A kind of Self-fastening pcb board tote cart
Technical field
The utility model relates to logistics transportation field, particularly a kind of Self-fastening pcb board tote cart.
Background technology
At present, the transhipment of electronic product in factory is all generally brought with Turnover Box or transport, in workshop, pcb board is deposited is generally be positioned in special rack or storage bin, and the transhipment of pcb board, the following two kinds of modes of many Bian: one is utilize the transport box be positioned on plate pusher, but the upper and lower plate pusher of transport box is inconvenient, wasting manpower and material resources, in transport process, fragile pcb board, causes and scraps; Two is utilize transhipment vehicle frame, but adopts fastened by screw mode between this transhipment vehicle frame and pillar stiffener, and its weak point is that adjustment is convenient not, fastening insecure, when load-carrying is larger, there will be the relative sliding between bracket and pillar stiffener, thus can hidden danger be produced.
In the tote cart of transport pcb board, tote cart must spray anti-static coatings or carry out other forms of electrostatic prevention process, and in existing anti-static coatings, conducting medium mostly is conductive black or graphite powder.Because the electrode potential of conductive black or graphite powder is higher than steel, when directly contacting with steel, form electrochemical corrosion, make iron and steel accelerated corrosion as anode; And due to its oil absorption high, when conduction needs height, addition is comparatively large, and paint film is more loose, and shielding, permeability resistance decline, and cause underfilm corrosion, rust-preventing characteristic is not good.And the coating made thus, anti-corrosive properties and electric conductivity can not be taken into account, and service life is short.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, a kind of Self-fastening pcb board tote cart is provided, tote cart of the present utility model is owing to being provided with slide plate and spring, spacing between positioning vertical column and slide plate can be regulated arbitrarily, and then the storage of the pcb board of applicable various sizes, reach from holding pcb board tightly, without the need to manually fastening, easy to loading and unloading.
The technical solution adopted in the utility model is as follows: a kind of Self-fastening pcb board tote cart, comprise bracing frame, support frame as described above is made up of two main beam transverses, two long beams and four positioning vertical columns, described main beam transverse, long beam and positioning vertical column are assembled into a cuboid framework, two B-pillars are vertically provided with in bracing frame, the upper end of described B-pillar is connected to the middle part of the long beam on support frame as described above top, and the lower end of described B-pillar is connected to the middle part of the long beam of support frame as described above bottom; The bottom of the outer side frame of bracing frame and top are provided with along the guide rail on long beam direction, described guide rail are provided with the fluting of level; Be provided with the slide plate one and slide plate two that can slide along long beam direction in support frame as described above, described slide plate one and slide plate two lay respectively at the both sides of B-pillar, are evenly distributed with several pressure springs between slide plate one and slide plate two.
Further, described positioning vertical column is evenly provided with the angle steel of multiple symmetry on the side in bracing frame, the side that described slide plate one is relative with the angle steel of positioning vertical column with slide plate two is also provided with angle steel, described angle steel is provided with guide groove, four bights of the bottom of support frame as described above are separately installed with adapter plate, and the bottom surface of described adapter plate is provided with universal rolling wheel.
Further, one end of described pressure spring is fixedly connected with described slide plate one, the other end is fixedly connected with described slide plate two, spacing between described slide plate one and homonymy positioning vertical column is less than the length and width size of pcb board, and the spacing between described slide plate two and homonymy positioning vertical column is also less than the length and width size of pcb board.
Due to the setting of said structure, owing to being provided with pressure spring, in pcb board is carried, only need manually spacing between positioning vertical column and slide plate to be become large, and pcb board is placed in guide groove, now pressure spring is in compressive state, when manual operation is removed, pressure spring hold-off pressure promotes slide plate slides, guide groove consequently on slide plate tightly embraces pcb board, pcb board is fastened on tote cart, make pcb board that landing and high vibration can not occur, have and well carry effect, and when needs unloading pcb board, only need manual compression pressure spring, thus easy to loading and unloading.
Further, described slide plate one or be provided with several extension springs between slide plate two and homonymy positioning vertical column, described extension spring is distributed on the long beam on bracing frame top and the long beam of bottom.
In further alternative scheme of the present utility model, can spring be arranged between positioning vertical column and slide plate, also can be reached the effect of fastening pcb board by the stretching action of spring, namely bring effect easy to loading and unloading.
Further, described universal rolling wheel is provided with brake equipment.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: tote cart of the present utility model is owing to being provided with slide plate and spring, spacing between positioning vertical column and slide plate can be regulated arbitrarily, and then the storage of the pcb board of applicable various sizes, reach from holding pcb board tightly, without the need to manually fastening, easy to loading and unloading.
