In this folding platform, set up portable portion into movable structure, portable portion slides in the slide rail when the platform is opened, and the horizontal pole of portable portion can regard as the support of hanging the knot to test tube or other articles for use, also can realize the adjustment of position through the slip horizontal pole.
The two support arms for supporting the cross rod are hinged with each other, and mainly have two purposes, one is that when the hand-held part slides on the upper part of the platform, the support form of the two support arms is more stable, and the arrangement of the limiting block and the spring ensures that the bottoms of the support arms are in an isosceles triangle structure, so that the stability is stronger; in addition, the structure of the two support arms can facilitate the hand-held part to be contracted to the end part of the platform, the pulley on one support arm slides into the longitudinal slide rail at the end part of the slide rail firstly, at the moment, the pulley sliding into the longitudinal slide rail is not intersected with the transverse slide rail, the support arm at the other side is pressed to enable the pulley corresponding to the support arm to also enter the longitudinal slide rail, and then the two pulleys are supported at the two ends of the longitudinal slide rail under the action of the springs between the corresponding support arms to complete the conversion from the upper part of the platform to the side surface of the platform. The support arms with the bending parts are arranged on the opposite inner sides, and the purpose is that after the portable parts slide into the side faces of the platform, when the portable operation is carried out, the two support arms with the bending parts are also in an opposite state, so that the cross rods of the two portable parts can be close to each other, and an operator can conveniently carry the portable operation.
The slide on the curb plate is established to the U type, and its main effect is convenient for open the curb plate, and folding and when opening completely in addition, the hinge all corresponds the both sides top of slide, can guarantee folding and the compactness of open the state completely, can reduce the volume to fold condition, and open the state multiplicable stability.
The lock catch is designed to be tensioned through the tension spring to prevent looseness in use, meanwhile, the tension spring is not used as a component which plays a main role in locking, the lock catch is only used for preventing the lock hole from being separated, and the lock catch is used as a lock catch of a main locking component, and the locking objects of the lock catch are a side plate, a platform and a hinge shaft. Under fold condition, the latch of hasp passes curb plate, the rail board of platform and the draw-in groove on the hinge, makes the three form in step, and at this moment, the curb plate can not rotate around the hinge under the spacing of latch and draw-in groove, and hinge and rail board then form in step, and the hinge can not take place to rock in the platform is inside. Under the complete open mode, draw-in groove on the hinge and the draw-in groove on the rail board dock mutually, also dock with the draw-in groove on the curb plate simultaneously, and the draw-in groove of hasp also runs through the three simultaneously and carries on spacingly. The releasing and locking operation of the lock catch is to pull the lock catch outwards to separate the lock catch from the three parts.
What draw-in groove and buckle adopted is cross's design, therefore, can form arbitrary perpendicular or horizontal angle between the three, just so can reach a benefit, lie in when using this device as clean platform, curb plate and supporting leg department both are located a vertical plane and are the vertical form with the platform, when this platform need not use as clean platform, platform side below can be arranged in to the curb plate, also can prop up the platform and flush as storage platform and use, the area of platform has been enlarged to a certain extent. Simultaneously, we have set up two sets of through-holes corresponding with the supporting leg on the curb plate, on the backplate of curb plate was located to a set of through-hole, another group was located on the newly-increased baffle in curb plate bottom, no matter the curb plate is opened with level or vertical state like this, the supporting leg can pass the through-hole, also be equivalent to carry out spacing basis at original hasp to the supporting leg, it is spacing further to the supporting leg to have add the curb plate to the stability of further increase supporting leg.
New wind box integrates fan and filter screen, can supply air to the platform by the level when turning up and standing, roof and backup pad that set up on new wind box, on the one hand can cover the open end of new wind box when folding, play certain guard action, on the other hand is as the roof of clean work platform when opening, because of there is not the barrier on the curb plate upper portion after opening, we have still set up the backup pad at the roof lateral part, on the one hand seals the curb plate top, on the other hand also plays the effect of support, prevent the free end whereabouts of roof.
The whole folding and opening of the working platform are convenient, and a convenient operation platform is provided for the field sampling detection of food.
