Abstract

The utility model discloses a hook component for a lever block, comprising a lower hook frame which is connected with a hoisting chain, a hook which is arranged on the lower hook frame and a Carcel plate which is arranged on the hook; wherein, two grooves are respectively opened at the left end and the right end of the joint between the hook and the Carcel plate. As the Carcel plate is closely assorted with the grooves on the hook, the utility model can solve the problem that the Carcel plate is not tightly assorted with the hook, and the utility model is simple in structure and safe is use.

Description

The hook assembly of Lever Blocks

Technical field

The utility model relates to a kind of hook assembly of Lever Blocks, belongs to hand-held design hand crane tool.

Background technology

The opening part of the suspension hook of common in the market Lever Blocks is provided with a Carcel plate, the effect of Carcel plate is when Lever Blocks is worked, prevent that the object of being sling from coming off from suspension hook, thereby cause danger, generally also be provided with returning spring on the Carcel plate, closely cooperate with assurance and suspension hook, but because Carcel plate period of service is long, wearing and tearing that cause and cause with suspension hook and can't closely cooperate, thus bring some use and safety on defective.

The utility model content

At the defective that prior art exists, the purpose of this utility model is to provide the hook assembly of a kind of easy to use, safety, abrasion resistant Lever Blocks.

For achieving the above object, the technical scheme that the utility model is taked is, a kind of hook assembly of Lever Blocks, comprise the following hook housing that links to each other with hoisting chain, be installed in down the suspension hook on the hook housing, the Carcel plate also is installed on suspension hook, it is characterized in that: the two ends, the left and right sides in suspension hook and Carcel plate junction all have the twice groove, and the groove on Carcel plate and the suspension hook is suitable.

The utility model further is set to: the Carcel plate is set to V-type, and the intermediate projections portion that the twice groove forms on the depressed part of V-type Carcel plate and the suspension hook is complementary, and closely cooperates thereby form.So just can solve Yin Kasuo plate wearing and tearing and bring cooperate untight problem with suspension hook, simple in structure, safe in utilization.Apparently, on the suspension hook of last hook housing, can adopt and the identical setting of following hook housing, also can obtain identical effect.

Hoisting chain is revoked with jam nut with the general employing in following hook housing junction and is connected, in the utility model, two ends at jam nut are provided with projection, so just prevented the loosening of jam nut, thereby the hoisting chain that causes are connected loosening problem with following hook housing.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
