[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] Reference Figures 1 to 10 A spray gun stand includes a base frame 100 and a spray gun connecting rod 200. The base frame 100 includes a connecting seat 110 and a crossbar 120. The crossbar 120 is arranged in the left-right direction and connected to the connecting seat 110. The crossbar 120 has a plurality of through-holes 121 extending through the front and rear ends, and the through-holes 121 are arranged along the length of the crossbar 120. The spray gun connecting rod 200 has a plurality of through-holes 121 corresponding to each other. The spray gun connecting rod 200 is arranged in the front-to-back direction and is disposed on the front side of the crossbar 120. The rear end of the spray gun connecting rod 200 is passed through the corresponding through-holes 121 and is fixed to the crossbar 120. The spray gun connecting rod 200 is provided with a powder hose passage 210, which extends in the front-to-back direction. The spray gun connecting rod 200 is provided with a pipe outlet 230 and a first pipe inlet 220, which are respectively connected to the front and rear ends of the powder hose passage 210. The first pipe inlet 220 is provided on the rear end surface of the spray gun connecting rod 200.

[0038] In the aforementioned spray gun stand, the base frame 100 utilizes a single crossbar 120 to connect the various spray gun connecting rods 200. The spray gun connecting rods 200 are directly plugged into the through-holes 121 of the crossbar 120. This results in a simple overall structure and a small footprint. Furthermore, since a cross-hook is eliminated for connecting multiple rods and the spray gun connecting rods 200, assembly is also relatively easy. Furthermore, the spray guns can be secured to the spray gun connecting rods 200, and the powder hose that supplies the spray guns with spray powder can be inserted into the powder hose passage 210 from the rear side of the crossbar 120 through the first pipe inlet 220, and then connected to the spray guns through the pipe outlet 230. This facilitates connection of the powder hose and creates a neatly arranged pipeline layout.

[0039] In this embodiment, a second pipe inlet 240 communicating with the powder hose passage 210 is further provided at the rear of the spray gun connecting rod 200. The second pipe inlet 240 is formed on the circumference of the spray gun connecting rod 200 and is located in front of the crossbar 120. If the powder hose cannot be directly introduced through the first pipe inlet 220, such as when blocked by the connecting base 110, the powder hose can enter through the second pipe inlet 240. The addition of the second pipe inlet 240 increases the number of pipe inlets and enhances the flexibility of the powder hose connection.

[0040] In the embodiment, the rear end of the spray gun connecting rod 200 is detachably connected to the crossbar 120 via a fixing member 300. The fixing member 300 is provided with a fastening structure that secures the spray gun connecting rod 200 and the fixing member 300 together. The above structure facilitates the fixing and removal of the spray gun connecting rod 200, facilitating subsequent replacement and maintenance. Of course, it is conceivable that in some embodiments, the spray gun connecting rod 200 is not limited to being fixed by the fixing member 300. For example, the spray gun connecting rod 200 can be installed and fixed by welding or by tightly fitting with the through-hole 121.

[0041] In an embodiment, Figure 2 、 Figure 5 as well as Figure 6 As shown, the fixing member 300 is a clamp, and the spray gun connecting rod 200 is inserted into the clamp. The fastening structure is a first threaded fastener 310 inserted into the two ends of the clamp. The first threaded fastener 310 is used to tighten and loosen the clamp to tighten and loosen the spray gun connecting rod 200. Using a tightening structure to secure the spray gun connecting rod 200 has low requirements for the matching dimensions and is easy to implement.

[0042] In an embodiment, the first threaded fastener 310 can be a screw, with one of the two ends of the clamp provided with a through hole and the other provided with a screw hole. The first threaded fastener 310 passes through the through hole and is threadedly connected to the screw hole. Tightening and loosening the first threaded fastener 310 can tighten and loosen the clamp. Of course, it is conceivable that the first threaded fastener 310 can also be a combination of a bolt and a nut, with through holes provided at both ends of the clamp. The bolt passes through the two through holes and is then connected to the nut. Tightening and loosening the nut can tighten and loosen the clamp.

[0043] In other embodiments, Figures 7 to 10 As shown, the spray gun connecting rod 200 can also be fixed by the following structure: the fixing member 300 is provided with a mounting hole 320, the mounting hole 320 is aligned with the through-hole 121, the spray gun connecting rod 200 is inserted into the mounting hole 320, the hole wall of the mounting hole 320 is provided with a threaded through-hole 330, and the fastening structure is a screw threadedly connected to the threaded through-hole 330. The above structure is simple and easy to implement to fix the spray gun connecting rod 200. Specifically, the screw threadedly connected to the threaded through-hole 330 can be directly pressed against the circumference of the spray gun connecting rod 200, or the circumference of the spray gun connecting rod 200 is provided with a corresponding screw hole or socket to cooperate with the screw to achieve the fixation of the spray gun connecting rod 200.

[0044] In this embodiment, a circular portion 410 is provided around the periphery of the first pipe inlet 220, and the circular portion 410 has abutment rounded corners. With this structure, the powder hose entering through the first pipe inlet 220 can abut against the abutment rounded corners, preventing the powder hose from directly abutting against the sharp edges of the first pipe inlet 220 and providing better protection for the powder hose.

[0045] In the embodiment, the second pipe inlet 240 is a strip-shaped opening extending along the length direction of the spray gun connecting rod 200. Thus, the powder hose entering from the second pipe inlet 240 has room to move forward and backward, reducing the possibility of being folded.

[0046] In the embodiment, the fixing member 300 is provided on the front end surface of the crossbar 120, the rear end surface of the crossbar 120 is provided with a supporting member 400, the annular portion 410 is provided on the supporting member 400, and the fixing member 300, the crossbar 120, and the supporting member 400 are penetrated by a second threaded fastener 500, which is used to clamp the fixing member 300 and the supporting member 400 to tighten the crossbar 120. With the above structure, the fixing member 300 and the supporting member 400 can be fixed simultaneously by the second threaded fastener 500, which has a simple structure and a firm fixation.

[0047] In an embodiment, the second threaded fastener 500 may be a screw, and corresponding fixation can be achieved by providing a screw hole in the abutting member 400 or the fixing member 300. Of course, it is conceivable that the second threaded fastener 500 may also be fixed by a combination of a bolt and a nut.

[0048] In an embodiment, when the fixing member 300 is a clamp, the second threaded fastener 500 can pass through the end surface of the clamp for fixing. The fixing member 300 can also be a flange structure, and the second threaded fastener 500 can pass through the flange of the flange structure for fixing.

[0049] In an embodiment, the spray gun connecting rod 200 includes a connecting straight pipe 250 and a spray gun bracket 260. The powder hose passage 210 is a lumen of the connecting straight pipe 250. The first pipe inlet 220 and the pipe outlet 230 are the two end openings of the connecting straight pipe 250. The connecting straight pipe 250 is arranged in a front-to-back direction, and the spray gun bracket 260 is connected to the front end of the connecting straight pipe 250. The spray gun can be fixed to the spray gun bracket 260, and the powder hose connected to the spray gun can pass through the connecting straight pipe 250 and then be connected to an external powder supply center. It is conceivable that the spray gun connecting rod 200 is not limited to the above-mentioned structure. Those skilled in the art can reasonably configure its structure and shape according to actual conditions.

[0050] In an embodiment, the vertical position of the cross bar 120 relative to the connecting seat 110 is adjustable, so as to facilitate position adjustment for use.

[0051] In the embodiment, the connecting base 110 is provided with vertically arranged gear holes, and the cross bar 120 and the gear holes are penetrated with threaded fasteners for fastening the two. The cross bar 120 can be installed at the gear holes at any height position to achieve vertical position adjustment. Of course, it is conceivable that the cross bar 120 can also achieve vertical position adjustment through other structures. For example, the cross bar 120 is connected to the connecting base 110 through some screw mechanisms, and the vertical position of the cross bar 120 is adjusted by rotating the screws. It is understandable that in this field, there are many implementation methods for achieving component position adjustment along a predetermined direction, and those skilled in the art can configure according to actual conditions.

[0052] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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 of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
