Description

Technical Field

[0001] The utility model relates to the technical field of edge binding structures, in particular to an edge binding structure for a soundproof door leaf. Background Art

[0002] Soundproof doors are mainly used in places with high sound insulation requirements. The door leaf is mainly made of new galvanized steel plates, and professional sound insulation materials, damping sound insulation boards and sound insulation cotton are used as sound insulation fillers. At the same time, the most important thing about soundproof doors is the sealing treatment. The use of magnetically controlled sealing can ensure good sealing. The existing soundproof door leaf edge wrapping structure (Announcement No.: CN214062790U) has the following disadvantages in use:

[0003] During use, when the first edging and the second edging need to be disassembled, the two push rods in the second edging need to be pushed at the same time to shrink the sealing block and the first spring so that the first edging and the second edging are no longer fixed. For doors of larger sizes, it is troublesome for one person to operate and requires the help of other staff. For this reason, this patent proposes a soundproof door leaf edging structure to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a soundproof door leaf edge wrapping structure to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soundproof door leaf edging structure, including a door body, a first edging inserted at the top and bottom of the door body, a second edging inserted at both sides of the door body, a connecting groove is opened inside the first edging, and slots are opened at both ends of the second edging, a double-headed screw is rotatably connected between the two ends of the connecting groove, and sliders are screwed on the outer walls of both ends of the double-headed screw, a limit rod is fixed between the two ends of the connecting groove, the limit rod passes through the slider, and two extrusion blocks that move up and down are slidably connected to the two ends of the connecting groove, the top of the slider contacts the bottom end of the extrusion block, a spring is fixed between the connecting groove and the extrusion block, an insert block is fixed on the top of the extrusion block, the insert block is inserted in the slot, and two fixing plates are fixed in the connecting groove for limiting the slider.

[0006] Preferably, a second bevel gear is fixed to the outer wall of the double-headed screw, a rotating rod is rotatably connected inside the first edge, a first bevel gear is fixed to the outer wall of the rotating rod, and the first bevel gear is meshed with the second bevel gear.

[0007] Preferably, one end of the rotating rod passes through the first edge and a knob is fixed to the outer wall thereof, the knob is located on the back side of the door body, and a handle is installed on the front side of the door body.

[0008] Preferably, two slide grooves are provided in the connecting groove, a connecting block is fixed to one end of the extrusion block, and the connecting block slides in the slide groove.

[0009] Preferably, second connecting rods are fixed on both sides of the door body, and the second edging is inserted into the outer wall of the second connecting rod.

[0010] Preferably, a first connecting rod is fixed to the top and bottom ends of the door body, the first connecting rod is T-shaped, and the first edging is plugged into the outer wall of the first connecting rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By turning the knob, the knob drives the rotating rod to rotate, and the rotating rod adjusts the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate, thereby causing the double-headed screw to rotate. The rotation of the double-headed screw drives the two sliders to move in the directions away from each other, so that the slider squeezes the squeezing block, so that the squeezing block slides in the connecting groove, thereby driving the spring to compress, so that the plug block is inserted in the slot to fix the second edge package, thereby realizing the fixation of the first edge package and the second edge package. In addition, when the first edge package and the second edge package need to be disassembled, the two sliders are moved in the directions close to each other by rotating the knob in the opposite direction, and the fixed plate limits the slider so that the slider can only move to the fixed plate position. When the slider moves, the spring drives the squeezing block to move, so that the plug block moves out of the slot and no longer limits and fixes the second edge package, so that the first edge package and the second edge package can be removed. Its installation and disassembly are relatively convenient and do not require the cooperation of multiple people. BRIEF DESCRIPTION OF THE DRAWINGS

The door panels are mainly formed with new galvanized steel plates, and professional sound insulation materials, damping sound insulation panels and sound insulation cotton are used as sound insulation fillers inside. At the same time, the most important thing about soundproof doors is the sealing treatment. The soundproof door panel edging structure provided by the utility model is installed on the outside of the soundproof door panel, and it is easy to disassemble. When the edging is damaged in the later stage, it can be replaced, which is more convenient.

[0023] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: a soundproof door leaf edging structure, comprising a door body 1, a first edging 2 is inserted at the top and bottom of the door body 1, and a second edging 3 is inserted at both sides of the door body 1, a connecting groove 5 is opened inside the first edging 2, and slots 6 are opened at both ends of the second edging 3, a double-headed screw rod 7 is rotatably connected between the two ends of the connecting groove 5, and sliders 8 are screwed on the outer walls of both ends of the double-headed screw rod 7, and a limiting rod 13 is fixed between the two ends of the connecting groove 5, and the limiting rod 13 passes through the slider 8, and the limiting rod 13 limits the slider 8 so that the slider 8 can only move left and right, and two extrusion blocks 14 that move up and down are slidably connected to the two ends of the connecting groove 5, and the top of the slider 8 contacts the bottom end of the extrusion block 14, a spring 16 is fixed between the connecting groove 5 and the extrusion block 14, and an insert block 15 is fixed at the top of the extrusion block 14, and the insert block 15 is inserted in the slot 6, and two fixing plates 9 are fixed in the connecting groove 5 for limiting the slider 8. The outer wall of the double-headed screw 7 is fixed with a second bevel gear 12, the first edge 2 is rotatably connected with a rotating rod, the outer wall of the rotating rod is fixed with a first bevel gear 11, and the first bevel gear 11 is meshed with the second bevel gear 12. One end of the rotating rod passes through the first edge 2, and a knob 4 is fixed to its outer wall. The knob 4 is located on the back of the door body 1, and a handle is installed on the front of the door body 1. Two slide grooves 10 are provided in the connecting groove 5, and a connecting block is fixed to one end of the extrusion block 14, and the connecting block slides in the slide groove 10.

[0024] When the slider 8 moves, the spring 16 drives the extrusion block 14 to move, so that the plug block 15 moves out of the slot 6 and no longer limits and fixes the second edge wrapping 3, thereby the first edge wrapping 2 and the second edge wrapping 3 can be removed.
