Description

The invention relates to the connection of parts, namely to the threadless connections and can be used to connect parts when assembling devices related to various fields of technology.

Known quick disconnect device for connecting parts containing the parts to be joined and a leaf spring mounted on one of them and connected to the other, while the leaf spring is made with several bent petals, longitudinal inclined grooves in which are placed the leaves of the leaf spring are placed on one of the parts to be joined (copyright certificate №785563 for the invention "QUICK DISCONNECTED DEVICE FOR CONNECTING DETAILS", IPC F16 B2 / 20, published 12/07/1980).

Known quick coupling containing the ends of the two parts, while at one end made the socket in the form of a hollow box-shaped housing, and on the other there is a plate spring. The body is made with one longitudinal groove and two transverse grooves adjacent to the longitudinal groove. The spring has connected straight and arcuate portions. At the free end of the arcuate section there are two projections. The ends of the parts are joined when placing a straight section of the spring in the body cavity and in the longitudinal groove, the arcuate section is placed in the body cavity, and the protrusions of the arcuate section are located in the blind ends of the transverse grooves (copyright certificate No. 1730477 for the “QUICK CONNECTION” invention, IPC F16 B2 24, 17/00, published 04/30/1992).

Known quick coupling containing covered part with a flat and slot, perpendicular to its longitudinal axis, covering the part with a shaped groove and similar in location to the slot and C-shaped elastic element located in the combined slot of both parts (RF Patent No. 2260148 for the invention “FAST-JUMPER”) DETAILS ", IPC F16B 21/18, published 10.05.2005).

Known detachable connection parts containing the first and second parts, which is made, respectively, the window and the protrusion, providing the engagement of parts. Through the window of the first part, interacting with it, a flat curved spring fixed on the second part is missed (US Patent No. 3,503,641 for invention, IPC E04B7 / 02; E04D12 / 00; F16B2 / 24; F16B9 / 02, published March 31, 1970).

A disadvantage of the known compounds is low reliability, since the retention of parts is carried out only by the elastic forces of the spring.

Known quick-disconnect flange connection of cylindrical parts, comprising a male part with deaf rectangular grooves evenly distributed around the circumference, encompassing the part with through rectangular grooves coinciding with the grooves of the male part, ring segments installed in the aligned grooves of the above-mentioned parts, flush with the surface of the female part, fixing unit ring segments and a tread on the covering parts. Outside the female part and the ring segments, a common annular groove is machined, in which a spring ring is placed, which serves as a fastener. On the inner cylindrical surface of the ring segments formed lead-in chamfer facing the end of the covering parts. As a protector, a shell is used, tightened by a cap nut (RF Patent No. 2615108 for the invention of the QUICK-DETACHABLE CONFLICTED CONNECTION OF CYLINDRICAL DETAILS, IPC F16B 21/18, published on 03.04.2017). The disadvantage of the known compounds is a complex structure that makes it difficult to automate the process of assembling finished products, for example, having a flat mating surface.

Known closest to the claimed invention by the combination of essential features and selected as a prototype detachable connection parts containing the first (covered) and the second (covering) parts with support surfaces, the first part has a protruding part, the second part has elements covering the protruding part the first part; mating parts have flat surfaces; the parts are fixed in the direction of the connector by means of fixation, including elastic and locking elements. As an elastic element, an elastic plate is used, which, together with the protruding part of the first part, is enclosed by elements of the second part, and the stopping elements are protrusions located at least one on the protruding part of the first part and on the second part with the possibility of interaction with mutually opposite the edges of the elastic plate (inventor's certificate No. 957446 for the invention of “CONNECTING DETAIL CONNECTION”, IPC H 05 K 7/12, F 16 V 17/00, published 07/07/1982).

The known compound is also characterized by the complexity of the design, complicating the mechanization and automation of the assembly process of the product.

The task, the solution of which the claimed technical solution is directed, is the creation of a simple in constructional design, technological in manufacturing and convenient in assembly of a detachable connection.

The technical result achieved as a result of solving the task set is to simplify the design and enable the automation of the product assembly process with flat mating surfaces, which allows reducing labor costs and reducing the cost of the finished product.

This technical result is achieved by the fact that the detachable connection of parts contains the first (male) and second (female) parts with supporting surfaces, wherein the first part has a protruding part, the second part has elements covering the protruding part of the first part; mating parts have flat surfaces. Details are fixed in the direction of the connector by means of fixation, including elastic and locking elements. The mating surfaces of the first (covered) part and the second (covering part) contain aligned longitudinal grooves. Grover’s washer, which is installed between the supporting surfaces of the first and second parts, was used as an elastic element. The elements covering the protruding part of the first part are two parallel shelves, made with the possibility of placing between them covered parts. As the locking elements used plates made with the possibility of backlash-free installation in the holes formed by combining the longitudinal grooves on the mating surfaces of the first and second parts.

In some cases, the execution of the locking plate can be U-shaped, made with the possibility of backlash-free installation of the free ends in the holes formed when combining the longitudinal grooves on the mating surfaces of the first and second parts.

Comparative analysis of the claimed invention with the prototype showed that it differs from the known, closest technical solution:

- the presence of combined longitudinal grooves on the mating surfaces of the first (male) part and the second (female) part;

- using Grover's washer as an elastic element;

- the execution of the washer Grover installed between the supporting surfaces of the first and second parts;

- the implementation of the elements covering the protruding part of the first part in the form of two parallel shelves with the possibility of placing between them covered parts;

- use as locking elements plates made with the possibility of backlash-free installation in the holes formed when the longitudinal grooves on the mating surfaces of the first and second parts are combined.

In some cases, the execution of the proposed technical solution differs from the known U-shaped shape of the locking plates, made with the possibility of backlash-free installation of the free ends in the holes formed by combining the longitudinal grooves on the mating surfaces of the first and second parts.

The proposed technical solution is characterized by simplicity of design and provides a reliable fixation of the detachable connection with the possibility of mechanization and automation of the process of assembly and disassembly. The implementation of the elements covering the protruding part of the first part, in the form of two parallel shelves with the possibility of placing the covered part between them, and the presence of compatible longitudinal grooves on the mating surfaces of the first (covered) part and the second (covering) part, ensures the formation of longitudinal slots when the parts and allows you to use as a stopper plate elements, which simplifies the procedure for connecting parts and the possibility of its mechanization. The backlash-free installation of the plates increases the reliability of the connection. Making plates U-shaped with the possibility of backlash-free installation of free ends in the holes formed when combining the longitudinal grooves on the mating surfaces of the first and second parts, reduces the labor costs for the Assembly. Using Grover's washer as an elastic element provides a reliable connection, allows you to simplify the design, mechanize and automate the assembly process.
