Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, and particularly relates to a fixing device for a vehicle-mounted dynamic marking measuring instrument. Background Technique

[0002] A vehicle-mounted marking measuring instrument is an instrument used to measure the retroreflective coefficient of road markings (that is, the reflected brightness of road markings after being irradiated by the headlight at night or under low light conditions). This instrument is usually mounted on a vehicle and can dynamically measure the reflection performance of road markings during vehicle driving, so as to evaluate the visibility and safety of the markings.

[0003] In the prior art, a vehicle-mounted marking retroreflective measuring instrument with the publication number of "CN114103818A" includes a measuring instrument body, a mounting frame, an adjustment groove, a motor, a lead screw, an adjustment block and a connecting rod. The adjustment groove is rotatably connected to the mounting frame and is located at one end of the mounting frame. The two ends of the lead screw are respectively rotatably connected to the adjustment groove and are located inside the adjustment groove. The adjustment block is threadedly connected to the lead screw and sleeved on the outer wall of the lead screw, and both sides of the adjustment block are respectively slidably connected to the adjustment groove. The motor is arranged inside the adjustment groove, and the output end of the motor penetrates through the adjustment groove and is fixedly connected to the lead screw. One end of the connecting rod is fixedly connected to the adjustment block and is located on one side of the adjustment block. The measuring instrument body is fixedly connected to the connecting rod and is located at the end of the connecting rod away from the adjustment block. The above structural settings can be used for measurement by being carried by an automobile, reducing the occurrence of safety accidents and ensuring the safety of measurement personnel at the same time.

[0004] However, there are still relatively large deficiencies in the prior art, such as:

[0005] This device only uses a connecting rod to connect and fix the vehicle-mounted marking measuring instrument. During the actual measurement process, it will cause the vehicle-mounted marking measuring instrument to generate relatively large vibrations during actual work, making the measurement results of the vehicle-mounted marking measuring instrument inaccurate. Content of the Utility Model

[0006] The purpose of the utility model is to provide a fixing device for a vehicle-mounted dynamic marking measuring instrument to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Please refer to Figure 1-6 , the present invention provides a technical solution:

[0032] Embodiment 1:

[0033] A fixing device for a vehicle-mounted marking measuring instrument 3, which is mainly composed of a connecting plate 2, a vehicle-mounted marking measuring instrument 3 and a series of precise connection and fixing components, aiming to realize the stable fixing and efficient operation of the measuring instrument during vehicle driving, as well as the efficient installation of the vehicle-mounted marking measuring instrument 3.

[0034] The device is first firmly adsorbed on the side wall of the vehicle body 1 through the main suction cup 4. A suction cup rod 5 is further fixed on the main suction cup 4 as the basis of the support structure. The top of the suction cup rod 5 is provided with a rod connecting device 6, which not only undertakes the connection function but also has the functions of angle adjustment and locking. The main pull rod 7 is fixed on the rod connecting device 6 to form the main support frame.

[0035] To further improve the stability of the device, a number of auxiliary suction cups 12 are also installed on the vehicle body 1, and they are also connected to the rod connecting device 6 through the suction cup rod 5. The auxiliary vertical rods 11 are distributed at the four corners of the top of the connecting plate 2 and are fixedly connected to the rod connecting device 6, and are connected to the rod connecting device 6 on the auxiliary suction cup 12 through the auxiliary pull rod 13. This multi-point fixing design effectively disperses the vibration and impact force during the operation of the measuring instrument, ensuring the accuracy and stability of the measurement.

[0036] The vehicle-mounted marking measuring instrument 3, as the core component, is designed with an I-shaped slide rail 8 at its top, which is convenient for matching with the slideway 9 on the connecting plate 2 to achieve sliding installation. The connecting plate 2 not only bears the weight of the measuring instrument but also forms a stable support system with the main vertical rod 10 and several auxiliary vertical rods 11 arranged on it, the main pull rod 7 and the rod connecting device 6. The main vertical rod 10 is also connected to the rod connecting device 6 to ensure a firm connection with the main pull rod 7 and enhance the stability of the overall structure.

[0037] The main body of the rod connecting device 6 is a main rod sleeve 61, on the side wall of which a secondary rod disc 62 is fixed, and a threaded cylinder 63 is fixedly connected to the secondary rod disc 62. The first rod clamp 64 and the second rod clamp can rotate freely around the threaded cylinder 63 to meet the connection requirements of rods at different angles. The groove 641 opened on the rod clamp is convenient for the positioning and fixing of the rod. By tightening the first locking bolt 642, the pressing block 643 tightly presses the rod clamp against the rod to achieve preliminary locking. The threaded hole 65 on the side wall of the main rod sleeve 61 is used to install the second locking bolt 66 to further lock the rod in the main rod sleeve 61 and ensure the stability of the connection.

[0038] During the actual use process, first, the main suction cup 4 and the auxiliary suction cup 12 need to be firmly adsorbed on the side wall of the vehicle body 1, and then the angle of the connecting plate 2 is adjusted according to the measurement requirements. By adjusting the first rod clamp 64 and the second rod clamp in the rod connecting device 6 and tightening the first locking bolt 642 and the second locking bolt 66, the vertical or inclined setting between the connecting plate 2 and the vehicle body 1 can be easily achieved. Finally, ensure that all the pull rods and the rod connecting device 6 are in the locked state, and place the vehicle-mounted marking measuring instrument 3 in the slideway 9 of the connecting plate 2 through the I-shaped slide rail 8 to achieve the convenient installation of the vehicle-mounted marking measuring instrument 3.

[0039] Embodiment Two:

[0040] On the basis of Embodiment One, this embodiment optimizes and improves the fixing device of the vehicle-mounted marking measuring instrument 3 in many aspects to enhance its structural strength, stability and usability.

[0041] Aiming at the stress concentration and wear problems that the main rod sleeve 61 may face during long-term use, this embodiment adds a boss 67 design at the key position of the main rod sleeve 61 where the threaded hole 65 is located. This boss 67 not only increases the material area in contact with the threaded hole 65, improves the reliability of the connection, but also effectively disperses the stress generated during thread fastening through its geometric shape, extending the service life of the main rod sleeve 61. In addition, in order to further enhance the supporting ability of the boss 67, reinforcing ribs 68 are cleverly arranged on one side of it. These reinforcing ribs 68 are closely connected to the boss 67 and the main body of the main rod sleeve 61 to form a firm support, effectively improving the overall strength and stiffness of the main rod sleeve 61.

[0042] To ensure a firm connection between the secondary rod disc 62 and the first rod clamp 64, in this embodiment, annularly arrayed anti-slip protrusions 14 are designed on the surface of the secondary rod disc 62. These anti-slip protrusions 14 can significantly increase the friction coefficient of the contact surface with the first rod clamp 64, preventing slip phenomena caused by vibration or external forces. Meanwhile, to further enhance the anti-slip effect, an anti-slip pad 15 is additionally provided between the anti-slip protrusions 14 and the first rod clamp 64. This anti-slip pad 15 is made of a material with a high friction coefficient, which can further increase the frictional force of the contact surface and ensure the stability and safety of the connection.

[0043] To meet the fixing requirements of rods with different shapes, the grooves 641 in this embodiment are designed in two shapes: arc-shaped and V-shaped. The arc-shaped groove 641 is suitable for a tight fit with a cylindrical rod, while the V-shaped groove 641 can better adapt to the fixing requirements of square or irregularly shaped rods. In addition, to further improve the anti-slip performance of the groove 641, anti-slip grooves 16 are opened inside it. The minute textures of these anti-slip grooves 16 can increase the frictional force between the rod and the groove 641, ensuring that the rod is not easily slipped off during the fixing process, thereby improving the stability and reliability of the entire device.

[0044] To reduce the impact damage to the connecting plate 2 and the fixing device caused by vibration during the driving process of the vehicle-mounted marking measuring instrument 3, in this embodiment, shock pads 111 are fixedly arranged at the connection positions of the secondary vertical rod 11 and the main vertical rod 10 with the connecting plate 2. These shock pads 111 are made of high-elasticity materials and have good shock absorption and damping effects. When the vehicle is driving on an uneven road surface, the shock pads 111 can absorb and disperse the vibration energy from the road surface, protecting the connecting plate 2 and the measuring instrument from damage.

[0045] To facilitate the fixed installation of the vehicle-mounted marking measuring instrument 3, in this embodiment, a number of bolt holes for fixing are provided on the connecting plate 2, and the corresponding number of fixing bolts 17 are equipped. The user only needs to place the measuring instrument on the connecting plate 2 and can achieve quick and firm installation by tightening the fixing bolts 17. In addition, to facilitate the user to adjust the horizontal state of the connecting plate 2 during use, two spirit levels 18 perpendicular to each other in direction are fixedly arranged on the connecting plate 2. These two spirit levels 18 respectively indicate the inclination conditions in the horizontal and vertical directions. The user can easily judge and adjust the horizontal state of the connecting plate 2 by observing the position of the bubble in the spirit level 18. This design not only simplifies the adjustment process but also improves the work efficiency and measurement accuracy.

[0046] Working principle: During the use of the utility model, first, the operator fits the main suction cup 4 to the predetermined position of the side wall of the vehicle body 1, and uses its adsorption force to ensure a tight and firm connection between the main suction cup 4 and the vehicle body 1. Then, the auxiliary suction cups 12 are also installed one by one at other key positions of the vehicle body 1 to construct a stable structure with multi-point support, thereby further enhancing the stability of the entire device.

[0047] Next, according to the specific measurement task and road conditions, the operator will begin to adjust the angle of the connecting plate 2. This step is crucial because it is directly related to the accuracy and efficiency of the subsequent measurement work. By carefully operating the first rod clamp 64 and the second rod clamp in the rod connecting device 6, the operator can easily achieve flexible adjustment of the connecting plate 2 in the horizontal and vertical directions. At the same time, the design of the groove 641 on the threaded barrel 63 and the rod clamp can ensure the precise positioning of the rod during the adjustment process. Subsequently, by tightening the first locking bolt 642, the pressure block 643 will quickly and tightly fix the rod clamp on the rod to achieve a preliminary stable locking. In order to further ensure the stability of the connection, the operator will also install and tighten the second locking bolt 66, locking it firmly in the threaded hole 65 of the main rod sleeve 61, thereby forming a solid support system.

[0048] After completing the angle adjustment and locking of the connecting plate 2, the operator will check all the tie rods and the rod connecting devices 6 one by one to ensure that they are in the best locking state. This step is crucial to prevent vibration and shock that may occur during the measurement process. It can effectively protect the measuring instrument from external interference, thereby ensuring the accuracy of the measurement results.

[0049] Finally, the operator places the vehicle-mounted road marking measuring instrument 3 in the I-shaped slide rail 8 on the connecting plate 2. Since the slide rail matches the slideway 9 at the bottom of the measuring instrument, the entire installation process is very convenient. Once the measuring instrument is correctly installed in place, it can start working immediately, providing strong support for the accurate measurement of road markings.

[0050] Although the embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
