Description

Hand-operated arm-opening type window opener for casement window

Technical Field

The utility model relates to the technical field of buildings, in particular to a hand-operated arm-spreading type window opener for a casement window.

Background

In traditional window design, opening and shutting of window mostly is manual push-and-pull opening and shutting, but in a lot of window use scenes, the barrier can be placed to the window next door, for example the window in kitchen can be placed on the top of a kitchen side mostly, when needing switch window, the user often need bend over in the past push-and-pull window, and it is very inconvenient to operate, and can not the wide-angle window of opening, reduces ventilation effect.

The applicant and 2021, 24.3.8 apply for a Chinese utility model with patent number 202120601754.8, and disclose a window-pushing assistor, which makes the window-pushing swing rod and the output push rod always parallel by forming a quadrilateral linkage structure at the hinged ends of the first support rod, the second support rod and the output push rod, and utilizes the instability of the quadrilateral structure, i.e. the included angle of the window-pushing swing rod, the first support rod, the second support rod and the output push rod can still change after the lengths of the four sides of the window-pushing swing rod, the first support rod, the second support rod and the output push rod are fixed, and utilizes the characteristic to make the window-pushing telescopic mechanism realize the characteristics of deformation, flexible stroke, etc., thereby conveniently solving the problems of insufficient window-opening angle and troublesome window opening and closing, and simultaneously, the quadrilateral linkage structure can not be exposed too much in the closed state, and the product aesthetic property is improved, but in the actual use process, the force is consumed on the linkage rod when the window is opened, the four-bar linkage cannot be used better, but the four-bar linkage is easy to bend and has larger friction force, so that the torsion is larger when the four-bar linkage is hand-operated, and the structure of the four-bar linkage is too complex and the cost is high.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a hand-operated arm-opening type window opener for a casement window, aiming at the defects of the prior art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a hand exhibition arm formula ware of windowing of flat-open window, is including installing the PMKD on the window frame and installing the casement mounting on the casement, be equipped with on the PMKD and push away window pendulum rod, its characterized in that: one end of the window pushing swing rod is connected with the driving assembly, the other end of the window pushing swing rod is provided with an output push rod, one end of the output push rod is hinged with the window sash fixing piece, the other end of the output push rod is hinged with the window pushing swing rod, when the angle of the window sash is 0 degree, the window pushing swing rod is overlapped with the output push rod, and when the angle of the window sash is 90 degrees, the window pushing swing rod and the output push rod form a straight line.

Adopt above-mentioned technical scheme, through installation PMKD on the window frame, the last setting of PMKD pushes away the window pendulum rod that is driven by drive assembly, make to push away the window pendulum rod and promote the casement and open and shut, because the length of pushing away the window pendulum rod influences the angle that the casement opened and shut, so set up the output push rod between window pendulum rod and casement mounting, when waveing the ware of windowing promptly, moment is through pushing away the window pendulum rod and transmitting the output push rod, the output push rod makes circular-arc motion along with the window, thereby open, close the same reason, the originated hard problem of four connecting rods originally has been solved to this structure, compare again and make its structure simpler and with low costs under the condition that four connecting rod structure guarantees wide-angle windowing again, it is more convenient to use.

Foretell hand exhibition arm formula ware of windowing of flat-open window can further set up to: the hinged end of the output push rod and the window pushing swing rod is provided with a limiting baffle, the limiting baffle is arranged at one end, facing the window sash, of the output push rod, when the angle of the window sash is 0 degree, the limiting baffle is abutted to the front end of the output push rod, and when the angle of the window sash is 90 degrees, the limiting baffle is abutted to the rear end of the output push rod.

Adopt above-mentioned technical scheme, make the casement under the closure state through setting up limit baffle, limit baffle and output push rod front end butt avoid the casement closure state under the swing, under the biggest open mode of casement, limit baffle and output push rod rear end butt avoid the excessive displacement of output push rod, lead to the casement to be in the most greatly reduced angle that contracts after the open mode, promote product stability.

Foretell hand exhibition arm formula ware of windowing of flat-open window can further set up to: the driving assembly comprises a turbine shaft arranged on the fixing base plate, a worm meshed with the turbine shaft and a hand crank driving the worm to rotate, and the window pushing swing rod is fixedly connected with the turbine shaft through a connecting piece and driven to swing by taking the turbine shaft as a fulcrum through the hand crank.

By adopting the technical scheme, the hand crank drives the sliding window swing rod to swing through the turbine worm, so that the window swing rod has a larger transmission ratio, is compact in structure, stable in transmission and free of noise, and meanwhile, the kinetic energy of the obliquely arranged worm can be transmitted to the horizontal turbine shaft through the vortex worm, so that the hand crank can conveniently apply force.

Foretell hand exhibition arm formula ware of windowing of flat-open window can further set up to: the fixed base plate is provided with a gear shaft installation cavity for installing a turbine shaft and a worm installation cavity for installing a worm, bearings are arranged at two ends of the turbine shaft corresponding to the gear shaft installation cavity, and a movable notch for swinging the push window swing rod is arranged at the position of the fixed base plate corresponding to the gear shaft installation cavity.

By adopting the technical scheme, the gear shaft mounting cavity and the worm mounting cavity are arranged, so that the internal parts of the window opener cannot deviate in the using process, the friction coefficient and the noise of a transmission load are reduced by arranging the bearing, and the swing angle of the window pushing swing rod is limited by arranging the movable notch.

Foretell hand exhibition arm formula ware of windowing of flat-open window can further set up to: the crank is including connecting seat, rocking arm and rocking handle, the connecting seat passes through fastener and worm fixed connection, the rocking arm passes through the articulated elements and is articulated mutually with the connecting seat, makes the rocking arm can pass through the articulated elements and changes application of force direction, the rocking handle is articulated mutually with the rocking arm.

By adopting the technical scheme, the rocking handle is hinged with the rocking arm, and the rocking arm is hinged with the connecting seat, so that when a user drives the window opener to work by hand, the user can adjust the rocking handle according to different window sash scenes by changing the force application direction of the rocking arm, and the operation is more convenient.

The utility model is further described below with reference to the accompanying drawings.
