An embodiment of the present utility model provides a booster 10. The booster 10 is used to mount a press inverter box assembly 21 of a refrigerator 20. The booster 10 includes a fixed plate 11 and a link mechanism 12. Wherein the linkage 12 includes a first lever portion 121, a second lever portion 122, and a rotation mechanism 123. The rotation mechanism 123 is disposed on the fixed plate 11, and the first lever portion 121 and the second lever portion 122 are rotatably connected to the fixed plate 11 through the rotation mechanism 123.

According to the mechanism, when the link mechanism 12 is connected with the fixing plate 11, the first lever portion 121 is rotated, so that the second lever portion 122 rotates under the action of the rotating mechanism 123, and when the second lever portion 122 is attached to the press variable frequency box assembly 21, the second lever portion 122 can promote the assembly between the press variable frequency box assemblies 21, so that the assembly of the press variable frequency box assembly 21 is simpler and more labor-saving, and the working efficiency of production personnel in the production and assembly process can be improved.

Further, the length of the first lever portion 121 is greater than the length of the second lever portion 122. At this time, according to the lever principle, the force applied by the producer is smaller as the distance from the rotating mechanism 123 is longer when the producer holds the first lever portion 121. And the shorter the distance of the press inverter box assembly 21 from the rotating mechanism 123, the smaller the force applied by the producer. Therefore, when the length of the first lever portion 121 is greater than the length of the second lever portion 122, a smaller force can be applied to effect the rotation of the first lever portion 121 when a manufacturer performs an assembly work. In the working process, the labor is saved, and the working efficiency of production personnel in the production and assembly process can be improved.

In an embodiment of the present utility model, the rotation mechanism 123 includes a first rotation shaft 1232 and a fixing member 1231. The fixing member 1231 is disposed on the fixing plate 11, and a first through hole (not shown in the drawing) is formed in the fixing member 1231, and the first rotating shaft 1232 is disposed through the first through hole. The first rotation shaft 1232 is provided to enable a rotational connection between the first lever part 121 and the second lever part 122. The fixing member 1231 is disposed such that the first lever portion 121 and the second lever portion 122 rotate about a certain point of the fixing plate 11. And the provision of the fixing member 1231 also makes the connection between the rotation mechanism 123 and the fixing plate 11 more stable. Further, the connection between the link mechanism 12 and the fixed plate 11 is more stable. The booster 10 can be more stable during the completion of the assembly work.

In an embodiment of the present utility model, the linkage 12 further includes an abutment 124 and a second rotational shaft 125. The second rotating shaft 125 is disposed at an end of the second lever portion 122 facing away from the first rotating shaft 1232, and the abutting portion 124 is rotatably connected to the second lever portion 122 through the second rotating shaft 125. Therefore, during the operation of the booster 10, the second lever portion 122 is better adapted to the movement state of the press inverter box assembly 21, and the abutment portion 124 needs to be always attached to the press inverter box assembly 21. The second lever portion 122 is rotated by the second rotating shaft 125, so that the second lever portion 122 always keeps a fit state with the press variable frequency box assembly 21 in a moving process, and the overall adaptability of the booster device 10 is stronger.

Further, the abutment 124 includes an abutment plate 1241, a first connection plate 1242 and a second connection plate 1243. Wherein, the first connecting plate 1242 and the second connecting plate 1243 are fixed on or integrally formed with the abutting plate 1241, the first connecting plate 1242 is provided with a second through hole 1244, the second connecting plate 1243 is provided with a third through hole 1245, and the second rotating shaft 125 is arranged through the second through hole 1244 and the third through hole 1245. The arrangement of the abutting plate 1241 can increase the stress area between the abutting portion 124 and the press variable frequency box assembly 21, so that the phenomenon that the press variable frequency box assembly 21 is pressed due to overlarge pressure between the abutting portion 124 and the press variable frequency box assembly 21 and the attractiveness of the press variable frequency box assembly is influenced is avoided. The first connecting plate 1242 and the second connecting plate 1243 are respectively provided with a second through hole 1244 and a third through hole 1245, and the second rotating shaft 125 is arranged through the second through hole 1244 and the third through hole 1245, so that the rotating connection between the second rotating shaft 125 and the second lever portion 122 is smoother.

It should be noted that, in the embodiment of the present utility model, the first connecting plate 1242 and the second connecting plate 1245 are fixedly connected to the abutment plate 1241 through an integral molding. The first and second connection plates 1242, 1243 may also be welded to form a fixed connection with the abutment plate 1241. In other embodiments, the first connecting plate 1242 and the second connecting plate 1243 may be fixedly connected by a hinge, which is not limited herein.

The first fixing plate 111 is fixed to or integrally formed with the second fixing plate 112. The fixing member 1231 is fixed to or integrally formed with the second fixing plate 112. When the fixing member 1231 is fixed on the second fixing plate 112, the first fixing plate 111 can perform a certain limiting function on the link mechanism 12. During the assembly of the press conversion box assembly 21, the first link 1211 stops rotating when the first link 1211 abuts against the first fixing plate 111. Therefore, the fixing member 1231 is fixed to the second fixing plate 112, so that the problem of assembly failure caused by excessive rotation of the first link 1211 can be effectively avoided. It should be noted that, the first fixing plate 111 and the second fixing plate 112 may be further connected by welding, and the first fixing plate 111 and the second fixing plate 112 may be further connected by integrally forming. In other embodiments, the connection between the first fixing plate 111 and the second fixing plate 112 may be achieved by means of a hinge, which is not limited herein. The fixing member 1231 may be fixed to the first fixing plate 111 by welding, and the fixing member 1231 may be fixed to the first fixing plate 111 by integral molding, which is not limited herein.

Further, a certain angle is formed between the first fixing plate 111 and the second fixing plate 112. At this time, the first fixing plate 111 and the second fixing plate 112 can be more stably attached to the case 15 of the refrigerator 20. Optimally, the angle between the first fixing plate 111 and the second fixing plate 112 is 90 °. When the booster 10 is suitable for assembling other objects, the angle between the first fixing plate 111 and the second fixing plate 112 may be other angles, which is determined according to the application scenario of the booster 10, and is not limited herein.

In an embodiment of the present utility model, the first lever portion 121 includes a first link 1211 and a handle member 126. Wherein the first link 1211 is rotatably coupled to the first fixing plate 111 through a first rotation shaft 1232.

At this time, when the assembly of the press conversion box assembly 21 is performed, the manufacturer can grasp the handle member 126 to achieve rapid assembly. It should be noted that, in the embodiment of the present utility model, the first link 1211 includes a first sub-link 1212 and a second sub-link 1213 that are parallel to each other. On the one hand, the arrangement of the first sub link 1212 and the second sub link 1213 can make the connection between the first link 1211 and the first rotation shaft 1232 more stable; on the other hand, the first sub-link 1212 and the second sub-link 1213 are capable of transmitting the force applied by the producer to the second lever portion 122 to a greater extent, thereby making the whole assembly process more labor-saving. Of course, in other embodiments, only one first sub-link 1212 may be provided for the first link 1211, and a quick assembly process may be implemented at this time, which is not described herein.

It should be noted that, in the embodiment of the present utility model, the second link 1221 includes a third sub-link 1222 and a fourth sub-link 1225 that are parallel to each other. On the one hand, the arrangement of the third sub-link 1222 and the fourth sub-link 1225 can make the connection between the second link 1221 and the second rotation shaft 125 and the first rotation shaft 1232 more stable; on the other hand, the third and fourth sub-links 1222, 1225 can provide greater force on the press conversion box assembly 21, and thus, the overall assembly process can be more labor efficient. Of course, in other embodiments, only one third sub-link 1222 may be provided for the second link 1221, and a quick assembly process may be implemented, which is not described herein.

Further, a fourth through hole 1223 is formed at the connection position between the first connecting rod 1211 and the second connecting rod 1221 corresponding to the first through hole, and the first rotating shaft 1232 is disposed through the first through hole and the fourth through hole 1223. At this time, the rotational connection between the first rotating shaft 1232 and the first lever portion 121 and the second lever portion 122 is more stable and smoother, and the pressure action of the second lever portion 122 on the press inverter box 21 can be easily achieved by rotating the first lever portion 121 during the process of operating the booster 10. Therefore, the whole device can save more labor in the assembly process, and the whole work efficiency of production staff can be effectively improved.

Further, the handle member 126 is provided with a first opening 1261, and when a manufacturer operates the first lever portion 121 to perform assembly, the manufacturer can rotate the first lever portion 121 by holding the first opening 1261. The arrangement of the first opening 1261 also makes the operation process of the production staff more labor-saving, and further can improve the working efficiency of the staff.

Specifically, the producer starts to rotate the first lever portion 121 by holding the first opening 1261 of the handle member 126, and the second lever portion 122 starts to rotate under the action of the first rotating shaft 1232, thereby pushing the inverter box 14 to be assembled on the compressor 13. The abutting plate 1241 of the second lever portion 122 always keeps the abutting state with the inverter box 14, so when the second lever portion 122 pushes the inverter box 14 to be assembled on the compressor 13, the second rotating shaft 125 also continuously rotates at a position adapting to the inverter box 14, so that the abutting plate always keeps the abutting state with the inverter box 14. In the assembly process, the through holes on the compressor 13 and the variable frequency box 14 are continuously attached until the positions of the through holes on the compressor 13 and the variable frequency box 14 are mutually overlapped, which indicates that the assembly between the compressor 13 and the variable frequency box 14 is completed.
