Description

Isolator lock

Technical Field

This application belongs to entrance guard's equipment technical field, relates to an isolator lock particularly.

Background

With the rapid development of the Chinese pharmaceutical industry, the requirement on the production environment of the medicine in China is more and more strict. Isolators are important production equipment in pharmaceutical plants during production, and therefore in practice there are strict monitoring requirements for the opening and closing of the glass doors of the isolators. Existing isolator door locks generally employ a mechanical rotary structure. The problems with this mechanism are: 1. the open-close state of the glass door cannot be monitored; 2. when the door is closed, the door needs to be locked by manually rotating the handle. Therefore, it is an objective of the present invention to develop a new isolator door lock structure to overcome the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model provides an isolator lock can realize the switch monitoring to the glass door on the isolator in the drug manufacturing process, need artifically die the door lock when having avoided closing the door, has simplified the operation.

The technical scheme is as follows:

an isolator door lock, comprising: a lock case; the handle, the bolt, the lock seat and the spring; a cavity is arranged in the lock shell, an operation hole communicated with the cavity is formed in the front wall of the lock shell, and a locking hole communicated with the cavity is formed in the side wall of the lock shell; one end of the spring is fixed on the inner wall of the cavity, and the other end of the spring is fixed with the handle into a whole; the handle is exposed in the operation hole; one end of the lock tongue is fixed with the handle, and the other end of the lock tongue is hidden in the lock shell when the spring is compressed and extends out of the outer side of the lock shell through the locking hole when the spring is extended; and the lock seat is provided with a lock channel corresponding to the locking hole.

By adopting the technical scheme:

when the spring is in an uncompressed state, the bolt extends out of the outer side of the lock shell. When the glass door of the isolator is closed, the glass door is pushed to enable the lock shell to lean against the lock seat, when the spring bolt contacts the lock seat, the spring bolt retracts into the lock shell under the action of force, and meanwhile, the spring compresses. When the glass door moves to the door closing station, the locking hole is opposite to the lock channel, the spring resets to drive the lock tongue to reset, and the head of the lock tongue is inserted into the lock channel to realize automatic door locking. When the glass door of the isolator needs to be opened, the person pulls the handle back because the bolt and the handle are fixed together. The bolt 3 is separated from the lock seat 4, and the glass door is opened.

Preferably, in the isolator door lock, the isolator door lock further includes: the spring bolt is towards lock seat one side and is the slope structure.

By adopting the technical scheme: when the lock shell leans against the lock seat and the bolt extending part contacts the lock seat, the contact surface of the bolt and the lock seat is reduced, and meanwhile, force extending towards the direction of the spring is generated on the surface of the bolt, so that the process of retracting the bolt into the lock shell is smoother.

More preferably, the isolator door lock further includes: a photosensor; the photoelectric sensor is fixed in the lock seat and used for sensing a lock tongue extending into the lock channel.

By adopting the technical scheme: the photoelectric sensor is used for realizing the right and further realizing the monitoring of the opening and closing state of the glass door on the isolator.

More preferably, the isolator door lock further includes: a non-slip mat; the anti-skid pad is arranged on one side of the lock shell facing the door glass.

By adopting the technical scheme: the lock case is separated from the glass by a non-slip gasket.

Compared with the prior art, the technical scheme of the application is simple in structure and easy to realize. Enables the glass door switch of the isolator to be monitored during the pharmaceutical manufacturing process. Through set up spring bolt and spring at the isolator lock, need not manual operation and can die the door lock when closing the door, simplified the operation.

Drawings

The present application will now be described in further detail with reference to the following detailed description and accompanying drawings:

FIG. 1 is a schematic view of the internal structure of the present application, with the non-slip mat omitted;

FIG. 2 is a schematic illustration of an explosive structure of the present application;

the corresponding component names in the drawings are as follows:

1. a lock case; 2. a handle; 3. a latch bolt; 4. a lock seat; 5. a spring; 6. a photosensor; 8. an operation hole; 9. a locking hole; 10. and (6) locking the channel.

Detailed Description

In order to more clearly illustrate the technical solutions of the present application, the following will be further described with reference to various embodiments.

As shown in FIGS. 1-2, example 1 of the present invention:

an isolator door lock, comprising: a lock case 1; handle 2, spring bolt 3, lock seat 4, spring 5, photoelectric sensor 6 and slipmat.

A cavity is arranged in the lock shell 1, an operation hole 8 communicated with the cavity is formed in the front wall of the lock shell 1, and a locking hole 9 communicated with the cavity is formed in the side wall of the lock shell; one end of the spring 5 is fixed on the inner wall of the cavity, and the other end of the spring is fixed with the handle 2 into a whole; the handle 2 is exposed in the operation hole 8; one end of the bolt 3 is fixed with the handle 2, and the other end is hidden in the lock shell 1 when the spring 5 is compressed and extends out of the lock shell 1 through the locking hole 9 when the spring 5 is extended; the lock seat 4 is provided with a lock channel 10 corresponding to the locking hole 9. In this example: the side of the lock tongue 3 facing the lock seat 4 is in a slope structure. The photoelectric sensor 6 is fixed in the lock seat 4 and used for sensing the bolt 3 extending into the lock channel. The anti-skid pad is arranged on one side of the lock shell 1 facing the door glass.

In practice, the working process is as follows:

when the spring 5 is in an uncompressed state, the bolt 3 extends out of the outer side of the lock shell 1. When the glass door of isolator is closed, promote glass door and make lock shell 1 lean on to lock seat 4, when spring bolt 3 contacted lock seat 4, spring bolt 3 contracts in the lock shell 1 under the effect of force, and spring 5 compresses simultaneously. When the glass door moves to the door closing station, the locking hole is opposite to the lock channel, the spring 5 resets to drive the bolt 3 to reset, and the head of the bolt 3 is inserted into the lock channel to realize automatic door locking. Meanwhile, the photoelectric sensor 6 monitors that the bolt 3 reaches the inside of the lock seat 4 to complete door locking. When the glass door of the isolator needs to be opened, a person pulls the handle 2 backwards because the bolt 3 and the handle 2 are fixed together. The bolt 3 is separated from the lock seat 4, and the glass door is opened. Meanwhile, the photoelectric sensor 6 detects that the bolt 3 leaves the lock seat 4 and the glass door is unlocked.

The above description is only for the specific embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application are intended to be covered by the scope of the present application. The protection scope of the present application shall be subject to the protection scope of the claims.
