Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, and particularly relates to a locking mechanism and a refrigerator. Background Art

[0002] With the continuous improvement of living standards, refrigerators have become household appliances owned by most families, and people have higher and higher requirements for the use of refrigerators. A refrigerator separates the interior of the refrigeration device from the outside by the magnetic strip inside the door seal of the door body attracting the metal plate outside the box body.

[0003] However, due to the heat transfer of the magnetic strip of the door seal itself, the cold at the door seal attraction position is easily transferred to the outside through the magnetic strip, resulting in condensation at the door seal attraction position; at the same time, the magnitude of the magnetic force of the magnetic strip also determines the opening force of the refrigerator door. Excessive or too small opening force of the refrigerator door will also cause problems with condensation. If the closing force is too small, it is easy to have poor sealing and cold leakage and condensation; in addition, during long-term use, the magnetic strip will also deform, resulting in poor sealing of the ice door body, cold leakage and condensation.

[0004] Therefore, the existing technology needs to be further developed. Summary of the Utility Model

Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] See Figures 1 to 7, according to an embodiment of the present utility model, a locking mechanism is provided, including: a box body 1; a door body 2, the door body 2 is movably arranged to open or close the box body 1; a clamping structure 3, the clamping structure 3 is arranged on the box body 1 and the door body 2; the clamping structure 3 includes a tongue member 31 and a snap spring member 32 that are detachably connected to each other; when the tongue member 31 is connected to the snap spring member 32, the door body 2 closes the box body 1, and the clamping structure 3 fixes the relative positions of the door body 2 and the box body 1. With the above arrangement, the box body 1 and the door body 2 are fixed by the clamping structure 3, so there is no need to set a magnetic attraction or the like to fix the door body 2, and the connection will not fail due to the deformation of the magnetic strip, nor will heat transfer be caused by setting a magnetic strip or other structures, resulting in condensation, solving the technical problem of poor door suction of the refrigerator.

[0030] In the locking mechanism of this embodiment, refer to Figure 2 , a sealing strip 21 is arranged on the door body 2; when the door body 2 closes the box body 1, the sealing strip 21 fits with the box body 1 to make the door body 2 and the box body 1 be hermetically connected. By setting the form of combining the sealing strip 21 with the clamping structure 3, the sealing strip 21 can firmly seal the refrigerator.

[0031] Specifically, because of the existence of the clamping structure 3, the sealing strip 21 of this embodiment does not need to be provided with a magnetic attraction structure inside, thereby improving the service life of the sealing strip 21.

[0032] Refer to Figures 5 to 7 , in the locking mechanism of this embodiment, the tongue member 31 includes a protruding portion 311; the snap spring member 32 includes a slot 321 and a fixing portion 322 arranged in the slot 321; when the tongue member 31 is connected to the snap spring member 32, the protruding portion 311 is inserted into the slot 321, and the fixing portion 322 is connected to the protruding portion 311 to fix the position of the protruding portion 311. In this way, when the door body 2 is closed, the force of the rotation of the door body 2 causes the tongue member 31 to enter the inside of the slot 321 to complete the connection. The operation is convenient and labor-saving.

[0033] Refer to Figure 7 , in the locking mechanism of this embodiment, the slot 321 includes a receiving groove 3211 and a fixing groove 3212; one end of the fixing groove 3212 is communicated with the receiving groove 3211, and the other end of the fixing groove 3212 is communicated to the outside of the slot 321; the fixing portion 322 is arranged in the fixing groove 3212. In this way, the fixing portion 322 can be fixed from the root of the fixing portion 322, so that the connection of the structure is more firm.

[0034] In the locking mechanism of this embodiment, refer to Figure 2 , the tongue member 31 includes: a mounting portion 312, the mounting portion 312 is connected to the box body 1; the protruding portion 311 is connected to the mounting portion 312, and the protruding portion 311 protrudes from the mounting portion 312.

[0035] See Figure 2 Figure 2 , in the locking mechanism of this embodiment, the convex portion 311 includes: a first convex portion 3111, and the first convex portion 3111 is connected to the mounting portion 312; a second convex portion 3112, and the second convex portion 3112 is connected to one end of the first convex portion 3111 away from the mounting portion 312; along the direction in which the convex portion 311 is away from the mounting portion 312, the cross-sectional area of the second convex portion 3112 is larger than that of the first convex portion 3111. In this way, a greater force needs to be applied to disengage the second convex portion 3112 from the card slot member 31, and moreover, by setting the force for disengaging the second convex portion 3112 from the card slot member 31, the magnitude of the force for opening and closing the door body 2 can be set, which facilitates the production of the refrigerator.

[0036] In the locking mechanism of this embodiment, the fixing portion 322 includes a first fixing portion 3221 and a second fixing portion 3222 which are oppositely arranged; when the second convex portion 3112 is inserted into the receiving groove 3211, the first fixing portion 3221 and the second fixing portion 3222 clamp the first convex portion 3111 between the first fixing portion 3221 and the second fixing portion 3222. In this way, it can be ensured that when the clamping structure 3 is connected or disconnected, the force is evenly distributed, ensuring the structural stability.

[0037] In the locking mechanism of this embodiment, see Figures 5 to 7 Figures 5 to 7 , the outer surface of the second convex portion 3112 in contact with the fixing portion 322 is an arc surface; and / or, a buffer pad for abutting against the fixing portion 322 is provided on the first convex portion 3111.

[0038] Specifically, setting the outer surface of the second convex portion 3112 in contact with the fixing portion 322 to be an arc surface can ensure the smooth connection and disengagement of the clamping structure 3. A buffer pad for abutting against the fixing portion 322 is provided on the first convex portion 3111, which can reduce the collision between the tongue member 31 and the clip member 32.

[0039] See Figure 5 Figure 5 , in the locking mechanism of this embodiment, when the tongue member 31 is connected to the clip member 32, the inner wall surface of the receiving groove 3211 is spaced apart from the second convex portion 3112 to form a connection gap 33 between the inner wall surface of the receiving groove 3211 and the second convex portion 3112. In this way, when the second convex portion 3112 enters the receiving groove 3211, it will not contact other structures, thereby ensuring that the connection process will not be hindered and ensuring the service life of the structure.

[0040] The refrigerator of this embodiment includes a locking structure, and the locking structure is the above-mentioned locking structure.

[0041] In the locking mechanism of this embodiment, the locking mechanism includes a fastener 4, which is inserted on the tongue member 31 and the snap ring member 32 to connect the clamping structure 3 with the door body 2 and the box body 1; and / or, there are multiple clamping structures 3, and the multiple clamping structures 3 are arranged at intervals.

[0042] Specifically, referring to the attached Figure 1 For the locking mechanism and the refrigerator refrigeration equipment with this structure, the tongue member 31 is inlaid in the refrigerator box body 1 and fixed with screws (the fastener 4 in this embodiment). The snap ring member 32 is fixed at the corresponding position of the door body 2 with screws. The tongue member 31 and the snap ring member 32 are used in pairs. The number of the tongue member 31 and the snap ring member 32 is determined according to the overall size of the refrigerator. In this case, four are used, as Figure 2 , and the specific implementation cases are as follows:

[0043] The opening force of the traditional ice door body 2 depends on the magnetic force of the magnetic strip in the door seal. If the magnetic force is large, the opening force is too large, which affects the user experience and is likely to cause user complaints. If the magnetic force is small, the opening force is small, but it is easy to cause cold leakage, resulting in condensation of the door seal and is also likely to cause user complaints. In the present utility model, through the cooperation of the clamping structure, by calculating the elastic force of the snap ring member 32 and the interference amount between the tongue member 31 and the snap ring member 32, the door opening force is controlled, the opening force is quantified, and the opening force is controlled within a specified range, improving the product consistency and enhancing the user experience.

[0044] The cooperation of the tongue member 31 and the snap ring member 32 is used to lock the ice door body 2 and the box body 1, replacing the traditional mode: the door body 2 and the box body 1 are separated from the outside by the attraction of the magnetic strip inside the door seal and the metal plate outside the box body 1. The magnetic strip transfers the cold through heat conduction, resulting in condensation of the door seal, solving the industry pain point of condensation of the door seal. The sealing strip of this locking method only has a sealing function and no magnetic strip, and the heat conduction between the inside and outside of the refrigerator is much lower than the traditional sealing form.

[0045] The traditional door seal rubber sleeve is prone to deformation and elongation during use, resulting in deformation and sagging of the magnetic strip, and the door cannot be closed normally, causing cold leakage and condensation, resulting in user complaints. After the rubber sleeve and the magnetic strip are deformed, the entire door seal must be replaced. The after-sales complaint rate and the after-sales scrap rate are both very high. However, the present utility model describes a method of locking the ice door body 2 and the box body 1 through the cooperation of the tongue member 31 and the snap ring member 32. The tongue member 31 and the snap ring member 32 are flexibly matched, with strong controllability, convenient locking, fixed opening force, easy to open the ice door body 2, and only one pair of parts needs to be changed in case of failure, simple disassembly, and low scrap rate.
