Description

Technical Field

[0001] The utility model relates to the technical field of manual tools, and more specifically to a wrench for the lid of a plastic chemical barrel. Background Art

[0002] In chemical enterprises, plastic chemical barrels with a capacity of more than 120L are commonly used for filling, and the lids used for them mostly adopt cross grooves for tightening and loosening. During workshop use, to prevent liquid leakage caused by the lid not being tightened firmly, the lid is often tightened too tightly. However, since most existing wrenches are flat wrenches, the two horizontal contact points bear too much force, resulting in damage to the lid grooves. In severe cases, the grooves are completely damaged, and the lid can only be opened by destructive means.

[0003] Patent CN212101934U discloses a lid wrench, which includes a fixator and a rotator fixedly arranged on the fixator. The fixator is set as a circular ring structure, and a plurality of tooth-shaped structures are arranged on the inner wall of the circular ring structure. Tooth-shaped protrusions are arranged on the outer peripheral edge of the lid. The tooth-shaped structures on the inner wall of the fixator cooperate with the tooth-shaped protrusions on the outer peripheral edge of the lid to clamp the fixator and the lid together, so that the fixator and the lid cannot rotate relative to each other. The rotator is fixed on the fixator. By holding the rotator and rotating it, the fixator and the lid can be driven to rotate together. During this process, without removing the lid wrench, the lid can be tightened or loosened at one time, which is time-saving and labor-saving. In this way, the problem of time-consuming and laborious operation when using the existing wrench tool to tighten the lid, that is, aligning the wrench tool with the lid and rotating it half a circle, removing the wrench, aligning the wrench tool with the lid and continuing to rotate, and so on in a cycle, is solved. Although this application solves the problem of saving time and labor, it requires the tooth-shaped structure of the wrench to cooperate with the tooth-shaped protrusions on the outer peripheral edge of the lid to achieve rotation. Such a tool requires a fixed lid to cooperate. If a lid with an inner groove needs to be opened, since there are no tooth-shaped protrusions on the outer edge of the lid, this structure is not applicable. Therefore, a new type of lid wrench is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a wrench for the lid of a plastic chemical barrel, which is used to solve the problems that the lid is difficult to open and the lid is easily damaged when using tools in the prior art.

[0005] The technical solution of the utility model:

[0006] The utility model provides a wrench for the lid of a plastic chemical barrel, which includes a fixator 3, a fixing rod 2, a rotating rod 1, and a fixator protrusion 4. The fixing rod 2 is arranged above the fixator 3 and fixed by welding. A rotating rod 1 is arranged at the upper end of the fixing rod 2. The rotating rod 1 passes through the hole at the upper end of the fixing rod 2 and is fixedly connected by a pin, and is symmetric left and right. The fixator 3 is set as a cross structure.

[0007] The two ends of the cross-shaped fixer are provided with fixer protrusions.

[0008] The fixer protrusion 4 is in a "convex" shape.

[0009] The materials of the fixer (1), the fixing rod (2) and the rotating rod (3) are all copper.

[0010] The beneficial technical effects of the present utility model are as follows: The fixer is set in a cross-shaped structure, which is used in cooperation with the cross-shaped groove of the plastic chemical barrel. By rotating the rotating rod, the barrel cover can be smoothly opened or the barrel cover can be tightly suspended. The front end of the fixer is provided with a fixer protrusion, which can increase the contact points with the barrel cover and reduce the problem of barrel cover breakage caused by two-point contact in the past. In addition, since some chemical barrels are provided with a ventilation cover in addition to the cross-shaped groove, when opening the barrel, the ventilation cover also needs to be opened. The front protrusion of the fixer protrusion can vertically enter the ventilation cover, and by rotating the fixer, the ventilation cover can be smoothly opened. This structure is simple and convenient to use. The cooperation with the barrel cover is convenient at one time. There are protrusions on both sides of the fixer (1) for tightening and loosening the ventilation cover on the barrel. By holding the rotating rod and rotating, the fixing rod, the fixer and the barrel cover can be driven to rotate together. During this process, there is no need to remove the barrel cover wrench, and the barrel cover can be tightly suspended or loosened at one time, saving time and effort. Description of the Drawings

[0018] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings. Embodiment 1
