Figure 1 As shown, the cabinet door lock rod structure includes a driving mechanism 210, an upper connecting rod assembly 220, and a lower connecting rod assembly 230. The driving mechanism 210 is close to the opening and closing side 102 of the cabinet door 100 and is located in the middle position. The driving mechanism 210 is connected to the inner side 103 of the cabinet door 100. The upper connecting rod assembly 220 is located on the inner side of the cabinet door 100 and is located above the driving mechanism 210. The length direction of the upper connecting rod assembly 220 is the same as the height direction of the cabinet door 100. One end of the upper connecting rod assembly 220 in the length direction is connected to the driving mechanism 210, and the other end is close to the top of the cabinet door 100. The lower connecting rod assembly 230 is connected to the cabinet door 100.

The first connecting rod 221 and the second connecting rod 222 are against each other in the thickness direction and overlapped together. The two side surfaces in the thickness direction of the first connecting rod 221 and the second connecting rod 222 are perpendicular to the inner side surface 103 of the cabinet door 100. In order to further increase the strength of the locking rod structure, the first connecting rod 221 and the second connecting rod 222 can be welded and fixed.

[0026] In other embodiments, the side surfaces of the first connecting rod 221 and the second connecting rod 222 in the thickness direction may also be parallel to the inner side surface 103 of the cabinet door, and may also be connected and fixed by bolts.

[0027] Specifically, the upper connecting rod assembly 220 further includes a fixing member 240, and the fixing member 240 includes a fixing portion and a positioning portion, the fixing portion is connected to the inner side surface 103 of the cabinet door 100, and the positioning portion is buckled and connected to the first connecting rod 221 and the second connecting rod 222 to limit the movement of the first connecting rod 221 and the second connecting rod 222 in the width direction and the thickness direction of the cabinet door 100. The lower connecting rod assembly 230 is the same as the upper connecting rod assembly 220, and also includes the fixing member 240, and the number of the fixing members 240 is the same, and the connection method with the fixing members 240 is also the same.

Taking the example of the connecting rod assembly 220 including four fixing members 240, the first connecting rod 221 and the second connecting rod 222 are inserted into the fixing groove 242, so that the fixing member 240 is buckled on the first connecting rod 221 and the second connecting rod 222, and the notch of the fixing groove 242 faces the inner side 103 of the cabinet door 100, so that the first connecting rod 221 and the second connecting rod 222 can only move along the height direction of the cabinet door 100, and the movement outside the height direction is limited. In this embodiment, the fixing member 240 is made of metal material in one piece, has high strength, is not easily deformed, and better limits the degree of deformation of the lock rod. The fixing groove 242 also plays a guiding role, so that the first connecting rod 221 and the second connecting rod 222 move smoothly. In addition, when the fixing member 240 needs to be replaced, it is sufficient to remove the bolts on the fixing hole 242 without removing the entire lock rod, which is convenient for maintenance.

[0029] The cabinet door lock rod structure also includes an upper limit assembly 250 and a lower limit assembly 260. The upper limit assembly 250 is connected to an end of the upper connecting rod assembly 220 that is away from the driving mechanism 210 in the length direction. The upper limit assembly 250 moves up and down synchronously with the upper connecting rod assembly 220. When moving up, the upper limit assembly 250 is engaged with the cabinet body, so that the cabinet door 100 and the cabinet body are connected at the top position. When moving down, the upper limit assembly 250 is separated from the cabinet body so that the cabinet door 100 can be opened; the lower limit assembly 260 is away from the lower connecting rod assembly 230 in the length direction. One end of the driving mechanism 210 is connected, and the lower limit assembly 260 moves up and down synchronously with the lower connecting rod assembly 230. When moving downward, the lower limit assembly 260 is engaged with the cabinet body, so that the cabinet door 100 and the cabinet body are connected at the bottom position. When moving upward, the lower limit assembly 260 is separated from the cabinet body so that the cabinet door 100 can be opened; the upper limit assembly 250 and the lower limit assembly 260 are used to realize the closure of the cabinet door and the cabinet body, and the sealing is enhanced, and the cabinet body is provided with parts engaged with the upper limit assembly and the lower limit assembly at corresponding positions on the top and bottom.

[0030] Specifically, the upper limit assembly 250 includes an adjustment plate 251, a limit plate 252 and a roller 253. One side of the adjustment plate 251 is connected to the upper connecting rod assembly 220, and the other side is connected to the limit plate 252. The limit plate 252 is connected to the roller 253. The roller 253 is used to engage with the cabinet. The adjustment plate 251 is used to adjust the distance between the roller 253 and the cabinet door 100 so as to engage with cabinets with different size tolerances. Figure 4 As shown, the adjustment plate 251 is provided with multiple groups of first mounting holes 254, each group has at least two first mounting holes 254, the first mounting holes 254 in each group are arranged at intervals along the height direction of the cabinet door 100, and the multiple groups of first mounting holes 254 are arranged at intervals along the width direction of the cabinet door 100; the limiting plate 252 is provided with at least two second mounting holes 255, and the first mounting holes 254 and the second mounting holes 255 are bolted. When the cabinet door 100 and the cabinet body are produced, there will be manufacturing tolerances. If the tolerance is too large, the upper limit assembly 250 cannot be smoothly connected with the cabinet body, affecting the closing of the cabinet door. By setting multiple groups of first mounting holes 254 on the adjustment plate 251, when the tolerance is too large, another group of first mounting holes 254 can be replaced to connect with the second mounting holes 255, so as to adjust the distance between the roller 253 and the cabinet door 100, and solve the problem that the tolerance is too large and cannot be smoothly connected with the cabinet body. One side of the limit plate 252 is connected to the adjustment plate 251, and the other side extends upward to form a limit rod, the top of the limit rod is connected to the roller 253, and the upper limit assembly 250 extends into the cabinet through the limit rod and the roller 253 and is engaged with the cabinet.

[0031] Specifically, it also includes at least two limit pads 270, and the at least two limit pads 270 are respectively located between the inner side surface 103 of the cabinet door 100 and the upper connecting rod assembly 220, and between the inner side surface 103 of the cabinet door 100 and the lower connecting rod assembly 230, and are respectively close to the upper limit assembly 250 and the lower limit assembly 260. One side of at least two limit pads 270 is connected to the inner side surface 103 of the cabinet door 100, which can be welded, and the other side is respectively abutted against the upper connecting rod assembly 220 or the lower connecting rod assembly 230, thereby further limiting the movement of the upper connecting rod assembly 220 and the lower connecting rod assembly 230 toward the cabinet door and increasing the strength of the cabinet door.

[0032] In this embodiment, the lock rod structure further includes a handle assembly 280, which is connected to the outer side of the cabinet door 100. The handle assembly 280 is rotatably connected to the drive mechanism 210. When the handle assembly 280 rotates, the drive mechanism 210 rotates synchronously, thereby driving the upper connecting rod assembly 220 and the lower connecting rod assembly 230 to move up and down relative to each other. Figure 5 As shown, the driving mechanism 210 includes a transmission gear 211, a first driving member 212 and a second driving member 213. One end of the first driving member 212 is provided with a first connecting hole 2122, and the first connecting hole 2122 is connected to the upper connecting rod assembly 220.
