Hoisting buckle self-locking device for saline water injection barrel

Abstract

The utility model discloses a self-locking device for a hoisting buckle of a saline water injection barrel. The self-locking device comprises a lower locking column, an outer barrel sleeve, an upper wedge inner sleeve, a spring, an upper locking column and a lower wedge inner sleeve, in the production process of the washing machine, saline water needs to be injected into the balance ring to counteract resonance generated by high-speed rotation of an inner barrel of the washing machine. When a traveling crane and manual hoisting combined mode is adopted, a saline water barrel is hoisted to a water injection platform at one end of an assembly line through the traveling crane, but saline water is inevitably prevented from shaking and overflowing, the saline water and saline water steam are corrosive, and precise instruments and equipment in a workshop can be damaged; saline water and saline water steam corrode a crane steel cable for a long time, and once the crane steel cable is broken, major safety liability accidents can be caused. In order to overcome the defects in the prior art, the utility model provides the self-locking device for the hoisting buckle of the saline water injection barrel, and the problems in the background technology are solved.

Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a self-locking device for lifting a salt water bucket with a buckle. Background Art

[0002] During the production process of washing machines, salt water needs to be injected into the balance ring to offset the resonance generated by the high-speed rotation of the drum inside the washing machine. Currently, a combination of crane and manual lifting is used to lift the salt water barrel to the water injection platform at one end of the assembly line. However, it is inevitable that salt water will spill out. Salt water and salt water vapor are corrosive and will damage the precision instruments and equipment in the workshop. Salt water and salt water vapor will corrode the crane steel cable for a long time. Once disconnected, it will cause a major safety accident. In response to the shortcomings of the existing technology, the utility model provides a self-locking device for lifting and buckling the salt water barrel, which solves the problems raised in the background technology. Utility Model Content

[0003] To achieve the above objectives, the utility model is implemented through the following technical solutions: a self-locking device for lifting a salt water barrel, comprising a lower locking post, an outer barrel sleeve, an upper wedge inner sleeve, a spring, an upper locking post, and a lower wedge inner sleeve; the upper wedge inner sleeve is fixedly connected to the inner side of the outer barrel sleeve; the lower wedge inner sleeve is movably connected to the outer barrel sleeve and can move up and down and rotate horizontally in the outer barrel sleeve; the upper locking post and the spring are placed inside the upper wedge inner sleeve, and the upper locking post can move up and down along the inner wall of the upper wedge inner sleeve.

[0004] The upper end of the lower wedge inner sleeve is designed with a forty-five-degree inclined notch, with a total of four notches that are evenly and symmetrically distributed.

[0005] The lower end of the upper wedge inner sleeve is designed with a raised point, with a total of four raised points that are evenly and symmetrically distributed.

[0006] The lower end of the lower locking column is a rectangular port, which can lock the salt water barrel cover after being rotated horizontally ninety degrees.

[0007] The lower end of the upper locking column is a locking rod, which can support the notch after contacting the notch, so that the inner sleeve of the lower wedge cannot rotate. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0011] The outer barrel sleeve is fixed under the sling, and is moved to the top of the brine barrel and pressed down. There is a rectangular opening on the brine barrel cover. The lower end of the lower lock post enters from the rectangular opening of the barrel cover of the brine barrel. After touching the inner cover of the brine barrel, the lower lock post moves in the vertical direction, pressing the upper lock post, the spring contracts, the notch contacts the raised point, and the upper end of the lower wedge inner sleeve is designed with a 45-degree inclined notch. After contacting the raised point, continue to press the lower wedge inner sleeve to rotate 90 degrees, and at the same time drive the lower lock post to rotate 90 degrees, locking the barrel cover of the brine barrel and moving upward. During lifting, the spring returns to its original position, causing the upper locking post to move downward, and the locking rod presses against the notch, preventing the lower wedge inner sleeve from rotating to prevent it from falling off during lifting. After reaching the predetermined position, lower the brine bucket and press down again. The lower locking post pushes up the locking post in the vertical direction, and the spring contracts. The notch contacts the raised point, and the upper end of the lower wedge inner sleeve is designed with a forty-five-degree inclined notch. After contacting the raised point, continue to press, and the lower wedge inner sleeve will rotate ninety degrees, driving the lower locking post to rotate ninety degrees at the same time. The rectangular port at the lower end of the lower locking post is removed from the rectangular opening of the brine bucket lid.

[0012] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
