Abstract
The utility model discloses a plunger type fastener comprising a cover plate (1), a base (2), plungers (3) and screws (4). The cover plate (1) is a rectangular sheet with a notch at the upper edge. The base (2) is of a box structure and provided with slots. The plungers (3) are spring plungers (3) with external threads. During working of the plunger type fastener, a to-be-fastened device (5) is placed in a cavity formed by the base (2) and the cover plate (1), ball heads of the plungers (3) are stressed after the to-be-fastened device (5) is in contact with the ball heads of the plungers (3) on two sides, then springs in the plungers (3) are compressed, the distance between the ball heads of the two plungers (3) is increased until the to-be-fastened device (5) passes through the plungers (3), and further, the plungers (3) release the amount of compression, the distance between the ball heads of the two plungers(3) is reduced, so that the to-be-fastened device (5) is fastened. The plunger type fastener is convenient to change and maintain. As the distance between the plungers is adjustable, the fastener has wider application range.

Background technique
At present, existing buckle consists of flat board, housing and metal spring leaf.Metal spring leaf is welded on housing, during use, metal spring leaf bend by pressure is clamped on equipment on housing, but metal spring leaf is for a long time in flexural loading state, the weld strength of destructible metal spring leaf and housing, repeatedly take out or during place apparatus, metal spring leaf easily produces flexural fatigue surrender, thereby permanent deformation increases with body clearance, can not clamping equipment, reliability is low; Metal spring leaf and housing adopt assemble welding, are not easy to maintenance; And this buckle can only clamp fixed-size equipment, Applicable scope is little.
Model utility content
The purpose of this utility model is to provide a kind of plug type buckle, solves the current problem that buckle reliability is low, Applicable scope is little.
A plug type buckle, comprising: cover plate, base, plunger, screw.Cover plate is rectangular thin plate, thickness is 1.5mm ~ 2.5mm, all there is countersunk head round tube hole at four angles of cover plate, the diameter of four countersunk head round tube holes is 2.5mm ~ 3.5mm, and the coboundary of cover plate is jagged, and breach left and right is placed in the middle, be " Y " font, breach topmost width is 35 ~ 45mm, and two hypotenuses of " Y " font of breach are 90 ° of angles, and the parallel vertical edge width of " Y " font lower half portion of breach is 10mm ~ 15mm.Base is rectangular structure, the width of base is identical with the width of cover plate, on base, there is groove, groove left and right is placed in the middle and form breach with base coboundary, the shape of groove is " Y " font, and the overall size of groove is greater than cover plate " Y " font breach overall size, and the top width of groove is 45mm ~ 55mm, two hypotenuses of " Y " font of groove are 90 ° of angles, and the parallel vertical edge width of " Y " font lower half portion of groove is 15mm ~ 25mm.There is symmetrical tapped hole at sidewall middle part, base left and right, and tapped hole communicates with groove.There is boss at base lower boundary place, and the height of boss is identical with cover sheet thickness, and all there is tapped hole at four angles of base, and four tapped holes of base are identical with the position of four countersunk head round tube holes of cover plate.Screw is placed in the countersunk head round tube hole of cover plate and the tapped hole of base, makes cover plate and base fastening, and the top of cover plate and base forms cavity, and cover plate is concordant with coboundary, left side wall, the right side wall of base.Respectively there is a counter sink above and below of base, and diameter is 3mm ~ 5mm.Plunger is outside screw type spring-loaded plunger, and plunger head is spherical, and plunger external thread diameter is identical with the tapped hole diameter of base both sides, and plungers length is 10mm ~ 20mm.
During the work of plug type buckle, will be placed in by card apparatus the cavity that forms of base and cover plate, two plungers screw in base by the tapped hole of base both sides, and the bulb spacing of two plungers is set by pilot plunger screw-in depth, after being contacted with both sides plunger ball by card apparatus, plunger ball pressurized, plunger inner spring starts compression, and two plunger ball spacing increase, until passed through plunger by card apparatus, plunger discharges decrement, and two plunger ball spacing reduce, and clamping is by card apparatus.The counter sink of base above and below is for being fixed on plug type buckle in other devices.
All by being threaded, there is not the problem that weld strength is inadequate in the utility model, and changes conveniently, is convenient to maintenance; After equipment is clamped, both sides plunger decrement discharges, and camber of spring is little, has guaranteed the intensity of plunger, has improved reliability; Plunger spacing can regulate, and makes buckle Applicable scope large.
