Description

Technical Field

[0001] This utility model relates to the field of criminal investigation equipment technology, specifically a focusing inspection table for handwriting identification. Background Technology

[0002] Handwriting identification refers to the identification and recognition of handwriting formed by a person through writing activities. By examining the handwriting, it can be determined how many people wrote the handwriting in the document, whether it was written by a certain person, and to verify the authenticity of the document by using handwriting to identify the person.

[0003] Currently, some handwriting identification work uses a standard testing table equipped with a spotlight. During this process, the handwriting sample and specimen are placed in separate transparent sealed bags. To facilitate observation, staff often hold the transparent plastic bag and adjust its position to find the best viewing angle for comparison and analysis. Since at least two samples or specimens need to be compared and their similarities and differences recorded, staff have to frequently switch hand movements between recording and adjusting the plastic bag. Maintaining this action for a long time not only leads to hand fatigue, but also requires staff to constantly adjust their body posture or move the samples and specimens to ensure the suitability of the viewing angle when the plastic bag is laid flat on the testing table. In view of this, we propose a new type of handwriting identification-specific spotlight testing table to solve the above problems. Utility Model Content

[0004] One of the technical problems this application aims to solve is: how to design a focusing inspection table for handwriting identification with an adjustable viewing angle to improve the efficiency and accuracy of handwriting identification.

[0005] To solve the above-mentioned technical problems, this application provides a focusing inspection table for handwriting identification, including a stage, and supporting legs are provided at the four corners of the bottom of the stage;

[0006] A first connector is disposed on the platform;

[0007] The second connector is connected to the first connector via a pivot.

[0008] A carrying plate is disposed on the second connecting member and is rotatably connected to the carrying platform through the second connecting member. A spotlight and a support plate are disposed on the carrying plate.

[0009] An adjustment component is disposed on the platform and is used to adjust the angle of the platform.

[0010] In some embodiments, the adjustment assembly includes a fourth connector disposed on the platform, a square clearance hole is provided on the platform, a pair of fixing members are provided at the bottom of the platform, a rotating member is rotatably connected to the pair of fixing members, a threaded rod is threadedly mounted on the rotating member, a manual turntable is fixed to one end of the threaded rod, a third connector is rotatably connected to the other end of the threaded rod, and one end of the third connector is rotatably connected to the fourth connector.

[0011] In some embodiments, the manual turntable is provided with anti-slip texture.

[0012] In some embodiments, there are two of the first connector and the second connector.

[0013] In some embodiments, the carrier plate is further provided with a pair of guide holes, and a connecting rod is slidably connected to each of the pair of guide holes. A fixing plate is threaded onto one end of the connecting rod, and a clamping plate is fixed to the other end of the connecting rod. A spring is sleeved on the outer wall of the connecting rod, one end of the spring abuts against the carrier plate, and the other end of the spring abuts against the fixing plate. A handle is provided on one side of the clamping plate.

[0014] In some embodiments, the width of the clamping piece is greater than the width of the guide hole.

[0015] In some embodiments, the length of the connecting rod is greater than the thickness of the carrier plate.

[0016] This utility model has at least the following beneficial effects:

[0017] 1. This utility model, by setting an adjustment component, allows manual rotation of a manual turntable, which in turn drives a threaded rod to rotate. The rotation of the threaded rod causes it to move up and down on a rotating component. The up and down movement of the threaded rod causes a third connecting component to move. The movement of the third connecting component causes the carrier plate to rotate around the axis between the second connecting component and the first connecting component, thereby realizing the adjustment of the angle of the carrier plate. This design allows staff to easily adjust the observation angle of the handwriting sample as needed without frequently switching hand movements or adjusting body posture, greatly improving the efficiency and accuracy of handwriting identification.

[0018] 2. By setting up a clamping mechanism, when the sample is placed on the support plate, the two connecting rods can be moved upward to the top of the sample. Then, the connecting rods are moved downward so that the outer wall of the connecting rods abuts against the top of the sample. The clamping piece tightly clamps the sample, thereby fixing the position of the sample. This design not only makes it easy for staff to quickly fix the sample, but also ensures stable clamping and prevents the sample from sliding or shifting when adjusting the observation angle, further improving the accuracy and efficiency of handwriting identification.

[0019] 3. This utility model increases the friction between the hand and the manual turntable by setting anti-slip texture, preventing the hand from slipping and improving the stability and accuracy of rotation. By setting two first connecting parts and a second connecting part, the stability of the carrying plate is ensured, making the carrying plate more stable when rotating and avoiding shaking.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-3 This utility model provides a technical solution: a focusing inspection table for handwriting identification, including a stage 1, with support legs 2 provided at the four corners of the bottom of the stage 1;

[0029] First connector 5, the first connector 5 is disposed on the stage 1;

[0030] The second connector 6 is connected to the first connector 5 via a pivot.

[0031] The loading plate 3 is mounted on the second connector 6 and is rotatably connected to the loading platform 1 via the second connector 6. The loading plate 3 is equipped with a spotlight 4 and a support plate 7.

[0032] Adjustment component 100 is disposed on stage 1 and is used to adjust the angle of the loading plate 3;

[0033] The adjustment assembly 100 includes a fourth connector 107 disposed on the platform 3. A square clearance hole 101 is provided on the platform 1. A pair of fixing members 102 are provided at the bottom of the platform 1. A rotating member 103 is rotatably connected to the pair of fixing members 102. A threaded rod 104 is threadedly installed on the rotating member 103. A manual turntable 105 is fixed to one end of the threaded rod 104. A third connector 106 is rotatably connected to the other end of the threaded rod 104. One end of the third connector 106 is rotatably connected to the fourth connector 107.

[0034] The manual turntable 105 is provided with anti-slip texture so that when the operator rotates the manual turntable 105, the friction between the hand and the manual turntable 105 can be increased, preventing the hand from slipping and improving the stability and accuracy of rotation.

[0035] There are two first connectors 5 and two second connectors 6 to ensure the stability of the carrier plate 3, making the carrier plate 3 more stable when rotating and avoiding shaking;

[0036] In use, firstly, the handwriting sample or evidence to be identified can be placed on the support plate 7. The sample is held by the staff, and the handwriting on the evidence is illuminated by the light source provided by the spotlight 4 for easy observation. Next, when it is necessary to adjust the angle of the handwriting sample, the staff can manually rotate the manual turntable 105. The manual turntable 105 drives the threaded rod 104 to rotate. Since the threaded rod 104 is connected to the rotating part 103 by a thread, the rotation of the threaded rod 104 will cause it to move up and down on the rotating part 103. The downward movement causes the third connecting piece 106 to move. Since one end of the third connecting piece 106 is rotatably connected to the fourth connecting piece 107, and the fourth connecting piece 107 is set on the carrier plate 3, the movement of the third connecting piece 106 will cause the carrier plate 3 to rotate around the axis between the second connecting piece 6 and the first connecting piece 5, thereby realizing the adjustment of the angle of the carrier plate 3. This design allows staff to easily adjust the observation angle of the handwriting sample as needed without frequently switching hand movements or adjusting body posture, which greatly improves the efficiency and accuracy of handwriting identification.

[0037] Example 2

[0038] Please see Figures 4-5 This utility model provides a technical solution:

[0039] Unlike Example 1;

[0040] The carrying plate 3 is also provided with a pair of guide holes 20, and a connecting rod 21 is slidably connected to each of the pair of guide holes 20. A fixing plate 23 is installed at one end of the connecting rod 21 by thread, and a clamping plate 22 is fixed at the other end of the connecting rod 21. A spring 24 is sleeved on the outer wall of the connecting rod 21. One end of the spring 24 abuts against the carrying plate 3, and the other end of the spring 24 abuts against the fixing plate 23. A handle 25 is provided on one side of the clamping plate 22.

[0041] The width of the clamping piece 22 is greater than the width of the guide hole 20 to prevent the clamping piece 22 from falling out of the guide hole 20;

[0042] The length of the connecting rod 21 is greater than the thickness of the carrier plate 3, so that the connecting rod 21 can extend out of the carrier plate 3;

[0043] When the sample is placed on the support plate 7, the two connecting rods 21 can be moved upwards to the top of the sample. At this time, the handle 25 is pulled upwards, and the handle 25 drives the connecting rods 21 to slide on the guide hole 20. At the same time, the spring 24 is compressed and the connecting rods 21 are moved downwards, so that the outer wall of the connecting rods 21 abuts against the top of the sample. Then the handle 25 is released, and the spring 24 returns to its original position, pushing the clamping piece 22 and the connecting rods 21 to move towards the sample, so that the clamping piece 22 tightly clamps the sample, thereby fixing the position of the sample. This design not only makes it easy for staff to quickly fix the sample, but also provides stable clamping, avoiding the sample from sliding or shifting when adjusting the observation angle, further improving the accuracy and efficiency of handwriting identification.
