Description
Technical Field
The invention relates to a door stopper, in particular to an adjustable buffer type door stopper.
Background
When the door is blown or opened and closed forcefully, the inertia of the door is large, and if the door cannot be decelerated in time after reaching a limiting position, impact is formed on the mechanical limiting device, so that larger noise is generated, and meanwhile, the door is deformed and glass on the door is broken due to impact.
Based on the above problems, chinese patent publication No. CN206091659U discloses an automatic damping-variable buffering and damping door stopper based on eddy current braking, which comprises an eddy current damping tube, a magnet and a supporting structure thereof, and a terminal buffering and fixing device, wherein the magnet is connected with the supporting structure, and the terminal buffering and fixing device is connected with the terminal inside of the eddy current damping tube.
The device utilizes the eddy current braking principle, which is as follows: the faraday's law of electromagnetic induction indicates that when a conductor is in a changing magnetic field or moves relative to the magnetic field, the magnetic flux passing through any loop of the conductor may change, and during the change of the magnetic flux, induced current will be generated to form eddy currents, and the magnetic field formed by the induced eddy currents tries to block the sudden change of the magnetic flux, thereby generating a damping effect to form a braking effect. The faster the relative movement speed is, the stronger the damping is, and when the speed is reduced, the damping is weakened, and the damping effect can be automatically changed according to the speed. Therefore, the prior art applies the vortex brake principle to door stopper to achieve good buffering effect and control impact, vibration, noise and the like in the door opening and closing process.
However, the eddy current damper tube of this prior art has a fixed length, and is only suitable for the buffering effect in either a low wind speed or a high wind speed, and it is not possible to realize the buffering in both a low wind speed and a high wind speed. This is because the longer the length of the eddy current damper tube, the longer the magnet passes through the eddy current damper tube, and the longer the damping maintenance time for the magnet. If the length of the eddy current damping tube is too long, the magnet is likely to be difficult to pass through the eddy current damping tube to be attracted with the tail end buffering and fixing device under the condition of low wind speed; however, when the length of the vortex damper is smaller, the damping requirement under the condition of low wind speed can be met, but the damping requirement under the condition of high wind speed can not be met, so that the door is deformed and glass on the door is broken due to impact. Because coastal areas are fully affected by typhoons in summer for a long time, the typhoon wind power reaches 12 levels or more, and high wind power is braked by using vortex damping pipes with longer lengths, the danger avoiding mechanism of the door plate under the condition of sudden high wind speed is particularly important.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-11, an adjustable buffering door stopper comprises a hinge seat 1, a sliding seat 2, a telescopic vortex damping tube assembly 3 and a pile 4, wherein the hinge seat 1 is arranged on a door plate 5, and the sliding seat 2, the telescopic vortex damping tube assembly 3 and the pile 4 are sequentially arranged on a wall. The sliding seat 2 and the telescopic vortex damping tube assembly 3 are connected with the same sliding rod 6 in a sliding way. One end of the sliding rod 6, which is close to the iron pile 4, is provided with a strong magnetic steel 7, the other end of the sliding rod is hinged with a connecting rod 8, and one end of the connecting rod 8, which is away from the sliding rod 6, is hinged with the hinge seat 1.
The telescopic vortex damping tube assembly 3 comprises a mounting seat 9 which is fixed on a wall, one side, deviating from the wall, of the mounting seat 9 is provided with a telescopic sleeve seat 10, the inner wall of the telescopic sleeve is horizontally and slidably connected with a telescopic sleeve 11, and the inner wall of the telescopic sleeve 11 is horizontally and slidably connected with a sliding sleeve 12. The side of the sliding sleeve 12 facing the mounting seat 9 is provided with a sliding block 13, and the mounting seat 9 is horizontally provided with a sliding rail 14 for sliding the sliding block 13. The slider 13 is provided with a locking mechanism 15 for locking the slider 13 and the slide rail 14 to limit the slide sleeve 12, and the locking mechanism 15 is electrically connected with a wind speed sensor 16 provided on the door panel 5. One side of the sliding sleeve 12 is provided with a spring 17 which can provide sliding power for the sliding sleeve 12, and the other end of the spring 17 is connected with the mounting seat 9. The mounting base 9 is also provided with an adjusting mechanism 18 for adjusting the sliding speed of the telescopic tube 11 by adjusting the compression degree of the spring 17.
When in actual use, the rotation of the door plate 5 can drive the displacement of the hinge seat 1 to change, and then the connecting rod 8 is driven to synchronously move, at the moment, the connecting rod 8 drives the sliding rod 6 to slide along the inner wall of the sliding seat 2 and the inner wall of the telescopic vortex damping tube assembly 3, and meanwhile, the sliding rod 6 drives the powerful magnetic steel 7 to slide on the inner wall of the telescopic vortex damping tube assembly 3, and the powerful magnetic steel 7 is gradually close to the iron pile 4.
At the same time, the strong magnetic steel 7 can cause eddy current damping effect in the telescopic eddy current damping tube assembly 3 when passing through the telescopic eddy current damping tube assembly 3. And the faster the door plate 5 is closed, the faster the sliding speed of the sliding rod 6 is, and the stronger the strong magnetic steel 7 is at the greater the eddy current magnetic resistance intensity that the flexible vortex damping tube assembly 3 produced simultaneously, therefore can effectually reduce the rotation speed of the door plate 5 to the minimum. When the strong magnetic steel 7 passes through the telescopic eddy current damping tube assembly 3, the strong magnetic steel 7 can be stably adsorbed on the iron pile 4.
Because the length of the telescopic eddy current damping tube assembly 3 is adjustable, when the wind speed sensor 16 detects that strong wind with 12 stages or more blows, an electric signal is transmitted to the locking mechanism 15 to unlock the sliding block 13 and the sliding rail 14. At this time, the spring 17, which is originally in a compressed state, provides the sliding sleeve 12 with the power required by sliding under the action of self elastic potential energy, so that the sliding sleeve 12 slides along the axial direction of the sliding sleeve, and the purpose of prolonging the eddy current damping tube is achieved. The adjusting mechanism 18 can adjust the compression degree of the spring 17 and further adjust the sliding distance and the sliding speed of the sliding sleeve 12. If the length of the telescopic vortex damping tube assembly 3 is longer, the resistance maintenance time is longer, and the deceleration effect of the door plate 5 is more obvious, so the telescopic vortex damping tube assembly can be suitable for being used under typhoon or strong wind conditions with more than 12 levels, has the risk avoiding effect, and can protect the door plate 5.
When the length of the vortex damping tube is not adjustable, the vortex damping tube is fixed. If the length is small, the requirements of use in most of time (such as no wind or low wind speed) can be met, but the requirements of sudden high wind speed can not be met. If the length is longer, the device can be suitable for the use requirement under the condition of high wind speed, but because the length is too long, the longer the resistance is maintained, the strong magnet steel 7 is likely to be difficult to pass through the telescopic eddy current damping tube assembly 3 to be attracted with the iron column under the condition of no wind or low wind speed, so that the device is particularly important to solve the problem that the door plate 5 is prevented from being damaged under the condition of high wind speed.
Further, the sliding seat 2 comprises an elongated seat plate 19, a pair of sliding tubes 20 are arranged on the seat plate 19 side by side and horizontally, and a ceramic inner core 21 abutting against the outer wall of the sliding rod 6 is arranged on the inner wall of the sliding tube 20. When the sliding rod 6 slides in the sliding seat 2, the inner wall of the ceramic inner core 21 is abutted against the outer wall of the sliding rod 6, and at the moment, the friction force between the sliding seat 2 and the sliding rod 6 is reduced by arranging the ceramic inner core 21, so that the sliding process of the sliding rod 6 is smoother, and the clamping phenomenon of the sliding rod 6 is avoided.
Further, an outer edge 22 is arranged on the outer wall of one end, close to the telescopic sleeve seat 10, of the telescopic sleeve 11 and the sliding sleeve 12, and an inner edge 23 for abutting against the outer edge 22 is arranged on one end, close to the sliding sleeve 12, of the telescopic sleeve seat 10 and the telescopic sleeve 11.
Further, the adjusting mechanism 18 includes a push plate 24 connected to one end of the spring 17, and a cam 25 capable of moving the push plate 24 toward or away from the spring 17 is disposed at one end of the push plate 24 away from the spring 17, and the cam 25 is rotatably connected to the mounting seat 9. One side of the cam 25 is also provided with a fastener 26 which limits the rotational position of the cam 25. By adjusting the rotational position of the cam 25, and thus the displacement of the push plate 24 in contact with the cam 25, the push plate 24 is moved toward or away from the spring 17, thereby adjusting the degree of compression of the spring 17. After the adjustment is completed, the position of the cam 25 is fixed by the fastener 26.
Further, the locking mechanism 15 includes a rotating shaft 27, a cavity 28 is disposed in the slider 13, and the rotating shaft 27 is horizontally rotatably connected in the cavity 28. One end of the rotating shaft 27 in the cavity 28 is provided with a locking plate 29, the outer wall of the locking plate 29 is hinged with a locking rod 30, and the locking plate 29 is provided with a yielding groove 31 which is convenient for the locking rod 30 to rotate. The upper end surface of the sliding block 13 is provided with a square hole 32 for the locking rod 30 to pass through, and the inner wall of the sliding rail 14 is provided with a locking groove 33 which can be matched with the locking rod 30. One end of the rotating shaft 27 outside the sliding block 13 is provided with a micro servo motor 34 capable of driving the rotating shaft 27 to rotate, and the micro servo motor 34 is electrically connected with the wind speed sensor 16.
In actual use, the rotation of the rotating shaft 27 drives the hinged locking rod 30 to change in position and height, so that the change in height brings about whether the locking rod 30 is exposed out of the square hole 32 to be matched with the locking groove 33 on the slide rail 14. The specific description is as follows: the cross-sectional area of the square hole 32 and the locking groove 33 described herein needs to be larger than the cross-sectional area of the locking lever 30. And the length direction of the square hole 32 and the locking groove 33 is required to be consistent with the rotation direction of the rotating shaft 27.
According to the method, when the wind speed sensor 16 detects that 12-level or more strong wind attacks the outside, an electric signal is transmitted to the micro servo motor 34, and the micro servo motor 34 controls the rotating shaft 27 to rotate by a corresponding angle, so that the locking rod 30 is hidden in the square hole 32. At this time, the sliding sleeve 12 can be driven to move under the action of the spring 17 so as to increase the length of the telescopic eddy current damping tube group, so that the telescopic eddy current damping tube group is suitable for being used under the condition of wind speed of 12 stages or more.
The present invention is not limited by the specific embodiments, and modifications can be made to the embodiments without creative contribution by those skilled in the art after reading the present specification, but are protected by patent laws within the scope of claims of the present invention.
