Description

Technical Field

[0001] This utility model relates to an intelligent fat-applied device, specifically an intelligent fat-applied device with a fault alarm function, belonging to the technical field of intelligent fat-applied devices. Background Technology

[0002] The programmable single-point lubrication system is a timed automatic lubrication system specifically developed for discrete equipment. It consists of upper-level control software, a terminal data acquisition unit, an end lubricator, and other accessories. This system injects grease precisely into the working bearings at constant pressure, fixed points, time, and quantity. Under the siphon effect, the grease is drawn into the raceway, while excess grease is expelled. This achieves long-term stable lubrication, ensuring the equipment bearings are in a continuously refreshed lubrication state, while simultaneously improving the level of equipment automation management and reducing operating costs.

[0003] However, in the use of existing intelligent grease dispensers, the threaded tube at the end of the dispenser needs to be connected to the oil injection tube. When the oil injection tube is directly inserted into the threaded tube, if there is a malfunction in grease discharge or the oil discharge volume is large, the oil injection tube is prone to falling off the threaded tube, causing the grease to be discharged outside the tube, which affects the effect of lubrication of the bearing. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent grease applicator with a fault alarm function to solve the above problems. The gasket drives the guide tube to engage with the threaded tube, and the locking block engages with the sleeve rod. When the limiting ring is rotated and threaded with the side wall of the sleeve rod, it can limit the locking block, thereby preventing the guide tube from falling out of the threaded tube.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an intelligent fat filler with fault alarm function, comprising a support frame, a monitoring mechanism fixed on the support frame, a threaded tube threadedly connected to the support frame, a fat filler body fixedly installed on the threaded tube, a main body mechanism installed on the fat filler body, a sealing mechanism installed at the bottom end of the support frame, the sealing mechanism comprising a limiting ring and a sleeve rod, a sleeve rod fixedly connected to the bottom end of the support frame, a locking block engaged inside the sleeve rod, a washer fixedly connected to the inner wall of the locking block, a guide tube fixedly connected to the washer, and the washer and the threaded tube engaged, a limiting ring rotatably connected to the washer, and the limiting ring and the sleeve rod threadedly connected.

[0006] Preferably, the conduit is internally connected to the threaded pipe, and the diameter of the conduit and the gasket is smaller than the diameter of the threaded pipe.

[0007] Preferably, the card block is configured in the form of a regular hexagon and is in contact with the bottom end of the support frame.

[0008] Preferably, the limiting ring and the locking block are rotatably connected, and the diameter of the limiting ring is larger than the diameter of the sleeve rod.

[0009] Preferably, the support frame is arranged in an L-shape, and the limiting ring is in contact with the bottom end of the support frame.

[0010] Preferably, the monitoring mechanism includes a fixed block and a terminal data collector. The fixed block is fixedly connected to the support frame, the terminal data collector is fixedly connected to the fixed block, and a warning light is fixedly installed on the terminal data collector.

[0011] Preferably, the two fixing blocks are located at the top of the support frame, and the two fixing blocks are arranged symmetrically.

[0012] Preferably, the fat applicator body is located at the end of the support frame away from the terminal data collector, and the fat applicator body is rotatably connected to the support frame.

[0013] Preferably, the main body includes an oil-absorbing felt and a lubricating oil bag. The lubricating oil bag is connected to the grease applicator body. The oil-absorbing felt is fixedly connected to the grease applicator body. A shell is threadedly connected to the grease applicator body. A spring is fixedly connected to the shell. A baffle is fixedly installed on the spring.

[0014] Preferably, the baffle abuts against the end of the lubricating oil bag away from the grease applicator body, and the diameter of the baffle is larger than the diameter of the spring.

[0015] The beneficial effects of this utility model are as follows: When the grease applicator body is rotated, it drives the threaded tube to rotate and can be threadedly installed inside the support frame, thereby making the grease applicator body contact the top of the support frame. Then, the washer and the guide tube are inserted into the threaded tube. Since the side wall of the washer is fixedly connected to the locking block, when the locking block moves with the washer and engages inside the sleeve rod, it can contact the bottom end of the support frame. At this time, the limiting ring installed on the side wall of the washer is rotated, so that it is threadedly connected to the side wall of the sleeve rod. When the limiting ring contacts the bottom end of the support frame, it can abut against the locking block, thereby preventing the guide tube from falling out of the threaded tube. The grease applicator body is equipped with a display screen, which can display the fault alarm codes of the equipment. Through the monitoring mechanism, the data inside the grease applicator body can also be collected, displayed and transmitted. Attached Figure Description

[0027] As a technical optimization of this utility model, the conduit 503 is internally connected to the threaded pipe 6, and the diameter of the conduit 503 and the gasket 502 is smaller than the diameter of the threaded pipe 6. When the gasket 502 is in contact with the inner wall of the threaded pipe 6, it can prevent grease leakage.

[0028] As a technical optimization of this utility model, the locking block 504 is arranged in a regular hexagonal structure, and the locking block 504 contacts the bottom end of the support frame 1. The sleeve rod 505 limits the locking block 504, which can facilitate the quick fixation of the conduit 503.

[0029] As a technical optimization of this utility model, the limiting ring 501 and the locking block 504 are rotatably connected. The diameter of the limiting ring 501 is larger than the diameter of the sleeve rod 505. When the limiting ring 501 and the sleeve rod 505 are connected, the locking block 504 can be firmly limited inside the sleeve rod 505.

[0030] As a technical optimization of this utility model, the support frame 1 is arranged in an L-shaped structure, and the limiting ring 501 contacts the bottom end of the support frame 1. The arrangement of the support frame 1 can facilitate the installation of the fat filler body 4.

[0031] As a technical optimization of this utility model, the monitoring mechanism 2 includes a fixed block 201 and a terminal data collector 202.
