Detailed Description

The invention is described in further detail below with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, the refrigerator liner supporting mechanism with the adjustable bridge plate chain comprises a six-column frame supporting mechanism 13 and a cabinet opening table 111. The six-column frame body supporting mechanism 13 is used for placing the processed refrigerator liner. When the refrigerator liner is placed on the six-column frame body supporting mechanism 13, the refrigerator liner is reversely buckled on the six-column frame body supporting mechanism in a mode that the opening of the refrigerator is downward. The cabinet opening table 111 is a horizontal table surface arranged on the six-column frame body supporting mechanism 13, and is adjustable in height and used for supporting the cabinet opening of the refrigerator liner when the refrigerator liner is reversely buckled on the six-column frame body supporting mechanism 13. The six-column frame body supporting mechanism 13 includes six columns. The frame structure size that six stands are constituteed is adjustable to match the freezer inner bag of equidimension not. The heights of the six stand columns are not adjustable, and the height of the cabinet opening table 111 is adjustable, so that the refrigerator liner supporting mechanism can support refrigerator liners with different heights.

The six columns of the six-column frame body supporting mechanism 13 are divided into three sets of column groups, and each set of column groups comprises two columns with the same height. The three sets of upright post groups are respectively: the first upright post group, the second upright post group and the third upright post group. The first column set and the second column set are tall columns 1331. The third set of posts is shorter than the first and second sets of posts, being short posts 1332. That is, the six posts of the six-post frame support mechanism 13 include four tall posts 1331 and two short posts 1332. The first upright post group, the second upright post group and the third upright post group are sequentially arranged and are positioned on the longitudinal central axis. The two stand columns of the three stand column groups are respectively arranged on two sides of the longitudinal central axis and are symmetrical with the longitudinal central axis, the spacing between the two stand columns of the three stand column groups is the same, and a step-shaped structure is formed at the tops of the six stand columns, so that the Z-shaped base plate can be matched.

The two tall posts 1331 of the first post set are vertically disposed on the first longitudinal translation plate 1313 by a lateral adjustment mechanism. Two tall posts 1331 of the second post set are vertically disposed on the longitudinal fixation plate 1317 by a lateral adjustment mechanism. Two short posts 1332 of the third post set are vertically disposed on second longitudinal translation plate 1316 by a lateral adjustment mechanism. The first longitudinal translation plate 1313 and the second longitudinal translation plate 1316 are horizontally mounted on a longitudinal slide rail 1311 parallel to the longitudinal central axis by a slider, and are respectively connected with a longitudinal translation driving mechanism: a first longitudinal translation drive mechanism and a second longitudinal translation drive mechanism. The longitudinal rails 1311 are horizontally mounted on the bottom plate 1300. The bottom plate 1300 is horizontally fixed to the base 110.

The first and second longitudinal translation driving mechanisms are respectively used for driving the first and second

longitudinal translation plates

1313 and 1316 to move along the longitudinal central axis. The first longitudinal translation drive mechanism includes a first longitudinal drive motor 1310 and a first longitudinal screw 1312. The first longitudinal screw 1312 is located on the longitudinal centerline and is connected to a first longitudinal drive motor 1310. The first longitudinal screw 1312 is connected to a first longitudinal translation plate 1313 by a wire sleeve. Thus, the first longitudinal driving motor 1310 drives the first longitudinal screw 1312 to rotate, and the first longitudinal translation plate 1313 is driven to translate on the longitudinal slide 1311 by the threaded engagement between the first longitudinal screw 1312 and the wire sleeve at the bottom of the first longitudinal translation plate 1313. The second longitudinal translation drive mechanism includes a second longitudinal drive motor 1314 and a second longitudinal lead screw 1315. A second longitudinal screw 1315 is located on the longitudinal centerline and is connected to a second longitudinal drive motor 1314. The second longitudinal screw 1315 is connected to a second longitudinal translation plate 1316 by a wire sleeve. Thus, the second longitudinal driving motor 1314 drives the second longitudinal screw 1315 to rotate, and the second longitudinal screw 1316 is driven to translate on the longitudinal slide 1311 by the threaded engagement between the second longitudinal screw 1315 and the wire sleeve at the bottom of the second longitudinal translation plate 1316.

In this embodiment, the longitudinal fixing plate 1317 is mounted on the longitudinal rail 1311, but a longitudinal translational driving mechanism is not connected, and thus, the longitudinal fixing plate 1317 is a plate body relatively fixed in position. When the first longitudinal translation driving mechanism and the second longitudinal translation driving mechanism drive the first longitudinal translation plate 1313 and the second longitudinal translation plate 1316 to move respectively, the two columns of the first column group on the first longitudinal translation plate 1313 and the two columns of the third column group on the second longitudinal translation plate 1316 move relative to the two columns of the second column group, so that the longitudinal distance between the column groups is adjusted, that is, the longitudinal dimension of the six-column frame supporting mechanism 13 is adjusted.

The transverse adjusting mechanism is used for adjusting the distance between two upright posts in the upright post group, so as to adjust the transverse dimension of the six-post type frame body supporting mechanism 13. The three transverse adjusting mechanisms corresponding to the three sets of upright post groups are connected with synchronous spacing adjusting driving mechanisms. The synchronous spacing adjustment driving mechanism is used for driving each transverse adjustment mechanism and enabling each transverse adjustment mechanism to adjust the spacing of the upright posts synchronously. The synchronous pitch adjustment drive mechanism includes a first vertical petal-axis transmission mechanism 1301, a second vertical petal-axis transmission mechanism 1302, a third vertical petal-axis transmission mechanism 1303, a petal axis 1304, and a width adjustment motor 1305. The lateral adjustment mechanism, as shown in fig. 4, includes a lateral lead screw 1321 and a lateral slide rail 1322. The bottoms of the two upright posts of the upright post group are respectively vertically erected on the transverse sliding rail 1322 through the sliding blocks 1323. The transverse sliding rails 1322 corresponding to the three sets of upright posts are respectively and horizontally erected on the first longitudinal translation plate 1313, the longitudinal fixing plate 1317 and the second longitudinal translation plate 1316. The transverse slide 1322 is perpendicular to the longitudinal slide 1311. The transverse screw 1321 is provided with forward and reverse threads, which are parallel to the transverse slide rails 1322. The bottoms of the two columns of the column groups are respectively connected with the forward threads and the reverse threads of the transverse screw rod 1321 through the screw sleeves, so that when the transverse screw rod 1321 rotates, the two columns of the corresponding column groups can be driven to move on the transverse sliding rail 1322 in opposite directions. The first, second, and third vertical petal-

axis transmission mechanisms

1301, 1302, and 1303 are provided on the petal axis 1304, and are movable along the petal axis 1304. The petal axle 1304 is parallel to the longitudinal rails 1311 and perpendicular to the lateral lead screw 1321 of the lateral adjustment mechanism. The petal shaft 1304 is connected with a transverse screw 1321 of a transverse adjusting mechanism corresponding to the three sets of upright posts through a first vertical petal shaft transmission mechanism 1301, a second vertical petal shaft transmission mechanism 1302 and a third vertical petal shaft transmission mechanism 1303 respectively. The petal shaft 1304 is connected with a width adjusting motor 1305. Thus, when the width adjusting motor 1305 drives the petal shaft 1304 to rotate, the petal shaft 1304 drives the transverse screw 1321 of the transverse adjusting mechanism corresponding to the three sets of upright posts to rotate through the first vertical petal shaft transmission mechanism 1301, the second vertical petal shaft transmission mechanism 1302 and the third vertical petal shaft transmission mechanism 1303, respectively, thereby adjusting the spacing between two upright posts of the three sets of upright posts. The petal shaft 1304 is the same as the spline shaft in patent document CN105798180 a.

The cabinet opening table 111 is arranged in a ring column manner, that is, column holes are formed in the cabinet opening table 111. Six upright posts of the six-post frame body supporting mechanism 13 respectively pass through the corresponding upright post holes. The cabinet opening table 111 is connected with a cabinet opening table lifting mechanism, and is lifted and adjustable through the cabinet opening table lifting mechanism. The cabinet opening table lifting mechanism is used for driving the cabinet opening table 111 to lift and comprises a chain 112, a motor 113 and four sets of wire rod column sleeve mechanisms. The screw post sleeve mechanism includes a screw sleeve post 121, a screw post 122, a drive gear 123, and two clamping gears 124. The silk fibroin 121 is vertically installed on the base 110. The screw post 122 is vertically disposed within the socket hole of the socket post 121. Four screw rod column sleeve mechanisms are respectively positioned at four corners of the base 110. The cabinet opening table 111 is mounted on the top end of the screw rod column 122 and is horizontally arranged. The cabinet opening table 111 is a square plate body, and four corners of the square plate body respectively correspond to one set of wire rod column sleeve mechanism. A horizontal gear cabinet 125 is mounted on top of the silk sleeve column 121. The drive gear 123 is mounted on the screw post 122 above the gear cabinet 125. Two clamping gears 124 are mounted on the gear cabinet 125 on either side of the drive gear 123. The driving gear 123 can be rotated in synchronization with the screw post 122. When the driving gear 123 rotates, the screw rod 122 is driven to rotate. The rotating screw rod column 122 drives the screw rod column 122 to lift through the screw thread action between the screw rod column 122 and the screw sleeve column 121, so that the cabinet opening table 111 is driven to lift. A motor 113 is mounted on the base 110 and is connected to a drive gear 114. Two transition gears 115 are provided on the table on which the driving gear 114 is mounted. The drive gear 123, the clamping gear 124, the drive gear 114, and the transition gear 115 are all located at the same height. The chain 112 crosses around the drive gear 114, the transition gear 115, the drive gear 123 and the clamping gear 124. Wherein, at the driving gear 114 and the transition gears 115, the chain 112 bypasses the driving gear 114 and the two transition gears 115 so that the chain 112 is in an omega structure and simultaneously meshes with the driving gear 114 and the two transition gears 115. At the drive gear 123 and the clamp gear 124, the chain 112 is clamped between the drive gear 123 and the clamp gear 124, and simultaneously meshes with the drive gear 123 and the clamp gear 124. Therefore, when the motor 113 drives the driving gear 114 to rotate, the chain 112 rotates and moves along with the driving gear, so as to drive the driving gears 123 of the screw rod column sleeve mechanisms to rotate, and the cabinet opening table 111 is driven to lift by the threaded engagement action between the screw rod column 122 and the screw sleeve column 121.

In addition, since the bin gate table 111 is horizontal, only a refrigerator liner of a horizontal bin gate can be supported. The refrigerator liner is provided with multiple inclined openings, namely, in the refrigerator with low front and high back, the refrigerator liner is correspondingly provided with the inclined openings with low front and high back. Under the horizontal cabinet opening bench mode, the inclined opening type refrigerator inner container can only support the cabinet opening part with high rear side, and the cabinet opening part with low front side can not be supported. For this reason, the invention adopts two embodiments to realize the support of the inner container of the bevel-mouth refrigerator.

A first embodiment is to mount a telescoping bracket on the post. When the refrigerator liner is a bevel-mouth cabinet, the bracket extends out of the cabinet mouth part with the lower front side. In this embodiment, as shown in fig. 2 and 6, the telescopic bracket mounted on the upright is a diagonal cabinet inner bracket 1336. Three support rods 1336 in the bevel cabinet. The three upright posts on the same side of the three upright post sets are respectively provided with an inner supporting rod 1336 of the bevel cabinet. The supporting rod 1336 in the bevel cabinet is always higher than the table surface of the cabinet mouth table 111, is installed on the corresponding upright posts through the supporting cylinder 1335 in the bevel cabinet and is connected with the piston of the supporting cylinder 1335 in the bevel cabinet, so that the supporting rod 1336 in the bevel cabinet can outwards extend out of the side surface formed by three upright posts on the same side of the three upright post groups under the driving of the supporting cylinder 1335 in the bevel cabinet, and the supporting rod 1336 in the bevel cabinet can support the mouth of the refrigerator liner in the bevel cabinet. Because the bezel cabinet inner brace 1336 is higher than the table top of the cabinet mouth table 111, when the bezel cabinet inner brace 1336 extends, the portion of the bezel cabinet inner container where the cabinet mouth is short is supported by the bezel cabinet inner brace 1336, and the portion of the bezel cabinet inner container where the cabinet mouth is high is supported by the cabinet mouth table 111.

A second embodiment is to mount a retractable bracket on the counter top. When the refrigerator liner is a bevel-mouth cabinet, the bracket extends out of the cabinet mouth part with the lower front side. In this embodiment, as shown in fig. 1 and 5, the telescopic bracket mounted on the cabinet opening table is composed of a plurality of diagonal cabinet outer support rods 119 driven by air cylinders arranged on the cabinet opening table 111. The outer supporting rod 119 of the bevel cabinet is horizontally arranged and can extend to the side face formed by the three upright posts on the same side of the three upright post sets under the driving of the corresponding air cylinders, so that the outer supporting rod 119 of the bevel cabinet can support the cabinet mouth of the bevel-mouth refrigerator liner. The number of the outer supporting rods 119 of the bevel cabinet is preferably 3-4. The bezel counter outer support bar 119 is mounted to the counter top 111 at a height that is always higher than the counter top of the counter top 111. When the bezel cabinet inner brace 1336 is extended, the low-mouth portion of the bezel cabinet inner container is supported by the bezel cabinet outer brace 119, and the high-mouth portion of the bezel cabinet inner container is supported by the bezel table 111.

An adjustable bridge plate link 14 is provided between the top ends of tall posts 1331 or between the top ends of short posts 1332. One end of the adjustable bridge plate link 14 is fixed at the top end of one upright, and the other end bypasses an arc-shaped supporting block 1413 arranged on the other upright to be connected with a bridge link pulling mechanism. The bridge chain pulling mechanism is used for pulling one end of the adjustable bridge plate chain 14 to straighten the adjustable bridge plate chain 14 when the distance between the two upright posts is adjusted, so that the length of the part of the adjustable bridge plate chain 14 between the upright posts can be adjusted synchronously with the adjustment of the distance between the upright posts. The portion of the adjustable bridge plate link 14 between the two uprights is horizontal and does not sag due to slack. The adjustable bridge plate link chain 14 is a one-way bending chain. Specifically, the adjustable bridge plate link 14 has a one-way bending function so that the horizontal portion of the adjustable bridge plate link 14 between the two uprights can arch upward due to slackening, but does not sag due to slackening. The horizontal portion of the adjustable bridge plate link 14 between the two uprights is used to provide support for the riveting of the four horizontal edges of the Z-shaped bottom plate of the liner of the refrigerator. The four horizontal side lines are respectively: the edges corresponding between the two tall posts 1331 of the first post set, the edges corresponding between the two tall posts 1331 of the same side of the first post set and the second post set, and the edges corresponding between the two short posts 1332 of the third post set. Thus, adjustable bridge plate links 14 are typically mounted between two tall posts 1331 of the first post set, between two tall posts 1331 on the same side of the first post set and the second post set, and between two short posts 1332 of the third post set. Of course, the adjustable bridge plate link 14 may also be mounted between two tall posts 1331 of the second group of posts. The mounting position of the adjustable bridge plate links 14 between the uprights depends on the position of the zigzag bottom plate edge of the refrigerator liner processed by the riveting mechanism. The structure of the adjustable bridge plate links 14 mounted between the uprights is shown in figure 7. Fig. 7 shows an arrangement where the adjustable bridge plate link 14 is mounted to two tall posts 1331 of the first post set.

As shown in fig. 7, 8, and 9, two tall posts 1331 are vertically mounted to two carriage plates 1324, respectively. Carriage plate 1324 is vertically mounted to transverse slide rails 1322 by slides 1323. The transverse slide rail 1322 is horizontally disposed on the first longitudinal translation plate 1313. The two high posts 1331 are moved on the transverse slide rails 1322 to adjust the spacing therebetween. The movement of the two high posts 1331 on the lateral slide rails 1322 is driven by the lateral screw 1321 described above. The two high posts 1331 are each a cylinder with an L-shaped cross section. Wherein, the top of the right high upright 1331 is provided with a horizontal first top plate 1411, and the top of the left high upright 1331 is provided with a horizontal second top plate 1451. The top surface of the second top plate 1451 is level with the top surface of the first top plate 1411. The first top plate 1411 is provided with a wedge-shaped support block 1412 toward the inner side of the second top plate 1451. The wedge-shaped support block 1412 has a top surface that is level with the top surface of the first top plate 1411. An arc-shaped support block 1413 is mounted below the wedge-shaped support block 1412. The arc-shaped supporting block 1413 is fixed to the right high upright 1331. A chain channel 1415 is provided between the arcuate support block 1413 and the wedge support block 1412. The arc-shaped supporting block 1413 has an arc surface in a direction toward the wedge-shaped supporting block 1412. One end of the adjustable bridge plate link 14 is secured to a second top plate 1451. The other end bypasses the arc surface on the arc-shaped supporting block 1413 and passes through the chain channel 1415 to be installed on the right high upright 1331 through the bridge chain pulling mechanism. The bridge chain pulling mechanism is used to straighten the adjustable bridge plate chain 14 at one end of the adjustable bridge plate chain 14 when the spacing between the two tall posts 1331 is adjusted.

In this embodiment, the bridge chain pulling mechanism is a rodless cylinder 143 vertically provided on a high upright 1331 on the right side. The rodless cylinder 143 is vertically provided inside the L-shaped cylinder. A piston slide 1431 of the rodless cylinder 143 is fixed to one end of the adjustable bridge plate link 14. When the adjustable bridge plate link 14 is pulled taut and straightened by the bridge pulling mechanism, the portion of the adjustable bridge plate link 14 between the two tall posts 1331 remains horizontal, and the portion of the adjustable bridge plate link 14 between the arcuate support blocks 1413 provided on the right tall post 1331 and the piston slide blocks 1431 remains vertical. When the portion of the adjustable bridge plate link 14 between the two tall posts 1331 is held horizontal, its top surface is flush with the top surfaces of the first and second

top plates

1411, 1451. The gap of the arc-shaped connecting part of the top end of the adjustable bridge plate link 14 positioned on the right side high upright 1331 is compensated by the wedge-shaped supporting blocks 1412, so that the two high uprights 1331 have horizontal supporting surfaces. The horizontal support surface is comprised of the top surface of the first top plate 1411, the top surface of the second top plate 1451, the top surface of the horizontal portion of the adjustable bridge chain 14, and the top surface of the wedge support block 1412.

The structure of the adjustable bridge plate link chain 14 is formed by sequentially connecting link blocks in series as shown in fig. 10, 11 and 12. The link block is composed of a deck plate 1421, a detent plate 1422, and a series connection. The link block composed of the deck plate 1421, the detent plate 1422 and the serial portion is integrally processed of stainless steel. The serial connection part is composed of two shaft hole plates 143. The shaft hole plate 143 has a first shaft hole 1431 and a second shaft hole 1432 at both ends thereof, respectively. The shaft hole plate 143 is provided with a bending portion 1433 so that the shaft hole plate 143 is zigzag. The two shaft holes 143 are oppositely arranged, so that the axes of the first shaft holes 1431 of the two shaft holes 143 are coincident, the axes of the second shaft holes 1432 of the two shaft holes 143 are coincident, and the axes of the first shaft holes 1431 are parallel to the axes of the second shaft holes 1432. The first shaft holes 1431 of the two shaft holes 143 of the serial portion of the link block can be caught inside the second shaft holes 1432 of the two shaft holes 143 of the serial portion of the other link block. When the first shaft holes 1431 on the two shaft holes 143 of the serial connection part of the link blocks are clamped inside the second shaft holes 1432 on the two shaft holes 143 of the serial connection part of the other link block and are connected through the bearing 144, the serial connection between the two link blocks is realized. The plurality of link blocks are connected in series between each other to form the adjustable bridge plate link 14 of this embodiment. Adjacent two link blocks can rotate about the axis of the bearing 144 connecting the two link blocks, thereby enabling the adjustable bridge plate link 14 to bend unidirectionally. The retaining plate 1422 is mounted on the side edges of the two shaft hole plates 143 and is parallel to the axis of the first shaft hole 1431. The deck plate 1421 is mounted on the detent plate 1422 and is parallel to the axis of the first shaft hole 1431. Specifically, the plane formed by the axes of the first shaft hole 1431 and the second shaft hole 1432 of the link block is parallel to the top surfaces of the deck plate 1421 and the detent plate 1422. As shown in fig. 13, the first shaft hole 1431 and the second shaft hole 1432 have a center distance L1, the detent plate 1422 has a width L2, and the deck plate 1421 has a width L3. The axial distance L1 of the first shaft hole 1431 and the second shaft hole 1432, the width L2 of the detent plate 1422, and the width L3 of the deck plate 1421 are the same, that is, l1=l2=l3. The deck plate 1421 and the detent plate 1422 are arranged in a staggered manner, so that a zigzag structure is formed between the deck plate 1421 and the detent plate 1422. The offset distance between the deck plate 1421 and the detent plate 1422 is half the width of the deck plate 1421, that is, L4 in fig. 13 is the offset distance between the deck plate 1421 and the detent plate 1422, l1=l2=l3=2×l4. The staggered deck plate 1421 and the clamping plate 1422 enable two adjacent chain link blocks to rotate in one direction only, and the two adjacent chain link blocks are clamped by the staggered deck plate 1421 and the clamping plate 1422 and cannot be bent when rotating in opposite directions, so that the adjustable bridge plate chain 14 can be bent in one direction only.

In this embodiment, the deck plate 1421 and the detent plate 1422 are plate bodies having a thickness of not less than 0.8 cm, so that the adjustable bridge plate link 14 has sufficient physical strength. And the deck plate 1421 has a square structure. It will be apparent that the top surface of the horizontal portion between the uprights of the adjustable bridge deck chain 14 is stitched together from deck plates 1421 of the individual link blocks. Because the deck plate 1421 is square in configuration, the edges of the spliced deck plate 1421 of each link block have a rectangular square edge. The long straight square right-angle edge is needed by a riveting mechanism for riveting the edge of the Z-shaped bottom plate of the refrigerator liner. The common unidirectional bending chain does not have a right-angle edge, but can not be used for providing support when a riveting mechanism is used for riveting the edge of the Z-shaped bottom plate of the refrigerator liner. In addition, hollow holes 146 are provided in the middle of the deck plate 1421 and the detent plate 1422. The hollowed-out holes 146 are used for saving material cost on the premise of not reducing the physical strength of the plate body.

In addition, in the adjustable bridge plate link 14 of the present embodiment, due to the locking effect of the dislocation structure formed by the deck plate 1421 and the locking plate 1422, when the adjustable bridge plate link 14 is pulled by the bridge link pulling mechanism, the posts cannot move. The adjustable bridge plate link 14 of this embodiment can thus serve to strengthen the support between the uprights. Therefore, the adjustable bridge plate link 14 mounted between the two tall posts 1331 of the second post group can serve as a reinforcing support, although not used for caulking work support. Since six columns of the six-column frame body supporting mechanism 13 are vertically on the two slide rails, the physical strength is liable to be insufficient. For this reason, this embodiment strengthens the physical strength of the column by the cylinder rod locking mechanism. The cylinder slide rod locking mechanism is arranged between the upright posts of the six-post frame body supporting mechanism 13. The cylinder rod locking mechanism includes a horizontal rod 1333 and a locking cylinder 1334. Locking cylinder 1334 is mounted in the middle of the column. The horizontal sliding rod 1333 is connected to the upright column through a locking cylinder 1334. When the locking cylinder 1334 is loosened, the locking cylinder 1334 can horizontally slide along the horizontal sliding rod 1333. When the locking cylinder 1334 is locked, the locking cylinder 1334 fixes the horizontal sliding rod 1333 and the upright post. There are generally two ways of installing the cylinder rod locking mechanism: the first type of installation is to install the cylinder slide rod locking mechanism between three columns on the same side of the three column sets, at this time, the horizontal slide rod 1333 connects the three columns through three locking cylinders 1334. The second type of installation is to install the cylinder slide rod locking mechanism between two posts in the post set, where the horizontal slide rod 1333 connects the two posts through two locking cylinders 1334.
