Abstract
The utility model discloses a hasp device of an anti-explosion electrical box cover. The hasp device is used for tightening an upper cover and a lower cover of an anti-explosion electrical box body and comprises a buckling plate, a rotary fixing mechanism arranged at one end of the buckling plate and used for connecting the buckling plate with the upper cover and capable of enabling the buckling plate to rotate relative to the upper cover, and a fastening mechanism arranged at the other end of the buckling plate and used for fixing the buckling plate and the lower cover. When the buckling plate of the hasp device of the anti-explosion electrical box cover, disclosed by the utility model, is locked, the buckling plate is rotated to a position close to the lower cover and is fixed on the lower cover through the fastening mechanism; and when the buckling plate is opened, the fastening mechanism is opened, the buckling plate is rotated towards a direction departing from the lower cover, and then the upper cover can be separated from the lower cover. The hasp device of the anti-explosion electrical box cover, disclosed by the utility model, is simple in structure, larger in locking force and firmer and more durable in locking, and is capable of reaching the requirements of preventing water and explosion.
Description
Technical field
The utility model relates to a kind of clasp, particularly relates to a kind of clasp of explosion-proof electrification case lid.
Background technology
Powerful reliable secure engagement even sealing must be adopted in the mating face that each part of explosion-proof electrification casing cooperates, and, casing is not only wanted to bear extraneous brute force and is impacted, and also want to bear destructive tests such as internal gas blast, and the mating face between the experiment rear box can not be out of shape.So when designing this series products, it is enough big that coupling mechanism force is wanted, and cooperates enough firm fastening.
The locking mode of the explosion-proof electrification case lid of prior art adopts clasp to connect more, namely adopts the dead point principle locking of connecting rod slide mechanism, and connecting rod slide mechanism one end is fixed on and covers, the other end is fixed on down and covers, the rotation connecting rod drives lower cover and is close to loam cake, and is convenient to operation.But the coupling mechanism force of the clasp of the explosion-proof electrification case lid of prior art is big inadequately, locks firm fasteningly inadequately, is difficult to reach the waterproof anti-explosion requirement.
The utility model content
The purpose of this utility model be to avoid weak point of the prior art and provide a kind of simple in structure, locking force is big, the clasp of firm fastening explosion-proof electrification case lid.
The purpose of this utility model realizes by following technical measures:
A kind of clasp of explosion-proof electrification case lid, be used for loam cake and the lower cover of fastening explosion-proof electrification casing, comprise: buckle, be arranged at an end of described buckle the rotation fixed mechanism for the relative described loam cake rotation of described buckle that is used for connecting described buckle and described loam cake, be arranged at the retention mechanism that is used for fixing described buckle and described lower cover of the other end of described buckle.
Preferably, above-mentioned rotation fixed mechanism comprises: have the ball pressure head of first screw through-hole, the first protruding arm that is arranged at described buckle one end, first screw, be arranged at the rotation that cooperates with described ball pressure head of the described first protruding arm shrinkage pool, be arranged at first screw hole of described loam cake, described first screw screws in described first screw through-hole and described first screw hole successively.
Preferably, above-mentioned retention mechanism comprises: be arranged at the described buckle other end the second protruding arm, second screw, be arranged at the described second protruding arm second screw through-hole, be arranged at second screw hole of described lower cover, described second screw screws in described second screw through-hole and second screw hole successively.
The utility model compared with prior art has the following advantages: because the buckle of the clasp of explosion-proof electrification case lid of the present utility model can be by the relative loam cake rotation of rotation fixed mechanism; During locking: buckle rotation to the position that is adjacent to lower cover, is fixed on down buckle by retention mechanism and covers; When opening: open retention mechanism, towards the direction rotation buckle away from lower cover, this moment, loam cake and lower cover were separable.The clasp of explosion-proof electrification case lid of the present utility model simple in structure, and adopt this structure, locking force is bigger, locks more firm fasteningly, can reach the requirement of waterproof anti-explosion.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of the clasp of explosion-proof electrification case lid of the present utility model.
The specific embodiment
With accompanying drawing the utility model is further described with the following Examples:
A kind of clasp of explosion-proof electrification case lid, as shown in Figure 1, be used for loam cake 10 and the lower cover 20 of fastening explosion-proof electrification casing, comprise: buckle 30, be arranged at an end of described buckle 30 the rotation fixed mechanism 40 for described buckle 30 relative described loam cakes 10 rotations that is used for connecting described buckle 30 and described loam cake 10, be arranged at the retention mechanism 50 that is used for fixing described buckle 30 and described lower cover 20 of the other end of described buckle 30.Concrete, retention mechanism 50 can arrange corresponding number as required.
Because the buckle 30 of the clasp of explosion-proof electrification case lid of the present utility model can be by 40 relative loam cake 10 rotations of rotation fixed mechanism; During locking: buckle 30 rotations to the position that is adjacent to lower cover 20, are fixed on buckle 30 on the lower cover 20 by retention mechanism 50; When opening: open retention mechanism 50, towards the direction rotation buckle 30 away from lower cover 20, this moment, loam cake 10 was separable with lower cover 20.But loam cake 10 and the lower cover 20 of the clasp fastening explosion-proof electrification casing of explosion-proof electrification case lid of the present utility model, it is simple in structure, and adopts this structure, and locking force is bigger, locks more firm fasteningly, can reach the requirement of waterproof anti-explosion.
Preferably, as shown in Figure 1, rotation fixed mechanism 40 comprises: have the ball pressure head 42 of first screw through-hole 41, the first protruding arm 43 that is arranged at described buckle 30 1 ends, first screw 44, be arranged at the rotation that cooperates with described ball pressure head 42 of the described first protruding arm 43 shrinkage pool 45, be arranged at first screw hole 46 of described loam cake 10, described first screw 44 screws in described first screw through-hole 41 and described first screw hole 46 successively.After ball pressure head 42 is inserted in shrinkage pool 45, be fixed on the loam cake 10 by first screw 44, shrinkage pool 45 cooperates with ball pressure head 42, and buckle 30 can be the axis of rotation rotation with ball pressure head 42.
Preferably, as shown in Figure 1, retention mechanism 50 comprises: be arranged at described buckle 30 other ends the second protruding arm 51, second screw 52, be arranged at the described second protruding arm 51 second screw through-hole 53, be arranged at second screw hole (among the figure indicate) of described lower cover 20, described second screw 52 screws in described second screw through-hole 53 and second screw hole (indicating among the figure) successively.When with buckle 30 rotation when being adjacent to the position of lower cover 20, the second protruding arm 51 is adjacent to lower cover 20, by second screw 52 the second protruding arm 51 is fixed on the lower cover 20, and then with loam cake 10 and lower cover 20 fastenings of explosion-proof electrification case lid.
