[0002] The elevator oil cylinder is an important part of the elevator system, mainly used to provide hydraulic pressure to drive the lifting movement of the elevator. The elevator oil cylinder usually consists of a cylinder body, a piston, hydraulic oil, and an oil cylinder cover. The elevator oil cylinder cover is a component installed on the top of the elevator oil cylinder, usually used for sealing and fixing the oil cylinder.
[0003] After the elevator oil cylinder cover is fixed on the elevator oil cylinder, it is prone to being affected by external forces during long-term use, resulting in insufficient tightness and poor sealing effect, which in turn affects the performance of the oil cylinder. Moreover, the existing elevator oil cylinder covers are generally rotated and installed by directly contacting the oil cylinder cover with tools. However, due to the special use of the oil cylinder cover, its outer wall is often inevitably contaminated with oil, which causes the tool to not fit stably with the oil cylinder cover, making it difficult to quickly lock and install the oil cylinder cover, affecting the installation efficiency and installation tightness. Content of the Utility Model

[0005] To solve the above technical problems, the technical solution proposed by the utility model is: a locking structure for an elevator oil cylinder cover, including an oil cylinder cover body. A rotating ring is rotatably connected to the outer side of the lower end of the oil cylinder cover body. A locking cover is arranged above the oil cylinder cover body. A plurality of buffer structures are connected between the lower edge of the locking cover and the rotating ring. A plurality of first engaging teeth are arranged at the upper edge of the oil cylinder cover body. A plurality of second engaging teeth are arranged below the locking cover to cooperate with the first engaging teeth. A plurality of protruding plates are connected to the side wall of the locking cover. A spare hole is arranged at the center above the locking cover and the oil cylinder cover body.
[0006] Furthermore, the outer diameter of the locking cover is larger than the outer diameter of the oil cylinder cover body. The buffer structures are evenly spaced and arranged on the outer side of the oil cylinder cover body. The buffer structure includes a telescopic rod and a spring. The spring is sleeved outside the telescopic rod. The upper and lower ends of the telescopic rod and the spring are respectively connected to the locking cover and the rotating ring.
[0007] Based on the above features, the buffer structures are evenly spaced and arranged, which not only evenly distributes the force of the locking cover pressing down, ensures its stable contact with the oil cylinder cover body, but also can effectively protect the side of the oil cylinder cover body.
[0008] Further, the first set of teeth and the second set of teeth are respectively arranged around the upper edge of the cylinder head body and the lower edge of the locking cover, and the first set of teeth and the second set of teeth correspond one by one and cooperate up and down.
[0009] Based on the above characteristics, the cooperation between the first set of teeth and the second set of teeth enables the locking cover to drive the cylinder head body to rotate stably.
[0010] Further, a number of observation ports are provided on the upper wall of the locking cover, and a number of anti-slip patterns are provided on the side wall and the protruding plate of the locking cover.
[0011] Based on the above characteristics, the observation ports facilitate observing the rotation of the cylinder head body, thus ensuring effective sealing. The anti-slip patterns can ensure the stable rotation of the tightening cover, which is labor-saving and reliable.
[0012] Further, the spare holes on the locking cover are aligned vertically and communicate with the spare holes on the cylinder head body, and the cross-section of the spare holes is a regular hexagon.
[0013] Based on the above characteristics, the regular hexagon-shaped spare holes facilitate directly controlling the rotation of the cylinder head body when the locking cover fails and also facilitate finding a suitable tool.
[0014] The advantages of the present utility model compared with the prior art are as follows: A rotating ring is provided on the outer side of the lower end of the cylinder head body, a locking cover with a larger outer diameter is provided above it, and a buffer structure is provided on the side. It can effectively protect the cylinder head body from the side and above, prevent the external structure from applying force to the cylinder head body and causing it to loosen, ensure a good sealing and locking effect, be safe and reliable. The cooperation between the first gear and the second gear enables the locking cover to drive the cylinder head body to rotate stably for sealing, avoiding direct contact with the oil-stained cylinder head body, and the protruding plate can further ensure the stable rotation of the locking cover, thus realizing the rapid and stable locking of the cylinder head body.
