SU635307A1 - Quick-release clamp for connecting components with elastic washer - Google Patents

Description

one

The invention relates to the field of mechanical engineering and can be used in all sectors of the national economy in devices for connecting structural elements with elastic properties at the place of their connection.

A quick-release fastener is known for connecting parts, comprising a check with a shaped groove associated with the base part, as well as a key for turning the checks into a working position before interacting with the removable part. The key is pivotally attached to the base part and the check. The parts to be joined have protrusions on which a check is placed over the figured groove. Turning the handle of the receipt key tightens the details 1.

The disadvantages of this device are that it only provides the connection of parts with round flanges, moreover, of considerable dimensions, so that the key handle does not extend beyond the dimensions of the flange. A protruding grip may cause the clamp to open up by accidental exposure to external force.

Also known is a quick-release clip for connecting parts with an elastic gasket, containing a finger rigidly attached to the base part, a check with a shaped groove and a finger freely moving in it, and a removable key with a pin designed to transfer checks to work position 2. This device is technical essence and the achieved effect is closest to the invention.

The disadvantages of this clip, while providing a quick disconnect,

is that the tool cannot be used when the removable part cannot be covered with a key (when the hole is not at the edge of the removable part) and when there is no finger on the base part

free platform for curved slots. In addition, the implementation krtsvolisynyh iazov sleds technologically. The aim of the invention is to simplify

designs.

This is achieved by the fact that the finger is made with a groove for accommodating the pin of the key abutting the outer end of the removable part.

FIG. 1 shows schematically a clamp, in plan; in fig. 2 - the same, side view; in fig. 3 - clip, iodobtozhenny for development. The finger 1 with the check 2 is fixed on the base

parts 3 and mounted in a removable hole

details 4 up to the stop in an external gasket 5. Pin 6 of key 7 is inserted into groove 8, made on finger 1. In check 2, there is a flange groove 9, the wall of which, like the walls of groove 8 of finger 1, interact with the pin of key 7.

To connect the two parts, it is necessary to pin 1 with a check 2 attached to the base part 3, insert the bracket of the removable part 4 into the elastic strip 5 into the hole or into the elastic gasket 5. Insert the pin 6 of the key into the groove 8 and release the key 7 into the outer end of the removable part 4. Pressing the key with one hand, squeeze the elastic gasket 5, with your free hand, transfer the check 2 to the working position and remove the key. The check 2 in its working position is held by the elastic forces of the compressed gasket b and the shaped shape of the groove 9, the checks 2.

To disengage parts, insert pin 6 into groove 8 and rest key 7 on outer side of removable part 4. Press one key on key handle, squeeze elastic gasket 5, with free hand transfer check 2 to free position and remove key.

The proposed clamp design is easy to manufacture, expands the possibilities of using the clamp, since it does not require a free space on the base part, and makes it possible to use a quick-release clamp not only at the edge of the removable part, but also in any place.
