Abstract
The invention belongs to the technical field of refrigerator door body tools and particularly relates to an automatic closing device for a refrigerator door body. The automatic closing device for the refrigerator door body comprises spring steel. The upper end of the spring steel is connected with a torsion adjustor. The torsion adjustor comprises a central shaft. A fixing ring is fixedly connected to the central shaft. A plurality of clamping grooves are formed in the two ends of the fixing ring. Clamping teeth are arranged between the adjacent clamping grooves. The clamping teeth and the clamping grooves are in transition through inclined faces. An upper swivel is connected to the upper end of the fixing ring. An upper spring is connected to the upper end of the upper swivel. A lower swivel is connected to the lower end of the fixing ring. A lower spring is connected to the lower end of the lower swivel. The upper end of the spring steel is inserted in the central shaft to abut against the lower spring. The upper swivel and the lower swivel are fixedly connected with the refrigerator door body. A shaft fixing block is connected to the other end of the spring steel. The shaft fixing block and the refrigerator door body are fixed together through hinges. The automatic closing device for the refrigerator door body has the beneficial effects that when people forget to close the refrigerator door body or the force for closing the refrigerator door body is insufficient, the refrigerator door body can be automatically closed, and therefore a refrigerator can be normally used.
Description
Technical field
The invention belongs to refrigerator door apparatus technical field, particularly relate to a kind of refrigerator door automatic closing device.
Background technology
The refrigerator door of current use is all generally retractable structure, namely by manually opening refrigerator door, after then taking out thing, at artificial closed refrigerator door.But, when reality uses, take out thing from refrigerator after, often forget closed refrigerator door or dynamics is inadequate when closed refrigerator door, make the closed imprecision of refrigerator door, thus the temperature of refrigerator inside can be affected, bad effect is produced for the article being placed on refrigerator inside.
Summary of the invention
The object of the invention is to solve above-described technical problem, there is provided a kind of forget close refrigerator door or closed refrigerator door dynamics inadequate in, refrigerator door can realize closing automatically, and make the refrigerator door automatic closing device that refrigerator can normally use, its technical scheme is as follows:
Refrigerator door automatic closing device, it is characterized in that, described refrigerator door automatic closing device comprises spring steel, the upper end of described spring steel is connected with torsion adjuster, torsion adjuster comprises axis, axis is fixed with retainer ring, the two ends place of retainer ring is provided with some draw-in grooves, latch is provided with between adjacent draw-in groove, chamfered transition is passed through between latch and draw-in groove, the upper end of retainer ring is connected with change, the upper end of described upper change is connected with spring, the lower end of described retainer ring is connected with lower change, the lower end of described lower change is connected with lower spring, it is inconsistent that the upper end of spring steel is inserted into axis up and down spring, described upper change and lower change and refrigerator door are fixedly linked, the other end of described spring steel is connected with axle fixed block, and described axle fixed block and Refrigerator door hinge are fixed.
Preferred embodiment is, described axis offers holddown groove, is provided with spring shim in described holddown groove, and spring shim contacts with one end of upper spring and lower spring.
Preferred embodiment is, the top end of described axis offers adjustment hole.
Refrigerator door automatic closing device provided by the invention, when in use, spring steel produces to reply pretightning force effect, and refrigerator door after opening spring steel produces reply pretightning force, and then under the effect of replying pretightning force, refrigerator door closes automatically.Torsion adjuster is that spring steel is twisted, thus makes spring steel produce reply pretightning force.Upper change and lower change are for coordinating refrigerator door body.Axle fixed block is for coordinating refrigerator door body.
The further axis of the present invention offers holddown groove, is provided with spring shim in described holddown groove, spring shim contacts with one end of upper spring and lower spring.By holddown groove and spring shim, spring can better be operated.
The top end of the axis that the present invention is further described offers adjustment hole.By the torque magnitude that adjustment hole can regulate torsion adjuster to produce, thus carry out the size of the reply pretightning force that regulating spring steel produces.
The invention has the beneficial effects as follows: forget close refrigerator door or closed refrigerator door dynamics inadequate in, refrigerator door can realize closing automatically, and refrigerator can normally be used.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the schematic diagram of torsion adjuster.
Fig. 3 is the schematic diagram of retainer ring.
Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1 to Fig. 3:
As shown in Figure 1 to Figure 3, refrigerator door automatic closing device, described refrigerator door automatic closing device comprises spring steel 1, the upper end of described spring steel 1 is connected with torsion adjuster 2, torsion adjuster 2 comprises axis 3, axis 3 is fixed with retainer ring 4, the two ends place of retainer ring 4 is provided with some draw-in grooves 41, latch 42 is provided with between adjacent draw-in groove 41, by inclined-plane 43 transition between latch 42 and draw-in groove 41, the upper end of retainer ring 4 is connected with change 5, the upper end of described upper change 5 is connected with spring 6, the lower end of described retainer ring 4 is connected with lower change 7, the lower end of described lower change 7 is connected with lower spring 8, it is inconsistent that the upper end of spring steel 1 is inserted into axis 3 up and down spring 8, described upper change 5 and lower change 7 are fixedly linked with refrigerator door, the other end of described spring steel 1 is connected with axle fixed block 9, and described axle fixed block 9 is fixed with Refrigerator door hinge.
Preferred embodiment is, described axis 3 offers holddown groove 10, is provided with spring shim 11 in described holddown groove 10, and spring shim 11 contacts with one end of upper spring 6 and lower spring 8.
Preferred embodiment is, the top end of described axis 3 offers adjustment hole 12.
When concrete use, time refrigerator door is opened, axis drives retainer ring to rotate, and in time turning to certain angle, the profile of tooth matching mechanism of upper change and lower change and fixed block, makes the latch of fixed block can coordinate with upper change and lower change.Now, the rotation due to axis makes spring steel twist, and spring steel creates reply pretightning force.After external force disappears, reply pretightning force generation effect, refrigerator door is closed.What can regulate axis by adjustment hole turns to diverse location, thus regulates different reply pretightning forces.
