Description

TECHNICAL FIELD

[0001] The utility model relates to chemical container technical field, specifically point to a kind of chemical barrel bucket lid not easy to break. BACKGROUND

[0002] Plastic drum has the characteristics of not easy to break, not rust, light weight, and due to the oil resistance, corrosion resistance of plastic material, so it is often used for packaging of chemical products. Plastic drum is mainly composed of barrel body and barrel cover, and barrel body and barrel cover are installed by thread connection. Usually, the barrel mouth of the barrel body is as a male end, and the barrel cover is as a female end and is connected by thread. For example, a plastic drum disclosed in Chinese patent CN220164740U includes a barrel body and a barrel cover, the barrel cover is arranged on the barrel body, and the barrel body is provided with external threads. The barrel cover is provided with internal threads. The barrel body and the barrel cover are connected by the cooperation of the external threads and the internal threads. Although the above-mentioned prior art is convenient for manual tightening and opening, the sealing between the barrel cover and the barrel mouth is not strong due to the small end area of the barrel mouth, and a sealing gasket is usually arranged between the barrel cover and the barrel mouth to prevent leakage.

[0003] There are also embedded barrel covers on the market, that is, the barrel cover is provided with external threads as a male end, and the barrel mouth is provided with internal threads as a female end, and the barrel cover can be embedded in the barrel mouth. The barrel cover is provided with a cover face to block the end face of the barrel mouth, and the contact area between the barrel cover and the barrel mouth is increased to improve the sealing. Since the barrel cover of the plastic drum is usually hollow, that is, the insertion end of the barrel cover is a hollow pipe structure, and the connection strength between the barrel cover and the barrel mouth is determined by the length of the insertion end. A too long insertion end will reduce its own rigidity, so that in the case of tight rotation of the barrel cover and the barrel mouth, the strength of the insertion end is not enough to withstand the rotation torque, resulting in deformation, and in severe cases, the barrel cover will be directly broken in the barrel mouth, which seriously affects the use of the plastic drum.

[0004] Therefore, the prior art still needs to be improved and developed. UTILITY MODEL CONTENTS

[0005] The utility model aims at the defects and deficiencies of the prior art, and provides a chemical barrel bucket lid which is reasonable in structure, high in strength and stable and not easy to break.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] The utility model discloses a chemical barrel bucket lid not easy to break, which comprises a cover body, a hollow threaded end is arranged on the bottom surface of the cover body, and external threads are arranged on the outer side wall of the threaded end.

[0008] According to the above scheme, a receiving groove is provided on the upper surface of the cover.

[0009] According to the above scheme, the receiving slot is used to adapt to the unlocking tools, and the unlocking tools adapted to the receiving slot include cross keys, hexagonal keys and Phillips keys.

[0010] According to the above scheme, the receiving groove is recessed downward into the inner cavity of the threaded end, and the edge of the receiving groove abuts against the inner sidewall of the threaded end.

[0011] According to the above scheme, on the bottom surface of the receiving groove Provided are Ventilation holes.

[0012] According to the above scheme, a fixing sleeve is provided on the bottom surface of the receiving groove, and the vent hole is matched with the fixing sleeve.

[0013] The beneficial effects of this utility model are as follows: This utility model has a reasonable structure. The threaded end is connected to the barrel opening through the thread on its outer side. Several reinforcing ribs can strengthen the structural strength of the threaded end. At the same time, the reinforcing ribs are set along the length direction of the threaded end, so that the length of the threaded end can be made longer, thereby improving the connection strength between the cover and the chemical barrel. Attached Figure Description

[0014] Fig. 1 This is a top view of the overall structure of this utility model;

[0015] Fig. 2 This is a schematic diagram of the overall structure of this utility model from a bottom-view perspective.

[0016] In the picture:

[0017] 1. Cover; 2. Threaded end; 11. Receiving groove; 12. Vent hole; 13. Fixing sleeve; 21. Reinforcing rib. Detailed Implementation

[0018] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0019] like Figs. 1-2 As shown, the present invention provides a chemical drum lid that is not easily broken, comprising a lid body 1. The bottom surface of the lid body 1 has a hollow threaded end 2, and the outer wall of the threaded end 2 has external threads. The threaded end 2 has several reinforcing ribs 21, which are equidistantly spaced on the inner wall of the threaded end 2 and extend along the length of the threaded end 2. The threaded end 2 is used to insert into the drum opening and connects to the chemical drum through the external threads on its outer wall. The reinforcing ribs 21 enhance the structural strength of the threaded end 2, and their extension along the length of the threaded end 2 allows for a longer threaded end 2, thereby increasing the connection strength between the lid body 1 and the chemical drum.

[0020] The upper end surface of the cover 1 is provided with a receiving groove 11, and the cover 1 is connected to the chemical barrel by screwing the threaded end 2. Because the length of the threaded end 2 is longer, the threaded connection strength between the threaded end 2 and the chemical barrel is higher, and the threaded end 2 needs a larger screwing torque. Further, the receiving groove 11 is used to adapt to a unlocking tool, and the unlocking tool adapted to the receiving groove 11 includes a cross lock pick, an internal hexagonal lock pick and a keyhole lock pick. By matching the receiving groove 11 with the unlocking tool, the cover 1 can be better tightened, the connection strength between the cover 1 and the chemical barrel is improved, and of course the sealing performance is also improved. Conversely, the unlocking tool can also be more easily loosened from the cover 1 through the receiving groove 11.

[0021] The receiving groove 11 is recessed downward into the inner cavity of the threaded end 2, and the edge of the receiving groove 11 abuts against the inner side wall of the threaded end 2. The cover 1 and the threaded end 2 are preferably integrally formed of a plastic structure, so that the receiving groove 11 is embedded in the threaded end 2 as a countersunk groove, which can reduce the thickness of the cover 1, thereby reducing the protruding height of the cover 1 when mounted on the chemical barrel.

[0022] It can be understood that in some chemical barrel products, some chemical materials change in internal pressure during storage. The bottom surface of the receiving groove 11 is provided with a breathable hole 12, which can communicate the inside of the chemical barrel with the outside, but the breathable hole 12 is arranged in the receiving groove 11, and the chemical raw materials will not splash out through the breathable hole 12.

[0023] Further, the bottom surface of the receiving groove 11 is provided with a fixing sleeve 13, and the breathable hole 12 and the fixing sleeve 13 are arranged in pairs. The fixing sleeve 13 is used to arrange a valve core structure, which can prevent external water, dust and other impurities from entering the chemical barrel while ensuring breathability, thereby ensuring the purity of the stored materials.

[0024] The above only describes the preferred embodiments of the present application, and any equivalent changes or modifications made in accordance with the structure, features and principles of the present application patent application range are included in the present application patent application range.
