Description

Adjustable screw rod connecting piece

Technical Field

The utility model relates to a connecting piece technical field specifically is a lead screw connecting piece with adjustable.

Background

Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection. After two parts are connected, when the two parts are separated by the existing bolt, a nut at the end part of a bolt needs to be unscrewed, so that the existing bolt is inconvenient to use for the parts needing to be frequently disassembled and separated.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a lead screw connecting piece with adjustable to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a lead screw connecting piece with adjustable, includes lead screw and pipe, the inner chamber sliding connection of pipe has the inner skleeve, the tip welding of pipe has the second nut, be connected with the spring between the right-hand member of inner skleeve and the second nut, the inside of inner skleeve is equipped with the internal thread, the inner chamber spiro union of lead screw and inner skleeve, the outer wall of inner skleeve is equipped with banding arch, the inner wall of pipe is equipped with the spout, protruding and spout joint, the tip fixedly connected with circular shape end plate of pipe, the middle part of end plate is equipped with the round hole, the lead screw runs through and rather than clearance fit.

Preferably, the second nut is cylindrical, and a hexagonal groove is formed in the outer side of the second nut.

Preferably, the spring is in clearance fit with the inner cavity of the circular tube, and a hexagonal first nut is welded at the outer end of the screw rod.

Preferably, the inner sleeve is in clearance fit with the inner cavity of the circular tube, and the bulges and the sliding grooves are symmetrically arranged.

Preferably, the protrusion and the inner sleeve are integrally cast, and the end plate and the circular tube have the same diameter.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses utilize the pipe to run through two parts that need connect, the lead screw is twisted into the back inwards, and first nut receives outside thrust, and consequently the spring is elongated, and two parts compress tightly by the contractile force of spring, because the spring has certain flexible surplus, consequently can be under the condition of not dismantling, can separate, convenient to use.
