Description

Technical Field

[0001] This utility model relates to an evidence collection and photography device, and more particularly to a multi-light source evidence collection and floating photography device, belonging to the field of multispectral photographic evidence collection technology. Background Technology

[0002] Photographing physical evidence, traces at crime scenes, and forgeries has always been an important task for forensic scientists and police officers. Traditional methods of evidence collection, especially for complex cases or items, often require specialized laboratories for chemical analysis or microscopic examination, which is time-consuming and labor-intensive. The application of multispectral (multi-light source) photographic evidence collection systems has greatly improved the effectiveness and accuracy of law enforcement.

[0003] Multispectral photographic forensics systems are high-resolution, multi-band, high-speed, and highly interference-resistant imaging systems that capture more details and information, helping law enforcement officers quickly and accurately analyze evidence. They can significantly shorten evidence collection time, improve law enforcement efficiency, and rapidly identify different materials and compositions through multi-wavelength imaging. The system is also highly resistant to interference, operating even in complex environments such as under fluorescent lights and strong sunlight. By simplifying imaging through multispectral imaging, it supports image capture, processing, and analysis across various application areas. Thanks to its non-invasive and non-destructive analytical characteristics, multispectral solutions are an excellent choice for cultural heritage projects, police / forensic evidence collection, and industrial applications.

[0004] Multispectral photographic evidence collection systems (devices) typically consist of a bracket that carries a multispectral light source and a camera. However, existing multispectral photographic evidence collection devices suffer from drawbacks such as inconvenience in adjustment, difficulty in extending and suspending, and inability to flexibly choose whether to place them on the ground or clamp them onto a table, which affect their usability. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a multi-light source evidence collection and floating photography device.

[0006] The technical solution adopted in this utility model is as follows: a multi-light source evidence-gathering suspended photography device is designed, which includes a support, a suspended arm, a universal adapter, a multispectral light source, and a camera; the suspended arm is mounted on the support, and the suspended arm adopts a folding universal bracket. The universal adapter is located at the end of the suspended arm away from the support, and the multispectral light source and camera are mounted on the universal adapter. The support supports the overall structure, the suspended arm can adjust and extend the multispectral light source and camera laterally to achieve the effect of suspended shooting at a distance, and the universal adapter can adjust the angle of the multispectral light source and camera to achieve flexible shooting.

[0007] The support includes a telescopic arm and a clamping mechanism. When the telescopic arm is extended horizontally, the support can be placed on the ground. When the telescopic arm is retracted horizontally, the support can be clamped in place by the clamping mechanism. This multi-functional support allows the multi-light source evidence-gathering suspended photography device to be used either on the ground or clamped onto a high platform, depending on the shooting environment. Changing the fixing method does not require replacing the support, making it more convenient and practical.

[0008] Furthermore, the support also includes a column, the lower end of which is provided with an integrated ring. At least three sets of telescopic arms are arranged in a circumferential array on the integrated ring, making it easier to install the telescopic arms. Each telescopic arm includes a first support rod, a second support rod, and a third support rod. The first support rod is mounted on the integrated ring, the second support rod is slidably connected to the first support rod, and the third support rod is slidably connected to the second support rod. The extension of the three support rods greatly expands the extendable length of the arms, improving stability when placed on the ground. At the same time, the arms are not excessively long when retracted, which is beneficial for use with clamping mechanisms and makes storage more convenient. After the telescopic arms are retracted, the third support rod is stored inside the second support rod, and the second support rod is stored inside the first support rod.

[0009] Furthermore, the integrated ring is provided with a first C-shaped buckle, and the telescopic arm is connected to the integrated ring through the first C-shaped buckle. The first support rod of the telescopic arm is hinged to the first C-shaped buckle. After hinge, the first support rod can rotate within a 90° range between the first C-shaped buckle and the integrated ring and can be fixed to the first C-shaped buckle by a pin. After the telescopic arm is retracted, it can also rotate downwards to further reduce its space occupation and facilitate storage.

[0010] Furthermore, the first, second, and third support rods are all C-shaped plates, and when the telescopic arm is pulled out horizontally, the lower surfaces of the three are flush, providing a large support surface and more stable support.

[0011] Furthermore, the first support rod is provided with first sliding grooves on its left and right sides and top side, the second support rod is provided with sliders that are slidably connected to the first sliding grooves on its left and right sides and top side, and is also provided with second sliding grooves on its left and right sides and top side, and the third support rod is provided with sliders that are slidably connected to the second sliding grooves on its left and right sides and top side, so that the sliding connection is reliable.

[0012] Furthermore, the support also includes a quick-release pin. The first C-shaped buckle and the third support rod are provided with corresponding pin holes. The quick-release pin passes through the pin holes, the first slide groove and the second slide groove to fix the retracted telescopic support arm. On the one hand, it prevents the telescopic support arm from being accidentally extended or loosened. On the other hand, it can cooperate with the clamping mechanism to form a clamp.

[0013] Furthermore, the telescopic arm also includes a suction cup, which is hinged to the outer end of the third support rod. The suction cup adheres to the ground, improving the stability of the support when it is placed on the ground for support.

[0014] Furthermore, the clamping mechanism includes a pressure cylinder, a slide block, and a clamping rod. The lower part of the column is provided with an external thread. The pressure cylinder is threadedly connected to the column. The slide block is slidably disposed on the column body between the pressure cylinder and the integrated ring. The clamping rod is disposed on the slide block. After the telescopic arm retracts, the pressure cylinder presses down on the slide block, and the clamping rod, together with the first support rod, achieves clamping. When the support is used to clamp a tabletop, the clamping rod and the first support rod are placed on the upper and lower sides of the tabletop, respectively. By rotating the pressure cylinder downwards or upwards, the clamping rod can be pressed or released, thereby clamping or releasing the tabletop.

[0015] Furthermore, the clamping mechanism also includes a second C-shaped buckle, which is disposed on the slide. The clamping rod is hinged to the second C-shaped buckle. When not in use, the clamping rod can rotate downwards under its own weight to be parallel to the column for easy storage. The clamping rod is a rectangular tube with high structural strength, and its lower surface is flush with the lower surface of the second C-shaped buckle to achieve stable clamping.

[0016] Furthermore, the outer surface of the clamping cylinder is provided with densely packed strip-shaped protrusions arranged in a circumferential pattern to prevent slippage when rotating the clamping cylinder.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention features a suspended arm and universal adapter for easy adjustment, enabling the extension and suspension of multispectral light sources and cameras, thus improving the efficiency of evidence collection and photography. The telescopic support arm and clamping mechanism of the support allow for flexible placement of the multi-light source evidence collection and suspension photography device on the ground or clamped to a table as needed, reducing usage limitations.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1

[0028] like Figure 1-4As shown, a multi-light source evidence-gathering suspended photography device includes a support 1, a suspended arm 2, a universal adapter 3, a multispectral light source 4, and a camera (the camera is not shown in the attached figure, but it can generally be set on the structure of the multispectral light source 4, such as in its middle). The suspended arm 2 is fixedly mounted on the support 1. The suspended arm 2 adopts a folding universal bracket (a folding universal bracket of existing technology can be used). The universal adapter 3 (a universal adapter 3 of existing technology can be used) is set at the end of the suspended arm 2 away from the support 1. The multispectral light source 4 and the camera (a multispectral light source 4 and camera of existing technology can be used) are mounted on the universal adapter 3. For example, the multispectral light source 4 and the camera can be controlled by the user at close range or by a control system (using existing technology). It should be noted that the folding universal bracket, universal adapter 3, multispectral light source 4, and camera are all relatively lightweight structures. Although the telescopic arm 5 of the support 1 in the attached figure does not extend particularly long, it has been proven in practice (even without the suction cup 17 on the telescopic arm 5) to be sufficient for support. Furthermore, more stable support can be provided by adding weight to the support 1.

[0029] The support 1 includes a telescopic arm 5 and a clamping mechanism 6. When the telescopic arm 5 is pulled out horizontally, the support 1 can be placed on the ground. When the telescopic arm 5 is retracted horizontally, the support 1 can be clamped and placed by the clamping mechanism 6. Specifically, the support 1 also includes a column 7, with an integrated ring 8 at its lower end. At least three sets of the telescopic arms 5 are arranged in a circumferential array on the integrated ring 8. Each telescopic arm 5 includes a first support rod 9, a second support rod 10, and a third support rod 11. The first support rod 9 is disposed on the integrated ring 8, the second support rod 10 is slidably connected to the first support rod 9, and the third support rod 11 is slidably connected to the second support rod 10. More specifically, the first support rod 9 has a first sliding groove 13 on its left and right sides and top side, the second support rod 10 has sliders 14 slidably connected to the first sliding grooves 13 on its left and right sides and top side, and also has a second sliding groove 15. The third support rod 11 has sliders 14 slidably connected to the second sliding grooves 15 on its left and right sides and top side. After the telescopic arm 5 retracts, the third support rod 11 is housed inside the second support rod 10, and the second support rod 10 is housed inside the first support rod 9.

[0030] More specifically, the clamping mechanism 6 needs to be used in conjunction with the telescopic arm 5 to achieve clamping. The clamping mechanism 6 includes a pressure cylinder 18, a slide 19, and a clamping rod 20. The lower part of the column 7 is provided with a raised external thread. The pressure cylinder 18 is threadedly connected to the column 7 (i.e., the pressure cylinder 18 is provided with an internal thread corresponding to the external thread on the column 7). The slide 19 is slidably disposed on the column 7 between the pressure cylinder 18 and the integrated ring 8. The clamping rod 20 is disposed on the slide 19. After the telescopic arm 5 is retracted, the pressure cylinder 18 presses down on the slide 19, and the clamping rod 20 cooperates with the first support rod 9 to achieve clamping. More preferably, the clamping mechanism 6 also includes a second C-shaped buckle 21 (C-shaped plate). The second C-shaped buckle 21 is welded to the slide 19. The clamping rod 20 is hinged to the second C-shaped buckle 21. The clamping rod 20 is a rectangular tube, and its lower surface is flush with the lower surface of the second C-shaped buckle 21. When the clamping rod 20 is used for clamping, it rotates to a horizontal position and is then limited by the second C-shaped buckle 21, and is pressed tightly against the upper surface of the table to be clamped under the action of the clamping cylinder 18.

[0031] It should be noted that the slide 19 is a rotating cylinder, which can not only slide up and down along the column 7, but also rotate around the column 7, thereby achieving more flexible clamping. For example, the clamping rod 20 can be set opposite to the first support rod 9 of one set of telescopic support arms 5 to cooperate in clamping, or the clamping rod 20 can be used to cooperate with the first support rod 9 of two sets of telescopic support arms 5 for clamping. In this case, the first support rod 9 of the two sets of telescopic support arms 5 is attached to the lower surface of the table to be clamped, and the clamping rod 20 is attached to the upper surface of the table to be clamped, and is located on the left and right of the angle bisector of the first support rod 9 of the two sets of telescopic support arms 5.

[0032] Example 2

[0033] This embodiment further optimizes the structure of the support 1 based on embodiment 1. In this embodiment, the integrated ring 8 is provided with a first C-shaped buckle 12 (C-shaped plate), and the telescopic support arm 5 is connected to the integrated ring 8 through the first C-shaped buckle 12. The first support rod 9 of the telescopic support arm 5 is hinged to the first C-shaped buckle 12. After hinge, the first support rod 9 can rotate within a 90° range between the first C-shaped buckle 12 and the integrated ring 8 and can be fixed to the first C-shaped buckle 12 by a pin. More specifically, the support 1 also includes a quick-release pin 16. The first C-shaped buckle 12 and the third support rod 11 are provided with corresponding pin holes. The quick-release pin 16 passes through the pin holes, the first sliding groove 13 and the second sliding groove 15 to fix the retracted telescopic support arm 5.

[0034] In this embodiment, the first support rod 9, the second support rod 10, and the third support rod 11 are all C-shaped plates, and their lower surfaces are flush after the telescopic support arm 5 is pulled out horizontally. The telescopic support arm 5 also includes a suction cup 17 (a soft rubber suction cup 17), which is hinged to the outer end of the third support rod 11. The outer surface of the compression cylinder 18 is circumferentially provided with densely packed strip-shaped protrusions, which can also be anti-slip rubber sleeves.

[0035] When using this utility model, the telescopic arm 5 is usually pulled out and placed on the ground for use; in special cases, the telescopic arm 5 is retracted and locked with the quick-release pin 16, and then used in conjunction with the clamping rod to clamp the edge of a table or other structure for use.

[0036] Furthermore, in the description of this utility model, unless otherwise stated, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
