Description

"CONSTRUCTIVE PROVISION APPLIED IN QUICK HITCH"

This utility model patent application refers to a "FAST Hitch CONSTRUCTIVE ARRANGEMENT" which has been developed to allow the manufacture of various parts of the plastic quick coupler, enabling cost savings, safety, durability Easy maintenance and repair in the replacement of components combined with plastic material that ensures high mechanical strength, allowing the system to be quickly connected and disconnected.

Currently there are numerous equipment, both industrial and residential, which generally use a type of quick coupler for its operation. These fittings should be coupled without twisting the hose, ensuring their factory constructive integrity, as such hose is resistant to pressure, flexibility and temperature, but should not be twisted as it would cause irreversible damage to it. Thus, the quick coupling for its practicality is currently the most used device especially when there is a need to connect and disconnect the system frequently. .

Nowadays the quick couplings are manufactured from forged brass, machined and that later receive the nickel plated finish, this procedure increases the cost of the product, which often makes it impossible to replace parts of the device, which obliges the user. to purchase a new set.

Brass is the generic name of alloys whose main constituents are copper and zinc, with a lower proportion of zinc; having application in the manufacture of accessories for bathrooms, taps, registers and fittings, as it is a material in which no oxidation occurs.

Another material that is beginning to emerge in quick coupler manufacturing is zamak, which is the designation of alloys containing about 95% Zn (Zinc), together with Al, Mg and Cu, whose melting point is between 385 ° C and 400 ° C. In the industry various Zamak alloys are used, with different Al, Mg and Cu contents, which results in different mechanical properties. They are low cost materials used in the casting of parts that require little mechanical resistance. Liquid material is injected under pressure into molds in the shape of the parts to be produced.

Among the technical applications of zamak are: automotive carburetors, pressure regulating valves for gas cylinders and accessories for electrical installations (bushings, junction boxes, curves, etc.). It turns out that castings and injections made from zamak contain a huge degree of porosity which decreases the strength of the material.

Because of these and other unspecified drawbacks the inventor has developed the "FAST HITCH CONSTRUCTIVE ARRANGEMENT", comprising a main body formed from a cylindrical sleeve, the outer section of which is radially provided with reinforcement rings while its inner section at the lower end. its diameter is reduced to form a retaining wall followed by a locking ring, said glove being coupled to a connection, provided with a tapered male coupling provided at its lower elliptical relief section forming a locking channel, followed immediately by a housing channel where a snap ring is inserted, while the retaining channel receives retaining pins above which a spring-loaded washer is housed, said connection being provided at its upper outer section with a hexagon with an internal thread, below which there is a ring. which is compressed by the post plug, and in a c Derivative construction The connection is provided with cross-section for coupling balls that promote the locking of the spring, characterized by the grape, the connection and the plug to be composed entirely of plastic material obtained from injection.

For a better understanding of the present utility model, a detailed description of the same is given below by reference to the accompanying drawings, where:

Figure shows an exploded perspective view.

Figure 2 shows an exploded perspective view of the derivative arrangement.

Figure 3 shows a derivative exploded perspective view.

As illustrated by the figures and in their details, the "FAST Hitch-applied CONSTRUCTIVE ARRANGEMENT", comprising a main body (1) formed from a cylindrical sleeve (2) whose outer section (3) is provided radially with reinforcing rings (4) while its inner section (5) at the lower end (6) has its reduced diameter forming a retaining wall (7) followed by an interlocking ring (8), said sleeve (2) being coupled to a connection (9) , provided with a tapered male coupling (10) provided on its lower section (11) with elliptical relief (12) forming a locking channel (13), followed immediately by a housing channel (14) into which an elastic ring (15) is inserted, while the retaining channel (13) receives retaining pins (16) above which a spring-loaded washer (17) is housed (18), said connection (9) provided in its upper outer section (19) of a hexagonal one. (20) with internal thread, below which there is a sealing ring (21) which is compressed by the spike plug (22), and in a derivative constructive arrangement the connection (9) is provided with furostransversal (23), for ball coupling (24) which promote spring locking (18), characterized by the grape (2), the connection (9) and the plug (22) to be made entirely of plastic material obtained from injection.

Based on what is described and illustrated we can see that the "CONSTRUCTIVE FAST Hitch CONSTRUCTIVE ARRANGEMENT" has huge advantages as the quick coupler has plastic body and fittings, so they are lighter and more compact than the metal fittings that were developed to ensure excellent robustness and impact resistance, meeting the need for application in environments with varying temperatures.

It should also be noted that the connections are practical and quick and can be reused thousands of times without compromising the perfect pneumatic and mechanical seal. Available in various configurations, it ensures unlimited application flexibility in segments such as robotics, food industries, automotive, machine tools, packaging machines, among others.

Because it is made of plastic, its cost of manufacturing and resale is infinitely lower than that of metal-produced couplings. Because it meets all the requirements that define the utility model patent, since it has combined and modified known elements, giving them an innovative and industrializable general aspect, and modifications that can be made without departing from the spirit and scope of the present patent, the following are its claims.
