The purpose of the utility model is to provide a kind of closed type hollow glass louvers, and which solve existing hollow blinds Windowpane the problem of sealing performance is not good, have the advantages that improve the sealing performance of hollow louver glass window.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of closed type hollow glass louver, including frame, the glass inner sheet, the blinds that are set in turn in the frame Curtain and glass outer plate are provided with mounting hole on the frame, are equipped in the mounting hole and the venetian blind is driven to turn over leaf Rotary components, be provided with seal assembly between the mounting hole and the rotary components；The seal assembly includes rotating ring, quiet Ring, rubber standoff, spring base, elastic component, baffle ring, the rubber standoff include the neck of both head envelope portion, axis part and connection； Two axial end faces of the rotating ring are abutted with the axial end face of the axial end face of the stationary ring and head envelope portion respectively；The bullet Spring abutment is tightly sleeved outside head envelope portion, and the spring base is connected to inner wall and the head envelope portion of the mounting hole Axial end face；The elastic component is sheathed on the outside of the spring base, and one end of the elastic component, which abuts, is fixed on the spring On seat, the other end be fixed on the axial end face of the baffle ring.

Using the above scheme, for the seal assembly being installed, baffle ring is pressurized close to spring base, and elastic component is pressurized Shorten the precompression that generates to spring base, made between spring base and rubber standoff with this, between rubber standoff and rotating ring, rotating ring All keep enough between mounting hole between stationary ring, between stationary ring and interstage sleeve and where interstage sleeve and seal assembly installation Precompression improves the sealing performance of hollow louver glass window to form good seal combination；In rubber standoff and rotating ring When with knob, knob vibration is tightly sleeved the axis part on knob since pre- deformation can provide compensation, is turning Axis part is abutted with knob always during dynamic, to can generate compensation between centers compensation to vibration always.

Further preferably are as follows: the venetian blind includes left terraced rope, right ladder is restricted, multiple be arranged side by side is restricted in the left ladder Louvre blade；The end of the left ladder rope and the right ladder rope is fixed on the rotary components, described in the rotary components control Left ladder rope is opposite with the right ladder rope to be moved up and down.

Using the above scheme, it by controlling rotary components, realizes and is moved down on opposite between the left ladder rope of control and right ladder rope Dynamic purpose, so that the left and right overturning of louvre blade is controlled, the final purpose for realizing control venetian blind opening and closing.

Further preferably are as follows: the accommodating chamber for being connected to the mounting hole is provided in the frame, the rotary components include The knob that is plugged in the mounting hole, the end for being relatively fixed to the knob and the left bar being located in the accommodating chamber and the right side Bar, the pulley for being rotationally connected with the glass inner sheet and the outer on piece of the glass, one end of the knob is pierced by the frame Outside, the other end be located in the accommodating chamber, the left ladder rope is around on the pulley and the left bar is fixed in one end On, the right ladder rope is around on the pulley and one end is fixed on the right bar.

Using the above scheme, it by turning knob, can be realized opposite upper between the left end of left bar and the right end of right bar Lower movement, that is, can control it is left ladder rope it is right ladder rope between it is opposite move up and down, thus control louvre blade left and right overturning, finally Realize the purpose of control venetian blind opening and closing.

Further preferably are as follows: protrusion is provided with locking level on the left bar and the right bar, and the baffle ring is fixed on institute The inner wall of frame is stated, the baffle ring is provided with annular groove away from the axial end face of the elastic component, and the axis of the annular groove is inside Wall, which is circumferentially recessed, is provided with multiple shrinkage pools；When the locking level is plugged in the shrinkage pool, the axial end face of the rotating ring is supported It is connected to the axial end face of the stationary ring.

Using the above scheme, to be able to maintain venetian blind in the state opened or closed, in the axial end face of baffle ring Shrinkage pool is set and forces locking level to be embedded in shrinkage pool using the precompression of elastic component, to limit the rotation of knob；Work as needs It when changing the state of venetian blind, moves axially knob and rotates, so that locking level is detached from shrinkage pool.

Further preferably are as follows: the outer wall of the axis part is provided with the locating slot of annular indent, close in the mounting groove It is arranged with interstage sleeve, the outer wall of the interstage sleeve abuts the inner wall for being fixed on the spring base.

Using the above scheme, when knob moves axially, rotating ring does not abut mutually with the family of stationary ring, passes through mounting hole, bullet Compression between spring abutment, interstage sleeve, axis part and the bearing surface of knob realizes being slidingly sealed between knob and the gap of mounting hole Structure, to guarantee sealing effect.

Further preferably are as follows: the internal diameter of the interstage sleeve is less than the outer diameter of axis part, and the interstage sleeve forces the axis part Inner wall is connected to the outer wall of the knob.

Using the above scheme, it when baffle ring is pushed near spring base and the end abutment of axis part, avoids directly It abuts to spring base and rubber standoff is caused to generate deflection.

Further preferably are as follows: the outer wall of the neck and outer wall of axis part is at an acute angle is obliquely installed.

Using the above scheme, when carrying out installation operation to spring base and rubber standoff, the presence of neck can make Rubber standoff generate it is a degree of inwardly curve so that spring base may be mounted on mounting groove.

Further preferably are as follows: the rotating ring is embedded in the spring base, and the circumferential direction of the rotating ring is provided with spin-ended slot, institute The end for stating spring base is recessed the limit terminal cooperated with the spin-ended slot.

Using the above scheme, limit terminal be usually spring base be socketed on rotating ring after using tool to spring base into Row local deformation allows rotating ring stable and spring base and other assemblies is fixed to be caught in spin-ended slot.

Further preferably are as follows: the inner wall of the mounting hole, which is fixed with, to be tightly sleeved in the retaining ring of the outside of the stationary ring, institute The axial end face for stating stationary ring is connected on the retaining ring.

Using the above scheme, the axial compressive force of rotating ring transmitting stationary ring is finally born by retaining ring, so that the load of stationary ring is reduced, The final service life for extending stationary ring, guarantees the sealing effect of component.

In conclusion the utility model has the following beneficial effects:

1. by setting seal assembly, so that enough precompressions are all kept between each bearing surface, to be formed good Seal combination, so as to improve the sealing performance of hollow louver glass window；

2. providing between centers using the pre- deformation of rubber standoff to compensate, the leakproofness of hollow louver glass window is further increased Energy.
