Technical Field

[0001] The utility model relates to the technical field of traffic sign plate detection equipment, in particular to a traffic sign plate appearance detection device. Background Art

[0002] Traffic signs are facilities used for traffic management that use graphic symbols, colors and text to convey specific information to traffic participants. Their shape, pattern, size, setting, construction, reflection, lighting, color range of road traffic signs and production must all be carried out in accordance with regulations. Traffic signs need to be tested for their dimensions before they are put into use, so a special traffic sign shape detection device is needed.

[0003] At present, the most widely used detection method is to use a steel tape measure for measurement. When encountering a larger-sized sign board, it is difficult to fix the end of the steel tape measure, which brings inconvenience to the measurement of the sign board size. At the same time, when using a steel tape measure for measurement, it is easy to cause errors in the measurement results due to the skew of the steel tape measure, thereby reducing the accuracy of the detection result. For this reason, we provide a traffic sign board appearance detection device. Utility Model Content

[0028] Testing station 1;

[0029] The detection component includes a limit plate 101 symmetrically arranged on the top of the detection platform 1, and the bottoms of the two groups of limit plates 101 are respectively fixedly connected to a connecting frame 102 and a connecting frame 2 103, a tooth plate 104 is fixedly connected to the connecting frame 102, and a tooth plate 2 105 is fixedly connected to the connecting frame 2 103. The top of the detection platform 1 is symmetrically provided with a strip groove 2, and the inner side of the strip groove 2 is symmetrically provided with a guide groove, and the connecting frame 102 and the connecting frame 2 103 are symmetrically fixedly connected with a guide block 3, and the guide block 3 and the guide groove The two sets of limit plates 101 are slidably connected to each other, and can guide the horizontal movement of the two sets of limit plates 101. A pointer 4 is fixedly installed on one side of the two sets of limit plates 101. A horizontal plate 5 is fixedly installed on the top of the testing platform 1. A scale 6 is arranged on the surface of the horizontal plate 5. The center position of the scale 6 is the zero scale line. From the zero scale line, the value of the scale 6 gradually increases toward both sides. The horizontal plate 5 can ensure that the traffic sign is placed horizontally. By using the pointer 4 in conjunction with the scale 6, the size of the traffic sign can be quickly measured.

[0030] Gear 106, gear 106 is rotatably connected to the bottom center of the test bench 1 and is meshed with tooth plate 1 104 and tooth plate 2 105 at the same time, and a hand wheel 107 is coaxially fixedly connected to one side of the gear 106;

[0031] The anti-deformation component includes a top plate 201 , a connecting rod 202 is hinged between the top plate 201 and the limiting plate 101 through a hinge, and a pressing plate 203 is horizontally arranged below the top plate 201 .

[0032] The anti-deformation components also include:

[0033] The vertical rods 204 are four in number and are symmetrically fixedly connected to the top of the pressure plate 203. The vertical rods 204 pass through the top plate 201 and are slidably connected to the top plate 201. The outer sleeve of the vertical rods 204 is provided with a spring 205. The two ends of the spring 205 are respectively fixedly connected to the top plate 201 and the pressure plate 203. The top of the vertical rods 204 is fixedly connected with an anti-detachment plate 206, which can prevent the vertical rods 204 from detaching from the top plate 201.

[0034] The implementation principle of a traffic sign plate appearance detection device in the embodiment of the present application is as follows: first, the traffic sign plate is placed on the detection platform 1 and one side of the traffic sign plate is pressed against the horizontal plate 5 to keep the placement position horizontal, and then the hand wheel 107 is rotated to drive the gear 106 to rotate, so that the tooth plate 104 and the tooth plate 2 105 can be driven to move toward each other at the same time, thereby driving the two sets of limit plates 101 to move toward each other at the same time, and during the movement of the limit plates 101, the traffic sign plate can be continuously pushed to the center position until it is clamped and fixed. At this time, the size of the traffic sign plate can be obtained by adding the values ​​of the scales 6 pointed to by the two sets of pointers 4. At the same time, in the process of clamping and measuring the traffic sign plate, the top plate 201 and the hinged effect of the limit plate 101 and the connecting rod 202 are utilized to push the pressure plate 203 to move vertically downward, so that the traffic sign plate can be pressed down from the top to prevent its two sides from arching and deforming when under pressure. When the pressure plate 203 first contacts the traffic sign plate, the sliding cooperation between the top plate 201 and the vertical rod 204 is utilized to make the top plate 201 continuously compress the spring 205, thereby playing a certain buffering role until the limit plate 101 completes the clamping and fixing of the traffic sign plate, and finally the hand wheel 107 is reversed to remove the traffic sign plate. Example

[0035] The present embodiment is further improved on the basis of the embodiment 1 in that the facing surfaces of the two sets of limiting plates 101 are both designed to be rough surfaces, which can play an anti-slip role.
