Description

Technical Field

[0001] The present application relates to the field of detection devices, and in particular to a portable detection camera. Background Art

[0002] When inspecting or observing locations with small available gaps such as wall gaps and lines, it is usually necessary to use a miniature camera for observation.

[0003] The micro camera is connected to the end of the hose, and a data cable is connected to the other end of the hose. The data cable is used to connect the micro camera and the mobile phone. At this time, the micro camera can transmit the image signal to the mobile phone so that the workers can directly observe the image taken by the micro camera.

[0004] In actual use, the shooting range of the miniature camera installed at the end of the hose is relatively limited. When it is necessary to observe the inner wall of the slit, the worker needs to adjust the angle of the hose so that the miniature camera is opposite to the inner wall of the slit. However, the operating space of the slit is small, which is not conducive to the worker adjusting the angle of the hose, thereby affecting the worker's observation and detection of the internal situation of the slit, so it needs to be improved. Utility Model Content

[0005] In order to improve the above problems, the present application provides a portable detection camera.

[0006] The present application provides a portable detection camera, which adopts the following technical solution:

[0007] A portable detection camera comprises a miniature camera and a light-transmitting hose, wherein one side of the light-transmitting hose is connected to the miniature camera and the other side is connected to a mounting plate, an optical fiber for providing a light source is provided on the side of the miniature camera close to the mounting plate, and a conical mirror matching the optical fiber is provided on the side of the mounting plate close to the miniature camera.

[0008] By adopting the above technical solution, when the slit needs to be detected, the optical fiber provides a light source, and the conical mirror refracts and reflects the light source, so that the light source passes through the light-transmitting hose. At this time, the image of the inner wall of the slit can be imaged on the conical mirror, and the micro camera receives the image on the conical mirror, realizing the function of panoramic detection of the slit, thereby increasing the detection range of the detection camera.

[0009] Preferably, a threaded ring is provided on one side of the miniature camera close to the mounting plate, and the inner wall of the light-transmitting hose is threadably connected to the outer wall of the threaded ring.

[0010] By adopting the above technical solution, workers abut the inner wall of the light-transmitting hose against the outer wall of the threaded ring and rotate the light-transmitting hose so that the light-transmitting hose is threadedly connected with the threaded ring. After the light-transmitting hose abuts against the miniature camera, the connection between the light-transmitting hose and the miniature camera is completed, thereby providing convenience for workers to install the light-transmitting hose.

[0011] Preferably, a sealing ring is provided on the outer wall of the threaded ring, and a ring groove matching with the sealing ring is provided on the inner wall of the light-transmitting hose, and the side of the sealing ring facing away from the threaded ring extends into the ring groove.

[0012] By adopting the above technical solution, the sealing ring increases the sealing between the light-transmitting hose and the threaded ring, and reduces the possibility of external impurities entering the light-transmitting hose, so that the conical mirror can more accurately image the inner wall of the slit.

[0013] Preferably, a slot is provided on a side of the mounting plate close to the micro camera, and the conical mirror is arranged in the slot.

[0014] By adopting the above technical solution, when the conical mirror needs to be installed, the worker inserts the conical mirror into the slot so that the conical mirror abuts against the inner wall of the slot. At this time, the slot limits the conical mirror to complete the fixation between the conical mirror and the mounting plate.

[0015] Preferably, the inner wall of the slot is provided with a plurality of friction-increasing protrusions, and each of the friction-increasing protrusions abuts against the conical mirror.

[0016] By adopting the above technical solution, the friction-increasing protrusion increases the contact area between the mounting plate and the conical mirror, and further limits the conical mirror, thereby further improving the connection stability between the conical mirror and the mounting plate.

[0017] Preferably, a first plug-in ring is provided on one side of the mounting plate close to the light-transmitting hose, a first slot is provided on one side of the light-transmitting hose close to the mounting plate, and the first plug-in ring is arranged in the first slot.

[0018] By adopting the above technical solution, when it is necessary to connect the mounting plate and the light-transmitting hose, the worker aligns the first plug-in ring with the first slot, and then inserts the first plug-in ring into the first slot, so that the first plug-in ring abuts against the inner wall of the first slot. When the mounting plate abuts against the light-transmitting hose, the installation between the mounting plate and the light-transmitting hose can be completed, thereby providing convenience for the workers to fix the mounting plate.

[0019] Preferably, a second plug-in ring is provided on the outer side of the first plug-in ring, a second slot is provided on the inner wall of the first slot, and the second plug-in ring is arranged in the second slot.

[0020] By adopting the above technical solution, the second plug-in ring cooperates with the second slot to increase the contact area between the mounting plate and the light-transmitting hose. At the same time, the second plug-in ring provides a limit for the first plug-in ring, making it difficult for the first plug-in ring to separate from the first slot, thereby reducing the possibility of separation between the mounting plate and the light-transmitting hose, thereby improving the connection stability between the mounting plate and the light-transmitting hose.

[0021] Preferably, a clearance groove is formed on a side of the mounting plate away from the light-transmitting hose, and a handle is provided in the clearance groove.

[0022] By adopting the above technical solution, when a worker needs to separate the mounting plate and the light-transmitting hose, the worker pulls the handle in the direction away from the light-transmitting hose, and the handle provides a fulcrum for the worker to move the mounting plate. The handle then drives the mounting plate to move in the direction away from the light-transmitting hose, and after the first plug-in ring is separated from the inner wall of the first slot, the mounting plate and the light-transmitting hose can be separated, thereby providing convenience for the worker to disassemble the mounting plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By arranging a light-transmitting hose, an optical fiber and a conical mirror, the optical fiber provides a light source. Under the action of the conical mirror, the light source passes through the light-transmitting hose to image the inner wall of the slit onto the conical mirror. The micro camera can collect the image formed on the conical mirror, realizing the function of panoramic observation of the slit, thereby improving the detection range of the detection camera;

[0025] 2. By setting the threaded ring, the threaded ring is convenient for workers to install the light-transmitting hose on the miniature camera, so that workers can install and disassemble the light-transmitting hose;

[0026] 3. By setting a sealing ring, the sealing ring increases the sealing ability between the light-transmitting hose and the threaded ring, reducing the possibility of external impurities entering the light-transmitting hose and affecting the accuracy of the image formed on the conical mirror, so that the detection camera can detect the slit more stably.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a portable detection camera. Figure 1 and Figure 2 A portable detection camera includes a miniature camera 1 and a light-transmitting hose 2, one end of the light-transmitting hose 2 is connected to the miniature camera 1, and the other end is connected to a mounting plate 3, an optical fiber 4 for providing a light source is provided on the side of the miniature camera 1 close to the mounting plate 3, and a conical mirror 5 matching the optical fiber 4 and the miniature camera 1 is provided on the side of the mounting plate 3 close to the miniature camera 1.

[0033] When the detection camera is in use, the optical fiber 4 provides a light source, and the conical mirror 5 refracts and reflects the light source, so that the light source passes through the light-transmitting hose 2 to form an image of the inner wall of the slit on the conical mirror 5. At this time, the micro camera 1 can receive the image on the conical mirror 5, realizing the function of panoramic observation of the slit, thereby improving the detection range of the detection camera.

[0034] Reference Figure 2 In order to facilitate the installation of the light-transmitting hose 2, a threaded ring 11 is fixed on the side of the miniature camera 1 close to the mounting plate 3, and the inner wall of the light-transmitting hose 2 is threadedly connected to the outer wall of the threaded ring 11. A sealing ring 111 is fixed on the outer wall of the threaded ring 11, and a ring groove 21 matching the sealing ring 111 is formed on the inner wall of the light-transmitting hose 2, and the side of the sealing ring 111 facing away from the threaded ring 11 extends into the ring groove 21. The light-transmitting hose 2 is configured as a plastic hose so that the light-transmitting hose 2 can adapt to the environment in the slit, and at the same time, it is convenient for the light source to pass through the light-transmitting hose 2 more stably.

[0035] When the light-transmitting hose 2 needs to be installed, the worker abuts the inner wall of the light-transmitting hose 2 against the outer wall of the threaded ring 11 and rotates the light-transmitting hose 2, so that the light-transmitting hose 2 is threadedly connected with the threaded ring 11. When the inner wall of the light-transmitting hose 2 contacts the sealing ring 111, the light-transmitting hose 2 undergoes elastic deformation. When the sealing ring 111 is opposite to the annular groove 21, the sealing ring 111 can be inserted into the annular groove 21 and abut against the inner wall of the annular groove 21, and the light-transmitting hose 2 abuts against the miniature camera 1, completing the installation between the light-transmitting hose 2 and the miniature camera 1, thereby providing convenience for the worker to use the light-transmitting hose 2. At the same time, the sealing ring 111 increases the sealing between the light-transmitting hose 2 and the threaded ring 11, that is, the sealing between the light-transmitting hose 2 and the miniature camera 1, so that foreign impurities are not easy to enter the light-transmitting hose 2, and the possibility of imaging errors on the conical mirror 5 is reduced, so that the detection camera can detect the slit more stably.

[0036] Reference Figure 1 and Figure 3 In order to facilitate the installation of the conical mirror 5, a slot 31 is provided on one side of the mounting plate 3 close to the light-transmitting hose 2, and the conical mirror 5 is arranged in the slot 31. A plurality of friction-increasing protrusions 311 are fixed to the inner wall of the slot 31, each of which is in contact with the conical mirror 5, and each of which is provided with a friction-increasing tooth surface 312.

[0037] The worker inserts the conical mirror 5 into the slot 31. At this time, the friction-increasing tooth surfaces 312 on each friction-increasing protrusion 311 abut against the conical mirror 5, increasing the friction between the friction-increasing protrusion 311 and the conical mirror 5, making it difficult for the conical mirror 5 to fall out of the slot 31. On the one hand, it provides convenience for the workers to install the conical mirror 5, and on the other hand, it improves the stability of the conical mirror 5 during subsequent work.

[0038] Reference Figure 1 and Figure 2 In order to facilitate the installation of the mounting plate 3 , a first plug ring 32 is fixed to the side of the mounting plate 3 close to the light-transmitting hose 2 , and a first slot 22 is opened on the side of the light-transmitting hose 2 close to the mounting plate 3 , and the first plug ring 32 is arranged in the first slot 22 .

[0039] A second plug-in ring 33 is fixed to the outer side of the first plug-in ring 32 , a second slot 23 is formed on the inner wall of the first slot 22 , and the second plug-in ring 33 is disposed in the second slot 23 .

[0040] After the worker fixes the conical mirror 5 on the mounting plate 3, the worker places the first plug-in ring 32 opposite to the first slot 22 to insert the first plug-in ring 32 into the first slot 22. When the second plug-in ring 33 contacts the inner wall of the first slot 22, the inner wall of the first slot 22 undergoes elastic deformation. When the second plug-in ring 33 is opposite to the inner wall of the second slot 23, the second plug-in ring 33 is inserted into the second slot 23, and the inner wall of the first slot 22 recovers its deformation and abuts against the first plug-in ring 32, and the mounting plate 3 abuts against the end of the light-transmitting hose 2 away from the miniature camera 1, completing the fixing between the mounting plate 3 and the light-transmitting hose 2. Under the action of the second plug-in ring 33, a limit is provided for the first plug-in ring 32 and the mounting plate 3, so that the mounting plate 3 is not easily separated from the light-transmitting hose 2 when in use.

[0041] Reference Figure 2 In order to facilitate the replacement of the mounting plate 3, a clearance groove 34 is provided on the side of the mounting plate 3 away from the light-transmitting hose 2, and a handle 341 is fixed in the clearance groove 34. The worker pulls the handle 341 in the direction away from the light-transmitting hose 2, and the handle 341 drives the mounting plate 3 to move, so that the second plug-in ring 33 is gradually separated from the second slot 23. After the first plug-in ring 32 is separated from the first slot 22, the disassembly between the mounting plate 3 and the light-transmitting hose 2 can be completed, thereby facilitating the installation and disassembly of the mounting plate 3.

[0042] Reference Figure 2 In order to facilitate the light-transmitting hose 2 and the mounting plate 3 to adapt to the environment of the slit, a guide arc surface 35 is provided on the side of the mounting plate 3 away from the light-transmitting hose 2. The guide arc surface 35 provides guidance for the mounting plate 3 when the mounting plate 3 moves, thereby reducing the reaction force of the protrusions or impurities on the inner wall of the slit on the mounting plate 3, making it difficult for the mounting plate 3 to separate from the light-transmitting hose 2 during the movement, so that the conical mirror 5 can more stably form the image of the inner wall of the slit.

[0043] The implementation principle of a portable detection camera in an embodiment of the present application is as follows: the optical fiber 4 provides a light source for the conical mirror 5. Under the reflection and refraction of the conical mirror 5, the light source passes through the light-transmitting hose 2 to image the scene on the inner wall of the slit on the conical mirror 5. The micro camera 1 can receive the image formed on the conical mirror 5, realizing the function of panoramic observation of the slit, thereby increasing the detection range of the detection camera.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
