Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a trolley for use on a spray painting machine. Background Technology

[0002] A spray painting machine is a specialized coating equipment that uses spraying technology and is widely used in the processing and manufacturing industry. The spray painting machine can pressurize the paint it sucks in and deliver the paint to the spray gun of the spray painting machine through a high-pressure hose. The spray gun then atomizes the paint and releases it onto the surface of the object being coated.

[0003] When operating a spray painting machine, the machine is usually placed on a trolley. The operator can then use the trolley to move the machine to the area to be painted, depending on the work requirements. However, existing spray painting machine trolleys typically cannot be height-adjusted, which may not suit the usage habits of operators of different heights, easily reducing spraying efficiency. Furthermore, the trolleys have limited functionality and are inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to provide a trolley for a spraying machine.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A trolley for a spray painting machine includes a frame body, wheels and a mounting bracket, wherein the wheels are disposed at the bottom of the frame body and the mounting bracket is mounted on the frame body for mounting the spray painting machine;

[0007] The main body of the frame includes a telescopic rod, a handrail, and a bottom bracket. One end of the telescopic rod is connected to the handrail, and the other end of the telescopic rod is detachably connected to the bottom bracket. The telescopic rod can extend or shorten along its own axial direction to adjust the height of the handrail relative to the bottom bracket.

[0008] In one embodiment, the telescopic rod includes a connecting rod, a sleeve, and a locking structure. One end of the connecting rod extends into the sleeve and is slidably connected to the sleeve. The connecting rod is movable along the axial direction of the sleeve, and the locking structure locks the relative position of the connecting rod and the sleeve.

[0009] In one embodiment, the locking structure includes a positioning element and a limiting post.

The positioning element and the limiting post are arranged at intervals along the axial direction of the connecting rod. The mating tube can abut between the positioning element and the limiting post to limit the displacement of the connecting rod relative to the axial direction of the sleeve.

[0010] In one embodiment, the sleeve has an insertion hole, and the positioning member includes an elastic part and a positioning protrusion. The elastic part is fixed to the inner wall of the connecting rod and connected to the positioning protrusion. The positioning protrusion can move along the axial direction of the mating tube under the drive of the connecting rod, and squeeze the elastic part under the action of the inner wall of the mating tube, so that the positioning protrusion contracts relative to the outer wall of the connecting rod, and resets under the elastic action of the elastic part, and the hole wall of the insertion hole is inserted and fitted.

[0011] In one embodiment, the mounting bracket is fixed to the sleeve and forms a preset distance with the bottom bracket.

[0012] In one embodiment, the mounting bracket includes two mounting tubes, which are respectively fixed to the corresponding telescopic rods, so that the mounting fitting tubes of the spraying machine can be detachably connected by hand-tightening bolts.

[0032] Please see Figure 1 and Figure 2 An embodiment of this utility model provides a trolley 100 for use on a spraying machine 200. The trolley 100 includes a frame body 10, wheels 30 and mounting brackets 20. The wheels 30 are disposed at the bottom of the frame body 10, and the mounting brackets 20 are mounted on the frame body 10 for installation on the spraying machine 200.

[0033] The frame body 10 includes a telescopic rod 11, a handrail 12, and a bottom support 13. One end of the telescopic rod 11 is connected to the handrail 12, and the other end is detachably connected to the bottom support 13. The telescopic rod 11 can extend or shorten along its own axial direction to adjust the height of the handrail 12 relative to the bottom support 13. Thus, the height of the handrail 12 can be adjusted via the telescopic rod 11 to accommodate operators of different heights, allowing the handrail 12 to be adjusted to a height that the operator is accustomed to, thereby improving the efficiency of the painting operation.

[0034] During spraying operations, when the trolley 100 moves, the bottom support 13 is raised off the ground by the handle 12, allowing the wheels 30 to move. When the trolley 100 stops, the bottom support 13 rests against the ground, and the bottom support 13, together with the wheels 30, supports the trolley 100, ensuring it remains stably stationary. The bottom support 13 is detachable, allowing for the replacement of different styles to meet various needs. This makes the trolley 100 versatile and improves its convenience.

[0035] In this embodiment, the telescopic rod 11 is configured as a sleeve structure to realize the telescopic function of the telescopic rod 11. The telescopic rod 11 includes a connecting rod 111, a sleeve 112, and a locking structure 113. One end of the connecting rod 111 extends into the sleeve 112 and is slidably connected to the sleeve 112. The connecting rod 111 can move along the axial direction of the sleeve 112, and the relative position of the connecting rod 111 and the sleeve 112 is locked by the locking structure 113. When the telescopic rod 11 extends to the required length, the length of the telescopic rod 11 can be locked by the locking structure 113. There are two telescopic rods 11, and the two telescopic rods 11 are connected by a crossbar 14.

[0036] Not limited to this, in other embodiments, the relative extension and retraction of the telescopic rod 11 can also be achieved by the rotational engagement of the internal and external threads, or by setting a gas spring structure to achieve the extension and retraction function of the telescopic rod 11, etc., which will not be elaborated here.

[0037] Specifically, the connecting rod 111 is connected to the handrail 12, the sleeve 112 is connected to the bottom bracket 13, and the connecting rod 111 and the handrail 12 are connected as one unit.

[0038] In one embodiment, the locking structure 113 includes a positioning element 1131 and a limiting post 1132. The sleeve 112 includes a mating tube 1121, which is fixed inside the sleeve 112 and partially extends out of the sleeve 112. The positioning element 1131 and the limiting post 1132 are arranged at intervals along the axial direction of the connecting rod 111. The mating tube 1121 can abut between the positioning element 1131 and the limiting post 1132 to limit the displacement of the connecting rod 111 relative to the sleeve 112 in the axial direction. That is, the positioning element 1131 restricts the connecting rod 111 from moving away from the sleeve 112, and the limiting post 1132 restricts the connecting rod 111 from further extending into the sleeve 112. Thus, the positioning element 1131 and the limiting post 1132 cooperate with each other to lock the relative position of the connecting rod 111 and the sleeve 112 in the axial direction.

[0039] Not limited to this, in other embodiments, the locking structure 113 may also be configured as a locking bolt connection, etc.

[0040] In this embodiment, a groove is provided at one end of the mating tube 1121 near the limiting post 1132. The groove wall is matched with the limiting post 1132. The groove is arc-shaped, which can restrict the circumferential rotation of the connecting rod 111 relative to the mating tube 1121, thereby restricting the circumferential displacement of the connecting rod 111 relative to the sleeve 112.

[0041] like Figure 3 and Figure 4 As shown, in one embodiment, the sleeve 112 is provided with an insertion hole 1122, and the positioning member 1131 includes an elastic part 11311 and a positioning protrusion 11312. The elastic part 11311 is fixed to the inner wall of the connecting rod 111 and connected to the positioning protrusion 11312. The positioning protrusion 11312 can move along the axial direction of the mating tube 1121 under the drive of the connecting rod 111, and squeeze the elastic part under the action of the inner wall of the mating tube 1121, so that the positioning protrusion 11312 shrinks relative to the outer wall of the connecting rod 111 and is inserted into the hole wall of the insertion hole 1122.

[0042] Specifically, there is one insertion hole 1122, and the positioning protrusion 11312 can move from the edge of the sleeve 112 to the insertion hole 1122 to realize two-level height adjustment of the telescopic rod 11.

[0043] Of course, the number of insertion holes 1122 can also be set to two, with the two insertion holes 1122 arranged at intervals along the axial direction of the sleeve 112 to realize three-level height adjustment of the telescopic rod.

[0044] In this embodiment, the elastic part 11311 is configured as a spring sheet, and the elastic part 11311 is integrally connected with the positioning protrusion 11312; of course, in other embodiments, the elastic part 11311 can also be configured as a return spring or elastic rubber, etc., and the elastic part 11311 and the positioning protrusion 11312 can also be configured separately.

[0045] like Figure 1 As shown, in one embodiment, the bottom support 13 is configured as two bottom curved tubes 131, which are spaced apart and connected to the corresponding telescopic rods 11. The bottom curved tubes 131 have a hollow tubular structure, which makes the trolley 100 lighter.

[0046] like Figure 1 and Figure 5 As shown, specifically, the bottom bend 131 and the sleeve 112 are detachably connected by a hand-tightening bolt 15. A first connecting block 1123 is welded and fixed inside the sleeve 112 near the bottom support 13. When the end of the sleeve 112 is inserted into the bottom support 13, the hand-tightening bolt 15 can pass through the bottom bend 131 and the sleeve 112 and be threadedly connected to the first connecting block 1123, thereby achieving a detachable connection between the bottom support 13 and the telescopic rod 11. The use of the hand-tightening bolt 15 makes installation and disassembly more convenient for operators.

[0047] like Figure 2 As shown, in another embodiment, the bottom support 13 has a support platform 132 for supporting external objects. The bottom support 13 with the support platform 132 is detachably connected to the telescopic rod 11 by a hand-tightening bolt 15. Of course, in other embodiments, ordinary bolts or screws can also be used to achieve the detachable connection between the telescopic rod 11 and the bottom support 13.

[0048] In one embodiment, the mounting bracket 20 is fixed to the sleeve 112 and forms a preset distance with the bottom bracket 13. Compared with existing trolleys, the trolley 100 provided by this utility model allows the sprayer 200 to be mounted higher, so that there is enough space between the sprayer 200 and the ground, facilitating the passage of the sprayer 200's pipeline.

[0049] In one embodiment, the mounting bracket 20 includes two mounting tubes 21, which are respectively fixed to the corresponding telescopic rods 11 for the mounting fitting tubes 201 of the spraying machine 200 to be inserted and fitted.

[0050] like Figure 1 and Figure 6As shown, the mounting pipe 21 and the mounting mating pipe 201 are detachably connected by a hand-tightening bolt 15. A second connecting block 202 is welded and fixed inside the mounting mating pipe 201. After the mounting pipe 21 and the mounting mating pipe 201 are inserted and mated, the hand-tightening bolt 15 can pass through the mounting pipe 21 and the mounting mating pipe 201 in sequence and be threadedly connected to the second connecting block 202, so as to detachably fix the mounting mating pipe 201 to the mounting bracket 20, thereby mounting the sprayer 200 on the trolley 100.

[0051] In one embodiment, the trolley 100 also includes a suspension rod 40, which is mounted on the frame body 10 and located near the handrail 12, so that the operator can hang and place some accessories of the spraying machine 200, such as power cords or discharge pipes.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the patent protection scope of this utility model should be determined by the appended claims.
