Abstract
The utility model relates to field of daily hardware, claiming an extension bar capable of being fast installed and dismounted. An extension bar capable of being fast installed and dismounted comprises a first end pipe, a first long pipe, a connection pipe, a second long pipe and a second end pipe from up to down, which are of the same outer diameter, wherein the first end pipe and the second end pipe are separately matched with an end pipe joint via interference fit for forming a first end pipe construction member and a second end pipe construction member; the two ends of the connection pipe are separately matched with a connection pipe joint via interference fit for forming a connection pipe construction member; the two ends of the connection pipe construction member are separately connected with a first end of the first long pipe and a first end of the second long pipe; the first end of the first long pipe is connected with the first end pipe construction member, the second end of the second long pipe is connected with the second end pipe construction member. The extension bar capable of being fast installed and dismounted of the utility model can be fast installed and dismounted at any length, which is simple and convenient in use.
Description
Technical field
The utility model relates to the haberdashery and hardware field, particularly be a kind of quickly assembled and disassembled extension bar.
Background technique
In the prior art, long peg is single stock or is threaded by several sections quarter butts and forms.Single stock is owing to length relation makes transportation, deposits and bring difficulty; Several sections then mounting or dismounting inconvenience that quarter butt forms by being threaded.
Summary of the invention
At the removable stock of prior art is to be threaded, and has the defective of dismounting inconvenience, and the utility model provides a kind of extension bar that can install and remove fast.
For achieving the above object, the utility model adopts following technological scheme:
A kind of extension bar of quick mounting or dismounting, comprise the first end pipe that external diameter is identical from top to bottom, first long tube, connecting tube, second long tube, the second end pipe, the described first end pipe, the second end pipe respectively with end pipe joint interference fit, form the first end pipe component, the second end pipe component, described connecting tube two ends respectively with connecting tube joint interference fit, form the connecting tube member, described connecting tube member two ends respectively with second end of first long tube, first end of second long tube connects, first end of first long tube is connected with the first end pipe component, and second end of second long tube is connected with the second end pipe component.Long tube is Spielpassung with being connected of each member.The length of long tube can be by user and transportation demand and is decided, and makes a series.If when needing long length, available a plurality of connecting tube members and a plurality of long tube are accumulated to the length that needs.
As preferably, the homonymy of the described first end pipe component and the first long tube joint is symmetrical arranged radially slotted hole A, slotted hole B radially up and down, described radially slotted hole A, radially slotted hole B run through first long tube with the end pipe joint, radially slotted hole A, radially between the slotted hole B suspension hook is installed.The interior edge of suspension hook is stuck in two slotted hole walls, and the first end pipe component firmly is connected with first long tube, and also available lifting rope is directly fastened.When the need dismounting, remove lifting rope or suspension hook, the end pipe component just separates easily with long tube.
As preferably, have radially circular hole on described first long tube and the outer wall that the connecting tube member is connected, described radially circular hole runs through first long tube and connecting tube joint, the pin that floats radially is installed on the circular hole, the centre of unsteady pin has counterbore, card has jump ring on the inwall of connecting tube joint, and the other end of jump ring stretches in the counterbore.Jump ring can make first long tube firmly be connected with the connecting tube member, during dismounting, presses the pin that floats, and long tube just can withdraw from from the connecting tube member, reaches the purpose of quick mounting or dismounting.
The extension bar energy random lengths ground fast assembling-disassembling of a kind of quick mounting or dismounting of the present utility model uses simple, convenient.
