[0001] The utility model relates to the technical field of paint spraying, in particular to a steel component paint spraying device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Because steel structures are prone to oxidation reactions with oxygen and water vapor in the air during storage and use, forming a layer of rust on the surface, a layer of anti-corrosion paint is usually sprayed on the surface of the steel structure. The spraying of anti-corrosion paint is usually done by workers using a handheld spray device. However, the length of the current handheld spray device is fixed, which is not convenient for workers to spray parts of the steel structure.

[0003] In response to the above technical problems, the applicant has retrieved some prior art, such as the Chinese patent with patent publication number CN216173371U, which mainly allows the slide bar to sink into the hand-held tube by pulling two pull ropes, and the spring can cause the slide bar to slide out of the hand-held tube, changing the overall length of the hand-held tube and the slide bar; by pulling one of the pull ropes, the spray head can be rotated on the slide bar, changing the spraying direction of the spray head. However, when the prior art equipment is spraying the angle inside the I-beam, it is necessary to pull the pull rope back and forth to adjust the spraying direction of the spray head in order to spray the angle inside the I-beam, which is complicated to operate and inconvenient to use. 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] See also Figure 1-Figure 5 A paint spraying device for steel parts, comprising a hand-held barrel 1, an adjustable slide bar 2 is mounted on the hand-held barrel 1, a locking ring 3 is mounted on one end of the hand-held barrel 1 close to the slide bar 2, the locking ring 3 clamps the slide bar 2, a mounting block 4 is arranged on the slide bar 2, a rotating plate 5 is rotatably mounted on both sides of the mounting block 4, a nozzle 6 is mounted on the rotating plate 5, and the nozzle 6 is connected to a connecting pipe 7, a moving groove 10 is opened inside the slide bar 2, a first spring 12 is arranged inside the moving groove 10, one end of the first spring 12 is connected to a push plate 11, a pull rope 8 is arranged on the rotating plate 5, and the pull rope 8 passes through the moving groove 10 and is fixedly connected to the push plate 11. A locking knob 14 is arranged on the locking ring 3.

[0022] It should be noted that, in the initial state, the rotating plates 5 on both sides of the mounting block 4 are in a collinear state (eg Figure 2 ), at this time, the nozzle 6 on the rotating plate 5 can spray the outer wall of the steel structure. Pull the pull rope 8, the pull rope 8 will pull the rotating plate 5, so that the rotating plate 5 rotates, and the rotating plate 5 will fold inside the mounting block 4. At this time, the spraying angle of the roller 9 is gradually changing, and the roller 9 can spray the inside of the steel structure.

[0023] In actual use, the rebound of the first spring 12 will drive the rotating plate 5 to return to the initial state, and indirectly pull the pull rope 8, so that the roller 9 can evenly spray the inside of the steel structure. It is easy to use and has high practicality.

[0024] Specifically, the pull rope 8 is located inside the slide rod 2 and slides.

[0025] See also Figure 2 The hand-held tube 1 is connected to one end of the second spring 13, the other end of the second spring 13 is connected to the slide bar 2, and the second spring 13 is located in the hand-held tube 1. It should be noted that the length of the hand-held tube 1 and the slide bar 2 can be adjusted and fixed by the cooperation of the second spring 13 and the locking ring 3.

[0026] See also Figure 5 , a roller 9 is rotatably mounted on the mounting block 4. It should be noted that during the spraying process of the inside of the I-beam, since the hand-held cylinder 1 has a certain weight, the worker's hands will become numb if the hand-held cylinder 1 is held for a long time to spray the inside of the I-beam. If the roller 9 is pressed against the inner wall of the I-beam and the roller 9 is pushed, the weight required for the hand-held cylinder 1 to be held by the worker can be reduced.

[0027] Specifically, one end of the connecting pipe 7 is connected to the nozzle 6, and the other end of the connecting pipe 7 is connected to the pump body.

[0028] The implementation principle of the utility model is as follows: when in use, if it is necessary to adjust the overall length of the hand-held tube 1 and the slide bar 2, the locking knob 14 on the locking ring 3 is loosened to make the locking ring 3 invalid for fixing the slide bar 2. At this time, under the push of the second spring 13, the slide bar 2 slides out from the inside of the locking ring 3, and the overall length of the hand-held tube 1 and the slide bar 2 is extended; if it is necessary to shorten the overall length of the hand-held tube 1 and the slide bar 2, the slide bar 2 is pushed into the locking ring 3 to compress the second spring 13. At this time, the locking knob 14 on the locking ring 3 is tightened to make the locking ring 3 clamp the slide bar 2 and the locking ring 3 fix the overall length of the hand-held tube 1 and the slide bar 2.

[0029] When the equipment sprays the inside of the I-beam, the pump body is first started to allow the paint to enter the spray head 6 through the connecting pipe 7. The spray head 6 sprays the inside of the I-beam, and then the roller 9 on the mounting block 4 is abutted against the inner wall of the I-beam and the roller 9 is pushed to spray along the inner wall of the I-beam. During the spraying process, the pull rope 8 is indirectly pulled, and the pull rope 8 can drive the push plate 11 to move inside the moving groove 10, so that the first spring 12 is compressed. At this time, the rotating plate 5 gradually rotates under the pull of the pull rope 8, and the rotation of the rotating plate 5 drives the spraying angle of the spray head 6 to gradually change (see Figure 5 ), while the spraying angle of the nozzle 6 changes, the nozzle 6 can spray the inner wall of the I-beam and the angle of the I-beam. The device has high spray uniformity on the inner angle of the I-beam, good spraying effect, and easy operation.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
