Embodiment 1
A kind of integral type blackboard eraser chalk holder as shown in Fig. 1, Fig. 3, Fig. 4, integral type blackboard eraser chalk holder, including chalk holder 1, this chalk holder 1 back is provided with the drawer 21 for installing board wiper box 2; Chalk holder 1 is the box body having an opening above, and is stamped lid 11 above chalk holder 1; Chalk holder 1 be internally provided with multiple groove 12 for filling chalk, the axial cross section shape of groove 12 is identical with the axial cross section shape of chalk; Board wiper box 2 is arranged in drawer 21 for pullable. Passing through hinge 27 between lid 11 and chalk holder 1 hinged, lid 11 can be opened from chalk holder 1 upper shed upset or close. Lid 11 edge is provided with buckle 13, and the sidewall at chalk holder 1 is provided above the bayonet socket 14 coordinated with buckle 13, buckle 13 be buckled in bayonet socket 14 inner after, lid 11 and chalk holder 1 are fixed. Respectively arranging slide rail 22 in the sidewall of the opening both sides of drawer 21, this slide rail 22 is fitted with the slideway 23 phase interworking being located on board wiper box 2, so that board wiper box 2 can be steady during pull in drawer 21. The side wall ends of the opening both sides of drawer 21 is provided with barrier sheet 24, and this barrier sheet 24, for stopping the convex sheet 25 being arranged on board wiper box 2, further avoid the problem that senior general's board wiper box 2 of exerting oneself when pulling board wiper box 2 pulls out in drawer 21. Board wiper box 2 is positioned on the sidewall of drawer 21 opening direction and is also equipped with pull-out handle 26, it is simple to pull-out board wiper box 2.
As shown in Figure 2, locked groove 4 it is provided with in the front panel of board wiper box 2, locked groove 4 central button mechanism, the lateral symmetry of button mechanism is connected to two flexible ropes 35, after the cylinder 35 being fixedly installed in locked groove 4 walked around by each rope 35, one end is connected with button mechanism, and the other end is connected with locking bar 36;Locking bar 36, through the baffle plate 37 being arranged in locked groove 4, locking bar 36 is fixedly installed limiting plate 39, is set with lock rod spring 38 on locking bar 36, and lock rod spring 38 is between limiting plate 39 and baffle plate 37; Open keyhole 214 inside the side plate 211 of drawer 21, locking bar 36 is after the sidewall of board wiper box, and its end coordinates with lockhole 214; Button mechanism includes the button connecting plate 33 being connected with rope 35, the front of button connecting plate 33 connects button 3 by connecting rod 31, button 3 is arranged in the perforate in board wiper box front, is provided with spacing dividing plate 32 in the both sides of locked groove 4 inside connecting rod 31, and locking bar 36 end has hemispherical nose 40. Button spring 34 it is additionally provided with between button connecting plate 33 and locked groove 4, at least one compression spring 213 is set between squab panel and the squab panel of drawer 21 of board wiper box 2, side plate 211 vertical edge of drawer 21 has angle 41 with the position of locking bar 36 same level.
Board wiper box 2 is positioned at drawer 21 and is in the lock state, when needing pull-out board wiper box 2, button press 3, when button 3 moves in locked groove 4, the button connecting plate 33 being connected with button 3 pulls two ropes 35 to move, rope 35 pulls locking bar 36 to move in locked groove 4, the end making locking bar 36 departs from lockhole 214, owing to compression spring 213 is storage power state when lock-out state, now under the resilient force of compression spring 213, board wiper box 2 moves to drawer 21 inside and outside, thus can open board wiper box 2, and now lock rod spring 38 and button spring 34 are by compression storage power, board wiper box 2 is after the internal ejection of drawer 21, release button 3, button 3 resets under the reseting elasticity of button spring 34.
