Description

Technical Field

[0001] This utility model relates to the field of disassembly tools, specifically to a tool for disassembling oil drum lids. Background Technology

[0002] Liquid oils such as lubricating oil and gasoline are typically stored in oil drums for convenient transportation. To facilitate the extraction or pouring of the liquid oil from the drum, an oil hole is located at the top of the drum, and a lid is installed at this hole. The lid is threaded onto the drum; the lid has a circular structure, and two lugs (such as...) are fixed in the groove of the lid with bolts. Figure 1 (As shown).

[0003] When using liquid oil inside an oil drum, the existing technology requires removing the top cover of the drum. Because the cover is fixed to the oil hole at the top of the drum by embedded threads, it is difficult to remove. Removing the cover is time-consuming and laborious. The cover is too tightly connected to the oil drum, making it impossible to unscrew it by hand. Using tools such as pliers or hammers is also not easy to remove the cover. The cover is easily deformed and damaged by force, making it even more difficult to remove or even impossible to install and use later. Summary of the Invention

[0004] This utility model addresses the problem of difficulty in removing the lid from the top of an oil drum in the prior art by providing an oil drum lid removal tool. This tool facilitates the removal of the lid from the top of the oil drum, saving time and effort, and the lid is not easily deformed or damaged by force, ensuring that the lid can still be used normally.

[0005] To achieve the above objectives, the technical solution of this utility model is: a tool for disassembling oil drum lids, comprising a disassembly head and a crossbar assembly detachably connected to the disassembly head. The disassembly head includes a mounting plate and an inner retaining ring, an outer retaining ring, and a baffle plate disposed at the bottom of the mounting plate. The gap between the inner and outer retaining rings forms an annular groove. The baffle plate is located inside the inner retaining ring, and oblique locking blocks are offset on both sides of the baffle plate. A connector is disposed at the top of the mounting plate. The lid is disassembled by rotating the disassembly head. The baffle plate is obliquely engaged between the two rolled ears of the lid, applying a rotational force to the lid. The oblique locking blocks are engaged inside the rolled ears of the lid to prevent the baffle plate from detaching from between the two rolled ears of the lid when a rotational force is applied to the lid, thus limiting the movement of the baffle plate.

[0006] The crossbar assembly includes a force transmission rod and a handle rod detachably connected to the force transmission rod. The force transmission rod is detachably connected to the connector. The handle rod and the force transmission rod drive the disassembly head to rotate, so that the disassembly head drives the barrel cover to rotate inside the oil hole of the oil barrel, thereby realizing the disassembly of the barrel cover.

[0007] Furthermore, the diameter of the outer retaining ring is larger than that of the inner retaining ring, and the outer diameter of the outer retaining ring is larger than that of the mounting plate, so as to ensure that the gap between the outer retaining ring and the inner retaining ring forms an annular groove. The disassembly head is clamped onto the bucket lid through the annular groove, and the cooperation with the bucket lid guides the rotational movement of the disassembly head.

[0008] Furthermore, the two inclined blocks are parallel to each other, and the inclined blocks are fixedly installed at the end of the baffle, with an acute angle between them. The purpose is to make the two inclined blocks respectively engage on the opposite sides of the two rolled ears of the bucket lid, ensuring that the inclined blocks limit the position of the baffle.

[0009] Furthermore, the connector includes a fixing plate and a threaded cylinder horizontally disposed on the top of the fixing plate. The fixing plate is bolted to the top of the mounting plate, and the threaded cylinder is fixed to the top of the mounting plate by the action of the fixing plate, so that the threaded cylinder can be connected to the crossbar assembly.

[0010] Furthermore, one end of the force transmission rod is provided with a threaded portion, and the end of the threaded portion is provided with a retaining ring that is fixedly connected to the force transmission rod. The threaded portion is sleeved inside the threaded cylinder and threadedly connected to the threaded cylinder. A fastening nut for fastening the threaded cylinder is also provided on the threaded portion. The force transmission rod and the threaded cylinder are detachably connected by a thread, so as to facilitate the disassembly of the force transmission rod and the disassembly head, thereby facilitating the carrying or storage of the disassembly tool; the fastening nut serves to fasten the threaded cylinder.

[0011] Furthermore, a threaded groove is provided at the other end of the force transmission rod, and a threaded post that mates with the threaded groove is fixedly provided at one end of the handle rod. The threaded post is threadedly connected to the force transmission rod through the threaded groove, and the force transmission rod and the handle rod are detachably connected through the mating of the threaded groove and the threaded post.

[0012] Furthermore, a handle is provided at the other end of the handle rod. The handle includes a limiting ring and a rubber sleeve. Two limiting rings are spaced apart on the handle rod. The rubber sleeve is fitted on the handle rod and located between the two limiting rings. The handle facilitates the operator to rotate the disassembly head through the handle rod and the force transmission rod, improving comfort.

[0013] The beneficial effects of this utility model through the above technical solution are as follows: This utility model has a reasonable structure and good performance. It makes it easy to remove the lid from the top of the oil drum, which saves time and effort compared with the existing technology for removing the lid and improves the efficiency of removing the lid. At the same time, the lid is not easily deformed by force during the removal process, so that the lid can still be used normally after removal.

[0014] This invention involves obliquely mounting a baffle between the two rolled ears of a bucket lid. The cooperation between the baffle and the rolled ears applies a rotational force to the bucket lid, enabling the baffle to rotate the lid within the oil hole and thus facilitating lid removal. The oblique locking blocks at both ends of the baffle are respectively mounted on opposite sides of the two rolled ears of the bucket lid, and these blocks limit the baffle, preventing it from detaching from between the two rolled ears when a rotational force is applied to the lid.

[0015] This utility model uses an annular groove between the outer and inner retaining rings to secure the baffle to the lid, ensuring that the baffle can be accurately secured in the groove of the lid. The outer and inner retaining rings cooperate with the lid to guide the rotational movement of the disassembly head. Attached Figure Description

[0021] The two inclined blocks 6 are parallel to each other. The inclined blocks 6 are fixedly installed at the end of the baffle 5 and the angle between them is acute. The purpose is to make the two inclined blocks 6 respectively clamp on the opposite sides of the two rolled ears of the bucket lid, so as to ensure that the inclined blocks 6 play a limiting role on the baffle 5 and prevent the baffle 5 from detaching from the two rolled ears of the bucket lid when a rotational force is applied to the bucket lid.

[0022] The connector includes a fixing plate 8 and a threaded cylinder 7 horizontally disposed on the top of the fixing plate 8. The fixing plate 8 is bolted to the top of the mounting plate 1, and the threaded cylinder 7 is welded to the top of the fixing plate 8.
