Description

 : i interacting with a retainer, which is made in the form of an eccentric with a self-locking system with a profile and is fitted with a P. tangential hole with a possibility of rotation, for example, and that on the petals there are bevelled bevels.

FIG. 1 shows a locking device, a longitudinal section; on f; And 2 is a section L-A in FIG. one,

The locking device contains a nut /, f.IKSator 3 as an eccentric 2, located with its supports from the tangential hole, - 3 nuts. In soldering / vypolii and through figured groove 4 forming with the threaded part of the nut petals 5 interacting with the ends of their smooth surfaces 6 with the eccentric surface 7 of the retainer 2, zapol.nennoy with sa 10z5gshch / ims profile motor. At the ends of the petals 5. The bevels 8, wedge: aI | mAy ocution of their own tops with a threaded surface | (() are fixed; 9. The sleeve 10 and the girder J1 keep the lock 2 from falling out.

The threaded rod 9 is installed in the housing 12 and is rigidly connected to the lifting platform 13. From turning when adjusting), the shaft 9 and the rod 9 holds the shipper 14, fastened under it.

The operation of the fixing device is 3 as follows.

Rotating 3 one or the other side of the nut / raise or lower the threaded stem 9 with the platform 13. Then, by turning the lock 2, the end of the nut / of the threaded rod 9 is compromised. At the same time, 3: Xceitrico surface 7, abut the inner surface; nost 6 leivestocks 5, ynijyro. tightens their ends with bevels i3 radial direction in the direction of the axis of the threaded rod 9. Bevels 6, slamming into the threaded surface, are a reliable fixation of the nut / from the iron on the threaded

rod 9 in both directions. From time to time, the gates (crossover) retainer 2-barrels: in elastic forces | 1 leistka 5 for the sake of deceleration of the well-known property irofl 7, vypolienio l-ha eccentric 2.

Disassembling the nut of the axles with cts by turning the fixer 2 in the opposite direction.

At the same time, the eccentric surface 7 moves away from the smooth surface of the 6 petals 5. The ampoules and 5 are iodine, by the action of the spring forces, return to their original position. After that, the nut / can freely rotate in a circle of threaded C7cr; k; 1 9.

A fixing device, containing a threaded rod, a nut and at least one lock, located in the laiigenZliny hole of the nut, interacting with a threaded rod, and that, with the aim of unwinding the area of use, and the stopper; and -raiiKii with any given position, and, in the nut, a through-shaped shaped groove is made, communicating with the tangentshal; the 1st hole and forming a nut with the threaded part of the nut and interacting with the PI | XatorO: M, which you look like eccentric The trick is equipped with a self-braking cable with a profile and is installed in a tangential hole with the possibility of rotation, with bevels at the ends of the lenestk.

Claims (1)

A fixing device comprising a threaded rod, a nut, and at least one retainer located in the tangential hole of the nut, interacting with the threaded rod, which requires that, in order to expand the area of use by ensuring the locking of the nut in any given position, a through-shaped groove is made in the nut, communicating with the tangential hole and forming petals with the threaded part of the nut, directed by the vertices to each other and interacting with the latch, which is made in the form of teat with self-locking profile and is mounted in the tangential hole rotatably eto.m at the ends of the petals are made bevels.
