[0002] At present, spraying machines are widely used in the processing and manufacturing industries. They use high-pressure gas as a power source to move the mechanism for spraying. In order to meet the needs of spraying, an adjustment knob for adjusting the gas pressure is often provided on the spraying machine. The gas pressure of multiple gears of the spraying machine can be adjusted by adjusting the knob. The existing adjustment knob is provided with an adjustment rotation damping device so that there is a sense of rotational damping during the rotation process to facilitate the use of rotation adjustment. However, during the rotation adjustment process, the gear position of the adjustment knob is not positioned properly, and the gear rotation is not accurate, which affects the adjustment use of the adjustment knob. Therefore, it is very necessary to improve the defects of the existing adjustment knob. Summary of the invention

[0003] The purpose of the utility model is to solve the problems raised in the above background technology and provide a positioning structure for an adjusting knob on a spraying machine.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a positioning structure for an adjusting knob on a spray machine, comprising a mounting plate and an adjusting knob arranged on the mounting plate, the adjusting knob being rotatably connected to the mounting plate through a mounting rod; a mounting hole is arranged on the mounting plate, a positioning device is arranged in the mounting hole, and a plurality of positioning grooves corresponding to the positioning device are arranged on the adjusting knob; the positioning device comprises a spring and a positioning steel ball, the spring maintains an elastic force against the positioning steel ball, so that part of the positioning steel ball is in the positioning groove, and as the adjusting knob rotates, the positioning steel ball is kept in the positioning groove under the elastic force of the spring.

[0005] In the above-mentioned positioning structure of the adjusting knob on the sprayer, a mounting column is provided on the mounting plate, a mounting hole is provided in the mounting column, a positioning device is provided in the mounting hole, and can form a positioning abutment with the positioning groove on the adjusting knob.

[0006] In the above-mentioned positioning structure using an adjusting knob on a sprayer, the mounting column and the mounting plate are designed as an integrated structure.

[0007] In the above-mentioned positioning structure for adjusting the knob on the sprayer, the positioning steel ball is partially located in the inner hole of the spring.

[0008] In the above-mentioned positioning structure for an adjusting knob on a sprayer, a boss is provided on the adjusting knob to form a block with the mounting column.

[0009] The utility model has the following beneficial effects:

[0010] After the adjusting knob is rotated to adjust the gear, the positioning steel ball in the positioning device partially presses against the positioning groove on the adjusting knob under the pressing elastic force of the spring, so that the adjusting knob is positioned after being rotated to adjust the gear, thereby solving the defects in the use of the existing adjusting knob and facilitating use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a stereogram of the utility model. DETAILED DESCRIPTION

[0013] The utility model is further described in conjunction with the accompanying drawings.

[0014] See also Figure 1 , Figure 2 The utility model provides a positioning structure for an adjusting knob on a sprayer, comprising a mounting plate 1, an adjusting knob 2 arranged on the mounting plate 1, the adjusting knob 2 being rotatably connected to the mounting plate 1 through a mounting rod 3; a mounting hole 4 is arranged on the mounting plate 1, and specifically, a mounting column 9 is arranged on the mounting plate 1, the mounting hole 4 is arranged in the mounting column 9, a positioning device 5 is arranged in the mounting hole 4, and a plurality of positioning grooves 6 are arranged on the adjusting knob 2, and as the adjusting knob 2 rotates, the positioning grooves 6 thereon can respectively correspond to the positioning device 5 against each other.

[0015] The positioning device 5 includes a spring 7 and a positioning steel ball 8. The spring 7 maintains an elastic force against the positioning steel ball 8, so that the positioning steel ball 8 is partially located in the positioning groove 6. The positioning device 5 is arranged in the mounting hole 4 and can form a positioning abutment with the positioning groove 6 on the adjusting knob 2; as the adjusting knob 2 rotates, the positioning steel ball 8 is partially maintained in the positioning groove 6 under the elastic force of the spring 7.
