Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift technology, specifically an openable and closable forklift sunroof structure. Background Technology
[0002] Forklifts are wheeled handling vehicles used for loading, unloading, stacking, and short-distance transport of palletized goods. They are widely used in ports, docks, railway stations, and various storage warehouses.
[0003] Most forklifts are equipped with overhead guards in the driver's area to protect the operator's safety. However, most overhead guards are fixed metal frames. While their canopy structure can provide good protection for the operator and prevent falling goods from injuring them, it can also obstruct the operator's view and make it difficult for the operator to observe goods that have been lifted to a high position. Furthermore, during loading and unloading operations, there are often situations where forklifts cannot reach the designated work location due to the excessive height of the overhead guard. This situation needs improvement. Utility Model Content

The two front support rods are fixedly connected to each other by multiple first connecting rods, and the two rear support rods are fixedly connected by second connecting rods. The outer tops of adjacent front support rods and first connecting rods are fixedly connected to a third connecting rod. The outer walls of the front support rods and first connecting rods are connected to a guide frame near their tops. A top cover plate is fixedly connected to the top of the guide frame. A second electric cylinder is fixedly installed on the top of the second connecting rod. The push rod end of the second electric cylinder is fixedly connected to the bottom of the top cover plate. A window is provided through the top of the top cover plate. A cover plate is hinged to the top of the top cover plate at the corresponding position of the window. A mirror is fixedly installed on the bottom of the cover plate. A connecting arm is fixedly connected to the bottom of the cover plate. A first electric cylinder is hinged to the bottom of the top cover plate. The bottom end of the connecting arm passes through the window and is hinged to the push rod end of the first electric cylinder.

[0009] As a further embodiment of this utility model: a baffle is fixedly installed on the top of the second connecting rod, the baffle is fixedly connected to the two rear support rods, and the baffle is located between the second electric cylinder and the front support rod.
[0010] As a further embodiment of this utility model: the guide frame includes angle steel that is slidably installed at the top of the outer wall of the front support rod and the rear support rod. The top of the angle steel is fixedly connected to the bottom of the top plate. Adjacent angle steels are fixedly connected to each other through connecting plates. Sliding strips are fixedly installed on the inner side wall of the angle steel. The outer wall of the front support rod is provided with a sliding groove that matches the sliding strips.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the arrangement of the guide frame and the second electric cylinder, allows for adjustment of the height of the top guard plate, thereby effectively improving the forklift's maneuverability and facilitating its passage through various height-restricted areas.
