Common horizontal hydraulic jack in the market, mainly comprise rack unit, hydraulic unit, the crane arm parts, carriage member, press hand and connecting rod, described rack unit comprises left wallboard and the right wallboard that is set parallel to each other, pass through bolt between described left wallboard and the described right wallboard, consist of after the nut assembling and removably connect, described crane arm parts are sleeved on a left side, the centre of right wallboard, described carriage member is installed in the front end of crane arm parts, described connecting rod has a pair of, lay respectively at a left side, right wallboard side, an end pivoting of connecting rod are connected on the corresponding left wallboard or right wallboard, the other end pivotal joint of connecting rod is on the carriage of crane arm parts.When lifting, press hand by repeatedly pressing down, promote the crane arm parts by hydraulic unit and up kick up, final by the carriage member on the crane arm parts with the weight jacking.The problem that said structure exists is: be threaded owing to adopts between the left and right wallboard, cause easily looseningly under the external force when jack uses in unfairness, bulk strength is inadequate, and needs the parts that assemble more, and production efficiency is low, and labor cost is relatively high.
In view of above-mentioned prior art, be necessary the rack construction on the existing horizontal hydraulic jack is improved, technical scheme described below produces under such background.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, bulk strength is high, the few and frame Integral hydraulic Horizontal jack of the structural development that packaging efficiency is high, productive costs is low of assembling parts.
The purpose of this utility model reaches like this, a kind of frame Integral hydraulic Horizontal jack of structural development, comprise rack unit, the crane arm parts, hydraulic unit, carriage member and press hand, described rack unit comprises left wallboard and the right wallboard that is set parallel to each other, described carriage member is installed in the front end of crane arm part length direction, the described hand of pressing is installed on the hydraulic unit, be characterized in: between described left wallboard and the described right wallboard in the front portion of length direction, front wheel spindle is passed through respectively in middle part and end, rear end, pivot shaft and rear fixed plate structure are for captiveing joint, described crane arm parts are set on the pivot shaft and can rotate around pivot shaft, the front end of described hydraulic unit is installed on the described crane arm parts by gudgeon pin shaft, and the rear end of described hydraulic unit is installed in the end, rear end of described left wallboard and right wallboard length direction by rear axle and matches with described rear fixed plate.
In a specific embodiment of the present utility model, the cross sectional shape of described rear fixed plate is U-shaped, on the two sides that facing each other of U-shaped is set in parallel, offer respectively the axis hole that passes for for the two ends of described rear axle, the two ends of described rear axle after passing described axis hole respectively with left wallboard, rear wall plate on corresponding axis hole be connected and fixed.
The utility model is because after adopting said structure, the beneficial effect that has: rational in infrastructure, reliable in action not only, avoided loosening because of what caused by external force in the prior art, the bulk strength of jack is increased, and reduced the quantity of parts assembling, improved production efficiency, reduced productive costs, made the Applicable scope of horizontal hydraulic jack wider.
