Description

Technical Field

[0001] The utility model relates to the field of anti-breakage devices for accidental contact of thermometers, and specifically to an anti-breakage device for accidental contact in the production of thermometers. Background Technique

[0002] A thermometer is a maximum thermometer. The working substance of the thermometer is mercury. Its glass bulb has a much larger volume than the volume of the thin tube above. The mercury in the bulb undergoes a slight change due to the influence of body temperature. The expansion of the mercury volume causes a significant change in the length of the mercury column in the tube. During the production and processing of thermometers, an anti-breakage device for accidental contact is required to protect the thermometers.

[0003] A Chinese patent with the publication number CN112945407B discloses a fall-proof thermometer protection device for pediatrics, which relates to the field of medical device tools, specifically a fall-proof thermometer protection device for pediatrics. It includes: mercury head, scale glass body, rubber ring sleeve, spring support plate, L-shaped spring support frame, spring one, movable hinge shaft one, support plate one, movable hinge shaft two, support plate two, spring two, movable hinge shaft three, support plate three. Its characteristics are: the rubber ring sleeve is sleeved on the scale glass body near the mercury head, and an L-shaped spring support frame is arranged above the rubber ring sleeve at the position of the spring support plate; a movable hinge shaft one is arranged at the upper horizontal surface of the rubber ring sleeve at the position of the L-shaped spring support frame, and the movable hinge shaft one is connected with a support plate one; a movable hinge shaft two is arranged on the right side in the middle of the support plate one, and the movable hinge shaft two is connected with a support plate two; a movable hinge shaft three is arranged on the left side in the middle of the support plate one, and the movable hinge shaft three is connected with a support plate three. The structure of the present invention is simple and easy to operate, and can effectively prevent the thermometer from being broken.

[0004] The existing anti-breakage devices for accidental contact have a single structure. By adding a layer of elastic material outside the thermometer to reduce the impact force when the thermometer is hit, the thermometer will still be hit, resulting in a poor anti-breakage effect. Therefore, an anti-breakage device for accidental contact in the production of thermometers is proposed for the above problems. Content of the Utility Model

A first ball joint 5 is installed on the inner wall of the outer housing 1. A first connecting rod 6 is installed on the first ball joint 5. A damping rod 7 is installed on the first connecting rod 6. A chute 8 is formed inside the damping rod 7. A piston block 9 is assembled in the chute 8. The outer wall of the piston block 9 is in contact with the inner wall of the chute 8. A movable rod 10 is installed on the piston block 9. A second connecting rod 11 is installed on the movable rod 10. A second ball joint 12 is installed on the second connecting rod 11, and the second ball joint 12 is fixedly connected to the outer wall of the inner housing 3. The spring 4 is sleeved around the damping rod 7. The outer housing cover 2 is installed with an inner housing cover 13 through the shock-absorbing component. A first rubber block 14 is installed on the bottom side of the inner wall of the outer housing 1. A second rubber block 15 is installed on the top side of the inner wall of the outer housing cover 2. A first magnet 16 is installed on the top side of the inner housing 3. A second magnet 17 is installed on the bottom side of the inner housing cover 13. The inner housing 3 and the inner housing cover 13 are buckled through the first magnet 16 and the second magnet 17. The first magnet 16 and the second magnet 17 are in a square-ring structure. A first limiting frame 18 is installed on the bottom side of the inner wall of the inner housing 3. A second limiting frame 19 is installed on the top side of the inner wall of the inner housing cover 13. The first limiting frame 18 and the second limiting frame 19 are made of plastic. A thermometer 20 is installed inside the first limiting frame 18 and the second limiting frame 19; during operation, the existing anti-collision and anti-shattering device has a single structure. By adding a layer of elastic material outside the thermometer 20 to reduce the impact force when the thermometer 20 is hit, but the thermometer 20 will still be hit, resulting in a poor anti-shattering effect. By placing the thermometer 20 on the first limiting frame 18 of the inner housing 3, the structure of the first limiting frame 18 is adapted to that of the thermometer 20, and the thermometer 20 is firmly stuck in the first limiting frame 18. Then, the outer housing cover 2 is covered on the outer housing 1. The first magnet 16 on the inner housing cover 13 and the second magnet 17 on the inner housing 3 attract each other, realizing the accurate buckling of the inner housing cover 13 and the inner housing 3. At this time, the top side of the thermometer 20 is firmly stuck on the second limiting frame 19 of the inner housing cover 13. At this time, the thermometer 20 is firmly placed inside the inner housing cover 13 and the inner housing 3;

[0020] During the process that the outer shell 1 is accidentally touched and dropped and suffers an impact, the impact force suffered by the outer shell 1 drives the spring 4 inside it to vibrate. The spring 4 drives the inner shell cover 13 and the inner shell 3 to vibrate. The spring 4 undergoes elastic deformation and stores energy. At the same time, the spring 4 drives the inner shell cover 13 to vibrate. The inner shell cover 13 drives the second ball joint 12 to move. The second ball joint 12 drives the second connecting rod 11 to move. The second connecting rod 11 drives the movable rod 10 to move. The movable rod 10 drives the piston block 9 to move in the chute 8. A frictional resistance is generated between the outer wall of the piston block 9 and the inside of the chute 8. The frictional resistance can consume the kinetic energy of the spring 4 and also reduce the impact force. When the spring 4 returns to its original state, the frictional resistance will prevent the spring 4 from rebounding and consume the energy stored in the spring 4, making the spring 4 return to a static state; the spring 4 can absorb the impact force during vibration, playing a buffering and protective role, reducing the damage caused by the external impact to the inner shell cover 13 and the inner shell 3. The spring 4 first absorbs a part of the impact energy. At the same time, the inner shell cover 13 and the inner shell 3 themselves will also play a certain protective role, realizing double protection for the thermometer 20, avoiding the thermometer 20 from being impacted, and being beneficial to improving the anti-shattering effect.

[0021] Working principle: The existing anti-shattering device for accidental collision has a single structure. By adding a layer of elastic material outside the thermometer 20, the impact force when the thermometer 20 is hit is reduced. However, the thermometer 20 will still be hit, resulting in a poor anti-shattering effect. By placing the thermometer 20 on the first limiting frame 18 of the inner housing 3, the structure of the first limiting frame 18 is adapted to that of the thermometer 20, and the thermometer 20 is firmly stuck in the first limiting frame 18. Then, the outer shell cover 2 is covered on the outer housing 1, and the first magnet 16 on the inner shell cover 13 attracts the second magnet 17 on the inner housing 3, realizing the accurate buckling of the inner shell cover 13 and the inner housing 3. At this time, the top side of the thermometer 20 is firmly stuck on the second limiting frame 19 of the inner shell cover 13, and the thermometer 20 is firmly placed inside the inner shell cover 13 and the inner housing 3. When the outer housing 1 is accidentally hit and dropped, the impact force received by the outer housing 1 drives the spring 4 inside it to vibrate. The spring 4 drives the inner shell cover 13 and the inner housing 3 to vibrate. The spring 4 undergoes elastic deformation and stores energy. At the same time, the spring 4 drives the inner shell cover 13 to vibrate. The inner shell cover 13 drives the second ball joint 12 to move. The second ball joint 12 drives the second connecting rod 11 to move. The second connecting rod 11 drives the movable rod 10 to move. The movable rod 10 drives the piston block 9 to move in the sliding groove 8. Frictional resistance is generated between the outer wall of the piston block 9 and the inside of the sliding groove 8. The frictional resistance can consume the kinetic energy of the spring 4 and also reduce the impact force. When the spring 4 returns to its original state, the frictional resistance will prevent the spring 4 from rebounding and consume the energy stored in the spring 4, making the spring 4 return to a static state. The spring 4 can absorb the impact force during vibration, playing a buffering and protective role, reducing the damage caused by external impact to the inner shell cover 13 and the inner housing 3. The spring 4 first absorbs a part of the impact energy, and at the same time, the inner shell cover 13 and the inner housing 3 themselves also play a certain protective role, realizing double protection for the thermometer 20, avoiding the thermometer 20 from being hit, and being beneficial to improving the anti-shattering effect.
