Description

Technical Field

[0001] The present application relates to the technical field of wooden doors, and in particular to a semi-hidden magnetic attraction component for wooden doors. Background Art

[0002] The wooden door magnetic suction component is a device widely used in various types of wooden doors. Its main function is to use magnetic force to make the door close automatically and keep the door in a closed state.

[0003] The existing wooden door magnetic suction assembly is obviously inconvenient in places where people frequently enter and exit, such as during office hours. Since the magnetic suction assembly will automatically close after the door is closed, a certain external force needs to be applied to overcome the magnetic force each time the door is opened. For people who frequently enter and exit, this will make the door opening process more laborious and reduce the traffic efficiency.

[0004] And when the door needs to be opened for ventilation, the existing magnetic components will also cause trouble. Due to its strong magnetic attraction, even if the door is only slightly opened, once it is subjected to external forces such as wind or accidental contact by a person, the door will quickly close and be sucked together under the action of the magnetic component. This makes it very difficult to use the door gap for ventilation, and it cannot meet the user's needs to keep the door gap open when ventilation is needed.

[0005] In order to solve this problem, the present application proposes a semi-hidden magnetic suction component for a wooden door. Utility Model Content

[0006] The purpose of this application is to propose a semi-hidden magnetic attraction component for wooden doors in response to the technical problems pointed out in the background technology.

[0007] The technical solution of the present application is: a semi-hidden magnetic attraction component for a wooden door, comprising a wooden door component and a door frame component, wherein an inner rotating cylinder is provided in the wooden door component; a semicircular magnet is fixed behind the inner rotating cylinder; a closing cylinder is installed in the door frame component, and an attracting magnet is installed in the closing cylinder; the attracting magnet and the opposing surfaces of the semicircular magnet are arranged with opposite magnetic poles.

[0008] Preferably, a fixing ring is embedded at the rear of the wooden door piece, and limiting rings are respectively provided on the front and rear sides of the fixing ring. The limiting ring is connected to the inner rotating cylinder, and a rotating ring is connected to the front end of the inner rotating cylinder.

[0009] Preferably, a semi-hidden cavity is provided in front of the wooden door piece, and the front end of the inner rotating cylinder and the rotating circle are both located in the semi-hidden cavity.

[0011] Preferably, a movable hole is opened in the middle of the central block, a push-pull rotary rod is arranged in the movable hole, the front end of the push-pull rotary rod extends into the front of the inner rotating cylinder, the rear end of the push-pull rotary rod is connected to a positioning round block, the front end of which is equipped with two limit blocks, and a convex block is fixed on each of the upper and lower sides of the positioning round block;

[0012] A positioning circular hole is provided in the middle of the rear of the closing cylinder, and the positioning circular hole is symmetrical with the positioning circular block. A rectangular groove is provided on each of the upper and lower sides of the positioning circular hole, and a blocking block is fixed on one side of the rear of the upper rectangular groove.

[0013] Preferably, there is a clearance opening between the two attraction magnets, and a semicircular clearance hole is respectively provided in the middle of one side where the two attraction magnets are close to each other.

[0014] Compared with the prior art, this application has the following beneficial technical effects:

Detailed implementation manners

[0023] The technical solutions of this application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0024] Generally, the components of the embodiments of this application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of this application that is required to be protected, but merely represents the selected embodiments of this application.

[0025] Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of this application.

[0026] Embodiment 1

[0027] As Figures 1-5 shown, a semi-hidden magnetic attraction assembly for a wooden door proposed in this application includes a wooden door member 1 and a door frame member 2. An inner rotating cylinder 5 is provided inside the wooden door member 1; a semi-circular magnet 7 is fixed behind the inner rotating cylinder 5. A closing cylinder 3 is installed inside the door frame member 2, and an attracting magnet 4 is installed inside the closing cylinder 3; the opposite surfaces of the attracting magnet 4 and the semi-circular magnet 7 are arranged with opposite magnetic poles. The inner rotating cylinder 5 can drive the semi-circular magnet 7 to rotate so as to adjust the magnetic poles opposite to the attracting magnet 4. After the wooden door is closed, the design of opposite magnetic poles enables the attracting magnet 4 and the semi-circular magnet 7 to be adsorbed by magnetic force, so that the wooden door is closed.

[0028] A fixing ring 8 is embedded and installed behind the wooden door member 1. Limiting rings 6 are respectively arranged on the front and rear sides of the fixing ring 8. The limiting rings 6 are connected to the inner rotating cylinder 5, and the front end of the inner rotating cylinder 5 is connected to a rotating ring 17. The rotating ring 17 can drive the inner rotating cylinder 5 to rotate inside the fixing ring 8 and drive the limiting rings 6 to rotate on the front and rear sides of the fixing ring 8, which can prevent the inner rotating cylinder 5 from shifting or falling off during the rotation process.

[0029] There is a semi-hidden cavity in front of the wooden door part 1, and the front end of the inner rotating cylinder 5 and the rotating ring 17 are both located in the semi-hidden cavity. The semi-hidden cavity can provide certain protection for the front end of the inner rotating cylinder 5 and the rotating ring 17, making these components less vulnerable to accidental collisions from the outside or other physical damages. Moreover, the semi-hidden design is more aesthetically pleasing.

[0030] There are two semi-circular magnets 7 and two attracting magnets 4 respectively. Among them, the two semi-circular magnets 7 are separated by the central block 13. The side of the semi-circular magnet 7 close to the door frame part 2 is the S magnetic pole and the N magnetic pole from top to bottom respectively, and the side of the attracting magnet 4 close to the wooden door part 1 is the N magnetic pole and the S magnetic pole from top to bottom respectively. This magnetic pole distribution facilitates the rotation function of the semi-circular magnet 7. When the semi-circular magnet 7 rotates, the upper and lower magnetic poles change simultaneously, becoming the state of like poles repelling each other, which can conveniently realize the function that the door cannot be closed, meeting the requirements of scenarios such as frequent personnel entry and exit or ventilation.

[0031] The working principle of this embodiment is: by fixing the wooden door part 1 and the door frame part 2 on the wooden door and the door frame respectively, when closing the wooden door, the semi-circular magnet 7 enters the closing cylinder 3, and at the same time, the semi-circular magnet 7 and the attracting magnet 4 attract each other with opposite magnetic poles, realizing the rapid closing of the wooden door.

[0032] During the period of frequent personnel entry and exit or when ventilation is required through the door gap, the inner rotating cylinder 5 is driven by the rotating ring 17 to rotate 180°. The inner rotating cylinder 5 drives the two semi-circular magnets 7 to rotate. At this time, the magnetic poles of the two semi-circular magnets 7 opposite to the attracting magnet 4 change, and they become the state of like poles repelling each other with the attracting magnet 4, making the wooden door unable to be closed, thus meeting the requirements of scenarios such as frequent personnel entry and exit or ventilation through the door gap.

[0033] Embodiment Two

[0034] A semi-hidden magnetic attraction assembly for a wooden door proposed by the present utility model, based on Embodiment One, as Figures 1-5 shown, there is also an activity hole in the middle of the central block 13. A push-pull rotating rod 14 is arranged in the activity hole. The front end of the push-pull rotating rod 14 extends into the front of the inner rotating cylinder 5. The rear end of the push-pull rotating rod 14 is connected with a positioning round block 15. Two limiting blocks are installed at its front end. One convex block 16 is fixed on each of the upper and lower sides of the positioning round block 15. The push-pull rotating rod 14 can move back and forth in the activity hole, thus facilitating driving the positioning round block 15 and the convex block 16 to move back and forth. There is a positioning round hole 11 in the middle of the rear of the closing cylinder 3. The positioning round hole 11 is symmetrical to the positioning round block 15. One rectangular groove 18 is opened on each of the upper and lower sides of the positioning round hole 11. A blocking block 12 is fixed on one side of the rear of the upper rectangular groove 18. After the convex block 16 rotates and is misaligned with the rectangular groove 18, the wooden door can be locked to avoid accidental opening of the wooden door due to external force.

[0035] There is a relief opening between two attracting magnets 4, and a semi-circular relief hole 10 is formed in the middle of each of the two sides of the attracting magnets 4 that are close to each other. When the attracting magnet 4 attracts the semi-circular magnet 7, the central block 13 enters the relief opening to prevent a gap from being generated between the wooden door and the door frame after the wooden door is closed.

[0036] The working principle of this embodiment is as follows: When it is necessary to lock the wooden door, the positioning round block 15 and the convex block 16 are pushed through the relief hole 10 by pushing and pulling the rotating rod 14. Then, the positioning round block 15 passes through the positioning round hole 11, and the convex block 16 passes through the rectangular groove 18. Next, the positioning round block 15 is driven to rotate counterclockwise by pushing and pulling the rotating rod 14, so that the rectangular groove 18 and the convex block 16 are misaligned with each other. At this time, the limiting block contacts the rear part inside the inner rotating cylinder 5, thereby completing the connection between the wooden door member 1 and the door frame member 2, locking the wooden door, and making the wooden door not easily opened by external force by mistake.

[0037] When it is necessary to open the wooden door, rotate the push-pull rotating rod 14 clockwise. The push-pull rotating rod 14 drives the convex block 16 to rotate through the positioning round block 15 until the convex block 16 contacts the blocking block 12. At this time, the convex block 16 is blocked by the blocking frame, and then the push-pull rotating rod 14 cannot rotate. At the same time, the convex block 16 and the rectangular groove 18 are in opposite positions, and thus the wooden door can be opened. The positioning round block 15 and the convex block 16 can be pulled out through the positioning round block 15 and the rectangular groove 18 respectively. This easy operation method can greatly improve the convenience of use.

[0038] As mentioned above, it is only the preferred specific embodiment of the present utility model. Based on the technical solution of this application and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments; the above specific embodiments are only explanations of this application, and they do not limit this application.
