Abstract
Description
Technical Field
[0001] This utility model relates to the field of container equipment technology, specifically to a container door hook anti-theft locking mechanism. Background Technology
[0002] Taking the common gantry-type locking structure as an example, when traditional devices are fixed on the gantry, due to the limitations of their own structural design, they cannot achieve stable fixation by relying solely on their own components. In actual use, additional supports must be used to support the locking structure. This not only increases the complexity and cost of installation but also prolongs the operation time. For example, in emergency loading and unloading scenarios outdoors, finding and installing additional supports will seriously affect the efficiency of operations. Moreover, additional supports are easily lost or damaged during transportation, causing the locking device to malfunction and greatly affecting the safety and reliability of the container door. Therefore, a container door hook anti-theft locking mechanism is proposed to solve the above problems. Utility Model Content
[0003] This utility model proposes a container door hook anti-theft locking mechanism, which solves the problem that the container door hook anti-theft locking mechanism in the related technology must rely on additional supports to support the locking structure, which increases the complexity and cost of installation.
[0004] The technical solution of this utility model is as follows: a container door hook anti-theft locking mechanism, including a container door, on which two sets of door rods are symmetrically arranged. A first locking block is sleeved on the outer wall of one set of door rods, and a second locking block is sleeved on the outer wall of the other set of door rods. An insert is fixedly connected to the surface of the second locking block. A locking insert plate is inserted inside the insert. An array of adjustment and limiting holes is evenly opened on the surface of the locking insert plate. The locking insert plate passes through the first locking block and the second locking block. The first locking block, the second locking block, and the insert are fixedly locked by the locking insert plate. A limiting anti-theft nail is embedded and fixed inside the insert. A first malleable winding rod is wound around the top of both the first locking block and the second locking block, and a second malleable winding rod is wound around the bottom of both the first locking block and the insert.
[0005] Optionally, one end of the anti-theft pin is fixedly connected to a pull handle, and the pull handle has anti-slip texture.
[0006] Optionally, the corners of the first locking block, the second locking block, the insert block, and the locking insert plate are all chamfered and rounded.
[0007] Optionally, the locking plate and the insert block are slidably fitted together, and the limiting anti-theft nail and the adjusting limiting hole correspond to each other.
[0008] Optionally, a first stabilizing block is fixedly connected to one end of the first plastic winding rod, and a rubber friction pad is adhesively provided on the inner wall of the first stabilizing block.
[0009] Optionally, a second stabilizing block is fixedly connected to one end of the second plastic winding rod, and a magnetic pad is fixedly connected to the inner wall of the second stabilizing block.
[0010] Optionally, two sets of the first malleable winding rod and the first stabilizing block are wound around the top of the first locking block, and two sets of the second malleable winding rod and the second stabilizing block are wound around the bottom of the first locking block. The number of the first malleable winding rod, the first stabilizing block, the second malleable winding rod, and the second stabilizing block on the second locking block corresponds to the number of the first locking block.
[0011] Optionally, the first stabilizing block and the second stabilizing block are arranged in a semi-circular shape, and the first stabilizing block and the second stabilizing block are attached to the outer wall surface of the door frame.
[0012] The working principle and beneficial effects of this utility model are as follows: Through the cooperation of the first locking block, the second locking block, the insert block, and the locking insert plate, an effective locking mechanism is formed, which can be firmly fixed on the door frame without additional support. The setting of the adjustable limit hole allows the mechanism to adapt to door frames with different spacing, greatly improving the applicability of the equipment. In addition, the first and second plastic winding rods and the corresponding stabilizing blocks enhance the friction and adsorption force, reduce shaking, and improve the fixing effect. Furthermore, the chamfering and rounding treatment of the corners avoids injury to the user, and the anti-slip texture of the handle facilitates operation, thus improving the overall user experience and safety.

[0025] Refer to the instruction manual appendix Figure 1-5The anti-theft locking mechanism for a container door includes a container door 1. Two sets of door rods 2 are symmetrically arranged on the container door 1. A first locking block 3 is fitted onto the outer wall of one set of door rods 2, and a second locking block 4 is fitted onto the outer wall of the other set of door rods 2. An insert block 5 is fixedly connected to the surface of the second locking block 4. A locking plate 6 is inserted inside the insert block 5. An array of adjusting and limiting holes 7 are evenly distributed on the surface of the locking plate 6. The locking plate 6 passes through the first locking block 3 and the second locking block 4. The first locking block 3, the second locking block 4, and the insert block 5 are fixedly locked by the locking plate 6. Limiting anti-theft nails 8 are embedded and fixed inside the insert block 5. A first malleable winding rod 10 is wound around the top of both the first locking block 3 and the second locking block 4, and a second malleable winding rod 12 is wound around the bottom of both the first locking block 3 and the insert block 5. The mechanism works by installing the first locking block 3 on the door rod 2 and the second locking block 4 on the other door rod 2, followed by locking... The insertion of the insert plate 6 into the insert block 5 forms a locking mechanism for the container door 1. At this time, the door rod 2 can be wound by the first plastic winding rod 10 and the first stabilizing block 11 to increase friction and reduce shaking. Then, the door rod 2 is attracted by the second plastic winding rod 12 and the second stabilizing block 13 to achieve the effect of fixing and stabilizing. At this time, the first locking block 3 and the second locking block 4 can be fixed on the door rod 2, which solves the problem that traditional locking devices require additional support on the door rod 2 for fixing, which is more cumbersome.
[0026] Then, a pull handle 9 is fixedly connected to one end of the anti-theft pin 8. The pull handle 9 has anti-slip texture. By holding the pull handle 9, the locking plate 6 can be better inserted into the first locking block 3, the insert block 5 and the second locking block 4, and it has a certain anti-slip and anti-dislodge effect.
[0027] Subsequently, the corners of the first locking block 3, the second locking block 4, the insert block 5, and the locking plate 6 are all chamfered and rounded. The chamfering and rounding process ensures that users will not be scratched or uncomfortable by the sharp edges when operating the first locking block 3, the second locking block 4, the insert block 5, and the locking plate 6.
[0028] Next, the locking plate 6 and the plug block 5 are slidably fitted together, and the limiting anti-theft nail 8 and the adjusting limiting hole 7 correspond to each other; by adjusting the setting of the limiting hole 7, the distance between the first locking block 3 and the second locking block 4 can be adjusted, so that it can be used for door bars 2 with different distances, thereby improving the applicability of the equipment.
[0029] At this time, a first stabilizing block 11 is fixedly connected to one end of the first plastic winding rod 10, and a rubber friction pad is bonded to the inner wall of the first stabilizing block 11. Through the above structure, the first stabilizing block 11 can generate a large friction force with the outer wall surface of the door rod 2, thereby generating a strong pulling force on the first locking block 3 and the second locking block 4, reducing the shaking on the first locking block 3 and the second locking block 4.
[0030] Next, a second stabilizing block 13 is fixedly connected to one end of the second plastic winding rod 12, and a magnetic pad is fixedly connected to the inner wall of the second stabilizing block 13. Through the above structure, the second stabilizing block 13 can be fixed on the outer wall of the door rod 2. At this time, the first locking block 3 and the second locking block 4 above can generate a supporting force, thereby fixing the first locking block 3 and the second locking block 4 on the door rod 2.
[0031] Secondly, two sets of the first malleable winding rod 10 and the first stabilizing block 11 are wound around the top of the first locking block 3, and two sets of the second malleable winding rod 12 and the second stabilizing block 13 are wound around the bottom of the first locking block 3. The number of the first malleable winding rod 10, the first stabilizing block 11, the second malleable winding rod 12 and the second stabilizing block 13 on the second locking block 4 corresponds to the number of the first locking block 3. The winding arrangement of the second malleable winding rod 12 and the first malleable winding rod 10 further links the second stabilizing block 13 and the first stabilizing block 11 to ensure the fixing effect of the first locking block 3 and the second locking block 4.
[0032] Finally, the first stabilizing block 11 and the second stabilizing block 13 are arranged in a semi-circular shape and are attached to the outer wall surface of the door rod 2. The semi-circular arrangement allows the first stabilizing block 11 and the second stabilizing block 13 to better fit the door rod 2, increasing the contact area and friction.
[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
