Description

Telescopic drop-down formula (window) curtain fixing device

Technical Field

The utility model relates to a life furniture ornament field, especially railway carriage service type instrument.

Background

Curtains have been an indispensable decoration for home life since ancient times. With the rapid development of economy, the roller shutter appears in the public visual field and slowly replaces the traditional cloth curtain by the characteristics of simple structure, beautiful arrangement and strong applicability. However, unlike the conventional curtain, the pull-down curtain needs a fixing device to fix the curtain rod when functioning, but most of the existing curtain fixing devices are fixed and protrude on the wall. Most of the fixing devices are designed to be protruding from the tips, so that the rolling shutter rod is convenient to fix, and accidents are easily caused at the same time. Therefore, in order to solve the problem that harm is caused by the curtain fixing device while the curtain is fixed, the telescopic pull-down type curtain fixing device is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a telescopic drop-down type curtain fixing device with simple structure and beautiful appearance, which is used for solving the problems appearing in the background.

In order to achieve the above object, the utility model provides a following technical scheme: a telescopic pull-down curtain fixer is composed of curtain fixer with arc slot for fixing curtain rod, casing, driver with inclined block and button, and spring in the slot for ejecting out the curtain rod. The window curtain comprises a shell, a window curtain fixing device, an inclined block transmission device, a transmission button transmission device and a transmission button transmission device, wherein the shell is provided with a pin for fixing a connecting rod in the window curtain fixing device and the transmission button transmission device, the inclined block transmission device controls two or more inclined blocks to work by utilizing the principle of the connecting rod, and a hole fixed with the shell is formed right below each inclined block and is excessively matched with the pin of the shell. The button transmission device consists of a button and three connecting rods, when the button transmission device works, the transmission force of the button is transmitted to the connecting rods, and then the connecting rods transmit the inside force to the inclined block transmission device to drive the inclined block transmission device to work. When the paper curtain is pulled down, a button above the device is pressed, the button drives a connecting rod to work, the connecting rod below the device is transmitted by utilizing the lever principle, the connecting rod below the device pushes an inclined block transmission device to work, the inclined block transmission device slightly rotates around a matched shell pin, the connecting rod is arranged on the boundary of the inclined block, a plurality of inclined blocks can be driven to work simultaneously, the purpose of controlling the movement of a plurality of mechanisms is achieved, and at the moment, the curtain fixing device is popped out by a spring to play a role. When the work is finished, the design of the oblique block can enable the curtain fixing device to be buckled into the groove of the shell.

Furthermore, a notch for connecting the connecting rod is formed in the inner side of the shell, and a bayonet for connecting the fixing device and a pin for connecting the inclined block are arranged in the groove.

Furthermore, the left side and the right side of the curtain fixing device are both provided with cylinders for bayonet connection with the shell.

Furthermore, the arc-shaped groove used for fixing the curtain rod in the fixing device can be designed into a size according to the curtain rod to be fixed.

Furthermore, the bottom of the fixing device is provided with a groove for placing a fixing spring.

Furthermore, a connecting rod is arranged on the boundary of the inclined block transmission device and used for driving the plurality of inclined blocks to move simultaneously.

Further, the button transmission device is composed of a plurality of connecting rods, and force is transmitted by the connecting rods when the button transmission device works.

The utility model has the advantages that: the utility model discloses have a shell, the shell includes the round pin of fixed button and connecting rod inclined block, still has the hole of connecting fixing device simultaneously, carries out the during operation, only needs to press the button, and the button just can transmit power for the connecting rod, and the connecting rod transmits power for the inclined block again, thereby the inclined block makes fixing device pop out under the effect of its recess internal spring around the slight rotation of round pin on the shell, chooses for use simple structure, and the cost of manufacture is low. The fixing device for fixing the curtain rod is arranged in the groove of the shell, so that accidental injury by the hard fixing device can be effectively avoided, and accidents are effectively avoided. Meanwhile, the side of the oblique block is provided with the fixed connecting rod, so that the motion of the other oblique block can be controlled simultaneously, the motion of the two oblique blocks can be controlled simultaneously when the button is pressed, the work of the two devices can be completed simultaneously, and the device is more efficient. In addition, the slope design of sloping block makes things convenient for fixing device to retrieve after the work is accomplished, and convenient and fast still has certain aesthetic property simultaneously.
