Description

Technical Field

[0001] This utility model relates to the field of transport trolley technology, and in particular to an adjustable excimer laser cavity transport trolley. Background Technology

[0002] In the field of laser technology, excimer lasers are widely used in materials processing, medical treatment, scientific research and other fields due to their high energy density, high monochromaticity and high directionality. In modern industrial production, the transportation of excimer laser cavities is an important step.

[0003] During the use of transport trolleys, the traditional structure of transport trolleys is relatively fixed and lacks flexibility, making it difficult to meet the height requirements of different working environments. This limitation affects the handling efficiency and makes them inconvenient for practical use.

[0004] Therefore, to address the aforementioned issue of the inconvenience in flexibly adjusting the height of the trolley according to actual needs, an adjustable excimer laser cavity transport trolley can be designed. During the use of the transport trolley, the slide can drive the lower sliding rod to move smoothly towards the front. The two ends of the sliding rod can drive the upper left end of the two inclined support columns to be lifted through the sliding grooves on both sides. The entire adjustment process is smooth and efficient, and the height of the trolley can be flexibly adjusted according to actual needs, improving handling efficiency and operational safety. Utility Model Content

[0005] In order to overcome the problem that traditional transport trolleys lack adjustment mechanisms during use, which not only affects the handling efficiency but also poses safety hazards and reduces the overall safety of the operation, improvements are urgently needed. Furthermore, it is inconvenient to flexibly adjust the height of the trolley according to actual needs.

The upper frame is provided above the lower frame, and a support platform is fixedly provided on the top of the upper frame. Two sets of diagonal braces are provided on both sides of the upper part of the lower frame, and two sets of diagonal bracing columns are provided on both sides of the upper part of the lower frame. A connecting shaft is rotatably provided between the diagonal braces and the diagonal bracing columns. Two sets of guide grooves are provided on both sides of the top of the lower frame. A guide wheel is rotatably provided on the upper left side of the diagonal bracing column, and a sliding groove is provided through the upper left sidewall of the diagonal bracing column. A slide rail is fixedly provided inside the upper frame, and a lead screw is rotatably provided inside the slide rail. A handwheel is fixedly provided at one end of the lead screw, and a slide block is provided on the sidewall of the lead screw. A sliding rod is rotatably provided on the lower inner wall of the slide block.

[0007] Preferably, during the use of the transport trolley, firstly, turning the handwheel will drive the lead screw to rotate, which in turn will drive the slide block to move smoothly forward along the slide rail. During the movement of the slide block, the slide block will drive the lower sliding rod to move smoothly forward. The two ends of the sliding rod can drive the upper left end of the two diagonal support columns to be raised through the sliding grooves on both sides. At this time, the upper left end of the diagonal support column can drive the guide wheel to slide smoothly along the guide groove. At the same time, the lower left end of the diagonal support rod can drive another set of guide wheels to slide smoothly along the guide groove. This allows for height adjustment of the upper frame and support platform. When the appropriate height is reached, the upper frame and support platform are locked in their current positions. In addition, the diagonal support rod and the diagonal support column are rotatably connected by a connecting shaft, which enhances the structural stability of the trolley. In summary, the entire adjustment process is smooth and efficient, and the height of the trolley can be flexibly adjusted according to actual needs, improving handling efficiency and operational safety.

[0008] Preferably, multiple sets of universal wheels are provided on both sides of the bottom of the lower frame, and multiple sets of guide grooves are provided. Two other sets of guide grooves are provided on both sides of the bottom of the upper frame. The guide wheels are slidably connected to the guide grooves. Multiple sets of guide wheels are provided. Another set of guide wheels is rotatably located at the lower left side of the diagonal brace. The slide block is threadedly connected to the lead screw. Both ends of the sliding rod are slidably connected to the diagonal brace columns on both sides through the sliding grooves on both sides.

[0009] Preferably, a rotating shaft is provided at the lower right end of the diagonal brace, and two sets of fasteners are fixedly provided on both sides of the top front end of the lower frame. The lower right end of the diagonal brace is rotatably connected to the fasteners through the rotating shaft.

[0010] Preferably, the upper right end of the diagonal brace is provided with an installation shaft, and two sets of mounting parts are fixedly provided on both sides of the bottom front end of the upper frame. The upper right end of the diagonal brace is rotatably connected to the mounting parts through the installation shaft.

[0011] Preferably, a fixing block is fixedly provided on the lower side wall of the handwheel, and a limit rod is provided inside the fixing block, which is slidably connected to the inside of the fixing block.

[0012] Preferably, the front side wall of the upper frame has multiple sets of limiting holes, one end of the limiting rod is engaged with the inside of the limiting hole, and a limiting ring is fixedly provided on the side wall of one end of the limiting rod.

[0013] Preferably, a limiting spring is fixedly installed on the inner wall of the limiting ring, with one end of the limiting spring fixedly connected to the inner wall of the limiting ring and the other end of the limiting spring fixedly connected to the inner wall of the fixing block.

[0014] The beneficial effects of this utility model are: During the operation of the transport trolley, firstly, turning the handwheel will rotate the lead screw, which will then move the slide block smoothly forward along the slide rail. As the slide block moves, it will also move the lower sliding rod smoothly forward. The two ends of the sliding rod can then lift the upper left side of the two diagonal support columns via sliding grooves on both sides. At this time, the upper left side of the diagonal support column will drive the guide wheel to slide smoothly along the guide groove. Simultaneously, the lower left side of the diagonal support rod will drive another set of guide wheels to slide smoothly along the guide groove. This allows for height adjustment of the upper frame and support platform. When the appropriate height is reached, the upper frame and support platform are locked in their current positions. Furthermore, the diagonal support rod and the diagonal support column are rotatably connected via a connecting shaft, enhancing the structural stability of the trolley. In summary, the entire adjustment process is smooth and efficient, allowing for flexible height adjustment according to actual needs, thus improving handling efficiency and operational safety.
