Abstract

The utility model relates to a door bolt structure which is composed of a door body, a door hook and a door shaft journal which are connected with the door body by screws, and a door bolt which is tightly connected with the door body by punching; in the process of rotation (or movement) of the door body, the plastic door hook and the circular door bolt conduct the activating collaterals connection to realize the function of latching the door. The utility model has the advantages of low processing cost and long service life. The utility model can be used for boxes and cabinet doors of refrigerators, disinfecting cabinets, microwave ovens, etc.

Description

Door bolt mechanism

The utility model relates to mechanical connection component technology field, the suitable especially door bolt mechanism as case, cabinet.

In existing door bolt mechanism, especially use on the refrigerator by door-hinge pivot and be arranged in the door bolt mechanism that the plastics gate stop on the body is formed, the door-hinge pivot is because of the difference of processing method, technology, or cold punching or cold-heading.The former is as Mitsubishi series refrigerator product, and its door-hinge pivot adds essence again and dashes behind cold punching; The latter such as Haier's series refrigerator product, its door-hinge pivot adopts cold heading technique.That both required process equipments require is high (press capacity big or through secondary operations), thereby relative cost is also just higher; Otherwise, in the refrigerator product of other trade mark, also have and adopt a cold punching technology, decrease though compare cost with the former like this because on the door-hinge pivot after the punching out, there is certain otch burr, with plastics gate stop connection procedure in, because of being in contact with one another friction, the plastics gate stop very easily weares and teares, and loses the bolt function gradually, is unfavorable for the sealing of chamber door like this.That is to say the application life that has influenced door bolt mechanism.In sum, in the door bolt mechanism of existing structure,, there are defectives such as cost higher or application life is short because of the restriction of the processing technology of door-hinge pivot.

The purpose of this utility model is to propose a kind of novel structure, eliminates some deficiency that exists in the prior art, to reach the application life that can improve door bolt mechanism, does not increase the purpose of processing cost again.

The utility model is done following further describing in conjunction with the accompanying drawings:

Fig. 1 is a kind of structure chart of existing door bolt mechanism

Fig. 2 is a kind of door bolt mechanism structure chart that the utility model proposes

Fig. 3 is a kind of door bolt mechanism fundamental diagram that the utility model proposes

A kind of door bolt mechanism is formed (in conjunction with the accompanying drawings 2 explanations) with it as the door bolt 3 that close-fitting is connected with door-hinge 4 and through punching 5 through the gate stop 2 that screw is connected by door body 1 and with it; Gate stop 2 on the door body 1, when arriving certain angle (or distance) with the rotation (or moving) of door body 1, gate stop 2 just contacts with door bolt 3, behind the dead point that has overcome gate stop 2 geometries, gate stop 2 relies on the elasticity of himself to slip into dead angle area automatically, gate stop 2 is closely contacted with door bolt 3, promptly finish the action of bolting the door; Otherwise after external force overcame dead band and the living active force of gate stop 2 bullets, a door body 1 automatically springed open (3 explanations in conjunction with the accompanying drawings).

A kind of door bolt mechanism embodiment that the utility model proposes structurally uses circular door bolt, substitutes the notch portion of the door-hinge pivot pressing product in the prior art door bolt mechanism, and with do active the connection with the gate stop of plastic production, the realization function of bolting the door.Because door bolt is circular smooth and enough vertical height are arranged, make itself and the contact surface increase of plastics gate stop; Simultaneously, significantly reduced itself and the latter's frictional dissipation.Therefore, under the condition that does not change a flushing technology, improved the application life of door bolt mechanism,, provide the technology material guarantee for improving the refrigerator product whole service life.

In view of the above, can draw inferences about other cases from one instance, a kind of door bolt mechanism that the utility model proposes except using on refrigerator product, also can be implemented on the case of household electronic products such as disinfection cabinet, micro-wave oven, cabinet door.

Claims

A kind of door bolt mechanism of being formed by door body, gate stop, door bolt and door-hinge pivot, it is characterized in that: gate stop (2) fixes with door body (1) through screw and is connected, door bolt (3) is connected as close-fitting through punching (5) with door-hinge pivot (4), does active the connection by the gate stop (2) on the door body (1) of activity with door bolt (3).
