[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth. Example

[0025] Reference Figure 1-4 In the first embodiment of this utility model, a fixing component 1 is provided, including a reverse rope wheel 101 and a fixing seat 102. The surface of the reverse rope wheel 101 is rotatably connected to the inner wall of the fixing seat 102. A lubrication mechanism 2 is provided at the upper end of the fixing seat 102. A locking mechanism 3 is provided on the surface of the lubrication mechanism 2. The lubrication mechanism 2 is used to lubricate the reverse rope wheel 101 when needed, and the locking mechanism 3 is used to lock the lubrication mechanism 2.

[0026] Specifically, the fixing component 1 rotatably connects the anti-cord wheel 101 to the fixing base 102, and sets a locking mechanism 3 and a lubrication mechanism 2 on the fixing base 102. This solves the problems of unstable installation of the lubrication device and difficulty in controlling the lubrication timing in the traditional structure. The locking mechanism 3 ensures that the lubrication mechanism 2 is firmly fixed in the working state, preventing vibration and loosening, and ensuring the continuity and safety of the lubrication process. The lubrication mechanism 2 enables the anti-cord wheel 101 to automatically start oil supply during operation and lubricate as needed.

[0027] Furthermore, when it is necessary to use the anti-cord pulley 101 for work, the lubrication mechanism 2 can be locked by the locking mechanism 3 first, and then the anti-cord pulley 101 can be lubricated by the lubrication mechanism 2 when needed. Example

[0028] The second embodiment of this utility model provides a lubrication mechanism 2 including a movable seat 201, a mounting box 202, a feed inlet 203, a double-ended reciprocating screw 204, transmission blocks 205, a mating plate 206, an electromagnetic clutch 207, and a reducer 208. The upper end of the movable seat 201 is fixedly connected to the lower end of the mounting box 202. The feed inlet 203 is located at the upper end of the mounting box 202. The two ends of the double-ended reciprocating screw 204 are respectively threaded to the inner walls of the two transmission blocks 205. The surface of the transmission blocks 205 is fixedly connected to the surface of the mating plate 206. The upper output end of the electromagnetic clutch 207 is connected to the lower input end of the reducer 208. The movable seat 201 is fixedly connected to the rear end of the fixed seat 102 via a rotating shaft. The front end of the movable seat 201 is in contact with the front end of the fixed seat 102. The two ends of the double-headed reciprocating screw 204 are rotatably connected to the inner wall of the mounting box 202. The surface of the double-headed reciprocating screw 204 is fixedly connected to the output end of the reducer 208 via a coupling. The surface of the electromagnetic clutch 207 is fixedly connected to the input end surface of the anti-rope wheel 101 via a coupling. The inner wall of the movable seat 201 is rotatably connected to the surface of the anti-rope wheel 101. The surface of the mating plate 206 is slidably connected to the inner wall of the mounting box 202 via a sliding groove. The two mating plates 206 are in contact with each other on their sides.

[0029] Specifically, the lubrication mechanism 2 drives the two transmission blocks 205 to move synchronously in opposite directions through the transmission cooperation between the reducer 208 and the double-headed reciprocating screw 204, thereby causing the mating plate 206 to slide to control the opening and closing of the discharge port of the mounting box 202. This solves the problem that traditional lubrication methods are difficult to supply oil evenly during equipment operation. The electromagnetic clutch 207 realizes the power linkage between the lubrication mechanism 2 and the anti-rope wheel 101, and automatically starts lubrication only after locking is completed, avoiding the waste of lubricating fluid and operational risks.

[0030] Furthermore, the first step is to assemble and fix the locking mechanism 3, ensuring that the front end of the movable seat 201 is tightly fitted and aligned with the front end of the fixed seat 102 to guarantee the stability of the overall structure. Then, the adjusting screw 301 is turned using an external tool. The two ends of the screw are rotatably connected to the inner walls of the bearing seats 302 on the fixed seat 102 and the movable seat 201, respectively, forming a stable rotational support. The screw surface is provided with a mating block 303 that engages with its thread. When the screw rotates under the action of rotation, the mating block 303 cannot rotate with the screw due to the guide restriction, but can only make a vertical linear movement along the inner wall of the movable seat 201. This linear movement drives the locking block 304, which is fixedly connected to the mating block 303, to move synchronously, gradually embedding it into the locking groove inside the fixed seat 102, thus realizing the connection between the movable seat 201 and the fixed seat 102 and completing the pre-tightening fixation of the anti-cord wheel 101 before operation, providing structural protection for subsequent transmission and lubrication operations. Example

[0031] The third embodiment of this utility model provides a locking mechanism 3 including an adjusting screw 301, a bearing seat 302, a mating block 303, and a locking block 304. The surface of the adjusting screw 301 is rotatably connected to the inner wall of the bearing seat 302, the surface of the mating block 303 is fixedly connected to the surface of the locking block 304, the surfaces of the two bearing seats 302 are respectively fixedly connected to the surfaces of the fixed seat 102 and the movable seat 201, the surface of the adjusting screw 301 is threadedly connected to the inner wall of the mating block 303, the surface of the locking block 304 is slidably connected to the inner wall of the movable seat 201 through a sliding groove, and the surface of the locking block 304 is in contact with the inner wall of the fixed seat 102.

[0032] Specifically, the locking mechanism 3 drives the locking block 304 to move vertically under the guide of the slide groove through the threaded transmission of the adjusting screw 301 and the mating block 303, so that it is embedded in the fixed seat 102 to achieve locking. This effectively solves the problem of unstable connection and easy loosening between the movable seat 201 and the fixed seat 102, ensuring the structural reliability of the anti-rope wheel 101 during operation. At the same time, the locking and power transmission are linked, avoiding manual intervention and improving operational safety and work efficiency.

[0033] Furthermore, after locking, the anti-corrosion pulley 101 is activated to begin rotating. The anti-corrosion pulley 101, through a coupling, drives the fixed electromagnetic clutch 207 to rotate synchronously. A reducer 208 is installed at the upper end of the electromagnetic clutch 207. The speed output by the anti-corrosion pulley 101 is reduced by the reducer 208 to meet the working requirements of the subsequent transmission mechanism. The output end of the reducer 208 is fixedly connected to a double-ended reciprocating screw 204, thereby transmitting power to the screw. The special structure of the double-ended reciprocating screw 204 is that its two ends have opposite thread directions, i.e., one end is left-handed and the other end is right-handed. Transmission blocks 205 are respectively equipped on the threaded sections at both ends to mesh with the threads. As the double-ended reciprocating screw 204 rotates... Driven by the reducer 208, the two transmission blocks 205 rotate at a constant speed. Under the action of the screw, the two transmission blocks 205 move synchronously in opposite directions along the screw axis, thereby driving the mating plate 206 fixedly connected to it to produce relative displacement. The movement of the mating plate 206 directly acts on the lower opening structure of the mounting box 202. When the two mating plates 206 move away from each other under the action of the transmission blocks 205, the discharge channel at the bottom of the mounting box 202 is gradually opened, forming a flow path for the lubricating fluid. At this time, the operator can inject the lubricating fluid from the inlet 203 at the top of the mounting box 202. Under the action of gravity, the liquid flows downward along the inside of the box and is evenly discharged through the opened outlet, directly covering the surface of the rotating anti-corrosion wheel 101 below, realizing the automatic lubrication function.

[0034] When the anti-cord pulley 101 is needed for operation, the locking mechanism 3 must first be assembled and fixed. The front end of the movable seat 201 and the front end of the fixed seat 102 must be tightly fitted and aligned to ensure the stability of the overall structure. Then, the adjusting screw 301 is turned using an external tool. Both ends of the screw are rotatably connected to the inner walls of the bearing seats 302 on the fixed seat 102 and the movable seat 201, respectively, forming a stable rotational support. The screw surface is provided with a mating block 303 that engages with its thread. When the screw rotates under rotational action, the mating block 303, due to guiding constraints, cannot rotate with the screw and can only move along... The inner wall of the movable seat 201 moves vertically in a linear motion. This linear motion drives the locking block 304, which is fixedly connected to the mating block 303, to move synchronously, gradually embedding it into the locking groove inside the fixed seat 102. The locking groove is equipped with a corresponding locking buckle, achieving the connection between the movable seat 201 and the fixed seat 102. This completes the pre-tightening and fixing of the anti-corrosion pulley 101 before operation, providing structural protection for subsequent transmission and lubrication operations. After locking, the anti-corrosion pulley 101 is activated to begin rotating. The anti-corrosion pulley 101, through a coupling, drives the electromagnetic clutch 207, which is fixed to it, to rotate synchronously. A reducer 208 is installed at the upper end of 207. The speed output of the anti-reverse pulley 101 is reduced by the reducer 208 to meet the working requirements of the subsequent transmission mechanism. The output end of the reducer 208 is fixedly connected to a double-ended reciprocating screw 204, thereby transmitting power to the screw. The special structure of the double-ended reciprocating screw 204 is that it has reciprocating threads at both ends, and transmission blocks 205 are respectively equipped on the threaded sections at both ends to mesh with the threads. As the double-ended reciprocating screw 204 rotates at a constant speed under the drive of the reducer 208, the two transmission blocks 205 move in opposite directions along the screw axis under the action of the threads. The direction moves synchronously, thereby causing the mating plate 206 fixedly connected to it to generate relative displacement. The movement of the mating plate 206 directly acts on the lower opening structure of the mounting box 202. When the two mating plates 206 move away from each other under the drive of the transmission block 205, the discharge channel at the bottom of the mounting box 202 is gradually opened, forming a flow path for the lubricating fluid. At this time, the lubricating fluid injected from the inlet 203 at the top of the mounting box 202 flows downward along the inside of the box under the action of gravity, and is evenly discharged through the opened outlet, directly covering the surface of the rotating anti-corrosion wheel 101 below, realizing the automatic lubrication function.

[0035] In summary, by adjusting the linkage between the screw and the locking block, the reducer driving the double-headed reciprocating screw to drive the transmission block to move in the opposite direction, and the coordinated action of the mating plate controlling the opening and closing of the mounting box, a stable lubrication effect is achieved by automatically opening the lubrication channel and continuously supplying oil during the operation of the anti-rope wheel.
