Abstract
The invention relates to a composite transformer cabinet door sealing structure, belonging to the transformer manufacturing technical field. The invention mainly comprises a cabinet body (2) which is provided with a top cover (1), a cabinet door (3) which is provided with a door lock (4) and a rotary handle (11), a doorway (6) for the cabinet body (2) and a door post (5) for the cabinet door (3) which take the structure of an L, a steel plate sandwich core rubber sealing strip (7) which is embedded on the cabinet door (3), an upper lock lever (9) and a lower lock lever (10) which are arrangedinside the cabinet door (3), connected with the door lock (4) and provided with lock lever supports (8), etc. The overall structure design is reasonable; due to the L-shaped structure of the doorway and the door post, the intensity and the rigidity are increased; sealing, dustproof and waterproof effects are improved; the steel plate sandwich core rubber sealing strip has the advantages of superior flexility and elasticity, shape stability, simple and convenient assembly and so on; due to the oblique insertion design of the upper two point form cabinet door lock lever and the lower two point form cabinet door lock lever inside the cabinet door, not only the tightness and the leak tightness for closure of the cabinet door are guaranteed but also the portability of operation is guaranteed.
Description
Technical field
The present invention relates to a kind of sealing structure for combined transformer case door, belong to the manufacturing technology field of transformer.
Background technology
Existing combined transformer power distribution cabinet cabinet door with seal request is because the defective on the design of Sealing Structure, and the undesirable or structure of ubiquity sealing effectiveness is problem such as complexity too.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in designly, have the sealing structure for combined transformer case door of sealing and dustproof waterproof effect.
The present invention is a sealing structure for combined transformer case door, comprises the cabinet of being with top cover, and the cabinet door of band door lock is characterized in that the doorway of cabinet and the L-shaped structure of Men Bianjun of cabinet door, is embedded with steel plate sandwich rubber weather strip on the cabinet door; The inboard of cabinet door also is provided with last locking bar and the following locking bar that links to each other with door lock.
The inboard of described cabinet door also can be provided with supports the locking bar support of going up locking bar and following locking bar.Also can be provided with rotary handle on the described door lock.Gap delta between described cabinet and the cabinet door can be 12 ± 0.5mm.The described angle excursion α that goes up locking bar and following locking bar can be 8 ± 1 °.
The present invention compared with prior art has following outstanding advantage and good effect:
1, the Men Bianjun of the doorway of cabinet and cabinet door is designed to L shaped structure.It is to be mosaic seal that cabinet every limit is designed to L shaped one, the 2nd, and for increasing the intensity and the rigidity of cabinet door.The cabinet doorway is designed to L shaped, its objective is when the gap of water between cabinet door and cabinet enters, and plays barrier effect, and its L shaped limit along the doorway periphery is derived outside the cabinet, prevents that it from entering in the cabinet.
2, the steel plate sandwich rubber weather strip that is adopted has advantages such as good pliability and elasticity, shape stability and simple installation.Particularly the sealing bar can fully guarantee the compactness and the stability that combine with steel plate, makes sealing strip in use not produce distortion deflection and displacement, can fully guarantee sealing.The decrement of choose reasonable and control sealing strip has simultaneously promptly guaranteed the sealing of cabinet door to make the cabinet door open and close light and flexible again.
3, the cabinet door inboard oblique cutting design of two point form cabinet door lock bar has up and down promptly guaranteed compactness and sealing that the cabinet door is closed, has guaranteed the portability of operation again.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention;
Fig. 2 is the structure amplification view of I-I face shown in Figure 1;
Fig. 3 is the structure amplification view of II-II face shown in Figure 1.
Embodiment
The present invention is with the cabinet door 3 of door lock 4 and rotary handle 11 mainly by the cabinet 2 of band top cover 1, and cabinet 2 doorways 6 of L-shaped structure and 3 limits 5 of cabinet door are embedded at the steel plate sandwich rubber weather strip 7 on the cabinet door 3; Place cabinet door 3 inboards link to each other with the door lock 4 last locking bar 9 and following locking bar 10 formations such as grade of shaft bar 8 with lock.
Below in conjunction with concrete assembling of the present invention the present invention is further described:
1, according to steel plate sandwich rubber weather strip 7 decrements, after repetition test, the gap delta between reasonable selection cabinet 2 and the cabinet door 3 is 12 ± 0.5mm, and the angle excursion α of last locking bar 9 and following locking bar 10 is 8 ± 1 °.This gap and angle can guarantee the sealing of cabinet door, make cabinet door operation light and flexible again;
2, on the L type door limit 5 of cabinet door 3 peripheries, inlay steel plate sandwich rubber weather strip 7;
3, on the closed back operation of cabinet door 3 door locks 4 rotary handle 11, the circular arrow direction moves up and down locking bar 9 and following locking bar 10 as shown in Figure 2, straight arrows direction as shown in Figure 2, locking cabinet door 3 guarantees that cabinet 2 and cabinet door 3 reach design gaps δ, guarantees cabinet door 3 sealings.
