Description

Technical Field

[0001] The invention relates to the technical field of locking rod devices, and in particular to an anti-deformation locking rod device for a container and a use method thereof. Background Art

[0002] The locking rod device is also called a lock, door lock, etc. The good pressure resistance and stability of the locking rod device can be used in various fields such as automobiles, civil use, and containers. When the container is transported, the container door needs to be locked to achieve the need for the interior of the container to be in a sealed state, which is convenient for the subsequent long-distance transportation of items or goods stored in the container.

[0003] In the prior art, the locking rod device is usually installed in a fixed manner. When the container tilts and falls due to external force, the internal rod of the locking rod device is easily deformed, which makes the locking rod device unable to open and close normally, resulting in insufficient stability of the device. At the same time, since the existing locking rod device often adopts a single locking method when locking, the container is prone to shaking during the movement of the container, and an additional locker is often required to reinforce the locking of the container door, which increases the workload of the staff when unlocking the container and reduces the efficiency of opening and closing the lock. Therefore, a device that can further strengthen the locking rod and simplify the unlocking method is needed to avoid insufficient stability and low efficiency of opening and closing the lock.

The connecting block is slidably matched with both the first box body and the first locking frame. A plurality of positioning blocks are fixedly connected to the side end of the linkage block close to the second box body. The plurality of positioning blocks are arranged at equal intervals. The side end of the positioning block away from the linkage block is slidably arranged in the positioning groove on the side end of the first box body.

[0008] Preferably, the locking component includes a self-locking column which is hollow.

The limiting frame and the self-locking column can be sleeved on the clamping column and are located inside the clamping sleeve. The inner walls of the limiting frame and the self-locking column are in sliding fit with the outer wall of the clamping column. One end of the clamping sleeve away from the self-locking column is fixedly connected with an L-shaped bracket. A fixing groove with the same shape and size as the arc block is formed on the inner wall of the clamping sleeve close to the L-shaped bracket. A through groove with the same size and position as the expansion groove is formed on the L-shaped bracket. Wedge blocks are symmetrically arranged on the upper and lower sides of the clamping sleeve and penetrate through the side wall of the clamping sleeve.

The top of the wedge block is movably connected with the L-shaped bracket through a telescopic spring. When the self-locking column is sleeved on the clamping column inside the clamping sleeve, the side end of the arc block can be pressed against the wedge block.

[0010] Preferably, the reinforcement trigger component includes a control disk. The control disk is rotatably arranged on the side of the L-shaped bracket away from the clamping column. The center of the control disk is connected with a rotating shaft, and one end of the rotating shaft away from the control disk is rotatably connected to the inner wall of the adjacent second box body. A number of arc-shaped chutes are formed on the control disk. Each of the arc-shaped chutes corresponds to the position of a through groove one by one.

[0011] Preferably, the driving component includes a transmission belt. A number of transmission belts are provided.

A driving gear is arranged on the side end of one of the transmission members, and the center of the driving gear is fixedly connected to the adjacent rotating shaft. A third rotating groove is formed on the side of the second box body close to the second locking frame. A linkage gear is rotatably connected in the third rotating groove, and the side end of the linkage gear is meshed with the side end of the driving gear. One side end of the linkage gear away from the driving gear passes through an opening and is located inside the second locking frame. A transmission groove is formed at one end of the locking rod away from the control box, and when the locking rod moves into the second locking frame, the transmission groove can be meshed with the side end of the linkage gear.

[0012] Preferably, a method for using an anti-deformation locking rod device for a container includes the following steps:

[0013] S1: When the staff moves the two push doors closer to each other, the first box body and the second box body are driven to move closer to each other. Subsequently, pinch the outside of the control box by hand, move the two sliding parts towards the control box at the same time, drive the control rod to slide away from the locking rod, so that one end of the positioning rod clamped in the first card slot moves away from the first card slot, so that the locking rod can rotate and slide in the first rotation slot of the first locking frame. Subsequently, drive the limit sleeve to be clamped into the moving slot and rotate. When the locking rod moves to the specified position, release the pressure on the two sliding parts, and then drive the positioning rod to be clamped into the second card slot under the action of the spring damping rod;

[0014] S2: When moving the locking rod from the first rotation slot of the first locking frame towards the second locking frame, drive the linkage block to move towards the second box body synchronously through the connecting block, drive the positioning block to slide through the positioning slot and be clamped between the two mating blocks at the side end of the second box body, and be clamped in the slot, so as to facilitate the preliminary positioning of the positions of the first box body and the second box body;

[0015] S3: When driving the linkage block to move towards the second box body through the locking rod, drive the self-locking column to move into the clamping sleeve synchronously, and then drive the self-locking column and the limit frame to be sleeved on the clamping column in the clamping sleeve, so that one end of the limit rod is clamped into the arc-shaped sliding slot of the control disc through the through slot on the L-shaped bracket. During the movement, the arc block abuts against the wedge block, so that the symmetrically arranged wedge blocks move away from each other under the action of the pulley and the movable rod, and synchronously compress the telescopic spring. Since the circular diameter of the circle formed by several arc blocks is greater than the self-locking column at this time, when several arc blocks pass through the wedge block, the wedge blocks move closer to each other again under the action of the telescopic spring and abut against the side end of the self-locking column, and perform limiting, so as to complete the preliminary locking of the positions of the first box body and the second box body;

[0016] S4: After the wedge block limits the self-locking column, at the same time, one end of the limit rod is synchronously clamped into the arc-shaped chute of the control disk. Subsequently, by driving the locking rod to rotate, the linkage gear is driven to rotate through transmission, so that the meshing driving gear rotates. Under the action of the transmission belt, a number of transmission parts and the rotating shaft rotate synchronously, causing the control disk to rotate. Under the action of the arc-shaped chute, a number of limit rods move away from each other in the expansion slot, so that a number of arc blocks move away from each other centered on the self-locking column along the direction of the sliding slot and are clamped into the fixed slots in the clamping sleeve for reinforcement locking. When unlocking is required, by rotating the locking rod in the reverse direction, a number of arc blocks approach each other along the sliding slot, so that the circular diameter of the combination of a number of arc blocks is smaller than that of the self-locking column. When the locking rod is withdrawn from the second locking frame, it can smoothly pass through the symmetrically arranged wedge blocks. After passing through, it slowly resets through the spring damper, so that the wedge blocks can be smoothly driven to move away from each other when locking next time.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In the present invention, when the device is in use, the staff first moves the two push doors closer to each other, thereby driving the first box body and the second box body closer to each other. Subsequently, by controlling the lock rod fastening device, the linkage positioning component in the first box body is driven to move towards the second box body, so that a number of locking components pass through the slots corresponding to their positions on one side of the second box body and are located in the fixing component, thereby initially locking the positions of the first box body and the second box body, and further fixing the positions of the two sliding doors. Subsequently, by rotating the lock rod fastening device, a number of reinforcement trigger components are driven to work through the driving component, so that a number of locking components work synchronously, further strengthening the connection between the first box body and the second box body, thereby preventing the internal insertion rod of the lock rod device from deforming when the container tilts and drops due to external force, and further preventing the lock rod device from being unable to be normally opened and closed, thus improving the stability of the device. At the same time, when unlocking is required, by rotating the lock rod fastening device in the reverse direction, a number of reinforcement trigger components are driven to work through the driving component, so that a number of locking components work in the opposite direction, facilitating a number of locking components to move away from the fixing component. The staff moves the lock rod fastening device, so that the linkage positioning component drives a number of locking components away from the fixing component, thereby unlocking the first box body and the second box body, and unlocking the two sliding doors, simplifying the unlocking method, reducing the burden on the staff, and improving the efficiency of locking and unlocking, thus achieving the effect of further strengthening the lock rod while simplifying the unlocking method to avoid insufficient stability and low locking and unlocking efficiency.

[0019] In the present invention, when the staff members move two push doors closer to each other, the first box body and the second box body are driven to move closer to each other. Subsequently, the outer side of the control box is pinched by hand, driving the control rod to slide away from the locking rod, so that one end of the positioning rod clamped in the first card slot moves away from the first card slot, enabling the locking rod to rotate and slide in the first rotating slot of the first locking frame. Then, the control box is moved and rotated along the direction of the moving slot. When the locking rod moves to the specified position, the pressure on the two sliding parts is released. Under the action of the spring damping rod, the two sliding parts are driven to reset, causing the control rod to move in the opposite direction. Under the action of the spring rod, the control rod is assisted to drive the positioning rod to be clamped into the second card slot, facilitating the preliminary positioning of the positions of the first box body and the second box body, enabling the two sliding doors to complete the preliminary positioning, and thus improving the convenience of using the device.

[0020] In the present invention, when the locking rod is moved from the first rotating slot of the first locking frame towards the second locking frame, the connecting block synchronously drives the linkage block to move towards the second box body, driving the positioning block to slide through the positioning slot and be clamped between two mating blocks on the side end of the second box body and be clamped in the slot, facilitating the preliminary positioning of the positions of the first box body and the second box body.

[0021] In the present invention, when the locking rod drives the linkage block to move towards the second box body, the self-locking column is synchronously driven to move into the clamping sleeve, and then the self-locking column and the limiting frame are sleeved on the clamping column in the clamping sleeve, enabling one end of the limiting rod to be clamped into the arc-shaped sliding slot of the control disk through the through slot on the L-shaped bracket. During the movement, the arc block abuts against the wedge block. Under the action of the pulley and the movable rod, the symmetrically arranged wedge blocks move away from each other and synchronously compress the telescopic spring. Since the circular diameter formed by several arc blocks at this time is larger than the self-locking column, when several arc blocks pass through the wedge block, the wedge blocks move closer to each other again under the action of the telescopic spring and abut against the side end of the self-locking column for limiting, thus completing the preliminary locking of the positions of the first box body and the second box body.

[0022] In the present invention, after the wedge block limits the self-locking column, at the same time, one end of the limiting rod is synchronously clamped into the arc-shaped sliding groove of the control disk. Subsequently, by driving the locking rod to rotate, the linkage gear is driven to rotate through transmission, so that the meshing driving gear rotates. Under the action of the transmission belt, a plurality of transmission parts and the rotating shaft rotate synchronously, causing the control disk to rotate. Under the action of the arc-shaped sliding groove, a plurality of limiting rods move away from each other in the expansion groove, so that a plurality of arc-shaped blocks move away from each other with the self-locking column as the center along the direction of the sliding groove and are clamped into the fixed grooves in the clamping sleeve, strengthening the locking. Thus, when the container tilts and falls due to external force, the internal insertion rod of the lock rod device will not be deformed, and further, the lock rod device cannot be normally opened or closed, thereby improving the stability of the device. When unlocking is required, by rotating the locking rod in the reverse direction, a plurality of arc-shaped blocks approach each other along the sliding groove, so that the circular diameter of the combination of a plurality of arc-shaped blocks is smaller than that of the self-locking column. When the locking rod is withdrawn from the second locking frame, it can smoothly pass through the symmetrically arranged wedge blocks, and after passing through, it slowly resets through the spring damper, so that the wedge blocks can be smoothly driven to move away from each other during the next locking, thereby completing the unlocking of the first box body and the second box body, and unlocking the two sliding doors, simplifying the unlocking method, thus reducing the burden on the staff and improving the efficiency of locking and unlocking.

Detailed implementation manners

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0040] Please refer to Figures 1 to 15 , the present invention provides a technical solution: an anti-deformation locking rod device for a container, including a container 1, on one side of the container 1, a pair of sliding doors 2 that can be opened and closed are symmetrically provided. On each of the sliding doors 2, a first box body 3 and a second box body 4 are fixedly arranged respectively.

A plurality of locking assemblies 7 for fixing positions when the first box body 3 and the second box body 4 approach each other are provided at equal intervals on the linkage positioning assembly 6. On one side of the second box body 4 close to the first box body 3, a plurality of slots 8 corresponding to the positions of the locking assemblies 7 are opened. In each of the slots 8, a lock column device 9 for cooperating with the locking assemblies 7 is provided. A driving assembly 10 is provided at the side end of the lock column device 9. The lock column device 9 includes a fixing component 91 and a reinforcement trigger component 92. The fixing component 91 is arranged inside the second box body 4, and the reinforcement trigger component 92 is arranged on one side of the fixing component 91.

[0041] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the locking rod fastening device 5 includes a locking rod assembly 51 and a control component 52. The locking rod assembly 51 is located at the side ends of the first box body 3 and the second box body 4, and the control component 52 is located on the locking rod assembly 51. The locking rod assembly 51 includes a first locking frame 511. The bottom of the first locking frame 511 is fixedly connected to the side of the first box body 3 away from the container 1. A second locking frame 512 corresponding to its position is provided at the side end of the first locking frame 511. The bottom of the second locking frame 512 is fixedly connected to the side of the second box body 4 away from the container 1. A first rotation slot 513 is opened on the first locking frame 511. A second rotation slot 514 having the same size as the first rotation slot 513 is opened on the second locking frame 512. A locking rod 515 is inserted in the first rotation slot 513. The locking rod 515 is rotationally matched with both the first rotation slot 513 and the second rotation slot 514;

[0042] The control component 52 includes a limit sleeve 521. The side end of the limit sleeve 521 is fixedly connected to one end of the locking rod 515 close to the first box body 3. The included angle between the limit sleeve 521 and the locking rod 515 is set at 90 degrees. One end of the limit sleeve 521 away from the locking rod 515 is fixedly connected with a control box 522. Symmetrically arranged sliding members 523 are provided in the control box 522. The bottoms of the sliding members 523 are all in sliding fit with the bottom inside the control box 522. One side of each of the two sliding members 523 away from each other slides through the side wall of the control box 522 and is located outside the control box 522. One side of the two sliding members 523 adjacent to each other is connected by a spring damper rod 524. An obliquely arranged control groove 525 is formed at the top of each sliding member 523. The two control grooves 525 are symmetrically arranged. A control rod 526 is arranged on one side of the two sliding members 523 and is located inside the control box 522. The bottom of the control rod 526 is in sliding fit with the bottom inside the control box 522. Oblique rods 527 are respectively fixedly connected to both sides of the control rod 526. Each oblique rod 527 respectively slides through a control groove 525 and is movably connected to the inner wall of the adjacent control box 522 through a spring rod 528. One end of the control rod 526 away from the sliding member 523 is connected with a positioning rod 529. One end of the positioning rod 529 away from the control rod 526 slides through the side wall of the control box 522 and inside the limit sleeve 521, and slides through the locking rod 515 and is clamped in a first card slot 530 at the side end of the first box body 3. A moving groove 531 for the limit sleeve 521 to slide and rotate is formed on the first locking frame 511. A second card slot 532 for the locking rod 515 to be clamped is formed at the top of the first locking frame 511;

[0043] When the staff moves the two push doors closer to each other, the first box body 3 and the second box body 4 are driven to approach each other. Subsequently, the outer side of the control box 522 is pinched by hand, and then, through the spring damping rod 524, the two sliding members 523 are simultaneously moved towards the control box 522. Through the provided control groove 525, the inclined rod 527 is driven to slide the control rod 526 away from the locking rod 515 under the action of the spring rod 528, thereby driving the positioning rod 529 connected thereto to slide along the direction of the limit sleeve 521. As a result, one end of the positioning rod 529 clamped in the first card slot 530 moves away from the first card slot 530, so that the locking rod 515 can rotate and slide in the first rotation groove 513 of the first locking frame 511. Subsequently, by moving the control box 522, the limit sleeve 521 is driven to be clamped in the moving groove 531 and rotate along the direction of the moving groove 531. At the same time, the end of the locking rod 515 close to the second locking frame 512 slides into the second rotation groove 514 and slides and rotates synchronously. When the locking rod 515 moves to the specified position, by releasing the pressure on the two sliding members 523, the two sliding members 523 are driven to reset under the action of the spring damping rod 524, so that the control rod 526 moves in the opposite direction, and under the action of the spring rod 528, the control rod 526 is assisted to drive the positioning rod 529 to be clamped in the second card slot 532, thus facilitating the preliminary positioning of the positions of the first box body 3 and the second box body 4, enabling the two push-pull doors 2 to complete the preliminary positioning, and thereby improving the convenience of using the device.

[0044] In this embodiment, as Figure 4 , Figure 6 and Figure 7 shown, the linkage positioning assembly 6 includes a linkage block 61. The linkage block 61 is slidably arranged in the first box body 3, and one side of the linkage block 61 close to the limit sleeve 521 is fixedly connected to the side end of the adjacent locking rod 515 through a connecting block 62. The connecting block 62 is slidably matched with both the first box body 3 and the first locking frame 511.

When the linkage block 61 slides towards the second box body 4, each positioning block 63 can be clamped between the two fitting blocks 65;

[0045] When the locking lever 515 is moved from the first rotation slot 513 of the first locking frame 511 towards the second locking frame 512, the connecting block 62 synchronously drives the linkage block 61 to move towards the second box body 4, thereby driving the positioning block 63 to slide through the positioning slot 64 and be clamped between two mating blocks 65 on the side end of the second box body 4, and be clamped in the slot 8, so as to facilitate the preliminary positioning of the positions of the first box body 3 and the second box body 4.

[0046] In this embodiment, as Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 shown, the locking assembly 7 includes a self-locking column 71. The self-locking column 71 is hollow. The side end of the self-locking column 71 is fixedly connected to one end of the positioning block 63 close to the second box body 4. The surface of the end of the self-locking column 71 far from the positioning block 63 is evenly provided with a plurality of sliding slots 72. An arc block 73 is slidably arranged in the sliding slot 72. The bottom of the arc block 73 is movably connected to the bottom of the sliding slot 72 through a spring damper 74. A plurality of the arc blocks 73 are combined into a circle on the outer side of the end of the self-locking column 71. When a plurality of the arc blocks 73 are located at the middle position in the sliding slot 72, the circular diameter is larger than that of the self-locking column 71. When a plurality of the arc blocks 73 are located at the bottommost position in the sliding slot 72, the circular diameter is smaller than that of the self-locking column 71. A limiting frame 75 is arranged at the side end of a plurality of the arc blocks 73, and the side end of the limiting frame 75 is fixedly connected to the side end of the self-locking column 71 far from the positioning block 63. The limiting frame 75 is concentrically arranged with the self-locking column 71 and communicated with it. A plurality of expansion slots 76 are evenly opened on the limiting frame 75. The number of the expansion slots 76 is the same as the number of the arc blocks 73. A plurality of the expansion slots 76 are all arranged around the center of the limiting frame 75, and the opening directions all face the center of the limiting frame 75. The side end of each spring damper 74 is fixedly connected to a limiting rod 77, and the end of the limiting rod 77 far from the spring damper 74 slides through an expansion slot 76 and is located outside the limiting frame 75. The side end of the limiting rod 77 is slidably matched with the inner wall of the expansion slot 76;

[0047] The fixed component 91 includes a clamping sleeve 911. The side end of the clamping sleeve 911 is fixedly connected to the inner side wall of the second box body 4. The clamping sleeve 911 is horizontally arranged, and a clamping column 912 is horizontally arranged inside the clamping sleeve 911. The limiting frame 75 and the self-locking column 71 can be sleeved on the clamping column 912 and are located inside the clamping sleeve 911. The inner walls of the limiting frame 75 and the self-locking column 71 are in sliding fit with the outer wall of the clamping column 912. One end of the clamping sleeve 911 away from the self-locking column 71 is fixedly connected with an L-shaped bracket 913. A fixing groove 914 with the same shape and size as the arc block 73 is formed on the inner wall of the clamping sleeve 911 on the side close to the L-shaped bracket 913. A through groove 915 with the same size and position as the expansion groove 76 is formed on the L-shaped bracket 913. Wedge blocks 916 are symmetrically arranged on the upper and lower sides of the clamping sleeve 911 and slide through the side wall of the clamping sleeve 911. One side of the wedge block 916 close to the L-shaped bracket 913 is rotatably arranged on the L-shaped bracket 913 through a pulley 917. The top of the wedge block 916 is fixedly connected with a movable rod 918 and slides through the side wall of the adjacent L-shaped bracket 913. The top of the wedge block 916 is movably connected with the L-shaped bracket 913 through a telescopic spring 919. When the self-locking column 71 is sleeved on the clamping column 912 inside the clamping sleeve 911, the side end of the arc block 73 can press against the wedge block 916;

[0048] The reinforcement trigger component 92 includes a control disk 921. The control disk 921 is rotatably arranged on one side of the L-shaped bracket 913 away from the clamping column 912. The center of the control disk 921 is connected with a rotating shaft 922, and one end of the rotating shaft 922 away from the control disk 921 is rotatably connected to the inner wall of the adjacent second box body 4. A number of arc-shaped chutes 923 are formed on the control disk 921. Each of the arc-shaped chutes 923 corresponds to the position of a through groove 915 one by one. The number of arc-shaped chutes 923 are evenly distributed in a ring on the control disk 921. The limiting rod 77 can be inserted into the arc-shaped chute 923, and the side end of the limiting rod 77 is in sliding fit with the inner wall of the arc-shaped chute 923. A transmission member 924 is connected to one side of the rotating shaft 922 away from the control disk 921 and is concentric with it;

[0049] When driving the linkage block 61 to move towards the second box body 4 through the locking rod 515, the self-locking column 71 is synchronously driven to move into the clamping sleeve 911, and then the self-locking column 71 and the limiting frame 75 are sleeved on the clamping column 912 in the clamping sleeve 911, so that one end of the limiting rod 77 is clamped into the arc-shaped sliding groove 923 of the control disk 921 through the through groove 915 on the L-shaped bracket 913. During the moving process, the arc-shaped block 73 abuts against the wedge-shaped block 916, so that under the action of the pulley 917 and the movable rod 918, the symmetrically arranged wedge-shaped blocks 916 move away from each other and synchronously compress the telescopic spring 919. Since the circular diameter formed by combining several arc-shaped blocks 73 is larger than the self-locking column 71 at this time, when several arc-shaped blocks 73 pass through the wedge-shaped block 916, the wedge-shaped block 916 moves closer to each other again under the action of the telescopic spring 919 and abuts against the side end of the self-locking column 71 for limiting, thereby initially locking the positions of the first box body 3 and the second box body 4.

[0050] In this embodiment, as Figure 13 、 Figure 14 and Figure 15 shown, the driving assembly 10 includes a transmission belt 101. There are several transmission belts 101. The two ends of each transmission belt 101 are respectively sleeved on the side ends of adjacent transmission members 924. A driving gear 102 is provided at the side end of one of the transmission members 924, and the center of the driving gear 102 is fixedly connected to the adjacent rotating shaft 922. A third rotating groove 103 is formed on the side of the second box body 4 close to the second locking frame 512. A linkage gear 104 is rotatably connected in the third rotating groove 103, and the side end of the linkage gear 104 meshes with the side end of the driving gear 102. The side end of the linkage gear 104 away from the driving gear 102 is located in the second locking frame 512 through an opening 105. A transmission groove 106 is formed at the end of the locking rod 515 away from the control box 522, and when the locking rod 515 moves into the second locking frame 512, the transmission groove 106 can be meshed with the side end of the linkage gear 104;

[0051] After the wedge block 916 limits the self-locking column 71, at the same time, one end of the limit rod 77 is synchronously clamped into the arc-shaped chute 923 of the control disk 921. Subsequently, by driving the locking rod 515 to rotate, the linkage gear 104 is driven to rotate through transmission, so that the meshing driving gear 102 rotates. Under the action of the transmission belt 101, a plurality of transmission parts 924 and the rotating shaft 922 rotate synchronously, causing the control disk 921 to rotate. Under the action of the arc-shaped chute 923, a plurality of limit rods 77 move away from each other in the expansion slot 76, so that a plurality of arc blocks 73 move away from each other with the self-locking column 71 as the center along the direction of the sliding slot 72, and are clamped into the fixing slot 914 in the clamping sleeve 911 for reinforcement locking. Thus, when the container 1 tilts and drops due to external force, the internal inserting rod of the lock rod device will not be deformed, and further the lock rod device cannot be normally opened and closed, thereby improving the stability of the device. When unlocking is required, by rotating the locking rod 515 in the reverse direction, a plurality of arc blocks 73 approach each other along the sliding slot 72, so that the circular diameter formed by the combination of a plurality of arc blocks 73 is smaller than the self-locking column 71. When the locking rod 515 is pulled out of the second locking frame 512, it can smoothly pass through the symmetrically arranged wedge blocks 916. After passing through, it slowly resets through the spring damper 74, so that when locking is performed next time, the wedge blocks 916 can be smoothly driven to move away from each other, thereby completing the unlocking of the first box body 3 and the second box body 4, and unlocking the two sliding doors 2, simplifying the unlocking method, thereby reducing the burden on the staff and improving the efficiency of locking and unlocking.

[0052] The usage method and advantages of the present invention: The usage method of the anti-deformation lock rod device for a container is as follows: The working process is as follows:

[0053] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 shown:

[0054] S1: When the staff moves the two push doors closer to each other, the first box body 3 and the second box body 4 are driven to approach each other. Subsequently, by pinching the outside of the control box 522 with the hand, the control rod 526 is driven to slide in a direction away from the locking rod 515, so that the locking rod 515 can rotate and slide in the first rotation groove 513 of the first locking bracket 511. Subsequently, by moving the control box 522, the limit sleeve 521 is driven to be inserted into the moving groove 531 and rotate along the direction of the moving groove 531. When the locking rod 515 moves to a specified position, by releasing the pressure on the two sliding members 523, the two sliding members 523 are driven to reset under the action of the spring damping rod 524, and under the action of the spring rod 528, the control rod 526 is assisted to drive the positioning rod 529 to be inserted into the second card slot 532;

[0055] S2: When the locking rod 515 is moved from the first rotation groove 513 of the first locking bracket 511 towards the second locking bracket 512, the linkage block 61 is synchronously driven to move towards the second box body 4 through the connecting block 62, so that the positioning block 63 slides through the positioning groove 64 and is clamped between the two mating blocks 65 at the side end of the second box body 4 and is clamped in the slot 8, thus facilitating the preliminary positioning of the positions of the first box body 3 and the second box body 4;

[0056] S3: When the locking rod 515 drives the linkage block 61 to move towards the second box body 4, the self-locking column 71 is synchronously driven to move into the positioning sleeve 911, and then the self-locking column 71 and the limit bracket 75 are sleeved on the positioning column 912 in the positioning sleeve 911, so that one end of the limit rod 77 is inserted into the arc-shaped sliding groove 923 of the control disc 921 through the through groove 915 on the L-shaped bracket 913. During the moving process, by the arc block 73 abutting against the wedge block 916, under the action of the pulley 917 and the movable rod 918, the symmetrically arranged wedge blocks 916 move away from each other and synchronously compress the telescopic spring 919. Since the circular diameter formed by the combination of several arc blocks 73 is larger than the self-locking column 71 at this time, when several arc blocks 73 pass through the wedge block 916, the wedge block 916 moves closer to each other again under the action of the telescopic spring 919 and abuts against the side end of the self-locking column 71 and performs limiting, thus completing the preliminary locking of the positions of the first box body 3 and the second box body 4;

[0057] S4: After the wedge block 916 limits the self-locking column 71, at the same time, one end of the limit rod 77 is synchronously clamped into the arc-shaped chute 923 of the control disk 921. Subsequently, by driving the locking rod 515 to rotate, the linkage gear 104 is driven to rotate through transmission, so that the meshing driving gear 102 rotates. Under the action of the transmission belt 101, a plurality of transmission parts 924 and the rotating shaft 922 rotate synchronously, causing the control disk 921 to rotate. Under the action of the arc-shaped chute 923, a plurality of limit rods 77 move away from each other in the expansion slot 76, so that a plurality of arc blocks 73 move away from each other centered on the self-locking column 71 along the direction of the sliding slot 72 and are clamped into the fixing slots 914 in the clamping sleeve 911 for reinforcement and locking. When unlocking is required, by rotating the locking rod 515 in the reverse direction, a plurality of arc blocks 73 approach each other along the sliding slot 72, so that the circular diameter formed by the combination of a plurality of arc blocks 73 is smaller than that of the self-locking column 71. When the locking rod 515 is withdrawn from the second locking frame 512, it can smoothly pass through the symmetrically arranged wedge blocks 916. After passing through, it slowly resets through the spring damper 74, so that the wedge blocks 916 can be smoothly driven to move away from each other during the next locking.

Then, by pinching the outside of the control box (522) with the hand, the control rod (526) is driven to slide in a direction away from the locking rod (515), so that one end of the positioning rod (529) clamped in the first card slot (530) moves in a direction away from the first card slot (530), so that the locking rod (515) can rotate and slide in the first rotating groove (513) of the first locking frame (511). Then, by moving the control box (522), the limiting sleeve (521) is driven to rotate along the direction of the moving groove (531). When the locking rod (515) moves to the specified position, by releasing the pressure on the two sliding members (523), under the action of the spring damper rod (524), the control rod (526) moves in the opposite direction, and under the action of the spring rod (528), the control rod (526) is assisted to drive the positioning rod (529) to be clamped into the second card slot (532). S2: When the locking rod (515) is moved from the first rotating groove (513) of the first locking frame (511) towards the second locking frame (512), the connecting block (62) synchronously drives the linkage block (61) to move towards the second box body (4), so as to drive the positioning block (63) to slide through the positioning slot (64) and be clamped between the two mating blocks (65) at the side end of the second box body (4) and be clamped in the slot (8), so as to facilitate the preliminary positioning of the positions of the first box body (3) and the second box body (4). S3: Drive the self-locking column (71) and the limit frame (75) to sleeved on the positioning column (912) inside the positioning sleeve (911), so that one end of the limit rod (77) is clamped into the arc-shaped chute (923) of the control disc (921) through the through groove (915) on the L-shaped bracket (913). During the movement, the arc-shaped block (73) abuts against the wedge-shaped block (916), causing the symmetrically arranged wedge-shaped blocks (916) to move away from each other and simultaneously compress the telescopic spring (919). Since the circular diameter formed by the combination of several arc-shaped blocks (73) is greater than that of the self-locking column (71) at this time, when several arc-shaped blocks (73) pass through the wedge-shaped block (916), the wedge-shaped block (916) moves closer to each other again under the action of the telescopic spring (919) and abuts against the side end of the self-locking column (71) for positioning, thus initially locking the positions of the first box body (3) and the second box body (4). S4: After the wedge-shaped block (916) positions the self-locking column (71), at the same time, one end of the limit rod (77) is synchronously clamped into the arc-shaped chute (923) of the control disc (921). Then, by driving the locking rod (515) to rotate, the control disc (921) rotates. Under the action of the arc-shaped chute (923), several arc-shaped blocks (73) move away from each other centered on the self-locking column (71) along the direction of the sliding groove (72) and are clamped into the fixed groove (914) inside the positioning sleeve (911) to strengthen the locking. When unlocking is required, by rotating the locking rod (515) in the reverse direction, the circular diameter formed by the combination of several arc-shaped blocks (73) is made smaller than that of the self-locking column (71). When the locking rod (515) is pulled out of the second locking frame (512), it can smoothly pass through the symmetrically arranged wedge-shaped blocks (916).
