Description

Quick connector with good sealing performance

Technical Field

The utility model belongs to the technical field of the quick connector, especially, relate to a quick connector that leakproofness is good.

Background

The quick connector of outdoor usefulness has waterproof measure, it is through the lock sleeve rotatory assignment rubber circle lock more tight more, thereby fixed and play waterproof effect to the terminal, nevertheless because the one end of quick connector wiring must communicate, the rainwater drenches and flows on the crust of electric wire, in time the gap water that is little again all can permeate the inside at quick connector, this is because the cross-section of pencil is circular, and at the very least zero line and live wire in the wiring, if including the earth connection has three, how bind this several lines again and all can have certain gap on quick connector, the extrusion pencil only can let the gap reduce, the pencil crust is extruded, but the metal wire of the inside then can not, so current quick connector only seals through the extrusion in addition rubber circle, obviously the leakproofness shows the lack slightly.

SUMMERY OF THE UTILITY MODEL

The utility model provides a quick connector that leakproofness is good, this quick connector that leakproofness is good has solved the above-mentioned problem that proposes.

In order to achieve the above object, the utility model discloses a quick connector that leakproofness is good's concrete technical scheme as follows: the quick connector with good sealing performance comprises a large cap body and a locking assembly sleeved inside the large cap body, wherein the locking assembly comprises a locking ring, a flexible cover and an inner ring air bag, the locking ring used for being extruded is sleeved inside the large cap body, a through hole is formed in the locking ring, and the inner ring air bag is embedded inside the locking ring.

Furthermore, the inner ring air bag is provided with three through holes and is of an integral sealing structure.

Furthermore, an air cylinder is embedded into the top of the locking ring close to the inner wall, and a threaded sleeve for sleeving a screw is installed on the inner wall of the air cylinder.

Furthermore, a piston is installed at the bottom of the screw, and the outer surface of the air storage cylinder close to the bottom is communicated with the surface of the inner ring air bag through a guide pipe.

Furthermore, the large cap body is sleeved at the top of the main cap body, and a thread for locking is arranged on the main cap body.

Furthermore, the large cap body is in a hexagon bolt shape, and the side surface of the large cap body is provided with anti-skid stripes.

Borrow by above-mentioned technical scheme, the utility model provides a quick connector that leakproofness is good. The method at least has the following beneficial effects:

this quick connector that leakproofness is good, with the zero line, the live wire passes the hole of the inner circle gasbag that the flexibility was covered respectively with the power connection wire, again to the zero line, the live wire inserts the inside of the main cap body with the power connection wire, screw with the gas receiver top is twisted into with the screwdriver, let the inside air introduction of gas receiver cavity inside to the inner circle gasbag zero line, live wire and power connection wire surface extrusion, fill the gap, like this not only further to the zero line, the live wire is arranged and the waterproof sealing effect that plays with the power connection wire is better.

FIG. 4 is a fourth schematic illustration provided in this example;

FIG. 5 is a fifth schematic illustration provided in this example;

fig. 6 is a sixth schematic view provided in this example.

In the figure: the locking device comprises a main cap body 1, a large cap body 2, a locking assembly 3, a locking ring 31, a flexible cover 32, an inner ring air bag 33, a screw 34, a threaded sleeve 35, a piston 36 and an air storage cylinder 37.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.

As shown in figure 1, the quick connector that the leakproofness is good, set up screw thread on the main cap body 1, the inside screw thread that sets up simultaneously of the big cap body 2, the big cap body 2 will lock locking ring 31 more and more tightly like this, because this connects for current structure, here just does simple summary.

As shown in fig. 2-3, the present quick connector with good sealing performance of the present invention is a rubber ring, where the rubber ring is improved, firstly, the rubber ring in fig. 2 is provided with a hole embedded in the air cylinder 37, and the hole is close to the inner ring of the locking ring 31, because the locking ring 31 deforms when being squeezed, and the outer ring is used to deal with the deformation;

with the zero line, the through-hole on flexible lid 32 is passed respectively to three lines of live wire and power connection wire, flexible lid is so called as because there is the flexible lid 32 of extrusion effect also to have certain deformation to cooperate this joint locking, with the zero line, live wire and power connection wire are installed on the joint after, screw 34 is twisted into through with the screwdriver, let the inside gas of gas receiver 37 lead to the inside of the inside inner circle gasbag 33 that cup joints of flexible lid 32 through the pipe, inner circle gasbag 33 can be with the zero line, gap extrusion between live wire and the power connection wire epidermis is filled, just so can play better water-proof effects, and to the zero line, the suitability of live wire and power connection wire size is stronger, only inner circle gasbag 33 can expand to fill the gap can.

As shown in fig. 4, the quick connector with good sealing performance of the present invention has the inner ring air bag 33 provided with a through hole matching with the flexible cover 32, but the inner ring air bag 33 is of an integral sealing structure, and the hole therein does not make the inner ring air bag 33 not be sealed as a whole.

As shown in figure 5, the quick connector that the leakproofness is good, zero line, live wire and power connection wire mainly insert the inside copper spare that connects, fix with the copper screw, can see out the through-hole that has the cup joint at the top of copper spare from figure 5, the screw hole of assembly copper screw is seted up to the side.

As shown in fig. 6, the quick connector that the leakproofness is good connects at outdoor use, when the pencil at both ends to connecting the kickup, the rainwater drenches on the pencil surface, flows to the both ends that connect under the effect of gravity, as long as connect both ends to have the gap when the pencil is sealed, the rainwater will permeate the inside that connects, because the condition has too much when the installation, the condition certainly exists.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
