Description
Technical field
The utility model relates to the railroad technical field, refers in particular to a kind of railroad with auto-lock function.
Background technology
Slide rail is a kind of device that relatively moves that is used for realizing two adjacent articles, and as the keyboard drawer of routine office work with table, mostly the folding of keyboard drawer is to realize by railroad.The slide rail operated by rotary motion has outer rail and interior rail, and outer rail is connected on the object of two relative foldings of needs with interior rail, for the resistance of reducing friction, is provided with the ball carriage usually between outer rail and interior rail, makes both foldings convenient and smooth and easy many really.But such architectural feature has been brought some other drawbacks, because reducing of frictional force, interior external slide rail can be free to slide along track is two-way, when external force effect following time need be moved or be subjected to object, the object that is connected with slide rail (as keyboard drawer) can not effectively remain on collapse state, slide easily, the object that is connected with slide rail can play pendulum, even can skid off and break away from object and cause the accident of falling damage.
The utility model content
The utility model is the deficiency at present railroad existence, and provides a kind of slide rail to have the railroad of auto-lock function under collapse state.
For achieving the above object, the utility model adopts following technical scheme:
A kind of railroad with auto-lock function, it includes interior rail, outer rail, interior rail, outer rail all is the square frame shape that three faces surround an opening, interior rail, the outer rail opening fastens in opposite directions and nests together, be provided with the advance ball device between outer rail and interior rail, be provided with a projection in the inside groove of outer rail one end, the corresponding self-locking device that is provided with of interior rail one end, self-locking device include one be arranged in a fixed head in the inside groove of rail, fixed head is provided with a fluting, and sliding on the fluting is embedded with a buckle, and buckle protrudes in the outside and is provided with a projection button hole, also be provided with pipe position step in the described fluting, described buckle rear end downside is provided with corresponding pipe position breach; The buckle lower end is provided with an elastic component that is connected with the fixed head end.
Wherein said elastic component is a tension spring.
Wherein said buckle front end upside also is provided with anti-skidding mouthful.
Wherein said buckle front end upper and lower sides is provided with the angle position.
The beneficial effects of the utility model are: connection object of the present utility model is when drawing back state, the pipe position indentation, there of buckle rear end is at the step place, pipe position of fluting, elastic component is in state of tension, buckle is in lower position, when inwardly pushing away to fold the time, the projection of outer rail touches the projection button hole on the buckle and promotes buckle, make pipe position breach break away from pipe position step, under the elastic component effect, buckle is in step top, pipe position, projection just enters the projection button hole and is lived by projection button hole pipe clamp, and the connection object that is attached thereto like this is locked, can not be free to slide; When needs drew back, pulling connected object, makes it to overcome the elastic component pulling force, when the pipe position breach with buckle was pulled to step place, pipe position, buckle had been located lower position by the higher position, and projection just breaks away from the constraint of projection button hole, the connection object that is attached thereto unlocks, and can be free to slide; The utility model is simple in structure, and effectively locking connection object under collapse state makes it and can not be free to slide; And it is simple to unlock.

The specific embodiment
Be further elaborated below in conjunction with Fig. 1-5 pair the utility model:
A kind of railroad with auto-lock function, it includes interior rail 1, outer rail 2, interior rail 1, outer rail 2 all is the square frame shape that three faces surround an opening, interior rail 1, outer rail 2 openings fasten in opposite directions and nest together, 1 on outer rail 2 and interior rail are provided with advance ball device 3, be provided with a projection 21 in the inside groove of outer rail 2 one ends, the corresponding self-locking device 11 that is provided with of interior rail 1 one ends, self-locking device 11 include one be arranged in a fixed head 111 in the inside groove of rail 1, fixed head 111 is provided with a fluting 112, slide on the fluting 112 and be embedded with a buckle 113, buckle 113 protrudes in the outside and is provided with a projection button hole 114, also be provided with pipe position step 115 in the described fluting 112, described buckle 113 rear end downsides are provided with corresponding pipe position breach 116; Buckle 113 lower ends are provided with elastic components 117 that are connected with fixed head 111 ends.
Connection object of the present utility model is when drawing back state, the pipe position breach 116 of buckle 113 rear ends is in step 115 places, pipe position of fluting 112, elastic component 117 is in state of tension, buckle 113 is in lower position, when inwardly pushing away to fold the time, the projection 21 of outer rail 2 touches the projection button hole 114 on the buckle 113 and promotes buckle 113, make pipe position breach 116 break away from pipe position step 115, under elastic component 117 effects, buckle 113 is in step 115 tops, pipe position, projection 21 just enters projection button hole 114 and is lived by projection button hole 114 pipe clamps, and the connection object that is attached thereto like this is locked, can not be free to slide; When needs draw back, pulling connects object, make it to overcome elastic component 117 pulling force, when the pipe position breach 116 with buckle 113 is pulled to step 115 places, pipe position, buckle 113 has been located lower position by the higher position, projection 21 just breaks away from the constraint of projection button hole 114, and the connection object that is attached thereto unlocks, and can be free to slide; The utility model is simple in structure, and effectively locking connection object under collapse state makes it and can not be free to slide; And it is simple to unlock.
As preferred embodiment of the present utility model, elastic component 117 is a tension spring, and tension spring has better elastic and restoring force, and moderate, chooses easily.Buckle 113 front end upsides also are provided with anti-skidding mouthful 118, and anti-skidding mouthful 118 prevents when drawing back, and projection 21 breaks away from projection button hole 114 and the pipe position breach 116 of buckle 113 can not be pulled to pipe position step 115.Buckle 113 front end upper and lower sides are provided with angle position 119, can prevent that like this position, right angle produces bigger resistance in drawing process, make pulling smooth, and frictional force is little.
