The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as qualification of the present utility model.
The desk that has lowering or hoisting gear of the present utility model as shown in Figure 1 comprises desk, also comprises lowering or hoisting gear, and lowering or hoisting gear is to be bolted to the desk side.
As Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, lowering or hoisting gear comprises chute 1, slide block 2, position fixing knob 3; Slide block 2 is installed in the chute 1, and slide block 2 is provided with a deep hole 21 towards the one side of chute 1 opening, is provided with an elastomeric element 22 in the deep hole 21, and deep hole 21 bottoms are provided with pivoting device 23, and pivoting device 23 is connected with hook circle 24; Position fixing knob 3 comprises handle 31 and the positioning tooth 32 that protrudes to the both sides level, position fixing knob 3 one ends stretch in the deep hole 21 of slide block 2 and are connected with elastomeric element 22, a distance, end distance end outer rim that position fixing knob 3 stretches into described slide block 2 has annular projection 33 to block elastomeric element 22 in the deep hole 21, the deep hole 21 interior ends that described position fixing knob 3 stretches into slide block 2 are provided with the through hole 39 that is parallel to the slide block glide direction, near on the slide block 2 one side opening walls projection 34 is arranged in the described through hole 39, on projection 34 projecting surfaces on the hole wall fluted 35, projection 34 both sides fluted 36 on the hole wall, on the hole wall relative a spur 37 is arranged in the through hole 39 with the projection 34 place hole walls on the hole wall, spur 37 is relative with projection 34 protrusion directions on the hole wall, there is arc groove 38 spur 37 both sides, and hook circle 24 passes and tangle through hole 39; Chute 1 opening both sides are provided with location tooth bar 11, and location tooth bar 11 fixes with the positioning tooth 32 of position fixing knob 3 both sides and is connected, and chute 1 both sides are provided with bolting seat 12.
Holding handle 31 when needing the locking lowering or hoisting gear promotes position fixing knob 3 to slide block 2 directions, along with position fixing knob 3 stretches into deep hole 21 gradually, the arc groove 38 guiding hook circles 24 of spur 37 1 sides rotate to spur 37 directions, unclamp position fixing knob 3 this moment, position fixing knob 3 is in motion outside 21 outside deep hole under the effect of elastomeric element 22, make hook circle 24 tangle the groove 35 on the projection 34 on through hole 39 hole walls on the position fixing knob 3, the positioning tooth 32 of position fixing knob 3 both sides is main with the location tooth bar of chute 1 opening both sides 11 cards, position fixing knob 3 can not move up and down, the effect sliding block 2 that stretches into deep hole 21 parts on the slide block 2 at position fixing knob 3 can not move up and down, because the part that the effect of annular projection 33 makes position fixing knob 3 stretch into deep hole 21 on elastomeric element 22 in the deep hole 21 and the position fixing knob 3 is extrapolated to deep hole 21 by elastomeric element 22 again when being tangled by hook circle 24, hook circle 24 can't be deviate from the groove 35 on the projection 34 on 39 hole walls of the through hole on the position fixing knob 3, makes that whole lowering or hoisting gear is locked.Holding handle 31 during the locking that need unclamp lowering or hoisting gear promotes position fixing knob 3 to slide block 2 directions, make be positioned annular projection 33 compressions on the handle 3 of elastomeric elements 22 in the deep hole 21, thereby deviate from the groove 35 on the projection 34 on through hole 39 hole walls of hook circle 24 from the position fixing knob 3, and then run into the spur 37 relative with the projection 34 on through hole 39 hole walls, hook circle 24 is rotated to a side enter the arc groove 38 of spur 37 1 sides, position fixing knob 3 stretches into the part quilt of deep hole 21 to deep hole 21 extrapolations under the effect of elastomeric element 22, owing to lost the pulling force of hook circle 24, the part that position fixing knob 3 stretches into deep hole 21 begins outside motion, in this process, arc groove 38 guiding hook circles 24 fall on through hole 39 hole walls the groove 36 of projection 34 both sides, the outside movable stroke of position fixing knob 3 this moment is elongated, make the positioning tooth 32 of position fixing knob 3 both sides from the location tooth bar 11 of chute 1 opening both sides, to deviate from, so position fixing knob 3 can drive slide block 2 and slide up and down, the lowering or hoisting gear location is released.
As shown in Figure 6, lowering or hoisting gear also comprises rack 4, rack 4 comprises first support 41, second support 42, crossbeam 43 and shelf 44, first support 41, second support 42 is by being bolted to shelf 44 bottoms, crossbeam 43 two ends are vertically connected at first support 41 and second support, 42 middle parts, aforementioned slide block 2 end face both sides are provided with the through hole 26 of pair of parallel in slide block 2 glide directions, first support 41, second support 42 is inserted through the through hole 26 on the slide block 2, because stopping of crossbeam 43, rack 4 is held by slide block 2, makes the rack 4 can sliding up and down and oscilaltion along with slide block 2.
Lowering or hoisting gear can be installed in any side of desk, also can install simultaneously in the desk left and right sides, can also have the position of installing space to install arbitrarily at desk, thereby obtain farthest can adjust desktop and material-putting space.
The desk that has lowering or hoisting gear can use the fire proofing material manufacturing, as PLASTIC LAMINATED, can reduce disaster hidden-trouble like this.
The above only is the utility model preferred embodiment; be not so limit claim of the present utility model; so the equivalent structure that all utilization the utility model specifications and diagramatic content have been done changes, and all is included in the protection domain of the present utility model.
