Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic barrels, in particular to a plastic barrel with high sealing performance. Background Art
[0002] Plastic barrels are mostly made of polyethylene, polypropylene and other plastics by blow molding and injection molding. Plastic barrels are mostly used for the storage and transportation of various liquids. They have good properties for special dangerous goods packaging. They are not easy to break, rust-proof, lightweight, and have excellent oil and strong corrosion resistance. They are mostly used for dangerous goods packaging that requires heat preservation, moisture resistance, pressure resistance, and corrosion resistance.
[0003] However, existing plastic barrels still have some shortcomings in actual use: the existing sealing structure is often relatively simple, usually relying on a single snap or simple threaded connection. This simple connection method cannot effectively deal with the problem of sealing failure caused by external factors during long-term use. During transportation, vibrations and external force impacts such as vehicle bumps, mutual squeezing and collision of goods, and collisions during loading and unloading frequently occur. These external forces can easily loosen the original connection between the barrel cover and the barrel body, thereby destroying the sealing effect and causing liquid leakage or gas escape in the barrel.
[0004] To this end, we designed a highly sealed plastic barrel to solve the above problems. Utility Model Content
[0005] The purpose of the present invention is to provide a plastic barrel with high sealing performance to solve the problems raised in the above background technology.
[0006] In order to solve the above technical problems, the utility model provides a highly sealed plastic barrel, including a barrel body and a barrel cover, wherein an insertion strip is fixedly connected to the barrel cover, a slot is provided at the top of the barrel body, a compression spring is fixedly connected to the bottom end of the slot, the insertion strip is slidably inserted into the slot, and the bottom end of the insertion strip is abutted against the top end of the compression spring, mounting seats are fixedly connected on both sides of the barrel cover, a socket is provided in the mounting seat, a buckle assembly is rotatably connected in the socket, hooks are fixedly connected to both sides of the barrel body, and the buckle assembly is overlapped in the hooks.
[0007] Furthermore, the snap-fit assembly includes a pin shaft, which is rotatably connected in the socket, and a connecting plate is provided on the pin shaft. Slide grooves are provided at both ends of the connecting plate, and the pin shaft is rotatably connected in the slide groove. The other end of the connecting plate is fixedly connected to a circular shaft, and both ends of the circular shaft are rotatably connected to a rotating shaft, and the end of the rotating shaft away from the connecting plate is fixedly connected to a card frame.
[0008] Furthermore, an elastic member is fixedly connected to the inside of the card frame, the hook is in a U-shape, and the card frame can be overlapped in the hook.
[0009] Furthermore, the bottom end of the pin is fixedly connected to a return spring, and the bottom end of the return spring is fixedly connected to the rotating shaft.
[0010] Furthermore, there are two return springs, and the two return springs are fixedly connected to both ends of the pin shaft respectively.
[0011] Furthermore, an inner lining cover is fixedly connected to the inside of the barrel cover, the size of the inner lining cover matches the opening at the top of the barrel body, and a sealing ring is fixedly connected to the side of the inner lining cover.
[0012] Furthermore, handles are fixedly connected to both sides of the barrel body, and the handles are provided with anti-slip patterns.
[0013] Furthermore, a non-slip shock-absorbing pad is fixedly connected to the bottom end of the barrel body, and the material of the non-slip shock-absorbing pad is rubber.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] In the utility model, the insert strip in the barrel cover cooperates with the compression spring in the card slot at the top end of the barrel body. After the buckling assembly is clamped and fixed with the hook, the compression spring further enhances the tightness of the connection between the barrel cover and the barrel body. The elastic member in the card frame increases the contact area and friction with the hook. In addition, the two return springs at the bottom end of the pin shaft work together to make the connection between the buckling assembly and the hook more stable. When the device encounters external forces such as vibration and impact during use, the compression spring in the card slot and the return spring on the buckling assembly will generate upward elastic force, so that the buckling assembly and the hook are firmly clamped, which can effectively resist the influence of external forces such as vibration and impact, so that the plastic barrel can remain sealed for a long time. At the same time, the inner lining cover in the barrel cover and the sealing ring on its side are squeezed during the process of fixing the barrel cover to the barrel body, which effectively fills the gap and prevents liquid or gas leakage, and can meet storage and transportation requirements with high requirements for sealing.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 efforts are within the scope of protection of the present invention.
[0022] See also Figure 2 and Figure 3 The utility model provides a technical solution: a highly sealed plastic barrel, comprising a barrel body 1 and a barrel cover 2, an inserting strip 3 is fixedly connected inside the barrel cover 2, a card slot 4 for inserting the inserting strip 3 is opened at the top of the barrel body 1, a compression spring 5 is fixedly connected to the bottom end of the card slot 4, the inserting strip 3 is slidably inserted into the card slot 4, and the bottom end of the inserting strip 3 is against the top end of the compression spring 5, mounting seats 6 are fixedly connected on both sides of the barrel cover 2, a plug hole 7 is opened in the mounting seat 6, a buckle assembly 8 is arranged in the plug hole 7, hooks 9 are fixedly connected on both sides of the barrel body 1, and the buckle assembly 8 is overlapped in the hooks 9.
[0023] During specific implementation, when sealing the plastic barrel, the barrel cover 2 is placed on the barrel body 1, and the insertion strip 3 in the barrel cover 2 is inserted into the slot 4 at the top of the barrel body 1. As the insertion action occurs, the insertion strip 3 compresses the compression spring 5 in the slot 4. At the same time, the snap-fit assembly 8 in the mounting seat 6 on both sides of the barrel cover 2 can be rotated and overlapped on the hooks 9 on both sides of the barrel body 1, thereby preliminarily fixing the barrel cover 2 and the barrel body 1. The compression spring 5 will generate a reaction force during the compression process, which helps to tightly combine the barrel cover 2 and the barrel body 1.
[0024] See Figure 1 and Figure 4 The snap-fit assembly 8 includes a pin 81, which is rotatably connected to the socket 7. A connecting plate 82 is provided on the pin 81. Slide grooves 83 are provided at both ends of the connecting plate 82. The pin 81 is rotatably connected in the slide groove 83. The other end of the connecting plate 82 is fixedly connected to a circular shaft 84. Both ends of the circular shaft 84 are rotatably connected to a rotating shaft 85. The end of the rotating shaft 85 away from the connecting plate 82 is fixedly connected to a card frame 86.
[0025] During specific implementation, the pin 81 in the buckle assembly 8 rotates in the socket 7. When the buckle is operated, the connecting plate 82 is pulled. Since the pin 81 rotates in the slide groove 83 of the connecting plate 82, the connecting plate 82 can move relative to the pin 81, driving the circular shaft 84 to move. The rotating shafts 85 at both ends of the circular shaft 84 and the card frame 86 fixed on the rotating shaft 85 move accordingly, so as to engage or disengage with the hook 9.
[0026] See Figure 4 An elastic member 87 is fixedly connected to the card frame 86 , and the hook 9 is U-shaped. The card frame 86 can be overlapped in the hook 9 .
[0027] In specific implementation, when the card frame 86 is engaged with the hook 9, the elastic member 87 in the card frame 86 will contact the U-shaped hook 9. When subjected to external force, the elastic member 87 will deform, filling the tiny gap between the card frame 86 and the hook 9, increasing the contact area and friction between the two, so that the card frame 86 is more firmly stuck in the hook 9.
[0028] See Figure 4 The bottom end of the pin 81 is fixedly connected to a return spring 88 , and the bottom end of the return spring 88 is fixedly connected to the rotating shaft 85 .
[0029] In specific implementation, when operating the snap-fit assembly 8, the connecting plate 82 is pulled downward, and the return spring 88 at the bottom end of the pin shaft 81 is stretched. When the card frame 86 is inserted into the hook 9, the return spring 88 is in a stretched state, and the elastic force generated by it acts on the rotating shaft 85, so that the card frame 86 has a force in the direction of approaching the hook 9, further enhancing the connection tightness between the card frame 86 and the hook 9.
[0030] See Figure 4 There are two return springs 88 , and the two return springs 88 are fixedly connected to both ends of the pin shaft 81 respectively.
[0031] In specific implementation, the two return springs 88 are respectively fixed at the two ends of the pin shaft 81. When the snap-fit assembly 8 is operated, the return springs 88 at both ends are stretched at the same time. After the card frame 86 is snapped with the hook 9, the elastic force generated by the return springs 88 at both ends can act more evenly on the snap-fit assembly 8, making the connection between the card frame 86 and the hook 9 more stable and uniformly stressed.
[0032] See Figure 2 The inside of the barrel cover 2 is fixedly connected with an inner lining cover 10, the size of the inner lining cover 10 is consistent with the opening at the top of the barrel body 1, and the side of the inner lining cover 10 is fixedly connected with a sealing ring 11.
[0033] In specific implementation, when the barrel cover 2 is covered on the barrel body 1, the inner lining cover 10 inside the barrel cover 2 coincides with the top opening of the barrel body 1, and the sealing ring 11 is made of elastic rubber material. The sealing ring 11 on its side is in close contact with the inner wall of the barrel body 1. In the process of fixing the barrel cover 2 and the barrel body 1 by the structures such as the insertion strip 3, compression spring 5, buckle assembly 8 and hook 9, the sealing ring 11 is squeezed to fill the gap between the barrel cover 2 and the barrel body 1 to form a seal.
[0034] See Figure 1 , handles 12 are fixedly connected to both sides of the barrel body 1, and the handles 12 are provided with anti-slip lines.
[0035] In specific implementation, when using the plastic bucket, the user can hold the handles 12 on both sides of the bucket body 1 for carrying and other operations. The anti-slip patterns on the handles 12 increase the friction between the hands and the handles 12, allowing the user to grip more stably.
[0036] See Figure 1 The bottom end of the barrel body 1 is fixedly connected with an anti-skid shock-absorbing pad, which is made of rubber.
[0037] In specific implementation, when the plastic barrel is placed on a flat surface such as the ground, the rubber anti-slip shock-absorbing pad at the bottom of the barrel body 1 contacts the contact surface. The elasticity and friction properties of the rubber make the plastic barrel more stable when placed, not easy to slide, and can cushion the impact force on the barrel body 1.
[0038] Working principle: When sealing a plastic barrel, put the barrel cover 2 on the barrel body 1, and insert the insert strip 3 in the barrel cover 2 into the card slot 4 at the top of the barrel body 1. As the inserting action occurs, the insert strip 3 compresses the compression spring 5 in the card slot 4. At the same time, the buckle assembly 8 in the mounting seat 6 on both sides of the barrel cover 2 can be rotated and overlapped on the hooks 9 on both sides of the barrel body 1, thereby preliminarily fixing the barrel cover 2 and the barrel body 1, and the compression spring 5 will generate a reaction force during the compression process, which helps to tightly combine the barrel cover 2 and the barrel body 1; the sealing ring 11 on the lining cover 10 will be squeezed to fill the gap between the barrel cover 2 and the barrel body 1 to form a seal, and then the buckle assembly 8 on the barrel cover 2 is overlapped in the hook 9 on the barrel body 1. Specifically, the pin shaft 81 in the buckle assembly 8 rotates in the socket 7. When the buckle is operated, the connecting plate 82 is pulled. Since the pin shaft 81 is on the connecting plate The chute 83 of 82 rotates, so that the connecting plate 82 can move relative to the pin shaft 81, driving the circular shaft 84 to move. The rotating shafts 85 at both ends of the circular shaft 84 and the card frame 86 fixed on the rotating shaft 85 move accordingly, so as to be engaged or disengaged with the hook 9. When the snap assembly 8 is engaged with the hook 9, the return spring 88 is always in a stretched state. The elastic force generated by the stretching of the return spring 88 acts on the rotating shaft 85, so that the card frame 86 has a force in the direction of approaching the hook 9, further enhancing the connection tightness between the card frame 86 and the hook 9. When the device is used, if it encounters external forces such as vibration and impact, the compression spring 5 in the card slot 4 and the return spring 88 on the snap assembly 8 will generate an upward elastic force, so that the snap assembly 8 is firmly engaged with the hook 9, preventing the sealing of the plastic barrel from being reduced.
