Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] Example 1

[0024] See also Figure 1-6 The utility model provides the following technical solutions: a steel structure building painting device, including a box body 1, a box door 3 is arranged on one side of the box body 1, a placing component 4 is arranged on the side wall of the box door 3, a rotating fixing mechanism 6 is arranged inside the box body 1, a drying mechanism 5 is arranged inside the box body 1 and above the rotating fixing mechanism 6, a paint spraying pipe 2 is connected to both sides of the box body 1 and below the rotating fixing mechanism 6, and a receiving component 7 is arranged inside the box body 1 and below the paint spraying pipe 2.

[0025] Specifically, the receiving assembly 7 includes a receiving box 73, a pressure block 74, a fixed block 75, a rotating screw 76, a return spring 77 and a pressure groove 78. The receiving box 73 is arranged inside the box body 1 and below the paint spray pipe 2. The inner wall of the box body 1 and both ends above the receiving box 73 are connected with fixed blocks 75. The rotating screw 76 is threadedly connected to the fixed block 75. A return spring 77 is connected below the fixed block 75 and at the periphery of the rotating screw 76. The end of the return spring 77 away from the fixed block 75 is connected to the pressure block 74. A pressure groove 78 is arranged on the side wall of the receiving box 73 and at the position corresponding to the pressure block 74.

[0026] By adopting the above technical solution, after the receiving box 73 is placed inside the box body 1, the rotating screw 76 is rotated to make it rotate and move along the fixed block 75. The movement of the rotating screw 76 drives the pressure block 74 to move and the restoring spring 77 to stretch. When the pressure block 74 completely enters the pressure groove 78, the rotation of the rotating screw 76 is stopped. Under the action of the pressure block 74, the receiving box 73 can be pressed and fixed. In the subsequent painting process of the building steel structure, the excess paint on the building steel structure falls into the receiving box 73 under the action of gravity for collection, so as to prevent the paint from dripping into the box body 1, causing the internal environment of the box 1 to be polluted and the paint to be wasted.

[0027] Specifically, one end of the pressing block 74 close to the box body 1 is connected to a guide slide block, and a guide groove is provided on the inner wall of the box body 1 at a position corresponding to the guide slide block.

[0028] By adopting the above technical solution, the movement of the pressing block 74 drives the guide slider to move inside the guide slot. Under the sliding cooperation of the guide slider and the guide slot, a guiding effect can be provided for the movement of the pressing block 74, thereby improving the stability of the movement of the pressing block 74.

[0029] Specifically, the receiving assembly 7 further includes a positioning groove 71 and a positioning protrusion 72. The inner wall of the box body 1 is connected with the positioning protrusion 72. The positioning groove 71 is provided below the receiving box 73 and at a position corresponding to the positioning protrusion 72.

[0030] By adopting the above technical solution, the positioning groove 71 is aligned with the position of the positioning protrusion 72, and then the receiving box 73 is moved into the box body 1. With the cooperation of the positioning protrusion 72 and the positioning groove 71, a guiding effect can be provided for the movement and insertion of the receiving box 73.

[0031] When the present embodiment is used, the box door 3 is first opened, the positioning groove 71 is aligned with the position of the positioning protrusion 72, and then the receiving box 73 is moved into the box body 1. With the cooperation of the positioning protrusion 72 and the positioning groove 71, a guiding effect can be provided for the movement and insertion of the receiving box 73. When the receiving box 73 is fully inserted into the box body 1, the rotating screw 76 is rotated to rotate and move along the fixing block 75. The movement of the rotating screw 76 drives the pressing block 74 to move and the restoring spring 77 to stretch. When the pressing block 74 completely enters the pressing groove 78, the rotation of the rotating screw 76 is stopped. Under the action of the pressing block 74, the receiving box 73 can be pressed and fixed, and then the building steel structure to be painted is placed in the box body 1, and the rotating fixing mechanism 6 is used to fix the building steel structure. The steel structure is fixed, and then the box door 3 is closed, and then the paint spraying pipe 2 is connected to the external paint source, and the paint spraying pipe 2 is used to spray the external paint onto the steel structure. During the painting process of the steel structure, the excess paint on the steel structure falls into the receiving box 73 under the action of gravity for collection, so as to prevent the paint from dripping into the box 1, causing the internal environment of the box 1 to be polluted and the paint wasted. After the painting of the steel material near one end of the paint spraying pipe 2 is completed, the rotating fixing mechanism 6 is used to drive the steel material to rotate, so as to facilitate the subsequent painting operation on the other end of the steel material. In the process of driving the steel material to rotate by the rotating fixing mechanism 6, the drying mechanism 5 can dry the sprayed paint.

[0032] Example 2

The fixing box 41 is connected to the side wall of the box door 3. The placement box 42 is arranged inside the fixing box 41. The upper ends of the placement box 42 are connected to the connecting rod 44. The fixing cylinder 45 is connected to the inner wall of the fixing box 41 and at the position corresponding to the connecting rod 44. A connecting spring 46 is connected between the connecting rod 44 and the fixing cylinder 45. The partition plate 43 is connected inside the placement box 42. The lower part of the placement box 42 is connected to a pull rod.

[0034] Specifically, both sides of one end of the connecting rod 44 close to the fixed cylinder 45 are connected to limit sliders, and a limit slide groove is provided on the inner wall of the fixed cylinder 45 at a position corresponding to the limit slider.

[0035] By adopting the above technical solution, the movement of the connecting rod 44 drives the limit slider to move inside the limit slide groove. When the limit slider fits the inner wall of the limit slide groove, the limit slide groove prevents the limit slider from continuing to move, thereby preventing the connecting rod 44 from continuing to move and preventing the connecting rod 44 from detaching from the fixed tube 45.

[0036] When this embodiment is used, the staff first holds the pull rod and moves the placement box 42 downward. The movement of the placement box 42 drives the connecting rod 44 to move inside the fixed tube 45. The movement of the connecting rod 44 drives the connecting spring 46 to stretch. When the placement box 42 is completely away from the fixed box 41, protective tools such as protective masks and protective gloves are taken from the inside of the placement box 42 on both sides of the partition plate 43, and then the pull rod is released. The connecting spring 46 loses the external force and returns to its original state, driving the connecting rod 44 to move, and then the placement box 42 can be driven to move into the fixed box 41. The staff then puts on the taken out protective masks and protective gloves and performs subsequent painting operations. This is convenient and can remind the staff to wear protective tools to avoid the paint contacting the staff's hand skin and breathing the odor of the paint during the subsequent painting operation, causing damage to the staff's physical and mental health.

[0037] The structure and principle of the drying mechanism 5 composed of a shift block, a shift bar, a piston plate, a spring, an air jet groove, and an air groove in the utility model have been disclosed in a construction steel structure painting device disclosed in Chinese patent application number 202121825388.0. Its working principle is: an air groove is opened inside the box body 1, a one-way valve is fixedly connected to one end of the air groove, a spring is connected inside the air groove, one end of the spring is connected to a piston plate, a shift bar is connected to the side wall of the piston plate, a shift block is arranged on the rotating fixing mechanism 6 and at the position corresponding to the shift bar, and the side wall of the air groove A plurality of air jet slots are arranged on and inside the box body 1. When in use, when the rotating fixing mechanism 6 rotates, the shifting block reciprocates the shifting bar, thereby pushing the piston plate against the inner wall of the box body 1 through the shifting bar to squeeze the internal air through the air jet slot to perform all-round drying and air jetting on the building steel structure. At the same time, when the shifting block is separated from the shifting bar, the piston plate rebounds due to the spring rebound force, allowing the air to enter one side of the piston plate through the one-way valve inside the air slot, thereby allowing the building steel structure to be dried in real time while rotating and spraying paint in all directions by reciprocating the shifting bar.

[0038] The structure and principle of the rotating fixing mechanism 6 composed of a motor, a rotating rod A, a small spring, a pressure plate, a threaded rod handle, an internally threaded sleeve, a connecting block, an elastic plate, a push block, a plane bearing, and a fixed frame in the utility model have been disclosed in a building steel structure painting device disclosed in Chinese patent application No. 202121825388.0. Its working principle is: a fixed frame is connected to the inner wall of the box body 1, and a motor is connected to the inside of the fixed frame. One end of the motor is fixedly connected to one end of the rotating rod A, and the other end of the rotating rod A passes through the fixed frame and is fixedly connected to one end of the small spring. The outer wall of the rotating rod A is fixed to the fixed frame. The inner wall of the fixed frame is rotatably connected through a bearing, the other end of the small spring is fixedly connected to one side of the inner wall of the pressure plate, the outer wall of the rotating rod A is slidably connected to the inner wall of the pressure plate, and a threaded rod turning handle is provided on the side wall of the box body 1 and at the position corresponding to the fixed frame. One end of the threaded rod turning handle passes through one side of the box body 1 and is rotatably connected to the inner wall of the box body 1 through a bearing, the outer wall of the threaded rod turning handle is threadedly connected to the inner wall of the internal threaded sleeve, the top of the internal threaded sleeve is slidably connected to the inner wall of the box body 1, one end of the internal threaded sleeve is fixedly connected to the outer wall of the connecting block, one side of the connecting block is fixedly connected to one end of the elastic plate, the other end of the elastic plate is fixedly connected to one side of the push block, and the other end of the push block is fixedly connected to one side of the push block. One side is fixedly connected with one side of the plane bearing. When in use, the building steel structure that needs to be painted is placed inside the box body 1, and then the threaded rod handle is turned to connect with the inner wall of the internal threaded sleeve and drive the internal threaded sleeve to slide to the right on the inner wall of the box body 1, so that the internal threaded sleeve pushes the connecting block to push the push block through the deformation of the elastic plate to drive the plane bearing to contact and press one side of the building steel structure, and then the elastic plate is deformed to clamp it while buffering it. At the same time, the left and right sides of the plane bearing can rotate independently through the internal ball bearings, thereby When the pressure plate is clamped, the small spring is deformed and presses the rotating rod A, thereby firmly clamping the building steel structure and buffering it through the elastic plate and the small spring, thereby preventing the outer wall of the building steel structure from being damaged when the clamping is too tight. The motor is started to drive the rotating rod A to rotate. The small spring is a square rotating rod, so it can slide with the inner wall of the pressure plate while driving the pressure plate to rotate, and at the same time drive the building steel structure to rotate on the right side of the plane bearing, so that the building steel structure can rotate inside the box 1 while keeping the building steel structure in all directions to be atomized and sprayed by the paint pipe 2.

[0039] The working principle and use process of the utility model are as follows: the staff of the utility model first holds the pull rod and moves the placement box 42 downward, and the movement of the placement box 42 drives the connecting rod 44 to move inside the fixed tube 45, and the movement of the connecting rod 44 drives the connecting spring 46 to stretch. When the placement box 42 is completely away from the fixed box 41, protective tools such as protective masks and protective gloves are taken from the placement box 42 on both sides of the partition plate 43, and then the pull rod is released, and the connecting spring 46 loses the external force and returns to its original state, driving the connecting rod 44 to move, and then the placement box 42 can be driven to move and be stored in the fixed box 41. , the staff then puts on the protective mask and protective gloves taken out, and then carries out the subsequent painting operation, which is convenient and can remind the staff to wear protective tools to avoid the paint contacting the staff's hand skin and breathing the odor of the paint during the subsequent painting operation, causing damage to the staff's physical and mental health. Then open the box door 3, align the positioning groove 71 with the position of the positioning protrusion 72, and then move the receiving box 73 into the box body 1. With the cooperation of the positioning protrusion 72 and the positioning groove 71, a guiding effect can be provided for the moving insertion of the receiving box 73. When the receiving box 73 is fully inserted into the box body 1, and then rotate the rotating screw 76 to rotate and move along the fixing block 75. The movement of the rotating screw 76 drives the pressing block 74 to move and the restoring spring 77 to stretch. When the pressing block 74 completely enters the pressing groove 78, the rotation of the rotating screw 76 is stopped. Under the action of the pressing block 74, the receiving box 73 can be pressed and fixed. Then, the building steel structure to be painted is placed inside the box body 1, and the rotating fixing mechanism 6 is used to fix the building steel structure, and then the box door 3 is closed. Then, the paint spraying pipe 2 is connected to the external paint source, and the paint spraying pipe 2 is used to spray the external paint. When the paint is applied to the steel structure, excess paint on the steel structure falls under gravity into the receiving box 73 for collection, preventing the paint from dripping into the box 1, thereby polluting the internal environment of the box 1 and wasting the paint. When the paint is applied to one end of the paint spraying pipe 2, the rotating fixing mechanism 6 is used to drive the steel material to rotate, so as to facilitate the subsequent painting operation on the other end of the steel material. In the process of using the rotating fixing mechanism 6 to drive the steel material to rotate, the drying mechanism 5 can dry the sprayed paint.
