DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0019] Example 1

[0020] This embodiment provides a double-layer adjustment device for a trolley bottom plate with overlapping holes, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a fixed plate 1 with multiple base plate mounting grooves. A reference base plate 12 is mounted in one of the base plate mounting grooves, and lower base plates 14 are mounted in the remaining base plate mounting grooves. An upper base plate 11 is mounted on the lower base plate 14 via a rotating pin 8.

[0021] like Figure 3 As shown, a lower bolt is installed between the middle of the lower bottom plate 14 and the side wall of the fixed plate 1. The lower bolt is used to adjust the front and rear position of the lower bottom plate 14. An upper bolt is installed between a corner of the upper bottom plate 11 and the side wall of the fixed plate 1. The upper bolt is used to pull the upper bottom plate 11 to rotate around the rotating pin 8.

[0022] The lower bottom plate 14 is provided with a double-sided compression spring 4. One end of the double-sided compression spring 4 is elastically pressed against the side wall of the fixed plate 1, and the other end of the double-sided compression spring 4 is elastically pressed against the upper bottom plate 11. The double-sided compression spring refers to a structure in which springs are respectively installed on opposite sides of a fixed block, so that the upper bottom plate is always subjected to elastic pressing force.

[0023] In order to ensure that the lower floor can move forward and backward smoothly, a plurality of lower front and rear adjustment holes 7 are provided on the lower floor 14. The lower front and rear adjustment holes 7 are parallel to the lower bolts. In order to ensure the stability of the rotation adjustment of the upper floor, an upper rotation adjustment hole 9 is obliquely provided at one corner of the upper floor 11.

[0024] In order to facilitate fine-tuning of the reference nozzle, an adjustment screw 13 is provided on one side of the reference base plate 12, and the adjustment screw 13 is used to adjust the position of the reference nozzle installed on the reference base plate. The adjustment screw includes a columnar portion with a cross groove on the top and a conical transition portion connected to the bottom of the columnar portion, and a threaded rod is connected to the bottom of the conical transition portion. The adjustment principle is to adjust by relying on the contact position between the conical transition portion and the side wall of the reference base plate. That is, when the adjustment screw is tightened, the conical transition portion will move downward, thereby pressing the reference base plate to move to one side.

[0025] In this embodiment, a pin hole 10 is opened at a corner of the upper bottom plate 11 corresponding to the position of the rotating pin 8, and the pin hole and the upper bolt are located on a diagonal line.

[0026] Example 2

[0027] This embodiment provides a double-layer adjustment device for a trolley bottom plate with overlapping holes, and the main difference from the first embodiment is that in this embodiment, the side walls of the fixing plate are respectively provided with upper bolt assembly holes 2 and lower bolt assembly holes. The above bolt assembly holes are all strip-shaped holes.

[0028] The upper bottom plate 11 is provided with an upper threaded hole 5 at a position corresponding to the upper bolt assembly hole 2. After the upper bolt passes through the upper bolt assembly hole 2, it is threadedly connected in the upper threaded hole 5.

[0029] The lower bottom plate 14 is provided with lower threaded holes 15 at positions corresponding to the lower bolt assembly holes. After the lower bolts pass through the lower bolt assembly holes, they are threadedly connected in the lower threaded holes 15.

[0030] For the sake of distinction, the lower bolt assembly holes can be divided into a first lower bolt assembly hole 3 and a second lower bolt assembly hole 6. The second lower bolt assembly hole needs to pass through two side walls of the fixing plate.
