DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.

[0026] As Figures 1 to 5As shown, this utility model provides a truck height quick measuring ruler, including a ruler cylinder 1, a lifting plate 2 slidably connected inside the ruler cylinder 1, a measuring component 3 provided above the outer surface of the lifting plate 2, an adjusting component 4 provided in the middle of the outer surface of the ruler cylinder 1, a base plate 5 movably connected to the bottom of the ruler cylinder 1, the base plate 5 being fixedly installed to the ground, and sliding grooves 6 with internal and external communication opened on both the front and rear sides of the ruler cylinder 1, and an indicator 7 fixedly connected above the rear side of the lifting plate 2, the outer surface of the indicator 7 being slidably connected to the inside of the sliding groove 6;

[0027] In use, the lifting plate 2 can be easily moved upwards by adjusting the settings of component 4. This allows the structure in the measuring component 3 to contact the truck height, facilitating measurement. Simultaneously, the base plate 5 ensures full contact with the ground during measurement, maintaining vertical stability for the measuring cylinder 1, lifting plate 2, and measuring component 3. Furthermore, a scale can be attached to the rear of the lifting plate 2. During measurement, the truck height is measured by adding the height of the lifting plate 2 to the height of the measuring cylinder 1 and observing the indicator 7. A light can be installed on the rear of the measuring cylinder 1 for convenient nighttime truck height measurement.

[0028] like Figures 1 to 5 As shown, the measuring component 3 includes a mounting sleeve 31. The mounting sleeve 31 has an internal sliding opening that slidably connects to the outer surface of the lifting plate 2. A fixing bolt 32 is threaded through the left side of the mounting sleeve 31, and the outer surface of the fixing bolt 32 overlaps and abuts against the surface of the lifting plate 2. A fixing seat 33 is fixedly connected to the right side of the mounting sleeve 31. A crossbar 36 is provided on the right side of the fixing seat 33. A telescopic shaft 34 is fixedly connected to the middle left side of the crossbar 36. A spring 35 is sleeved on the outer surface of the telescopic shaft 34. A connecting block 332 is fixedly connected to the left end of the telescopic shaft 34 and the spring 35. A groove 331 is provided on the right side of the fixing seat 33. The lower inner surface of the inner wall of 331 is open to the outside. The outer surface of the connecting block 332 is movably connected to the inside of the groove 331. The upper surface of the connecting block 332 overlaps with the upper surface of the inner wall of the groove 331. The left and right sides of the crossbar 36 are fixedly connected to the side of the fixed seat 33. The inside of the movable seat is movably connected to the limit plate 333. The upper and lower surfaces of the fixed seat 33 are fixedly connected to the side away from the movable seat. The outer wall of the block 334 is provided with a semi-circular groove. The inside of the semi-circular groove is connected to the positioning post 335. One end of the positioning post 335 is fixedly connected to the outside of the fixed seat 33. The spring 35 is in a contracted state.

[0029] After use, the worker places the ruler cylinder 1 and the lifting plate 2 flat on the ground and pushes the crossbar 36 to move it so that it can compress and retract the telescopic shaft 34 and the spring 35 again. At this time, the semi-circular groove in the blocking block 334 separates from the outer surface of the positioning post 335. By flipping the limiting plate 333, and then flipping the crossbar 36, it is made to be parallel to the ruler cylinder 1. A magnetic block can be installed between the surface of the crossbar 36 and the ruler cylinder 1. Using the principle of opposite magnetic poles attracting each other, the retracted crossbar 36 is magnetically limited.

[0030] When needed, flipping the crossbar 36 upwards drives the telescopic shaft 34, spring 35, and connecting block 332, causing the connecting block 332 to rotate inside the groove 331. When rotated to the appropriate position, the upper surface of the connecting block 332 contacts the upper surface of the inner wall of the groove 331, creating a blockage, so that the crossbar 36 is perpendicular to the ruler cylinder 1 and the lifting plate 2. Next, pushing the crossbar 36 again compresses the telescopic shaft 34 and spring 35, and flipping the limiting plate 333 so that it contacts the fixed seat 33. Then, releasing the crossbar 36, due to the elasticity of the retracted spring 35, pushes the crossbar 36 to move and drives the limiting plate 333 and the blocking block 334, so that the semi-circular groove in the blocking block 334 contacts the positioning post 335, thus completing the operation. The fixing bolt 32 facilitates the adjustment of the overall height of the mounting sleeve 31, the fixed seat 33, and the crossbar 36.

[0031] like Figures 1 to 5 As shown, the adjustment component 4 includes two connecting blocks 41. A rotating rod 43 is movably connected through the middle of the opposite surfaces of the two connecting blocks 41. A gear 42 is fixedly connected through the middle of the outer surface of the rotating rod 43. Gears 44 are fixedly connected through the left and right sides of the outer surface of the rotating rod 43. A handle is fixedly connected to the left end of the gear 44. A rack plate 21 is fixedly connected to the front of the lifting plate 2. The outer surface of the rack plate 21 meshes with the outer surface of the gear 42. A U-shaped plate 45 is provided below the outer surface of the gear 44. The opposite surface of the U-shaped plate 45 is movably connected to the outer surface of the ruler cylinder 1. Several toothed grooves are provided on the front and rear horizontal surfaces of the U-shaped plate 45. The interior of the toothed grooves meshes with the outer surface of the gear 44. A spring self-resetting hinge 46 is overlapped and pressed against the lower surface of the front and rear horizontal surfaces of the U-shaped plate 45. A limiting block is fixedly connected to the lower surface of the spring self-resetting hinge 46. The outer surface of the limiting block is fixedly connected to the surface of the ruler cylinder 1.

[0032] In use, the worker presses down on the U-shaped plate 45, causing its tooth groove to separate from the outer surface of gear two 44, while simultaneously squeezing and engaging the spring-resetting hinge 46. Then, the worker rotates the rotating rod 43, causing gear two 44 and gear one 42 to rotate. Due to the engagement of gear one 42 with the rack plate 21, the lifting plate 2 moves upward as a whole. Once it reaches the desired position, the worker releases the U-shaped plate 45. At this point, under the elastic action of the spring-resetting hinge 46, the U-shaped plate 45 is pushed to move, causing the tooth groove to re-engage with the outer surface of gear two 44. This engagement process simultaneously restricts the positions of the rotating rod 43, gear two 44, and gear one 42, thereby achieving position locking after the height adjustment of the lifting plate 2.

[0033] The working principle of this truck height rapid measuring ruler will be explained in detail below.

[0034] The worker pushes the crossbar 36 to move it, allowing it to compress and retract the telescopic shaft 34 and spring 35 again. At this time, the semi-circular groove in the blocking block 334 separates from the outer surface of the positioning post 335. By flipping the limiting plate 333 and the crossbar 36, they are brought into a parallel state with the ruler cylinder 1, thus completing the storage operation. When height adjustment is required, the worker presses the U-shaped plate 45, causing its tooth groove to separate from the outer surface of the second gear 44, and compresses the spring self-resetting hinge 46. Subsequently, the worker rotates the rotating rod 43, causing the second gear 44 and the first gear 42 to rotate. Due to the engagement of the first gear 42 with the rack plate 21, the lifting plate 2 moves upward as a whole. When it reaches the desired position, the worker releases the U-shaped plate 45. At this time, under the elastic action of the spring self-resetting hinge 46, the U-shaped plate 45 is pushed to move, causing the tooth groove to re-engage and lock with the outer surface of the second gear 44. This achieves the locking of the lifting plate 2 after height adjustment.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
