Description

Technical Field

[0001] The present invention relates to the field of infrared thermal imagers, in particular to a narrow-slit adaptive infrared thermal imager. Background Art

[0002] When enforcing the law, police officers sometimes need to observe the inside of suspicious rooms or enclosed spaces through narrow gaps such as door cracks. Due to the particularity of police operations, the observation environment is usually dim, and infrared light sources that are invisible to the naked eye are needed for supplementary lighting.

[0003] For example, the utility model patent with application number CN202323138654.4 discloses a narrow-slit infrared night vision device, including an operating mechanism, a traction rope connected to the operating mechanism, a curved portion provided at the end of the traction rope, and a night vision probe provided at the end of the curved portion. The front end of the operating mechanism is provided with an insertion tube, the traction rope passes through the insertion tube and is connected to the curved portion. The night vision probe includes a shell, a camera provided in the middle of the shell, at least one infrared LED lamp provided on one side of the camera, and an optical fiber provided on one side of the camera. The shell is provided with an optical fiber light outlet at a position corresponding to the optical fiber.

[0004] In the above case, when observing a narrow gap such as a door crack, you need to first hold the night vision probe, then bend down and insert the night vision probe into the door crack. After inserting the night vision probe, stand up and use the operating mechanism to adjust the angle of the night vision probe to observe the indoor situation. If you need to adjust the penetration distance of the night vision probe, you need to bend down again and pull the optical fiber of the night vision probe to make the night vision probe go deeper or leave the door crack.

[0005] In summary, in the prior art, when using an infrared thermal imager to observe door gaps, one often needs to constantly bend over to adjust the depth of the probe, which on the one hand increases labor intensity, and on the other hand, during the adjustment process, the probe will rub against the ground, which can easily cause damage to the probe.

[0006] Therefore, the present invention proposes a narrow-slit adaptive infrared thermal imager to solve the above problems. Summary of the Invention

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a narrow-slit adaptive infrared thermal imager, comprising:

[0008] A bracket, wherein the bottom end of the bracket is symmetrically connected to a rotating plate, and the ends of the two rotating plates are fixedly connected to a fixed shell;

[0009] An operating panel is fixedly connected to the top of the bracket, and a display screen and an operating lever are provided on the top surface of the operating panel;

[0010] An optical fiber, wherein the top end of the optical fiber is fixedly connected to the operation panel, the bottom end of the optical fiber passes through the fixed housing and is slidably connected to the fixed housing, and the bottom end of the optical fiber is fixedly connected to the probe;

[0011] The flip adjustment component is used to drive the rotating plate to rotate to adjust the angle of the fixed shell so that the fixed shell is parallel to the ground.

[0012] Preferably, the flip adjustment component includes:

[0013] Two first gears, the two first gears are coaxially fixed to the two rotating plates respectively;

[0014] Two first rack plates, the bottom ends of the two first rack plates are respectively engaged with the two first gears, and the top ends of the two first rack plates pass through the bottom end of the bracket and are slidably connected in the bracket;

[0015] The pushing assembly is used to push the first rack plate so that the first rack plate slides along the bracket, thereby driving the first gear to rotate and causing the rotating plate to flip.

[0016] Preferably, the pushing assembly includes:

[0017] a first adjusting knob, wherein the first adjusting knob is threadedly connected to the outer side wall of the bracket;

[0018] Two slide grooves, the two slide grooves are symmetrically opened on the outer side wall of the bracket;

[0019] The top ends of the two first rack plates are fixedly connected to a connecting plate, the connecting plate is slidably connected in the sliding groove, and the end of the connecting plate is rotatably connected to the inner wall of the first adjusting button.

[0020] Specifically, when the probe needs to be inserted into the door gap, the bracket is first placed on the ground, and the bracket is tilted according to preference. Then, the first adjustment knob is turned. Under the action of the threaded connection, the first adjustment knob moves upward, so that the first rack plate moves upward, thereby driving the first gear to rotate. Since the first gear is coaxially fixed with the rotating plate, when the first gear rotates, the rotating plate drives the fixed shell to rotate synchronously, so that the fixed shell is finally parallel to the bottom surface and in contact with the ground;

[0021] After the adjustment is completed, the bracket is pushed to move horizontally closer to the door body, so that the fixed shell drives the probe to be inserted into the door gap. Since the probe is supported by the fixed shell, there is a certain distance between the bottom of the probe and the ground, which is conducive to reducing the wear of the probe on the ground during the process of inserting the probe into the door gap;

[0022] After the probe completes detection of the room, the bracket is moved horizontally away from the door body, so that the fixed shell drives the probe out of the door gap. There is no need to bend back and forth to pick up the probe, insert the probe into or remove it from the door gap, thereby reducing the difficulty of use.

[0023] Preferably, it also includes:

[0024] Four transmission rollers, the four transmission rollers are symmetrically rotatably connected in the fixed housing;

[0025] Two conveyor belts, both ends of the two conveyor belts are respectively connected to the surfaces of two transmission rollers;

[0026] The rotary drive mechanism is used to drive the transmission roller to rotate, so as to drive the conveyor belt to transmit and adjust the penetration distance of the optical fiber.

[0027] Preferably, the rotation drive mechanism includes:

[0028] Two second gears, the two second gears are coaxially fixed to the transmission roller;

[0029] Two second rack plates, the two second rack plates are slidably connected to the side walls of the rotating plate, and the ends of the second rack plates penetrate the fixed housing and mesh with the second gear;

[0030] The pushing mechanism is used to push the second rack plate so that the second rack plate is engaged with the second gear.

[0031] Preferably, the pushing mechanism includes:

[0032] Two cylinders, the two cylinders are symmetrically fixedly connected to the side walls of the two rotating plates, and the telescopic rods of the cylinders are fixedly connected to the second rack plates at corresponding positions;

[0033] An annular mounting shell, the annular mounting shell is fixedly connected to the outer side wall of the bracket, and the annular mounting shell is internally threaded with a second adjusting button;

[0034] An air pipe, one end of which is fixedly connected to the cylinder body of the cylinder, and the other end of which is fixedly communicated with the inside of the annular mounting shell.

[0035] Specifically, when the probe needs to be further inserted into the door gap, the second adjusting knob is turned. Under the action of the threaded connection, the second adjusting knob moves downward, so that the gas in the annular mounting shell is compressed. The gas in the annular mounting shell enters the cylinder body of the cylinder through the air pipe. Under the action of pressure, the telescopic rod of the cylinder pushes the second rack plate, so that the second rack plate penetrates into the fixed shell and meshes with the second gear. The second gear rotates, thereby rotating the transmission roller, moving the two conveyor belts, and then driving the optical fiber to move, so that the optical fiber drives the probe to penetrate deeper, thereby increasing the penetration distance.

[0036] If the penetration distance of the probe needs to be reduced, the second adjusting knob is rotated in the reverse direction to generate negative pressure in the annular mounting shell, so that the telescopic rod of the cylinder pulls the second rack plate, causing the second gear to rotate in the reverse direction, thereby causing the conveyor belt to drive in the reverse direction, and the optical fiber drives the probe to move, thereby reducing the penetration distance.

[0037] Preferably, it also includes:

[0038] A U-shaped support frame, wherein both sides of the U-shaped support frame are slidably connected to both sides of the fixed shell, the top of the U-shaped support frame is fixedly connected to an arc-shaped fixing plate, and the optical fiber is fixedly connected in the arc-shaped fixing plate;

[0039] The fixed shell is symmetrically provided with guide grooves on both sides, and the guide grooves include oblique grooves and transverse grooves. The U-shaped support frame is symmetrically fixedly connected with sliding pins on both sides, and the sliding pins are slidably connected in the guide grooves.

[0040] Preferably, it also includes:

[0041] Two sliding frames are symmetrically and slidingly connected to the two sides of the fixed shell. Slide blocks are fixedly connected to the two sides of the U-shaped support frame, and the slide blocks are slidably connected in the sliding frames.

[0042] Preferably, it also includes:

[0043] The top of the support leg is rotatably connected to the outer side wall of the bracket.

[0044] Preferably, it also includes:

[0045] A plurality of guide rings are fixedly connected to the outer side wall of the bracket and are used for limiting the optical fiber.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1. The present invention pushes the bracket by providing a fixed shell and a rotating plate, so that the bracket moves horizontally close to the door body. On the one hand, there is no need to bend back and forth to pick up the probe and insert or remove the probe from the door gap, thereby reducing the difficulty of use. On the other hand, because the probe is supported by the fixed shell, there is a certain distance between the bottom of the probe and the ground, which is conducive to reducing the wear of the probe by the ground during the process of inserting the probe into the door gap.

[0048] 2. The present invention sets a conveyor belt. When it is necessary to make the probe go deeper into the door gap, the second adjusting knob is turned to compress the gas in the annular mounting shell. The gas in the annular mounting shell enters the cylinder body of the cylinder through the air pipe. Under the action of pressure, the telescopic rod of the cylinder pushes the second rack plate, so that the second rack plate goes deeper into the fixed shell and engages with the second gear. The second gear rotates, causing the two conveyor belts to move, and then driving the optical fiber to move, so that the optical fiber drives the probe to go deeper, thereby increasing the penetration distance.

[0049] 3. The present invention is arranged in a process where a conveyor belt pushes the optical fiber deep into the door gap. The optical fiber drives the U-shaped support frame to move, so that the U-shaped support frame moves along the guide groove. Driven by the inclined groove in the guide groove, the U-shaped support frame moves upward, so that the optical fiber drives the probe to move upward. On the one hand, the probe is further away from the ground, which is beneficial to reduce the wear of the probe by the ground. On the other hand, the height of the probe is increased, which is beneficial to adjust the shooting height. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0058] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0059] like Figures 1 to 7 The narrow-slit adaptive infrared thermal imager shown includes:

[0060] Bracket 1, the bottom end of bracket 1 is symmetrically connected to a rotating plate 2, and the ends of the two rotating plates 2 are fixedly connected to a fixed shell 3;

[0061] The operation panel 5 is fixedly connected to the top of the bracket 1, and the top surface of the operation panel 5 is provided with a display screen 6 and an operating lever 7;

[0062] Optical fiber 10, the top end of the optical fiber 10 is fixedly connected to the operation panel 5, the bottom end of the optical fiber 10 passes through the fixed housing 3 and is slidably connected to the fixed housing 3, and the bottom end of the optical fiber 10 is fixedly connected to the probe 11;

[0063] The flip adjustment component is used to drive the rotating plate 2 to rotate to adjust the angle of the fixed shell 3 so that the fixed shell 3 is parallel to the ground;

[0064] The tilt adjustment assembly includes:

[0065] Two first gears 12, the two first gears 12 are coaxially fixed to the two rotating plates 2 respectively;

[0066] Two first rack plates 13, the bottom ends of the two first rack plates 13 are respectively engaged with the two first gears 12, and the top ends of the two first rack plates 13 pass through the bottom end of the bracket 1 and are slidably connected in the bracket 1;

[0067] A pushing assembly is used to push the first rack plate 13 so that the first rack plate 13 slides along the inside of the bracket 1, thereby driving the first gear 12 to rotate and causing the rotating plate 2 to flip;

[0068] The push components include:

[0069] A first adjusting button 14, which is threadedly connected to the outer wall of the bracket 1;

[0070] Two chutes 15, the two chutes 15 are symmetrically opened on the outer side wall of the bracket 1;

[0071] The top ends of the two first rack plates 13 are fixedly connected to a connecting plate 16 , which is slidably connected to the slide groove 15 , and the ends of the connecting plates 16 are rotatably connected to the inner wall of the first adjusting button 14 ;

[0072] Specifically, in the prior art, when using an infrared thermal imager to observe the door gap, it is often necessary to constantly bend down to adjust the depth of the probe 11. On the one hand, this increases labor intensity. On the other hand, during the adjustment process, the probe 11 will rub against the ground, which can easily cause damage to the probe 11. This technical solution can solve the above problems. The specific operation is as follows:

[0073] When the probe 11 needs to be inserted into the door gap, the bracket 1 is first placed on the ground and tilted according to preference. Then, the first adjusting button 14 is turned. Under the action of the threaded connection, the first adjusting button 14 moves upward, which causes the first rack plate 13 to move upward, thereby driving the first gear 12 to rotate. Since the first gear 12 is coaxially fixed with the rotating plate 2, when the first gear 12 rotates, the rotating plate 2 drives the fixed housing 3 to rotate synchronously, thereby finally making the fixed housing 3 parallel to the bottom surface and in contact with the ground;

[0074] After the adjustment is completed, the bracket 1 is pushed to move the bracket 1 horizontally close to the door body, so that the fixed shell 3 drives the probe 11 to be inserted into the door gap. Since the probe 11 is supported by the fixed shell 3, there is a certain distance between the bottom of the probe 11 and the ground, which helps to reduce the wear of the probe 11 by the ground during the process of inserting the probe 11 into the door gap;

[0075] After the probe 11 completes detection of the room, the bracket 1 is moved horizontally away from the door body, so that the fixed shell 3 drives the probe 11 out of the door gap. There is no need to bend back and forth to pick up the probe 11, insert the probe 11 into or remove it from the door gap, thereby reducing the difficulty of use.

[0076] It should be noted that the direction of the probe 11 can be adjusted by the operating rod 7. The specific principle can be referred to the endoscope and will not be described in detail here.

[0077] Further explanation: After the probe 11 is removed from the door gap, the first rack plate 13 is reset by rotating the first adjusting button 14, so that the rotating plate 2 drives the fixed shell 3 to flip, so that the probe 11 faces upward. Compared with the probe 11 facing downward, this is beneficial to reduce damage to the probe 11 during the moving bracket 1.

[0078] It should also be noted that since the first adjusting button 14 is connected to the bracket 1 by a threaded connection, it is beneficial to improve the stability of the rotating plate 2 after it is turned over.

[0079] The probe 11 is provided with an infrared thermal imaging head and an optical lens.

[0080] As a further embodiment of the present invention, it also includes:

[0081] Four transmission rollers 17, the four transmission rollers 17 are symmetrically connected to the fixed shell 3;

[0082] Two conveyor belts 18, both ends of the two conveyor belts 18 are respectively connected to the surfaces of two transmission rollers 17;

[0083] The rotary drive mechanism is used to drive the transmission roller 17 to rotate, so as to drive the conveyor belt 18 to transmit and adjust the depth of the optical fiber 10;

[0084] The rotary drive mechanism includes:

[0085] Two second gears 19, the two second gears 19 are coaxially fixed to the transmission roller 17;

[0086] Two second rack plates 20, the two second rack plates 20 are slidably connected to the side walls of the rotating plate 2, and the ends of the second rack plates 20 pass through the fixed housing 3 and engage with the second gear 19;

[0087] A pushing mechanism is used to push the second rack plate 20 so that the second rack plate 20 is engaged with the second gear 19;

[0088] The driving agencies include:

[0089] Two cylinders 21, the two cylinders 21 are symmetrically fixedly connected to the side walls of the two rotating plates 2, and the telescopic rods of the cylinders 21 are fixedly connected to the second rack plates 20 at corresponding positions;

[0090] An annular mounting shell 22 is fixedly connected to the outer wall of the bracket 1, and a second adjusting button 23 is connected to the inner thread of the annular mounting shell 22;

[0091] An air pipe 24, one end of which is fixedly connected to the cylinder body of the air cylinder 21, and the other end of which is fixedly connected to the inside of the annular mounting shell 22;

[0092] Specifically, when the probe 11 needs to be further inserted into the door gap, the second adjusting button 23 is rotated. Under the action of the threaded connection, the second adjusting button 23 moves downward, so that the gas in the annular mounting shell 22 is compressed. The gas in the annular mounting shell 22 enters the cylinder body of the cylinder 21 through the air pipe 24. Under the action of pressure, the telescopic rod of the cylinder 21 pushes the second rack plate 20, so that the second rack plate 20 penetrates into the fixed shell 3 and meshes with the second gear 19. The second gear 19 rotates, thereby rotating the transmission roller 17, causing the two conveyor belts 18 to move, and then driving the optical fiber 10 to move, so that the optical fiber 10 drives the probe 11 to penetrate deeper, thereby increasing the penetration distance;

[0093] If it is necessary to reduce the penetration distance of the probe 11, the second adjusting knob 23 is rotated in the reverse direction to generate negative pressure in the annular mounting shell 22, so that the telescopic rod of the cylinder 21 pulls the second rack plate 20, causing the second gear 19 to rotate in the reverse direction, thereby causing the conveyor belt 18 to drive in the reverse direction, and the optical fiber 10 drives the probe 11 to move, thereby reducing the penetration distance.

[0094] As a further embodiment of the present invention, it also includes:

[0095] A U-shaped support frame 25 is slidably connected to both sides of the fixed shell 3. The top of the U-shaped support frame 25 is fixedly connected to an arc-shaped fixing plate 27. The optical fiber 10 is fixedly connected to the arc-shaped fixing plate 27.

[0096] The fixed shell 3 is symmetrically provided with guide grooves 4 on both sides. The guide grooves 4 include oblique grooves and transverse grooves. The U-shaped support frame 25 is symmetrically fixedly connected with sliding pins on both sides. The sliding pins are slidably connected in the guide grooves 4.

[0097] Two sliding frames 26 are symmetrically slidably connected to both sides of the fixed shell 3. Sliders are fixedly connected to both sides of the U-shaped support frame 25, and the slides are slidably connected in the sliding frames 26;

[0098] Specifically, as the conveyor belt 18 pushes the optical fiber 10 deeper into the door gap, the optical fiber 10 drives the U-shaped support frame 25 to move, causing the U-shaped support frame 25 to move along the guide groove 4. Driven by the inclined groove in the guide groove 4, the U-shaped support frame 25 moves upward, causing the optical fiber 10 to drive the probe 11 upward. On the one hand, this moves the probe 11 further away from the ground, thereby reducing the wear of the probe 11 by the ground. On the other hand, it increases the height of the probe 11, which is conducive to adjusting the shooting height. (Compared to adjusting the angle of the probe 11 by the operating lever 7, this adjustment can make the probe 11 and the ground surface, so that the shooting angle of the probe 11 is in a horizontal state, thereby making the captured image horizontal.)

[0099] As a further embodiment of the present invention, it also includes:

[0100] The support legs 8 are rotatably connected to the outer wall of the bracket 1 at their top ends, so that the bracket 1 can stand stably on the ground without manual support.

[0101] As a further embodiment of the present invention, it also includes:

[0102] Several guide rings 9 are fixedly connected to the outer wall of the bracket 1 and are used to limit the optical fiber 10 to prevent the optical fiber 10 from being entangled.

[0103] The working principle of the present invention is as follows: when the probe 11 needs to be inserted into the door gap, the bracket 1 is first placed on the ground and tilted according to preference. Then, the first adjustment button 14 is rotated. Under the action of the threaded connection, the first adjustment button 14 moves upward, causing the first rack plate 13 to move upward, thereby driving the first gear 12 to rotate. Since the first gear 12 is coaxially fixed with the rotating plate 2, when the first gear 12 rotates, the rotating plate 2 drives the fixed housing 3 to rotate synchronously, thereby ultimately making the fixed housing 3 parallel to the bottom surface and in contact with the ground;

[0104] After the adjustment is completed, the bracket 1 is pushed to move the bracket 1 horizontally close to the door body, so that the fixed shell 3 drives the probe 11 to be inserted into the door gap. Since the probe 11 is supported by the fixed shell 3, there is a certain distance between the bottom of the probe 11 and the ground, which helps to reduce the wear of the probe 11 by the ground during the process of inserting the probe 11 into the door gap;

[0105] After the probe 11 completes detection of the room, the bracket 1 is moved horizontally away from the door body, so that the fixed shell 3 drives the probe 11 out of the door gap. There is no need to bend back and forth to pick up the probe 11, insert the probe 11 into or remove it from the door gap, thereby reducing the difficulty of use.

[0106] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the invention as claimed.
