Abstract
The utility model discloses a barrel cover. External threads are formed at the outer part of the barrel cover; a groove with internal threads is also formed on the barrel cover; two staggered semicircular plate bodies are arranged in the groove. A special tool for screwing the barrel cover comprises a sleeve and a handle fixed on the sleeve; and a semicircular body corresponding to the plate bodies of the barrel cover is arranged in the sleeve. The barrel cover can be opened by using the tool with internal threads and is screwed together with the tool after being opened. The barrel cover on the tool is required to be screwed onto a barrel when customers use the tool to open other barrel covers. Therefore, the purpose of urging the customers to screw the barrel cover immediately is achieved, so that the opportunity of polluting sands, rainwater, dust and other impurities in the barrel is reduced, and the barrel can be continuously used without being cleaned after being withdrawn.
Description
(1) technical field
The special tooling that the utility model relates to a kind of bung and bung is tightened.
(2) background technology
The bucket that the liquid or solid goods is housed of many enterprises recycles, after the bucket that is about to fill goods is delivered to the client locus, wait the client that goods is finished using after, bucket return continues to use.
Existing cover structure is simple, but can not guarantee that the client in time builds lid after opening bung, because some client uses up in the bucket behind the goods impurity such as will causing a barrel internal contamination dust, sand, rainwater of lid in time not being screwed on turning on bung.Variations such as the interior residual goods of bucket also may go bad because of unsealing, sclerosis.The bucket of therefore returning must make water or other suitable solvents clean, thereby guarantees product design.Clean the solvent that uses and often cause environmental pollution because of reclaiming.Washing bucket has also increased the cost of goods.
(3) summary of the invention
One of the purpose of this utility model has provided a kind of bung, forces the client must in time it be tightened after opening bung, prevents that goods residual in the bucket is rotten.
Another purpose of the present utility model provides the special tooling that bung is tightened, and utilizes it can easily bung be tightened the save trouble and labor.
In order to solve the problems of the technologies described above, the utility model is realized by following measure: a kind of bung, its outside is provided with outside thread, also is provided with the sunk part that has negative thread on the described bung, is provided with the staggered semi-round plate body of two height in the described sunk part.
A kind of special tooling that above-mentioned bung is tightened of being used for comprises sleeve and is fixed on handle on the sleeve, is provided with in the described sleeve and the cooresponding semicircular body of the plate body of bung.
The beneficial effects of the utility model:
1. the client must use tapped frock just can open bung, promptly is tightened on frock after bung is opened.The client wants to continue to use frock to open other bungs, the bung on the frock must be twisted back on the bucket.So just realized the purpose of urging the client in time bung to be screwed on, thereby reduced the chance of impurity such as a bucket internal contamination sand, rainwater, dust, bucket can have been cleaned after returning and continue and use.So both, also reduced and use cleaning solvent and then reduced environmental pollution for enterprise has reduced cost.
2. the utility model provides frock, utilizes it that bung is tightened, the save trouble and labor.
