[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] Please refer to Figures 1 to 5 According to an embodiment of the present invention, the frame 100 of a line-marking vehicle includes a handlebar assembly 1 and a frame body 2.

[0017] The handle assembly 1 includes a handle 1a and a handle post 1b. The handle post 1b is a telescopic rod, and its lower and upper ends are connected to the frame body 2 and the handle 1a, respectively.

[0018] In this embodiment, the handle includes a handle crossbar 11 and a pair of grips 12, which are respectively connected to both ends of the handle crossbar 11. The aforementioned telescopic rod includes a movable tube 14, a sleeve 15, and a locking mechanism. The upper end of the movable tube 14 is connected to the handle crossbar 11, and the lower part of the movable tube 14 is movably inserted into the sleeve 15; the locking mechanism is used to lock the position of the movable tube 14 in the sleeve 15. The locking mechanism includes a tube clamp 16, which includes a tube clamp body 161 and a locking screw 162; the tube clamp body 161 is fixedly sleeved on the upper end of the sleeve 15, and the movable tube 14 passes through the tube clamp 161 and extends into the sleeve 15. The upper end of the tube clamp body 161 has a notch 1611, and each side of the notch 1611 has a protrusion 1612. The locking screw 162 passes through one of the protrusions 1612 and is screwed to the other protrusion 1612. After turning the locking screw 162, a pair of protrusions 1612 move closer to each other and tighten, thereby locking the movable tube 14.

[0019] The lower end of the handlebar upright 1b is pivotally connected to the frame body 2 via a rotating mechanism. This rotating mechanism enables the handlebar assembly 1 to rotate between the upright position and the folded position, and can releasably lock the handlebar assembly in the upright position.

[0020] The rotating mechanism includes a connecting sleeve 31, a base 32, a pivot 33, and a control lever 34. The connecting sleeve 31 is connected to the lower end of the handlebar upright 1b and has a slot 311. The base 32 is fixed to the frame body 2 and extends into the connecting sleeve 31. The pivot 33 passes through both the connecting sleeve 31 and the base 32. The control lever 34 is connected to the base 32 and can switch between a locked position and an unlocked position.

[0021] When the handle assembly 1 is in the upright position, the control lever 34 is in the locked position and inserted into the slot of the connecting sleeve 31 to prevent the handle assembly 1 from rotating relative to the pivot 33. Figure 1 and Figure 4 As shown. When the control lever 34 is switched to the unlocked position and the handlebar assembly 1 is lifted upward and rotated towards the side of the frame body 2, the slot 311 of the connecting sleeve 31 disengages from the control lever 34, allowing the handlebar assembly 1 to rotate from the upright position to the folded position, as shown. Figure 5 As shown.

[0022] In this embodiment, the control lever 34 is a handle screw, and the base 32 has a threaded hole 324 that mates with the handle screw. The handle screw is screwed into the threaded hole 324, and the control lever switches between a locked position and an unlocked position by tightening and loosening the handle screw. When the handle screw is tightened and in the locked position, the handle screw (specifically, the stepped surface of the handle screw shaft) abuts against the connecting sleeve 31, and the contact friction between the stepped surface of the handle screw and the connecting sleeve 31 prevents the handle assembly 1 from being lifted upward. When the handle screw is in the unlocked position, the handle screw disengages from the connecting sleeve, allowing the handle assembly to be lifted upward.

[0023] In this embodiment, the base 32 has a through hole 323 that mates with the pivot 33. The connecting sleeve 31 has a waist hole 313 that mates with the pivot 33, and the waist hole 313 extends along the height direction of the connecting sleeve 31 so that the handle assembly 1 can be lifted upward. The slot 311 is an L-shaped slot located below the waist hole 313. The first end of the horizontal side 3111 of the L-shaped slot opens onto the rear side of the connecting sleeve, and the second end of the horizontal side 3111 is connected to the first end of the vertical side 3112 of the L-shaped slot, which extends along the height direction of the connecting sleeve 31. When the handle assembly 1 is in the upright position, the control lever 34 extends into the second end of the vertical side 3112 to prevent the handle rod 1b from rotating.

[0024] More specifically, the connecting sleeve 31 includes a top plate 31a and a pair of side plates 31b, the tops of the pair of side plates 31b being connected to the two opposite sides of the top plate 31a respectively; the number of waist holes 313 and the number of slots 311 are both a pair, and the pair of waist holes 313 and the pair of slots 311 are respectively provided on the pair of side plates 31b.

[0025] In this embodiment, the frame body 2 includes a longitudinal beam 21, a crossbeam 22, a front wheel axle 23, a rear wheel axle 24, a pair of front wheels 25, and a pair of rear wheels 26. A base 32 is fixed to the front end of the longitudinal beam 21. The front wheel axle 23, the crossbeam 22, and the rear wheel axle 24 are sequentially arranged on the longitudinal beam 21 from front to rear and connected to the longitudinal beam 21. The pair of front wheels 25 are rotatably mounted on both ends of the front wheel axle 23, and the pair of rear wheels 26 are rotatably mounted on both ends of the rear wheel axle 24.

[0026] Furthermore, the frame body 2 is provided with a positioning part 27, which is used to cooperate with the handlebar upright 1b to releasably position the handlebar assembly 1 in the fallen position. In this embodiment, the positioning part 27 is a positioning groove, which is formed on the top of a vertical plate 28, and the vertical plate 28 is fixed to the frame body 2.

[0027] Figure 6 A perspective view of a line-marking vehicle according to an embodiment of the present invention is shown. Figure 6As shown, a marking vehicle according to an embodiment of the present invention includes a sprayer 200, a high-pressure hose 300, a spray gun 400, a spray gun bracket 500, a pressing handle 600, a control cable 700, and the aforementioned vehicle frame 100.

[0028] The paint sprayer 200 and the spray gun holder 500 are respectively mounted on the frame body 2 of the vehicle frame 100. The spray gun 400 is mounted on the spray gun holder 500 and is connected to the paint sprayer 200 through a high-pressure pipe 300. In this embodiment, the spray gun holder 500 is located at the rear end of the frame body 2, the spray gun 400 extends rearward from the frame body 2, and the outlet of the spray gun 400 faces downward.

[0029] A pressing handle 600 is fixed to the handle 1a. One end of the control cable 700 is connected to the pressing handle 600, and the other end is connected to the switch portion 501 of the spray gun bracket 500. In one specific embodiment, the switch portion 501 is a rotating rod pivotally connected to the spray gun bracket body 502. When the pressing handle 600 is pressed, the control cable 700 is pulled, the switch portion 501 rotates, and thus triggers the switch of the spray gun 400 to open.

[0030] When in operation, turn on the switch of the sprayer 200, press the handle 600, and the control cable 700 is pulled, which actuates the switch 501 of the spray gun bracket 400, triggering the switch of the spray gun 400 to open. Push the hand-held frame 100 forward to perform spraying and marking operations.

[0031] To accommodate different worker heights, the locking screw 162 of the pipe clamp 16 can be loosened, allowing the movable tube 14 to slide within the sleeve 15, thus adjusting and fixing the height of the movable tube 14. When folding, packing, or storing the frame, retract the handlebar upright 1b to its shortest length, loosen the control lever 34 (i.e., the handle screw), and move the handle screw outward along the threaded hole 324. Then, pull the handle assembly 1 upward, and the handle assembly 1, along with the waist hole 313 of the connecting sleeve 31, moves upward. The slot 311 disengages from the handle screw, and rotating the handle assembly 1 backward allows the handle assembly to be folded.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
