Description

A kind of telescopic pipe that has safe button snap close

Technical field

The utility model relates to a kind of telescopic pipe, especially relates to a kind of telescopic pipe with safe button snap close.

Background technique

Existing telescopic pipe, often not too safe fixedly the time, stable, a kind of to have safe and stable telescopic pipe be the purpose of this utility model so invent.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of telescopic pipe that has safe button snap close.

For solving the problems of the technologies described above, the utility model adopts following technological scheme: it comprises telescopic pipe and snap close;

Described telescopic pipe comprises outer tube and interior pipe; Snap close is established in the end of described telescopic pipe outer tube; The top of pipe is provided with a round groove in the described telescopic pipe;

Described snap close comprises button, pin, spring sheet, lock tube and retaining screw; Described lock tube is fixed on the end of telescopic pipe outer tube by the retaining screw that is located at the lock tube bottom; The top of described lock tube is provided with a groove, and described button is arranged in the groove of lock tube top, and described button and lock tube are fixed together by pin, and the two ends of described pin are fixed on the sidewall of groove, and described button can rotate around pin; The afterbody of described button is provided with fixedly empennage, fixedly is provided with the hole that can pass in and out up and down for empennage on the telescopic pipe outer tube below the empennage at this; The front end of described button is a pressure handle, be provided with spring sheet between the groove above this pressure handle below and the lock tube, the surface of contact of this spring sheet and groove is provided with aperture, is provided with projection with the groove of aperture matched position, this projection is passed the aperture on the spring sheet, the moving of control spring sheet.

For increasing the joint number of telescopic pipe, a round groove is established in described telescopic pipe outer tube top, and the outside of this telescopic pipe outer tube is provided with the pipeline that has snap close; Constantly increase snap close and the pipeline that has hole slot, can make telescopic pipe meet the requirements of length.

Working principle of the present utility model is as follows: when not pressing the button, the fixedly empennage of button afterbody passes the hole on the telescopic pipe outer tube of being located at of this empennage below, and fixedly empennage passes a hole slot of the top of pipe in the telescopic pipe simultaneously; Pipe and outer tube were fixed in fixedly empennage will stretch, and the pipe outer tube can not freely stretch in making.The pressure handle that presses the button, button rotates around pin, and fixedly empennage is upwards mentioned, and breaks away from the hole slot of pipe top in the telescopic pipe, and at this moment, interior pipe can stretch and be drawn to the position that needs; Put down button, owing to be provided with spring sheet between the groove of pressure handle below and lock tube top, this spring sheet makes pressure handle appear on the stage, fixedly empennage decline, and fixedly empennage passes the corresponding hole slot of the top of hole on the telescopic pipe outer tube and the interior pipe of telescopic pipe again; Fix telescopic pipe.

The utlity model has advantages such as safe in utilization, flexible convenient.
