The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
Embodiments of the present invention will be described in detail with reference to fig. 1 to 11.
The embodiment of the invention provides a pair of chopsticks for psychiatric department, which comprises: the chopsticks comprise a shell 1, chopstick rods 2 arranged in the shell 1 and an elastic layer 3 coated on the outer surface of the shell 1. It should be understood that the elastic layer 3 may be made of soft and non-toxic rubber, silicone rubber or resin. The front end of the shell 1 is provided with an opening for the chopstick rod 2 to pass through. It will be appreciated that the front end of the resilient layer 3 also has an opening through which the chopstick bar 2 passes. Furthermore, the opening of the elastic layer 3 may be set to be slightly smaller than the diameter of the chopstick rod 2; so that the opening of the elastic layer 3 rubs the periphery of the chopstick rod 2, and the chopstick rod 2 cannot shrink inwards due to a small amount of external force; so as to reduce the internal and external floating of the chopstick rod 2 when the food is clamped, and make the chopstick rod 2 more stable when the food is clamped. An elastic member 4 for pushing the chopstick rod 2 out towards the housing 1 is arranged in the housing 1. When the front end of the chopstick rod 2 is pushed towards the inside of the shell 1 by external force and the external force is larger than the elastic force of the elastic piece 4, the chopstick rod 2 is completely contained in the shell 1. It should be appreciated that by selecting the elastic member 4 with a moderate elasticity, the maximum length of the chopstick 2 protruding from the casing 1 and the maximum external force required for the complete accommodation of the chopstick 2 into the casing 1 can be adjusted. When the front end of the chopstick rod 2 is in a natural state without external force, the chopstick rod 2 partially extends out of the opening of the shell 1 under the action of the elastic piece 4. It should be understood that, in order to avoid the chopstick 2 from completely coming out of the front end of the casing 1, an anti-coming-out structure for limiting the chopstick 2 may be further provided at the front end of the casing 1, for example: on the basis of consistent inner diameter of the shell 1, the chopstick rod 2 is gradually thickened from front to back; or on the basis of consistent thickness of the chopstick rod 2, the inner diameter of the shell 1 is gradually increased from front to back; or the chopstick rod 2, the elastic piece 4 and the shell 1 are fixedly connected, and the elastic piece 4 is prepared from a material with good toughness and difficult stretch breaking; in addition, the chopstick rod 2 can be limited by other structures, so that the chopstick rod is prevented from being completely separated from the front end of the shell 1.
The following describes embodiments of the present invention, in which an external force is applied to the front end of the chopstick 2 when a psychiatrist uses the chopstick to perform a punching operation; the more violent the punching action is, the larger the external force is; when the external force reaches a certain degree, the chopstick rod 2 can be completely contained in the shell 1; the outer surface of the shell 1 is wrapped with an elastic layer 3, so that injuries caused when a psychopath uses chopsticks to forcefully strike himself or herself or others can be avoided or reduced. When the front end of the chopstick rod 2 is not acted by external force, the front section of the chopstick rod 2 extends out of the shell 1; in the process of clamping food by using chopsticks, the front end of the chopstick rod 2 can also receive certain external force, in order to avoid the chopstick rod 2 from completely shrinking into the shell 1 during normal use, the use training of patients is dealt with, and the situation that the chopstick rod 2 completely shrinks into the shell 1 due to overlarge force when the patients clamp food is avoided. The chopsticks can reduce the risk of injury or self injury of the mental patients, meet the humanized requirements of the mental patients, and improve the living experience of the mental patients.
In one embodiment disclosed in the application, the rear end of the shell 1 is provided with a mounting opening for assembling the chopstick rod 2, and the mounting opening is provided with internal threads and is matched with a sealing piece 5 with external threads; the sealing member 5 and the shell 1 are jointly covered in the elastic layer 3. It should be understood that the chopstick rod 2 is penetrated from the rear end of the shell 1, then the sealing piece 5 is screwed on, and then the elastic layer 3 is coated on the outer surfaces of the shell 1 and the sealing piece 5 by means of 3D printing, thermoplastic, hot melting and the like; thus, the assembly of the chopsticks can be completed. By providing an installation opening at the rear end of the housing 1 and adapting the sealing member 5, the assembly of the chopsticks can be more conveniently accomplished.
In one embodiment disclosed in the application, the elastic layer 3 is provided with a first buffer part 6 at the front end of the shell 1 and a second buffer part 7 at the rear end of the shell 1; the first buffer part 6 and the second buffer part 7 are hemispherical, and the first buffer part 6 is provided with a through hole for the chopstick rod 2 to pass through; the pressure sensor is arranged on one inward side of the sealing piece 5, the button cell is arranged on one outward side of the sealing piece, and the pressure sensor is electrically connected with the button cell and the buzzer. It will be appreciated that the buzzer may be mounted either inside the closure 5 or outside the closure 5. The pressure sensor, the button cell and the buzzer are also provided with a control circuit, when a patient uses chopsticks to perform the punching, and the chopstick rod 2 is completely received in the shell 1, the pressure value detected by the pressure sensor reaches a preset threshold value, then an alarm can be sent out through the buzzer, the pressure sensing pressure alarm is the mature prior art, and the structure and the principle of the pressure sensing pressure alarm are not repeated. In addition, the second buffer part 7 is cut off by scissors, so that the button cell can be replaced; the second buffer part 7 is bonded with the shell 1, the sealing piece 5 and the elastic layer 3 again through glue, and then the second installation of the second buffer part 7 can be completed.
In one embodiment disclosed in the application, the inner wall of the shell 1 is provided with a first limit edge 8 extending backwards from the opening, and the periphery of the chopstick rod 2 is provided with a first limit groove 9 extending backwards from the front end; the first limiting edges 8 are matched with the first limiting grooves 9, and when the rear ends of the first limiting edges 8 are propped against the rear ends of the first limiting grooves 9, the chopstick rods 2 are in the maximum extending state. It should be understood that the first limiting groove 9 and the first limiting edge 8 form an anti-falling structure, so that the chopstick rod 2 can be prevented from falling out of the shell 1, and the chopstick rod 2 is prevented from being pulled out by a patient, so that the patient or other people are prevented from being injured. Compared with the limit through the front thin and rear thick chopstick rod 2 structure or the shell 1 structure, the limit device has the following advantages: 1. in the process of clamping food, the chopstick rod 2 cannot be retracted into the shell 1 by a small amount to cause a large gap between the outer periphery of the chopstick rod 2 and the inner periphery of the shell 1, so that the chopstick rod 2 is prevented from shaking left and right when clamping food. 2. When a patient pulls the chopstick rod 2 outwards, the chopstick rod 2 cannot be clamped with the shell 1, so that the chopstick rod 2 cannot be normally retracted into the shell 1 when being subjected to inward external force is avoided.
Further, the elastic piece 4 is arranged between the rear end of the chopstick rod 2 and the sealing piece 5; the elastic member 4 is a spring or a strip made of silica gel, rubber or silicone rubber.
Further, a first salient point 10 is arranged on the inner wall of the shell 1, the surface of the first salient point 10 is an arc surface or a spherical surface, and a first groove 11 matched with the first salient point 10 is arranged on the peripheral wall of the chopstick rod 2; when the chopstick rod 2 is in the maximum extension state, the first protruding point 10 corresponds to the first groove 11 in position. It should be understood that when the chopstick 2 is extended outwards under the action of the elastic member 4, the front end of the chopstick 2 is pinched or snapped by the hand and the chopstick 2 is pulled to the maximum extension state, so that the first protruding point 10 and the first groove 11 can be clamped; thus, the stability of the chopstick rod 2 when clamping food can be further improved by matching the friction of the opening of the elastic layer 3 to the periphery of the chopstick rod 2; accordingly, the elastic layer 3 may be made of a softer material. It should be noted that the first bump 10 should not be too large in size or degree of protrusion to avoid the patient from being unable to retract the chopstick 2 into the casing 1 normally when the patient uses the chopsticks to perform a punching operation.
In one embodiment disclosed in the application, the front section of the shell 1 is provided with internal threads and is adapted to a tubular limiting member 12 with external threads; the inner wall of the limiting piece 12 is provided with a second limiting edge 13, and the front section of the chopstick rod 2 is provided with a second limiting groove 14 matched with the second limiting edge 13; when the rear end of the second limiting edge 13 abuts against the rear end of the second limiting groove 14, the chopstick rod 2 is in the maximum extending state; the limiting piece 12 and the shell 1 are jointly wrapped in the elastic layer 3. It should be understood that the second limit groove 14 of the chopstick rod 2 is aligned with the second limit edge 13 of the limit piece 12, so that the chopstick rod 2 penetrates into the limit piece 12 from the rear end, then the limit piece 12 is screwed into the shell 1, and finally the elastic layer 3 is coated on the outer surfaces of the shell 1 and the limit piece 12, so that the assembly of the chopstick can be completed.
Further, the elastic member 4 is made of silica gel, rubber or silicone rubber, and the elastic member 4 is in a linear shape or a belt shape; the two ends of the elastic piece 4 are fixedly connected with the limiting piece 12; the chopstick rod 2 is provided with a clamping groove for accommodating the middle part of the elastic element 4 at the rear end, or is provided with a radial through hole for the elastic element 4 to pass through at the rear section. It should be understood that the two ends of the elastic member 4 may be fixedly connected to the tail end of the limiting member 12 by means of gluing, hot melting, etc.; radial holes penetrating the inner and outer peripheral surfaces of the limiting piece 12 can be formed in the tail portion of the limiting piece, and the elastic piece 4 and the limiting piece 12 can be connected in a knotting, winding and other modes. In addition, for patients with relatively heavy illness, the elastic piece 4 with proper length, thickness and material can be selected according to actual requirements; when the chopstick rod 2 is fully retracted into the casing 1 by the impact of a patient, the elastic member 4 breaks by extending to a limit length; so that the chopstick rod 2 can not pop out of the shell 1 any more, and the chopstick rod 2 is prevented from being blocked by repeated punching and damaging the patient or other people. In addition, a receiving groove for receiving the elastic member 4 may be provided at the middle rear section of the chopstick 2 to extend in the length direction thereof.
Further, a second protruding point 15 is arranged on the inner wall of the limiting piece 12, the surface of the second protruding point 15 is an arc surface or a spherical surface, and a second groove 16 matched with the second protruding point 15 is arranged on the peripheral wall of the chopstick rod 2; when the chopstick rod 2 is in the maximum extension state, the second protruding point 15 corresponds to the second groove 16 in position. It should be understood that the second bump 15 functions and principles are similar to those of the first bump 10, and will not be described in detail herein; in addition, when the stopper 12 is provided in the housing 1, the first bump 10 does not need to be provided on the inner wall of the housing 1.
In one embodiment disclosed in the application, the middle part of the shell 1 is provided with an anti-swallow piece 17; the anti-swallow member 17 includes: a first ring part 18 sleeved on the periphery of the shell 1, and a second ring part 19 used for preventing a patient from swallowing and allowing fingers to pass through; the first ring portion 18 and the second ring portion 19 are integrally formed, and the anti-swallow member 17 and the housing 1 are wrapped in the elastic layer 3 together. It will be appreciated that the anti-swallow member 17 prevents the psychopath from swallowing chopsticks into the abdomen.
