DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] As shown in the figure, Figures 1-3 A preferred embodiment of the utility model puts forward an automatic interlocking device, which can lock the trolley and the production line together, and adopts a mechanical unlocking structure, so that the trolley can automatically release the blocking and limiting of the product when being locked and connected with the production line, so as to transfer the product from the trolley to the production line.

[0029] The automatic interlocking releasing device mainly comprises first fixed plate 1, second fixed plate 2, swing lever, top block 5, locking piece 6 and lock pin 7 and the like, wherein the swing lever is provided with two, which are first swing lever 3 and second swing lever 4, and the top block 5 is also provided with two, which correspond to the first swing lever 3 and the second swing lever 4 respectively.

[0030] The first fixed plate 1 and the second fixed plate 2 are vertically arranged and parallel to each other, the first fixed plate 1 can be installed on the trolley, and the second fixed plate 2 can be installed at the front end of the production line, or the positions of the two can be interchanged. The first swing lever 3 is rotatably connected to the side of the first fixed plate 1 close to the end position, and the top block 5 is fixedly installed on the second fixed plate 2 and faces the first swing lever 3. Similarly, the second swing lever 4 is rotatably connected to the side of the second fixed plate 2 close to the end position, and the other top block 5 is fixedly installed on the first fixed plate 1 and faces the first swing lever 3. The first swing lever 3 and the second swing lever 4 are symmetrically arranged, and the two top blocks 5 are also symmetrically arranged.

[0031] As shown in the figure, Figures 2-4 The structure of the first swing lever 3 is the same as that of the second swing lever 4. One end of the swing lever is protruded to form a blocking part 301, and the other end is fixedly installed with a contact rod 8 which is perpendicular to the swing lever, so that the overall shape of the swing lever presents an "L" shape. The pivot is rotatably connected to one end of the swing lever close to the blocking part 301, so that the center of gravity of the swing lever is close to one end of the contact rod 8. Therefore, in the natural state, since one end of the swing lever with the contact rod 8 is heavier, one end of the swing lever with the contact rod 8 swings downward, and one end with the blocking part 301 swings upward, so that the swing lever can block the product.

[0032] In this embodiment, the first fixed plate 1 can be fixedly installed on the trolley, so that the first swing lever 3 can block the product on the trolley to prevent the product from sliding out of the trolley. The second fixed plate 2 can be installed at the front end of the production line, so that the second swing lever 4 can block the product on the production line to prevent the product from sliding out of the production line.

[0033] The blocking part 301 at the upper end of the swing arm acts as a positioning and blocking element for the product. A clearance groove is provided at a corresponding position on the upper edge of the first fixed plate 1 and the second fixed plate 2 to allow the blocking part 301 to pass. When the upper end of the first swing arm 3 (i.e., the end with the blocking part 301) swings downwards, the blocking part 301 can be accommodated in the clearance groove, releasing the obstruction of the product on the trolley. Similarly, the blocking part 301 on the second swing arm 4 can also be accommodated in the clearance groove on the upper edge of the second fixed plate 2, so that the product on the trolley can be transferred to the production line.

[0034] The clearance groove can also serve as a limit to prevent the end of the swing arm with the blocking part 301 from swinging downwards excessively.

[0035] refer to Figure 2 , Figure 3 Each top block 5 has a ramp at its front end, and the height of the top block 5 is appropriately higher than the height of the contact rod 8. When the first fixing plate 1 approaches the second fixing plate 2, the front end of the contact rod 8 will gradually contact the ramp on the top block 5 and slide relative to it along the ramp. During this process, the contact rod 8 will gradually rise, causing the end of the swing rod with the contact rod 8 to gradually rise, while the end of the contact rod 8 with the blocking part 301 will gradually fall downward, thereby releasing the blocking limit.

[0036] In this embodiment, in order to facilitate better contact between the contact rod 8 and the top block 5, the front end of the contact rod 8 also has an inclined surface that matches the inclined surface on the top block 5, thereby reducing resistance.

[0037] In other technical solutions, a bevel may be provided only at the front end of the contact rod 8, without a bevel on the top block 5. Alternatively, a bevel may be provided on the top block 5, but not on the contact rod 8.

[0038] In this embodiment, the locking member 6 is rotatably connected to the middle region of the side of the first fixing plate 1 via a rotating shaft, and correspondingly, the locking pin 7 is fixedly installed in the middle region of the side of the second fixing plate 2. In other technical solutions, the installation positions of the locking member 6 and the locking pin 7 can also be interchanged.

[0039] like Figure 5 As shown, the locking member 6 mainly consists of a main body 61, a limiting part 62, and a locking part 63. The limiting part 62 and the locking part 63 are parallel and integrally connected to one side of the main body, so that the locking member 6 has an "n" shape. A limiting groove 601 is formed between the limiting part 62 and the locking part 63, and a locking groove 602 is provided on the lower edge of the locking part 63.

[0040] The lock pin 7 is cylindrical, when the rotating locking member 6 is rotated, the locking groove 602 on the rotating locking member 6 will be engaged with the lock pin 7, thus the trolley and the production line can be locked left and right. In order to prevent the trolley from moving forward and backward, the lock pin 7 is provided with a disc 701 at the front end, the diameter of the disc 701 is larger than the diameter of the lock pin 7, thus when the rotating locking member 6 is rotated, the disc 701 will be embedded into the limiting groove 601, at the same time, the lock pin 7 will be engaged with the locking groove 602, the disc 701 can prevent the lock pin 7 from being disengaged from the locking groove 602, thus the trolley and the production line can be locked forward and backward, the trolley will not move left and right and forward and backward.

[0041] The length of the limiting part 62 on the rotating locking member 6 is slightly longer than the length of the locking part 63, and extends below the first swing lever 3 and is located on the rotating path of the end of the first swing lever 3 which has the blocking part 301. At the same time when the blocking and limiting of the first swing lever 3 is released, the front end of the limiting part 62 on the rotating locking member 6 will extend to the rotating path of the swing lever, the first swing lever 3 will press the rotating locking member 6 downward during the rotating process, so that the rotating locking member 6 rotates synchronously, the rotating direction is opposite to the rotating direction of the first swing lever 3, and the locking groove 602 on the rotating locking member 6 will be engaged with the lock pin 7 on the second fixed plate 2, so as to lock the trolley and the production line.

[0042] The width of the locking groove 602 is slightly larger than the thickness of the disc 701 at the front end of the lock pin 7, so that the trolley has a forward and backward moving allowance. When unlocking, the trolley is slightly retreated, at this time, the end of the first swing lever 3 which has the blocking part 301 gradually swings upward, thus the rotating locking member 6 can be rotated and disengaged from the lock pin 7, and the unlocking is completed.

[0043] In the embodiment, the rotating locking member 6 is located below and right of the first swing lever 3, preferably, when the first swing lever 3 rotates clockwise, the end of the first swing lever 3 which has the blocking part 301 can press the limiting part 62 of the rotating locking member 6 downward, so that the rotating locking member 6 rotates counterclockwise, and thus the locking with the lock pin 7 is completed. In other technical solutions, the rotating locking member 6 can also be arranged above and left of the first swing lever 3, when the first swing lever 3 rotates clockwise, the end of the first swing lever which has the contact lever 8 swings upward, so as to press the rotating locking member 6 upward, so that the rotating locking member 6 rotates counterclockwise, and thus the locking with the lock pin 7 is completed.

[0044] The first fixed plate 1 is fixedly installed on the mounting plate 10, the mounting plate 10 can be used to be installed on the trolley, the width of the mounting plate 10 is basically consistent with the width of the trolley. In order to further limit the left and right movement of the trolley, the second fixed plate 2 is provided with a butt joint block 9 at each end, the butt joint block 9 is perpendicular to the second fixed plate 2, the distance between the two butt joint blocks 9 is slightly larger than the width of the mounting plate 10, and the left and right sides of the trolley can be limited by the two butt joint blocks 9.

[0045] Reference Figure 2In order to prevent the trolley from colliding with the production line, a bumper 11 is arranged on the mounting plate 10 at both sides of the first fixing plate 1, which plays a buffering role and reduces the impact of the trolley on the production line.

[0046] The above technical solution only embodies the preferred technical solution of the technical scheme of the utility model, and some changes made by the person skilled in the art to some parts thereof all embody the principle of the utility model and are within the protection scope of the utility model.
