Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerator component installation, in particular to a refrigerator door sealing strip installation device. Background Art

[0002] The refrigerator door sealing strip is a strip made of rubber or silicone, fixed on the refrigerator door to seal the gap between the door and the refrigerator body. Its main function is to maintain stable temperature and humidity in the refrigerator, prevent cold air from leaking out and hot air from entering, so that food can stay fresh. The existing refrigerator door sealing strip will apply glue to the groove of the refrigerator door during installation, so that the sealing strip can be smoothly fastened and installed on the refrigerator door later. When the operator holds the glue gun and glues the groove, it is impossible to accurately follow the straight line of the groove, resulting in an uneven glue route. As a result, the glue cannot be evenly contacted with the sealing strip when it is installed and fitted, which greatly reduces the fastening effect. Therefore, it needs to be improved.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a refrigerator door sealing strip installation device, including a gluing device body 1, a mounting plate 2 is movably installed on the front end of the surface of the gluing device body 1, and a limit clamping plate 3 is movably installed on the front and rear sides of the back of the mounting plate 2. A limit rod 5 located on the inner side of the front end of the limit clamping plate 3 is fixedly installed on the inner wall of the mounting plate 2, a linkage slider 6 is movably sleeved on the surface of the limit rod 5, and a first spring 7 located on the surface of the limit rod 5 is fixedly installed on the inner end of the linkage slider 6, and a driven rack 8 is fixedly installed above and below the bottom end of the linkage slider 6 respectively, and a driving gear 9 is movably installed on the inner wall of the mounting plate 2 at the inner end of the inner side of the driven rack 8.

[0021] Through the meshing relationship between the inner surface of the driven rack 8 and the outer surface of the driving gear 9, when the rotating drive rod 10 drives the driving gear 9 to rotate, the two driven racks 8 can be driven towards each other, and then the two linked sliders 6 and the limit clamping plate 3 are synchronously pulled to move towards each other, so that the rear end of the limit clamping plate 3 can be subsequently inserted into the refrigerator door groove for clamping and limiting.

[0022] like Figure 4 As shown, the other end of the first spring 7 is fixedly connected to the inner wall of the mounting plate 2 , and the inner wall of the first spring 7 is movably connected to the surface of the limiting rod 5 .

[0023] By adopting the above solution and providing the limit rod 5 , when the first spring 7 pushes the linkage slider 6 and the limit clamping plate 3 to move away from each other, they will smoothly slide away from each other in the horizontal direction under the limiting action of the limit rod 5 .

[0024] like Figure 2 As shown, a rotation driving rod 10 located in front of the driving gear 9 is movably sleeved on the inner wall of the mounting plate 2 , and a rear end of the rotation driving rod 10 is fixedly connected to the inner wall of the driving gear 9 .

[0025] By adopting the above solution, by providing the rotating driving rod 10 , when the operator rotates the rotating driving rod 10 , the driving gear 9 can be smoothly driven to rotate on the inner wall of the mounting plate 2 .

[0026] like Figure 5 As shown, the inner surface of the driven rack 8 is meshed with the outer surface of the driving gear 9, and the number of the driven racks 8 is two.

[0027] By adopting the above scheme, a driven rack 8 is provided. When the rotating drive rod 10 drives the driving gear 9 to rotate, the two driven racks 8, the linkage slider 6 and the limit clamping plate 3 can be driven to move towards each other as a whole, so that the rear end part of the limit clamping plate 3 can be inserted into the refrigerator door groove later.

[0028] like Figure 3 As shown, the front and rear sides of the inner end of the mounting plate 2 are both fixedly mounted on the annular limiting blocks 15 on the inner wall of the gluing device body 1 .

[0029] By adopting the above solution, the circular limiting block 15 is designed so that the installation disk 2 can be movably sleeved on the front end surface of the glue application device body 1, and the subsequent rotation of the installation disk 2 can be limited at the same time.

[0030] like Figure 5 As shown, the surface of the gluing device body 1 is provided with a fixed tooth block 11 located on the inner side of the mounting plate 2, and the inner wall of the mounting plate 2 is movably provided with a locking tooth plate 12 located in the middle of the top end of the fixed tooth block 11, and the bottom end of the locking tooth plate 12 is meshed with the surface of the fixed tooth block 11.

[0031] By adopting the above scheme, by providing a fixed tooth block 11 and a locking tooth plate 12, when the locking tooth plate 12 moves upward as a whole, the bottom end part of the locking tooth plate 12 can be separated from the top end part of the fixed tooth block 11, thereby releasing the fixing effect of the locking tooth plate 12 and the mounting disk 2 as a whole, and then the mounting disk 2 as a whole can be rotated smoothly.

[0032] like Figure 3 As shown, a second spring 13 is fixedly installed on the top of the locking tooth plate 12, and the other end of the second spring 13 is fixedly connected to the inner wall of the mounting plate 2. A movable pressing plate 14 is fixedly installed on the top of the front side of the second spring 13, and the front end of the movable pressing plate 14 extends to the front side of the mounting plate 2.

[0033] By adopting the above scheme, a second spring 13 is provided. When the movable pressing plate 14 is pushed to drive the locking tooth plate 12 upward, the second spring 13 will be squeezed. Then, when the movable pressing plate 14 is released, the elastic force of the second spring 13 can be released, thereby pushing the locking tooth plate 12 as a whole downward to engage and fix with the top of the fixed tooth block 11.

[0034] The working principle and use process of this utility model:

[0035] First, the operator can rotate the rotary drive rod 10 to drive the active gear 9 to rotate, thereby driving the two driven racks 8, the linkage slider 6 and the limit clamping plate 3 to move towards each other. Then the operator can insert the rear end part of the limit clamping plate 3 into the corresponding refrigerator door groove. Then the rotary drive rod 10 can be released, and the elastic force of the first spring 7 can be smoothly released to push the two linkage sliders 6 and the limit clamping plate 3 to move away from each other until the limit pulley 4 at the rear end of the limit clamping plate 3 fits with the inner wall of the groove. Finally, the operator can use the glue applying device body 1 and slide along the groove to apply glue.

[0036] Then, when the channel turns, the operator can push the movable pressing plate 14 to drive the locking tooth plate 12 to move upward, so that the bottom end of the locking tooth plate 12 is separated from the surface of the fixed tooth block 11 to release the meshing fixation, and then the gluing device body 1 can be smoothly rotated to a suitable angle as a whole, and then the movable pressing plate 14 is released, so that the elastic force of the second spring 13 pushes the locking tooth plate 12 downward to engage with the fixed tooth block 11 and fix the mounting plate 2 as a whole, which is convenient for the subsequent adaptive turning sliding gluing.
