Description

Technical Field

[0001] This utility model relates to the field of non-powered telescopic machinery technology, and in particular to a non-powered telescopic machinery with flexible adjustable distance. Background Technology

[0002] A non-powered telescopic conveyor is a conveying device that can freely extend and retract in length. It is typically used for the fast and efficient transport of goods. Depending on different standards and requirements, non-powered telescopic conveyors can be classified in various ways. For example, according to the conveying direction, they can be divided into horizontal telescopic conveyors, inclined telescopic conveyors, and vertical telescopic conveyors; according to the type of conveyor belt, they can be divided into belt-type telescopic conveyors, roller-type telescopic conveyors, and chain-plate-type telescopic conveyors, etc.

[0003] Existing non-powered telescopic conveyors are not easy to quickly position the extension plate during the extension and retraction process, which reduces the stability of the non-powered telescopic conveyor. This may cause the goods to deviate from the predetermined position during the transportation process, affecting subsequent processing and sorting work. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art where the extension plate is not easily positioned quickly during use, thus reducing its stability. Therefore, this invention proposes a flexible adjustable non-powered telescopic machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flexible adjustable non-powered telescopic machine, comprising the present invention, which moves the telescopic cloth by pulling the extension plate, so that the other end of the telescopic cloth slides in the inner cavity of the positioning frame, thereby extending the telescopic machine. Furthermore, the extension plate can be positioned by the adjustment component, which not only allows for flexible adjustment but also enables efficient limiting of its position, thereby improving the stability of the telescopic machine in use.

[0007] To limit the position of the extension plate, preferably, the adjusting component includes: a button slidably connected within the extension plate, a rod fixedly connected to the button, a block fixedly connected to the end of the rod away from the button, a wedge slidably connected to the side of the block away from the rod, a positioning rod fixedly connected to the bottom of the wedge, one end of the positioning rod penetrating the extension plate and inserted into a perforated plate; a first spring disposed within the extension plate, both ends of the first spring being fixedly connected to the extension plate and the button respectively; and a second spring disposed at the bottom of the extension plate, both ends of the second spring being fixedly connected to the extension plate and the positioning rod respectively.

[0008] To facilitate the sliding of the extension plate, preferably, two sets of slide rails are fixedly connected inside the frame, and a slider that cooperates with the slide rails is fixedly connected to the bottom of the extension plate.

[0009] To improve the stability of the lateral movement of the extension plate, preferably, both sides of the extension plate are rotatably connected to guide wheels via pivot pins, and there are several guide wheels. The side of the guide wheel away from the extension plate is in contact with the frame.

[0010] To achieve the repositioning of the stretch fabric, preferably, a positioning frame is fixedly connected inside the frame, a positioning roller is slidably connected inside the positioning frame, and a tension spring is provided inside the positioning frame, with both ends of the tension spring fixedly connected to the positioning frame and the positioning roller, respectively.

[0011] To improve the stability of the stretch fabric movement, preferably, a driven roller is rotatably connected to the frame, and the driven roller is in contact with the stretch fabric.

[0012] Compared with the prior art, this utility model provides a flexible adjustable telescopic telescopic mechanism with the following advantages:

[0013] 1. This flexible adjustable non-powered telescopic machine, by setting an adjustment component, presses the button to make the insertion rod drive the insertion block to squeeze the inclined block. The inclined block, under pressure, drives the positioning rod to move upward and disengage from the inner cavity of the orifice plate. Then, the extension plate can be pulled to adjust. After adjusting to the specified position, the button is released. The positioning rod is reset by the cooperation of the first and second springs, so that it is inserted downward into the inner cavity of the orifice plate. This can efficiently position the telescopic machine, thereby improving its stability in use.

[0014] 2. This flexible adjustable non-powered telescopic machine, through the combination of a positioning frame and a tension spring, allows the extension plate to pull one end of the telescopic cloth when it moves, while the other end of the telescopic cloth drives the positioning roller to stretch the tension spring, thereby improving the stability of the telescopic cloth. Furthermore, after the extension plate is reset and inserted into the inner cavity of the frame, the tension spring can be used to reset the telescopic cloth.

[0015] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model moves the telescopic cloth by pulling the extension plate, so that the other end of the telescopic cloth slides in the inner cavity of the positioning frame, which can extend the telescopic machine. Furthermore, the extension plate can be positioned by using the adjusting parts, which not only allows for flexible adjustment but also enables efficient limiting, thereby improving the stability of the telescopic machine.

[0027] Example:

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A flexible adjustable non-powered telescopic machine includes a frame 1 and a perforated plate 4 fixedly installed in the frame 1. It also includes an extension plate 2, which is slidably connected to the inner cavity of the frame 1. A telescopic cloth 5 is fixedly connected to the extension plate 2. A positioning roller is fixedly connected to the end of the telescopic cloth 5 away from the extension plate 2. The positioning roller is slidably connected in the frame 1. An adjustment component 3 for positioning the extension plate 2 is provided on the extension plate 2.

[0029] Specifically, by pulling the extension plate 2, the telescopic cloth 5 is moved, and the other end of the telescopic cloth 5 slides in the inner cavity of the positioning frame 9, which can extend the telescopic machine. Furthermore, the extension plate 2 can be positioned by the adjusting component 3, which not only allows for flexible adjustment but also enables efficient limiting of its position, thereby improving the stability of the telescopic machine.

[0030] The adjusting component 3 includes a button 301, which is slidably connected to the extension plate 2. A rod 302 is fixedly connected to the button 301. A block 303 is fixedly connected to the end of the rod 302 away from the button 301. A wedge 304 is slidably connected to the side of the block 303 away from the rod 302. A positioning rod 305 is fixedly connected to the bottom of the wedge 304. One end of the positioning rod 305 passes through the extension plate 2 and is inserted into the perforated plate 4. A first spring 306 is provided in the extension plate 2, and both ends of the first spring 306 are fixedly connected to the extension plate 2 and the button 301, respectively. A second spring 307 is provided at the bottom of the extension plate 2, and both ends of the second spring 307 are fixedly connected to the extension plate 2 and the positioning rod 305, respectively.

[0031] Specifically, by setting the adjustment component 3 and pressing the button 301, the insertion rod 302 drives the insertion block 303 to press against the inclined block 304. The inclined block 304, under pressure, drives the positioning rod 305 to move upward and disengage from the inner cavity of the perforated plate 4. Then, the extension plate 2 can be pulled for adjustment. After adjustment to the specified position, the button 301 is released. The first spring 306 and the second spring 307 work together to reset the positioning rod 305, so that it is inserted downward into the inner cavity of the perforated plate 4. This enables efficient positioning of the telescopic machine, thereby improving its stability during use.

[0032] Two sets of slide rails 6 are fixedly connected inside the frame 1, and a slider 7 that works with the slide rails 6 is fixedly connected to the bottom of the extension plate 2. The slider 7 slides on the slide rails 6.

[0033] Specifically, by setting the slide rail 6 to cooperate with the slider 7, the extension plate 2 can move along the preset track, thereby improving its portability.

[0034] Both sides of the extension plate 2 are rotatably connected to guide wheels 8 via pivot pins. There are several guide wheels 8, and the side of the guide wheel 8 away from the extension plate 2 contacts the inner wall of the frame 1.

[0035] Specifically, by setting guide wheels 8, the extension plate 2 drives the guide wheels 8 to roll on the surface of the frame 1, which can improve the stability of its movement.

[0036] Positioning frames 9 are fixedly connected to both sides of the inner cavity of the frame 1. The positioning roller is slidably connected inside the positioning frame 9. A tension spring 10 is provided inside the positioning frame 9. The two ends of the tension spring 10 are fixedly connected to the positioning frame 9 and the positioning roller, respectively.

[0037] Specifically, by setting the positioning frame 9 and the tension spring 10 together, the extension plate 2 pulls one end of the telescopic cloth 5 to move when it moves, and the other end of the telescopic cloth 5 drives the positioning roller to stretch the tension spring 10, thereby improving the stability of the telescopic cloth 5. Furthermore, after the extension plate 2 is reset and inserted into the inner cavity of the frame 1, the tension spring 10 can be used to reset the telescopic cloth 5.

[0038] A driven roller is rotatably connected to the frame 1, and the surface of the driven roller is in contact with the inner side of the stretch fabric 5.

[0039] Specifically, by setting a driven roller, the stretch fabric 5 can be limited, thereby improving the stability of the stretch fabric 5 in use.

[0040] Working principle: During use, the operator presses button 301. As button 301 moves, it compresses the first spring 306, causing the insertion rod 302 to move. The insertion rod 302, in turn, causes the insertion block 303 to compress the inclined block 304. The inclined block 304, under pressure, moves the positioning rod 305 upwards. As the positioning rod 305 moves upwards, it compresses the second spring 307. Once the positioning rod 305 disengages from the inner cavity of the perforated plate 4, the limiting position on the extension plate 2 is released. At this point, the operator can adjust the position of the extension plate 2 by pulling it. During the movement, one end of the telescopic cloth 5 is pulled to move it, while the other end of the telescopic cloth 5 drives the transmission roller to stretch the tension spring 10. When the extension plate 2 moves to the designated position, the operator releases the button 301. At this time, the reaction force of the first spring 306 and the second spring 307 can reset the insertion rod 302 and the positioning rod 305, so that the positioning rod 305 is inserted downward into the perforated plate 4. Not only can pressing the button 301 adjust the flexibility of the extension plate 2, but releasing the button 301 can also effectively limit the extension plate 2, thereby improving its stability in use.

[0041] 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.
