Bucket lid opening and closing device

Abstract

The invention discloses a bucket lid opening and closing device, which comprises at least two tooth prying rods for correspondingly clamping a plurality of teeth arranged on a bucket lid to drive thebucket lid to be screwed or loosened relative to a bucket body, a driving disc for driving rotation of the tooth prying rods, a handle which is fixed relative to the driving disc and pries the drivingdisk to drive the bucket lid to rotate relative to the bucket body when the tooth prying rods clamps the corresponding teeth, wherein the driving disc is provided with a plurality of adjusting grooves, through which the at least two tooth prying rods passes so as to be driven to approach or leave the corresponding teeth in a radial direction during rotating, and the handle is provided with a locking block capable of abutting against the driving disc to limit the driving disc to rotate relative to the bucket lid. When the bucket lid is opened or closed, the driving disc is firstly rotated, theadjusting grooves drive the tooth prying rods to clamp the corresponding teeth in a radial direction, then the locking block is started for locking the driving disc, and finally the handle is pried,so that the bucket lid rotates along with the handle and relative to the bucket body and is screwed or loosened. Since the handle can save labor, reduction of the difficulty of opening and closing thebucket lid is facilitated.

Description

technical field [0001] The invention relates to the field of living appliances, in particular to a bucket lid opening and closing device. Background technique [0002] The barrel body and the lid of the barrel with lid cooperate with each other to form a closed cavity with a certain storage space, which is convenient for storing liquid or solid substances. It has the advantages of good sealing and easy transportation, and is widely used in various fields. [0003] However, since the bung of the existing bucket with a lid is usually fixedly connected with the bucket body through threaded connection or the like, it is difficult to open the bung. [0004] Take the plastic bucket containing the pre-painting agent as an example. The lid of the plastic bucket is made of high-strength plastic resistant to strong acids and alkalis, and the lid and the barrel are connected by threads. In order to ensure that the bucket with the lid has a good Sealing, the lid and the barrel must hav...

AI Technical Summary

Problems solved by technology

When using the pre-painting agent, due to the high connection strength between the lid and the barrel body, it is usually impossible to unscrew the lid with bare hands. The operator generally needs to use paper knives, scissors, screwdrivers and other tools to repeatedly violently pry open or Cutting off the lid makes opening the lid time-consuming and laborious, and there are certain safety hazards

[0005] Therefore, it is relatively difficult to open and close the bung with a lid opening.
