Abstract

The utility model relates to a telescopic pipe connector, which is provided with a sleeve pipe which is fixed on the upper side of a pipe joint by screw threads. The surface of the sleeve pipe is provided with a screw thread hole in which a regulating screw is screwed. The pipe joint is inserted in the sleeve pipe, and is provided with a long slot. A bolt can slide backwards and forwards. According to the length of the pipe joint, extending into the sleeve pipe, the pipe joint is screwed to be fixed. The telescopic pipe connector can be served as table legs, a floor lamp holder and clothes hanger stands, and the length of the telescopic pipe connector can be randomly adjusted.

Description

Telescopic pipe connector

The utility model relates to a kind of telescopic pipe connector, belongs to the technical field of connecting element.

Tubing is the connection of part in addition, always utilize the part connection in addition of welding or pipe coupling flange pipe, its length can not be regulated, its narrow limitation is arranged in the use, sometimes, fall as the lamp stand of table leg, clothes hanger, floor model desk lamp and stool leg or the like, the connection of the similar pipe fitting of its shape, all requirement can be regulated its length as required arbitrarily, and therefore needing a kind of link can achieve this end.

The purpose of this utility model is that a kind of telescopic pipe connector will be provided, and it can overcome above-mentioned deficiency, can change pipe fitting length as required and be fixed.

The purpose of this utility model be this realize, it has a sleeve pipe to fixedly connected with screw thread with a pipe fitting, another pipe fitting and the other end of sleeve pipe can be pegged graft, and the sleeve pipe side in addition of sleeve pipe is provided with a tapped hole, and there is an elongated slot on another pipe fitting surface, the width of groove is suitable with the external diameter of tapped hole, be screwed into the adjustment screw in the tapped hole of sleeve pipe, enter again in the elongated slot of pipe fitting, screw can slide in elongated slot, pipe fitting is stretched in the adjustment sleeve pipe just fixed, pipe fitting (2) can not be rotated in sleeve pipe with screw to certain length.Pipe fitting (2) passes cushion block (4) and directly stretches in the pipe fitting (1).

The schematic representation of Fig. 1 telescopic pipe connector

Fig. 2 cushion block sectional view

The A of Fig. 3 cushion block is to view

Now in conjunction with the accompanying drawings the structure of telescopic pipe connector is described in detail.

By Fig. 1, one end of pipe fitting (1) have external screw thread can with the female thread of sleeve pipe (3) right-hand member endoporus, sleeve pipe (3) and pipe fitting (1) are become one, another pipe fitting (2) is inserted in the sleeve pipe (3), there is tapped hole (8) on sleeve pipe (3) surface, be screwed in the hole and adjust screw (5), there is an axial elongated slot (9) on pipe fitting (2) surface, the aperture of groove width and tapped hole (8) adapts, can stretch into sleeve pipe to pipe fitting (2) to certain length as required, use screw (5) plug-in unit in elongated slot (9), to be fixed again, also install a rubber cushion blocks (4) between pipe fitting (1) and (2) additional, cushion block (4) also is a tubulose part in addition, and its distal end faces has double wedge (10) and groove (11), pipe fitting (2) be can be screwed part (not representing on the figure) in addition, can not have screw thread yet.

Fig. 2 is the cushion block sectional view, and cushion block (4) also is a tubulose, is made by rubber or metallic material.

Fig. 3 be the A of cushion block to view, the end face of cushion block (4) has double wedge (10) and groove (11), the also turning-in of end of double wedge (10) has distortion slightly behind the pressurized, make cushion block (4) compress pipe fitting (2).

This structure is applicable to that as table leg the part in addition of the lamp socket leg clothes hanger of floor model desk lamp makes it can adjust height arbitrarily.

Compared with prior art this telescoping tube connector has following advantages:

1, simple in structure, be easy to make, cost is low;

2, be used for table leg, floor model Bulb holder of table lamp leg, floor model fan and clothes hanger and can adjust its height as required arbitrarily.

Claims

1, a kind of telescopic pipe connector, the right-hand member endoporus that it is characterized in that sleeve pipe (3) has female thread to match with the external screw thread of pipe fitting (1) one end, link into an integrated entity, there is elongated slot (9) on pipe fitting (2) surface, be inserted in the sleeve pipe (3), there is tapped hole (8) on sleeve pipe (3) surface, is screwed in the hole to adjust screw (5), it is fixing pipe fitting (2) that screw (5) end enters the elongated slot of pipe fitting (2), and cushion block (4) also is housed between pipe fitting (1), (2).

2, connector according to claim 1 is characterized in that cushion block (11) also is a tubulose part in addition, and its end face has double wedge (10) and groove (11), and the end of double wedge (10) is also inwardly crooked slightly.
