[0001] The utility model relates to the technical field of lock buckles, in particular to a novel magnetically controlled lock. Background Art

[0002] Patients are prone to anesthetic reactions such as restlessness and uncontrolled activities during and after anesthesia, and need to be protectively restrained. Otherwise, not only will the surgical effect of the patient be affected, but the patient's recovery will also be seriously affected. When treating patients with mental symptoms, patients need to be protectively restrained with the help of restraint belts to prevent accidental injuries such as self-mutilation, self-injury, falling out of bed, and bedside abrasions, while ensuring the smooth progress of treatment.

[0003] In order to realize that the lock tongue does not need to be unlocked by a magnet into the lock plate, there are currently two structures in the industry. One is a structure in which a positioning column or a lock buckle cooperates with a positioning hole on the lock tongue, such as the Chinese patent publication numbers CN110495686B, CN210539265U, and CN111119604A, and the publication number CN111119604A and the patent name are an improved mini magnetic control lock, including a lock plate, a lock seat, a lock core assembly and a lock tongue, wherein the lock plate is arranged above the lock seat, the lock core assembly is arranged in the lock plate, and a socket for inserting the lock tongue is provided between the lock plate and the lock seat. A lock hole is provided on the tongue, a lock hole 1 is provided in the lock plate, a lock hole 2 corresponding to the lock hole 1 up and down is provided on the lock seat, the lock core assembly comprises an unlocking plate, a lock catch, a spring and an axle pin 1, an axle hole 1 is provided at both ends of the lock plate, both ends of the axle pin 1 are correspondingly inserted into the axle hole 1, the unlocking plate, the lock catch and the spring rotate along the axial direction of the axle pin 1, one end of the spring is pressed above the lock catch, and the other end thereof is pressed below the upper panel in the lock plate, the unlocking plate and the lock catch rotate simultaneously, and when the unlocking plate and the lock catch rotate to the lowest position, the lower end of the lock catch rotates correspondingly into the lock hole 1 and the lock hole 2.

[0004] Another is to form a rotating locking method by using an elastic component and a gear component in combination, which can effectively solve the situation of forced unlocking by using an external device in the absence of a magnetic key, thereby increasing safety performance. For example, the Chinese patent publication number CN114403556B, the patent name is a magnetically controlled lock, including a lock plate and a lock tongue used in combination, the lock plate includes a shell, and an elastic component and a rotatable gear component are respectively installed in the shell, one side of the gear component can be engaged with the elastic component, and the other side of the gear component extends to the locking part provided on the shell, and the lock tongue can be inserted into the locking part, so that the gear component is inserted into the positioning hole on the lock tongue. Compared with the traditional magnetically controlled lock, it is more convenient and simple to use, and there is no need to use a magnet to unlock and insert it, saving operation steps and time. In addition, the use of the elastic component and the gear component in combination to form a rotating locking method can effectively solve the situation of forced unlocking by using an external device in the absence of a magnetic key, thereby increasing safety performance.

[0005] In order to overcome the limitations of the two existing magnetic lock structures and meet the higher requirements of safety, convenience and reliability of medical restraint belts in protective restraints, the applicant has developed an innovative magnetic lock structure.

[0031] See also Figure 1-9 As shown, the utility model relates to a new type of magnetic lock, including a magnetic key (not shown), a lock tongue 1 and a lock body, and the lock tongue 1 is provided with a plurality of positioning holes 11. The lock tongue 1 can be directly inserted into the lock body from the insertion channel 21 on one side of the lock body and pushed forward to a suitable position for locking, and it is not necessary to use a magnetic key to unlock it before inserting it. It is convenient to use, simple to operate, and saves operation steps and time. When the lock tongue 1 is inserted into the lock body, the lock plate 3 is pushed by the lock tongue 1 and rotates in the lock seat 2, that is, the lock plate 3 can rotate in the insertion direction. After the lock tongue 1 is inserted into the insertion channel 21 of the lock body to a certain position, the lock plate 1 is locked in the lock body after the lock catch portion 35 on the lock plate 3 is inserted into the positioning hole 11 on the lock tongue 1. The lock plate 3 cannot rotate in the lock seat 2 when the lock tongue 1 is pulled out. The magnetic key is essentially a magnet. When the lock plate 3 is adsorbed by the magnetic key, it rotates in the lock body and causes the lock catch portion 35 to be separated from the positioning hole 11 on the lock tongue 1, and the lock tongue 1 can be pulled out of the lock body.

[0032] The existing magnetic locks all have the problem of being easily unlocked accidentally by external force impact and having poor anti-theft performance. They also include a safety lock assembly, which is another lock on the lock body. The lock body cannot be unlocked even when it is hit by external force or adsorbed by a magnetic key. The safety lock assembly includes a sliding shaft, and the sliding shaft 5 has a locking position and an unlocking position. When the sliding shaft 5 is in the unlocking position, the rotation restriction on the lock plate 3 is released, and the magnetic key adsorbs the lock plate 3 to achieve the unlocking purpose. When the sliding shaft 5 is in the locking position, under the action of the sliding shaft 5, the sliding shaft 5 limits the rotation of the lock plate 3 to achieve the locking function.

[0033] After the locking portion 35 on the locking plate 3 is inserted into the positioning hole 11 of the locking tongue 1, the locking tongue 1 is pulled out of the lock body (when the locking tongue 1 moves backward), driving the locking plate 3 to rotate downward and get stuck in the positioning hole 11, and the locking portion 35 cannot be separated from the positioning hole 11, and the locking tongue 1 can only be pushed forward but cannot move backward directly, so that the locking tongue 1 can be locked in time to prevent the locking tongue 1 from falling off. When the locking tongue 1 needs to be unlocked, it is only necessary to use the magnetic control key to adsorb on one side of the lock body to attract the locking plate 3 to rotate upward through the magnetic force, and the locking portion 35 can be separated from the positioning hole 11 and the locking tongue can be pulled out.

[0034] The lock body includes a housing 7, a lock seat 2, a lock plate 3, and a positioning magnet 4. The positioning magnet 4 and the lock plate 3 are arranged inside the lock seat 2, and the housing 7 wraps the lock seat 2. The lock plate 3 is rotatably connected to one side of the lock seat 2 through an axle pin 31. The two ends of the axle pin 31 are respectively fixed to the left and right sides of the lock seat 2. The lock plate 3 is provided with a lifting ear 32. The axle pin 31 passes through the lifting ear 32 to fix the lock plate 3 in the lock seat 2. The lock plate 3 includes an integrally formed unlocking plate 33, a limiting plate 34, and a locking portion 35. The locking portion 35 is a tongue structure and is arranged to be bent downward. The locking portion 35 is located below the unlocking plate 33. The limiting plate 34 is arranged between the unlocking plate 33 and the locking portion 35. The limiting plate 34 is located below the unlocking plate 33 and is arranged parallel to the limiting plate 34. The unlocking plate 33 and the limiting plate 34 form a clamping opening 36 for clamping the sliding shaft 5.

[0035] The unlocking piece 33 , the limiting piece 34 and the locking part 35 rotate axially along the shaft pin 31 at the same time. When the locking piece 3 rotates to the bottom, the locking part 35 rotates accordingly and is inserted into the positioning hole 11 , and the positioning magnet 4 attracts the locking part 35 in the positioning hole 11 .

[0036] In this embodiment, the locking portion 35 is inserted into the positioning hole 11 , and the locking portion 35 is adsorbed and fixed by the positioning magnet 4 , so that the locking portion 35 is fixedly installed in the positioning hole 11 .

[0037] The lock base 2 is provided with sliding holes 23 on both sides, and the sliding shaft 5 is inserted into the lock base 2 through the sliding holes 23. The sliding shaft 5 is arranged between the unlocking piece 33 and the limiting piece 34. At the same time, the sliding shaft 5 limits the limiting piece 34 along the sliding holes 23, so that the limiting piece 34 cannot continue to rotate, thereby further locking the lock part 35 on the positioning hole 11.

[0038] Furthermore, in this embodiment, the lock base 2 is mounted on the bottom plate in cooperation with the bottom cover 6, wherein the bottom of the lock base 2 is provided with an insertion channel 21 for the lock tongue 1 to slide, and the top of the bottom cover 6 is provided with an arc surface 61, the bottom cover 6 is located at the bottom of the lock base 2, and the arc surface 61 is located in the insertion channel 21. In this embodiment, the lock tongue 1 is inserted into the bottom of the lock base 2, the lock tongue 1 passes through the insertion channel 21 and is located above the arc surface 61, the lock tongue 1 is supported by the arc surface 61, and the positioning hole 11 is opened due to the support of the arc, thereby facilitating the docking installation of the lock buckle portion 35 and the positioning hole 11.

[0039] Furthermore, in this embodiment, a magnet placement groove 22 is provided inside the lock base 2 , and the magnet placement groove 22 passes through both sides of the lock base 2 . The magnet placement groove 22 is arranged above the top of the arc surface 61 , and the positioning magnet 4 is installed in the magnet placement groove 22 .

[0040] Furthermore, in this embodiment, the lock base 2 is provided with first shaft holes 24 on both sides, the shaft pin 31 is installed on the first shaft hole 24, and the lifting ear 32 is respectively connected to the unlocking piece 33, the limiting piece 34 and the locking part 35. When the lifting ear 32 rotates, the lifting ear 32 drives the locking part 35 to insert or withdraw from the positioning hole 11. When the locking part 35 is inserted into the positioning hole 11, the positioning magnet 4 provides a certain adsorption force to the locking part 35, and the locking part 35 is adsorbed on the positioning magnet 4 to prevent the locking part 35 from shaking.

[0041] Furthermore, in this embodiment, the sliding hole 23 is disposed in a “U” shape on both sides of the lock seat 2 , and the sliding hole 23 has a locking position 231 and an unlocking position 232 , and the unlocking position 232 is located above the locking position 231 .

[0042] The sliding shaft 5 is located at the unlocking position 232. When the lock tongue 1 is inserted into the insertion channel 21, the locking piece 3 can be pushed by the lock tongue 1 and rotated in the lock seat 2. After the lock tongue 1 stops being pushed into the lock body, the lock tongue 1 stops at a certain position of the insertion channel 21. The locking portion 35 of the locking piece 3 is inserted into the positioning hole 11. The positioning magnet 4 adsorbs the locking portion 35 in the positioning hole 11. The positioning magnet 4 achieves the reset of the locking piece 3 and adsorbs the locking piece 3 to prevent the locking piece 3 from shaking. For safety, the user can move the sliding shaft 5 along the sliding hole 23 to the locking position 231, and rotate the limiting plate 34 of the sliding shaft 5 to further lock the lock tongue 1 with the locking piece 3. When unlocking, by moving the sliding shaft 5 to the unlocking position 232, the restriction of the limiting plate 34 is cancelled at this time, and the user can adsorb and rotate the locking piece 3 through the magnetic control key to disengage the locking portion 35 from the positioning hole 11.

[0043] In order to enhance the limiting effect of the sliding shaft 5 on the limiting piece 34 and improve the stability of the locking part 35 when locked. In this embodiment, a support rod 51 and an elastic member 52 are further provided in the lock seat 2, and second shaft holes 25 are provided on both sides of the lock seat 2. The support rod 51 is connected and installed in the second shaft hole 25. One end of the elastic member 52 is connected to the support rod 51, and the other end is traction-connected to the sliding shaft 5. The elastic member 52 pulls the sliding shaft 5, so that the sliding shaft 5 is subjected to traction when it is located at the unlocking position 232, thereby enhancing the limiting effect on the limiting piece 34, and also effectively preventing the problem of automatic unlocking caused by accidental touch.

[0044] In order to allow the user to better operate the sliding shaft 5 , grips 53 are provided at both ends of the sliding shaft 5 , and the user can better control the sliding shaft 5 through the grips 53 .

[0045] The utility model relates to a new type of magnetically controlled lock, in which the locking piece 3 locks the lock tongue 1 by inserting the lock catch part 35 into the positioning hole 11. The utility model adopts the positioning magnet 4 to provide adsorption force to the lock catch part 35 to prevent the lock catch part 35 from shaking. At the same time, in the utility model, "U"-shaped sliding holes 23 are arranged on both sides of the lock seat 2. When the lifting ear 32 drives the lock catch part 35 to rotate into the positioning hole 11, the sliding shaft 5 can be moved to the locking position 231 of the sliding hole 23, and the sliding shaft 5 rotates and limits the limit plate 34, so that the limit plate 34 cannot rotate, thereby improving the stability of the lock catch part 35 when locked. Move the sliding shaft 5 to the unlocking position 232 of the sliding hole 23, contact the sliding shaft 5 to limit the rotation of the limit plate 34, and the magnetically controlled key can magnetically adsorb the unlocking piece 33. The unlocking piece 33 is reset to drive the lock catch part 35 to leave the positioning hole, thereby completing the unlocking. In addition, in the present invention, the "U"-shaped design of the sliding hole 23 and the design of pulling the sliding shaft 5 by the elastic member 52 can effectively prevent the problem of automatic unlocking caused by accidental touch.
