Description

Technical Field

[0001] This utility model relates to the field of magnetic lock technology, specifically to a magnetic lock with protective function. Background Technology

[0002] Existing magnetic locks typically consist of a lock body, a fixed plate, and a suction plate (also known as an electromagnet block, relay plate, or auxiliary plate). The fixed plate is installed on the door frame, the lock body is mounted on the fixed plate with screws, and the suction plate is fixed to the door. The lock body and the suction plate work together to open or close the door. However, in actual use, due to prolonged use, the screws used to fix the lock body are prone to loosening, causing the lock body to fall off, resulting in damage to the magnetic lock. There is even a safety hazard of the magnetic lock falling and injuring people. Moreover, the magnetic lock cannot issue a warning signal in time after it becomes loose or falls off, so it cannot be noticed by relevant personnel in a timely manner. Its function is limited and its safety is poor.

[0003] A search revealed Chinese patent publication number CN219672371U, which discloses a magnetic lock with anti-smashing function. This patent utilizes a protective frame, shock-absorbing springs, a protective top plate, support columns, limiting slide plates, a connecting frame, and a buffer pad. The protective top plate, located at the front end of the shock-absorbing springs, overlaps the surface and back of the magnetic lock body. When the outer protective frame is impacted, multiple sets of internal shock-absorbing springs and damping shock absorbers buffer and protect the inner magnetic lock body. The limiting slide plates on both sides stabilize the inner magnetic lock body, preventing it from shifting during swaying. The connecting frame and buffer pad absorb some of the impact force, thus protecting the inner magnetic lock body. This achieves multiple buffering and protection effects on the exterior of the magnetic lock body and facilitates operation by staff.

[0004] However, when the above-mentioned device is used, although it reduces the impact force on the magnetic lock when it is impacted by the combination of protective frame and shock-absorbing spring, thus protecting the magnetic lock body, the above-mentioned device can only protect the magnetic lock body and reduce the impact of vibration. However, the door on which the magnetic lock is installed will be vibrated, causing the screws at the installation point of the magnetic lock to loosen, which will cause the magnetic lock to fall off and be damaged. Utility Model Content

[0005] This utility model proposes a magnetic lock with protective function, which has the advantages of protecting the magnetic lock body from long-term vibration and preventing it from falling off the door panel, thus improving its protective function. It solves the problem that the magnetic lock body will fall off the door panel due to vibration after long-term use, which will cause damage to the magnetic lock body.

[0006] The technical solution of this utility model is as follows: A magnetic lock with protective function includes a door panel. A strip groove is opened on the front side of the door panel. A first slot is opened in the middle of the rear side of the inner cavity of the strip groove. A second slot is opened at the bottom of the first slot. A torsion shaft is rotatably installed on the top of the inner cavity of the strip groove. A stop bar is fixedly installed at the bottom of the torsion shaft. A groove is opened on the front side of the stop bar. A first magnet is fixedly installed on the rear side of the stop bar. A second magnet is fixedly installed on the top of the rear side of the inner cavity of the strip groove. A protective frame is detachably installed in the inner cavity of the strip groove. An installation groove is opened on the right side of the protective frame. A plug is fixedly installed on the rear side of the protective frame. Spring shock absorbers are fixedly installed on the rear side and the upper and lower inner walls of the inner cavity of the installation groove. An extrusion plate is fixedly installed on the other side of the spring shock absorber. A magnetic lock body is detachably installed in the inner cavity of the installation groove. A vertical groove is opened on the front side of the inner cavity of the installation groove. A rubber pad is fixedly installed in the inner cavity of the vertical groove.

[0007] Preferably, the shape of the vertical cross-section of the first slot cavity matches the shape of the vertical cross-section of the insertion rod, and the height of the first slot cavity is greater than the height of the insertion rod, so that the height and shape of the first slot cavity facilitate the insertion of the rod during use.

[0008] Preferably, the shape of the horizontal cross-section of the second slot cavity matches the shape of the horizontal cross-section of the insertion rod. The horizontal cross-section of the insertion rod is T-shaped, so that when in use, the shape of the horizontal cross-section of the second slot cavity and the shape of the horizontal cross-section of the insertion rod make it easy for the insertion rod to be inserted into the second slot cavity from the first slot, and after insertion, the insertion rod prevents it from automatically moving out of the second slot cavity.

[0009] Preferably, the bottom of the insertion rod is on the same horizontal plane as the bottom of the protective frame, and the distance between the top of the insertion rod and the top of the protective frame is less than the distance between the top of the first slot cavity and the bottom of the horizontal stop bar. Thus, when in use, after the stop bar is rotated clockwise to the horizontal, it is convenient for the protective frame and the insertion rod to extend into the inner cavity of the strip groove and for the insertion rod to extend into the inner cavity of the first slot.

[0010] Preferably, the position of the first magnet on the rear side of the stop bar matches the position of the second magnet on the rear side of the inner cavity of the strip groove. The magnetic poles of the first magnet and the second magnet are opposite on opposite sides. Therefore, when in use, by utilizing the installation positions of the first magnet and the second magnet and the opposite magnetic poles on opposite sides, when the stop bar rotates into the inner cavity of the strip groove, the first magnet and the second magnet prevent the stop bar from being unable to move out of the inner cavity of the strip groove when there is no external force.

[0011] Preferably, after the stop bar is rotated vertically into the inner cavity of the strip groove, the height between its top and the bottom of the installed protective frame matches the height of the inner cavity of the strip groove. A rubber layer is fixedly installed on the outer surface of the stop bar. Thus, during use, the height of the stop bar and the protective frame, plus the rubber layer on the outer surface of the stop bar, increases the friction between the stop bar and the inner wall of the strip groove, preventing the stop bar from moving out of the inner cavity of the strip groove when there is no external force.

[0012] Preferably, the extrusion plate is connected to the rear side and upper and lower sides of the mounting groove cavity through a spring damper. The right side of the extrusion plate has an arc-shaped design, so that when in use, the arc-shaped design of the right side of the extrusion plate facilitates the quick insertion of the magnetic lock body into the mounting groove cavity. The extrusion plate and the spring damper work together to fix the magnetic lock body in the mounting groove cavity.

[0013] Preferably, the shape of the cross-section of the vertical groove is smaller than the shape of the front surface of the magnetic lock body. The front surface of the protective frame after being installed into the groove and the front surface of the stop bar rotated into the groove are both on the same vertical horizontal plane as the front surface of the door panel. Thus, when in use, the rubber pad prevents the magnetic lock body from quickly coming into direct contact with the door frame, thereby reducing the damage to the magnetic lock body and improving the protective function of the magnetic lock body.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] This protective magnetic lock works by combining a spring damper structure and a protective plate structure. When in use, the magnetic lock body is inserted between the mounting groove and the gap in the extrusion plate. The spring damper and the protective frame prevent the vibration force from the door panel from being directly transmitted to the magnetic lock body. The rubber pad prevents the magnetic lock body from directly contacting the door frame, thus protecting the magnetic lock body from prolonged vibration that could cause it to fall off the door panel and improving its protective function.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1-4As shown, a magnetic lock with protective function includes a door panel 1. A strip groove 2 is formed on the front side of the door panel 1. A first slot 3 is formed in the middle of the rear side of the inner cavity of the strip groove 2. The shape of the vertical cross-section of the inner cavity of the first slot 3 matches the shape of the vertical cross-section of the insertion rod 12. The height of the inner cavity of the first slot 3 is greater than the height of the insertion rod 12, thus facilitating the insertion of the insertion rod 12 during use. A second slot 4 is formed at the bottom of the first slot 3. The shape of the horizontal cross-section of the inner cavity of the second slot 4 matches the shape of the horizontal cross-section of the insertion rod 12. The horizontal cross-section of the insertion rod 12 is T-shaped, thus facilitating the insertion of the insertion rod 12 from the first slot 3. The first magnet is inserted into the inner cavity of the second slot 4 at slot 3, and after insertion, the insert rod 12 prevents it from automatically moving out of the inner cavity of the second slot 4. A torsion shaft 5 is rotatably mounted on the top of the inner cavity of the strip groove 2, and a stop rod 6 is fixedly mounted on the bottom of the torsion shaft 5. A groove 7 is opened on the front side of the stop rod 6, and a first magnet 8 is fixedly mounted on the rear side of the stop rod 6. A second magnet 9 is fixedly mounted on the top of the rear side of the inner cavity of the strip groove 2. The position of the first magnet 8 on the rear side of the stop rod 6 matches the position of the second magnet 9 on the rear side of the inner cavity of the strip groove 2. The magnetic poles of the first magnet 8 and the second magnet 9 are opposite on opposite sides. Therefore, in use, by utilizing the installation position of the first magnet 8 and the second magnet 9 and their opposite magnetic poles, when the stop rod 6 rotates into the inner cavity of the strip groove 2, the first magnet 8 and the second magnet 9... 9. To prevent the stop bar 6 from being unable to move out of the inner cavity of the strip groove 2 when no external force is applied, a protective frame 10 is detachably installed in the inner cavity of the strip groove 2. After the stop bar 6 is rotated vertically and positioned in the inner cavity of the strip groove 2, the height between the top of the stop bar 6 and the bottom of the installed protective frame 10 matches the height of the inner cavity of the strip groove 2. A rubber layer is fixedly installed on the outer surface of the stop bar 6. Thus, during use, the height of the stop bar 6 and the protective frame 10, plus the rubber layer on the outer surface of the stop bar 6, increases the friction between the stop bar 6 and the inner wall of the strip groove 2, preventing the stop bar 6 from moving out of the inner cavity of the strip groove 2 when no external force is applied. An installation groove 11 is opened on the right side of the protective frame 10, and an insert rod 12 is fixedly installed on the rear side of the protective frame 10. The bottom of the insert rod 12 is at the same level as the bottom of the protective frame 10, and the top of the insert rod 12... The distance between the top of the part and the top of the protective frame 10 is less than the distance between the top of the inner cavity of the first slot 3 and the bottom of the horizontally rotated stop bar 6. Therefore, when in use, after the stop bar 6 is rotated clockwise to the horizontal position, it is convenient for the protective frame 10 and the insertion rod 12 to extend into the inner cavity of the strip groove 2 and for the insertion rod 12 to extend into the inner cavity of the first slot 3. Spring damping dampers 13 are fixedly installed on the rear side and the upper and lower inner walls of the inner cavity of the mounting groove 11. A pressing plate 14 is fixedly installed on the other side of the spring damping damper 13. The pressing plate 14 is connected to the rear side and the upper and lower inner walls of the inner cavity of the mounting groove 11 through the spring damping damper 13. The right side of the pressing plate 14 has an arc design. Therefore, when in use, the arc design on the right side of the pressing plate 14 facilitates the quick insertion of the magnetic lock body 15 into the inner cavity of the mounting groove 11.The magnetic lock body 15 is fixed in the inner cavity of the mounting groove 11 by the compression plate 14 and the spring damper 13. The magnetic lock body 15 is detachably installed in the inner cavity of the mounting groove 11. A vertical groove 16 is opened on the front side of the inner cavity of the mounting groove 11. A rubber pad 17 is fixedly installed in the inner cavity of the vertical groove 16. The cross-sectional shape of the inner cavity of the vertical groove 16 is smaller than the shape of the front surface of the magnetic lock body 15. The front surface of the protective frame 10 after being installed into the inner cavity of the strip groove 2 and the front surface of the stop bar 6 after being rotated into the inner cavity of the strip groove 2 are both on the same vertical horizontal plane as the front surface of the door panel 1. Therefore, when in use, the rubber pad 17 prevents the magnetic lock body 15 from quickly coming into direct contact with the door frame, thereby reducing the damage to the magnetic lock body 15 and improving the protective function of the magnetic lock body 15.

[0024] Working principle: During operation, the magnetic lock body 15 is first inserted into the mounting groove 11 in the middle of the protective frame 10 from right to left. The arc-shaped design on the right side of the extrusion plate 14 facilitates the quick insertion and fixation of the magnetic lock body 15 between the upper and lower sides and the rear extrusion plates 14. The spring damper 13 reduces the vibration force transmitted from the door panel 1 to the protective frame 10 and then from the protective frame 10 to the magnetic lock body 15. Next, the operator inserts their finger into the groove 7 and rotates the stop bar 6 forward. Then, the assembled protective frame 10 and its internal structure are pushed out of the inner cavity of the strip groove 2. The insertion of the rod 12, which is fixedly installed on the rear side of the protective frame 10, is made to extend into the inner cavity of the first slot 3 and then slide down from the inner cavity of the first slot 3 to the inner cavity of the second slot 4 until the protective frame 10 is installed into the bottom of the inner cavity of the strip groove 2. Finally, the stop rod 6 is released, so that it automatically rotates in the opposite direction and extends into the inner cavity of the strip groove 2 under the action of the torsion spring in the inner cavity of the torsion shaft 5. By utilizing the length of the stop rod 6 and the protective frame 10, in conjunction with the first magnet 8 and the second magnet 9, the stop rod 6 is prevented from automatically moving out of the inner cavity of the strip groove 2 without the action of external force, thereby improving the stability of the protective frame 10 during installation.

[0025] During use, the opening and closing of the door panel 1 over a long period of time causes the door panel 1 to vibrate. The spring damper 13 reduces the vibration force transmitted to the magnetic lock body 15. Together with the protective frame 10 and the rubber pad 17, this protects the magnetic lock body 15 and improves its protective function during use.

[0026] In summary, compared with similar devices, this magnetic lock with protective function has the advantage of protecting the magnetic lock body from prolonged vibration that could cause it to fall off the door panel 1, thus improving its protective function.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
