Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electromagnetic door suction technology, and in particular relates to a magnetic door suction positioning component that automatically returns to its original position. Background Technology
[0002] A door is an access device for a house or room, serving the basic functions of separating space and ensuring security. Electromagnetic locks (or magnetic locks) are designed like electromagnets, utilizing the principle of electromagnetism. When current passes through a silicon steel sheet, the electromagnetic lock generates a strong attraction force that tightly holds the iron plate, achieving the locking effect. Even a small current can generate a tremendous magnetic force. The access control system that controls the electromagnetic lock's power supply cuts off the power after correctly identifying the person, and the electromagnetic lock loses its attraction force, allowing the door to open. Magnetic locks are divided into two types based on the installation environment: wall-mounted and embedded. Nowadays, automatic door closing is achieved through hydraulic door closers.
[0003] The hydraulic oil in existing hydraulic door closers is easily affected by the external temperature, which can cause the door to close too slowly or too quickly, resulting in collisions and noise. The impact force of closing the door too quickly increases the probability of damaging the electromagnetic lock of the door. At the same time, there is a possibility of hydraulic oil leakage. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0036] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.
[0037] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0038] like Figures 1 to 5 As shown, an automatic door magnetic positioning component according to an embodiment of the present invention includes:
[0039] Door frame body 1, with door body 2 hinged to the door frame body 1;
[0040] The repositioning component 3 is disposed on the door frame body 1 and the door body 2, and is used to reposition the door body 2. The repositioning component 3 consists of a repositioning unit 31 and a buffer unit 32. The repositioning unit 31 includes:
[0041] The fixing box 311 is fixedly installed on the main body 2 of the door;
[0042] The first connecting rod 312 is rotatably fitted onto the door frame body 1;
[0043] The second connecting rod 313 is rotatably fitted onto the first connecting rod 312;
[0044] A drive shaft 314 is fixedly mounted on the second connecting rod 313. The drive shaft 314 is rotatably engaged with the fixed box 311. A drive gear 315 is also fixedly mounted on the drive shaft 314.
[0045] The rack plate 316 is slidably fitted in the fixed box 311, and the rack plate 316 is meshed with the drive gear 315.
[0046] The return spring 317 has its end face and free end connected to the fixed box 311 and the rack plate 316, respectively.
[0047] Push rod 318 is fixedly installed on the end face of rack plate 316, and push rod 318 is slidably engaged with fixed box 311;
[0048] Push plug 319 is fixedly installed on the end face of push rod 318, and push plug 319 slides in conjunction with fixed box 311;
[0049] Specifically, as a further embodiment of this utility model, the fixed box 311 is provided with an air inlet and an air outlet, and the buffer unit 32 includes:
[0050] An exhaust check valve 321 is fixedly installed on the exhaust port of the fixed box 311;
[0051] The gas supply pipe 322 is fixedly installed on the exhaust check valve 321, and the exhaust pipe 323 is fixedly installed on the end face of the gas supply pipe 322.
[0052] An intake check valve 324 is fixedly installed on the intake port of the fixed housing 311;
[0053] The purification box 325 is rotatably fitted onto the air intake pipe of the air intake check valve 324;
[0054] The purification filter plate 326 is snapped onto the purification box 325;
[0055] The adsorption filter plate 327 is snapped onto the purification box 325, which is located near the bottom of the purification filter plate 326.
[0056] The filter plate 328 is snapped onto the end face of the purification box 325 and is used to filter dust and impurities.
[0057] Specifically, as a further embodiment of this utility model, the purification filter plate 326 is an activated carbon filter plate used to purify and deodorize the air, and the adsorption filter plate 327 is an adsorption cotton filter plate used to adsorb water vapor in the air.
[0058] In this embodiment of the present invention, during actual application, when the door body 2 is opened, both the first connecting rod 312 and the second connecting rod 313 rotate, while the drive shaft 314 rotates synchronously with the second connecting rod 313. This causes the rack plate 316 to be subjected to a meshing force and move linearly within the fixed box 311, compressing the return spring 317 and storing energy. Simultaneously, the rack plate 316 drives the push plug 319 to move within the fixed box 311 via the push rod 318, causing the gas within the fixed box 311 to flow from the exhaust one-way valve 321 to the gas supply pipe 322 through the exhaust port. The gas is then discharged through the exhaust pipe 323, spraying air onto the surface of the filter plate 328, causing impurities adsorbed on the surface of the filter plate 328 to be impacted and dislodged. Due to the return spring 31... 7 is compressed and stored. When the door body 2 is not pushed, the stored energy of the return spring 317 is released, pushing the rack plate 316 to reset, thereby causing the drive gear 315 and drive shaft 314 to rotate, driving the second connecting rod 313 and the first connecting rod 312 to automatically return the door body 2 to its original position. When the rack plate 316 resets, it drives the push plug 319 to move through the push rod 318, which will cause the gas to enter the fixed box 311 through the purification box 325 and the air inlet one-way valve 324, controlling the speed of the door body 2 returning to its original position and avoiding the situation where the door body 2 returns to its original position too fast or too slow. The filter plate 328, the adsorption filter plate 327 and the purification filter plate 326 sequentially filter, dry and purify the inhaled gas to avoid impurities clogging it.
[0059] By setting up the return unit 31 and the buffer unit 32, the door can be automatically returned to its original position and the speed of the door's return can be controlled. Moreover, the absence of built-in hydraulic oil further reduces the interference of external temperature and avoids hydraulic oil leakage. The gas emission and intake also reduce the production cost of the components. Filtering the intake gas and reusing the emission gas increases the practicality of this application.
[0060] like Figures 1 to 5 As shown, as a further embodiment of the present utility model, the drive shaft 314 is composed of a large-diameter shaft segment and a small-diameter shaft segment. The small-diameter shaft segment is fixedly connected to the large-diameter shaft segment. The large-diameter shaft segment is connected to the second connecting rod 313. The small-diameter shaft segment is rotatably engaged with the fixed box 311. The drive gear 315 is fixedly installed on the small-diameter shaft segment. The rack plate 316 is L-shaped.
[0061] In this embodiment of the utility model, in practical application, since the large diameter shaft segment is larger than the small diameter shaft segment, dust can be avoided from adhering to the fixing box 311 and causing blockage of the small diameter shaft segment, thus making the stability of the door body 2 in place better.
[0062] like Figures 1 to 5As shown, as a further embodiment of this utility model, an electromagnetic adsorption component 4 is also installed on the door frame body 1 for magnetic positioning of the door body 2.
[0063] Specifically, as a further embodiment of this utility model, a rubber pad 11 is also installed on the outer wall surface of the door frame body 1 near the electromagnetic adsorption component 4. The rubber pad 11 is elastic. A magnetic block 21 is also fixedly installed on the door body 2 for magnetic cooperation with the electromagnetic adsorption component 4.
[0064] In this embodiment of the utility model, when the door body 2 is returned to its original position, it is first buffered by the rubber pad 11. At the same time, the magnetic force generated by the electromagnetic adsorption component 4 when it is energized is magnetically adsorbed by the magnetic block 21, so that the door body 2 and the door frame body 1 are firmly fixed.
[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
