The invention relates to the technical field of armored optical cable installation equipment, and discloses an armored optical cable clamping device and an optical cable clamping method.The armored optical cable clamping device comprises a device shell used for installing internal components, a clamping mechanism and a power block arranged on the side wall of the device shell in a sliding mode, and a first clamping plate is fixed to the outer wall of the power block; first sliding rods are symmetrically fixed to the inner walls of the upper side and the lower side in the device shell, sliding blocks are slidably arranged on the first sliding rods, and sliding plates, second moving plates, mounting plates, mounting rods, mounting plates and second clamping plates are arranged on the side walls of the sliding blocks through first supporting rods. The device is reasonable in design, the clamping mechanism can be driven to clamp and fix an armored optical cable without extra power, meanwhile, clamping and fixing of armored cables of different sizes can be better met, the applicability of the device is improved to a certain degree, and in addition, due to the arrangement of the locking mechanism, the clamping mechanism is convenient to use. Therefore, the clamping and fixing quality of the device on the armored optical cable is ensured.

The utility model relates to the technical field of junction boxes, in particular to a buckle type junction box convenient to disassemble and assemble, which comprises a box body, a box cover and a locking assembly, the box body is rotatably connected with the box cover, two ends of the box body are respectively provided with a wire inlet and a wire outlet, the locking assembly consists of a fixed part and a movable part, and the fixed part arranged in parallel left and right is connected with the box body. And movable pieces arranged in parallel left and right are connected to the box cover. According to the utility model, when the box cover is in contact with the box body, the first L-shaped plate and the clamping block are in contact with the matching groove formed in the matching block, and the second L-shaped plate and the self-locking block are inserted into the limiting grooves formed in a large number of fixing pieces, so that the first L-shaped plate and the second L-shaped plate form a double-self-locking structure; the problem that a common self-locking structure is loosened and falls off due to external force and leg contact is avoided, meanwhile, the fixing piece is connected to the mounting plate, and the fixing piece is rapidly replaced by disassembling and assembling the mounting plate so as to reduce later maintenance and use cost.
