Description

Novel hanging buckle

Technical Field

The utility model relates to an install hanging on door frame and door leaf and detain, concretely relates to novel hang knot, mainly used vacuum chamber door's novel hanging knot.

Background

Generally, after the door is closed, the door lock and the door lock are manually locked to keep the closed state of the door. When the door is opened, the operator is required to manually release the door catch. Sometimes, these two actions reduce the efficiency of the personnel operating the equipment.

To sum up, this the utility model designs a novel hanging of operating efficiency is detained has been improved.

Disclosure of Invention

The utility model aims at providing a novel hang and detain, need not manual with detaining after closing the door, also need not manual the release knocker, reduce the action of personnel's switch door, improve operating efficiency to exist on prior art.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a novel hang and detain, includes and hangs and detain body, pendulum rod base, swing peg, pendulum shaft, torsional spring, screw, C shape jump ring and roller, hangs and detains body outward flange and roller roll cooperation, and the roller passes through C shape jump ring setting in swing peg one end, and the swing peg other end passes through the pendulum shaft and links to each other with the pendulum rod base, has cup jointed the torsional spring on the pendulum shaft, and the screw passes the pendulum rod base and links to each other with the pendulum shaft bottom.

Preferably, two pairs of surfaces on the periphery of the hanging buckle body are respectively a positive inclined surface and a negative inclined surface.

Preferably, the outer periphery of the hanging buckle body is of a curve structure.

Preferably, the hanging buckle body and the swinging hanging rod are provided with long holes which can be used for adjusting the relative position of the hanging buckle.

The swing hanging rod of the utility model is the initial position when the torsion spring is not stressed, and can swing up and down with the initial position as the starting point under the action of external force; after the external force is removed, the swinging hanging rod is restored to the initial position under the action of the torsion spring.

The utility model discloses following beneficial effect has:

1. the utility model discloses a hang and do not need the action of hanging the knocker when detaining the door.

2. After the vacuum operation is finished, the door is automatically in a tripping state, and the action of the door buckle is not required to be released when the door is opened. (the utility model is used for on the vacuum chamber door, when vacuum chamber in formation vacuum, the vacuum chamber door compresses tightly the sealing strip automatically under the box external pressure effect, hangs to detain and moves left and cross the B point, realizes tripping under the torsional spring effect, such advantage is that after the vacuum chamber body breaks away from the vacuum, the vacuum chamber door does not need other operations can open automatically.)

3. Reduce the action of operating personnel, improve the operation continuity, improve operating efficiency.

4. Not limited to use on doors, but may be used in similar applications.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 to 9, the following technical solutions are adopted in the present embodiment: the utility model provides a novel hang and detain, includes to hang and detain body 1, pendulum rod base 2, swing peg 3, pendulum shaft 4, torsional spring 5, screw 6, C shape jump ring 7 and roller 8, hangs and detains 1 outward flange of body and roller 8 roll cooperation, and roller 8 sets up in 3 one ends of swing peg through C shape jump ring 7, and the 3 other ends of swing peg link to each other with pendulum rod base 2 through pendulum shaft 4, has cup jointed torsional spring 5 on the pendulum shaft 4, and screw 6 passes pendulum rod base 2 and links to each other with pendulum shaft 4 bottom.

It is worth noting that two opposite surfaces of the periphery of the hanging buckle body 1 are respectively a positive inclined surface 1-1 and a negative inclined surface 1-2.

It is noted that the outer periphery of the buckle body 1 is of a curved structure.

In addition, hang and detain body 1 and swing peg 3 on all be provided with the slot hole, can be used to adjust and hang and detain relative position.

The working principle of the specific embodiment is as follows: as shown in figure 5, in the relative position (1), the roller at the front end of the swing hanging rod just contacts the right inclined surface of the hanging buckle. At the moment, the torsion spring is in an initial state, the swinging hanging rod is horizontal, and the swinging rod is not stressed. In the relative position (2) as shown in fig. 6, the roller at the front end of the swing hanging rod moves along the positive inclined surface until the roller crosses the top of the hanging buckle, and then the roller continues to move leftwards along the top edge under the action of the swing rod torsion spring. As shown in figure 7, in the relative position (3), after the roller at the front end of the swing rod passes over the point A at the top of the hanging buckle, the roller is hung and buckled at the groove between the points A, B under the action of the torsion spring of the swing rod. This is the end of closing the door. As shown in fig. 8, at the relative position (4), the door moves forward with the swing rod under the action of a larger external force, such as the attraction force to the door after the vacuum pumping in the box body, so that the roller at the front end of the swing rod goes over the point B at the top of the hanging buckle, further swings downward under the action of the torsion spring 5, and finally stops at the horizontal position. This state is ready for opening the door. As shown in fig. 9, in the relative position (5), when the door is opened, the roller at the front end of the swing rod swings downwards under the action of the reverse inclined surface until the roller crosses the bottom of the hanging buckle, then the roller continuously moves rightwards along the bottom edge until the roller is separated from the bottom edge, and the roller restores to the original shape under the action of the torsion spring. At this moment, the whole door closing and opening process is finished.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
