Abstract

The utility model discloses a locking mechanism of a fixation arm and a linkage rack of a draw arm hook, characterized in that the locking mechanism comprises left, right locking hooks (2) connected together by a rotation pin axle (3), wherein the rotation pin axle (3) is connected with the fixation arm (5) by an axle sleeve and two locking hooks (2) rotate by the rotation pin axle (3) and the upper ends of the locking hooks (2) are respectively connected with tension springs (1) and the lower ends are respectively corresponding with a locking piece(4) and the locking piece (4) is rigidly coupled with a linkage rack (6). The mechanism is a visual, eudipleural locking mechanism of the fixation arm and the linkage rack of the draw arm hook with stable work performance and high safe performance.

Description

A kind of fixed arm of torque arm hook and interlock frame catch gear

Technical field:

The utility model relates to assembling system technical field on the torque arm hook, is a kind of later-model torque arm hook fixed arm and interlock frame catch gear concretely, is particularly useful for assembling system in the torque arm.

Background technology:

At present, assembling system fixed arm and interlock frame catch gear on the torque arm car that uses, be bottom bolt-type catch gear, this version ubiquity, this motion of mechanism state be cannot see in the dress outside in torque arm, in handling process, discontinuity, the stability when influencing work, version is single, danger coefficient is big, and safety performance is low.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, but fixed arm that a kind of direct viewing type, symmetrical torque arm hook be provided and interlock frame catch gear, the fixed arm that mainly solves existing torque arm hook and interlock frame catch gear problems such as unstable properties, safety performance be low at work.

In order to achieve the above object, the utility model is achieved in that a kind of fixed arm and interlock frame catch gear of torque arm hook, its special character be it comprise about two locking bails, two locking bails link together by rotary pin shaft, rotary pin shaft links together by axle sleeve and fixed arm, and two locking bails rotate by rotary pin shaft, and the upper end of two locking bails connects extension spring respectively, the lower end is corresponding with lock dog respectively, and lock dog is fixed on the interlock frame; The catch gear left-right symmetric, but and in the process of motion direct viewing to state of kinematic motion.

Compared with the prior art the fixed arm of a kind of torque arm hook described in the utility model has following good effect with interlock frame catch gear: but 1, torque arm is hooked in the process of motion direct viewing to state of kinematic motion, in the process of motion stressed evenly; 2, catch gear left-right symmetric, the safety performance height; 3, installation, easy to maintenance.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the birds-eye view of the mode of operation of Fig. 1.

Among the figure: the 1-extension spring 2-locking bail 3-rotary pin shaft 4-lock dog 5-fixed arm 6-frame that links

The specific embodiment:

In order to understand better and to implement, provide the fixed arm and interlock frame catch gear that specific embodiment describes a kind of torque arm hook of the utility model in detail below in conjunction with accompanying drawing.

Embodiment one, referring to Fig. 1, with about two locking bails 2 link together by rotary pin shaft 3, rotary pin shaft 3 links together by axle sleeve and fixed arm 5, two locking bails 2 are by rotary pin shaft 3 rotations, upper end at two locking bails 2 is installed extension spring 1 respectively, and its lower end is respectively with to be welded on the lock dog 4 of interlock on the frame 6 corresponding.

The fixed arm of a kind of torque arm hook described in the utility model and interlock frame catch gear, its principle of work (see figure 2), during work, promote locking bail by the telescopic boom in the fixed arm, locking bail rotates by rotary pin shaft, thereby locking bail is separated with lock dog, realize the moved apart of fixed arm and interlock frame, when telescopic boom left, locking bail combined with lock dog is automatic under the effect of extension spring, thereby guaranteed in the process of work stressed even, safe and reliable.

Claims

1. the fixed arm of a torque arm hook and interlock frame catch gear, it is characterized in that it comprise about two locking bails (2), two locking bails (2) link together by rotary pin shaft (3), rotary pin shaft (3) links together by axle sleeve and fixed arm (5), two locking bails (2) are by rotary pin shaft (3) rotation, the upper end of two locking bails (2) connects extension spring (1) respectively, and the lower end is corresponding with lock dog (4) respectively, and lock dog (4) is fixed on the interlock frame (6).
