Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] Reference Figures 1 to 3 , is a sealing strip for a constant temperature display cabinet disclosed in the utility model, comprising a cabinet door 1, a card slot 2 is opened inside the cabinet door 1, an iron plate is arranged at the bottom of the card slot 2, a sealing strip 4 is arranged inside the card slot 2, the sealing strip 4 comprises a clamping block 5, a magnetic block 6 is arranged inside the clamping block 5, a buffer tendon 7 is arranged on the top of the clamping block 5, a buffer cavity 8 is arranged on one side of the buffer tendon 7, a heat preservation cavity 9 is arranged on the side of the buffer tendon 7 away from the buffer cavity 8, an air inlet 10 is arranged on the top of the heat preservation cavity 9, an air outlet 13 is arranged at the bottom of the heat preservation cavity 9, and a heat insulation cavity 11 is arranged at the bottom of the heat preservation cavity 9.

[0028] Grooves 12 are provided on both sides of the sealing strip 4. The heat conduction at the sealing strip 4 can be blocked by the insulation cavity 9 and the buffer cavity 8, thereby blocking external heat and improving the air barrier effect. Moreover, through the cooperation of the buffer cavity 8 and the buffer tendon 7, a certain shock-absorbing effect can be achieved.

[0029] The clamping block 5 is clamped in the inside of the clamping slot 2. Through the cooperation between the clamping block 5 and the clamping slot 2, the sealing strip 4 can be conveniently installed, the installation time can be reduced, and the installation efficiency can be improved.

[0030] The contact area between the top of the buffer tendon 7 and the sealing strip 4 is larger than the contact area between the buffer tendon 7 and the sealing strip 4. By setting the buffer tendon 7, the insulation cavity 9 and the buffer cavity 8 can be supported and rebounded to avoid long-term extrusion that causes the insulation cavity 9 to collapse, thereby improving the deformation resistance of the sealing strip 4 and extending the service life of the sealing strip 4.

[0031] The magnetic block 6 is fixedly connected to the clamping block 5 . By providing the magnetic block 6 , the connection between the clamping block 5 and the clamping slot 2 can be increased, thereby improving the connection effect between the sealing strip 4 and the cabinet door 1 .

[0032] The sealing strip 4 is made of rubber material. By adopting rubber material, the rubber material has good elasticity and deformation ability, can effectively fill and seal the gap between the refrigerator and the outside world, prevent air circulation, and improve the sealing performance of the cabinet.

[0033] The implementation principle of this embodiment is:

[0034] When installing the sealing strip 4, since the sealing strip 4 is made of rubber and is relatively soft, the card block 5 can be squeezed into the card slot 2, so that the magnetic block 6 is connected to the iron block 3 to complete the installation. The general sealing strip 4 is exposed to cold air for a long time and the alternation of hot and cold air leads to accelerated aging. In this embodiment, an air inlet 10 is opened inside the insulation cavity 9. When the cabinet door 1 is opened and closed, normal temperature air enters the insulation cavity 9, and the temperature of the sealing strip 4 is increased from the inside, reducing the aging rate. In addition, there is an insulating cavity 11 on one side of the insulation cavity 9. The double cavity can reduce the propagation speed of cold air, better isolate the flow of cold air, and further increase the service life of the sealing strip 4. Therefore, the device has certain practicality.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] The sealing strip 4 for the constant temperature display cabinet can block the heat conduction at the sealing strip 4 through the heat preservation cavity 9 and the buffer cavity 8, thereby blocking external heat and improving the air blocking effect. By setting the air inlet 10, when the staff opens and closes the cabinet door 1, normal temperature air can enter the heat preservation cavity 9 through the air inlet 10, and then enter the heat insulation cavity 11 through the air outlet 13, so that the heat preservation cavity 9 and the heat insulation cavity 11 separate the buffer cavity 8 from the interior of the cabinet, thereby reducing the aging speed of the sealing strip 4, and through the cooperation of the buffer cavity 8 and the buffer tendon 7, it can have a certain shock absorption effect and reduce the generation of noise. By setting the magnetic suction block 6, the connection between the card block 5 and the card slot 2 can be increased, and the connection effect between the sealing strip and the cabinet door 1 can be improved.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
