Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment of the utility model provides an in the attached drawing: the different types of hatching in the figures are not given the national standards, do not require the material of the elements, and distinguish between cross-sectional views of the elements in the figures.
Referring to fig. 1-2, a switch cabinet with a pressure relief protection structure includes a cabinet body 1 and a top cover 2 fixedly mounted on the top of the cabinet body 1, a fixing sleeve 3 equidistantly sleeved on the top cover 2, a fixing frame 4 disposed on the top of the fixing sleeve 3, and a sealing mechanism 5 disposed above the fixing sleeve 3 and fixedly connected to the top of the fixing frame 4.
Wherein, the outside of fixed cover 3 is provided with spacing boss, utilizes spacing boss to be convenient for fix fixed cover 3 when can carrying on spacingly fixed cover 3.
Wherein, the profile of mount 4 sets up to the U type, makes sealed lid 53 directly take out in can following the clearance between fixed cover 3 and the mount 4 through setting up the mount 4 to the U type, conveniently installs and dismantles sealed lid 53.
Wherein, sealing mechanism 5 cup joints the stop collar 51 inside mount 4 including fixed, dead lever 52 has been cup jointed in the inside activity of stop collar 51, dead lever 52 extends the outside bottom screw of stop collar 51 and cup joints the sealed lid 53 that carries out the contact between the top of lateral surface and fixed cover 3, and the outside cover of dead lever 52 bottom is equipped with the spring 54 that is located sealed lid 53 top, utilize spring 54 can cushion sealed lid 53, when preventing the cubical switchboard pressure release, produce the collision between sealed lid 53 and the mount 4, cause sealed lid 53 to damage.
Wherein, the outside profile of sealed lid 53 sets up to the spherical surface, utilizes spherical surface to make sealed lid 53 can and fixed cover 3 between seal, and when the cubical switchboard pressure release, high temperature high pressure air current can carry out even blowout through spherical surface simultaneously.
