作が一層容易になる。As a result, the thermostat has a temperature of 85 ° C., for example.
Even when operated under high temperature and high humidity conditions with a relative humidity of 85% and the door is opened and closed immediately for loading and unloading of the sample and internal inspection, the expanded air that enters the chamber escapes from the gap t. Therefore, the single-stage lock can be easily applied without generating an internal pressure. Further, the temporary lock position can be held without the door bouncing. When the temporary lock is performed in this manner, it is not necessary to bring the lock to the complete lock at one time, and since no internal pressure is generated, the door does not have to be closed with a very strong force. Therefore, the reaction torque at the time of locking is reduced, and the operation of closing the door is further facilitated.

When the handle 1 is turned in a counterclockwise direction, the rotation is immediately transmitted to the end shaft 4 via the shaft 2 and the pin 7, and at the same time, the pawl 3 is rotated to release the lock. be able to. That is, even when a two-stage lock claw or a buffer mechanism is provided as in the present invention, the door unlock operation can be performed in exactly the same manner as a conventional ordinary lock device. The door can be opened by pulling the handle 1 as shown in FIG.

In this way, the ease of operation by reducing the pressing force associated with the two-stage closing method and the comfort of operation by relaxing the reaction torque at the time of locking can be obtained at the same time, making it extremely light and operable. It can be a good door lock device. However, a door lock device employing only one of these structures is also possible. Even in that case, the comfort and ease of operation are sufficiently improved as compared with the conventional device.

る。As described above, according to the present invention, according to the first aspect of the present invention, the first concave portion and the second concave portion are arranged in the order in which the claw member engages with the convex member of the main body when the door is closed. When the door is closed, the first concave portion is first engaged with the convex member, and the door can be temporarily locked. Since this temporary lock position is a position where the door is not completely closed, by appropriately determining the correlation between the size of the packing and the like provided on the mating surface of the door and the position of the first concave portion, the provisional lock position is determined. Appropriate spacing can be provided between the packings. Thus, even if the inside of the main body is in a high temperature environment higher than room temperature, the air that has entered the inside when the door is opened and has expanded can be released, and an increase in the internal pressure can be prevented. As a result, a strong pressing force is not required when closing the door. In addition, the door can be kept in the slightly open state by the temporary lock, so that the transition to the complete lock becomes easy.

して操作の快適性を確保することができる。When the door is further closed from the temporarily locked state, the second concave portion is engaged with the convex member, and the door can be completely locked. At this time, since the door further advances in the direction in which the door closes, it is possible to compress the packing or the like to form a seal, thereby making the inside of the main body portion airtight. In this case, since the internal air is released by the temporary lock and the internal pressure is released, a large pressing force is not required at the time of the complete lock. As described above, by adopting such a two-stage locking method in a special purpose device such as an environmental device, the operating force at the time of closing the door is reduced, the reaction torque of the claw member at the time of locking is reduced, and , The comfort of operation can be ensured.

Since it is configured to urge the locking member in a direction opposite to one direction, the locking member is pressed against one side of the groove by the urging force,
An interval can be provided between the groove and the other side. With this configuration, even when the claw member strikes the convex member of the main body portion and rotates impactfully when the door is closed, the rotational force is transmitted to the shaft and the handle via the biasing member, and the reaction torque transmitted to the hand is reduced. Significantly eased. As a result, the user does not feel discomfort when the door is closed, and the operational comfort can be ensured.
