Detailed implementation manners

[0025] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0026] Embodiment 1

[0027] As Figures 1 to 2As shown in the figure, a refrigerator drawer seal includes a seal body 1, and a deformable sealing cylinder 2 is connected to the lower end of the seal body 1; the sealing cylinder 2 includes an inner surface 202 and an outer surface 201 for movably connecting with the drawer 3. The inner surface 202 forms a compressible space. Since the drawer 3 itself does not have airtightness, the moisture in it is likely to be carried away by the cooling air, which accelerates the water evaporation of the fruits and vegetables placed in it, causing them to dry out and lose water, shortening the fresh-keeping period, and being unfavorable for the moisture preservation of fruits and vegetables. Therefore, the specific function of this utility model is that when the drawer 3 is pushed closer to the sealing cylinder 2 and pressed against the outer surface 201, the compressible space will be compressed, and at the same time, the outer surface 201 will deform and closely adhere to the edge of the drawer 3 to form a seal for the drawer 3, so as to prevent water from leaking through the gap, effectively ensuring the sealing effect of the drawer 3. And the sealing cylinder 2 has a certain elastic function. By buffering the interval between the cover plate 4 and the drawer 3 through the sealing cylinder 2, the noise generated by collision can be effectively avoided.

[0028] Specifically, as Figures 1 to 3 shown, the seal body 1 includes an installation kit for connecting and fixing on the cover plate 4. The installation kit is a semi-enclosed structure that wraps around the front end of the cover plate 4; the installation kit includes a connecting plate 104. One end of the connecting plate 104 is connected to a first clamping plate 101, and the other end of the connecting plate 104 is connected to a second clamping plate 102. A clamping space 103 for inserting the cover plate 4 is formed between the first clamping plate 101 and the second clamping plate 102. The cover plate 4 is clamped and fixed by the cooperation of the first clamping plate 101 and the second clamping plate 102.

[0029] As Figure 2 shown, the connecting plate 104 is inclined from top to bottom, and the inclination direction is convenient for the user to wipe and clean; fillets 109 are formed at the joints of the connecting plate 104 and the first clamping plate 101 and at the joints of the connecting plate 104 and the second clamping plate 102. The fillet 109 design can effectively avoid wear of the seal body 1 and extend the service life of the seal body 1.

[0030] At least one convex strip 1021 extends along the length of the upper surface of the second clamping plate 102; the convex strip 1021 is located below the first clamping plate 101; the width of the convex strip 1021 is 1.5 to 4.5 mm, and the height of the convex strip 1021 is 1.5 to 4.5 mm. In this embodiment, the width of the convex strip 1021 is 2 mm, and the height of the convex strip 1021 is 2 mm, that is, the cross-section of the convex strip 1021 is square. Such a size can meet the requirement of increasing the friction force without affecting the pushing and installation of the cover plate 4; the convex strip 1021 design can make the side of the cover plate 4 adhere to the first clamping plate 101 and increase the friction force, thereby preventing the cover plate 3 from loosening from the clamping space 103.

[0031] A baffle 105 is connected below the second clamping plate 102. The upper end of the baffle 105 is perpendicular to the end of the second clamping plate 102, and the lower end of the baffle 105 is fixedly connected to the sealing cylinder body 2. The baffle 105 can provide a certain supporting force for the sealing cylinder body 2.

[0032] Embodiment 2

[0033] As Figures 4 to 5 shown, this embodiment is an improvement based on Embodiment 1. The improvement of this embodiment lies in that: a support member 106 is connected below the second clamping plate 102. A support space is formed by an opening on the side of the support member 106. A plurality of reinforcing strips 1061 are distributed on both sides of the support space. The reinforcing strips 1061 can enhance the strength and rigidity of the support member 106 and enhance the support effect of the support member 106.

[0034] The support member 106 is connected with a support plate 107. The end of the support plate 107 is upturned upward to form an arc position 108. The sealing cylinder body 2 is arranged on the arc position 108. The design of the arc position 108 can be more fitted with the sealing cylinder body 2 and provide a better support effect for the sealing cylinder body 2.

[0035] The first clamping plate 101 extends outward to form an arc end 1011, and the second clamping plate 102 extends outward to form a guiding end 1022. An insertion port is formed by clamping between the arc end 1011 and the guiding end 1022. The insertion port is communicated with the clamping space 103. During assembly, the cover plate 4 is inserted into the clamping space 103 from the insertion port, so as to realize the fixed connection between the sealing member body 1 and the cover plate 4.

[0036] The upper surface of the guiding end 1022 is inclined upward from bottom to top to form a guiding position 1023. The guiding position 1023 corresponds to the arc end 1011. The arc end 1011 can effectively prevent the surface of the cover plate 4 from being worn when the cover plate 4 is assembled; the guiding position 1023 plays a guiding role to facilitate the insertion of the cover plate 4.

[0037] Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
