Description
Technical Field
[0001] The utility model belongs to the field of traffic accident determination tools, and particularly relates to a visible tire mark feature extraction device. Background Art
[0002] Visible tire marks are an important type of evidence commonly seen in traffic accidents. They usually reflect information such as the vehicle's motion state, tire specifications, and usage conditions. When extracting tire marks, collection sheets, cameras, measuring tools, and software processing tools are often used. When staff members extract tire marks, they often encounter situations where the light is dim or even at night, and the extracted images are unclear. Moreover, when taking evidence photos, measuring tools are needed to measure and photograph key data such as the length, width, and depth of the tire marks. Currently used measuring tools are mostly tape measures or straight rulers. When taking photos, multiple people need to cooperate. One person squats down to align the measuring tool with the tire mark, and another person takes the photo. Especially in dim conditions, an additional person is needed for lighting, which is rather inconvenient. After sampling, the staff needs to clean the tire marks to avoid traffic accidents caused by the reduction of the road friction coefficient due to the tire marks. However, when cleaning the tire marks, additional tools need to be carried, which is extremely inconvenient. Therefore, a visible tire mark feature extraction device is needed. Content of the Utility Model
[0003] The purpose of the utility model is to provide a visible tire mark feature extraction device that does not require multiple people to cooperate in taking evidence photos of tire marks and can clean the tire marks.
[0004] The visible tire mark feature extraction device includes a vertically arranged grip rod. A storage cover with a downward-facing cover opening is fixed at the bottom of the grip rod. A partition that divides the space into left and right compartments is vertically fixed inside the storage cover. Two movable rods that can move up and down pass vertically through the top of the storage cover. A locking component for locking the movable rods after movement is arranged between the two movable rods and the grip rod. The lower ends of the two movable rods are respectively located in the left and right compartments. A straight ruler is hinged to the bottom of one of the movable rods. A positioning component for positioning the swung straight ruler is arranged at the hinge of the straight ruler and the movable rod. A cleaning component for cleaning the tire marks is arranged on the other movable rod. A plurality of lighting components are arranged on the storage cover. A support component for supporting the storage cover in a vertical state is arranged on the storage cover.
[0005] Furthermore, the cleaning component includes a brush. The lower end of the other movable rod is fixed with an installation box. A motor is installed inside the installation box. The output end of the motor passes through the bottom of the installation box. The brush is installed on the output end of the motor.
[0006] Further, the positioning component includes a positioning post, which is horizontally fixed on the straight ruler. The axis of the hinge point between the positioning post and the straight ruler and the moving rod is aligned. An installation groove is formed at the bottom of the moving rod, and a top block that fits against the outer cylindrical surface of the positioning post is independently inserted into the installation groove. A reset member for resetting the moved top block is provided between the top block and the bottom of the groove.
[0007] Further, anti-slip patterns for increasing the friction force are provided on both the bottom of the top block and the outer cylindrical surface of the positioning post.
[0008] Further, the support component includes two support rods. A moving sleeve is independently sleeved on the storage cover, and a screw is inserted through the moving sleeve. One ends of the two support rods are symmetrically hinged on the moving sleeve, and a cross bar for fitting against the ground is fixed between the other ends of the two support rods.
[0009] Further, the locking component includes two moving blocks, which are respectively fixed on the tops of the two moving rods.

Specific embodiments
[0021] The present utility model will be further described below through specific embodiments with reference to the accompanying drawings, but it is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present invention. Embodiment
[0022] A visual tire mark feature extraction device described in this embodiment, as Figure 1 、 Figure 4 and Figure 6 shown, includes a vertically arranged grip rod 1. A storage cover 6 with a downward-facing opening is fixed at the bottom of the grip rod 1. A partition board 12 that vertically divides the space into left and right chambers is fixedly arranged inside the storage cover 6. The cross-section of the storage cover 6 is of a rectangular structure. Of course, a circular structure can also be adopted. The partition board 12 is vertically located inside the storage cover 6, thereby dividing the internal space of the storage cover 6 into a left chamber and a right chamber, which are respectively used for storing a straightedge 13 and a brush 11;
[0023] A rod sleeve 2 that prevents slipping between the palm and the grip rod 1 is sleeved on the grip rod 1. The rod sleeve 2 is made of elastic materials such as rubber, silica gel, and latex, which can effectively increase the friction between the staff's palm and the rod body of the grip rod 1, avoid the situation of hand slipping during use, and the rod sleeve 2 can also improve the comfort of the palm;
[0024] Two movable moving rods 5 penetrate vertically through the top of the storage cover 6. Two through holes for the moving rods 5 to penetrate are opened at the top of the storage cover 6. The two through holes communicate with the left and right chambers respectively. The moving rods 5 are in contact with the rod body of the grip rod 1 and move up and down;
[0025] Further description is as follows. As Figure 1 , Figure 5 and Figure 6 shown, preferably, this embodiment includes two moving blocks 3, which are respectively fixed to the tops of two moving rods 5. The side walls of the two moving blocks 3 facing the grip rod 1 are arc-shaped and fit on the grip rod 1. The diameters of the arc-shaped side walls of the two moving blocks 3 are the same as the diameter of the grip rod 1. After the two moving blocks 3 are fitted with the grip rod 1, the two moving rods 5 can be positioned to prevent the two moving rods 5 from moving back and forth. Screws for locking the moved moving blocks 3 are inserted through all the moving blocks 3. Threaded holes in threaded cooperation with the screws are formed in the side walls of all the moving blocks 3. The threaded ends of the screws are inserted into the threaded holes and abutted against the surface of the grip rod 1, so as to lock the moved moving rods 5. Pull handles 4 are fixed to all the moving blocks 3. When in use, the staff can push the moving blocks 3 by pulling the pull handles 4 on the two moving blocks 3, so that the moving blocks 3 drive the corresponding moving rods 5 to move. During use, the staff member pulls the pull handle 4 to make the moving block 3 drive the corresponding moving rod 5 to move along the length direction of the grip rod 1. When the moving rod 5 moves to a suitable position, the screw is rotated so that the threaded end of the screw abuts against the surface of the grip rod 1, thereby locking the moved moving rod 5. This solution as a whole constitutes a locking assembly for locking the moved moving rod 5. Of course, the locking assembly can also adopt a positioning pin. A plurality of positioning holes for inserting the positioning pin are formed along the rod body of the grip rod 1. Through holes for the positioning pin to pass through are formed in all the moving blocks 3. When the moving block 3 moves to a suitable position, the through hole and the positioning hole aligned at this position are aligned, and one end of the positioning pin is inserted through the through hole and the positioning hole, thereby locking the moved moving rod 5.
[0026] The lower ends of the two moving rods 5 are respectively located in the left and right cabins. When the two moving rods 5 move up and down, they will drive the components connected to them to pass out from the cover opening at the lower end of the storage cover 6, so as to be used. The storage cover 6 can protect the components stored inside from being damaged.
[0027] The bottom of one of the moving rods 5 is hinged with a straight ruler 13. The straight ruler 13 and the bottom of the moving rod 5 are hinged through a pivot. Hinge seats are fixed on both the straight ruler 13 and the bottom of the moving rod 5. During installation, first, a through hole for the independent penetration of the pivot is opened in one of the hinge seats, and the pivot is fixed on the other hinge seat, so that the straight ruler 13 can swing freely. When the straight ruler 13 swings to be parallel to the moving rod 5, the straight ruler 13 can be stored in the left compartment of the storage cover 6. Of course, the straight ruler 13 and the bottom of the moving rod 5 can also be hinged through a bearing. Generally, the structure of a bearing has an inner ring and an outer ring. When realizing the hinge, the straight ruler 13 can be fixed to the outer ring, and the moving rod 5 can be fixed to the inner ring, so as to realize the hinge between the straight ruler 13 and the moving rod 5;
[0028] An anti-slip pad for preventing slipping is fixed on the side wall of the straight ruler 13 in contact with the ground. The anti-slip pad is made of materials such as rubber, silica gel, and latex. When the straight ruler 13 is attached to the ground, the anti-slip pad can effectively increase the friction between the straight ruler 13 and the ground, preventing the straight ruler 13 from slipping during use;
[0029] Further explanation is as follows Figure 1 、 Figure 2 and Figure 4 As shown, preferably, a positioning post 17 is included in this embodiment. The positioning post 17 is horizontally fixed on the straight ruler 13. The axis of the positioning post 17 is aligned with the axis of the hinge point between the straight ruler 13 and the moving rod 5. An installation groove is opened at the bottom of the moving rod 5. A top block 16 that fits the outer cylindrical surface of the positioning post 17 is independently inserted into the installation groove. A reset member 15 for resetting the moved top block 16 is arranged between the top block 16 and the groove bottom. In this embodiment, the reset member 15 is a compression spring. Of course, the reset member 15 can also be a spring piece. During use, the reset member 15 pushes the top block 16 to press against the outer cylindrical surface of the positioning post 17. When the straight ruler 13 adjusts the angle, the positioning post 17 rotates around the hinge point as the center. Anti-slip patterns for increasing friction are provided on both the bottom of the top block 16 and the outer cylindrical surface of the positioning post 17. When the straight ruler 13 swings to a suitable position, the top block 16 can play a partial positioning effect on the straight ruler 13 through the friction with the positioning post 17, preventing the straight ruler 13 from swinging easily. This solution as a whole constitutes a positioning component for positioning the swung straight ruler 13. Of course, the positioning component can also use bolts and nuts. The pivot at the hinge between the moving rod 5 and the straight ruler 13 is replaced with a bolt, and the nut is sleeved on the bolt. By rotating the bolt or the nut, the tightness of the fit between the two hinge seats is adjusted, so as to play a partial positioning effect on the straight ruler 13 after swinging through the friction between the two hinge seats.
[0030] Further explanation is as follows Figure 1 、 Figure 5 and Figure 6As shown in the figure, preferably, this embodiment includes a brush 11. The lower end of another moving rod 5 is fixed with a mounting box 9. A motor 10 is installed in the mounting box 9. The output end of the motor 10 passes through the bottom of the mounting box 9, and the brush 11 is installed on the output end of the motor 10. When in use, when the moving rod 5 moves downward, it will drive the mounting box 9 and the brush 11 fixed at the bottom to pass downward through the port at the bottom of the storage cover 6. The motor 10 drives the brush 11 to rotate, and the high-speed rotating brush 11 is used to clean the tire marks on the ground, avoiding traffic accidents caused by the reduction of the ground friction coefficient by the tire marks without the need to carry additional cleaning tools. In this embodiment, the bristles on the brush 11 are made of metal materials such as steel wire, iron wire or stainless steel wire. When the brush 11 enters the right chamber of the storage cover 6, the chamber wall will straighten and arrange the bristles on the brush 11 to prevent the bristles from bending and fluffing after multiple uses and affecting subsequent use. This solution as a whole constitutes a cleaning component for cleaning tire marks. Of course, the cleaning component can also use a vibration motor. The vibration motor is installed on the moving rod 5, and the brush 11 is fixed at the bottom of the moving rod 5. The vibration motor drives the brush 11 to vibrate, thereby cleaning the road surface.
[0031] A number of lighting components are provided on the storage cover 6. In this embodiment, the lighting component used is a lighting lamp with a gooseneck tube 7. The gooseneck tube is also called a snake tube, a metal shaping hose, a metal part that can be bent arbitrarily and determine the direction, and is often used in lighting table lamps, medical applications, etc. When in use, only by twisting the direction of the gooseneck tube 7 can the lighting direction of the lighting lamp be changed. Of course, the lighting component can also use a miner's lamp. The miner's lamp is installed on the storage cover 6, and the ground can be illuminated by the miner's lamp. The storage cover 6 is installed with a mounting ring 18 through the gooseneck tube 7. When in use, a photographic device can be installed in the mounting ring 18 to take fixed-point photos of the tire marks on the ground.
[0032] Further explanation is as follows Figure 1 、 Figure 4 and Figure 6As shown, preferably, this embodiment includes two support rods 14. A movable sleeve 19 is independently sleeved on the storage cover 6. A screw is inserted through the movable sleeve 19. One ends of the two support rods 14 are symmetrically hinged on the movable sleeve 19. A cross bar for fitting with the ground is fixed between the other ends of the two support rods 14. A threaded hole in threaded cooperation with the screw is formed in the movable sleeve 19. One end of the screw abuts against the surface of the storage cover 6, so as to lock the moved movable sleeve 19. One ends of the two support rods 14 are hinged on the left and right side walls of the storage cover 6 through pivot shafts. During installation, a through hole for independently inserting the pivot shaft is formed in one ends of the two support rods 14. The pivot shaft is fixed on the left and right side walls of the storage cover 6, so that the two support rods 14 can swing at different angles. After being connected by the cross bar, the two support rods 14 can swing synchronously. The cross bar is fitted on the ground to increase the friction force. By supporting the storage cover 6 with the two support rods 14, this feature extraction device can be vertically placed on the ground, without the need for multiple people to cooperate, and without the need for staff to hold it by hand, enabling the staff to free their hands for evidence-taking photography. This solution as a whole constitutes a support assembly for supporting the storage cover 6 in a vertical state. Of course, the support assembly can also adopt a support plate. A slidable slider is installed on the storage cover 6 through a slide rail. One end of the support plate is hinged on the slider, and the other end supports on the ground, so as to support the storage cover 6.
[0033] During actual use, when taking evidence by photographing, first pull the handle 4 on the left moving block 3 to push the moving block 3 to move downward along the rod body of the grip rod 1, so that the left moving rod 5 drives the straight ruler 13 to pass through the cover opening of the storage cover 6. When the straight ruler 13 moves to a suitable position, lock the moved moving rod 5 by rotating the screw on the moving block 3. Then swing the straight ruler 13 to the horizontal state. The top block 16 is tightly attached to the positioning column 17 under the extrusion of the reset member 15, and the straight ruler 13 can be partially positioned through the frictional force, so that the straight ruler 13 maintains the horizontal state and will not swing easily. Then place the straight ruler 13 beside the tire mark, turn on all the lighting parts to illuminate the tire mark. When the straight ruler 13 is aligned with the tire mark, move the sleeve 19 downward to a suitable position and lock it with a screw. Then swing the two support rods 14 so that the cross bars on the swinging ends of the two support rods 14 are attached to the ground, and the support rods 14, the storage cover 6 and the ground form a triangular structure, so that the feature extraction device can be vertically placed beside the tire mark without the need for multiple people to cooperate and without the need for the staff to hold it by hand. The straight ruler 13 can measure the tire mark, and the staff can then free their hands to take evidence by photographing. After taking evidence by photographing, pull the handle 4 on the right moving block 3 to push the moving block 3 to move downward along the rod body of the grip rod 1, so that the right moving rod 5 drives the brush 11 to pass through the cover opening of the storage cover 6. When the brush 11 moves to a suitable position, lock the moved moving rod 5 by rotating the screw on the moving block 3. Then start the motor 10 to drive the brush 11 to rotate, and use the high-speed rotating brush 11 to clean the tire mark on the ground, avoiding traffic accidents caused by the reduction of the friction coefficient of the ground by the tire mark without the need to carry additional cleaning tools.
