Description

Technical Field

[0001] This utility model relates to the field of frame paper splicing and fixing frame technology, and in particular to an adjusting support device for frame paper splicing and fixing frame. Background Technology

[0002] In industries such as decoration, advertising, art production, and packaging, it is often necessary to splice multiple pieces of frame paper (or similar boards) together using internal or external fixed frames to form large two-dimensional or three-dimensional structures.

[0003] Existing methods for splicing and fixing frame paper often involve temporary fixation using simple clamps or manual support, followed by gluing or mechanical connection. This method has significant drawbacks: First, it relies on the operator's experience, making it difficult to ensure precise alignment and even stress distribution between multiple splicing points, which can easily lead to misalignment, warping, or unevenness in the spliced ​​frame. Second, the simple clamps have poor versatility and cannot adapt to the splicing needs of frame paper of different sizes and thicknesses, with each adjustment consuming a lot of time and resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing simple clamps, which have poor versatility and are difficult to adapt to frame papers of different sizes and thicknesses, and to provide an adjustable support device for splicing and fixing frame papers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjusting support device for splicing and fixing a frame of paper frame, comprising a base plate, a first knob on the outer surface of the base plate, a bidirectional lead screw fixedly connected to the outer surface of the first knob, a bearing fixedly connected to one end of the bidirectional lead screw, a movable frame sleeved on the outer surface of the bidirectional lead screw, an adjusting hole opened at one end of the movable frame, a movable plate sleeved on the inner wall of the movable frame, the movable plate slidably connected to the movable frame, a push plate sleeved on the inner wall of the movable plate, a fixing rod fixedly connected to the outer surface of the push plate, and the fixing rod slidably connected to the adjusting hole.

[0006] In a preferred embodiment, the outer surface of the movable frame is provided with a second knob, and a screw is fixedly connected to the outer surface of the second knob. The screw is threadedly connected to the movable frame, and a clamping plate is fixedly connected to one end of the screw.

[0007] In a preferred embodiment, a slide rod is fixedly connected to the outer surface of the clamping plate, a limit plate is fixedly connected to one end of the slide rod, and the outer surface of the slide rod is slidably connected to the inner wall of the movable frame.

[0008] In a preferred embodiment, the bearing is placed inside the base plate and is fixedly connected to the base plate.

[0009] In a preferred embodiment, the outer surface of the movable plate is provided with a sliding hole adapted to the fixed rod, and the sliding hole is slidably connected to the fixed rod.

[0010] In a preferred embodiment, the outer surface of the movable frame is provided with a screw hole adapted to the bidirectional lead screw, and the screw hole is threadedly connected to the bidirectional lead screw.

[0011] In a preferred embodiment, the outer surface of the base plate is provided with a sliding groove adapted to the movable frame, and the inner wall of the sliding groove is slidably connected to the outer surface of the movable frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention features a first knob, a bidirectional lead screw, and a movable frame. Rotating the first knob causes the bidirectional lead screw to rotate, which in turn drives the movable frame to slide on the base plate. This allows for easy adjustment of the movable frame's position according to the size of the frame paper, accommodating the splicing and fixing needs of frame papers of different sizes. A second knob, a screw, and a clamping plate are also included. Rotating the second knob causes the screw to move the clamping plate, clamping and fixing the frame paper to ensure its stability during splicing. A sliding rod and a limiting plate ensure the stability of the clamping plate's movement, preventing it from shifting during movement. The coordination of the movable plate, push plate, and fixing rod allows for fine-tuning of the frame paper's support by adjusting the position of the fixing rod within the adjustment hole, thereby improving splicing accuracy. This adjustable support device has a reasonable structural design, is easy to operate, and effectively improves the efficiency and quality of frame paper splicing and fixing. It solves the problems of inconvenience and insufficient stability in splicing and fixing frame papers of different sizes in existing technologies, possessing strong practicality and promotional value.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: an adjustable support device for splicing and fixing a frame of paper frame, including a base plate 1, a first knob 2 on the outer surface of the base plate 1, a bidirectional lead screw 4 fixedly connected to the outer surface of the first knob 2, a bearing 5 fixedly connected to one end of the bidirectional lead screw 4, the bearing 5 being placed inside the base plate 1 and fixedly connected to the base plate 1, a movable frame 3 sleeved on the outer surface of the bidirectional lead screw 4, and a screw hole adapted to the bidirectional lead screw 4 on the outer surface of the movable frame 3, the screw hole being threadedly connected to the bidirectional lead screw 4. The outer surface of the frame 1 is provided with a sliding groove that is adapted to the moving frame 3. The inner wall of the sliding groove is slidably connected to the outer surface of the moving frame 3. One end of the moving frame 3 is provided with an adjustment hole 14. The inner wall of the moving frame 3 is fitted with a moving plate 11, which is slidably connected to the moving frame 3. The inner wall of the moving plate 11 is fitted with a push plate 12. The outer surface of the push plate 12 is fixedly connected with a fixing rod 13. The outer surface of the moving plate 11 is provided with a sliding hole that is adapted to the fixing rod 13. The sliding hole is slidably connected to the fixing rod 13, and the fixing rod 13 is slidably connected to the adjustment hole 14.

[0023] In this embodiment, the base plate 1 provides a placement environment for the frame. By rotating the first knob 2, the bidirectional lead screw 4 rotates inside the bearing 5. Since the bidirectional lead screw 4 is threadedly connected to the movable frame 3, the movable frame 3 moves in opposite directions as the bidirectional lead screw 4 rotates. The movement of the movable frame 3 clamps frames of different specifications. After adjustment, the frame is placed inside the movable frame 3. Then, the movable plate 11 moves inside the movable frame 3 to clamp and limit the top of the frame, ensuring that the frame does not shake. When the movable plate 11 is in contact with the surface of the frame, the push plate 12 is pushed to move the fixing rod 13 inside the movable plate 11, so that the fixing rod 13 connects with the adjustment hole 14, thereby fixing the movable plate 11 and ensuring that the movable plate 11 will not fall off, thus fixing the top of the frame.

[0024] Example 2

[0025] like Figures 1-4 As shown, the outer surface of the movable frame 3 is provided with a second knob 6, and a screw 7 is fixedly connected to the outer surface of the second knob 6. The screw 7 is threadedly connected to the movable frame 3. One end of the screw 7 is fixedly connected to a clamping plate 8. The outer surface of the clamping plate 8 is fixedly connected to a slide rod 10. One end of the slide rod 10 is fixedly connected to a limit plate 9. The outer surface of the slide rod 10 is slidably connected to the inner wall of the movable frame 3.

[0026] In this embodiment, after the frame is fixed, the screw 7 is rotated inside the movable frame 3 by rotating the second knob 6. While the screw 7 is rotating, it also moves up and down. The movement of the screw 7 drives the clamping plate 8 to move. The movement of the clamping plate 8 makes the clamping plate 8 fit against the surface of the frame, thereby fixing the frame a second time. At the same time as the clamping plate 8 moves, the slide rod 10 also moves inside the movable frame 3, thereby guiding the clamping plate 8. Then, the limiting plate 9 ensures that the slide rod 10 will not separate from the movable frame 3, ensuring the normal progress of the fixing work.

[0027] Working principle:

[0028] like Figures 1-4As shown, in this utility model, the frame is first placed on the base plate 1. The first knob 2 is rotated, and the bidirectional lead screw 4 rotates under the support of the bearing 5. Due to the threaded engagement between the bidirectional lead screw 4 and the movable frame 3, and the sliding connection between the movable frame 3 and the sliding groove on the base plate 1, the movable frame 3 moves in opposite directions until it fits the frame's specifications and initially clamps its sides. Next, the movable plate 11 is moved to slide within the movable frame 3 until it is in contact with the top of the frame. Then, the push plate 12 is pushed, allowing the fixing rod 13 to slide within the sliding hole of the movable plate 11 and connect with the adjusting hole 14, thus fixing the movable plate 11 and limiting the top of the frame. Afterward, the second knob 6 is rotated, and the screw 7 rotates and moves up and down within the movable frame 3, driving the clamping plate 8 to move and make it fit against the frame surface for secondary fixing. During this process, the slide bar 10 slides within the moving frame 3 to guide the clamping plate 8, and the limiting plate 9 prevents the slide bar 10 from separating from the moving frame 3, ensuring that the entire adjustment and support device can stably and reliably adjust and support the frame paper splicing and fixing frame, effectively avoiding frame shaking and improving the accuracy and quality of splicing and fixing.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
