Description

A kind of cover opener

Technical field

This utility model is related to liquid fertilizer packaging facilities field, more particularly, to a kind of cover opener.

Background technology

Liquid fertilizer is applied by irrigation system because it is very convenient, need not dissolve, and Root Absorption is fast, the feature of instant effect Increasingly obtain the favor of user, on market, such liquid fertilizer typically to be packed using pail pack and to transport.But packaging There are unique multiple seal points although ensure that liquid is not revealed between staving and Packing bucket bung, but when opening very not Convenient.Now with a kind of quick cover opener of utilization lever principle, but its support bar and handle by the way of hinged, at it When front gib head hooks the junction of bung and staving, also need to guarantee the position of handle, the position of gib head before holding, complex steps, And support plate is placed on bung for plate-like structure, more arduously.

Utility model content

Technical problem to be solved in the utility model is to provide laborsaving, easy to operate, simply a kind of cover opener of structure.

For solving above-mentioned technical problem, technical solution adopted in the utility model is：

A kind of cover opener it is characterised in that：Including handle, located at handle one end rise lid hook, on handle near rise The support bar of lid hook one end；Described lid hook and support bar are generally aligned in the same plane；Described lid hook bending is to the handle other end；Institute State lid hook front end and be provided with projection；Described support bar is bending-type, and its wrap direction is contrary with the wrap direction playing lid hook.

Technical scheme is further：Described handle is 75 °～85 ° with the angle α playing lid hook.

Technical scheme is further：It is provided with backing plate below described support bar.

Technical scheme is further：Described backing plate upper surface becomes obtuse angle with the angle playing lid hook extended line.

Have the beneficial effects that using produced by technique scheme：

Easy to operate using this utility model, only need to will play the projection of lid hook front end and the junction pair of bung and staving Together, exert a force downwards, simple to operate；Handle and the angle α playing lid hook are 75 °～85 ° this angular range forces is to save most Power；When being disposed to prevent operation of backing plate, support bar causes the damage of bung in the presence of downward power；On backing plate Surface becomes obtuse angle with the angle playing lid hook extended line, is in order in operation, backing plate is gradually added with the contact area of bung Greatly, center of gravity is moved back by, and reduces the backing plate pressure downward to bung.

Brief description

With reference to the accompanying drawings and detailed description this utility model is described in further detail.

Fig. 1 is structural representation of the present utility model.

Wherein：Gib head, 3- support bar, 4- backing plate before 1- handle, 2-.

Specific embodiment

With reference to the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly Chu, it is fully described by it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.

Elaborate a lot of details in the following description in order to fully understand this utility model, but this practicality is new Type can also be different from alternate manner described here to implement using other, and those skilled in the art can be without prejudice to this reality With doing similar popularization in the case of new intension, therefore this utility model is not limited by following public specific embodiment.

A kind of cover opener according to Fig. 1, including handle 1, playing lid hook 2, leaning on handle 1 located at handle 1 one end Closely play the support bar 3 of lid hook 2 one end；Described lid hook 2 and support bar 3 are generally aligned in the same plane；The bending of described lid hook 2 is to handle 1 other end；Described lid hook 2 front end is provided with projection；Described support bar 3 is bending-type, the bending of its wrap direction and a lid hook 2 In opposite direction.

Using the cover opener in the present embodiment, easy to operate, only need to play raised insertion and bung and the bucket of lid hook 2 front end The junction of body, exerts a force downwards, simple to operate.

Further preferred is：Described handle 1 is 80 ° with the angle α playing lid hook 2.Select this angle in order to bucket The unlatching of lid.

Further preferred is：It is provided with backing plate 4 below described support bar 3.Being disposed to of backing plate 4 prevents from operating When, support bar 3 causes the damage of bung in the presence of the downward power of handle 1.

Further preferred is：Described backing plate 4 upper surface becomes obtuse angle with the angle playing lid hook 2 extended line.Backing plate 4 upper table Face becomes obtuse angle with the angle playing lid hook 2 extended line, is in order in operation, backing plate 4 is gradually added with the contact area of bung Greatly, center of gravity is moved back by, and reduces backing plate 4 pressure downward to bung.

The operation principle of the present embodiment and use process：

The raised insertion bung of lid hook 2 front end and the junction of staving will be played, now backing plate 4 is near the side playing lid hook 2 Contact with bung, downward power is applied to handle 2, play that lid hook the last 2 bung is piecemeal starts, the base surface of backing plate 4 and bung Amass and be gradually increased, move after center of gravity, reduce backing plate 4 pressure downward to bung.
