Description

Technical Field

[0001] This invention belongs to the field of traffic safety equipment technology, specifically relating to an alcohol content detector with camera function for traffic safety. Background Technology

[0002] Traffic safety refers to the safe driving and walking of people on roads in accordance with traffic regulations to avoid personal injury or property damage. With the improvement of living standards, daily drinking has become common, leading to frequent cases of drunk driving. Personal injury or property damage caused by drunk driving is also commonplace. Therefore, in order to reduce personal injury or property damage caused by drunk driving, we have begun to conduct breathalyzer tests on drivers of vehicles passing through certain road sections. During these tests, traffic police typically use handheld breathalyzers to conduct the tests.

[0003] Existing technology CN213302243U discloses a breath alcohol content detector with good detection effect for traffic safety, including a support base. An alcohol content detection mechanism is fixedly connected to the midpoint of the top of the support base via a handle. The alcohol content detection mechanism includes a connecting plate, which is fixedly connected to the top of the handle. The alcohol detector body is fixedly installed on the right side of the top of the connecting plate. A ventilation tube communicating with the bottom left side of the alcohol detector body is fixedly connected to it. An electronic display screen is provided on the left side of the alcohol detector body and above the ventilation tube. The left side of the top of the connecting plate has symmetrical upright plates front and back, which are fixedly connected to each other by a fixed shaft. A rotating block is movably connected to the fixed shaft. A blowing cylinder is fixedly connected to the top of the rotating block via a connecting rod. The right end of the blowing cylinder is connected to the left end of the ventilation tube via a hose. A connecting seat is fixedly connected to the left end of the blowing cylinder. A blowing cover is provided on the left side of the connecting seat. Although the alcohol content detector has a video recording device to record the person being tested, its position cannot be changed. Therefore, after changing the position of the breathalyzer, the video recording device cannot guarantee that the person's face will be fully captured, and thus cannot ensure that cheating is recorded. This makes it inconvenient to use. In addition, it cannot provide a light source for the video recording device, so the video recording may be unclear in dark environments. Summary of the Invention

[0004] This invention provides a traffic safety alcohol content detector with a camera function. Its purpose is to solve the problems of alcohol content detectors that cannot be positioned to ensure that the face of the person being tested is fully captured, thus making it impossible to ensure that cheating is recorded. They are also inconvenient to use and cannot provide a light source for the recording agency, which may lead to unclear images in dark environments.

[0005] This invention provides a traffic safety alcohol content detector with camera function, comprising a connecting plate, an alcohol detector body mounted on the upper right side of the connecting plate, a ventilation pipe connected to the lower left side of the alcohol detector body, a flexible tube connected to the other end of the ventilation pipe, a blower connected to the other end of the flexible tube, a connecting rod fixed to the lower end of the blower, an electronic display screen one fixed to the upper left side of the alcohol detector body, a connecting module one installed between the lower end of the connecting rod and the connecting plate, an electronic display screen two fixed to the upper right side of the alcohol detector body, an upper connecting piece mounted above the alcohol detector body, the alcohol detector body and the upper connecting piece connected via the connecting module two, a mounting block fixed to the upper end of the upper connecting piece, and a camera and LED beads mounted on the left side of the mounting block.

[0006] Furthermore, the connecting module includes a rotating seat with the lower end of the connecting rod installed. The rotating seat and the connecting rod are connected by a friction hinge. A ring is fixed to the outer surface of the rotating seat. A rubber sheet is attached to the outer surface of the rotating seat at the lower end of the ring. Anti-slip textures are reserved on both sides of the rubber sheet. The lower end of the rotating seat is connected to the upper wall of the connecting plate. Both sides of the rubber sheet are in contact with the ring and the connecting plate.

[0007] Furthermore, the second connecting module includes a lower housing mounted on the top of the alcohol detector body, an upper housing mounted on the lower end of the upper connecting piece, and a constraint unit mounted between the lower housing and the upper housing. Multiple positioning units are mounted on the lower housing.

[0008] The upper and lower housings are adapted to each other. The upper housing can be rotatably clamped to the outside of the lower housing. The upper and lower housings are connected via a return unit, allowing the upper housing to move closer to or away from the lower housing.

[0009] The upper shell has multiple stop holes near the lower shell. The positioning unit and the stop holes correspond to and are adapted to each other. The positioning unit is located in the stop hole and is used to constrain the upper shell from rotating outside the lower shell.

[0010] The upper housing and the lower housing are connected by a constraint unit to constrain the upper housing from the outside of the lower housing;

[0011] When the upper housing is lifted upwards, the positioning unit can move upwards and move out of the stop port, releasing the constraint between the upper housing and the lower housing, allowing the upper housing to rotate outside the lower housing.

[0012] Furthermore, the constraint unit includes a connecting platform and a constraint strip. The upper housing also has a pre-reserved assembly opening. The circular piece at the lower end of the connecting platform is attached to the lower wall of the lower housing. The rod at the upper end of the connecting platform passes through the lower housing and is located in the assembly opening. The rod at the upper end of the connecting platform can move within the assembly opening. The constraint strip is installed on the rod of the connecting platform and can be attached to the lower wall of the assembly opening.

[0013] Furthermore, the constraint strip includes a tip and two side ends on the left and right sides of the tip. The rod at the upper end of the connecting platform has a second assembly opening. The tip of the constraint strip is connected to the side wall of the second assembly opening. The two side ends of the tip pass through the side of the second assembly opening and are located in the first assembly opening.

[0014] The constraint bar is a triangular spring steel bar with an open bottom.

[0015] Furthermore, a flange is installed on the inside of the first assembly port, and the movable part at the edge can fit and connect with the flange to constrain the rod of the connecting platform from moving out of the first assembly port.

[0016] Furthermore, the return unit is clamped to the outer surface of the rod body on the connecting platform, the lower end of the return unit is fixedly connected to the circular piece at the lower end of the connecting platform, and the upper end of the return unit is fixedly connected to the upper shell.

[0017] Furthermore, a plurality of positioning units and a plurality of stop ports are provided. The plurality of positioning units are distributed in a circular pattern at equal intervals on the lower housing, and the plurality of stop ports are distributed in a circular pattern at equal intervals on the upper housing. The positioning units and stop ports correspond to and are adapted to each other.

[0018] A guide unit is installed at one end of the upper housing near the lower housing, and a guide opening is reserved on the upper wall of the lower housing, with the guide unit located in the guide opening;

[0019] The positioning unit is a hemispherical protrusion protruding towards the upper shell, and the stop opening is a hemispherical opening.

[0020] Furthermore, the lower connecting piece and the upper connecting piece are connected by a friction hinge.

[0021] Furthermore, two pairs of LED beads are installed, and the two pairs of LED beads are evenly distributed around the camera.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. During use, the present invention allows the person being tested to directly adjust the position of the air blowing point by moving the air blower, making it very convenient to use. The dual electronic displays not only allow the person being tested to observe the testing situation intuitively, but also facilitate the inspector's observation without needing to flip the screen, greatly improving ease of use and accelerating testing efficiency. Furthermore, the camera's position can be adjusted to ensure accurate imaging of the person being tested. The improved LED lights provide a light source for imaging, ensuring clear camera shots and reducing limitations in use.

[0024] 2. This invention allows the vertical orientation of the air blowing point on the air blower to be adjusted by rotating the connecting rod on the rotating seat. At the same time, the horizontal position of the air blower can be adjusted by rotating the rotating seat on the connecting plate. This ensures that the person being tested can directly adjust the air blowing position by manually turning the lever, ensuring convenience during use. Furthermore, through the installation of the friction hinge and the rubber sheet, there is a certain friction between the connecting rod and the rotating seat, and between the rotating seat and the connecting plate, which ensures that the connecting rod and the rotating seat will not move without the action of external force.

[0025] 3. In this invention, the upper housing is screwed onto the outside of the lower housing, and the upper housing is connected to the lower housing via a return unit. The upper housing is provided with a stop port, and the lower housing is provided with a positioning unit. When the upper housing is lifted upward, the positioning unit can move upward and move out of the stop port, releasing the constraint between the upper housing and the lower housing, allowing the upper housing to rotate outside the lower housing, thereby achieving the purpose of changing the position of the camera. At the same time, after the position of the camera is changed, simply releasing the upper housing will allow the upper housing and the lower housing to be stably and securely fixed, thus stopping the upper housing and the lower housing to prevent the camera from moving during use and ensuring clear imaging of the inspected personnel.

[0026] 4. The present invention, through the installation of the connecting platform and the constraint strip, not only ensures that the upper shell can move close to or away from the lower shell, but also prevents the upper shell from moving out of the lower shell. Furthermore, the constraint strip is made of triangular spring steel strip, which can change shape under its own deformation, allowing the rod on the connecting platform to connect with the upper shell more easily. Moreover, the constraint strip can be opened after it extends into the assembly port, thereby preventing the connecting platform from moving away from the upper shell.

[0027] 5. The present invention uses a positioning unit and a stop port. The positioning unit adopts a hemispherical protrusion and the stop port is a hemispherical opening. When the upper shell moves upward and rotates, the hemispherical protrusion can collide with the hemispherical opening to produce a sound, thereby improving the user experience of the testing personnel.

[0028] 6. The present invention, through the installation of a guide unit and a guide port, allows the guide unit to assist the upper housing in rotating outside the lower housing, thereby making the upper housing rotate more smoothly.

[0029] 7. The present invention allows for adjustment of the vertical orientation of the camera by moving the upper connecting piece, so as to adjust the vertical orientation of the camera. At the same time, the camera can remain stationary when the upper connecting piece is not subjected to external force.

[0030] 8. This invention provides a balanced light source for the camera's shooting by using LED beads, ensuring the clarity of the shooting.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] Reference Figure 1-10 This invention provides a traffic safety alcohol content detector with camera function, comprising a connecting plate 1, an alcohol detector body 2 mounted on the upper right side of the connecting plate 1, a ventilation pipe 15 connected to the lower left side of the alcohol detector body 2, a flexible hose 3 connected to the other end of the ventilation pipe 15, a blower 4 connected to the other end of the flexible hose 3, a connecting rod 5 fixedly connected to the lower end of the blower 4, an electronic display screen 6 fixedly connected to the upper left side of the alcohol detector body 2, the electronic display screen 6 being electrically connected to the alcohol detector body 2, and a connecting mold installed between the lower end of the connecting rod 5 and the connecting plate 1. Block 7, the upper right side of the alcohol detector body 2 is fixedly connected to the electronic display screen 2 8, the electronic display screen 2 8 is electrically connected to the alcohol detector body 2, the upper connecting piece 10 is installed above the alcohol detector body 2, the alcohol detector body 2 and the upper connecting piece 10 are connected by the connecting module 2 9, the upper end of the upper connecting piece 10 is fixedly connected to the mounting block 11, the left side of the mounting block 11 is equipped with the camera 12 and the LED light bead 13, the LED light bead 13 is electrically connected to the alcohol detector body 2, and the camera 12 is electrically connected to the electronic display screen 6 and the electronic display screen 2 8.

[0046] During use, the person being tested can directly adjust the position of the air blowing point by moving the air blower 4, making it very convenient to use. At the same time, the dual electronic display screens not only allow the person being tested to observe the test situation intuitively, but also make it easy for the inspector to observe the test situation intuitively without having to flip it over to check, which greatly improves the convenience of use and speeds up the test efficiency. In addition, the position of the camera 12 can be adjusted so that the camera 12 can accurately capture the person being tested. At the same time, the LED beads 13 can provide a light source for the shooting, ensuring that the camera 12 captures clear images and reducing the limitations of use.

[0047] Reference Figure 1 and Figure 2 The connecting module 7 includes a rotating seat 71 at the lower end of the connecting rod 5. The rotating seat 71 and the connecting rod 5 are connected by a friction hinge 73. A ring 72 is fixed to the outer surface of the rotating seat 71. A rubber sheet 74 is clamped to the outer surface of the rotating seat 71 at the lower end of the ring 72. Anti-slip textures are reserved on both sides of the rubber sheet 74. The lower end of the rotating seat 71 is connected to the upper wall of the connecting plate 1. Both sides of the rubber sheet 74 are in contact with the ring 72 and the connecting plate 1.

[0048] By rotating the connecting rod 5 on the rotating seat 71, the vertical position of the air blowing point on the air blower 4 can be adjusted. At the same time, by rotating the rotating seat 71 on the connecting plate 1, the horizontal position of the air blower 4 can be adjusted, ensuring that the person being tested can directly adjust the air blowing position by manually turning it, ensuring convenience during use. Furthermore, through the installation of the friction hinge 73 and the rubber sheet 74, there is a certain friction between the connecting rod 5 and the rotating seat 71, and between the rotating seat 71 and the connecting plate 1, which ensures that the connecting rod 5 and the rotating seat 71 will not move without the action of external force.

[0049] Reference Figure 4-8The connecting module 2 9 includes a lower housing 91 mounted on the top of the alcohol detector body 2, an upper housing 92 mounted on the lower end of the upper connecting piece 10, and a constraint unit 94 mounted between the lower housing 91 and the upper housing 92. The upper housing 92 and the lower housing 91 are adapted to each other. The upper housing 92 can be rotatably clamped to the outside of the lower housing 91. The upper housing 92 and the lower housing 91 are connected via a return unit 93, allowing the upper housing 92 to move towards or away from the lower housing 91. Multiple positioning units 911 are fixedly connected to the end of the lower housing 91 that approaches the upper housing 92. Multiple stop ports 921 are reserved at one end. The positioning unit 911 and the stop ports 921 correspond to and are adapted to each other. The positioning unit 911 is located in the stop port 921 and is used to constrain the upper housing 92 to rotate outside the lower housing 91. The upper housing 92 and the lower housing 91 are connected by a constraint unit 94, which is used to constrain the upper housing 92 to move away from the outside of the lower housing 91. When the upper housing 92 is lifted upward, the positioning unit 911 can move upward and move out of the stop port 921, releasing the constraint between the upper housing 92 and the lower housing 91, allowing the upper housing 92 to rotate outside the lower housing 91.

[0050] Reference Figure 6 and Figure 7 After the upper housing 92 is rotated and clamped onto the outside of the lower housing 91, to prevent the upper housing 92 and the lower housing 91 from separating from each other, the constraint unit 94 includes a connecting platform 941 and a constraint strip 942. An assembly opening 922 is also provided on the upper housing 92, located axially at the center of the upper housing 92. The circular piece at the lower end of the connecting platform 941 is fitted and connected to the lower wall surface of the lower housing 91. A circular opening is provided on the lower wall surface of the lower housing 91, allowing the circular piece at the lower end of the connecting platform 941 to move within the circular opening. When the circular piece at the lower end of the connecting platform 941 moves upward to a designated position, the circular opening... The upper wall surface can fit against the circular piece at the lower end of the connecting platform 941 to constrain the connecting platform 941 to move upwards; the rod at the upper end of the connecting platform 941 passes through the lower housing 91 and is located in the assembly port 922. The lower housing 91 is clamped to the outside of the connecting platform 941, allowing the connecting platform 941 to rotate on the lower housing 91 with the vertical center line of the connecting platform 941 as the rotation center, and the rod at the upper end of the connecting platform 941 can move in the assembly port 922. The constraint strip 942 is installed on the rod of the connecting platform 941, and the constraint strip 942 can fit and connect with the lower wall surface of the assembly port 922.

[0051] Reference Figure 6-8The constraint bar 942 includes a tip 9421 and two side ends 9422 on the left and right sides of the tip 9421. A mounting opening 9411 is pre-drilled on the upper part of the rod of the connecting platform 941. The constraint bar 942 is located within the mounting opening 9411. The tip 9421 of the constraint bar 942 is connected to the side wall of the mounting opening 9411. The tip 9421 of the constraint bar 942 is fixed to the side wall of the mounting opening 9411 via a shaft 95. The two sides of the tip 9421 are connected, and the edges 9422 on both sides penetrate the side of the second assembly port 9411 and are located in the first assembly port 922. The opening of the first assembly port 922 faces the inside of the first assembly port 922 and a flange 94111 is installed. The movable part of the edge 9422 can fit and connect with the flange 94111. The rod used to constrain the connecting platform 941 is moved out of the first assembly port 922. The constraint bar 942 is a triangular spring steel bar with an open bottom.

[0052] When in use, lift the upper housing 92 upwards, and the constraint bar 942 in the assembly port 922 opens to the left and right. The positioning unit 911 on the lower housing 91 can move toward or away from the stop port 921, creating a gap between the stop port 921 and the positioning unit 911. Then rotate the upper housing 92. At this time, the connecting platform 941 and the upper housing 92 rotate together. When the camera 12 on the upper housing 92 moves to be able to completely capture the detection, release the upper housing 92. At this time, the upper housing 92 will no longer have an upward lifting force. With the cooperation of the return unit 93, the upper housing 92 moves toward the lower housing 91. The constraint bar 942 returns to its original shape with the cooperation of its own deformation force. At this time, the positioning unit 911 can be in the stop port 921, and then the upper housing 92 and the camera 12 above it are stopped.

[0053] The return unit 93 is clamped to the outer surface of the rod body on the connecting platform 941. The lower end of the return unit 93 is fixed to the circular piece at the lower end of the connecting platform 941, and the upper end of the return unit 93 is fixed to the upper housing 92. This allows the return unit 93 and the connecting platform 941 to form a whole, connecting the upper housing 92 and the lower housing 91. This not only ensures that the upper housing 92 can be connected to the connecting platform 941 and the lower housing 91 via the return unit 93, but also ensures that the upper housing 92 can return to its original position after being released during use. Furthermore, it ensures that when the upper housing 92 is rotated, the return unit 93 can pull the connecting platform 941 to rotate together. The return unit 93 uses a spiral beryllium copper wire.

[0054] Reference Figure 9 and Figure 10Several positioning units 911 and several stop ports 921 are installed. Several positioning units 911 are distributed in a circular pattern at equal intervals on the lower housing 91, and several stop ports 921 are distributed in a circular pattern at equal intervals on the upper housing 92. The positioning units 911 and the stop ports 921 correspond to and are adapted to each other. The positioning unit 911 is a hemispherical protrusion protruding towards the upper housing 92, and the stop port 921 is a hemispherical opening.

[0055] A guide unit 923 is installed at one end of the upper housing 92 near the lower housing 91. A guide opening 912 is reserved on the upper wall of the lower housing 91. The guide unit 923 is located in the guide opening 912. The guide unit 923 is made of steel ball. The guide opening 912 is circular. There are two pairs of guide units 923. The two pairs of guide units 923 are evenly distributed on the edge of the lower housing 91. The guide opening 912 is located on the edge of the lower housing 91.

[0056] In order to connect the upper housing 92 and the upper connecting piece 10, the lower connecting piece 96 for connection is fixedly connected to the upper wall surface of the upper housing 92.

[0057] Reference Figure 1 The upper end of the upper housing 92 is fixedly connected to the lower connecting piece 96, and the lower connecting piece 96 and the upper connecting piece 10 are screwed together by a friction hinge 14.

[0058] The vertical orientation of the camera 12 can be adjusted by moving the upper connecting piece 10, so that the vertical orientation of the camera 12 can be adjusted. At the same time, the camera 12 can remain stationary when the upper connecting piece 10 is not subjected to external force.

[0059] Reference Figure 3 Two pairs of LED beads 13 are installed, and the two pairs of LED beads 13 are evenly distributed around the camera 12.

[0060] The LED beads 13 provide a balanced light source for the camera 12 to capture images, ensuring image clarity.

[0061] The specific implementation method is as follows: In use, the testing personnel take the device to the person being tested. The person being tested directly pulls the air blower 4 to adjust the position of the air blowing point so that the air blowing point is at the person's mouth. At the same time, the testing personnel adjust the position of the camera 12 so that the camera 12 can completely capture the face of the person being tested. Lift the upper housing 92 upwards, and the constraint strip 942 in the assembly port 922 opens to the left and right. The positioning unit 911 on the lower housing 91 can move toward or away from the position of the stop port 921, so that a gap appears between the stop port 921 and the positioning unit 911. Then rotate the upper housing 92. At this time, the connecting table 941 and the upper housing 92 rotate together. When the upper housing 92... When the camera 12 is adjusted to be able to fully capture the image of the person being tested, the upper housing 92 is released. At this moment, the upper housing 92 will no longer have any upward lifting force. With the cooperation of the return unit 93, the upper housing 92 moves towards the lower housing 91. The constraint bar 942 returns to its original shape with the cooperation of its own deformation force. At this moment, the positioning unit 911 can be in the stop port 921. Then, the upper housing 92 and the camera 12 above it are stopped. Then, the testing personnel are notified to start the person being tested to blow into the air. The alcohol tester body 2 displays the detected data and captured images on the electronic display screen 1 6 and the electronic display screen 2 8. The testing personnel and the person being tested can observe the data and images on the electronic display screen.
