Description

A kind of brake gear of hollow glass louver

Technical field

The utility model belongs to shutter technical field, is related to a kind of brake gear of hollow glass louver.

Background technology

Shutter refers to be equipped with the window of blinds, is generally used for indoor and outdoor sunshade, ventilation, and very beautiful.Hundred Leaf window is widely used, wherein just including applying the hollow glass louver in hollow glass, such shutter not only can be with Achieve the purpose that dim sunshade, can also preferably ensure privacy, also have and keep blinds clean for a long time, without clean excellent Point, and shape is also more beautiful, so as to obtain the favor of consumers in general.

Such as Chinese patent【Application number：201621236124.0】A kind of hollow glass of window with built-in louver is disclosed, including The window frame enclosed by upper side frame, boundary frame area and two frames, it is parallel in window frame to be equipped with hollow glass, it is set between hollow glass There is blind, the winding mechanism being connected with shutter is equipped in the upper side frame, is equipped in the frame and is connected with winding mechanism Control mechanism, the control mechanism include guide rail, magnet slide block and control line, the magnet slide block be mounted on guide rail in, institute Control line is stated with magnet slide block to be connected.Can sliding up and down for magnet slide block, magnet be controlled by magnet movable block when in use Sliding block drives bearing rotary while sliding up and down by control line, and shaft rotation, while traction rope are being driven by bearing Start to rotate, so that traction rope rises or falls, have the function that pull-up and put down blind.When encounter without using In the case of, individually magnet movable block can be removed and be put into side, avoid being knocked damage.

But there are following defects in use for the hollow glass of above-mentioned window with built-in louver：When magnet is removed or When person is because of unexpected come off, venetian blind can continue to glide up to putting down completely from original height under gravity, also It is to say, in the case that magnet is detached from window frame, venetian blind can not rest on original height, shutter be caused to use in this way It is extremely inconvenient to come.

Invention content

The purpose of this utility model is that there are the above problems for existing technology, it is proposed that a kind of hollow glass louver Brake gear, the utility model solve the technical issues of be how to prevent magnet be detached from window frame when shutter be affected by gravity and It glides.

The purpose of this utility model can be realized by following technical proposal：A kind of brake dress of hollow glass louver It puts, including housing and the sheave being arranged in housing, which is characterized in that be fixed with one-way-sleeve, the conductor rope in the housing Wheel is sleeved on one-way-sleeve, is surrounded on the peripheral surface of the one-way-sleeve in wavy guide slide, the guide slide There is the lock that one end is communicated with guide slide with trough portion, on the peripheral surface of the one-way-sleeve between two adjacent wave valley Determine slot, each lock slots each along one-way-sleeve circumferentially and extending direction is identical, have on the inner peripheral surface of the sheave Axially disposed sliding slot, the sliding slot is interior to be equipped with ball, and the ball can be rolled along guide slide.

The operation principle of the brake gear of this hollow glass louver is as follows：When shutter drawstring magnet slide block band During dynamic lower drop-down, sheave rotates forward at this time, and ball is located in guide slide at this time, and with the rotating forward of sheave, sliding slot is with rolling Pearl rolls in guide slide, that is to say, that at this point, sheave can be relatively rotated with one-way-sleeve, realizes the normal of curtain blade Lifting operations；When magnet is detached from window frame, for magnet slide block no longer by magnet magnetic-adsorption, drawstring is lost downward lead at this time Gravitation, such curtain blade can be influenced by gravity itself to decline, and sheave is from reversion is just changed at this time, by leading above Design to slot and lock slots, at this time ball slide along sliding slot and roll simultaneously to lock slots from guide slide, that is, It says, locked at this point, sheave is realized with one-way-sleeve, sheave can not be rotated further, allow for curtain blade in this way and no longer glide, So as to which shutter is affected by gravity and glides when magnet being prevented to be detached from window frame；In addition, when curtain needs to decline, although leading at this time Rope sheave does not turn, but by the way that magnet slide block is pushed to rise, and drawstring is not towed power and influences in relaxation state, in this way in curtain at this time The gravity of blade can be realized as declining.

In the brake gear of above-mentioned hollow glass louver, the lock slots communicate the notch of one end with guide slide Width is more than the width of guide slide and at the trough portion of corresponding side.By designing above, when sheave inverts, just Lock slots are rolled into ball, so as to ensure that sheave stalls, and then prevent shutter by gravity in time when magnet is detached from window frame It influences and glides.

There is fixed column in a tubular form in the brake gear of above-mentioned hollow glass louver, in the housing, it is described There is the opening extended along fixed column length direction, the fixed column on the peripheral surface of close end by having on the end of fixed column Limit card convex, the one-way-sleeve be set in fixed column and with fixed column tight fit, the limiting card cam is on one-way-sleeve.It is logical Cross above design so that one-way-sleeve is convenient and is reliably connected in fixed column, so that directive wheel is locked in one with one-way-sleeve One-way-sleeve is not in skid when rising, so as to which shutter is affected by gravity and glides when magnet being further prevented to be detached from window frame.

In the brake gear of above-mentioned hollow glass louver, the housing includes pedestal and cover, the fixed column On pedestal, there is connecting pole in the cover, the connecting pole be plugged in the fixed column and with fixed column tight fit. By more than matching design, slightly opened outward when fixed column can be squeezed in connecting pole insertion fixed column, so that fixed column With one-way-sleeve it is connected more securely, so that one-way-sleeve is not in skid when directive wheel and one-way-sleeve lock together, So as to which shutter is affected by gravity and glides when magnet being further prevented to be detached from window frame.

In the brake gear of above-mentioned hollow glass louver, one end of the sliding slot extends axially outwardly and penetrates through Sheave.By designing above, sliding slot and guide slide are fit into convenient for ball.

In the brake gear of above-mentioned hollow glass louver, on the sheave there is counterbore, have in the counterbore There is mounting hole, the sliding slot is located on the hole wall of mounting hole and one end is communicated with counterbore, has flange on the one-way-sleeve, described One-way-sleeve is threaded through in mounting hole, and the flange is resisted against the bottom of counterbore and keeps off outside sliding slot.By designing above so that rolling Pearl will not drop out after being installed in sliding slot, improve the reliability that this brake gear uses.

Compared with prior art, the brake gear of this hollow glass louver has the following advantages：This brake device structure Simply, easy to assembly, using reliable, shutter is affected by gravity and glides when can effectively prevent the magnet to be detached from window frame.
