It can grip these materials through power drive and can tilt forward and backward at a certain angle to facilitate the dumping and transfer of materials.

[0003] Chinese Patent discloses a waste fork (authorized announcement number CN206529217U). When this patented technology is used, the lifting part is pulled upward, and under the action of gravity, the first fork rod and the second fork rod automatically cooperate to work. Therefore, the loading and unloading of waste can be completed without additional external force, which improves work efficiency. Moreover, no additional manual operation is required, so the situation of operators being scratched will not occur, and manpower is also saved.

[0004] In view of the above and related existing technologies, the inventor believes that the following defects often exist: The length of the traditional waste fork is fixed, making it difficult to adapt to the handling requirements of goods of different sizes. When faced with diverse goods sizes, operators often need to replace forks of different lengths, which reduces the work efficiency of the staff and affects the applicable range of the waste fork. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is: There is a disadvantage in the prior art that the waste fork is not convenient to adjust the length. For this reason, we propose a telescopic waste fork for a forklift.

[0006] In order to achieve the above purpose, the present application adopts the following technical solution: A telescopic waste fork for a forklift, including a mounting plate, an arc-shaped clamp and a support plate are installed at the front end of the mounting plate, a plurality of parallel clamps are installed at the front end of the support plate, a telescopic chuck is slidably connected inside the parallel clamp, a pressing groove is opened on one side of the telescopic chuck, a elastic spring is installed inside the pressing groove, a plurality of elastic outlets are opened on one side of the parallel clamp, one side of the elastic spring is fixedly connected with a pressing block, the elastic outlet is slidably connected with the pressing block inside, and the pressing groove is slidably connected with the pressing block inside.

[0007] Preferably, first chutes are opened at both the top and bottom inside the parallel clamp, first sliders are fixed at both the top and bottom of the telescopic chuck, and the first sliders are slidably connected with the inside of the first chutes.

[0008] Preferably, second chutes are opened at both the front end and the rear end inside the pressing groove, second sliders are fixed at both the front end and the rear end of the pressing block, and the second sliders are slidably connected with the inside of the second chutes.

[0009] Preferably, a reset spring is fixedly connected to the rear end of the telescopic chuck, and one end of the reset spring close to the support plate is fixedly connected to the inside of the parallel clamp.

[0010] Preferably, a rounded corner is formed on the surface of the pressing block, and the size of the rounded corner is adapted to the ejection port.

[0011] Preferably, a friction plate is installed at the top of the parallel clamp.

[0012] Preferably, the parallel clamp and the telescopic chuck are made of high-strength alloy material.

[0013] Technical effects and advantages of the present utility model:

[0014] By pressing the pressing block inward to store the elastic force of the elastic spring in the present utility model, the limit of the telescopic chuck is released. At this time, the telescopic chuck is pulled out from the parallel clamp. When it is pulled out to a position suitable for clamping the waste material, the pressing block is aligned with the ejection port, and the elastic force stored in the elastic spring drives the pressing block to eject, so that the telescopic chuck is limited, thereby achieving convenient adjustment when the length of the parallel clamp needs to be adjusted and improving the application range of the device.

Detailed implementation manners

[0021] Now, the present utility model will be further described in detail with reference to the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] Referring to Figures 1 - 3 as shown, the utility model provides a technical solution: a telescopic waste fork for a forklift, which includes a mounting plate 1. An arc-shaped clamp 2 and a support plate 3 are installed at the front end of the mounting plate 1. A plurality of parallel clamps 4 are installed at the front end of the support plate 3. A telescopic chuck 5 is slidably connected inside the parallel clamp 4. A pressing groove 6 is formed on one side of the telescopic chuck 5. A resilient spring 7 is installed inside the pressing groove 6. A plurality of elastic outlets 8 are formed on one side of the parallel clamp 4. One side of the resilient spring 7 is fixedly connected to a pressing block 9. The pressing block 9 is slidably connected inside the elastic outlet 8, and the pressing block 9 is slidably connected inside the pressing groove 6. By pressing the pressing block 9 inward to store energy in the resilient spring 7, the limit of the telescopic chuck 5 is released. At this time, the telescopic chuck 5 is pulled out from the parallel clamp 4. When it is pulled out to a position suitable for clamping waste, the pressing block 9 is aligned with the elastic outlet 8, and the elastic force stored in the resilient spring 7 drives the pressing block 9 to pop out, so that the telescopic chuck 5 is limited, thus achieving convenient adjustment when the length of the parallel clamp 4 needs to be adjusted and improving the applicable range of the device.

[0023] Referring to Figure 3 as shown, in this embodiment: first chutes 10 are formed at both the top and bottom inside the parallel clamp 4. First sliders 11 are fixed at both the top and bottom of the telescopic chuck 5. The first sliders 11 are slidably connected inside the first chutes 10. Through the arrangement of the first chutes 10 and the first sliders 11, a stable guiding effect can be formed during the process of pulling out the telescopic chuck 5, preventing the telescopic chuck 5 from shifting and causing the pressing block 9 to fail to pop into the elastic outlet 8, affecting the fixation of the telescopic chuck 5 after adjustment.

[0024] Referring to Figure 4 as shown, in this embodiment: second chutes 12 are formed at both the front end and the rear end inside the pressing groove 6. Second sliders 13 are fixed at both the front end and the rear end of the pressing block 9. The second sliders 13 are slidably connected inside the second chutes 12. Through the arrangement of the second chutes 12 and the second sliders 13, a stable limit can be formed during the process of the pressing block 9 popping out, preventing the pressing block 9 from popping out too much due to the elastic force of the resilient spring 7 and causing it to fall off, affecting the use experience.

[0025] Referring to Figure 4 as shown, in this embodiment: a return spring 14 is fixedly connected to the rear end of the telescopic chuck 5. One end of the return spring 14 close to the support plate 3 is fixedly connected to the inside of the parallel clamp 4. Through the arrangement of the return spring 14, when the limit of the telescopic chuck 5 is released, the pulling force stored in the return spring 14 is released to drive the telescopic chuck 5 to quickly pop out, so that the telescopic chuck 5 quickly releases the limit, improving the adjustment efficiency.

[0026] Referring to Figure 4As shown in the figure, in this embodiment: a rounded corner 15 is provided on the surface of the pressing block 9, and the size of the rounded corner 15 is adapted to the ejection port 8. Through the setting of the rounded corner 15, when the telescopic chuck 5 needs to be retracted, the telescopic chuck 5 is pushed inward, and the edge of the rounded corner 15 slides inside the ejection port 8, so that the pressing block 9 slides into the pressing groove 6, so that when the staff retracts the telescopic chuck 5, the telescopic chuck 5 can be released from the limit without continuously pressing the pressing block 9.

[0027] Refer to Figure 5 As shown in the figure, in this embodiment: a friction plate 16 is installed at the top of the parallel clamp 4.

[0029] When the clamp 5 is pulled out to a position suitable for clamping the waste material, the pressing block 9 is aligned with the ejection outlet 8, and the elastic force stored in the elastic spring 7 drives the pressing block 9 to eject, so that the telescopic clamp 5 is limited, thereby achieving convenient adjustment when the length of the parallel clamp 4 needs to be adjusted, and the applicable scope of the lifting device is improved. Through the arrangement of the first slide groove 10 and the first slide block 11, the telescopic clamp 5 can form a stable guiding effect during the pulling process, and the telescopic clamp 5 can be prevented from being offset and causing the pressing block 9 to be unable to eject into the ejection outlet 8, affecting the fixation of the telescopic clamp 5 after adjustment. Through the arrangement of the second slide groove 12 and the second slide block 13, the pressing block 9 can be firmly limited during the ejection process, and the elastic force of the elastic spring 7 can be prevented from causing the pressing block 9 to eject too much and fall off, affecting the use Through user experience, through the setting of the reset spring 14, when the telescopic clamp 5 is released from the limit, the tension stored in the reset spring 14 is released to drive the telescopic clamp 5 to pop out quickly, so that the telescopic clamp 5 is quickly released from the limit, improving the adjustment efficiency. Through the setting of the fillet 15, when the telescopic clamp 5 needs to be retracted, the telescopic clamp 5 is pushed inwardly, and the edge of the fillet 15 slides with the inside of the ejection outlet 8, so that the pressing block 9 slides into the pressing groove 6, so that the staff can achieve the effect of releasing the limit of the telescopic clamp 5 without continuously pressing the pressing block 9 during the process of retracting the telescopic clamp 5. Through the setting of the friction plate 16, the parallel clamp 4 and the telescopic clamp 5 can have greater friction when contacting the waste, making its grip more stable. Through the setting of this material, the parallel clamp 4 and the telescopic clamp 5 can have better pressure resistance and wear resistance when gripping heavy objects, effectively improving its service life.
