Description
Technical Field
The invention relates to the technical field of household mosquito net devices, in particular to a support structure of a mosquito net.
Background
Some kinds of mosquito net supports are fixed on a ceiling by using a frame (hereinafter referred to as a top frame) of a mosquito net top structure as a bearing part of the mosquito net support, and no supporting pillar is needed, for example, the name of a utility model with a patent number of CN95213738.0 is 'lifting hidden type decorative mosquito net' and the name of a utility model with a patent number of CN96245927.5 is 'lifting type decorative mosquito net', besides, a small number of other kinds of top frames are fixed on the ceiling of the mosquito net without supporting pillars on the market, and the mosquito net has the advantages of being characterized in that: the supporting posts of the mosquito net are prevented from obstructing the movement and visually dividing the bedroom space, all supporting structures and decorations of the mosquito net can be mounted by attaching to the ceiling, and after getting up, the mosquito net curtain is lifted to the height close to the ceiling or horizontally moved to the position attached to the wall surface of the bedback, so that the mosquito net curtain does not occupy the moving space on the bed and cannot cause the crowded visual impression of the bedroom; the disadvantage of this kind of mosquito net is that, because the fabric part of the mosquito net (hereinafter referred to as "mosquito net cloth piece") needs to be removed and washed at regular time, and the mosquito net cloth piece is supported and hung on the frame of the top structure of the mosquito net (for example, CN96245927.5, has two layers of frames, the upper layer fixed on the ceiling is used for sticking and hanging the decorative curtain, and the mosquito net curtain and the mosquito net top cloth are supported and hung on the lower layer), so the user stands on the floor or bed surface and lifts up the hand, and is inconvenient to detach the mosquito net cloth piece, usually needs to ascend, thus there is the possibility of falling accident, and it is very inconvenient for the user who is small in courtesy and does not dare to ascend. Mosquito nets with top frames fixed on ceilings appear and are sold in the market for nearly 25 years, but no style of mounting and dismounting mosquito net cloth pieces without ascending heights is seen in the mosquito nets in the market at present, so that most of household mosquito nets sold in the market at present are of the type with the top support height of about 2 meters, and the technical scheme that no people invent and overcome the defects of the mosquito nets for a long time is disclosed. Thus, the prior art is in need of improvement and advancement.
Disclosure of Invention
The invention aims to overcome the defects of the mosquito net device with a top frame fixed on a ceiling, and provides a mosquito net support with a stranded cable wheel and capable of lifting, so that the top frame of the mosquito net can be fixed at a height which cannot be reached by a hand standing on the ground during daily use, a user can conveniently detach and mount mosquito net cloth pieces when standing on the floor, and the mosquito net support is convenient to detach and maintain parts at the top of the mosquito net.
The purpose of the invention is realized by the following technical scheme.
The technical scheme 1: the mosquito net support capable of lifting per se with the cable pulley comprises a top frame 6 and a set of pulley lifting mechanism capable of lowering or lifting the top frame 6 and locking the top frame at a height close to a ceiling 1, wherein the pulley lifting mechanism comprises at least three lifting cables 4, pulleys 2 with the same number, a cable pulley 8, a cable pulley 9, a cable 10 and a cable locker; the inhaul cable lock is composed of a lock shell 3 and a gear 3.1, the upper part of one side of the side surface of the inner cavity of the lock shell 3 is provided with an inward inclined tooth surface which is called a lock tooth surface 3.2, the vertical surface opposite to the lock tooth surface 3.2 is called a tooth surface opposite surface 3.3, the lock tooth surface 3.2 can be meshed with the tooth surface of the gear 3.1, the bottom surface of the inner cavity of the lock shell 3 is an inclined surface 3.4, the inclined surface 3.4 is shaped that one side close to the lock tooth surface 3.2 is lower and the other side close to the tooth surface opposite surface 3.3 is higher and is divided into two halves by a long hole which penetrates through up and down, the wheel periphery of the ropewheel 8 is provided with at least two grooves, and the diameter of the groove bottom of one groove is larger; the assembly relation is that the stranded cable wheel 8 is fixed on the ceiling 1 through the wheel shaft 8.1, the stayed cable wheel 9 is fixed on the ceiling 1 through the stayed cable wheel outer shell 9.1, the locking device shell 3 is fixed on the stayed cable wheel outer shell 9.1 below the stayed cable wheel 9, each lifting rope 4 is respectively connected with a hanging point of the top frame 6 and is connected to the groove bottom with smaller diameter of the stranded cable wheel 8 after being bent upwards to be horizontal through the wheel 2, one end of the stayed cable 10 is connected to the groove bottom of the groove with larger diameter of the groove bottom of the stranded cable wheel 8 and is wound in the groove with allowance, the other end of the stayed cable 10 horizontally enters the stayed cable wheel 9 and is bent downwards, and naturally hangs down after passing through the gap between the opposite surface 3.3 of the tooth surface of the locking device shell 3 and the gear 3.1, and.
The working principle of the technical scheme 1 is that a hand vertically pulls a guy cable 10 downwards, the guy cable 10 is pulled out from a guy cable wheel 8 and drives the guy cable wheel 8 to rotate, the rotating guy cable wheel 8 can simultaneously wind each lifting rope 4 into a groove, each hanging point of a top frame 6 is pulled and lifted by the lifting rope 4, the hand swings the guy cable 10 to a gear 3.1 of a guy cable locker at the moment, the gear 3.1 is meshed with a tooth surface 3.2 of the locker, the hand moves upwards, the hand-held guy cable 10 can also move upwards and still be tensioned under the action of the gravity of the top frame 6, the guy cable 10 tensioned in the locker shell 3 can move upwards and rub the gear 3.1 to roll upwards, the gear 3.1 rolling upwards can immediately press the tooth surface of the guy cable 10 to the opposite 3.3 under the guidance of the tooth surface 3.2 of the locker, and the guy cable 10 is locked and locked; then, the hand pulls the cable 10 vertically downwards, the gear 3.1 falls on the bottom inclined surface 3.4 of the locking device and rolls to the side away from the cable 10 (shown by a dotted line gear 3.1 in fig. 2), and at the moment, the cable 10 keeps moving vertically upwards and cannot touch the gear 3.1 and be locked by the gear 3.1, so that the top frame 6 can be smoothly dropped to the required height; in daily use, the top frame 6 is raised and locked at a height against the ceiling 1, and the falling guy cable 10 can be manually wound into a coil and hung on the top cloth of the mosquito net or on the hook 6.1 by means of a tool.
Improved technical scheme 2: on the basis of the technical scheme 1, a spring buffer is connected between a lifting point of a lifting rope 4 and a top frame 6, the spring buffer is composed of buffer shells 7 and compression springs 7.1, each buffer shell 7 is fixedly connected to one lifting point of the top frame 6, the lifting rope 4 downwards penetrates through the buffer shells 7 and the compression springs 7.1 arranged in the buffer shells, and the compression springs 7.1 are connected below the compression springs 7.1.
The working principle is that the elasticity of the lifting rope 4 is loosened, the required movement of the gear 3.1 is locked, the top frame 6 is enabled to fall back by 0.5-2 cm after being contacted with the ceiling 1, if the compression spring 7.1 of the scheme is compressed after the top frame 6 is contacted with the ceiling 1, the compression spring 7.1 can push the top frame 6 to the height of being attached to the ceiling 1 after the inhaul cable 10 is locked.
When the lengths of the drooping lengths of the lifting ropes 4 are different, the part of the top frame 6 hung by the shorter lifting rope 4 firstly hits the ceiling 1 when being lifted, so that other hanging points hung by the longer lifting ropes 4 are limited to be lifted continuously, the heights of the hanging points of the top frame 6 are different and cannot be integrally stuck to the ceiling 1, and due to the spring buffer, the lifting rope 4 can be lifted continuously until the compression spring 7.1 is compressed after the part of the top frame 6 hung by the shortest lifting rope 4 hits the ceiling 1, so that the part of the top frame 6 hung by the other relatively longer lifting ropes 4 can be lifted continuously, and the difference between the lower-hanging lifting rope 4 and the lifting rope 4 with the longest drooping is smaller than the compression stroke of the compression spring 7.1, so that the whole part of the top frame 6 hung by each lifting rope 4 can reach the height of the ceiling 1.
Improved technical scheme 3: on the basis of the technical scheme 1, the rope winding device 5 is further arranged, a spring and a winding shaft connected with the spring are arranged in the rope winding device 5, one end, which is operated by a human hand, of the stay rope 10 is connected with the winding shaft of the rope winding device 5, and the stay rope 10 can be automatically wound into the rope winding device 5 through the elastic force of the spring of the rope winding device 5. The cord retractor 5 is constructed and functions like a commercially available tape measure that automatically retracts the tape into the housing by virtue of the spring force of a winding spring, except that the pull cord 10 replaces the tape of the tape measure. The working principle is that after the top frame 6 is lifted, the cable 10 is automatically retracted into the cable winder 5, the elasticity of the spring is enough to lift the cable winder 5 to the height close to the ceiling 1, and the cable 10 can not hang down to hinder the movement.
