Disclosure of Invention

The utility model aims to solve the technical problem that a plurality of panels that locking device, the device can press from both sides tight work piece make things convenient for the workman to weld each panel.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a locking device, includes the tight piece of clamp of fixing base, connecting rod and "U" shape, the fixing base be equipped with the bayonet socket, the connecting rod be equipped with connecting hole and pole, pole and bayonet socket can dismantle and be connected, the tight piece right side of clamp be equipped with right round pin axle and handle, thereby right round pin axle pass the connecting hole and make the connecting rod rotate around right round pin axle, the fixing base still be equipped with set screw, fixation nut, adjusting screw and adjusting nut, thereby set screw can pass and treat welded work piece and use fixation nut to fix the work piece in the fixing base upper end, adjusting nut fix and set up on the fixing base, adjusting nut and adjusting screw threaded connection.

As a further improvement of the utility model, the fixing seat comprises a fixing plate and a clamping plate. The fixed plate is arranged below the workpiece, and the clamping plate is used for connecting the connecting rod.

As a further improvement of the utility model, the fixing plate is provided with 4 fixing holes for fixing the shape of the Chinese character 'Yao', and the fixing screw is arranged in the fixing hole. The fixing screw penetrates through the workpiece and the fixing plate from top to bottom in sequence and is locked by the fixing nut.

As the utility model discloses further improve, adjusting nut's axis perpendicular with the axis of fixed orifices, adjusting nut's axis perpendicular with the axis of bayonet socket. The working principle of the utility model is that: the fixed plate passes through set screw, fixation nut fixed mounting is in treating the work piece bottom surface of welding (set screw and fixation nut need not fasten, only need take slightly tightly), then in the bayonet socket of fixing base is gone into to the pole card of connecting rod, pull the handle upwards after, the connecting rod right side also upwards moves simultaneously, it progressively diminishes to press from both sides the distance between tight piece left end and the bayonet socket, it moves to the right-hand member to then press from both sides tight piece left end drive work piece, thereby it exerts the thrust that moves left to begin to screw up adjusting screw to the work piece this moment, at last fasten set screw and fixation nut, then panel on the work piece is pressed from both sides tightly. The central axis of the adjusting nut is perpendicular to the central axis of the fixing hole, the central axis of the adjusting nut is perpendicular to the central axis of the bayonet, and therefore the purpose of the adjusting nut is that leftward moving thrust can be applied to a workpiece when the adjusting screw is screwed down, and then the adjusting screw and the clamping block lock the workpiece together.

As a further improvement, the clamping plate is provided with a slope. The slope face first effect can increase the joint strength of cardboard and fixed plate, and the second effect is that the slope face can restrict the range of pulling the handle upwards.

As a further improvement, the bayonet is arranged at the lower end of the slope. The connecting rod can rotate around the bayonet as a circle center, and limits the upward pulling amplitude of the handle.

As a further improvement, the left side of the clamping block is provided with a left pin shaft. The left pin shaft can penetrate into a plate on the left side of the workpiece.

As a further improvement of the utility model, the handle has an inclination angle. The inclination angle of the handle is convenient for a worker to pull, and the operation habit of the worker is met.

As a further improvement, the right side of the clamping block is provided with a gasket. The right pin shaft can rotate in the connecting hole of the connecting rod, the clamping block is not very thick, the gasket increases the thickness of the right side of the clamping block, and the clamping block is not easy to bend and deform when the right pin shaft rotates.

As a further improvement of the utility model, the handle is fixedly arranged at the gasket. When the handle is pulled, the clamping block is not easy to bend and deform.

The utility model has the advantages of simple structure, convenient operation and high efficiency; the fixing base passes through set screw, fixation nut fixed mounting is in treating the work piece bottom surface of welding (set screw and fixation nut need not fasten, only need take slightly tightly), then go into the bayonet socket of fixing base with the pole card of connecting rod, after upwards pulling the handle, the connecting rod right side also upwards moves simultaneously, press from both sides the distance between tight piece left end and the bayonet socket and diminish gradually, it removes to the right-hand member to then press from both sides tight piece left end drive work piece, thereby begin to screw up adjusting screw and exert the thrust that removes left to the work piece this moment, at last fasten set screw and fixation nut, then panel on the work piece is pressed from both sides tightly.
