Abstract
The utility model discloses an explosion-proof electric appliance structure. The explosion-proof electric appliance structure comprises a flame-proof body and a flame-proof cover. A flanging is arranged outside the upper end of the flame-proof body, the cover edge of the flame-proof cover matches the flanging of the flame-proof body, and the space between the flame-proof cover and the bottom of the flame-proof body forms a flame-proof cavity. The upper edge of the flanging of the flame-proof body is a planar flame-proof surface, and the flame-proof body is equipped with a seam allowance flame-proof surface from the upper end of the flame-proof body to the inner wall of a baffle; the seam allowance flame-proof surface is a conical surface which is not vertical with a seam allowance, and the seam allowance flame-proof surface is not vertical with the planar flame-proof surface. According to the utility model, the vertical flame-proof surface of the conventional seam allowance is processed into a tight cooperation surface of a specific format, the processed conical flame-proof surfaces cooperate more tightly, are easy to disassemble, and accord with the flame-proof standards and requirements, so that the problems that the installation and maintenance of the seam allowance flame-proof surface are difficult are solved effectively.
Description
Technical field
The utility model relates generally to explosion-proof field, relates in particular to a kind of structure of explosion-proof electric apparatus.
Background technology
At present, seam explosion suppresion surface (as common II C level station-service explosion-proof electric apparatus) for explosion-proof electric apparatus, according to national anti-explosion product standard-required, the flame proof gap must be less than 0.15mm, cooperation processing and the installation difficulty on flame proof plane are all very little, but cooperate circular seam explosion suppresion surface closely, in processing, install, in the process of safeguarding, the distortion slightly of cavity all can cause the assembling difficulty of body and lid, cooperates when explosion suppresion surface needs repairing maintenance after the long-term use of product closely, dismantles also difficult unusually, though a lot of products stay when design and eject screw, but because the efficient that ejects is low, many times the workman forces beating energetically, violence dismounting and installing.Its local flame proof gap can't guarantee all to meet the requirements of the standard under the violence operation when serious, causes explosion-proof inefficacy.
The utility model content
The utility model is the deficiency that remedies prior art, a kind of structure of explosion-proof electric apparatus is provided, both solved the dismounting that may occur in the installing/dismounting process and difficulty is installed, the flame proof gap that can satisfy standard-required again greatly facilitates workman's operation and the maintenance of product.
The technical solution adopted in the utility model is:
A kind of structure of explosion-proof electric apparatus, include flame proof body, flame proof lid, be provided with flange outside the upper end of flame proof body, the lid of flame proof lid is along cooperating with the flange of flame proof body, space between the bottom of flame proof lid and flame proof body constitutes explosion-proof chamber, and the upper edge of the flange of described flame proof body is plane flameproof surface, and the inwall to baffle plate is the seam explosion suppresion surface to the flame proof body from last, it is characterized in that: described seam explosion suppresion surface adopts the conical surface of non-perpendicular seam, seam explosion suppresion surface and plane flameproof surface out of plumb.
Seam explosion suppresion surface of the present utility model has certain tapering on the whole, and certain gradient is arranged on the microcosmic.
The utility model has the advantages that:
The utility model is processed into the vertical explosion suppresion surface of traditional seam in the face that closely cooperates of particular form, taper explosion suppresion surface after the processing cooperates tightr, and be easy to dismounting, and meet the flame proof standard-required, efficiently solve the problem of the installation and maintenance difficulty of seam explosion suppresion surface.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of macroscopical cone match face in B district among Fig. 1.
Fig. 3 is the enlarged drawing of the trapezoidal mating surface of microcosmic in C district among Fig. 1.
Embodiment
As shown in Figure 1, a kind of structure of explosion-proof electric apparatus, include flame proof body 1, flame proof lid 2, be provided with flange outside the upper end of flame proof body 1, the lid of flame proof lid 2 is along cooperating with the flange of flame proof body, and the space between the bottom of flame proof lid 2 and flame proof body 1 constitutes explosion-proof chamber 3, the upper edge of the flange of flame proof body 1 is plane flameproof surface 4, inwall to baffle plate is seam explosion suppresion surface 5 to flame proof body 1 from last, and seam explosion suppresion surface 5 adopts the conical surface, seam explosion suppresion surface 5 and plane flameproof surface 4 out of plumb of non-perpendicular seam.
Seam explosion suppresion surface 5 has certain tapering on the whole, and certain gradient is arranged on the microcosmic.
Among Fig. 2, its seam section and plane flameproof surface are the tapering greater than 90 °, and concrete angle is determined according to the size of explosion-proof chamber and the length of explosion suppresion surface.Its fit clearance can be controlled in the 0.05mm.
Among Fig. 3, from microcosmic, mating surface still is made of in echelon step by step vertical mating surface.
