Description

Speed-variable operation linkage door lock mechanism for prefabricated cabin type box

Technical Field

The utility model belongs to the technical field of prefabricated cabin transformer, concretely relates to prefabricated cabin type case variable-speed operation linkage lock mechanism.

Background

With the progress of new energy photovoltaic, energy storage technology and integration technology, the overall dimensions of the prefabricated cabin and the box body of the energy storage cabin are wider and wider, and the weight of the cabin door (with a double-layer heat insulation layer) is larger and larger.

The side door of the box body is often in a door bolt structure, an operator is required to insert (close) or pull (open) the upper bolt and the lower bolt respectively, the operation is time-consuming and labor-consuming, and in a project site, the operation is not only low in safety, but also can improve the power failure time for repairing faults; in addition, when realizing through the bolt that the limit door is closed tightly, the sealing strip on the door compresses tightly the quality and can't guarantee to can reduce the protection level requirement of box.

SUMMERY OF THE UTILITY MODEL

The design purpose is as follows: for avoiding not enough among the background art, design one kind not only can improve the operating safety nature, can reduce the power off time who overhauls the trouble moreover, can ensure the box protection level simultaneously one kind prefabricated cabin type case variable-speed operation linkage lock mechanism.

The design scheme is as follows: the design purpose is realized.

1. One side of the limit door in the chamber door is articulated with the door frame, the opposite side is articulated with well door in the chamber door, the upper portion and the lower part of limit door medial surface are equipped with an elasticity striking lock respectively, the striking face of the spring bolt in the elasticity striking lock is the design of arcwall face, is one of the technical characteristics of the utility model. The purpose of this design is: one side of a side door in the box door is hinged with the door frame, the other side of the side door is hinged with a middle door in the box door, the upper part and the lower part of the inner side surface of the side door are respectively provided with an elastic impact lock, and the impact surface of a lock tongue in the elastic impact lock is an arc-shaped surface, so that the side door can be automatically locked only by pushing the door when the door is closed, the door closing efficiency is improved, and the protection grade requirement of a box body shell is ensured.

2. The middle part of limit door medial surface is equipped with the wane through the pivot, the both sides end of wane is respectively through the end-to-end connection of a linkage and the spring bolt that corresponds, and the spring bolt in two elasticity striking locks returns simultaneously when the wane revolutes the rotation of axes under the exogenic action and the elastomer in two elasticity striking locks all is in compression state or all is in the design of tensile state, is the utility model discloses a two technical characteristics are. The purpose of this design is: the middle part of limit door medial surface is equipped with the wane through the pivot, the both sides end of wane is respectively through the end-to-end connection of a linkage and the spring bolt that corresponds, the spring bolt in two elasticity striking locks returns simultaneously when the wane revolutes the rotation of axes under the exogenic action and the elastomer in two elasticity striking locks all is in compression state or all is in tensile state, like this when opening the door, only need the little handle of manual operation unblock, just can open the limit door fast and carry out the troubleshooting operation, because the improvement of the efficiency of opening the door, the power off time of troubleshooting is shortened like this, the power of unblock operation is also little in addition, use comparatively labour saving and time saving.

3. The design that the medial surface of limit door is equipped with the sealing strip all around is the utility model discloses a three technical characteristic. The purpose of this design is: when the automatic locking limit door, the sealing strip that is located the limit door medial surface is compressed tightly on the door by the "precompression" function of elasticity striking lock to make the door realize sealed, with the barrier propterty of ensureing the door, and then guarantee the protection level requirement of box.

The technical scheme is as follows: the utility model provides a prefabricated cabin type case variable-speed operation linkage lock mechanism, includes prefabricated cabin box, be equipped with two chamber doors on the door frame of prefabricated cabin box, one side of limit door in the chamber door is articulated with the door frame, the opposite side is articulated with well door in the chamber door, the upper portion and the lower part of limit door medial surface are equipped with an elastic impact lock respectively, the striking face of the spring bolt in the elastic impact lock is the arcwall face.

Compared with the prior art, the utility model, firstly, when the door is closed, the prefabricated cabin molding box becomes the quick operation linkage door lock mechanism, only needs to push the door, can lock the side door automatically, thus improving the door closing efficiency; secondly, when the door of the prefabricated cabin type box is quickly operated and the linked door lock mechanism is opened, only the small handle is operated by hand to quickly open the side door for troubleshooting operation, the power failure time of troubleshooting is shortened due to the improvement of the door opening efficiency, in addition, the unlocking operation force is small, and time and labor are saved; thirdly, when the prefabricated cabin type box becomes fast operation linkage door lock mechanism automatically locks the side door, the door can be sealed, and therefore the protection level requirement of the box body is guaranteed.
