Abstract
The invention discloses a test-tube end cover self-opening device. The device comprises a turntable arranged on the base and an oscillating mechanism composed of a parallel rod, an oscillating rod, a supporting rod and a support, wherein the upper hollow-out section of the vertical support is hinged with the supporting rod; a positioning plate is fixedly connected on the top of the support; an elastic pressing mechanism is arranged on the right side of the waist of the support, a cam sharing the same shaft of an electric motor is arranged on the right side; the oscillating rod hinged with the base contacts with the right side of the cam; the upper part of the oscillating rod is hinged with the parallel rod, the parallel rod traverses through the hollow-out part of the support to be hinged with the supporting rod, and the left end of the parallel rod is fixedly connected with the tip of the plate. When the outline of the cam increases gradually, the elastic pressing mechanism moves left to press the outer wall of the test-tube of the end cover to be opened, the parallel rod moving rightward with the oscillating rod pulls the end cover out of the test-tube, and then a lift-up rod in the tip of the plate pushes the end cover out. When the cam rotates and the outline decreases gradually, the end cover returns the initial state. By using the device of the invention, the test-tube end cover arranged on the turntable can be automatically opened, thus the operator can not directly touches the test-tube and the test-tube can not be polluted.

The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Test-tube end cover self-opening device shown in the accompanying drawing 1, it comprises the rotating disk 1 that is installed in the left side, base 11 upper surface and the swinging gear on the right.Described rotating disk 1 is the circular frame of horizontal, and the uniform upright opening plug-in mounting of outer edge test tube 12, power operated rotating disk 1 go to test tube 12 and open end socket lid station.The swinging gear on the right is four linkage swing mechanisms, and it comprises the bearing 5 of flat bar 3, fork 8, pole 6 and stationkeeping.The built-in pole that is hinged 6 in bearing 5 epimere hollow out places of vertically-arranged, locating plate 5.1 is fixedly connected on the cantilever design of bearing 5 tops formation towards rotating disk 1, the cantilever end of locating plate 5.1 is the wedge shape, and the angle of its baseplane and last hypotenuse is 15 °～30 °, and present embodiment is 20 °.Bearing 5 waists are provided with the elastic compression mechanism 4 towards a left side, promote test tube 12 outer walls that elastic compression mechanism 4 moves to left and compresses rotating disk 1 plug-in mounting by cam 7, the cam 7 that install on bearing 5 waist right sides is coaxial with motor 9, cam 7 is between elastic compression mechanism 4 and fork 8, by drawing spring 10 tractives, the outline that keeps cam 7 contacts synchronously with the roller of elastic compression mechanism 4 right-hand members and the roller of fork 8 waists respectively between bearing 5 and the fork 8.Described flat bar 3 penetrates from bearing 5 epimere hollow outs, and the wrench 2 of its left end captive joint is positioned on the test tube 12, and right-hand member and fork 8 upper ends are hinged, and stage casing and pole 6 are hinged the formation leverage.Described fork 8 bottoms and base 11 are hinged, and the rotation direct drive fork 8 of cam 7 is made reciprocally swinging, and fork 8 affects flat bar 3 to make traverse motion.Described wrench 2 is actuating units of opening the end socket lid, and what it comprised that as shown in Figure 5 nail 2.1, outer leaf spring 2.2, interior leaf spring 2.4 and likeness in form be inverted L lifts up bar 2.3.Wrench 2 overall fixed are connected flat bar 3 left ends, laterally move back and forth with flat bar 3, as shown in Figure 1 for treating opening, cover opening for end socket as shown in Figure 3 during right lateral during left lateral.
The concrete operating condition of opening the end socket lid is: rotating disk 1 is installed the test tube 12 of waiting to open the end socket lid, is positioned at the station to be opened that is under the wrench 2.Motor 9 rotates double-linked cam 7, cam 7 drives elastic compression mechanism 4 and fork 8 respectively with outline, when cam 7 outlines increase gradually, elastic compression mechanism 4 is moved to the left and compresses test tube 12 outer walls of waiting to open the end socket lid, simultaneously, fork 8 is swung the flat bar 3 of linkage to the right and is moved to right, the wrench 2 that moves with flat bar 3 shown in the accompanying drawing 1, at first the nail 2.1 with horizontal thrusts in the end socket lid, then lifting up the be positioned wedge of plate 5.1 of bar 2.3 upper ends inserts, promote seesaw 2.3 and make lifting up of respective amount along wedge, lift up bar 2.3 on lift up and make the end socket lid of nail on 2.1 break away from test tube 12, the bar 2.3 of lifting up that continues to lift up is lifted up to nail 2.1 most advanced and sophisticated places, and the end socket lid breaks away from from following closely 2.1 as shown in Figure 5, and so far whole opening process finishes.When cam 7 outlines that rotate reduced gradually, under the effect of tension spring 10, the flat bar of putting with cam 7 left sides 3 of fork 8 drives moved to left to initial condition, contracts in the elastic compression mechanism 4 simultaneously, and rotating disk 1 rotates a station again.Operation is in proper order all dismantled the test-tube end cover of installing on the rotating disk 1 automatically.
