Embodiment

See also Fig. 1 and Fig. 2, the better embodiment of carriage of the present invention can be slidably connected to an electronic equipment one rack of accommodating this electronic equipment, this carriage comprise the cabinet 10 that is mounted on this electronic equipment sidewall pulley element and be mounted on accordingly the slide rail 20 of this rack.In present embodiment, this electronic equipment is server.

This pulley element comprise the mounting panel 11, of the sidewall that is mounted on cabinet 10 be vertically set on this mounting panel 11 front end fixed head 114 and be hubbed at two gears 113 of this mounting panel 11.This mounting panel 11 adjacent bottom places keep at a certain distance away and offer the two circular holding parts 111 that connect the bottom, and a gear 113 is pivoted in each holding part 111.Gear 113 exposes to the surface of mounting panel 11.The inboard of fixed head 114 is provided with a location mechanism 115 towards gear 113.The end of fixed head 114 forms two stators 116, and each stator 116 is offered a fixing hole 1161.The draw-in groove 118 of a level is offered in the rear end of mounting panel 11.

The bottom of the inboard of slide rail 20 side of cabinet 10 (namely towards) is installed with a tooth bar 21 along the length direction of slide rail 20.The top of the inboard of slide rail 20 is convexly equipped with some elasticity convex closures 23.The front end in the outside of slide rail 20 vertically is convexly equipped with two lugs 24, and each lug 24 is offered a fixing hole 241.The inboard of slide rail 20 sets firmly a positioning block 25 in the rear end of tooth bar 21.

See also Fig. 3, detent mechanism 115 comprises that the stop bit spare 1154 and that accommodating member 1153, that an axostylus axostyle 1151, that is fixedly arranged on fixed head 114 is sheathed on axostylus axostyle 1151 is sheathed on axostylus axostyle 1151 and is contained in accommodating member 1153 is sheathed on axostylus axostyle 1151 and is contained in the elastic component 1155 of supporting stop bit spare 1154 in accommodating member 1153.Accommodating member 1153 comprises a host cavity 11531, and the first end of stop bit spare 1154 is provided with a wedge-shaped part 11541 and stretches out outside host cavity 11531, and wedge-shaped part 11541 comprises an inclined-plane 11543.The second end of stop bit spare 1154 is contained in host cavity 11531 with being provided with stage portion 11542 splines and blocks shelves in host cavity 11531 inboards.Elastic component 1155 is contained in host cavity 11531 and between stage portion 11542 and host cavity 11531 inwalls.Accommodating member 1153 is offered two towards a side of fixed head 114 and is 180 location holes 11533 of spending the angle.Also fix an alignment pin 1152 parallel with axostylus axostyle 1151 on fixed head 114, this alignment pin 1152 snaps in selectively wherein that a location hole 11533 is interior to be positioned and spline accommodating member 1153.

In the time of cabinet 10 need to being slipped into rack, make the inclined-plane 11543 of stop bit spare 1154 down, promotion cabinet 10 makes gear 113 nibble to be incorporated on tooth bar 21 with the tooth bar 21 of slide rail 20 and rotates counterclockwise, the inclined-plane 11543 that the gear teeth of the gear 113 of positioned adjacent mechanism 115 push stop bit spare 1154 retreats stop bit spare 1154 compression elastic pieces 1155, cross wedge-shaped part 11541 to these gear teeth, the rest may be inferred, the gear teeth of gear 113 can be crossed successively wedge-shaped part 11541 and make cabinet 10 slip into rack, until locating piece 25 snaps in draw-in groove 118.In the process that slips into, after the gear teeth of gear 113 are crossed wedge-shaped part 11541, can not reverse under the effect of wedge-shaped part 11541, and then gear 113 is formed inverted orientation, to avoid in the situation that operating personnel neglect, cabinet 10 skids off in rack.Elasticity convex closure 23 elasticity of slide rail 20 are resisted against the mounting panel 11 of cabinet 10.

In the time of cabinet 10 need to being skidded off in rack, slightly outwards extract this accommodating member 1153, make alignment pin 1152 from wherein deviating from a location hole 11533, after axostylus axostyle 1151 is with accommodating member 1153 Rotate 180 degree, alignment pin 1152 is snapped in an other location hole 11533, and at this moment, stop bit spare 1154 also can be with accommodating member 1153 Rotate 180 degree, and then the inclined-plane 11543 that makes stop bit spare 1154 up, cabinet 10 can be skidded off along tooth bar 21.

For the sake of assurance, after cabinet 10 slips into rack fully, can utilize a screw (not shown) to pass fixing hole 1161 and lock fixing hole 241 and be fixed.

The gear 113 of carriage of the present invention makes the cabinet 10 of server can skid off reposefully or slip into rack with tooth bar 21 engagements, and detent mechanism 115 rotates gear 113 on demand along predetermined direction, and is safe and reliable when server is used.
