Description

Technical Field

[0001] The utility model relates to the technical field of automatic door tracks, and more specifically to a fixing structure for automatic door tracks capable of preventing vibration and reducing noise. Background Art

[0002] Automatic door refers to a control unit that can recognize the action of a person approaching the door (or some kind of entry authorization) as a signal to open the door, open the door through the drive system, and automatically close the door after the person leaves. The system controls the opening and closing process. It is divided into: revolving doors, curved doors, sliding doors, induction electric doors, emergency evacuation sliding doors, overlapping doors, folding doors, 90-degree push-open doors, fast doors and other categories.

[0003] When installing an automatic door, a track is needed to limit the movement of the automatic door. In order to reduce the noise and vibration when the automatic door is opened and closed, a rubber pad is generally installed inside the automatic door track to achieve the function of shockproofing and noise reduction. However, in actual use, the existing rubber pads lack a corresponding fixing mechanism. Simply relying on the friction between the rubber pad and the automatic door track cannot ensure the stability of the rubber pad, which will cause the rubber pad to move and fall off during use. Therefore, improvement is needed. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figures 1 to 12 As shown, the utility model provides a fixing structure for automatic door track vibration prevention and noise reduction, including:

[0036] Track 1, the inner movable sleeve at the bottom of track 1 is provided with a rubber pad 2;

[0037] A fixing mechanism 3, the fixing mechanism 3 is arranged inside the track 1;

[0038] A locking mechanism 4, which is arranged at the bottom end of the track 1;

[0039] Among them, the fixing mechanism 3 includes a pointed clamping block 301, which is movably installed at the bottom end of the rubber pad 2. The bottom end of the pointed clamping block 301 penetrates the track 1 and extends to the inside of the track 1 and is fixedly installed with a connecting plate 302. The outer surface of the connecting plate 302 is movably sleeved with the inner surface of the bottom end of the track 1. A connecting rod 303 is hinged at the middle of the bottom end of the connecting plate 302. The other end of the connecting rod 303 is hinged with a rectangular block 304. The rectangular block 304 is movably sleeved at the lower left bottom of the inner surface of the bottom end of the track 1. A first spring 305 is fixedly installed at the left end of the rectangular block 304. The other end of the first spring 305 is fixedly connected to the left inner wall of the bottom end of the track 1. The rectangular block 304 will move the pointed clamping block 301.

[0040] Since the first spring 305 is in a compressed state, the first spring 305 will generate a rightward force on the rectangular block 304 under the restoring action of the first spring 305, so that the rectangular block 304 is forced to move to the right with the bottom end of the connecting rod 303, and since the top end of the connecting rod 303 and the bottom end of the connecting plate 302 are hinged, the top end of the connecting rod 303 will generate an upward thrust on the connecting plate 302 under the action of the rectangular block 304, pushing the connecting plate 302 to move upward with the pointed block 301, so that the pointed block 301 and the rubber pad 2 are tightly fitted, thereby fixing the rubber pad 2.

[0041] Wherein, the locking mechanism 4 includes:

[0042] The limit block 401 is fixedly mounted on the left side of the bottom end of the rectangular block 304. The outer surface of the limit block 401 is movably connected to the inner surface of the bottom end of the track 1. A slide groove 402 is provided at the bottom end of the limit block 401. A long rod 403 is movably connected to the inner surface of the slide groove 402.

[0043] The T-shaped slot 404 is opened on the left side of the bottom end of the track 1 and is located below the first spring 305 . The right side of the inner surface of the T-shaped slot 404 is movably connected to the bottom of the outer surface of the long rod 403 .

[0044] When the long rod 403 is pushed horizontally, the long rod 403 will move to the left along the inner surface of the T-slot 404 with the limit block 401 and the rectangular block 304. When the long rod 403 moves to the left end inside the T-slot 404, the long rod 403 is pushed longitudinally to move the long rod 403 along the inner surface of the slide groove 402, thereby cooperating with the T-slot 404 to lock the position of the limit block 401 and the rectangular block 304.

[0045] The right end of the rubber pad 2 is movably connected to a baffle 5, the bottom end of the baffle 5 passes through the track 1 and extends to the inside of the track 1 and is fixedly installed with a cross plate 6, which is movably sleeved on the inner surface of the bottom right end of the track 1.

[0046] Due to the existence of the baffle plate 5 and the transverse plate 6, the rubber pad 2 will be positioned, thereby preventing the position of the rubber pad 2 from being offset.

[0047] Among them, a second spring 7 is fixedly installed at the bottom end of the cross plate 6, and the other end of the second spring 7 is fixedly connected to the bottom end of the track 1. An extension plate 8 is fixedly installed at the right end of the cross plate 6. The outer surface of the extension plate 8 is movably connected to the inner surface of the right end of the track 1. The extension plate 8 will drive the cross plate 6 to move.

[0048] When the extension plate 8 is pressed, the extension plate 8 will move downward along the inner surface of the track 1 with the cross plate 6 and compress the second spring 7. Under the restoring action of the second spring 7, the cross plate 6 will be reset.

[0049] A long slot 9 is formed inside the extension plate 8 , and a round rod 10 is fixedly sleeved inside the long slot 9 .

[0050] The long groove 9 and the round rod 10 can fix the extension plate 8 .

[0051] A fixing rod 11 located below the round rod 10 is fixedly installed at the bottom of the right end of the track 1 , and a rotating rod 12 is movably sleeved on the outer surface of the fixing rod 11 .

[0052] The inner surface of the fixed rod 11 and the inner surface of the rotating rod 12 are both smooth, ensuring that the rotating rod 12 will not get stuck when rotating along the outer surface of the fixed rod 11.

[0053] An arc groove 13 is provided at the rear side of the top end of the rotating rod 12 , and a support block 14 is movably connected to the rear side of the bottom end of the rotating rod 12 . The left end of the support block 14 is fixedly connected to the right end of the track 1 .

[0054] The width of the arc groove 13 is consistent with the diameter of the round rod 10 , and the width of the rotating rod 12 is consistent with the width of the long groove 9 , thereby ensuring that the round rod 10 can be embedded in the arc groove 13 and the rotating rod 12 can rotate along the inner surface of the long groove 9 .

[0055] The working principle and use process of this utility model:

[0056] First, when installing the rubber pad 2, the operator presses the extension plate 8, so that the extension plate 8 moves downward with the cross plate 6 and the baffle 5 along the inner surface of the bottom end of the track 1 and compresses the second spring 7, and then rotates the rotating rod 12 to rotate around the fixed rod 11 until the round rod 10 is embedded in the arc groove 13, thereby completing the fixation of the position of the baffle 5. When the rubber pad 2 is installed, the rotating rod 12 is rotated in the opposite direction to separate the round rod 10 and the arc groove 13. At this time, under the restoring action of the second spring 7, the cross plate 6 with the baffle 5 and the extension plate 8 will be restored to their original position, thereby blocking and positioning the rubber pad 2 to prevent the rubber pad 2 from shifting in position during the subsequent installation and fixation process.

[0057] Before installing the rubber pad 2, the operator needs to push the long rod 403 horizontally, so that the long rod 403 moves to the left along the inner surface of the T-slot 404 with the limit block 401 and the rectangular block 304 and compresses the first spring 305. When the long rod 403 moves to the left end inside the T-slot 404, the long rod 403 is pushed longitudinally, so that the long rod 403 moves along the inner surface of the slide groove 402 and the T-slot 404, thereby locking the position of the rectangular block 304. After the rubber pad 2 is completely installed and blocked and positioned by the baffle 5, the operator pushes the long rod 403 longitudinally. At this time, under the recovery action of the first spring 305, the rectangular block 304 will move with the limit block 401 and the rectangular block 304. The limit block 401 and the long rod 403 move laterally along the inner surface of the T-slot 404, so that the bottom end of the connecting rod 303 moves along with the rectangular block 304, and then the top end of the connecting rod 303 generates a thrust on the bottom end of the connecting plate 302, pushing the connecting plate 302 to move upward with the pointed block 301 until the pointed block 301 and the rubber pad 2 are tightly fitted. At this time, the first spring 305 is still in a compressed state, so that the pointed block 301 continues to generate an upward force on the rubber pad 2, thereby fixing the rubber pad 2 and preventing the rubber pad 2 from moving and falling off, thereby affecting the anti-vibration and noise reduction effect of the rubber pad 2.
