Problems solved by technology

[0002] In order to maintain the sound insulation effect of the traditional soundproof door, cement is injected into the door body, so that the door body is thick, inconvenient to open and close, and the hinge is easily damaged, but the sound insulation effect is not ideal, mainly because there is a gap between the door body and the door frame. For this reason, rubber sealing strips are often used to seal the gap around the door body.
However, due to the different widths of the gap between the door body and the door frame and the repeated extrusion of the rubber sealing strip is easily broken and damaged, the sealing and sound insulation effect of the soundproof door is still not good

Embodiment 1

[0028] Embodiment 1: as Figure 1 to Figure 6 As shown, a top-pressure soundproof door includes a hinge 1 and a door frame sealing strip, wherein:

[0029] Door frame body 2: the inner side of the front end surface of the door frame body forms an L-shaped angle to form a door card slot 20 . The door frame body inside the corner of the door card slot is provided with a sealed chamber 24, and the sealing opening 21 of the sealed chamber is located at the corner of the door card slot. The front end faces of many rubber sound-insulating blocks 3 connected in series protrude from the sealing opening in the slot of the door. The rear part of the rubber sound-insulating block is located in the sealed chamber, and a top pressure spring 23 is arranged between the rear end surface of each rubber sound-insulated block and the rear end surface of the corresponding sealed chamber. The door frame body can be made of aluminum profiles.

[0030] Rubber sound-insulating block 3: it is a str...

Embodiment 2

[0037] Embodiment 2: as Figure 1 to Figure 6 As shown, a top-pressure soundproof door includes a hinge 1 and a door frame sealing strip 29, wherein:

[0038]Door frame 2: The door frame is composed of a main frame 25 , an inner frame 212 and an outer frame 26 . The main frame is located at the front side of the door frame, the inner frame is located at the inner side of the door frame, and the outer frame is located at the outer side of the main frame and the inner frame. The rear end of the main frame and the front end side of the inner frame body are connected into one body through several second bolts 210 . The inner side of the outer frame is integrated with the outer side of the main frame and the inner frame through several first bolts 28 . The two ends of the outer frame body can be provided with screw holes 27, so as to facilitate the integration with the corresponding wall door opening by bolts. The front end of the inner frame is arranged in the middle of the inn...

Abstract

The invention discloses a top pressing type sound-proof door which comprises a hinge and a door frame sealing strip, wherein sealing chambers are formed in a door frame body on the inner side of a door clamping groove angle; the sealing openings of the sealing chambers are formed in the door clamping groove angle; the front end faces of a plurality of rubber sound-proof blocks connected with eachother stretch out of the sealing openings and are positioned in a door clamping groove; the rear parts of the rubber sound-proof blocks are positioned in the sealing chambers; a top pressing spring isarranged between the rear end face of each of the rubber sound-proof blocks and the rear end face of the corresponding sealing chamber; the door frame body is made of aluminium profile; the front endface of each of the rubber sound-proof blocks is an external protruding arc-shaped surface; the outer side edge of a door body is positioned in the door clamping groove of the door frame; and the external protruding arc-shaped surface, corresponding to the front end face of each of the rubber sound-proof blocks, on the inner side circumference of the door body is provided with an indent arc-shaped side. The top pressing type sound-proof door can greatly improve the sealing and sound-proof effect of the sound-proof door and has the advantages of being reasonable in structural design, light indoor body weight, easy to open and close, excellent in sealing and sound-proof effect, long in service life and low in preparation cost.

Description

technical field [0001] The invention belongs to a top-pressure soundproof door. Background technique [0002] In order to maintain the sound insulation effect of the traditional soundproof door, cement is injected into the door body, so that the door body is thick, inconvenient to open and close, and the hinge is easily damaged, but the sound insulation effect is not ideal, mainly because there is a gap between the door body and the door frame. For this reason, rubber sealing strips are often used to seal the gap around the door body. However, because the width of the gap between the periphery of the door body and the door frame is different, and the repeatedly extruded rubber sealing strip is easily broken and damaged, the sealing and sound insulation effect of the soundproof door is still not good. Contents of the invention [0003] The purpose of the present invention is to provide a top-pressure soundproof door, which can greatly improve the sealing and soundproofing ...
