Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a marking device for highway construction. Background Art

[0002] During the highway construction process, a marking cart is needed. When the worker pushes the cart, the spray gun on the cart sprays paint onto the road surface to complete the marking operation.

[0003] However, due to the strict maintenance of the spray gun head, if the spray gun head is not cleaned properly after use, the paint in the spray gun will clog the spray gun head, affecting the subsequent use of the spray gun. If the spray gun is cleaned at this time, it will be a waste of time, and the connection between the paint tube of the spray gun and the paint bucket of the cart is mostly bolted. Therefore, the disassembly of the paint tube and the paint bucket of the spray gun is cumbersome, not simple and quick enough, and needs to be improved. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] The utility model provides a technical solution, please refer to Figure 1-3 :

[0023] A marking device for highway construction includes a cart 1, a paint bucket 2 and a spray gun 14. The paint bucket 2 is provided with a chute 5, and a rotating rod 7 is rotatably connected in the chute 5, and the rotating rod 7 is slidably connected to a slider 10. A pressure rod 11 is fixed to the slider 10, a connecting pipe 3 is fixed to the paint bucket 2, and a paint pipe 15 fixed to the spray gun 14 is sleeved on the connecting pipe 3. A fixed disk 16 is fixed to the paint pipe 15, and the pressure rod 11 abuts against the upper surface of the fixed disk 16, and an adjusting member for controlling the pressing force between the pressure rod 11 and the fixed disk 16 is provided on the paint bucket 2. A clamping block 17 is fixed to the fixed disk 16, and a clamping slot 4 is provided on the paint bucket 2. Two clamping blocks 17 and two clamping slots 4 are provided, and a rubber gasket is provided at the part where the clamping block 17 and the clamping slot 4 are engaged. When the clamping block 17 is engaged with the clamping slot 4, the position of the fixed disk 16 can be fixed, so that the fixed disk 16 will not rotate even if subjected to external force.

[0024] Embodiment 2:

[0025] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the adjusting member includes a block 12 slidably connected to the slide groove 5, and the block 12 is connected to the rotating rod 7 by threads, a spring 13 is fixed to the bottom of the block 12, the spring 13 is sleeved on the rotating rod 7, and the bottom of the spring 13 is fixedly connected to the slider 10, and a limiter for limiting the rotating rod 7 is provided on the paint bucket 2. The vertical height of the block 12 at the slide groove 5 can be changed by rotating the rotating rod 7, so that the spring 13 is compressed to different degrees, thereby changing the pressure of the spring 13 on the slider 10, thereby changing the pressure of the pressure rod 11 pressing the fixed plate 16.

[0026] Embodiment three:

[0027] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the stopper includes a handle 8 fixed at the end of a rotating rod 7, a magnetic rod 9 is slidably connected to the handle 8, and a round hole 6 adapted to the magnetic rod 9 is opened on the paint bucket 2. There are multiple round holes 6 distributed at equal angles on the circumference of the paint bucket 2, so that the magnetic rod 9 can be easily inserted into the round hole 6.

[0028] In summary, when replacing a new spray gun 14 provided in this embodiment, the magnetic rod 9 is lifted upwards to make the magnetic rod 9 separate from the round hole 6. At this time, the handle 8 can be rotated, thereby causing the rotating rod 7 to rotate. The block 12 moves upwards in the slide groove 5 until the pressure rod 11 releases the restriction on the fixed plate 16. The fixed plate 16 is lifted upwards, the clamping block 17 is separated from the clamping groove 4, and the paint tube 15 is separated from the connecting tube 3, and the paint tube 5 can be removed from the paint bucket 2.

[0029] Lift the pressure rod 11, put the paint tube 15 of the new spray gun 14 on the connecting tube 3, and the block 17 at the bottom of the fixed plate 16 extends into the slot 4, release the force on the pressure rod 11, and the pressure rod 11 abuts against the upper surface of the fixed plate 16. Turn the handle 8, the block 12 moves down in the slide groove 5 until the block 12 cooperates with the spring 13, so that the pressure rod 11 stably presses the fixed plate 16 down, and the paint tube 15 is connected to the connecting tube 3. At this time, the spray gun 14 can be used normally.

[0030] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
