Description

Technical Field

[0001] The utility model relates to the technical field of ultra-thin elevator locks, in particular to an ultra-thin elevator lock which is easy to maintain. Background Art

[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. There are also stepped types, with treads mounted on tracks and running continuously, serving as fixed lifting equipment on specified floors. A vertical lift has a car that runs between at least two rows of vertical rigid guide rails. During use, the elevator can respond to emergencies through the elevator lock. The elevator lock is fixed by threads and tightly combined with the elevator. During use, the nuts become loose, which causes the elevator lock to fail to open normally.

[0003] Patent announcement number CN215287621U discloses an automatic reset elevator lock with a toggle device, including a fixed disk and a key. A key is provided at the right end of the fixed disk, and the key is laterally inserted into the fixed disk. A ring is provided on the surface of the key at the right position, and the ring is sleeved on the key. A threaded section is provided at the left end of the fixed disk, and the threaded section is integrally formed at the fixed disk. Nut 2 can rotate relative to the screw rod under the action of external force. When nut 2 rotates clockwise, nut 2 gradually approaches the fixed end. When nut 2 rotates counterclockwise, nut 2 gradually moves away from the fixed end. The hexagonal groove is located inside the fixed end. Through the reinforcement of bolts, the stability of the elevator lock can be greatly improved, which is convenient for responding to emergencies in the later stage. The setting has a simple structure and is easy to install and disassemble. The elevator lock can be further optimized through this setting.

[0004] However, the current elevator locks have the following problems: dust is easily accumulated during daily use of elevator locks, which requires manual cleaning, thereby increasing the workload of the staff, and easily causing errors in the use of the elevator locks, making it difficult to ensure the smooth operation of the elevator locks. Therefore, we propose an ultra-thin elevator lock that is easy to maintain. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides an ultra-thin elevator lock that is easy to maintain, solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model is realized by the following technical solutions: An ultra-thin elevator lock that is convenient for maintenance, including an insertion tube, a housing is fixedly connected to the side of the insertion tube, a threaded groove is opened on the side of the housing, a fixed disk is fixedly connected to the side of the housing, a jack is opened on the side of the fixed disk, and a dust removal device is arranged at the bottom of the fixed disk; the dust removal device includes an airbag, the top of the airbag is fixedly connected to the bottom of the fixed disk, a ventilation tube penetrates through the top of the airbag, the bottom of the airbag is fixedly connected to a connecting plate, a connecting rod is fixedly connected to the top of the connecting plate, and the end of the connecting rod away from the connecting plate is fixedly connected to a pressing block. A spring is fixedly connected to the side of the fixed disk, the end of the spring away from the fixed disk is fixedly connected to a connecting long plate, a convex block is fixedly connected to the side of the connecting long plate, a knocking rod is fixedly connected to the side of the connecting long plate, the side of the convex block is on the displacement track of the pressing block, the side of the fixed disk is on the displacement track of the knocking rod, there are two knocking rods in total, and they are symmetrically arranged along the vertical central axis of the fixed disk. The knocking rods are fixedly connected to the spring through the connecting long plate, and the convex blocks are fixedly connected to the spring through the connecting long plate. Repeatedly move the connecting plate up and down. When the connecting plate is lifted, the connecting plate presses the upper airbag. After the airbag receives the pressing force from the connecting plate, the gas inside the airbag is sprayed into the inside of the jack through the ventilation tube, causing the dust on the inner wall of the jack to fall. At the same time, when the connecting plate moves upward, the connecting plate drives the connecting rod to move upward. When the connecting rod moves upward, the connecting rod drives the pressing block to move upward. When the pressing block moves upward, the pressing block presses the side of the upper convex block. After the convex block receives the pressing force from the pressing block, the convex block starts to move outward. When the convex block moves outward, the convex block drives the connecting long plate on the side to move outward. When the connecting long plate moves outward, the connecting long plate stretches the spring, increasing the length of the spring. At the same time, when the connecting long plate moves outward, the connecting long plate also drives the knocking rod to move outward. Then, when the connecting plate moves downward, the connecting plate drives the connecting rod to move downward. When the connecting rod moves downward, the connecting rod drives the pressing block to move downward. When the pressing block moves downward, the pressing force of the pressing block on the convex block disappears. Then, the convex block starts to move inward through the elastic force of the spring on the side of the connecting long plate. When the connecting long plate moves inward, the connecting long plate drives the knocking rod on the side to move inward.

[0007] According to the above technical solution, a lubricating device is provided on the side of the connecting plate. The lubricating device includes a fixing plate, the side of the fixing plate is fixedly connected to the side of the connecting plate, a pressing rod is fixedly connected to the top of the fixing plate, a storage oil cylinder is fixedly connected to the side of the fixed disk, a through oil pipe penetrates through the side of the storage oil cylinder, a pressing key is provided at the bottom of the storage oil cylinder, and the control end of the pressing key is on the displacement track of the pressing rod. One end of the through oil pipe is fixedly penetrated on the side of the jack. The fixing plate is fixedly connected to the airbag through the connecting plate, the pressing rod is fixedly connected to the connecting plate through the fixing plate, and the pressing key is fixedly connected to the fixed disk through the storage oil cylinder. When the connecting plate moves upward, the connecting plate drives the fixing plate to move upward. When the fixing plate moves upward, the fixing plate drives the pressing rod to move upward. When the pressing rod moves upward, the pressing rod presses the pressing key above. After the pressing key receives the pressing force from the pressing rod, the pressing key controls the lubricating oil inside the storage oil cylinder to be sprayed outwards through the through oil pipe.

[0008] The utility model provides an ultra-thin elevator lock that is convenient for maintenance. It has the following beneficial effects:

[0009] (1) Through the setting of the dust removal device in the utility model, the connecting plate, the airbag, the ventilation pipe, the jack, the connecting rod, the extrusion block, the convex block, the connecting long plate, the spring, and the knocking rod cooperate to drive the knocking rod to move inward to knock the fixed disk on the side, further causing the dust on the inner wall of the jack to fall off, thereby ensuring that the inner wall of the jack is thoroughly cleaned, and being able to continuously maintain the clean state of the jack, reducing the need for manual operation, lightening the work burden, and ensuring the normal operation of the elevator lock.

[0010] (2) Through the setting of the lubricating device in the utility model, the connecting plate, the fixing plate, the pressing rod, the pressing key, the storage oil cylinder, and the through oil pipe cooperate to drive the pressing key to control the lubricating oil inside the storage oil cylinder to be sprayed outwards through the through oil pipe, so that the lubricating oil is sprayed onto the inner wall of the jack, which can prevent the parts from being stuck or jammed due to friction, ensure the normal operation of the jack, reduce the possibility of faults, and improve the reliability and stability of the equipment.
