Abstract
A kind of explosion-proof type easy open cover, including lid body, unlatching tongue piece, draw ring, lid body is provided with finger groove, wire size and type；Opening tongue piece is to be formed by processing tongue piece line of weakness on lid body, and draw ring is connected by being positioned at the rivet at lid body plane center with lid body；Opening the both sides near rivet area for the tongue piece surface by explosion-proof line carver directly extruding to capping, make material produce to be plastically deformed, and forming two explosion-proof grooves, described two explosion-proof grooves are symmetrical with regard to the horizontal axis of lid body, and parallel with tongue piece line of weakness；Described unlatching tongue piece both sides are additionally provided with strengthening rib strip.The utility model is by arranging explosion-proof groove and strengthening rib strip, enhance the intensity opening tongue piece position, can efficiently solve because of at tongue piece line of weakness stress concentrate and produce open the problem that pops of tongue piece moment, prevent opening tongue piece by the design of deep mixed tongue piece line of weakness simultaneously and pop and tear.
Description
Technical field
The utility model relates to a kind of easy open cover, especially a kind of explosion-proof type easy open cover.
Background technology
Easy open cover common at present, frequently with the shape shown in accompanying drawing 1 and construction, the 3rd, draws including the 1st, lid body opens tongue piece
Ring 7, lid body is provided with finger groove the 5th, wire size 6 and type 8, and opening tongue piece 3 is to be carved by processing tongue piece on lid body 1
Trace line 2 and formed, draw ring 7 is connected by being positioned at the rivet 4 at lid body plane center with lid body 1, and this easy open cover is at tongue
Stress at notching line 2 is excessively concentrated, filling after, under the effect of tank internal pressure, during unlatching, open tongue piece 3 easy moment quick-fried
Open, thus injury is produced to consumer.
Utility model content
For overcoming disadvantages mentioned above, the utility model provide one can be prevented effectively from easy open cover open tongue piece pop, protect
Protect the explosion-proof type easy open cover of consumer safety.
A kind of explosion-proof type easy open cover, including lid body, open tongue piece, draw ring, lid body be provided with finger groove, wire size, with
And type；Opening tongue piece is to be formed by processing tongue piece line of weakness on lid body, and draw ring and lid body are by being positioned at lid originally
The rivet of body planar central is connected；Opening the both sides near rivet area for the tongue piece surface by explosion-proof line carver to capping
Directly extruding, making material produce and be plastically deformed, and form two explosion-proof grooves, described two explosion-proof grooves are horizontal with regard to lid body
Axis is symmetrical, and parallel with tongue piece line of weakness；Described unlatching tongue piece both sides are additionally provided with strengthening rib strip.
Further, the two-end-point of described explosion-proof groove to the distance of the horizontal axis of lid body be respectively 3.93mm and
1.94mm；The two-end-point of described explosion-proof groove is respectively 3.85mm and 1.78mm to the distance of lid body longitudinal central axis line.This reality
With the distance length of the explosion-proof groove in novel and with open tongue piece, the position relationship of rivet is all through great many of experiments design
On the basis of the preferred plan that draws.It can effectively reduce unlatching tongue piece moment while ensureing to facilitate user to open easy open cover
The probability popping.
Further, the described tongue piece line of weakness degree of depth is uneven, is divided into three degree of depth, be respectively 0.04 0.08mm,
0.01—0.03mm、0.03—0.06mm.By the design depth in zones of different for the tongue piece line of weakness, reach tongue piece line of weakness
The power relatively of each position intensity prevents opening tongue piece and pops and tear.
A kind of explosion-proof type easy open cover that the utility model provides, by arranging explosion-proof groove and strengthening rib strip, enhances unlatching
The intensity at tongue piece position, can efficiently solve because stress is concentrated and tongue piece moment of opening of producing pops at tongue piece line of weakness
Problem, thus avoid consumer by unnecessary injury, improve the safe mass of product, simultaneously by deep mixed tongue
The design of notching line prevents opening tongue piece and pops and tear.

Fig. 2 is the structural representation of the utility model a kind of explosion-proof type easy open cover；
Fig. 3 is the structural representation with unlatching tongue piece for the explosion-proof groove of the utility model a kind of explosion-proof type easy open cover；
Fig. 4 is the structural representation of the lower chopping block of shaping of the tongue piece line of weakness of the utility model a kind of explosion-proof type easy open cover.
Detailed description of the invention
In order to preferably the utility model is illustrated, elaborate below in conjunction with accompanying drawing.
As Figure 1-4, a kind of explosion-proof type easy open cover, including the 1st, lid body opens tongue piece the 3rd, draw ring 7, lid body 1 sets
Have finger groove the 5th, wire size 6 and type 8.Opening tongue piece 3 is to be formed by processing tongue piece line of weakness 2 on lid body 1, draws
Ring 7 is connected by being positioned at the rivet 4 at lid body plane center with lid body 1.Opening tongue piece 3 surface near rivet 4 region
Both sides by explosion-proof line carver directly extruding to capping, make material generation be plastically deformed, and form two explosion-proof grooves 12,
Described two explosion-proof grooves 12 are symmetrical with regard to lid body horizontal axis 11, and parallel with tongue piece line of weakness 2.Explosion-proof groove 12
Design can effectively strengthen open tongue piece 3 position intensity, effectively solve easy open cover open when, open tongue piece 3
The problem that moment pops, meanwhile, the structure of symmetric design, open tongue piece 3 two ends uniform force, open safer.Described open
Opening tongue piece 3 both sides and being additionally provided with strengthening rib strip 10, strengthening rib strip 10 equally strengthens opening the intensity at tongue piece 3 position so that this
Utility model product is in use safer.
Concrete, the distance of two-end-point A, B of explosion-proof groove 12 to the horizontal axis of lid body 11 be respectively 3.93mm and
1.94mm；Two-end-point A, B of described explosion-proof groove 12 to the distance of lid body longitudinal central axis line 9 be respectively 3.85mm and
1.78mm.The distance length of the explosion-proof groove 12 in the utility model and be all with the position relationship opening tongue piece the 3rd, rivet 4
The preferred plan drawing on the basis of great many of experiments designs.It can ensure to facilitate user while opening easy open cover effective
The probability that reduction unlatching tongue piece 3 moment pops.Tongue piece line of weakness 2 degree of depth is uneven, is divided into three degree of depth, is 0.04 respectively
0.08mm、0.01—0.03mm、0.03—0.06mm.It realizes that process is, by the lower each work of chopping block 13 of tongue piece line of weakness shaping
Making the relative height differential between face to adjust the depth of tongue piece line of weakness 2, the high local tongue piece line of weakness 2 of working face is deep, this
Place's tongue piece line of weakness 2 intensity difference；The low local tongue piece line of weakness 2 of working face is shallow, and tongue piece line of weakness 2 intensity is strong.By design tongue
The depth in zones of different for the notching line 2, the power relatively reaching each position intensity of tongue piece line of weakness 2 prevents from opening tongue
Piece 3 pops and tears.
Above-mentioned detailed description of the invention is not construed as limiting further to of the present utility model, those skilled in the art according to
The unsubstantiality change that the utility model content is made all should fall in the utility model protection domain.
