Description

Technical Field

[0001] The utility model relates to the technical field of garbage bin welding and positioning, in particular to a garbage bin main body structure welding device. Background Art

[0002] A trash bin, also known as a waste bin or garbage can, is a place where garbage is stored. Most are made of metal or plastic. Plastic bags are placed inside, and when the garbage is full, the bags are tied up and thrown away. Trash bins are a reservoir for daily filth and a reflection of social culture. Currently, to make trash bins more durable, they require assembly, welding, and spray coating using materials such as iron. During this welding process, proper positioning of the bin is crucial.

[0003] The existing announcement number is CN107398669A, which is a welding tool for the rear frame of a garbage bin. This patent uses a molding groove and several welding clamps to perform pressing, replacing traditional hammering, knocking, repair welding and shaping processes, greatly simplifying the process, shortening the production process, reducing the labor intensity of workers squatting and bending when hammering, eliminating the dent damage caused by hammering to the rear frame, ensuring the curvature of the two curved parts and their consistency requirements, and can effectively offset the welding deformation during square tube welding, thereby ensuring the curvature of the rear frame and the overall flatness requirements.

[0004] The inventor discovered in his daily work that the welding tooling for the rear frame of the trash can is provided with multiple positioning fixtures for the same position. The more clamping mechanisms there are, the more complicated the operation becomes and the more likely production errors are to occur. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] See also Figure 1-4 The utility model provides a technical solution: a welding device for the main structure of a garbage bin, comprising a base 1, a rotating column 2 is rotatably connected to the surface of the base 1, and a horizontal strip 3 is fixedly installed on the outer wall surface of the rotating column 2.

[0024] The specific configuration and function of the positioning device 4 and the limiting device 5 will be described in detail below.

[0025] In this embodiment: a positioning device 4 is provided on the surface of the horizontal strip board 3, and the positioning device 4 includes four support rods 41, and the four support rods 41 are fixedly installed on the surface of the horizontal strip board 3. The four support rods 41 are grouped into two and a hollow plate 42 is fixedly installed at one end away from the horizontal strip board 3, and the interior of the two hollow plates 42 are both slidably connected to two positioning plates 43.

[0026] In this embodiment, the setting of the positioning plate 43 has the effect of positioning the trash can.

[0027] Specifically, a U-shaped plate 44 is fixedly installed on the surface of the two hollow plates 42, and a threaded rod 45 is rotatably connected between the inner walls of the two ends of the U-shaped plate 44. A rotating wheel 46 is fixedly installed on the surface of the threaded rod 45, and the threads on the surface of the threaded rod 45 are reverse threads with the rotating wheel 46 as the center.

[0028] In this embodiment, the setting of the rotating wheel 46 has the effect of driving the threaded rod 45 to rotate.

[0029] Specifically, a vertical groove 47 is formed on the inner wall surface of the U-shaped plate 44, and two movable blocks 48 are threadedly connected to the surface of the threaded rod 45. A connecting rod 49 is fixedly installed between the movable blocks 48 and the positioning plate 43. The provision of the threaded rod 45 has the effect of driving the movable blocks 48 to move within the vertical groove 47, and the provision of the connecting rod 49 has the effect of driving the positioning plate 43 to move.

[0030] In this embodiment, a limiting device 5 is provided on the surface of the base 1. The limiting device 5 includes a vertical plate 501, which is fixedly mounted on the surface of the base 1. A sliding rod 502 is fixedly mounted on the surface of the vertical plate 501. A sliding plate 503 is slidably connected to the surface of the sliding rod 502. A limiting rod 504 is fixedly mounted on the surface of the sliding plate 503. A plurality of limiting holes 505 are provided in a circular shape on the outer wall surface of the rotating column 2. When the orientation of the trash bin needs to be adjusted during the welding process, the slider 510 is first slid so that the slider 510 moves on the surface of the vertical rod 509. The movement of the slider 510 on the surface of the vertical rod 509 drives the hinge plate 511 to move. The movement of the hinge plate 511 pulls the sliding plate 503 to move on the surface of the sliding rod 502. The movement of the sliding plate 503 on the surface of the sliding rod 502 drives the spring 507 to stretch. At the same time, the movement of the sliding plate 503 on the surface of the sliding rod 502 also drives the limiting rod 504 to move. The movement of the limiting rod 504 causes it to move from the limiting position. When the trash can is rotated to a suitable position, the slider 510 is released and the rebound force of the spring 507 is used to reinsert the limiting rod 504 into the corresponding limiting hole 505 to re-limit the rotation of the rotating column 2. Through the cooperation of the above structure, the horizontal strip 3 can be rotated, so that the position of the trash can can be easily adjusted during the welding process.

[0031] Specifically, a circular plate 506 is fixedly installed on the surface of one end of the sliding rod 502 away from the vertical plate 501 , and a spring 507 is fixedly installed between the circular plate 506 and the sliding plate 503 .

[0032] In this embodiment, the setting of the spring 507 has the effect of limiting the position of the sliding plate 503 on the surface of the sliding rod 502.

[0033] Specifically, a through groove 508 is provided on the surface of the vertical plate 501, and a vertical rod 509 is fixedly installed between the inner walls at both ends of the through groove 508. The surface of the vertical rod 509 is slidably connected to a slider 510, and the surface of the slider 510 is hinged to a hinge plate 511, and the hinge plate 511 is hinged to the sliding plate 503 at one end away from the slider 510.

[0034] In this embodiment, the hinge plate 511 is provided to drive the sliding plate 503 to move on the surface of the sliding rod 502 .

[0035] Working principle: By setting the positioning device 4, when the device needs to be used, the trash can is first placed on the surface of two positioning plates 43, and then the distance between the two positioning plates 43 is adjusted according to the size of the trash can. The rotating wheel 46 is first rotated, and the rotation of the rotating wheel 46 drives the threaded rod 45 to rotate. Since the threads on the surface of the threaded rod 45 are opposite threads with the rotating wheel 46 as the center, when the rotating wheel 46 drives the threaded rod 45 to rotate, the two movable plates threadedly connected on its surface will move toward each other inside the vertical groove 47. The two movable blocks 48 move toward each other inside the vertical groove 47 in the direction of approaching each other, driving the two connecting rods 49 to move toward each other. The two connecting rods 49 move in the direction of approaching each other, driving the two positioning plates 43 to move toward each other. The two positioning plates 43 move in the direction of approaching each other to clamp and position the trash can. Through the cooperation of the above structure, the purpose of positioning the trash can is achieved, so that the device has the characteristics of simple structure, fast and reliable positioning, and effectively improves welding efficiency. When the orientation of the trash can needs to be adjusted during the welding process, first slide the slider 510 to move the slider 510 on the surface of the vertical rod 509. The movement of the slider 510 on the surface of the vertical rod 509 will drive the hinge plate 511 to move. The movement of the hinge plate 511 pulls the sliding plate 503 to move on the surface of the slide rod 502. The movement of the sliding plate 503 on the surface of the slide rod 502 will drive the spring 507 to stretch. At the same time, the movement of the sliding plate 503 on the surface of the slide rod 502 also drives the limit rod 504 to move. The limit rod 504 moves so that it moves away from the limit rod 504. When the trash can is rotated to a suitable position, the slider 510 is released and the rebound force of the spring 507 is used to reinsert the limiting rod 504 into the corresponding limiting hole 505 to re-limit the rotation of the rotating column 2. Through the cooperation of the above structure, the horizontal strip 3 can be rotated, so that the position of the trash can can be easily adjusted during the welding process.
