Description
Technical field
The utility model relates to a kind of stopper, particularly relates to a kind of stopper for automobile radiators relief opening.
Background technique
In automobile radiators transportation process, relief opening needs with a stopper shutoff.In prior art, the stopper of shutoff automobile radiators relief opening comprises plastic body, body is provided with attachment hole and outstanding closure part, closure part is equipped with O shape rubber seal.Body and closure part place are provided with through hole, and the far-end of the relative closure part of through hole is combined with rubber stopper.The stopper of this structure, due to needs three assembling parts, therefore the manufacturing tolerances of each part can superpose, thus causes relief opening easily to produce leakage.Further, because independent rubber seal must have the assembly line manufacturing and produce, therefore also easily leak source is produced at assembly line place.
On the other hand, need in radiator transportation process inner chamber to be filled with nitrogen to protect radiator, but whether be but difficult to observe nitrogen occurs to leak and underpressure.
Therefore those skilled in the art are devoted to develop a kind of radiator relief opening plug being convenient to observe pressure in radiator.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of radiator relief opening plug being convenient to observe pressure in radiator.
For achieving the above object, the utility model provides a kind of radiator relief opening plug, comprises body; Described body is provided with the hole that is located by connecting; Described body is provided with the rubber closure part of evagination; The center of described closure part is provided with the peep hole be communicated with radiator relief opening; Be positioned at described body side in described peep hole and be provided with observation leather cup.
Preferably, the center of described observation leather cup is provided with observation boss.
Preferably, the end face of described observation boss is lower than the end face of described body.
Preferably, described observation leather cup and described closure part are structure as a whole.
For strengthening sealability, the sealing flange being circumferentially provided with at least one loop of described closure part.
Preferably, the cross section of described sealing flange is semicircle.
For improving the reliability of assembling, the far-end of the relative relief opening in described closure part is provided with groove; Described body is provided with the projection corresponding with described groove; Described projection embeds in described groove.
Preferably, described closure part is respectively arranged with the first fitting flange and the second fitting flange in the both sides of described groove.
The beneficial effects of the utility model are: the utility model structure is simple, conveniently can observe pressure in automobile radiators, and good seal performance,
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of radiator relief opening plug, comprises plastic body 1, body 1 is provided with the hole 2 that is located by connecting.Body 1 is provided with the rubber closure part 3 of evagination, the center of closure part 3 is provided with the peep hole 5 be communicated with radiator relief opening, is positioned at body 1 side and is provided with observation leather cup 4 in peep hole 5.
The center observing leather cup 4 is provided with observes boss 4a, observes the end face of end face lower than body 1 of boss 4.Observe leather cup 4 to be structure as a whole with closure part 3.
The cross section of the sealing flange 3a being circumferentially provided with two loops of closure part 3, sealing flange 3a is semicircle.
The far-end of the relative relief opening in closure part 3 is provided with groove 3b, and body 1 is provided with the protruding 1a corresponding with groove 3b, protruding 1a embeds in groove 3b.Closure part 3 is respectively arranged with the first fitting flange 3c and the second fitting flange 3d in the both sides of groove 3b.
Relief opening plug utilizes screw hole 2 of passing through to be located by connecting to be located by connecting with radiator, then closure part 3 is inserted the relief opening of automobile radiators, therefore easy for installation.In automobile radiators transportation process, be filled with the nitrogen of certain pressure to its inner chamber, to protect radiator.After nitrogen is charged radiator, therefore observing leather cup 4 will have projection to a certain degree, by visual observations leather cup 4 and the displacement observing boss 4a, can judge the interior pressure condition of automobile radiators.Can, in the manufacture process of radiator relief opening plug, make observation boss 4a make redness by sulfuration process, observe to be more convenient for.
Because the closure part of whole automobile radiators relief opening plug is one-body molded, decrease part, therefore the accuracy of manufacturing of automobile radiators relief opening plug is greatly improved.On the other hand, because sealing flange 3a and closure part 2 are structure as a whole, therefore sealing flange 3a does not have assembly line, thus substantially increase the sealability of automobile radiators relief opening plug.
Through test, this radiator relief opening plug is air tight under high/low temperature alternation environment, air tight during radiator accumulating.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
