Description

A kind of drawer anti-skidding position-limit mechanism

Technical field

The utility model relates to a kind of stopping means, particularly a kind of have stop drawer to skid off the drawer anti-skidding position-limit mechanism of function automatically.

Background technology

At present in portable tool box, the locker of used some the band drawers of motor vehicle, desk, very convenient owing under unlock state, can arbitrarily pulling out when using, but the anti-jitter poor ability of this drawer, be easy to skid off, after skidding off, drawer can cause toppling over of whole cabinet, thereby functional reliability, security are all very poor, only should be used in the stable environment.Skid off, improve the job security of drawer for the accident that prevents drawer, usually adopt traditional key matched locking mechanism locked drawer, but this mode that must use key to lock and to open, there are many trouble parts during use, and in a single day the user forget the pinning drawer, and security incident also can meet accident.In recent years, occur exempting from the drawer anti-skidding locking mechanism of key on the market, broken away from the trouble of using key, bring ease of use, but the most structure more complicated of these anti-skidding locking mechanisms, some cost price even surpass the cost of lock is so consider to owe ideal from the economy angle.

Summary of the invention

The purpose of this utility model is will provide a kind of can not only be completely free of the trouble of using key to open drawer, and simple in structure, cost is low, have to automatically lock and rely on the unlock novel drawer anti-skidding position-limit mechanism of function of manual control.

Drawer anti-skidding position-limit mechanism of the present utility model is mainly by spacing pin, key seat, self-plugging rivet, the compression spring, joystick and spacing buckle constitute, be characterised in that spacing pin, key seat, self-plugging rivet, compression spring and joystick are arranged in " Contraband " shape groove of strip drawer handle plate, spacing buckle be fixedly installed on the corresponding box side in the anterior mouth position, circular hole edge of key seat on, wherein: described spacing pin main body is strip, the shouldered pin tongue that is wedge shape by circular pin rod and leading section constitutes, and is set with described joystick on the tail end of circular pin rod; In the middle of described key seat main body is a lateral surface of rectangular strip, the leading section of band circular hole be provided with the described same side of buckle, caudal part being installed with the outer gibbosity of spacing catching groove be provided with in the fixed mounting of band pilot hole, band and the described circular pegs shank diameter inside dogging shoulder of installing hole that is complementary in the tail end circular orifices is provided with; Described spacing buckle is provided with spacing button hole.

Under installment state, drawer anti-skidding position-limit mechanism of the present utility model is arranged in " Contraband " shape groove of strip drawer handle plate, the spacing catching groove button that key seat leading section outer gibbosity is installed on the buckle is held on the side of drawer panel, and be arranged on drawer panel by on the desired location of casing one side by the fixing assembling of self-plugging rivet by the pilot hole on the key seat caudal part fixed mounting, spacing pin integral body is stretched and is put in the middle circular hole of key seat, the compression spring is spacing by the inside dogging shoulder of shouldered pin tongue and key seat tail end circular orifices, suit is arranged on the circular pin rod of spacing pin, and fixing assembling is provided with joystick on the overhanging tail end of spacing pin circular pegs bar simultaneously; Spacing buckle is fixedly installed on the corresponding box side of its spacing button hole and the anterior mouth position, circular hole edge of key seat.

During work, under the situation of no external force effect, the compression spring is in unfolds state, and joystick is subjected to card by being held on the key seat tail end, and spacing pin is at its overhanging state in triangular belt cotter pin tongue place under the effect of the mobile thrust of the anterior circular hole edge mouth of key seat; During tension state, the triangular belt cotter pin tongue on the spacing pin leading section contacts with the spacing buckle on the casing side outside drawer is in, and when shifting position, triangular belt cotter pin tongue in the drawer onto and align with spacing button hole on the spacing buckle, promptly goes into padlock automatically calmly; When needs are opened drawer, as long as spur handle in the other direction, can drive spacing pin displacement with hand, triangular belt cotter pin tongue is withdrawed from from spacing button hole, realize release.

The utility model drawer anti-skidding position-limit mechanism based on above-mentioned design, because what play the prime move effect during work is compression spring and joystick, and the compression spring is arranged on the circular pin rod of spacing pin with the form suit of limit shaft dress, be in nature during work and uphold in an orderly manner or compressive state, can not take place to cause the situation that influences functional reliability and safety in utilization because of spring breakage; During installation, only need a limit notch to be set on the drawer panel edge, a spacing rivet hole is set on drawer panel, drawer anti-skidding position-limit mechanism of the present utility model can be arranged in " Contraband " shape groove of drawer handle plate, very convenient; And the general structure part is few, wherein self-plugging rivet and compression spring are that standard can be purchased part, drawer handle plate, spacing buckle are the basic building block of drawer and casing, only spacing pin, key seat and joystick are special parts, and structure is all very simple, easy to process, so production cost is extremely low, in addition also lower than the cost of normally joining lock, and install and use all convenient, reliable operation and safety, use on the drawer of the mobile big and relatively poor occasion of environmental stability of the work that is suitable for especially.
