Abstract
The utility model relates to a novel switch cabinet pressure-releasing device. A pressure-releasing board in the prior art can be ejected with high speed and turns along a connecting position, as a result, a worker can be accidentally hurt easily, while, with the novel switch cabinet pressure-releasing device of the utility model adopted, the potential safety hazards in the prior art can be eliminated. The novel switch cabinet pressure-releasing device is characterized in that an L-shaped baffle is fixed on a switch cabinet body; a pressure-releasing board has a first position which contacts with the L-shaped baffle and a second position which is separated from the L-shaped baffle; the switch cabinet body is provided with a first fixing hole; the pressure-releasing board is provided with a second fixing hole of which the diameter is identical with that of the first fixing hole; and the first fixing hole and the second fixing hole are matched with nylon screws. The novel switch cabinet pressure-releasing device of the utility model is provided with the L-shaped baffle, such that injury of people caused by the high-speed ejection of the pressure-releasing board can be avoided, and the safety performance of the mechanism can be improved.
Description
Technical field
The utility model relates to a kind of pressure relief device, is specifically related to a kind of novel switched cabinet pressure relief device.
Background technology
Switch cubicle is a kind of switchgear assembly and control appliance, and the cabinet top of switch cubicle is provided with pressure relief device, and when being short-circuited accident in the switch cubicle, the gases at high pressure of generation will excrete out from the pressure relief device of switch cubicle; Existing pressure relief device is to be provided with metal cover board at the top of switch cubicle, one end of metal cover board has strip hole, fix with the steel screw, the other end of metal cover board has through hole, fix with nylon screw, when being short-circuited accident in the switch cubicle, nylon screw suffers the very fast thawing of high temperature, produces gases at high pressure in the switch cubicle and makes the metal cover board pressure release of upspringing.There is certain defective in this switch cubicle, nylon screw melt during this period of time in, the gases at high pressure that produce in the cabinet are further piled up, when nylon screw thoroughly melted, pressure relief plate was upspring at a high speed, along the hinge upset, accidentally injured the staff easily, had potential safety hazard.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of novel switched cabinet pressure relief device, has mainly solved existing pressure relief plate and has upspring at a high speed, along the junction upset, accidentally injures the staff easily, has the problem of potential safety hazard.
The technical scheme that the utility model adopts is: a kind of novel switched cabinet pressure relief device, comprise pressure relief plate, pressure relief opening, nylon screw, described pressure relief opening is positioned at switch cubicle body upper end, described pressure relief plate is connected with the switch cubicle body and is suitable with pressure relief opening, L type baffle plate is fixedly arranged on the described switch cubicle body, described pressure relief plate has the primary importance and the second place of separating with L type baffle plate with the contact of L type baffle plate, described switch cubicle body is provided with first fixing hole, described pressure relief plate is provided with second fixing hole isometrical with first fixing hole, described first fixing hole, second fixing hole and nylon screw are adaptive.
Described pressure relief plate is provided with groove, and described switch cubicle body is provided with the snap ring adaptive with groove.
The beneficial effects of the utility model are: be provided with L type baffle plate in mechanism, prevented the phenomenon that pressure relief plate is upspring at a high speed and hurted sb.'s feelings effectively, improved the security performance of mechanism.
Description of drawings

Fig. 2 is the structural representation of pressure relief plate 1.
1-pressure relief plate among the figure, 2-pressure relief opening, 3-nylon screw, 4-switch cubicle body, 5-L type baffle plate, 6-first fixing hole, 7-second fixing hole, 8-groove, 9-snap ring.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As Fig. 1 in conjunction with shown in Figure 2, a kind of novel switched cabinet pressure relief device, comprise pressure relief plate 1, pressure relief opening 2, nylon screw 3, described pressure relief opening 2 is positioned at switch cubicle body 4 upper ends, described pressure relief plate 1 is connected with switch cubicle body 4 and is suitable with pressure relief opening 2, L type baffle plate 5 is fixedly arranged on the described switch cubicle body 4, described pressure relief plate 1 has the primary importance and the second place of separating with L type baffle plate 5 with 5 contacts of L type baffle plate, described switch cubicle body 4 is provided with first fixing hole 6, described pressure relief plate 1 is provided with second fixing hole 7 isometrical with first fixing hole 6, described first fixing hole 6, second fixing hole 7 is adaptive with nylon screw 3.
Described pressure relief plate 1 is provided with groove 8, and described switch cubicle body 4 is provided with the snap ring 9 adaptive with groove 8.
The concrete use of the utility model is as follows: when mechanism was short-circuited accident, pressure, the temperature of gas raise fast, and nylon screw 3 melts, and under the effect of gases at high pressure, pressure relief plate 1 is upspring at a high speed, is blocked by L type baffle plate 5 behind the certain angle of upspringing.
The beneficial effect of utility model is: be provided with L type baffle plate in mechanism, prevented the phenomenon that pressure relief plate is upspring at a high speed and hurted sb.'s feelings effectively, improved the security performance of mechanism.
