[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0025] An auxiliary device for installing the bottom steel frame of a blister tray includes a mounting frame 1. A slidable L-shaped pull rod 2 is provided inside both ends of the mounting frame 1. The two L-shaped pull rods 2 are symmetrically arranged. An upper sleeve 3 is provided below the center of the mounting frame 1, and a lower sleeve 4 is provided below the upper sleeve 3. A rotating shaft 5 is fixedly installed at the center of the top of the upper sleeve 3 and the lower sleeve 4. The tops of the two rotating shafts 5 are rotatably installed at the bottom center of the mounting frame 1 and the bottom center of the upper sleeve 3 respectively. The lower sleeve 4 has the same structure and size as the upper sleeve 3. One side of the upper sleeve 3 is open, and a baffle 31 is hingedly installed at the top of the opening side by two symmetrically arranged hinges 32. The two sides of the end of the baffle 31 away from the hinge 32 are fixed to the upper sleeve 3 by two symmetrically arranged fixing bolts 33.
[0026] During use, the L-shaped pull rods 2 that slide out from the ends of the mounting frame 1 can be adjusted to accommodate different sizes of blister trays requiring installation, increasing the device's flexibility and applicability. The upper and lower sleeves 3 and 4, located below the center of the mounting frame 1, and the pivot 5 between them, allow for easy rotation and adjustment of the steel frame during installation, improving installation efficiency and accuracy. Furthermore, the opening on one side of the upper sleeve 3 and the hinged baffle 31 facilitate the insertion and securing of the steel frame, while securing bolts 33 ensure the frame's stability during installation.
[0027] As a preferred feature of this embodiment, two extrusion members 6 are fixedly mounted between the upper sleeve 3 and the mounting frame 1, and between the lower sleeve 4 and the upper sleeve 3. The length of the extrusion members 6 is adjustable. The two extrusion members 6 on the same sleeve are symmetrically located on either side of the rotating shaft 5. These extrusion members 6 connect the upper sleeve 3 to the mounting frame 1, and the lower sleeve 4 to the upper sleeve 3. After adjusting the angle between the upper and lower sleeves 3, 4, the angle can be fixed to prevent further angular deviation of the upper and lower sleeves 3, 4, during subsequent installation of the steel frame.
[0028] As a preferred embodiment of this embodiment, the extrusion member 6 includes a base 60, which is fixedly mounted on the top surface of the upper sleeve 3 and the top surface of the lower sleeve 4. The base 60 is internally threaded with a threaded shaft 62, and a screw head 63 is coaxially and integrally formed on the outer wall of the threaded shaft 62. The screw head 63 makes adjustment of the extrusion member 6 easier and faster. The user only needs to rotate the screw head 63 to achieve precise adjustment of the length of the extrusion member 6, which improves the convenience of operation.
[0029] As a preferred feature of this embodiment, a non-slip pad 61 is fixedly mounted on the top of the threaded shaft 62. The top of the non-slip pad 61 is equipped with anti-slip teeth. When the extrusion 6 is extended to its maximum length, its length is greater than the height of the rotating shaft 5. The multiple anti-slip teeth can respectively abut against the bottom surface of the mounting frame 1 and the bottom surface of the upper sleeve 3. This design increases the friction between the extrusion 6 and the corresponding bottom surface of the mounting frame 1 or the bottom surface of the upper sleeve 3, preventing the steel frame from rotating during installation and further ensuring the safety and stability of the installation. Furthermore, when the extrusion 6 is extended to its maximum length, its length is greater than the height of the rotating shaft 5, ensuring effective clamping of the steel frame.
[0030] As a preferred embodiment of this embodiment, two movable grooves 11 are respectively defined at both ends of the mounting frame 1, which slide with the crossbar ends of the two L-shaped tie rods 2. A screw 13 is rotatably mounted in the movable groove 11 via a bearing 14. The crossbar ends of the L-shaped tie rods 2 are inserted into the movable groove 11 and threadedly sleeved onto the outer sides of the screw 13. This design allows the extension length of the L-shaped tie rods 2 to be precisely adjusted by rotating the screw 13, thereby adapting to different sizes of blister trays requiring steel frame installation. The vertical ends of the two L-shaped tie rods 2 are clamped to the outer walls of the tray on both sides, improving the flexibility and applicability of the device.
[0031] As a preferred embodiment of this embodiment, a second bevel gear 16 is coaxially fixedly mounted on the end of the screw rod 13 near the bearing 14. A first bevel gear 15 is meshed with the second bevel gear 16. A drive shaft 100 is coaxially fixed to the first bevel gear 15. The top of the drive shaft 100 extends through the top outside of the mounting frame 1 and is coaxially and integrally connected to an adjustment knob 10. This design allows the user to rotate the screw rod 13 by rotating the adjustment knob 10, thereby adjusting the extension length of the L-shaped pull rod 2, achieving simple and quick operation.
[0032] As a preferred embodiment of this invention, a threaded hole 20 is formed on the inner side of the crossbar end of the L-shaped tie rod 2, which is threadedly connected to the screw rod 13. The L-shaped tie rod 2 never separates from the screw rod 13 during movement. This design ensures the stability and reliability of the L-shaped tie rod 2 when adjusting the length, and prevents the safety hazard caused by the L-shaped tie rod 2 separating from the screw rod 13.
[0033] As a preferred embodiment of the present invention, the adjusting knob 10 and the screw head 63 are both screw-shaped and have standard screw head sizes. This design allows the user to use standard tools to operate the adjusting knob 10 and the screw head 63, thereby improving the convenience and versatility of operation.
[0034] When the auxiliary device for installing the bottom steel frame of the blister tray of the utility model is in use:
[0035] The bottom of the blister tray in this embodiment is provided with an opening. When the steel frame is installed in the bottom opening of the blister tray, the bottom opening of the blister tray is placed upward.
[0036] Initial Preparation: Place the mounting aid above the bottom opening of the blister tray where the steel frame will be installed. Ensure that the mounting bracket 1 is stable, the L-shaped tie rod 2 is in its initial position, and the upper and lower sleeves 3 and 4 are not installed with the steel frame.
[0037] Adjust the length of the L-shaped tie rods 2: Depending on the width of the blister tray, rotate the adjustment knob 10 to rotate the screw 13. Since the screw 13 is threadedly connected to the crossbar end of the L-shaped tie rod 2, rotating the screw 13 causes the L-shaped tie rod 2 to move within the movable slot 11, thereby adjusting its extended length. When the distance between the vertical ends of the two L-shaped tie rods 2 is adjusted to match the width of the tray, stop rotating the adjustment knob 10, so that the vertical ends of the two L-shaped tie rods 2 are clamped to the outer walls of the tray.
[0038] Installing the steel frame: Insert the partial length of the steel frame into the opening of the upper casing 3 and secure it with fixing bolts 33 through the baffle 31. Rotate the shafts 5 at the top of the upper and lower casings 3 and 4 to adjust the angle of the steel frame to suit the installation requirements. During the adjustment process, the upper and lower casings 3 and 4 can rotate relative to each other to better position the steel frame.
[0039] Fixing the Steel Frame Angle: Once the steel frame angle is adjusted, adjust the length of the extrusion 6 by rotating the knob 63. As the extrusion 6 is extended, the anti-skid teeth on the anti-skid pad 61 firmly contact the adjacent sleeve or mounting bracket 1, thereby fixing the angle of the upper and lower sleeves 3 and 4 and preventing the steel frame from shifting during installation. The design of the anti-skid pad 61 and the anti-skid teeth increases friction, ensuring the stability of the steel frame.
[0040] Final Fixing and Inspection: Ensure that all L-shaped tie rods 2, extrusions 6, and fixing bolts 33 are adjusted and tightened. Then, install the steel frame on the inner wall of the pallet opening. Next, check that the steel frame is firmly seated within the bottom of the blister tray, without any wobble or shifting. If all is in order, the mounting aids can be removed, leaving the steel frame securely in place.
[0041] Reusable: When you need to install another steel frame, simply repeat the above steps. Due to its flexible design, the device can accommodate blister trays of varying sizes and shapes. Through the above working principle, this blister tray bottom steel frame installation auxiliary device can efficiently and accurately complete steel frame installation, improving installation efficiency and accuracy while ensuring safety and stability during the installation process.
