Detailed description of the invention
As shown in Figure 2, support 4; Parallelly be fixed on left rail 2 on support 4 and right guide rail 3, the medial surface of this left rail 2 and right guide rail 3 is equipped with the gathering sill inserting for grid 1 or exit; The grid 1 that tail end has semicircle orifice is arranged between left rail 2 and right guide rail 3.
Shown in composition graphs 3, support 4 is U-shaped, and have a transverse slat and be connected to 2 side plates of transverse slat two end, being fixedly connected with a fixing head 41 in the outer side edges of transverse slat, is L-type between this fixing head 41 and transverse slat; Fixing head 41 is fixedly installed at least one fixed block 42, each fixed block 42 is fixedly connected with a sense switch 433; A side plate is fixedly connected with line slideway 46 wherein, line slideway 46 arranges a slide block 47; Latch 44 (concrete structure of latch 44 as shown in Figure 4) and baffle plate 45, the two is screwed the slide block 47 at line slideway 46, wherein baffle plate 45 has baffle body and is arranged on the limited block 451 of baffle body one side, is limited the motion of grid 1 by limited block 451; Extension spring 48 one end soket head cap screw 49 is fixed on the side plate of support 4, and the other end hangs on baffle plate 45.
The structural representation of the left rail 2 shown in composition graphs 5, left rail 2 comprises: installing plate 21; Be fixed at least one the spring bearer plate assembly 22 on installing plate 21, by spring bearer plate assembly 22 pairs of grids 1 to the right guide rail 3 direction produce pressure; Push rod 23 and the circular hole guide pad 24 that push rod 23 is play the guiding role and flat hole guide pad 25, and circular hole guide pad 24 and flat hole guide pad 25 are fixedly connected on installing plate 21 respectively; Be fixed on the locking spline 26 on installing plate 21, locking spline 26 is connected with spline guide pad 27 by Compress Spring 28; Be connected to the driver plate 29 between the end of push rod 23 and locking spline 26, driver plate 29 arranges the first through hole and the second through hole respectively, the first screw pole 30 is fixedly installed at the end of push rod 23, and the first screw pole 30 is arranged among the first through hole, and driver plate 29 is connected with locking spline 26 by the second through hole by the second screw pole 31; And driver plate 29 is connected with the driver plate rotating shaft 33 be fixed on installing plate 21.
Push rod 23 moves forward under the effect of thrust, by the first screw pole 30, driver plate 29 is rotated around driver plate rotating shaft 33, and then pulls locking spline 26 laterally under the second screw pole 31 acts on, and is compressed by locking spline 26 pairs of Compress Springs 28.
In addition, left rail 3 comprises installing plate and is arranged at least one the spring bearer plate assembly on installing plate 21.
Operation principle of the present invention is as follows:
In the process inserting grid 1, the tail end of grid 1 can promote baffle plate 45 on support 4 linearly guide rail 46 travel forward, make extension spring 48 produce elastic force simultaneously, when the inclined-plane of locking spline 26 touches the ball bearing on latch 44, according to wedge transmission principle, thrust when grid 1 inserts can produce the component along the spline direction of motion to locking spline 26, thus locking spline 26 is moved laterally, Compress Spring 28 simultaneously, until locking spline 26 sticks in the draw-in groove of latch 44 under the effect of Compress Spring 28 restoring force.Now, stop inserting grid 1, it keeps resting state under the pressure of spring bearer plate assembly 22.
In addition, the tail end of grid 1 has a breach, than being illustrated in figure 2 semicircular indentations.Therefore, the present invention distinguishes dissimilar grid by the shape detecting grid 1 tail end: when grid 1 tail end with sense switch 43 correspondence position is smooth limit, will produce signal by detection trigger switch 43 in the process inserting grid 1; When grid 1 tail end with sense switch 43 correspondence position has semicircular indentations, would not produce sense switch 43 and trigger, thus the grid of which kind of type can be judged as.
When ejecting grid 1, push rod 23 being exerted a force, locking spline 26 is moved laterally, when after disengagement latch 44, baffle plate 45 under the restoring force effect of extension spring 48 linearly guide rail 46 move, and then outwards eject grid 1.When after relieving push rod 23, under the effect of Compress Spring 28 restoring force, locking spline 26 and push rod 23 playback, and what finally realize grid 1 enters locking and ejection.
To sum up, the present invention is the anti-sliding stop of energy automatic locking grid in the process inserting grid, and can detect the model inserting grid, the manual operation push rod when ejecting grid, and whole process is without electronic auxiliary.When implementing of the present invention in flat panel detector box, in limited installing space, namely reduce cost, achieve again grid ejection function.In addition, the present invention has compact conformation, lower-cost advantage, and owing to being Purely mechanical structure, has advantage easy to maintenance, to be convenient to dismounting and replacing.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
