Technical Field

[0001] This utility model relates to the field of unloading, and in particular to a linkage locking device. Background Technology

[0002] Currently, linkage locking devices are widely used in loading and unloading operations for various types of goods. By firmly locking the goods to the transport platform, they ensure the stability and safety of the goods during transportation. However, existing linkage locking devices generally suffer from complex and cumbersome unlocking operations, which seriously affects loading and unloading efficiency. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the current linkage locking device, the present invention can achieve synchronous unlocking and improve loading and unloading efficiency.

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

[0005] A linkage locking device includes several mounting brackets, each mounting bracket housing a locking assembly. Adjacent locking assemblies are hinged together by a straight rod, which is connected to a driving device. The upper end of each mounting bracket has a locking port. Each locking assembly includes a fixed base, a first transmission member and a second transmission member 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 straight rod. A pin passes through the through hole, allowing the first transmission member, the second transmission member, and the straight rod to rotate about their axial direction. One end of the second transmission member is connected to a locking member, which can move up and down within the locking port. The straight rod enables the locking components to lock or unlock synchronously.

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

[0007] According to one aspect of the present invention, the diameter of the limiting part is larger than the diameter of the locking part or the transmission part.

[0008] According to one aspect of the present invention, a washer is provided on the locking part.

[0009] According to one aspect of the present invention, the diameter of the washer is not greater than the diameter of the limiting portion.

[0010] According to one aspect of the present invention, the driving device is a hydraulic cylinder.

[0011] 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.

[0012] According to one aspect of the present invention, the second transmission member includes two opposing second transmission plates, and the straight rod is disposed between the two second transmission plates.

[0013] According to one aspect of the present invention, the driving device includes a base, a hydraulic cylinder, and a connecting part.

[0014] According to one aspect of the present invention, the connecting portion is disposed on the left half of the straight rod.

[0015] The advantages of this utility model are: the driving device makes the first and second transmission components move closer or further apart, thereby driving the locking component to move longitudinally to achieve locking or unlocking, which is simple and convenient to operate; the straight rod enables several locking devices to lock or unlock synchronously.

Detailed Implementation

[0023] 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.

[0024] Example 1:

[0025] like Figures 1 to 5 As shown, a linkage locking device includes several mounting brackets 6. Each mounting bracket 6 houses a locking assembly. Adjacent locking assemblies are hinged together by straight rods 9. A driving device 7 is connected to the straight rods 9. A locking port 8 is provided at the upper end of each mounting bracket 6. Each locking assembly includes a fixed base 1, a first transmission member 2 and a second transmission member 3 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 straight rod 9. A pin 4 passes through the through hole, allowing the first transmission member 2, the second transmission member 3, and the straight rod 9 to rotate around its axial direction. One end of the second transmission member 3 is connected to a locking member 5, which can move up and down within the locking port 8. The straight rods 9 enable the locking components to lock or unlock synchronously. The driving device 7 drives the straight rod 9 to move laterally, causing the first transmission member 2 and the second transmission member 3 to move closer or further apart, thereby driving the locking member 5 to move longitudinally to achieve locking or unlocking.

[0026] In use, the straight rod 9 is driven to the right by the drive device 7, which causes the first transmission component 2 and the second transmission component 3 to move closer to each other, and causes the locking component 5 to move downward to achieve unlocking. The straight rod 9 enables the locking assembly to unlock synchronously.

[0027] In practical applications, it is not necessary to limit oneself to... Figure 1 The two locking components can be set up, and multiple locking components can be set up to achieve synchronous movement through multiple straight rods 9.

[0028] In practical applications, the locking component 5 includes a locking part 51, a limiting part 52, and a transmission part 53 connected sequentially from top to bottom.

[0029] In practical applications, the diameter of the limiting part 52 is larger than the diameter of the locking 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.

[0030] In practical applications, a washer is fitted onto the locking part 51. The washer reduces wear and extends the product's service life.

[0031] In practical applications, the diameter of the washer should not exceed the diameter of the limiting part 52 to prevent uneven force on the washer.

[0032] In practical applications, the drive device 7 is a hydraulic cylinder 72.

[0033] 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.

[0034] Specifically, a washer is provided between the first transmission plate 21 and the fixed base 1. The washer reduces the lateral clearance and enhances the structural stability.

[0035] In practical applications, the second transmission component 3 includes two opposing second transmission plates 31, with the straight rod 9 positioned between the two second transmission plates 31. This results in a more robust transmission structure.

[0036] In practical applications, the straight rod 9 is connected to the hydraulic cylinder 72. Using the hydraulic cylinder 72 for operation makes the process more convenient.

[0037] The advantages of this invention are: the locking components are unlocked synchronously by the straight rod 9; the first transmission component 2 and the second transmission component 3 move closer or further apart, thereby driving the locking component 5 to move longitudinally to achieve locking or unlocking, making the operation simple and convenient.

[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
