Chain block operating angle adjusting device and slider assembling structure

Abstract

The invention discloses a chain block operating angle adjusting device and slider assembling structure. The chain block operating angle adjusting device and slider assembling structure comprises a block body, a slider and a hand pulling chain; the block body is connected with the hand pulling chain; a hand chain wheel housing is arranged at the outer side of the hand pulling chain; the hand chain wheel housing sleeves a pressing plate; the pressing plate is connected with the block body through a screw; the hand chain wheel housing is provided with an enlarged opening; the slider is provided with a slider guide groove; the slider is connected with the hand chain wheel housing via the slider guide groove and the enlarged opening; a baffle is arranged at the inner side of the hand chain wheel housing; the baffle is integrally connected with the hand chain wheel housing through the screw and a nut. The chain block operating angle adjusting device and slider assembling structure is convenient to use, accurate and reasonable in design, easy to dismount and replace, convenient to repair, free of assembly loss, simple in slider manufacturing, capable of realizing large-scale production, relatively high in percent of pass of manufacturing, capable of realizing adjustable operation of operating angle on the circumference, and suitable for wide popularization and application.

Description

[0001] 【Technical field】 [0002] The invention relates to a chain hoist, in particular to a chain hoist operating angle adjustable device and a sliding block assembly structure. [0003] 【Background technique】 [0004] At present, when the existing hand chain hoists are in use, the assembly structure of the guide sliders is difficult to assemble the sliders, the manufacturing pass rate is low, it is not easy to replace, and the disassembly can only be damaged, the scrap rate is high, and the mass production and assembly are not easy, because the sliders are Nylon or plastic material, the original design is seriously worn out during knocking and loading, and the guide groove is not strong enough, easy to break, the guide slider is easy to get stuck with the bracelet case during assembly, and it is not easy to repair, because there is an air getter under the bayonet, which increases It is difficult to manufacture, the size cannot be guaranteed, and the overall pass rate of the m...

Problems solved by technology

[0004] At present, when the existing hand chain hoists are in use, the assembly structure of the guide sliders is difficult to assemble the sliders, the manufacturing pass rate is low, it is not easy to replace, and the disassembly can only be damaged, the scrap rate is high, and the mass production and assembly are not easy, because the sliders are Nylon or plastic material, the original design is seriously worn out during knocking and loading, and the guide groove is not strong enough, easy to break, the guide slider is easy to get stuck with the bracelet case during assembly, and it is not easy to repair, because there is an air getter under the bayonet, which increases Difficulty in manufacturing, the size cannot be guaranteed, and the overall pass rate of the manufacturing process is not high

[0005] Moreover, when the existing chain hoists are used, most of them are used at fixed angles, which cannot adapt to some special operating environments and affect the work efficiency. Therefore, we propose a chain hoist operation angle adjustable device and Slider assembly structure
