Abstract

A positioning and forced drawing device of drawer track comprises an inner track with a baffle protruded on the inner groove at back, while the baffle is inclined toward end and vertically connected with the inner groove, a middle track which can slide relative to the inner track and arrange a flexible frame at back end, a frame hole at center, and two frame wings at two sides, while the frame hole is not smaller than the baffle, the frame wings have arc chamfered angles at two top ends, and an outer track which can slide relative to the upper track with a concave flange at back. When in push, the concave flange clamps the flexible frame, the flexible frame can be baffled to position the drawer, and when in pull, the flexible frame leaves the flange to return back, to release baffle force from the flexible frame.

Description

The location of drawer sliding rail and pressure pulling off device

Technical field

The utility model relates to a kind of drawer sliding rail, relates in particular to a kind of location and pressure pulling off device of drawer sliding rail.

Background technology

Drawer has finding more in people's life, such as furniture, desk, cabinet ... Deng, all see the existence of drawer, to trace it to its cause, it can pull out or push in order to the content product in addition, thus long lasting, its irreplaceable role playing is arranged in fact.

And the formation of drawer is the open box body in a top, and the one side is linked to slide rail, then, this slide rail then is linked to the inwall between the drawer that furniture reserves, therefore, when the pulling drawer, the then operation of slide rail can be drawer and pushes or pull out, and for the occasion than big drawer, then take the mode of three-sectional or three slide rails, rail in promptly coating, the mode of rail in middle rail coats again with outer rail, make each adjacent slide rail slippage mutually, think pulling out and pushing of drawer.

In fact, drawer often must be by positioner with the location, in order to avoid it skids off automatically when being pushed into the bottom, and if the too tight or firm order of positioner is solid, then towing tension is bigger when pulling out, the sensation of having some setbacks for the people, therefore, how to design a location and well and again can force the slide rail of pulling out, be the problem that the dealer pursues, especially aforementioned three slide rails and time spent, its difficulty is high more.

The utility model content

The purpose of this utility model is to provide a kind of location and pressure pulling off device of drawer sliding rail, can make the location of drawer sliding rail and pull out more practicable.

For achieving the above object, the location of the drawer sliding rail that the utility model provides and pressure pulling off device, it comprises:

Rail in one, the prominent backstop of establishing on its back side inside groove, this backstop vertically are linked to inside groove after oblique in the end place;

Rail in one is a slip with respect to interior rail, and its end place, back side establishes a resilient bezel, and then each prominent establishes a frame wing for central tool one frame hole, both sides, and the size in frame hole is not less than backstop, place, the two ends top tool arc angling of the frame wing;

One outer rail is a slip with respect to middle rail, the edge clipping of tool one depression on its back side;

After when pushing, pressing resilient bezel by the edge clipping of depression, but resilient bezel clip backstop forming the location, but when extracting out, resilient bezel breaks away from edge clipping resilience then, makes backstop also can break away from the clip of resilient bezel.

Interior rail wherein, middle rail and outer rail are metal material.

Description of drawings

For further specifying concrete technology contents of the present utility model, at first see also accompanying drawing, wherein:

Fig. 1 is a schematic perspective view of the present utility model;

Generalized section when Fig. 2 is location of the present utility model;

Profile when Fig. 3 pulls out for pressure of the present utility model.

The specific embodiment

As shown in the figure, basically, slide rail of the present utility model is made up of a rail 2 and an outer rail 3 in the interior rail 1.

Wherein, interior rail 1 is outermost slide rail for coating and pull out the back, and it simultaneously goes up the device of tool and the binding of drawer box body, this is known skill, do not intend money and state, and creation of the present utility model place, for as shown in Figure 1 in other face, promptly with after chat in rail 2 mutually on the inside groove 11 of slippage, the prominent backstop 12 of establishing, this backstop 12 oblique mode in the end place can be clip with it, and its forming method, the mode of rail 1 in then can being linked to by integrated punching or with other part.

Middle rail 2 is the stage casing slide rail, its with respect to rail 1 in aforesaid and after the outer rail 3 chatted, can be by the side direction ball to slide, this is a known technology, thus do not intend giving unnecessary details, and rail 2 is in the end place in of the present utility model, the prominent resilient bezel 21 of establishing, claiming resilient bezel 21, is to be tool elasticity for middle rail 2, and it can be the integrated punching moulding, also can be other part and be located at middle rail 2, and its central authorities, both sides, then tool one frame hole 211, and outer rim are to the upper process frame wing 212, its two ends are that arc angling is modified, the size in this frame hole 211 is greater than aforesaid backstop 12, can ccontainingly locating.

Outer rail 3 is for coating aforesaid middle rail 2, and its front end then strikes out V-type edge clipping 31 downwards corresponding to aforementioned resilient bezel 21 places, and the edge line 311 of the central part of edge clipping 31 height is a minimum point, and is the gesture of rising forwards, backwards.

Please consult accompanying drawing again, the utility model is when implementing, when desiring to push, when then drawer pushes away before together with interior rail 1, backstop 12 front ends can be pushed resilient bezel 21 and raise up, and when pushing, then backstop 12 embeds the frame hole 211 of resilient bezel 21 again, and continue to move ahead, then backstop 12 can be subject to the edge clipping 31 of outer rail 3 and press down and enter outer rail 3, and after resilient bezel 21 is passed through edge line 311, promptly forms the location, rail 1 in this moment, middle rail 2 promptly can't move outward.

And when desiring to pull out drawer, then twitch drawer box, and resilient bezel 21 breaks away from edge clipping 31 because of drawing outward, and then resilient bezel 21 resiliences this moment, backstop 12 can be passed through resilient bezel 21, and like this, drawer box promptly can be and pulls out.

The just preferred embodiment that the utility model is lifted a kind of, such as Ju Bu change or modification and come from this real technological thought and be have the knack of this technology the people was easy to know by inference, all do not take off patent right category of the present utility model.

Claims

1, a kind of location of drawer sliding rail and pressure pulling off device, it comprises:
