Description
Technical field
The utility model relates to drawer sliding rail technical field more particularly to a kind of Self-locking drawer rail structures.
Background technique
Light-duty sliding rail is generally used in various light-duty drawer structures, such as file cabinet or other lesser drawers of load
In furniture.Existing drawer sliding rail generally can freely pull out push-in, for light-duty sliding rail, due to its load compared with
Small, resistance when drawer draws or is pushed into is also smaller, and the probability for occurring accidental switching off is bigger, it is easier to cause clamp hand accident.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of structure novel, are able to achieve to sliding rail
The Self-locking drawer rail structure positioned.
In order to achieve the goal above, the technical scheme adopted by the utility model is a kind of Self-locking drawer rail structure, packet
The outer rail being successively slidably connected from outside to inside, middle rail and internal rail are included, the cross section of the internal rail is in C-shaped configuration, including interior rail bottom
Face and two internal rail side walls, the internal rail bottom surface is rotatably connected to elastic locking bar, while the middle rail is provided with and protrudes from its inside
The locating piece in face；The V-shaped structure of the elasticity locking bar is simultaneously formed with spanner and strut, and the spanner and strut cooperation contradict in two
Trackside wall, wherein the spanner is also formed with front wedge and back wedge between the internal rail side wall that it is contradicted, and the front wedge is with after
There are the pitch spaces for cooperating the locating piece between voussoir, and the front wedge and back wedge are formed with and determine for guiding
Position block slides into the lead-in chamfered in pitch space.
Further, the locating piece takes shape on positioning glue, and the positioning glue is embedded in the middle rail.
Further, the shaft of the elastic locking bar is set between spanner and strut.
Further, the length of the spanner is greater than strut.
Further, the angle between the spanner and strut is directed toward internal rail tail end.
The beneficial effects of the utility model are: the utility model is after adopting the above structure, front wedge in elastic locking bar is utilized
Pitch space cooperation locating piece between back wedge can position internal rail.Specifically, when internal rail is drawn out to forward certain length
When, front wedge is contacted with locating piece, when internal rail pulls out further along, is guided by the lead-in chamfered of front wedge, spanner and support
Between angle diminution between bar makes front wedge avoid locating piece to make locating piece smoothly slide between front wedge and back wedge
The extension elongation of internal rail is set to be maintained at current state away from space.When internal rail is pushed into the locked state, user need to be using slightly
Big thrust pushes internal rail, and when pushing internal rail using slightly larger thrust, collide band dynamic elasticity between front wedge and locating piece
Deformation, which occurs, in locking bar reduces the angle between its spanner and strut, and locating piece skids off the sky of the spacing between front wedge and back wedge
Between, it is pushed into internal rail smoothly.When internal rail is pulled out disassembly in the locked state, needing to pull spanner manually makes spanner and strut
Between angle diminution so that back wedge is avoided locating piece, locating piece skids off the pitch space between front wedge and back wedge, make in
Rail pulls out disassembly by smooth.

Specific embodiment
The utility model technical solution claimed is made further specifically now in conjunction with the drawings and specific embodiments
It is bright.
Referring to shown in Fig. 1 to Fig. 3, the Self-locking drawer rail structure of the present embodiment includes successively being slidably connected from outside to inside
Outer rail 1, middle rail 2 and internal rail 3.
The cross section of internal rail 3 is in C-shaped configuration, including 3 side wall of 3 bottom surface of internal rail and two internal rails, 3 bottom surface of internal rail are rotatably connected to
Elastic locking bar 4, while middle rail 2 is provided with the locating piece 51 for protruding from its medial surface.In the present embodiment, locating piece 51 takes shape in
It positions on glue 5, which is embedded in the front end of the middle rail 2.
The V-shaped structure of elastic locking bar 4 is simultaneously formed with spanner 41 and strut 42, and spanner 41 and the cooperation of strut 42 contradict two internal rails
3 side walls, the shaft of elastic locking bar 4 is set between spanner 41 and strut 42 in the present embodiment, and the length of spanner 41 is big
Spanner 41 is arrived in strut 42 in order to which user is more easy-to-draw.Before the spanner 41 is also formed between its 3 side wall of internal rail contradicted
Voussoir 42a and back wedge 43b, there are the pitch space 44 for cooperating the locating piece 51 between front wedge 42a and back wedge 43b,
And front wedge 42a and back wedge 43b are formed with for guiding locating piece 51 to slide into the lead-in chamfered in pitch space 44
431.In the present embodiment, the angle between spanner 41 and strut 42 is directed toward 3 tail end of internal rail.
The elastic locking bar 4 of the present embodiment has front wedge 42a and back wedge 43b, and front wedge 42a and back wedge 43b
It is formed with lead-in chamfered 431, thus during so that internal rail 3 is pushed into or is pulled out, front wedge 42a or back wedge 43b and positioning
When touching, the angle between equal energy band wrench 41 and strut 42 reduces, between evacuation locating piece 51 is to make locating piece 51 slide into
Away from space 44.
The working principle of the sliding rail of the present embodiment is as follows: referring to fig. 4 and shown in Fig. 5, when internal rail 3 is drawn out to forward a fixed length
When spending, front wedge 42a is contacted with locating piece 51, when internal rail 3 pulls out further along, by the lead-in chamfered 431 of front wedge 42a
Guidance, the angle diminution between spanner 41 and strut 42 make front wedge 42a evacuation locating piece 51 to keep locating piece 51 smoothly sliding
Enter the pitch space 44 between front wedge 42a and back wedge 43b, the extension elongation of internal rail 3 is made to be maintained at current state.
Referring to shown in Fig. 6 and Fig. 7, when internal rail 3 is pushed into the locked state, user need to be pushed using slightly larger thrust
Internal rail 3, since the angle between spanner 41 and strut 42 is directed toward 3 tail end of internal rail, along with front wedge 43a is in internal rail length direction
On projection line deviate the shaft of elastic locking bar 4, therefore when pushing internal rail 3 using slightly larger thrust, front wedge 43a and locating piece
It collides between 51 and drives elastic locking bar 4 deformation occur to reduce the angle between its spanner 41 and strut 42, locating piece 51
The pitch space 44 between front wedge 43a and back wedge 43b is skidded off, is pushed into internal rail 3 smoothly.
Referring to shown in Fig. 8 and Fig. 9, when internal rail 3 is pulled out disassembly in the locked state, needing to pull spanner 41 manually makes
Angle diminution between spanner 41 and strut 42 makes back wedge 43b avoid locating piece 51, and locating piece 51 skids off front wedge 43a with after
Pitch space 44 between voussoir 43b makes internal rail 3 pull out disassembly by smooth.
The embodiment of the above is only the preferred embodiment of the utility model, not does any form to the utility model
On limitation.Anyone skilled in the art all can benefit in the case where not departing from technical solutions of the utility model ambit
More possible variations and retouching are made to technical solutions of the utility model with the technology contents of the disclosure above, or are revised as equivalent
The equivalent embodiment of variation.Therefore all contents without departing from technical solutions of the utility model, the thinking according to the utility model are made
Equivalent equivalence changes, should all be covered by the protection scope of the utility model.
