 11, wherein: the rotating assembly is connected to the outside of the connecting rod 4; the lifting plate 11 is connected to the rotating assembly, and the multiple groups of latches 12 are all fixed to the outside of the lifting plate 11. When the connecting plate 5 moves downward, the connecting plate 5 drives the lifting plate 11 to move downward synchronously through the rotating assembly, and the downward movement of the lifting plate 11 will drive the multiple groups of latches 12 to move downward; the latch assembly is connected to the outside of the barrel body 1, and the latch assembly can The locking teeth 12 are in a blocking state so as to prevent the lifting plate 11 from moving upward. When the latch teeth 12 move downward, the inclined surface of the latch teeth 12 will contact the locking assembly. The locking assembly will move under the force at this time, providing space for the latch teeth 12 to move downward. When each group of latch teeth 12 moves downward and contacts the locking assembly, the locking assembly will move. When the latch teeth 12 pass over the locking assembly, the locking assembly will immediately reset and then repeat the above action. When the conical barrel cover 3 is accidentally touched and causes the conical barrel cover 3 to move upward, the latch teeth 12 are synchronously in an ascending state at this time. When the latch teeth 12 rise, the plane of the latch teeth 12 is blocked by the locking assembly, resulting in the inability to move upward normally, thereby ensuring the fixation of the position of the conical barrel cover 3 and playing the role of preventing accidental touch. When the conical barrel cover 3 needs to be moved upward, it is only necessary to continuously separate the locking assembly from the control of the latch teeth 12.

[0029] As an implementation method, Figure 7 and Figure 8 As shown, the clamping assembly includes a clamping plate 13, a horizontal plate 14, a pair of limiting rods 15, a side plate 16 and a spring 2 17. The clamping assembly is described in detail below: The card plate 13 is fitted with the lifting plate 11. When the lifting plate 11 moves downward, it will drive the inclined surface of the tooth 12 to squeeze the card plate 13. When the card plate 13 is subjected to force, it will move in the direction away from the lifting plate 11. The cross plate 14 is fixed to one end of the card plate 13 away from the tooth 12. The movement of the card plate 13 will drive the cross plate 14 to move. A pair of limiting rods 15 are both slid inside the cross plate 14. The cross plate 14 moves along the pair of limiting rods 15 at this time. The side plate 16 is fixed to the two ends of the pair of limiting rods 15, and the side plate 16 is fixed to the outside of the barrel body 1. The two ends of the spring 2 17 are respectively fixed to the end of the cross plate 14 away from the card plate 13 and the side plate 16. When the latch 12 is moved upwards, the plane of the latch 12 is blocked by the latch 13 and cannot move. When the latch 12 needs to be moved upwards, it is only necessary to pull the latch 13 in the direction away from the lifting plate 11 so that the latch 13 continues to break away from the interference with the latch 12 to move the lifting plate 11.

[0030] In addition, if Figure 8 As shown, when the user moves the lifting plate 11 upward, it takes a long time to pull the horizontal plate 14, which is quite laborious. In order to simplify the movement of the lifting plate 11 upward, this embodiment further includes a rotating assembly, wherein the rotating assembly includes a bearing plate 18 and a top rod 19. The rotating assembly is described in detail below: The load-bearing plate 18 is fixed to the outer side of the connecting plate 5, and the push rod 19 is fixed to the top of the load-bearing plate 18, and the push rod 19 passes through the lifting plate 11. The diameter of the push rod 19 at the top of the lifting plate 11 is larger than the diameter of the push rod 19 inside the lifting plate 11. In the initial state, the latch 12 and the card plate 13 are in the same plane. When the lifting plate 11 needs to be moved up, it is only necessary to drive the lifting plate 11 to rotate along the outer side of the push rod 19. After the lifting plate 11 rotates, the latch 12 is not in the same plane. At this time, when the lifting plate 11 moves up, the latch 12 will not be blocked by the card plate 13.

[0031] Further, such as Figure 9 and Figure 10As shown, a spur gear 20 is fixed to the outer side of the connecting rod 4. When the connecting rod 4 moves up, the spur gear 20 will be driven to move up. A rack 21 is provided on the periphery of the spur gear 20. The outer side of the rack 21 is connected to a fixed rod 22. When the spur gear 20 moves up, it will contact with the rack 21 and rotate. The rotation of the spur gear 20 will drive the connecting rod 4 to rotate, and the rotation of the connecting rod 4 will drive the conical barrel cover 3 to rotate. It should be noted that the length of the rack 21 is designed to ensure that when the spur gear 20 moves from the bottom end of the rack 21 to disengage from the meshing with the rack 21, the spur gear 20 rotates 180°, and the conical barrel cover 3 also rotates 180°, aligning the wide mouth of the guide groove 10 with the water outlet 2. Through the above-mentioned structural design, it is achieved that the conical barrel cover 3 automatically rotates 180° when it moves up, avoiding the staff from moving the cone upward. When the conical barrel cover 3 is formed, it is also necessary to rotate the conical barrel cover 3, which improves the convenience of using the device. The end of the fixing rod 22 away from the rack 21 is fixedly connected to a guide plate 23, and a pair of limiting rods 24 are slidably connected inside the guide plate 23. Both ends of the pair of limiting rods 24 are fixedly connected to a top plate 25, and the top plate 25 is connected to the top of the barrel body 1. When the spur gear 20 moves up and disengages from the meshing with the rack 21, the staff pushes the rack 21 toward the water outlet 2. It should be noted that the through hole 29 provided at the top of the cover shell 28 can provide space for the staff to reach into the interior of the cover shell 28 and push the rack 21. At this time, the spur gear 20 will not mesh with the rack 21 when it moves down, thereby ensuring that the conical barrel cover 3 after rotation can fit the wide mouth of the guide groove 10 into the water outlet 2 (such as Figure 5 As shown in the figure, by designing the movable rack 21, it is more labor-saving and convenient than the staff manually lifting the conical barrel cover 3 while rotating the conical barrel cover 3. Directly rotating the conical barrel cover 3 also needs to withstand the elastic potential energy from the spring 9, while directly moving the rack 21 is simpler and more labor-saving, and there is no need to apply additional rotational force to the conical barrel cover 3.

[0032] In addition, if Figure 4 and Figure 5 As shown, a pair of pull rings 26 are rotatably connected to the outer side of the connecting rod 4. The pull rings 26 are constructed of a hollow tube and a pair of square plates. The design of the pull rings 26 can facilitate the staff to pull up the connecting rod 4.

[0033] In addition, if Figure 1 and Figure 11 As shown, a pair of cover shells 28 are fixedly connected to the outside of the barrel body 1, and a pair of through holes 29 are opened at the top of the pair of cover shells 28. The cover shells 28 can protect the components on the outside of the barrel body 1, avoid accidental touch and play a dust-proof role, and the setting of the pair of through holes 29 can facilitate the user to operate the pull ring 26, rotate the lifting plate 11 and move the rack 21.

[0034] As an implementation method, Figure 1-Figure 5 As shown, the present application provides a HDPE ultra-clean barrel, comprising a barrel body 1, a water outlet 2, a conical barrel cover 3, two connecting rods 4, an elastic pulling mechanism, a liquid collecting mechanism and a carrying plate 27, wherein the water outlet 2 is installed at the top of the barrel body 1, and the water outlet 2 and the interior of the barrel body 1 are mutually connected. The through-connection design can ensure that the liquid inside the barrel body 1 can be discharged through the water outlet 2, and the water outlet 2 and the conical barrel cover 3 are mutually in contact with each other to play a sealing role. The two connecting rods 4 are fixedly connected to the outer side of the conical barrel cover 3, and the connecting rods 4 are connected to the outer side of the conical barrel cover 3. The conical barrel cover 3 plays a supporting role. The elastic pulling mechanism is sleeved on the outside of the connecting rod 4 and is used to pull the connecting rod 4 downward so that the conical barrel cover 3 is tightly fitted with the water outlet 2. The liquid collecting mechanism is arranged inside the conical barrel cover 3 and is used to collect and flow out the liquid inside the barrel body 1 when the conical barrel cover 3 is inverted on the outside of the water outlet 2. The carrying plate 27 is fixed to the top of the barrel body 1 and is used to lift the barrel body 1. The design of the carrying plate 27 is more in line with human mechanics, making it easier to lift the barrel body 1 and more convenient for the staff to move the position of the barrel body 1.

[0035] When the bottle cap 3 is in the closed position, the bottle cap 3 is in the closed position, and the bottle cap 3 is in the closed position, so that the bottle cap 3 is in the closed position and the bottle cap 3 is in the closed position. When the connecting rod 4 moves up, it drives the spur gear 20 to move up, and when the spur gear 20 moves up, it contacts the rack 21 and rotates. The rotation of the spur gear 20 drives the connecting rod 4 to rotate, and the rotation of the connecting rod 4 drives the conical barrel cover 3 to rotate. At this time, the conical barrel cover 3 aligns the wide mouth of the guide groove 10 with the water outlet 2. When the spur gear 20 moves up and disengages from the meshing with the rack 21, the staff pushes the rack 21 toward the water outlet 2. At this time, when the spur gear 20 moves down, it will not mesh with the rack 21. When the conical barrel cover 3 moves down and resets to fit the water outlet 2, the guide groove 10 will be in close contact with the outer side of the water outlet 2 to achieve a certain sealing effect. Subsequently, when the internal liquid of the barrel body 1 is poured out, the liquid in the guide groove 10 follows the width and narrow design of the guide groove 10, and the flow rate is reduced from a large flow rate, thereby increasing the pressure of the liquid flow, so that the liquid flows to the designated position. When the lifting plate 11 drives the tooth 12 to move up, the plane of the tooth 12 will be blocked by the card plate 13 and cannot move, thereby playing the role of limiting.

[0036] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
