Description

Technical Field

[0001] The invention relates to the technical field of fluorescent imaging devices, and in particular to a fluorescent imaging device with a protective structure. Background Art

[0002] The theoretical basis for the operation of the fluorescence imaging device is that the intensity of the fluorescence signal emitted by the fluorescent substance after being excited is linearly related to the amount of fluorescent pigment within a certain range. The internal parts of the fluorescence imaging device require very high precision and high processing difficulty, so extra care must be taken when transporting the fluorescence imaging device.

[0003] Existing fluorescent imaging devices are basically protected by wrapping in foam during transportation, but this setting is often only used for the first transportation after leaving the factory. There are often no protective measures for the fluorescent imaging device during secondary transportation after unpacking or short-distance movement, or when it is accidentally touched and dropped, which can easily cause damage to the internal parts of the fluorescent imaging device. Summary of the invention

[0007] Optionally, hollow rubber balls are distributed inside the first sponge and the second sponge, and through holes are opened on the surface of the hollow rubber balls, and dry particles are arranged inside the hollow rubber balls.

[0008] Optionally, the hollow rubber ball is elastic and can automatically restore to a spherical shape after being squeezed, and the through holes are evenly distributed on the surface of the hollow rubber ball.

[0009] Optionally, the weight-sensing outer ring and the non-sensing disc are distributed in concentric circles, and the weight-sensing outer ring and the non-sensing disc are in the same plane.

[0010] Optionally, a snap-fit ​​structure is formed between the snap hook and the snap plate, and a movable structure is formed between the snap plate and the bracket via a torsion spring, and the snap plate and the bracket form an elastic structure via a tight spring.

[0011] Optionally, the protective airbag expands after being inflated and forms an adsorption connection with the surface of the fluorescent imaging device body through the magnet sheet and the magnet bar, and the protective airbag becomes a scroll shape after being deflated and rolled up.

[0012] Optionally, two protective airbags are provided, and the magnet bars are evenly distributed at the ends of the protective airbags, and the protective airbags are adsorbed to each other through the magnet bars.

[0013] Optionally, the limiting assembly includes a main arc plate, a slide groove, a friction pad, a movable rod and a secondary arc plate, the main arc plate is provided with a slide groove inside, and friction pads are provided on both sides of the inner wall of the slide groove, the slide groove is provided with a movable rod, and the outer end of the movable rod is fixed with a secondary arc plate.

[0014] Optionally, the secondary arc plate forms a telescopic structure with the main arc plate through a movable rod, a slide groove, and both sides of the movable rod are in contact with the friction pad.

[0015] The present invention provides a fluorescent imaging device with a protective structure, which has the following beneficial effects:

[0016] Before the fluorescent imaging device accidentally falls, it will inevitably tilt. Based on this, when the fluorescent imaging device tilts, the protective airbag is deployed in advance to protect the side of the fluorescent imaging device so as to reduce the impact force on the fluorescent imaging device. At the same time, the elastic effect of the spring at the bottom of the fluorescent imaging device also reduces the impact force on its bottom, thereby reducing the possibility of damage to the internal parts of the fluorescent imaging device.

[0017] 1. The fluorescent imaging device with a protective structure, when the bottom of the fluorescent imaging device body is hit, the first spring is forced to expand and contract, and at the same time, the bottom of the fluorescent imaging device body contacts the first sponge to absorb the impact force generated by the collision, thereby preventing the fluorescent imaging device body from being subjected to excessive collision force, and the hollow rubber ball cooperates with the first sponge to enhance the impact absorption effect, and at the same time cooperates with the first spring to restore the first sponge after the impact, thereby preventing the first sponge from collapsing, and the dry particles can absorb moisture, which is conducive to maintaining the dryness of the first sponge and preventing the first sponge from getting damp.

[0018] 2. In the fluorescent imaging device with a protective structure, the ball on the disk rolls on the surface of the weight-sensing outer ring and the non-sensing disc along with the inclination of the fluorescent imaging device body. When the ball on the disk rolls to the surface of the weight-sensing outer ring, the weight-sensing outer ring controls the electric detonator to start detonating the solid nitrogen particles. At this time, the solid nitrogen particles are rapidly vaporized to expand the protective airbag, and the expansion direction is controlled by the magnet sheet and the magnet bar, so that the protective airbag is closely attached to the surface of the fluorescent imaging device body and the tail connection is completed. The expanded protective airbag is conducive to reducing the impact force on the side of the fluorescent imaging device body, thereby avoiding damage to the internal parts of the fluorescent imaging device body.

[0019] 3. The fluorescent imaging device with a protective structure has an electric detonator and a threaded connection with the vent. When the electric detonator is in operation, the connection with the vent can prevent gas leakage. The electric detonator can be taken out by twisting it, so that the inside of the vent is exposed, thereby facilitating the discharge of gas inside the protective airbag, and conveniently rolling up the protective airbag to reduce the volume, and also conveniently replacing new solid nitrogen particles to prepare for the next protection of the fluorescent imaging device body.

[0020] 4. In the fluorescent imaging device with a protective structure, after the protective airbag is rolled up in a scroll shape, the main arc plate and the secondary arc plate are located on both sides of the protective airbag, which is conducive to limiting the protective airbag and preventing the protective airbag from expanding on its own. The distance between the secondary arc plate and the main arc plate can be adjusted by a movable rod, which is conducive to adapting to the diameter size of the protective airbag after rolling up. At the same time, the secondary arc plate can be extended and retracted inside the main arc plate through the movable rod, which is conducive to shrinking into the main arc plate under force when a collision occurs, avoiding the influence of hard contact on the main body of the fluorescent imaging device.

[0021] 5. In the fluorescent imaging device with a protective structure, the ventilator is connected to the snap plate by a snap hook, and the tightness of the snap connection is increased by a tight spring to prevent the protective airbag carried by the ventilator from falling off. The snap plate can be rotated by a torsion spring, and the snap plate can be flipped by lifting the ventilator with force, thereby preventing the protective airbag carried by the ventilator from falling off and avoiding the need to clean the protective airbag later.

[0030] See also Figures 1 to 7 The present invention provides a technical solution: a fluorescent imaging device with a protective structure, comprising a fluorescent imaging device body 1, a protective component 16 and a limiting component 17, a first spring 2 is arranged at the bottom of the fluorescent imaging device body 1, and the bottom of the first spring 2 is connected to a base 3, a first sponge 4 is arranged outside the first spring 2, a second spring 5 is arranged at the top of the fluorescent imaging device body 1, and the top of the second spring 5 is connected to a top shell 6, a second sponge 7 is arranged outside the second spring 5, a weight sensing outer ring 8 is embedded in the surface of the top shell 6, and a non-sensing disc 9 is arranged inside the weight sensing outer ring 8, and a running ball 10 is placed on the surface of the non-sensing disc 9, a clamping groove 11 is opened in the middle of both sides of the fluorescent imaging device body 1, and a tight spring 12 is fixed inside the clamping groove 11, a bracket 13 is fixed to the other end of the tight spring 12, and the side of the bracket 13 is connected to a buckle plate 15 through a torsion spring 14, a protective component 16 is also arranged inside the clamping groove 11, and the protective component 16 includes The snap hook 1601, the ventilator 1602, the protective airbag 1603, the filter 1604, the solid nitrogen particles 1605, the electric detonator 1606, the magnet sheet 1607 and the magnet strip 1608, the ventilator 1602 is fixed to the top outside of the snap hook 1601, and the protective airbag 1603 is wrapped outside the ventilator 1602, the filter 1604 is fixed to the bottom of the inner wall of the ventilator 1602, and the solid nitrogen particles 1605 are placed on the upper surface of the filter 1604, and the ventilator 1602 is fixed to the bottom of the inner wall of the ventilator 1602. The top of the inner wall of 602 is connected with an electric detonator 1606, a magnet sheet 1607 is arranged in the middle of the inner wall of the protective airbag 1603, and magnet strips 1608 are arranged on both sides of the inner wall of the protective airbag 1603, the limit assembly 17 is arranged on both sides of the snap-fit ​​groove 11, the snap hook 1601 and the snap plate 15 form a snap-fit ​​structure, and the snap plate 15 and the bracket 13 form a movable structure through the torsion spring 14, and the snap plate 15 and the bracket 13 form an elastic structure through the tight spring 12;

[0031] The specific operation is as follows: when the fluorescent imaging device body 1 accidentally falls and is hit, the base 3 replaces it for hard contact, and at the same time, the first spring 2 is forced to expand and contract to reduce the impact force, and during the expansion and contraction process of the first spring 2, the bottom of the fluorescent imaging device body 1 contacts the first sponge 4 to avoid the fluorescent imaging device body 1 and the base 3 from having a hard contact, thereby facilitating the maintenance of the integrity of the fluorescent imaging device body 1. Similarly, when the top of the fluorescent imaging device body 1 is hit, the second spring 5, the second sponge 7 and the top shell 6 are set to reduce the impact force, and when the fluorescent imaging device body 1 falls, it is inevitable that The ball 10 rolls over the non-sensing disc 9 and reaches the surface of the weight-sensing outer ring 8. The weight-sensing outer ring 8 controls the electric detonator 1606 to detonate the solid nitrogen particles 1605 to rapidly vaporize them. The gas passes through the filter 1604 and enters the protective airbag 1603 to rapidly expand it. During the expansion of the protective airbag 1603, the magnet sheet 1607 carries the protective airbag 1603 to the two sides of the fluorescent imaging device body 1, and the magnet bar 1608 connects the two protective airbags 1603 end to end. At the same time, the magnet bar 1608 carries the protective airbag 1603 to the fluorescent imaging device body 1. The front and rear sides of the optical imaging device body 1 are protected from the side of the fluorescent imaging device body 1. After the above steps are completed, the protective airbag 1603 replaces the fluorescent imaging device body 1 for hard contact, which is conducive to completing the protective measures in advance and reducing the possibility of damage to the fluorescent imaging device body 1. After falling, the fluorescent imaging device body 1 is straightened, and the electric detonator 1606 is twisted to take it out, so that the inside of the ventilator 1602 is exposed. At this time, the protective airbag 1603 is squeezed to discharge the gas so that it can be rolled up and wait for the next use. At the same time, it is also convenient to add new solid nitrogen particles 160 5 is prepared for the next protection, and the ventilator 1602 is fixed by inserting the snap hook 1601 into the snap groove 11 and snapping it with the snap plate 15, and the tightness of the snap hook 1601 and the snap plate 15 is increased by the tight spring 12 to prevent the ventilator 1602 from carrying the protective airbag 1603 and falling off, and the snap plate 15 can be rotated by the torsion spring 14, and the snap plate 15 can be turned over by lifting the ventilator 1602 with force, thereby preventing the ventilator 1602 from carrying the protective airbag 1603 and avoiding the need to clean the protective airbag 1603 later.

[0032] like Figure 1-2 As shown, the fluorescent imaging device body 1 forms an elastic structure through the first spring 2 and the base 3, and the first spring 2 passes through the first sponge 4 without contacting the first sponge 4;

[0033] The first spring 2 and the first sponge 4 do not contact each other, which can prevent the first spring 2 from squeezing the first sponge 4 when it contracts. Similarly, the second spring 5 and the second sponge 7 are designed in the same way, so that the second sponge 7 and the first sponge 4 can be in good contact with the top and bottom of the fluorescent imaging device body 1 to unload the force.

[0034] like Figure 1-2 As shown, hollow rubber balls 18 are distributed inside the first sponge 4 and the second sponge 7, and through holes 19 are opened on the surface of the hollow rubber balls 18. Dry particles 20 are arranged inside the hollow rubber balls 18. The hollow rubber balls 18 are elastic and can automatically restore to a spherical shape after being squeezed, and the through holes 19 are evenly distributed on the surface of the hollow rubber balls 18;

[0035] The specific operation is as follows: when the base 3 is subjected to force, the first sponge 4 cooperates with the hollow rubber ball 18 to contact the fluorescent imaging device body 1 to avoid hard contact between the fluorescent imaging device body 1 and the base 3. Then, the first sponge 4 will be propped up through the recovery function of the hollow rubber ball 18 to avoid collapse of the first sponge 4. In addition, the drying particles 20 can absorb moisture, which is beneficial to maintaining the dryness of the first sponge 4 and preventing the first sponge 4 from getting damp. The same is true for the second sponge 7.

[0036] like Figure 6 As shown, the weight sensing outer ring 8 and the non-sensing disc 9 are distributed in concentric circles, and the weight sensing outer ring 8 and the non-sensing disc 9 are in the same plane;

[0037] The weight-sensing outer ring 8 and the non-sensing disc 9 are in the same plane to facilitate the rolling of the running ball 10. When the weight-sensing outer ring 8 senses the weight of the running ball 10, it indicates that the fluorescent imaging device body 1 is tilted and there is a possibility of falling or falling, so as to avoid timely protection of the fluorescent imaging device body 1. When the running ball 10 rolls to the center surface of the non-sensing disc 9, it indicates that the fluorescent imaging device body 1 is placed horizontally. This arrangement allows people to place the fluorescent imaging device body 1 stably.

[0038] like Figure 6-7 As shown, the protective airbag 1603 expands after being inflated and forms an adsorption connection with the surface of the fluorescent imaging device body 1 through the magnet sheet 1607 and the magnet strip 1608, and the protective airbag 1603 is in a scroll shape after being deflated and rolled up;

[0039] When there is no gas inside the protective airbag 1603, it is flat, like a cardboard shape and has a flexible structure. By manually rolling it up from both ends, it can be stored in a scroll shape on both sides of the fluorescent imaging device body 1, so as to reduce the volume of the protective airbag 1603. After the protective airbag 1603 is inflated, the expansion direction of the protective airbag 1603 can be controlled with the cooperation of the magnet sheet 1607 and the magnet bar 1608, which is conducive to allowing the protective airbag 1603 to surround the fluorescent imaging device body 1 to protect it.

[0040] like Figure 1 , Figure 6-7As shown, there are two protective airbags 1603, and the magnet bars 1608 are evenly distributed at the ends of the protective airbags 1603, and the protective airbags 1603 are adsorbed by the magnet bars 1608;

[0041] Based on the magnetic adsorption effect of the magnet strip 1608, after the protective airbag 1603 is fully inflated, the ends of the two protective airbags 1603 are attracted to each other and fit together through the magnet strip 1608, thereby bending. The magnet strip 1608 at the ends of the bent protective airbag 1603 will be close to the surface of the fluorescent imaging device body 1, so that the protective airbag 1603 forms a "mouth" shape to surround and protect the fluorescent imaging device body 1.

[0042] like Figure 1 , Figure 3-4 As shown, the limiting assembly 17 includes a main arc plate 1701, a slide groove 1702, a friction pad 1703, a movable rod 1704 and a secondary arc plate 1705. The main arc plate 1701 is provided with a slide groove 1702, and friction pads 1703 are arranged on both sides of the inner wall of the slide groove 1702. A movable rod 1704 is arranged inside the slide groove 1702, and the secondary arc plate 1705 is fixed to the outer end of the movable rod 1704. The secondary arc plate 1705 forms a telescopic structure through the movable rod 1704, the slide groove 1702 and the main arc plate 1701, and both sides of the movable rod 1704 are in contact with the friction pad 1703.

[0043] After the protective airbag 1603 is rolled up in a scroll shape, the main arc plate 1701 and the secondary arc plate 1705 are located on both sides of the protective airbag 1603, which is conducive to limiting the protective airbag 1603 and preventing the protective airbag 1603 from unfolding by itself, and the distance between the secondary arc plate 1705 and the main arc plate 1701 can be adjusted by the movable rod 1704, which is conducive to adapting to the diameter size of the protective airbag 1603 after rolling up. At the same time, the secondary arc plate 1705 is retracted and expanded inside the main arc plate 1701 through the movable rod 1704, which is conducive to shrinking into the main arc plate 1701 under force when a collision occurs, so as to avoid the hard contact from affecting the fluorescent imaging device body 1.

[0044] In summary, when the fluorescent imaging device with a protective structure is used, first, when the fluorescent imaging device body 1 accidentally falls and is hit, the base 3 replaces it to make hard contact, and at the same time, the first spring 2 is forced to expand and contract to reduce the impact force, and during the expansion and contraction process of the first spring 2, the bottom of the fluorescent imaging device body 1 contacts the first sponge 4 to avoid the fluorescent imaging device body 1 and the base 3 from making hard contact, which is beneficial to maintaining the integrity of the fluorescent imaging device body 1. Similarly, when the top of the fluorescent imaging device body 1 is hit, the second spring 5, the second sponge 7 and the top shell 6 are set to reduce the impact force, and when the base 3 is stressed, the first sponge 4 cooperates with the hollow rubber ball 18 to contact the fluorescent imaging device body 1 to avoid the fluorescent imaging device body 1 and the base 3 from making hard contact, and then the first sponge 4 is propped up by the recovery function of the hollow rubber ball 18 to avoid the collapse of the first sponge 4, and the drying particles 20 can absorb moisture, which is beneficial to maintaining the dryness of the first sponge 4 and avoiding the first sponge 4 from getting damp, and the same is true for the second sponge 7;

[0045] Then, when the fluorescent imaging device body 1 falls, it will inevitably tilt. Based on this, the running ball 10 rolls over the non-sensing disc 9 to reach the surface of the weight sensing outer ring 8. The weight sensing outer ring 8 controls the electric detonator 1606 to operate and detonate the solid nitrogen particles 1605 to make it quickly gasify. The gas passes through the filter 1604 and enters the protective airbag 1603 to make it expand rapidly. During the expansion of the protective airbag 1603, the magnet sheet 1607 carries the protective airbag 1603 to the two sides of the fluorescent imaging device body 1, and the magnet bar 1608 makes the two protective airbags 1603 connected end to end. At the same time, the magnet bar 1608 carries the protective airbag 1603 to the front and back sides of the fluorescent imaging device body 1, so that the side protection of the fluorescent imaging device body 1 is completed. After the above steps are completed, the protective airbag 1603 replaces the fluorescent imaging device body 1 to make hard contact, which is conducive to completing protective measures in advance and reducing the possibility of damage to the fluorescent imaging device body 1.

[0046] Next, after falling, the fluorescent imaging device body 1 is straightened, and the electric detonator 1606 is twisted to be taken out, so that the inside of the ventilator 1602 can be exposed. At this time, the protective airbag 1603 can be squeezed to discharge the gas so that it can be rolled up and wait for the next use. It is also convenient to add new solid nitrogen particles 1605 to prepare for the next protection. After the protective airbag 1603 is rolled up in a scroll shape, the main arc plate 1701 and the secondary arc plate 1705 are located on both sides of the protective airbag 1603, which is conducive to limiting the protective airbag 1603 and preventing the protective airbag 1603 from unfolding by itself. The distance between the secondary arc plate 1705 and the main arc plate 1701 can be adjusted by the movable rod 1704, which is conducive to adapting to the diameter size of the protective airbag 1603 after rolling up;

[0047] Finally, the vent tube 1602 is fixed by inserting the snap hook 1601 into the snap groove 11 and snapping it with the snap plate 15, and the tightness of the snap hook 1601 and the snap plate 15 is increased by the tight spring 12 to prevent the vent tube 1602 from carrying the protective airbag 1603 and falling off. The snap plate 15 can be rotated by the torsion spring 14, and the snap plate 15 can be flipped by lifting the vent tube 1602 with force, thereby preventing the vent tube 1602 from carrying the protective airbag 1603 and avoiding the need to clean the protective airbag 1603 later.
