Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.
As Figure 1-Figure 2, the present embodiment has the hinge component of auto-lock function, including first axle portion 1, second hinge
Portion 2 and sleeve 3, the first axle portion 1 and the second hinge portion 2 are hinged by shaft 10, the second hinge
Portion 2 is slidably connected in the sleeve 3；The shaft 10 is located at the outside of the sleeve 3 under rotatable state, in locking shape
The first axle portion 1 connects the end of the shaft 10 and is inserted in the sleeve 3 under state.
Specifically, first axle portion 1 passes through shaft 10 and second in hinge component of the present embodiment with auto-lock function
2 hinged formation hinge arrangement of hinge part, first axle portion 1 can be rotated relative to second hinge portion 2, and second hinge
Portion 2 can slide in sleeve 3.In actual use, when the hinge component reality for needing the present embodiment that there is auto-lock function
During the function of now rotating, then first axle portion 1 is lifted, second hinge portion 2 slides in and out in sleeve 3 so that shaft 10 is exposed
In the outside of sleeve 3, first axle portion 1 is rotated relative to second hinge portion 2 without being limited by sleeve 3 by shaft 10；And
When need to lock first axle portion 1 prevent it from rotating when, then it is coaxial to rotate first axle portion 1 and second hinge portion 2, and presses
First axle portion 1 causes the end for being connected with shaft 10 to be located in sleeve 3, and under the constraint of sleeve 3, first axle portion 1 will
It is limited in sleeve 3 and can not be rotated relative to the second articulated section 2, so as to fulfill the function of locking, and in the locked state,
Sleeve 3 can provide reliable support force to first axle portion 1, not influenced by the power on 3 direction of sleeve, reliability
It is higher.Preferably, the upper end of sleeve 3 is also threaded with stiffnut 31, and stiffnut 31 can effectively improve sleeve 3
Port at structural strength, after being limited in sleeve 3 in first axle portion 1, stiffnut 31 can be to being inserted with first
External structure reinforcement is played the role of in the port of hinge part 1, so as to provide first axle portion 1 support force of bigger.
Further, the second hinge portion 2 is provided with piston rod 21, and limiting cylinder body 31, institute are provided in the sleeve 3
State piston rod 21 be slidably connected at it is described limiting cylinder body 31 in form piston cylinder structure.Specifically, pass through piston rod 21 and limiting
Cylinder body 31 cooperatively forms piston cylinder structure, and in use, the piston head of piston rod 21 slides in cylinder body 31 is limited, so as to
The sliding stroke in second hinge portion 2 can be limited, second hinge portion 2 is avoided to be detached from sleeve 3, improves use reliability.
Preferably, in order to facilitate user in actual use, first axle portion 1 is lifted out, is additionally provided in limiting cylinder body 31 slow
Rush spring（It is not shown）, the buffer spring be arranged on it is described limiting the cylinder bottom of cylinder body 31 and the piston rod 21 between.Specifically
, for having the present embodiment the hinge component of auto-lock function to be applied on refrigerator, first axle portion 1 connects the guarantor of refrigerator
After thermal insulating door thermally insulated door is opened, under the effect of gravity, first axle portion 1 is pressed into sleeve 3 by Wen Men, and user needs to close heat preservation
Men Shi, by designing the elastic force of buffer spring, to offset the gravity of thermal insulating door thermally insulated door by spring force, more convenient user will keep the temperature
Door, which upgrades, completes door-closing operation, improves ease of use.
Further, inclined surface is formed on the end that the first axle portion 1 is connect with the second hinge portion 2
11, the side of the inclined surface 11 forms the limiting section for limiting the first axle portion rotation（It is not shown）.It is specifically, logical
Inclined surface 11 will be formed by crossing in first axle portion 1, inclined surface 11 will cause first axle portion 1 to form the end that side outwardly protrudes
That is limiting section, limiting section can first axle portion 1 relative to in 2 rotation process of second hinge portion, to first axle
The rotational angle in portion 1 is limited, when first axle portion 1 is turned to it is coaxial with the second hinge portion 2 when, limiting section will be against
In second hinge portion 2, it is rotated further so as to limit first axle portion 1.Wherein, inclined surface 11 is globoidal structure, to realize
During first axle portion 1 rotate in place, buffering is played the role of in inclined surface 11.
As Figure 3-Figure 4, the present invention also provides a kind of refrigerators, including cabinet 100 and thermal insulating door thermally insulated door 200, further include above-mentioned
Hinge component 300 with auto-lock function, the sleeve of the hinge component 300 with auto-lock function are arranged on the cabinet 1
On, the first axle portion of the hinge component 300 with auto-lock function is connect with the thermal insulating door thermally insulated door 200.
Specifically, in actual use, if necessary to thermal insulating door thermally insulated door 200 is erect into setting and retainer state not
Become, then thermal insulating door thermally insulated door 200 is overturn into opening so that the first axle portion with the hinge component 300 of auto-lock function is inserted into sleeve
Middle to realize locking, the hinge component 300 with auto-lock function can provide reliable support force to thermal insulating door thermally insulated door 200, avoid the occurrence of
Thermal insulating door thermally insulated door 200 is overturn down due to external force.Mounting groove 101 is wherein provided in cabinet 100, the sleeve is embedded in the mounting groove
In 101, sleeve is embedded into mounting groove 101, it is ensured that has reliable between the hinge component 300 of auto-lock function and cabinet 100
Connection；And be provided on the thermal insulating door thermally insulated door 200 and strengthen iron 201, the first axle portion is connect with the reinforcement iron 201, is strengthened
Iron 201 can effectively enhance the bonding strength between thermal insulating door thermally insulated door 200 and the hinge component 300 with auto-lock function, improve door
The reliability of body.
Hinge component and refrigerator provided by the invention with auto-lock function install second hinge portion by using sleeve,
Second hinge portion in sleeve is slided, in actual use, when needing rotation, then lifts first axle
Portion, second hinge portion is to the outer Slideslip of sleeve so that shaft is located at the outside of sleeve, realizes that first axle portion can be relative to
Second hinge portion rotates, and when needing locking, then overturn the first articulated section and the second articulated section on the same line, and will turn
Axis is pressed into sleeve, and sleeve will limit first axle portion and be rotated relative to second hinge portion, and sleeve energy in the locked state
It is enough to provide the first articulated section stable support force without being influenced by access times, extend the hinge set with auto-lock function
The service life of part simultaneously improves the reliability used, to improve the reliability of refrigerator.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
