Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a self-lubricating pulley. Background Technology
[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body, including the necessary computer software. Medical devices include medical equipment and medical consumables. Their efficacy is primarily obtained through physical means, not through pharmacological, immunological, or metabolic means, or although these means are involved, they only play an auxiliary role. The purpose of medical devices is the diagnosis, prevention, monitoring, treatment, or alleviation of diseases. However, medical devices often require changing the direction of pulleys. A pulley is a simple machine consisting of a grooved disc that can rotate around a central axis and a flexible cable passing over the disc. However, existing pulleys often have poor lubrication, which easily leads to pulley aging, causing jamming during use and reducing their lifespan. Utility Model Content
[0003] The purpose of this invention is to provide a self-lubricating pulley to solve the problems mentioned in the background art, such as poor lubrication, which easily leads to pulley aging, causing the pulley to jam during use, and reducing the service life of the pulley.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a self-lubricating pulley, comprising a main body configured as an I-shaped structure, and side plates fixedly connected to both ends of the main body; The side plate has multiple holes embedded around its surface. The side plate is connected to an extrusion mechanism, and the extrusion mechanism includes: a storage box is fixedly connected to the side plate, and a heat-conducting block is installed on the bottom surface of the storage box. The end of the heat-conducting block is inserted into the inside of the storage box and connected to a memory material block, and the memory material block is located inside the storage box. The storage box has symmetrically arranged storage bladders inside, and the bottom of the storage bladder is connected to an air tube, and the other end of the air tube penetrates through the bottom of the storage box.
[0005] Preferably, the main body is made of nylon, and the interior of the main body is a hollow structure.
[0006] By adopting the above technical solution, the main body is made of nylon material, which reduces friction between the main body and the pulley, making the pulley more lubricated.
[0007] Preferably, the surface of the side plate is provided with a limiting mechanism, and the limiting mechanism includes: two mounting plates fixedly connected to the surfaces of the side plates, and an electromagnet mounted on the surface of the mounting plate, the end of the electromagnet being fixedly connected to a limiting block, and the end of the limiting block being embedded in the surface of the side plate.
[0008] By adopting the above technical solution, the limiting mechanism can lock the rope, which can improve the stability of the pulley operation.
[0009] Preferably, the side plates are circular and symmetrically arranged on both sides of the main body.
[0010] By adopting the above technical solution, the side panels can increase the height of the main body and prevent the ropes from falling off.
[0011] Preferably, the limiting block is configured as an arc-shaped structure, and the end of the limiting block is correspondingly set to the middle of the main body. The surface of the main body is provided with a sliding groove, and the two sides of the limiting block are set on both sides of the sliding groove of the main body. The limiting block and the main body are slidably connected.
[0012] Using the above technical solution, the bottom of the limiting block is in contact with the surface of the rope, and the end of the limiting block is in contact with the rope, which can fix the rope.
[0013] Preferably, the bottom of the heat-conducting block is located in the middle of the main body, and the heat-conducting block is generally arc-shaped.
[0014] Using the above technical solution, the heat of the heat-conducting block increases. When the heat-conducting block increases to the point of being movable, it expands and can compress the storage bag.
[0015] Preferably, the two sides of the memory material block are in contact with the surface of the storage bladder, and the end of the trachea is located in the middle of the main body.
[0016] Using the above technical solution, when the storage bladder is squeezed, the gas inside the storage bladder enters the trachea and is ejected through the trachea.
[0017] Compared with the prior art, the beneficial effects of this utility model are: the self-lubricating pulley: 1. An extrusion structure is set up to automatically lubricate the pulley. When the bottom of the heat-conducting block rubs against the rope, heat is generated. At this time, the heat-conducting block transfers heat to the inside of the memory material block. When the memory material block heats up to the moving temperature, it expands and can squeeze the storage bag outward, allowing the lubricating oil inside the storage bag to be discharged. The lubricating oil falls on the surface of the main body to lubricate the main body. At the same time, the main body is made of nylon, which itself has a lubricating effect, improving the practicality of the pulley. 2. A limit mechanism is provided to fix the rope. When the pulley stops working, the electromagnet can be energized. At this time, the end of the electromagnet pops out and pushes the limit block to move. The end of the limit block pushes the rope inward and fixes the rope between the limit block and the main body, preventing the rope from continuing to slide and improving the stability of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-6 This utility model provides a technical solution: a self-lubricating pulley, including a main body 10, a side plate 20, a hole 201, a mounting plate 30, an electromagnet 301, a limiting block 302, a storage box 40, a heat-conducting block 401, a memory material block 402, a storage bladder 403, and an air tube 404. This pulley can be automatically lubricated during use. The specific implementation method is as follows: The main body 10 is configured as an I-shaped structure, and side plates 20 are fixedly connected to both ends of the main body 10; multiple holes 201 are embedded around the surface of the side plates 20, and an extrusion mechanism is connected to the surface of the side plates 20, and the extrusion mechanism includes; a storage box 40 is fixedly connected to the surface of the side plates 20, and a heat-conducting block 401 is installed on the bottom surface of the storage box 40. The end of the heat-conducting block 401 is inserted into the interior of the storage box 40 and connected to a memory material block 402, and the memory material block 402 is disposed inside the storage box 40. The interior of the storage box 40 is symmetrically arranged with storage... The storage sac 403 is connected to the bottom of the storage sac 403 by an air tube 404, and the other end of the air tube 404 passes through the bottom of the storage box 40. The main body 10 is made of nylon and has a hollow structure inside. The side plate 20 is circular and is symmetrically arranged on both sides of the main body 10. The bottom of the heat-conducting block 401 is located in the middle of the main body 10 and the heat-conducting block 401 is arc-shaped. The two sides of the memory material block 402 are in contact with the surface of the storage sac 403, and the end of the air tube 404 is located in the middle of the main body 10.
[0022] The rope passes through the interior of the main body 10, with its surface in contact with the bottom of the heat-conducting block 401. Simultaneously, the rope passes between the limiting block 302 and the main body 10. As the rope slides on the surface of the main body 10 (which is made of nylon, providing good lubrication), one side of the rope rubs against the heat-conducting block 401. This friction generates heat, which is then transferred to the interior of the memory material block 402, heating it. As the temperature of the memory material block 402 gradually increases, it expands when it reaches a suitable temperature. This expansion causes the sides of the memory material block 402 to compress the storage bladder 403. Under this pressure, the lubricating oil inside the storage bladder 403 enters the air pipe 404, which then distributes the lubricating oil onto the surface of the main body 10, thus lubricating it.
[0023] This pulley can be used to secure the rope. The specific implementation method is as follows: The surface of the side plate 20 is provided with a limiting mechanism, which includes: mounting plates 30 are fixedly connected to the surfaces of the two side plates 20, and electromagnets 301 are mounted on the surface of the mounting plates 30. The ends of the electromagnets 301 are fixedly connected to limiting blocks 302, and the ends of the limiting blocks 302 are embedded in the surface of the side plate 20. The limiting blocks 302 are set with an arc-shaped structure, and the ends of the limiting blocks 302 are corresponding to the middle of the main body 10. The surface of the main body 10 is provided with a sliding groove, and the two sides of the limiting blocks 302 are set on both sides of the sliding groove of the main body 10. The limiting blocks 302 and the main body 10 are slidably connected.
[0024] When the rope stops moving and the pulley stops rotating, the electromagnet 301 can be activated, causing its end to pop out. The end of the electromagnet 301 pushes the limiting block 302 to move, causing both ends of the limiting block 302 to slide inside the groove of the main body 10. At this time, the limiting block 302 moves towards the surface of the main body 10, and the end of the limiting block 302 fits against the surface of the rope, fixing the rope between the limiting block 302 and the main body 10. This allows the position of the rope to be fixed.
[0025] Working principle: When using this self-lubricating pulley, a heat-conducting block 401, a memory material block 402, a storage bladder 403, and an air tube 404 are provided for automatic lubrication. An electromagnet 301 and a limiting block 302 are provided to fix the rope, increasing the overall practicality.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
