Description

1M

The invention relates to mechanical engineering, in particular, to fixing devices from relative axial movements of parts of a go-coupling device.

A fixation device is known from the relative axial movements of the envelope of the envelopes and of the parts covered, which comprise C-shaped elastic elements placed one against the other grooves of the covering part, interacting with the annular grooves of the male O.

A disadvantage of the known locking device is the low operational reliability associated with the possibility of the interacting parts exiting from the engagement at their specific mutually angular positions.

The purpose of the invention is to increase the reliability of axial fixation of Parts.

The delivered chain is achieved by the fact that in the fixation device from relative axial movements of the female part and the female part, containing C-shaped elastic elements arranged one opposite to the other slots of the female part, which interact with the annular grooves of the male part, the annular grooves are made of varying depth, and the grooves are offset friend relative to each other along the axis of the parts.

According to the second embodiment of the device, the annular grooves are also made of variable depth, and the C-shaped springs in cross-section are L-shaped, with their protruding parts directed towards the longitudinal axis of the fixed parts and shifted along each other along this axis.

FIG. 1 shows a fixative device, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in FIG. 3 a section B-B in FIG. 2; in fig. 4 - C-shaped spring (option); in fig. 5 - pin-bolt (version).

The device is intended to fix the female part I and installed in. its opening 2 encompasses the 6th part 3, which is the handle and the eccentric grooves 5, which interact with the fixing pin-lock bolt, is made in the V-section of the split C-shaped spring 6, mounted

292

in the groove 7 of the male part 1, this working part of the spring 6 in the form of a straight section-8 interacts with the groove 5 or with the protrusions 9 of the segment recess 10 with a radius R, and the projections 11 of the spring 6 bent against each other, with the part 1.

To increase the operational reliability and the possibility of axial movement of the part 3 to the closed position (in a strictly oriented position), the segment recesses 10 are axially biased by their width, and the slots 7 are also displaced. The grooves 7 can also be made without axial relative displacement if the projections 11 the springs 6 are equal to the width of the groove 5, and the width of the straight section 8, respectively, is equal to the half width of the groove (Fig. 4).

Eccentric grooves 5 parts 3 with eccentricity e can be performed with a relative angular displacement (Fig. 5). At the ends of the pin is equipped with a chamfer 12.

For convenience and reliability of operation, in order to prevent the gun 6 from falling out of the groove 7 when the part 3 is moved into the other female part 1, a split non-circular spring ring 14 is installed in the top eyelet in the groove 1 3, which is flush with a straight section in the groove 1 5 of the section B of the spring 6 designed To give it rigidity, or pins 17 are installed in the holes 16 (FIGS. 2 and 3).

After installing the springs 6 into the groove 7 and fixing them with a ring 14 or pins 1 7, the part 3 in position 1 of the handle 4 is installed in the opening 2 of the upper eyelet and pressed down to move, while at the same time reducing the spring 6 located closer to the handle 4 and when coinciding with the lower groove 5 it drops into it, and upon further movement of the part 3 into the groove, the second spring 6 also drops in. Thus, the gate valve is fixed in the open position without the possibility of axial movement.

The removal of the bolt pin (removal from the coupling bracket) is carried out as follows. Handle 4 is set to position C and; tighten up, while close to the handle the spring 6 comes out of the groove 5 and is located on the generatrix

(X, as a result of which the bolt pin moves freely to the half width of the groove 5, after which the handle is turned to the W position, now the spring 6 next to the handle appears on the generator "Further the bolt pin is removed from the part 1 ..

The device works as follows.

in a way.

After inserting the vehicle tongue earring into the open shed of the coupling bracket, the handle 4 is set to position I and by pressing it, the bolt pin is moved to the half width of the groove 5, then the hand is set to position and (near to the handle the spring is on the surface B) and the gate moves down; when meeting with the upper groove 5 syachala, the spring comes close to the handle, and after turning the handle 4 to position I, both springs 6, in a straight working section, interact with the protrusions 9 of the notch 10, securely fix the part 3 from both spontaneous turning . and from axial movement, i.e.

the bolt pin is closed. Switching the plug to the open position is performed in the reverse order.

Application of the proposed technical solution allows to increase the reliability of fixing parts from their axial movement.
