Abstract

The utility model relates to the field of mechanical device, in particular to a spring hook which can be easily opened and closed. In a mechanical device, a hook structure is often used for carrying out closing control on a closed door. But in the prior art, an electric control part is needed to be used for realizing the functions of the hook structure. The utility model includes a spring, a prop opening arm, a hook body, a rotating shaft and a top post; the prop opening arm forms right angle connection with the hook body and can rotate along the rotating shaft at the combined location of the prop opening arm and the hook body; the spring and the prop opening arm are fixed by rivets and so on. When the utility model is used, one spring lock in the hook mechanism draws the prop opening arm on the hook; when the top post in a mechanical structure moves to the prop opening arm on the hook, the pull of the spring is overcome to lead the hook body to rotate along the rotating shaft, thus realizing the opening of the hook; when the top post leaves the spring, the prop opening arm and the hook body return to the original position under the effect of the pull of the spring, thus realizing the closing of the hook.

Description

A kind of spring carrier arm

Technical field

The utility model relates to the plant equipment field, relates in particular to a kind of spring carrier arm that can simple and easy switch.

Background technology

In the plant equipment field, often use hook structure, in order to closing door is carried out closing control.But in the prior art, for realizing opening and closing automatically of hook structure needing to use electronic control part, whole like this plant equipment is made complicated, and price is higher.

How to design a kind of existing parts that can utilize plant equipment inside, the latch hook mechanism that can realize opening and closing easily is pendulum technical issues that need to address in face of the science and technology personnel.

The utility model content

The utility model technical issues that need to address have provided a kind of hook that has spring and back down mechanism, are intended to solve the above problems.

In order to solve the problems of the technologies described above, operating principle of the present utility model: have a latch lock drawing in the hitch gear and back down arm on the hook, when fore-set in the frame for movement move on the hook back down arm the time will overcome spring tension, the hook main body is rotated around the axis, realize to open; After fore-set leaves spring, back down arm and hook main body will be under the effect of spring tension homing, realize closing of hook.

The utility model comprises: spring, back down arm, hook main body, rotating shaft, fore-set, described spring and fore-set all are fixed on the mechanical body, and back down arm and meet at right angles with the hook main body and is connected, and can be around backing down arm and the rotating shaft rotation of linking up with the main body junction; Described spring is fixed with the modes such as rivet of backing down arm.

Compared with prior art, the beneficial effects of the utility model are: when using the utility model, the hitch gear open and close is all very easy, need not to increase in addition control assembly.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

As seen from Figure 1: the utility model comprises: spring 1, back down arm 2, hook main body 3, rotating shaft 4, fore-set 5, described spring 1 and fore-set 5 all are fixed on the mechanical body, back down arm 2 and meet at right angles and is connected with hook main body 3, and can be around backing down rotating shaft 4 rotations of arm 2 with hook main body 3 junctions; Described spring 1 is fixed with the modes such as rivet of backing down arm 2.

Claims

1, a kind of spring carrier arm, comprise: spring (1), hook main body (3), it is characterized in that: also comprise back down arm (2),, rotating shaft (4), fore-set (5), described spring (1) and fore-set (5) all are fixed on the mechanical body, back down arm (2) and meet at right angles and is connected with hook main body (3), and can be around backing down rotating shaft (4) rotation of arm (2) with hook main body (3) junction; Described spring (1) is fixed with the modes such as rivet of backing down arm (2).
