Description

Long tube type door handle with locking and automatic unlocking functions

Technical Field

The utility model relates to an install the handle on the door leaf, concretely relates to long cast door handle of area locking and automatic unblock function.

Background

In the prior art, a door of some devices is often provided with a door latch for locking the door to maintain the closed state of the door. 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, the utility model designs a take locking and automatic unblock function's long cast door handle.

Disclosure of Invention

The utility model aims at providing a long cast type door handle of area locking and automatic unblock function, do not need manual additional to detain after closing the door, also need not manual the release knocker, reduce the action of personnel's switch door, improve operating efficiency.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the long-tube door handle with the locking and automatic unlocking functions comprises a hinge fixed end, a hinge movable upper end, a hinge movable lower end, an upper hook, a lower hook, a fixed lock hook, a holding rod and a spring piece, wherein the hinge movable upper end and the hinge movable lower end are respectively connected with the upper end and the lower end of the holding rod, the hinge movable upper end and the hinge movable lower end are hinged with the hinge fixed end, the hinge fixed end is fixed at the upper end and the lower end of the side edge of a vacuum box door, the upper hook is arranged on the outer side of the hinge movable upper end, the lower hook is arranged on the outer side of the hinge movable lower end, the upper hook and the lower hook are respectively fastened with the fixed lock.

The utility model discloses following beneficial effect has:

1. the utility model discloses when closing the door, lift on the door handle and can hang the knocker and keep the door closed state.

2. The utility model is used for on the vacuum chamber door, when the vacuum chamber forms the vacuum, the vacuum chamber door compresses tightly the sealing strip automatically under the effect of box external pressure, and the couple breaks away from with fixed locking hook, and the effort disappears, and the holding rod gets back to the initial position under the effect of spring leaf, drives the couple and outwards moves upward, realizes automatic tripping. The vacuum box door has the advantage that after the vacuum box body is separated from vacuum, the vacuum box door can be automatically opened without other operations.

3. 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.

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

5. The utility model discloses be not restricted to and be used in the door, also can be used to in the similar application.

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 4, the following technical solutions are adopted in the present embodiment: the long tube type door handle with the locking and automatic unlocking functions comprises a hinge fixed end 1, a hinge movable upper end 2a, a hinge movable lower end 2b, an upper hook 3a, a lower hook 3b, a fixed locking hook 4, a holding rod 5 and a spring piece 6, wherein the hinge movable upper end 2a and the hinge movable lower end 2b are respectively connected with the upper end and the lower end of the holding rod 5, the hinge movable upper end 2a is hinged to the hinge fixed end 1, the hinge fixed end 1 is fixed at the upper end and the lower end of the side edge of a vacuum chamber door, the upper hook 3a is arranged on the outer side of the hinge movable upper end 2a, the lower hook 3b is arranged on the outer side of the hinge movable lower end 2b, the upper hook 3a and the lower hook 3b are respectively buckled with the fixed locking hook 4, and the upper hook 3a and the lower hook 3.

When the handle is pushed towards the door closing direction in the embodiment, the hook is buckled with the fixed locking hook 4 to keep the door closed. This handle is used for on the vacuum chamber door, and when vacuum incasement formed the vacuum, the vacuum chamber door compressed tightly the sealing strip automatically under the box external pressure effect, and the couple breaks away from with fixed locking hook, and the interaction force disappears, and the holding rod is kick-backed in the effect of spring leaf 6, drives the couple and deviates from the latch hook, realizes automatic tripping. The handle of this embodiment may be used on both sides as shown, or may be used on one side (on a hinged door).

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.
