Description

Technical Field

[0001] This utility model relates to the field of escalator technology, and more specifically, to an escalator operation performance measuring instrument. Background Technology

[0002] An escalator consists of a stairway (a modified plate conveyor) and handrails on both sides (a modified belt conveyor). Its main components include steps, traction chains and sprockets, guide rail system, main drive system (including motor, reduction gear, brake, and intermediate transmission links), drive shaft, stairway tensioning device, handrail system, comb plates, escalator frame, and electrical system. The steps move horizontally at the passenger entrance (to facilitate passenger boarding) and gradually form steps; near the exit, the steps gradually disappear, and the steps move horizontally again. These movements are achieved by the main and auxiliary wheels of the steps traveling along different step guide rails. As for handrail decoration, fully transparent glass panels have a certain strength, and their thickness should not be less than 6mm. In addition, fully transparent glass panels have a good decorative effect, so escalators with fully transparent flat glass panels account for the vast majority of escalators.

[0003] In practical use, traditional escalator performance measuring instruments consist of an elevator speed governor tester, a controller, and an elevator vibration analyzer, all of which are stored inside a carrying case. The case and lid of the measuring instruments are generally connected by elastic plastic clips. Over time, the elastic plastic is easily damaged, resulting in the case not being able to be sealed and making it inconvenient to carry. Utility Model Content

[0015] 1. By setting up a series of reasonable structures such as locking rings, locking grooves, and locking rods, compared with existing technologies, the locking ring is inserted into the locking groove. The top of the locking ring presses against the locking rod, causing the spring at one end of the locking rod to contract. After the top of the locking ring passes through, the spring springs back and extends the locking rod into the annular groove, preventing the locking ring from springing back and fixing it inside the locking groove. This makes the lid and the box body fixedly connected, making the box body sturdy and durable. It also prevents the common use of elastic plastic clips between the box body and the lid, which can easily damage the elastic plastic over time, resulting in the box body not being able to seal and making it inconvenient to carry.

[0016] 2. By setting up a series of reasonable structures such as foam boards, rectangular grooves, first elliptical grooves, second elliptical grooves, and square grooves, compared with the existing technology, by setting multiple rectangular grooves, multiple second elliptical grooves, and first elliptical grooves, the internal space of the box can be made to store measuring instruments, so that the device will not have the problem of insufficient internal space and inability to store measuring instruments. The foam boards set inside the box can achieve the effect of shock absorption and prevent the device from being damaged by bumps. Attached Figure Description
