Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It is noted that relative terms such as "first," "second," and the like may be used to describe various components, but these terms are not intended to limit the components. These terms are only used to distinguish one component from another component. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention. The term "and/or" refers to a combination of any one or more of the associated items and the descriptive items.

Referring to fig. 1, 2, 3 and 4, fig. 1 is a front view of a lower door interlock structure of a switch cabinet according to the present invention; fig. 2 is a side view of the lower door interlock structure of the switchgear of the present invention; FIG. 3 is a front view of the interlocking movable members; fig. 4 is a side view of the interlocking movable members. The utility model discloses a lower door interlocking structure of cubical switchboard, including interlocking movable part 4, layer board 9, coil spring 8, baffle 1 and ground connection operating axis 200 before the mechanism, ground connection operating axis 200 is provided with cam 2, interlocking movable part 4 includes the bar body 41 and the separation blade structure of being connected with bar body 41 one end, on bar body 41 was located to coil spring 8 cover, the bar body 41 other end passed layer board 9 back and was connected with the lower door of cable chamber 100, when rotating ground connection operating axis 200 through mechanism operating handle 300 in order to carry out the separating brake operation, cam 2 pushed down the separation blade structure and realizes the locking. Wherein, the lower door refers to a door body of the cable chamber. The utility model discloses a lower door interlocking structure of cubical switchboard for mechanism operating handle 300 rotates ground connection operating axis 200 when (figure 7, figure 8 are shown) in order to carry out the separating brake operation, cam 2 pushes down the separation blade structure and realizes the locking (figure 9, figure 10) based on the separation blade structure setting of cam, interlocking movable part, because of cam 2's existence, has a limiting displacement promptly, makes interlocking movable part 4 can not the rebound. The door panel can only be opened when the three-position switch is in the ground switch-on position, and the lower door of the cable chamber 100 can not be opened when the three-position switch is in the ground switch-off position, so as to avoid accidents.

When the grounding operating shaft is in the grounding closing position, the cam does not press the second plate-like structure in the catch structure, so that when the lower door is opened, the interlocking movable member can move upwards to open the cable chamber (not shown).

As shown in fig. 11, when the lower door is closed, the first plate-like structure 42 of the interlocking movable member moves downward with the pulling of the lower door, so that the external connection portion 201 of the ground operation shaft 200 is exposed with respect to the mechanism front bezel 1 and can be operated by the mechanism operation handle 300.

As shown in fig. 12, the switch cabinet grounding switch is in the grounding closing position, and when the lower door is not hung, the coil spring 8 is in the free state. The first plate-like structure 42 of the interlocking movable member 4 blocks the ground operating shaft 200 and cannot be operated by the operating mechanism handle.

As shown in fig. 3 and 4, the baffle structure includes a first plate-like structure 42 and a second plate-like structure 43 perpendicular to the first plate-like structure, and the second plate-like structure 43 is fixed to one end of the bar body 41. The first plate-shaped structure 42 is provided with a clamping groove 421 corresponding to the cam; when the mechanism operating handle 300 rotates the ground operating shaft 200 to perform the opening operation, the cam 2 presses the second plate-like structure 43 in the shutter structure to achieve locking, so as to prevent the interlocking movable member 4 from moving, i.e., to achieve locking of the lower door. Wherein, the supporting plate 9 is connected with the base of the switch cabinet.

As shown in fig. 5 and 6, preferably, the cable chamber further includes an interlocking fixing seat 5, the interlocking fixing seat includes a first seat 51 and a second seat 52 fixed to the first seat, after the other end of the rod 41 passes through the first through hole of the first seat, the coil spring 8 is sleeved in from the other end of the rod, and after the other end of the rod passes through the second through hole of the second seat, the other end of the rod passes through the supporting plate to be connected to the lower door of the cable chamber. This preferred embodiment is through the setting of interlocking fixing base for 8 one ends of coil spring are contradicted to first pedestal, and the other end is contradicted to the second pedestal, realize one to interlocking part 4's reset effect. In particular, the fixation between the interlocking fixing seat 5 and the bar body 41 is also achieved by the screw 7.

Wherein the rod body is in a shaft body shape. Preferably, the ground operating shaft is located above the interlock moving member.

The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
