Description

Technical Field

[0001] The utility model relates to the technical field of plastic barrel covers, in particular to a plastic barrel cover with a quick-opening structure. Background Art

[0002] Plastic barrels are mostly made of polyethylene, polypropylene and other plastics through blow molding and injection molding. They are the outer packaging of liquids and solid products in the chemical, pesticide, pharmaceutical, food, hardware and electronics, electromechanical and other industries. The lids of common plastic barrels on the market are mostly composed of a plastic barrel outer lid and a sealed inner lid. When closing the plastic barrel, you need to first insert the sealed inner lid into the mouth of the plastic barrel, and then screw the plastic barrel lid on the mouth of the plastic barrel to ensure the internal sealing of the plastic barrel. However, when you need to open the plastic barrel, you need to first unscrew the plastic barrel lid, and then pull off the sealed inner lid, which will reduce the convenience of opening and closing the plastic barrel. In view of the above situation, technical innovation is carried out on the basis of the existing plastic barrel lid with a quick opening structure. Utility Model Content

[0003] The utility model aims to provide a plastic bucket cover with a quick opening structure to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a plastic barrel cover with a quick opening structure, comprising:

[0005] A plastic barrel cover, wherein a sleeve is provided inside the plastic barrel cover, wherein:

[0006] A spring is arranged at the top of the inner wall of the sleeve, a connecting column is arranged at the bottom of the spring, and the connecting column is arranged in the inner cavity of the sleeve;

[0007] The sealing inner cover, the bottom of the connecting column is arranged at the bottom of the inner side wall of the sealing inner cover.

[0008] Preferably, a handle is provided on the top of the plastic barrel cover, and the sealed inner cover is located below the plastic barrel cover.

[0009] Preferably, a groove is provided at the top of the inner side wall of the plastic barrel cover, and a bearing is arranged in the groove.

[0010] Preferably, the top of the sleeve is arranged inside the bearing, and the outer side wall of the plastic barrel cover is evenly provided with anti-slip patterns.

[0011] Preferably, a group of slide grooves are provided on both left and right sides of the inner side wall of the sleeve, and a group of guide blocks are provided on both left and right sides of the connecting column, and the guide blocks are arranged in the slide grooves.

[0012] Preferably, the bottom of the sleeve is flush with the bottom of the plastic barrel cover, and the bottom of the bearing is flush with the top of the inner side wall of the plastic barrel cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model places the sealing inner cover on the barrel mouth of the plastic barrel, then presses down and rotates the handle, thereby driving the plastic barrel cover to rotate and be screwed and fixed on the outer side of the barrel mouth of the plastic barrel. During the process of tightening the plastic barrel cover, the plastic barrel cover moves downward, and the spring pushes the connecting column downward by its own resilience, thereby driving the sealing inner cover to be inserted into the barrel mouth of the plastic barrel, so that the plastic barrel cover and the sealing inner cover can be quickly installed, thereby improving the convenience of using the plastic barrel.

[0015] When the handle is turned in the opposite direction and pulled upward, the plastic barrel cover can be unscrewed from the plastic barrel. When the plastic barrel cover is unscrewed, continue to pull the handle upward to pull the sealed inner cover off the plastic barrel, thereby achieving the effect of quickly opening the plastic barrel.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 3A plastic barrel cover with a quick opening structure comprises a plastic barrel cover 1 and a sealed inner cover 12. A sleeve 14 is rotatably arranged inside the plastic barrel cover 1. A spring 16 is fixedly arranged on the top of the inner wall of the sleeve 14. A connecting column 13 is fixedly arranged on the bottom of the spring 16. The connecting column 13 is slidably arranged in the inner cavity of the sleeve 14. The bottom of the connecting column 13 is fixedly arranged on the bottom of the inner wall of the sealed inner cover 12. A handle 11 is fixedly arranged on the top of the plastic barrel cover 1. The sealed inner cover 12 is located below the plastic barrel cover 1. A groove is provided on the top of the inner wall of the plastic barrel cover 1. A bearing 15 is fixedly arranged in the groove. The top of the sleeve 14 is fixedly arranged inside the bearing 15. When the plastic barrel cover 1 rotates, the bearing 15 can prevent the plastic barrel cover 1 from driving the sealed inner cover 12 to rotate. The sealed inner cover 12 is placed on the barrel mouth of the plastic barrel, and then the handle 11 is pressed down and rotated to drive the plastic barrel cover 1 to rotate. When the plastic barrel cover 1 rotates, it will be screwed and fixed on the outer side of the barrel mouth of the plastic barrel. , during the tightening process of the plastic barrel cover 1, it will move downward, and the spring 16 will resist the connecting column 13 to move downward through its own resilience, thereby driving the sealed inner cover 12 to be inserted into the barrel mouth of the plastic barrel, so that the plastic barrel cover 1 and the sealed inner cover 12 can be quickly installed. When the handle 11 is rotated in the opposite direction and the handle 11 is pulled upward, the plastic barrel cover 1 can be unscrewed from the plastic barrel. When the plastic barrel cover 1 is unscrewed, the handle 11 is continued to be pulled upward, and the sealed inner cover 12 can be pulled off the plastic barrel, so as to achieve the effect of quickly opening the plastic barrel. The outer wall of the plastic barrel cover 1 is evenly provided with anti-slip grooves, and a group of slide grooves are provided on the left and right sides of the inner wall of the sleeve 14. A group of guide blocks 17 are fixedly provided on the left and right sides of the connecting column 13. The guide blocks 17 are slidably arranged in the slide grooves, and the connecting column 13 is assisted by the guide blocks 17 to move up and down stably. The bottom of the sleeve 14 is flush with the bottom of the plastic barrel cover 1, and the bottom of the bearing 15 is flush with the top of the inner wall of the plastic barrel cover 1.

[0022] Working principle: Place the sealed inner cover 12 on the mouth of the plastic barrel, then press down and turn the handle 11 to drive the plastic barrel cover 1 to rotate. When the plastic barrel cover 1 rotates, it will be screwed and fixed on the outside of the mouth of the plastic barrel. During the tightening process of the plastic barrel cover 1, it will move downward. The spring 16 will use its own rebound force to push the connecting column 13 downward, thereby driving the sealed inner cover 12 to be inserted into the mouth of the plastic barrel, so that the plastic barrel cover 1 and the sealed inner cover 12 can be quickly installed. When the handle 11 is turned in the opposite direction and pulled upward, the plastic barrel cover 1 can be unscrewed from the plastic barrel. When the plastic barrel cover 1 is unscrewed, continue to pull the handle 11 upward to pull the sealed inner cover 12 off the plastic barrel, thereby achieving the effect of quickly opening the plastic barrel.
