Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Example 1:

a from locking electricity cabinet as shown in the figure, specific power cabinet that says so, this cabinet body includes the cabinet body, cabinet door 1, power switch 2 and mechanical switch 15, and power switch 2 is a safety or the master switch of whole distribution system, sets up in the outside of cabinet door, and mechanical switch 15 is ordinary lock, is used for shutting the cabinet door. Therefore, the cabinet door 1 is connected to the cabinet body in a switching manner, the power switch 2 is connected to the cabinet door 1 in a switching manner, and the mechanical switch 15 is connected to the side face of the cabinet door 1 in a switching manner. In the device, the principle of realizing self-locking is that when the power switch 2 is started, the mechanical switch 15 is closed in a linkage manner by staff. And the two do not interfere. Specifically, a set of crank slider mechanism is arranged on the inner cabinet door 1 at the power switch 2; a second slide way 10 is arranged on the inner side of the mechanical switch 15, a second slide block 11 is arranged in the second slide way 10 in a sliding connection mode, one end of the second slide block 11 is provided with a ratchet bar 12 in a switching mode, and ratchet teeth 14 are arranged on the ratchet bar 12; a ratchet structure is arranged on the rotating shaft of the mechanical switch 15 and connected with the ratchet bar 12, and a locking plate 17 is arranged on the rotating shaft of the mechanical switch 15; a transmission gear 7 is arranged between the second slide way 10 and the second slide block 11, and the transmission gear 7 is connected with the slide block of the slider-crank mechanism through a first rack 8 and is connected with the second slide block 11 through a second rack 9.

The device works in such a way that when the power switch 2 is rotated, a crank of the crank-slider mechanism rotates along with the rotation of the power switch, so that the slider is driven to slide, the sliding of the slider drives the first rack 8 to move, the first rack 8 moves to drive the transmission gear 7 to rotate, the transmission gear 7 rotates to drive the second rack 9 to slide, the second rack 9 slides to drive the ratchet bar 12 to move, the movement of the ratchet bar 12 drives the ratchet structure to rotate, and the ratchet structure is arranged on a rotating shaft of the mechanical switch 15 to drive the mechanical switch 15 to rotate and drive the locking plate 17 to lock the cabinet door.

Example 2:

on the basis of the above embodiment, in the present embodiment, in order to facilitate the rotation of the driving transmission gear 7, the crank block mechanism of the present device includes a crank 3, a first slideway 4, a first connecting rod 5, and a first block 6. Specifically, the crank 3 is fixedly arranged at the bottom of a rotating shaft of the power switch 2 and is close to the cabinet door 1, the first slide 4 is arranged on one side of the power switch 2 and is perpendicular to the cabinet edge of the cabinet door 1, and the first connecting rod 5 is rotatably connected with the first slide 4 and the crank 3.

Example 3:

on the basis of the above embodiments, in the present embodiment, in the present device, both the locking and unlocking of the power switch 2 and the mechanical switch 15 only need to rotate 90 degrees, and since most of the conventional power switches 2 are designed at the upper right of the mechanical switch 15, a set of crank-slider mechanism cannot be directly adopted to drive the ratchet bar 12, because there is only one outermost point of rotation and there is one innermost point, so that the longest point cannot drive the rotation angle of the mechanical switch 15 to rotate 90 degrees, and therefore, a certain steering is needed to be performed to make it rotate 90 degrees completely, and the first slideway 4 is arranged perpendicular to the second slideway 10.

Example 4:

on the basis of the above embodiments, in this embodiment, in order to facilitate the movement of the ratchet mechanism, the ratchet teeth 14 and the teeth of the ratchet wheel 16 of the ratchet mechanism are configured to be in the shape of teeth matched with each other, and the rear end of the ratchet teeth is configured to be in the shape of a circular arc as shown in the figure, so as to facilitate the retraction.

Example 5:

on the basis of the above embodiment, in this embodiment, in order to make the single movement of the mechanical switch 15 not interfere with the connection between the ratchet 16 and the ratchet bar 12, the device is provided with a flywheel between the ratchet 16 and the rotating shaft of the mechanical switch 15, and the locking plate 17 is fixedly arranged on the end surface of the flywheel. Therefore, in the actual movement process, the ratchet wheel bar 12 can only drive the ratchet wheel 16 to move forwards without influencing the retraction of the ratchet wheel bar 12, the ratchet wheel 16 drives the flywheel to rotate forwards without influencing the rotation of the middle rotating shaft of the flywheel, and thus, when the power switch 2 and the mechanical switch 15 are independently opened, the power switch 2 can drive the mechanical switch 15 to be closed to realize automatic locking only in the closing process.

Example 6:

on the basis of the above-mentioned embodiment, in the present embodiment, for the sake of normative operation and safety, the direction of the locking piece 17 of the present device coincides with the direction of the locking piece 17.

Example 7:

in addition to the above embodiments, in the present embodiment, in order to make the ratchet bar 12 closely contact with the ratchet 16, a spring is provided on the ratchet bar 12 to connect with the cabinet door 1.
