Technical Field

[0001] The utility model relates to the technical field of silent door components, in particular to a sound-insulating and shock-absorbing cover shell for a silent zipper door. Background Art

[0002] Silent zipper door is a fast rolling door, which means the door runs faster than 0.6 meters. Its main function is to quickly isolate, so as to ensure the dust-free level of workshop air quality. It has many functions such as heat preservation, cold preservation, insect prevention, windproof, dust prevention, sound insulation, fire prevention, odor prevention, lighting, etc., and is widely used in food, chemical, textile, electronics, supermarket, refrigeration, logistics, warehousing and other places.

[0003] The current silent zipper door only reduces noise by using silent gears, but the noise isolation generated by the collision between the roller and the rolling door during the rolling process is relatively limited. It is simply a cover shell set on the outside, but the traditional cover shell adopts a rigid connection method, resulting in limited sound insulation and noise reduction effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the current silent zipper door only reduces noise by adopting silent gears and arranging a cover shell on the outside, and the noise isolation is relatively limited.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a sound insulation and shock absorption cover shell for a silent zipper door, comprising a top frame installed on the top of the door frame, the top corner positions inside the top frame are fixedly equipped with inner angle mounting seats, the interior of the top frame is elastically equipped with a horizontal box for accommodating the silent rolling door body through an extrusion spring on the inner angle mounting seat, circular assembly through holes are symmetrically provided on both side walls of the horizontal box, a bottom loading and unloading port is provided on one side of the lower end of the horizontal box, an inner elastic extrusion guide device is elastically equipped on the inner side surface of the horizontal box located on one side of the bottom loading and unloading port, and a sound insulation cotton component for improving the sound insulation effect is fixedly equipped on the inner side surface of the horizontal box.

[0006] The outer side surface of the horizontal box body corresponds to the position of the inner angle mounting seat and has a lateral assembly seat protruding outward. The inner angle mounting seat and the lateral assembly seat are both installed with locking bolts. The two ends of the extrusion spring are respectively inserted into the inner angle mounting seat and the lateral assembly seat and fixedly assembled with the locking bolts.

[0007] The inner side surface of the horizontal box body is located at one side of the bottom loading and unloading port and is provided with an arc-shaped assembly frame for installing an inner elastic extrusion guide device.

[0008] The inner elastic extrusion guide device comprises an arc-shaped fixing seat bolted to the inner side of the arc-shaped assembly frame, a flip arm movably mounted on the arc-shaped fixing seat, an extrusion roller movably mounted on the flip arm, and an extrusion spring.

[0009] The inner angle mounting seat and the lateral mounting seat are both provided with lateral limiting blind holes at the assembly ends of the extrusion springs.

[0010] The side wall of the arc-shaped assembly frame is provided with a lateral shrinkage frame for improving the stability of the arc-shaped fixing seat.

[0011] The beneficial effects of the utility model are:

[0012] (1) The sound-insulating and shock-absorbing cover for a silent zipper door of the utility model is connected to the top frame by an elastic assembly method, which can improve shock absorption and protection while achieving sound insulation and noise prevention;

[0013] (2) By elastically assembling an inner elastic extrusion guide device on the inner side of the horizontal box body at the side of the bottom loading and unloading port, the friction and guiding performance of the rolling door when rolling and unrolling can be reduced;

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Figure 1 and Figure 2A soundproof and shock-absorbing cover for a silent zipper door is shown, comprising a top frame 1 installed on the top of the door frame, wherein the top corners of the top frame 1 are fixedly mounted with inner angle mounting seats 2, and a horizontal box 4 for accommodating the silent rolling door body is elastically mounted inside the top frame 1 through an extrusion spring 3 on the inner angle mounting seat 2, and circular assembly through holes are symmetrically provided on both side walls of the horizontal box 4, and a bottom loading and unloading port 5 is provided on one side of the lower end of the horizontal box 4, and an inner elastic extrusion guide device is elastically mounted on the inner side surface of the horizontal box 4 located on one side of the bottom loading and unloading port 5, and a sound insulation cotton component 6 for improving the sound insulation effect is fixedly mounted on the inner side surface of the horizontal box 4.

[0021] The sound insulation cotton component 6 uses the sound insulation cotton of the prior art as the main raw material, and plays the role of sound insulation and noise reduction by sticking on the inner side of the bedroom box 4.

[0022] In order to facilitate assembly, the outer side of the horizontal box body 4 has a lateral assembly seat 7 protruding outward at the position corresponding to the inner angle mounting seat 2, and locking bolts 8 are installed inside the inner angle mounting seat 2 and the lateral assembly seat 7. The two ends of the extrusion spring 3 are respectively inserted into the inner angle mounting seat 2 and the lateral assembly seat 7 and fixed to the locking bolts 8.

[0023] A transverse assembly frame matching with the locking bolt 8 is welded and fixed at both ends of the extrusion spring 3. The locking bolt is limited by the screw section passing through the transverse assembly frame, and the threaded locking and fixing is performed by threading the locking nut on the outer side of the screw section at the protruding end.

[0024] In order to cooperate with the lateral installation, the inner side surface of the horizontal box body 4 located at the side of the bottom loading and unloading opening 5 has an arc-shaped assembly frame 9 for installing the inner elastic extrusion guide device.

[0025] In order to cooperate with the elastic extrusion, the inner elastic extrusion guide device includes an arc-shaped fixing seat 10 bolted to the inner side of the arc-shaped assembly frame 9, a flip arm 11 movably mounted on the arc-shaped fixing seat 10, an extrusion roller 12 movably mounted on the flip arm 11 and an extrusion spring 13.

[0026] The arc-shaped fixing seat 10 is inserted from the outer opening of the arc-shaped assembly frame 9 and then fixed and assembled by bolts. Then the flip arm 11 is inserted into the mounting hole inside the arc-shaped fixing seat 10 through the mounting shafts on both sides of the connecting end and is movably connected to the arc-shaped fixing seat 10. One end of the extrusion spring 13 is fixed on the inner side of the arc-shaped fixing seat 10, and the other end extrudes the flip arm 11 outward. In this way, the flip arm 11 is controlled to be extruded toward the bottom loading and unloading port 5, so that no friction or collision will be generated between the two sides of the rolling shutter door body and the bottom loading and unloading port 5, and the fit between the rolling shutter door body and the scroll shaft can be improved.

[0027] In order to cooperate with lateral assembly and improve the lateral bending resistance of the extrusion spring 3, lateral limiting blind holes 14 are opened on the inner angle mounting seat 2 and the lateral assembly seat 7 at the assembly end of the extrusion spring 3.

[0028] In order to improve the outer limiting capability after assembly, a lateral shrinkage frame 15 for improving the stability of the arc-shaped fixing seat 10 is provided on the side wall of the arc-shaped assembly frame 9 .

[0029] The lateral shrinkage frame 15 is provided with a locking screw hole, and the bolt is screwed into the locking screw hole to fix the arc-shaped fixing seat 10 inside the arc-shaped assembly frame 9.
