Description

Technical Field

[0001] This utility model relates to the field of limiting structure technology, and in particular to a limiting structure for a roll of material for cutting and punching holes in a refrigerator side panel. Background Technology

[0002] In refrigerator manufacturing, the cutting and punching of side and back panels is a crucial step in the production process. Traditionally, the positioning and limiting of the material roll in this process relies primarily on simple clamps or brackets. However, these limiting methods present several technical problems. Firstly, traditional limiting methods often lack sufficient flexibility and adjustability. Since different batches or models of refrigerator side and back panels may require material rolls of different sizes and types, the limiting methods often struggle to accommodate this diversity. This leads to the material roll easily shifting or wobbling during the cutting and punching process, affecting processing accuracy and efficiency. Secondly, the limiting methods also suffer from instability and reliability. Due to the lack of effective guiding and limiting mechanisms, the positioning plate may become unstable or move excessively during movement. This can not only cause damage to the material roll or processing errors but also potentially damage production equipment, increasing production costs and risks.

[0003] Therefore, in order to address this problem, this utility model provides a material roll limiting structure for cutting and punching holes in the side panel of a refrigerator. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a material roll limiting structure for cutting and punching the side panel of a refrigerator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material roll limiting structure for cutting and punching holes in a refrigerator side panel, comprising an outer U-shaped frame, an inner U-shaped frame rotatably connected to the inside of the outer U-shaped frame via a rotating shaft, three adjusting seats equally spaced on one side of the outer U-shaped frame, an adjusting threaded rod between the inner U-shaped frame and the adjusting seats, a side seat on the side of the outer U-shaped frame away from the inner U-shaped frame, a mounting bracket symmetrically and movably connected inside the side seat, a fixing threaded rod threaded between the side seat and the mounting bracket, locking threaded rods symmetrically arranged on both sides of the inner U-shaped frame, and a positioning plate fixedly connected to one end of the locking threaded rod passing through the inner U-shaped frame.

[0006] Preferably, the surface of the side seat is symmetrically provided with threaded grooves, and the threaded grooves are movably connected to the fixed threaded rod.

[0007] Preferably, the mounting bracket has a plurality of mounting holes at equal intervals on the side away from the outer U-shaped bracket, and the mounting holes are used for installation.

[0008] Preferably, a tightening seat is fixedly connected to the end of the locking threaded rod away from the positioning plate, and there is a distance between the outer U-shaped frame and the locking threaded rod.

[0009] Preferably, a limiting rod is provided on the side of the positioning plate, the limiting rod is slidably connected to the inner U-shaped frame, and a limiting seat is provided at one end of the limiting rod.

[0010] Compared with the prior art, this utility model provides a material roll limiting structure for cutting and punching holes in the side panel of a refrigerator, which has the following beneficial effects:

[0011] 1. The material roll limiting structure for cutting and punching holes in the refrigerator side panel achieves high flexibility and adjustability through the design of adjusting and fixing threaded rods. Users can easily adjust the position of the inner U-shaped frame by rotating the adjusting threaded rod to accommodate material rolls of different sizes and types according to actual needs. At the same time, the introduction of the fixing threaded rod makes the mounting bracket more stable and reliable, ensuring that the material roll will not shift or shake during the cutting and punching process, thereby improving processing accuracy and efficiency.

[0012] 2. The material roll limiting structure for cutting and punching holes in the refrigerator side panel, through the sliding connection between the limiting rod and the inner U-shaped frame and the design of the limiting seat, provides stable guidance and limiting function for the movement of the positioning plate. This not only ensures the stability and accuracy of the positioning plate during movement, but also avoids damage to the material roll or processing errors caused by excessive movement of the positioning plate.

Therefore, they should not be construed as limitations on this utility model.

[0020] Reference Figures 1-4 A limiting structure for cutting and punching material rolls for refrigerator side panels mainly includes an outer U-shaped frame 1. Inside the outer U-shaped frame 1 is an inner U-shaped frame 2, which are rotatably connected by a pivot, allowing the inner U-shaped frame 2 to be adjusted relative to the outer U-shaped frame 1. Three adjusting seats 3 are installed at equal intervals on one side of the outer U-shaped frame 1 to assist in adjusting the position of the inner U-shaped frame 2. Adjusting threaded rods 4 are provided between the inner U-shaped frame 2 and these adjusting seats 3; rotating the adjusting threaded rods 4 allows for precise position adjustment of the inner U-shaped frame 2 relative to the outer U-shaped frame 1. Furthermore, a side seat 5 is provided on the side of the outer U-shaped frame 1 away from the inner U-shaped frame 2. Two mounting brackets 6 are symmetrically and movably connected inside the side seat 5 for installing or fixing other components. A fixing threaded rod 7 is threaded between the side seat 5 and the mounting brackets 6; rotating the fixing threaded rod 7 secures the mounting brackets 6. The inner U-shaped frame 2 is symmetrically provided with locking threaded rods 8 on both sides. A positioning plate 9 is fixedly connected to one end of the locking threaded rod 8 that passes through the inner U-shaped frame 2, which is used to limit the material roll. Through the above structure, the material roll for cutting and punching the refrigerator side panel is effectively limited, while providing a flexible position adjustment function.

[0021] On the surface of the side seat 5, two threaded grooves 501 are symmetrically arranged, which are movably connected to the fixed threaded rod 7. When it is necessary to fix the mounting bracket 6, the fixed threaded rod 7 is passed through the mounting bracket 6 and screwed into the threaded groove 501. The mounting bracket 6 is tightened by rotating the fixed threaded rod 7. The engagement between the threaded groove 501 and the fixed threaded rod 7 achieves a stable fixation of the mounting bracket 6.

[0022] On the side of the mounting bracket 6 away from the outer U-shaped frame 1, several mounting holes 601 are provided at equal intervals. These mounting holes 601 can be used to install other components or accessories, such as hooks, brackets, etc., to meet different usage needs. By providing multiple mounting holes 601, the versatility and practicality of the mounting bracket 6 are increased.

[0023] The locking threaded rod 8 has a tightening seat 11 fixedly connected to the end away from the positioning plate 9, which facilitates the user's rotation of the locking threaded rod 8. Meanwhile, a certain distance exists between the outer U-shaped frame 1 and the locking threaded rod 8 to ensure that the locking threaded rod 8 does not interfere with the outer U-shaped frame 1 during rotation. The design of the tightening seat 11 improves the ease of operation of the locking threaded rod 8; at the same time, the gap between the locking threaded rod 8 and the outer U-shaped frame 1 avoids interference problems.

[0024] The positioning plate 9 has a limiting rod 10 on its side, which is slidably connected to the inner U-shaped frame 2 to ensure the stability of the positioning plate 9 during movement. A limiting seat 1001 is provided at one end of the limiting rod 10 to limit its sliding range. Through the sliding connection between the limiting rod 10 and the inner U-shaped frame 2, and the design of the limiting seat 1001, the stable movement and limiting function of the positioning plate 9 are achieved.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
