Embodiment Construction
[0015] Below in conjunction with accompanying drawing, technical scheme of the present invention is further described:
[0016] see figure 1 , 2 3. The cam interlocking device of the cabinet door includes a linkage lock plate 2 arranged on the inner wall of the switch cabinet body 1, and a plurality of relief holes for the operation shaft of the switch handle to pass through are provided on the linkage lock plate. It consists of two connected through slots 3 and 4 of different sizes. A cam 5 that drives the interlocking lock plate to reciprocate is set in the switch cabinet body. The cam is set on the switch cabinet body through the cam shaft 6 fixedly connected with it. The cam shaft extends An interlocking turning block 7 is fixedly installed outside the switch cabinet body, and an operation hole 8 is opened on the interlocking turning block. A shaft sleeve 9 is provided between the camshaft and the switch cabinet;
[0017] Wherein, the interlocking lock plate 2 is fixedl...

The invention relates to a cabinet door cam interlocking device. The cabinet door cam interlocking device comprises an interlocking plate, wherein the interlocking plate is arranged on an inner wall of a switch cabinet body; a plurality of avoidance holes are formed in the interlocking plate; a switch handle operation shaft penetrates through the avoidance holes; a cam is arranged in the switch cabinet body; the cam is arranged on the switch cabinet body through a cam shaft which is fixedly connected with the cam; a driving rack is arranged on the interlocking plate; a first gear, a first transmission rack and a second transmission rack are arranged on the switch cabinet body; the first gear is meshed with the driving rack; the first transmission rack and the second transmission rack are arranged on the switch cabinet body; the first transmission rack is connected with the second transmission rack through a connection rod; the first gear is in meshed transmission with the first transmission rack; a second gear and a locking block are arranged on the switch cabinet body; the second gear is meshed with the second transmission rack; and the locking block is coaxially fixed with the second gear and used for limiting a switch door body. The cabinet door cam interlocking device has no dead point position, is smooth, simple to manufacture and mount, and convenient to maintain; connection of the cabinet door cam interlocking device is rigid connection; and service life is greatly prolonged.
Description
technical field [0001] The invention relates to the technical field of a combined switch for mine blasting equipment, in particular to a cam interlocking device for a cabinet door. Background technique [0002] The door locks of the combination switch interlocking mechanism in the existing blasting equipment industry are mostly in the form of a four-bar mechanism, in the form of a cable, which is prone to dead spots, and the rigidity is insufficient, resulting in interlock failure, high manufacturing costs, and shortened service life. . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a cabinet door cam interlock device with reasonable structural design, sensitive operation, low manufacturing cost and long service life [0004] The technical scheme that solves the above-mentioned technical problem is as follows: [0005] The cam interlocking device of the cabinet door includes a linkage lock plate arranged on ...
