Description
Technical field
The utility model relates to a kind of furniture part, specifically the detachable steel ball drawer guideway of a kind of (drawer) for convenience detach.
Background technology
At present, the drawer of desk been has nearly all has been installed and used drawer lead rail device.Drawer guideway is because it has laborsaving, the advantage such as drawer push-and-pull is smooth-going and noise is low, very welcomed by the people, is widely used.
Existing a kind of drawer guideway, as shown in Figure 1, comprises outer guide (10) and interior guide rail (20), upper at outer guide (10), is provided with installing hole (11), pearl frame (12), ball (13) and end limited block (14); On interior guide rail (20), be provided with the spacing plush copper of installing hole (21) and end (22), between outer guide (10) and interior guide rail (20), be provided with anti-dropping device for drawer, described anti-dropping device for drawer forms by being arranged on the card convex portion (15) on outer guide (10) end limited block (14) and being arranged on the upper elasticity shift fork (23) being clasped with described card convex portion (15) of interior guide rail (20).When use, outer guide (10) is arranged on desk, interior guide rail (20) is arranged on drawer.When dismounting drawer, must be in pull-out drawer, the finger of two hands upwards draws or downward compression elasticity shift fork (23) along A direction respectively simultaneously, makes the bayonet socket disengaging card convex portion (15) of elasticity shift fork (23) pull out afterwards drawer again.Its weak point is that dismounting drawer is loaded down with trivial details, and novice can't disassemble drawer.
For the problems referred to above, the applicant once proposed a kind of detachable drawer guideway (as shown in Figure 2), publication number is 203328274U, its improvements are between outer guide (10) and interior guide rail (20), be provided with anti-dropping device for drawer, described anti-dropping device for drawer is by being arranged on the anticreep projection (16) on outer guide (10) end limited block (14) and being arranged on described interior guide rail (20) above and forming with the oblique conduction card convex (24) that anticreep projection (16) is clasped.When adjusting the height of oblique conduction card convex and adjust the gradient of dismantling inclined-plane, the size of pulling force when just drawer is taken out in capable of regulating dismounting.Described technical scheme is adapted to the good drawer assembling of quality of fit of drawer and cabinet.But in the time that the quality of fit of drawer and cabinet is poor, the performance reliability of anti-dropping device for drawer will be difficult to guarantee.
Summary of the invention
The utility model, is intended to the improvement to existing drawer guideway, and the detachable steel ball drawer guideway of another kind of version is provided.
The utility model, comprise outer guide and interior guide rail, on outer guide, be provided with installing hole, pearl frame, ball and stopper protrusion, on interior guide rail, be provided with the spacing plush copper in installing hole and end, on the pearl groove of the two side of outer guide outer end, be provided with necking part, every side retraction degree of depth of necking part is 1-5mm, and the distance of necking part center and outer guide outer face is 5-30mm.
The utility model, the bottom that described stopper protrusion ties up to outer guide forms through hardware stamping.
The utility model, in the spacing plush copper in the end of described interior guide rail, is provided with concavo-convex reinforcement.
The utility model, there is following good effect: (1) is owing to being provided with necking part on the two side pearl groove in described outer guide outer end, in the time that drawer is drawn out to as Fig. 3 position outward, the limited protuberance 17 of pearl frame 13 limits, outer end two to ball respectively necking portion compress, the sidewall pearl groove by the internal guide rail of ball is produced resistance to compression pression by outer guide, in stoping, guide rail continues to move outward, in the time that interior guide rail pulling force is outward greater than described resistance to compression pression, drawer will be drawn out, and reach the object of just tearing open.In other words, in the time will dismantling taking-up drawer, drawer is pulled out, reach the object of (drawer) for convenience detach.By the degree of depth of every side retraction of control and regulation necking part, regulate the pulling force of drawer dismounting.(2) adopt the stopper protrusion forming through hardware stamping to replace original plastics block, there is the advantages such as simple in structure, never drop-off, and manufacturing cost is lower.The effect of stopper protrusion is the spacing of the location of interior guide rail and outer guide pearl frame.(3), in the spacing plush copper of the outer end of interior guide rail, the concavo-convex reinforcement of setting, its role is to strengthen the mechanical strength of spacing plush copper.
