[0002] Currently, locking devices are widely used in loading and unloading operations of various goods. They securely lock the goods to the transport platform, ensuring the stability and safety of the goods during transportation. However, existing, reliable locking devices generally suffer from problems such as easy shaking during locking, which causes accelerated wear of components. At the same time, the unlocking operation is complicated and cumbersome, seriously affecting loading and unloading efficiency. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the current reliable locking devices, the present invention provides a reliable locking mechanism, convenient unlocking, and can effectively improve loading and unloading efficiency.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] A reliable locking device includes a mounting frame, a fixed base, and a locking assembly rotatably connected to the fixed base. The mounting frame has an internal mounting space, within which the locking assembly and the fixed base are located. The locking assembly includes a first transmission member, a second transmission member, and a drive rod rotatably connected to the fixed base. A through hole is provided on the overlapping portion of the first transmission member, the second transmission member, and the drive rod. A pin passes through the through hole, allowing the first transmission member, the second transmission member, and the drive rod to rotate axially. One end of the second transmission member is connected to a locking member. The upper end of the mounting frame has a groove, and the bottom end of the groove has a moving hole for the locking member to move up and down. A limiting assembly is provided inside the mounting frame. The limiting assembly includes a limiting support plate disposed on the inner sidewall of the mounting frame. When the locking member is under pressure, the limiting support plate provides support to the first transmission member to achieve reliable locking of the locking assembly. By applying a pulling force to the drive rod, the first and second transmission members move closer together, causing the locking member to move downwards to switch the locking member from a locked state to an unlocked state.

[0006] According to one aspect of the present invention, the locking member includes a connecting part, a limiting part, and a transmission part connected sequentially from top to bottom.

[0007] According to one aspect of the present invention, the limiting component further includes a limiting block disposed between the transmission part and the side wall of the groove.

[0008] According to one aspect of the present invention, the diameter of the limiting portion is larger than the diameter of the connecting portion or the transmission portion.

[0009] According to one aspect of this utility model, a washer is fitted onto the connecting part.

[0010] According to one aspect of the present invention, the first transmission member includes two opposing first transmission plates, and the second transmission member is disposed between the two first transmission plates.

[0011] According to one aspect of the present invention, the limiting support plate includes two limiting support plates disposed on the same side inside the mounting frame.

[0012] According to one aspect of the present invention, the limiting support plate abuts against the first transmission plate.

[0013] According to one aspect of the present invention, the second transmission member includes two opposing second transmission plates, and the drive rod is disposed between the two second transmission plates.

[0014] According to one aspect of this utility model, the drive rod is connected to a hydraulic cylinder.

[0015] The advantages of this utility model are: the limiting component provides support when the locking member is under pressure, making the locking reliable and the structure stable; the drive rod makes the first and second transmission components move closer or further apart, thereby driving the locking member to move longitudinally to achieve locking or unlocking, which is simple and convenient to operate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] like Figures 1 to 4 As shown, a reliable locking device includes a mounting frame 9, a fixed base 1, and a locking assembly rotatably connected to the fixed base 1. The mounting frame 9 has an internal mounting space, within which the locking assembly and the fixed base 1 are located. The locking assembly includes a first transmission member 2, a second transmission member 3, and a drive rod 4 rotatably connected to the fixed base 1. A through hole is provided on the overlapping portion of the first transmission member 2, the second transmission member 3, and the drive rod 4. A pin 8 passes through the through hole, allowing the first transmission member 2, the second transmission member 3, and the drive rod 4 to rotate about its axial direction. One end of the second transmission component 3 is connected to a locking component 5. The upper end of the mounting frame 9 is provided with a groove 7, and the bottom end of the groove 7 is provided with a moving hole for the locking component 5 to move up and down. The mounting frame 9 is provided with a limiting component, which includes a limiting support plate 22 disposed on the inner side wall of the mounting frame 9. When the locking component 5 is under pressure, the limiting support plate 22 provides support for the first transmission component 2 to achieve a secure locking of the locking component. By applying a pulling force to the drive rod 4, the first transmission component 2 and the second transmission component 3 are brought closer to each other, driving the locking component 5 to move downward to achieve the switching of the locking component 5 from the locked state to the unlocked state.

[0027] When in use, the locking member 5 is locked to the goods. After the locking member 5 is under pressure, it moves downward. The limiting support plate 22 provides support and reduces the shaking of the locking member 5. When it is necessary to unlock, a pulling force is applied to the drive rod 4, so that the first transmission member 2 and the second transmission member 3 move closer to each other, driving the locking member 5 to move downward so as to switch the locking member 5 from the locked state to the unlocked state.

[0028] like Figure 5 As shown, the limiting support plate 22 is disposed in the middle of the side wall. The limiting support plate 22 has a larger contact area with the first transmission member 2, further improving the support effect.

[0029] In practical applications, the locking member 5 includes a connecting part 51, a limiting part 52, and a transmission part 53 connected sequentially from top to bottom. The connecting part 51 is used to connect goods, containers, etc., and the transmission part 53 is rotatably connected to the second transmission member 3 to achieve transmission.

[0030] In practical applications, the limiting assembly further includes a limiting block 531 disposed between the transmission part 53 and the side wall of the groove 7. The limiting block 531 cooperates with the limiting part 52 to limit the locking member 5.

[0031] In practical applications, the diameter of the limiting part 52 is larger than the diameter of the connecting part 51 or the transmission part 53. The limiting part 52 limits the movement of the locking member 5 to prevent it from exceeding the preset range of motion and causing wear.

[0032] In practical applications, a washer 6 is fitted onto the connecting part 51. The washer 6 reduces wear and extends the product's service life.

[0033] In practical applications, the diameter of washer 6 is not greater than the diameter of the limiting part 52. This prevents uneven force on washer 6.

[0034] In practical applications, the first transmission component 2 includes two opposing first transmission plates 21, and the second transmission component 3 is disposed between the two first transmission plates 21.

[0035] In practical applications, the first transmission component 2 includes two opposing first transmission plates 21, and the second transmission component 3 is located between the two first transmission plates 21. The transmission structure is more stable.

[0036] Specifically, a washer 6 is provided between the first transmission plate 21 and the fixed base 1. The washer 6 reduces the lateral clearance and enhances the structural stability.

[0037] In practical applications, the second transmission component 3 includes two opposing second transmission plates 31, with the drive rod 4 positioned between the two second transmission plates 31. This results in a more robust transmission structure.

[0038] In practical applications, the drive rod 4 is connected to a hydraulic cylinder. Using a hydraulic cylinder makes operation more convenient.

[0039] The advantages of this invention are: the limiting component provides support when the locking member 5 is under pressure, making the locking reliable and the structure stable; the drive rod 4 causes the first transmission member 2 and the second transmission member 3 to move closer to each other, thereby driving the locking member 5 to move longitudinally to unlock, making the operation simple and convenient.

[0040] Example 2:

[0041] like Figures 1 to 4As shown, a reliable locking device includes a mounting frame 9, a fixed base 1, and a locking assembly rotatably connected to the fixed base 1. The mounting frame 9 has an internal mounting space, within which the locking assembly and the fixed base 1 are located. The locking assembly includes a first transmission member 2, a second transmission member 3, and a drive rod 4 rotatably connected to the fixed base 1. A through hole is provided on the overlapping portion of the first transmission member 2, the second transmission member 3, and the drive rod 4. A pin 8 passes through the through hole, allowing the first transmission member 2, the second transmission member 3, and the drive rod 4 to rotate about its axial direction. One end of the second transmission component 3 is connected to a locking component 5. The upper end of the mounting frame 9 is provided with a groove 7, and the bottom end of the groove 7 is provided with a moving hole for the locking component 5 to move up and down. The mounting frame 9 is provided with a limiting component, which includes a limiting support plate 22 disposed on the inner side wall of the mounting frame 9. When the locking component 5 is under pressure, the limiting support plate 22 provides support for the first transmission component 2 to achieve a secure locking of the locking component. By applying a pulling force to the drive rod 4, the first transmission component 2 and the second transmission component 3 are brought closer to each other, driving the locking component 5 to move downward to achieve the switching of the locking component 5 from the locked state to the unlocked state.

[0042] When in use, the locking member 5 is locked to the goods. After the locking member 5 is under pressure, it moves downward. The limiting support plate 22 provides support and reduces the shaking of the locking member 5. When it is necessary to unlock, a pulling force is applied to the drive rod 4, so that the first transmission member 2 and the second transmission member 3 move closer to each other, driving the locking member 5 to move downward so as to switch the locking member 5 from the locked state to the unlocked state.

[0043] like Figure 6 As shown, the limiting support plate 22 includes two limiting support plates 22 disposed on the same side inside the mounting bracket 9, with a gap between the two limiting support plates 22 for the drive rod 4 to move. When the drive rod 4 and the limiting support plate 22 are disposed on the same side, the gap allows the drive rod 4 to move easily.

[0044] In practical applications, the locking member 5 includes a connecting part 51, a limiting part 52, and a transmission part 53 connected sequentially from top to bottom. The connecting part 51 is used to connect goods, containers, etc., and the transmission part 53 is rotatably connected to the second transmission member 3 to achieve transmission.

[0045] In practical applications, the limiting assembly further includes a limiting block 531 disposed between the transmission part 53 and the side wall of the groove 7. The limiting block 531 cooperates with the limiting part 52 to limit the locking member 5.

[0046] In practical applications, the diameter of the limiting part 52 is larger than the diameter of the connecting part 51 or the transmission part 53. The limiting part 52 limits the movement of the locking member 5 to prevent it from exceeding the preset range of motion and causing wear.

[0047] In practical applications, a washer 6 is fitted onto the connecting part 51. The washer 6 reduces wear and extends the product's service life.

[0048] In practical applications, the diameter of washer 6 is not greater than the diameter of the limiting part 52. This prevents uneven force on washer 6.

[0049] In practical applications, the first transmission component 2 includes two opposing first transmission plates 21, and the second transmission component 3 is disposed between the two first transmission plates 21.

[0050] In practical applications, the first transmission component 2 includes two opposing first transmission plates 21, and the second transmission component 3 is located between the two first transmission plates 21. The transmission structure is more stable.

[0051] Specifically, a washer 6 is provided between the first transmission plate 21 and the fixed base 1. The washer 6 reduces the lateral clearance and enhances the structural stability.

[0052] The limiting support plate abuts against the first transmission plate, and provides support to the first transmission plate through the limiting support plate.

[0053] In practical applications, the second transmission component 3 includes two opposing second transmission plates 31, with the drive rod 4 positioned between the two second transmission plates 31. This results in a more robust transmission structure.

[0054] In practical applications, the drive rod 4 is connected to a hydraulic cylinder. Using a hydraulic cylinder makes operation more convenient.

[0055] The advantages of this invention are: the limiting component provides support when the locking member 5 is under pressure, making the locking reliable and the structure stable; the drive rod 4 causes the first transmission member 2 and the second transmission member 3 to move closer to each other, thereby driving the locking member 5 to move longitudinally to unlock, making the operation simple and convenient.
