Description

Technical Field

[0001] This utility model relates to the field of material trolley technology, and in particular to a foldable and retractable material trolley for wafer production workshops. Background Technology

[0002] In wafer fabrication workshops, material trolleys are used to transfer wafers, reducing the distance and time for manual handling and improving production efficiency.

[0003] However, existing technologies have some problems: existing material carts cannot be folded and stored. Traditional material carts can only be simply covered by the handle, but the overall length is still too long. The cart body cannot be folded and stored, which takes up a lot of space and is inconvenient for people to use. Therefore, it is necessary to provide a foldable material cart for wafer production workshops to solve the above technical problems. Utility Model Content

[0004] This utility model provides a foldable and storable material trolley for wafer fabrication workshops, which solves the technical problems of existing material trolleys that cannot be folded and stored, and traditional material trolleys that can only be simply covered by the handle, but are still too long overall, cannot be folded and stored, take up a lot of space, and are inconvenient for people to use.

[0005] To solve the above-mentioned technical problems, this utility model provides a foldable and retractable material trolley for wafer fabrication workshops, comprising:

[0006] A first support plate has an L-shaped slide rail fixedly connected to the left side of the front side and the left side of the rear side of the first support plate. A slide column is slidably connected inside the L-shaped slide rail. A second support plate is fixedly connected to one side of the slide column. A concave seat is fixedly connected to the front and rear sides of the upper right side of the first support plate. A handrail is rotatably connected inside the concave seat through a pin. The length of the first support plate is greater than the length of the second support plate.

[0007] A locking assembly is located on an L-shaped slide rail and is used to clamp and fix the slide column.

[0008] Preferably, the locking assembly includes a threaded hole, the threaded hole is internally threaded with a lead screw, one end of the lead screw is fixedly connected to a knob, and the other end of the lead screw abuts against the surface of a slide column.

[0009] Preferably, the first support plate has positioning grooves on both the front and rear sides of its left side, and a positioning block is inserted into the positioning groove. One end of the positioning block is fixedly connected to the right side of the second support plate.

[0010] Preferably, the front and rear sides of the lower right side of the first support plate and the front and rear sides of the lower left side of the second support plate are fixedly connected to casters, and the surfaces of the casters are provided with anti-slip patterns.

[0011] Preferably, the surface of the handrail is covered with a handle sleeve, and the handle sleeve is made of elastic material.

[0012] Preferably, the interior of the concave seat is fixedly connected to the handrail by a wing screw, and both the handrail and the concave seat have through holes adapted to the wing screw.

[0013] Compared with related technologies, the foldable and retractable material trolley for wafer fabrication workshops provided by this utility model has the following advantages:

[0014] This utility model provides a foldable and retractable material trolley for wafer manufacturing workshops. Through the precise cooperation of the sliding column and the L-shaped slide rail (gap 0.01-0.03mm), the second support plate has low pulling resistance, making it easy to fold and unfold.

[0015] This utility model provides a foldable and retractable material trolley for wafer manufacturing workshops. Through the cooperation of positioning grooves and positioning blocks, it ensures that the flatness of the first and second support plates is without deviation after unfolding, and guarantees the load-bearing capacity of the first and second support plates, preventing poor load-bearing capacity.

[0016] This utility model provides a foldable and retractable material trolley for wafer manufacturing workshops. The locking component locks and secures the sliding column during use, preventing displacement of the sliding column on the L-shaped slide rail and preventing loosening when the first and second support plates are unfolded.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1:

[0024] Please see Figure 1-4 This utility model provides a technical solution: a foldable and retractable material trolley for wafer manufacturing workshops, comprising: a first support plate 1, with L-shaped slide rails 2 fixedly connected to the left side of the front side and the left side of the rear side of the first support plate 1, a sliding column 3 slidably connected inside the L-shaped slide rail 2, a second support plate 4 fixedly connected to one side of the sliding column 3, a concave seat 5 fixedly connected to the front and rear sides of the upper right side of the first support plate 1, a handrail 6 rotatably connected inside the concave seat 5 via a pin 13, the length of the first support plate 1 being greater than the length of the second support plate 4, and a locking assembly 7 located on the L-shaped slide rail 2, the locking assembly 7 being used to abut and fix the sliding column 3.

[0025] In this embodiment, when folding, loosen the knob 73 to move the lead screw 72 out along the threaded hole 71 and disengage the lead screw 72 from the surface of the slide column 3, release the constraint of the slide column 3, and pull the second bearing plate 4 outward. The second bearing plate 4 slides along the L-shaped slide rail 2 through the slide column 3 and makes the slide column 3 slide to the top of the L-shaped slide rail 2.

[0026] Example 2:

[0027] Please see Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: the locking assembly 7 includes a threaded hole 71, a lead screw 72 is threadedly connected inside the threaded hole 71, a knob 73 is fixedly connected to one end of the lead screw 72, and the other end of the lead screw 72 abuts against the surface of the sliding column 3. The front and rear sides of the left side of the first bearing plate 1 are provided with positioning grooves 8, and positioning blocks 9 are inserted into the positioning grooves 8. One end of the positioning block 9 is fixedly connected to the right side of the second bearing plate 4. The front and rear sides of the lower right side of the first bearing plate 1 and the front and rear sides of the lower left side of the second bearing plate 4 are fixedly connected with universal wheels 10.

The interior of the concave seat 5 is fixedly connected to the handrail 6 through a wing screw 11. Both the handrail 6 and the concave seat 5 are provided with through holes 12 that are adapted to the wing screw 11.

[0028] In this embodiment: At this time, the positioning block 9 is pulled out from the positioning groove 8, and then the second support plate 4 is flipped upward. When the second support plate 4 is completely retracted and overlapped above the first support plate 1, the wing screw 11 is loosened at the same time. Then the handrail 6 is rotated through the pin 13 to be parallel above the first support plate 1 to complete the folding. When unfolding, the assembly can be completed by performing the reverse operation according to the above steps.

[0031] Step 1: When folding, loosen the knob 73 to move the lead screw 72 out along the threaded hole 71 and disengage the lead screw 72 from the surface of the slide column 3, release the constraint of the slide column 3, and pull the second bearing plate 4 outward;

[0032] Step 2: The second bearing plate 4 slides along the L-shaped slide rail 2 via the sliding column 3, and the sliding column 3 slides to the top of the L-shaped slide rail 2.

[0033] Implementation steps for the second innovation point:

[0034] Step 1: At this time, the positioning block 9 is pulled out from the positioning groove 8, and then the second bearing plate 4 is flipped upward. When the second bearing plate 4 is completely retracted and overlapped above the first bearing plate 1, the wing screw 11 is loosened at the same time.

[0035] Step 2: Rotate the handrail 6 through the pin 13 until it is parallel to the first support plate 1 to complete the folding. When unfolding, repeat the above steps to complete the assembly.
