A pulling device with self-locking function

Abstract

The invention discloses a drawing device with a self-locking function, which includes a drawing tube and a recovery device for driving the drawing tube to reset, and also includes: a fixed body, at least two friction modules, and each friction module is rotatable and mounted on the fixed body for up and down movement; the drawing tube moves through the fixed body and is clamped between the at least two friction modules, and the drawing tube can drive the at least two friction modules to rise or fall through friction Or rotate; a buckle module, the buckle module is connected and matched with the friction module, and can be locked or unlocked through the upward movement of the pull tube, and the buckle module restricts the movement of the friction module in the locked state, so that the friction module The restriction drawing tube is reset, and the buckle module releases the restriction on the friction module in the unlocked state. The invention enables the drawing tube to be automatically maintained in the drawn state after being drawn, thereby freeing the user's hands and making the user more relaxed and convenient during use.

Description

technical field [0001] The invention relates to a drawing device, in particular to a drawing device with a self-locking function. Background technique [0002] At present, there are many pullable water outlet terminals in the prior art, such as pull-out showers, pull-out faucets, etc., which are connected with a pull-out tube. When the pull-out function is not required, the water outlet terminal is generally positioned on the installation table. When it is necessary to use the pull function, the user only needs to pick up the water outlet terminal and pull up the pull tube to move the water outlet terminal to a suitable position for water outlet, which is convenient for users to wash hair, face, etc. However, due to the pull-out water outlet terminal, the pull-out tube relies on a weight or other heavy objects to reset when it falls, so that when the user uses the pull-out function, the user needs to hold the water outlet terminal all the time, otherwise the pull-out The t...

However, due to the pull-out water outlet terminal, the pull-out tube relies on a weight or other heavy objects to reset when it falls, so that when the user uses the pull-out function, the user needs to hold the water outlet terminal all the time, otherwise the pull-out The tube will fall and reset under the action of the weight of the hammer, which makes the user easy to fatigue and very inconvenient during use
