Description

Technical Field

[0001] This utility model relates to the field of safety education and training equipment technology, and in particular to a mechanical injury simulation experience device based on safety education. Background Technology

[0002] Currently, safety education and training in the machining industry mainly relies on theoretical explanations, picture displays, or video playback. Due to the limitations of two-dimensional presentation, trainees find it difficult to intuitively perceive the potential harm risks during machine operation and lack sufficient awareness of the danger levels of typical mechanical injury scenarios such as gear meshing. This results in weak safety awareness and a high risk of accidents caused by violations of operating procedures in actual operation. Furthermore, the few existing simulation experience devices are often complex in structure and cumbersome in operation, resulting in a poor immersive and interactive experience of injury risks. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a mechanical injury simulation experience device based on safety education.

[0004] This utility model is achieved using the following technical solution: a mechanical injury simulation experience device based on safety education, comprising an experience wall, a gear simulation component capable of simulating mechanical injury using gears on one side of the experience wall, limiting components restricting the rotation angle of the gear simulation component on both sides of the gear simulation component, a fixing component capable of stopping the rotation of the gear simulation component on the top of the gear simulation component, the gear simulation component comprising two rotating columns rotatably mounted on one side of the experience wall, each of the two rotating columns being fixedly fitted with a compression gear, the two compression gears meshing with each other, and an insertion slot being opened at one end of each of the two rotating columns, with a crank handle inserted into the interior of one of the insertion slots.

[0005] Through the above technical solution, trainees can drive the gear simulation component to operate by cranking the handle, and intuitively observe the meshing process of the two extrusion gears, simulating the dangerous scenario of gear transmission in machining; at the same time, the limiting component can prevent the gear from rotating excessively, and the fixing component can quickly stop the gear from operating in an emergency, ensuring the safety of the experience.

[0006] As a further improvement to the above solution, both of the aforementioned insertion slots are arranged in a cuboid shape.

[0007] Through the above technical solution, the cuboid insertion slot can form a stable insertion fit with the end of the crank handle, avoiding circumferential slippage of the crank handle during rotation, ensuring that the force applied by the trainee can be stably transmitted to the rotating column, guaranteeing the stability and continuity of the gear simulation component's operation, and improving the reliability of the experience.

[0008] As a further improvement to the above solution, the limiting component includes a limiting post installed on one side of the experience wall and having a torsion spring inside. A locking block is fixedly installed on the cylindrical surface of the limiting post, and the locking block is set in the shape of an arc plate with one end contracting.

[0009] Through the above technical solution, the torsion spring inside the limiting post can provide elastic restoring force, so that the locking block always tends to contact the gear simulation component; the locking block structure with an arc plate and one end contracted can not only slide smoothly through the arc surface when the gear rotates, but also effectively limit the rotation angle of the gear through the contracted end, so as to avoid the gear from rotating excessively due to inertia.

[0010] As a further improvement to the above solution, a limiting groove is provided on one side of each of the two extrusion gears, and the contraction ends of the two locking blocks extend into the limiting groove of the adjacent extrusion gear.

[0011] Through the above technical solution, the retractable end of the card block is embedded in the limiting groove of the extrusion gear to form a mechanical limiting fit: when the extrusion gear rotates, the side wall of the limiting groove will contact the retractable end of the card block. Under the elastic force of the torsion spring, the card block can limit the rotation range of the extrusion gear, so that the gear can only operate within the set angle range, preventing the gear rotation angle from being too large and causing the simulated scenario to deviate from the actual mechanical injury risk scenario, thus ensuring the accuracy of the training.

[0012] As a further improvement to the above solution, the fixing component includes a protective box fixedly installed on one side of the experience wall. A push cylinder is fixedly installed on the top of the inner cavity of the protective box. A push plate is fixedly installed on the output end of the push cylinder. Rubber plates are symmetrically fixedly installed on the bottom side of the push plate. Both rubber plates are arc-shaped. A control button for controlling the push cylinder is installed on one side of the protective box.

[0013] Through the above technical solution, the protective box can protect the core components such as the push cylinder and push plate, and prevent dust and impurities from affecting the operation of the components; the control button can realize convenient control of the push cylinder. When it is necessary to stop the gear operation, the push cylinder can be started by pressing the control button; the push cylinder drives the push plate to move down, causing the arc-shaped rubber plate to fit against the surface of the extrusion gear, and the high friction characteristics of the rubber are used to quickly brake the extrusion gear.

[0014] As a further improvement to the above solution, the protective box has an experience hole and a hand crank hole on one side.

[0015] Through the above technical solution, the experience hole allows trainees to put their hands between the squeezing gears inside the protective box; the hand crank hole allows trainees to operate the crank with their other hand, allowing them to turn the crank within a safe area and slowly let the squeezing gears squeeze their hands, thereby experiencing mechanical injury.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention uses a gear simulation component to simulate a mechanical transmission scenario with two meshing compression gears. It is combined with a crank handle to achieve interactive operation, allowing trainees to control the compression force of the compression gears to squeeze their hands. This allows trainees to intuitively experience the dangers of gear operation and improve their safety awareness. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Please combine Figures 1-3 This embodiment of a mechanical injury simulation experience device based on safety education includes an experience wall 1. One side of the experience wall 1 is provided with a gear simulation component that can simulate mechanical injury using gears. Both sides of the gear simulation component are provided with limiting components that limit the rotation angle of the gear simulation component. The top of the gear simulation component is provided with a fixing component that can stop the gear simulation component from rotating.

[0025] The gear simulation component includes two rotating columns 201 rotatably mounted on one side of the experience wall 1. Each rotating column 201 is fixedly fitted with a pressing gear 202, which meshes with each other. One end of each rotating column 201 is provided with an insertion slot 203, and a crank 204 is inserted into the inside of one of the insertion slots 203. Both insertion slots 203 are rectangular.

[0026] Trainees can drive the gear simulation component through the crank 204 to intuitively observe the meshing process of the two extrusion gears 202, simulating the dangerous scenario of gear transmission in machining; at the same time, the limiting component can prevent the gear from rotating excessively, and the fixing component can quickly stop the gear from rotating in an emergency, ensuring the safety of the experience.

[0027] The limiting components include a limiting post 301 installed on one side of the experience wall 1 and having a torsion spring inside. A locking block 302 is fixedly installed on the cylindrical surface of the limiting post 301. The locking block 302 is set in the shape of an arc plate that narrows at one end.

[0028] The torsion spring inside the limiting post 301 provides elastic restoring force, so that the locking block 302 always tends to contact the gear simulation component; the locking block 302 structure with an arc plate and one end retracted can not only slide smoothly through the arc surface when the gear rotates, but also effectively limit the rotation angle of the gear through the retracted end, so as to avoid the gear from rotating excessively due to inertia.

[0029] Each of the two extrusion gears 202 has a limiting groove 5 on one side, and the contraction ends of the two locking blocks 302 extend into the limiting groove 5 of the adjacent extrusion gear 202.

[0030] The retractable end of the locking block 302 is embedded in the limiting groove 5 of the extrusion gear 202 to form a mechanical limiting fit: when the extrusion gear 202 rotates, the side wall of the limiting groove 5 will contact the retractable end of the locking block 302. Under the elastic force of the torsion spring, the locking block 302 can limit the rotation amplitude of the extrusion gear 202, so that the gear can only operate within the set angle range, preventing the gear rotation angle from being too large and causing the simulated scene to deviate from the actual mechanical injury risk scene, thus ensuring the accuracy of the training.

[0031] The fixing components include a protective box 401 fixedly installed on one side of the experience wall 1. A push cylinder 402 is fixedly installed on the top of the inner cavity of the protective box 401. A push plate 403 is fixedly installed on the output end of the push cylinder 402. Rubber plates 404 are symmetrically fixedly installed on the bottom side of the push plate 403. Both rubber plates 404 are arc-shaped. A control button 405 for controlling the push cylinder 402 is installed on one side of the protective box 401.

[0032] The protective box 401 can protect core components such as the push cylinder 402 and the push plate 403, preventing dust and impurities from affecting the operation of the components; the control button 405 can realize convenient control of the push cylinder 402. When it is necessary to stop the gear operation, press the control button 405 to start the push cylinder 402; the push cylinder 402 drives the push plate 403 to move down, causing the arc-shaped rubber plate 404 to come into contact with the surface of the extrusion gear 202. Utilizing the high friction characteristics of rubber, the extrusion gear 202 is quickly braked.

[0033] The protective box 401 has an experience hole 6 and a hand crank hole 7 on one side.

[0034] The experience hole 6 allows trainees to put their hands between the squeezing gears 202 inside the protective box 401; the hand crank hole 7 allows trainees to operate the crank handle 204 with their other hand, allowing trainees to turn the crank handle 204 within a safe area and slowly let the squeezing gears 202 squeeze their hands, thereby experiencing mechanical injury.

[0035] The implementation principle of a mechanical injury simulation experience device based on safety education in this application embodiment is as follows: The trainee first inserts the end of the crank handle 204 into the cuboid insertion slot 203 of one of the rotating columns 201. At this time, the crank handle 204 and the rotating column 201 form a stable connection to avoid slippage. Then the trainee puts his left hand into the experience hole 6 and places it between the two extrusion gears 202. Then the trainee's right hand passes through the hand crank hole 7 of the protective box 401, grasps the crank handle 204 and rotates it.

[0036] The crank handle 204 rotates, causing the rotating column 201 connected to it to rotate synchronously. The pressing gear 202 fixedly sleeved on the rotating column 201 rotates accordingly. Since the two pressing gears 202 mesh with each other, the first pressing gear 202 will drive the second pressing gear 202 to rotate in the opposite direction, which in turn drives the rotating column 201 corresponding to the second pressing gear 202 to rotate synchronously in the opposite direction, realizing the simulation of gear meshing transmission. When the pressing gear 202 rotates, it will squeeze the student's right hand. Since the crank handle 204 is controlled by the student's own right hand, the squeezing force is within the range that the student can bear.

[0037] During the rotation of the extrusion gear 202, the torsion spring always applies an elastic force to the limiting post 301, causing the locking block 302 on the cylindrical surface of the limiting post 301 to maintain contact with the extrusion gear 202. Since the retracted end of the locking block 302 extends into the limiting groove 5 of the extrusion gear 202, when the extrusion gear 202 rotates to the set angle, the side wall of the limiting groove 5 will be in close contact with the retracted end of the locking block 302. Under the elastic force of the torsion spring, the locking block 302 blocks the extrusion gear 202, restricting the extrusion gear 202 from continuing to rotate, thus preventing the trainee from using too much force and injuring their left hand.

[0038] To stop the gears from rotating, the trainee presses the control button 405 on one side of the protective box 401. The control button 405 sends a start signal to the push cylinder 402. After receiving the signal, the push cylinder 402 at the top of the inner cavity of the protective box 401 extends downward, causing the push plate 403 fixed at the output end to move down synchronously. The arc-shaped rubber plate 404 symmetrically installed on the bottom side of the push plate 403 moves down until it is in close contact with the outer cylindrical surface of the two extrusion gears 202. Utilizing the high friction of the rubber material, the rubber plate 404 generates braking resistance on the extrusion gears 202, causing the extrusion gears 202 to stop rotating quickly. This, in turn, causes the rotating column 201 and the crank handle 204 to stop moving, completing the emergency braking and ensuring the safety of the experience.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
