Abstract

A kind of automatic sampler, it includes：It is provided with the safety door of opening and the specimen holder with operating portion, using the operating portion specimen holder can be made to insert the inside of the automatic sampler by the opening of the safety door or be pulled out from the inside of the automatic sampler, it is in safety door closure and the specimen holder in the state of inserting, the inside of the automatic sampler is isolated from the outside, in the state of the specimen holder is in the fully inserted, the safety door is immovable relative to the automatic sampler.

Description

Automatic sampler

Technical field

The present invention relates to a kind of automatic sampler.

Background technology

In the prior art, as shown in Figure 1, it is known that a kind of external structure of automatic sampler.Safety as user is prevented Model measure, door 1 is provided with before automatic sampler, will be completely enclosed before automatic sampler, prevent hand etc. from stretching into automatically The inside of injector produces dangerous.Sensor 2 is configured with the door of the inner side of door 1, when door 1 is removed, sensor 2 can be examined Measure and automatic sampler is shut down.After removing door 1, as shown in Fig. 2 specimen holder is inserted and pulled out by hole 3.

But after only door 1 is removed, the specimen holder inside automatic sampler can be pointed to and operated, therefore Operate relatively complicated.

The content of the invention

The present invention proposes a kind of automatic sampler, it is wrapped to improve the convenience of operation and further strengthen security Include：The safety door of opening and the specimen holder with operating portion are provided with, can pass through the specimen holder using the operating portion The opening of the safety door is inserted the inside of the automatic sampler or pulled out from the inside of the automatic sampler, in the peace Air cock is closed and the specimen holder is in the state of insertion, and the inside of the automatic sampler is isolated from the outside, in the sample In the state of product frame is in the fully inserted, the safety door is immovable relative to the automatic sampler.

Described in the inside of the automatic sampler of the present invention and outside " isolation " refer to that the human bodies such as hand can not stretch into The inside of automatic sampler, the completely isolated state such as vacuum is not implied that.

The operating portion, which is preferably at least, has a protuberance, and the protuberance is from the operating portion to the safety door Direction protrude, prevent the safety door from being moved relative to the automatic sampler.The protuberance can also be with the operation Portion is integrally formed.

The automatic sampler is preferably that security gate sensor, the safety are provided with the door on the inside of the safety door Door sensor can make the automatic sampler shut down when detecting that the safety door is removed.

The automatic sampler is preferably that the specimen holder is provided with specimen holder sensor, and the specimen holder sensor exists Detect that the specimen holder can make the automatic sampler shut down when pulled.

Using the automatic sampler of structure of the present invention, due to can directly be drawn in the case where not removing safety door Go out specimen holder, therefore operating procedure can be reduced, make operation more convenient.

Also, due to security gate sensor and specimen holder sensor this dual sensor, pull out specimen holder and When removing safety door, sensor can detect, so that equipment shuts down, realize double safety.

In addition, in the state of specimen holder is in the fully inserted, safety door is immovable relative to the automatic sampler, Further increase security during operation.

Embodiment

3 and Fig. 4 illustrates to the automatic sampler of the preferred embodiment of the present invention referring to the drawings.

Fig. 3 is that the specimen holder of the automatic sampler of embodiments of the present invention is in the schematic diagram of pull-out state.Fig. 4 is this The specimen holder of the automatic sampler of the embodiment of invention is in the fully inserted the schematic diagram of state.

As shown in figure 3, automatic sampler includes safety door 4 and the specimen holder 5 with handle 6 (example of operating portion), Safety door 4 is provided with rectangular opening 7, and operator can be inserted specimen holder 5 by the opening 7 of safety door 4 using handle 6 The inside of the automatic sampler.

As the preferred embodiments of the present invention, as shown in figure 3, block handle 6 has the protrusion being integrally formed with handle 6 Portion 8.The height of protuberance 8 and the height of handle 6 keep suitable, from the appearance from the point of view of be integrally formed.Protuberance 8 from handle 6 to The direction of safety door 4 protrudes, and so as to block safety door 4 in the state of specimen holder 5 is in the fully inserted, prevents the phase of safety door 4 Moved for automatic sampler.

But the embodiment of protuberance 8 is not limited to described above, the shape of protuberance can variation.It is prominent Portion can be relative to the independent part of handle 6, be attached on handle 6.Handle 6 can also have one or more prominent Portion, and position of the protuberance on handle 6 can arbitrarily be set, if what protuberance can be in the fully inserted in specimen holder 5 Cause that safety door 4 is immovable relative to automatic sampler under state.

As shown in figure 4, in the state of specimen holder 5 is in the fully inserted, because the protuberance 8 of handle 6 blocks safety door 4, and make safety door 4 immovable relative to Autosampler, the inside of the automatic sampler is isolated from the outside.Here every From the inside for being meant that to prevent the human body parts such as hand from stretching into the automatic sampler, serve the work of safeguard protection With.

When operator is intended to operate the sample on specimen holder 5, operator need not remove safety door 4, only need profit Specimen holder 5 is pulled out from the inside of the automatic sampler by the opening 7 of safety door 4 with handle 6, improves the convenient of operation Property.

Specimen holder 5 is for example provided integrally with specimen holder sensor (not shown), and specimen holder sensor detects specimen holder 5 When pulled, the automatic sampler is made to shut down, the operator provided whereby for automatic sampler first protects again.

Security gate sensor 9 is also equipped with the door of the inner side of safety door 4, security gate sensor 9 is detecting the quilt of safety door 4 Automatic sampler can be made to shut down when removing, so, in the case of specimen holder faulty sensor, security gate sensor 9 It can provide and be protected again for the second of operator.

Although hereinbefore the preferred embodiment of the present invention is illustrated, it will be appreciated that these are examples of the present invention The embodiment shown, and should not be regarded as limited embodiment.Increase, delete, replace, and other modifications can not take off Carried out in the case of from the scope of the invention.Therefore, the present invention should not be regarded as being limited by described above, but will by right Book is asked to be limited.
