[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-2 A mobile safety pedal device for an injection molding machine includes a drive component 1, a guide rail 2, and a slider 3 slidably mounted on the guide rail 2. A pedal 4 is slidably mounted on the slider 3. The output end of the drive component 1 is connected to the slider 3. The injection molding machine includes a moving platen and a fixed platen. The drive component 1 provides power for the movement of the pedal 4, causing the pedal 4 to move between the moving platen and the fixed platen. The drive component 1, the guide rail 2, and the slider 3 are all disclosed in Chinese Patent Publication No. CN218053692U, entitled "A Mobile Safety Pedal Device for an Injection Molding Machine".

[0025] A rectangular groove is provided at the end of the pedal 4 away from the slider 3. An extension plate 5 is slidably installed in the rectangular groove. A strip hole connected to the rectangular groove is provided on the upper surface of the pedal 4. A moving block 6 is slidably installed in the strip hole. The moving block 6 is fixedly connected to the extension plate 5. A positioning strip 7 is fixedly installed on the pedal 4. Multiple positioning holes are provided on the positioning strip 7 at equal intervals. The positioning strip 7 is located directly above the strip hole. A positioning post 8 is installed on the moving block 6 through an elastic component. One end of the positioning post 8 is inserted into one of the positioning holes.

[0026] Reference Figures 4-6 Under the elastic force of the elastic component, one end of the positioning post 8 is stably inserted into the positioning hole, thereby restricting the movement of the moving block 6 within the strip hole. When the operator needs a larger standing area, one end of the positioning post 8 is removed from the positioning hole to release the lock on the moving block 6, causing the moving block 6 to move horizontally within the strip hole. As the moving block 6 moves, it will cause the extension plate 5 to move away from the slider 3 within the rectangular groove. The extension plate 5 extends from one end of the rectangular groove until it moves to the desired position. Then, one end of the positioning post 8 is inserted into another positioning hole to lock the moving block 6. The extension of the extension plate 5 can increase the usable area of ​​the pedal 4, which can adapt to different usage needs and operators, while improving the flexibility of the device and making it more reasonable and convenient to use.

[0027] The upper surface of the movable block 6 is provided with an installation groove. The elastic component includes a rectangular block 9 that is vertically slidably installed in the installation groove and a telescopic spring 10 that is fixedly installed in the installation groove. One end of the telescopic spring 10 is fixedly connected to the rectangular block 9. The side of the movable block 6 is provided with a rectangular hole that communicates with the installation groove. A connecting block 11 is vertically slidably installed in the rectangular hole. The connecting block 11 is fixedly connected to the rectangular block 9. A pressure plate 12 is fixedly installed at one end of the connecting block 11 that protrudes from the rectangular hole.

[0028] The positioning post 8 is mounted on the movable block 6 via the rectangular block 9. When locking is required, the operator can press the pressure plate 12 with their foot, which drives the rectangular block 9 to move vertically downward through the connecting block 11. The telescopic spring 10 is compressed, and the rectangular block 9 drives the positioning post 8 away from the positioning strip 7, thus releasing the lock. Then, the operator can push the movable block 6 with their foot to push out the extension plate 5. When locking is required again, the operator can remove their foot from the pressure plate 12. Under the elastic force of the telescopic spring 10, the rectangular block 9 drives the positioning post 8 to move vertically upward, inserting one end of the positioning post 8 into another positioning hole. When the extension plate 5 needs to be pushed, it can be pushed with the foot without bending over, making the operation more convenient.

[0029] A baffle 13 is fixedly installed at one end of the pedal 4. The baffle 13 extends along the axis of the guide rail 2 and is fixedly installed at one end of the pedal 4. The baffle 13 can prevent the operator from stepping off the pedal 4 and the extension plate 5, thereby improving the safety of the device during use.

[0030] Reference Figure 3 The bottom of the pedal 4 has symmetrical limit holes, and support rods 14 are horizontally slidably inserted into the two limit holes. One end of each support rod 14 is fixedly connected to the bottom of the extension plate 5 through the mounting block 15. When the extension plate 5 moves on the pedal 4, it will drive the two support rods 14 to move at the same time. The support rods 14 can support the extension plate 5 and ensure that the extension plate 5 can support a heavier weight.

[0031] An anti-slip pad is fixedly installed on the upper surface of pedal 4. The anti-slip pad is made of rubber. The anti-slip pad can increase the friction of the pedal 4 surface and prevent the operator from slipping on pedal 4.

[0032] In this invention, under the elastic force of the elastic component, one end of the positioning post 8 is stably inserted into the positioning hole, thereby restricting the movement of the moving block 6 within the strip hole. When the operator needs a larger standing area, one end of the positioning post 8 is removed from the positioning hole to release the lock on the moving block 6, causing the moving block 6 to move horizontally within the strip hole. As the moving block 6 moves, it will cause the extension plate 5 to move away from the slider 3 within the rectangular groove. The extension plate 5 extends from one end of the rectangular groove until it reaches the desired position. Then, one end of the positioning post 8 is inserted into another positioning hole to lock the moving block 6. The extension of the extension plate 5 increases the usable area of ​​the pedal 4, which can adapt to different usage needs and operators, while improving the flexibility of the device and making it more reasonable and convenient to use.

[0033] 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.
