[0001] The utility model relates to the technical field of restraint belts, and particularly relates to a self-locking magnetic buckle restraint belt. Background Art

[0002] Inpatients with abnormal mental behaviors may cause dangerous behaviors such as difficulty in cooperating with treatment, running away, self-harm and suicide, and hurting people and damaging objects due to the decline of recognition and control ability. To ensure the safety of patients, surrounding people and the smooth progress of treatment, protective compulsory restraint is given.

[0003] Traditional cloth restraint belts: The material is cotton cloth. According to the restraint method and using a protective pad, the patient's wrists, shoulders, back and ankles are fixed, and tightened to a width that can fit in or two transverse fingers and tied with a dead knot to the bed. Although it can be fixed, it is relatively cumbersome to open.

[0004] Although there are currently restraint belts with magnetic buckles, which are fixed by the cooperation of magnetic needles and magnetic caps, although this bundling and fixing method is convenient to open, due to the lack of a corresponding locking mechanism, once the external force is too large or the patient struggles violently, the separation between the magnetic needle and the magnetic cap may occur, resulting in the failure of the restraint belt.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] As Figures 1-3 shown, a self - locking magnetic buckle restraint band includes a main band 1 and a sub - band 2. A plurality of guide holes 3 are opened at the ends of the main band 1 and the sub - band 2, and metal guide rods 4 that are matched and installed with the guide holes 3 are opened at the tails of the main band 1 and the sub - band 2;

[0026] A circle of limit slots 5 is opened on the axial surface of the metal guide rod 4, and an elastic locking cap 6 is inserted on the metal guide rod 4. The diameter of the elastic locking cap 6 is larger than the diameter of the guide hole 3;

[0027] The elastic locking cap 6 can be locked in the limit slot 5 under its own elastic force, so that the main band 1 can be locked to form a restraint band sleeved on the patient's limb.

[0028] Among them, the elastic locking cap 6 and the metal guide rod 4 can be automatically locked. After the metal guide rod 4 is inserted into the elastic locking cap 6, even if the patient resists violently or is subjected to external force by others, it is impossible to separate the elastic locking cap 6 from the metal guide rod 4. If you want to separate the elastic locking cap 6 from the metal guide rod 4, you now need to use a magnet 17. The connection between the elastic locking cap 6 and the metal guide rod 4 is unlocked by the magnetism of the magnet 17, and after unlocking, the main band 1 can be taken out from the patient's limb.

[0029] This device can realize the locking between the elastic locking cap and the metal guide rod through a self - locking structure composed of a metal slider, a spring and a metal ball, so as to realize the locking between the main band and the patient's limb. After locking, the main band will not loosen even when the patient resists violently, and can only be unlocked by using a magnet, avoiding the possibility of the patient unlocking it by himself or others unlocking it casually.

[0030] Specifically, as Figures 2-3As shown, the bottom of the elastic locking cap 6 is provided with a socket 7 matched with the metal guide rod 4, the inner cavity of the elastic locking cap 6 is provided with a limiting groove 9 connected with the socket 7, the inner cavity of the limiting groove 9 is slidably connected with a metal slider 8, and the inner cavity of the metal slider 8 is provided with a through hole 10 for the metal guide rod 4 to slide through;

[0031] A spring 11 that can be sleeved on the metal guide rod 4 is connected between one end surface of the metal slider 8 and the top of the limiting groove 9;

[0032] A metal ball 12 that can be snap-fitted into the limiting slot 5 is movably installed in the limiting slot 9 on the side away from the spring 11 .

[0033] Further, such as Figures 2-3 As shown, one end of the limiting groove 9 close to the socket is configured as an arc-shaped structure 13 , and the arc-shaped structure 13 and the limiting slot 5 are at the same height.

[0034] In this way, when the metal ball completely falls into the bottom of the limiting groove 9, it can automatically roll into the limiting slot 5 under the transition effect of the arc-shaped structure 13, and the spring 11 can squeeze the metal slider 8 downward under its own elastic force, and squeeze the metal ball 12 into the limiting slot 5 through the metal slider 8. Since the activity space of the metal ball 12 is limited, the metal guide rod 4 and the elastic locking cap 6 are locked.

[0035] When unlocking is required, it is only necessary to use the magnet, wherein the magnet can attract the metal slider 8 and the metal ball 12 at the same time. The metal slider 8 and the metal ball 12 are moved upward synchronously by the magnetic attraction, thereby squeezing the spring 11. Once the metal slider 8 moves upward, the space available for the metal ball 12 to move in the limiting groove 9 increases, that is, the metal ball 12 can move upward and disengage from the limiting slot 5. At this time, the metal guide rod 4 can slide freely along the elastic locking cap 6, that is, the metal guide rod 4 and the elastic locking cap 6 can be separated;

[0036] After the metal guide rod 4 and the elastic locking cap 6 can be separated, that is, after the restraint belt is taken off the patient's limb, the elastic locking cap 6 can be inserted into the metal guide rod 4 again to be locked, so as to avoid the loss of the elastic locking cap 6.

[0037] Since the metal slider 8 can slide along the metal guide rod 4, when the metal guide rod 4 is inserted into the elastic locking cap 6, the through hole 10 of the metal guide rod 4 needs to be kept in the same vertical plane, that is, the metal slider 8 needs to be able to maintain a vertical movement posture.

[0038] Specifically, Figures 2-3 As shown, a positioning groove 14 is provided on the top of the elastic locking cap 6, and the positioning groove 14 is connected to the limiting groove 9;

[0039] A positioning rod 15 that mates with the positioning groove 14 is fixedly connected to the metal slider 8 located outside the spring 11.

[0040] Among them, in the state where the metal ball 12 is locked, the positioning rod 15 can still be inserted into the positioning groove 14.

[0041] Since it is not easy for medical staff to find the position of the restraint belt when it is used at night, the restraint needs to be made to emit light.

[0042] Specifically, as Figure 1 shown, fluorescent strips 16 are provided on the surfaces of both the main belt 1 and the auxiliary belt 2.

[0043] Observation at night is achieved through the light-emitting characteristics of the fluorescent strips 16.

[0044] When using this restraint belt, the main belt 1 is wound around the patient's limb, and the auxiliary belt 2 is tied to the hospital bed. After the main belt 1 is wound around once, the metal guide rod 4 is inserted into the guide hole 3. The choice of the guide hole 3 mainly depends on the thickness of the patient's limb. After insertion, the elastic locking cap 6 is inserted onto the metal guide rod 4. Since the elastic locking cap 6 cannot pass through the guide hole 3, the wound main belt 1 will be locked. When unlocking is required, the elastic locking cap 6 can be pulled out from the metal guide rod 4 with the aid of a magnet.

[0045] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
