Abstract

The utility model provides a hinge with small size and long service life. The utility model comprises a fixed part and a rotary part. The fixed part comprises two vertical-plates which are arranged oppositely. The upper ends of the vertical-plates are formed a rotary connection with the rotary part through a rotary shaft. A movable shaft parallel to the rotary shaft is arranged on the rotary part. A limited plate with a pilot hole is connected between the lower ends of the vertical-plates. The upper end of a swing shaft which passes through the pilot hole is connected to the movable shaft in the rotary way. A spring which can cause the swing shaft to generate a movement trend from top to bottom along the axis direction under the normality is arranged between the swing shaft and the limited plate. The lower end of the swing shaft is provided with a limited block which is bigger than the pilot hole.

Description

A kind of hinge

Technical field

The utility model relates to a kind of hinge, especially is applied in the hinge on the refrigerator-freezer.

Background technology

Existing refrigerator-freezer hinge comprises fixture, tumbler, and fixture comprises two risers that are oppositely arranged; The upper end of two risers and tumbler are rotationally connected by a rotating shaft; Moving axis with shaft parallel is set on the tumbler; Connect the limiting plate that has pilot hole between the lower end of two risers; The swinging axle upper end of passing pilot hole is rotatably connected on the moving axis, the two ends of moving axis stretch into respectively on two risers, opened, be in the deep-slotted chip breaker in the center of circle with the rotating shaft; Be provided with between swinging axle and the limiting plate swinging axle is produced along its axial spring of movement tendency from bottom to top.Rotate (swing) when tumbler is equivalent to fixture around the shaft, moving axis promptly slides in deep-slotted chip breaker.The contacted position of moving axis and deep-slotted chip breaker promptly is that tumbler is equivalent to the extreme position that fixture rotates.Existing hinge is opened on two risers because of limiting the deep-slotted chip breaker that tumbler is equivalent to the fixture turned position, so riser will have certain height (generally being not less than 30mm), so its size is bigger, has wasted material.

Although people want deep-slotted chip breaker is removed to reduce the size of riser, remove deep-slotted chip breaker after, can't be spacing when tumbler is equivalent to fixture and rotates.Therefore, people just want to limit the turned position that tumbler is equivalent to fixture by other position limiting structure.But limit the turned position by other position limiting structures, effect is all undesirable.This is because when tumbler turns to extreme position with respect to fixture, position limiting structure will play the effect that tumbler is stopped operating, the elastic force that adds upper spring, the active force that position limiting structure is subjected to is very big, position limiting structure will damage after being subjected to repeatedly impacting, application life is shorter, generally about 2000 times.

Summary of the invention

The purpose of this utility model provides the hinge of the less and long service life of a kind of size.

This hinge comprises fixture, tumbler, and fixture comprises two risers that are oppositely arranged; The upper end of two risers and tumbler are rotationally connected by a rotating shaft; Moving axis with shaft parallel is set on the tumbler; Connect the limiting plate that has pilot hole between the lower end of two risers; The swinging axle upper end of passing pilot hole is rotatably connected on the moving axis; Be provided with between swinging axle and the limiting plate swinging axle is produced along its axial spring of movement tendency from bottom to top; The swinging axle lower end is provided with the limited block greater than pilot hole.

The utility model is with respect to the improvement of existing hinge, the former deep-slotted chip breaker of opening on two risers is removed, and in the swinging axle lower end limited block greater than pilot hole is set.When tumbler rotated around the axis (swing) with respect to fixture, moving axis promptly rotated around the axis (swing) because swinging axle one end is connected on the moving axis, on one side swinging axle swing, Yi Bian it axially moves up in the elastic force effect lower edge of spring.When the limited block of swinging axle lower end contacted with limiting plate, swinging axle just can not axially move up along it, and tumbler just can not be rotated further.This has promptly reached limit function.This hinge dimensions is less, and the height of two risers can be at 20-25mm; Through fatigue test, access times are more than 20000 times.

The specific embodiment

Below in conjunction with its structure of description of drawings and operating principle.Fixture 1 comprises two risers 101 that are oppositely arranged; Two risers 201 of the upper end of two risers and tumbler 2 are rotationally connected by a rotating shaft 12.Moving axis 7 with shaft parallel is set on the tumbler.The limiting plate 3 that becomes to removably connect and have pilot hole 301 by bolt between the lower end of two risers; Swinging axle 4 upper ends of passing pilot hole are rotatably connected on the moving axis 201.Be provided with between swinging axle 4 and the limiting plate 3 swinging axle is produced along its axial helical compression spring 34 of movement tendency from bottom to top; Stage clip 34 is sleeved on the swinging axle, and its two ends contact with limiting plate, swinging axle respectively by two coordinating blocks 5.Swinging axle 4 lower ends become the limited block 6 be removably connected with greater than pilot hole 301 by bolt.

Use is on refrigerator-freezer the time, and fixture 1 is connected on the cabinet rear wall of refrigerator-freezer by the 102 usefulness bolts of the connecting hole on it.Tumbler 2 is connected on the rear wall of freezer cover by the 202 usefulness bolts of the connecting hole on it.As shown in Figure 1, limited block 6 does not contact with limiting plate 3 when normality; And rotating shaft 12 is not on the axis of swinging axle 4, and 34 pairs of swinging axles of stage clip 4 produce active force, and this active force acts on the freezer cover by tumbler, makes freezer cover tightly be pressed on the cabinet of refrigerator-freezer, and refrigerator-freezer becomes to cover state.

When opening freezer cover, freezer

cover drives tumbler

2 and 12 rotates (swing) around the shaft, and moving axis 7 promptly 12 rotates (swing) around the shaft, and swinging axle was done swing simultaneously and moved along its axis motion this moment.When opening freezer cover and reach certain angle, referring to Fig. 2, limited block 6 contacts with limiting plate 3; And rotating shaft 12 is not on the axis of swinging axle 4, and 34 pairs of swinging axles of stage clip 4 produce active force, and this active force acts on the freezer cover by tumbler, makes freezer cover remain on certain position, and refrigerator-freezer becomes open mode.
